You can get the different values with:

set(Article.objects.values_list('comment_id', flat=True))

@Neil's answer is one (perfectly valid!) way of doing it, but you can also simply call matplotlib.use('Agg') before importing matplotlib.pyplot, and then continue as normal.

E.g.

import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
fig.savefig('temp.png')

You don't have to use the Agg backend, as well. The pdf, ps, svg, agg, cairo, and gdk backends can all be used without an X-server. However, only the Agg backend will be built by default (I think?), so there's a good chance that the other backends may not be enabled on your particular install.

Alternately, you can just set the backend parameter in your .matplotlibrc file to automatically have matplotlib.pyplot use the given renderer.

The :nth-child() and :nth-of-type() pseudo-classes allows you to select elements with a formula.

The syntax is :nth-child(an+b), where you replace a and b by numbers of your choice.

For instance, :nth-child(3n+1) selects the 1st, 4th, 7th etc. child.

td:nth-child(3n+1) {  
  /* your stuff here */
}

:nth-of-type() works the same, except that it only considers element of the given type ( in the example).

Since Date implements Comparable, it has a compareTo method just like String does.

So your custom Comparator could look like this:

public class CustomComparator implements Comparator<MyObject> {
    @Override
    public int compare(MyObject o1, MyObject o2) {
        return o1.getStartDate().compareTo(o2.getStartDate());
    }
}

The compare() method must return an int, so you couldn't directly return a boolean like you were planning to anyway.

Your sorting code would be just about like you wrote:

Collections.sort(Database.arrayList, new CustomComparator());

A slightly shorter way to write all this, if you don't need to reuse your comparator, is to write it as an inline anonymous class:

Collections.sort(Database.arrayList, new Comparator<MyObject>() {
    @Override
    public int compare(MyObject o1, MyObject o2) {
        return o1.getStartDate().compareTo(o2.getStartDate());
    }
});

Since java-8

You can now write the last example in a shorter form by using a lambda expression for the Comparator:

Collections.sort(Database.arrayList, 
                        (o1, o2) -> o1.getStartDate().compareTo(o2.getStartDate()));

And List has a sort(Comparator) method, so you can shorten this even further:

Database.arrayList.sort((o1, o2) -> o1.getStartDate().compareTo(o2.getStartDate()));

This is such a common idiom that there's a built-in method to generate a Comparator for a class with a Comparable key:

Database.arrayList.sort(Comparator.comparing(MyObject::getStartDate));

All of these are equivalent forms.

The accepted answer doesn't work for UILocalNotification. For some reason, %%%% (4 percent signs) or the unicode character '\uFF05' only work for this.

So to recap, when formatting your string you may use %%. However, if your string is part of a UILocalNotification, use %%%% or \uFF05.

You info.plist must looks like this:

The error message tells the exact reason: "abstract methods cannot have a body".

They can only be defined in abstract classes and interfaces (interface methods are implicitly abstract!) and the idea is, that the subclass implements the method.

Example:

 public abstract class AbstractGreeter {
   public abstract String getHelloMessage();

   public void sayHello() {
     System.out.println(getHelloMessage());
   }
 }

 public class FrenchGreeter extends AbstractGreeter{

   // we must implement the abstract method
   @Override
   public String getHelloMessage() {
     return "bonjour";
   }
 }

According to the latest Apple Human Interface Guidelines:

In portrait orientation, tab bar icons appear above tab titles. In landscape orientation, the icons and titles appear side-by-side. Depending on the device and orientation, the system displays either a regular or compact tab bar. Your app should include custom tab bar icons for both sizes.

I suggest you to use the above link to understand the full concept. Because apple update it's document in regular interval

This is a very old, but still very useful thread. I came here recently with the same issue. I suggest protecting the sheet when appropriate and unprotecting it when the filter row (eg Row 1) is selected. My solution doesn't use password protection - I don't need it (its a safeguard, not a security feature). I can't find an event handler that recognizes selection of a filter button - so I gave the instruction to my users to first select the filter cell then click the filter button. Here's what I advocate, (I only change protection if it needs to be changed, that may or may not save time - I don't know, but it "feels" right):

Private Sub Worksheet_SelectionChange(ByVal Target As Range)
  Const FilterRow = 1
  Dim c As Range
  Dim NotFilterRow As Boolean
  Dim oldstate As Boolean
  Dim ws As Worksheet
  Set ws = ActiveSheet
  oldstate = ws.ProtectContents
  NotFilterRow = False
  For Each c In Target.Cells
     NotFilterRow = c.Row <> FilterRow
     If NotFilterRow Then Exit For
  Next c
  If NotFilterRow <> oldstate Then
     If NotFilterRow Then
        ws.Protect
     Else
        ws.Unprotect
     End If
  End If
  Set ws = Nothing
End Sub

The 2^nd option is the one you want.

Probably Timerconcept

new CountDownTimer(40000, 1000) { //40000 milli seconds is total time, 1000 milli seconds is time interval

 public void onTick(long millisUntilFinished) {
  }
  public void onFinish() {
 }
}.start();

or

Method 2 ::

Program the timer

Add a new variable of int named time. Set it to 0. Add the following code to onCreate function in MainActivity.java.

//Declare the timer
Timer t = new Timer();
//Set the schedule function and rate
t.scheduleAtFixedRate(new TimerTask() {

    @Override
    public void run() {
        //Called each time when 1000 milliseconds (1 second) (the period parameter)
    }

},
//Set how long before to start calling the TimerTask (in milliseconds)
0,
//Set the amount of time between each execution (in milliseconds)
1000);

Go into the run method and add the following code.

//We must use this function in order to change the text view text
runOnUiThread(new Runnable() {

    @Override
    public void run() {
        TextView tv = (TextView) findViewById(R.id.main_timer_text);
        tv.setText(String.valueOf(time));
        time += 1;
    }

});

Here is a sample from React doc:JavaScript Expressions as Children

function Item(props) {
  return <li>{props.message}</li>;
}

function TodoList() {
  const todos = ['finish doc', 'submit pr', 'nag dan to review'];
  return (
    <ul>
      {todos.map((message) => <Item key={message} message={message} />)}
    </ul>
  );
}

as your case, I suggest writing like this:

function render() {
  return (
    <tbody>
      {numrows.map((roe, index) => <ObjectRow key={index} />)}
    </tbody>
  );
}

Please notice the Key is very important, because React use Key to differ data in array.

You can use the createRef to change the state of the child component from the parent component. Here are all the steps.

1. Create a method to change the state in the child component.

   2 - Create a reference for the child component in parent component using React.createRef().

   3 - Attach reference with the child component using ref={}.

   4 - Call the child component method using this.yor-reference.current.method.

Parent component

class ParentComponent extends Component {
constructor()
{
this.changeChild=React.createRef()
}
  render() {
    return (
      <div>
        <button onClick={this.changeChild.current.toggleMenu()}>
          Toggle Menu from Parent
        </button>
        <ChildComponent ref={this.changeChild} />
      </div>
    );
  }
}

Child Component

class ChildComponent extends Component {
  constructor(props) {
    super(props);
    this.state = {
      open: false;
    }
  }

  toggleMenu=() => {
    this.setState({
      open: !this.state.open
    });
  }

  render() {
    return (
      <Drawer open={this.state.open}/>
    );
  }
}

You want to put the ISNULL inside of the COUNT function, not outside:

Not GOOD: ISNULL(COUNT(field), 0)

GOOD: COUNT(ISNULL(field, 0))

Upstream (as related to) Tracking

The term upstream also has some unambiguous meaning as comes to the suite of GIT tools, especially relative to tracking

For example :

   $git rev-list --count --left-right "@{upstream}"...HEAD
   >4   12

will print (the last cached value of) the number of commits behind (left) and ahead (right) of your current working branch, relative to the (if any) currently tracking remote branch for this local branch. It will print an error message otherwise:

    >error: No upstream branch found for ''

• As has already been said, you may have any number of remotes for one local repository, for example, if you fork a repository from github, then issue a 'pull request', you most certainly have at least two: origin (your forked repo on github) and upstream (the repo on github you forked from). Those are just interchangeable names, only the 'git@...' url identifies them.

Your .git/configreads :

   [remote "origin"]
       fetch = +refs/heads/*:refs/remotes/origin/*
       url = [email protected]:myusername/reponame.git
   [remote "upstream"]
       fetch = +refs/heads/*:refs/remotes/upstream/*
       url = [email protected]:authorname/reponame.git

• On the other hand, @{upstream}'s meaning for GIT is unique :

it is 'the branch' (if any) on 'said remote', which is tracking the 'current branch' on your 'local repository'.

It's the branch you fetch/pull from whenever you issue a plain git fetch/git pull, without arguments.

Let's say want to set the remote branch origin/master to be the tracking branch for the local master branch you've checked out. Just issue :

   $ git branch --set-upstream  master origin/master
   > Branch master set up to track remote branch master from origin.

This adds 2 parameters in .git/config :

   [branch "master"]
       remote = origin
       merge = refs/heads/master

now try (provided 'upstream' remote has a 'dev' branch)

   $ git branch --set-upstream  master upstream/dev
   > Branch master set up to track remote branch dev from upstream.

.git/config now reads:

   [branch "master"]
       remote = upstream
       merge = refs/heads/dev

git-push(1) Manual Page :

   -u
   --set-upstream

For every branch that is up to date or successfully pushed, add upstream (tracking) reference, used by argument-less git-pull(1) and other commands. For more information, see branch.<name>.merge in git-config(1).

git-config(1) Manual Page :

   branch.<name>.merge

Defines, together with branch.<name>.remote, the upstream branch for the given branch. It tells git fetch/git pull/git rebase which branch to merge and can also affect git push (see push.default). \ (...)

   branch.<name>.remote

When in branch < name >, it tells git fetch and git push which remote to fetch from/push to. It defaults to origin if no remote is configured. origin is also used if you are not on any branch.

Upstream and Push (Gotcha)

take a look at git-config(1) Manual Page

   git config --global push.default upstream
   git config --global push.default tracking  (deprecated)

This is to prevent accidental pushes to branches which you’re not ready to push yet.

did you try this ?

$("#yourdiv").load(url, function(){ 

         your functions goes here !!!

there are several way, one i would prefer is using a table in html. you can add two coloum three rows table and place the radio buttons and lable.

<table border="0">

  <td>radio1</td>

  <td><input type="radio" name="sex" value="2"></td>
  <td>radio2</td>

</tr>
</table>

Make (or rather a Makefile) is a buildsystem - it drives the compiler and other build tools to build your code.

CMake is a generator of buildsystems. It can produce Makefiles, it can produce Ninja build files, it can produce KDEvelop or Xcode projects, it can produce Visual Studio solutions. From the same starting point, the same CMakeLists.txt file. So if you have a platform-independent project, CMake is a way to make it buildsystem-independent as well.

If you have Windows developers used to Visual Studio and Unix developers who swear by GNU Make, CMake is (one of) the way(s) to go.

I would always recommend using CMake (or another buildsystem generator, but CMake is my personal preference) if you intend your project to be multi-platform or widely usable. CMake itself also provides some nice features like dependency detection, library interface management, or integration with CTest, CDash and CPack.

Using a buildsystem generator makes your project more future-proof. Even if you're GNU-Make-only now, what if you later decide to expand to other platforms (be it Windows or something embedded), or just want to use an IDE?

If you use .net 4.0 you can use a sorter way:

String.Join<string>(String.Empty, los);

If you are designing your Javafx application using SceneBuilder then use -fx-text-fill(if not available as option then write it in style input box) as style and give the color you want,it will change the text color of your Textfield.

I came here for the same problem and solved it in this way.

Use docker-compose and multiple Dockerfile in separate directories

Don't rename your Dockerfile to Dockerfile.db or Dockerfile.web, it may not be supported by your IDE and you will lose syntax highlighting.

As Kingsley Uchnor said, you can have multiple Dockerfile, one per directory, which represent something you want to build.

I like to have a docker folder which holds each applications and their configuration. Here's an example project folder hierarchy for a web application that has a database.

docker-compose.yml
docker
+-- web
¦   +-- Dockerfile
+-- db
    +-- Dockerfile

docker-compose.yml example:

version: '3'
services:
  web:
    # will build ./docker/web/Dockerfile
    build: ./docker/web
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  db:
    # will build ./docker/db/Dockerfile
    build: ./docker/db
    ports:
      - "3306:3306"
  redis:
    # will use docker hub's redis prebuilt image from here:
    # https://hub.docker.com/_/redis/
    image: "redis:alpine"

docker-compose command line usage example:

# The following command will create and start all containers in the background
# using docker-compose.yml from current directory
docker-compose up -d

# get help
docker-compose --help

In case you need files from previous folders when building your Dockerfile

You can still use the above solution and place your Dockerfile in a directory such as docker/web/Dockerfile, all you need is to set the build context in your docker-compose.yml like this:

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: ./docker/web/Dockerfile
    ports:
     - "5000:5000"
    volumes:
     - .:/code

This way, you'll be able to have things like this:

config-on-root.ini
docker-compose.yml
docker
+-- web
    +-- Dockerfile
    +-- some-other-config.ini

and a ./docker/web/Dockerfile like this:

FROM alpine:latest

COPY config-on-root.ini /
COPY docker/web/some-other-config.ini /

Here are some quick commands from tldr docker-compose. Make sure you refer to official documentation for more details.

