You can use the following code. It is similar to existing functions except that you can force special character count:

function random_string() {
    // 8 characters: 7 lower-case alphabets and 1 digit
    $character_sets = [
        ["count" => 7, "characters" => "abcdefghijklmnopqrstuvwxyz"],
        ["count" => 1, "characters" => "0123456789"]
    ];
    $temp_array = array();
    foreach ($character_sets as $character_set) {
        for ($i = 0; $i < $character_set["count"]; $i++) {
            $random = random_int(0, strlen($character_set["characters"]) - 1);
            $temp_array[] = $character_set["characters"][$random];
        }
    }
    shuffle($temp_array);
    return implode("", $temp_array);
}

If you are using Django and want to cache views, see Nikhil Kumar's answer.

But if you want to cache ANY function results, you can use django-cache-utils.

It reuses Django caches and provides easy to use cached decorator:

from cache_utils.decorators import cached

@cached(60)
def foo(x, y=0):
    print 'foo is called'
    return x+y

When I was doing the same query, I had hard time adjusting the solutions to my case, though all the previous answers have good insights.

Here is a solution when one has to acquire a list of unique objects, NOT strings. Let's say, one has a list of Record object. Record class has only properties of type String, NO property of type int. Here implementing hashCode() becomes difficult as hashCode() needs to return an int.

The following is a sample Record Class.

public class Record{

    String employeeName;
    String employeeGroup;

    Record(String name, String group){  
        employeeName= name;
        employeeGroup = group;    
    }
    public String getEmployeeName(){
        return employeeName;
    }
    public String getEmployeeGroup(){
        return employeeGroup;
    }

  @Override
    public boolean equals(Object o){
         if(o instanceof Record){
            if (((Record) o).employeeGroup.equals(employeeGroup) &&
                  ((Record) o).employeeName.equals(employeeName)){
                return true;
            }
         }
         return false;
    }

    @Override
    public int hashCode() { //this should return a unique code
        int hash = 3; //this could be anything, but I would chose a prime(e.g. 5, 7, 11 )
        //again, the multiplier could be anything like 59,79,89, any prime
        hash = 89 * hash + Objects.hashCode(this.employeeGroup); 
        return hash;
    }

As suggested earlier by others, the class needs to override both the equals() and the hashCode() method to be able to use HashSet.

Now, let's say, the list of Records is allRecord(List<Record> allRecord).

Set<Record> distinctRecords = new HashSet<>();

for(Record rc: allRecord){
    distinctRecords.add(rc);
}

This will only add the distinct Records to the Hashset, distinctRecords.

Hope this helps.

From man diff, you can use -y to do side-by-side.

-y, --side-by-side
       output in two columns

Hence, say:

diff -y /tmp/test1  /tmp/test2

Test

$ cat a                $ cat b
hello                  hello
my name                my name
is me                  is you

Let's compare them:

$ diff -y a b
hello                                                           hello
my name                                                         my name
is me                                                         | is you

Overloading a method (or function) in C++ is the ability for functions of the same name to be defined as long as these methods have different signatures (different set of parameters). Method overriding is the ability of the inherited class rewriting the virtual method of the base class.

a) In overloading, there is a relationship between methods available in the same class whereas in overriding, there a is relationship between a superclass method and subclass method.

(b) Overloading does not block inheritance from the superclass whereas overriding blocks inheritance from the superclass.

(c) In overloading, separate methods share the same name whereas in overriding, subclass method replaces the superclass.

(d) Overloading must have different method signatures whereas overriding must have same signature.

DECLARE @ReseedBit BIT = 
    COALESCE((SELECT SUM(CONVERT(BIGINT, ic.last_value))
                FROM sys.identity_columns ic
                INNER JOIN sys.tables t ON ic.object_id = t.object_id), 0)
DECLARE @Reseed INT =

Caveats: This is intended for use in reference data population situations where a DB is being initialized with enum type definition tables, where the ID values in those tables must always start at 1. The first time the DB is being created (e.g. during SSDT-DB publishing) @Reseed must be 0, but when resetting the data i.e. removing the data and re-inserting it, then @Reseed must be 1. So this code is intended for use in a stored procedure for resetting the DB data, which can be called manually but is also called from the post-deployment script in the SSDT-DB project. In that way the reference data inserts are only defined in one place but aren't restricted to be used only in post-deployment during publishing, they are also available for subsequent use (to support dev and automated test etc.) by calling the stored procedure to reset the DB back to a known good state.

Make sure that the node server to provide the bundle is running in the background. To run start the server use npm start or react-native start and keep the tab open during development

The default namespace in Python is "__main__". When you use import scipy, Python creates a separate namespace as your module name. The rule in Pyhton is: when you want to call an attribute from another namespaces you have to use the fully qualified attribute name.

You can simply make it by REGEX:

Form:

<form method="post" action="" enctype="multipart/form-data">
    <div class="uploadExtensionError" style="display: none">Only PDF allowed!</div>
    <input type="file" name="item_file" />
    <input type="submit" id='submit' value="submit"/>
</form>

And java script validation:

<script>
    $('#submit').click(function(event) {
        var val = $('input[type=file]').val().toLowerCase();
        var regex = new RegExp("(.*?)\.(pdf|docx|doc)$");
        if(!(regex.test(val))) {
            $('.uploadExtensionError').show();
            event.preventDefault();
        }
    });
</script>

Cheers!

Assuming test.sh is the shell script that you would want to execute

os.system("sh test.sh")

variable=$(ps -ef | awk '/[p]ort 10/ {print $12}')

The [p] is a neat trick to remove the search from showing from ps

@Jeremy If you post the output of ps -ef | grep "port 10", and what you need from the line, it would be more easy to help you getting correct syntax

If you're interested in seeing which specific headers a remote client is sending to your server, and you can cause the request to run a CGI script, then the simplest solution is to have your server script dump the environment variables into a file somewhere.

e.g. run the shell command "env > /tmp/headers" from within your script

Then, look for the environment variables that start with HTTP_...

You will see lines like:

HTTP_ACCEPT=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
HTTP_ACCEPT_ENCODING=gzip, deflate
HTTP_ACCEPT_LANGUAGE=en-US,en;q=0.5
HTTP_CACHE_CONTROL=max-age=0

Each of those represents a request header.

Note that the header names are modified from the actual request. For example, "Accept-Language" becomes "HTTP_ACCEPT_LANGUAGE", and so on.

int main(){
    int i=0;
    int a=0;
    for(i;i<5;i++,a++){
        printf("%d %d\n",a,i);
    } 
}

Here's some code taken from Kirk Evans Blog that demonstrates how to encode an image in C#;

//Load the picture from a file
Image picture = Image.FromFile(@"c:\temp\test.gif");

//Create an in-memory stream to hold the picture's bytes
System.IO.MemoryStream pictureAsStream = new System.IO.MemoryStream();
picture.Save(pictureAsStream, System.Drawing.Imaging.ImageFormat.Gif);

//Rewind the stream back to the beginning
pictureAsStream.Position = 0;
//Get the stream as an array of bytes
byte[] pictureAsBytes = pictureAsStream.ToArray();

//Create an XmlTextWriter to write the XML somewhere... here, I just chose
//to stream out to the Console output stream
System.Xml.XmlTextWriter writer = new System.Xml.XmlTextWriter(Console.Out);

//Write the root element of the XML document and the base64 encoded data
writer.WriteStartElement("w", "binData",
                         "http://schemas.microsoft.com/office/word/2003/wordml");

writer.WriteBase64(pictureAsBytes, 0, pictureAsBytes.Length);

writer.WriteEndElement();
writer.Flush();

//Response being your httpwebresponse
Dim str_StatusCode as String = CInt(Response.StatusCode)
Console.Writeline(str_StatusCode)

Alternately, if you are using SQL Server as your database you can get your GUID from the server instead. In TSQL:

//Retrive your key ID on the bases of GUID 

declare @ID as uniqueidentifier

SET @ID=NEWID()
insert into Sector(Sector,CID)

Values ('Diry7',@ID)


select SECTORID from sector where CID=@ID

The component solution and deep-clone solution have their advantages, but also have issues:

1. Sometimes you want to track changes in abstract data - it doesn't always make sense to build components around that data.

2. Deep-cloning your entire data structure every time you make a change can be very expensive.

I think there's a better way. If you want to watch all items in a list and know which item in the list changed, you can set up custom watchers on every item separately, like so:

var vm = new Vue({
  data: {
    list: [
      {name: 'obj1 to watch'},
      {name: 'obj2 to watch'},
    ],
  },
  methods: {
    handleChange (newVal) {
      // Handle changes here!
      console.log(newVal);
    },
  },
  created () {
    this.list.forEach((val) => {
      this.$watch(() => val, this.handleChange, {deep: true});
    });
  },
});

With this structure, handleChange() will receive the specific list item that changed - from there you can do any handling you like.

I have also documented a more complex scenario here, in case you are adding/removing items to your list (rather than only manipulating the items already there).

Use git branch --contains HEAD | tail -1 | xargs it also works for "detached HEAD" state.

Just dump the data in delimited-text format.

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

You need to use cell.Text = "#N/A" instead of cell.Value = "#N/A". The error in the cell is actually just text stored in the cell.

Three possible solutions come to my mind:

1. Reverse the order:

//convert the arr to list first
Collections.reverse(listWithNumbers);
System.out.print("Numbers in Descending Order: " + listWithNumbers);

2. Iterate backwards and print it:

Arrays.sort(arr);
System.out.print("Numbers in Descending Order: " );
for(int i = arr.length - 1; i >= 0; i--){
  System.out.print( " " +arr[i]);
}

3. Sort it with "oposite" comparator:

Arrays.sort(arr, new Comparator<Integer>(){
   int compare(Integer i1, Integer i2) {
      return i2 - i1;
   }
});
// or Collections.reverseOrder(), could be used instead
System.out.print("Numbers in Descending Order: " );
for(int i = 0; i < arr.length; i++){
  System.out.print( " " +arr[i]);
}

<input type="text" maxlength="5">

the maximum amount of letters that can be in the input is 5.

Just add this line as per your compileSdkVersion

buildToolsVersion "27.0.3"

Using url-loader, described here (SurviveJS - Loading Images), you can then use in your code :

import LogoImg from 'YOUR_PATH/logo.png';

and

<img src={LogoImg}/>

Edit: a precision, images are inlined in the js archive with this technique. It can be worthy for small images, but use the technique wisely.

You will first need to create a custom layout xml which will represent a single item in your list. You will add your two buttons to this layout along with any other items you want to display from your list.

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

<TextView
    android:id="@+id/list_item_string"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerVertical="true"
    android:layout_alignParentLeft="true"
    android:paddingLeft="8dp"
    android:textSize="18sp"
    android:textStyle="bold" /> 

<Button
    android:id="@+id/delete_btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_centerVertical="true"
    android:layout_marginRight="5dp"
    android:text="Delete" /> 

<Button
    android:id="@+id/add_btn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_toLeftOf="@id/delete_btn"
    android:layout_centerVertical="true"
    android:layout_marginRight="10dp"
    android:text="Add" />

</RelativeLayout>

Next you will need to create a Custom ArrayAdapter Class which you will use to inflate your xml layout, as well as handle your buttons and on click events.

public class MyCustomAdapter extends BaseAdapter implements ListAdapter { 
private ArrayList<String> list = new ArrayList<String>(); 
private Context context; 



public MyCustomAdapter(ArrayList<String> list, Context context) { 
    this.list = list; 
    this.context = context; 
} 

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

@Override
public Object getItem(int pos) { 
    return list.get(pos); 
} 

@Override
public long getItemId(int pos) { 
    return list.get(pos).getId();
    //just return 0 if your list items do not have an Id variable.
} 

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    View view = convertView;
    if (view == null) {
        LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
        view = inflater.inflate(R.layout.my_custom_list_layout, null);
    } 

    //Handle TextView and display string from your list
    TextView listItemText = (TextView)view.findViewById(R.id.list_item_string); 
    listItemText.setText(list.get(position)); 

    //Handle buttons and add onClickListeners
    Button deleteBtn = (Button)view.findViewById(R.id.delete_btn);
    Button addBtn = (Button)view.findViewById(R.id.add_btn);

    deleteBtn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) { 
            //do something
            list.remove(position); //or some other task
            notifyDataSetChanged();
        }
    });
    addBtn.setOnClickListener(new View.OnClickListener(){
        @Override
        public void onClick(View v) { 
            //do something
            notifyDataSetChanged();
        }
    });

    return view; 
} 
}

Finally, in your activity you can instantiate your custom ArrayAdapter class and set it to your listview.

public class MyActivity extends Activity { 

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

    //generate list
    ArrayList<String> list = new ArrayList<String>();
    list.add("item1");
    list.add("item2");

    //instantiate custom adapter
    MyCustomAdapter adapter = new MyCustomAdapter(list, this);

    //handle listview and assign adapter
    ListView lView = (ListView)findViewById(R.id.my_listview);
    lView.setAdapter(adapter);
}

Hope this helps!

