There is no subquery needed with this statement, which is better written as

select u.* 
from Users u, CompanyRolesToUsers c
where u.Id = c.UserId        --join just specified here, perfectly fine
and u.lastname like '%fra%'
and c.CompanyRoleId in (2,3,4)

or

select u.* 
from Users u inner join CompanyRolesToUsers c
             on u.Id = c.UserId    --explicit "join" statement, no diff from above, just preference
where u.lastname like '%fra%'
  and c.CompanyRoleId in (2,3,4)

That being said, in LINQ it would be

from u in Users
from c in CompanyRolesToUsers 
where u.Id == c.UserId &&
      u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

or

from u in Users
join c in CompanyRolesToUsers 
       on u.Id equals c.UserId
where u.LastName.Contains("fra") &&
      selectedRoles.Contains(c.CompanyRoleId)
select u

Which again, are both respectable ways to represent this. I prefer the explicit "join" syntax in both cases myself, but there it is...

you want fix it can edit file "/Applications/XAMPP/xamppfiles/xampp" with TextEdit.

Look for text "$XAMPP_ROOT/bin/mysql.server start > /dev/null &"
And add "unset DYLD_LIBRARY_PATH" on top of it. It should look like:

unset DYLD_LIBRARY_PATH
$XAMPP_ROOT/bin/mysql.server start > /dev/null &

hope can help you

Just add in the missing:

<span class="ui-button-icon-primary ui-icon ui-icon-closethick"></span>
<span class="ui-button-text">close</span>

I still think that Harry's answer is the simplest and completed but if you need something even simpler, then use:

struct AppError {
    let message: String

    init(message: String) {
        self.message = message
    }
}

extension AppError: LocalizedError {
    var errorDescription: String? { return message }
//    var failureReason: String? { get }
//    var recoverySuggestion: String? { get }
//    var helpAnchor: String? { get }
}

And use or test it like this:

printError(error: AppError(message: "My App Error!!!"))

func print(error: Error) {
    print("We have an ERROR: ", error.localizedDescription)
}

**var spge = '';** 
alert(spge);

The easiest way would be to flush the stream multiple times ( ideally larger then any possible console ) 1024*1024 is likely a size no console window could ever be.

int main(int argc, char *argv)
{
  for(int i = 0; i <1024*1024; i++)
      std::cout << ' ' << std::endl;

  return 0;
}

The only problem with this is the software cursor; that blinking thing ( or non blinking thing ) depending on platform / console will be at the end of the console, opposed to the top of it. However this should never induce any trouble hopefully.

grep '^[0-9]\{1,16\}' | wc -l

Gives the counts with exact match count with limit

Easier solution;

#/bin/bash
if (( ${1:-2} >= 2 )); then
    echo "First parameter must be 0 or 1"
fi
# rest of script...

Output

$ ./test 
First parameter must be 0 or 1
$ ./test 0
$ ./test 1
$ ./test 4
First parameter must be 0 or 1
$ ./test 2
First parameter must be 0 or 1

Explanation

• (( )) - Evaluates the expression using integers.
• ${1:-2} - Uses parameter expansion to set a value of 2 if undefined.
• >= 2 - True if the integer is greater than or equal to two 2.

What worked best for me is

scroll_view.post(new Runnable() {
     @Override
     public void run() {
         // This method works but animates the scrolling 
         // which looks weird on first load
         // scroll_view.fullScroll(View.FOCUS_DOWN);

         // This method works even better because there are no animations.
         scroll_view.scrollTo(0, scroll_view.getBottom());
     }
});

I found the solution to a similar problem. I am using Gradle 1.11 (as April, 2014). The project name can be changed directly in settings.gradle file as following:

  rootProject.name='YourNewName'

This takes care of uploading to repository (Artifactory w/ its plugin for me) with the correct artifactId.

MySQL 5.6 (LAMP) . column_value is the column you want to add up. table_name is the table.

Method #1

$qry = "SELECT column_value AS count
        FROM table_name ";

$res = $db->query($qry);

$total = 0;
while ($rec = $db->fetchAssoc($res)) {
    $total += $rec['count'];
}
echo "Total: " . $total . "\n";

Method #2

$qry = "SELECT SUM(column_value) AS count 
        FROM table_name ";

$res = $db->query($qry);

$total = 0;
$rec = $db->fetchAssoc($res);
$total = $rec['count'];

echo "Total: " . $total . "\n";

Method #3 -SQLi

$qry = "SELECT SUM(column_value) AS count 
        FROM table_name ";

$res = $conn->query($sql);

$total = 0;
$rec = row = $res->fetch_assoc();
$total = $rec['count'];

echo "Total: " . $total . "\n";

Method #4: Depreciated (don't use)

$res = mysql_query('SELECT SUM(column_value) AS count FROM table_name'); 
$row = mysql_fetch_assoc($res); 
$sum = $row['count'];

From http://php.net/manual/en/function.serialize.php :

Generates a storable representation of a value. This is useful for storing or passing PHP values around without losing their type and structure.

Essentially, it takes a php array or object and converts it to a string (which you can then transmit or store as you see fit).

Unserialize is used to convert the string back to an object.

The approximate conversions are:

• Latitude: 1 deg = 110.574 km
• Longitude: 1 deg = 111.320*cos(latitude) km

This doesn't fully correct for the Earth's polar flattening - for that you'd probably want a more complicated formula using the WGS84 reference ellipsoid (the model used for GPS). But the error is probably negligible for your purposes.

Source: http://en.wikipedia.org/wiki/Latitude

Caution: Be aware that latlong coordinates are expressed in degrees, while the cos function in most (all?) languages typically accepts radians, therefore a degree to radians conversion is needed.

Or try this. It will capture output into variable $scriptOutput:

& "netdom.exe" $params | Tee-Object -Variable scriptOutput | Out-Null

$scriptOutput

(document.body.outerHTML).constructor will return String. (take off .constructor and that's your string)

That aughta do it :)

The code was most likely compiled with a later JDK (without using cross-compilation options) and is being run on an earlier JRE. While upgrading the JRE is one solution, it would be better to use the cross-compilation options to ensure the code will run on whatever JRE is intended as the minimum version for the app.

I think you need this ..

Dim n as Integer   

For n = 5 to 17
  msgbox cells(n,3) '--> sched waste
  msgbox cells(n,4) '--> type of treatm
  msgbox format(cells(n,5),"dd/MM/yyyy") '--> Lic exp
  msgbox cells(n,6) '--> email col

If you want to use the new android.support.v7.app.AlertDialog and have different colors for the buttons and also have a custom layout then have a look at my https://gist.github.com/JoachimR/6bfbc175d5c8116d411e

@NonNull
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    View v = inflater.inflate(R.layout.custom_layout, null);

    initDialogUi(v);

    final AlertDialog d = new AlertDialog.Builder(activity, R.style.AppCompatAlertDialogStyle)
            .setTitle(getString(R.string.some_dialog_title))
            .setCancelable(true)
            .setPositiveButton(activity.getString(R.string.some_dialog_title_btn_positive),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            doSomething();
                            dismiss();
                        }
                    })
            .setNegativeButton(activity.getString(R.string.some_dialog_title_btn_negative),
                    new DialogInterface.OnClickListener() {
                        @Override
                        public void onClick(DialogInterface dialog, int which) {
                            dismiss();
                        }
                    })
            .setView(v)
            .create();

    // change color of positive button         
    d.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            Button b = d.getButton(DialogInterface.BUTTON_POSITIVE);
            b.setTextColor(getResources().getColor(R.color.colorPrimary));
        }
    });

    return d;
}

Another option that may be useful is a dedicated HTTP debugging tool. There's a few available, I'd suggest HTTP Toolkit: an open-source project I've been working on (yeah, I might be biased) to solve this same problem for myself.

The main difference is usability & power. The Chrome dev tools are good for simple things, and I'd recommend starting there, but if you're struggling to understand the information there, and you need either more explanation or more power then proper focused tools can be useful!

For this case, it'll show you the full POST body you're looking for, with a friendly editor and highlighting (all powered by VS Code) so you can dig around. It'll give you the request & response headers of course, but with extra info like docs from MDN (the Mozilla Developer Network) for every standard header and status code you can see.

A picture is worth a thousand StackOverflow answers:

Also check that you are not using validation groups as that validation wouldnt fire if the validationgroup property was set and not explicitly called via

 Page.Validate({Insert validation group name here});

In addition to all the other answers, you could use switch. But it does seem a bit long.

switch ($result->vocation) {
case 1:
    echo 'Sorcerer';
    break;

case 2:
    echo 'Druid';
    break;

case 3:
    echo 'Paladin';
    break;

case 4:
    echo 'Knight';
    break;

case 5:
    echo 'Master Sorcerer';
    break;

case 6:
    echo 'Elder Druid';
    break;

case 7:
    echo 'Royal Paladin';
    break;

default:
    echo 'Elite Knight';
    break;
}

Explanation of Serialize and Deserialize using Python

In python, pickle module is used for serialization. So, the serialization process is called pickling in Python. This module is available in Python standard library.

Serialization using pickle

import pickle

#the object to serialize
example_dic={1:"6",2:"2",3:"f"}

#where the bytes after serializing end up at, wb stands for write byte
pickle_out=open("dict.pickle","wb")
#Time to dump
pickle.dump(example_dic,pickle_out)
#whatever you open, you must close
pickle_out.close()

The PICKLE file (can be opened by a text editor like notepad) contains this (serialized data):

€}q (KX 6qKX 2qKX fqu.

Deserialization using pickle

import pickle

pickle_in=open("dict.pickle","rb")
get_deserialized_data_back=pickle.load(pickle_in)

print(get_deserialized_data_back)

Output:

{1: '6', 2: '2', 3: 'f'}

Replace this

 <button type="button" value=" Send" class="btn btn-success" type="submit" id="submit">

with

<button  value=" Send" class="btn btn-success" type="submit" id="submit">

What i did to fix this issue was in the page where my break-point was not hitting, i selected the folder > add an existing item and then select the item from its save path. This allowed the break point to start working.

Yes, you can make a button not submit a form by adding an attribute of type of value button: <button type="button"><button>

I had this issue in xcode 6 and there is a way to resolve the resize conflicts. If you select your view, at the bottom you will see an icon that looks like |-Δ-|. If you click on it, you're project will resize for different devices.

Feb 2016 version: Admin tab, then select Property in the middle column, click Property Settings, then the Move To Trash Can button at the top right. No need to delete individual views.

Why not encapsulate a set with a list, sort like:

new ArrayList( new LinkedHashSet() )

This leaves the other implementation for someone who is a real master of Collections ;-)

Check Below Codes :

1. SynchonousRequest

Swift 1.2

    let urlPath: String = "YOUR_URL_HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSURLRequest = NSURLRequest(URL: url)
    var response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil
    var dataVal: NSData =  NSURLConnection.sendSynchronousRequest(request1, returningResponse: response, error:nil)!
    var err: NSError
    println(response)
    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal, options: NSJSONReadingOptions.MutableContainers, error: &err) as? NSDictionary
    println("Synchronous\(jsonResult)")

Swift 2.0 +

let urlPath: String = "YOUR_URL_HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSURLRequest = NSURLRequest(URL: url)
    let response: AutoreleasingUnsafeMutablePointer<NSURLResponse?>=nil


    do{

        let dataVal = try NSURLConnection.sendSynchronousRequest(request1, returningResponse: response)

            print(response)
            do {
                if let jsonResult = try NSJSONSerialization.JSONObjectWithData(dataVal, options: []) as? NSDictionary {
                    print("Synchronous\(jsonResult)")
                }
            } catch let error as NSError {
                print(error.localizedDescription)
            }



    }catch let error as NSError
    {
         print(error.localizedDescription)
    }

2. AsynchonousRequest

Swift 1.2

let urlPath: String = "YOUR_URL_HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSURLRequest = NSURLRequest(URL: url)
    let queue:NSOperationQueue = NSOperationQueue()
    NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in
        var err: NSError
        var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
        println("Asynchronous\(jsonResult)")
       })

Swift 2.0 +

let urlPath: String = "YOUR_URL_HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSURLRequest = NSURLRequest(URL: url)
    let queue:NSOperationQueue = NSOperationQueue()

    NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in

        do {
            if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
                print("ASynchronous\(jsonResult)")
            }
        } catch let error as NSError {
            print(error.localizedDescription)
        }


    })

3. As usual URL connection

Swift 1.2

    var dataVal = NSMutableData()
    let urlPath: String = "YOUR URL HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request: NSURLRequest = NSURLRequest(URL: url)
    var connection: NSURLConnection = NSURLConnection(request: request, delegate: self, startImmediately: true)!
    connection.start()

Then

 func connection(connection: NSURLConnection!, didReceiveData data: NSData!){
    self.dataVal?.appendData(data)
}


func connectionDidFinishLoading(connection: NSURLConnection!)
{
    var error: NSErrorPointer=nil

    var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(dataVal!, options: NSJSONReadingOptions.MutableContainers, error: error) as NSDictionary

    println(jsonResult)



}

Swift 2.0 +

   var dataVal = NSMutableData()
    let urlPath: String = "YOUR URL HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request: NSURLRequest = NSURLRequest(URL: url)
    var connection: NSURLConnection = NSURLConnection(request: request, delegate: self, startImmediately: true)!
    connection.start()

Then

func connection(connection: NSURLConnection!, didReceiveData data: NSData!){
    dataVal.appendData(data)
}


func connectionDidFinishLoading(connection: NSURLConnection!)
{

    do {
        if let jsonResult = try NSJSONSerialization.JSONObjectWithData(dataVal, options: []) as? NSDictionary {
            print(jsonResult)
        }
    } catch let error as NSError {
        print(error.localizedDescription)
    }

