I use this:

public class ReversedView<E> extends AbstractList<E>{

    public static <E> List<E> of(List<E> list) {
        return new ReversedView<>(list);
    }

    private final List<E> backingList;

    private ReversedView(List<E> backingList){
        this.backingList = backingList;
    }

    @Override
    public E get(int i) {
        return backingList.get(backingList.size()-i-1);
    }

    @Override
    public int size() {
        return backingList.size();
    }

}

like this:

ReversedView.of(backingList) // is a fully-fledged generic (but read-only) list

Use getChildCount() and getChildAt(int index).

Example:

LinearLayout ll = …
final int childCount = ll.getChildCount();
for (int i = 0; i < childCount; i++) {
      View v = ll.getChildAt(i);
      // Do something with v.
      // …
}

This one worked for me. using the srcset. I have just learnt about it so i dont know if browsers support it but it has worked for me. Try it and later give me your feed back.

There are probably less than 20 entries in your xml.

change the code to this

for ($i=0;$i< sizeof($xml->entry); $i++)

To edit bashrc in Ubuntu

$ /usr/bin/vim ~/.bashrc

type PATH=$PATH:$HOME/anaconda3/bin Press Esc and :wq to save bashrc file and exit vim enter image description here

then

$ export PATH=~/anaconda3/bin:$PATH

and type $ source ~/.bashrc Now to confirm the installation of conda type

$ conda --version

The default generator for Windows seems to be set to NMAKE. Try to use:

cmake -G "MinGW Makefiles"

Or use the GUI, and select MinGW Makefiles when prompted for a generator. Don't forget to cleanup the directory where you tried to run CMake, or delete the cache in the GUI. Otherwise, it will try again with NMAKE.

This will work:

override func viewDidLoad() {
    super.viewDidLoad()
    // Swift block syntax (iOS 10+)
    let timer = Timer(timeInterval: 0.4, repeats: true) { _ in print("Done!") }
    // Swift >=3 selector syntax
    let timer = Timer.scheduledTimer(timeInterval: 0.4, target: self, selector: #selector(self.update), userInfo: nil, repeats: true)
    // Swift 2.2 selector syntax
    let timer = NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: #selector(MyClass.update), userInfo: nil, repeats: true)
    // Swift <2.2 selector syntax
    let timer = NSTimer.scheduledTimerWithTimeInterval(0.4, target: self, selector: "update", userInfo: nil, repeats: true)
}

// must be internal or public. 
@objc func update() {
    // Something cool
}

For Swift 4, the method of which you want to get the selector must be exposed to Objective-C, thus @objc attribute must be added to the method declaration.

The simplest solution is to select the second cell, and press =. This will begin the fomula creation process. Now either type in the 1st cell reference (eg, A1) or click on the first cell and press enter. This should make the second cell reference the value of the first cell.

To read up more on different options for referencing see - This Article.

It should be like:

    public static void calculateTime(long seconds) {
            int day = (int)TimeUnit.SECONDS.toDays(seconds);        
            long hours = TimeUnit.SECONDS.toHours(seconds) - (day *24);
            long minute = TimeUnit.SECONDS.toMinutes(seconds) - (TimeUnit.SECONDS.toHours(seconds)* 60);
            long second = TimeUnit.SECONDS.toSeconds(seconds) - (TimeUnit.SECONDS.toMinutes(seconds) *60);

            System.out.println("Day " + day + " Hour " + hours + " Minute " + minute + " Seconds " + second);

        }

Explanation:

TimeUnit.SECONDS.toHours(seconds) will give you direct conversion from seconds to hours with out consideration for days. Minus the hours for days you already got i.e, day*24. You now got remaining hours. Same for minute and second. You need to minus the already got hour and minutes respectively.

I am seeing this error message when I run Firefox headless through selenium using xvfb. It turns out that the message was a red herring for me. The message is only a warning, not an error. It is not why Firefox was not starting correctly.

The reason that Firefox was not starting for me was that it had been updated to a version that was no longer compatible with the Selenium drivers that I was using. I upgraded the selenium drivers to the latest and Firefox starts up fine again (even with this warning message about RANDR).

New releases of Firefox are often only compatible with one or two versions of Selenium. Occasionally Firefox is released with NO compatible version of Selenium. When that happens, it may take a week or two for a new version of Selenium to get released. Because of this, I now keep a version of Firefox that is known to work with the version of Selenium that I have installed. In addition to the version of Firefox that is kept up to date by my package manager, I have a version installed in /opt/ (eg /opt/firefox31/). The Selenium Java API takes an argument for the location of the Firefox binary to be used. The downside is that older versions of Firefox have known security vulnerabilities and shouldn't be used with untrusted content.

Your method's return value has to be a List<Project>.

Using select new you are creating an instance of an anonymous type, instead of a Project.

I had the same issue and tried all the options (delete schema, delete specific row, update checksum) but nothing works.

In my case flyway-core dependency got corrupted somehow.

Solution:

1. Delete flyway-core folder from ~.m2\local repository path...\org\flywaydb\flyway-core.

2. Execute "maven clean install" so that it will download new one and add it into a project.

I hope this will help.

Prefer composition over inheritance as it is more malleable / easy to modify later, but do not use a compose-always approach. With composition, it's easy to change behavior on the fly with Dependency Injection / Setters. Inheritance is more rigid as most languages do not allow you to derive from more than one type. So the goose is more or less cooked once you derive from TypeA.

My acid test for the above is:

• Does TypeB want to expose the complete interface (all public methods no less) of TypeA such that TypeB can be used where TypeA is expected? Indicates Inheritance.

  • e.g. A Cessna biplane will expose the complete interface of an airplane, if not more. So that makes it fit to derive from Airplane.

• Does TypeB want only some/part of the behavior exposed by TypeA? Indicates need for Composition.

  • e.g. A Bird may need only the fly behavior of an Airplane. In this case, it makes sense to extract it out as an interface / class / both and make it a member of both classes.

Update: Just came back to my answer and it seems now that it is incomplete without a specific mention of Barbara Liskov's Liskov Substitution Principle as a test for 'Should I be inheriting from this type?'

There are a few ways to do this.

The first is the most widely used. It works on all major browsers.

input[readonly] {
 background-color: #dddddd;
}

While the one above will select all inputs with readonly attached, this one below will select only what you desire. Make sure to replace demo with whatever input type you want.

input[type="demo"]:read-only {
 background-color: #dddddd;
}

This is an alternate to the first, but it's not used a whole lot:

input:read-only {
 background-color: #dddddd;
}

The :read-only selector is supported in Chrome, Opera, and Safari. Firefox uses :-moz-read-only. IE doesn't support the :read-only selector.

You can also use input[readonly="readonly"], but this is pretty much the same as input[readonly], from my experience.

In my case, I messed up the connectionString property in a publish profile, trying to access the wrong database (Initial Catalog). Entity Framework then complains that the entities do not match the database, and rightly so.

At line 5 there is a / missing.

There is a good answer on the differences between ; and / here.

Basically, when running a CREATE block via script, you need to use / to let SQLPlus know when the block ends, since a PL/SQL block can contain many instances of ;.

I read an article a while ago that talked about locking down every class as much as possible. Make everything final and private unless you have an immediate need to expose some data or functionality to the outside world. It's always easy to expand the scope to be more permissible later on, but not the other way around. First consider making as many things as possible final which will make choosing between private and protected much easier.

1. Make all classes final unless you need to subclass them right away.
2. Make all methods final unless you need to subclass and override them right away.
3. Make all method parameters final unless you need to change them within the body of the method, which is kinda awkward most of the times anyways.

Now if you're left with a final class, then make everything private unless something is absolutely needed by the world - make that public.

If you're left with a class that does have subclass(es), then carefully examine every property and method. First consider if you even want to expose that property/method to subclasses. If you do, then consider whether a subclass can wreak havoc on your object if it messed up the property value or method implementation in the process of overriding. If it's possible, and you want to protect your class' property/method even from subclasses (sounds ironic, I know), then make it private. Otherwise make it protected.

Disclaimer: I don't program much in Java :)

For me after installing windows-build-tools with the below comment

npm --add-python-to-path='true' --debug install --global windows-build-tools

running the code below

npm config set python "%USERPROFILE%\.windows-build-tools\python27\python.exe"

has worked.

I think what you want is something like:

=INDEX(B:B,MATCH(C2,A:A,0))  

I should mention that MATCH checks the position at which the value can be found within A:A (given the 0, or FALSE, parameter, it looks only for an exact match and given its nature, only the first instance found) then INDEX returns the value at that position within B:B.

Here is an example to explain the most simple way of using getter and setter in java. One can do this in a more straightforward way but getter and setter have something special that is when using private member of parent class in child class in inheritance. You can make it possible through using getter and setter.

package stackoverflow;

    public class StackoverFlow 

    {

        private int x;

        public int getX()
        {
            return x;
        }

        public int setX(int x)
        {
          return  this.x = x;
        }
         public void showX()
         {
             System.out.println("value of x  "+x);
         }


        public static void main(String[] args) {

            StackoverFlow sto = new StackoverFlow();
            sto.setX(10);
            sto.getX();
            sto.showX();
        }

    }

Also note that ($) is the identity function specialised to function types. The identity function looks like this:

id :: a -> a
id x = x

While ($) looks like this:

($) :: (a -> b) -> (a -> b)
($) = id

Note that I've intentionally added extra parentheses in the type signature.

Uses of ($) can usually be eliminated by adding parenthesis (unless the operator is used in a section). E.g.: f $ g x becomes f (g x).

Uses of (.) are often slightly harder to replace; they usually need a lambda or the introduction of an explicit function parameter. For example:

f = g . h

becomes

f x = (g . h) x

becomes

f x = g (h x)

Hope this helps!

On Ubuntu; using mkvirtualenv -p python3 env_name loads the virtualenv with python3.

Inside the env, use python --version to verify.

1) First Insert JS file path in an index.html file :

<script src="assets/video.js" type="text/javascript"></script>

2) Import JS file and declare the variable in component.ts :

• import './../../../assets/video.js';

• declare var RunPlayer: any;

  NOTE: Variable name should be same as the name of a function in js file

3) Call the js method in the component

ngAfterViewInit(){

    setTimeout(() => {
        new RunPlayer();
    });

}

As mentioned in Django docs, when get method finds no entry or finds multiple entries, it raises an exception, this is the expected behavior:

get() raises MultipleObjectsReturned if more than one object was found. The MultipleObjectsReturned exception is an attribute of the model class.

get() raises a DoesNotExist exception if an object wasn’t found for the given parameters. This exception is an attribute of the model class.

Using exceptions is a way to handle this problem, but I actually don't like the ugly try-except block. An alternative solution, and cleaner to me, is to use the combination of filter + first.

user = UniversityDetails.objects.filter(email=email).first()

When you do .first() to an empty queryset it returns None. This way you can have the same effect in a single line.

The only difference between catching the exception and using this method occurs when you have multiple entries, the former will raise an exception while the latter will set the first element, but as you are using get I may assume we won't fall on this situation.

Note that first method was added on Django 1.6.

The error vanished after I did Clean->Run xDoclet->Run xPackaging.

I tested this for version 2.4 of artifact org.codehaus.mojo and that worked ~

This is good in the general case:

yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries)

There is no empty element in the returned array if the path itself ends in a (back)slash (e.g. "\foo\bar\"). However, you will have to be sure that yourPath is really a directory and not a file. You can find out what it is and compensate if it is a file like this:

if(Directory.Exists(yourPath)) {
  var entries = yourPath.Split(@"\/", StringSplitOptions.RemoveEmptyEntries);
}
else if(File.Exists(yourPath)) {
  var entries = Path.GetDirectoryName(yourPath).Split(
                    @"\/", StringSplitOptions.RemoveEmptyEntries);
}
else {
  // error handling
}

I believe this covers all bases without being too pedantic. It will return a string[] that you can iterate over with foreach to get each directory in turn.