I've updated the class using refs as all the solutions I see on here have things that are no longer supported or will soon be depreciated like ReactDOM.findDOMNode. Can be parent to a child component or a group of children :)

import React, { Component } from 'react';

class Draggable extends Component {

    constructor(props) {
        super(props);
        this.myRef = React.createRef();
        this.state = {
            counter: this.props.counter,
            pos: this.props.initialPos,
            dragging: false,
            rel: null // position relative to the cursor
        };
    }

    /*  we could get away with not having this (and just having the listeners on
     our div), but then the experience would be possibly be janky. If there's
     anything w/ a higher z-index that gets in the way, then you're toast,
     etc.*/
    componentDidUpdate(props, state) {
        if (this.state.dragging && !state.dragging) {
            document.addEventListener('mousemove', this.onMouseMove);
            document.addEventListener('mouseup', this.onMouseUp);
        } else if (!this.state.dragging && state.dragging) {
            document.removeEventListener('mousemove', this.onMouseMove);
            document.removeEventListener('mouseup', this.onMouseUp);
        }
    }

    // calculate relative position to the mouse and set dragging=true
    onMouseDown = (e) => {
        if (e.button !== 0) return;
        let pos = { left: this.myRef.current.offsetLeft, top: this.myRef.current.offsetTop }
        this.setState({
            dragging: true,
            rel: {
                x: e.pageX - pos.left,
                y: e.pageY - pos.top
            }
        });
        e.stopPropagation();
        e.preventDefault();
    }

    onMouseUp = (e) => {
        this.setState({ dragging: false });
        e.stopPropagation();
        e.preventDefault();
    }

    onMouseMove = (e) => {
        if (!this.state.dragging) return;

        this.setState({
            pos: {
                x: e.pageX - this.state.rel.x,
                y: e.pageY - this.state.rel.y
            }
        });
        e.stopPropagation();
        e.preventDefault();
    }


    render() {
        return (
            <span ref={this.myRef} onMouseDown={this.onMouseDown} style={{ position: 'absolute', left: this.state.pos.x + 'px', top: this.state.pos.y + 'px' }}>
                {this.props.children}

        )
    }
}

export default Draggable;

From Effective Go:

To delete a map entry, use the delete built-in function, whose arguments are the map and the key to be deleted. It's safe to do this even if the key is already absent from the map.

delete(timeZone, "PDT")  // Now on Standard Time

I had this problem. I solved it with downloading 64x of the Java. Here is the link: http://javadl.sun.com/webapps/download/AutoDL?BundleId=87443

I would recommend using DialogFragment.

Sure, creating a "Yes/No" dialog with it is pretty complex considering that it should be rather simple task, but creating a similar dialog box with Dialog is surprisingly complicated as well.

(Activity lifecycle makes it complicated - you must let Activity manage the lifecycle of the dialog box - and there is no way to pass custom parameters e.g. the custom message to Activity.showDialog if using API levels under 8)

The nice thing is that you can usually build your own abstraction on top of DialogFragment pretty easily.

Expanding a bit on Ivan's first answer a bit, you can use a string as the collection without a track by statement so long as the characters are unique, so if the use-case is less than 10 numbers as is the question I would simply do:

<ul>
   <li ng-repeat="n in '12345'"><span>{{n}}</span></li>
</ul>

Which is a bit jenky, sure, but simple enough to look at and not particularly confusing.

If your class is non-activity class, and creating an instance of it from the activiy, you can pass an instance of context via constructor of the later as follows:

class YourNonActivityClass{

// variable to hold context
private Context context;

//save the context recievied via constructor in a local variable

public YourNonActivityClass(Context context){
    this.context=context;
}

}

You can create instance of this class from the activity as follows:

new YourNonActivityClass(this);

That site makes use of the "fragment" part of a url: the stuff after the "#". This is not sent to the server by the browser as part of the GET request, but can be used to store page state. So yes you can change the fragment without causing a page refresh or reload. When the page loads, your javascript reads this fragment and updates the page content appropriately, fetching data from the server via ajax requests as required. To read the fragment in js:

var fragment = location.hash;

but note that this value will include the "#" character at the beginning. To set the fragment:

location.hash = "your_state_data";

I am using a .Net Core 2.1 Web Application and could not get a single answer here to work. I either got a blank parameter (if the method was called at all) or a 500 server error. I started playing with every possible combination of answers and finally got a working result.

In my case the solution was as follows:

Script - stringify the original array (without using a named property)

    $.ajax({
        type: 'POST',
        contentType: 'application/json; charset=utf-8',
        url: mycontrolleraction,
        data: JSON.stringify(things)
    });

And in the controller method, use [FromBody]

    [HttpPost]
    public IActionResult NewBranch([FromBody]IEnumerable<Thing> things)
    {
        return Ok();
    }

Failures include:

• Naming the content

  data: { content: nodes }, // Server error 500

• Not having the contentType = Server error 500

Notes

• dataType is not needed, despite what some answers say, as that is used for the response decoding (so not relevant to the request examples here).
• List<Thing> also works in the controller method

I think this need to be run from the Management Shell rather than the console, it sounds like the module isn't being imported into the Powershell console. You can add the module by running:

Add-PSSnapin Microsoft.Sharepoint.Powershell

in the Powershell console.

'Killing a thread' is not the right phrase to use. Here is one way we can implement graceful completion/exit of the thread on will:

Runnable which I used:

class TaskThread implements Runnable {

    boolean shouldStop;

    public TaskThread(boolean shouldStop) {
        this.shouldStop = shouldStop;
    }

    @Override
    public void run() {

        System.out.println("Thread has started");

        while (!shouldStop) {
            // do something
        }

        System.out.println("Thread has ended");

    }

    public void stop() {
        shouldStop = true;
    }

}

The triggering class:

public class ThreadStop {

    public static void main(String[] args) {

        System.out.println("Start");

        // Start the thread
        TaskThread task = new TaskThread(false);
        Thread t = new Thread(task);
        t.start();

        // Stop the thread
        task.stop();

        System.out.println("End");

    }

}

Somewhat easy to make add or remove HTML5 validation to fieldsets.

 $('form').each(function(){

    // CLEAR OUT ALL THE HTML5 REQUIRED ATTRS
    $(this).find('.required').attr('required', false);

    // ADD THEM BACK TO THE CURRENT FIELDSET
    // I'M JUST USING A CLASS TO IDENTIFY REQUIRED FIELDS
    $(this).find('fieldset.current .required').attr('required', true);

    $(this).submit(function(){

        var current     = $(this).find('fieldset.current')
        var next        = $(current).next()

        // MOVE THE CURRENT MARKER
        $(current).removeClass('current');
        $(next).addClass('current');

        // ADD THE REQUIRED TAGS TO THE NEXT PART
        // NO NEED TO REMOVE THE OLD ONES
        // SINCE THEY SHOULD BE FILLED OUT CORRECTLY
        $(next).find('.required').attr('required', true);

    });

});

you can use use numpy.random module, you can get array of random number in shape of your choice you want

>>> import numpy as np
>>> np.random.random(1)[0]
0.17425892129128229
>>> np.random.random((3,2))
array([[ 0.7978787 ,  0.9784473 ],
       [ 0.49214277,  0.06749958],
       [ 0.12944254,  0.80929816]])
>>> np.random.random((3,1))
array([[ 0.86725993],
       [ 0.36869585],
       [ 0.2601249 ]])
>>> np.random.random((4,1))
array([[ 0.87161403],
       [ 0.41976921],
       [ 0.35714702],
       [ 0.31166808]])
>>> np.random.random_sample()
0.47108547995356098

The error code 10060 means it cannot connect to the remote peer. It might be because of the network problem or mostly your setting issues, such as proxy setting.

You could try to connect the same host with other tools(such as ncat) and/or with another PC within your same local network to find out where the problem is occuring.

For proxy issue, there are some material here:

Why can't I get Python's urlopen() method to work on Windows?

Hope it helps!

Vanilla JavaScript

Using plain old JavaScript:

var val = "Fish";_x000D_
var sel = document.getElementById('sel');_x000D_
document.getElementById('btn').onclick = function() {_x000D_
  var opts = sel.options;_x000D_
  for (var opt, j = 0; opt = opts[j]; j++) {_x000D_
    if (opt.value == val) {_x000D_
      sel.selectedIndex = j;_x000D_
      break;_x000D_
    }_x000D_
  }_x000D_
}

<select id="sel">_x000D_
    <option>Cat</option>_x000D_
    <option>Dog</option>_x000D_
    <option>Fish</option>_x000D_
</select>_x000D_
<button id="btn">Select Fish</button>

jQuery

But if you really want to use jQuery:

var val = 'Fish';
$('#btn').on('click', function() {
  $('#sel').val(val);
});

var val = 'Fish';_x000D_
$('#btn').on('click', function() {_x000D_
  $('#sel').val(val);_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>_x000D_
<select id="sel">_x000D_
    <option>Cat</option>_x000D_
    <option>Dog</option>_x000D_
    <option>Fish</option>_x000D_
</select>_x000D_
<button id="btn">Select Fish</button>

jQuery - Using Value Attributes

In case your options have value attributes which differ from their text content and you want to select via text content:

<select id="sel">
    <option value="1">Cat</option>
    <option value="2">Dog</option>
    <option value="3">Fish</option>
</select>
<script>
    var val = 'Fish';
    $('#sel option:contains(' + val + ')').prop({selected: true});
</script>

Demo

But if you do have the above set up and want to select by value using jQuery, you can do as before:

var val = 3;
$('#sel').val(val);

Modern DOM

For the browsers that support document.querySelector and the HTMLOptionElement::selected property, this is a more succinct way of accomplishing this task:

var val = 3;    
document.querySelector('#sel [value="' + val + '"]').selected = true;

Demo

Knockout.js

<select data-bind="value: val">
    <option value="1">Cat</option>
    <option value="2">Dog</option>
    <option value="3">Fish</option>
</select>
<script>
    var viewModel = {
        val: ko.observable()
    };
    ko.applyBindings(viewModel);
    viewModel.val(3);
</script>

Demo

Polymer

<template id="template" is="dom-bind">
    <select value="{{ val }}">
        <option value="1">Cat</option>
        <option value="2">Dog</option>
        <option value="3">Fish</option>
    </select>
</template>
<script>
    template.val = 3;
</script>

Demo

Angular 2

Note: this has not been updated for the final stable release.

<app id="app">
    <select [value]="val">
        <option value="1">Cat</option>
        <option value="2">Dog</option>
        <option value="3">Fish</option>
    </select>
</app>
<script>
    var App = ng.Component({selector: 'app'})
        .View({template: app.innerHTML})
        .Class({constructor:  function() {}});

    ng.bootstrap(App).then(function(app) {
        app._hostComponent.instance.val = 3;
    });
</script>

Demo

Vue 2

<div id="app">
    <select v-model="val">
        <option value="1">Cat</option>
        <option value="2">Dog</option>
        <option value="3">Fish</option>
    </select>
</div>
<script>
    var app = new Vue({
        el: '#app',
        data: {
                val: null,
        },
        mounted: function() {
                this.val = 3;
        }
    });
</script>

Demo

When an error occurs, the execution will continue on the next line without interrupting the script.