I meet the same problem,but ,at last I solve the problem by followed way

((ViewGroup)dialog.getWindow().getDecorView())
.getChildAt(0).startAnimation(AnimationUtils.loadAnimation(
context,android.R.anim.slide_in_left));

Python 3.6+:

coordinates = [('a',1,2), ('b',3,4), ('c',5,6)]
for x in coordinates: plt.annotate(x[0], (x[1], x[2]))

You could compare String representations so:

array1.toString() == array2.toString()
array1.toString() !== array3.toString()

but that would also make

array4 = ['1',2,3,4,5]

equal to array1 if that matters to you

Dispose pattern:

public abstract class DisposableObject : IDisposable
{
    public bool Disposed { get; private set;}      

    public void Dispose()
    {
        Dispose(true);
        GC.SuppressFinalize(this);
    }

    ~DisposableObject()
    {
        Dispose(false);
    }

    private void Dispose(bool disposing)
    {
        if (!Disposed)
        {
            if (disposing)
            {
                DisposeManagedResources();
            }

            DisposeUnmanagedResources();
            Disposed = true;
        }
    }

    protected virtual void DisposeManagedResources() { }
    protected virtual void DisposeUnmanagedResources() { }
}

Example of inheritance:

public class A : DisposableObject
{
    public Component components_a { get; set; }
    private IntPtr handle_a;

    protected override void DisposeManagedResources()
    {
        try
        {
          Console.WriteLine("A_DisposeManagedResources");
          components_a.Dispose();
          components_a = null;
        }
        finally
        { 
          base.DisposeManagedResources();
        }
    }

    protected override void DisposeUnmanagedResources()
    {
        try
        {
          Console.WriteLine("A_DisposeUnmanagedResources");
          CloseHandle(handle_a);
          handle_a = IntPtr.Zero;
        }
        finally
        { 
          base.DisposeUnmanagedResources();
        }
    }
}

public class B : A
{
    public Component components_b { get; set; }
    private IntPtr handle_b;

    protected override void DisposeManagedResources()
    {
        try
        {
          Console.WriteLine("B_DisposeManagedResources");
          components_b.Dispose();
          components_b = null;
        }
        finally
        { 
          base.DisposeManagedResources();
        }
    }

    protected override void DisposeUnmanagedResources()
    {
        try
        {
          Console.WriteLine("B_DisposeUnmanagedResources");
          CloseHandle(handle_b);
          handle_b = IntPtr.Zero;
        }
        finally
        { 
          base.DisposeUnmanagedResources();
        }
    }
}

It's case by case. We want to minimize the "total cost of ownership" of the software over its lifespan. Stating "using namespace std" has some costs, but not using it also has a cost in legibility.

People correctly point out that when using it, when the standard library introduces new symbols and definitions, your code ceases to compile, and you may be forced to rename variables. And yet this is probably good long-term, since future maintainers will be momentarily confused or distracted if you're using a keyword for some surprising purpose.

You don't want to have a template called vector, say, which isn't the vector known by everyone else. And the number of new definitions thus introduced in the C++ library is small enough it may simply not come up. There is a cost to having to do this kind of change, but the cost is not high and is offset by the clarity gained by not using std symbol names for other purposes.

Given the number of classes, variables, and functions, stating std:: on every one might fluff up your code by 50% and make it harder to get your head around. An algorithm or step in a method that could be taken in on one screenful of code now requires scrolling back and forth to follow. This is a real cost. Arguably it may not be a high cost, but people who deny it even exists are inexperienced, dogmatic, or simply wrong.

I'd offer the following rules:

1. std is different from all other libraries. It is the one library everyone basically needs to know, and in my view is best thought of as part of the language. Generally speaking there is an excellent case for using namespace std even if there isn't for other libraries.

2. Never force the decision onto the author of a compilation unit (a .cpp file) by putting this using in a header. Always defer the decision to the compilation unit author. Even in a project that has decided to use using namespace std everywhere may fine a few modules that are best handled as exceptions to that rule.

3. Even though the namespace feature lets you have many modules with symbols defined the same, it's going to be confusing to do so. Keep the names different to the extent possible. Even if not using the namespace feature, if you have a class named foo and std introduces a class named foo, it's probably better long-run to rename your class anyway.

4. An alternative to using namespaces is to manually namespace symbols by prefixing them. I have two libraries I've used for decades, both starting as C libraries, actually, where every symbol is prefixed with "AK" or "SCWin". Generally speaking, this is like avoiding the "using" construct, but you don't write the twin colons. AK::foo() is instead AKFoo(). It makes code 5-10% denser and less verbose, and the only downside is that you'll be in big trouble if you have to use two such libraries that have the same prefixing. Note the X Window libraries are excellent in this regard, except they forgot to do so with a few #defines: TRUE and FALSE should have been XTRUE and XFALSE, and this set up a namespace clash with Sybase or Oracle that likewise used TRUE and FALSE with different values! (ASCII 0 and 1 in the case of the database!) One special advantage of this is that it applies seemlessly to preprocessor definitions, whereas the C++ using/namespace system doesn't handle them. A nice benefit of this is that it gives an organic slope from being part of a project to eventually being a library. In a large application of mine, all window classes are prefixed Win, all signal-processing modules Mod, and so on. There's little chance of any of these being reused so there's no practical benefit to making each group into a library, but it makes obvious in a few seconds how the project breaks into sub-projects.

Project will effects Columns in the table while Select effects the Rows. on other hand Project is use to select the columns with specefic properties rather than Select the all of columns data

I would go about it somewhat like this:

<html>
    <head>
        <title>Print Test Page</title>
        <script>
            printDivCSS = new String ('<link href="myprintstyle.css" rel="stylesheet" type="text/css">')
            function printDiv(divId) {
                window.frames["print_frame"].document.body.innerHTML=printDivCSS + document.getElementById(divId).innerHTML;
                window.frames["print_frame"].window.focus();
                window.frames["print_frame"].window.print();
            }
        </script>
    </head>

    <body>
        <h1><b><center>This is a test page for printing</center></b><hr color=#00cc00 width=95%></h1>
        <b>Div 1:</b> <a href="javascript:printDiv('div1')">Print</a><br>
        <div id="div1">This is the div1's print output</div>
        <br><br>
        <b>Div 2:</b> <a href="javascript:printDiv('div2')">Print</a><br>
        <div id="div2">This is the div2's print output</div>
        <br><br>
        <b>Div 3:</b> <a href="javascript:printDiv('div3')">Print</a><br>
        <div id="div3">This is the div3's print output</div>
        <iframe name="print_frame" width="0" height="0" frameborder="0" src="about:blank"></iframe>
    </body>
</html>

You can use \blacksquare ¦:

When creating TeX, Knuth provided the symbol ¦ (solid black square), also called by mathematicians tombstone or Halmos symbol (after Paul Halmos, who pioneered its use as an equivalent of Q.E.D.). The tombstone is sometimes open: ? (hollow black square).

Go back in to where you added the jar. I believe its the libraries tab, I don't have Eclipse open but that sounds right. to the left of the jar file you added there should be an arrow pointing right, click that and 3 or 4 options expand, one of them being the source file of the library. Click on that and click edit(I think you can also double click it) then locate the file or folder on your hard disk, you probably have to click apply or okay and you're good to go, same with javadoc and i think the last one is native libraries. I don't pay much attention when I'm in there anymore if you couldn't tell. That's what you were asking, right?

Which version of bootstrap are you using? The early versions of Bootstrap 3 (3.0, 3.0.1) didn't work with this functionality.

col-md-offset-0 should be working as seen in this bootstrap example found here (http://getbootstrap.com/css/#grid-responsive-resets):

<div class="row">
   <div class="col-sm-5 col-md-6">.col-sm-5 .col-md-6</div>
   <div class="col-sm-5 col-sm-offset-2 col-md-6 col-md-offset-0">.col-sm-5 .col-sm-offset-2 .col-md-6 .col-md-offset-0</div>
</div>

1st Option

date_trunc('month', timestamp_column)::date

It will maintain the date format with all months starting at day one.

Example:

2016-08-01
2016-09-01
2016-10-01
2016-11-01
2016-12-01
2017-01-01

2nd Option

to_char(timestamp_column, 'YYYY-MM')

This solution proposed by @yairchu worked fine in my case. I really wanted to discard 'day' info.

Here goes:

DECLARE @var nvarchar(max) = 'Man''s best friend';

You will note that the ' is escaped by doubling it to ''.

Since the string delimiter is ' and not ", there is no need to escape ":

DECLARE @var nvarchar(max) = '"My Name is Luca" is a great song';

The second example in the MSDN page on DECLARE shows the correct syntax.

There is a difference.

When the ^ character appears outside of [] matches the beginning of the line (or string). When the ^ character appears inside the [], it matches any character not appearing inside the [].

To complete a bit more previous great answers, you need to be aware that forms leverage observables to detect and handle value changes. It's something really important and powerful. Both Mark and dfsq described this aspect in their answers.

Observables allow not only to use the subscribe method (something similar to the then method of promises in Angular 1). You can go further if needed to implement some processing chains for updated data in forms.

I mean you can specify at this level the debounce time with the debounceTime method. This allows you to wait for an amount of time before handling the change and correctly handle several inputs:

this.form.valueChanges
    .debounceTime(500)
    .subscribe(data => console.log('form changes', data));

You can also directly plug the processing you want to trigger (some asynchronous one for example) when values are updated. For example, if you want to handle a text value to filter a list based on an AJAX request, you can leverage the switchMap method:

this.textValue.valueChanges
    .debounceTime(500)
    .switchMap(data => this.httpService.getListValues(data))
    .subscribe(data => console.log('new list values', data));

You even go further by linking the returned observable directly to a property of your component:

this.list = this.textValue.valueChanges
    .debounceTime(500)
    .switchMap(data => this.httpService.getListValues(data))
    .subscribe(data => console.log('new list values', data));

and display it using the async pipe:

<ul>
  <li *ngFor="#elt of (list | async)">{{elt.name}}</li>
</ul>

Just to say that you need to think the way to handle forms differently in Angular2 (a much more powerful way ;-)).

Hope it helps you, Thierry

dataframe['column'].squeeze() should solve this. It basically changes the dataframe column to a list.

I tried morewry answer but it does not work for me. I had trouble to have the same clientWidth with safari comparing to others browsers and this code solved the problem:

var get_safe_value = function(elm,callback){
    var sty = elm.style
    sty.transform = "translateZ(1px)";
    var ret = callback(elm)//you can get here the value you want
    sty.transform = "";
    return ret
}
// for safari to have the good clientWidth
var $fBody = document.body //the element you need to fix
var clientW = get_safe_value($fBody,function(elm){return $fBody.clientWidth})

It is really strange because if I try again to get the clientWidth after get_safe_value, I obtain a bad value with safari, the getter has to be between sty.transform = "translateZ(1px)"; and sty.transform = "";

The other solution that works definitively is

var $fBody = document.body //the element you need to fix
$fBody.style.display = 'none';
var temp = $.body.offsetHeight;
$fBody.style.display = ""
temp = $.body.offsetHeight;

var clientW = $fBody.clientWidth

The problem is that you lose focus and scroll states.

For Eclipse, setting -Dspring.profiles.active variable in the VM arguments would do the trick.

Go to

Right Click Project --> Run as --> Run Configurations --> Arguments

And add your -Dspring.profiles.active=dev in the VM arguments

Could it be more useful for you to use the length of the list len(n) to inform your decision rather than checking n[i] for each possible length?

Here is a query for showing all databases in one Sql engine

Select * from Sys.Databases

UPDATE ed
SET ed.kWh = ted.kWh
FROM energydata ed
INNER JOIN temp_energydata ted ON ted.webmeterID = ed.webmeterID

Same problem here. Reverted to build tools 18.1.1, restarted Eclipse and that fixed it.

