Instructions here are a little complicated so I'm going to offer something more straightforward:

1. git reset HEAD --hard Abandon all changes to the current branch

2. ... Perform intermediary work as necessary

3. git stash pop Re-pop the stash again at a later date when you're ready

Here is the jsFiddle

#backdrop{
    border: 2px solid red;
    width: 400px;
    height: 200px;
    position: absolute;
}

#curtain {
    border: 1px solid blue;
    width: 400px;
    height: 200px;
    position: absolute;
}

Use Z-index to move the one you want on top.

A slight edit on an example provided in http://matplotlib.org/users/shell.html:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.set_title('click on points')

line, = ax.plot(np.random.rand(100), '-', picker=5)  # 5 points tolerance


def onpick(event):
    thisline = event.artist
    xdata = thisline.get_xdata()
    ydata = thisline.get_ydata()
    ind = event.ind
    print('onpick points:', *zip(xdata[ind], ydata[ind]))


fig.canvas.mpl_connect('pick_event', onpick)

plt.show()

This plots a straight line plot, as Sohaib was asking

For my scheduler, I am using it to fire at 6 am every day and my cron notation is:

0 0 6 * * *

If you want 1:01:am then set it to

0 1 1 * * *

Complete code for the scheduler

@Scheduled(cron="0 1 1 * * *")
public void doScheduledWork() {
    //complete scheduled work
}

** VERY IMPORTANT

To be sure about the firing time correctness of your scheduler, you have to set zone value like this (I am in Istanbul):

@Scheduled(cron="0 1 1 * * *", zone="Europe/Istanbul")
public void doScheduledWork() {
    //complete scheduled work
}

You can find the complete time zone values from here.

Note: My Spring framework version is: 4.0.7.RELEASE

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

A vector is functionally same as an array. But, to the language vector is a type, and int is also a type. To a function argument, an array of any type (including vector[]) is treated as pointer. A vector<int> is not same as int[] (to the compiler). vector<int> is non-array, non-reference, and non-pointer - it is being passed by value, and hence it will call copy-constructor.

So, you must use vector<int>& (preferably with const, if function isn't modifying it) to pass it as a reference.

If you want to keep the row with the lowest id value:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MIN(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

If you want the id value that is the highest:

DELETE FROM NAMES
 WHERE id NOT IN (SELECT * 
                    FROM (SELECT MAX(n.id)
                            FROM NAMES n
                        GROUP BY n.name) x)

The subquery in a subquery is necessary for MySQL, or you'll get a 1093 error.

In my experience the Math requirement for a Computer Science degree exists simply to weed out those who will fail. If you cannot pass Calculus I and II you will most definitely not pass an advanced course on compiler construction, database or operating systems theory.

ViewFlipper loads all images into memory during layout inflating. Because my images are big it takes many memory, I replaced ViewFlipper with ImageSwitcher which can change the images with animation like ViewFlipper but it loads only one image at the time.

Date().toLocaleString() returns this: 7/31/2018, 12:58:03 PM

Pretty close - just drop the comma and the seconds:

new Date().toLocaleString().replace(",","").replace(/:.. /," ");

Results: 7/31/2018 12:58 PM

In fact, it's a good habit to check your settings before you run the app.

1. Have you check the java SDK path ?(in fact, if you have already run another app but failed to run this, which might be download from Github or others.
2. then you might have to check the flutter settings and the dart settings.

i just had the same problems - have been testing a lot of different stuff. but it just wouldn't work. then i checked the tutorial examples on jQuery.com again and found out:

your jQuery script needs to be after the elements you are referring to !

so your script needs to be after the html-code you want to access!

seems like jQuery can't access it otherwise.

Its unbelievable after so many answers, but I did it little differently in the end. I don't like primary key to be nullable, I want to have it as first argument and also want to insert without defining it and also it should not be var.

