See my answer to a similar question here.

It sounds like you want a background-image to keep it's own aspect ratio while expanding to 100% width and getting cropped off on the top and bottom. If that's the case, do something like this:

.chapter {
    position: relative;
    height: 1200px;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/3/

The problem with this approach is that you have the container elements at a fixed height, so there can be space below if the screen is small enough.

If you want the height to keep the image's aspect ratio, you'll have to do something like what I wrote in an edit to the answer I linked to above. Set the container's height to 0 and set the padding-bottom to the percentage of the width:

.chapter {
    position: relative;
    height: 0;
    padding-bottom: 75%;
    z-index: 1;
}

#chapter1 {
    background-image: url(http://omset.files.wordpress.com/2010/06/homer-simpson-1-264a0.jpg);
    background-repeat: no-repeat;
    background-size: 100% auto;
    background-position: center top;
    background-attachment: fixed;
}

jsfiddle: http://jsfiddle.net/ndKWN/4/

You could also put the padding-bottom percentage into each #chapter style if each image has a different aspect ratio. In order to use different aspect ratios, divide the height of the original image by it's own width, and multiply by 100 to get the percentage value.

None of above answer solve my problem. The fact is that my project did not have type script installed. But locally I had run npm install -g typescript. So I did not notice that typescript node dependency was not in my package json.

When I pushed it to server side, and run npm install, then npx tsc I get a tsc not found. In facts remote server did not have typescript installed. That was hidden because of my local global typescript install.

If you have some panels or groupboxes reset fields should be recursive.

public class Utilities
{
    public static void ResetAllControls(Control form)
    {
        foreach (Control control in form.Controls)
        {
            RecursiveResetForm(control);
        }
    }

    private void RecursiveResetForm(Control control)
    {            
        if (control.HasChildren)
        {
            foreach (Control subControl in control.Controls)
            {
                RecursiveResetForm(subControl);
            }
        }
        switch (control.GetType().Name)
        {
            case "TextBox":
                TextBox textBox = (TextBox)control;
                textBox.Text = null;
                break;

            case "ComboBox":
                ComboBox comboBox = (ComboBox)control;
                if (comboBox.Items.Count > 0)
                    comboBox.SelectedIndex = 0;
                break;

            case "CheckBox":
                CheckBox checkBox = (CheckBox)control;
                checkBox.Checked = false;
                break;

            case "ListBox":
                ListBox listBox = (ListBox)control;
                listBox.ClearSelected();
                break;

            case "NumericUpDown":
                NumericUpDown numericUpDown = (NumericUpDown)control;
                numericUpDown.Value = 0;
                break;
        }
    }        
}

I have made somthink like this for one of my website accualy in developpement.

I have used StepCarousel for the caroussel because it's the only one I found that can accept different image size in the same carrousel.

In addition to this to add the touch swipe effect, I have used jquery.touchswipe plugin;

And stepcarousel move panel rigth or left with a fonction so I can make :

$("#slider-actu").touchwipe({
    wipeLeft: function() {stepcarousel.stepBy('slider-actu', 3);},
    wipeRight: function() {stepcarousel.stepBy('slider-actu', -3);},
    min_move_x: 20
});

Hope that help you.

One notice. On Windows, place your _curlrc in '%APPDATA%' or '%USERPROFILE%\Application Data'.

From RFC 3986:

A URI can be further classified as a locator, a name, or both. The term "Uniform Resource Locator" (URL) refers to the subset of URIs that, in addition to identifying a resource, provide a means of locating the resource by describing its primary access mechanism (e.g., its network "location"). The term "Uniform Resource Name" (URN) has been used historically to refer to both URIs under the "urn" scheme [RFC2141], which are required to remain globally unique and persistent even when the resource ceases to exist or becomes unavailable, and to any other URI with the properties of a name.

So all URLs are URIs, and all URNs are URIs - but URNs and URLs are different, so you can't say that all URIs are URLs.

If you haven't already read Roger Pate's answer, I'd advise doing so as well.

You could also use a URI template. If you structured your request into a restful URL Spring could parse the provided value from the url.

HTML

<li>
    <a id="byParameter" 
       class="textLink" href="<c:url value="/mapping/parameter/bar />">By path, method,and
           presence of parameter</a>
</li>

Controller

@RequestMapping(value="/mapping/parameter/{foo}", method=RequestMethod.GET)
public @ResponseBody String byParameter(@PathVariable String foo) {
    //Perform logic with foo
    return "Mapped by path + method + presence of query parameter! (MappingController)";
}

Often used with/as a part of OOAD and business modeling. The definition by Neil is correct, but it is basically identical to MVC, but just abstracted for the business. The "Good summary" is well done so I will not copy it here as it is not my work, more detailed but inline with Neil's bullet points.

Alternatively, you can use requests.Session and observe cookies before and after a request:

>>> import requests
>>> session = requests.Session()
>>> print(session.cookies.get_dict())
{}
>>> response = session.get('http://google.com')
>>> print(session.cookies.get_dict())
{'PREF': 'ID=5514c728c9215a9a:FF=0:TM=1406958091:LM=1406958091:S=KfAG0U9jYhrB0XNf', 'NID': '67=TVMYiq2wLMNvJi5SiaONeIQVNqxSc2RAwVrCnuYgTQYAHIZAGESHHPL0xsyM9EMpluLDQgaj3db_V37NjvshV-eoQdA8u43M8UwHMqZdL-S2gjho8j0-Fe1XuH5wYr9v'}

Create a new custom object and add it to the object array that Import-Csv creates.

$fileContent = Import-csv $file -header "Date", "Description"
$newRow = New-Object PsObject -Property @{ Date = 'Text4' ; Description = 'Text5' }
$fileContent += $newRow

The sqlite team published an article explaining when to use sqlite that is great read. Basically, you want to avoid using sqlite when you have a lot of write concurrency or need to scale to terabytes of data. In many other cases, sqlite is a surprisingly good alternative to a "traditional" database such as MySQL.

From the documentation:

A channel may be closed with the built-in function close. The multi-valued assignment form of the receive operator reports whether a received value was sent before the channel was closed.

https://golang.org/ref/spec#Receive_operator

Example by Golang in Action shows this case:

// This sample program demonstrates how to use an unbuffered
// channel to simulate a game of tennis between two goroutines.
package main

import (
    "fmt"
    "math/rand"
    "sync"
    "time"
)

// wg is used to wait for the program to finish.
var wg sync.WaitGroup

func init() {
    rand.Seed(time.Now().UnixNano())
}

// main is the entry point for all Go programs.
func main() {
    // Create an unbuffered channel.
    court := make(chan int)
    // Add a count of two, one for each goroutine.
    wg.Add(2)
    // Launch two players.
    go player("Nadal", court)
    go player("Djokovic", court)
    // Start the set.
    court <- 1
    // Wait for the game to finish.
    wg.Wait()
}

// player simulates a person playing the game of tennis.
func player(name string, court chan int) {
    // Schedule the call to Done to tell main we are done.
    defer wg.Done()
    for {
        // Wait for the ball to be hit back to us.
        ball, ok := <-court
        fmt.Printf("ok %t\n", ok)
        if !ok {
            // If the channel was closed we won.
            fmt.Printf("Player %s Won\n", name)
            return
        }
        // Pick a random number and see if we miss the ball.
        n := rand.Intn(100)
        if n%13 == 0 {
            fmt.Printf("Player %s Missed\n", name)
            // Close the channel to signal we lost.
            close(court)
            return
        }

        // Display and then increment the hit count by one.
        fmt.Printf("Player %s Hit %d\n", name, ball)
        ball++
        // Hit the ball back to the opposing player.
        court <- ball
    }
}

I find Selenium tests more useful with integration or functional (end-to-end) testing. I am working with trying to use org.springframework.mock.web, but I am not very far along. I am attaching a sample controller with a jMock test suite.

First, the Controller:

package com.company.admin.web;

import javax.validation.Valid;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.stereotype.Controller;
import org.springframework.ui.Model;
import org.springframework.validation.BindingResult;

import org.springframework.web.bind.annotation.ModelAttribute;
import org.springframework.web.bind.annotation.RequestMapping;
import org.springframework.web.bind.annotation.RequestMethod;
import org.springframework.web.bind.annotation.SessionAttributes;
import org.springframework.web.bind.support.SessionStatus;

import com.company.admin.domain.PaymentDetail;
import com.company.admin.service.PaymentSearchService;
import com.company.admin.service.UserRequestAuditTrail;
import com.company.admin.web.form.SearchCriteria;

/**
 * Controls the interactions regarding to the refunds.
 * 
 * @author slgelma

 */
@Controller
@SessionAttributes({"user", "authorization"})
public class SearchTransactionController {

    public static final String SEARCH_TRANSACTION_PAGE = "searchtransaction";

    private PaymentSearchService searchService;
    //private Validator searchCriteriaValidator;
    private UserRequestAuditTrail notifications;

    @Autowired
    public void setSearchService(PaymentSearchService searchService) {
        this.searchService = searchService;
    }

    @Autowired
    public void setNotifications(UserRequestAuditTrail notifications) {
        this.notifications = notifications;
    }

    @RequestMapping(value="/" + SEARCH_TRANSACTION_PAGE)
    public String setUpTransactionSearch(Model model) {
        SearchCriteria searchCriteria = new SearchCriteria();
        model.addAttribute("searchCriteria", searchCriteria);
        notifications.transferTo(SEARCH_TRANSACTION_PAGE);
        return SEARCH_TRANSACTION_PAGE;
    }

    @RequestMapping(value="/" + SEARCH_TRANSACTION_PAGE, method=RequestMethod.POST, params="cancel")
    public String cancelSearch() {
        notifications.redirectTo(HomeController.HOME_PAGE);
        return "redirect:/" + HomeController.HOME_PAGE;
    }

    @RequestMapping(value="/" + SEARCH_TRANSACTION_PAGE, method=RequestMethod.POST, params="execute")
    public String executeSearch(
            @ModelAttribute("searchCriteria") @Valid SearchCriteria searchCriteria,
            BindingResult result, Model model,
            SessionStatus status) {
        //searchCriteriaValidator.validate(criteria, result);
        if (result.hasErrors()) {
            notifications.transferTo(SEARCH_TRANSACTION_PAGE);
            return SEARCH_TRANSACTION_PAGE;
        } else {
            PaymentDetail payment = 
                searchService.getAuthorizationFor(searchCriteria.geteWiseTransactionId());
            if (payment == null) {
                ObjectError error = new ObjectError(
                        "eWiseTransactionId", "Transaction not found");
                result.addError(error);
                model.addAttribute("searchCriteria", searchCriteria);
                notifications.transferTo(SEARCH_TRANSACTION_PAGE);
                return SEARCH_TRANSACTION_PAGE;
            } else {
                model.addAttribute("authorization", payment);
                notifications.redirectTo(PaymentDetailController.PAYMENT_DETAIL_PAGE);
                return "redirect:/" + PaymentDetailController.PAYMENT_DETAIL_PAGE;
            }
        }
    }

}

I hope this might help.

If you are including a library which depends on another library, then the order of inclusion is also important:

g++ -o MyApp MyMain.o -lMyLib1 -lMyLib2

In this case, it is okay if MyLib1 depends on MyLib2. However, if there reverse is true, you will get undefined references.

Try rebooting (if it was ever detected before and stopped showing up) - the mother of all solutions!

I think you're looking for Hping (http://www.hping.org/), which has a Windows version.

"The interface is inspired to the ping(8) unix command, but hping isn't only able to send ICMP echo requests. It supports TCP, UDP, ICMP..."

It's also very useful if you want to see where along a route that a TCP port is being blocked (like by a firewall), where ICMP might not be.

Solved this by adding following

RewriteCond %{ENV:REDIRECT_STATUS} 200 [OR]
 RewriteCond %{REQUEST_FILENAME} -f [OR]
 RewriteCond %{REQUEST_FILENAME} -d
 RewriteRule ^ - [L]

There are many ways in which you can create unique keys, the simplest method is to use the index when iterating arrays.

