First thing, define a type or interface for your object, it will make things much more readable:

type Product = { productId: number; price: number; discount: number };

You used a tuple of size one instead of array, it should look like this:

let myarray: Product[];
let priceListMap : Map<number, Product[]> = new Map<number, Product[]>();

So now this works fine:

myarray.push({productId : 1 , price : 100 , discount : 10});
myarray.push({productId : 2 , price : 200 , discount : 20});
myarray.push({productId : 3 , price : 300 , discount : 30});
priceListMap.set(1 , this.myarray);
myarray = null;

(code in playground)

If you actually want to build a complete URI, try URIBuilder from Apache Http Compoments (HttpClient 4).

This does not actually answer the question, but it answered the one I had when I found this question.

Use:

if (function_exists('curl_file_create')) { // php 5.5+
  $cFile = curl_file_create($file_name_with_full_path);
} else { // 
  $cFile = '@' . realpath($file_name_with_full_path);
}
$post = array('extra_info' => '123456','file_contents'=> $cFile);
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$target_url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$result=curl_exec ($ch);
curl_close ($ch);

You can also refer:

http://blog.derakkilgo.com/2009/06/07/send-a-file-via-post-with-curl-and-php/

Important hint for PHP 5.5+:

Now we should use https://wiki.php.net/rfc/curl-file-upload but if you still want to use this deprecated approach then you need to set curl_setopt($ch, CURLOPT_SAFE_UPLOAD, false);

Having gone through a ridiculous amount of time trying to solve one of these, and I definitely can see where most of these answers could be correct in some cases, my situation was not all that uncommon.

I was trying to deploy to the app store to test with TestFlight. A previous developer, no longer part of the project or company, had created the IOS Distribution Certificate. What xcode was trying to tell me was that yes, the certificate was in the member center, but dude you totally can't use it because it's not yours. I didn't have the private key needed to sign with it and no amount of refreshes, restarts, revokes were going to help me. You need a developer and distribution certificate to upload to the app store.

The solution was to create a new production distribution certificate in the member center, using a new signing request from my keychain. This process is documented well and described while you create the cert online. Once done, refresh your account in xcode to download to your keychain and you will be golden. I hope this helps somebody!

The package BBmisc now contains the function capitalizeStrings.

library("BBmisc")
capitalizeStrings(c("the taIl", "wags The dOg", "That Looks fuNny!")
    , all.words = TRUE, lower.back = TRUE)
[1] "The Tail"          "Wags The Dog"      "That Looks Funny!"

i found this way useful also.

import tkinter.filedialog
from_filename = tkinter.filedialog.askopenfilename()  

here a window will appear so you can browse till you find the file , you click on it then you can continue using open , and read .

from_file = open(from_filename, 'r')
contents = from_file.read()
contents

update

As BrianCampbell points out here, SQLite 3.7.11 and above now supports the simpler syntax of the original post. However, the approach shown is still appropriate if you want maximum compatibility across legacy databases.

original answer

If I had privileges, I would bump river's reply: You can insert multiple rows in SQLite, you just need different syntax. To make it perfectly clear, the OPs MySQL example:

INSERT INTO 'tablename' ('column1', 'column2') VALUES
  ('data1', 'data2'),
  ('data1', 'data2'),
  ('data1', 'data2'),
  ('data1', 'data2');

This can be recast into SQLite as:

     INSERT INTO 'tablename'
          SELECT 'data1' AS 'column1', 'data2' AS 'column2'
UNION ALL SELECT 'data1', 'data2'
UNION ALL SELECT 'data1', 'data2'
UNION ALL SELECT 'data1', 'data2'

a note on performance

I originally used this technique to efficiently load large datasets from Ruby on Rails. However, as Jaime Cook points out, it's not clear this is any faster wrapping individual INSERTs within a single transaction:

BEGIN TRANSACTION;
INSERT INTO 'tablename' table VALUES ('data1', 'data2');
INSERT INTO 'tablename' table VALUES ('data3', 'data4');
...
COMMIT;

If efficiency is your goal, you should try this first.

a note on UNION vs UNION ALL

As several people commented, if you use UNION ALL (as shown above), all rows will be inserted, so in this case, you'd get four rows of data1, data2. If you omit the ALL, then duplicate rows will be eliminated (and the operation will presumably be a bit slower). We're using UNION ALL since it more closely matches the semantics of the original post.

in closing

P.S.: Please +1 river's reply, as it presented the solution first.

The problem is that you're (probably) trying to plot a vector that consists exclusively of missing (NA) values. Here's an example:

> x=rep(NA,100)
> y=rnorm(100)
> plot(x,y)
Error in plot.window(...) : need finite 'xlim' values
In addition: Warning messages:
1: In min(x) : no non-missing arguments to min; returning Inf
2: In max(x) : no non-missing arguments to max; returning -Inf

In your example this means that in your line plot(costs,pseudor2,type="l"), costs is completely NA. You have to figure out why this is, but that's the explanation of your error.

From comments:

Scott C Wilson: Another possible cause of this message (not in this case, but in others) is attempting to use character values as X or Y data. You can use the class function to check your x and Y values to be sure if you think this might be your issue.

stevec: Here is a quick and easy solution to that problem (basically wrap x in as.factor(x))

npm set registry http://85.10.209.91/

(this proxy fetches the original data from registry.npmjs.org and manipulates the tarball urls to fix the tarball file structure issue).

The other solutions seem to have outdated versions.

I searched for many pages of the web through of the Google and here on the Stack Overflow, but nothing suggested resolved my problem.

After many attempts, I've changed my way of to test that controller. Then I have discovered that the problem occurs always which I reopened the page through of the Ctrl + Shift + T shortcut in Chrome. So the page ran, but without a parent window reference, and because this can't be closed.

You should prefer Object Mapper instead. Here is the link for the same : Object Mapper - Spring MVC way of Obect to JSON

If you are using oc4j to deploy the ear.

Make sure you set in the project the correct path for deploy.home=

You can fiind deploy.home in common.properties file

The oc4j needs to reload the new created class in the ear so that the server class and the client class have the same serialVersionUID

RobW's answers here and elsewhere were very helpful, but I found my needs to be much simpler. I've answered this elsewhere, but perhaps it will be useful here also.

I have a method where I form an HTML string to be loaded in a UIWebView:

NSString *urlString = [NSString stringWithFormat:@"https://www.youtube.com/embed/%@",videoID];

preparedHTML = [NSString stringWithFormat:@"<html><body style='background:none; text-align:center;'><script type='text/javascript' src='http://www.youtube.com/iframe_api'></script><script type='text/javascript'>var player; function onYouTubeIframeAPIReady(){player=new YT.Player('player')}</script><iframe id='player' class='youtube-player' type='text/html' width='%f' height='%f' src='%@?rel=0&showinfo=0&enablejsapi=1' style='text-align:center; border: 6px solid; border-radius:5px; background-color:transparent;' rel=nofollow allowfullscreen></iframe></body></html>", 628.0f, 352.0f, urlString];

You can ignore the styling stuff in the preparedHTML string. The important aspects are:

• Using the API to create the "YT.player" object. At one point, I only had the video in the iFrame tag and that prevented me from referencing the "player" object later with JS.
• I've seen a few examples on the web where the first script tag (the one with the iframe_api src tag) is omitted, but I definitely needed that to get this working.
• Creating the "player" variable at the beginning of the API script. I have also seen some examples that have omitted that line.
• Adding an id tag to the iFrame to be referenced in the API script. I almost forgot that part.
• Adding "enablejsapi=1" to the end of the iFrame src tag. That hung me up for a while, as I initially had it as an attribute of the iFrame tag, which does not work/did not work for me.

When I need to pause the video, I just run this:

[webView stringByEvaluatingJavaScriptFromString:@"player.pauseVideo();"];

Hope that helps!

You should implement an LRU cache manager when dealing with bitmap

http://developer.android.com/reference/android/util/LruCache.html http://developer.android.com/training/displaying-bitmaps/cache-bitmap.html When should I recycle a bitmap using LRUCache?

OR

Use a tier library like Universal Image Loader :

https://github.com/nostra13/Android-Universal-Image-Loader

EDIT :

Now when dealing with images and most of the time with bitmap I use Glide which let you configure a Glide Module and a LRUCache

https://github.com/bumptech/glide

Where it is documented:

From the API documentation under the has_many association in "Module ActiveRecord::Associations::ClassMethods"

collection.build(attributes = {}, …) Returns one or more new objects of the collection type that have been instantiated with attributes and linked to this object through a foreign key, but have not yet been saved. Note: This only works if an associated object already exists, not if it‘s nil!

The answer to building in the opposite direction is a slightly altered syntax. In your example with the dogs,

Class Dog
   has_many :tags
   belongs_to :person
end

Class Person
  has_many :dogs
end

d = Dog.new
d.build_person(:attributes => "go", :here => "like normal")

or even

t = Tag.new
t.build_dog(:name => "Rover", :breed => "Maltese")

You can also use create_dog to have it saved instantly (much like the corresponding "create" method you can call on the collection)

How is rails smart enough? It's magic (or more accurately, I just don't know, would love to find out!)

I've found yet another reason for spy to call the original method.

Someone had the idea to mock a final class, and found about MockMaker:

As this works differently to our current mechanism and this one has different limitations and as we want to gather experience and user feedback, this feature had to be explicitly activated to be available ; it can be done via the mockito extension mechanism by creating the file src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker containing a single line: mock-maker-inline

Source: https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2#mock-the-unmockable-opt-in-mocking-of-final-classesmethods

After I merged and brought that file to my machine, my tests failed.

I just had to remove the line (or the file), and spy() worked.

Besides putting the correct entries in your .gitignore file, if you're trying to ignore something already added to the repo, you have to do git rm -r /path/to/dir and commit that before you add the dir to your .gitignore file. Otherwise the only thing git will ignore is your ignore directive.

In the .NET world there are two types of CLRs, "full" CLRs and Core CLRs, and these are quite different things.

There are two "full" CLR implementations, the Microsoft native .NET CLR (for Windows) and the Mono CLR (which itself has implementations for Windows, linux and unix (Mac OS X and FreeBSD)). A full CLR is exactly that - everything, pretty much, that you need. As such, "full" CLRs tend to be large in size.

Core CLRs are on the other hand are cut down, and much smaller. Because they are only a core implementation, they are unlikely to have everything you need in them, so with Core CLRs you add feature sets to the CLR that your specific software product uses, using NuGet. There are Core CLR implementations for Windows, linux (various) and unix (Mac OS X and FreeBSD) in the mix. Microsoft have or are refactoring the .NET framework libraries for Core CLR too, to make them more portable for the core context. Given mono's presence on *nix OSs it would be a surprise if the Core CLRs for *nix did not include some mono code base, but only the Mono community and Microsoft could tell us that for sure.

Also, I'd concur with Nico in that Core CLRs are new -- it's at RC2 at the moment I think. I wouldn't depend on it for production code yet.

To answer your question you could delivery your site on linux using Core CLR or Mono, and these are two different ways of doing it. If you want a safe bet right now I'd go with mono on linux, then port if you want to later, to Core.

The command for your rescue is git clean.

If you are using a new, dedicated, user account... It is also worth checking that the password for that account has not expired, as that will also cause this 500.19 permissions issue.

The question is rather vague. If you meant “how do I write a program so that a thread stops running when I want it to”, then various other responses should be helpful. But if you meant “I have an emergency with a server I cannot restart right now and I just need a particular thread to die, come what may”, then you need an intervention tool to match monitoring tools like jstack.

For this purpose I created jkillthread. See its instructions for usage.

If-elseif-else can be written as a nested if-else. These are (logically speaking) equivalent:

if (A) 
{
    doA();
}
else if (B)
{
    doB();
}
else if (C)
{
    doC();
}
else
{
    doX();
}

is the same as:

if (A) 
{
    doA();
}
else
{
    if (B)
    {
        doB();
    }
    else
    {
         if (C)
         {
             doC();
         }
         else
         {
             doX();
         }
    }
}

The result is that ultimately only one of doA, doB, doC, or doX will be evaluated.

It's very easy to write that yourself, and that way you have more control over things.. As the other answers say, TypeScript is not aimed at adding runtime types or functionality.

Map:

class Map<T> {
    private items: { [key: string]: T };

    constructor() {
        this.items = {};
    }

    add(key: string, value: T): void {
        this.items[key] = value;
    }

    has(key: string): boolean {
        return key in this.items;
    }

    get(key: string): T {
        return this.items[key];
    }
}

List:

class List<T> {
    private items: Array<T>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(value);
    }

    get(index: number): T {
        return this.items[index];
    }
}

I haven't tested (or even tried to compile) this code, but it should give you a starting point.. you can of course then change what ever you want and add the functionality that YOU need...