@Entity(tableName = "employments")
data class Employment(
    @PrimaryKey(autoGenerate = true) val id: Long,
    @ColumnInfo(name = "code") val code: String,
    @ColumnInfo(name = "title") val name: String
){
    constructor(code: String, name: String) : this(0, code, name)
}

I got similar task: to rsync all files modified after given date, but excluding some directories. It was difficult to build one liner all-in-one style, so I dived problem into smaller pieces. Final solution:

find  ~/sourceDIR -type f -newermt "DD MMM YYYY HH:MM:SS" | egrep -v "/\..|Downloads|FOO" > FileList.txt
rsync -v --files-from=FileList.txt ~/sourceDIR /Destination

First I use find -L ~/sourceDIR -type f -newermt "DD MMM YYYY HH:MM:SS". I tried to add regex to find line to exclude name patterns, however my flavor of Linux (Mint) seams not to understand negate regex in find. Tried number of regex flavors - non work as desired. So I end up with egrep -v - option that excludes pattern easy way. My rsync is not copying directories like /.cache or /.config plus some other I explicitly named.

just wrap your content with a table like this:

  <table width="100%" height="100%">
         <tr align="center">
               <th align="center">
                 text
               </th>
          </tr>
  </table><

It seems to be possible in iOS 5 using the UIAppearance proxy.

 [[UILabel appearance] setFont:[UIFont fontWithName:@"YourFontName" size:17.0]];

That will set the font to be whatever your custom font is for all UILabels in your app. You'll need to repeat it for each control (UIButton, UILabel, etc.).

Remember you'll need to put the UIAppFonts value in your info.plist and include the name of the font you're including.

You could add the user to the Database Level Role db_datareader.

Members of the db_datareader fixed database role can run a SELECT statement against any table or view in the database.

See Books Online for reference:

http://msdn.microsoft.com/en-us/library/ms189121%28SQL.90%29.aspx

You can add a database user to a database role using the following query:

EXEC sp_addrolemember N'db_datareader', N'userName'

I found one by Julian Bucknall on his blog here - http://www.boyet.com/Articles/PriorityQueueCSharp3.html

We modified it slightly so that low-priority items on the queue would eventually 'bubble-up' to the top over time, so they wouldn't suffer starvation.

Ctrl + Alt + L works with Android Studio under xfce4 on Linux. I see that Gnome used to use this shortcut for lock screen, but in Gnome 3 it was changed to Super+L (AKA Windows+L): https://wiki.gnome.org/Design/OS/KeyboardShortcuts

This question are greatly described here

TL;DR You are still always able to autoplay muted videos

Also, if you're want to autoplay videos on iOS add playsInline attribute, because by default iOS tries to fullscreen videos

The answers by cval and Priyank Patel work great. However, be aware that some values could be unicode strings and therefore may cause the str to throw a UnicodeEncodeError error. In that case, replace the function str by the function unicode.

For example, assume the string Libië (Dutch for Libya), represented in Python as the unicode string u'Libi\xeb':

print str(u'Libi\xeb')

throws the following error:

Traceback (most recent call last):
  File "/Users/tomasz/Python/MA-CIW-Scriptie/RecreateTweets.py", line 21, in <module>
    print str(u'Libi\xeb')
UnicodeEncodeError: 'ascii' codec can't encode character u'\xeb' in position 4: ordinal not in range(128)

The following line, however, will not throw an error:

print unicode(u'Libi\xeb') # prints Libië

So, replace:

values = ','.join([str(i) for i in value_list])

by

values = ','.join([unicode(i) for i in value_list])

to be safe.

use global scope on your $con and put it inside your getPosts() function like so.

function getPosts() {
global $con;
$query = mysqli_query($con,"SELECT * FROM Blog");
while($row = mysqli_fetch_array($query))
    {
        echo "<div class=\"blogsnippet\">";
        echo "<h4>" . $row['Title'] . "</h4>" . $row['SubHeading'];
        echo "</div>";
    }
}

In general I put it in a special folder "res" or "resources as already said, but after for the web application, I copy the log4j.properties with the ant task to the WEB-INF/classes directory. It is the same like letting the file at the root of the src/ folder but generally I prefer to see it in a dedicated folder.

With Maven, the usual place to put is in the folder src/main/resources as answered in this other post. All resources there will go to your build in the root classpath (e.g. target/classes/)

If you want a powerful logger, you can have also a look to slf4j library which is a logger facade and can use the log4j implementation behind.

var arr = [1,2,3,4,5]

function avg(arr){
  var sum = 0;
  for (var i = 0; i < arr.length; i++) {
    sum += parseFloat(arr[i])
  }
  return sum / i;
}

avg(arr) ======>>>> 3

This works with strings as numbers or numbers in the array.