If you are referring to the npm module sleep, it notes in the readme that sleep will block execution. So you are right - it isn't what you want. Instead you want to use setTimeout which is non-blocking. Here is an example:

setTimeout(function() {
  console.log('hello world!');
}, 5000);

For anyone looking to do this using es7 async/await, this example should help:

const snooze = ms => new Promise(resolve => setTimeout(resolve, ms));

const example = async () => {
  console.log('About to snooze without halting the event loop...');
  await snooze(1000);
  console.log('done!');
};

example();

Here is a simple implementation, to reverse array of any type, plus full/partial support.

import java.util.logging.Logger;

public final class ArrayReverser {
 private static final Logger LOGGER = Logger.getLogger(ArrayReverser.class.getName());

 private ArrayReverser () {

 }

 public static <T> void reverse(T[] seed) {
    reverse(seed, 0, seed.length);
 }

 public static <T> void reverse(T[] seed, int startIndexInclusive, int endIndexExclusive) {
    if (seed == null || seed.length == 0) {
        LOGGER.warning("Nothing to rotate");
    }
    int start = startIndexInclusive < 0 ? 0 : startIndexInclusive;
    int end = Math.min(seed.length, endIndexExclusive) - 1;
    while (start < end) {
        swap(seed, start, end);
        start++;
        end--;
    }
}

 private static <T> void swap(T[] seed, int start, int end) {
    T temp =  seed[start];
    seed[start] = seed[end];
    seed[end] = temp;
 }  

}

Here is the corresponding Unit Test

import static org.hamcrest.CoreMatchers.is;
import static org.junit.Assert.assertThat;

import org.junit.Before;
import org.junit.Test;

public class ArrayReverserTest {
private Integer[] seed;

@Before
public void doBeforeEachTestCase() {
    this.seed = new Integer[]{1,2,3,4,5,6,7,8};
}

@Test
public void wholeArrayReverse() {
    ArrayReverser.<Integer>reverse(seed);
    assertThat(seed[0], is(8));
}

 @Test
 public void partialArrayReverse() {
    ArrayReverser.<Integer>reverse(seed, 1, 5);
    assertThat(seed[1], is(5));
 }
}

You can do this with array_keys and count.

$array = array("blue", "red", "green", "blue", "blue");
echo count(array_keys($array, "blue"));

Output:

3

If you already have the xml, and comes more than one attribute, you can handle it as follows:

String output = "<ciudads><ciudad><idCiudad>1</idCiudad>
<nomCiudad>BOGOTA</nomCiudad></ciudad><ciudad><idCiudad>6</idCiudad>
<nomCiudad>Pereira</nomCiudad></ciudads>";
DocumentBuilder db = DocumentBuilderFactory.newInstance()
    .newDocumentBuilder();
InputSource is = new InputSource();
is.setCharacterStream(new StringReader(output));

Document doc = db.parse(is);
NodeList nodes = ((org.w3c.dom.Document) doc)
    .getElementsByTagName("ciudad");

for (int i = 0; i < nodes.getLength(); i++) {           
    Ciudad ciudad = new Ciudad();
    Element element = (Element) nodes.item(i);

    NodeList name = element.getElementsByTagName("idCiudad");
    Element element2 = (Element) name.item(0);
    ciudad.setIdCiudad(Integer
        .valueOf(getCharacterDataFromElement(element2)));

    NodeList title = element.getElementsByTagName("nomCiudad");
    element2 = (Element) title.item(0);
    ciudad.setNombre(getCharacterDataFromElement(element2));

    ciudades.getPartnerAccount().add(ciudad);
}
}

for (Ciudad ciudad1 : ciudades.getPartnerAccount()) {
System.out.println(ciudad1.getIdCiudad());
System.out.println(ciudad1.getNombre());
}

the method getCharacterDataFromElement is

public static String getCharacterDataFromElement(Element e) {
Node child = e.getFirstChild();
if (child instanceof CharacterData) {
CharacterData cd = (CharacterData) child;

return cd.getData();
}
return "";
}

Sometimes we may not have access to a Jenkins machine to copy a folder directly into another Jenkins instance. So I wrote a menu driven utility which uses Jenkins REST API calls to install plugins and jobs from one Jenkins instance to another.

For plugin migration:

1. GET request: {SOURCE_JENKINS_SERVER}/pluginManager/api/json?depth=1 will get you the list of plugins installed with their version.

2. You can send a POST request with the following parameters to install these plugins.

   final_url=`{DESTINATION_JENKINS_SERVER}/pluginManager/installNecessaryPlugins`
   
   data=`<jenkins><install plugin="{PLUGIN_NAME}@latest"/></jenkins>` (where, latest will fetch the latest version of the plugin_name)
   
   auth=`(destination_jenkins_username, destination_jenkins_password)`
   
   header=`{crumb_field:crumb_value,"Content-Type":"application/xml”}` (where crumb_field=Jenkins-Crumb and get crumb value using API call {DESTINATION_JENKINS_SERVER}/crumbIssuer/api/json
   

For job migration:

1. You can get the list of jobs installed on {SOURCE_JENKINS_URL} using a REST call, {SOURCE_JENKINS_URL}/view/All/api/json
2. Then you can get each job config.xml file from the jobs on {SOURCE_JENKINS_URL} using the job URL {SOURCE_JENKINS_URL}/job/{JOB_NAME}.
3. Use this config.xml file to POST the content of the XML file on {DESTINATION_JENKINS_URL} and that will create a job on {DESTINATION_JENKINS_URL}.

I have created a menu-driven utility in Python which asks the user to start plugin or Jenkins migration and uses Jenkins REST API calls to do it.

You can refer the JenkinsMigration.docx from this URL jenkinsjenkinsmigrationjenkinsrestapi

you need to take 2 (hex) chars at the same time... then calculate the int value and after that make the char conversion like...

char d = (char)intValue;

do this for every 2chars in the hex string

this works if the string chars are only 0-9A-F:

#include <stdio.h>
#include <string.h>

int hex_to_int(char c){
        int first = c / 16 - 3;
        int second = c % 16;
        int result = first*10 + second;
        if(result > 9) result--;
        return result;
}

int hex_to_ascii(char c, char d){
        int high = hex_to_int(c) * 16;
        int low = hex_to_int(d);
        return high+low;
}

int main(){
        const char* st = "48656C6C6F3B";
        int length = strlen(st);
        int i;
        char buf = 0;
        for(i = 0; i < length; i++){
                if(i % 2 != 0){
                        printf("%c", hex_to_ascii(buf, st[i]));
                }else{
                        buf = st[i];
                }
        }
}

Heredoc's are a great alternative to quoted strings because of increased readability and maintainability. You don't have to escape quotes and (good) IDEs or text editors will use the proper syntax highlighting.

A very common example: echoing out HTML from within PHP:

$html = <<<HTML
  <div class='something'>
    <ul class='mylist'>
      <li>$something</li>
      <li>$whatever</li>
      <li>$testing123</li>
    </ul>
  </div>
HTML;

// Sometime later
echo $html;

It is easy to read and easy to maintain.

The alternative is echoing quoted strings, which end up containing escaped quotes and IDEs aren't going to highlight the syntax for that language, which leads to poor readability and more difficulty in maintenance.

Updated answer for Your Common Sense

Of course you wouldn't want to see an SQL query highlighted as HTML. To use other languages, simply change the language in the syntax:

$sql = <<<SQL
       SELECT * FROM table
SQL;

The best, quickest and easiest way to resolve the comma in data issue is to use Excel to save a comma separated file after having set Windows' list separator setting to something other than a comma (such as a pipe). This will then generate a pipe (or whatever) separated file for you that you can then import. This is described here.

Have a look and see if the the JDK is at:

Library/Java/JavaVirtualMachines/ Or /System/Library/Java/JavaVirtualMachines/

Check this earlier SO post: JDK on OSX 10.7 Lion

Assumption:

list - List<String>

Using Java 8 Streams,

• to get first N elements from a list into a list,

  List<String> firstNElementsList = list.stream().limit(n).collect(Collectors.toList());

• to get first N elements from a list into an Array,

  String[] firstNElementsArray = list.stream().limit(n).collect(Collectors.toList()).toArray(new String[n]);

Install tether via npm like below

npm install tether --save-dev

then add tether to your html above bootstrap like below

<script src="node_modules/tether/dist/js/tether.min.js"></script>
<script src="jspm_packages/github/twbs/[email protected]/js/bootstrap.js"></script>

you can do a multi div layout like this

<div class="fieldcontainer">
    <div class="label"></div>
    <div class="field"></div>
</div>

where .fieldcontainer { clear: both; } .label { float: left; width: ___ } .field { float: left; }

Or, I actually prefer tables for forms like this. This is very much tabular data and it comes out very clean. Both will work though.

Reposting the working answer from the other question: How to horizontally center a floating element of a variable width?

Assuming the element which is floated and will be centered is a div with an id="content" ...

<body>
<div id="wrap">
   <div id="content">
   This will be centered
   </div>
</div>
</body>

And apply the following CSS

#wrap {
    float: left;
    position: relative;
    left: 50%;
}

#content {
    float: left;
    position: relative;
    left: -50%;
}

Here is a good reference regarding that http://dev.opera.com/articles/view/35-floats-and-clearing/#centeringfloats

This should also work and is a closer answer to what is asked in the question:

for i in range(len(x)):
    if valeur.item(i) <= 0.6:
        print ("this works")
    else:   
        print ("valeur is too high")

Just wanted to make a time comparison for both solutions (for 30K rows DF):

In [1]: df = DataFrame({'foo':['a','b','c'], 'bar':[1, 2, 3], 'new':['apple', 'banana', 'pear']})

In [2]: big = pd.concat([df] * 10**4, ignore_index=True)

In [3]: big.shape
Out[3]: (30000, 3)

In [4]: %timeit big.apply(lambda x:'%s_%s_%s' % (x['bar'],x['foo'],x['new']),axis=1)
1 loop, best of 3: 881 ms per loop

In [5]: %timeit big['bar'].astype(str)+'_'+big['foo']+'_'+big['new']
10 loops, best of 3: 44.2 ms per loop

a few more options:

In [6]: %timeit big.ix[:, :-1].astype(str).add('_').sum(axis=1).str.cat(big.new)
10 loops, best of 3: 72.2 ms per loop

In [11]: %timeit big.astype(str).add('_').sum(axis=1).str[:-1]
10 loops, best of 3: 82.3 ms per loop

• UTF-8 is variable 1 to 4 bytes.

• UTF-16 is variable 2 or 4 bytes.

• UTF-32 is fixed 4 bytes.

Note: UTF-8 can take 1 to 6 bytes with latest convention: https://lists.gnu.org/archive/html/help-flex/2005-01/msg00030.html

There is a get method in HashMap:

for (String keys : objectSet.keySet())  
{
   System.out.println(keys + ":"+ objectSet.get(keys));
}

You override __hash__ if you want special hash-semantics, and __cmp__ or __eq__ in order to make your class usable as a key. Objects who compare equal need to have the same hash value.

Python expects __hash__ to return an integer, returning Banana() is not recommended :)

User defined classes have __hash__ by default that calls id(self), as you noted.

There is some extra tips from the documentation.:

Classes which inherit a __hash__() method from a parent class but change the meaning of __cmp__() or __eq__() such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting __hash__ = None in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checking isinstance(obj, collections.Hashable) (unlike classes which define their own __hash__() to explicitly raise TypeError).

I must add :

I had the same problem, it was coming from the fact that my teammate had a different version of cordova, and commited plugins on the repo with his version.

For all cordova plugins, I had to :

cordova plugin rm <plugin-name> 
cordova plugin add <plugin-name>

And ask my teammate to update his cordova to match my version

Your code is fine, but the problem is inside the batch file.

You have to show the content of the bat file, your problem is in the paths inside the bat file.

I experienced that problem only when running on real device (iPhone SE). On simulator project worked as expected.

I did try all fixes from this very thread and from here. None of those worked for me.

For me problem was solved after restarting iPhone (sic!).

I did:

• clean build folder,
• clean derived data,
• delete app from device,
• reboot device

And it finally works. :)

If every other solution fails don't forget to try it out.

To configure Docker to work with a proxy you need to add the HTTPS_PROXY / HTTP_PROXY environment variable to the Docker sysconfig file (/etc/sysconfig/docker).

Depending on if you use init.d or the services tool you need to add the "export" statement (due to Debian Bug report logs - #767441. Examples in /etc/default/docker are misleading regarding the supported syntax):

HTTPS_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
HTTP_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
export HTTP_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"
export HTTPS_PROXY="https://<user>:<password>@<proxy-host>:<proxy-port>"

The Docker repository (Docker Hub) only supports HTTPS. To get Docker working with SSL intercepting proxies you have to add the proxy root certificate to the systems trust store.

For CentOS, copy the file to /etc/pki/ca-trust/source/anchors/ and update the CA trust store and restart the Docker service.

If your proxy uses NTLMv2 authentication - you need to use intermediate proxies like Cntlm to bridge the authentication. This blog post explains it in detail.

Just try the following coding...very simple to generate CSV with the values of HTML Tables. No browser issues will come

Makefiles and build files are about automating your build. If you use a script like MSBuild or NAnt, you can build your project or solution directly from command line. This in turn makes it possible to automate the build, have it run by a build server.

Besides building your solution it is typical that a build script includes task to run unit tests, report code coverage and complexity and more.