As for your "special needs" from the List, I see no reason why to implement a linked list, since the javascript array lets you add and remove items.
Here's a modified version of the List to handle the get prev/next from the element itself:

class ListItem<T> {
    private list: List<T>;
    private index: number;

    public value: T;

    constructor(list: List<T>, value: T, index: number) {
        this.list = list;
        this.index = index;
        this.value = value;
    }

    prev(): ListItem<T> {
        return this.list.get(this.index - 1);
    }

    next(): ListItem<T> {
        return this.list.get(this.index + 1);   
    }
}

class List<T> {
    private items: Array<ListItem<T>>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(new ListItem<T>(this, value, this.size()));
    }

    get(index: number): ListItem<T> {
        return this.items[index];
    }
}

Here too you're looking at untested code..

Hope this helps.

Edit - as this answer still gets some attention

Javascript has a native Map object so there's no need to create your own:

let map = new Map();
map.set("key1", "value1");
console.log(map.get("key1")); // value1

Converting the lists to Guava's Multiset works very well. They are compared regardless of their order and duplicate elements are taken into account as well.

static <T> boolean equalsIgnoreOrder(List<T> a, List<T> b) {
    return ImmutableMultiset.copyOf(a).equals(ImmutableMultiset.copyOf(b));
}

assert equalsIgnoreOrder(ImmutableList.of(3, 1, 2), ImmutableList.of(2, 1, 3));
assert !equalsIgnoreOrder(ImmutableList.of(1), ImmutableList.of(1, 1));

You can do it in two different ways.

Option 1: The -eq operator

>$a = "is"
>$b = "fission"
>$c = "is"
>$a -eq $c
True
>$a -eq $b
False

Option 2: The .Equals() method of the string object. Because strings in PowerShell are .Net System.String objects, any method of that object can be called directly.

>$a.equals($b)
False
>$a.equals($c)
True
>$a|get-member -membertype method

List of System.String methods follows.

The strpos() finds the offset of the underscore, then substr grabs everything from that index plus 1, onwards.

$data = "123_String";    
$whatIWant = substr($data, strpos($data, "_") + 1);    
echo $whatIWant;

If you also want to check if the underscore character (_) exists in your string before trying to get it, you can use the following:

if (($pos = strpos($data, "_")) !== FALSE) { 
    $whatIWant = substr($data, $pos+1); 
}

This kind of query should work - after rewriting with explicit JOIN syntax:

SELECT something
FROM   master      parent
JOIN   master      child ON child.parent_id = parent.id
LEFT   JOIN second parentdata ON parentdata.id = parent.secondary_id
LEFT   JOIN second childdata ON childdata.id = child.secondary_id
WHERE  parent.parent_id = 'rootID'

The tripping wire here is that an explicit JOIN binds before "old style" CROSS JOIN with comma (,). I quote the manual here:

In any case JOIN binds more tightly than the commas separating FROM-list items.

After rewriting the first, all joins are applied left-to-right (logically - Postgres is free to rearrange tables in the query plan otherwise) and it works.

Just to make my point, this would work, too:

SELECT something
FROM   master parent
LEFT   JOIN second parentdata ON parentdata.id = parent.secondary_id
,      master child
LEFT   JOIN second childdata ON childdata.id = child.secondary_id
WHERE  child.parent_id = parent.id
AND    parent.parent_id = 'rootID'

But explicit JOIN syntax is generally preferable, as your case illustrates once again.

And be aware that multiple (LEFT) JOIN can multiply rows:

• Two SQL LEFT JOINS produce incorrect result

Call apply and bind. and how they are different.

Lets learn call and apply using any daily terminology.

You have three automobiles your_scooter , your_car and your_jet which start with the same mechanism (method). We created an object automobile with a method push_button_engineStart.

var your_scooter, your_car, your_jet;
var automobile = {
        push_button_engineStart: function (runtime){
        console.log(this.name + "'s" + ' engine_started, buckle up for the ride for ' + runtime + " minutes");
    }
}

Lets understand when is call and apply used. Lets suppose that you are an engineer and you have your_scooter, your_car and your_jet which did not come with a push_button_engine_start and you wish to use a third party push_button_engineStart.

If you run the following lines of code, they will give an error. WHY?

//your_scooter.push_button_engineStart();
//your_car.push_button_engineStart();
//your_jet.push_button_engineStart();


automobile.push_button_engineStart.apply(your_scooter,[20]);
automobile.push_button_engineStart.call(your_jet,10);
automobile.push_button_engineStart.call(your_car,40);

So the above example is successfully gives your_scooter, your_car, your_jet a feature from automobile object.

Let's dive deeper Here we will split the above line of code. automobile.push_button_engineStart is helping us to get the method being used.

Further we use apply or call using the dot notation. automobile.push_button_engineStart.apply()

Now apply and call accept two parameters.

1. context
2. arguments

So here we set the context in the final line of code.

automobile.push_button_engineStart.apply(your_scooter,[20])

Difference between call and apply is just that apply accepts parameters in the form of an array while call simply can accept a comma separated list of arguments.

what is JS Bind function?

A bind function is basically which binds the context of something and then stores it into a variable for execution at a later stage.

Let's make our previous example even better. Earlier we used a method belonging to the automobile object and used it to equip your_car, your_jet and your_scooter. Now lets imagine we want to give a separate push_button_engineStart separately to start our automobiles individually at any later stage of the execution we wish.

var scooty_engineStart = automobile.push_button_engineStart.bind(your_scooter);
var car_engineStart = automobile.push_button_engineStart.bind(your_car);
var jet_engineStart = automobile.push_button_engineStart.bind(your_jet);


setTimeout(scooty_engineStart,5000,30);
setTimeout(car_engineStart,10000,40);
setTimeout(jet_engineStart,15000,5);

still not satisfied?

Let's make it clear as teardrop. Time to experiment. We will go back to call and apply function application and try storing the value of the function as a reference.

The experiment below fails because call and apply are invoked immediately, hence, we never get to the stage of storing a reference in a variable which is where bind function steals the show

var test_function = automobile.push_button_engineStart.apply(your_scooter);

Either remove one } from end of responseText;}} or from the end of the line

As a follow on, you could select "all nodes with a particular attribute" like this:

//*[@id='4']

As of now there is just two property for firefox scrollbar customization is available .

scrollbar-color & scrollbar width

scrollbar-color:red yellow; (track,thumb) scrollbar-width:5px;

HTML

<div class="demo">

css

.demo {
overflow-y:scroll;
}

.demo {
scrollbar-color:red yellow;
scrollbar-width:5px;
}

You need to loop over loadDT.Columns, like this:

foreach (DataColumn column in loadDT.Columns)
{
    Console.Write("Item: ");
    Console.Write(column.ColumnName);
    Console.Write(" ");
    Console.WriteLine(row[column]);
}

You could prove to yourself that there is no other difference by trying to define a function in a struct. I remember even my college professor who was teaching about structs and classes in C++ was surprised to learn this (after being corrected by a student). I believe it, though. It was kind of amusing. The professor kept saying what the differences were and the student kept saying "actually you can do that in a struct too". Finally the prof. asked "OK, what is the difference" and the student informed him that the only difference was the default accessibility of members.

A quick Google search suggests that POD stands for "Plain Old Data".

Change:

x.length

to:

x.options.length

Link to fiddle

And I agree with Abraham - you might want to use text instead of value

Update
The reason your fiddle didn't work was because you chose the option: "onLoad" instead of: "No wrap - in "

If you are debugging or similar - In chrome developer tools, you can simply use

$x('/html/.//div[@id="text"]')

• Get the distance from the top of the given element
• Add the height of the same given element. This will tell you the total number from the top of the screen to the end of the given element.

• Then all you have to do is subtract that from total document height

  jQuery(function () {
      var documentHeight = jQuery(document).height();
      var element = jQuery('#you-element');
      var distanceFromBottom = documentHeight - (element.position().top + element.outerHeight(true));
      alert(distanceFromBottom)
  });
  

obj1 != null  

is the right way.

String defines IsNullOrEmpty as a nicer way to say

obj1 == null || obj == String.Empty

so it does more than just check for nullity.

There may be other classes that define a method to check for a sematically "blank or null" object, but that would depend on the semantics of the class, and is by no means universal.

It's also possible to create extension method to do this kind of thing if it helps the readability of your code. For example, a similar approach to collections:

public static bool IsNullOrEmpty (this ICollection collection)
{
    return collection == null || collection.Count == 0;
}

You can learn some tutorials for JSP page direct access database (mysql) here

Notes:

• import sql tag library in jsp page

  <%@ taglib uri="http://java.sun.com/jsp/jstl/sql" prefix="sql"%>

• then set datasource on page

  <sql:setDataSource var="ds" driver="com.mysql.jdbc.Driver" url="jdbc:mysql://<yourhost>/<yourdb>" user="<user>" password="<password>"/>
  

• Now query what you want on page

  <sql:query dataSource="${ds}" var="result"> //ref  defined 'ds'
      SELECT * from <your-table>;
  </sql:query>
  

• Finally you can populate dropdowns on page using c:forEach tag to iterate result rows in select element

  <c:forEach var="row" items="${result.rows}"> //ref set var 'result' <option value='<c:out value="${row.key}"/>'><c:out value="${row.value}"/</option> </c:forEach>

You could also do something like this :

const str = "hi, there"_x000D_
_x000D_
const res = str.includes("hello") || str.includes("hi") || str.includes('howdy');_x000D_
_x000D_
console.log(res);

Whenever one of your includes return true, value will be true, otherwise, it's going to be false. This works perfectly fine with ES6.

In plain JS add { passive: false } as third argument

document.addEventListener('wheel', function(e) {
    e.preventDefault();
    doStuff(e);
}, { passive: false });

I think this code will resolve your issue. Copy and paste this code on your MainActivity.java

@Override
protected void onCreate(Bundle savedInstanceState) {                          
    super.onCreate(savedInstanceState);

    View decorView = getWindow().getDecorView();
    decorView.setOnSystemUiVisibilityChangeListener
    (new View.OnSystemUiVisibilityChangeListener() {
        @Override
        public void onSystemUiVisibilityChange(int visibility) {

            if ((visibility & View.SYSTEM_UI_FLAG_FULLSCREEN) == 0) {
                hideNavigationBar();
            } 
        }
    });
}



private void hideNavigationBar() {
   getWindow().getDecorView().setSystemUiVisibility(
        View.SYSTEM_UI_FLAG_HIDE_NAVIGATION|
        View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY);
}

It will works on Android-10. I hope it will helps.

http://www.php.net/mysql_query says "mysql_query() returns a resource".

http://www.php.net/json_encode says it can encode any value "except a resource".

You need to iterate through and collect the database results in an array, then json_encode the array.

There is another one way, in which you can get indexPath of the cell where your button was pressed:

using usual action selector like:

 UIButton *btn = ....;
    [btn addTarget:self action:@selector(yourFunction:) forControlEvents:UIControlEventTouchUpInside];

and then in in yourFunction:

   - (void) yourFunction:(id)sender {

    UIButton *button = sender;
    CGPoint center = button.center;
    CGPoint rootViewPoint = [button.superview convertPoint:center toView:self.tableView];
    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:rootViewPoint];
    //the rest of your code goes here
    ..
}

since you get an indexPath it becames much simplier.

var fileInput = $('#uploadCaptureInputFile');
fileInput.replaceWith(fileInput.val('').clone(true));

The most Simplest solution would be

In most cases one will only check internet connection if he/she wants to connect to the remote server so the simple and best solution would be pinging your server as following.

public boolean isConnected() {
    final String command = "ping -c 1 yourExmapleDomain.com";
    boolean isConnected = false;
    try {
        isConnected = Runtime.getRuntime().exec(command).waitFor() == 0;
    } catch (InterruptedException e) {
        e.printStackTrace();
    } catch (IOException e) {
        e.printStackTrace();
    }
    return isConnected;
}

For jQuery, do you mean like this?

$('#object').css('display');

You can check it like this:

if($('#object').css('display') === 'block')
{
    //do something
}
else
{
    //something else
}

sysctl -w net.ipv4.tcp_timestamps=1
sysctl -w net.ipv4.tcp_tw_recycle=1

Using function Find is cleaner way.

MyClass item = MyList.Find(item => item.name == "foo");
if (item != null) // check item isn't null
{
 ....
}

You can include the ruby mathn module.

require 'mathn'

This way, you are going to be able to make the division normally.

1/2              #=> (1/2)
(1/2) ** 3       #=> (1/8)
1/3*3            #=> 1
Math.sin(1/2)    #=> 0.479425538604203

This way, you get exact division (class Rational) until you decide to apply an operation that cannot be expressed as a rational, for example Math.sin.

I wanted to see all the indices for the colnames because I needed to do a complicated column rearrangement, so I printed the colnames as a dataframe. The rownames are the indices.

as.data.frame(colnames(df))

1 A
2 B
3 C

You can even say:

The accepted answer works, but has three problems:

• It uses an undocumented Spring Data feature when naming the custom implementation as AccountRepositoryImpl. The documentation clearly states that it has to be called AccountRepositoryCustomImpl, the custom interface name plus Impl
• You cannot use constructor injection, only @Autowired, that are considered bad practice
• You have a circular dependency inside of the custom implementation (that's why you cannot use constructor injection).