}

4. Asynchonous POST Request

Swift 1.2

    let urlPath: String = "YOUR URL HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSMutableURLRequest = NSMutableURLRequest(URL: url)

    request1.HTTPMethod = "POST"
     var stringPost="deviceToken=123456" // Key and Value

    let data = stringPost.dataUsingEncoding(NSUTF8StringEncoding)

    request1.timeoutInterval = 60
    request1.HTTPBody=data
    request1.HTTPShouldHandleCookies=false

    let queue:NSOperationQueue = NSOperationQueue()

     NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in


        var err: NSError

        var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
        println("AsSynchronous\(jsonResult)")


        })

Swift 2.0 +

let urlPath: String = "YOUR URL HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSMutableURLRequest = NSMutableURLRequest(URL: url)

    request1.HTTPMethod = "POST"
    let stringPost="deviceToken=123456" // Key and Value

    let data = stringPost.dataUsingEncoding(NSUTF8StringEncoding)

    request1.timeoutInterval = 60
    request1.HTTPBody=data
    request1.HTTPShouldHandleCookies=false

    let queue:NSOperationQueue = NSOperationQueue()

    NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in

        do {
            if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
                print("ASynchronous\(jsonResult)")
            }
        } catch let error as NSError {
            print(error.localizedDescription)
        }


    })

5. Asynchonous GET Request

Swift 1.2

    let urlPath: String = "YOUR URL HERE"
    var url: NSURL = NSURL(string: urlPath)!
    var request1: NSMutableURLRequest = NSMutableURLRequest(URL: url)

    request1.HTTPMethod = "GET"
    request1.timeoutInterval = 60
    let queue:NSOperationQueue = NSOperationQueue()

     NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse!, data: NSData!, error: NSError!) -> Void in


        var err: NSError

        var jsonResult: NSDictionary = NSJSONSerialization.JSONObjectWithData(data, options: NSJSONReadingOptions.MutableContainers, error: nil) as NSDictionary
        println("AsSynchronous\(jsonResult)")


        })

Swift 2.0 +

let urlPath: String = "YOUR URL HERE"
    let url: NSURL = NSURL(string: urlPath)!
    let request1: NSMutableURLRequest = NSMutableURLRequest(URL: url)

    request1.HTTPMethod = "GET"
    let queue:NSOperationQueue = NSOperationQueue()

    NSURLConnection.sendAsynchronousRequest(request1, queue: queue, completionHandler:{ (response: NSURLResponse?, data: NSData?, error: NSError?) -> Void in

        do {
            if let jsonResult = try NSJSONSerialization.JSONObjectWithData(data!, options: []) as? NSDictionary {
                print("ASynchronous\(jsonResult)")
            }
        } catch let error as NSError {
            print(error.localizedDescription)
        }


    })

6. Image(File) Upload

Swift 2.0 +

  let mainURL = "YOUR_URL_HERE"

    let url = NSURL(string: mainURL)
    let request = NSMutableURLRequest(URL: url!)
    let boundary = "78876565564454554547676"
    request.addValue("multipart/form-data; boundary=\(boundary)", forHTTPHeaderField: "Content-Type")


    request.HTTPMethod = "POST" // POST OR PUT What you want
    let session = NSURLSession(configuration:NSURLSessionConfiguration.defaultSessionConfiguration(), delegate: nil, delegateQueue: nil)

    let imageData = UIImageJPEGRepresentation(UIImage(named: "Test.jpeg")!, 1)





    var body = NSMutableData()

    body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    // Append your parameters

    body.appendData("Content-Disposition: form-data; name=\"name\"\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    body.appendData("PREMKUMAR\r\n".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)!)
    body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    body.appendData("Content-Disposition: form-data; name=\"description\"\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    body.appendData("IOS_DEVELOPER\r\n".dataUsingEncoding(NSUTF8StringEncoding, allowLossyConversion: true)!)
    body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)


    // Append your Image/File Data

    var imageNameval = "HELLO.jpg"

    body.appendData("--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    body.appendData("Content-Disposition: form-data; name=\"profile_photo\"; filename=\"\(imageNameval)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    body.appendData("Content-Type: image/jpeg\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    body.appendData(imageData!)
    body.appendData("\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    body.appendData("--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    request.HTTPBody = body




    let dataTask = session.dataTaskWithRequest(request) { (data, response, error) -> Void in

        if error != nil {

            //handle error


        }
        else {




            let outputString : NSString = NSString(data:data!, encoding:NSUTF8StringEncoding)!
            print("Response:\(outputString)")


        }
    }
    dataTask.resume()

Using a thread pool is a good option, and will make this fairly easy. Unfortunately, python doesn't have a standard library that makes thread pools ultra easy. But here is a decent library that should get you started: http://www.chrisarndt.de/projects/threadpool/

Code example from their site:

pool = ThreadPool(poolsize)
requests = makeRequests(some_callable, list_of_args, callback)
[pool.putRequest(req) for req in requests]
pool.wait()

Hope this helps.

In my case i was returning string value from my api eg: "35" and in my HTML i was using

       <mat-select placeholder="State*" formControlName="states" [(ngModel)]="selectedState" (ngModelChange)="getDistricts()">
            <mat-option *ngFor="let state of formInputs.states" [value]="state.stateId">
              {{ state.stateName }}
            </mat-option>
          </mat-select>

Like others mentioned in the comment value will only accept integer values i guess. So what I did is I converted my string value to integer in my component class like below

          var x = user.state;
          var y: number = +x;

and then assigned it like

  this.EditProfileForm.get('states').setValue(y);

Now the correct values is getting setting by default.

Simply put, if an exception or error is thrown, something's wrong. It may not be something very wrong, but creating, throwing, and catching errors and exceptions just for the sake of using goto statements is not a good idea, and it's rarely done. 99% of the time, there was a problem somewhere.

Problems need to be dealt with. Just like how it is in life, in programming, if you just leave problems alone and try to ignore them, they don't just go away on their own a lot of times; instead they get bigger and multiply. To prevent a problem from growing on you and striking again further down the road, you either 1) eliminate it and clean up the mess afterwards, or 2) contain it and clean up the mess afterwards.

Just ignoring exceptions and errors and leaving them be like that is a good way to experience memory leaks, outstanding database connections, needless locks on file permissions, etc.

On rare occasions, the problem is so miniscule, trivial, and - aside from needing a try...catch block - self-contained, that there really is just no mess to be cleaned up afterwards. These are the only occasions when this best practice doesn't necessarily apply. In my experience, this has generally meant that whatever the code is doing is basically petty and forgoable, and something like retry attempts or special messages are worth neither the complexity nor holding the thread up on.

At my company, the rule is to almost always do something in a catch block, and if you don't do anything, then you must always place a comment with a very good reason why not. You must never pass or leave an empty catch block when there is anything to be done.

This problem happens because IIS does not know about woff and woff2 file mime types.

Solution 1:

Add these lines in your web.config project:

 <system.webServer>
  ...
  </modules>
    <staticContent>
      <remove fileExtension=".woff" />
      <mimeMap fileExtension=".woff" mimeType="application/font-woff" />
      <remove fileExtension=".woff2" />
      <mimeMap fileExtension=".woff2" mimeType="font/woff2" />
    </staticContent>

Solution 2:

On IIS project page:

Step 1: Go to your project IIS home page and double click on MIME Types button:

Step 2: Click on Add button from Actions menu:

Step 3: In the middle of the screen appears a window and in this window you need to add the two lines from solution 1:

here is example of @dynamic

#import <Foundation/Foundation.h>

@interface Book : NSObject
{
   NSMutableDictionary *data;
}
@property (retain) NSString *title;
@property (retain) NSString *author;
@end

@implementation Book
@dynamic title, author;

- (id)init
{
    if ((self = [super init])) {
        data = [[NSMutableDictionary alloc] init];
        [data setObject:@"Tom Sawyer" forKey:@"title"];
        [data setObject:@"Mark Twain" forKey:@"author"];
    }
    return self;
}

- (void)dealloc
{
    [data release];
    [super dealloc];
}

- (NSMethodSignature *)methodSignatureForSelector:(SEL)selector
{
    NSString *sel = NSStringFromSelector(selector);
    if ([sel rangeOfString:@"set"].location == 0) {
        return [NSMethodSignature signatureWithObjCTypes:"v@:@"];
    } else {
        return [NSMethodSignature signatureWithObjCTypes:"@@:"];
    }
 }

- (void)forwardInvocation:(NSInvocation *)invocation
{
    NSString *key = NSStringFromSelector([invocation selector]);
    if ([key rangeOfString:@"set"].location == 0) {
        key = [[key substringWithRange:NSMakeRange(3, [key length]-4)] lowercaseString];
        NSString *obj;
        [invocation getArgument:&obj atIndex:2];
        [data setObject:obj forKey:key];
    } else {
        NSString *obj = [data objectForKey:key];
        [invocation setReturnValue:&obj];
    }
}

@end

int main(int argc, char **argv)
{
    NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];

    Book *book = [[Book alloc] init];

Don't delete it: for just one commit git cherry-pick is enough.

But if you had several commits on the wrong branch, that is where git rebase --onto shines:

Suppose you have this:

 x--x--x--x <-- master
           \
            -y--y--m--m <- y branch, with commits which should have been on master

, then you can mark master and move it where you would want to be:

 git checkout master
 git branch tmp
 git checkout y
 git branch -f master

 x--x--x--x <-- tmp
           \
            -y--y--m--m <- y branch, master branch

, reset y branch where it should have been:

 git checkout y
 git reset --hard HEAD~2 # ~1 in your case, 
                         # or ~n, n = number of commits to cancel

 x--x--x--x <-- tmp
           \
            -y--y--m--m <- master branch
                ^
                |
                -- y branch

, and finally move your commits (reapply them, making actually new commits)

 git rebase --onto tmp y master
 git branch -D tmp


 x--x--x--x--m'--m' <-- master
           \
            -y--y <- y branch

To install an APK on your mobile, you can either:

1. Use ADB from the Android SDK, and do the following command: adb install filename.apk. Note, you'll need to enable USB debugging for this to work.
2. Transfer the file to your device, then open it with a file manager, such as Linda File Manager.

Note, that you'll have to enable installing packages from Unknown Sources in your Applications settings.

As for getting USB to work, I suggest consulting the Android StackExchange for advice.

You are printing the wrong value. Instead if the string you print the scanners object. Try this

Scanner input = new Scanner(System.in);
String s = input.next();
System.out.println(s);

You can't. If you have a method called isBiggerThanMaxLong(long) it should always return false.

If you were to increment the bits of Long.MAX_VALUE, the next value should be Long.MIN_VALUE. Read up on twos-complement and that should tell you why.

Using Python's built in range function:

Python 2

input = 8
output = range(input + 1)

print output
[0, 1, 2, 3, 4, 5, 6, 7, 8]

Python 3

input = 8
output = list(range(input + 1))

print(output)
[0, 1, 2, 3, 4, 5, 6, 7, 8]

The excellent (free trial) IcoFX allows you to create and edit icons, including multiple sizes up to 256x256, PNG compression, and transparency. I highly recommend it over most of the alternates.

Get your copy here: http://icofx.ro/ . It supports Windows XP onwards.

Windows automatically chooses the proper icon from the file, depending on where it is to be displayed. For more information on icon design and the sizes/bit depths you should include, see these references:

• Icons (Windows Aero)

• Creating Windows XP Icons

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

The simple way is to create table as textfile and move the file to the appropriate location

CREATE EXTERNAL TABLE mytable(col1 string, col2 string)
row format delimited fields terminated by '|' stored as textfile;

Copy the file to the HDFS Location where table is created.
Hope this helps!!!

Edit: seems I was wrong in assuming you could not get the element. As others have posted here, you can get it with:

$('#element').get(0);

I have verified this actually returns the DOM element that was matched.

I think you are looking for the IGNORE_DUP_KEY option on your index. Have a look at IGNORE_DUP_KEY ON option documented at http://msdn.microsoft.com/en-us/library/ms186869.aspx which causes duplicate insertion attempts to produce a warning instead of an error.

=SUMPRODUCT((A1:A5="FRANCE")*B1:D5)

All of the answers given here wont work since java's UTF-8 writing is bugged.

http://tripoverit.blogspot.com/2007/04/javas-utf-8-and-unicode-writing-is.html

Should work.

Here's a working example:

http://jsfiddle.net/rhpNc/

Excerpt:

function loadIframe(iframeName, url) {
    var $iframe = $('#' + iframeName);
    if ($iframe.length) {
        $iframe.attr('src',url);
        return false;
    }
    return true;
}

I just encountered this problem myself and found that Ubuntu 14.04 uses Upstart instead of Systemd, so systemctl commands will not work. This changed in 15.04, so one way around this would be to update your ubuntu install.

If this is not an option for you (it's not for me right now), you need to find the Upstart command that does what you need to do.

For enable, the generic looks to be the following:

update-rc.d <service> enable

Link to Ubuntu documentation: https://wiki.ubuntu.com/SystemdForUpstartUsers

The default conversion from an object to string is "[object Object]".

As you are dealing with jQuery objects, you might want to do

alert(whichIsVisible()[0].id);

to print the element's ID.

As mentioned in the comments, you should use the tools included in browsers like Firefox or Chrome to introspect objects by doing console.log(whichIsVisible()) instead of alert.

Sidenote: IDs should not start with digits.

I tried one of the previous answers in a web app (actually an Azure web role running locally) and it didn't quite work. However, this similar approach did work:

var map = new ExeConfigurationFileMap { ExeConfigFilename = "MyComponent.dll.config" };
var path = ConfigurationManager.OpenMappedExeConfiguration(map, ConfigurationUserLevel.None).FilePath;

The config file turned out to be in C:\Program Files\IIS Express\MyComponent.dll.config. Interesting place for it.

I had the same error message, my mistake was that I had a semicolon at the end of COMMIT TRANSACTION line

this helpful for you..