The difference between these two approaches is as follows:

Synchronous way: It waits for each operation to complete, after that only it executes the next operation. For your query: The console.log() command will not be executed until & unless the query has finished executing to get all the result from Database.

Asynchronous way: It never waits for each operation to complete, rather it executes all operations in the first GO only. The result of each operation will be handled once the result is available. For your query: The console.log() command will be executed soon after the Database.Query() method. While the Database query runs in the background and loads the result once it is finished retrieving the data.

Use cases

1. If your operations are not doing very heavy lifting like querying huge data from DB then go ahead with Synchronous way otherwise Asynchronous way.

2. In Asynchronous way you can show some Progress indicator to the user while in background you can continue with your heavy weight works. This is an ideal scenario for GUI apps.

Same problem with Anaconda running on Ubuntu 15.10. I closed the terminal and opened a new window and it worked fine.

@ivelin: UUID can have capitals. So you'll either need to toLowerCase() the string or use:

[a-fA-F0-9]{8}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{4}-[a-fA-F0-9]{12}

Would have just commented this but not enough rep :)

WITH (NOLOCK) is a hint on a table level. Setting the transaction isolation level to READ_UNCOMMITTED with affect the connection. The difference is in terms of scope. See READUNCOMMITTED and NOLOCK in the SQL Server documentation here:

For TRANSACTION ISOLATION LEVEL: http://technet.microsoft.com/en-us/library/ms173763.aspx

In general, you can the characters of a string from i until j with string[i:j]. string[:2] is shorthand for string[0:2]. This works for arrays as well.

Learn about python's slice notation at the official tutorial

Replace the contents of the first <directory> tag.

Remove:

<Directory /usr/share/phpMyAdmin/>
 <IfModule mod_authz_core.c>
  # Apache 2.4
  <RequireAny>
    Require ip 127.0.0.1
    Require ip ::1
  </RequireAny>
 </IfModule>
 <IfModule !mod_authz_core.c>
  # Apache 2.2
  Order Deny,Allow
  Deny from All
  Allow from 127.0.0.1
  Allow from ::1
 </IfModule>
</Directory>

And place this instead:

<Directory /usr/share/phpMyAdmin/>
 Order allow,deny
 Allow from all
</Directory>

Don't forget to restart Apache afterwards.

Use escape characters for example this code:

var message = "I want to learn \"c#\"";
Console.WriteLine(message);

will output:

I want to learn "c#"

next = pow(2, ceil(log(x)/log(2)));

This works by finding the number you'd have raise 2 by to get x (take the log of the number, and divide by the log of the desired base, see wikipedia for more). Then round that up with ceil to get the nearest whole number power.

This is a more general purpose (i.e. slower!) method than the bitwise methods linked elsewhere, but good to know the maths, eh?

Html.CheckBoxFor expects a Func<TModel, bool> as the first parameter. Therefore your lambda must return a bool, you are currently returning an instance of List<Checkboxes>:

model => model.EmploymentType

You need to iterate over the List<Checkboxes> to output each checkbox:

@for (int i = 0; i < Model.EmploymentType.Count; i++)
{
    @Html.HiddenFor(m => m.EmploymentType[i].Text)
    @Html.CheckBoxFor(m => m.EmploymentType[i].Checked, 
              new { id = string.Format("employmentType_{0}", i) })
}

You should use the StringFormat on the Binding. You can use either standard string formats, or custom string formats:

<TextBox Text="{Binding Value, StringFormat=N2}" />
<TextBox Text="{Binding Value, StringFormat={}{0:#,#.00}}" />

Note that the StringFormat only works when the target property is of type string. If you are trying to set something like a Content property (typeof(object)), you will need to use a custom StringFormatConverter (like here), and pass your format string as the ConverterParameter.

Edit for updated question

So, if your ViewModel defines the precision, I'd recommend doing this as a MultiBinding, and creating your own IMultiValueConverter. This is pretty annoying in practice, to go from a simple binding to one that needs to be expanded out to a MultiBinding, but if the precision isn't known at compile time, this is pretty much all you can do. Your IMultiValueConverter would need to take the value, and the precision, and output the formatted string. You'd be able to do this using String.Format.

However, for things like a ContentControl, you can much more easily do this with a Style:

<Style TargetType="{x:Type ContentControl}">
    <Setter Property="ContentStringFormat" 
            Value="{Binding Resolution, StringFormat=N{0}}" />
</Style>

Any control that exposes a ContentStringFormat can be used like this. Unfortunately, TextBox doesn't have anything like that.

To get Correct Week Count for Date 2018-12-31 Please use below Code

$day_count = date('N',strtotime('2018-12-31'));
$week_count = date('W',strtotime('2018-12-31'));    


if($week_count=='01' && date('m',strtotime('2018-12-31'))==12){
    $yr_count = date('y',strtotime('2018-12-31')) + 1;
}else{
    $yr_count = date('y',strtotime('2018-12-31'));
}

If you are using Bootstrap, please add the following customised style setting for your table:

.table>tbody>tr>td, 
.table>tbody>tr>th, 
.table>tfoot>tr>td, 
.table>tfoot>tr>th, 
.table>thead>tr>td, 
.table>thead>tr>th {
      vertical-align: middle;
 }

You need to subscribe to the observable and pass a callback that processes emitted values

this.myService.getConfig().subscribe(val => console.log(val));

I took Boann's answer and used it to create a more flexible query string builder that supports lists and arrays, just like php's http_build_query method:

public static byte[] httpBuildQueryString(Map<String, Object> postsData) throws UnsupportedEncodingException {
    StringBuilder postData = new StringBuilder();
    for (Map.Entry<String,Object> param : postsData.entrySet()) {
        if (postData.length() != 0) postData.append('&');

        Object value = param.getValue();
        String key = param.getKey();

        if(value instanceof Object[] || value instanceof List<?>)
        {
            int size = value instanceof Object[] ? ((Object[])value).length : ((List<?>)value).size();
            for(int i = 0; i < size; i++)
            {
                Object val = value instanceof Object[] ? ((Object[])value)[i] : ((List<?>)value).get(i);
                if(i>0) postData.append('&');
                postData.append(URLEncoder.encode(key + "[" + i + "]", "UTF-8"));
                postData.append('=');            
                postData.append(URLEncoder.encode(String.valueOf(val), "UTF-8"));
            }
        }
        else
        {
            postData.append(URLEncoder.encode(key, "UTF-8"));
            postData.append('=');            
            postData.append(URLEncoder.encode(String.valueOf(value), "UTF-8"));
        }
    }
    return postData.toString().getBytes("UTF-8");
}

It is probably not the best thing to do. You need to at least check out your PHP error log for things going wrong ;)

parse_cols is deprecated, use usecols instead

that is:

This clearly is a bad case of controller logic in a view. It would be better to do this in a controller and return the desired view.

[ChildActionOnly]
public ActionResult Results() 
{
    EnumerableRowCollection<DataRow> custs = ViewBag.Customers;
    bool anyRows = custs.Any();

    if(anyRows == false)
    {
        return View("NoResults");
    }
    else
    {
        return View("OtherView");
    }
}

Modify NoResults.cshtml to a Partial.

And call this as a Partial view in the parent view

@Html.Partial("Results")

You might have to pass the Customer collection as a model to the Result action or in a ViewDataDictionary due to reasons explained here: Can't access ViewBag in a partial view in ASP.NET MVC3

The ChildActionOnly attribute will make sure you cannot go to this page by navigating and that this view must be rendered as a partial, thus by a parent view. cfr: Using ChildActionOnly in MVC

If you need to frequently use LIKE, you can simplify the problem a bit. A custom method like () can be created in the model that inherits the Eloquent ORM:

public  function scopeLike($query, $field, $value){
        return $query->where($field, 'LIKE', "%$value%");
}

So then you can use this method in such way:

User::like('name', 'Tomas')->get();

You can use jQuery load method to get the contents and insert into an element.

Try this:

$(document).ready(function() {
        $("#lesen").click(function() {
                $(".text").load("helloworld.txt");
    }); 
}); 

You, can also add a call back to execute something once the load process is complete

e.g:

$(document).ready(function() {
    $("#lesen").click(function() {
        $(".text").load("helloworld.txt", function(){
            alert("Done Loading");
        });
   }); 
}); 

See §6.7.9 Initialization:

21 If there are fewer initializers in a brace-enclosed list than there are elements or members of an aggregate, or fewer characters in a string literal used to initialize an array of known size than there are elements in the array, the remainder of the aggregate shall be initialized implicitly the same as objects that have static storage duration.

So, yes both of them work. Note that in C99 a new way of initialization, called designated initialization can be used too:

myStruct _m1 = {.c2 = 0, .c1 = 1};

If you mean you want to see them like this:

WORKPLACEID NAME       ADDRESS        TELEPHONE
----------- ---------- -------------- ---------
          1 HSBC       Nugegoda Road      43434
          2 HNB Bank   Colombo Road      223423

then in SQL Plus you can set the column widths like this (for example):

column name format a10
column address format a20
column telephone format 999999999

You can also specify the line size and page size if necessary like this:

set linesize 100 pagesize 50

You do this by typing those commands into SQL Plus before running the query. Or you can put these commands and the query into a script file e.g. myscript.sql and run that. For example:

column name format a10
column address format a20
column telephone format 999999999

select name, address, telephone
from mytable;

Simple solution is install via this command :

curl -sS https://getcomposer.org/installer | sudo php -- --install-dir=/usr/local/bin --filename=composer

To install package it's very simple :

 composer global require "phpunit/php-invoker=1.1.*"

Ref : composer web site.

CAST(round(cast(getdate()as real),0,1) AS datetime)

This method does not use string function. Date is basically a real datatype with digits before decimal are fraction of a day.

this I guess will be faster than a lot.

See my comment. You need to include the full org.json library when running as android.jar only contains stubs to compile against.

In addition, you must remove the two instances of extra } in your JSON data following longitude.

   private final static String JSON_DATA =
     "{" 
   + "  \"geodata\": [" 
   + "    {" 
   + "      \"id\": \"1\"," 
   + "      \"name\": \"Julie Sherman\","                  
   + "      \"gender\" : \"female\"," 
   + "      \"latitude\" : \"37.33774833333334\"," 
   + "      \"longitude\" : \"-121.88670166666667\""
   + "    }," 
   + "    {" 
   + "      \"id\": \"2\"," 
   + "      \"name\": \"Johnny Depp\","          
   + "      \"gender\" : \"male\"," 
   + "      \"latitude\" : \"37.336453\"," 
   + "      \"longitude\" : \"-121.884985\""
   + "    }" 
   + "  ]" 
   + "}"; 

Apart from that, geodata is in fact not a JSONObject but a JSONArray.

Here is the fully working and tested corrected code:

import org.json.JSONArray;
import org.json.JSONException;
import org.json.JSONObject;

public class ShowActivity {


  private final static String JSON_DATA =
     "{" 
   + "  \"geodata\": [" 
   + "    {" 
   + "      \"id\": \"1\"," 
   + "      \"name\": \"Julie Sherman\","                  
   + "      \"gender\" : \"female\"," 
   + "      \"latitude\" : \"37.33774833333334\"," 
   + "      \"longitude\" : \"-121.88670166666667\""
   + "    }," 
   + "    {" 
   + "      \"id\": \"2\"," 
   + "      \"name\": \"Johnny Depp\","          
   + "      \"gender\" : \"male\"," 
   + "      \"latitude\" : \"37.336453\"," 
   + "      \"longitude\" : \"-121.884985\""
   + "    }" 
   + "  ]" 
   + "}"; 

  public static void main(final String[] argv) throws JSONException {
    final JSONObject obj = new JSONObject(JSON_DATA);
    final JSONArray geodata = obj.getJSONArray("geodata");
    final int n = geodata.length();
    for (int i = 0; i < n; ++i) {
      final JSONObject person = geodata.getJSONObject(i);
      System.out.println(person.getInt("id"));
      System.out.println(person.getString("name"));
      System.out.println(person.getString("gender"));
      System.out.println(person.getDouble("latitude"));
      System.out.println(person.getDouble("longitude"));
    }
  }
}

Here's the output:

C:\dev\scrap>java -cp json.jar;. ShowActivity

You need to add a vertical-align property to your two child div's.

If .small is always shorter, you need only apply the property to .small. However, if either could be tallest then you should apply the property to both .small and .big.

.container{ 
    border: 1px black solid;
    width: 320px;
    height: 120px;    
}

.small{
    display: inline-block;
    width: 40%;
    height: 30%;
    border: 1px black solid;
    background: aliceblue; 
    vertical-align: top;   
}

.big {
    display: inline-block;
    border: 1px black solid;
    width: 40%;
    height: 50%;
    background: beige; 
    vertical-align: top;   
}

Vertical align affects inline or table-cell box's, and there are a large nubmer of different values for this property. Please see https://developer.mozilla.org/en-US/docs/Web/CSS/vertical-align for more details.