I had the same problem. I fixed it using the command below:

git checkout main
git fetch
git checkout branch_name
git fetch
git checkout main
git fetch
git merge branch_name

I was told to do document.close after document.write, I dont see how or why but this caused my script to wait until I closed the print dialog before it ran my window.close.

var printContent = document.getElementbyId('wrapper').innerHTML;
var disp_setting="toolbar=no,location=no,directories=no,menubar=no, scrollbars=no,width=600, height=825, left=100, top=25"
var printWindow = window.open("","",disp_setting);
printWindow.document.write(printContent);
printWindow.document.close();
printWindow.focus();
printWindow.print();

printWindow.close();

Your best bet is probably to use pygame/SDL. It's an external library, but it has great support across platforms.

pygame.mixer.init()
pygame.mixer.music.load("file.mp3")
pygame.mixer.music.play()

You can find more specific documentation about the audio mixer support in the pygame.mixer.music documentation

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

Java isn't able to delete folders with data in it. You have to delete all files before deleting the folder.

Use something like:

String[]entries = index.list();
for(String s: entries){
    File currentFile = new File(index.getPath(),s);
    currentFile.delete();
}

Then you should be able to delete the folder by using index.delete() Untested!

There does not seem to be a way to set up a GitLab account within SourceTree, but if you just clone a remote repo it will use your SSH key correctly.

Edit: After SourceTree 3.0 it is possible to add various non-Atlassian git accounts, including GitLab.

SparkSQl support writing programs using Dataset and Dataframe API, along with it need to support sql.

In order to support Sql on DataFrames, first it requires a table definition with column names are required, along with if it creates tables the hive metastore will get lot unnecessary tables, because Spark-Sql natively resides on hive. So it will create a temporary view, which temporarily available in hive for time being and used as any other hive table, once the Spark Context stop it will be removed.

In order to create the view, developer need an utility called createOrReplaceTempView

Code:

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

list.add("a");

JSONArray array = new JSONArray();

for (int i = 0; i < list.size(); i++) {
    array.put(list.get(i));
}
JSONObject obj = new JSONObject();

try {
    obj.put("result", array);
} catch (JSONException e) {
    e.printStackTrace();
}

Here is the solution that worked for me; I did it this way as the content in the carousel was dynamically generated from user-submitted content (so we could not use a static height in the stylesheet) - This solution should also work with different sized screens:

function updateCarouselSizes(){
  jQuery(".carousel").each(function(){
    // I wanted an absolute minimum of 10 pixels
    var maxheight=10; 
    if(jQuery(this).find('.item,.carousel-item').length) {
      // We've found one or more item within the Carousel...
      jQuery(this).carousel(); // Initialise the carousel (include options as appropriate)
      // Now we iterate through each item within the carousel...
      jQuery(this).find('.item,.carousel-item').each(function(k,v){ 
        if(jQuery(this).outerHeight()>maxheight) {
          // This item is the tallest we've found so far, so store the result...
          maxheight=jQuery(this).outerHeight();
        }
      });
      // Finally we set the carousel's min-height to the value we've found to be the tallest...
      jQuery(this).css("min-height",maxheight+"px");
    }
  });
}

jQuery(function(){
  jQuery(window).on("resize",updateCarouselSizes);
  updateCarouselSizes();
}

Technically this is not responsive, but for my purposes the on window resize makes this behave responsively.

Java Strings aren't character Iterable. You'll need:

for (int i = 0; i < examplestring.length(); i++) {
  char c = examplestring.charAt(i);
  ...
}

Awkward I know.

You need to specify the attribute width to resolve in order to preserve element width

$(document).ready(function() { 
    $("#myselect").select2({ width: 'resolve' });           
});

I´ve solved with this millenary technique (you can leave the Thread.Sleep on his own in the catch)

bool deleted = false;
        do
        {
            try
            {
                Directory.Delete(rutaFinal, true);                    
                deleted = true;
            }
            catch (Exception e)
            {
                string mensaje = e.Message;
                if( mensaje == "The directory is not empty.")
                Thread.Sleep(50);
            }
        } while (deleted == false);

Implement runtime permission for running your app on Android 6.0 Marshmallow (API 23) or later.

or you can manually enable the storage permission-

goto settings>apps> "your_app_name" >click on it >then click permissions> then enable the storage. Thats it.

But i suggest go the for first one which is, Implement runtime permissions in your code.

For performance issue, first data is to be written into Buffer. When buffer get full then data is written to output (File,console etc.). When buffer is partially filled and you want to send it to output(file,console) then you need to call flush() method manually in order to write partially filled buffer to output(file,console).

I think double quotes works too:

SELECT "Business Name","Other Name" FROM your_Table

But I only tested on SQL Server NOT mySQL in case someone work with MS SQL Server.

I'm not sure what format you're looking for in your difference but here's how to do it using DateTime

$datetime1 = new DateTime();
$datetime2 = new DateTime('2011-01-03 17:13:00');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%y years %m months %a days %h hours %i minutes %s seconds');
echo $elapsed;

I had similar issues. Here is the cleanest way to do it.

    const personQuery = {
       _id: 1  
    }

    const itemID = 2;

    Person.findOne(personQuery).then(item => {
       const audioIndex = item.items.map(item => item.id).indexOf(itemID);
       item.items[audioIndex].name = 'Name value';
       item.save();
    });

You can use boost like this:

std::sort(a.begin(), a.end(), 
          boost::bind(&std::pair<int, int>::second, _1) <
          boost::bind(&std::pair<int, int>::second, _2));

I don't know a standard way to do this equally short and concise, but you can grab boost::bind it's all consisting of headers.

I know why, you are using the file name "ping" and you are using the code "ping", it just keeps trying to run itself because its selected directory in where that file is, if you want it to actually ping, put this before the ping command: "cd C:\Windows\system32", the actual file that pings the server is in there!

If you're sure that this object is an Integer :

int i = (Integer) object;

Or, starting from Java 7, you can equivalently write:

int i = (int) object;

Beware, it can throw a ClassCastException if your object isn't an Integer and a NullPointerException if your object is null.

This way you assume that your Object is an Integer (the wrapped int) and you unbox it into an int.

int is a primitive so it can't be stored as an Object, the only way is to have an int considered/boxed as an Integer then stored as an Object.

If your object is a String, then you can use the Integer.valueOf() method to convert it into a simple int :

int i = Integer.valueOf((String) object);

It can throw a NumberFormatException if your object isn't really a String with an integer as content.

Resources :

• Oracle.com - Autoboxing
• Oracle.com - Primitive Data types

On the same topic :

• Java: What's the difference between autoboxing and casting?
• Autoboxing: So I can write: Integer i = 0; instead of: Integer i = new Integer(0);
• Convert Object into primitive int

There is an .orElseRun method, but it is called .orElseGet.

The main problem with your pseudocode is that .isPresent doesn't return an Optional<>. But .map returns an Optional<> which has the orElseRun method.

If you really want to do this in one statement this is possible:

public Optional<Obj> getObjectFromDB() {
    return dao.find()
        .map( obj -> { 
            obj.setAvailable(true);
            return Optional.of(obj); 
         })
        .orElseGet( () -> {
            logger.fatal("Object not available"); 
            return Optional.empty();
    });
}

But this is even clunkier than what you had before.

I'd recommend serialization,

public class Person
{
      public  string FirstName;
      public  string MI;
      public  string LastName;
}

static void Serialize()
{
      clsPerson p = new Person();
      p.FirstName = "Jeff";
      p.MI = "A";
      p.LastName = "Price";
      System.Xml.Serialization.XmlSerializer x = new System.Xml.Serialization.XmlSerializer(p.GetType());
      x.Serialize(System.Console.Out, p);
      System.Console.WriteLine();
      System.Console.WriteLine(" --- Press any key to continue --- ");
      System.Console.ReadKey();
}

You can further control serialization with attributes.
But if it is simple, you could use XmlDocument:

using System;
using System.Xml;

public class GenerateXml {
    private static void Main() {
        XmlDocument doc = new XmlDocument();
        XmlNode docNode = doc.CreateXmlDeclaration("1.0", "UTF-8", null);
        doc.AppendChild(docNode);

        XmlNode productsNode = doc.CreateElement("products");
        doc.AppendChild(productsNode);

        XmlNode productNode = doc.CreateElement("product");
        XmlAttribute productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "01";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);

        XmlNode nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("Java"));
        productNode.AppendChild(nameNode);
        XmlNode priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        // Create and add another product node.
        productNode = doc.CreateElement("product");
        productAttribute = doc.CreateAttribute("id");
        productAttribute.Value = "02";
        productNode.Attributes.Append(productAttribute);
        productsNode.AppendChild(productNode);
        nameNode = doc.CreateElement("Name");
        nameNode.AppendChild(doc.CreateTextNode("C#"));
        productNode.AppendChild(nameNode);
        priceNode = doc.CreateElement("Price");
        priceNode.AppendChild(doc.CreateTextNode("Free"));
        productNode.AppendChild(priceNode);

        doc.Save(Console.Out);
    }
}

And if it needs to be fast, use XmlWriter:

public static void WriteXML()
{
    // Create an XmlWriterSettings object with the correct options.
    System.Xml.XmlWriterSettings settings = new System.Xml.XmlWriterSettings();
    settings.Indent = true;
    settings.IndentChars = "    "; //  "\t";
    settings.OmitXmlDeclaration = false;
    settings.Encoding = System.Text.Encoding.UTF8;

    using (System.Xml.XmlWriter writer = System.Xml.XmlWriter.Create("data.xml", settings))
    {

        writer.WriteStartDocument();
        writer.WriteStartElement("books");

        for (int i = 0; i < 100; ++i)
        {
            writer.WriteStartElement("book");
            writer.WriteElementString("item", "Book "+ (i+1).ToString());
            writer.WriteEndElement();
        }

        writer.WriteEndElement();

        writer.Flush();
        writer.Close();
    } // End Using writer 

}

And btw, the fastest way to read XML is XmlReader:

public static void ReadXML()
{
    using (System.Xml.XmlReader xmlReader = System.Xml.XmlReader.Create("http://www.ecb.int/stats/eurofxref/eurofxref-daily.xml"))
    {
        while (xmlReader.Read())
        {
            if ((xmlReader.NodeType == System.Xml.XmlNodeType.Element) && (xmlReader.Name == "Cube"))
            {
                if (xmlReader.HasAttributes)
                    System.Console.WriteLine(xmlReader.GetAttribute("currency") + ": " + xmlReader.GetAttribute("rate"));
            }

        } // Whend 

    } // End Using xmlReader

    System.Console.ReadKey();
}

And the most convenient way to read XML is to just deserialize the XML into a class.
This also works for creating the serialization classes, btw.
You can generate the class from XML with Xml2CSharp:
https://xmltocsharp.azurewebsites.net/

Here's a simple javascript function that may be useful from this link.. somehow related but we're using google earth javascript plugin instead of maps

function getApproximateDistanceUnits(point1, point2) {

    var xs = 0;
    var ys = 0;

    xs = point2.getX() - point1.getX();
    xs = xs * xs;

    ys = point2.getY() - point1.getY();
    ys = ys * ys;

    return Math.sqrt(xs + ys);
}

The units tho are not in distance but in terms of a ratio relative to your coordinates. There are other computations related you can substitute for the getApproximateDistanceUnits function link here

Then I use this function to see if a latitude longitude is within the radius

function isMapPlacemarkInRadius(point1, point2, radi) {
    if (point1 && point2) {
        return getApproximateDistanceUnits(point1, point2) <= radi;
    } else {
        return 0;
    }
}

point may be defined as

 $$.getPoint = function(lati, longi) {
        var location = {
            x: 0,
            y: 0,
            getX: function() { return location.x; },
            getY: function() { return location.y; }
        };
        location.x = lati;
        location.y = longi;

        return location;
    };

then you can do your thing to see if a point is within a region with a radius say:

 //put it on the map if within the range of a specified radi assuming 100,000,000 units
        var iconpoint = Map.getPoint(pp.latitude, pp.longitude);
        var centerpoint = Map.getPoint(Settings.CenterLatitude, Settings.CenterLongitude);

        //approx ~200 units to show only half of the globe from the default center radius
        if (isMapPlacemarkInRadius(centerpoint, iconpoint, 120)) {
            addPlacemark(pp.latitude, pp.longitude, pp.name);
        }
        else {
            otherSidePlacemarks.push({
                latitude: pp.latitude,
                longitude: pp.longitude,
                name: pp.name
            });

        }

We can check files and thire Folders.

import java.io.*;
public class fileCheck
{
    public static void main(String arg[])
    {
        File f = new File("C:/AMD");
        if (f.exists() && f.isDirectory()) {
        System.out.println("Exists");
        //if the file is present then it will show the msg  
        }
        else{
        System.out.println("NOT Exists");
        //if the file is Not present then it will show the msg      
        }
    }
}

In 2018, you don't need jQuery for something simple like this. The built in scrollIntoView() method supports a "behavior" property to smoothly scroll to any element on the page. You can even update the browser URL with a hash to make it bookmarkable.