$('.handle').css('left', '300px');

Using REQUIRES_NEW is only relevant when the method is invoked from a transactional context; when the method is invoked from a non-transactional context, it will behave exactly as REQUIRED - it will create a new transaction.

That does not mean that there will only be one single transaction for all your clients - each client will start from a non-transactional context, and as soon as the the request processing will hit a @Transactional, it will create a new transaction.

So, with that in mind, if using REQUIRES_NEW makes sense for the semantics of that operation - than I wouldn't worry about performance - this would textbook premature optimization - I would rather stress correctness and data integrity and worry about performance once performance metrics have been collected, and not before.

On rollback - using REQUIRES_NEW will force the start of a new transaction, and so an exception will rollback that transaction. If there is also another transaction that was executing as well - that will or will not be rolled back depending on if the exception bubbles up the stack or is caught - your choice, based on the specifics of the operations. Also, for a more in-depth discussion on transactional strategies and rollback, I would recommend: «Transaction strategies: Understanding transaction pitfalls», Mark Richards.

Try this:

satView = (CheckBox) findViewById(R.id.sateliteCheckBox);

satView.setOnCheckedChangeListener(new OnCheckedChangeListener() {
    @Override 
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
          if (buttonView.isChecked()) { 
                // checked
          } 
          else 
          {
                // not checked
          }
    }

});

Hope this helps.

There are three ways I know to create a directory using PowerShell:

Method 1: PS C:\> New-Item -ItemType Directory -path "C:\livingston"

Method 2: PS C:\> [system.io.directory]::CreateDirectory("C:\livingston")

Method 3: PS C:\> md "C:\livingston"

Depends on your needs, if you know what parent your looking for you can use the .parents() selector.

E.G: http://jsfiddle.net/HenryGarle/Kyp5g/2/

<div id="One">
    <div id="Two">
        <div id="Three">
            <div id="Four">

            </div>
        </div>
    </div>
</div>


var top = $("#Four").parents("#One");

alert($(top).html());

Example using index:

//First parent - 2 levels up from #Four
// I.e Selects div#One
var topTwo = $("#Four").parents().eq(2);

alert($(topTwo ).html());

Usually, this problem resolve with using the modulo of a number in a loop or convert a number to a string. For convert a number to a string, you may can use the function itoa, so considering the variant with the modulo of a number in a loop.

Check the error_reporting flag, must be E_ALL, but in some release of Plesk there are quotes ("E_ALL") instead of (E_ALL)

I solved this issue deleting the quotes (") in php.ini

from this:

error_reporting = "E_ALL"

to this:

error_reporting = E_ALL

Here is how you define a react onClick event handler, which was answering the question title... using es6 syntax

import React, { Component } from 'react';

export default class Test extends Component {
  handleClick(e) {
    e.preventDefault()
    console.log(e.target)
  }

  render() {
    return (
      <a href='#' onClick={e => this.handleClick(e)}>click me</a>
    )
  }
}

Try using

Dir.glob(".") 

To see what's in the directory (and therefore what directory it's looking at).

look at overloaded Sort method of the List class. there are some ways to to it. one of them: your custom class has to implement IComparable interface then you cam use Sort method of the List class.

I can't comment on how efficient this is, but here's a solution:

applyToGivenRow = @(func, matrix) @(row) func(matrix(row, :))
applyToRows = @(func, matrix) arrayfun(applyToGivenRow(func, matrix), 1:size(matrix,1))'

% Example
myMx = [1 2 3; 4 5 6; 7 8 9];
myFunc = @sum;

applyToRows(myFunc, myMx)

In my case there was problem in URL. I've use https://example.com - but they ensure 'www.' - so when i switched to https://www.example.com everything was ok. The proper header was sent 'Host: www.example.com'.

You can try make a request in firefox brwoser, persist it and copy as cURL - that how I've found it.

Here is @Vitaliy Gozhenko's answer, in Swift.
To summarize you will create a UITableViewHeaderFooterView that contains a UITableViewCell. This UITableViewCell will be "dequeuable" and you can design it in your storyboard.

1. Create a UITableViewHeaderFooterView class

   class CustomHeaderFooterView: UITableViewHeaderFooterView {
   var cell : UITableViewCell? {
       willSet {
           cell?.removeFromSuperview()
       }
       didSet {
           if let cell = cell {
               cell.frame = self.bounds
               cell.autoresizingMask = [UIViewAutoresizing.FlexibleHeight, UIViewAutoresizing.FlexibleWidth]
               self.contentView.backgroundColor = UIColor .clearColor()
               self.contentView .addSubview(cell)
           }
       }
   }
   

2. Plug your tableview with this class in your viewDidLoad function:

   self.tableView.registerClass(CustomHeaderFooterView.self, forHeaderFooterViewReuseIdentifier: "SECTION_ID")
   

3. When asking, for a section header, dequeue a CustomHeaderFooterView, and insert a cell into it

   func tableView(tableView: UITableView, viewForHeaderInSection section: Int) -> UIView? {
       let view = self.tableView.dequeueReusableHeaderFooterViewWithIdentifier("SECTION_ID") as! CustomHeaderFooterView
       if view.cell == nil {
           let cell = self.tableView.dequeueReusableCellWithIdentifier("Cell")
           view.cell = cell;
       }
   
       // Fill the cell with data here
   
       return view;
   }
   

If you installed the command line tools separately, delete them using:

sudo rm -rf /Library/Developer/CommandLineTools

Following is a free list of tools you can use to check, test and verify your JS code:

1. Google Code Playground
2. JavaScript Sandbox
3. jsbin
4. jsfiddle
5. pastebin
6. jsdo.it
7. firebug
8. html5snippet.net

This is a pretty old feature request: Allow webdriver to attach to a running browser . So it's officially not supported.

However, there is some working code which claims to support this: https://web.archive.org/web/20171214043703/http://tarunlalwani.com/post/reusing-existing-browser-session-selenium-java/.

Enclose your code with the html and body tags. Size attribute does not correspond to font-size and it looks like its domain does not go beyond value 7. Furthermore font tag is not supported in HTML5. Consider this code for your case

Both of these operations restore a set of files to a previous state and are essentially faster, safer ways of undoing mistakes than using the p4 obliterate command (and you don't need admin access to use them).

In the case of "Rollback...", this could be any number of files, even an entire depot. You can tell it to rollback to a specific revision, changelist, or label. The files are restored to the state they were in at the time of creation of that revision, changelist, or label.

In the case of "Back Out Submitted Changelist #####", the restore operation is restricted to the files that were submitted in changelist #####. Those files are restored to the state they were in before you submitted that changelist, provided no changes have been made to those files since. If subsequent changes have been made to any of those files, Perforce will tell you that those files are now out of date. You will have to sync to the head revision and then resolve the differences. This way you don't inadvertently clobber any changes that you actually want to keep.

Both operations work by essentially submitting old revisions as new revisions. When you perform a "Rollback...", you are restoring the files to the state they were in at a specific point in time, regardless of what has happened to them since. When you perform a "Back out...", you are attempting to undo the changes you made at a specific point in time, while maintaining the changes that have occurred since.

(I just got this working, with my main issue being that I don't have a real internet hostname, so answering this question in case it helps someone)

You need to specify a hostname with HELO. Even so, you should get an error, so Postfix is probably not running.

Also, the => is not a command. The '.' on a single line without any text around it is what tells Postfix that the entry is complete. Here are the entries I used:

telnet localhost 25
(says connected)
EHLO howdy.com
(returns a bunch of 250 codes)
MAIL FROM: [email protected]
RCPT TO: (use a real email address you want to send to)
DATA (type whatever you want on muliple lines)
. (this on a single line tells Postfix that the DATA is complete)

You should get a response like:

250 2.0.0 Ok: queued as 6E414C4643A

The email will probably end up in a junk folder. If it is not showing up, then you probably need to setup the 'Postfix on hosts without a real Internet hostname'. Here is the breakdown on how I completed that step on my Ubuntu box:

sudo vim /etc/postfix/main.cf
smtp_generic_maps = hash:/etc/postfix/generic (add this line somewhere)
(edit or create the file 'generic' if it doesn't exist)
sudo vim /etc/postfix/generic
(add these lines, I don't think it matters what names you use, at least to test)
[email protected]             [email protected]
[email protected]             [email protected]
@localdomain.local                [email protected]
then run:
postmap /etc/postfix/generic (this needs to be run whenever you change the 
generic file)

Happy Trails

foreach (DataRow row in myDataTable.Rows)
{
   Console.WriteLine(row["ImagePath"]);
}

I am writing this from memory.
Hope this gives you enough hint to understand the object model.

DataTable -> DataRowCollection -> DataRow (which one can use & look for column contents for that row, either using columnName or ordinal).

-> = contains.

For Example :

<div class="intrinsic-container">
  <iframe src="//www.youtube.com/embed/KMYrIi_Mt8A" allowfullscreen></iframe>
</div>

CSS 

.intrinsic-container {
  position: relative;
  height: 0;
  overflow: hidden;
}

/* 16x9 Aspect Ratio */
.intrinsic-container-16x9 {
  padding-bottom: 56.25%;
}

/* 4x3 Aspect Ratio */
.intrinsic-container-4x3 {
  padding-bottom: 75%;
}

.intrinsic-container iframe {
  position: absolute;
  top:0;
  left: 0;
  width: 100%;
  height: 100%;
}

You may also want to use Rake::FileList (provided you have rake dependency):

FileList.new('lib/*') do |file|
  p file
end

According to the API:

FileLists are lazy. When given a list of glob patterns for possible files to be included in the file list, instead of searching the file structures to find the files, a FileList holds the pattern for latter use.

https://docs.ruby-lang.org/en/2.1.0/Rake/FileList.html

As mentioned in previous answers, you can cast directly to the underlying datatype (int -> enum type) or parse (string -> enum type).

but beware - there is no .TryParse for enums, so you WILL need a try/catch block around the parse to catch failures.

From the man page:

Sending mail

To send a message to one or more people, mailx can be invoked with arguments which are the names of people to whom the mail will be sent. The user is then expected to type in his message, followed by an ‘control-D’ at the beginning of a line.

In other words, mailx reads the content to send from standard input and can be redirected to like normal. E.g.:

ls -l $HOME | mailx -s "The content of my home directory" [email protected]

Rather than rely on numpy/scipy, I think my answer should be the easiest to code and understand the steps in calculating the Pearson Correlation Coefficient (PCC) .

import math

# calculates the mean
def mean(x):
    sum = 0.0
    for i in x:
         sum += i
    return sum / len(x) 

# calculates the sample standard deviation
def sampleStandardDeviation(x):
    sumv = 0.0
    for i in x:
         sumv += (i - mean(x))**2
    return math.sqrt(sumv/(len(x)-1))

# calculates the PCC using both the 2 functions above
def pearson(x,y):
    scorex = []
    scorey = []

    for i in x: 
        scorex.append((i - mean(x))/sampleStandardDeviation(x)) 

    for j in y:
        scorey.append((j - mean(y))/sampleStandardDeviation(y))

# multiplies both lists together into 1 list (hence zip) and sums the whole list   
    return (sum([i*j for i,j in zip(scorex,scorey)]))/(len(x)-1)

The significance of PCC is basically to show you how strongly correlated the two variables/lists are. It is important to note that the PCC value ranges from -1 to 1. A value between 0 to 1 denotes a positive correlation. Value of 0 = highest variation (no correlation whatsoever). A value between -1 to 0 denotes a negative correlation.

Shelving is a way of saving all of the changes on your box without checking in. The changes are persisted on the server. At any later time you or any of your team-mates can "unshelve" them back onto any one of your machines.

It's also great for review purposes. On my team for a check in we shelve up our changes and send out an email with the change description and name of the changeset. People on the team can then view the changeset and give feedback.

FYI: The best way to review a shelveset is with the following command

tfpt review /shelveset:shelvesetName;userName

tfpt is a part of the Team Foundation Power Tools

<form enctype='multipart/form-data'>
    <input onchange="alert(this.value); this.value=null; return false;" type='file'>
    <br>
    <input type='submit' value='Upload'>
</form>

this.value=null; is only necessary for Chrome, Firefox will work fine just with return false;

Here is a FIDDLE

I tried this as a best guess, but no luck:

It looks right to me. Have you tried setting a message severity explicitly? Also I believe the ID needs to be the same as that of a component (i.e., you'd need to use newPassword1 or newPassword2, if those are your IDs, and not newPassword as you had in the example).

FacesContext.getCurrentInstance().addMessage("newPassword1", 
                    new FacesMessage(FacesMessage.SEVERITY_ERROR, "Error Message"));

Then use <h:message for="newPassword1" /> to display the error message on the JSF page.

With Spring MVC 4.2.1.RELEASE, you need to use the new Jackson2 dependencies as below for the Deserializer to work.

Dont use this

<dependency>  
            <groupId>org.codehaus.jackson</groupId>  
            <artifactId>jackson-mapper-asl</artifactId>  
            <version>1.9.12</version>  
        </dependency>  

Use this instead.

<dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-annotations</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-core</artifactId>
            <version>2.2.2</version>
        </dependency>
        <dependency>
            <groupId>com.fasterxml.jackson.core</groupId>
            <artifactId>jackson-databind</artifactId>
            <version>2.2.2</version>
        </dependency>  

Also use com.fasterxml.jackson.databind.JsonDeserializer and com.fasterxml.jackson.databind.annotation.JsonDeserialize for the deserialization and not the classes from org.codehaus.jackson

Here is a handy function you can use to help with identifying your opencv matrices at runtime. I find it useful for debugging, at least.

string type2str(int type) {
  string r;

  uchar depth = type & CV_MAT_DEPTH_MASK;
  uchar chans = 1 + (type >> CV_CN_SHIFT);

  switch ( depth ) {
    case CV_8U:  r = "8U"; break;
    case CV_8S:  r = "8S"; break;
    case CV_16U: r = "16U"; break;
    case CV_16S: r = "16S"; break;
    case CV_32S: r = "32S"; break;
    case CV_32F: r = "32F"; break;
    case CV_64F: r = "64F"; break;
    default:     r = "User"; break;
  }

  r += "C";
  r += (chans+'0');

  return r;
}

If M is a var of type Mat you can call it like so:

string ty =  type2str( M.type() );
printf("Matrix: %s %dx%d \n", ty.c_str(), M.cols, M.rows );

Will output data such as:

Matrix: 8UC3 640x480 
Matrix: 64FC1 3x2 

Its worth noting that there are also Matrix methods Mat::depth() and Mat::channels(). This function is just a handy way of getting a human readable interpretation from the combination of those two values whose bits are all stored in the same value.

For django forms you can do this;

form = UserLoginForm(data=request.POST) #getting the whole data from the user.
user = form.save() #saving the details obtained from the user.
username = user.cleaned_data.get("username") #where "username" in parenthesis is the name of the Charfield (the variale name i.e, username = forms.Charfield(max_length=64))

The @Nadun's version did not work for me, sizing wasn't working well. Removed the direction="column" or changing it to row, helps with building vertical login forms with responsive sizing.

<Grid
  container
  spacing={0}
  alignItems="center"
  justify="center"
  style={{ minHeight: "100vh" }}
>
  <Grid item xs={6}></Grid>
</Grid>;

You can use bubbling in your favor:

$('.foobar').on('click', function(e) {
    // do your thing.
}).on('click', 'div', function(e) {
    // clicked on descendant div
    e.stopPropagation();
});

Highcharts will automatically try to find the best format for the current zoom-range. This is done if the xAxis has the type 'datetime'. Next the unit of the current zoom is calculated, it could be one of:

• second
• minute
• hour
• day
• week
• month
• year

This unit is then used find a format for the axis labels. The default patterns are:

second: '%H:%M:%S',
minute: '%H:%M',
hour: '%H:%M',
day: '%e. %b',
week: '%e. %b',
month: '%b \'%y',
year: '%Y'

If you want the day to be part of the "hour"-level labels you should change the dateTimeLabelFormats option for that level include %d or %e. These are the available patters:

• %a: Short weekday, like 'Mon'.
• %A: Long weekday, like 'Monday'.
• %d: Two digit day of the month, 01 to 31.
• %e: Day of the month, 1 through 31.
• %b: Short month, like 'Jan'.
• %B: Long month, like 'January'.
• %m: Two digit month number, 01 through 12.
• %y: Two digits year, like 09 for 2009.
• %Y: Four digits year, like 2009.
• %H: Two digits hours in 24h format, 00 through 23.
• %I: Two digits hours in 12h format, 00 through 11.
• %l (Lower case L): Hours in 12h format, 1 through 11.
• %M: Two digits minutes, 00 through 59.
• %p: Upper case AM or PM.
• %P: Lower case AM or PM.
• %S: Two digits seconds, 00 through 59

You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.

This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:

I was facing the same issue when integrating Firebase Cloud Store in my project. Inside the project level gradle, I added

classpath 'com.google.gms:google-services:4.0.1'

that fixed the issue.

You can finish the Acivity and recreate it afterwards in this way your activity will be created again and all the views will be created with the new theme.

Below is the simplest way

Try the code

ALTER TRIGGER trigger_name DISABLE

That's it :)

if you are using ASP.NET MVC

Open the layout file "_Layout.cshtml" or your custom one

At the part of the code you see, as below:

@Scripts.Render("~/bundles/bootstrap")
@RenderSection("scripts", required: false)
@Scripts.Render("~/bundles/jquery")

Remove the line "@Scripts.Render("~/bundles/jquery")"

(at the part of the code you see) past as the latest line, as below:

@Styles.Render("~/Content/css")
@Scripts.Render("~/bundles/modernizr")
@Scripts.Render("~/bundles/jquery")

This help me and hope helps you as well.

Consider to use

git-rev-label

Gives information about Git repository revision in format like master-c73-gabc6bec. Can fill template string or file with environment variables and information from Git. Useful to provide information about version of the program: branch, tag, commit hash, commits count, dirty status, date and time. One of the most useful things is count of commits, not taking into account merged branches - only first parent.

yet another edit: As of version 5.2 pluck is not deprecated anymore, it just got new behaviour (same as lists previously - see side-note below):

edit: As of version 5.1 pluck is deprecated, so start using value instead:

DB::table('users')->where('username', $username)->value('groupName');    

// valid for L4 / L5.0 only
DB::table('users')->where('username', $username)->pluck('groupName');

this will return single value of groupName field of the first row found.

SIDE NOTE reg. @TomasButeler comment: As Laravel doesn't follow sensible versioning, there are sometimes cases like this. At the time of writing this answer we had pluck method to get SINGLE value from the query (Laravel 4.* & 5.0).

Then, with L5.1 pluck got deprecated and, instead, we got value method to replace it.

But to make it funny, pluck in fact was never gone. Instead it just got completely new behaviour and... deprecated lists method.. (L5.2) - that was caused by the inconsistency between Query Builder and Collection methods (in 5.1 pluck worked differently on the collection and query, that's the reason).

You can use MongoDB_DataObject wrapper to perform such query like below:

$model = new MongoDB_DataObject('orders');

$model->whereAdd('MONTH(created) = 4 AND YEAR(created) = 2016');

$model->find();

while ($model->fetch()) {
    var_dump($model);
}

OR, similarly, using direct query string:

$model = new MongoDB_DataObject();

$model->query('SELECT * FROM orders WHERE MONTH(created) = 4 AND YEAR(created) = 2016');

while ($model->fetch()) {
    var_dump($model);
}

You can use ObjectMapper.convertValue(), either value by value or even for the whole list. But you need to know the type to convert to:

POJO pojo = mapper.convertValue(singleObject, POJO.class);
// or:
List<POJO> pojos = mapper.convertValue(listOfObjects, new TypeReference<List<POJO>>() { });

this is functionally same as if you did:

byte[] json = mapper.writeValueAsBytes(singleObject);
POJO pojo = mapper.readValue(json, POJO.class);

but avoids actual serialization of data as JSON, instead using an in-memory event sequence as the intermediate step.

Use these:

• username : root
• password : (nothing)

Then you will get the page you want (more options than the admin page) with privileges.

While the results vary in this case because the column names are numbers, another way I've used is data.frame(rbind(mytable)). Using the example from @X.X:

> freq_t = table(cyl = mtcars$cyl, gear = mtcars$gear)

> freq_t
   gear
cyl  3  4  5
  4  1  8  2
  6  2  4  1
  8 12  0  2

> data.frame(rbind(freq_t))
  X3 X4 X5
4  1  8  2
6  2  4  1
8 12  0  2

If the column names do not start with numbers, the X won't get added to the front of them.

You have a problem one way or the other with your datetime.datetime.fromtimestamp(time.mktime(time.gmtime())) expression.

(1) If all you need is the difference between two instants in seconds, the very simple time.time() does the job.

(2) If you are using those timestamps for other purposes, you need to consider what you are doing, because the result has a big smell all over it:

gmtime() returns a time tuple in UTC but mktime() expects a time tuple in local time.

I'm in Melbourne, Australia where the standard TZ is UTC+10, but daylight saving is still in force until tomorrow morning so it's UTC+11. When I executed the following, it was 2011-04-02T20:31 local time here ... UTC was 2011-04-02T09:31

>>> import time, datetime
>>> t1 = time.gmtime()
>>> t2 = time.mktime(t1)
>>> t3 = datetime.datetime.fromtimestamp(t2)
>>> print t0
1301735358.78
>>> print t1
time.struct_time(tm_year=2011, tm_mon=4, tm_mday=2, tm_hour=9, tm_min=31, tm_sec=3, tm_wday=5, tm_yday=92, tm_isdst=0) ### this is UTC
>>> print t2
1301700663.0
>>> print t3
2011-04-02 10:31:03 ### this is UTC+1
>>> tt = time.time(); print tt
1301736663.88
>>> print datetime.datetime.now()
2011-04-02 20:31:03.882000 ### UTC+11, my local time
>>> print datetime.datetime(1970,1,1) + datetime.timedelta(seconds=tt)
2011-04-02 09:31:03.880000 ### UTC
>>> print time.localtime()
time.struct_time(tm_year=2011, tm_mon=4, tm_mday=2, tm_hour=20, tm_min=31, tm_sec=3, tm_wday=5, tm_yday=92, tm_isdst=1) ### UTC+11, my local time

You'll notice that t3, the result of your expression is UTC+1, which appears to be UTC + (my local DST difference) ... not very meaningful. You should consider using datetime.datetime.utcnow() which won't jump by an hour when DST goes on/off and may give you more precision than time.time()

Using Variable expansion/Substring replacement:

${var/%Pattern/Replacement}

If suffix of var matches Pattern, then substitute Replacement for Pattern.

So you can do:

~$ echo ${var/%????/}
some string

Alternatively,

If you have always the same 4 letters

~$ echo ${var/.rtf/}
some string

If it's always ending in .xyz:

~$ echo ${var%.*}
some string

You can also use the length of the string:

~$ len=${#var}
~$ echo ${var::len-4}
some string

or simply echo ${var::-4}

The major browser vendors differ on what "offline" means.

Chrome, Safari, and Firefox (since version 41) will detect when you go "offline" automatically - meaning that "online" events and properties will fire automatically when you unplug your network cable.

Mozilla Firefox (before version 41), Opera, and IE take a different approach, and consider you "online" unless you explicitly pick "Offline Mode" in the browser - even if you don't have a working network connection.

There are valid arguments for the Firefox/Mozilla behavior, which are outlined in the comments of this bug report:

https://bugzilla.mozilla.org/show_bug.cgi?id=654579

But, to answer the question - you can't rely on the online/offline events/property to detect if there is actually network connectivity.

Instead, you must use alternate approaches.

The "Notes" section of this Mozilla Developer article provides links to two alternate methods:

https://developer.mozilla.org/en/Online_and_offline_events

"If the API isn't implemented in the browser, you can use other signals to detect if you are offline including listening for AppCache error events and responses from XMLHttpRequest"

This links to an example of the "listening for AppCache error events" approach:

http://www.html5rocks.com/en/mobile/workingoffthegrid/#toc-appcache

...and an example of the "listening for XMLHttpRequest failures" approach:

http://www.html5rocks.com/en/mobile/workingoffthegrid/#toc-xml-http-request

HTH, -- Chad

You can get the element in JQuery by using its ID attribute like this:

$("#tcol1").hide();

Is it a good practice to use try-except-else in python?

The answer to this is that it is context dependent. If you do this:

d = dict()
try:
    item = d['item']
except KeyError:
    item = 'default'

It demonstrates that you don't know Python very well. This functionality is encapsulated in the dict.get method:

item = d.get('item', 'default')

The try/except block is a much more visually cluttered and verbose way of writing what can be efficiently executing in a single line with an atomic method. There are other cases where this is true.

However, that does not mean that we should avoid all exception handling. In some cases it is preferred to avoid race conditions. Don't check if a file exists, just attempt to open it, and catch the appropriate IOError. For the sake of simplicity and readability, try to encapsulate this or factor it out as apropos.

Read the Zen of Python, understanding that there are principles that are in tension, and be wary of dogma that relies too heavily on any one of the statements in it.

What does ** (double star) and * (star) do for parameters

They allow for functions to be defined to accept and for users to pass any number of arguments, positional (*) and keyword (**).

Defining Functions

*args allows for any number of optional positional arguments (parameters), which will be assigned to a tuple named args.

**kwargs allows for any number of optional keyword arguments (parameters), which will be in a dict named kwargs.

You can (and should) choose any appropriate name, but if the intention is for the arguments to be of non-specific semantics, args and kwargs are standard names.

Expansion, Passing any number of arguments

You can also use *args and **kwargs to pass in parameters from lists (or any iterable) and dicts (or any mapping), respectively.

The function recieving the parameters does not have to know that they are being expanded.

For example, Python 2's xrange does not explicitly expect *args, but since it takes 3 integers as arguments:

>>> x = xrange(3) # create our *args - an iterable of 3 integers
>>> xrange(*x)    # expand here
xrange(0, 2, 2)

As another example, we can use dict expansion in str.format:

>>> foo = 'FOO'
>>> bar = 'BAR'
>>> 'this is foo, {foo} and bar, {bar}'.format(**locals())
'this is foo, FOO and bar, BAR'

New in Python 3: Defining functions with keyword only arguments

You can have keyword only arguments after the *args - for example, here, kwarg2 must be given as a keyword argument - not positionally:

def foo(arg, kwarg=None, *args, kwarg2=None, **kwargs): 
    return arg, kwarg, args, kwarg2, kwargs

Usage:

>>> foo(1,2,3,4,5,kwarg2='kwarg2', bar='bar', baz='baz')
(1, 2, (3, 4, 5), 'kwarg2', {'bar': 'bar', 'baz': 'baz'})

Also, * can be used by itself to indicate that keyword only arguments follow, without allowing for unlimited positional arguments.

def foo(arg, kwarg=None, *, kwarg2=None, **kwargs): 
    return arg, kwarg, kwarg2, kwargs

Here, kwarg2 again must be an explicitly named, keyword argument:

>>> foo(1,2,kwarg2='kwarg2', foo='foo', bar='bar')
(1, 2, 'kwarg2', {'foo': 'foo', 'bar': 'bar'})

And we can no longer accept unlimited positional arguments because we don't have *args*:

>>> foo(1,2,3,4,5, kwarg2='kwarg2', foo='foo', bar='bar')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: foo() takes from 1 to 2 positional arguments 
    but 5 positional arguments (and 1 keyword-only argument) were given

Again, more simply, here we require kwarg to be given by name, not positionally:

def bar(*, kwarg=None): 
    return kwarg

In this example, we see that if we try to pass kwarg positionally, we get an error:

>>> bar('kwarg')
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bar() takes 0 positional arguments but 1 was given

We must explicitly pass the kwarg parameter as a keyword argument.