If you want to use constants instead of the @"\/" magic string, you need to use

var separators = new char[] {
  Path.DirectorySeparatorChar,  
  Path.AltDirectorySeparatorChar  
};

and then use separators instead of @"\/" in the code above. Personally, I find this too verbose and would most likely not do it.

Yet another solution: Export every GO* environment variable from go env

.bashrc:

eval $(go env | grep '^GO[A-Z0-9_]*=' | while read setenv; do
  echo "export $setenv; "
done 2> /dev/null)

[[ -n $GOPATH ]] || export GOPATH="$HOME/go/bin"
[[ -n $GOROOT ]] || export GOROOT=/usr/bin/go
export PATH="$PATH:$GOPATH/bin:$GOROOT/bin"

I found this on another forum. Works like a champ.

InputFilter filter = new InputFilter() {
    public CharSequence filter(CharSequence source, int start, int end,
            Spanned dest, int dstart, int dend) {
        for (int i = start; i < end; i++) {
            if (!Character.isLetterOrDigit(source.charAt(i))) {
                return "";
            }
        }
        return null;
    }
};
edit.setFilters(new InputFilter[] { filter });

Recently I found the most clean and easy to understand way of dealing with it:

$(document).on 'ready page:load', ->
  # Actions to do

OR

$(document).on('ready page:load', function () {
  // Actions to do
});

EDIT
If you have delegated events bound to the document, make sure you attach them outside of the ready function, otherwise they will get rebound on every page:load event (causing the same functions to be run multiple times). For example, if you have any calls like this:

$(document).on 'ready page:load', ->
  ...
  $(document).on 'click', '.button', ->
    ...
  ...

Take them out of the ready function, like this:

$(document).on 'ready page:load', ->
  ...
  ...

$(document).on 'click', '.button', ->
  ...

Delegated events bound to the document do not need to be bound on the ready event.

There is a plugin to check if an element is focused: http://plugins.jquery.com/project/focused

$('input').each(function(){
   if ($(this) == $.focused()) {
      $(this).addClass('focused');
   }
})

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {res.EMAIL, res.USERNAME} );

OR you can use

 var employee =  (from res in _db.EMPLOYEEs
 where (res.EMAIL == givenInfo || res.USER_NAME == givenInfo)
 select new {email=res.EMAIL, username=res.USERNAME} );

Explanation :

1. Select employee from the db as res.

2. Filter the employee details as per the where condition.

3. Select required fields from the employee object by creating an Anonymous object using new { }

I was trying to do this and found that, using the answers above, when using Functions.identity() for the key to the Map, then I had issues with using a local method like this::localMethodName to actually work because of typing issues.

Functions.identity() actually does something to the typing in this case so the method would only work by returning Object and accepting a param of Object

To solve this, I ended up ditching Functions.identity() and using s->s instead.

So my code, in my case to list all directories inside a directory, and for each one use the name of the directory as the key to the map and then call a method with the directory name and return a collection of items, looks like:

Map<String, Collection<ItemType>> items = Arrays.stream(itemFilesDir.listFiles(File::isDirectory))
.map(File::getName)
.collect(Collectors.toMap(s->s, this::retrieveBrandItems));

You can try something like this

r = requests.get(ENDPOINT, params=params, headers={'Authorization': 'Basic %s' %  API_KEY})

If you have both date and time information in the numeric value, then use as.POSIXct. Data.table package IDateTime format is such a case. If you use fwrite to save a file, the package automatically converts date-times to idatetime format which is unix time. To convert back to normal format following can be done.

Example: Let's say you have a unix time stamp with date and time info: 1442866615

> as.POSIXct(1442866615,origin="1970-01-01")
[1] "2015-09-21 16:16:54 EDT"

I used String.prototype.match(regex) which returns a string array of all found matches of the given regex in the string (more info see here):

function getLastIndex(text, regex, limit = text.length) {_x000D_
  const matches = text.match(regex);_x000D_
_x000D_
  // no matches found_x000D_
  if (!matches) {_x000D_
    return -1;_x000D_
  }_x000D_
_x000D_
  // matches found but first index greater than limit_x000D_
  if (text.indexOf(matches[0] + matches[0].length) > limit) {_x000D_
    return -1;_x000D_
  }_x000D_
_x000D_
  // reduce index until smaller than limit_x000D_
  let i = matches.length - 1;_x000D_
  let index = text.lastIndexOf(matches[i]);_x000D_
  while (index > limit && i >= 0) {_x000D_
    i--;_x000D_
    index = text.lastIndexOf(matches[i]);_x000D_
  }_x000D_
  return index > limit ? -1 : index;_x000D_
}_x000D_
_x000D_
// expect -1 as first index === 14_x000D_
console.log(getLastIndex('First Sentence. Last Sentence. Unfinished', /\. /g, 10));_x000D_
_x000D_
// expect 29_x000D_
console.log(getLastIndex('First Sentence. Last Sentence. Unfinished', /\. /g));

you need to specify the min and target sdk version in the manifest file.
If not the android.permission.READ_PHONE_STATE will be added automaticly while exporting your apk file.

<uses-sdk
        android:minSdkVersion="9"
        android:targetSdkVersion="19" />

Actually, the accepted answer is unnecessarily complicated.

If you set the label to AutoSize, it will automatically grow with whatever text you put in it. (This includes vertical growth.)

If you want to make it word wrap at a particular width, you can set the MaximumSize property.

myLabel.MaximumSize = new Size(100, 0);
myLabel.AutoSize = true;

Tested and works.

create new DefaultCellEditor class :

public static class Editor_name extends DefaultCellEditor {
  public Editor_name(JCheckBox checkBox) {
   super(checkBox);
  }
  @Override
  public boolean isCellEditable(EventObject anEvent) {
    return false;
  }
}

and use setCellEditor :

JTable table = new JTable();
table.getColumn("columnName").setCellEditor(new Editor_name(new JCheckBox()));

Did you try Processas mentioned here: http://msdn.microsoft.com/de-de/library/system.diagnostics.process.aspx?

You could use

Process myProcess = new Process();

try
{
    // true is the default, but it is important not to set it to false
    myProcess.StartInfo.UseShellExecute = true; 
    myProcess.StartInfo.FileName = "http://some.domain.tld/bla";
    myProcess.Start();
}
catch (Exception e)
{
    Console.WriteLine(e.Message);
}

Arrays.sort(numArray);
int middle = ((numArray.length) / 2);
if(numArray.length % 2 == 0){
 int medianA = numArray[middle];
 int medianB = numArray[middle-1];
 median = (medianA + medianB) / 2;
} else{
 median = numArray[middle + 1];
}

EDIT: I initially had medianB setting to middle+1 in the even length arrays, this was wrong due to arrays starting count at 0. I have updated it to use middle-1 which is correct and should work properly for an array with an even length.

You can use the Below codes for shifting not rotating:

    int []arr = {1,2,3,4,5,6,7,8,9,10,11,12};
            int n = arr.length;
            int d = 3;

Programm for shifting array of size n by d elements towards left:

    Input : {1,2,3,4,5,6,7,8,9,10,11,12}
    Output: {4,5,6,7,8,9,10,11,12,10,11,12}

        public void shiftLeft(int []arr,int d,int n) {
            for(int i=0;i<n-d;i++) {
                arr[i] = arr[i+d];
            }
        }

Programm for shifting array of size n by d elements towards right:

    Input : {1,2,3,4,5,6,7,8,9,10,11,12}
    Output: {1,2,3,1,2,3,4,5,6,7,8,9}

        public void shiftRight(int []arr,int d,int n) {

            for(int i=n-1;i>=d;i--) {
                arr[i] = arr[i-d];
            }
        }

While this doesn't actually answer your question, I'd go about this in a different way.

Simply clear the remote_image field after successfully saving the local copy. Then in your save method you can always update the image whenever remote_image isn't empty.

If you'd like to keep a reference to the url, you could use an non-editable boolean field to handle the caching flag rather than remote_image field itself.

My worry is if I say delete evertything with an ID (>79 AND < 296) then it may literally wipe the whole table...

That wont happen because you will have a where clause. What happens is that, if you have a statement like delete * from Table1 where id between 70 and 1296 , the first thing that sql query processor will do is to scan the table and look for those records in that range and then apply a delete.

You can also search the DOM using ClassName. For example:

document.getElementsByClassName("myDiv")

This will return an array. If there is one particular property you are interested in. For example:

var divWidth = document.getElementsByClassName("myDiv")[0].clientWidth;

divWidth will now be equal to the the width of the first element in your div array.

So I follow first answer, but my vnc viewer gives me grey screen when I connect to it. And I found this Ask Ubuntu link to solve that.

The only difference with previous answer is you need to install these extra packages:

apt-get install gnome-panel gnome-settings-daemon metacity nautilus gnome-terminal

And use this ~/.vnc/xstartup file:

#!/bin/sh

export XKL_XMODMAP_DISABLE=1
unset SESSION_MANAGER
unset DBUS_SESSION_BUS_ADDRESS

[ -x /etc/vnc/xstartup ] && exec /etc/vnc/xstartup
[ -r $HOME/.Xresources ] && xrdb $HOME/.Xresources

On my Ubuntu VM, with 1048 MB total RAM, java -XX:+PrintFlagsFinal -version | grep HeapSize printed : uintx MaxHeapSize := 266338304, which is approx 266MB and is 1/4th of my total RAM.

If you have multiple rows for parent_id.

SELECT GROUP_CONCAT(id) FROM table_level where parent_id=4 GROUP BY parent_id;

If you want to replace space with comma.

SELECT REPLACE(id,' ',',') FROM table_level where parent_id=4;

This error you are receiving :

SQLSTATE[HY093]: Invalid parameter number: parameter was not defined

is because the number of elements in $values & $matches is not the same or $matches contains more than 1 element.

If $matches contains more than 1 element, than the insert will fail, because there is only 1 column name referenced in the query(hash)

If $values & $matches do not contain the same number of elements then the insert will also fail, due to the query expecting x params but it is receiving y data $matches.

I believe you will also need to ensure the column hash has a unique index on it as well.

Try the code here:

<?php

/*** mysql hostname ***/
$hostname = 'localhost';

/*** mysql username ***/
$username = 'root';

/*** mysql password ***/
$password = '';

try {
    $dbh = new PDO("mysql:host=$hostname;dbname=test", $username, $password);
    /*** echo a message saying we have connected ***/
    echo 'Connected to database';
    }
catch(PDOException $e)
    {
    echo $e->getMessage();
    }


$matches = array('1');
$count = count($matches);
for($i = 0; $i < $count; ++$i) {
    $values[] = '?';
}

// INSERT INTO DATABASE
$sql = "INSERT INTO hashes (hash) VALUES (" . implode(', ', $values) . ") ON DUPLICATE KEY UPDATE hash='hash'";
$stmt = $dbh->prepare($sql);
$data = $stmt->execute($matches);

//Error reporting if something went wrong...
var_dump($dbh->errorInfo());

?>

You will need to adapt it a little.

Table structure I used is here:

CREATE TABLE IF NOT EXISTS `hashes` (
  `hashid` int(11) NOT NULL AUTO_INCREMENT,
  `hash` varchar(250) NOT NULL,
  PRIMARY KEY (`hashid`),
  UNIQUE KEY `hash1` (`hash`)
) ENGINE=InnoDB  DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;

Code was run on my XAMPP Server which is using PHP 5.3.8 with MySQL 5.5.16.

I hope this helps.

In Spring boot: 2.1.6, you can use like below:

    @GetMapping("/orders")
    @ApiOperation(value = "retrieve orders", response = OrderResponse.class, responseContainer = "List")
    public List<OrderResponse> getOrders(
            @RequestParam(value = "creationDateTimeFrom", required = true) String creationDateTimeFrom,
            @RequestParam(value = "creationDateTimeTo", required = true) String creationDateTimeTo,
            @RequestParam(value = "location_id", required = true) String location_id) {

        // TODO...

        return response;

@ApiOperation is an annotation that comes from Swagger api, It is used for documenting the apis.