From this tutorial on scrolling HTML Bookmarks, here is a native way to add smooth scrolling to all anchor links on your page automatically:

let anchorlinks = document.querySelectorAll('a[href^="#"]')
 
for (let item of anchorlinks) { // relitere 
    item.addEventListener('click', (e)=> {
        let hashval = item.getAttribute('href')
        let target = document.querySelector(hashval)
        target.scrollIntoView({
            behavior: 'smooth',
            block: 'start'
        })
        history.pushState(null, null, hashval)
        e.preventDefault()
    })
}

If you have a table with just a stored date (no time) and want to get those by "now", then you can do this:

SELECT * FROM tbl WHERE DATEDIFF(d, yourdate, GETDATE())=0

This results in rows which day difference is 0 (so today).

For now, the best bet is probably jstz as suggested in mbayloon's answer.

For completeness, it should be mentioned that there is a standard on it's way: Intl. You can see this in Chrome already:

> Intl.DateTimeFormat().resolvedOptions().timeZone
"America/Los_Angeles"

(This doesn't actually follow the standard, which is one more reason to stick with the library)

You can create your getValue function with the following code:

bool getValue(const std::map<int, Bar>& input, int key, Bar& out)
{
   std::map<int, Bar>::iterator foundIter = input.find(key);
   if (foundIter != input.end())
   {
      out = foundIter->second;
      return true;
   }
   return false;
}

Do a separate check for an empty string ( as it is one specific case ) and set it to zero in this case.

You could appeand "0" to the start, but then you need to add a prefix to indicate that it is a decimal and not an octal number

You don't have any error in either of your queries. My guess is the following:

• No records exists between 2013-10-17' and '2013-10-18'
• the records the second query returns you exist after '2013-10-18'

Use IPython display to render PIL images in a notebook.

from PIL import Image               # to load images
from IPython.display import display # to display images

pil_im = Image.open('path/to/image.jpg')
display(pil_im)

Use the plist settings mentioned above and the appropriate accessor (AVCaptureDevice or PHPhotoLibrary), but also alert them and send them to settings if you really need this, like so:

Swift 4.0 and 4.1

func proceedWithCameraAccess(identifier: String){
    // handler in .requestAccess is needed to process user's answer to our request
    AVCaptureDevice.requestAccess(for: .video) { success in
      if success { // if request is granted (success is true)
        DispatchQueue.main.async {
          self.performSegue(withIdentifier: identifier, sender: nil)
        }
      } else { // if request is denied (success is false)
        // Create Alert
        let alert = UIAlertController(title: "Camera", message: "Camera access is absolutely necessary to use this app", preferredStyle: .alert)

        // Add "OK" Button to alert, pressing it will bring you to the settings app
        alert.addAction(UIAlertAction(title: "OK", style: .default, handler: { action in
          UIApplication.shared.open(URL(string: UIApplicationOpenSettingsURLString)!)
        }))
        // Show the alert with animation
        self.present(alert, animated: true)
      }
    }
  }

SELECT  CAST(LoginTime AS DATE)
         FROM    AuditTrail 

If you want to have some filters over this datetime or it's different parts, you can use built-in functions such as Year and Month

As an addendum: this can also occur if you update a nuget package that was used to generate a fakes assembly. Say you install V1.0 of a nuget package and create a fakes assembly "fakeLibrary.1.0.0.0.Fakes". Next, you update to the newest version of the nuget package, say v1.1 which added a new method to an interface. The Fakes library is still looking for v1.0 of the library. Simply remove the fake assembly and regenerate it. If that was the issue, this will probably fix it.

This will work for MySQL, Postgres, and probably any other PDO driver that uses the LIMIT clause.

Notice LIMIT 0 is added for improved performance:

$rs = $db->query('SELECT * FROM my_table LIMIT 0');
for ($i = 0; $i < $rs->columnCount(); $i++) {
    $col = $rs->getColumnMeta($i);
    $columns[] = $col['name'];
}
print_r($columns);

Convert the integer into a string and then you can use the STUFF function to insert in your colons into time string. Once you've done that you can convert the string into a time datatype.

SELECT CAST(STUFF(STUFF(STUFF(cast(23421155 as varchar),3,0,':'),6,0,':'),9,0,'.') AS TIME)

That should be the simplest way to convert it to a time without doing anything to crazy.

In your example you also had an int where the leading zeros are not there. In that case you can simple do something like this:

SELECT CAST(STUFF(STUFF(STUFF(RIGHT('00000000' + CAST(421151 AS VARCHAR),8),3,0,':'),6,0,':'),9,0,'.') AS TIME)

When you do $("#vinanghinguyen_images_bbocde").val('');, it removes all the content of the textarea, so if that's not what is happening, the problem is probably somewhere else.

It might help if you post a little bit larger portion of your code, since the example you provided works.

M refers to the first non-ambiguous character in "decimal". If you don't add it the number will be treated as a double.

D is double.

System.Environment.MachineName

Or, if you are using Winforms, you can use System.Windows.Forms.SystemInformation.ComputerName, which returns exactly the same value as System.Environment.MachineName.

use

 $(document).height()

  overflow=auto

Since Join-Path can be piped a path value, you can pipe multiple Join-Path statements together:

Join-Path "C:" -ChildPath "Windows" | Join-Path -ChildPath "system32" | Join-Path -ChildPath "drivers"

It's not as terse as you would probably like it to be, but it's fully PowerShell and is relatively easy to read.

System.currentTimeMillis() does give you the number of milliseconds since January 1, 1970 00:00:00 UTC. The reason you see local times might be because you convert a Date instance to a string before using it. You can use DateFormats to convert Dates to Strings in any timezone:

DateFormat df = DateFormat.getTimeInstance();
df.setTimeZone(TimeZone.getTimeZone("gmt"));
String gmtTime = df.format(new Date());

Pythonic way to get text from Span tags:

driver.find_element_by_xpath("//*[@id='customSelect_3']/.//span[contains(@class,'selectLabel clear')]").text

Based on the other answers to this question, I've implemented a new approach using bcrypt.

Why use bcrypt

If I understand correctly, the argument to use bcrypt over SHA512 is that bcrypt is designed to be slow. bcrypt also has an option to adjust how slow you want it to be when generating the hashed password for the first time:

# The '12' is the number that dictates the 'slowness'
bcrypt.hashpw(password, bcrypt.gensalt( 12 ))

Slow is desirable because if a malicious party gets their hands on the table containing hashed passwords, then it is much more difficult to brute force them.

Implementation

def get_hashed_password(plain_text_password):
    # Hash a password for the first time
    #   (Using bcrypt, the salt is saved into the hash itself)
    return bcrypt.hashpw(plain_text_password, bcrypt.gensalt())

def check_password(plain_text_password, hashed_password):
    # Check hashed password. Using bcrypt, the salt is saved into the hash itself
    return bcrypt.checkpw(plain_text_password, hashed_password)

Notes

I was able to install the library pretty easily in a linux system using:

pip install py-bcrypt

However, I had more trouble installing it on my windows systems. It appears to need a patch. See this Stack Overflow question: py-bcrypt installing on win 7 64bit python

React users, here's an answer for completeness.

React version 16.4.2

You either want to update for every keystroke, or get the value only at submit. Adding the key events to the component works, but there are alternatives as recommended in the official docs.

Controlled vs Uncontrolled components

Controlled

From the Docs - Forms and Controlled components:

In HTML, form elements such as input, textarea, and select typically maintain their own state and update it based on user input. In React, mutable state is typically kept in the state property of components, and only updated with setState().

We can combine the two by making the React state be the “single source of truth”. Then the React component that renders a form also controls what happens in that form on subsequent user input. An input form element whose value is controlled by React in this way is called a “controlled component”.

If you use a controlled component you will have to keep the state updated for every change to the value. For this to happen, you bind an event handler to the component. In the docs' examples, usually the onChange event.

Example:

1) Bind event handler in constructor (value kept in state)

constructor(props) {
    super(props);
    this.state = {value: ''};

    this.handleChange = this.handleChange.bind(this);
}

2) Create handler function

handleChange(event) {
    this.setState({value: event.target.value});
}

3) Create form submit function (value is taken from the state)

handleSubmit(event) {
    alert('A name was submitted: ' + this.state.value);
    event.preventDefault();
}

4) Render

<form onSubmit={this.handleSubmit}>
    <label>
      Name:
      <input type="text" value={this.state.value} onChange={this.handleChange} />
    </label>
    <input type="submit" value="Submit" />
</form>

If you use controlled components, your handleChange function will always be fired, in order to update and keep the proper state. The state will always have the updated value, and when the form is submitted, the value will be taken from the state. This might be a con if your form is very long, because you will have to create a function for every component, or write a simple one that handles every component's change of value.

Uncontrolled

From the Docs - Uncontrolled component

In most cases, we recommend using controlled components to implement forms. In a controlled component, form data is handled by a React component. The alternative is uncontrolled components, where form data is handled by the DOM itself.

To write an uncontrolled component, instead of writing an event handler for every state update, you can use a ref to get form values from the DOM.

The main difference here is that you don't use the onChange function, but rather the onSubmit of the form to get the values, and validate if neccessary.

Example:

1) Bind event handler and create ref to input in constructor (no value kept in state)

constructor(props) {
    super(props);
    this.handleSubmit = this.handleSubmit.bind(this);
    this.input = React.createRef();
}

2) Create form submit function (value is taken from the DOM component)

handleSubmit(event) {
    alert('A name was submitted: ' + this.input.current.value);
    event.preventDefault();
}

3) Render

<form onSubmit={this.handleSubmit}>
    <label>
      Name:
      <input type="text" ref={this.input} />
    </label>
    <input type="submit" value="Submit" />
</form>

If you use uncontrolled components, there is no need to bind a handleChange function. When the form is submitted, the value will be taken from the DOM and the neccessary validations can happen at this point. No need to create any handler functions for any of the input components as well.

Your issue

Now, for your issue:

... I want it to be called when I push 'Enter when the whole number has been entered

If you want to achieve this, use an uncontrolled component. Don't create the onChange handlers if it is not necessary. The enter key will submit the form and the handleSubmit function will be fired.

Changes you need to do:

Remove the onChange call in your element

var inputProcent = React.CreateElement(bootstrap.Input, {type: "text",
    //    bsStyle: this.validationInputFactor(),
    placeholder: this.initialFactor,
    className: "input-block-level",
    // onChange: this.handleInput,
    block: true,
    addonBefore: '%',
    ref:'input',
    hasFeedback: true
});

Handle the form submit and validate your input. You need to get the value from your element in the form submit function and then validate. Make sure you create the reference to your element in the constructor.

  handleSubmit(event) {
      // Get value of input field
      let value = this.input.current.value;
      event.preventDefault();
      // Validate 'value' and submit using your own api or something
  }

Example use of an uncontrolled component:

class NameForm extends React.Component {
  constructor(props) {
    super(props);
    // bind submit function
    this.handleSubmit = this.handleSubmit.bind(this);
    // create reference to input field
    this.input = React.createRef();
  }

  handleSubmit(event) {
    // Get value of input field
    let value = this.input.current.value;
    console.log('value in input field: ' + value );
    event.preventDefault();
    // Validate 'value' and submit using your own api or something
  }

  render() {
    return (
      <form onSubmit={this.handleSubmit}>
        <label>
          Name:
          <input type="text" ref={this.input} />
        </label>
        <input type="submit" value="Submit" />
      </form>
    );
  }
}

ReactDOM.render(
  <NameForm />,
  document.getElementById('root')
);

Always use library. Never use require.