>>> bar(kwarg='kwarg')
'kwarg'

Python 2 compatible demos

*args (typically said "star-args") and **kwargs (stars can be implied by saying "kwargs", but be explicit with "double-star kwargs") are common idioms of Python for using the * and ** notation. These specific variable names aren't required (e.g. you could use *foos and **bars), but a departure from convention is likely to enrage your fellow Python coders.

We typically use these when we don't know what our function is going to receive or how many arguments we may be passing, and sometimes even when naming every variable separately would get very messy and redundant (but this is a case where usually explicit is better than implicit).

Example 1

The following function describes how they can be used, and demonstrates behavior. Note the named b argument will be consumed by the second positional argument before :

def foo(a, b=10, *args, **kwargs):
    '''
    this function takes required argument a, not required keyword argument b
    and any number of unknown positional arguments and keyword arguments after
    '''
    print('a is a required argument, and its value is {0}'.format(a))
    print('b not required, its default value is 10, actual value: {0}'.format(b))
    # we can inspect the unknown arguments we were passed:
    #  - args:
    print('args is of type {0} and length {1}'.format(type(args), len(args)))
    for arg in args:
        print('unknown arg: {0}'.format(arg))
    #  - kwargs:
    print('kwargs is of type {0} and length {1}'.format(type(kwargs),
                                                        len(kwargs)))
    for kw, arg in kwargs.items():
        print('unknown kwarg - kw: {0}, arg: {1}'.format(kw, arg))
    # But we don't have to know anything about them 
    # to pass them to other functions.
    print('Args or kwargs can be passed without knowing what they are.')
    # max can take two or more positional args: max(a, b, c...)
    print('e.g. max(a, b, *args) \n{0}'.format(
      max(a, b, *args))) 
    kweg = 'dict({0})'.format( # named args same as unknown kwargs
      ', '.join('{k}={v}'.format(k=k, v=v) 
                             for k, v in sorted(kwargs.items())))
    print('e.g. dict(**kwargs) (same as {kweg}) returns: \n{0}'.format(
      dict(**kwargs), kweg=kweg))

We can check the online help for the function's signature, with help(foo), which tells us

foo(a, b=10, *args, **kwargs)

Let's call this function with foo(1, 2, 3, 4, e=5, f=6, g=7)

which prints:

a is a required argument, and its value is 1
b not required, its default value is 10, actual value: 2
args is of type <type 'tuple'> and length 2
unknown arg: 3
unknown arg: 4
kwargs is of type <type 'dict'> and length 3
unknown kwarg - kw: e, arg: 5
unknown kwarg - kw: g, arg: 7
unknown kwarg - kw: f, arg: 6
Args or kwargs can be passed without knowing what they are.
e.g. max(a, b, *args) 
4
e.g. dict(**kwargs) (same as dict(e=5, f=6, g=7)) returns: 
{'e': 5, 'g': 7, 'f': 6}

Example 2

We can also call it using another function, into which we just provide a:

def bar(a):
    b, c, d, e, f = 2, 3, 4, 5, 6
    # dumping every local variable into foo as a keyword argument 
    # by expanding the locals dict:
    foo(**locals()) 

bar(100) prints:

a is a required argument, and its value is 100
b not required, its default value is 10, actual value: 2
args is of type <type 'tuple'> and length 0
kwargs is of type <type 'dict'> and length 4
unknown kwarg - kw: c, arg: 3
unknown kwarg - kw: e, arg: 5
unknown kwarg - kw: d, arg: 4
unknown kwarg - kw: f, arg: 6
Args or kwargs can be passed without knowing what they are.
e.g. max(a, b, *args) 
100
e.g. dict(**kwargs) (same as dict(c=3, d=4, e=5, f=6)) returns: 
{'c': 3, 'e': 5, 'd': 4, 'f': 6}

Example 3: practical usage in decorators

OK, so maybe we're not seeing the utility yet. So imagine you have several functions with redundant code before and/or after the differentiating code. The following named functions are just pseudo-code for illustrative purposes.

def foo(a, b, c, d=0, e=100):
    # imagine this is much more code than a simple function call
    preprocess() 
    differentiating_process_foo(a,b,c,d,e)
    # imagine this is much more code than a simple function call
    postprocess()

def bar(a, b, c=None, d=0, e=100, f=None):
    preprocess()
    differentiating_process_bar(a,b,c,d,e,f)
    postprocess()

def baz(a, b, c, d, e, f):
    ... and so on

We might be able to handle this differently, but we can certainly extract the redundancy with a decorator, and so our below example demonstrates how *args and **kwargs can be very useful:

def decorator(function):
    '''function to wrap other functions with a pre- and postprocess'''
    @functools.wraps(function) # applies module, name, and docstring to wrapper
    def wrapper(*args, **kwargs):
        # again, imagine this is complicated, but we only write it once!
        preprocess()
        function(*args, **kwargs)
        postprocess()
    return wrapper

And now every wrapped function can be written much more succinctly, as we've factored out the redundancy:

@decorator
def foo(a, b, c, d=0, e=100):
    differentiating_process_foo(a,b,c,d,e)

@decorator
def bar(a, b, c=None, d=0, e=100, f=None):
    differentiating_process_bar(a,b,c,d,e,f)

@decorator
def baz(a, b, c=None, d=0, e=100, f=None, g=None):
    differentiating_process_baz(a,b,c,d,e,f, g)

@decorator
def quux(a, b, c=None, d=0, e=100, f=None, g=None, h=None):
    differentiating_process_quux(a,b,c,d,e,f,g,h)

And by factoring out our code, which *args and **kwargs allows us to do, we reduce lines of code, improve readability and maintainability, and have sole canonical locations for the logic in our program. If we need to change any part of this structure, we have one place in which to make each change.

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.

I know this is an old question, but I am surprised that all answers ensure that the method exists and it is a function, when the OP does only want to check for existence. To know it is a function (as many have stated) you may use:

typeof myObj.prop2 === 'function'

But you may also use as a condition:

typeof myObj.prop2

Or even:

myObj.prop2

This is so because a function evaluates to true and undefined evaluates to false. So if you know that if the member exists it may only be a function, you can use:

if(myObj.prop2) {
  <we have prop2>
}

Or in an expression:

myObj.prop2 ? <exists computation> : <no prop2 computation>

If you don't need typesafe, just bring block to a new separated file and change the extension to .js,.jsx

you can try sklearn.metrics.classification_report as below:

import sklearn
y_true = [1, 1, 0, 0, 0, 1, 0, 1, 0, 0, 0]
y_pred = [1, 1, 1, 0, 0, 0, 1, 1, 0, 1, 0]

print sklearn.metrics.classification_report(y_true, y_pred)

output:

         precision    recall  f1-score   support

      0       0.80      0.57      0.67         7
      1       0.50      0.75      0.60         4

      avg / total       0.69      0.64      0.64        11

The easiest way to do this, is to install a JDK and tell Eclipse to use it as the default JRE. Use the default install.

(from memory)

Open Window -> Prefences. Select Installed Java runtimes, and choose Add. Navigate to root of your JDK (\Programs...\Java) and click Ok. Then select it to be the default JRE (checkmark).

After a workspace rebuild, you should have source attached to all JRE classes.

You cannot set height and width for elements with display:inline;. Use display:inline-block; instead.

From the CSS2 spec:

10.6.1 Inline, non-replaced elements

The height property does not apply. The height of the content area should be based on the font, but this specification does not specify how. A UA may, e.g., use the em-box or the maximum ascender and descender of the font. (The latter would ensure that glyphs with parts above or below the em-box still fall within the content area, but leads to differently sized boxes for different fonts; the former would ensure authors can control background styling relative to the 'line-height', but leads to glyphs painting outside their content area.)

EDIT — You're also missing a ; terminator for the height property:

<div style="display:inline; height:20px width: 70px">My Text Here</div>
<!--                                  ^^ here                       -->

Working example: http://jsfiddle.net/FpqtJ/

Below are some different ways to achieve this. Pick the one suits you

1. In fonts like 'Tahoma' and 'Times new Roman' this common password character '?' which is called 'Black circle' has a unicode value 0x25CF. Set the PasswordChar property with either the value 0x25CF or copy paste the actual character itself.

2. If you want to display the Black Circle by default then enable visual styles which should replace the default password character from '*' to '?' by default irrespective of the font.

3. Another alternative is to use 'Wingdings 2' font on the TextBox and set the password character to 0x97. This should work even if the application is not unicoded. Refer to charMap.exe to get better idea on different fonts and characters supported.

Let me assume that you have done the 'this' binding of 'sendThru' function.

The below functions clears the input fields when the method is triggered.

sendThru() {
    this.inputTitle.value = "";
    this.inputEntry.value = "";
}

Refs can be written as inline function expression:

ref={el => this.inputTitle = el}

where el refers to the component.

When refs are written like above, React sees a different function object each time so on every update, ref will be called with null immediately before it's called with the component instance.

Angular Component

A component is one of the basic building blocks of an Angular app. An app can have more than one component. In a normal app, a component contains an HTML view page class file, a class file that controls the behaviour of the HTML page and the CSS/scss file to style your HTML view. A component can be created using @Component decorator that is part of @angular/core module.

import { Component } from '@angular/core';

and to create a component

@Component({selector: 'greet', template: 'Hello {{name}}!'})
class Greet {
  name: string = 'World';
}

To create a component or angular app here is the tutorial

Angular Module

An angular module is set of angular basic building blocks like component, directives, services etc. An app can have more than one module.

A module can be created using @NgModule decorator.

@NgModule({
  imports:      [ BrowserModule ],
  declarations: [ AppComponent ],
  bootstrap:    [ AppComponent ]
})
export class AppModule { }

For the record, if you use Scala, you can do:

StringContext.treatEscapes(escaped)

I think it's possible in Java 9:

animalMap.entrySet().stream()
                .forEach(
                        pair -> Optional.ofNullable(pair.getValue())
                                .ifPresentOrElse(v -> myMap.put(pair.getKey(), v), v -> myList.add(pair.getKey())))
                );

Need the ifPresentOrElse for it to work though. (I think a for loop looks better.)

You cannot used the Helper @Html.DropdownListFor, because the first parameter was not correct, change your helper to:

@Html.DropDownList("accountid", new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))

@Html.DropDownListFor receive in the first parameters a lambda expression in all overloads and is used to create strongly typed dropdowns.

Here's the documentation

If your View it's strongly typed to some Model you may change your code using a helper to created a strongly typed dropdownlist, something like

@Html.DropDownListFor(x => x.accountId, new SelectList(ViewBag.Accounts, "AccountID", "AccountName"))

Use Regular expression to validate it.

isDate('2018-08-01T18:30:00.000Z');

isDate(_date){
        const _regExp  = new RegExp('^(-?(?:[1-9][0-9]*)?[0-9]{4})-(1[0-2]|0[1-9])-(3[01]|0[1-9]|[12][0-9])T(2[0-3]|[01][0-9]):([0-5][0-9]):([0-5][0-9])(.[0-9]+)?(Z)?$');
        return _regExp.test(_date);
    }

drop procedure if exists doWhile;
DELIMITER //  
CREATE PROCEDURE doWhile()   
BEGIN
DECLARE i INT DEFAULT 2376921001; 
WHILE (i <= 237692200) DO
    INSERT INTO `mytable` (code, active, total) values (i, 1, 1);
    SET i = i+1;
END WHILE;
END;
//  

CALL doWhile(); 

UPDATE

For security reasons, it is recommended to use sanitize instead of html_safe.

<%= sanitize @str %>

What's happening is that, as a security measure, Rails is escaping your string for you because it might have malicious code embedded in it. But if you tell Rails that your string is html_safe, it'll pass it right through.

@str = "<b>Hi</b>".html_safe
<%= @str %>

OR

@str = "<b>Hi</b>"
<%= @str.html_safe %>

Using raw works fine, but all it's doing is converting the string to a string, and then calling html_safe. When I know I have a string, I prefer calling html_safe directly, because it skips an unnecessary step and makes clearer what's going on. Details about string-escaping and XSS protection are in this Asciicast.

preg_replace shim with eval support

This is very inadvisable. But if you're not a programmer, or really prefer terrible code, you could use a substitute preg_replace function to keep your /e flag working temporarily.

/**
 * Can be used as a stopgap shim for preg_replace() calls with /e flag.
 * Is likely to fail for more complex string munging expressions. And
 * very obviously won't help with local-scope variable expressions.
 *
 * @license: CC-BY-*.*-comment-must-be-retained
 * @security: Provides `eval` support for replacement patterns. Which
 *   poses troubles for user-supplied input when paired with overly
 *   generic placeholders. This variant is only slightly stricter than
 *   the C implementation, but still susceptible to varexpression, quote
 *   breakouts and mundane exploits from unquoted capture placeholders.
 * @url: https://stackoverflow.com/q/15454220
 */
function preg_replace_eval($pattern, $replacement, $subject, $limit=-1) {
    # strip /e flag
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    # warn about most blatant misuses at least
    if (preg_match('/\(\.[+*]/', $pattern)) {
        trigger_error("preg_replace_eval(): regex contains (.*) or (.+) placeholders, which easily causes security issues for unconstrained/user input in the replacement expression. Transform your code to use preg_replace_callback() with a sane replacement callback!");
    }
    # run preg_replace with eval-callback
    return preg_replace_callback(
        $pattern,
        function ($matches) use ($replacement) {
            # substitute $1/$2/… with literals from $matches[]
            $repl = preg_replace_callback(
                '/(?<!\\\\)(?:[$]|\\\\)(\d+)/',
                function ($m) use ($matches) {
                    if (!isset($matches[$m[1]])) { trigger_error("No capture group for '$m[0]' eval placeholder"); }
                    return addcslashes($matches[$m[1]], '\"\'\`\$\\\0'); # additionally escapes '$' and backticks
                },
                $replacement
            );
            # run the replacement expression
            return eval("return $repl;");
        },
        $subject,
        $limit
    );
}

In essence, you just include that function in your codebase, and edit preg_replace to preg_replace_eval wherever the /e flag was used.