Example

    var lists = this.state.lists.map(function(list, index) {
        return(
            <div key={index}>
                <div key={list.name} id={list.name}>
                    <h2 key={"header"+list.name}>{list.name}</h2>
                    <ListForm update={lst.updateSaved} name={list.name}/>
                </div>
            </div>
        )
    });

Wherever you're lopping over data, here this.state.lists.map, you can pass second parameter function(list, index) to the callback as well and that will be its index value and it will be unique for all the items in the array.

And then you can use it like

<div key={index}>

You can do the same here as well

    var savedLists = this.state.savedLists.map(function(list, index) {
        var list_data = list.data;
        list_data.map(function(data, index) {
            return (
                <li key={index}>{data}</li>
            )
        });
        return(
            <div key={index}>
                <h2>{list.name}</h2>
                <ul>
                    {list_data}
                </ul>
            </div>
        )
    });

Edit

However, As pointed by the user Martin Dawson in the comment below, This is not always ideal.

So whats the solution then?

Many

• You can create a function to generate unique keys/ids/numbers/strings and use that
• You can make use of existing npm packages like uuid, uniqid, etc
• You can also generate random number like new Date().getTime(); and prefix it with something from the item you're iterating to guarantee its uniqueness
• Lastly, I recommend using the unique ID you get from the database, If you get it.

Example:

const generateKey = (pre) => {
    return `${ pre }_${ new Date().getTime() }`;
}

const savedLists = this.state.savedLists.map( list => {
    const list_data = list.data.map( data => <li key={ generateKey(data) }>{ data }</li> );
    return(
        <div key={ generateKey(list.name) }>
            <h2>{ list.name }</h2>
            <ul>
                { list_data }
            </ul>
        </div>
    )
});

I used @timestamp instead of _timestamp

{
    'size' : 1,
    'query': {
        'match_all' : {}
            },
    "sort" : [{"@timestamp":{"order": "desc"}}]
}

Although formatting belongs to the Presentation layer, SQL Server 2012 and above versions provide FORMAT() function which provides one of the quickest and easiest way to format output. Here are some tips & examples:

Syntax: Format( value, format [, culture ] )

Returns: Format function returns NVarchar string formatted with the specified format and with optional culture. (Returns NULL for invalid format-string.)

Note: The Format() function is consistent across CLR / all .NET languages and provides maximum flexibility to generate formatted output.

Following are few format types that can be achieved using this function:

• Numeric/Currency formatting - 'C' for currency, 'N' number without currency symbol, 'x' for Hexa-decimals.

• Date/Time formatting - 'd' short date, 'D' long date, 'f' short full date/time, 'F' long full date/time, 't' short time, 'T' long time, 'm' month+day, 'y' year+month.

• Custom formatting - you can form your own-custom format using certain symbols/characters, such as dd, mm, yyyy etc. (for Dates). hash (#) currency symbols (£ $ etc.), comma(,) and so on. See examples below.

Examples:

Examples of Built-in Numeric/Currency Formats:

?   select FORMAT(1500350.75, 'c', 'en-gb') --> £1,500,350.75
?   select FORMAT(1500350.75, 'c', 'en-au') --> $1,500,350.75
?   select FORMAT(1500350.75, 'c', 'en-in') --> ? 15,00,350.75

Examples of Built-in Date Formats:

?   select FORMAT(getdate(), 'd', 'en-gb') --> 20/06/2017
?   select FORMAT(getdate(), 'D', 'fr-fr') --> mardi 20 juin 2017
?   select FORMAT(getdate(), 'F', 'en-us') --> Tuesday, June 20, 2017 10:41:39 PM
?   select FORMAT(getdate(), 'T', 'en-gb') --> 22:42:29

Examples of Custom Formatting:

?   select FORMAT(GETDATE(), 'ddd  dd/MM/yyyy')  --> Tue 20/06/2017
?   select FORMAT(GETDATE(), 'dddd dd-MMM-yyyy') --> Tuesday 20-Jun-2017
?   select FORMAT(GETDATE(), 'dd.MMMM.yyyy HH:mm:ss') --> 20.June.2017 22:47:20
?   select FORMAT(123456789.75,'$#,#.00')  --> $123,456,789.75
?   select FORMAT(123456789.75,'£#,#.0')   --> £123,456,789.8

See MSDN for more information on FORMAT() function.

For SQL Server 2008 or below convert the output to MONEY first then to VARCHAR (passing "1" for the 3rd argument of CONVERT() function to specify the "style" of output-format), e.g.:

?   select CONVERT(VARCHAR, CONVERT(MONEY, 123456789.75), 1)    --> 123,456,789.75

You probably don't want to pass the car object as a parameter, try just passing car.id. What do you get when you inspect(params) after clicking "Add to cart"?

I found out this solution .

set the selectedIndex of select element to 0 initially

//set selected Index to 0

doSomethingOnChange(){

     blah ..blah ..

     set selected Index to 0

}

call this method onChange event

I know this is old, but most of these answers require a ton of extra code.

If you have a light colored background, you can simply use this:

android:elevation="25dp"

An example PUT following Martin C. Martin's comment:

curl -T filename.txt http://www.example.com/dir/

With -T (same as --upload-file) curl will use PUT for HTTP.

Well Facebook has undergone MANY many changes and it wasn't originally designed to be efficient. It was designed to do it's job. I have absolutely no idea what the code looks like and you probably won't find much info about it (for obvious security and copyright reasons), but just take a look at the API. Look at how often it changes and how much of it doesn't work properly, anymore, or at all.

I think the biggest ace up their sleeve is the Hiphop. http://developers.facebook.com/blog/post/358 You can use HipHop yourself: https://github.com/facebook/hiphop-php/wiki

But if you ask me it's a very ambitious and probably time wasting task. Hiphop only supports so much, it can't simply convert everything to C++. So what does this tell us? Well, it tells us that Facebook is NOT fully taking advantage of the PHP language. It's not using the latest 5.3 and I'm willing to bet there's still a lot that is PHP 4 compatible. Otherwise, they couldn't use HipHop. HipHop IS A GOOD IDEA and needs to grow and expand, but in it's current state it's not really useful for that many people who are building NEW PHP apps.

There's also PHP to JAVA via things like Resin/Quercus. Again, it doesn't support everything...

Another thing to note is that if you use any non-standard PHP module, you aren't going to be able to convert that code to C++ or Java either. However...Let's take a look at PHP modules. They are ARE compiled in C++. So if you can build PHP modules that do things (like parse XML, etc.) then you are basically (minus some interaction) working at the same speed. Of course you can't just make a PHP module for every possible need and your entire app because you would have to recompile and it would be much more difficult to code, etc.

However...There are some handy PHP modules that can help with speed concerns. Though at the end of the day, we have this awesome thing known as "the cloud" and with it, we can scale our applications (PHP included) so it doesn't matter as much anymore. Hardware is becoming cheaper and cheaper. Amazon just lowered it's prices (again) speaking of.

So as long as you code your PHP app around the idea that it will need to one day scale...Then I think you're fine and I'm not really sure I'd even look at Facebook and what they did because when they did it, it was a completely different world and now trying to hold up that infrastructure and maintain it...Well, you get things like HipHop.

Now how is HipHop going to help you? It won't. It can't. You're starting fresh, you can use PHP 5.3. I'd highly recommend looking into PHP 5.3 frameworks and all the new benefits that PHP 5.3 brings to the table along with the SPL libraries and also think about your database too. You're most likely serving up content from a database, so check out MongoDB and other types of databases that are schema-less and document-oriented. They are much much faster and better for the most "common" type of web site/app.

Look at NEW companies like Foursquare and Smugmug and some other companies that are utilizing NEW technology and HOW they are using it. For as successful as Facebook is, I honestly would not look at them for "how" to build an efficient web site/app. I'm not saying they don't have very (very) talented people that work there that are solving (their) problems creatively...I'm also not saying that Facebook isn't a great idea in general and that it's not successful and that you shouldn't get ideas from it....I'm just saying that if you could view their entire source code, you probably wouldn't benefit from it.

One important difference is that you can only inherit one base class, but you can implement many interfaces. So you only want to use a base class if you are absolutely certain that you won't need to also inherit a different base class. Additionally, if you find your interface is getting large then you should start looking to break it up into a few logical pieces that define independent functionality, since there's no rule that your class can't implement them all (or that you can define a different interface that just inherits them all to group them).

With Swift 5 and iOS 12.3, according to your needs, you may choose one of the 3 following ways in order to solve your problem.

#1. Using UIView's animate(withDuration:animations:) class method

animate(withDuration:animations:) has the following declaration:

Animate changes to one or more views using the specified duration.

class func animate(withDuration duration: TimeInterval, animations: @escaping () -> Void)

The Playground code below shows a possible implementation of animate(withDuration:animations:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIView.animate(withDuration: 2) {
            self.view.layoutIfNeeded()
        }
    }

}

PlaygroundPage.current.liveView = ViewController()

#2. Using UIViewPropertyAnimator's init(duration:curve:animations:) initialiser and startAnimation() method

init(duration:curve:animations:) has the following declaration:

Initializes the animator with a built-in UIKit timing curve.

convenience init(duration: TimeInterval, curve: UIViewAnimationCurve, animations: (() -> Void)? = nil)

The Playground code below shows a possible implementation of init(duration:curve:animations:) and startAnimation() in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        let animator = UIViewPropertyAnimator(duration: 2, curve: .linear, animations: {
            self.view.layoutIfNeeded()
        })
        animator.startAnimation()
    }

}

PlaygroundPage.current.liveView = ViewController()

#3. Using UIViewPropertyAnimator's runningPropertyAnimator(withDuration:delay:options:animations:completion:) class method

runningPropertyAnimator(withDuration:delay:options:animations:completion:) has the following declaration:

Creates and returns an animator object that begins running its animations immediately.

class func runningPropertyAnimator(withDuration duration: TimeInterval, delay: TimeInterval, options: UIViewAnimationOptions = [], animations: @escaping () -> Void, completion: ((UIViewAnimatingPosition) -> Void)? = nil) -> Self

The Playground code below shows a possible implementation of runningPropertyAnimator(withDuration:delay:options:animations:completion:) in order to animate an Auto Layout constraint's constant change.

import UIKit
import PlaygroundSupport

class ViewController: UIViewController {

    let textView = UITextView()
    lazy var heightConstraint = textView.heightAnchor.constraint(equalToConstant: 50)

    override func viewDidLoad() {
        view.backgroundColor = .white
        view.addSubview(textView)

        textView.backgroundColor = .orange
        textView.isEditable = false
        textView.text = "Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.

Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum."

        textView.translatesAutoresizingMaskIntoConstraints = false
        textView.topAnchor.constraint(equalToSystemSpacingBelow: view.layoutMarginsGuide.topAnchor, multiplier: 1).isActive = true
        textView.leadingAnchor.constraint(equalTo: view.layoutMarginsGuide.leadingAnchor).isActive = true
        textView.trailingAnchor.constraint(equalTo: view.layoutMarginsGuide.trailingAnchor).isActive = true
        heightConstraint.isActive = true

        let tapGesture = UITapGestureRecognizer(target: self, action: #selector(doIt(_:)))
        textView.addGestureRecognizer(tapGesture)
    }

    @objc func doIt(_ sender: UITapGestureRecognizer) {
        heightConstraint.constant = heightConstraint.constant == 50 ? 150 : 50
        UIViewPropertyAnimator.runningPropertyAnimator(withDuration: 2, delay: 0, options: [], animations: {
            self.view.layoutIfNeeded()
        })
    }

}

PlaygroundPage.current.liveView = ViewController()

I was looking for a way to format numbers without leading or trailing spaces, periods, zeros (except one leading zero for numbers less than 1 that should be present).

This is frustrating that such most usual formatting can't be easily achieved in Oracle.

Even Tom Kyte only suggested long complicated workaround like this:

case when trunc(x)=x
    then to_char(x, 'FM999999999999999999')
    else to_char(x, 'FM999999999999999.99')
end x

But I was able to find shorter solution that mentions the value only once:

rtrim(to_char(x, 'FM999999999999990.99'), '.')