Simply set form "Accept Button" Property to button that you want to hit by Enter key. Or in load event write this.acceptbutton = btnName;

I created a library to address the need for a page indicator in a ViewPager. My library contains a View called DotIndicator. To use my library, add compile 'com.matthew-tamlin:sliding-intro-screen:3.2.0' to your gradle build file.

The View can be added to your layout by adding the following:

    <com.matthewtamlin.sliding_intro_screen_library.indicators.DotIndicator
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:numberOfDots=YOUR_INT_HERE
            app:selectedDotIndex=YOUR_INT_HERE/>

The above code perfectly replicates the functionality of the dots on the Google Launcher homescreen, however if you want to further customise it then the following attributes can be added:

• app:unselectedDotDiameter and app:selectedDotDiameter to set the diameters of the dots
• app:unselectedDotColor and app:selectedDotColor to set the colors of the dots
• app:spacingBetweenDots to change the distance between the dots
• app:dotTransitionDuration to set the time for animating the change from small to big (and back)

Additionally, the view can be created programatically using:

DotIndicator indicator = new DotIndicator(context);

Methods exist to modify the properties, similar to the attributes. To update the indicator to show a different page as selected, just call method indicator.setSelectedItem(int, true) from inside ViewPager.OnPageChangeListener.onPageSelected(int).

Here's an example of it in use:

If you're interested, the library was actually designed to make intro screens like the one shown in the above gif.

Github source available here: https://github.com/MatthewTamlin/SlidingIntroScreen

Try:

num3 = 100000000000LL;

And BTW, in C++ this is a compiler extension, the standard does not define long long, thats part of C99.

Here's a simple solution, using TypeScript:

  convertDateStringToDate(dateStr) {
    //  Convert a string like '2020-10-04T00:00:00' into '4/Oct/2020'
    let months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
    let date = new Date(dateStr);
    let str = date.getDate()
                + '/' + months[date.getMonth()]
                + '/' + date.getFullYear()
    return str;
  }

(Yeah, I know the question was about JavaScript, but I'm sure I won't be the only Angular developer coming across this article !)

Your constructor may (later, in an extension of your software) be called from the constructor of a subclass that overrides the virtual method. Now not the subclass's implementation of the function, but the implementation of the base class will be called. So it doesn't really make sense to call a virtual function here.

However, if your design satisfies the Liskov Substitution principle, no harm will be done. Probably that's why it's tolerated - a warning, not an error.

For some reason, the lib is present while compiling, but missing while running.

My situation is, two versions of one lib conflict.

For example, A depends on B and C, while B depends on D:1.0, C depends on D:1.1, maven may just import D:1.0. If A uses one class which is in D:1.1 but not in D:1.0, a NoClassDefFoundError will be throwed.

If you are in this situation too, you need to resolve the dependency conflict.

Java has a class specifically for zip files and one even more specifically for Jar Files.

java.util.jar.JarOutputStream
java.util.jar.JarInputStream

using those you could, on a command from the console, using a scanner set to system.in

Scanner console = new Scanner(System.in);
String input = console.nextLine();

then get all the components and write them as a file.

JarEntry JE = null;
while((JE = getNextJarEntry()) != null)
{
    //do stuff with JE
}

You can also use java.util.zip.ZipInputStream instead, as seeing a JAR file is in the same format as a ZIP file, ZipInputStream will be able to handle the Jar file, in fact JarInputStream actually extends ZipInputStream.

an alternative is also instead of getNextJarEntry, to use getNextEntry

With Joda-Time

DateTime dt = new DateTime();
DateTime added = dt.plusHours(6);

You can use the Bean Comparator to sort on any property in your custom class.

In Ruby, the Windows version anyways, I just checked and __FILE__ does not contain the full path to the file. Instead it contains the path to the file relative to where it's being executed from.

In PHP __FILE__ is the full path (which in my opinion is preferable). This is why, in order to make your paths portable in Ruby, you really need to use this:

File.expand_path(File.dirname(__FILE__) + "relative/path/to/file")

I should note that in Ruby 1.9.1 __FILE__ contains the full path to the file, the above description was for when I used Ruby 1.8.7.

In order to be compatible with both Ruby 1.8.7 and 1.9.1 (not sure about 1.9) you should require files by using the construct I showed above.

Short of using a local templating system like many hundreds now exist in every scripting language or even using your homebrewed one with sed or m4 and sending the result over to your server, no, you'd need at least SSI.

You do not embed the images in the bundle. They are called through the browser. So its;

var imgSrc = './image/image1.jpg';

return <img src={imgSrc} />

Would like to thank you for some excellent replies. @AR., your a star and it works perfectly. I had noticed last night that the Excel.exe was not closing; so I did some research and found out about how to release the COM objects. Here is my final code:

using System;
using System.Collections.Generic;
using System.Text;
using System.Reflection;
using System.IO;
using Excel;

namespace testExcelconsoleApp
{
    class Program
    {
        private String fileLoc = @"C:\temp\test.xls";

        static void Main(string[] args)
        {
            Program p = new Program();
            p.createExcel();
        }

        private void createExcel()
        {
            Excel.Application excelApp = null;
            Excel.Workbook workbook = null;
            Excel.Sheets sheets = null;
            Excel.Worksheet newSheet = null;

            try
            {
                FileInfo file = new FileInfo(fileLoc);
                if (file.Exists)
                {
                    excelApp = new Excel.Application();
                    workbook = excelApp.Workbooks.Open(fileLoc, 0, false, 5, "", "",
                                                        false, XlPlatform.xlWindows, "",
                                                        true, false, 0, true, false, false);

                    sheets = workbook.Sheets;

                    //check columns exist
                    foreach (Excel.Worksheet sheet in sheets)
                    {
                        Console.WriteLine(sheet.Name);
                        sheet.Select(Type.Missing);

                        System.Runtime.InteropServices.Marshal.ReleaseComObject(sheet);
                    }

                    newSheet = (Worksheet)sheets.Add(sheets[1], Type.Missing, Type.Missing, Type.Missing);
                    newSheet.Name = "My New Sheet";
                    newSheet.Cells[1, 1] = "BOO!";

                    workbook.Save();
                    workbook.Close(null, null, null);
                    excelApp.Quit();
                }
            }
            finally
            {
                System.Runtime.InteropServices.Marshal.ReleaseComObject(newSheet);
                System.Runtime.InteropServices.Marshal.ReleaseComObject(sheets);
                System.Runtime.InteropServices.Marshal.ReleaseComObject(workbook);
                System.Runtime.InteropServices.Marshal.ReleaseComObject(excelApp);

                newSheet = null;
                sheets = null;
                workbook = null;
                excelApp = null;

                GC.Collect();
            }
        }
    }
}

Thank you for all your help.

Simple way is using location.origin
it will return your domain
ex
http://localhost:8000
https://yourdomain.com

then concat with some string...
Enjoy...

<img src={ location.origin+"/images/robot.svg"} alt="robot"/>

More images ?

var images =[
"img1.jpg",
"img2.png",
"img3.jpg",
]

images.map( (image,index) => (

  <img key={index} 
       src={ location.origin+"/images/"+image} 
       alt="robot"
  />
) )

For my part, and without any plug-in, simply saving the file either from the File menu or with keyboards shortcuts

CTRL + S (Windows, Linux) or CMD + S (Mac OS)

briefly displays the current encoding - between parentheses - in the status bar, at the bottom of the editor's window. This suggestion works in Sublime Text 2 and 3.

Note that the displayed encoding to the right in the status bar of Sublime Text 3, may display the wrong encoding of the file if you have attempted to save the file with an encoding that can't represent all the characters in your file. In this case you would have seen an informational dialog and Sublime telling you it's falling back to UTF-8. This may not be the case, so be careful.

What about SDL?

Perhaps it's a bit too complex for your needs, but it's certainly cross-platform.

A common approach to follow to solve this problem.

1.CHECK your SDK manager by running from your android studio and stand alons sdk folder by executing ./android.sh helps you to find broken packages

2. Try installing System emulator images with google API support than the Intel one. Just like , i solved my problem by running into another system image.

3. Experment on KVM based Virtulaization suggested by Google for Linux

Use the following instead:

boost::function<void (int)> f2( boost::bind( &myclass::fun2, this, _1 ) );

This forwards the first parameter passed to the function object to the function using place-holders - you have to tell Boost.Bind how to handle the parameters. With your expression it would try to interpret it as a member function taking no arguments.
See e.g. here or here for common usage patterns.

Note that VC8s cl.exe regularly crashes on Boost.Bind misuses - if in doubt use a test-case with gcc and you will probably get good hints like the template parameters Bind-internals were instantiated with if you read through the output.

docker inspect <containername> | grep log

the for-loop for files uses the $IFS shell variable. in the given script, filenames with a character in them that also is in the $IFS-variable will be seen as two different files in the for-loop. This script fixes it: multiline-mode modifier as given sed-manual doesn't seem to work by default on my ubuntu box, so i sought for a different implemenation and found this with an iterating label, essentially it will only start substitution on the last line of the file if i've understood it correctly.

for has more simple logic to implement so it's faster than foreach.

Expanding on @JetLaggy:

After trying again and again to modify .bash_profile with the MAMP directory, I changed the file permissions for the MAMP php directory and was able to get 'which php' to show the proper directory. Trouble was that other functions didn't work, such as 'php -v'.

So I updated MAMP. http://documentation.mamp.info/en/mamp/installation/updating-mamp

This did the trick for my particular setup. I had to adjust my PATH to reflect the updated version of PHP, but once I did, everything worked!

In order to check if an object is compatible with a given type variable, instead of writing

u is t

you should write

typeof(t).IsInstanceOfType(u)

To increase the phpMyAdmin Session Timeout, open config.inc.php in the root phpMyAdmin directory and add this setting (anywhere).

$cfg['LoginCookieValidity'] = <your_new_timeout>;

Where is some number larger than 1800.

Note:

Always keep on mind that a short cookie lifetime is all well and good for the development server. So do not do this on your production server.

Reference

I'm using this

function get_next_week_start() {
   var now = new Date();
   var next_week_start = new Date(now.getFullYear(), now.getMonth(), now.getDate()+(8 - now.getDay()));
   return next_week_start;
}

You can get individual bytes with anding and shifting operations:

byte1 =  nint & 0x000000ff
byte2 = (nint & 0x0000ff00) >> 8
byte3 = (nint & 0x00ff0000) >> 16
byte4 = (nint & 0xff000000) >> 24

UPDATED 2020 TRY THIS WAY

python manage.py runserver yourIp:8000

ALLOWED_HOSTS = ["*"]

In addition to border-radius: 0, add -webkit-appearance: none;.

When you want an unordered collection of unique elements, use a set. (For example, when you want the set of all the words used in a document).

When you want to collect an immutable ordered list of elements, use a tuple. (For example, when you want a (name, phone_number) pair that you wish to use as an element in a set, you would need a tuple rather than a list since sets require elements be immutable).

When you want to collect a mutable ordered list of elements, use a list. (For example, when you want to append new phone numbers to a list: [number1, number2, ...]).

When you want a mapping from keys to values, use a dict. (For example, when you want a telephone book which maps names to phone numbers: {'John Smith' : '555-1212'}). Note the keys in a dict are unordered. (If you iterate through a dict (telephone book), the keys (names) may show up in any order).

In my case this fixed the issue

1. Go to Project Properties by clicking F4 on the project name
2. Set SSLEnabled = true

Project Properties Image

I sometime use this method:

// It is not importnat what timezone your system is set to.
// Get the UTC offset in seconds:
$offset = date("Z");

// Then subtract if from your original timestamp:
$utc_time = date("Y-m-d H:i:s", strtotime($original_time." -".$offset." Seconds"));

Works all MOST of the time.

The dir you specified is a working directory of running process - it doesn't help to find executable. Use cmd /c winrar ... to run process looking for executable in PATH or try to use absolute path to winrar.