Pros and cons:

• Really just tested with a few samples from Stack Overflow.
• Does only support the easy cases (function calls, not variable lookups).
• Contains a few more restrictions and advisory notices.
• Will yield dislocated and less comprehensible errors for expression failures.
• However is still a usable temporary solution and doesn't complicate a proper transition to preg_replace_callback.
• And the license comment is just meant to deter people from overusing or spreading this too far.

Replacement code generator

Now this is somewhat redundant. But might help those users who are still overwhelmed with manually restructuring their code to preg_replace_callback. While this is effectively more time consuming, a code generator has less trouble to expand the /e replacement string into an expression. It's a very unremarkable conversion, but likely suffices for the most prevalent examples.

To use this function, edit any broken preg_replace call into preg_replace_eval_replacement and run it once. This will print out the according preg_replace_callback block to be used in its place.

/**
 * Use once to generate a crude preg_replace_callback() substitution. Might often
 * require additional changes in the `return …;` expression. You'll also have to
 * refit the variable names for input/output obviously.
 *
 * >>>  preg_replace_eval_replacement("/\w+/", 'strtopupper("$1")', $ignored);
 */
function preg_replace_eval_replacement($pattern, $replacement, $subjectvar="IGNORED") {
    $pattern = preg_replace('/(\W[a-df-z]*)e([a-df-z]*)$/i', '$1$2', $pattern);
    $replacement = preg_replace_callback('/[\'\"]?(?<!\\\\)(?:[$]|\\\\)(\d+)[\'\"]?/', function ($m) { return "\$m[{$m[1]}]"; }, $replacement);
    $ve = "var_export";
    $bt = debug_backtrace(0, 1)[0];
    print "<pre><code>
    #----------------------------------------------------
    # replace preg_*() call in '$bt[file]' line $bt[line] with:
    #----------------------------------------------------
    \$OUTPUT_VAR = preg_replace_callback(
        {$ve($pattern, TRUE)},
        function (\$m) {
            return {$replacement};
        },
        \$YOUR_INPUT_VARIABLE_GOES_HERE
    )
    #----------------------------------------------------
    </code></pre>\n";
}

Take in mind that mere copy&pasting is not programming. You'll have to adapt the generated code back to your actual input/output variable names, or usage context.

• Specificially the $OUTPUT = assignment would have to go if the previous preg_replace call was used in an if.
• It's best to keep temporary variables or the multiline code block structure though.

And the replacement expression may demand more readability improvements or rework.

• For instance stripslashes() often becomes redundant in literal expressions.
• Variable-scope lookups require a use or global reference for/within the callback.
• Unevenly quote-enclosed "-$1-$2" capture references will end up syntactically broken by the plain transformation into "-$m[1]-$m[2].

The code output is merely a starting point. And yes, this would have been more useful as an online tool. This code rewriting approach (edit, run, edit, edit) is somewhat impractical. Yet could be more approachable to those who are accustomed to task-centric coding (more steps, more uncoveries). So this alternative might curb a few more duplicate questions.

    var colors = new[]
    {
        new { value = Color.White, name = "White" },

        new { value = Color.Gray, name = "Gray" },
        new { value = Color.Black, name = "Black" },

        new { value = Color.Fuchsia, name = "Fuchsia" },
        new { value = Color.Purple, name = "Purple" }
    };
    foreach (var color in colors)
    {
        stackLayout.Children.Add(
            new Label
            {
                Text = color.name,
                TextColor = color.value,
            });
        FontSize = Device.GetNamedSize(NamedSize.Large, typeof(Label))
    }

this is a Tuple<Color, string>

_{Note: The question is about JavaScript, and this answer is about jQuery, which is wrong. This is an old answer, from times when jQuery was widespread.}

Instead, I recommend understanding scopes and closures in JavaScript.

Old, bad answer

With jQuery you can just do this, no matter where the declaration is:

$my_global_var = 'my value';

And will be available everywhere.

I use it for making quick image galleries, when images are spread in different places, like so:

$gallery = $('img');
$current = 0;

$gallery.each(function(i,v){
    // preload images
    (new Image()).src = v;
});
$('div').eq(0).append('<a style="display:inline-block" class="prev">prev</a> <div id="gallery"></div> <a style="display:inline-block" class="next">next</a>');
$('.next').click(function(){
    $current = ( $current == $gallery.length - 1 ) ? 0 : $current + 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});
$('.prev').click(function(){
    $current = ( $current == 0 ) ? $gallery.length - 1 : $current - 1;
    $('#gallery').hide().html($gallery[$current]).fadeIn();
});

Tip: run this whole code in the console in this page ;-)

It's not how they work. You "start" a marquee style progress bar by making it visible, you stop it by hiding it. You could change the Style property.

/**
 * Clones the provided array
 * 
 * @param src
 * @return a new clone of the provided array
 */
public static int[][] cloneArray(int[][] src) {
    int length = src.length;
    int[][] target = new int[length][src[0].length];
    for (int i = 0; i < length; i++) {
        System.arraycopy(src[i], 0, target[i], 0, src[i].length);
    }
    return target;
}

Is it possible to modify this code to support n-dimensional arrays of Objects?

You would need to support arbitrary lengths of arrays and check if the src and destination have the same dimensions, and you would also need to copy each element of each array recursively, in case the Object was also an array.

It's been a while since I posted this, but I found a nice example of one way to create an n-dimensional array class. The class takes zero or more integers in the constructor, specifying the respective size of each dimension. The class uses an underlying flat array Object[] and calculates the index of each element using the dimensions and an array of multipliers. (This is how arrays are done in the C programming language.)

Copying an instance of NDimensionalArray would be as easy as copying any other 2D array, though you need to assert that each NDimensionalArray object has equal dimensions. This is probably the easiest way to do it, since there is no recursion, and this makes representation and access much simpler.

Keep your common attributes together and assign specific (or override) attributes again.

/*  Headings */

Many C APIs use a null pointer to indicate "use the default", e.g. mosquittopp. Here is the pattern I am using, based on David Cormack's answer:

    mosqpp::tls_set(
        MqttOptions->CAFile.length() > 0 ? MqttOptions->CAFile.c_str() : NULL,
        MqttOptions->CAPath.length() > 0 ? MqttOptions->CAPath.c_str() : NULL,
        MqttOptions->CertFile.length() > 0 ? MqttOptions->CertFile.c_str() : NULL,
        MqttOptions->KeyFile.length() > 0 ? MqttOptions->KeyFile.c_str() : NULL
    );

It is a little cumbersome, but allows one to keep everything as a std::string up until the API call itself.

For Laravel >=6

composer require laravel/ui
php artisan ui vue --auth
php artisan migrate

Reference : Laravel Documentation for authentication

it looks you are not using Laravel 5.2, these are the available make commands in L5.2 and you are missing more than just the make:auth command

    make:auth           Scaffold basic login and registration views and routes
    make:console        Create a new Artisan command
    make:controller     Create a new controller class
    make:entity         Create a new entity.
    make:event          Create a new event class
    make:job            Create a new job class
    make:listener       Create a new event listener class
    make:middleware     Create a new middleware class
    make:migration      Create a new migration file
    make:model          Create a new Eloquent model class
    make:policy         Create a new policy class
    make:presenter      Create a new presenter.
    make:provider       Create a new service provider class
    make:repository     Create a new repository.
    make:request        Create a new form request class
    make:seeder         Create a new seeder class
    make:test           Create a new test class
    make:transformer    Create a new transformer.

Be sure you have this dependency in your composer.json file

    "laravel/framework": "5.2.*",

Then run

    composer update

I've read all the answers, the answers of similar questions and the complexity of the most "good" solutions didn't satisfy me. I don't want to put a huge round function set, or a small one but fails on scientific notation. So, I came up with this function. It may help someone in my situation:

function round(num, dec) {
   const [sv, ev] = num.toString().split('e');
   return Number(Number(Math.round(parseFloat(sv + 'e' + dec)) + 'e-' + dec) + 'e' + (ev || 0));
}

I didn't run any performance test because I will call this just to update the UI of my application. The function gives the following results for a quick test:

// 1/3563143 = 2.806510993243886e-7
round(1/3563143, 2)  // returns `2.81e-7`

round(1.31645, 4)    // returns 1.3165

round(-17.3954, 2)   // returns -17.4

This is enough for me.

In my case when i run select query it works and gives desired data. But when i run query like

select * from users where email = "[email protected]"

It shows this error

ERROR:  column "[email protected]" does not exist
LINE 2: select * from users where email = "[email protected]...
                                          ^
SQL state: 42703
Character: 106

Then i use single quotes instead of double quotes for match condition, it works. for ex.

select * from users where email = '[email protected]'

The benefit of WireShark is that it could possibly show you errors in levels below the HTTP protocol. Fiddler will show you errors in the HTTP protocol.

If you think the problem is somewhere in the HTTP request issued by the browser, or you are just looking for more information in regards to what the server is responding with, or how long it is taking to respond, Fiddler should do.

If you suspect something may be wrong in the TCP/IP protocol used by your browser and the server (or in other layers below that), go with WireShark.

'How to be a Programmer: A Short, Comprehensive, and Personal Summary' by Robert L Read

Not exactly a book but an essay, but this one was definitely an inspiration for me when I got into coding. Loved the notion of entering a tribe. Worth a read.

You can use Google Cloud Messaging or GCM, it's free and easy to use. Also you can use third party push servers like PushWoosh which gives you more flexibility

Use the FROM_UNIXTIME() function in MySQL

Remember that if you are using a framework that stores it in milliseconds (for example Java's timestamp) you have to divide by 1000 to obtain the right Unix time in seconds.

Just an improvement to the nice answer given by @vuhung3990. I implemented the solution and works great but if I touch one radio button it will be selected and nothing happens.

I suggest to also change page when a radio button is tapped. To do this, simply add a listener to the radioGroup:

mPager = (ViewPager) findViewById(R.id.pager);
final RadioGroup radioGroup = (RadioGroup)findViewById(R.id.radiogroup);    
radioGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() {
            @Override
            public void onCheckedChanged(RadioGroup group, int checkedId) {
                switch (checkedId) {
                    case R.id.radioButton :
                        mPager.setCurrentItem(0, true);
                        break;
                    case R.id.radioButton2 :
                        mPager.setCurrentItem(1, true);
                        break;
                    case R.id.radioButton3 :
                        mPager.setCurrentItem(2, true);
                        break;
                }
            }
        });

That data:image/png;base64 URL is cool, I’ve never run into it before. The long encrypted link is the actual image, i.e. no image call to the server. See RFC 2397 for details.

Side note: I have had trouble getting larger base64 images to render on IE8. I believe IE8 has a 32K limit that can be problematic for larger files. See this other StackOverflow thread for details.

I think what you are looking for is as follows.

cars_by_cylinders_gears <- mtcars %>%
  group_by(cyl, gear) %>%
  summarise(count = n())

This is using the dplyr package. This is essentially the longhand version of the count () solution provided by docendo discimus.

You can absolutely position pseudo elements relative to their parent element.

This gives you two extra layers to play with for every element - so positioning one image on top of another becomes easy - with minimal and semantic markup (no empty divs etc).

markup:

<div class="overlap"></div>

css:

.overlap
{
    width: 100px;
    height: 100px;
    position: relative;
    background-color: blue;
}
.overlap:after
{
    content: '';
    position: absolute;
    width: 20px;
    height: 20px;
    top: 5px;
    left: 5px;
    background-color: red;
}

For intellij 13, Simply change the Project language level itself to 8.0 with following navigation.

File
|
|
 ---------Project Structure -> Project tab
          |
          |________Project language level

Module lang level

I also had to update Modules lang level when there was no maven plugin for java compiler.

File
|
|
 ---------Project Structure -> Modules tab
          |
          |________ language level

But this Module lang level would automatically be fixed if there's already a maven plugin for it,

    <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-compiler-plugin</artifactId>
        <version>3.6.0</version>
        <configuration>
            <source>1.8</source>
            <target>1.8</target>
        </configuration>
    </plugin>

After changes everything looks good

svn add --force * --auto-props --parents --depth infinity -q

Great tip! One remark: my Eclipse adds new files to the ignore list automatically. It may be a matter of configuration, but anyhow: there is the --no-ignore option that helps.

After this, you can commit:

svn commit -m 'Adding a file'

You are confusing quantmod's 'symbol' (a term relating to a code for some financial thingamuwot) with R's 'symbol', which is a 'type' in R.

You've said:

I have a character vector of stock symbols that I pass to quantmod::getSymbols() and the function returns the symbol to the environment without the quotes

Well almost. What it does is create objects with those names in the specified environment. What I think you want to do is to get things out of an environment by name. And for that you need 'get'. Here's how, example code, working in the default environment:

getSymbols('F',src='yahoo',return.class='ts') [1] "F"

so you have a vector of characters of the things you want:

> z="F"
> z
[1] "F"

and then the magic:

> summary(get(z))
     F.Open           F.High           F.Low           F.Close      
 Min.   : 1.310   Min.   : 1.550   Min.   : 1.010   Min.   : 1.260  
 1st Qu.: 5.895   1st Qu.: 6.020   1st Qu.: 5.705   1st Qu.: 5.885  
 Median : 7.950   Median : 8.030   Median : 7.800   Median : 7.920  
 Mean   : 8.358   Mean   : 8.495   Mean   : 8.178   Mean   : 8.332  
 3rd Qu.:11.210   3rd Qu.:11.400   3rd Qu.:11.000   3rd Qu.:11.180  
 Max.   :18.810   Max.   :18.970   Max.   :18.610   Max.   :18.790  

and if you don't believe me:

> identical(F,get(z))

Matplotlib doesn't work with pixels directly, but rather physical sizes and DPI. If you want to display a figure with a certain pixel size, you need to know the DPI of your monitor. For example this link will detect that for you.