I found a way to make it perfect, though not without using another undocumented Spring Data feature:

public interface AccountRepository extends AccountRepositoryBasic,
                                           AccountRepositoryCustom 
{ 
}

public interface AccountRepositoryBasic extends JpaRepository<Account, Long>
{
    // standard Spring Data methods, like findByLogin
}

public interface AccountRepositoryCustom 
{
    public void customMethod();
}

public class AccountRepositoryCustomImpl implements AccountRepositoryCustom 
{
    private final AccountRepositoryBasic accountRepositoryBasic;

    // constructor-based injection
    public AccountRepositoryCustomImpl(
        AccountRepositoryBasic accountRepositoryBasic)
    {
        this.accountRepositoryBasic = accountRepositoryBasic;
    }

    public void customMethod() 
    {
        // we can call all basic Spring Data methods using
        // accountRepositoryBasic
    }
}

Passing it a few ws will ignore the display width.

Array.prototype.avg=function(fn){
    fn =fn || function(e,i){return e};
    return (this.map(fn).reduce(function(a,b){return parseFloat(a)+parseFloat(b)},0) / this.length ) ; 
};

Then :

[ 1 , 2 , 3].avg() ;  //-> OUT : 2

[{age:25},{age:26},{age:27}].avg(function(e){return e.age}); // OUT : 26

DESCRIBE <table>; 

This is acutally a shortcut for:

SHOW COLUMNS FROM <table>;

In any case, there are three possible values for the "Key" attribute:

1. PRI
2. UNI
3. MUL

The meaning of PRI and UNI are quite clear:

• PRI => primary key
• UNI => unique key

The third possibility, MUL, (which you asked about) is basically an index that is neither a primary key nor a unique key. The name comes from "multiple" because multiple occurrences of the same value are allowed. Straight from the MySQL documentation:

If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

There is also a final caveat:

If more than one of the Key values applies to a given column of a table, Key displays the one with the highest priority, in the order PRI, UNI, MUL.

As a general note, the MySQL documentation is quite good. When in doubt, check it out!

Here is an example from my HOW TO Matlab page:

close all; clear all;

img   = imread('lena.tif','tif');
imagesc(img)
img   = fftshift(img(:,:,2));
F     = fft2(img);

figure;

imagesc(100*log(1+abs(fftshift(F)))); colormap(gray); 
title('magnitude spectrum');

figure;
imagesc(angle(F));  colormap(gray);
title('phase spectrum');

This gives the magnitude spectrum and phase spectrum of the image. I used a color image, but you can easily adjust it to use gray image as well.

ps. I just noticed that on Matlab 2012a the above image is no longer included. So, just replace the first line above with say

img = imread('ngc6543a.jpg');

and it will work. I used an older version of Matlab to make the above example and just copied it here.

On the scaling factor

When we plot the 2D Fourier transform magnitude, we need to scale the pixel values using log transform to expand the range of the dark pixels into the bright region so we can better see the transform. We use a c value in the equation

s = c log(1+r) 

There is no known way to pre detrmine this scale that I know. Just need to try different values to get on you like. I used 100 in the above example.

CREATE PROCEDURE pr_emp(dept_id IN NUMBER,vv_ename out varchar2  )
 AS
 v_ename emp%rowtype;
CURSOR c_emp IS
    SELECT ename
    FROM emp where deptno=dept_id;
 BEGIN
     OPEN c;
     loop
        FETCH c_emp INTO v_ename;
        return v_ename; 
        vv_ename := v_ename 
        exit when c_emp%notfound;
     end loop;
     CLOSE c_emp;


 END pr_emp;

This is my own plugin (will position the element in top of the the list. Specially for overflow-y : auto. May not work with overflow-x!):

NOTE: elem is the HTML selector of an element which the page will be scrolled to. Anything supported by jQuery, like: #myid, div.myclass, $(jquery object), [dom object], etc.

jQuery.fn.scrollTo = function(elem, speed) { 
    $(this).animate({
        scrollTop:  $(this).scrollTop() - $(this).offset().top + $(elem).offset().top 
    }, speed == undefined ? 1000 : speed); 
    return this; 
};

If you don't need it to be animated, then use:

jQuery.fn.scrollTo = function(elem) { 
    $(this).scrollTop($(this).scrollTop() - $(this).offset().top + $(elem).offset().top); 
    return this; 
};

How to use:

$("#overflow_div").scrollTo("#innerItem");
$("#overflow_div").scrollTo("#innerItem", 2000); //custom animation speed 

Note: #innerItem can be anywhere inside #overflow_div. It doesn't really have to be a direct child.

Tested in Firefox (23) and Chrome (28).

You do not have to use final, but the final is making clear to everyone else - including the compiler - that this is a constant, and that's the good practice in it.

Why people doe that even if the constant will be used only in one place and only in the same class: Because in many cases it still makes sense. If you for example know it will be final during program run, but you intend to change the value later and recompile (easier to find), and also might use it more often later-on. It is also informing other programmers about the core values in the program flow at a prominent and combined place.

An aspect the other answers are missing out unfortunately, is that using the combination of public final needs to be done very carefully, especially if other classes or packages will use your class (which can be assumed because it is public).

Here's why:

1. Because it is declared as final, the compiler will inline this field during compile time into any compilation unit reading this field. So far, so good.
2. What people tend to forget is, because the field is also declared public, the compiler will also inline this value into any other compile unit. That means other classes using this field.

What are the consequences?

Imagine you have this:

class Foo {
  public static final String VERSION = "1.0";
}

class Bar {
  public static void main(String[] args) {
    System.out.println("I am using version " + Foo.VERSION);
  }
}

After compiling and running Bar, you'll get:

I am using version 1.0

Now, you improve Foo and change the version to "1.1". After recompiling Foo, you run Bar and get this wrong output:

I am using version 1.0

This happens, because VERSION is declared final, so the actual value of it was already in-lined in Bar during the first compile run. As a consequence, to let the example of a public static final ... field propagate properly after actually changing what was declared final (you lied!;), you'd need to recompile every class using it.

I've seen this a couple of times and it is really hard to debug.

If by final you mean a constant that might change in later versions of your program, a better solution would be this:

class Foo {
  private static String version = "1.0";
  public static final String getVersion() {
    return version;
  }
}

The performance penalty of this is negligible, since JIT code generator will inline it at run-time.

create resource file in drawable

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
android:shape="rectangle">
<solid android:color="#3b5998" />
<cornersandroid:radius="15dp"/>

The above solution will modify the infs that are not in the target columns. To remedy that,

lst = [np.inf, -np.inf]
to_replace = {v: lst for v in ['col1', 'col2']}
df.replace(to_replace, np.nan)

You can use HTML5 for this:

<video autoplay></video>
<script>
  var onFailSoHard = function(e) {
    console.log('Reeeejected!', e);
  };

  // Not showing vendor prefixes.
  navigator.getUserMedia({video: true, audio: true}, function(localMediaStream) {
    var video = document.querySelector('video');
    video.src = window.URL.createObjectURL(localMediaStream);

    // Note: onloadedmetadata doesn't fire in Chrome when using it with getUserMedia.
    // See crbug.com/110938.
    video.onloadedmetadata = function(e) {
      // Ready to go. Do some stuff.
    };
  }, onFailSoHard);
</script>

None of the other answers dealt with the case of using .children() or .find(">") to only search for immediate children of a parent element. So, I created a jsPerf test to find out, using three different ways to distinguish children.

As it happens, even when using the extra ">" selector, .find() is still a lot faster than .children(); on my system, 10x so.

So, from my perspective, there does not appear to be much reason to use the filtering mechanism of .children() at all.

You can allow database access on the main thread but only for debugging purpose, you shouldn't do this on production.

Here is the reason.

Note: Room doesn't support database access on the main thread unless you've called allowMainThreadQueries() on the builder because it might lock the UI for a long period of time. Asynchronous queries—queries that return instances of LiveData or Flowable—are exempt from this rule because they asynchronously run the query on a background thread when needed.

public class colorString
{

public static void main( String[] args )
{
    new colorString();   

}

public colorString( )
{
    kFrame f = new kFrame();
    f.setSize( 400, 400 );
    f.setVisible( true );
}

private static class kFrame extends JFrame
{
    @Override
    public void paint(Graphics g) 
    {
        super.paint( g );
        Graphics2D g2d = (Graphics2D)g;
        g2d.setColor( new Color(255, 0, 0) );
        g2d.drawString("red red red red red", 100, 100 );
    }
}
}

moment.js is great but sometimes you don't want to pull a large number of dependencies for simple things.

The following works as well:

var tzoffset = (new Date()).getTimezoneOffset() * 60000; //offset in milliseconds
var localISOTime = (new Date(Date.now() - tzoffset)).toISOString().slice(0, -1);
// => '2015-01-26T06:40:36.181'

The slice(0, -1) gets rid of the trailing Z which represents Zulu timezone and can be replaced by your own.

Alternatively you can use img2pdf to convert images to pdf. Install it on Debian or Ubuntu with:

sudo apt install img2pdf

Convert one or more images to pdf:

img2pdf img.jpg -o output.pdf

It uses a different mechanism than imagemagick to embed the image into the pdf. When possible Img2pdf embeds the image directly into the pdf, without decoding and recoding the image.

A function inside of a function is commonly used for closures.

(There is a lot of contention over what exactly makes a closure a closure.)

Here's an example using the built-in sum(). It defines start once and uses it from then on:

def sum_partial(start):
    def sum_start(iterable):
        return sum(iterable, start)
    return sum_start

In use:

>>> sum_with_1 = sum_partial(1)
>>> sum_with_3 = sum_partial(3)
>>> 
>>> sum_with_1
<function sum_start at 0x7f3726e70b90>
>>> sum_with_3
<function sum_start at 0x7f3726e70c08>
>>> sum_with_1((1,2,3))
7
>>> sum_with_3((1,2,3))
9

Built-in python closure

functools.partial is an example of a closure.

From the python docs, it's roughly equivalent to:

def partial(func, *args, **keywords):
    def newfunc(*fargs, **fkeywords):
        newkeywords = keywords.copy()
        newkeywords.update(fkeywords)
        return func(*(args + fargs), **newkeywords)
    newfunc.func = func
    newfunc.args = args
    newfunc.keywords = keywords
    return newfunc

(Kudos to @user225312 below for the answer. I find this example easier to figure out, and hopefully will help answer @mango's comment.)

The reason for the error is that even though the image did not have any tag, there still exists a container created on that image which might be in the exited state. So you need to ensure that you have stopped and deleted all containers created on those images. The following command helps you in removing all containers that are not running:

docker rm `docker ps -aq --no-trunc --filter "status=exited"`

Now this removes all the dangling non-intermediate <none> images:

docker rmi `docker images --filter 'dangling=true' -q --no-trunc`

Note: To stops all running containers:

docker stop `docker ps -q`

git fetch origin
git checkout --track -b local_branch_name origin/branch_name

Using PostgreSQL like (see accepted answer above) somehow didn't work for me although cases matched, but ilike (case insensisitive like) does.

C or C++ will not check the bounds of an array access.

You are allocating the array on the stack. Indexing the array via array[3] is equivalent to *(array + 3), where array is a pointer to &array[0]. This will result in undefined behavior.

One way to catch this sometimes in C is to use a static checker, such as splint. If you run:

splint +bounds array.c

on,

int main(void)
{
    int array[1];

    array[1] = 1;

    return 0;
}

then you will get the warning:

array.c: (in function main) array.c:5:9: Likely out-of-bounds store: array[1] Unable to resolve constraint: requires 0 >= 1 needed to satisfy precondition: requires maxSet(array @ array.c:5:9) >= 1 A memory write may write to an address beyond the allocated buffer.

There are numerous examples that show how to do this with a private CoreTelephony call: _CTServerConnectionSetVibratorState, but it's really not a sensible course of action since your app will get rejected for abusing the vibrate feature like that. Just don't do it.