In a nutshell, this is because, when using require, your code might yield different, erroneous results, without signalling an error. This is rare but not hypothetical! Consider this code, which yields different results depending on whether {dplyr} can be loaded:

require(dplyr)

x = data.frame(y = seq(100))
y = 1
filter(x, y == 1)

This can lead to subtly wrong results. Using library instead of require throws an error here, signalling clearly that something is wrong. This is good.

It also makes debugging all other failures more difficult: If you require a package at the start of your script and use its exports in line 500, you’ll get an error message “object ‘foo’ not found” in line 500, rather than an error “there is no package called ‘bla’”.

The only acceptable use case of require is when its return value is immediately checked, as some of the other answers show. This is a fairly common pattern but even in these cases it is better (and recommended, see below) to instead separate the existence check and the loading of the package. That is: use requireNamespace instead of require in these cases.

More technically, require actually calls library internally (if the package wasn’t already attached — require thus performs a redundant check, because library also checks whether the package was already loaded). Here’s a simplified implementation of require to illustrate what it does:

require = function (package) {
    already_attached = paste('package:', package) %in% search()
    if (already_attached) return(TRUE)
    maybe_error = try(library(package, character.only = TRUE)) 
    success = ! inherits(maybe_error, 'try-error')
    if (! success) cat("Failed")
    success
}

Experienced R developers agree:

Yihui Xie, author of {knitr}, {bookdown} and many other packages says:

Ladies and gentlemen, I've said this before: require() is the wrong way to load an R package; use library() instead

Hadley Wickham, author of more popular R packages than anybody else, says

Use library(x) in data analysis scripts. […] You never need to use require() (requireNamespace() is almost always better)

When installing a tool globally it's to be used by a user as a command line utility anywhere, including outside of node projects. Global installs for a node project are bad because they make deployment more difficult.

npm 5.2+

The npx utility bundled with npm 5.2 solves this problem. With it you can invoke locally installed utilities like globally installed utilities (but you must begin the command with npx). For example, if you want to invoke a locally installed eslint, you can do:

npx eslint .

npm < 5.2

When used in a script field of your package.json, npm searches node_modules for the tool as well as globally installed modules, so the local install is sufficient.

So, if you are happy with (in your package.json):

"devDependencies": {
    "gulp": "3.5.2"
}
"scripts": {
    "test": "gulp test"
}

etc. and running with npm run test then you shouldn't need the global install at all.

Both methods are useful for getting people set up with your project since sudo isn't needed. It also means that gulp will be updated when the version is bumped in the package.json, so everyone will be using the same version of gulp when developing with your project.

Addendum:

It appears that gulp has some unusual behaviour when used globally. When used as a global install, gulp looks for a locally installed gulp to pass control to. Therefore a gulp global install requires a gulp local install to work. The answer above still stands though. Local installs are always preferable to global installs.

It works the same way for axes: parse(text='70^o*N') will raise the o as a superscript (the *N is to make sure the N doesn't get raised too).

labelsX=parse(text=paste(abs(seq(-100, -50, 10)), "^o ", "*W", sep=""))
labelsY=parse(text=paste(seq(50,100,10), "^o ", "*N", sep=""))
plot(-100:-50, 50:100, type="n", xlab="", ylab="", axes=FALSE)
axis(1, seq(-100, -50, 10), labels=labelsX)
axis(2, seq(50, 100, 10), labels=labelsY)
box()

Extending the int class and overriding __lt__ is one of the ways.

import queue
class MyInt(int):
    def __lt__(self, other):
        return self > other

def main():
    q = queue.PriorityQueue()
    q.put(MyInt(10))
    q.put(MyInt(5))
    q.put(MyInt(1))
    while not q.empty():
        print (q.get())


if __name__ == "__main__":
    main()

Is there a way to increase this size of memory an application can use?

Applications running on API Level 11+ can have android:largeHeap="true" on the <application> element in the manifest to request a larger-than-normal heap size, and getLargeMemoryClass() on ActivityManager will tell you how big that heap is. However:

1. This only works on API Level 11+ (i.e., Honeycomb and beyond)

2. There is no guarantee how large the large heap will be

3. The user will perceive your large-heap request, because it will force their other apps out of RAM terminate other apps' processes to free up system RAM for use by your large heap

4. Because of #3, and the fact that I expect that android:largeHeap will be abused, support for this may be abandoned in the future, or the user may be warned about this at install time (e.g., you will need to request a special permission for it)

5. Presently, this feature is lightly documented

$result=mysql_query("SELECT SUM(column) AS total_value FROM table name WHERE column='value'");
$result=mysql_result($result,0,0);

You can delete any QuerySet you'd like. For example, to delete all blog posts with some Post model

Post.objects.all().delete()

and to delete any Post with a future publication date

Post.objects.filter(pub_date__gt=datetime.now()).delete()

You do, however, need to come up with a way to narrow down your QuerySet. If you just want a view to delete a particular object, look into the delete generic view.

EDIT:

Sorry for the misunderstanding. I think the answer is somewhere between. To implement your own, combine ModelForms and generic views. Otherwise, look into 3rd party apps that provide similar functionality. In a related question, the recommendation was django-filter.

This is due to the series df[cat] containing elements that have varying data types e.g.(strings and/or floats). This could be due to the way the data is read, i.e. numbers are read as float and text as strings or the datatype was float and changed after the fillna operation.

In other words

pandas data type 'Object' indicates mixed types rather than str type

so using the following line:

df[cat] = le.fit_transform(df[cat].astype(str))

should help

According to this page it is not supported:

• 2007-12-03 : Multi-row INSERT a.k.a. compound INSERT not supported.

  INSERT INTO table (col1, col2) VALUES 
      ('row1col1', 'row1col2'), ('row2col1', 'row2col2'), ...

Actually, according to the SQL92 standard, a VALUES expression should be able to stand on itself. For example, the following should return a one-column table with three rows: VALUES 'john', 'mary', 'paul';

As of version 3.7.11 SQLite does support multi-row-insert. Richard Hipp comments:

"The new multi-valued insert is merely syntactic suger (sic) for the compound insert. There is no performance advantage one way or the other."

I created an example spreadsheet here of how to do this with simple Excel formulae, and without use of macros (you will need to make your own adjustments for getting rid of the first row, but this should be easy once you figure out how my example spreadsheet works):

Editor issue. When you create new files that not using Angular CLI, make sure you go to File > Save All (VS Code) to let the Editor aware of your new changes. Then run "ng serve --open" again. It solved mine. Hope it helps

Do you really want to simply push your local repository (with its local branches, etc.) to the new remote or do you really want to mirror the old remote (with all its branches, tags, etc) on the new remote? If the latter here's a great blog on How to properly mirror a git repository.

I strongly encourage you to read the blog for some very important details, but the short version is this:

In a new directory run these commands:

git clone --mirror [email protected]/upstream-repository.git
cd upstream-repository.git
git push --mirror [email protected]/new-location.git

You probably have something like:

"typescript":"~2.1.6"

in your package.json which npm updates to the latest minor version, in your case being 2.4.1

Edit: Question from OP

But that doesn't explain why "npm install" would change the lock file. Isn't the lock file meant to create a reproducible build? If so, regardless of the semver value, it should still use the same 2.1.6 version.

Answer:

This is intended to lock down your full dependency tree. Let's say typescript v2.4.1 requires widget ~v1.0.0. When you npm install it grabs widget v1.0.0. Later on your fellow developer (or CI build) does an npm install and gets typescript v2.4.1 but widget has been updated to widget v1.0.1. Now your node module are out of sync. This is what package-lock.json prevents.

Or more generally:

As an example, consider

package A:

{ "name": "A", "version": "0.1.0", "dependencies": { "B": "<0.1.0" } }

package B:

{ "name": "B", "version": "0.0.1", "dependencies": { "C": "<0.1.0" } }

and package C:

{ "name": "C", "version": "0.0.1" }

If these are the only versions of A, B, and C available in the registry, then a normal npm install A will install:

[email protected] -- [email protected] -- [email protected]

However, if [email protected] is published, then a fresh npm install A will install:

[email protected] -- [email protected] -- [email protected] assuming the new version did not modify B's dependencies. Of course, the new version of B could include a new version of C and any number of new dependencies. If such changes are undesirable, the author of A could specify a dependency on [email protected]. However, if A's author and B's author are not the same person, there's no way for A's author to say that he or she does not want to pull in newly published versions of C when B hasn't changed at all.

OP Question 2: So let me see if I understand correctly. What you're saying is that the lock file specifies the versions of the secondary dependencies, but still relies on the fuzzy matching of package.json to determine the top-level dependencies. Is that accurate?

Answer: No. package-lock locks the entire package tree, including the root packages described in package.json. If typescript is locked at 2.4.1 in your package-lock.json, it should remain that way until it is changed. And lets say tomorrow typescript releases version 2.4.2. If I checkout your branch and run npm install, npm will respect the lockfile and install 2.4.1.

More on package-lock.json:

package-lock.json is automatically generated for any operations where npm modifies either the node_modules tree, or package.json. It describes the exact tree that was generated, such that subsequent installs are able to generate identical trees, regardless of intermediate dependency updates.

This file is intended to be committed into source repositories, and serves various purposes:

Describe a single representation of a dependency tree such that teammates, deployments, and continuous integration are guaranteed to install exactly the same dependencies.

Provide a facility for users to "time-travel" to previous states of node_modules without having to commit the directory itself.

To facilitate greater visibility of tree changes through readable source control diffs.

And optimize the installation process by allowing npm to skip repeated metadata resolutions for previously-installed packages.

Yes. Importing CSS file into another CSS file is possible.

It must be the first rule in the style sheet using the @import rule.

@import "mystyle.css";
@import url("mystyle.css");

The only caveat is that older web browsers will not support it. In fact, this is one of the CSS 'hack' to hide CSS styles from older browsers.

Refer to this list for browser support.

I understand the need for packages in certain situations, but the base language is so elegant and so proven (and debugged and optimized).

Why not:

dt <- as.Date("2014-03-16")
dt2 <- as.POSIXlt(dt)
dt2$yday
[1] 74

And then your choice whether the first week of the year is zero (as in indexing in C) or 1 (as in indexing in R).

No packages to learn, update, worry about bugs in.

First of all, do you really need to store indices like this? Have you looked into std::map, enabling you to store key => value pairs?

Secondly, if you used iterators instead, you would be able to return std::vector.end() to indicate an invalid result. To convert an iterator to an index you simply use

size_t i = it - myvector.begin();

From my little date difference calculator:

var startDate = new Date(2000, 1-1, 1);  // 2000-01-01
var endDate =   new Date();              // Today

// Calculate the difference of two dates in total days
function diffDays(d1, d2)
{
  var ndays;
  var tv1 = d1.valueOf();  // msec since 1970
  var tv2 = d2.valueOf();

  ndays = (tv2 - tv1) / 1000 / 86400;
  ndays = Math.round(ndays - 0.5);
  return ndays;
}

So you would call:

var nDays = diffDays(startDate, endDate);

(Full source at http://david.tribble.com/src/javascript/jstimespan.html.)

Addendum

The code can be improved by changing these lines:

  var tv1 = d1.getTime();  // msec since 1970
  var tv2 = d2.getTime();

This behaviour is implementation specific. To guarantee the correctness of the iterator you should use "it = numbers.erase(it);" statement if you need to delete the element and simply incerement iterator in other case.

A good idea is to set all of the "" (blank cells) to NA before any further analysis.