1. Right click References and do Add Reference, then from Assemblies->Framework select System.Web.Extensions.
2. Now you should be able to add the following to your class file:

    using System.Web.Script.Serialization;

        {
            foreach (DataRow dr in dt.Rows)
            {
                if (dr != null)
                {
                    if (check == 0)
                    {
                        getInsert = "INSERT INTO [tblTemp]([firstName],[lastName],[Father],[Mother],[Category]" +
                                ",[sub_1],[sub_LG2])"+
                                " select '" + dr[0].ToString() + "','" + dr[1].ToString() + "','" + dr[2].ToString() + "','" + dr[3].ToString() + "','" + dr[4].ToString().Trim() + "','" + dr[5].ToString().Trim() + "','" + dr[6].ToString();

                        check += 1;
                    }
                    else
                    {
                        getInsert += " UNION ALL ";

                        getInsert += " select  '" + dr[0].ToString() + "','" + dr[1].ToString() + "','" + dr[2].ToString() + "','" + dr[3].ToString() + "','" + dr[4].ToString().Trim() + "','" + dr[5].ToString().Trim() + "','" + dr[6].ToString() ;

                        check++;
                    }
                }
            }
            result = common.ExecuteNonQuery(getInsert, DatabasesName, conn, tx);
        }
        else
        {
            throw new Exception("No row for insertion");
        }
        dt.Dispose();
    }
    catch (Exception ex)
    {
        dt.Dispose();
        throw new Exception("Please attach file in Proper format.");
    }
    return result;
} 

AStyle can be customized in great detail for C++ and Java (and others too)

This is a source code formatting tool.

clang-format is a powerful command line tool bundled with the clang compiler which handles even the most obscure language constructs in a coherent way.

It can be integrated with Visual Studio, Emacs, Vim (and others) and can format just the selected lines (or with git/svn to format some diff).

It can be configured with a variety of options listed here.

When using config files (named .clang-format) styles can be per directory - the closest such file in parent directories shall be used for a particular file.

Styles can be inherited from a preset (say LLVM or Google) and can later override different options

It is used by Google and others and is production ready.

Also look at the project UniversalIndentGUI. You can experiment with several indenters using it: AStyle, Uncrustify, GreatCode, ... and select the best for you. Any of them can be run later from a command line.

Uncrustify has a lot of configurable options. You'll probably need Universal Indent GUI (in Konstantin's reply) as well to configure it.

Add a file .jslintrc (or .jshintrc in the case of jshint) at the root of your project with the following content:

{
    "node": true
}

<script src="/assets/backend/js/html2canvas.min.js"></script>


<script>
    $("#download").on('click', function(){
        html2canvas($("#printform"), {
            onrendered: function (canvas) {
                var url = canvas.toDataURL();

                var triggerDownload = $("<a>").attr("href", url).attr("download", getNowFormatDate()+"????????.jpeg").appendTo("body");
                triggerDownload[0].click();
                triggerDownload.remove();
            }
        });
    })
</script>

quotation

Put the part from BEGIN....END{} inside a file and name it like my.awk.

And then execute it like below:

awk -f my.awk life.csv >output.txt

Also I see a field separator as ,. You can add that in the begin block of the .awk file as FS=","

also check this out, for example we wanna count t

echo "test" | awk -v RS='t' 'END{print NR-1}'

or in python

python -c 'print "this is for test".count("t")'

or even better, we can make our script dynamic with awk

echo 'test' | awk '{for (i=1 ; i<=NF ; i++) array[$i]++ } END{ for (char in array) print char,array[char]}' FS=""

in this case output is like this :

e 1
s 1
t 2

Since this is the de facto answer when dealing with quotes in bash, I'll add upon one more point missed in the answers above, when dealing with the arithmetic operators in the shell.

The bash shell supports two ways do arithmetic operation, one defined by the built-in let command and the $((..)) operator. The former evaluates an arithmetic expression while the latter is more of a compound statement.

It is important to understand that the arithmetic expression used with let undergoes word-splitting, pathname expansion just like any other shell commands. So proper quoting and escaping needs to be done.

See this example when using let

let 'foo = 2 + 1'
echo $foo
3

Using single quotes here is absolutely fine here, as there is no need for variable expansions here, consider a case of

bar=1
let 'foo = $bar + 1'

would fail miserably, as the $bar under single quotes would not expand and needs to be double-quoted as

let 'foo = '"$bar"' + 1'

This should be one of the reasons, the $((..)) should always be considered over using let. Because inside it, the contents aren't subject to word-splitting. The previous example using let can be simply written as

(( bar=1, foo = bar + 1 ))

Always remember to use $((..)) without single quotes

Though the $((..)) can be used with double-quotes, there is no purpose to it as the result of it cannot contain a content that would need the double-quote. Just ensure it is not single quoted.

printf '%d\n' '$((1+1))'
-bash: printf: $((1+1)): invalid number
printf '%d\n' $((1+1))
2
printf '%d\n' "$((1+1))"
2

May be in some special cases of using the $((..)) operator inside a single quoted string, you need to interpolate quotes in a way that the operator either is left unquoted or under double quotes. E.g. consider a case, when you are tying to use the operator inside a curl statement to pass a counter every time a request is made, do

curl http://myurl.com --data-binary '{"requestCounter":'"$((reqcnt++))"'}'

Notice the use of nested double-quotes inside, without which the literal string $((reqcnt++)) is passed to requestCounter field.

You can also use this

$user = User::whereEmail($email)->first();

Another way:

Regex.Replace(urlString, "www.(.+)", "$1");

Try this:

$mpdf->Output('my_filename.pdf','D'); 

because:

D - means Download
F - means File-save only

If you call it like this: $ python myfile.py var1 var2 var3

import sys

var1 = sys.argv[1]
var2 = sys.argv[2]
var3 = sys.argv[3]

Similar to arrays you also have sys.argv[0] which is always the current working directory.

Recursively delete all children of the file ...

public static void DeleteRecursive(File fileOrDirectory) {
    if (fileOrDirectory.isDirectory()) {
        for (File child : fileOrDirectory.listFiles()) {
            DeleteRecursive(child);
        }
    }

    fileOrDirectory.delete();
}

background-size: contain; 

suits me

Each controller has it's own scope(s) so that's causing your issue.

Having two controllers that want access to the same data is a classic sign that you want a service. The angular team recommends thin controllers that are just glue between views and services. And specifically- "services should hold shared state across controllers".

Happily, there's a nice 15-minute video describing exactly this (controller communication via services): video

One of the original author's of Angular, Misko Hevery, discusses this recommendation (of using services in this situation) in his talk entitled Angular Best Practices (skip to 28:08 for this topic, although I very highly recommended watching the whole talk).

You can use events, but they are designed just for communication between two parties that want to be decoupled. In the above video, Misko notes how they can make your app more fragile. "Most of the time injecting services and doing direct communication is preferred and more robust". (Check out the above link starting at 53:37 to hear him talk about this)

As of Swift 1.1, you can directly pass String to const char * parameter.

import Foundation

let str = "123.4567"
let num = atof(str) // -> 123.4567

atof("123.4567fubar") // -> 123.4567

If you don't like deprecated atof:

strtod("765.4321", nil) // -> 765.4321

One caveat: the behavior of conversion is different from NSString.doubleValue.

atof and strtod accept 0x prefixed hex string:

atof("0xffp-2") // -> 63.75
atof("12.3456e+2") // -> 1,234.56
atof("nan") // -> (not a number)
atof("inf") // -> (+infinity)

If you prefer .doubleValue behavior, we can still use CFString bridging:

let str = "0xff"
atof(str)                      // -> 255.0
strtod(str, nil)               // -> 255.0
CFStringGetDoubleValue(str)    // -> 0.0
(str as NSString).doubleValue  // -> 0.0

I guess the uname answer is unbeatable, mainly in terms of cleanliness.

Although it takes a ridiculous time to execute, I found that testing for specific files presence also gives me good and quicker results, since I'm not invoking an executable:

So,

[ -f /usr/bin/cygwin1.dll ] && echo Yep, Cygwin running

just uses a quick Bash file presence check. As I'm on Windows right now, I can't tell you any specific files for Linuxes and Mac OS X from my head, but I'm pretty sure they do exist. :-)

        String input = "";
        int inputInteger = 0;
        BufferedReader br    = new BufferedReader(new InputStreamReader (System.in));

        System.out.println("Enter the radious: ");
        try {
            input = br.readLine();
            inputInteger = Integer.parseInt(input);
        } catch (NumberFormatException e) {
            System.out.println("Please Enter An Integer");
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        float area = (float) (3.14*inputInteger*inputInteger);
        System.out.println("Area = "+area);

javac command does not follow a recursive compilation process, so you have either specify each directory when running command, or provide a text file with directories you want to include:

javac -classpath "${CLASSPATH}" @java_sources.txt

git add .
git commit -m "initial commit"
git config --local credential.helper ""
git push https://github.com/youraccount/repo.git --all

After this push command, a username password prompt will be opened.

Many people had difficulty in using this keyword when we have iteration of Drop-downs with same elements but different values or say as Multi line data in USER INTERFACE. : Here is the code snippet : $(this).find('option[value=yourvalue]');

Hope you got this.

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

@echo off
setlocal EnableExtensions EnableDelayedExpansion

These steps worked for me on several Systems using Ubuntu 16.04, Apache 2.4, MariaDB, PDO

1. log into MYSQL as root

   mysql -u root
   

2. Grant privileges. To a new user execute:

   CREATE USER 'newuser'@'localhost' IDENTIFIED BY 'password';
   GRANT ALL PRIVILEGES ON *.* TO 'newuser'@'localhost';
   FLUSH PRIVILEGES;
   

   UPDATE for Google Cloud Instances

   MySQL on Google Cloud seem to require an alternate command (mind the backticks).

   GRANT ALL PRIVILEGES ON `%`.* TO 'newuser'@'localhost';
   

3. bind to all addresses:

   The easiest way is to comment out the line in your /etc/mysql/mariadb.conf.d/50-server.cnf or /etc/mysql/mysql.conf.d/mysqld.cnf file, depending on what system you are running:

   #bind-address = 127.0.0.1 
   

4. exit mysql and restart mysql

   exit
   service mysql restart
   

By default it binds only to localhost, but if you comment the line it binds to all interfaces it finds. Commenting out the line is equivalent to bind-address=*.

To check the binding of mysql service execute as root:

netstat -tupan | grep mysql

You could also create something that would be similar to a value object (vo);

SomeModelClassNameVO.js;

function SomeModelClassNameVO(name,id) {
    this.name = name;
    this.id = id;
}

Than you can just do;

   var someModelClassNameVO = new someModelClassNameVO('name',1);
   console.log(someModelClassNameVO.name);

Probably a duplicate of this post: A customized input text box in html/html5

input {_x000D_
  border: 0;_x000D_
  outline: 0;_x000D_
  background: transparent;_x000D_
  border-bottom: 1px solid black;_x000D_
}

The exception indicates a problem with the unobtrusive JavaScript validation mode. This issue is not Sitefinity specific and occurs in any standard ASP.NET applications when the project targets .NET 4.5 framework and the pre-4.5 validation is not enabled in the web.config file.

Open the web.config file and make sure that there is a ValidationSettings:UnobtrusiveValidationMode in the app settings:

<appSettings>
  <add key="ValidationSettings:UnobtrusiveValidationMode" value="None" />
</appSettings>

Since this would be a common task I would suggest wrapping a switch/case inside of a function call.

function getVocationName($vocation){
    switch($vocation){
        case 1: return "Sorcerer";
        case 2: return 'Druid';
        case 3: return 'Paladin';
        case 4: return 'Knight';
        case 5: return 'Master Sorcerer';
        case 6: return 'Elder Druid';
        case 7: return 'Royal Paladin';
        default: return 'Elite Knight';
    }
}

echo getVocationName($result->vocation);

Since filenames in UNIX may contain newlines (yes, newlines), wc -l might count too many files. I would print a dot for every file and then count the dots:

find DIR_NAME -type f -printf "." | wc -c

Worth mentioning that since version 1.4, Java had the classes java.beans.XMLEncoder and java.beans.XMLDecoder. These classes perform XML encoding which is at least very comparable to XML Serialization and in some circumstances might do the trick for you.