Since Python 3.5, things are much easier with os.scandir()

with os.scandir(path) as it:
    for entry in it:
        if entry.name.endswith(".asm") and entry.is_file():
            print(entry.name, entry.path)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

I recently discovered the rather useful sweep function and add it here for the sake of completeness:

sweep

The basic idea is to sweep through an array row- or column-wise and return a modified array. An example will make this clear (source: datacamp):

Let's say you have a matrix and want to standardize it column-wise:

dataPoints <- matrix(4:15, nrow = 4)

# Find means per column with `apply()`
dataPoints_means <- apply(dataPoints, 2, mean)

# Find standard deviation with `apply()`
dataPoints_sdev <- apply(dataPoints, 2, sd)

# Center the points 
dataPoints_Trans1 <- sweep(dataPoints, 2, dataPoints_means,"-")

# Return the result
dataPoints_Trans1
##      [,1] [,2] [,3]
## [1,] -1.5 -1.5 -1.5
## [2,] -0.5 -0.5 -0.5
## [3,]  0.5  0.5  0.5
## [4,]  1.5  1.5  1.5

# Normalize
dataPoints_Trans2 <- sweep(dataPoints_Trans1, 2, dataPoints_sdev, "/")

# Return the result
dataPoints_Trans2
##            [,1]       [,2]       [,3]
## [1,] -1.1618950 -1.1618950 -1.1618950
## [2,] -0.3872983 -0.3872983 -0.3872983
## [3,]  0.3872983  0.3872983  0.3872983
## [4,]  1.1618950  1.1618950  1.1618950

NB: for this simple example the same result can of course be achieved more easily by
apply(dataPoints, 2, scale)

The key is to keep the declarations of the variable in the header file and source file the same.

I use this trick

------sample.c------
#define sample_c
#include sample.h

(rest of sample .c)

------sample.h------
#ifdef sample_c
#define EXTERN
#else
#define EXTERN extern
#endif

EXTERN int x;

Sample.c is only compiled once and it defines the variables. Any file that includes sample.h is only given the "extern" of the variable; it does allocate space for that variable.

When you change the type of x, it will change for everybody. You won't need to remember to change it in the source file and the header file.

You can always refer to resources in your application directly by their JNDI name as configured in the container, but if you do so, essentially you are wiring the container-specific name into your code. This has some disadvantages, for example, if you'll ever want to change the name later for some reason, you'll need to update all the references in all your applications, and then rebuild and redeploy them.

<resource-ref> introduces another layer of indirection: you specify the name you want to use in the web.xml, and, depending on the container, provide a binding in a container-specific configuration file.

So here's what happens: let's say you want to lookup the java:comp/env/jdbc/primaryDB name. The container finds that web.xml has a <resource-ref> element for jdbc/primaryDB, so it will look into the container-specific configuration, that contains something similar to the following:

<resource-ref>
  <res-ref-name>jdbc/primaryDB</res-ref-name>
  <jndi-name>jdbc/PrimaryDBInTheContainer</jndi-name>
</resource-ref>

Finally, it returns the object registered under the name of jdbc/PrimaryDBInTheContainer.

The idea is that specifying resources in the web.xml has the advantage of separating the developer role from the deployer role. In other words, as a developer, you don't have to know what your required resources are actually called in production, and as the guy deploying the application, you will have a nice list of names to map to real resources.

I'd like to add something that hasn't been pointed out. Java doesn't take into account the values you have given the variables (2 and 3) in...

short a = 2; short b = 3; short c = a + b;

So as far as Java knows, you could done this...

short a = 32767; short b = 32767; short c = a + b;

Which would be outside the range of short, it autoboxes the result to an int becuase it's "possible" that the result will be more than a short but not more than an int. Int was chosen as a "default" because basically most people wont be hard coding values above 2,147,483,647 or below -2,147,483,648

Using LINQ's Union

Enumerable.Union(ListA,ListB);

or

ListA.Union(ListB);

There are indeed C# compilers for Android available. Even though I prefer developing Android Apps in Java, I can recommend MonoForAndroid. You find more information on http://xamarin.com/monoforandroid

new[] { ',', '.', ';', '\'', '@' }
.Aggregate("My name @is ,Wan.;'; Wan", (s, c) => s.Replace(c.ToString(), string.Empty)); 

The below works for me

dataframe[,"newName"] <- NA

Make sure to add "" for new name string.

RadioGroup radioGroup = (RadioGroup) findViewById(R.id.yourRadioGroup);     
    radioGroup.setOnClickListener(v -> {
                        // get selected radio button from radioGroup
                        int selectedId = radioGroup.getCheckedRadioButtonId();
                        // find the radiobutton by returned id
                        radioButton =  findViewById(selectedId);
                        String slectedValue=radioButton.getText()          
        });

And don't forget to create a __init__.py with each folder/subfolder (even if they are empty)

If you are adding the View programmatically, you can use yourLayout.addView(view, 1);

where 1 is the index.

If you see this intermittently on wifi or LAN, but your mobile internet connection seems ok, it is most likely your ISP's cheap gateway router is experiencing high traffic load.

You should trap these errors and display a reminder to the user to close any other apps using the network.

Test by running a couple of HD youtube videos on your desktop to reproduce, or just go to a busy Starbucks.

Subscript out of Range error occurs when you try to reference an Index for a collection that is invalid.

Most likely, the index in Windows does not actually include .xls. The index for the window should be the same as the name of the workbook displayed in the title bar of Excel.

As a guess, I would try using this:

Windows("Data Sheet - " & ComboBox_Month.Value & " " & TextBox_Year.Value).Activate

Basically you need following things to make location detector android app

• Location Listener, which detect current location
• Marker to add and animate when person moves
• Polyline to add path on person's movement
• Services for sending and receiving location
• Rest API / Firebase Realtime Database to store and fetch locations

Now if you write each of these module yourself then it needs much time and efforts. So it would be better to use ready resources that are being maintained already.

Using all these resources, you will be able to create an flawless android location detection app.

1. Location Listening

You will first need to listen for current location of user. You can use any of below libraries to quick start.

Google Play Location Samples

This library provide last known location, location updates

Location Manager

With this library you just need to provide a Configuration object with your requirements, and you will receive a location or a fail reason with all the stuff are described above handled.

Live Location Sharing

Use this open source repo of the Hypertrack Live app to build live location sharing experience within your app within a few hours. HyperTrack Live app helps you share your Live Location with friends and family through your favorite messaging app when you are on the way to meet up. HyperTrack Live uses HyperTrack APIs and SDKs.

2. Markers Library

Google Maps Android API utility library

• Marker clustering — handles the display of a large number of points
• Heat maps — display a large number of points as a heat map
• IconGenerator — display text on your Markers
• Poly decoding and encoding — compact encoding for paths, interoperability with Maps API web services
• Spherical geometry — for example: computeDistance, computeHeading, computeArea
• KML — displays KML data
• GeoJSON — displays and styles GeoJSON data

3. Polyline Libraries

DrawRouteMaps

If you want to add route maps feature in your apps you can use DrawRouteMaps to make you work more easier. This is lib will help you to draw route maps between two point LatLng.

trail-android

Simple, smooth animation for route / polylines on google maps using projections. (WIP)

Google-Directions-Android

This project allows you to calculate the direction between two locations and display the route on a Google Map using the Google Directions API.

A map demo app for quick start with maps

Greetings! I know this is an older post, but I found it through Google when searching for "javascript add large block of html as variable". I thought I'd post an alternate solution.

First, I'd recommend using single-quotes around the variable itself ... makes it easier to preserve double-quotes in the actual HTML code.

You can use a backslash to separate lines if you want to maintain a sense of formatting to the code:

var code = '<div class="my-class"> \
        <h1>The Header</h1> \
        <p>The paragraph of text</p> \
        <div class="my-quote"> \
            <p>The quote I\'d like to put in a div</p> \
        </div> \
    </div>';

Note: You'll obviously need to escape any single-quotes inside the code (e.g. inside the last 'p' tag)

Anyway, I hope that helps someone else that may be looking for the same answer I was ... Cheers!

foreach($_POST as $key=>$value)

}

It really depends on your usage pattern. A detailed benchmark between string.Join, string,Concat and string.Format can be found here: String.Format Isn't Suitable for Intensive Logging

(This is actually the same answer I gave to this question)

Following is the way to do it;

1. Create a background image that looks like a dropdown.
2. Switch off browser appearance
3. Align the background image on the select component

  .control select {  
    border-radius: 0px;
    appearance: none;
    -webkit-appearance: none;
    -moz-appearance: none;
    background-image: url("<your image>");
    background-repeat: no-repeat;
    background-position: 100%;
    background-size: 20px;
  }

var is a placeholder introduced for the anonymous types in C# 3.0 and LINQ.

As such, it allows writing LINQ queries for a fewer amount of columns within, let's say, a collection. No need to duplicate the information in memory, only load what's necessary to accomplish what you need to be done.

The use of var is not bad at all, as it is actually not a type, but as mentioned elsewhere, a placeholder for the type which is and has to be defined on the right-hand side of the equation. Then, the compiler will replace the keyword with the type itself.

It is particularly useful when, even with IntelliSense, the name of a type is long to type. Just write var, and instantiate it. The other programmers who will read your code afterward will easily understand what you're doing.

It's like using

public object SomeObject { get; set; }

instead of:

public object SomeObject {
    get {
        return _someObject;
    } 
    set {
        _someObject = value;
    }
}
private object _someObject;

Everyone knows what's the property's doing, as everyone knows what the var keyword is doing, and either examples tend to ease readability by making it lighter, and make it more pleasant for the programmer to write effective code.

I had a simllar problem. Main provider was antivirus "FortiClient" (antivirus + VPN CLient). When I disabled it - all update/checkout was made correctly

Support for TLS 1.0 and 1.1 was dropped for PyPI. If your system does not use a more recent version, it could explain your error.

Could you try reinstalling pip system-wide, to update your system dependencies to a newer version of TLS?

This seems to be related to Unable to install Python libraries

See Dominique Barton's answer:

Apparently pip is trying to access PyPI via HTTPS (which is encrypted and fine), but with an old (insecure) SSL version. Your system seems to be out of date. It might help if you update your packages.

On Debian-based systems I'd try:

apt-get update && apt-get upgrade python-pip

On Red Hat Linux-based systems:

yum update python-pip # (or python2-pip, at least on Red Hat Linux 7)

On Mac:

sudo easy_install -U pip

You can also try to update openssl separately.

Looking at your classpath you exclude src/main/resources and src/test/resources:

    <classpathentry excluding="**" kind="src" output="target/classes" path="src/main/resources"/>
    <classpathentry excluding="**" kind="src" output="target/test-classes" path="src/test/resources"/>

Is there a reason for it? Try not to exclude a classpath to spring-config.xml :)

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

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

You can remove the "bullets" by setting the "list-style-type: none;" Like

ul
{
    list-style-type: none;
}

OR

<ul class="menu custompozition4"  style="list-style-type: none;">
    <li class="item-507"><a href=#">Strategic Recruitment Solutions</a>
    </li>
    <li class="item-508"><a href="#">Executive Recruitment</a>

Connect to the server as "system" using SID. Execute this query:

select value from v$parameter where name like '%service_name%';

It worked for me.

Not a very good solution but one way is to redirect from the ROOT app to YourWebApp. For this you need to modify the ROOT index.html.

<html>
    <head>
        <title>Redirecting to /YourWebApp</title>
    </head>
    <body onLoad="javascript:window.location='YourWebApp';">
    </body>
</html>

OR

<html>
    <head>
        <title>Redirecting to /YourWebApp</title>
        <meta http-equiv="refresh" content="0;url=YourWebApp" />
    </head>
    <body>
    </body>
</html>

In addition to Mr. Yankowsky's answers, you could also use postDelayed(). This is available on any View (e.g., your card) and takes a Runnable and a delay period. It executes the Runnable after that delay.

It's better to use $(window).scroll() rather than $('#Eframe').on("mousewheel")

$('#Eframe').on("mousewheel") will not trigger if people manually scroll using up and down arrows on the scroll bar or grabbing and dragging the scroll bar itself.

$(window).scroll(function(){
    var scrollPos = $(document).scrollTop();
    console.log(scrollPos);
});

If #Eframe is an element with overflow:scroll on it and you want it's scroll position. I think this should work (I haven't tested it though).

$('#Eframe').scroll(function(){
    var scrollPos = $('#Eframe').scrollTop();
    console.log(scrollPos);
});

str_split can do the trick. Note that strings in PHP can be accessed just like a chars array, in most cases, you won't need to split your string into a "new" array.

Check this:

<?php
if (mysqli_num_rows(mysqli_query($con, sqlselectquery)) > 0)
{
    echo "found";
}
else
{
    echo "not found";
}
?>

The only information currently available is that Apple Pay will be available in ios8, but that doesn't shed any light on whether RFID tags or rather NFC tags specifically will be able to be detected/read.

IMO it would be a shortsighted move not to allow that possibility, but really the money is in Apple Pay, not necessarily in allowing developers access to those features - we've seen it before with tethering, Bluetooth SPP, and diminished access to certain functions.

...but then again, it's been about 5 hours since the first announcement.

While there might be a way I would tend to keep that kind of logic out of the Model. I agree that you shouldn't put that in the view (keep it skinny) but unless the model is returning a url as a piece of data to the controller, the routing stuff should be in the controller.

There are two primary ways that pandas makes selections from a DataFrame.

• By Label
• By Integer Location

The documentation uses the term position for referring to integer location. I do not like this terminology as I feel it is confusing. Integer location is more descriptive and is exactly what .iloc stands for. The key word here is INTEGER - you must use integers when selecting by integer location.