If you are reading your input from a file, it is a good choice to cast all "" to NAs:

foo <- read.table(file="Your_file.txt", na.strings=c("", "NA"), sep="\t") # if your file is tab delimited

If you have already your table loaded, you can act as follows:

foo[foo==""] <- NA

Then to keep only rows with no NA you may just use na.omit():

foo <- na.omit(foo)

Or to keep columns with no NA:

foo <- foo[, colSums(is.na(foo)) == 0] 

There is no native event you can hook into for this however you can trigger an event from your script after you have made the div visible using the .trigger function

e.g

//declare event to run when div is visible
function isVisible(){
   //do something

}

//hookup the event
$('#someDivId').bind('isVisible', isVisible);

//show div and trigger custom event in callback when div is visible
$('#someDivId').show('slow', function(){
    $(this).trigger('isVisible');
});

instead of

x <- x[! x %in% c(2,3,5)]

using the packages purrr and magrittr, you can do:

your_vector %<>% discard(~ .x %in% c(2,3,5))

this allows for subsetting using the vector name only once. And you can use it in pipes :)

Finaly I found another answer for this problem. and this is working for me. Just add below datas to the your webconfig file.

<configuration>
 <system.webServer>
  <security>
   <requestFiltering>
    <verbs allowUnlisted="true">
     <add verb="OPTIONS" allowed="false" />
    </verbs>
   </requestFiltering>
  </security>
 </system.webServer>
</configuration>

Form more information, you can visit this web site: http://www.iis.net/learn/manage/configuring-security/use-request-filtering

if you want to test your web site, is it working or not... You can use "HttpRequester" mozilla firefox plugin. for this plugin: https://addons.mozilla.org/En-us/firefox/addon/httprequester/

If you don't mind installing an additional light library, you can do this:

pip install plazy

Usage:

import plazy

txt_filter = lambda x : True if x.endswith('.txt') else False
files = plazy.list_files(root='data', filter_func=txt_filter, is_include_root=True)

The result should look something like this:

['data/a.txt', 'data/b.txt', 'data/sub_dir/c.txt']

It works on both Python 2.7 and Python 3.

in my project there is one requirement that we have make dynamic screen like Alignment of Dashboard while loading, it should display on an entire page and should get adjust dynamically, if user is maximizing or resizing the browser’s window. For this I have created url and used iframe to open one of the dynamic report which is written in cognos BI.In jsp we have to embed BI report. I have used iframe to embed this report in jsp. following code is working in my case.

<iframe src= ${cognosUrl} onload="this.style.height=(this.contentDocument.body.scrollHeight+30) +'px';" scrolling="no" style="width: 100%; min-height: 900px; border: none; overflow: hidden; height: 30px;"></iframe>

just use simple css

.big-checkbox {width: 1.5rem; height: 1.5rem;top:0.5rem}

I am using Eclipse 3.7 Indigo and Windows 7 64-bit:

What I did was to install the Microsoft Visual C++ 2008 SP1 Redistributable Package as suggested by the site and reminded by @Universalspezialist.

Then install the plugin as stated in the site: http://java.decompiler.free.fr/?q=jdeclipse

Go to preference, then find "File Associations" Click on the *.class, then set the "class File Editor" as default.

Restart Eclipse perhaps? (I did this, but I'm not sure if it's necessary or not)

Add the 'interact' Expect command just before your EOD:

#!/bin/bash

read -s PWD

/usr/bin/expect <<EOD
spawn ssh -oStrictHostKeyChecking=no -oCheckHostIP=no usr@$myhost.example.com
expect "password"
send "$PWD\n"
interact
EOD
echo "you're out"

This should let you interact with the remote machine until you log out. Then you'll be back in Bash.

DateTime.Now will not work, use DateTime.Today instead.

The factory pattern is more flexible as it can return functions and values as well as objects.

There isn't a lot of point in the service pattern IMHO, as everything it does you can just as easily do with a factory. The exceptions might be:

• If you care about the declared type of your instantiated service for some reason - if you use the service pattern, your constructor will be the type of the new service.
• If you already have a constructor function that you're using elsewhere that you also want to use as a service (although probably not much use if you want to inject anything into it!).

Arguably, the service pattern is a slightly nicer way to create a new object from a syntax point of view, but it's also more costly to instantiate. Others have indicated that angular uses "new" to create the service, but this isn't quite true - it isn't able to do that because every service constructor has a different number of parameters. What angular actually does is use the factory pattern internally to wrap your constructor function. Then it does some clever jiggery pokery to simulate javascript's "new" operator, invoking your constructor with a variable number of injectable arguments - but you can leave out this step if you just use the factory pattern directly, thus very slightly increasing the efficiency of your code.

You can change it by going File => Settings (Shortcut CTRL+ ALT+ S) , from Left panel Choose Appearance , Now from Right Panel choose theme.

Android Studio 2.1

Preference -> Search for Appearance -> UI options , Click on DropDown Theme

Android 2.2

Android studio -> File -> Settings -> Appearance & Behavior -> Look for UI Options

EDIT :

Import External Themes

You can download custom theme from this website. Choose your theme, download it. To set theme Go to Android studio -> File -> Import Settings -> Choose the .jar file downloaded.

In design patterns there is a principle called "favouring composition over inheritance". It says instead of inheriting Class B from Class A ,put an instance of class A inside class B as a property and then you can use functionalities of class A inside class B. You can see some examples of that here and here.

Try replacing apt-get with yum as Amazon Linux based AMI uses the yum command instead of apt-get.

this is the solution to close menu when click on anchor then apply this line in list item

     data-target="#sidenav-collapse-main" data-toggle="collapse"

the real example that work for me is below

      <li class="nav-item" data-target="#sidenav-collapse-main" data- 
      toggle="collapse" >
      <a class="nav-link" routerLinkActive="active" routerLink="/admin/users">

On the same layout where is defined the RecyclerView, add the TextView:

<android.support.v7.widget.RecyclerView
    android:id="@+id/recycler_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:scrollbars="vertical" />

<TextView
    android:id="@+id/empty_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:gravity="center"
    android:visibility="gone"
    android:text="@string/no_data_available" />

At the onCreate or the appropriate callback you check if the dataset that feeds your RecyclerView is empty. If the dataset is empty, the RecyclerView is empty too. In that case, the message appears on the screen. If not, change its visibility:

private RecyclerView recyclerView;
private TextView emptyView;

// ...

recyclerView = (RecyclerView) rootView.findViewById(R.id.recycler_view);
emptyView = (TextView) rootView.findViewById(R.id.empty_view);

// ...

if (dataset.isEmpty()) {
    recyclerView.setVisibility(View.GONE);
    emptyView.setVisibility(View.VISIBLE);
}
else {
    recyclerView.setVisibility(View.VISIBLE);
    emptyView.setVisibility(View.GONE);
}

Try add a extend pseudo function:

$.expr[':'].textEquals = $.expr.createPseudo(function(arg) {
    return function( elem ) {
        return $(elem).text().match("^" + arg + "$");
    };
});

Then you can do:

$('p:textEquals("Hello World")');

In my situation, the controller method was not made as async and the method called inside the controller method was async.

So I guess its important to use async/await all the way to top level to avoid issues like these.

There are lot of GUI designers even like Eclipse plugins, just few of them could use both, Swing and SWT..

WindowBuilder Pro GUI Designer - eclipse marketplace

WindowBuilder Pro GUI Designer - Google code home page

and

Jigloo SWT/Swing GUI Builder - eclipse market place

Jigloo SWT/Swing GUI Builder - home page

The window builder is quite better tool..

But IMHO, GUIs created by those tools have really ugly and unmanageable code..

Try next, but it's not useful for huge data...

SELECT DISTINCT Cat FROM (
  SELECT Category as Cat FROM MonitoringJob ORDER BY CreationDate DESC

You can enable the Android SDK installer to run on Windows x64 with JDK x64 installed, by exporting HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Development Kit registry key, adding Wow6432Node to all registry keys in the exported file and reimporting it back (should show in regedit as HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\JavaSoft\Java Development Kit as well).

Note I have both x64 and x86 JRE installed. If you have only x64 JRE, you might have to export the whole HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft registry key and reimport it under Wow6432Node. Although, I believe that the Android SDK installer just checks the JDK registry key.

A rect can't contain a text element. Instead transform a g element with the location of text and rectangle, then append both the rectangle and the text to it:

var bar = chart.selectAll("g")
    .data(data)
  .enter().append("g")
    .attr("transform", function(d, i) { return "translate(0," + i * barHeight + ")"; });

bar.append("rect")
    .attr("width", x)
    .attr("height", barHeight - 1);

bar.append("text")
    .attr("x", function(d) { return x(d) - 3; })
    .attr("y", barHeight / 2)
    .attr("dy", ".35em")
    .text(function(d) { return d; });

Multi-line labels are also a little tricky, you might want to check out this wrap function.

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.

You can also connect to a database with a different ROLE as follows.

\connect DBNAME ROLENAME;

or

\c DBNAME ROLENAME;

As stated. Gradients aren't currently supported with CSS Transitions. But you could work around it in some cases by setting one of the colors to transparent, so that the background-color of some other wrapping element shines through, and transition that instead.

From Java 8 onward you can try the following:

import java.time.*;
import java.time.temporal.ChronoUnit;

Instant start_time = Instant.now();
// Your code
Instant stop_time = Instant.now();

System.out.println(Duration.between(start_time, stop_time).toMillis());

//or

System.out.println(ChronoUnit.MILLIS.between(start_time, stop_time));

document.getElementById('some_id').className+='  someclassname'

OR:

document.getElementById('some_id').classList.add('someclassname')

First approach helped in adding the class when second approach didn't work.
Don't forget to keep a space in front of the ' someclassname' in the first approach.

For removal you can use:

document.getElementById('some_id').classList.remove('someclassname')

$('html, body').animate({scrollTop:1200},'50');

You can do this!

Java 8 and above.

By using convertedDate.getMonth().length(convertedDate.isLeapYear()) where convertedDate is an instance of LocalDate.

String date = "1/13/2012";
LocalDate convertedDate = LocalDate.parse(date, DateTimeFormatter.ofPattern("M/d/yyyy"));
convertedDate = convertedDate.withDayOfMonth(
                                convertedDate.getMonth().length(convertedDate.isLeapYear()));

Java 7 and below.

By using getActualMaximum method of java.util.Calendar:

String date = "1/13/2012";
SimpleDateFormat dateFormat = new SimpleDateFormat("MM/dd/yyyy");
Date convertedDate = dateFormat.parse(date);
Calendar c = Calendar.getInstance();
c.setTime(convertedDate);
c.set(Calendar.DAY_OF_MONTH, c.getActualMaximum(Calendar.DAY_OF_MONTH));

Use compareTo() function that's built into the class.

Something I came upon while trying to work a spinner was to allow for flexibility within the script without the use of a ton of if statements.

Since this is a simpler solution than iterating through an array to check for a single instance of a class present it keeps the script cleaner. Any suggestions for cleaning the code further are welcome.

$('.next').click(function(){
        var imageToSlide = $('#imageSprite'); // Get id of image

        switch(true) {
            case (imageToSlide.hasClass('pos1')):
                imageToSlide.removeClass('pos1').addClass('pos2');
                break;
            case (imageToSlide.hasClass('pos2')):
                imageToSlide.removeClass('pos2').addClass('pos3');
                break;
            case (imageToSlide.hasClass('pos3')):
                imageToSlide.removeClass('pos3').addClass('pos4');
                break;
            case (imageToSlide.hasClass('pos4')):
                imageToSlide.removeClass('pos4').addClass('pos1');
        }
    }); ` 

This code explains the use of the ~tilda character, which was the most confusing thing to me. Once I understood this, it makes things much easier to understand:

@ECHO off
SET "PATH=%~dp0;%PATH%"
ECHO %PATH%
ECHO.
CALL :testargs "these are days" "when the brave endure"
GOTO :pauseit
:testargs
SET ARGS=%~1;%~2;%1;%2
ECHO %ARGS%
ECHO.
exit /B 0
:pauseit
pause

Alexander Abakumov's answer is the correct one. It solved every binding issue I had updating the underlying data and having the grid update.