This works as expected for all possible values:

select 
    to_char(num, 'FM99.99') wrong_leading_period,
    to_char(num, 'FM90.99') wrong_trailing_period,
    rtrim(to_char(num, 'FM90.99'), '.') correct
from (
  select num from (select 0.25 c1, 0.1 c2, 1.2 c3, 13 c4, -70 c5 from dual)
  unpivot (num for dummy in (c1, c2, c3, c4, c5))
) sampledata;

    | WRONG_LEADING_PERIOD | WRONG_TRAILING_PERIOD | CORRECT |
    |----------------------|-----------------------|---------|
    |                  .25 |                  0.25 |    0.25 |
    |                   .1 |                   0.1 |     0.1 |
    |                  1.2 |                   1.2 |     1.2 |
    |                  13. |                   13. |      13 |
    |                 -70. |                  -70. |     -70 |

Still looking for even shorter solution.

There is a shortening approarch with custom helper function:

create or replace function str(num in number) return varchar2
as
begin
    return rtrim(to_char(num, 'FM999999999999990.99'), '.');
end;

But custom pl/sql functions have significant performace overhead that is not suitable for heavy queries.

Sorry for late reply but still felt like posting my answer if it helps.It works for 6 digits OTP.

    @Override
    public void onOTPReceived(String messageBody)
    {
        Pattern pattern = Pattern.compile(SMSReceiver.OTP_REGEX);
        Matcher matcher = pattern.matcher(messageBody);
        String otp = HkpConstants.EMPTY;
        while (matcher.find())
        {
            otp = matcher.group();
        }
        checkAndSetOTP(otp);
    }
Adding constants here

public static final String OTP_REGEX = "[0-9]{1,6}";

For SMS listener one can follow the below class

public class SMSReceiver extends BroadcastReceiver
{
    public static final String SMS_BUNDLE = "pdus";
    public static final String OTP_REGEX = "[0-9]{1,6}";
    private static final String FORMAT = "format";

    private OnOTPSMSReceivedListener otpSMSListener;

    public SMSReceiver(OnOTPSMSReceivedListener listener)
    {
        otpSMSListener = listener;
    }

    @Override
    public void onReceive(Context context, Intent intent)
    {
        Bundle intentExtras = intent.getExtras();
        if (intentExtras != null)
        {
            Object[] sms_bundle = (Object[]) intentExtras.get(SMS_BUNDLE);
            String format = intent.getStringExtra(FORMAT);
            if (sms_bundle != null)
            {
                otpSMSListener.onOTPSMSReceived(format, sms_bundle);
            }
            else {
                // do nothing
            }
        }
    }

    @FunctionalInterface
    public interface OnOTPSMSReceivedListener
    {
        void onOTPSMSReceived(@Nullable String format, Object... smsBundle);
    }
}

    @Override
    public void onOTPSMSReceived(@Nullable String format, Object... smsBundle)
    {
        for (Object aSmsBundle : smsBundle)
        {
            SmsMessage smsMessage = getIncomingMessage(format, aSmsBundle);
            String sender = smsMessage.getDisplayOriginatingAddress();
            if (sender.toLowerCase().contains(ONEMG))
            {
                getIncomingMessage(smsMessage.getMessageBody());
            } else
            {
                // do nothing
            }
        }
    }

    private SmsMessage getIncomingMessage(@Nullable String format, Object aObject)
    {
        SmsMessage currentSMS;
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && format != null)
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject, format);
        } else
        {
            currentSMS = SmsMessage.createFromPdu((byte[]) aObject);
        }

        return currentSMS;
    }

I had the same problem. Wound up just writing a custom highlight and unhighlight function for the validator. Adding this to the validaton options should add the error class to the element and its respective label:

        'highlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").addClass(errorClass);
                    $(this).addClass(errorClass);
                });
            } else {
                $(element.form).find("label[for=" + element.id + "]").addClass(errorClass);
                $(element).addClass(errorClass);
            }
        },
        'unhighlight': function (element, errorClass, validClass) {
            if($(element).attr('type') == 'radio'){
                $(element.form).find("input[type=radio]").each(function(which){
                    $(element.form).find("label[for=" + this.id + "]").removeClass(errorClass);
                    $(this).removeClass(errorClass);
                });
            }else {
                $(element.form).find("label[for=" + element.id + "]").removeClass(errorClass);
                $(element).removeClass(errorClass);
            }
        },

I am just adding example here because I think examples make it easier to understand.

In printf() they behave identically so you can use any either %d or %i. But they behave differently in scanf().

For example:

int main()
{
    int num,num2;
    scanf("%d%i",&num,&num2);// reading num using %d and num2 using %i

    printf("%d\t%d",num,num2);
    return 0;
}

Output:

You can see the different results for identical inputs.

num:

We are reading num using %d so when we enter 010 it ignores the first 0 and treats it as decimal 10.

num2:

We are reading num2 using %i.

That means it will treat decimals, octals, and hexadecimals differently.

When it give num2 010 it sees the leading 0 and parses it as octal.

When we print it using %d it prints the decimal equivalent of octal 010 which is 8.

In general this error message means that you have tried to use indexing on a function. You can reproduce this error message with, for example

mean[1]
## Error in mean[1] : object of type 'closure' is not subsettable
mean[[1]]
## Error in mean[[1]] : object of type 'closure' is not subsettable
mean$a
## Error in mean$a : object of type 'closure' is not subsettable

The closure mentioned in the error message is (loosely) the function and the environment that stores the variables when the function is called.

In this specific case, as Joshua mentioned, you are trying to access the url function as a variable. If you define a variable named url, then the error goes away.

As a matter of good practise, you should usually avoid naming variables after base-R functions. (Calling variables data is a common source of this error.)

There are several related errors for trying to subset operators or keywords.

`+`[1]
## Error in `+`[1] : object of type 'builtin' is not subsettable
`if`[1]
## Error in `if`[1] : object of type 'special' is not subsettable

If you're running into this problem in shiny, the most likely cause is that you're trying to work with a reactive expression without calling it as a function using parentheses.

library(shiny)
reactive_df <- reactive({
    data.frame(col1 = c(1,2,3),
               col2 = c(4,5,6))
})

While we often work with reactive expressions in shiny as if they were data frames, they are actually functions that return data frames (or other objects).

isolate({
    print(reactive_df())
    print(reactive_df()$col1)
})
  col1 col2
1    1    4
2    2    5
3    3    6
[1] 1 2 3

But if we try to subset it without parentheses, then we're actually trying to index a function, and we get an error:

isolate(
    reactive_df$col1
)
Error in reactive_df$col1 : object of type 'closure' is not subsettable

The proper Swift operator is is:

if touch.view is UIPickerView {
    // touch.view is of type UIPickerView
}

Of course, if you also need to assign the view to a new constant, then the if let ... as? ... syntax is your boy, as Kevin mentioned. But if you don't need the value and only need to check the type, then you should use the is operator.

This is basically the same answer as posted by @TristanLorach, just recoded for Swift 3:

Here's how to do it.Suppose the following messageLabel is the label you want to have the desired effect.Now,try these simple line of codes:

    //SET THE WIDTH CONSTRAINTS FOR LABEL.
    CGFloat constrainedWidth = 240.0f;//YOU CAN PUT YOUR DESIRED ONE,THE MAXIMUM WIDTH OF YOUR LABEL.
 //CALCULATE THE SPACE FOR THE TEXT SPECIFIED.
    CGSize sizeOfText=[yourText sizeWithFont:yourFont constrainedToSize:CGSizeMake(constrainedWidth, CGFLOAT_MAX) lineBreakMode:UILineBreakModeWordWrap];
    UILabel *messageLabel=[[UILabel alloc] initWithFrame:CGRectMake(20,20,constrainedWidth,sizeOfText.height)];
    messageLabel.text=yourText;
    messageLabel.numberOfLines=0;//JUST TO SUPPORT MULTILINING.

Since Flask 0.10 you can`t add multiple routes to one endpoint. But you can add fake endpoint

@user.route('/<userId>')
def show(userId):
   return show_with_username(userId)

@user.route('/<userId>/<username>')
def show_with_username(userId,username=None):
   pass

Quick Answer:

git stash pop -> remove from the stash list

git stash apply -> keep it in the stash list

Note that the jQuery solutions that normalize height on here may break with IE.

After some testing (with Bootstrap 3) it looks like IE doesn't bother resizing images unless they're actually being rendered. If you make the window smaller, the image of the active item gets resized but the background images preserve their height, so the "tallest" height stays the same.

In my case we were only rendering images on these items, and the images were only ever a few pixels off. So I opted to style all of the images with the height of the active image. Everything else gets resized to fit the height, so keep that in mind if your aspect ratios vary a lot.

    function carouselNormalization() {
        var items = $('.carousel .item');

        if (items.length) {
            function normalizeHeights() {
                let activeImageHeight = items.filter('.active').find('img').height();
                items.each(function() {
                    $(this).find('img').css('height',  activeImageHeight + 'px');
                });
            };
            normalizeHeights();

            $(window).on('resize orientationchange', function() {
                items.each(function() {
                    $(this).find('img').removeAttr('style');
                });
                normalizeHeights();
            });
        }
    }
    $(window).on('load', carouselNormalization);

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

As already noted the approach for resetting the notification state for an app on a device is changed for iOS5 an newer.

This works for me on iOS6:

• Remove the app from the device
• Set the device datetime two days or more ahead
• Restart the device
• Set the device datetime two days or more ahead
• Restart the device
• Install and run the app again

However this will only make the initial prompt appear again - it will not remove any other push state related stuff.

1. No, this doesn't mean network is slow.
2. No, this is not only false warning.

I have this problem on angular web applications after replace link https://fonts.googleapis.com/icon?family=Material+Icons in index.html to integrated version (npm install .... material-icons...). This works, but sometimes web application show that warning.

When warning is shown icons are not rendered for approximately 1 second, so user see badly rendered icons.

I don't have solution yet.

The easiest way for Windows!

Download the latest version of geckodriver from here. Add the geckodriver.exe file to the Python directory (or any other directory which already in PATH). This should solve the problem (it was tested on Windows 10).

As already pointed out by others, all the solutions above only change the working directory of the current process. This is lost when you exit back to the Unix shell. If desperate you can change the parent shell directory on Unix with this horrible hack:

def quote_against_shell_expansion(s):
    import pipes
    return pipes.quote(s)

def put_text_back_into_terminal_input_buffer(text):
    # use of this means that it only works in an interactive session
    # (and if the user types while it runs they could insert characters between the characters in 'text'!)
    import fcntl, termios
    for c in text:
        fcntl.ioctl(1, termios.TIOCSTI, c)

def change_parent_process_directory(dest):
    # the horror
    put_text_back_into_terminal_input_buffer("cd "+quote_against_shell_expansion(dest)+"\n")

When you

• updated to Mojave 10.14.6
• your /usr/include was deleted again
• the package mentioned in @Jonathan-lefflers answer doesn't exist anymore The file /Library/Developer/CommandLineTools/Packages/macOS_SDK_headers_for_macOS_10.14.pkg does not exist. and
• Xcode complains that command line tools are already installed xcode-select --install xcode-select: error: command line tools are already installed, use "Software Update" to install updates

Then, what helped me recover the mentioned package, was deleting the whole CommandLineTools folder (sudo) rm -rf /Library/Developer/CommandLineTools and reinstall it xcode-select --install.

Fitting a moving average to your data would smooth out the noise, see this this answer for how to do that.

If you'd like to use LOWESS to fit your data (it's similar to a moving average but more sophisticated), you can do that using the statsmodels library:

import numpy as np
import pylab as plt
import statsmodels.api as sm

x = np.linspace(0,2*np.pi,100)
y = np.sin(x) + np.random.random(100) * 0.2
lowess = sm.nonparametric.lowess(y, x, frac=0.1)

plt.plot(x, y, '+')
plt.plot(lowess[:, 0], lowess[:, 1])
plt.show()

Finally, if you know the functional form of your signal, you could fit a curve to your data, which would probably be the best thing to do.