There are many ways, one is to use a counter:

$i = 0;
foreach ($arr as $k => $v) {
    /* Do stuff */
    if (++$i == 2) break;
}

Other way would be to slice the first 2 elements, this isn't as efficient though:

foreach (array_slice($arr, 0, 2) as $k => $v) {
    /* Do stuff */
}

You could also do something like this (basically the same as the first foreach, but with for):

for ($i = 0, reset($arr); list($k,$v) = each($arr) && $i < 2; $i++) {
}

You can also use:

$(window).bind("load", function() { 
    // Your code here.
});

The error you receive is from another method than the one you show here. It's a method that takes a parameter with the name "source". In your Visual Studio Options dialog, disable "Just my code", disable "Step over properties and operators" and enable "Enable .NET Framework source stepping". Make sure the .NET symbols can be found. Then the debugger will break inside the .NET method if it isn't your own. then check the stacktrace to find which value is passed that's null, but shouldn't.

What you should look for is a value that becomes null and prevent that. From looking at your code, it may be the itemsal.Add line that breaks.

Edit

Since you seem to have trouble with debugging in general and LINQ especially, let's try to help you out step by step (also note the expanded first section above if you still want to try it the classic way, I wasn't complete the first time around):

• Narrow down the possible error scenarios by splitting your code;
• Replace locations that can end up null with something deliberately not null;
• If all fails, rewrite your LINQ statement as loop and go through it step by step.

Step 1

First make the code a bit more readable by splitting it in manageable pieces:

// in your using-section, add this:
using Roundsman.BAL;

// keep this in your normal location
var nCounts = from sale in sal
              select new
              {
                  SaleID = sale.OrderID,
                  LineItem = GetLineItem(sale.LineItems)
              };

foreach (var item in nCounts)
{
    foreach (var itmss in item.LineItem)
    {
        itemsal.Add(CreateWeeklyStockList(itmss));
    }
}


// add this as method somewhere
WeeklyStockList CreateWeeklyStockList(LineItem lineItem)
{
    string name = itmss.Item.Name.ToString();  // isn't Name already a string?
    string code = itmss.Item.Code.ToString();  // isn't Code already a string?
    string description = itmss.Item.Description.ToString();  // isn't Description already a string?
    int quantity = Convert.ToInt32(itmss.Item.Quantity); // wouldn't (int) or "as int" be enough?

    return new WeeklyStockList(
                 name, 
                 code, 
                 description,
                 quantity, 
                 2, 2, 2, 2, 2, 2, 2, 2, 2
              );
}

// also add this as a method
LineItem GetLineItem(IEnumerable<LineItem> lineItems)
{
    // add a null-check
    if(lineItems == null)
        throw new ArgumentNullException("lineItems", "Argument cannot be null!");

    // your original code
    from sli in lineItems
    group sli by sli.Item into ItemGroup
    select new
    {
        Item = ItemGroup.Key,
        Weeks = ItemGroup.Select(s => s.Week)
    }
}

The code above is from the top of my head, of course, because I cannot know what type of classes you have and thus cannot test the code before posting. Nevertheless, if you edit it until it is correct (if it isn't so out of the box), then you already stand a large chance the actual error becomes a lot clearer. If not, you should at the very least see a different stacktrace this time (which we still eagerly await!).

Step 2

The next step is to meticulously replace each part that can result in a null reference exception. By that I mean that you replace this:

select new
{
    SaleID = sale.OrderID,
    LineItem = GetLineItem(sale.LineItems)
};

with something like this:

select new
{
    SaleID = 123,
    LineItem = GetLineItem(new LineItem(/*ctor params for empty lineitem here*/))
};

This will create rubbish output, but will narrow the problem down even further to your potential offending line. Do the same as above for other places in the LINQ statements that can end up null (just about everything).

Step 3

This step you'll have to do yourself. But if LINQ fails and gives you such headaches and such unreadable or hard-to-debug code, consider what would happen with the next problem you encounter? And what if it fails on a live environment and you have to solve it under time pressure=

The moral: it's always good to learn new techniques, but sometimes it's even better to grab back to something that's clear and understandable. Nothing against LINQ, I love it, but in this particular case, let it rest, fix it with a simple loop and revisit it in half a year or so.

Conclusion

Actually, nothing to conclude. I went a bit further then I'd normally go with the long-extended answer. I just hope it helps you tackling the problem better and gives you some tools understand how you can narrow down hard-to-debug situations, even without advanced debugging techniques (which we haven't discussed).

Sounds like more work than its worth.

1) Why not just have a single JavaScript variable that stores a reference to the currently selected element\jQuery object.

2) Why not add a class to the currently selected element. Then you could query the DOM for the ".active" class or something.

If your website is using authentication, but you don't have the correct authentication method set up in IIS (e.g. Basic, Forms etc..) then the browser will be getting stuck in a redirect loop. This causes the redirect url to get longer and longer until it explodes.

I had this problem too. It turned out I forgot to include one of the components in app.module.ts

Whenever I see addClass and removeClass I think why not just use toggleClass. In this case we can remove the .clickable class to avoid event bubbling, and to avoid the event from being fired on everything we click inside of the .clickable div.

$(document).on("click", ".close_button", function () { 
    $(this).closest(".grown").toggleClass("spot grown clickable");
});  

$(document).on("click", ".clickable", function () {
    $(this).toggleClass("spot grown clickable");
}); 

I also recommend a parent wrapper for your .clickable divs instead of using the document. I am not sure how you are adding them dynamically so didn't want to assume your layout for you.

Happy Coding :)

Here is a basic example of a global variable that the rest of your functions can access. Here is a live example for you: http://jsfiddle.net/fxCE9/

var myVariable = 'Hello';
alert('value: ' + myVariable);
myFunction1();
alert('value: ' + myVariable);
myFunction2();
alert('value: ' + myVariable);


function myFunction1() {
    myVariable = 'Hello 1';
}

function myFunction2() {
    myVariable = 'Hello 2';
}

If you are doing this within a jQuery ready() function then make sure your variable is inside the ready() function along with your other functions.

    SELECT SUM(Output.count),Output.attr 
FROM
(
    SELECT COUNT(column1  ) AS count,column1 AS attr FROM tab1 GROUP BY column1 
    UNION ALL
    SELECT COUNT(column2) AS count,column2 AS attr FROM tab1 GROUP BY column2
    UNION ALL
    SELECT COUNT(column3) AS count,column3 AS attr FROM tab1 GROUP BY column3) AS Output

    GROUP BY attr 

It's a lot more efficient to use the substr() method instead of split() & pop()

Have a look at the performance differences here: http://jsperf.com/remove-first-character-from-string

// returns: 'html'
var path = require('path');
path.extname('index.html').substr(1);

Update August 2019 As pointed out by @xentek in the comments; substr() is now considered a legacy function (MDN documentation). You can use substring() instead. The difference between substr() and substring() is that the second argument of substr() is the maximum length to return while the second argument of substring() is the index to stop at (without including that character). Also, substr() accepts negative start positions to be used as an offset from the end of the string while substring() does not.

To create a simple time delay, you can import Darwin and then use sleep(seconds) to do the delay. That only takes whole seconds, though, so for more precise measurements you can import Darwin and use usleep(millionths of a second) for very precise measurement. To test this, I wrote:

import Darwin
print("This is one.")
sleep(1)
print("This is two.")
usleep(400000)
print("This is three.")

Which prints, then waits for 1 sec and prints, then waits for 0.4 sec then prints. All worked as expected.

If you are using the batch conversion, in the window click "options" in the "Batch conversion settings-output format" and tick the two boxes "save transparent color" (one under "PNG" and the other under "ICO").

Right click on a file → Ignore → Ignore everything beneath.

If the Ignore option is grayed out then:

1. Stage a file first
2. Right click → Stop Tracking
3. That file will appear in the pane below with a question mark → Right click on it→ Ignore

Here is another solution, that has all the source available in a single, simple ZIP file.

It presents the OpenFileDialog with additional windows flags that makes it work like the Windows 7+ Folder Selection dialog.

Per the website, it is public domain: "There’s no license as such as you are free to take and do with the code what you will."

Checkout __FILE__ and __LINE__ macros

This is what worked for me. Issue is earlier I didn't set Content Type(header) when I used exchange method.

MultiValueMap<String, String> map = new LinkedMultiValueMap<String, String>();
map.add("param1", "123");
map.add("param2", "456");
map.add("param3", "789");
map.add("param4", "123");
map.add("param5", "456");

HttpHeaders headers = new HttpHeaders();
headers.setContentType(MediaType.APPLICATION_FORM_URLENCODED);

final HttpEntity<MultiValueMap<String, String>> entity = new HttpEntity<MultiValueMap<String, String>>(map ,
        headers);
JSONObject jsonObject = null;

try {
    RestTemplate restTemplate = new RestTemplate();
    ResponseEntity<String> responseEntity = restTemplate.exchange(
            "https://url", HttpMethod.POST, entity,
            String.class);

    if (responseEntity.getStatusCode() == HttpStatus.CREATED) {
        try {
            jsonObject = new JSONObject(responseEntity.getBody());
        } catch (JSONException e) {
            throw new RuntimeException("JSONException occurred");
        }
    }
  } catch (final HttpClientErrorException httpClientErrorException) {
        throw new ExternalCallBadRequestException();
  } catch (HttpServerErrorException httpServerErrorException) {
        throw new ExternalCallServerErrorException(httpServerErrorException);
  } catch (Exception exception) {
        throw new ExternalCallServerErrorException(exception);
    } 

ExternalCallBadRequestException and ExternalCallServerErrorException are the custom exceptions here.

Note: Remember HttpClientErrorException is thrown when a 4xx error is received. So if the request you send is wrong either setting header or sending wrong data, you could receive this exception.

What is Angular CLI Budgets? Budgets is one of the less known features of the Angular CLI. It’s a rather small but a very neat feature!

As applications grow in functionality, they also grow in size. Budgets is a feature in the Angular CLI which allows you to set budget thresholds in your configuration to ensure parts of your application stay within boundaries which you set — Official Documentation

Or in other words, we can describe our Angular application as a set of compiled JavaScript files called bundles which are produced by the build process. Angular budgets allows us to configure expected sizes of these bundles. More so, we can configure thresholds for conditions when we want to receive a warning or even fail build with an error if the bundle size gets too out of control!

How To Define A Budget? Angular budgets are defined in the angular.json file. Budgets are defined per project which makes sense because every app in a workspace has different needs.

Thinking pragmatically, it only makes sense to define budgets for the production builds. Prod build creates bundles with “true size” after applying all optimizations like tree-shaking and code minimization.

Oops, a build error! The maximum bundle size was exceeded. This is a great signal that tells us that something went wrong…

1. We might have experimented in our feature and didn’t clean up properly
2. Our tooling can go wrong and perform a bad auto-import, or we pick bad item from the suggested list of imports
3. We might import stuff from lazy modules in inappropriate locations
4. Our new feature is just really big and doesn’t fit into existing budgets

First Approach: Are your files gzipped?

Generally speaking, gzipped file has only about 20% the size of the original file, which can drastically decrease the initial load time of your app. To check if you have gzipped your files, just open the network tab of developer console. In the “Response Headers”, if you should see “Content-Encoding: gzip”, you are good to go.

How to gzip? If you host your Angular app in most of the cloud platforms or CDN, you should not worry about this issue as they probably have handled this for you. However, if you have your own server (such as NodeJS + expressJS) serving your Angular app, definitely check if the files are gzipped. The following is an example to gzip your static assets in a NodeJS + expressJS app. You can hardly imagine this dead simple middleware “compression” would reduce your bundle size from 2.21MB to 495.13KB.

const compression = require('compression')
const express = require('express')
const app = express()
app.use(compression())

Second Approach:: Analyze your Angular bundle

If your bundle size does get too big you may want to analyze your bundle because you may have used an inappropriate large-sized third party package or you forgot to remove some package if you are not using it anymore. Webpack has an amazing feature to give us a visual idea of the composition of a webpack bundle.

It’s super easy to get this graph.

1. npm install -g webpack-bundle-analyzer
2. In your Angular app, run ng build --stats-json (don’t use flag --prod). By enabling --stats-json you will get an additional file stats.json
3. Finally, run webpack-bundle-analyzer ./dist/stats.json and your browser will pop up the page at localhost:8888. Have fun with it.