Put all the ids into a variable called $ids and separate them with a ",":

$ids = "1,2,3,4,5,6";

Pass them like so:

$url = "?ids={$ids}";

Process them:

$ids = explode(",", $_GET['ids']);

It does work as below:

public interface UserRepository extends JpaRepository<User, Long> {
    @Query(value = "select * from (select (@rowid\\:=@rowid+1) as RN, u.* from USERS u, (SELECT @rowid\\:=0) as init where  LASTNAME = ?1) as total"+
        "where RN between ?#{#pageable.offset-1} and ?#{#pageable.offset + #pageable.pageSize}",
    countQuery = "SELECT count(*) FROM USERS WHERE LASTNAME = ?1",
    nativeQuery = true)
    Page<User> findByLastname(String lastname, Pageable pageable);
}

Use button from input element if you want to create button in a form. And use button tag if you want to create button for an action.

Below code will list directories and the files within the dir

def print_directory_contents(sPath):
        import os                                       
        for sChild in os.listdir(sPath):                
            sChildPath = os.path.join(sPath,sChild)
            if os.path.isdir(sChildPath):
                print_directory_contents(sChildPath)
            else:
                print(sChildPath)

Your function is:

function data(){

$a = "abc";
$b = "def";
$c = "ghi";

return array($a, $b, $c);
}

It returns an array where position 0 is $a, position 1 is $b and position 2 is $c. You can therefore access $a by doing just this:

data()[0]

If you do $myvar = data()[0] and print $myvar, you will get "abc", which was the value assigned to $a inside the function.

You can do it directly on the style:

var nFilter = document.createElement('div');
nFilter.className = 'well';
nFilter.innerHTML = '<label>'+sSearchStr+'</label>';

// Css styling
nFilter.style.width = "330px";
nFilter.style.float = "left";

// or
nFilter.setAttribute("style", "width:330px;float:left;");

Ok after having sunk way to much time into this problem this is the way I managed to get the appearance I was hoping for. I'm making it a separate answer so I can get everything in one place.

It's a combination of factors.

Firstly, don't try to get the toolbars to play nice through just themes. It seems to be impossible.

So apply themes explicitly to your Toolbars like in oRRs answer

layout/toolbar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_alignParentTop="true"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    app:theme="@style/Dark.Overlay"
    app:popupTheme="@style/Dark.Overlay.LightPopup" />

However this is the magic sauce. In order to actually get the background colors I was hoping for you have to override the background attribute in your Toolbar themes

values/styles.xml:

<!-- 
    I expected android:colorBackground to be what I was looking for but
    it seems you have to override android:background
-->
<style name="Dark.Overlay" parent="@style/ThemeOverlay.AppCompat.Dark.ActionBar">
    <item name="android:background">?attr/colorPrimary</item>
</style>

<style name="Dark.Overlay.LightPopup" parent="ThemeOverlay.AppCompat.Light">
    <item name="android:background">@color/material_grey_200</item>
</style>

then just include your toolbar layout in your other layouts

<include android:id="@+id/mytoolbar" layout="@layout/toolbar" />

and you're good to go.

Hope this helps someone else so you don't have to spend as much time on this as I have.

(if anyone can figure out how to make this work using just themes, ie not having to apply the themes explicitly in the layout files I'll gladly support their answer instead)

EDIT:

So apparently posting a more complete answer was a downvote magnet so I'll just accept the imcomplete answer above but leave this answer here in case someone actually needs it. Feel free to keep downvoting if it makes you happy though.

You can also do,

getDefaultProps: ->
  firstName: 'Rails'
  lastName: 'React'

now access, those constant (default value) using

@props.firstName

@props.lastName

Hope this help!!!.

Check if the Browser is IE -

  $ua = htmlentities($_SERVER['HTTP_USER_AGENT'], ENT_QUOTES, 'UTF-8');
  if (preg_match('~MSIE|Internet Explorer~i', $ua) || (strpos($ua, 'Trident/7.0') !== false && strpos($ua, 'rv:11.0') !== false)) {
    // do stuff for IE Here
  }

use this(assume that your table name is emails):

select * from emails as a 
inner join  
(select EmailAddress, min(Id) as id from emails 
group by EmailAddress ) as b 
on a.EmailAddress = b.EmailAddress 
and a.Id = b.id

hope this help..