Addition to @MarkR answer - one thing to note would be that many PHP frameworks with ORMs would not recognize or use advanced DB setup (foreign keys, cascading delete, unique constraints), and this may result in unexpected behaviour.

For example if you delete a record using ORM, and your DELETE CASCADE will delete records in related tables, ORM's attempt to delete these related records (often automatic) will result in error.

Looks like you use %p: Print Pointers

NEW_VAR=""
if [[ ${ENV_VAR} && ${ENV_VAR-x} ]]; then
  NEW_VAR=${ENV_VAR}
else
  NEW_VAR="new value"
fi

The last place I had to unbox something was when writing some code that retrieved some data from a database (I wasn't using LINQ to SQL, just plain old ADO.NET):

int myIntValue = (int)reader["MyIntValue"];

Basically, if you're working with older APIs before generics, you'll encounter boxing. Other than that, it isn't that common.

You can also use the pipeline stage to perform checks on a sub-docunment array

Here's the example using python (sorry I'm snake people).

db.products.aggregate([
  { '$lookup': {
      'from': 'products',
      'let': { 'pid': '$products' },
      'pipeline': [
        { '$match': { '$expr': { '$in': ['$_id', '$$pid'] } } }
        // Add additional stages here 
      ],
      'as':'productObjects'
  }
])

The catch here is to match all objects in the ObjectId array (foreign _id that is in local field/prop products).

You can also clean up or project the foreign records with additional stages, as indicated by the comment above.

I think this will work for you.

class A(object):
    def __init__(self, a, b, c, sum, version='old'):
        self.a = a
        self.b = b
        self.c = c
        self.sum = 6
        self.version = version

    def __int__(self):
        return self.sum + 9000

    def __iter__(self):
        return self.__dict__.iteritems()

a = A(1,2,3,4,5)
print dict(a)

Output

{'a': 1, 'c': 3, 'b': 2, 'sum': 6, 'version': 5}

Bit masking is "useful" to use when you want to store (and subsequently extract) different data within a single data value.

An example application I've used before is imagine you were storing colour RGB values in a 16 bit value. So something that looks like this:

RRRR RGGG GGGB BBBB

You could then use bit masking to retrieve the colour components as follows:

  const unsigned short redMask   = 0xF800;
  const unsigned short greenMask = 0x07E0;
  const unsigned short blueMask  = 0x001F;

  unsigned short lightGray = 0x7BEF;

  unsigned short redComponent   = (lightGray & redMask) >> 11;
  unsigned short greenComponent = (lightGray & greenMask) >> 5;
  unsigned short blueComponent =  (lightGray & blueMask);

Ran into this scenario today as well where I didn't want zero to be overwritten for several values. We have a file with some common utility methods for scenarios like this. Here's what I added to handle the scenario and be flexible.

function getIfNotSet(value, newValue, overwriteNull, overwriteZero) {
    if (typeof (value) === 'undefined') {
        return newValue;
    } else if (value === null && overwriteNull === true) {
        return newValue;
    } else if (value === 0 && overwriteZero === true) {
        return newValue;
    } else {
        return value;
    }
}

It can then be called with the last two parameters being optional if I want to only set for undefined values or also overwrite null or 0 values. Here's an example of a call to it that will set the ID to -1 if the ID is undefined or null, but wont overwrite a 0 value.

data.ID = Util.getIfNotSet(data.ID, -1, true);

you can use below code to get key : String [] keys = (String[]) item.keySet().toArray(new String[0]);

and get object or list that insert in HashMap with key of this item like this : item.get(keys[position]);

Dont know if someone else has this problem but wrapping my TextBlock into a ScrollViewer somewhow messed up my UI - as a simple workaround I figured out that replacing the TextBlock by a TextBox like this one

<TextBox  Name="textBlock" SelectionBrush="Transparent" Cursor="Arrow" IsReadOnly="True" Text="My Text" VerticalScrollBarVisibility="Auto">

creates a TextBox that looks and behaves like a TextBlock with a scrollbar (and you can do it all in the designer).

Type this:

mysql --help 

Then look at the output. There is a block of text about 3/4 the way down describing what files it finds its defaults .my.cnf from. Here is an example from XAMPP v3.2.1:

Default options are read from the following files in the given order:
C:\Windows\my.ini C:\Windows\my.cnf C:\my.ini C:\my.cnf C:\xampp\mysql\my.ini C:\xampp\mysql\my.cnf C:\xampp\mysql\bin\my.ini C:\xampp\mysql\bin\my.cnf

Your setup may differ. You will have to run the command to check the actual paths on your particular system.

Downgrading the JRE from 7 to 6 fixed this issue for me.

Construct a Random object at application startup:

Random random = new Random();

Then use Random.nextInt(int):

int randomNumber = random.nextInt(max + 1 - min) + min;

Note that the both lower and upper limits are inclusive.

Suppose we have a dictionary like this

Dictionary<int,string> dict = new Dictionary<int, string>();
dict.Add(1, "Mohan");
dict.Add(2, "Kishor");
dict.Add(3, "Pankaj");
dict.Add(4, "Jeetu");

We can initialize it as follow.

Dictionary<int, string> dict = new Dictionary<int, string>  
{
    { 1, "Mohan" },
    { 2, "Kishor" },
    { 3, "Pankaj" },
    { 4, "Jeetu" }
};

I had a similar use case during testing hibernate event listeners which are only called on commit.

The solution was to wrap the code to be persistent into another method annotated with REQUIRES_NEW. (In another class) This way a new transaction is spawned and a flush/commit is issued once the method returns.

Keep in mind that this might influence all the other tests! So write them accordingly or you need to ensure that you can clean up after the test ran.

\w is not a word boundary, it matches any word character, including underscores: [a-zA-Z0-9_]. \b is a word boundary, that is, it matches the position between a word and a non-alphanumeric character: \W or [^\w].

These implementations may vary from language to language though.

There are two approaches to this. Where possible I would start with a clean folder for your new git working directory and then copy your version of things in later. This might look something like*:

mv $dir $dir.orig
git clone $url $dir
rsync -av --delete --exclude '.git' $dir.orig/ $dir/
rm -rf $dir.orig

At this point you should have a pretty clean working copy with your previous working folder as the current working directory so any changes include file deletions will show up on the radar if you run git status.

On the other hand if you really must do it the other way around, you can get the same result with something like this:

cd $dir
git clone --no-checkout $url tempdir
mv tempdir/.git .
rmdir tempdir
git reset --mixed HEAD

Either way, the first thing I would do is run something like git stash to get a copy of all your local changes set aside, then you can re-apply them and work through which ones you want to get committed.

* _{Both examples assume you start out on the shell in the parent directory of your project.}

if(isset($_SESSION))
{}
else
{}

The easiest way is through keyword arguments:

class City():
  def __init__(self, city=None):
    pass

someCity = City(city="Berlin")

This is pretty basic stuff. Maybe look at the Python documentation?

In my limited experience with the following details.throws is a declaration that declares multiple exceptions that may occur but do not necessarily occur, throw is an action that can throw only one exception, typically a non-runtime exception, try catch is a block that catches exceptions that can be handled when an exception occurs in a method,this exception can be thrown.An exception can be understood as a responsibility that should be taken care of by the behavior that caused the exception, rather than by its upper callers. I hope my answer will help you

The smart thing is not to write the crypto yourself but to use something like passlib: https://bitbucket.org/ecollins/passlib/wiki/Home

It is easy to mess up writing your crypto code in a secure way. The nasty thing is that with non crypto code you often immediately notice it when it is not working since your program crashes. While with crypto code you often only find out after it is to late and your data has been compromised. Therefor I think it is better to use a package written by someone else who is knowledgable about the subject and which is based on battle tested protocols.

Also passlib has some nice features which make it easy to use and also easy to upgrade to a newer password hashing protocol if an old protocol turns out to be broken.

Also just a single round of sha512 is more vulnerable to dictionary attacks. sha512 is designed to be fast and this is actually a bad thing when trying to store passwords securely. Other people have thought long and hard about all this sort issues so you better take advantage of this.

I ran into similar problem a while back and what was happening in my case was the outer recycler view was working perfectly fine but the the adapter of inner/second recycler view had minor issues all the methods like constructor got initiated and even getCount() method was being called, although the final methods responsible to generate view ie..

1. onBindViewHolder() methods never got called. --> Problem 1.

2. When it got called finally it never show the list items/rows of recycler view. --> Problem 2.

Reason why this happened :: When you put a recycler view inside another recycler view, then height of the first/outer recycler view is not auto adjusted. It is defined when the first/outer view is created and then it remains fixed. At that point your second/inner recycler view has not yet loaded its items and thus its height is set as zero and never changes even when it gets data. Then when onBindViewHolder() in your second/inner recycler view is called, it gets items but it doesn't have the space to show them because its height is still zero. So the items in the second recycler view are never shown even when the onBindViewHolder() has added them to it.

Solution :: you have to create your custom LinearLayoutManager for the second recycler view and that is it. To create your own LinearLayoutManager: Create a Java class with the name CustomLinearLayoutManager and paste the code below into it. NO CHANGES REQUIRED

public class CustomLinearLayoutManager extends LinearLayoutManager {

    private static final String TAG = CustomLinearLayoutManager.class.getSimpleName();

    public CustomLinearLayoutManager(Context context) {
        super(context);

    }

    public CustomLinearLayoutManager(Context context, int orientation, boolean reverseLayout) {
        super(context, orientation, reverseLayout);
    }

Here is another suggestion. If you can prepend http:// to your url string you can do this

  string path = "http://www.example.com/aaa/bbb.jpg";
  Uri uri = new Uri(path);            
  string expectedString = 
      uri.PathAndQuery.Remove(uri.PathAndQuery.LastIndexOf("."));

You get the cursor position by calling GetCursorPos.

POINT p;
if (GetCursorPos(&p))
{
    //cursor position now in p.x and p.y
}

This returns the cursor position relative to screen coordinates. Call ScreenToClient to map to window coordinates.

if (ScreenToClient(hwnd, &p))
{
    //p.x and p.y are now relative to hwnd's client area
}

You hide and show the cursor with ShowCursor.

ShowCursor(FALSE);//hides the cursor
ShowCursor(TRUE);//shows it again

You must ensure that every call to hide the cursor is matched by one that shows it again.

You need to have the System.Linq namespace included in your view since Select is an extension method. You have a couple of options on how to do this:

Add @using System.Linq to the top of your cshtml file.

If you find that you will be using this namespace often in many of your views, you can do this for all views by modifying the web.config inside of your Views folder (not the one at the root). You should see a pages/namespace XML element, create a new add child that adds System.Linq. Here is an example:

<configuration>
    <system.web.webPages.razor>
        <pages>
            <namespaces>
                <add namespace="System.Linq" />
            </namespaces>
        </pages>
    </system.web.webPages.razor>
</configuration>

No, you do not need to check whether you’re already on the main thread. By dispatching the block to the main queue, you’re just scheduling the block to be executed serially on the main thread, which happens when the corresponding run loop is run.

If you already are on the main thread, the behaviour is the same: the block is scheduled, and executed when the run loop of the main thread is run.

It is not so easy to give out specific addresses to people say for a conference or a specific project or product. It could be more secure to prevent hacking such as SQL injection attacks etc.

Here is a jsfiddle example. Using Jquery to change the background color based on scroll pixel position.

Here is a fiddle using bootstrap

$(document).ready(function(){       
   var scroll_start = 0;
   var startchange = $('#startchange');
   var offset = startchange.offset();
    if (startchange.length){
   $(document).scroll(function() { 
      scroll_start = $(this).scrollTop();
      if(scroll_start > offset.top) {
          $(".navbar-default").css('background-color', '#f0f0f0');
       } else {
          $('.navbar-default').css('background-color', 'transparent');
       }
   });
    }
});

you can use angular's filter https://docs.angularjs.org/api/ng/filter/filter

in your controller:

$filter('filter')(myArray, {'id':73}) 

or in your HTML

{{ myArray | filter : {'id':73} }}

To fix the special character issue you just have to do 2 things

1.mysql_set_charset('utf8'); // set this line on top of your page in which you are using json.