If you have an image of 3841x7195 pixels it is unlikely that you monitor will be that large, so you won't be able to show a figure of that size (matplotlib requires the figure to fit in the screen, if you ask for a size too large it will shrink to the screen size). Let's imagine you want an 800x800 pixel image just for an example. Here's how to show an 800x800 pixel image in my monitor (my_dpi=96):

plt.figure(figsize=(800/my_dpi, 800/my_dpi), dpi=my_dpi)

So you basically just divide the dimensions in inches by your DPI.

If you want to save a figure of a specific size, then it is a different matter. Screen DPIs are not so important anymore (unless you ask for a figure that won't fit in the screen). Using the same example of the 800x800 pixel figure, we can save it in different resolutions using the dpi keyword of savefig. To save it in the same resolution as the screen just use the same dpi:

plt.savefig('my_fig.png', dpi=my_dpi)

To to save it as an 8000x8000 pixel image, use a dpi 10 times larger:

plt.savefig('my_fig.png', dpi=my_dpi * 10)

Note that the setting of the DPI is not supported by all backends. Here, the PNG backend is used, but the pdf and ps backends will implement the size differently. Also, changing the DPI and sizes will also affect things like fontsize. A larger DPI will keep the same relative sizes of fonts and elements, but if you want smaller fonts for a larger figure you need to increase the physical size instead of the DPI.

Getting back to your example, if you want to save a image with 3841 x 7195 pixels, you could do the following:

plt.figure(figsize=(3.841, 7.195), dpi=100)
( your code ...)
plt.savefig('myfig.png', dpi=1000)

Note that I used the figure dpi of 100 to fit in most screens, but saved with dpi=1000 to achieve the required resolution. In my system this produces a png with 3840x7190 pixels -- it seems that the DPI saved is always 0.02 pixels/inch smaller than the selected value, which will have a (small) effect on large image sizes. Some more discussion of this here.

You have to loop through the array, no other way to check all elements. Just one correction for the code - if all elements are negative, maxValue will be 0 at the end. You should initialize it with the minimum possible value for integer.
And if you are going to search the array many times it's a good idea to sort it first, than searching is faster (binary search) and minimum and maximum elements are just the first and the last.

CGRectOffset has since been replaced with the instance method offsetBy.

https://developer.apple.com/reference/coregraphics/cgrect/1454841-offsetby

For example, what used to be

aView.frame = CGRectOffset(aView.frame, 10, 10)

would now be

aView.frame = aView.frame.offsetBy(dx: CGFloat(10), dy: CGFloat(10))

Doesn't look like you are using the correct overload of ActionLink. Try this:-

<%=Html.ActionLink("Modify Villa", "Modify", new {id = "1"})%>

This assumes your view is under the /Views/Villa folder. If not then I suspect you need:-

<%=Html.ActionLink("Modify Villa", "Modify", "Villa", new {id = "1"}, null)%>

The route engine uses the same sequence as you add rules into it. Once it gets the first matched rule, it will stop checking other rules and take this to search for controller and action.

So, you should:

1. Put your specific rules ahead of your general rules(like default), which means use RouteTable.Routes.MapHttpRoute to map "WithActionApi" first, then "DefaultApi".

2. Remove the defaults: new { id = System.Web.Http.RouteParameter.Optional } parameter of your "WithActionApi" rule because once id is optional, url like "/api/{part1}/{part2}" will never goes into "DefaultApi".

3. Add an named action to your "DefaultApi" to tell the route engine which action to enter. Otherwise once you have more than one actions in your controller, the engine won't know which one to use and throws "Multiple actions were found that match the request: ...". Then to make it matches your Get method, use an ActionNameAttribute.

So your route should like this:

// Map this rule first
RouteTable.Routes.MapRoute(
     "WithActionApi",
     "api/{controller}/{action}/{id}"
 );

RouteTable.Routes.MapRoute(
    "DefaultApi",
    "api/{controller}/{id}",
    new { action="DefaultAction", id = System.Web.Http.RouteParameter.Optional }
);

And your controller:

[ActionName("DefaultAction")] //Map Action and you can name your method with any text
public string Get(int id)
{
    return "object of id id";
}        

[HttpGet]
public IEnumerable<string> ByCategoryId(int id)
{
    return new string[] { "byCategory1", "byCategory2" };
}

Some parenthesis are missing.

Change

 window.location.href = "/comments.aspx?id=" + movieShareId.textContent || movieShareId.innerText + "/";

to

 window.location = "/comments.aspx?id=" + (movieShareId.textContent || movieShareId.innerText) + "/";

No priority is given to the || compared to the +.

Remove also everything after the window.location assignation : this code isn't supposed to be executed as the page changes.

Note: you don't need to set location.href. It's enough to just set location.

Use css:

<style>
input[name=btnsubmit]:active {
color: green;
}
</style>

If there is no existing method then I guess you can iterate from 0 to input.size()/2, taking each consecutive element and appending it to a new ArrayList.

EDIT: Actually, I think you can take that List and use it to instantiate a new ArrayList using one of the ArrayList constructors.

Flexbox (http://caniuse.com/#feat=flexbox)

First wrap the columns you want in a div or section, ex:

<div class="content">
    <div class="main"></div>
    <div class="sidebar"></div>
</div>

Then add the following CSS:

.content {
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;
    display: flex;
}

From the accepted answer, it looks like your desired behaviour is to turn

If that's right, then I think something like

import csv

with open("test.dat", "rb") as infile, open("test.csv", "wb") as outfile:
    reader = csv.reader(infile)
    writer = csv.writer(outfile, quoting=False)
    for i, line in enumerate(reader):
        if i < 4: continue
        date = line[0].split()
        day = date[0].split('-')
        time = date[1].split(':')
        newline = day + time + line[1:]
        writer.writerow(newline)

would be a little simpler than the reps stuff.

1. Press Ctrl+H (Replace)

2. Select Extended from SearchMode

3. Put \r\n\r\n in Find What

4. Put \r\n in ReplaceWith

5. Click on Replace All

This can be done using request.args.get(). For example if your query string has a field date, it can be accessed using

date = request.args.get('date')

Don't forget to add "request" to list of imports from flask, i.e.

from flask import request

For use in Kotlin inside fragment, which is a common use case it is very easy with KeyboardVisibilityEvent library.

In build.gradle:

implementation 'net.yslibrary.keyboardvisibilityevent:keyboardvisibilityevent:3.0.0-RC2'

In Fragment:

activity?.let {
    KeyboardVisibilityEvent.setEventListener(it,object: KeyboardVisibilityEventListener {
        override fun onVisibilityChanged(isOpen: Boolean) {
            if (isOpen) Toast.makeText(context,"Keyboard is opened",Toast.LENGTH_SHORT).show()

The jQuery blog, jQuery 3.1.1 Released!, says,

Slim build

Sometimes you don’t need ajax, or you prefer to use one of the many standalone libraries that focus on ajax requests. And often it is simpler to use a combination of CSS and class manipulation for all your web animations. Along with the regular version of jQuery that includes the ajax and effects modules, we’ve released a “slim” version that excludes these modules. All in all, it excludes ajax, effects, and currently deprecated code. The size of jQuery is very rarely a load performance concern these days, but the slim build is about 6k gzipped bytes smaller than the regular version – 23.6k vs 30k.

Just for the record, here is the difference between If and IIf:

IIf(condition, true-part, false-part):

• This is the old VB6/VBA Function
• The function always returns an Object type, so if you want to use the methods or properties of the chosen object, you have to re-cast it with DirectCast or CType or the Convert.* Functions to its original type
• Because of this, if true-part and false-part are of different types there is no matter, the result is just an object anyway

If(condition, true-part, false-part):

• This is the new VB.NET Function
• The result type is the type of the chosen part, true-part or false-part
• This doesn't work, if Strict Mode is switched on and the two parts are of different types. In Strict Mode they have to be of the same type, otherwise you will get an Exception
• If you really need to have two parts of different types, switch off Strict Mode (or use IIf)
• I didn't try so far if Strict Mode allows objects of different type but inherited from the same base or implementing the same Interface. The Microsoft documentation isn't quite helpful about this issue. Maybe somebody here knows it.

Here's an example that lists all tags of all images on the registry. It handles a registry configured for HTTP Basic auth too.

THE_REGISTRY=localhost:5000

# Get username:password from docker configuration. You could
# inject these some other way instead if you wanted.
CREDS=$(jq -r ".[\"auths\"][\"$THE_REGISTRY\"][\"auth\"]" .docker/config.json | base64 -d)

curl -s --user $CREDS https://$THE_REGISTRY/v2/_catalog | \
    jq -r '.["repositories"][]' | \
    xargs -I @REPO@ curl -s --user $CREDS https://$THE_REGISTRY/v2/@REPO@/tags/list | \
    jq -M '.["name"] + ":" + .["tags"][]'

Explanation:

• extract username:password from .docker/config.json
• make a https request to the registry to list all "repositories"
• filter the json result to a flat list of repository names
• for each repository name:
• make a https request to the registry to list all "tags" for that "repository"
• filter the stream of result json objects, printing "repository":"tag" pairs for each tag found in each repository

More actual solution:

<a id="someId">Link</a>

const a = document.querySelector('#someId');
a.href = 'url';

Actually, the absolutely easiest way is to do the following...

byte[] content = your_byte[];

FileContentResult result = new FileContentResult(content, "application/octet-stream") 
{
  FileDownloadName = "your_file_name"
};

return result;

Many right answers but in case you want it in a float, directly, without using regex:

x= '$123.45M'

float(''.join(c for c in x if (c.isdigit() or c =='.'))

123.45

You can change the point for a comma depending on your needs.

change for this if you know your number is an integer

x='$1123'    
int(''.join(c for c in x if c.isdigit())

1123

If you want your variables to be valid for all tests, you can have an application.properties file in your test resources directory (by default: src/test/resources) which will look something like this:

MYPROPERTY=foo

This will then be loaded and used unless you have definitions via @TestPropertySource or a similar method - the exact order in which properties are loaded can be found in the Spring documentation chapter 24. Externalized Configuration.

HEAD is not the latest revision, it's the current revision. Usually, it's the latest revision of the current branch, but it doesn't have to be.

master is a name commonly given to the main branch, but it could be called anything else (or there could be no main branch).

origin is a name commonly given to the main remote. remote is another repository that you can pull from and push to. Usually it's on some server, like github.

Here is my bash script

docker build -t ${IMAGE}:${VERSION} .
docker tag ${IMAGE}:${VERSION} ${IMAGE}:latest

You can then remove untagged images if you rebuilt the same version with

docker rmi $(docker images | grep "^<none>" | awk "{print $3}")

or

docker rmi $(docker images | grep "^<none>" | tr -s " " | cut -d' ' -f3 | tr '\n' ' ')

or

Clean up commands:

Docker 1.13 introduces clean-up commands. To remove all unused containers, images, networks and volumes:

docker system prune

or individually:

docker container prune
docker image prune
docker network prune
docker volume prune

Looks like this bug has been around for quite a while! Here are some bug references you may find helpful (and may want to subscribe to / vote up, hint, hint...):

Debian bug #85123 ("sudo: SECURE_PATH still can't be overridden") (from 2001!)

It seems that Bug#20996 is still present in this version of sudo. The changelog says that it can be overridden at runtime but I haven't yet discovered how.

They mention putting something like this in your sudoers file:

Defaults secure_path="/bin:/usr/bin:/usr/local/bin"

but when I do that in Ubuntu 8.10 at least, it gives me this error:

visudo: unknown defaults entry `secure_path' referenced near line 10

Ubuntu bug #50797 ("sudo built with --with-secure-path is problematic")

Worse still, as far as I can tell, it is impossible to respecify secure_path in the sudoers file. So if, for example, you want to offer your users easy access to something under /opt, you must recompile sudo.

---

Yes. There needs to be a way to override this "feature" without having to recompile. Nothing worse then security bigots telling you what's best for your environment and then not giving you a way to turn it off.

---

This is really annoying. It might be wise to keep current behavior by default for security reasons, but there should be a way of overriding it other than recompiling from source code! Many people ARE in need of PATH inheritance. I wonder why no maintainers look into it, which seems easy to come up with an acceptable solution.

---

I worked around it like this:

mv /usr/bin/sudo /usr/bin/sudo.orig

then create a file /usr/bin/sudo containing the following:

#!/bin/bash
/usr/bin/sudo.orig env PATH=$PATH "$@"

then your regular sudo works just like the non secure-path sudo

Ubuntu bug #192651 ("sudo path is always reset")

Given that a duplicate of this bug was originally filed in July 2006, I'm not clear how long an ineffectual env_keep has been in operation. Whatever the merits of forcing users to employ tricks such as that listed above, surely the man pages for sudo and sudoers should reflect the fact that options to modify the PATH are effectively redundant.

Modifying documentation to reflect actual execution is non destabilising and very helpful.

Ubuntu bug #226595 ("impossible to retain/specify PATH")

I need to be able to run sudo with additional non-std binary folders in the PATH. Having already added my requirements to /etc/environment I was surprised when I got errors about missing commands when running them under sudo.....