Before showing the summary let's all make sure that ...

.ix is deprecated and ambiguous and should never be used

There are three primary indexers for pandas. We have the indexing operator itself (the brackets []), .loc, and .iloc. Let's summarize them:

• [] - Primarily selects subsets of columns, but can select rows as well. Cannot simultaneously select rows and columns.
• .loc - selects subsets of rows and columns by label only
• .iloc - selects subsets of rows and columns by integer location only

I almost never use .at or .iat as they add no additional functionality and with just a small performance increase. I would discourage their use unless you have a very time-sensitive application. Regardless, we have their summary:

• .at selects a single scalar value in the DataFrame by label only
• .iat selects a single scalar value in the DataFrame by integer location only

In addition to selection by label and integer location, boolean selection also known as boolean indexing exists.

Examples explaining .loc, .iloc, boolean selection and .at and .iat are shown below

We will first focus on the differences between .loc and .iloc. Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each row. Let's take a look at a sample DataFrame:

df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
                   'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
                   'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
                   'height':[165, 70, 120, 80, 180, 172, 150],
                   'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
                   'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
                   },
                  index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])

All the words in bold are the labels. The labels, age, color, food, height, score and state are used for the columns. The other labels, Jane, Nick, Aaron, Penelope, Dean, Christina, Cornelia are used as labels for the rows. Collectively, these row labels are known as the index.

The primary ways to select particular rows in a DataFrame are with the .loc and .iloc indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.

.loc selects data only by labels

We will first talk about the .loc indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length(number of rows) of the DataFrame.

There are many different inputs you can use for .loc three out of them are

• A string
• A list of strings
• Slice notation using strings as the start and stop values

Selecting a single row with .loc with a string

To select a single row of data, place the index label inside of the brackets following .loc.

df.loc['Penelope']

This returns the row of data as a Series

age           4
color     white
food      Apple
height       80
score       3.3
state        AL
Name: Penelope, dtype: object

Selecting multiple rows with .loc with a list of strings

df.loc[['Cornelia', 'Jane', 'Dean']]

This returns a DataFrame with the rows in the order specified in the list:

Selecting multiple rows with .loc with slice notation

Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.

df.loc['Aaron':'Dean']

Complex slices can be taken in the same manner as Python lists.

.iloc selects data only by integer location

Let's now turn to .iloc. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.

There are many different inputs you can use for .iloc three out of them are

• An integer
• A list of integers
• Slice notation using integers as the start and stop values

Selecting a single row with .iloc with an integer

df.iloc[4]

This returns the 5th row (integer location 4) as a Series

age           32
color       gray
food      Cheese
height       180
score        1.8
state         AK
Name: Dean, dtype: object

Selecting multiple rows with .iloc with a list of integers

df.iloc[[2, -2]]

This returns a DataFrame of the third and second to last rows:

Selecting multiple rows with .iloc with slice notation

df.iloc[:5:3]

Simultaneous selection of rows and columns with .loc and .iloc

One excellent ability of both .loc/.iloc is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.

For example, we can select rows Jane, and Dean with just the columns height, score and state like this:

df.loc[['Jane', 'Dean'], 'height':]

This uses a list of labels for the rows and slice notation for the columns

We can naturally do similar operations with .iloc using only integers.

df.iloc[[1,4], 2]
Nick      Lamb
Dean    Cheese
Name: food, dtype: object

Simultaneous selection with labels and integer location

.ix was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.

For instance, if we want to select rows Nick and Cornelia along with columns 2 and 4, we could use .loc by converting the integers to labels with the following:

col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names] 

Or alternatively, convert the index labels to integers with the get_loc index method.

labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]

Boolean Selection

The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows where age is above 30 and return just the food and score columns we can do the following:

df.loc[df['age'] > 30, ['food', 'score']] 

You can replicate this with .iloc but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:

df.iloc[(df['age'] > 30).values, [2, 4]] 

Selecting all rows

It is possible to use .loc/.iloc for just column selection. You can select all the rows by using a colon like this:

df.loc[:, 'color':'score':2]

The indexing operator, [], can slice can select rows and columns too but not simultaneously.

Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.

df['food']

Jane          Steak
Nick           Lamb
Aaron         Mango
Penelope      Apple
Dean         Cheese
Christina     Melon
Cornelia      Beans
Name: food, dtype: object

Using a list selects multiple columns

df[['food', 'score']]

What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.

df['Penelope':'Christina'] # slice rows by label

df[2:6:2] # slice rows by integer location

The explicitness of .loc/.iloc for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.

df[3:5, 'color']
TypeError: unhashable type: 'slice'

Selection by .at and .iat

Selection with .at is nearly identical to .loc but it only selects a single 'cell' in your DataFrame. We usually refer to this cell as a scalar value. To use .at, pass it both a row and column label separated by a comma.

df.at['Christina', 'color']
'black'

Selection with .iat is nearly identical to .iloc but it only selects a single scalar value. You must pass it an integer for both the row and column locations

df.iat[2, 5]
'FL'

I'm surprised in a TypeScript thread no one gave valid TypeScript function with typing supported. Here's variation of @user8363 solution:

const isStringNumber = (value: string) => isNaN(Number(value)) === false;

function enumToArray<T extends {}>(givenEnum: T) {
  return (Object.keys(givenEnum).filter(isStringNumber) as (keyof T)[]).map(
    (key) => givenEnum[key]
  );
}

Your code can get messy fast when dealing with CSS3 transitions. I would recommend using a plugin such as jQuery Transit that handles the complexity of CSS3 animations/transitions.

Moreover, the plugin uses webkit-transform rather than webkit-transition, which allows for mobile devices to use hardware acceleration in order to give your web apps that native look and feel when the animations occur.

JS Fiddle Live Demo

Javascript:

$("#startTransition").on("click", function()
{

    if( $(".boxOne").is(":visible")) 
    {
        $(".boxOne").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxOne").hide(); });
        $(".boxTwo").css({ x: '100%' });
        $(".boxTwo").show().transition({ x: '0%', opacity: 1.0 });
        return;        
    }

    $(".boxTwo").transition({ x: '-100%', opacity: 0.1 }, function () { $(".boxTwo").hide(); });
    $(".boxOne").css({ x: '100%' });
    $(".boxOne").show().transition({ x: '0%', opacity: 1.0 });

});

Most of the hard work of getting cross-browser compatibility is done for you as well and it works like a charm on mobile devices.

For adding item in Spinner, you can do one thing, try to create an adapter and then add/remove items into the adapter, then you can easily bind that adapter to spinner by using setAdapter() method.

Here is an example:

spinner.setAdapter(adapter);
adapter.add(item1);
adapter.add(item2);
adapter.add(item3);
adapter.add(item4);
adapter.add(item5);
adapter.notifyDataSetChanged();
spinner.setAdapter(adapter);

vim's DirDiff plugin is another very useful tool for comparing directories.

vim -c "DirDiff dir1 dir2"

It not only lists which files are different between the directories, but also allows you to inspect/modify with vimdiff the files that are different.

Place them inside of the success: of the one it relies on.

$.ajax({
    url: 'http://www.xxxxxxxxxxxxx',
    data: {name: 'xxxxxx'},
    dataType: 'jsonp',
    success: function(data){

        // do stuff

        // call next ajax function
        $.ajax({ xxx });
    }
});

I had the same problem as deke. I forgot to include the most important script: angular.js :)

<script type="text/javascript" src="bower_components/angular/angular.min.js"></script>

when you have an existing form, that should now work with jquery - ajax/post now you could:

• hang onto the submit - event of your form
• prevent default functionality of submit

• do your own stuff

  $(function() {
      //hang on event of form with id=myform
      $("#myform").submit(function(e) {
  
          //prevent Default functionality
          e.preventDefault();
  
          //get the action-url of the form
          var actionurl = e.currentTarget.action;
  
          //do your own request an handle the results
          $.ajax({
                  url: actionurl,
                  type: 'post',
                  dataType: 'application/json',
                  data: $("#myform").serialize(),
                  success: function(data) {
                      ... do something with the data...
                  }
          });
  
      });
  
  });
  

Please note that, in order for the serialize() function to work in the example above, all form elements need to have their name attribute defined.

Example of the form:

<form id="myform" method="post" action="http://example.com/do_recieve_request">

<input type="text" size="20" value="default value" name="my_input_field">
..
.
</form>

@PtF - the data is submitted using POST in this sample, so this means you can access your data via

 $_POST['dataproperty1'] 

, where dataproperty1 is a "variable-name" in your json.

here sample syntax if you use CodeIgniter:

 $pdata = $this->input->post();
 $prop1 = $pdata['prop1'];
 $prop1 = $pdata['prop2'];

You probably redefined your "sum" function to be an integer data type. So it is rightly telling you that an integer is not something you can pass a range.

To fix this, restart your interpreter.

Python 2.7.3 (default, Apr 20 2012, 22:44:07) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> data1 = range(0, 1000, 3)
>>> data2 = range(0, 1000, 5)
>>> data3 = list(set(data1 + data2)) # makes new list without duplicates
>>> total = sum(data3) # calculate sum of data3 list's elements
>>> print total
233168

If you shadow the sum builtin, you can get the error you are seeing

>>> sum = 0
>>> total = sum(data3) # calculate sum of data3 list's elements
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

Also, note that sum will work fine on the set there is no need to convert it to a list

Documentation on UISwitch says:

[mySwitch setOn:NO]; 

In Interface Builder, select your switch and in the Attributes inspector you'll find State which can be set to on or off.

If you are using CORS middleware and you want to send withCredentials boolean true, you can configure CORS like this:

var cors = require('cors');    _x000D_
app.use(cors({credentials: true, origin: 'http://localhost:5000'}));

I like the solution from

@Eddie Loeffen's answer seems to be the most popular answer to this question, but it has some bad long term effects. If you review the documentation page for System.Net.ServicePointManager.SecurityProtocol here the remarks section implies that the negotiation phase should just address this (and forcing the protocol is bad practice because in the future, TLS 1.2 will be compromised as well). However, we wouldn't be looking for this answer if it did.

Researching, it appears that the ALPN negotiation protocol is required to get to TLS1.2 in the negotiation phase. We took that as our starting point and tried newer versions of the .Net framework to see where support starts. We found that .Net 4.5.2 does not support negotiation to TLS 1.2, but .Net 4.6 does.

So, even though forcing TLS1.2 will get the job done now, I recommend that you upgrade to .Net 4.6 instead. Since this is a PCI DSS issue for June 2016, the window is short, but the new framework is a better answer.

UPDATE: Working from the comments, I built this:

ServicePointManager.SecurityProtocol = 0;    
foreach (SecurityProtocolType protocol in SecurityProtocolType.GetValues(typeof(SecurityProtocolType)))
    {
        switch (protocol)
        {
            case SecurityProtocolType.Ssl3:
            case SecurityProtocolType.Tls:
            case SecurityProtocolType.Tls11:
                break;
            default:
                ServicePointManager.SecurityProtocol |= protocol;
            break;
        }
    }

In order to validate the concept, I or'd together SSL3 and TLS1.2 and ran the code targeting a server that supports only TLS 1.0 and TLS 1.2 (1.1 is disabled). With the or'd protocols, it seems to connect fine. If I change to SSL3 and TLS 1.1, that failed to connect. My validation uses HttpWebRequest from System.Net and just calls GetResponse(). For instance, I tried this and failed:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls11;
        request.GetResponse();

while this worked:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
        request.GetResponse();

This has an advantage over forcing TLS 1.2 in that, if the .Net framework is upgraded so that there are more entries in the Enum, they will be supported by the code as is. It has a disadvantage over just using .Net 4.6 in that 4.6 uses ALPN and should support new protocols if no restriction is specified.

Edit 4/29/2019 - Microsoft published this article last October. It has a pretty good synopsis of their recommendation of how this should be done in the various versions of .net framework.

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

There's a built in method to obtain a UIImage that is automatically rendered in template mode. This uses a view's tintColor to color the image:

let templateImage = originalImage.imageWithRenderingMode(UIImageRenderingModeAlwaysTemplate)
myImageView.image = templateImage
myImageView.tintColor = UIColor.orangeColor()

$files = glob($_SERVER["DOCUMENT_ROOT"]."/myFolder/*");

Use timer.scheduleAtFixedRate

In fixed-rate execution, each execution is scheduled relative to the scheduled execution time of the initial execution. If an execution is delayed for any reason (such as garbage collection or other background activity), two or more executions will occur in rapid succession to "catch up." In the long run, the frequency of execution will be exactly the reciprocal of the specified period (assuming the system clock underlying Object.wait(long) is accurate).