2. If you are saving json data in database make sure that the particular column collation is set to "latin1_swedish_ci".

You can use JavaScript's encodeURIComponent:

encodeURIComponent('select * from table where i()')

giving

'select%20*%20from%20table%20where%20i()'

The DECLARE GLOBAL TEMPORARY TABLE statement defines a temporary table for the current connection.

These tables do not reside in the system catalogs and are not persistent.

Temporary tables exist only during the connection that declared them and cannot be referenced outside of that connection.

When the connection closes, the rows of the table are deleted, and the in-memory description of the temporary table is dropped.

For your reference http://docs.oracle.com/javadb/10.6.2.1/ref/rrefdeclaretemptable.html

Yes, you want to use tee:

tee - read from standard input and write to standard output and files

Just pipe your command to tee and pass the file as an argument, like so:

exec 1 | tee ${LOG_FILE}
exec 2 | tee ${LOG_FILE}

This both prints the output to the STDOUT and writes the same output to a log file. See man tee for more information.

Note that this won't write stderr to the log file, so if you want to combine the two streams then use:

exec 1 2>&1 | tee ${LOG_FILE}

This snippet works fine, for sending the Bearer Token using Jersey Client.

    WebTarget webTarget = client.target("endpoint");

    Invocation.Builder invocationBuilder =  webTarget.request(MediaType.APPLICATION_JSON);
    invocationBuilder.header("Authorization", "Bearer "+"Api Key");

    Response response = invocationBuilder.get();

    String responseData = response.readEntity(String.class);

    System.out.println(response.getStatus());
    System.out.println("responseData "+responseData);

Although a late reply, but I'm posting the answer because I suffered the same pain. I've created a new GitHub project just for that, as of now, it supports Bulk insert/update/delete for Sql server transparently using SqlBulkCopy.

https://github.com/MHanafy/EntityExtensions

There're other goodies as well, and hopefully, It will be extended to do more down the track.

Using it is as simple as

var insertsAndupdates = new List<object>();
var deletes = new List<object>();
context.BulkUpdate(insertsAndupdates, deletes);

Hope it helps!

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

In C and C++

unsigned = unsigned int (Integer type)
signed   = signed int (Integer type)

An unsigned integer containing n bits can have a value between 0 and (2^n-1) , which is 2^n different values.

An unsigned integer is either positive or zero.

Signed integers are stored in a computer using 2's complement.

I had the very same problem and then I realized that programming in NodeJS is actually different than Python or Java as its based on JavaScript. I'll try to use simple concepts as there may be a few new folks that would be interested or may come to this question.

Let's look at the following code :

var http = require('http'); // (1)
exports.handler = function(event, context) {
  console.log('start request to ' + event.url)
  http.get(event.url,  // (2)
  function(res) {  //(3)
    console.log("Got response: " + res.statusCode);
    context.succeed();
  }).on('error', function(e) {
    console.log("Got error: " + e.message);
    context.done(null, 'FAILURE');
  });

  console.log('end request to ' + event.url); //(4)
}

Whenever you make a call to a method in http package (1) , it is created as event and this event gets it separate event. The 'get' function (2) is actually the starting point of this separate event.

Now, the function at (3) will be executing in a separate event, and your code will continue it executing path and will straight jump to (4) and finish it off, because there is nothing more to do.

But the event fired at (2) is still executing somewhere and it will take its own sweet time to finish. Pretty bizarre, right ?. Well, No it is not. This is how NodeJS works and its pretty important you wrap your head around this concept. This is the place where JavaScript Promises come to help.

You can read more about JavaScript Promises here. In a nutshell, you would need a JavaScript Promise to keep the execution of code inline and will not spawn new / extra threads.

Most of the common NodeJS packages have a Promised version of their API available, but there are other approaches like BlueBirdJS that address the similar problem.

The code that you had written above can be loosely re-written as follows.

'use strict';
console.log('Loading function');
var rp = require('request-promise');
exports.handler = (event, context, callback) => {    

    var options = {
    uri: 'https://httpbin.org/ip',
    method: 'POST',
    body: {

    },
    json: true 
};


    rp(options).then(function (parsedBody) {
            console.log(parsedBody);
        })
        .catch(function (err) {
            // POST failed... 
            console.log(err);
        });

    context.done(null);
};

Please note that the above code will not work directly if you will import it in AWS Lambda. For Lambda, you will need to package the modules with the code base too.

Then just modify the previous answers to:

Console.Write(strToProcess.Replace("@", "@" + Environment.NewLine));

If you don't want the newlines in the text file, then don't preserve it.

Not sure if JSF provides a built-in functionality, but you could use java.sql.Date's constructor to convert to a date object: http://download.oracle.com/javase/1.5.0/docs/api/java/sql/Date.html#Date(long)

Then you should be able to use higher level features provided by Java SE, Java EE to display and format the extracted date. You could instantiate a java.util.Calendar and explicitly set the time: http://download.oracle.com/javase/1.5.0/docs/api/java/util/Calendar.html#setTime(java.util.Date)

EDIT: The JSF components should not take care of the conversion. Your data access layer (persistence layer) should take care of this. In other words, your JSF components should not handle the long typed attributes but only a Date or Calendar typed attributes.

you could also use the builtin "join" filter (http://jinja.pocoo.org/docs/templates/#join like this:

{{ users|join(', ') }}

Switch to Theme... is also an option

public static int getDifferenceIndays(long timestamp1, long timestamp2) {
    final int SECONDS = 60;
    final int MINUTES = 60;
    final int HOURS = 24;
    final int MILLIES = 1000;
    long temp;
    if (timestamp1 < timestamp2) {
        temp = timestamp1;
        timestamp1 = timestamp2;
        timestamp2 = temp;
    }
    Calendar startDate = Calendar.getInstance(TimeZone.getDefault());
    Calendar endDate = Calendar.getInstance(TimeZone.getDefault());
    endDate.setTimeInMillis(timestamp1);
    startDate.setTimeInMillis(timestamp2);
    if ((timestamp1 - timestamp2) < 1 * HOURS * MINUTES * SECONDS * MILLIES) {
        int day1 = endDate.get(Calendar.DAY_OF_MONTH);
        int day2 = startDate.get(Calendar.DAY_OF_MONTH);
        if (day1 == day2) {
            return 0;
        } else {
            return 1;
        }
    }
    int diffDays = 0;
    startDate.add(Calendar.DAY_OF_MONTH, diffDays);
    while (startDate.before(endDate)) {
        startDate.add(Calendar.DAY_OF_MONTH, 1);
        diffDays++;
    }
    return diffDays;
}

The simplest solution is to apply Python str function to the column you are trying to loop through.

If you are using pandas, this can be implemented as:

dataframe['column_name']=dataframe['column_name'].apply(str)

Following code worked for me:

     git fetch
     git checkout <branch from which file needs to be fetched> <filepath> 

I think you are creating a document that looks like this:

<mycatch>
    ....
</mycatch>
<mycatch>
    ....
</mycatch>

This is not a valid XML document as it has more than one root element. You must have a single top-level element, as in

<mydocument>      
  <mycatch>
      ....
  </mycatch>
  <mycatch>
      ....
  </mycatch>
  ....
</mydocument>

Check whether a String contains at least one white space character:

public static boolean containsWhiteSpace(final String testCode){
    if(testCode != null){
        for(int i = 0; i < testCode.length(); i++){
            if(Character.isWhitespace(testCode.charAt(i))){
                return true;
            }
        }
    }
    return false;
}

Reference:

• Character.isWhitespace(char)

Using the Guava library, it's much simpler:

return CharMatcher.WHITESPACE.matchesAnyOf(testCode);

CharMatcher.WHITESPACE is also a lot more thorough when it comes to Unicode support.

Eclipse Indigo + M2Eclipse 1.0 makes it very easy.

If you don't already have the Git connector for M2Eclipse install it. M2Eclipse will help you along by prompting you on the Import menu.

1. Select the "Import..." context menu from the Package Explorer view
2. Select "Check out Maven projects from SCM" option under the Maven category
3. On the window that is presented choose the link "Find more SCM connectors in the m2e Marketplace
4. Find connector for Git...install...restart

Note that in the search box you may have to enter "EGit" instead of "Git" to find the right connector.

With that done, simply go to the EGit repository, bring up the context menu for the Working directory and select "Import Maven projects...".

Done!

You can use jquery.chosen or bootstrap-select to add style to your buttons.Both work great. Caveat for Using Chosen or bootstrap-select: they both hide the original select and add in their own div with its own ID. If you are using jquery.validate along with this, for instance, it wont find the original select to do its validation on because it has been renamed.

Because you are creatin a table expression, you have to specify the structure of that table, you can achive this on two way:

1: In the select you can use the original columnnames (as in your first example), but with aggregates you have to use an alias (also in conflicting names). Like

sum(totalitems) as bkdqty

2: You need to specify the column names rigth after the name of the talbe, and then you just have to take care that the count of the names should mach the number of coulms was selected in the query. Like:

d (duration, bkdqty) 
AS (Select.... ) 

With the second solution both of your query will work!

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

Try this. It is not watertight¹, but it might be good enough:

function addhttp($url) {
    if (!preg_match("@^[hf]tt?ps?://@", $url)) {
        $url = "http://" . $url;
    }
    return $url;
}

_{1. That is, prefixes like "fttps://" are treated as valid.}

Step 1 Create Your CSV file

Step 2 log in to your mysql server

     mysql -uroot -pyourpassword 

Step 3 load your csv file

     load data local infile '//home/my-sys/my-excel.csv' into table my_tables fields terminated by ',' enclosed by '"' (Country, Amount,Qty);

PHP (typically) generates HTML output for a web-site.

When displaying HTML, the browser (typically) collapses all whitespace in text into a single space. Sometimes, between tags, it even collapses whitespace to nothing.

In order to persuade the browser to display whitespace, you need to include special tags like   or <br/> in your HTML to add non-breaking whitespace or new lines, respectively.

A Python variable stores an untyped reference to the target object that represent the value.

Any assignment operation means assigning the untyped reference to the assigned object -- i.e. the object is shared via the original and the new (counted) references.

The value type is bound to the target object, not to the reference value. The (strong) type checking is done when an operation with the value is performed (run time).

In other words, variables (technically) have no type -- it does not make sense to think in terms of a variable type if one wants to be exact. But references are automatically dereferenced and we actually think in terms of the type of the target object.

Using Collections#addAll()

String[] words = {"ace","boom","crew","dog","eon"};
List<String> arrayList = new ArrayList<>(); 
Collections.addAll(arrayList, words); 

Previous answer is not good for negative numbers. Use a short type instead of int

        short iValue = -1400;
        string sResult = iValue.ToString("X2");
        Console.WriteLine("Value={0} Result={1}", iValue, sResult);

Now result is FA88

You can add either -DskipTests or -Dmaven.test.skip=true to any mvn command for skipping tests. In your case it would be like below:

mvn package -DskipTests

OR

mvn package -Dmaven.test.skip=true

You dont need to define option tags, you can do this using the ngOptions directive: https://docs.angularjs.org/api/ng/directive/ngOptions

<select class="form-control" ng-change="unitChanged()" ng-model="data.unit" ng-options="unit.id as unit.label for unit in units"></select>

The errors actually vary. It's helpful to run ./emulator with -verbose option, as it will show the actual errors.

I use mostly 978px width for my designs. Adv. of 978px : can be divided by 2,3.

Leaving the catch block empty should do the trick. This is almost always a bad idea, though. On one hand, there's a performance penalty, and on the other (and this is more important), you always want to know when there's an error.

I would guess that the "callee" function failing, in your case, is actually not necessarily an "error," so to speak. That is, it is expected for it to fail sometimes. If this is the case, there is almost always a better way to handle it than using exceptions.