I tried the following to fix this without sucess:

1. Using the "sudo -E" option - did not work. My existing PATH was still reset by sudo

2. Changing "Defaults env_reset" to "Defaults !env_reset" in /etc/sudoers -- also did not work (even when combined with sudo -E)

3. Uncommenting env_reset (e.g. "#Defaults env_reset") in /etc/sudoers -- also did not work.

4. Adding 'Defaults env_keep += "PATH"' to /etc/sudoers -- also did not work.

Clearly - despite the man documentation - sudo is completely hardcoded regarding PATH and does not allow any flexibility regarding retaining the users PATH. Very annoying as I can't run non-default software under root permissions using sudo.

$(document).ready(function() {
    window.setInterval(function() {
    var timeLeft    = $("#timeLeft").html();
        if(eval(timeLeft) == 0) {
                window.location= ("http://www.technicalkeeda.com");
        } else {
            $("#timeLeft").html(eval(timeLeft)- eval(1));
        }
    }, 1000);
});

Try this formula

=SMALL((A1,C1,E1),INDEX(FREQUENCY((A1,C1,E1),0),1)+1)

Both SMALL and FREQUENCY functions accept "unions" as arguments, i.e. single cell references separated by commas and enclosed in brackets like (A1,C1,E1).

So the formula uses FREQUENCY and INDEX to find the number of zeroes in a range and if you add 1 to that you get the k value such that the kth smallest is always the minimum value excluding zero.

I'm assuming you don't have negative numbers.....

You could also check out the "Data Scripter Add-In" for SQL Server Management Studio 2008 from:

http://www.mssql-vehicle-data.com/SSMS

Their features list:

• It was developed on SSMS 2008 and is not supported on the 2005 version at this time (soon!)

• Export data quickly to T-SQL for MSSQL and MySQL syntax

• CSV, TXT, XML are also supported! Harness the full potential, power, and speed that SQL has to offer.

• Don't wait for Access or Excel to do scripting work for you that could take several minutes to do -- let SQL Server do it for you and take all the guess work out of exporting your data!

• Customize your data output for rapid backups, DDL manipulation, and more...

• Change table names and database schemas to your needs, quickly and efficiently

• Export column names or simply generate data without the names.

• You can chose individual columns to script.

• You can chose sub-sets of data (WHERE clause).

• You can chose ordering of data (ORDER BY clause).

• Great backup utility for those grungy database debugging operations that require data manipulation. Don't lose data while experimenting. Manipulate data on the fly!

if grep -q SomeString "$File"; then
  Some Actions # SomeString was found
fi

You don't need [[ ]] here. Just run the command directly. Add -q option when you don't need the string displayed when it was found.

The grep command returns 0 or 1 in the exit code depending on the result of search. 0 if something was found; 1 otherwise.

$ echo hello | grep hi ; echo $?
1
$ echo hello | grep he ; echo $?
hello
0
$ echo hello | grep -q he ; echo $?
0

You can specify commands as an condition of if. If the command returns 0 in its exitcode that means that the condition is true; otherwise false.

$ if /bin/true; then echo that is true; fi
that is true
$ if /bin/false; then echo that is true; fi
$

As you can see you run here the programs directly. No additional [] or [[]].

Additionally, if you have restricted access to the database (IE: Can't use "Script Function as > CREATE To"), there is another option to get this query.

Find your View > right click > "Design".

This will give you the query you are looking for.

Missing prerequisites. IBM has the solution below:

yum install gtk2.i686
yum install libXtst.i686

If you received the the missing libstdc++ message above, 
install the libstdc++ library:

In addition to the above explanations, what I experience:

app.use('/book', handler);  

will match all requests beginning with '/book' as URL. so it also matches '/book/1' or '/book/2'

app.get('/book')  

matches only GET request with exact match. It will not handle URLs like '/book/1' or '/book/2'

So, if you want a global handler that handles all of your routes, then app.use('/') is the option. app.get('/') will handle only the root URL.

actions in Vuex are asynchronous. The only way to let the calling function (initiator of action) to know that an action is complete - is by returning a Promise and resolving it later.

Here is an example: myAction returns a Promise, makes a http call and resolves or rejects the Promise later - all asynchronously

actions: {
    myAction(context, data) {
        return new Promise((resolve, reject) => {
            // Do something here... lets say, a http call using vue-resource
            this.$http("/api/something").then(response => {
                // http success, call the mutator and change something in state
                resolve(response);  // Let the calling function know that http is done. You may send some data back
            }, error => {
                // http failed, let the calling function know that action did not work out
                reject(error);
            })
        })
    }
}

Now, when your Vue component initiates myAction, it will get this Promise object and can know whether it succeeded or not. Here is some sample code for the Vue component:

export default {
    mounted: function() {
        // This component just got created. Lets fetch some data here using an action
        this.$store.dispatch("myAction").then(response => {
            console.log("Got some data, now lets show something in this component")
        }, error => {
            console.error("Got nothing from server. Prompt user to check internet connection and try again")
        })
    }
}

As you can see above, it is highly beneficial for actions to return a Promise. Otherwise there is no way for the action initiator to know what is happening and when things are stable enough to show something on the user interface.

And a last note regarding mutators - as you rightly pointed out, they are synchronous. They change stuff in the state, and are usually called from actions. There is no need to mix Promises with mutators, as the actions handle that part.

Edit: My views on the Vuex cycle of uni-directional data flow:

If you access data like this.$store.state["your data key"] in your components, then the data flow is uni-directional.

The promise from action is only to let the component know that action is complete.

The component may either take data from promise resolve function in the above example (not uni-directional, therefore not recommended), or directly from $store.state["your data key"] which is unidirectional and follows the vuex data lifecycle.

The above paragraph assumes your mutator uses Vue.set(state, "your data key", http_data), once the http call is completed in your action.

I think it's asking you to do this:

SELECT ID
FROM (SELECT ID,
             msisdn 
      FROM (SELECT * FROM TT2) as myalias
     ) as anotheralias;

But why would you write this query in the first place?

Surprised no one had mentioned yet the new built in libraries:

You can use the option command:

option(USE_CLANG "build application with clang" OFF) # OFF is the default

and then wrap the clang-compiler settings in if()s:

if(USE_CLANG)
    SET (...)
    ....
endif(USE_CLANG)

This way it is displayed as an cmake option in the gui-configuration tools.

To make it systemwide you can of course use an environment variable as the default value or stay with Ferruccio's answer.

I'd just like to point out something in these answers. In a date/time format string, '/' will be replaced with whatever the user's date separator is, and ':' will be replaced with whatever the user's time separator is. That is, if I've defined my date separator to be '.' (in the Regional and Language Options control panel applet, "intl.cpl"), and my time separator to be '?' (just pretend I'm crazy like that), then

DateTime.Now.ToString("MM/dd/yyyy h:mm tt")

would return

01.05.2009 6?01 PM

In most cases, this is what you want, because you want to respect the user's settings. If, however, you require the format be something specific (say, if it's going to parsed back out by somebody else down the wire), then you need to escape these special characters:

DateTime.Now.ToString("MM\\/dd\\/yyyy h\\:mm tt")

or

DateTime.Now.ToString(@"MM\/dd\/yyyy h\:mm tt")

which would now return

01/05/2009 6:01 PM

EDIT:

Then again, if you really want to respect the user's settings, you should use one of the standard date/time format strings, so that you respect not only the user's choices of separators, but also the general format of the date and/or time.

DateTime.Now.ToShortDateString()
DateTime.Now.ToString("d")

Both would return "1/5/2009" using standard US options, or "05/01/2009" using standard UK options, for instance.

DateTime.Now.ToLongDateString()
DateTime.Now.ToString("D")

Both would return "Monday, January 05, 2009" in US locale, or "05 January 2009" in UK.

DateTime.Now.ToShortTimeString()
DateTime.Now.ToString("t");

"6:01 PM" in US, "18:01" in UK.

DateTime.Now.ToLongTimeString()
DateTime.Now.ToString("T");

"6:01:04 PM" in US, "18:01:04" in UK.

DateTime.Now.ToString()
DateTime.Now.ToString("G");

"1/5/2009 6:01:04 PM" in US, "05/01/2009 18:01:04" in UK.

Many other options are available. See docs for standard date and time format strings and custom date and time format strings.

You have to use cin.getline():

char input[100];
cin.getline(input,sizeof(input));

SELECT COALESCE(IF(myColumn = 1,COUNT(DISTINCT NumberColumn),NULL),0) column1,
COALESCE(CASE WHEN myColumn = 1 THEN COUNT(DISTINCT NumberColumn) ELSE NULL END,0) AS column2
FROM AD_CurrentView

The script below is a generic solution that works for me. It is based on ideas pulled from this and other threads.

When a link with an href attribute beginning with "#" is clicked, it scrolls the page smoothly to the indicated div. Where only the "#" is present, it scrolls smoothly to the top of the page.

$('a[href^=#]').click(function(){
    event.preventDefault();
    var target = $(this).attr('href');
    if (target == '#')
      $('html, body').animate({scrollTop : 0}, 600);
    else
      $('html, body').animate({
        scrollTop: $(target).offset().top - 100
    }, 600);
});

For example, When the code above is present, clicking a link with the tag <a href="#"> scrolls to the top of the page at speed 600. Clicking a link with the tag <a href="#mydiv"> scrolls to 100px above <div id="mydiv"> at speed 600. Feel free to change these numbers.

I hope it helps!

The best place to demystify this is the source code. The docs are woefully inadequate about explaining this.

dispatchTouchEvent is actually defined on Activity, View and ViewGroup. Think of it as a controller which decides how to route the touch events.

For example, the simplest case is that of View.dispatchTouchEvent which will route the touch event to either OnTouchListener.onTouch if it's defined or to the extension method onTouchEvent.

For ViewGroup.dispatchTouchEvent things are way more complicated. It needs to figure out which one of its child views should get the event (by calling child.dispatchTouchEvent). This is basically a hit testing algorithm where you figure out which child view's bounding rectangle contains the touch point coordinates.

But before it can dispatch the event to the appropriate child view, the parent can spy and/or intercept the event all together. This is what onInterceptTouchEvent is there for. So it calls this method first before doing the hit testing and if the event was hijacked (by returning true from onInterceptTouchEvent) it sends a ACTION_CANCEL to the child views so they can abandon their touch event processing (from previous touch events) and from then onwards all touch events at the parent level are dispatched to onTouchListener.onTouch (if defined) or onTouchEvent(). Also in that case, onInterceptTouchEvent is never called again.

Would you even want to override [Activity|ViewGroup|View].dispatchTouchEvent? Unless you are doing some custom routing you probably should not.

The main extension methods are ViewGroup.onInterceptTouchEvent if you want to spy and/or intercept touch event at the parent level and View.onTouchListener/View.onTouchEvent for main event handling.

All in all its overly complicated design imo but android apis lean more towards flexibility than simplicity.

I used Dapper to bypass this constraint of Entity framework Core.

IDbConnection.Query

is working with either sql query or stored procedure with multiple parameters. By the way it's a bit faster (see benchmark tests )

Dapper is easy to learn. It took 15 minutes to write and run stored procedure with parameters. Anyway you may use both EF and Dapper. Below is an example:

 public class PodborsByParametersService
{
    string _connectionString = null;


    public PodborsByParametersService(string connStr)
    {
        this._connectionString = connStr;

    }

    public IList<TyreSearchResult> GetTyres(TyresPodborView pb,bool isPartner,string partnerId ,int pointId)
    {

        string sqltext  "spGetTyresPartnerToClient";

        var p = new DynamicParameters();
        p.Add("@PartnerID", partnerId);
        p.Add("@PartnerPointID", pointId);

        using (IDbConnection db = new SqlConnection(_connectionString))
        {
            return db.Query<TyreSearchResult>(sqltext, p,null,true,null,CommandType.StoredProcedure).ToList();
        }


        }
}

Try this:

$(document).ready( function () {
  $('#example').dataTable({
    "order": []
  });
});

this will solve your problem.

return JsonConvert.SerializeObject(images.ToList(), Formatting.None, new JsonSerializerSettings { PreserveReferencesHandling = PreserveReferencesHandling.None, ReferenceLoopHandling = ReferenceLoopHandling.Ignore });

Assuming that your button is in a form, you are not preventing the default behaviour of the button click from happening i.e. Your AJAX call is made in addition to the form submission; what you're very likely seeing is one of

1. the form submission happens faster than the AJAX call returns
2. the form submission causes the browser to abort the AJAX request and continues with submitting the form.

So you should prevent the default behaviour of the button click

$('#btnSave').click(function (e) {

    // prevent the default event behaviour    
    e.preventDefault();

    $.ajax({
        url: "/Home/SaveDetailedInfo",
        type: "POST",
        data: JSON.stringify({ 'Options': someData}),
        dataType: "json",
        traditional: true,
        contentType: "application/json; charset=utf-8",
        success: function (data) {

            // perform your save call here

            if (data.status == "Success") {
                alert("Done");
            } else {
                alert("Error occurs on the Database level!");
            }
        },
        error: function () {
            alert("An error has occured!!!");
        }
    });
});

Instead of exceptions, just use:

if (Build.VERSION.SDK_INT >= 11)

and use

@SuppressLint("NewApi")

to suppress the warnings.

As others have said, Objective-C is much more dynamic in terms of how it thinks of objects vs. C++'s fairly static realm.

Objective-C, being in the Smalltalk lineage of object-oriented languages, has a concept of objects that is very similar to that of Java, Python, and other "standard", non-C++ object-oriented languages. Lots of dynamic dispatch, no operator overloading, send messages around.

C++ is its own weird animal; it mostly skipped the Smalltalk portion of the family tree. In some ways, it has a good module system with support for inheritance that happens to be able to be used for object-oriented programming. Things are much more static (overridable methods are not the default, for example).