Swift version: 5.1

If you have a custom struct or class and want to sort them arbitrarily, you should call sort() using a trailing closure that sorts on a field you specify. Here's an example using an array of custom structs that sorts on a particular property:

    struct User {
        var firstName: String
    }

    var users = [
        User(firstName: "Jemima"),
        User(firstName: "Peter"),
        User(firstName: "David"),
        User(firstName: "Kelly"),
        User(firstName: "Isabella")
    ]

    users.sort {
        $0.firstName < $1.firstName
    }

If you want to return a sorted array rather than sort it in place, use sorted() like this:

    let sortedUsers = users.sorted {
        $0.firstName < $1.firstName
    }

I'd suggest perl. (\d+.\d+.\d+.\d+) should probably do the trick.

EDIT: Just to make it more like a complete program, you could do something like the following (not tested):

#!/usr/bin/perl -w
use strict;

while (<>) {
    if (/(\d+\.\d+\.\d+\.\d+)/) {
        print "$1\n";
    }
}

This handles one IP per line. If you have more than one IPs per line, you need to use the /g option. man perlretut gives you a more detailed tutorial on regular expressions.

Try to use (focus) and (focusout) instead of onfocus and onfocusout

like this : -

<input name="date" type="text" (focus)="focusFunction()" (focusout)="focusOutFunction()">

also you can use like this :-

some people prefer the on- prefix alternative, known as the canonical form:

<input name="date" type="text" on-focus="focusFunction()" on-focusout="focusOutFunction()">

Know more about event binding see here.

you have to use HostListner for your use case

Angular will invoke the decorated method when the host element emits the specified event.@HostListener is a decorator for the callback/event handler method

See my Update working Plunker.

Working Example Working Stackblitz

Update

Some other events can be used in angular -

(focus)="myMethod()"
(blur)="myMethod()" 
(submit)="myMethod()"  
(scroll)="myMethod()"

I have found a solution how to style just the component element. I have not found any documentation how it works, but you can put attributes values into the component directive, under the 'host' property like this:

@Component({
    ...
    styles: [`
      :host {
        'style': 'display: table; height: 100%',
        'class': 'myClass'
      }`
})
export class MyComponent
{
    constructor() {}

    // Also you can use @HostBinding decorator
    @HostBinding('style.background-color') public color: string = 'lime';
    @HostBinding('class.highlighted') public highlighted: boolean = true;
}

UPDATE: As Günter Zöchbauer mentioned, there was a bug, and now you can style the host element even in css file, like this:

:host{ ... }

use a shell built-in let , it is similar to (( expr ))

A=1
B=1
let "C = $A + $B"
echo $C # C == 2

This problem happened with me and sovled by just add

 respond_to :html, :json

to ApplicationController file

You can Check Devise issues on Github: https://github.com/plataformatec/devise/issues/2667

gcc 7.4.0 can not compile codes as below:

#include <stdio.h>
const char * const str1 = "str1";
const char * str2 = str1;
int main() {
    printf("%s - %s\n", str1, str2);
    return 0;
}

constchar.c:3:21: error: initializer element is not constant const char * str2 = str1;

In fact, a "const char *" string is not a compile-time constant, so it can't be an initializer. But a "const char * const" string is a compile-time constant, it should be able to be an initializer. I think this is a small drawback of CLang.

A function name is of course a compile-time constant.So this code works:

void func(void)
{
    printf("func\n");
}
typedef void (*func_type)(void);
func_type f = func;
int main() {
    f();
    return 0;
}

C# does have a preprocessor. It works just slightly differently than that of C++ and C.

Here is a MSDN links - the section on all preprocessor directives.

Check the current value of your "readonly" attribute, if it's "false" (a string) or empty (undefined or "") then it's not readonly.

$('input').each(function() {
    var readonly = $(this).attr("readonly");
    if(readonly && readonly.toLowerCase()!=='false') { // this is readonly
        alert('this is a read only field');
    }
});

I am not sure if this has to be explicitly enabled anywhere..but for this to work in the first place you need to include the javadoc jar files with the related jars in your project. Then when you do a Cntrl+Space it shows autocomplete and javadocs.

Run XAMPP Control Panel as Administrator if using Windows 7 or more. Windows may block access to ports if not accessed by adminstrator user.