Also you can use this

private static final String ALLOWED_URI_CHARS = "@#&=*+-_.,:!?()/~'%";
String urlEncoded = Uri.encode(path, ALLOWED_URI_CHARS);

it's the most simple method

It is possible to record screen video directly from your phone or tablet if your device is rooted. I'm working on the SCR Screen Recorder app. To the best of my knowledge this is the only app supporting Tegra devices (including Nexus 7) and Android 4.2. At the moment the app records between 9-18fps depending on device but I'm working to improve that. SCR Screen Recorder is still in beta testing phase so feel free to test it and give feedback.

Change the ands to ors.

Go to "Control Panel" -> "Administrative Tools" and open "Datasources (ODBC)". By default, the tab "User-DSN" will be opened, click "Add" and a dialogue will pop up:

There's a lot of misunderstanding being displayed here. Unicode isn't an encoding, but the Unicode standard is devoted primarily to encoding anyway.

ISO 10646 is the international character set you (probably) care about. It defines a mapping between a set of named characters (e.g., "Latin Capital Letter A" or "Greek small letter alpha") and a set of code points (a number assigned to each -- for example, 61 hexadecimal and 3B1 hexadecimal for those two respectively; for Unicode code points, the standard notation would be U+0061 and U+03B1).

At one time, Unicode defined its own character set, more or less as a competitor to ISO 10646. That was a 16-bit character set, but it was not UTF-16; it was known as UCS-2. It included a rather controversial technique to try to keep the number of necessary characters to a minimum (Han Unification -- basically treating Chinese, Japanese and Korean characters that were quite a bit alike as being the same character).

Since then, the Unicode consortium has tacitly admitted that that wasn't going to work, and now concentrate primarily on ways to encode the ISO 10646 character set. The primary methods are UTF-8, UTF-16 and UCS-4 (aka UTF-32). Those (except for UTF-8) also have LE (little endian) and BE (big-endian) variants.

By itself, "Unicode" could refer to almost any of the above (though we can probably eliminate the others that it shows explicitly, such as UTF-8). Unqualified use of "Unicode" probably happens the most often on Windows, where it will almost certainly refer to UTF-16. Early versions of Windows NT adopted Unicode when UCS-2 was current. After UCS-2 was declared obsolete (around Win2k, if memory serves), they switched to UTF-16, which is the most similar to UCS-2 (in fact, it's identical for characters in the "basic multilingual plane", which covers a lot, including all the characters for most Western European languages).

Tuple is used to refer to a row in a relational database model. But tuple has little bit difference with row.

Here's an example for continuous/regression data (until this issue on GitHub is resolved).

min = np.amin(y)
max = np.amax(y)

# 5 bins may be too few for larger datasets.
bins     = np.linspace(start=min, stop=max, num=5)
y_binned = np.digitize(y, bins, right=True)

X_train, X_test, y_train, y_test = train_test_split(
    X, 
    y, 
    stratify=y_binned
)

• Where start is min and stop is max of your continuous target.
• If you don't set right=True then it will more or less make your max value a separate bin and your split will always fail because too few samples will be in that extra bin.

One (++i) is preincrement, one (i++) is postincrement. The difference is in what value is immediately returned from the expression.

// Psuedocode
int i = 0;
print i++; // Prints 0
print i; // Prints 1
int j = 0;
print ++j; // Prints 1
print j; // Prints 1

Edit: Woops, entirely ignored the loop side of things. There's no actual difference in for loops when it's the 'step' portion (for(...; ...; )), but it can come into play in other cases.

Add nil to the end of the declaration.

// Must be nil or swift complains
var someProtocol:SomeProtocol? = nil

// Init the view
override init(frame: CGRect)
    super.init(frame: frame)
    ...

This worked for my case, but may not work for yours

It's probably caused by a local network connectivity issue (but also a DNS error is possible). Unfortunately HResult is generic, however you can determine the exact issue catching HttpRequestException and then inspecting InnerException: if it's a WebException then you can check the WebException.Status property, for example WebExceptionStatus.NameResolutionFailure should indicate a DNS resolution problem.

It may happen, there isn't much you can do.

What I'd suggest to always wrap that (network related) code in a loop with a try/catch block (as also suggested here for other fallible operations). Handle known exceptions, wait a little (say 1000 msec) and try again (for say 3 times). Only if failed all times then you can quit/report an error to your users. Very raw example like this:

private const int NumberOfRetries = 3;
private const int DelayOnRetry = 1000;

public static async Task<HttpResponseMessage> GetFromUrlAsync(string url) {
    using (var client = new HttpClient()) {
        for (int i=1; i <= NumberOfRetries; ++i) {
            try {
                return await client.GetAsync(url); 
            }
            catch (Exception e) when (i < NumberOfRetries) {
                await Task.Delay(DelayOnRetry);
            }
        }
    }
}

I've setup xampp for my localhost as well, I've not done anything with the files created by xampp during or after setup.

But in the '.htaccess' file, make sure you've set it to something like this. Works for me, and this should not make any difference for you.

RewriteEngine On
RewriteRule ^filename/?$ filename.html

Change .html to whatever format you're using.

Make sure your install is clean, and just make the .htaccess file. Also remember to put one .htaccess file for each directory (don't really know if you can use ONE file for all folders, but to be safe, just do this and it will always work.

The way to do was looking at the code in code/core/Mage/Catalog/Model/Resource/Category/Flat/Collection.php at line 380 in Magento 1.7.2 on the function setPage($pageNum, $pageSize)

 $collection = Mage::getModel('model')
     ->getCollection()
     ->setCurPage(2) // 2nd page
     ->setPageSize(10); // 10 elements per pages

I hope this will help someone.

If you haven't actually registered any users with your existing format then you would be best to switch to using the BCrypt password encoder instead.

It's a lot less hassle, as you don't have to worry about salt at all - the details are completely encapsulated within the encoder. Using BCrypt is stronger than using a plain hash algorithm and it's also a standard which is compatible with applications using other languages.

There's really no reason to choose any of the other options for a new application.

Looks like you forgot adding correct headers to your get request (ask the REST API developer or you specific API description):

HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.header("Accept", "application/xml")
connection.setRequestMethod("GET");
connection.connect();

or

connection.header("Accept", "application/xml;version=1")

The documentation says it best and includes an example, (highlighting mine).

android:weightSum

Defines the maximum weight sum. If unspecified, the sum is computed by adding the layout_weight of all of the children. This can be used for instance to give a single child 50% of the total available space by giving it a layout_weight of 0.5 and setting the weightSum to 1.0.

So to correct superM's example, suppose you have a LinearLayout with horizontal orientation that contains two ImageViews and a TextView with. You define the TextView to have a fixed size, and you'd like the two ImageViews to take up the remaining space equally.

To accomplish this, you would apply layout_weight 1 to each ImageView, none on the TextView, and a weightSum of 2.0 on the LinearLayout.

Only works in IE:

window.open ("mapage.html","","fullscreen=yes");  
window.open('','_parent','');  
window.close();

This was my final... It gets around all the type issues also:

Here is a simple textbox that requires a number:

   public Sub textbox_memorytotal_TextChanged(sender As Object, e As EventArgs) Handles textbox_memorytotal.TextChanged
        TextboxOnlyNumbers(sender)
    End Sub

and here is the procedure that corrects all bad input:

Public Sub TextboxOnlyNumbers(ByRef objTxtBox As TextBox)

    ' ONLY allow numbers
    If Not IsNumeric(objTxtBox.Text) Then

        ' Don't process things like too many backspaces
        If objTxtBox.Text.Length > 0 Then

            MsgBox("Numerical Values only!")

            Try
                ' If something bad was entered delete the last character
                objTxtBox.Text = objTxtBox.Text.Substring(0, objTxtBox.Text.Length - 1)

                ' Put the cursor and the END of the corrected number
                objTxtBox.Select(objTxtBox.Text.Length + 1, 1)

            Catch ex As Exception
            End Try
        End If
    End If
End Sub

Go back to specific page:

  import { useHistory } from "react-router-dom";

  const history = useHistory();
  
  const routeChange = () => {
    let path = '/login';
    history.push(path);
  };

Go back to previous page:

  import { useHistory } from "react-router-dom";

  const history = useHistory();
  
  const routeChange = () => {
    history.goBack()
  };

A slightly more general solution based on join, that works even for pandas.Timestamp:

print("\n".join(map(str, my_list)))

see RFC6265:

The user agent will reject cookies unless the Domain attribute specifies a scope for the cookie that would include the origin server. For example, the user agent will accept a cookie with a Domain attribute of "example.com" or of "foo.example.com" from foo.example.com, but the user agent will not accept a cookie with a Domain attribute of "bar.example.com" or of "baz.foo.example.com".

NOTE: For security reasons, many user agents are configured to reject Domain attributes that correspond to "public suffixes". For example, some user agents will reject Domain attributes of "com" or "co.uk". (See Section 5.3 for more information.)

But the above mentioned workaround with image/iframe works, though it's not recommended due to its insecurity.

I got the solution:

The problem with solutions based on sums of numbers is they don't take into account the cost of storing and working with numbers with large exponents... in practice, for it to work for very large n, a big numbers library would be used. We can analyse the space utilisation for these algorithms.

We can analyse the time and space complexity of sdcvvc and Dimitris Andreou's algorithms.

Storage:

l_j = ceil (log_2 (sum_{i=1}^n i^j))
l_j > log_2 n^j  (assuming n >= 0, k >= 0)
l_j > j log_2 n \in \Omega(j log n)

l_j < log_2 ((sum_{i=1}^n i)^j) + 1
l_j < j log_2 (n) + j log_2 (n + 1) - j log_2 (2) + 1
l_j < j log_2 n + j + c \in O(j log n)`

So l_j \in \Theta(j log n)

Total storage used: \sum_{j=1}^k l_j \in \Theta(k^2 log n)

Space used: assuming that computing a^j takes ceil(log_2 j) time, total time:

t = k ceil(\sum_i=1^n log_2 (i)) = k ceil(log_2 (\prod_i=1^n (i)))
t > k log_2 (n^n + O(n^(n-1)))
t > k log_2 (n^n) = kn log_2 (n)  \in \Omega(kn log n)
t < k log_2 (\prod_i=1^n i^i) + 1
t < kn log_2 (n) + 1 \in O(kn log n)

Total time used: \Theta(kn log n)

If this time and space is satisfactory, you can use a simple recursive algorithm. Let b!i be the ith entry in the bag, n the number of numbers before removals, and k the number of removals. In Haskell syntax...

let
  -- O(1)
  isInRange low high v = (v >= low) && (v <= high)
  -- O(n - k)
  countInRange low high = sum $ map (fromEnum . isInRange low high . (!)b) [1..(n-k)]
  findMissing l low high krange
    -- O(1) if there is nothing to find.
    | krange=0 = l
    -- O(1) if there is only one possibility.
    | low=high = low:l
    -- Otherwise total of O(knlog(n)) time
    | otherwise =
       let
         mid = (low + high) `div` 2
         klow = countInRange low mid
         khigh = krange - klow
       in
         findMissing (findMissing low mid klow) (mid + 1) high khigh
in
  findMising 1 (n - k) k

Storage used: O(k) for list, O(log(n)) for stack: O(k + log(n)) This algorithm is more intuitive, has the same time complexity, and uses less space.

Try activating the virtual env. In my case, using the git command line tool:

source scripts/activate

Solves my problem.

React Native comes with "Dimensions" api which we need to import from 'react-native'

@RSC

for me the critical addition in Xcode Version 6.2 (6C86e) is in override func viewDidLoad()

 self.input.delegate = self;

Tried getting it to work with the return key for hours till I found your post, RSC. Thank you!

Also, if you want to hide the keyboard if you touch anywhere else on the screen:

override func touchesBegan(touches: NSSet, withEvent event: UIEvent) {
        self.view.endEditing(true);
    }

IE doesn't allow pressing the ENTER key for form submission if the submit button is not visible, and the form has more than one field. Give it what it wants by providing a 1x1 pixel transparent image as a submit button. Of course it will take up a pixel of the layout, but look what you have to do to hide it.