There are, if you'll pardon the pun, exceptions to the "rule", though. For example, if function2 were to call a web service whose results aren't really necessary for your page, this kind of pattern might be ok. Although, in almost 100% of cases, you should at least be logging it somewhere. In this scenario I'd log it in a finally block and report whether or not the service returned. Remember that data like that which may not be valuable to you now can become valuable later!

Last edit (probably):

In a comment I suggested you put the try/catch inside function2. Just thought I would elaborate. Function2 would look like this:

public Something? function2()
{
    try
    {
        //all of your function goes here
        return anActualObjectOfTypeSomething;
    }
    catch(Exception ex)
    {
        //logging goes here
        return null;
    }
}

That way, since you use a nullable return type, returning null doesn't hurt you.

SHA1 is a cryptographic hash function, so the intention of the design was to avoid what you are trying to do.

However, breaking a SHA1 hash is technically possible. You can do so by just trying to guess what was hashed. This brute-force approach is of course not efficient, but that's pretty much the only way.

So to answer your question: yes, it is possible, but you need significant computing power. Some researchers estimate that it costs $70k - $120k.

As far as we can tell today, there is also no other way but to guess the hashed input. This is because operations such as mod eliminate information from your input. Suppose you calculate mod 5 and you get 0. What was the input? Was it 0, 5 or 500? You see, you can't really 'go back' in this case.

You might want to try this example for version 2.6 of Python.

def my_print(text, begin, end):
    "Print text in UPPER between 'begin' and 'end' in lower."
    for obj in (text, begin, end):
        assert isinstance(obj, str), 'Argument of wrong type!'
    print begin.lower() + text.upper() + end.lower()

However, have you considered letting the function fail naturally instead?

or shorter

function sortBy(field) {_x000D_
  return function(a, b) {_x000D_
    return (a[field] > b[field]) - (a[field] < b[field])_x000D_
  };_x000D_
}_x000D_
_x000D_
let myArray = [_x000D_
    {tabid: 6237, url: 'https://reddit.com/r/znation'},_x000D_
    {tabid: 8430, url: 'https://reddit.com/r/soccer'},_x000D_
    {tabid: 1400, url: 'https://reddit.com/r/askreddit'},_x000D_
    {tabid: 3620, url: 'https://reddit.com/r/tacobell'},_x000D_
    {tabid: 5753, url: 'https://reddit.com/r/reddevils'},_x000D_
]_x000D_
_x000D_
myArray.sort(sortBy('url'));_x000D_
console.log(myArray);

I use:

var value = "'Field1','Field2','Field3'".Replace("'", "\""); 

as opposed to the equivalent

var value = "\"Field1\",\"Field2\",\"Field3\"";

Because the former has far less noise than the latter, making it easier to see typo's etc.

I use it a lot in unit tests.

class func uuid(completionHandler: @escaping (String) -> ()) {
    if let uuid = UIDevice.current.identifierForVendor?.uuidString {
        completionHandler(uuid)
    }
    else {
        // If the value is nil, wait and get the value again later. This happens, for example, after the device has been restarted but before the user has unlocked the device.
        // https://developer.apple.com/documentation/uikit/uidevice/1620059-identifierforvendor?language=objc
        DispatchQueue.main.asyncAfter(deadline: .now() + 1.0) {
            uuid(completionHandler: completionHandler)
        }
    }
}

If you are looking to copy all the text files in one folder to merge and copy to another folder, you can do this to achieve that:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.IO;

namespace HowToCopyTextFiles
{
  class Program
  {
    static void Main(string[] args)
    {
      string mydocpath=Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments);     
      StringBuilder sb = new StringBuilder();
      foreach (string txtName in Directory.GetFiles(@"D:\Links","*.txt"))
      {
        using (StreamReader sr = new StreamReader(txtName))
        {
          sb.AppendLine(txtName.ToString());
          sb.AppendLine("= = = = = =");
          sb.Append(sr.ReadToEnd());
          sb.AppendLine();
          sb.AppendLine();   
        }
      }
      using (StreamWriter outfile=new StreamWriter(mydocpath + @"\AllTxtFiles.txt"))
      {    
        outfile.Write(sb.ToString());
      }   
    }
  }
}

Number of a columns in the result set you can get with code (as DB is used PostgreSQL):

//load the driver for PostgreSQL
Class.forName("org.postgresql.Driver");

String url = "jdbc:postgresql://localhost/test";
Properties props = new Properties();
props.setProperty("user","mydbuser");
props.setProperty("password","mydbpass");
Connection conn = DriverManager.getConnection(url, props);

//create statement
Statement stat = conn.createStatement();

//obtain a result set
ResultSet rs = stat.executeQuery("SELECT c1, c2, c3, c4, c5 FROM MY_TABLE");

//from result set give metadata
ResultSetMetaData rsmd = rs.getMetaData();

//columns count from metadata object
int numOfCols = rsmd.getColumnCount();

But you can get more meta-informations about columns:

for(int i = 1; i <= numOfCols; i++)
{
    System.out.println(rsmd.getColumnName(i));
}

And at least but not least, you can get some info not just about table but about DB too, how to do it you can find here and here.

final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.hide(currentFragment);
ft.add(R.id.content_frame, newFragment.newInstance(context), "Profile");
ft.addToBackStack(null);
ft.commit();

Here is a good example -

ul li{

The simplest way you can do is:

#include <stdlib.h>

system("Color F3");

Where "F" is the code for the background color and 3 is the code for the text color.

Mess around with it to see other color combinations:

system("Color 1A");
std::cout << "Hello, what is your name?" << std::endl;
system("Color 3B");
std::cout << "Hello, what is your name?" << std::endl;
system("Color 4c");
std::cout << "Hello, what is your name?" << std::endl;

Note: I only tested on Windows. Works. As pointed out, this is not cross-platform, it will not work on Linux systems.

There are lots of solutions:

b = Arrays.copyOf(a, a.length);

Which allocates a new array, copies over the elements of a, and returns the new array.

Or

b = new int[a.length];
System.arraycopy(a, 0, b, 0, b.length);

Which copies the source array content into a destination array that you allocate yourself.

Or

b = a.clone();

which works very much like Arrays.copyOf(). See this thread.

Or the one you posted, if you reverse the direction of the assignment in the loop:

b[i] = a[i]; // NOT a[i] = b[i];

I'm using Laravel Lumen to build a small application.
For me it was because I didn't had the DB_USERNAME defined in my .env file.

Setting this solved my problem.

You could start by reading the documentation for Date. Then you realize that Date’s methods are all deprecated and turn to Calender instead.

Calendar now = Calendar.getInstance();
System.out.println(now.get(Calendar.DAY_OF_MONTH));

simple / elegant / how I do it:

Preview:

XML:

<Spinner
    android:id="@+id/spinner1"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:background="@android:drawable/btn_dropdown"
    android:spinnerMode="dropdown"/>

spinnerMode set to dropdown is androids way to make a dropdown. (https://developer.android.com/reference/android/widget/Spinner#attr_android:spinnerMode)

Java:

//get the spinner from the xml.
Spinner dropdown = findViewById(R.id.spinner1);
//create a list of items for the spinner.
String[] items = new String[]{"1", "2", "three"};
//create an adapter to describe how the items are displayed, adapters are used in several places in android.
//There are multiple variations of this, but this is the basic variant.
ArrayAdapter<String> adapter = new ArrayAdapter<>(this, android.R.layout.simple_spinner_dropdown_item, items);
//set the spinners adapter to the previously created one.
dropdown.setAdapter(adapter);

This is the basics but there is more to be self taught with experimentation. https://developer.android.com/guide/topics/ui/controls/spinner.html

Recommend you use FREQUENCY rather than using COUNTIF.

In your front sheet; enter 01/04/2014 into E5, 01/05/2014 into E6 etc.

Select the range of adjacent cells you want to populate. Enter:

=FREQUENCY(2013!!$A$2:$A$50,'2013 Metrics'!E5:EN)

(where N is the final row reference in your range)

Here is the complete code for REST API requests using NSURLSession in swift

For GET Request

 let configuration = NSURLSessionConfiguration .defaultSessionConfiguration()
    let session = NSURLSession(configuration: configuration)


    let urlString = NSString(format: "your URL here")

    print("get wallet balance url string is \(urlString)")
    //let url = NSURL(string: urlString as String)
    let request : NSMutableURLRequest = NSMutableURLRequest()
    request.URL = NSURL(string: NSString(format: "%@", urlString) as String)
    request.HTTPMethod = "GET"
    request.timeoutInterval = 30

    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")

    let dataTask = session.dataTaskWithRequest(request) {
        (let data: NSData?, let response: NSURLResponse?, let error: NSError?) -> Void in

        // 1: Check HTTP Response for successful GET request
        guard let httpResponse = response as? NSHTTPURLResponse, receivedData = data
            else {
                print("error: not a valid http response")
                return
        }

        switch (httpResponse.statusCode)
        {
        case 200:

            let response = NSString (data: receivedData, encoding: NSUTF8StringEncoding)
            print("response is \(response)")


            do {
                let getResponse = try NSJSONSerialization.JSONObjectWithData(receivedData, options: .AllowFragments)

                EZLoadingActivity .hide()

               // }
            } catch {
                print("error serializing JSON: \(error)")
            }

            break
        case 400:

            break
        default:
            print("wallet GET request got response \(httpResponse.statusCode)")
        }
    }
    dataTask.resume()

For POST request ...

let configuration = NSURLSessionConfiguration .defaultSessionConfiguration()
    let session = NSURLSession(configuration: configuration)

    let params = ["username":bindings .objectForKey("username"), "provider":"walkingcoin", "securityQuestion":securityQuestionField.text!, "securityAnswer":securityAnswerField.text!] as Dictionary<String, AnyObject>

    let urlString = NSString(format: “your URL”);
    print("url string is \(urlString)")
    let request : NSMutableURLRequest = NSMutableURLRequest()
    request.URL = NSURL(string: NSString(format: "%@", urlString)as String)
    request.HTTPMethod = "POST"
    request.timeoutInterval = 30
    request.addValue("application/json", forHTTPHeaderField: "Content-Type")
    request.addValue("application/json", forHTTPHeaderField: "Accept")      
    request.HTTPBody  = try! NSJSONSerialization.dataWithJSONObject(params, options: [])

    let dataTask = session.dataTaskWithRequest(request)
        {
            (let data: NSData?, let response: NSURLResponse?, let error: NSError?) -> Void in
            // 1: Check HTTP Response for successful GET request
            guard let httpResponse = response as? NSHTTPURLResponse, receivedData = data
                else {
                    print("error: not a valid http response")
                    return
            }

            switch (httpResponse.statusCode)
            {
            case 200:

                let response = NSString (data: receivedData, encoding: NSUTF8StringEncoding)


                if response == "SUCCESS"
                {

                }

            default:
                print("save profile POST request got response \(httpResponse.statusCode)")
            }
    }
    dataTask.resume()

I hope it works.

In the provided example your decimal is 8.6. Had it been 8.5 or 9.5, the statement i1 == i2 might have been true. Infact it would have been true for 8.5, and false for 9.5.

Explanation:

Regardless of the decimal part, the second statement, int i2 = (int)score will discard the decimal part and simply return you the integer part. Quite dangerous thing to do, as data loss might occur.

Now, for the first statement, two things can happen. If the decimal part is 5, that is, it is half way through, a decision is to be made. Do we round up or down? In C#, the Convert class implements banker's rounding. See this answer for deeper explanation. Simply put, if the number is even, round down, if the number is odd, round up.

E.g. Consider:

        double score = 8.5;
        int i1 = Convert.ToInt32(score); // 8
        int i2 = (int)score;             // 8

        score += 1;
        i1 = Convert.ToInt32(score);     // 10
        i2 = (int)score;                 // 9

one of the other tool (besides file) you can use is xdg-mime

eg xdg-mime query filetype <file>

if you have yum,

yum install xdg-utils.noarch

An example comparison of xdg-mime and file on a Subrip(subtitles) file

$ xdg-mime query filetype subtitles.srt
application/x-subrip

$ file --mime-type subtitles.srt
subtitles.srt: text/plain

in the above file only show it as plain text.