Its easy to implement and modify any existing source code you have.

grdDetails.DataSource = new System.Windows.Forms.BindingSource { DataSource = OrderDetails };

Try using RUN /bin/sh instead of bash.

There are a bunch of different ways depending on how far along you are and which branch(es) you want them on.

Let's take a classic mistake:

$ git checkout master
... pause for coffee, etc ...
... return, edit a bunch of stuff, then: oops, wanted to be on develop

So now you want these changes, which you have not yet committed to master, to be on develop.

1. If you don't have a develop yet, the method is trivial:

   $ git checkout -b develop
   

   This creates a new develop branch starting from wherever you are now. Now you can commit and the new stuff is all on develop.

2. You do have a develop. See if Git will let you switch without doing anything:

   $ git checkout develop
   

   This will either succeed, or complain. If it succeeds, great! Just commit. If not (error: Your local changes to the following files would be overwritten ...), you still have lots of options.

   The easiest is probably git stash (as all the other answer-ers that beat me to clicking post said). Run git stash save or git stash push,¹ or just plain git stash which is short for save / push:

   $ git stash
   

   This commits your code (yes, it really does make some commits) using a weird non-branch-y method. The commits it makes are not "on" any branch but are now safely stored in the repository, so you can now switch branches, then "apply" the stash:

   $ git checkout develop
   Switched to branch 'develop'
   $ git stash apply
   

   If all goes well, and you like the results, you should then git stash drop the stash. This deletes the reference to the weird non-branch-y commits. (They're still in the repository, and can sometimes be retrieved in an emergency, but for most purposes, you should consider them gone at that point.)

The apply step does a merge of the stashed changes, using Git's powerful underlying merge machinery, the same kind of thing it uses when you do branch merges. This means you can get "merge conflicts" if the branch you were working on by mistake, is sufficiently different from the branch you meant to be working on. So it's a good idea to inspect the results carefully before you assume that the stash applied cleanly, even if Git itself did not detect any merge conflicts.

Many people use git stash pop, which is short-hand for git stash apply && git stash drop. That's fine as far as it goes, but it means that if the application results in a mess, and you decide you don't want to proceed down this path, you can't get the stash back easily. That's why I recommend separate apply, inspect results, drop only if/when satisfied. (This does of course introduce another point where you can take another coffee break and forget what you were doing, come back, and do the wrong thing, so it's not a perfect cure.)

¹The save in git stash save is the old verb for creating a new stash. Git version 2.13 introduced the new verb to make things more consistent with pop and to add more options to the creation command. Git version 2.16 formally deprecated the old verb (though it still works in Git 2.23, which is the latest release at the time I am editing this).

Modifications to sys.path only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH environment variable:

PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH

Note that PATH is the system path for executables, which is completely separate.

**You can write the above in ~/.bash_profile and the source it using source ~/.bash_profile

Here is how you can do it:

std::string & trim(std::string & str)
{
   return ltrim(rtrim(str));
}

And the supportive functions are implemeted as:

std::string & ltrim(std::string & str)
{
  auto it2 =  std::find_if( str.begin() , str.end() , [](char ch){ return !std::isspace<char>(ch , std::locale::classic() ) ; } );
  str.erase( str.begin() , it2);
  return str;   
}

std::string & rtrim(std::string & str)
{
  auto it1 =  std::find_if( str.rbegin() , str.rend() , [](char ch){ return !std::isspace<char>(ch , std::locale::classic() ) ; } );
  str.erase( it1.base() , str.end() );
  return str;   
}

And once you've all these in place, you can write this as well:

std::string trim_copy(std::string const & str)
{
   auto s = str;
   return ltrim(rtrim(s));
}

Try this

Actually you can do with VS Code the following:

the problem here is that by using the apostrophes you are setting the value being passed to be a string, when in fact, as @Shijo stated from the documentation, the function is expecting a label or list, but not a string! If the list contains each of the name of the columns beings passed for both the left and right dataframe, then each column-name must individually be within apostrophes. With what has been stated, we can understand why this is inccorect:

new_df = pd.merge(A_df, B_df,  how='left', left_on='[A_c1,c2]', right_on = '[B_c1,c2]')

And this is the correct way of using the function:

new_df = pd.merge(A_df, B_df,  how='left', left_on=['A_c1','c2'], right_on = ['B_c1','c2'])

Have you seen the FAQ entry What if I'm behind a proxy??

... edit your "servers" configuration file to indicate which proxy to use. The files location depends on your operating system. On Linux or Unix it is located in the directory "~/.subversion". On Windows it is in "%APPDATA%\Subversion". (Try "echo %APPDATA%", note this is a hidden directory.)

For me this involved uncommenting and setting the following lines:

#http-proxy-host=my.proxy
#http-proxy-port=80
#http-proxy-username=[username]
#http-proxy-password=[password]

On command line : nano ~/.subversion/servers

Here is simple way using Top object.

eg: If absolute element size is 60px.

.absolute-element { 
    position:absolute; 
    height:60px; 
    top: calc(50% - 60px);
}

it turns out that I got this error because my requested module is not bundled in the minification prosses due to path misspelling

so make sure that your module exists in minified js file (do search for a word within it to be sure)

The file .bashrc is read when you start an interactive shell. This is the file that you should update. E.g:

export PATH=$PATH:/opt/ActiveTcl-8.5/bin

Restart the shell for the changes to take effect or source it, i.e.:

source .bashrc

I agree with much that Manuel has said. In fact, his comments refer to this url...

http://www.w3.org/TR/html401/interact/forms.html#h-17.13.4

... which states:

The content type "application/x-www-form-urlencoded" is inefficient for sending large quantities of binary data or text containing non-ASCII characters. The content type "multipart/form-data" should be used for submitting forms that contain files, non-ASCII data, and binary data.

However, for me it would come down to tool/framework support.

• What tools and frameworks do you expect your API users to be building their apps with?
• Do they have frameworks or components they can use that favour one method over the other?

If you get a clear idea of your users, and how they'll make use of your API, then that will help you decide. If you make the upload of files hard for your API users then they'll move away, of you'll spend a lot of time on supporting them.

Secondary to this would be the tool support YOU have for writing your API and how easy it is for your to accommodate one upload mechanism over the other.

just add /FORCE as linker flag and you're all set.

for instance, if you're working on CMakeLists.txt. Then add following line:

SET(CMAKE_EXE_LINKER_FLAGS  "/FORCE")

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

All the above solutions are good, but I like @Steve's and @bejota's the best as they do not involve fancy calls and are universal.

By universal I mean that works with any type of axes including GeoAxes. For example, it you have projected axes for mapping:

projection = cartopy.crs.UTM(zone='17N')
ax = plt.axes(projection=projection)
im = ax.imshow(np.arange(200).reshape((20, 10)))

a call to

cax = divider.append_axes("right", size=width, pad=pad)

will fail with: KeyException: map_projection

Therefore, the only universal way of dealing colorbar size with all types of axes is:

ax.colorbar(im, fraction=0.046, pad=0.04)

Work with fraction from 0.035 to 0.046 to get your best size. However, the values for the fraction and paddig will need to be adjusted to get the best fit for your plot and will differ depending if the orientation of the colorbar is in vertical position or horizontal.

Putting the condition in the join seems "semantically wrong" to me, as that's not what JOINs are "for". But that's very qualitative.

Additional problem: if you decide to switch from an inner join to, say, a right join, having the condition be inside the JOIN could lead to unexpected results.

I faced the same 415 http error when sending objects, serialized into JSON, via PUT/PUSH requests to my JAX-rs services, in other words my server was not able to de-serialize the objects from JSON. In my case, the server was able to serialize successfully the same objects in JSON when sending them into its responses.

As mentioned in the other responses I have correctly set the Accept and Content-Type headers to application/json, but it doesn't suffice.

Solution

I simply forgot a default constructor with no parameters for my DTO objects. Yes this is the same reasoning behind @Entity objects, you need a constructor with no parameters for the ORM to instantiate objects and populate the fields later.

Adding the constructor with no parameters to my DTO objects solved my issue. Here follows an example that resembles my code:

Wrong

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {
    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

Right

@XmlRootElement
@XmlAccessorType(XmlAccessType.FIELD)
public class NumberDTO {

    public NumberDTO() {
    }

    public NumberDTO(Number number) {
        this.number = number;
    }

    private Number number;

    public Number getNumber() {
        return number;
    }

    public void setNumber(Number string) {
        this.number = string;
    }
}

I lost hours, I hope this'll save yours ;-)

No. There is no way you can edit the result grid. The result grid is mainly for displaying purposes of the query you executed.

This for the reason that anybody can execute complex queries. Hopefully for the next release they will include this kind of functionality.

I Hope that answer your question.

I was also struggling with this problem, and find that the best way is to use a CURSOR.

I have tried Denis solution with OUTPUT, but as he mentiond, it's impossible to output external columns in an insert statement, and the MERGE can't work when insert multiple rows by select.

So, i've used a CURSOR, for each row in the outer table, i've done a INSERT, then use the @@IDENTITY for another INSERT.

DECLARE @OuterID int

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 
SELECT  ID FROM   [external_Table]

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @OuterID

WHILE @@FETCH_STATUS = 0
BEGIN 
INSERT INTO [Table]   (data)
    SELECT data
    FROM     [external_Table] where ID = @OuterID 

    INSERT INTO [second_table] (FK,OuterID)
    VALUES(@OuterID,@@identity)

    FETCH NEXT FROM MY_CURSOR INTO @OuterID
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

In short, decoupling success callback function from the ajax function so later you can add your own handlers without modifying the original code (observer pattern).

Depending on your needs, you can use one of the window.location properties. In your question you are asking about the host, which may be retrieved using window.location.hostname (e.g. www.example.com). In your example you are showing something what is called origin, which may be retrieved using window.location.origin (e.g. http://www.example.com).

var path = window.location.origin + "/";

//result = "http://localhost:60470/"

In my case, I had the mapping b/w A and B like

A has

@OneToMany(mappedBy = "a", cascade = CascadeType.ALL)
Set<B> bs;

in the DAO layer, the method needs to be annotated with @Transactional if you haven't annotated the mapping with Fetch Type - Eager

The solution by MSquare works only if you hold a specific pixel, but that's an unreasonable expectation for an end user unless they use a mouse (which they don't, they use fingers).

So I added a bit of a threshold for the distance between the DOWN and the UP action in case there was a MOVE action inbetween.

final Handler longPressHandler = new Handler();
Runnable longPressedRunnable = new Runnable() {
    public void run() {
        Log.e(TAG, "Long press detected in long press Handler!");
        isLongPressHandlerActivated = true;
    }
};

private boolean isLongPressHandlerActivated = false;

private boolean isActionMoveEventStored = false;
private float lastActionMoveEventBeforeUpX;
private float lastActionMoveEventBeforeUpY;

@Override
public boolean dispatchTouchEvent(MotionEvent event) {
    if(event.getAction() == MotionEvent.ACTION_DOWN) {
        longPressHandler.postDelayed(longPressedRunnable, 1000);
    }
    if(event.getAction() == MotionEvent.ACTION_MOVE || event.getAction() == MotionEvent.ACTION_HOVER_MOVE) {
        if(!isActionMoveEventStored) {
            isActionMoveEventStored = true;
            lastActionMoveEventBeforeUpX = event.getX();
            lastActionMoveEventBeforeUpY = event.getY();
        } else {
            float currentX = event.getX();
            float currentY = event.getY();
            float firstX = lastActionMoveEventBeforeUpX;
            float firstY = lastActionMoveEventBeforeUpY;
            double distance = Math.sqrt(
                    (currentY - firstY) * (currentY - firstY) + ((currentX - firstX) * (currentX - firstX)));
            if(distance > 20) {
                longPressHandler.removeCallbacks(longPressedRunnable);
            }
        }
    }
    if(event.getAction() == MotionEvent.ACTION_UP) {
        isActionMoveEventStored = false;
        longPressHandler.removeCallbacks(longPressedRunnable);
        if(isLongPressHandlerActivated) {
            Log.d(TAG, "Long Press detected; halting propagation of motion event");
            isLongPressHandlerActivated = false;
            return false;
        }
    }
    return super.dispatchTouchEvent(event);
}

You can also consider to reverse your array and take the first element. That way you don't have to know about the length, but it brings no real benefits and the disadvantage that the reverse operation might take longer with big arrays:

array1.split(",").reverse()[0]

It's easy though, but also modifies the original array in question. That might or might not be a problem.