<input type="image" src="img/1x1trans.gif"/>

The arguments that you provide to a bashscript will appear in the variables $1 and $2 and $3 where the number refers to the argument. $0 is the command itself.

The arguments are seperated by spaces, so if you would provide the -from and -to in the command, they will end up in these variables too, so for this:

./ocrscript.sh -from /home/kristoffer/test.png -to /home/kristoffer/test.txt

You'll get:

$0    # ocrscript.sh
$1    # -from
$2    # /home/kristoffer/test.png
$3    # -to
$4    # /home/kristoffer/test.txt

It might be easier to omit the -from and the -to, like:

ocrscript.sh /home/kristoffer/test.png /home/kristoffer/test.txt

Then you'll have:

$1    # /home/kristoffer/test.png
$2    # /home/kristoffer/test.txt

The downside is that you'll have to supply it in the right order. There are libraries that can make it easier to parse named arguments on the command line, but usually for simple shell scripts you should just use the easy way, if it's no problem.

Then you can do:

/usr/local/bin/abbyyocr9 -rl Swedish -if "$1" -of "$2" 2>&1

The double quotes around the $1 and the $2 are not always necessary but are adviced, because some strings won't work if you don't put them between double quotes.

The simplest way in laravel 5 is:

$listings=Listing::take(10)->get();

return view('view.name',compact('listings'));

About efficiency and concernig time spent on allocation, I made this simple test below, I created many instances through these two ways (one at a time):

for (int k = 0 ; k < 30000000; ++k)
{
    // took more time than using new
    std::shared_ptr<int> foo = std::make_shared<int> (10);

    // was faster than using make_shared
    std::shared_ptr<int> foo2 = std::shared_ptr<int>(new int(10));
}

The thing is, using make_shared took the double time compared with using new. So, using new there are two heap allocations instead of one using make_shared. Maybe this is a stupid test but doesn't it show that using make_shared takes more time than using new? Of course, I'm talking about time used only.

My mistake was that I was keeping the Javascript file ( tag) above the html declaration.

It worked by placing the js script tag at the bottom of the body inside the body. (I did not the script on load of the page.)

1. Asks you when to stop [seconds]
2. Adds '0' at starting [1-9]

import time
import sys

stop = int(input('> '))
second = 0
print('> Stopwatch Started.')

while stop > second:
    if second < 9:
        second = second + 1
        time.sleep(1)
        sys.stdout.write('\r> ' + '0' + str(second))
    else:
        second += 1
        time.sleep(1)
        sys.stdout.write('\r' + '> ' + str(second))

print('\n> Stopwatch Stopped.')

You could use git-sizer. In the --verbose setting, the example output is (below). Look for the Total size of files line.

SELECT username,

The provided answers have issues with relative Url's, such as "/some/path/" This is a limitation of the Uri and UriBuilder class, which is rather hard to understand, since I don't see any reason why relative urls would be problematic when it comes to query manipulation.

Here is a workaround that works for both absolute and relative paths, written and tested in .NET 4:

(small note: this should also work in .NET 4.5, you will only have to change propInfo.GetValue(values, null) to propInfo.GetValue(values))

  public static class UriExtensions{
    /// <summary>
    ///     Adds query string value to an existing url, both absolute and relative URI's are supported.
    /// </summary>
    /// <example>
    /// <code>
    ///     // returns "www.domain.com/test?param1=val1&amp;param2=val2&amp;param3=val3"
    ///     new Uri("www.domain.com/test?param1=val1").ExtendQuery(new Dictionary&lt;string, string&gt; { { "param2", "val2" }, { "param3", "val3" } }); 
    /// 
    ///     // returns "/test?param1=val1&amp;param2=val2&amp;param3=val3"
    ///     new Uri("/test?param1=val1").ExtendQuery(new Dictionary&lt;string, string&gt; { { "param2", "val2" }, { "param3", "val3" } }); 
    /// </code>
    /// </example>
    /// <param name="uri"></param>
    /// <param name="values"></param>
    /// <returns></returns>
    public static Uri ExtendQuery(this Uri uri, IDictionary<string, string> values) {
      var baseUrl = uri.ToString();
      var queryString = string.Empty;
      if (baseUrl.Contains("?")) {
        var urlSplit = baseUrl.Split('?');
        baseUrl = urlSplit[0];
        queryString = urlSplit.Length > 1 ? urlSplit[1] : string.Empty;
      }

      NameValueCollection queryCollection = HttpUtility.ParseQueryString(queryString);
      foreach (var kvp in values ?? new Dictionary<string, string>()) {
        queryCollection[kvp.Key] = kvp.Value;
      }
      var uriKind = uri.IsAbsoluteUri ? UriKind.Absolute : UriKind.Relative;
      return queryCollection.Count == 0 
        ? new Uri(baseUrl, uriKind) 
        : new Uri(string.Format("{0}?{1}", baseUrl, queryCollection), uriKind);
    }

    /// <summary>
    ///     Adds query string value to an existing url, both absolute and relative URI's are supported.

    /// </code>
    /// </example>
    /// <param name="uri"></param>
    /// <param name="values"></param>
    /// <returns></returns>
    public static Uri ExtendQuery(this Uri uri, object values) {
      return ExtendQuery(uri, values.GetType().GetProperties().ToDictionary
      (
          propInfo => propInfo.Name,
          propInfo => { var value = propInfo.GetValue(values, null); return value != null ? value.ToString() : null; }

    }
  }

For those who got this error in AngularJS and not jQuery:

I got it in AngularJS v1.5.8 by trying to ng-include a type="text/ng-template" that didn't exist.

 <div ng-include="tab.content">...</div>

Make sure that when you use ng-include, the data for that directive points to an actual page/section. Otherwise, you probably wanted:

<div>{{tab.content}}</div>

For anyone looking to use this and keep the 'click' functionality (as John Landheer mentions in his comment), you can do it with just a couple of modifications:

Add a couple of globals:

var clickms = 100;
var lastTouchDown = -1;

Then modify the switch statement from the original to this:

var d = new Date();
switch(event.type)
{
    case "touchstart": type = "mousedown"; lastTouchDown = d.getTime(); break;
    case "touchmove": type="mousemove"; lastTouchDown = -1; break;        
    case "touchend": if(lastTouchDown > -1 && (d.getTime() - lastTouchDown) < clickms){lastTouchDown = -1; type="click"; break;} type="mouseup"; break;
    default: return;
}

You may want to adjust 'clickms' to your tastes. Basically it's just watching for a 'touchstart' followed quickly by a 'touchend' to simulate a click.

If you want to ONLY count the documents with sent_at defined with a value of null (don't count the documents with sent_at not set):

db.emails.count({sent_at: { $type: 10 }})

This is a decoder that is specifically written to avoid the need for a buffer, by writing directly to a putchar function. This is based on wikibook's implementation https://en.wikibooks.org/wiki/Algorithm_Implementation/Miscellaneous/Base64#C

This is not as easy to use as other options above. However, it can be of use in embedded systems, where you want to dump a large file without allocating another large buffer to store the resultant base64 datauri string. (It's a pity that datauri does not let you specify the filename).

You can make use of $parsers as shown below,this solved it for me.

window.module.directive('myDate', function(dateFilter) {
  return {
    restrict: 'EAC',
    require: '?ngModel',
    link: function(scope, element, attrs, ngModel) {
      ngModel.$parsers.push(function(viewValue) {
        return dateFilter(viewValue,'yyyy-MM-dd');
      });
    }
  };
});

HTML:

<p class="input-group datepicker" >
  <input
     type="text"
     class="form-control"
     name="name"
     datepicker-popup="yyyy-MM-dd"
     date-type="string"
     show-weeks="false"
     ng-model="data[$parent.editable.name]" 
     is-open="$parent.opened"
     min-date="minDate"
     close-text="Close"
     ng-required="{{editable.mandatory}}"
     show-button-bar="false"
     close-on-date-selection="false"
     my-date />
  <span class="input-group-btn">
    <button type="button" class="btn btn-default" ng-click="openDatePicker($event)">
      <i class="glyphicon glyphicon-calendar"></i>
    </button>
  </span>
</p>

You could check if the scroll-offsets are in the bounds. If they go beyond, set them back.

var scrollX = 0;
var scrollY = 0;
var scrollMinX = 0;
var scrollMinY = 0;
var scrollMaxX = document.body.scrollWidth - window.innerWidth;
var scrollMaxY = document.body.scrollHeight - window.innerHeight;

// make sure that we work with the correct dimensions
window.addEventListener('resize', function () {
  scrollMaxX = document.body.scrollWidth - window.innerWidth;
  scrollMaxY = document.body.scrollHeight - window.innerHeight;
}, false);

// where the magic happens
window.addEventListener('scroll', function () {
  scrollX = window.scrollX;
  scrollY = window.scrollY;

  if (scrollX <= scrollMinX) scrollTo(scrollMinX, window.scrollY);
  if (scrollX >= scrollMaxX) scrollTo(scrollMaxX, window.scrollY);

  if (scrollY <= scrollMinY) scrollTo(window.scrollX, scrollMinY);
  if (scrollY >= scrollMaxY) scrollTo(window.scrollX, scrollMaxY);
}, false);

By using this query you can see all open transactions.

List All:

if you want to kill a hang transaction copy transaction id and kill transaction by using this command:

KILL <id>    // e.g KILL 16543

Changing the first letter to uppercase on the file's name and class name works.

file: controllers/Login.php

class: class Login extends CI_Controller { ... }

The file name, as the class name, should starts with capital letter. This rule applys to models too.

https://www.codeigniter.com/user_guide/general/models.html

To simplify,

for include

1. When the base use case is executed, the included use case is executed EVERYTIME.
2. The base use case required the completion of the included use case in order to be completed.

a typical example: between login and verify password

(login) --- << include >> ---> (verify password)

for the login process to success, "verify password" must be successful as well.

for extend

1. When the base use case is executed, the extended use case is executed only SOMETIMES
2. The extended use case will happen only when certain criteria are met.

a typical example: between login and show error message (only happened sometimes)

(login) <--- << extend >> --- (show error message)

"show error message" only happens sometimes when the login process failed.

From my experience and Maven best practices there are two kinds of "parent poms"

• "company" parent pom - this pom contains your company specific information and configuration that inherit every pom and doesn't need to be copied. These informations are:

  • repositories
  • distribution managment sections
  • common plugins configurations (like maven-compiler-plugin source and target versions)
  • organization, developers, etc

  Preparing this parent pom need to be done with caution, because all your company poms will inherit from it, so this pom have to be mature and stable (releasing a version of parent pom should not affect to release all your company projects!)

• second kind of parent pom is a multimodule parent. I prefer your first solution - this is a default maven convention for multi module projects, very often represents VCS code structure

The intention is to be scalable to a large scale build so should be scalable to a large number of projects and artifacts.

Mutliprojects have structure of trees - so you aren't arrown down to one level of parent pom. Try to find a suitable project struture for your needs - a classic exmample is how to disrtibute mutimodule projects

distibution/
documentation/
myproject/
  myproject-core/
  myproject-api/
  myproject-app/
  pom.xml
pom.xml

A few bonus questions:

• Where is the best place to define the various shared configuration as in source control, deployment directories, common plugins etc. (I'm assuming the parent but I've often been bitten by this and they've ended up in each project rather than a common one).

This configuration has to be wisely splitted into a "company" parent pom and project parent pom(s). Things related to all you project go to "company" parent and this related to current project go to project one's.

• How do the maven-release plugin, hudson and nexus deal with how you set up your multi-projects (possibly a giant question, it's more if anyone has been caught out when by how a multi-project build has been set up)?

Company parent pom have to be released first. For multiprojects standard rules applies. CI server need to know all to build the project correctly.

You need to declare the content within <span class="class_name"></span>. After it the line will be break.

\A means line feed character.

.class_name::after {
  content: "\A";
  white-space: pre;
}

The DNS server seems out of order. You can use another DNS server such as 8.8.8.8. Put nameserver 8.8.8.8 to the first line of /etc/resolv.conf.