Fixed-rate execution is appropriate for recurring activities that are sensitive to absolute time, such as ringing a chime every hour on the hour, or running scheduled maintenance every day at a particular time. It is also appropriate for recurring activities where the total time to perform a fixed number of executions is important, such as a countdown timer that ticks once every second for ten seconds. Finally, fixed-rate execution is appropriate for scheduling multiple repeating timer tasks that must remain synchronized with respect to one another.

Parameters:

• task - task to be scheduled.
• delay - delay in milliseconds before task is to be executed.
• period - time in milliseconds between successive task executions.

Throws:

• IllegalArgumentException - if delay is negative, or delay + System.currentTimeMillis() is negative.
• IllegalStateException - if task was already scheduled or cancelled, timer was cancelled, or timer thread terminated.

for (int i = 0; i < a.length; i++) 
{
    for (int k = i+1; k < a.length; k++) 
    {
        if (a[i] != a[k]) 
         {
            System.out.println(a[i]+"not the same with"+a[k]+"\n");
        }
    }
}

This command worked for me:

adb shell pm clear packageName

Or, if you can use a DataGridView, you could just call Sort(column, direction):

namespace Sorter
{
    using System;
    using System.ComponentModel;
    using System.Windows.Forms;

    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
            this.dataGridView1.Rows.Add("Abc", 5);
            this.dataGridView1.Rows.Add("Def", 8);
            this.dataGridView1.Rows.Add("Ghi", 3);
            this.dataGridView1.Sort(this.dataGridView1.Columns[1], 
                                    ListSortDirection.Ascending);
        }
    }
}

Which would give you the desired result:

I get this error using gulp with rollup when I tried to use ES6 generators:

I may case the solution was to include babel-polyfill as bower component:

bower install babel-polyfill --save

and add it as dependency in index.html:

<script src="/bower_components/babel-polyfill/browser-polyfill.js"></script>

The child views in your list row should be considered selected whenever the parent row is selected, so you should be able to just set a normal state drawable/color-list on the views you want to change, no messy Java code necessary. See this SO post.

Specifically, you'd set the textColor of your textViews to an XML resource like this one:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:state_focused="true" android:drawable="@color/black" /> <!-- focused -->
    <item android:state_focused="true" android:state_pressed="true" android:drawable="@color/black" /> <!-- focused and pressed-->
    <item android:state_pressed="true" android:drawable="@color/green" /> <!-- pressed -->
    <item android:drawable="@color/black" /> <!-- default -->
</selector> 

try this. It will solve your problem.

 var lastDayOfMonth = DateTime.DaysInMonth(int.Parse(ddlyear.SelectedValue), int.Parse(ddlmonth.SelectedValue));
DateTime tLastDayMonth = Convert.ToDateTime(lastDayOfMonth.ToString() + "/" + ddlmonth.SelectedValue + "/" + ddlyear.SelectedValue);

It might be possible to delete the Zone Record entirely, then recreate it exactly as you want it. Perhaps this will force a full propagation. If I'm wrong, somebody tell me and I'll delete this suggestion. Also, I don't know how to save a Zone Record and recreate it using WHM or any other tool.

I do know that when I deleted a hosting account today and recreated it, the original Zone Record seemed to be propagated instantly to a DNS resolver up the line from my computer. That is good evidence it works.

Based on the method Bootstrap uses to set its Responsive breakpoints, the following function returns xs, sm, md, lg or xl based on the screen width:

console.log(breakpoint());

function breakpoint() {
    let breakpoints = {
        '(min-width: 1200px)': 'xl',
        '(min-width: 992px) and (max-width: 1199.98px)': 'lg',
        '(min-width: 768px) and (max-width: 991.98px)': 'md',
        '(min-width: 576px) and (max-width: 767.98px)': 'sm',
        '(max-width: 575.98px)': 'xs',
    }

    for (let media in breakpoints) {
        if (window.matchMedia(media).matches) {
            return breakpoints[media];
        }
    }

    return null;
}

public class MyActivity extends AppCompatActivity implements View.OnClickListener {

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

        Button button = findViewById(R.id.button);
        Button button2 = findViewById(R.id.button2);

        button.setOnClickListener(this);
        button2.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {

        int id = view.getId();

        switch (id) {

            case R.id.button:

                  // Write your code here first button

                break;

             case R.id.button2:

                  // Write your code here for second button

                break;

        }

    }

}

one more possible solution:

function toFix(i){
 var str='';
 do{
   let a = i%10;
   i=Math.trunc(i/10);
   str = a+str;
 }while(i>0)
 return str;
}

You can try this

var scroll=$('#scroll');
scroll.animate({scrollTop: scroll.prop("scrollHeight")});

Adding a parameter to url fool browser to load a new page. I wrote a fuction for that purpose:

function forceReload(){
    
    function setUrlParams(url, key, value) {
        url = url.split('?');
        usp = new URLSearchParams(url[1]);
        usp.set(key, value);
        url[1] = usp.toString();
        return url.join('?');
    }
    
    window.location.href =setUrlParams(window.location.href,'_t',Date.now());
}

And you just need to call it:

forceReload();

In my case it was the security constraints defined in web.xml. Make sure they have the same roles you use in your tomcat-users.xml file.

For example, this is one of the out-of-the-box tags and will work with the standard tomcat-users.xml.

 <security-constraint>
    <web-resource-collection>
      <web-resource-name>HTML Manager interface (for humans)</web-resource-name>
      <url-pattern>/html/*</url-pattern>
    </web-resource-collection>
    <auth-constraint>
       <role-name>manager-gui</role-name>
    </auth-constraint>
  </security-constraint>

In my case an admin had used a different role-name which prevented me from accessing the manager.

window.localStorage.clear(); //try this to clear all local storage

If you take a look at the bootstraps fade class used with the modal window you will find, that all it does, is to set the opacity value to 0 and adds a transition for the opacity rule.

Whenever you launch a modal the in class is added and will change the opacity to a value of 1.

Knowing that you can easily build your own fade-scale class.

Here is an example.

@import url("https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css");_x000D_
_x000D_
.fade-scale {_x000D_

  opacity: 0;_x000D_
  -webkit-transition: all .25s linear;_x000D_
  -o-transition: all .25s linear;_x000D_
  transition: all .25s linear;_x000D_
}_x000D_
_x000D_
.fade-scale.in {_x000D_
  opacity: 1;_x000D_

-- UPDATE --

This answer is getting more up votes lately so i figured i add an update to show how easy it is to customize the BS modal in and out animations with the help of the great Animate.css library by
Daniel Eden.

All that needs to be done is to include the stylesheet to your <head></head> section. Now you simply need to add the animated class, plus one of the entrance classes of the library to the modal element.

<div class="modal animated fadeIn" id="myModal" tabindex="-1" role="dialog" ...>
  ...
</div>

But there is also a way to add an out animation to the modal window and since the library has a bunch of cool animations that will make an element disappear, why not use them. :)

To use them you will need to toggle the classes on the modal element, so it is actually better to call the modal window via JavaScript, which is described here.

You will also need to listen for some of the modal events to know when it's time to add or remove the classes from the modal element. The events being fired are described here.

To trigger a custom out animation you can't use the data-dismiss="modal" attribute on a button inside the modal window that's suppose to close the modal. You can simply add your own attribute like data-custom-dismiss="modal" and use that to call the $('selector').modal.('hide') method on it.

Here is an example that shows all the different possibilities.

the DD-MM-YYYY is just one of the formats. The format of the jquery plugin, is based on this list: http://docs.oracle.com/javase/7/docs/api/java/text/SimpleDateFormat.html

Tested following code in chrome console:

test = new Date()
test.format('d-M-Y')
"15-Dec-2014"

object[,] valueArray = (object[,])excelRange.get_Value(XlRangeValueDataType.xlRangeValueDefault);

//Get the column names
for (int k = 0; k < valueArray.GetLength(1); )
{
    //add columns to the data table.
    dt.Columns.Add((string)valueArray[1,++k]);
}

//Load data into data table
object[] singleDValue = new object[valueArray.GetLength(1)];
//value array first row contains column names. so loop starts from 1 instead of 0
for (int i = 1; i < valueArray.GetLength(0); i++)
{
    Console.WriteLine(valueArray.GetLength(0) + ":" + valueArray.GetLength(1));
    for (int k = 0; k < valueArray.GetLength(1); )
    {
        singleDValue[k] = valueArray[i+1, ++k];
    }
    dt.LoadDataRow(singleDValue, System.Data.LoadOption.PreserveChanges);
}

What is more logical then testing the TYPE of the result variable before processing? It is either of type 'boolean' or 'resource'. When you use a boolean for parameter with mysqli_num_rows, a warning will be generated because the function expects a resource.

$result = mysqli_query($dbs, $sql);

if(gettype($result)=='boolean'){ // test for boolean
    if($result){  // returned TRUE, e.g. in case of a DELETE sql  
        echo "SQL succeeded"; 
    } else { // returned FALSE
        echo "Error: " . mysqli_error($dbs);
    } 
} else { // must be a resource
    if(mysqli_num_rows($result)){

       // process the data    

    }
    mysqli_free_result($result);  
 }

s3admin is an opensource app (UI) that lets you browse buckets, calculate total size, show largest/smallest files. It's tailored for having a quick overview of your Buckets and their usage.

I think you must firstly add a .wav file to Resources. For example you have sound file named Sound.wav. After you added the Sound.wav file to Resources, you can use this code:

System.Media.SoundPlayer player = new System.Media.SoundPlayer(Properties.Resources.Sound);
player.Play();

This is another way to play sound.

Here is the a quick solution for multiple checkbox validation using jquery validation plugin:

jQuery.validator.addMethod('atLeastOneChecked', function(value, element) {
  return ($('.cbgroup input:checked').length > 0);
});

$('#subscribeForm').validate({
  rules: {
    list0: { atLeastOneChecked: true }
  },
  messages: {
    list0: { 'Please check at least one option' }
  }
});

$('.cbgroup input').click(function() {
  $('#list0').valid();
});

In C/C++ you have header files (*.H). There you declare your functions/classes. So for example you will have to #include "second.h" to your main.cpp file.

In second.h you just declare like this void yourFunction(); In second.cpp you implement it like

void yourFunction() { 
   doSomethng(); 
}

Don't forget to #include "second.h" also in the beginning of second.cpp

Hope this helps:)

From the documentation I found this

JObject o = new JObject(
   new JProperty("Name", "John Smith"),
   new JProperty("BirthDate", new DateTime(1983, 3, 20))
);

JsonSerializer serializer = new JsonSerializer();
Person p = (Person)serializer.Deserialize(new JTokenReader(o), typeof(Person));

Console.WriteLine(p.Name);

The class definition for Person should be compatible to the following:

class Person {
    public string Name { get; internal set; }
    public DateTime BirthDate { get; internal set; }
}

Edit

If you are using a recent version of JSON.net and don't need custom serialization, please see TienDo's answer above (or below if you upvote me :P ), which is more concise.

There is a new spec called the Native File System API that allows you to do this properly like this:

const result = await window.chooseFileSystemEntries({ type: "save-file" });

There is a demo here, but I believe it is using an origin trial so it may not work in your own website unless you sign up or enable a config flag, and it obviously only works in Chrome. If you're making an Electron app this might be an option though.

TL;DR

useEffect(yourCallback, []) - will trigger the callback only after the first render.

Detailed explanation

useEffect runs by default after every render of the component (thus causing an effect).

When placing useEffect in your component you tell React you want to run the callback as an effect. React will run the effect after rendering and after performing the DOM updates.

If you pass only a callback - the callback will run after each render.

If passing a second argument (array), React will run the callback after the first render and every time one of the elements in the array is changed. for example when placing useEffect(() => console.log('hello'), [someVar, someOtherVar]) - the callback will run after the first render and after any render that one of someVar or someOtherVar are changed.

By passing the second argument an empty array, React will compare after each render the array and will see nothing was changed, thus calling the callback only after the first render.

To find where Anaconda was installed I used the "where" command on the command line in Windows.

C:\>where anaconda

which for me returned:

C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\Scripts\anaconda.exe

Which allowed me to find the Anaconda Python interpreter at

C:\Users\User-Name\AppData\Local\Continuum\Anaconda2\python.exe

Yes, you can merge them using HTML. When I create tables in .md files from Github, I always like to use HTML code instead of markdown.

Github Flavored Markdown supports basic HTML in .md file. So this would be the answer:

Markdown mixed with HTML:

| Tables        | Are           | Cool  |
| ------------- |:-------------:| -----:|
| col 3 is      | right-aligned | $1600 |
| col 2 is      | centered      |   $12 |
| zebra stripes | are neat      |    $1 |
| <ul><li>item1</li><li>item2</li></ul>| See the list | from the first column|

Or pure HTML:

<table>
  <tbody>
    <tr>
      <th>Tables</th>
      <th align="center">Are</th>
      <th align="right">Cool</th>
    </tr>
    <tr>
      <td>col 3 is</td>
      <td align="center">right-aligned</td>
      <td align="right">$1600</td>
    </tr>
    <tr>
      <td>col 2 is</td>
      <td align="center">centered</td>
      <td align="right">$12</td>
    </tr>
    <tr>
      <td>zebra stripes</td>
      <td align="center">are neat</td>
      <td align="right">$1</td>
    </tr>
    <tr>
      <td>
        <ul>
          <li>item1</li>
          <li>item2</li>
        </ul>
      </td>
      <td align="center">See the list</td>
      <td align="right">from the first column</td>
    </tr>
  </tbody>
</table>

If you've set the correct code signing certificate under Build Settings->Code Signing, then make sure you are also using the correct provisioning profile for Debug/Release mode as well.