Reference: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Array/reverse

Probably you might want to use this though:

array1.split(",").pop()

Update 05.11.2020:
Modified to include static fields and methods to closer replicate "true" enum behavior.

Has anyone tried doing this with a class that contains private fields and "get" accessors? I realize private class fields are still experimental at this point but it seems to work for the purposes of creating a class with immutable fields/properties. Browser support is decent as well. The only "major" browsers that don't support it are Firefox (which I'm sure they will soon) and IE (who cares).

DISCLAIMER:
I am not a developer. I was just looking for an answer to this question and started thinking about how I sometimes create "enhanced" enums in C# by creating classes with private fields and restricted property accessors.

Sample Class

class Sizes {
    // Private Fields
    static #_SMALL = 0;
    static #_MEDIUM = 1;
    static #_LARGE = 2;

    // Accessors for "get" functions only (no "set" functions)
    static get SMALL() { return this.#_SMALL; }
    static get MEDIUM() { return this.#_MEDIUM; }
    static get LARGE() { return this.#_LARGE; }
}

You should now be able to call your enums directly.

Sizes.SMALL; // 0
Sizes.MEDIUM; // 1
Sizes.LARGE; // 2

The combination of using private fields and limited accessors means that the enum values are well protected.

Sizes.SMALL = 10 // Sizes.SMALL is still 0
Sizes._SMALL = 10 // Sizes.SMALL is still 0
Sizes.#_SMALL = 10 // Sizes.SMALL is still 0

If you have Pillow installed with scipy and it is still giving you error then check your scipy version because it has been removed from scipy since 1.3.0rc1.

rather install scipy 1.1.0 by :

pip install scipy==1.1.0

check https://github.com/scipy/scipy/issues/6212

The method imread in scipy.misc requires the forked package of PIL named Pillow. If you are having problem installing the right version of PIL try using imread in other packages:

from matplotlib.pyplot import imread
im = imread(image.png)

To read jpg images without PIL use:

import cv2 as cv
im = cv.imread(image.jpg)

You can try from scipy.misc.pilutil import imread instead of from scipy.misc import imread

Please check the GitHub page : https://github.com/amueller/mglearn/issues/2 for more details.

I recommend you to try Netbeans Profiler.It has rich set of tools for real time analysis. Tools from IbM are worth a try for offline analysis

Manually, you can use pd.DataFrame constructor, giving a numpy array (data) and a list of the names of the columns (columns). To have everything in one DataFrame, you can concatenate the features and the target into one numpy array with np.c_[...] (note the []):

import numpy as np
import pandas as pd
from sklearn.datasets import load_iris

# save load_iris() sklearn dataset to iris
# if you'd like to check dataset type use: type(load_iris())
# if you'd like to view list of attributes use: dir(load_iris())
iris = load_iris()

# np.c_ is the numpy concatenate function
# which is used to concat iris['data'] and iris['target'] arrays 
# for pandas column argument: concat iris['feature_names'] list
# and string list (in this case one string); you can make this anything you'd like..  
# the original dataset would probably call this ['Species']
data1 = pd.DataFrame(data= np.c_[iris['data'], iris['target']],
                     columns= iris['feature_names'] + ['target'])

You can use .filter() method of the Array object:

var filtered = workItems.filter(function(element) {
   // Create an array using `.split()` method
   var cats = element.category.split(' ');

   // Filter the returned array based on specified filters
   // If the length of the returned filtered array is equal to
   // length of the filters array the element should be returned  
   return cats.filter(function(cat) {
       return filtersArray.indexOf(cat) > -1;
   }).length === filtersArray.length;
});

http://jsfiddle.net/6RBnB/

Some old browsers like IE8 doesn't support .filter() method of the Array object, if you are using jQuery you can use .filter() method of jQuery object.

jQuery version:

var filtered = $(workItems).filter(function(i, element) {
   var cats = element.category.split(' ');

    return $(cats).filter(function(_, cat) {
       return $.inArray(cat, filtersArray) > -1;
    }).length === filtersArray.length;
});

JavaScript's object literal syntax, which is typically used to instantiate objects (seriously, no one uses new Object or new Array), is as follows:

var obj = {
    'key': 'value',
    'another key': 'another value',
     anUnquotedKey: 'more value!'
};

For arrays it's:

var arr = [
    'value',
    'another value',
    'even more values'
];

If you need objects within objects, that's fine too:

var obj = {
    'subObject': {
        'key': 'value'
    },
    'another object': {
         'some key': 'some value',
         'another key': 'another value',
         'an array': [ 'this', 'is', 'ok', 'as', 'well' ]
    }
}

This convenient method of being able to instantiate static data is what led to the JSON data format.

JSON is a little more picky, keys must be enclosed in double-quotes, as well as string values:

{"foo":"bar", "keyWithIntegerValue":123}

# Hide grid lines
ax.grid(False)

# Hide axes ticks
ax.set_xticks([])
ax.set_yticks([])
ax.set_zticks([])

Note, you need matplotlib>=1.2 for set_zticks() to work.

There where a lot of solutions with .addImage, I tried many of them, but nothing worked out. So I found the .html() function and after some tries the html2canvas-scale-option. This solution is no general solution, you have to adjust the scale so it will fit your pdf, but this is the only solution, which works for me.

var doc = new jspdf.jsPDF({
    orientation: 'p',
    unit: 'pt',
    format: 'a4'
});

doc.html(document.querySelector('#styledTable'), {
    callback: function (doc) {
        doc.save('file.pdf');
    },
    margin: [60, 60, 60, 60],
    x: 32,
    y: 32,
    html2canvas: {
        scale: 0.3, //this was my solution, you have to adjust to your size
        width: 1000 //for some reason width does nothing
    },
});

Try this:

var local = yourDbContext.Set<YourModel>()
                         .Local
                         .FirstOrDefault(f => f.Id == yourModel.Id);
if (local != null)
{
  yourDbContext.Entry(local).State = EntityState.Detached;
}
yourDbContext.Entry(applicationModel).State = EntityState.Modified;

"ASCII is a subset of UTF-8, so..." - so UTF-8 is a set? :)

In other words: any string build with code points from x00 to x7F has indistinguishable representations (byte sequences) in ASCII and UTF-8. Converting such string is pointless.

Use padding to fake it since vertical-align doesn't work on text inputs.

jsFiddle example

CSS

.date-input {     
    width: 145px;
    padding-top: 80px;
}?

One simple way to validate a date string is to convert to a date object and test that, e.g.

// Expect input as d/m/y_x000D_
function isValidDate(s) {_x000D_
  var bits = s.split('/');_x000D_
  var d = new Date(bits[2], bits[1] - 1, bits[0]);_x000D_
  return d && (d.getMonth() + 1) == bits[1];_x000D_
}_x000D_
_x000D_
['0/10/2017','29/2/2016','01/02'].forEach(function(s) {_x000D_
  console.log(s + ' : ' + isValidDate(s))_x000D_
})

When testing a Date this way, only the month needs to be tested since if the date is out of range, the month will change. Same if the month is out of range. Any year is valid.

You can also test the bits of the date string:

function isValidDate2(s) {_x000D_
  var bits = s.split('/');_x000D_
  var y = bits[2],_x000D_
    m = bits[1],_x000D_
    d = bits[0];_x000D_
  // Assume not leap year by default (note zero index for Jan)_x000D_
  var daysInMonth = [31, 28, 31, 30, 31, 30, 31, 31, 30, 31, 30, 31];_x000D_
_x000D_
  // If evenly divisible by 4 and not evenly divisible by 100,_x000D_
  // or is evenly divisible by 400, then a leap year_x000D_
  if ((!(y % 4) && y % 100) || !(y % 400)) {_x000D_
    daysInMonth[1] = 29;_x000D_
  }_x000D_
  return !(/\D/.test(String(d))) && d > 0 && d <= daysInMonth[--m]_x000D_
}_x000D_
_x000D_
['0/10/2017','29/2/2016','01/02'].forEach(function(s) {_x000D_
  console.log(s + ' : ' + isValidDate2(s))_x000D_
})

Try this option:

radio1.Items.FindByValue("1").Selected = true;

Intent service is child of Service

IntentService: If you want to download a bunch of images at the start of opening your app. It's a one-time process and can clean itself up once everything is downloaded.

Service: A Service which will constantly be used to communicate between your app and back-end with web API calls. Even if it is finished with its current task, you still want it to be around a few minutes later, for more communication

For me this issue happened with Visual Studio Code and I was able to fix with 2 steps:

1. Manually adding using Microsoft.EntityFrameworkCore;
2. Running dotnet build in terminal.

Your resource package should contain at least one pojo which is either annotated with @Path or have at least one method annotated with @Path or a request method designator, such as @GET, @PUT, @POST, or @DELETE. Resource methods are methods of a resource class annotated with a request method designator. This resolved my issue...

This worked better for me:

$.fn.textWidth = function(){
  var html_org = $(this).html();
  var html_calc = '<span>' + html_org + '</span>';
  $(this).html(html_calc);
  var width = $(this).find('span:first').width();
  $(this).html(html_org);
  return width;
};

This is for extra information.

Imagine this scenario

1. ActivityA launch ActivityB.

2. ActivityB launch a new ActivityAPrime by

   Intent intent = new Intent(getApplicationContext(), ActivityA.class);
   startActivity(intent);
   

3. ActivityAPrime has no relationship with ActivityA.
   In this case the Bundle in ActivityAPrime.onCreate() will be null.

If ActivityA and ActivityAPrime should be the same activity instead of different activities, ActivityB should call finish() than using startActivity().

Just as you would with a CheckBox

RadioButton rb;

rb = (RadioButton) findViewById(R.id.rb);

rb.isChecked();

I realize that this is an old thread, but I thought I'd update it with my results.

Alex, it sounds like you installed MySQL server via the meta-package 'mysql-server'. This installs the latest package by reference (in my case, mysql-server-5.5). I, like you, was not prompted for a MySQL password upon setup as I had expected. I suppose there are two answers:

Solution #1: install MySQL by it's full name:

$ sudo apt-get install mysql-server-5.5

Or

Solution #2: reconfigure the package...

$ sudo dpkg-reconfigure mysql-server-5.5

You must specific the full package name. Using the meta-package 'mysql-server' did not have the desired result for me. I hope this helps someone :)

Using dplyr::mutate:

library(dplyr)
df <- mutate(df, x = paste(n, s)) 

df 
> df
  n  s     b    x
1 2 aa  TRUE 2 aa
2 3 bb FALSE 3 bb
3 5 cc  TRUE 5 cc

In Python 3.6 the fastest way is still the WouterOvermeire one. Kikohs' proposal is slower than the other two options.

import timeit

setup = '''
import pandas as pd
import numpy as np
df = pd.DataFrame(np.random.randint(32, 120, 100000).reshape(50000,2),columns=list('AB'))
df['A'] = df['A'].apply(chr)
'''

timeit.Timer('dict(zip(df.A,df.B))', setup=setup).repeat(7,500)
timeit.Timer('pd.Series(df.A.values,index=df.B).to_dict()', setup=setup).repeat(7,500)
timeit.Timer('df.set_index("A").to_dict()["B"]', setup=setup).repeat(7,500)

Results:

1.1214002349999777 s  # WouterOvermeire
1.1922008498571748 s  # Jeff
1.7034366211428602 s  # Kikohs

Use the Pattern#quote() method for escaping ||. Try:

final String[] tokens = myString.split(Pattern.quote("||"));

This is required because | is an alternation character and hence gains a special meaning when passed to split call (basically the argument to split is a regular expression in string form).

You don't need external library:

Integer[] input = Arrays.stream(arr).boxed().toArray(Integer[]::new);
Arrays.sort(input, (a, b) -> b - a); // reverse order
return Arrays.stream(input).mapToInt(Integer::intValue).toArray();