If your class sticks to the JavaBeans specification for its getters and setters, this method is straightforward to use and you don't need a schema. With the following caveats:

• As with normal Java serialization
  • coding and decoding run over a InputStream and OutputStream
  • the process uses the familar writeObject and readObject methods
• In contrast to normal Java serialization
  • the encoding but also decoding causes constructors and initializers to be invoked
  • encoding and decoding work regardless if your class implements Serializable or not
  • transient modifiers are not taken into account
  • works only for public classes, that have public constructors

For example, take the following declaration:

public class NPair {
  public NPair() { }
  int number1 = 0;
  int number2 = 0;
  public void setNumber1(int value) { number1 = value;}
  public int getNumber1() { return number1; }
  public void setNumber2(int value) { number2 = value; }
  public int getNumber2() {return number2;}
}

Executing this code:

NPair fe = new NPair();
fe.setNumber1(12);
fe.setNumber2(13);
FileOutputStream fos1 = new FileOutputStream("d:\\ser.xml");
java.beans.XMLEncoder xe1 = new java.beans.XMLEncoder(fos1);
xe1.writeObject(fe);
xe1.close();

Would result in the following file:

<?xml version="1.0" encoding="UTF-8"?>
<java version="1.7.0_02" class="java.beans.XMLDecoder">
 <object class="NPair">
  <void property="number1">
   <int>12</int>
  </void>
  <void property="number2">
   <int>13</int>
  </void>
 </object>
</java>

Try gcc -c -I/home/me/development/skia sample.c.

Something like...

Minutes.minutesBetween(getStart(), getEnd()).getMinutes();

You have to add another list:

list[:0]=['foo']

I always assumed the ! just indicated that the hash fragment that followed corresponded to a URL, with ! taking the place of the site root or domain. It could be anything, in theory, but it seems the Google AJAX Crawling API likes it this way.

The hash, of course, just indicates that no real page reload is occurring, so yes, it’s for AJAX purposes. Edit: Raganwald does a lovely job explaining this in more detail.

load the image by using following syntax:-

from keras.preprocessing import image

X_test=image.load_img('four.png',target_size=(28,28),color_mode="grayscale"); #loading image and then convert it into grayscale and with it's target size 
X_test=image.img_to_array(X_test); #convert image into array

I second jdk's answer: any public static member of any class of your application can be considered as a "global variable".

However, do note that this is an ASP.NET application, and as such, it's a multi-threaded context for your global variables. Therefore, you should use some locking mechanism when you update and/or read the data to/from these variables. Otherwise, you might get your data in a corrupted state.

One more way/syntax to do it is: git log -S "word"
Like this you can search for example git log -S "with whitespaces and stuff @/#ü !"

The correct format for IE8 is:

  $("#ActionBox").css({ 'margin-top': '10px' });  

with this work.

That's the error you get when a function makes too many recursive calls to itself. It might be doing this because the base case is never met (and therefore it gets stuck in an infinite loop) or just by making an large number of calls to itself. You could replace the recursive calls with while loops.

If you happen to process the value with some string function before saving, make sure the function can properly handle multibyte characters. String functions that cannot do that and are, say, attempting to truncate might split one of the single multibyte characters in the middle, and that can cause such string error situations.

In PHP for instance, you would need to switch from substr to mb_substr.

Double the backslashes in the path, like this:

driver.findElement(browsebutton).sendKeys("C:\\Users\\Desktop\\Training\\Training.jpg");

The documentation (https://angular.io/guide/template-syntax#!#star-template) gives the following example. Say we have template code like this:

<hero-detail *ngIf="currentHero" [hero]="currentHero"></hero-detail>

Before it will be rendered, it will be "de-sugared". That is, the asterix notation will be transcribed to the notation:

<template [ngIf]="currentHero">
  <hero-detail [hero]="currentHero"></hero-detail>
</template>

If 'currentHero' is truthy this will be rendered as

<hero-detail> [...] </hero-detail>

But what if you want an conditional output like this:

<h1>Title</h1><br>
<p>text</p>

.. and you don't want the output be wrapped in a container.

You could write the de-sugared version directly like so:

<template [ngIf]="showContent">
  <h1>Title</h1>
  <p>text</p><br>
</template>

And this will work fine. However, now we need ngIf to have brackets [] instead of an asterix *, and this is confusing (https://github.com/angular/angular.io/issues/2303)

For that reason a different notation was created, like so:

<ng-container *ngIf="showContent"><br>
  <h1>Title</h1><br>
  <p>text</p><br>
</ng-container>

Both versions will produce the same results (only the h1 and p tag will be rendered). The second one is preferred because you can use *ngIf like always.

If I'm not mistaken, the default bean name of a bean declared with @Component is the name of its class its first letter in lower-case. This means that

@Component
public class SuggestionService {

declares a bean of type SuggestionService, and of name suggestionService. It's equivalent to

@Component("suggestionService")
public class SuggestionService {

or to

<bean id="suggestionService" .../>

You're redefining another bean of the same type, but with a different name, in the XML:

<bean id="SuggestionService" class="com.hp.it.km.search.web.suggestion.SuggestionService">
    ...
</bean>

So, either specify the name of the bean in the annotation to be SuggestionService, or use the ID suggestionService in the XML (don't forget to also modify the <ref> element, or to remove it, since it isn't needed). In this case, the XML definition will override the annotation definition.

Use REN Command

Ren is for rename

ren ( where the file is located ) ( the new name )

example

ren C:\Users\&username%\Desktop\aaa.txt bbb.txt

it will change aaa.txt to bbb.txt

Your code will be :

ren (file located)AAA_a001.jpg a001.AAA.jpg

ren (file located)BBB_a002.jpg a002.BBB.jpg

ren (file located)CCC_a003.jpg a003.CCC.jpg

and so on

IT WILL NOT WORK IF THERE IS SPACES!

Hope it helps :D

<ui:include>

Most basic way is <ui:include>. The included content must be placed inside <ui:composition>.

Kickoff example of the master page /page.xhtml:

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title>Include demo</title>
    </h:head>
    <h:body>
        <h1>Master page</h1>
        <p>Master page blah blah lorem ipsum</p>
        <ui:include src="/WEB-INF/include.xhtml" />
    </h:body>
</html>

The include page /WEB-INF/include.xhtml (yes, this is the file in its entirety, any tags outside <ui:composition> are unnecessary as they are ignored by Facelets anyway):

<ui:composition 
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h2>Include page</h2>
    <p>Include page blah blah lorem ipsum</p>
</ui:composition>
  

This needs to be opened by /page.xhtml. Do note that you don't need to repeat <html>, <h:head> and <h:body> inside the include file as that would otherwise result in invalid HTML.

You can use a dynamic EL expression in <ui:include src>. See also How to ajax-refresh dynamic include content by navigation menu? (JSF SPA).

<ui:define>/<ui:insert>

A more advanced way of including is templating. This includes basically the other way round. The master template page should use <ui:insert> to declare places to insert defined template content. The template client page which is using the master template page should use <ui:define> to define the template content which is to be inserted.

Master template page /WEB-INF/template.xhtml (as a design hint: the header, menu and footer can in turn even be <ui:include> files):

<!DOCTYPE html>
<html lang="en"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">
    <h:head>
        <title><ui:insert name="title">Default title</ui:insert></title>
    </h:head>
    <h:body>
        <div id="header">Header</div>
        <div id="menu">Menu</div>
        <div id="content"><ui:insert name="content">Default content</ui:insert></div>
        <div id="footer">Footer</div>
    </h:body>
</html>

Template client page /page.xhtml (note the template attribute; also here, this is the file in its entirety):

<ui:composition template="/WEB-INF/template.xhtml"
    xmlns="http://www.w3.org/1999/xhtml"
    xmlns:f="http://xmlns.jcp.org/jsf/core"
    xmlns:h="http://xmlns.jcp.org/jsf/html"
    xmlns:ui="http://xmlns.jcp.org/jsf/facelets">

    <ui:define name="title">
        New page title here
    </ui:define>

    <ui:define name="content">
        <h1>New content here</h1>
        <p>Blah blah</p>
    </ui:define>
</ui:composition>

This needs to be opened by /page.xhtml. If there is no <ui:define>, then the default content inside <ui:insert> will be displayed instead, if any.

<ui:param>

You can pass parameters to <ui:include> or <ui:composition template> by <ui:param>.

<ui:include ...>
    <ui:param name="foo" value="#{bean.foo}" />
</ui:include>

<ui:composition template="...">
    <ui:param name="foo" value="#{bean.foo}" />
    ...
</ui:composition >

Inside the include/template file, it'll be available as #{foo}. In case you need to pass "many" parameters to <ui:include>, then you'd better consider registering the include file as a tagfile, so that you can ultimately use it like so <my:tagname foo="#{bean.foo}">. See also When to use <ui:include>, tag files, composite components and/or custom components?

You can even pass whole beans, methods and parameters via <ui:param>. See also JSF 2: how to pass an action including an argument to be invoked to a Facelets sub view (using ui:include and ui:param)?

Design hints

The files which aren't supposed to be publicly accessible by just entering/guessing its URL, need to be placed in /WEB-INF folder, like as the include file and the template file in above example. See also Which XHTML files do I need to put in /WEB-INF and which not?

There doesn't need to be any markup (HTML code) outside <ui:composition> and <ui:define>. You can put any, but they will be ignored by Facelets. Putting markup in there is only useful for web designers. See also Is there a way to run a JSF page without building the whole project?

The HTML5 doctype is the recommended doctype these days, "in spite of" that it's a XHTML file. You should see XHTML as a language which allows you to produce HTML output using a XML based tool. See also Is it possible to use JSF+Facelets with HTML 4/5? and JavaServer Faces 2.2 and HTML5 support, why is XHTML still being used.

CSS/JS/image files can be included as dynamically relocatable/localized/versioned resources. See also How to reference CSS / JS / image resource in Facelets template?

You can put Facelets files in a reusable JAR file. See also Structure for multiple JSF projects with shared code.

For real world examples of advanced Facelets templating, check the src/main/webapp folder of Java EE Kickoff App source code and OmniFaces showcase site source code.

There's this Explorer Exclude extension that exactly does this. https://marketplace.visualstudio.com/items?itemName=RedVanWorkshop.explorer-exclude-vscode-extension

It adds an option to hide current folder/file to the right click menu. It also adds a vertical tab Hidden Items to explorer menu where you can see currently hidden files & folders and can toggle them easily.

You can just forgo the quotes for alphanumeric attributes:

echo "<font color=red> XHTML is not a thing anymore. </font>";
echo "<div class=editorial-note> There, I said it. </div>";

Is perfectly valid in HTML, and though still shunned, absolutely en vogue since HTML5.

CAVEATS

• It's only valid for mostly alphanumeric and dash combinations.
• Never ever do this with user input appended to attributes (those need quoting and htmlspecialchars or some whitelisting).
• See also: When the attribute value can remain unquoted in HTML5
• In other news: <font> specifically is somewhat outdated however.

If you don't want to add a dependency on Guava (per Michael's answer) then this comparator is equivalent:

private static Comparator<String> ALPHABETICAL_ORDER = new Comparator<String>() {
    public int compare(String str1, String str2) {
        int res = String.CASE_INSENSITIVE_ORDER.compare(str1, str2);
        if (res == 0) {
            res = str1.compareTo(str2);
        }
        return res;
    }
};

Collections.sort(list, ALPHABETICAL_ORDER);

And I think it is just as easy to understand and code ...

The last 4 lines of the method can written more concisely as follows:

        return (res != 0) ? res : str1.compareTo(str2);

Try

document.head.innerHTML += '<meta http-equiv="X-UA-..." content="IE=edge">'

You can use PowerShell as well; this is what I did. As I needed to download a file based on a pattern I dynamically created a command file and then let ftp do the rest.

I used basic PowerShell commands. I did not need to download any additional components. I first checked if the requisite number of files existed. If they I invoked the FTP the second time with an Mget. I run this from a Windows Server 2008 connecting to a Windows XP remote server.

function make_ftp_command_file($p_file_pattern,$mget_flag)
{
    # This function dynamically prepares the FTP file.
    # The file needs to be prepared daily because the
    # pattern changes daily.
    # PowerShell default encoding is Unicode.
    # Unicode command files are not compatible with FTP so
    # we need to make sure we create an ASCII file.

    write-output "USER" | out-file -filepath C:\fc.txt -encoding ASCII
    write-output "ftpusername" | out-file -filepath C:\fc.txt -encoding ASCII -Append
    write-output "password" | out-file -filepath C:\fc.txt -encoding ASCII -Append
    write-output "ASCII" | out-file -filepath C:\fc.txt -encoding ASCII -Append
    If ($mget_flag -eq "Y")
    {
        write-output "prompt" | out-file -filepath C:\fc.txt -encoding ASCII -Append
        write-output "mget $p_file_pattern" | out-file -filepath C:\fc.txt -encoding ASCII -Append
    }
    else
    {
        write-output "ls $p_file_pattern" | out-file -filepath C:\fc.txt -encoding ASCII -Append
    }

    write-output quit | out-file -filepath C:\fc.txt -encoding ASCII -Append
}

                            string migrationName = item.GetCustomAttributes<MigrationAttribute>().First().Id;
                            var version = typeof(Migration).Assembly.GetName().Version;
                            string efVersion = $"{version.Major}.{version.Minor}.{version.Build}";

There are three parts:

1. Add a 'shebang' at the top of your script which tells how to execute your script
2. Give the script 'run' permissions.
3. Make the script in your PATH so you can run it from anywhere.