I was having this issue because I was using an Ad-Hoc provisioning profile for both Debug/Release modes, which doesn't allow for a development profile to be used when doing a debug build.

Just to add to what's already here, use the following:

background: -moz-linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
background: -webkit-linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
background: linear-gradient(rgba(0,0,0,.7),rgba(0,0,0,.7));
filter: unquote("progid:DXImageTransform.Microsoft.gradient( startColorstr='#b3000000', endColorstr='#b3000000',GradientType=0 )");

...for cross-browser support of a 70% linear-gradient overlay. To brighten the image, you can change all those 0,0,0's into 255,255,255's. If 70% is a bit much, go ahead and change the .7. And, for future reference check out this: http://www.colorzilla.com/gradient-editor/

When you log in to your developer account, you can find a link at the bottom of the download section for Xcode that says "Looking for an older version of Xcode?". In there you can find download links to older versions of Xcode and other developer tools

An SMS Push is a message to tell the terminal to initiate the session. This happens because you can't initiate an IP session simply because you don't know the IP Adress of the mobile terminal. Mostly used to send a few lines of data to end recipient, to the effect of sending information, or reminding of events.

WAP Push is an SMS within the header of which is included a link to a WAP address. On receiving a WAP Push, the compatible mobile handset automatically gives the user the option to access the WAP content on his handset. The WAP Push directs the end-user to a WAP address where content is stored ready for viewing or downloading onto the handset. This wap address may be a page or a WAP site.

The user may “take action” by using a developer-defined soft-key to immediately activate an application to accomplish a specific task, such as downloading a picture, making a purchase, or responding to a marketing offer.

You need to set option CURLOPT_PROXYTYPE to CURLPROXY_SOCKS5_HOSTNAME, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7:

curl_setopt($ch, CURLOPT_PROXYTYPE, 7);

command to remove cordova and ionic

sudo npm uninstall -g ionic

Reason

The declaration of x is inside foo but the x=5 initialization takes place outside of foo!

What we need to understand here is that

static int x = 5;

is not the same as

static int x;
x = 5;

Other answers have used the important words here, scope and lifetime, and pointed out that the scope of x is from the point of its declaration in the function foo to the end of the function foo. For example I checked by moving the declaration to the end of the function, and that makes x undeclared at the x++; statement.

So the static int x (scope) part of the statement actually applies where you read it, somewhere INSIDE the function and only from there onwards, not above it inside the function.

However the x = 5 (lifetime) part of the statement is initialization of the variable and happening OUTSIDE of the function as part of the program loading. Variable x is born with a value of 5 when the program loads.

I read this in one of the comments: "Also, this doesn't address the really confusing part, which is the fact that the initializer is skipped on subsequent calls." It is skipped on all calls. Initialization of the variable is outside of the function code proper.

The value of 5 is theoretically set regardless of whether or not foo is called at all, although a compiler might optimize the function away if you don't call it anywhere. The value of 5 should be in the variable before foo is ever called.

Inside of foo, the statement static int x = 5; is unlikely to be generating any code at all.

I found the address x uses when I put a function foo into a program of mine, and then (correctly) guessed that the same location would be used if I ran the program again. The partial screen capture below shows that x has the value 5 even before the first call to foo.

You sure can. Create an HTML page with the form in it that will contain the necessary components from the login.aspx page (i.e. username, etc), and make sure they have the same IDs. For you action, make sure it's a post.

You might have to do some code on the login.aspx page in the Page_Load function to read the form (in the Request.Form object) and call the appropriate functions to log the user in, but other than that, you should have access to the form, and can do what you want with it.

You can use the folowing to get the full path to your program like this:

Environment.CurrentDirectory

Navigate to /tomcat-root/conf folder. Within you will find the server.xml file.

Open the server.xml in your preferred editor. Search the below similar statement (not exactly same as below will differ)

    <Connector port="8080" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Going to give the port number to 9090

     <Connector port="9090" protocol="HTTP/1.1" 
           connectionTimeout="20000" 
           redirectPort="8443" />

Save the file and restart the server. Now the tomcat will listen at port 9090

function groupBy(data, property) {
  return data.reduce((acc, obj) => {
    const key = obj[property];
    if (!acc[key]) {
      acc[key] = [];
    }
    acc[key].push(obj);
    return acc;
  }, {});
}
groupBy(people, 'age');

I use this feature often enough that I add a custom button to the command bar.

1. Click on the Add or Remove Buttons -> Customize
2. Click on the Commands tab
3. Click Add Command...
4. Select Edit (or Edit|Advanced for newer VS versions) from the list
5. Find Toggle Word Wrap and drag it onto your bar

I tried this is working

ALTER DATABASE dbName SET MULTI_USER WITH ROLLBACK IMMEDIATE

One more point to add on to this thread.

If you add an underscore in your .css file name, then it wouldn't work.

I was facing the same issues recently and found a solution which worked for me and reduced the memory consumption level upto a great extent.

Solution:

First of all find the application which is causing heavy memory usage.

You can find this in the Details section of the Task Manager.

Next.

1. Open the IIS manager.
2. Click on Application Pools. You'll find many application pools which your system is using.
3. Now from the task manager you've found which application is causing the heavy memory consumption. There would be multiple options for that and you need to select the one which is having '1' in it's Application column of your web application.
4. When you click on the application pool on the right hand side you'll see an option Advance settings under Edit Application pools. Go to Advanced Settings. 5.Now under General category set the Enable 32-bit Applications to True
5. Restart the IIS server or you can see the consumption goes down in performance section of your Task Manager.

If this solution works for you please add a comment so that I can know.

As mentioned by @SalCelli, chrome://restart works. However, this relaunches all the tabs.

Another method is to launch in incognito mode as suggested by CEGRD

However, if you could not like to restart & use incognito, on Chrome 86 (Mac), I found that the answer provided by @opsb & Mike only works with the below additional steps.

1. Enter the wrong username in the url without the resources

   eg: if the url is http://mywebsite.com/resources/, it will not work if I enter http://[email protected]/resources/, but will work if I enter only http://[email protected]/

   1. it clears the Basic Auth credentials
   2. prompt for the credentials again

2. However, entering the valid credentials will not work, as in the background, chrome still send the wrong user as part of the url, even though the url appears right in the address bar When prompted for credentials you would need to Cancel, and click the address bar and reload the page from pressing enter. Now enter the correct password

This is a unity only answer:

Check this ready-to-use method: Give in a range & count of number you want to get.

public static int[] getUniqueRandomArray(int min, int max, int count) {
    int[] result = new int[count];
    List<int> numbersInOrder = new List<int>();
    for (var x = min; x < max; x++) {
        numbersInOrder.Add(x);
    }
    for (var x = 0; x < count; x++) {
        var randomIndex = UnityEngine.Random.Range(0, numbersInOrder.Count);
        result[x] = numbersInOrder[randomIndex];
        numbersInOrder.RemoveAt(randomIndex);
    }

    return result;
}

A very portable version (even to legacy bourne shell):

if [ "$varA" = 1 -a \( "$varB" = "t1" -o "$varB" = "t2" \) ]
then    do-something
fi

This has the additional quality of running only one subprocess at most (which is the process [), whatever the shell flavor.

Replace = with -eq if variables contain numeric values, e.g.

• 3 -eq 03 is true, but
• 3 = 03 is false. (string comparison)

I did something similar with this construct

$('li').each(function(){
  if(this.id){
    this.id = this.id+"something";
  }
});

Removed and added back in the table using Scaffold-DbContext and the error went away

You can retrieve the series through slicing your dataframe using one of these two methods:

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.iloc.html http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.loc.html

import pandas as pd
import numpy as np
df = pd.DataFrame(data=np.random.randn(1,8))

series1=df.iloc[0,:]
type(series1)
pandas.core.series.Series

When loading the Properties from a Class in the package com.al.common.email.templates you can use

Properties prop = new Properties();
InputStream in = getClass().getResourceAsStream("foo.properties");
prop.load(in);
in.close();

(Add all the necessary exception handling).

If your class is not in that package, you need to aquire the InputStream slightly differently:

InputStream in = 
 getClass().getResourceAsStream("/com/al/common/email/templates/foo.properties");

Relative paths (those without a leading '/') in getResource()/getResourceAsStream() mean that the resource will be searched relative to the directory which represents the package the class is in.

Using java.lang.String.class.getResource("foo.txt") would search for the (inexistent) file /java/lang/String/foo.txt on the classpath.

Using an absolute path (one that starts with '/') means that the current package is ignored.

Declare the array size will solve your problem

 String[] title = {
            "Abundance",
            "Anxiety",
            "Bruxism",
            "Discipline",
            "Drug Addiction"
        };
    String urlbase = "http://www.somewhere.com/data/";
    String imgSel = "/logo.png";
    String[] mStrings = new String[title.length];

    for(int i=0;i<title.length;i++) {
        mStrings[i] = urlbase + title[i].toLowerCase() + imgSel;

        System.out.println(mStrings[i]);
    }

Simplest Solution With Simple Date Format: SimpleDateFormat("ZZZZZ"):

 Calendar calendar = Calendar.getInstance(TimeZone.getTimeZone("GMT"),
                Locale.getDefault());
        Date currentLocalTime = calendar.getTime();

        DateFormat date = new SimpleDateFormat("ZZZZZ",Locale.getDefault());
        String localTime = date.format(currentLocalTime);
        System.out.println(localTime+ "  TimeZone   " );

==> Output is : +05:30

Uhmm.. these seem too complex to me. May I propose

def listTestD = (0 to 3).toList

or

def listTestE = for (i <- (0 to 3).toList) yield i

To summarize with a complete solution...

There are 2 options:

1. Use NMAKE from the Developer Command Prompt for Visual Studio

The shortcut exists in your Start Menu. Look inside the makefile to see if there are any 'setup' actions. Actions appear as the first word before a colon. Typically, all good makefiles have an "all" action so you can type: NMAKE all

2. Create a Solution and Project Files for each binary.

Most well designed open source solutions provide a makefile with a setup action to generate Visual Studio Project Files for you so look for those first in your Makefile.

Otherwise you need to drag and drop each file or group of files and folders into each New Project you create within Visual Studio.

Hope this helps.

This changed a bit in babel v6.

From the docs:

The polyfill will emulate a full ES6 environment. This polyfill is automatically loaded when using babel-node.

Installation:
$ npm install babel-polyfill

Usage in Node / Browserify / Webpack:
To include the polyfill you need to require it at the top of the entry point to your application.
require("babel-polyfill");

Usage in Browser:
Available from the dist/polyfill.js file within a babel-polyfill npm release. This needs to be included before all your compiled Babel code. You can either prepend it to your compiled code or include it in a <script> before it.

NOTE: Do not require this via browserify etc, use babel-polyfill.

Rohit's answer seems correct. However, be aware that AndroidStudio's "Instant Run" depends on not having static Context attributes in your code, as far as I know.

Call .get() at the very end to turn the resulting jQuery object into a true array.

$("#merge_button").click(function(event){
    event.preventDefault();
    var searchIDs = $("#find-table input:checkbox:checked").map(function(){
      return $(this).val();
    }).get(); // <----
    console.log(searchIDs);
});

Per the documentation:

As the return value is a jQuery object, which contains an array, it's very common to call .get() on the result to work with a basic array.

There is a switch statement but I can never seem to get it to work the way I think it should. Since you have not provided an example I will make one using a factor variable:

 dft <-data.frame(x = sample(letters[1:8], 20, replace=TRUE))
 levels(dft$x)
[1] "a" "b" "c" "d" "e" "f" "g" "h"

If you specify the categories you want in an order appropriate to the reassignment you can use the factor or numeric variables as an index:

c("abc", "abc", "abc", "def", "def", "def", "g", "h")[dft$x]
 [1] "def" "h"   "g"   "def" "def" "abc" "h"   "h"   "def" "abc" "abc" "abc" "h"   "h"   "abc"
[16] "def" "abc" "abc" "def" "def"

dft$y <- c("abc", "abc", "abc", "def", "def", "def", "g", "h")[dft$x] str(dft)
'data.frame':   20 obs. of  2 variables:
 $ x: Factor w/ 8 levels "a","b","c","d",..: 4 8 7 4 6 1 8 8 5 2 ...
 $ y: chr  "def" "h" "g" "def" ...