I prefer to use two options, white spaces and empty:

test = test.Where(x => !string.IsNullOrEmpty(x)).ToArray();
test = test.Where(x => !string.IsNullOrWhiteSpace(x)).ToArray();

A refinement to JustinStolle's edit (Eran Yogev's use of BlockCopy).

The proposed solution is indeed faster than using Encoding. Problem is that it doesn't work for encoding byte arrays of uneven length. As given, it raises an out-of-bound exception. Increasing the length by 1 leaves a trailing byte when decoding from string.

For me, the need came when I wanted to encode from DataTable to JSON. I was looking for a way to encode binary fields into strings and decode from string back to byte[].

I therefore created two classes - one that wraps the above solution (when encoding from strings it's fine, because the lengths are always even), and another that handles byte[] encoding.

I solved the uneven length problem by adding a single character that tells me if the original length of the binary array was odd ('1') or even ('0')

As follows:

public static class StringEncoder
{
    static byte[] EncodeToBytes(string str)
    {
        byte[] bytes = new byte[str.Length * sizeof(char)];
        System.Buffer.BlockCopy(str.ToCharArray(), 0, bytes, 0, bytes.Length);
        return bytes;
    }
    static string DecodeToString(byte[] bytes)
    {
        char[] chars = new char[bytes.Length / sizeof(char)];
        System.Buffer.BlockCopy(bytes, 0, chars, 0, bytes.Length);
        return new string(chars);
    }
}

public static class BytesEncoder
{
    public static string EncodeToString(byte[] bytes)
    {
        bool even = (bytes.Length % 2 == 0);
        char[] chars = new char[1 + bytes.Length / sizeof(char) + (even ? 0 : 1)];
        chars[0] = (even ? '0' : '1');
        System.Buffer.BlockCopy(bytes, 0, chars, 2, bytes.Length);

        return new string(chars);
    }
    public static byte[] DecodeToBytes(string str)
    {
        bool even = str[0] == '0';
        byte[] bytes = new byte[(str.Length - 1) * sizeof(char) + (even ? 0 : -1)];
        char[] chars = str.ToCharArray();
        System.Buffer.BlockCopy(chars, 2, bytes, 0, bytes.Length);

        return bytes;
    }
}

The ParameterizedThreadStart takes one parameter. You can use that to send one parameter, or a custom class containing several properties.

Another method is to put the method that you want to start as an instance member in a class along with properties for the parameters that you want to set. Create an instance of the class, set the properties and start the thread specifying the instance and the method, and the method can access the properties.

I haven't seen a short, easy to understand answer here--so I'll give it a try.

With a shallow copy, any object pointed to by the source is also pointed to by the destination (so that no referenced objects are copied).

With a deep copy, any object pointed to by the source is copied and the copy is pointed to by the destination (so there will now be 2 of each referenced object). This recurses down the object tree.

Two line PowerShell answer:

# Store in variable
$Global:csv = (mysql -uroot -p -hlocalhost -Ddatabase_name -B -e "SELECT * FROM some_table") `
| ConvertFrom-Csv -Delimiter "`t"

# Out to csv
$Global:csv | Export-Csv "C:\temp\file.csv" -NoTypeInformation

Boom-bata-boom

-D = the name of your database

-e = query

-B = tab-delimited

A small note on try/finally: The finally will always execute unless

• System.exit() is called.
• The JVM crashes.
• The try{} block never ends (e.g. endless loop).

This command is working fine for me ubuntu 16.04 LTS:

Merging json objects is fairly straight forward but has a few edge cases when dealing with key collisions. The biggest issues have to do with one object having a value of a simple type and the other having a complex type (Array or Object). You have to decide how you want to implement that. Our choice when we implemented this for json passed to chef-solo was to merge Objects and use the first source Object's value in all other cases.

This was our solution:

from collections import Mapping
import json


original = json.loads(jsonStringA)
addition = json.loads(jsonStringB)

for key, value in addition.iteritems():
    if key in original:
        original_value = original[key]
        if isinstance(value, Mapping) and isinstance(original_value, Mapping):
            merge_dicts(original_value, value)
        elif not (isinstance(value, Mapping) or 
                  isinstance(original_value, Mapping)):
            original[key] = value
        else:
            raise ValueError('Attempting to merge {} with value {}'.format(
                key, original_value))
    else:
        original[key] = value

You could add another case after the first case to check for lists if you want to merge those as well, or for specific cases when special keys are encountered.

You could go for an inner box shadow:

div[contenteditable=true] {
  box-shadow: inset 0px 1px 4px #666;
}

I updated the jsfiddle from Jarish: http://jsfiddle.net/ZevvE/2/

List<String> items = new ArrayList<>();
items.add("A");
items.add("B");
items.add("C");
items.add("D");
items.add("E");

//lambda
//Output : A,B,C,D,E
items.forEach(item->System.out.println(item));

//Output : C
items.forEach(item->{
    System.out.println(item);
    System.out.println(item.toLowerCase());
  }
});

The code works well for me.

$str = substr($str ,-(strlen($str)-1));

Maybe, contribute with answers too.

In theory, there's nothing preventing you from sending a request body in a GET request. The HTTP protocol allows it, but have no defined semantics, so it's up to you to document what exactly is going to happen when a client sends a GET payload. For instance, you have to define if parameters in a JSON body are equivalent to querystring parameters or something else entirely.

However, since there are no clearly defined semantics, you have no guarantee that implementations between your application and the client will respect it. A server or proxy might reject the whole request, or ignore the body, or anything else. The REST way to deal with broken implementations is to circumvent it in a way that's decoupled from your application, so I'd say you have two options that can be considered best practices.

The simple option is to use POST instead of GET as recommended by other answers. Since POST is not standardized by HTTP, you'll have to document how exactly that's supposed to work.

Another option, which I prefer, is to implement your application assuming the GET payload is never tampered with. Then, in case something has a broken implementation, you allow clients to override the HTTP method with the X-HTTP-Method-Override, which is a popular convention for clients to emulate HTTP methods with POST. So, if a client has a broken implementation, it can write the GET request as a POST, sending the X-HTTP-Method-Override: GET method, and you can have a middleware that's decoupled from your application implementation and rewrites the method accordingly. This is the best option if you're a purist.

To view entries in Drupal's own internal log system (the watchdog database table), go to http://example.com/admin/reports/dblog. These can include Drupal-specific errors as well as general PHP or MySQL errors that have been thrown.

Use the watchdog() function to add an entry to this log from your own custom module.

When Drupal bootstraps it uses the PHP function set_error_handler() to set its own error handler for PHP errors. Therefore, whenever a PHP error occurs within Drupal it will be logged through the watchdog() call at admin/reports/dblog. If you look for PHP fatal errors, for example, in /var/log/apache/error.log and don't see them, this is why. Other errors, e.g. Apache errors, should still be logged in /var/log, or wherever you have it configured to log to.

You have to declare the array variable as an array:

Dim test(10) As Variant

Install nmap,

sudo apt-get install nmap

then

nmap -sP 192.168.1.*

or more commonly

nmap -sn 192.168.1.0/24

will scan the entire .1 to .254 range

This does a simple ping scan in the entire subnet to see which hosts are online.

I had a version mismatch in my nuget dependencies between projects in a solution. Using the consolidate feature in Visual Studio helped identify and fix this.

function _cron_exe($schedules) {
        if ($obj->get_option('cronenabledisable') == "yes") {
            // $interval = 1*20;
            $interval = $obj->get_option('cronhowtime');
            if ($obj->get_option('crontiming') == 'minutes') {
                $interval = $interval * 60;
            } else if ($obj->get_option('crontiming') == 'hours') {
                $interval = $interval * 3600;
            } else if ($obj->get_option('crontiming') == 'days') {
                $interval = $interval * 86400;
            }
            $schedules['hourlys'] = array(
                'interval' => $interval,
                'display' => 'cronjob'
            );
            return $schedules;
        }

}

If you look at the inheritance tree (in version 2.6), HTMLParser inherits from SGMLParser which inherits from ParserBase which doesn't inherits from object. I.e. HTMLParser is an old-style class.

About your checking with isinstance, I did a quick test in ipython:

In [1]: class A:
   ...:     pass
   ...: 

In [2]: isinstance(A, object)
Out[2]: True

Even if a class is old-style class, it's still an instance of object.

I think this is very easy to do with very few lines. here is my solution

.buttonToLink{
   background: none;
   border: none;
   color: red
}

.buttonToLink:hover{
   background: none;
   text-decoration: underline;
}

<button  class="buttonToLink">A simple link button</button>

You can try something like this. Here on click of image button I toggle the imageview.

holder.imgitem.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View view) {
            if(!onclick){
            mSparseBooleanArray.put((Integer) view.getTag(), true);
            holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_delete_overlay_com);
            onclick=true;}
            else if(onclick)
            {
                 mSparseBooleanArray.put((Integer) view.getTag(), false);
                  holder.imgoverlay.setImageResource(R.drawable.ipad_768x1024_editmode_selection_com);

            onclick=false;
            }
        }
    });

Here is a regex for the following most common phone number scenarios. Although this is tailored from a US perspective for area codes it works for international scenarios.

1. The actual number should be 10 digits only.
2. For US numbers area code may be surrounded with parentheses ().
3. The country code can be 1 to 3 digits long. Optionally may be preceded by a + sign.
4. There may be dashes, spaces, dots or no spaces between country code, area code and the rest of the number.

5. A valid phone number cannot be all zeros.

   ^(?!\b(0)\1+\b)(\+?\d{1,3}[. -]?)?\(?\d{3}\)?([. -]?)\d{3}\3\d{4}$
   

Explanation:

    ^ - start of expression  
    (?!\b(0)\1+\b) - (?!)Negative Look ahead. \b - word boundary around a '0' character. \1 backtrack to previous capturing group (zero). Basically don't match all zeros.  
    (\+?\d{1,3}[. -]?)? - '\+?' plus sign before country code is optional.\d{1,3} - country code can be 1 to 3 digits long. '[. -]?' - spaces,dots and dashes are optional. The last question mark is to make country code optional.  
    \(?\d{3}\)? - '\)?' is to make parentheses optional. \d{3} - match 3 digit area code.  
    ([. -]?) - optional space, dash or dot

Vanilla Javascript Answer

var c = document.getElementById("myElement").getBoundingClientRect();
var bot = c.bottom;
var rgt = c.right;

To be clear the element can be anything so long as you have allocated an id to it <img> <div> <p> etc.

for example

<img
    id='myElement'
    src='/img/logout.png'
    className='logoutImg img-button'
    alt='Logout'
/>

it can be helpful

public static int vCodeApk(String path) {
    PackageManager pm = G.context.getPackageManager();
    PackageInfo info = pm.getPackageArchiveInfo(path, 0);
    return info.versionCode;
    //        Toast.makeText(this, "VersionCode : " + info.versionCode + ", VersionName : " + info.versionName, Toast.LENGTH_LONG).show();
}

G is my Application class :

public class G extends Application {

I had some trouble with $scope.$watch but after a lot of testing I found out that my data-ng-model="User.UserName" was badly named and after I changed it to data-ng-model="UserName" everything worked fine. I expect it to be the . in the name causing the issue.