It's probably worth noting that Groovy has this feature:

import java.util.Calendar
import com.example.Calendar as MyCalendar

MyCalendar myCalendar = new MyCalendar()

The opposite of :hover appears to be :link.

(edit: not technically an opposite because there are 4 selectors :link, :visited, :hover and :active. Five if you include :focus.)

For example when defining a rule .button:hover{ text-decoration:none } to remove the underline on a button, the underline shows up when you roll off the button in some browsers. I've fixed this with .button:hover, .button:link{ text-decoration:none }

This of course only works for elements that are actually links (have href attribute)

Unfortunately (unless I'm mistaken), I think you need to iterate over the results object.

for(var i = 0; i < results.length; i += 1){
    var result = results[i];
    if(result.id === id){
        return result;
    }
}

At least this way it will break out of the iteration as soon as it finds the correct matching id.

Swift Version

The easiest method is to set the tableFooterView property:

override func viewDidLoad() {
    super.viewDidLoad()
    // This will remove extra separators from tableview
    self.tableView.tableFooterView = UIView(frame: CGRectZero)
}

I have Had the same issue and the only Solution i found was open Package manager> Select Microsoft and .Net as Package Source and You will install it..

When I deal with this problem in other languages I go for a separation of code and HTML. Something like:

1.) Create a HTML template. use [varname] placeholders to mark replaced/inserted content.
2.) Fill your template variables from an array or structure/mapping/dictionary

Write( FillTemplate(myHTMLTemplate, myVariables) ) # pseudo-code

function areThereDuplicates(args) {

    let count = {};
    for(let i = 0; i < args.length; i++){
         count[args[i]] = 1 + (count[args[i]] || 0);
    }
    let found = Object.keys(count).filter(function(key) {
        return count[key] > 1;
    });

Why not keep things simple and use an adjacency matrix or an adjacency list?

It was changing the line endings (from Windows CRLF to Unix LF) in the .htaccess file that fixed it for me.

You can also use the ignore syntax instead of using (or better the 'as any') notation:

// @ts-ignore
$("div.printArea").printArea();

Yup, BOOL is a typedef for a signed char according to objc.h.

I don't know about bool, though. That's a C++ thing, right? If it's defined as a signed char where 1 is YES/true and 0 is NO/false, then I imagine it doesn't matter which one you use.

Since BOOL is part of Objective-C, though, it probably makes more sense to use a BOOL for clarity (other Objective-C developers might be puzzled if they see a bool in use).

Update version

Objective-C

Create:

NSDictionary *dictionary = @{@"myKey1": @7, @"myKey2": @5}; 

Change:

NSMutableDictionary *mutableDictionary = [dictionary mutableCopy];     //Make the dictionary mutable to change/add
mutableDictionary[@"myKey3"] = @3;

The short-hand syntax is called Objective-C Literals.

Swift

Create:

var dictionary = ["myKey1": 7, "myKey2": 5]

Change:

dictionary["myKey3"] = 3

You could use the title attribute in html :)

<label title="This is the full title of the label">This is the...</label>

When you keep the mouse over for a brief moment, it should pop up with a box, containing the full title.

If you want more control, I suggest you look into the Tipsy Plugin for jQuery - It can be found at http://onehackoranother.com/projects/jquery/tipsy/ and is fairly simple to get started with.

This is best done using an extension to the existing NSDate class.

The following extension adds a new initializer which will create a date in the current locale using the date string in the format you specified.

extension NSDate
{
    convenience
      init(dateString:String) {
      let dateStringFormatter = NSDateFormatter()
      dateStringFormatter.dateFormat = "yyyy-MM-dd"
      dateStringFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX")
      let d = dateStringFormatter.dateFromString(dateString)!
      self.init(timeInterval:0, sinceDate:d)
    }
 }

Now you can create an NSDate from Swift just by doing:

NSDate(dateString:"2014-06-06")

Please note that this implementation does not cache the NSDateFormatter, which you might want to do for performance reasons if you expect to be creating many NSDates in this way.

Please also note that this implementation will simply crash if you try to initialize an NSDate by passing in a string that cannot be parsed correctly. This is because of the forced unwrap of the optional value returned by dateFromString. If you wanted to return a nil on bad parses, you would ideally use a failible initializer; but you cannot do that now (June 2015), because of a limitation in Swift 1.2, so then you're next best choice is to use a class factory method.

A more elaborate example, which addresses both issues, is here: https://gist.github.com/algal/09b08515460b7bd229fa .

Update for Swift 5

extension Date {
    init(_ dateString:String) {
        let dateStringFormatter = DateFormatter()
        dateStringFormatter.dateFormat = "yyyy-MM-dd"
        dateStringFormatter.locale = NSLocale(localeIdentifier: "en_US_POSIX") as Locale
        let date = dateStringFormatter.date(from: dateString)!
        self.init(timeInterval:0, since:date)
    }
}

Add following attribute to the element you want to have dotted line.

style="border-bottom: 1px dotted #ff0000;"

Yep: Use the outline property; it acts as a second border outside of your border. Beware, tho', it can interact in a wonky fashion with margins, paddings and drop-shadows. In some browsers you might have to use a browser-specific prefix as well; in order to make sure it picks up on it: -webkit-outline and the like (although WebKit in particular doesn't require this).

This can also be useful in the case where you want to jettison the outline for certain browsers (such as is the case if you want to combine the outline with a drop shadow; in WebKit the outline is inside of the shadow; in FireFox it is outside, so -moz-outline: 0 is useful to ensure that you don't get a gnarly line around your beautiful CSS drop shadow).

.someclass {
  border: 1px solid blue;
  outline: 1px solid darkblue;
}

Edit: Some people have remarked that outline doesn't jive well with IE < 8. While this is true; supporting IE < 8 really isn't something you should be doing.

Unless you're worried about performance, use string streams:

#include <sstream>
//..

std::ostringstream ss;
ss << myFloat;
std::string s(ss.str());

If you're okay with Boost, lexical_cast<> is a convenient alternative:

std::string s = boost::lexical_cast<std::string>(myFloat);

Efficient alternatives are e.g. FastFormat or simply the C-style functions.

One solution to this would be a list comprehension, with pattern matching inside your tuple:

>>> mylist = [(25,7),(26,9),(55,10)]
>>> [age for (age,person_id) in mylist if person_id == 10]
[55]

Another way would be using map and filter:

>>> map( lambda (age,_): age, filter( lambda (_,person_id): person_id == 10, mylist) )
[55]

You need to unicode each element of the list individually

[x.encode('utf-8') for x in tmp]

I would go for it.next() for the simple reason that next() is guaranteed to be implemented, while remove() is an optional operation.

E next()

Returns the next element in the iteration.

void remove()

Removes from the underlying collection the last element returned by the iterator (optional operation).

I think, from your description, the following would suffice:

DELETE FROM guide_category 
WHERE id_guide NOT IN (SELECT id_guide FROM guide)

I assume, that there are no referential integrity constraints on the tables involved, are there?

Instead, just do a hook_form_alter and make the button an image button and you are done!

In order to delete all images, use the given command

docker rmi $(docker images -q)

In order to delete all containers, use the given command

I use this handy function:

By downloading it with a 4094 byte step it will not full your memory

function download($file_source, $file_target) {
    $rh = fopen($file_source, 'rb');
    $wh = fopen($file_target, 'w+b');
    if (!$rh || !$wh) {
        return false;
    }

    while (!feof($rh)) {
        if (fwrite($wh, fread($rh, 4096)) === FALSE) {
            return false;
        }
        echo ' ';
        flush();
    }

    fclose($rh);
    fclose($wh);

    return true;
}

Usage:

     $result = download('http://url','path/local/file');

You can then check if everything is ok with:

     if (!$result)
         throw new Exception('Download error...');

KeyPress event is invoked only for character (printable) keys, KeyDown event is raised for all including nonprintable such as Control, Shift, Alt, BackSpace, etc.

UPDATE:

The keypress event is fired when a key is pressed down and that key normally produces a character value

Reference.

What’s the difference between compiled and interpreted language?

The difference is not in the language; it is in the implementation.

Having got that out of my system, here's an answer:

• In a compiled implementation, the original program is translated into native machine instructions, which are executed directly by the hardware.

• In an interpreted implementation, the original program is translated into something else. Another program, called "the interpreter", then examines "something else" and performs whatever actions are called for. Depending on the language and its implementation, there are a variety of forms of "something else". From more popular to less popular, "something else" might be

  • Binary instructions for a virtual machine, often called bytecode, as is done in Lua, Python, Ruby, Smalltalk, and many other systems (the approach was popularized in the 1970s by the UCSD P-system and UCSD Pascal)

  • A tree-like representation of the original program, such as an abstract-syntax tree, as is done for many prototype or educational interpreters

  • A tokenized representation of the source program, similar to Tcl

  • The characters of the source program, as was done in MINT and TRAC

One thing that complicates the issue is that it is possible to translate (compile) bytecode into native machine instructions. Thus, a successful intepreted implementation might eventually acquire a compiler. If the compiler runs dynamically, behind the scenes, it is often called a just-in-time compiler or JIT compiler. JITs have been developed for Java, JavaScript, Lua, and I daresay many other languages. At that point you can have a hybrid implementation in which some code is interpreted and some code is compiled.

The problem obviously was (as you figured it out) that port 36250 wasn't open on the server side at the time you tried to connect (hence connection refused). I can see the server was supposed to open this socket after receiving SEND command on another connection, but it apparently was "not opening [it] up in sync with the client side".

Well, the main reason would be there was no synchronisation whatsoever. Calling:

cs.send("SEND " + FILE)
cs.close()

would just place the data into a OS buffer; close would probably flush the data and push into the network, but it would almost certainly return before the data would reach the server. Adding sleep after close might mitigate the problem, but this is not synchronisation.

The correct solution would be to make sure the server has opened the connection. This would require server sending you some message back (for example OK, or better PORT 36250 to indicate where to connect). This would make sure the server is already listening.

The other thing is you must check the return values of send to make sure how many bytes was taken from your buffer. Or use sendall.

(Sorry for disturbing with this late answer, but I found this to be a high traffic question and I really didn't like the sleep idea in the comments section.)

$("button").click(function() {
    alert(this.id);
});

You want to use sections when you want a bit of code/content to render in a placeholder that has been defined in a layout page.

In the specific example you linked, he has defined the RenderSection in the _Layout.cshtml. Any view that uses that layout can define an @section of the same name as defined in Layout, and it will replace the RenderSection call in the layout.

Perhaps you're wondering how we know Index.cshtml uses that layout? This is due to a bit of MVC/Razor convention. If you look at the dialog where he is adding the view, the box "Use layout or master page" is checked, and just below that it says "Leave empty if it is set in a Razor _viewstart file". It isn't shown, but inside that _ViewStart.cshtml file is code like:

@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}

The way viewstarts work is that any cshtml file within the same directory or child directories will run the ViewStart before it runs itself.

Which is what tells us that Index.cshtml uses Shared/_Layout.cshtml.

There are some misconceptions here.

Frequencies above 500 can be represented in an FFT result of length 1000. Unfortunately these frequencies are all folded together and mixed into the first 500 FFT result bins. So normally you don't want to feed an FFT a signal containing any frequencies at or above half the sampling rate, as the FFT won't care and will just mix the high frequencies together with the low ones (aliasing) making the result pretty much useless. That's why data should be low-pass filtered before being sampled and fed to an FFT.

The FFT returns amplitudes without frequencies because the frequencies depend, not just on the length of the FFT, but also on the sample rate of the data, which isn't part of the FFT itself or it's input. You can feed the same length FFT data at any sample rate, as thus get any range of frequencies out of it.

The reason the result plots ends at 500 is that, for any real data input, the frequencies above half the length of the FFT are just mirrored repeats (complex conjugated) of the data in the first half. Since they are duplicates, most people just ignore them. Why plot duplicates? The FFT calculates the other half of the result for people who feed the FFT complex data (with both real and imaginary components), which does create two different halves.