Adding a shebang

You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:

#!path/to/interpretter

To find the path to your python interpretter on your machine you can run the command:

which python

This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:

#!/usr/bin/python

Run Permissions

You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:

chmod +x myscript.py

Add the script to your path

The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:

echo $PATH

This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:

which <commandname>

Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:

export PATH=/my/directory/with/pythonscript:$PATH

Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile

The most commonly used type parameter names are:

E - Element (used extensively by the Java Collections Framework)
K - Key
N - Number
T - Type
V - Value
S,U,V etc. - 2nd, 3rd, 4th types

You'll see these names used throughout the Java SE API

Not every language supports reflection, but the principles are usually the same in languages that support it.

Reflection is the ability to "reflect" on the structure of your program. Or more concrete. To look at the objects and classes you have and programmatically get back information on the methods, fields, and interfaces they implement. You can also look at things like annotations.

It's useful in a lot of situations. Everywhere you want to be able to dynamically plug in classes into your code. Lots of object relational mappers use reflection to be able to instantiate objects from databases without knowing in advance what objects they're going to use. Plug-in architectures is another place where reflection is useful. Being able to dynamically load code and determine if there are types there that implement the right interface to use as a plugin is important in those situations.

You can split date month year from current date as follows:

DateTime todaysDate = DateTime.Now.Date;

Day:

int day = todaysDate.Day;

Month:

int month = todaysDate.Month;

Year:

int year = todaysDate.Year;

Execute function FetchData() once after 1000 milliseconds:

setTimeout(FetchData,1000);

Execute function FetchData() repeatedly every 1000 milliseconds:

setInterval(FetchData,1000);

A solution i'd go with that's fine for 32-bits, is the code the end of this answer, which is from developer.mozilla.org(MDN), but with some lines added for A)formatting and B)checking that the number is in range.

Some suggested x.toString(2) which doesn't work for negatives, it just sticks a minus sign in there for them, which is no good.

Fernando mentioned a simple solution of (x>>>0).toString(2); which is fine for negatives, but has a slight issue when x is positive. It has the output starting with 1, which for positive numbers isn't proper 2s complement.

Anybody that doesn't understand the fact of positive numbers starting with 0 and negative numbers with 1, in 2s complement, could check this SO QnA on 2s complement. What is “2's Complement”?

A solution could involve prepending a 0 for positive numbers, which I did in an earlier revision of this answer. And one could accept sometimes having a 33bit number, or one could make sure that the number to convert is within range -(2^31)<=x<2^31-1. So the number is always 32bits. But rather than do that, you can go with this solution on mozilla.org

Patrick's answer and code is long and apparently works for 64-bit, but had a bug that a commenter found, and the commenter fixed patrick's bug, but patrick has some "magic number" in his code that he didn't comment about and has forgotten about and patrick no longer fully understands his own code / why it works.

Annan had some incorrect and unclear terminology but mentioned a solution by developer.mozilla.org https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators This works for 32-bit numbers.

The code is pretty compact, a function of three lines.

But I have added a regex to format the output in groups of 8 bits. Based on How to print a number with commas as thousands separators in JavaScript (I just amended it from grouping it in 3s right to left and adding commas, to grouping in 8s right to left, and adding spaces)

And, while mozilla made a comment about the size of nMask(the number fed in)..that it has to be in range, they didn't test for or throw an error when the number is out of range, so i've added that.

I'm not sure why they named their parameter 'nMask' but i'll leave that as is.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Operators/Bitwise_Operators

You have some errors in your code:

1. Use myArray[i].push( 0 ); to add a new column. Your code (myArray[i][j].push(0);) would work in a 3-dimensional array as it tries to add another element to an array at position [i][j].
2. You only expand (col-d)-many columns in all rows, even in those, which haven't been initialized yet and thus have no entries so far.

One correct, although kind of verbose version, would be the following:

var r = 3; //start from rows 3

var rows = 8;
var cols = 7;

// expand to have the correct amount or rows
for( var i=r; i<rows; i++ ) {
  myArray.push( [] );
}

// expand all rows to have the correct amount of cols
for (var i = 0; i < rows; i++)
{
    for (var j =  myArray[i].length; j < cols; j++)
    {
        myArray[i].push(0);
    }
}

Solution based on @Elnoor answer, but working with multiple file upload form input and without the "fakepath hack":

HTML:

<div class="custom-file">
    <input id="logo" type="file" class="custom-file-input" multiple>
    <label for="logo" class="custom-file-label text-truncate">Choose file...</label>
</div>

JS:

$('input[type="file"]').on('change', function () {
    let filenames = [];
    let files = document.getElementById('health_claim_file_form_files').files;

    for (let i in files) {
        if (files.hasOwnProperty(i)) {
            filenames.push(files[i].name);
        }
    }

    $(this).next('.custom-file-label').addClass("selected").html(filenames.join(',    '));
});

If the purpose is to obtain a bitmap, this is very simple:

Canvas canvas = new Canvas();
canvas.setBitmap(image);
canvas.drawBitmap(image2, new Matrix(), null);

In the end, image will contain the overlap of image and image2.

As I understand your question..

From Java List class you have to methods add(E e) and get(int position).

add(E e)

Appends the specified element to the end of this list (optional operation).

get(int index)

Returns the element at the specified position in this list.

Example:

List<String> myString = new ArrayList<String>();

// How you add your data in string list
myString.add("Test 1");
myString.add("Test 2");
myString.add("Test 3");
myString.add("Test 4");

// retrieving data from string list array in for loop
for (int i=0;i < myString.size();i++)
{
  Log.i("Value of element "+i,myString.get(i));
}

But efficient way to iterate thru loop

for (String value : myString)
{
  Log.i("Value of element ",value);
}

In reading through Beazley & Jones PCB, I have stumbled on an explicit and practical use-case for __getattr__ that helps answer the "when" part of the OP's question. From the book:

"The __getattr__() method is kind of like a catch-all for attribute lookup. It's a method that gets called if code tries to access an attribute that doesn't exist." We know this from the above answers, but in PCB recipe 8.15, this functionality is used to implement the delegation design pattern. If Object A has an attribute Object B that implements many methods that Object A wants to delegate to, rather than redefining all of Object B's methods in Object A just to call Object B's methods, define a __getattr__() method as follows:

def __getattr__(self, name):
    return getattr(self._b, name)

where _b is the name of Object A's attribute that is an Object B. When a method defined on Object B is called on Object A, the __getattr__ method will be invoked at the end of the lookup chain. This would make code cleaner as well, since you do not have a list of methods defined just for delegating to another object.

As you surmise, it is to do with the connection string being in app.config of the class library.

Copy the entry from the class app.config to the container's app.config or web.config file

I would like to note, that setting the 'checked' attribute to a non-empty string leads to a checked box.

So if you set the 'checked' attribute to "false", the checkbox will be checked. I had to set the value to the empty string, null or the boolean value false in order to make sure the checkbox was not checked.

In Java 8 it can be done as: Base64.getEncoder().encodeToString(string.getBytes(StandardCharsets.UTF_8))

Here is a short, self-contained complete example:

import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class Temp {
    public static void main(String... args) throws Exception {
        final String s = "old crow medicine show";
        final byte[] authBytes = s.getBytes(StandardCharsets.UTF_8);
        final String encoded = Base64.getEncoder().encodeToString(authBytes);
        System.out.println(s + " => " + encoded);
    }
}

Output:

old crow medicine show => b2xkIGNyb3cgbWVkaWNpbmUgc2hvdw==

Try this

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="1" />

if you want 0 or 1 "description" elements, Or

<xs:element name="description" type="xs:string" minOccurs="0" maxOccurs="unbounded" />

if you want 0 to infinity number of "description" elements.

With async actions (timers, ajax) you can override the property isDefaultPrevented like this:

$('a').click(function(evt){
  e.preventDefault();

  // in async handler (ajax/timer) do these actions:
  setTimeout(function(){
    // override prevented flag to prevent jquery from discarding event
    evt.isDefaultPrevented = function(){ return false; }
    // retrigger with the exactly same event data
    $(this).trigger(evt);
  }, 1000);
}

This is most complete way of retriggering the event with the exactly same data.

Use putty. Put install directory path in environment values (PATH), and restart your PC if required.

Open cmd (command prompt) and type

C:/> pscp "C:\Users/gsjha/Desktop/example.txt" user@host:/home/

It'll be copied to the system.

I suspect you're confused here because it's fundamentally confusing. To make things worse, the whole ours/theirs stuff switches roles (becomes backwards) when you are doing a rebase.

Ultimately, during a git merge, the "ours" branch refers to the branch you're merging into:

git checkout merge-into-ours

and the "theirs" branch refers to the (single) branch you're merging:

git merge from-theirs

and here "ours" and "theirs" makes some sense, as even though "theirs" is probably yours anyway, "theirs" is not the one you were on when you ran git merge.

While using the actual branch name might be pretty cool, it falls apart in more complex cases. For instance, instead of the above, you might do:

git checkout ours
git merge 1234567

where you're merging by raw commit-ID. Worse, you can even do this:

git checkout 7777777    # detach HEAD
git merge 1234567       # do a test merge

in which case there are no branch names involved!

I think it's little help here, but in fact, in gitrevisions syntax, you can refer to an individual path in the index by number, during a conflicted merge

git show :1:README
git show :2:README
git show :3:README

Stage #1 is the common ancestor of the files, stage #2 is the target-branch version, and stage #3 is the version you are merging from.

The reason the "ours" and "theirs" notions get swapped around during rebase is that rebase works by doing a series of cherry-picks, into an anonymous branch (detached HEAD mode). The target branch is the anonymous branch, and the merge-from branch is your original (pre-rebase) branch: so "--ours" means the anonymous one rebase is building while "--theirs" means "our branch being rebased".

As for the gitattributes entry: it could have an effect: "ours" really means "use stage #2" internally. But as you note, it's not actually in place at the time, so it should not have an effect here ... well, not unless you copy it into the work tree before you start.

Also, by the way, this applies to all uses of ours and theirs, but some are on a whole file level (-s ours for a merge strategy; git checkout --ours during a merge conflict) and some are on a piece-by-piece basis (-X ours or -X theirs during a -s recursive merge). Which probably does not help with any of the confusion.

I've never come up with a better name for these, though. And: see VonC's answer to another question, where git mergetool introduces yet more names for these, calling them "local" and "remote"!

Just use

 as.Date("2001-01-01") + 45

from base R, or date functionality in one of the many contributed packages. My RcppBDT package wraps functionality from Boost Date_Time including things like 'date of third Wednesday' in a given month.

Edit: And egged on by @Andrie, here is a bit more from RcppBDT (which is mostly a test case for Rcpp modules, really).

As others have mentioned here, conventions should be a tool for adding to the ease of use and readability. Not as a shackle or a club to torture developers.

That said, my personal preference is to use singular names for both tables and columns. This probably comes from my programming background. Class names are generally singular unless they are some sort of collection. In my mind I am storing or reading individual records in the table in question, so singular makes sense to me.

This practice also allows me to reserve plural table names for those that store many-to-many relationships between my objects.

I try to avoid reserved words in my table and column names, as well. In the case in question here it makes more sense to go counter to the singular convention for Users to avoid the need to encapsulate a table that uses the reserved word of User.

I like using prefixes in a limited manner (tbl for table names, sp_ for proc names, etc), though many believe this adds clutter. I also prefer CamelBack names to underscores because I always end up hitting the + instead of _ when typing the name. Many others disagree.

Here is another good link for naming convention guidelines: http://www.xaprb.com/blog/2008/10/26/the-power-of-a-good-sql-naming-convention/

Remember that the most important factor in your convention is that it make sense to the people interacting with the database in question. There is no "One Ring to Rule Them All" when it comes to naming conventions.

If you're doing some performance tuning it's often recommended to set both -XX:PermSize and -XX:MaxPermSize to the same value to increase JVM efficiency.

Here is some information:

1. Support for large page heap on x86 and amd64 platforms
2. Java Support for Large Memory Pages
3. Setting the Permanent Generation Size

You can also specify -XX:+CMSClassUnloadingEnabled to enable class unloading option if you are using CMS GC. It may help to decrease the probability of Java.lang.OutOfMemoryError: PermGen space

Your broadcast receiver must specify android:exported="true" to receive broadcasts created outside your own application. My broadcast receiver is defined in the manifest as follows:

<receiver
    android:name=".IncomingSmsBroadcastReceiver"
    android:enabled="true"
    android:exported="true" >
    <intent-filter>
        <action android:name="android.provider.Telephony.SMS_RECEIVED" />
    </intent-filter>
</receiver>

As noted below, exported="true" is the default, so you can omit this line. I've left it in so that the discussion comments make sense.