I later learned that there really are two different switch functions. It's not generic function but you should think about it as either switch.numeric or switch.character. If your first argument is an R 'factor', you get switch.numeric behavior, which is likely to cause problems, since most people see factors displayed as character and make the incorrect assumption that all functions will process them as such.

Using CSS you can set a style for that specific button using the id (#) selector:

#search {
    width: 20em;  height: 2em;
}

or if you want all submit buttons to be a particular size:

input[type=submit] {
    width: 20em;  height: 2em;
}

or if you want certain classes of button to be a particular style you can use CSS classes:

<input type="submit" id="search" value="Search" class="search" />

and

input.search {
    width: 20em;  height: 2em;
}

I use ems as the measurement unit because they tend to scale better.

As @impulsgraw wrote. You need to check for undefined after the pipes:

<div ng-show="foo || undefined">
    Show this if foo is defined!
</div>
<div ng-show="boo || !undefined">
    Show this if boo is undefined!
</div>

A pure RESTful API should use the underlying protocol standard features:

1. For HTTP, the RESTful API should comply with existing HTTP standard headers. Adding a new HTTP header violates the REST principles. Do not re-invent the wheel, use all the standard features in HTTP/1.1 standards - including status response codes, headers, and so on. RESTFul web services should leverage and rely upon the HTTP standards.

2. RESTful services MUST be STATELESS. Any tricks, such as token based authentication that attempts to remember the state of previous REST requests on the server violates the REST principles. Again, this is a MUST; that is, if you web server saves any request/response context related information on the server in attempt to establish any sort of session on the server, then your web service is NOT Stateless. And if it is NOT stateless it is NOT RESTFul.

Bottom-line: For authentication/authorization purposes you should use HTTP standard authorization header. That is, you should add the HTTP authorization / authentication header in each subsequent request that needs to be authenticated. The REST API should follow the HTTP Authentication Scheme standards.The specifics of how this header should be formatted are defined in the RFC 2616 HTTP 1.1 standards – section 14.8 Authorization of RFC 2616, and in the RFC 2617 HTTP Authentication: Basic and Digest Access Authentication.

I have developed a RESTful service for the Cisco Prime Performance Manager application. Search Google for the REST API document that I wrote for that application for more details about RESTFul API compliance here. In that implementation, I have chosen to use HTTP "Basic" Authorization scheme. - check out version 1.5 or above of that REST API document, and search for authorization in the document.

The best solution to your problem is probably to first export your dataframe to HTML and then convert it using an HTML-to-image tool. The final appearance could be tweaked via CSS.

Popular options for HTML-to-image rendering include:

• WeasyPrint
• wkhtmltopdf/wkhtmltoimage

Let us assume we have a dataframe named df. We can generate one with the following code:

import string
import numpy as np
import pandas as pd


np.random.seed(0)  # just to get reproducible results from `np.random`
rows, cols = 5, 10
labels = list(string.ascii_uppercase[:cols])
df = pd.DataFrame(np.random.randint(0, 100, size=(5, 10)), columns=labels)
print(df)
#     A   B   C   D   E   F   G   H   I   J
# 0  44  47  64  67  67   9  83  21  36  87
# 1  70  88  88  12  58  65  39  87  46  88
# 2  81  37  25  77  72   9  20  80  69  79
# 3  47  64  82  99  88  49  29  19  19  14
# 4  39  32  65   9  57  32  31  74  23  35

Using WeasyPrint

This approach uses a pip-installable package, which will allow you to do everything using the Python ecosystem. One shortcoming of weasyprint is that it does not seem to provide a way of adapting the image size to its content. Anyway, removing some background from an image is relatively easy in Python / PIL, and it is implemented in the trim() function below (adapted from here). One also would need to make sure that the image will be large enough, and this can be done with CSS's @page size property.

The code follows:

import weasyprint as wsp
import PIL as pil


def trim(source_filepath, target_filepath=None, background=None):
    if not target_filepath:
        target_filepath = source_filepath
    img = pil.Image.open(source_filepath)
    if background is None:
        background = img.getpixel((0, 0))
    border = pil.Image.new(img.mode, img.size, background)
    diff = pil.ImageChops.difference(img, border)
    bbox = diff.getbbox()
    img = img.crop(bbox) if bbox else img
    img.save(target_filepath)


img_filepath = 'table1.png'
css = wsp.CSS(string='''
@page { size: 2048px 2048px; padding: 0px; margin: 0px; }
table, td, tr, th { border: 1px solid black; }
td, th { padding: 4px 8px; }
''')
html = wsp.HTML(string=df.to_html())
html.write_png(img_filepath, stylesheets=[css])
trim(img_filepath)

Using wkhtmltopdf/wkhtmltoimage

This approach uses an external open source tool and this needs to be installed prior to the generation of the image. There is also a Python package, pdfkit, that serves as a front-end to it (it does not waive you from installing the core software yourself), but I will not use it.

wkhtmltoimage can be simply called using subprocess (or any other similar means of running an external program in Python). One would also need to output to disk the HTML file.

The code follows:

import subprocess


df.to_html('table2.html')
subprocess.call(
    'wkhtmltoimage -f png --width 0 table2.html table2.png', shell=True)

and its aspect could be further tweaked with CSS similarly to the other approach.

The RestTemplate getForObject() method does not support setting headers. The solution is to use the exchange() method.

So instead of restTemplate.getForObject(url, String.class, param) (which has no headers), use

HttpHeaders headers = new HttpHeaders();
headers.set("Header", "value");
headers.set("Other-Header", "othervalue");
...

HttpEntity entity = new HttpEntity(headers);

ResponseEntity<String> response = restTemplate.exchange(
    url, HttpMethod.GET, entity, String.class, param);

Finally, use response.getBody() to get your result.

This question is similar to this question.

Background

You can use the base64 CLI tool to generate the base64 encoded version of your username + password like this:

$ echo -n "joeuser:secretpass" | base64
am9ldXNlcjpzZWNyZXRwYXNz

-or-

$ base64 <<<"joeuser:secretpass"
am9ldXNlcjpzZWNyZXRwYXNzCg==

Base64 is reversible so you can also decode it to confirm like this:

$ echo -n "joeuser:secretpass" | base64 | base64 -D
joeuser:secretpass

-or-

$ base64 <<<"joeuser:secretpass" | base64 -D
joeuser:secretpass

NOTE: username = joeuser, password = secretpass

Example #1 - using -H

You can put this together into curl like this:

$ curl -H "Authorization: Basic $(base64 <<<"joeuser:secretpass")" http://example.com

Example #2 - using -u

Most will likely agree that if you're going to bother doing this, then you might as well just use curl's -u option.

$ curl --help |grep -- "--user "
 -u, --user USER[:PASSWORD]  Server user and password

For example:

$ curl -u someuser:secretpass http://example.com

But you can do this in a semi-safer manner if you keep your credentials in a encrypted vault service such as LastPass or Pass.

For example, here I'm using the LastPass' CLI tool, lpass, to retrieve my credentials:

$ curl -u $(lpass show --username example.com):$(lpass show --password example.com) \

Example #3 - using curl config

There's an even safer way to hand your credentials off to curl though. This method makes use of the -K switch.

$ curl -X GET -K \
    <(cat <<<"user = \"$(lpass show --username example.com):$(lpass show --password example.com)\"") \
    http://example.com

When used, your details remain hidden, since they're passed to curl via a temporary file descriptor, for example:

+ curl -skK /dev/fd/63 -XGET -H 'Content-Type: application/json' https://es-data-01a.example.com:9200/_cat/health
++ cat
+++ lpass show --username example.com
+++ lpass show --password example.com

NOTE: Above I'm communicating with one of our Elasticsearch nodes, inquiring about the cluster's health.

This method is dynamically creating a file with the contents user = "<username>:<password>" and giving that to curl.

HTTP Basic Authorization

The methods shown above are facilitating a feature known as Basic Authorization that's part of the HTTP standard.

When the user agent wants to send authentication credentials to the server, it may use the Authorization field.

The Authorization field is constructed as follows:

1. The username and password are combined with a single colon (:). This means that the username itself cannot contain a colon.
2. The resulting string is encoded into an octet sequence. The character set to use for this encoding is by default unspecified, as long as it is compatible with US-ASCII, but the server may suggest use of UTF-8 by sending the charset parameter.
3. The resulting string is encoded using a variant of Base64.
4. The authorization method and a space (e.g. "Basic ") is then prepended to the encoded string.

For example, if the browser uses Aladdin as the username and OpenSesame as the password, then the field's value is the base64-encoding of Aladdin:OpenSesame, or QWxhZGRpbjpPcGVuU2VzYW1l. Then the Authorization header will appear as:

Authorization: Basic QWxhZGRpbjpPcGVuU2VzYW1l

Source: Basic access authentication

Manual cleanup:

You can KILL the processid.

mysql> show full processlist;

mysql> kill 1193777;

But:

• the php application might report errors (or the webserver, check the error logs)
• don't fix what is not broken - if you're not short on connections, just leave them be.

Automatic cleaner service ;)

Or you configure your mysql-server by setting a shorter timeout on wait_timeout and interactive_timeout

mysql> show variables like "%timeout%";
+--------------------------+-------+
| Variable_name            | Value |
+--------------------------+-------+
| connect_timeout          | 5     |
| delayed_insert_timeout   | 300   |
| innodb_lock_wait_timeout | 50    |
| interactive_timeout      | 28800 |
| net_read_timeout         | 30    |
| net_write_timeout        | 60    |
| slave_net_timeout        | 3600  |
| table_lock_wait_timeout  | 50    |
| wait_timeout             | 28800 |
+--------------------------+-------+
9 rows in set (0.00 sec)

Set with:

set global wait_timeout=3;
set global interactive_timeout=3;

(and also set in your configuration file, for when your server restarts)

But you're treating the symptoms instead of the underlying cause - why are the connections open? If the PHP script finished, shouldn't they close? Make sure your webserver is not using connection pooling...

You can also try this in plain javascript

"1234".slice(0,-1)

the negative second parameter is an offset from the last character, so you can use -2 to remove last 2 characters etc

Two issues jump out:

1. Your getData never returns anything, so its promise (async functions always return a promise) will resolve with undefined when it resolves

2. The error message clearly shows you're trying to directly render the promise getData returns, rather than waiting for it to resolve and then rendering the resolution

Addressing #1: getData should return the result of calling json:

async getData(){
   const res = await axios('/data');
   return await res.json();
}

Addressig #2: We'd have to see more of your code, but fundamentally, you can't do

<SomeElement>{getData()}</SomeElement>

...because that doesn't wait for the resolution. You'd need instead to use getData to set state:

this.getData().then(data => this.setState({data}))
              .catch(err => { /*...handle the error...*/});

...and use that state when rendering:

<SomeElement>{this.state.data}</SomeElement>

Update: Now that you've shown us your code, you'd need to do something like this:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            this.getData().then(data => this.setState({data}))
                          .catch(err => { /*...handle the error...*/});
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

Futher update: You've indicated a preference for using await in componentDidMount rather than then and catch. You'd do that by nesting an async IIFE function within it and ensuring that function can't throw. (componentDidMount itself can't be async, nothing will consume that promise.) E.g.:

class App extends React.Component{
    async getData() {
        const res = await axios('/data');
        return await res.json(); // (Or whatever)
    }
    constructor(...args) {
        super(...args);
        this.state = {data: null};
    }
    componentDidMount() {
        if (!this.state.data) {
            (async () => {
                try {
                    this.setState({data: await this.getData()});
                } catch (e) {
                    //...handle the error...
                }
            })();
        }
    }
    render() {
        return (
            <div>
                {this.state.data ? <em>Loading...</em> : this.state.data}
            </div>
        );
    }
}

One way is to use the Extended State. This asks the underlying OS to maximize the JFrame.

setExtendedState(getExtendedState() | JFrame.MAXIMIZED_BOTH);

Other approach would be to manually maximize the screen for you requirement.

Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(100, 100, (int) dim.getWidth(), (int) dim.getHeight());
setLocationRelativeTo(null);

But this has pitfalls in Ubuntu OS. The work around I found was this.

if (SystemHelper.isUnix()) {
    getContentPane().setPreferredSize(
    Toolkit.getDefaultToolkit().getScreenSize());
    pack();
    setResizable(false);
    show();

    SwingUtilities.invokeLater(new Runnable() {
        public void run() {
            Point p = new Point(0, 0);
            SwingUtilities.convertPointToScreen(p, getContentPane());
            Point l = getLocation();
            l.x -= p.x;
            l.y -= p.y;
            setLocation(p);
        }
    });
}

Dimension dim = Toolkit.getDefaultToolkit().getScreenSize();
setBounds(100, 100, (int) dim.getWidth(), (int) dim.getHeight());
setLocationRelativeTo(null);

In Fedora the above problem is not present. But there are complications involved with Gnome or KDE. So better be careful. Hope this helps.