One way to achieve this is

>>> pd.DataFrame(np.array([[2, 3, 4]]), columns=['A', 'B', 'C']).append(df, ignore_index=True)
Out[330]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

Generally, it's easiest to append dataframes, not series. In your case, since you want the new row to be "on top" (with starting id), and there is no function pd.prepend(), I first create the new dataframe and then append your old one.

ignore_index will ignore the old ongoing index in your dataframe and ensure that the first row actually starts with index 1 instead of restarting with index 0.

Typical Disclaimer: Cetero censeo ... appending rows is a quite inefficient operation. If you care about performance and can somehow ensure to first create a dataframe with the correct (longer) index and then just inserting the additional row into the dataframe, you should definitely do that. See:

>>> index = np.array([0, 1, 2])
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[0:1] = [list(s1), list(s2)]
>>> df2
Out[336]: 
     A    B    C
0    5    6    7
1    7    8    9
2  NaN  NaN  NaN
>>> df2 = pd.DataFrame(columns=['A', 'B', 'C'], index=index)
>>> df2.loc[1:] = [list(s1), list(s2)]

So far, we have what you had as df:

>>> df2
Out[339]: 
     A    B    C
0  NaN  NaN  NaN
1    5    6    7
2    7    8    9

But now you can easily insert the row as follows. Since the space was preallocated, this is more efficient.

>>> df2.loc[0] = np.array([2, 3, 4])
>>> df2
Out[341]: 
   A  B  C
0  2  3  4
1  5  6  7
2  7  8  9

Here is an example of accessing the ith index of a std::vector using an std::iterator within a loop which does not require incrementing two iterators.

std::vector<std::string> strs = {"sigma" "alpha", "beta", "rho", "nova"};
int nth = 2;
std::vector<std::string>::iterator it;
for(it = strs.begin(); it != strs.end(); it++) {
    int ith = it - strs.begin();
    if(ith == nth) {
        printf("Iterator within  a for-loop: strs[%d] = %s\n", ith, (*it).c_str());
    }
}

Without a for-loop

it = strs.begin() + nth;
printf("Iterator without a for-loop: strs[%d] = %s\n", nth, (*it).c_str());

and using at method:

printf("Using at position: strs[%d] = %s\n", nth, strs.at(nth).c_str());

As RocketDonkey suggested, your module itself needs to have some docstrings.

For example, in myModule/__init__.py:

"""
The mod module
"""

You'd also want to generate documentation for each file in myModule/*.py using

pydoc myModule.thefilename

to make sure the generated files match the ones that are referenced from the main module documentation file.

If the table has an ID:

const tableObject = document.getElementById(tableId);
const rowCount = tableObject[1].childElementCount;

If the table has a Class:

const tableObject = document.getElementsByClassName(tableClass);
const rowCount = tableObject[1].childElementCount;

If the table has a Name:

const tableObject = document.getElementsByTagName('table');
const rowCount = tableObject[1].childElementCount;

Note: index 1 represents <tbody> tag

If you use %pylab inline you can (on a new line) insert the following command:

%pylab inline
pylab.rcParams['figure.figsize'] = (10, 6)

This will set all figures in your document (unless otherwise specified) to be of the size (10, 6), where the first entry is the width and the second is the height.

See this SO post for more details. https://stackoverflow.com/a/17231361/1419668

Did you move the directory out from under your shell? This can happen if you restored your project from a backup. To fix this, just cd out and back in:

cd ../
cd -

Try this

function arraysEqual(arr1, arr2){
    if (!Array.isArray(arr1) || !Array.isArray(arr2) || arr1.length!=arr2.length)
        return false;

    return arr1.length==arr1.filter(word => arr2.includes(word)).length;
}

All the current answers clobber the non-writing permissions: they make the file readable-but-not-executable for everybody. Granted, this is because the initial question asked for 444 permissions -- but we can do better!

Here's a solution that leaves all the individual "read" and "execute" bits untouched. I wrote verbose code to make it easy to understand; you can make it more terse if you like.

import os
import stat

def remove_write_permissions(path):
    """Remove write permissions from this path, while keeping all other permissions intact.

    Params:
        path:  The path whose permissions to alter.
    """
    NO_USER_WRITING = ~stat.S_IWUSR
    NO_GROUP_WRITING = ~stat.S_IWGRP
    NO_OTHER_WRITING = ~stat.S_IWOTH
    NO_WRITING = NO_USER_WRITING & NO_GROUP_WRITING & NO_OTHER_WRITING

    current_permissions = stat.S_IMODE(os.lstat(path).st_mode)
    os.chmod(path, current_permissions & NO_WRITING)

Why does this work?

As John La Rooy pointed out,stat.S_IWUSR basically means "the bitmask for the user's write permissions". We want to set the corresponding permission bit to 0. To do that, we need the exact opposite bitmask (i.e., one with a 0 in that location, and 1's everywhere else). The ~ operator, which flips all the bits, gives us exactly that. If we apply this to any variable via the "bitwise and" operator (&), it will zero out the corresponding bit.

We need to repeat this logic with the "group" and "other" permission bits, too. Here we can save some time by just &'ing them all together (forming the NO_WRITING bit constant).

The last step is to get the current file's permissions, and actually perform the bitwise-and operation.

You may have accidentally cloned the repository in https instead of ssh. I've made this mistake numerous times on github. Make sure that you copy the ssh link in the first place when cloning, instead of the https link.

From Bootstrap's docs about the remote option;

This option is deprecated since v3.3.0 and has been removed in v4. We recommend instead using client-side templating or a data binding framework, or calling jQuery.load yourself.

If a remote URL is provided, content will be loaded one time via jQuery's load method and injected into the .modal-content div. If you're using the data-api, you may alternatively use the href attribute to specify the remote source. An example of this is shown below:

<a data-toggle="modal" href="remote.html" data-target="#modal">Click me</a>

That's the .modal-content div, not .modal-body. If you want to put content inside .modal-body then you need to do that with custom javascript.

So I would call jQuery.load programmatically, meaning you can keep the functionality of the dismiss and/or other buttons as required.

To do this you could use a data tag with the URL from the button that opens the modal, and use the show.bs.modal event to load content into the .modal-body div.

HTML Link/Button

<a href="#" data-toggle="modal" data-load-url="remote.html" data-target="#myModal">Click me</a>

jQuery

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = $(e.relatedTarget).data('load-url');
    $(this).find('.modal-body').load(loadurl);
});

Replace that line with:

$("#someElement").click(function() {
    window.location.href = window.location.href;
});

or:

$("#someElement").click(function() {
    window.location.reload();
});

One gotcha I have found is where two objects contain references to each other (one example being a parent/child relationship with a convenience method on the parent to get all children).
These sorts of things are fairly common when doing Hibernate mappings for example.

If you include both ends of the relationship in your hashCode or equals tests it's possible to get into a recursive loop which ends in a StackOverflowException.
The simplest solution is to not include the getChildren collection in the methods.

Run this command:

select @@version

If you don't need it to be human-readable/editable, the easiest solution is to just use pickle.

To write:

with open(the_filename, 'wb') as f:
    pickle.dump(my_list, f)

To read:

with open(the_filename, 'rb') as f:
    my_list = pickle.load(f)

If you do need them to be human-readable, we need more information.

If my_list is guaranteed to be a list of strings with no embedded newlines, just write them one per line:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write(s + '\n')

with open(the_filename, 'r') as f:
    my_list = [line.rstrip('\n') for line in f]

If they're Unicode strings rather than byte strings, you'll want to encode them. (Or, worse, if they're byte strings, but not necessarily in the same encoding as your system default.)

If they might have newlines, or non-printable characters, etc., you can use escaping or quoting. Python has a variety of different kinds of escaping built into the stdlib.

Let's use unicode-escape here to solve both of the above problems at once:

with open(the_filename, 'w') as f:
    for s in my_list:
        f.write((s + u'\n').encode('unicode-escape'))

with open(the_filename, 'r') as f:
    my_list = [line.decode('unicode-escape').rstrip(u'\n') for line in f]

You can also use the 3.x-style solution in 2.x, with either the codecs module or the io module:*

import io

with io.open(the_filename, 'w', encoding='unicode-escape') as f:
    f.writelines(line + u'\n' for line in my_list)

with open(the_filename, 'r') as f:
    my_list = [line.rstrip(u'\n') for line in f]

_{* TOOWTDI, so which is the one obvious way? It depends… For the short version: if you need to work with Python versions before 2.6, use codecs; if not, use io.}

issue is data table is called before the data table is drawn on DOM,use set time out before calling data table.

setTimeout(function(){ 
    var table = $('#exampleSummary').removeAttr('width').DataTable( {
        scrollY:        "300px",
        scrollX:        true,
        scrollCollapse: true,
        paging:         true,
        columnDefs: [
            { width: 200, targets: 0 }
        ],
        fixedColumns: false
    } );
}, 100);

Following the @greg0ire suggestion in comments:

<input type="submit" name="add_tag" value="Lägg till tag" />

In your server side, you'll do something like:

if (request.getParameter("add_tag") != null)
    tags.addTag( /*...*/ );

(Since I don't know that language (java?), there may be syntax errors.)

I would prefer the <button> solution, but it doesn't work as expected on IE < 9.

Try this

const foo = numberOfItems=> [...Array(numberOfItems).keys()].map(i => i+1);

Use the keyword and, not & because & is a bit operator.

Be careful with this... just so you know, in Java and C++, the & operator is ALSO a bit operator. The correct way to do a boolean comparison in those languages is &&. Similarly | is a bit operator, and || is a boolean operator. In Python and and or are used for boolean comparisons.

Ultimately it probably doesn't have a safe .get method because a dict is an associative collection (values are associated with names) where it is inefficient to check if a key is present (and return its value) without throwing an exception, while it is super trivial to avoid exceptions accessing list elements (as the len method is very fast). The .get method allows you to query the value associated with a name, not directly access the 37th item in the dictionary (which would be more like what you're asking of your list).

Of course, you can easily implement this yourself:

def safe_list_get (l, idx, default):
  try:
    return l[idx]
  except IndexError:
    return default

You could even monkeypatch it onto the __builtins__.list constructor in __main__, but that would be a less pervasive change since most code doesn't use it. If you just wanted to use this with lists created by your own code you could simply subclass list and add the get method.

See what is available in Jetty for storing password (or hashes) in configuration files, and consider if the OBF encoding might be useful for you. Then see in the source how it is done.

Checking Google's index page is another way to do it:

#!/bin/bash

WGET="/usr/bin/wget"

$WGET -q --tries=20 --timeout=10 http://www.google.com -O /tmp/google.idx &> /dev/null
if [ ! -s /tmp/google.idx ]
then
    echo "Not Connected..!"
else
    echo "Connected..!"
fi

JAVA VERSION COULD BE PROBLEM:

I tried few answers given above. But it didnot work. But meanwhile I was trying them it clicked to me that I switched the java version for some other stuff & forgot to switch back.

Once I jumped back to the previous version. Eclipse started working for me.

To make it work I build my directory like this:

Project Public Restrict

So I edited my webconfig for my public folder:

<location path="Project/Public">
    <system.web>
      <authorization>
        <allow users="?"/>
      </authorization>
    </system.web>
  </location>

And for my Restricted folder:

 <location path="Project/Restricted">
    <system.web>
      <authorization>
        <allow users="*"/>
      </authorizatio>
    </system.web>
  </location>

See here for the spec of * and ?:

I hope I have helped.

I know this is not a secure solution, but sometimes you need just a simple solution - without installing anything else. And since helper = store did not work for me, I created a dummy helper:

Create a script and put it in your users bin folder, here named credfake, this script will provide your username and your password:

#!/bin/bash
while read line
do
  echo "$line"
done < "/dev/stdin"
echo username=mahuser
echo password=MahSecret12345

make it executable:

chmod u+x /home/mahuser/bin/credfake

then configure it in git:

git config --global credential.helper /home/mahuser/bin/credfake

(or use it without --global for the one repo only)

and - voilá - git will use this user + password.