I installed miniconda and found all the installed packages in /miniconda3/pkgs

If you have data already present in both the tables and you want to update a table column values based on some condition then use this

UPDATE Table1 set Name=(select t2.Name from Table2 t2 where t2.id=Table1.id)

Enabled="false" in aspx page

I tried with gcc and come up with for my need I was forced to use the last alternative, to compile with out error.

typedef enum state {a = 0, b = 1, c = 2} state;

typedef enum state {a = 0, b = 1, c = 2} state;

typedef enum state old; // New type, alias of the state type.
typedef enum state new; // New type, alias of the state type.

new now     = a;
old before  = b;

printf("State   now = %d \n", now);
printf("Sate before = %d \n\n", before);

You have to insert the call into the AWT message queue so all the timing happens correctly, otherwise it will not dispatch the correct event sequence, especially in a multi-threaded program. When this is done you may handle the resulting event sequence exactly as you would if the user has clicked on the [x] button for an OS suppled decorated JFrame.

public void closeWindow()
{
    if(awtWindow_ != null) {
        EventQueue.invokeLater(new Runnable() {
            public void run() {
                awtWindow_.dispatchEvent(new WindowEvent(awtWindow_, WindowEvent.WINDOW_CLOSING));
            }
        });
    }
}

You really don't need jQuery for this.

var myarr = ["I", "like", "turtles"];
var arraycontainsturtles = (myarr.indexOf("turtles") > -1);

Hint: indexOf returns a number, representing the position where the specified searchvalue occurs for the first time, or -1 if it never occurs

or

function arrayContains(needle, arrhaystack)
{
    return (arrhaystack.indexOf(needle) > -1);
}

It's worth noting that array.indexOf(..) is not supported in IE < 9, but jQuery's indexOf(...) function will work even for those older versions.

Just had this problem, what worked for me was to use localhost.fiddler:

 <endpoint address="http://localhost.fiddler/test/test.svc"
            binding="basicHttpBinding" 
            bindingConfiguration="customBinding" 
            contract="test" 
            name="customBinding"/>

private void checkBox1_CheckedChanged(object sender, EventArgs e)
{
    if (checkBoxImage.Checked)
    {
        groupBoxImage.Show();
    }
    else if (!checkBoxImage.Checked)
    {
        groupBoxImage.Hide(); 
    }
}

When you use the dir([object]) built-in function, you can get the __sizeof__ of the built-in function.

>>> a = -1
>>> a.__sizeof__()

I am an old hand at programming and came back recently to my old passion and am struggling to fit in this Object oriented, event driven bright new world and while i see the advantages of the non sequential behavior of Javascript there are time where it really get in the way of simplicity and reusability. A simple example I have worked on was to take a photo (Mobile phone programmed in javascript, HTML, phonegap, ...), resize it and upload it on a web site. The ideal sequence is :

1. Take a photo
2. Load the photo in an img element
3. Resize the picture (Using Pixastic)
4. Upload it to a web site
5. Inform the user on success failure

All this would be a very simple sequential program if we would have each step returning control to the next one when it is finished, but in reality :

1. Take a photo is async, so the program attempt to load it in the img element before it exist
2. Load the photo is async so the resize picture start before the img is fully loaded
3. Resize is async so Upload to the web site start before the Picture is completely resized
4. Upload to the web site is asyn so the program continue before the photo is completely uploaded.

And btw 4 of the 5 steps involve callback functions.

My solution thus is to nest each step in the previous one and use .onload and other similar stratagems, It look something like this :

takeAPhoto(takeaphotocallback(photo) {
  photo.onload = function () {
    resizePhoto(photo, resizePhotoCallback(photo) {
      uploadPhoto(photo, uploadPhotoCallback(status) {
        informUserOnOutcome();
      });
    }); 
  };
  loadPhoto(photo);
});

(I hope I did not make too many mistakes bringing the code to it's essential the real thing is just too distracting)

This is I believe a perfect example where async is no good and sync is good, because contrary to Ui event handling we must have each step finish before the next is executed, but the code is a Russian doll construction, it is confusing and unreadable, the code reusability is difficult to achieve because of all the nesting it is simply difficult to bring to the inner function all the parameters needed without passing them to each container in turn or using evil global variables, and I would have loved that the result of all this code would give me a return code, but the first container will be finished well before the return code will be available.

Now to go back to Tom initial question, what would be the smart, easy to read, easy to reuse solution to what would have been a very simple program 15 years ago using let say C and a dumb electronic board ?

The requirement is in fact so simple that I have the impression that I must be missing a fundamental understanding of Javsascript and modern programming, Surely technology is meant to fuel productivity right ?.

Thanks for your patience

cmake's ExternalProject_Add indeed can used, but what I did not like about it - is that it performs something during build, continuous poll, etc... I would prefer to build project during build phase, nothing else. I have tried to override ExternalProject_Add in several attempts, unfortunately without success.

Then I have tried also to add git submodule, but that drags whole git repository, while in certain cases I need only subset of whole git repository. What I have checked - it's indeed possible to perform sparse git checkout, but that require separate function, which I wrote below.

#-----------------------------------------------------------------------------
#
# Performs sparse (partial) git checkout
#
#   into ${checkoutDir} from ${url} of ${branch}
#
# List of folders and files to pull can be specified after that.
#-----------------------------------------------------------------------------
function (SparseGitCheckout checkoutDir url branch)
    if(EXISTS ${checkoutDir})
        return()
    endif()

    message("-------------------------------------------------------------------")
    message("sparse git checkout to ${checkoutDir}...")
    message("-------------------------------------------------------------------")

    file(MAKE_DIRECTORY ${checkoutDir})

    set(cmds "git init")
    set(cmds ${cmds} "git remote add -f origin --no-tags -t master ${url}")
    set(cmds ${cmds} "git config core.sparseCheckout true")

    # This command is executed via file WRITE
    # echo <file or folder> >> .git/info/sparse-checkout")

    set(cmds ${cmds} "git pull --depth=1 origin ${branch}")

    # message("In directory: ${checkoutDir}")

    foreach( cmd ${cmds})
        message("- ${cmd}")
        string(REPLACE " " ";" cmdList ${cmd})

        #message("Outfile: ${outFile}")
        #message("Final command: ${cmdList}")

        if(pull IN_LIST cmdList)
            string (REPLACE ";" "\n" FILES "${ARGN}")
            file(WRITE ${checkoutDir}/.git/info/sparse-checkout ${FILES} )
        endif()

        execute_process(
            COMMAND ${cmdList}
            WORKING_DIRECTORY ${checkoutDir}
            RESULT_VARIABLE ret
        )

        if(NOT ret EQUAL "0")
            message("error: previous command failed, see explanation above")
            file(REMOVE_RECURSE ${checkoutDir})
            break()
        endif()
    endforeach()

endfunction()


SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_197 https://github.com/catchorg/Catch2.git v1.9.7 single_include)
SparseGitCheckout(${CMAKE_BINARY_DIR}/catch_master https://github.com/catchorg/Catch2.git master single_include)

I have added two function calls below just to illustrate how to use the function.

Someone might not like to checkout master / trunk, as that one might be broken - then it's always possible to specify specific tag.

Checkout will be performed only once, until you clear the cache folder.

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

app.filter('htmlToPlaintext', function()
{
    return function(text)
    {
        return  text ? String(text).replace(/<[^>]+>/gm, '') : '';
    };
});

<p>{{DetailblogList.description | htmlToPlaintext}}</p>

I just tried the following:

 $ cat gdbtest.c
 int abc = 43;

 int main()
 {
   abc = 10;
 }
 $ gcc -g -o gdbtest gdbtest.c
 $ gdb gdbtest
 ...
 (gdb) watch abc
 Hardware watchpoint 1: abc
 (gdb) r
 Starting program: /home/mweerden/gdbtest 
 ...

 Old value = 43
 New value = 10
 main () at gdbtest.c:6
 6       }
 (gdb) quit

So it seems possible, but you do appear to need some hardware support.

Have a look at View.setVisibility(View.GONE / View.VISIBLE / View.INVISIBLE).

From the API docs:

public void setVisibility(int visibility)

    Since: API Level 1

    Set the enabled state of this view.
    Related XML Attributes: android:visibility

Parameters:
visibility     One of VISIBLE, INVISIBLE, or GONE.

Note that LinearLayout is a ViewGroup which in turn is a View. That is, you may very well call, for instance, myLinearLayout.setVisibility(View.VISIBLE).

This makes sense. If you have any experience with AWT/Swing, you'll recognize it from the relation between Container and Component. (A Container is a Component.)

My solution is to use these 2 mappings:

map <leader>n <Esc><Esc>0qq
map <leader>m q:'<,'>-1normal!@q<CR><Down>

How to use them:

1. Select your lines. If I want to select the next 12 lines I just press V12j
2. Press <leader>n
3. Make your changes to the line
4. Make sure you're in normal mode and then press <leader>m

To make another edit you don't need to make the selection again. Just press <leader>n, make your edit and press <leader>m to apply.

How this works:

• <Esc><Esc>0qq Exit the visual selection, go to the beginning of the line and start recording a macro.

• q Stop recording the macro.

• :'<,'>-1normal!@q<CR> From the start of the visual selection to the line before the end, play the macro on each line.

• <Down> Go back down to the last line.

You can also just map the same key but for different modes:

vmap <leader>m <Esc><Esc>0qq
nmap <leader>m q:'<,'>-1normal!@q<CR><Down>

Although this messes up your ability to make another edit. You'll have to re-select your lines.

Button btn;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_user);

    btn= findViewById(R.id.btn); 

   btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            notification();
        }
    });
  }   



private void notification() {
    NotificationCompat.Builder builder= new 
    NotificationCompat.Builder(this);
    builder.setAutoCancel(true);
    builder.setContentTitle("Work Progress");
    builder.setContentText("Submit your today's work progress");
    builder.setSmallIcon(R.drawable.ic_email_black_24dp);
    Intent intent=new Intent(this, WorkStatus.class);
    PendingIntent pendingIntent= PendingIntent.getActivity(this, 1, intent, 
    PendingIntent.FLAG_UPDATE_CURRENT);
    builder.setContentIntent(pendingIntent);
    builder.setDefaults(Notification.DEFAULT_VIBRATE);
    builder.setDefaults(Notification.DEFAULT_SOUND);

    NotificationManager notificationManager= (NotificationManager) 
    getSystemService(NOTIFICATION_SERVICE);
    notificationManager.notify(1, builder.build());
}

It is complete notification with sound and vibrates

This was what I was searching online but unfortunately found not online but while experimenting on python interpreter.

>>> case  = "caseCamel"
>>> label = "Case Camel"
>>> list  = ["apple", "banana"]
>>>
>>> (case or label) in list
False
>>> list = ["apple", "caseCamel"]
>>> (case or label) in list
True
>>> (case and label) in list
False
>>> list = ["case", "caseCamel", "Case Camel"]
>>> (case and label) in list
True
>>>

and if you have a looong list of variables held in a sublist variable

>>>
>>> list  = ["case", "caseCamel", "Case Camel"]
>>> label = "Case Camel"
>>> case  = "caseCamel"
>>>
>>> sublist = ["unique banana", "very unique banana"]
>>>
>>> # example for if any (at least one) item contained in superset (or statement)
...
>>> next((True for item in sublist if next((True for x in list if x == item), False)), False)
False
>>>
>>> sublist[0] = label
>>>
>>> next((True for item in sublist if next((True for x in list if x == item), False)), False)
True
>>>
>>> # example for whether a subset (all items) contained in superset (and statement)
...
>>> # a bit of demorgan's law
...
>>> next((False for item in sublist if item not in list), True)
False
>>>
>>> sublist[1] = case
>>>
>>> next((False for item in sublist if item not in list), True)
True
>>>
>>> next((True for item in sublist if next((True for x in list if x == item), False)), False)
True
>>>
>>>

One more cause for this:

If the routes are overridden with the same URI (Unknowingly), it causes this error:

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('dashboard/', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']);

In this case route 'my.dashboard' is invalidate as the both routes has same URI ('dashboard', 'dashboard/')

Solution: You should change the URI for either one

Eg:

Route::get('dashboard', ['uses' => 'SomeController@index', 'as' => 'my.dashboard']);
Route::get('home-dashboard', ['uses' => 'SomeController@dashboard', 'as' => 'my.home_dashboard']); 

// See the URI changed for this 'home-dashboard'

Hope it helps some once.

Newer Edit: Lots of things have changed since this question was initially posted - there's a lot of really good information in wallacer's revised answer as well as VisioN's excellent breakdown

Edit: Just because this is the accepted answer; wallacer's answer is indeed much better:

return filename.split('.').pop();

My old answer:

return /[^.]+$/.exec(filename);

Should do it.

Edit: In response to PhiLho's comment, use something like:

return (/[.]/.exec(filename)) ? /[^.]+$/.exec(filename) : undefined;