I had the same problem: I love the resolve object, but that only works for the content of ng-view. What if you have controllers (for top-level nav, let's say) that exist outside of ng-view and which need to be initialized with data before the routing even begins to happen? How do we avoid mucking around on the server-side just to make that work?

Use manual bootstrap and an angular constant. A naiive XHR gets you your data, and you bootstrap angular in its callback, which deals with your async issues. In the example below, you don't even need to create a global variable. The returned data exists only in angular scope as an injectable, and isn't even present inside of controllers, services, etc. unless you inject it. (Much as you would inject the output of your resolve object into the controller for a routed view.) If you prefer to thereafter interact with that data as a service, you can create a service, inject the data, and nobody will ever be the wiser.

Example:

//First, we have to create the angular module, because all the other JS files are going to load while we're getting data and bootstrapping, and they need to be able to attach to it.
var MyApp = angular.module('MyApp', ['dependency1', 'dependency2']);

// Use angular's version of document.ready() just to make extra-sure DOM is fully 
// loaded before you bootstrap. This is probably optional, given that the async 
// data call will probably take significantly longer than DOM load. YMMV.
// Has the added virtue of keeping your XHR junk out of global scope. 
angular.element(document).ready(function() {

    //first, we create the callback that will fire after the data is down
    function xhrCallback() {
        var myData = this.responseText; // the XHR output

        // here's where we attach a constant containing the API data to our app 
        // module. Don't forget to parse JSON, which `$http` normally does for you.
        MyApp.constant('NavData', JSON.parse(myData));

        // now, perform any other final configuration of your angular module.
        MyApp.config(['$routeProvider', function ($routeProvider) {
            $routeProvider
              .when('/someroute', {configs})
              .otherwise({redirectTo: '/someroute'});
          }]);

        // And last, bootstrap the app. Be sure to remove `ng-app` from your index.html.
        angular.bootstrap(document, ['NYSP']);
    };

    //here, the basic mechanics of the XHR, which you can customize.
    var oReq = new XMLHttpRequest();
    oReq.onload = xhrCallback;
    oReq.open("get", "/api/overview", true); // your specific API URL
    oReq.send();
})

Now, your NavData constant exists. Go ahead and inject it into a controller or service:

angular.module('MyApp')
    .controller('NavCtrl', ['NavData', function (NavData) {
        $scope.localObject = NavData; //now it's addressable in your templates 
}]);

Of course, using a bare XHR object strips away a number of the niceties that $http or JQuery would take care of for you, but this example works with no special dependencies, at least for a simple get. If you want a little more power for your request, load up an external library to help you out. But I don't think it's possible to access angular's $http or other tools in this context.

Try redis, it is one of the cleanest and easiest solutions for applications to share data in a atomic way or if you have got some web server platform. Its very easy to setup, you will need a python redis client http://pypi.python.org/pypi/redis

I remember from Czech book about C: read the declaration that you start with the variable and go left. So for

char * const a;

you can read as: "a is variable of type constant pointer to char",

char const * a;

you can read as: "a is a pointer to constant variable of type char. I hope this helps.

Bonus:

const char * const a;

You will read as a is constant pointer to constant variable of type char.

Assume the following code:

import torch
import numpy as np
a = torch.tensor([1, 2, 3, 4, 5])

The following three calls have the exact same effect:

res_1 = a.unsqueeze(0)
res_2 = a.view(1, 5)
res_3 = a[np.newaxis,:]
res_1.shape == res_2.shape == res_3.shape == (1,5)  # Returns true

Notice that for any of the resulting tensors, if you modify the data in them, you are also modifying the data in a, because they don't have a copy of the data, but reference the original data in a.

res_1[0,0] = 2
a[0] == res_1[0,0] == 2  # Returns true

The other way of doing it would be using the resize_ in place operation:

a.shape == res_1.shape  # Returns false
a.reshape_((1, 5))
a.shape == res_1.shape # Returns true

Be careful of using resize_ or other in-place operation with autograd. See the following discussion: https://pytorch.org/docs/stable/notes/autograd.html#in-place-operations-with-autograd

Use

print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))

like this:

>>> my_string = "deadbeef"
>>> print " ".join("0x%s"%my_string[i:i+2] for i in range(0, len(my_string), 2))
0xde 0xad 0xbe 0xef
>>>

On an unrelated side note ... using string as a variable name even as an example variable name is very bad practice.

I think you should consider using IO.binread("/path/to/file") if you have a recent ruby interpreter (i.e. >= 1.9.2)

You could find IO class documentation here http://www.ruby-doc.org/core-2.1.2/IO.html

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

Notes:

• Put the following content in your configuration file.
• Name the configuration file log4j2.xml
• Put the log4j2.xml in a folder which is in the class-path (i.e. your source folder "src")
• Use Logger logger = LogManager.getLogger(); to initialize your logger
• I did set the immediateFlush="false" since this is better for SSD lifetime. If you need the log right away in your log-file remove the parameter or set it to true

In Visual Studio 2015 (community edition), System.Windows.Forms is not available and hence we can't use MessageBox.Show("text").

Use this Instead:

var Msg = new MessageDialog("Some String here", "Title of Message Box");    
await Msg.ShowAsync();

Note: Your function must be defined async to use above await Msg.ShowAsync().

You can also set a global ignore pattern in SVN's configuration file.

what about this

--// Convert NVARCHAR to DATETIME
DECLARE @date DATETIME = (SELECT convert(DATETIME, '2013-08-29 13:55:48', 120))
--// Convert DATETIME to custom NVARCHAR FORMAT
SELECT 
RIGHT('00'+ CAST(DAY(@date) AS NVARCHAR),2) + '-' +
RIGHT('00'+ CAST(MONTH(@date) AS NVARCHAR),2) + '-' + 
CAST(YEAR(@date) AS NVARCHAR) + ' ' + 
CAST(CONVERT(TIME,@date) AS NVARCHAR)

result: '29-08-2013 13:55:48.0000000'

  var data = JSON.stringify
            ({
            'StrContactDetails': Details,
            'IsPrimary': true
            })

<p> represents a paragraph and <div> represents a 'division', I suppose the main difference is that divs are semantically 'meaningless', where as a <p> is supposed to represent something relating to the text itself.

You wouldn't want to have nested <p>s for example, since that wouldn't make much semantic sense (except in the sense of quotations) Whereas people use nested <div>s for page layout.

According to Wikipedia

In HTML, the span and div elements are used where parts of a document cannot be semantically described by other HTML elements.

If the code for your jar library is on GitHub then importing into Android Studio is easy with JitPack.

Your will just need to add the repository to build.gradle:

allprojects{
 repositories {
    jcenter()
    maven { url "https://jitpack.io" }
 }
}

and then the library's GitHub repository as a dependency:

dependencies {
    // ...
    compile 'com.github.YourUsername:LibraryRepo:ReleaseTag'
}

JitPack acts as a maven repository and can be used like Maven Central. The nice thing is that you don't have to upload the jar manually. Behind the scenes JitPack will check out the code from GitHub and compile it. Therefore it works only if the repo has a build file in it (build.gradle).

There is also a guide on how to prepare an Android project.

You cannot concatenate a string with an int. You would need to convert your int to a string using the str function, or use formatting to format your output.

Change: -

print("Ok. Your balance is now at " + balanceAfterStrength + " skill points.")

to: -

print("Ok. Your balance is now at {} skill points.".format(balanceAfterStrength))

or: -

print("Ok. Your balance is now at " + str(balanceAfterStrength) + " skill points.")

or as per the comment, use , to pass different strings to your print function, rather than concatenating using +: -

print("Ok. Your balance is now at ", balanceAfterStrength, " skill points.")

Search all .npmrc file in your system.

Please verify that the path you have given is correct. If not please remove the incorrect path.

You can pass the tv_sec parameter to some of the formatting function. Have a look at gmtime, localtime(). Then look at snprintf.

This should fix a few edge-cases in kobe's answer:

function getQueryParam(url, key) {
  var queryStartPos = url.indexOf('?');
  if (queryStartPos === -1) {
    return;
  }
  var params = url.substring(queryStartPos + 1).split('&');
  for (var i = 0; i < params.length; i++) {
    var pairs = params[i].split('=');
    if (decodeURIComponent(pairs.shift()) == key) {
      return decodeURIComponent(pairs.join('='));
    }
  }
}

getQueryParam('http://example.com/form_image_edit.php?img_id=33', 'img_id');
// outputs "33"

There are two ways you can do this; with patch and with patch.object

Patch assumes that you are not directly importing the object but that it is being used by the object you are testing as in the following

#foo.py
def some_fn():
    return 'some_fn'

class Foo(object):
    def method_1(self):
        return some_fn()

#bar.py
import foo
class Bar(object):
    def method_2(self):
        tmp = foo.Foo()
        return tmp.method_1()

#test_case_1.py
import bar
from mock import patch

@patch('foo.some_fn')
def test_bar(mock_some_fn):
    mock_some_fn.return_value = 'test-val-1'
    tmp = bar.Bar()
    assert tmp.method_2() == 'test-val-1'
    mock_some_fn.return_value = 'test-val-2'
    assert tmp.method_2() == 'test-val-2'

If you are directly importing the module to be tested, you can use patch.object as follows:

#test_case_2.py
import foo
from mock import patch

@patch.object(foo, 'some_fn')
def test_foo(test_some_fn):
    test_some_fn.return_value = 'test-val-1'
    tmp = foo.Foo()
    assert tmp.method_1() == 'test-val-1'
    test_some_fn.return_value = 'test-val-2'
    assert tmp.method_1() == 'test-val-2'

In both cases some_fn will be 'un-mocked' after the test function is complete.

Edit: In order to mock multiple functions, just add more decorators to the function and add arguments to take in the extra parameters

@patch.object(foo, 'some_fn')
@patch.object(foo, 'other_fn')
def test_foo(test_other_fn, test_some_fn):
    ...

Note that the closer the decorator is to the function definition, the earlier it is in the parameter list.

You can try these some steps:

Stop Mysql Service 1st sudo /etc/init.d/mysql stop

Login as root without password sudo mysqld_safe --skip-grant-tables &

After login mysql terminal you should need execute commands more:

use mysql;

UPDATE mysql.user SET authentication_string=PASSWORD('solutionclub3@*^G'), plugin='mysql_native_password' WHERE User='root';

flush privileges;

sudo mysqladmin -u root -p -S /var/run/mysqld/mysqld.sock shutdown

After you restart your mysql server If you still facing error you must visit : Reset MySQL 5.7 root password Ubuntu 16.04

Simply:

// Default export (recommended)
export {default} from './MyClass' 

// Default export with alias
export {default as d1} from './MyClass' 

// In >ES7, it could be
export * from './MyClass'

// In >ES7, with alias
export * as d1 from './MyClass'

Or by functions names :

// export by function names
export { funcName1, funcName2, …} from './MyClass'

// export by aliases
export { funcName1 as f1, funcName2 as f2, …} from './MyClass'

how about some open/close safety.

Just tick "Automatically manage signing" in General -> Signing properties of the Target. It will create Development provisioning profile for you and running on the device will work.

Open command prompt (cmd.exe/git bash)

Recommended:

npm install -g typescript@latest

or

yarn global add typescript@latest  // if you use yarn package manager

This will install the latest typescript version if not already installed, otherwise it will update the current installation to the latest version.

And then verify which version is installed:

tsc -v

If you have typescript already installed you could also use the following command to update to latest version, but as commentators have reported and I confirm it that the following command does not update to latest (as of now [ Feb 10 '17])!

npm update -g typescript@latest

For the benefit of anyone else coming here by far the best thing to do is to update cx_Oracle to the latest version (6+). This version does not need LD_LIBRARY_PATH set at all.

Take a look at String.format. Note, however, that it takes format specifiers similar to those of C's printf family of functions -- for example:

String.format("Hello %s, %d", "world", 42);

Would return "Hello world, 42". You may find this helpful when learning about the format specifiers. Andy Thomas-Cramer was kind enough to leave this link in a comment below, which appears to point to the official spec. The most commonly used ones are:

• %s - insert a string
• %d - insert a signed integer (decimal)
• %f - insert a real number, standard notation

This is radically different from C#, which uses positional references with an optional format specifier. That means that you can't do things like:

String.format("The {0} is repeated again: {0}", "word");

... without actually repeating the parameter passed to printf/format. (see The Scrum Meister's comment below)

If you just want to print the result directly, you may find System.out.printf (PrintStream.printf) to your liking.

On Debian derivatives such as Ubuntu, use apt. Check the apt repository for the versions of Python available to you. Then, run a command similar to the following, substituting the correct package name:

sudo apt-get install python3

On Red Hat and derivatives, use yum. Check the yum repository for the versions of Python available to you. Then, run a command similar to the following, substituting the correct package name:

sudo yum install python36

On SUSE and derivatives, use zypper. Check the repository for the versions of Python available to you. Then. run a command similar to the following, substituting the correct package name:

sudo zypper install python3