Edited to add information about the File API

Since I originally wrote this answer, the File API has been proposed as a standard and implemented in most browsers (as of IE 10, which added support for FileReader API described here, though not yet the File API). The API is a bit more complicated than the older Mozilla API, as it is designed to support asynchronous reading of files, better support for binary files and decoding of different text encodings. There is some documentation available on the Mozilla Developer Network as well as various examples online. You would use it as follows:

var file = document.getElementById("fileForUpload").files[0];
if (file) {
    var reader = new FileReader();
    reader.readAsText(file, "UTF-8");
    reader.onload = function (evt) {
        document.getElementById("fileContents").innerHTML = evt.target.result;
    }
    reader.onerror = function (evt) {
        document.getElementById("fileContents").innerHTML = "error reading file";
    }
}

Original answer

There does not appear to be a way to do this in WebKit (thus, Safari and Chrome). The only keys that a File object has are fileName and fileSize. According to the commit message for the File and FileList support, these are inspired by Mozilla's File object, but they appear to support only a subset of the features.

If you would like to change this, you could always send a patch to the WebKit project. Another possibility would be to propose the Mozilla API for inclusion in HTML 5; the WHATWG mailing list is probably the best place to do that. If you do that, then it is much more likely that there will be a cross-browser way to do this, at least in a couple years time. Of course, submitting either a patch or a proposal for inclusion to HTML 5 does mean some work defending the idea, but the fact that Firefox already implements it gives you something to start with.

I'm new in R, but I was using this easy method that works for me:

sample_of_diamonds <- diamonds[sample(nrow(diamonds),100),]

PS: Feel free to note if it has some drawback I'm not thinking about.

Only two Semicolons are allowed to be used in for loop.

1. Before first semicolon is the initialization part.
2. After first semicolon and before second semicolon is condition part (must result in boolean).
3. After second semicolon is variable manipulation part (increment/decrement part).

If you have do initialization of multiple variables or manipulation of multiple variables, you can achieve it by separating them with comma(,).

for(int i=0, j=5; i < 5; i++, j--)

NOTE: Multiple conditions separated by comma are NOT allowed.

for(int i=0, j=5; i < 5, j > 5; i++, j--) // This is NOT allowed.

Parsing string with moment.js.

const date = '1231231231231' //Example String date
const parsed = moment(+date);

Use -t on ls. e.g:.

ls -tr

or

ls -ltr

You can index and use a negative sign to drop the 3rd column:

data[,-3]

Or you can list only the first 2 columns:

data[,c("c1", "c2")]
data[,1:2]

Don't forget the comma and referencing data frames works like this: data[row,column]

I had a similar error (Cannot resolve the collation conflict between "SQL_Latin1_General_CP1_CI_AS" and "SQL_Latin1_General_CP1250_CI_AS" in the INTERSECT operation), when I used old jdbc driver.

I resolved this by downloading new driver from Microsoft or open-source project jTDS.

Typescript distinguishes two different kinds of modules: Internal modules are used to structure your code internally. At compile-time, you have to bring internal modules into scope using reference paths:

/// <reference path='moo.ts'/>

class bar extends moo.foo {
}

On the other hand, external modules are used to refernence external source files that are to be loaded at runtime using CommonJS or AMD. In your case, to use external module loading you have to do the following:

moo.ts

export class foo {
    test: number;
} 

app.ts

import moo = module('moo');
class bar extends moo.foo {
  test2: number;
}

Note the different way of brining the code into scope. With external modules, you have to use module with the name of the source file that contains the module definition. If you want to use AMD modules, you have to call the compiler as follows:

tsc --module amd app.ts

This then gets compiled to

var __extends = this.__extends || function (d, b) {
    function __() { this.constructor = d; }
    __.prototype = b.prototype;
    d.prototype = new __();
}
define(["require", "exports", 'moo'], function(require, exports, __moo__) {
    var moo = __moo__;

    var bar = (function (_super) {
        __extends(bar, _super);
        function bar() {
            _super.apply(this, arguments);

        }
        return bar;
    })(moo.foo);
})    

In HTML5 as such, there is no way to set the default value of the date field to today’s date? As shown in other answers, the value can be set using JavaScript, and this is usually the best approach if you wish to set the default according to what is current date to the user when the page is loaded.

HTML5 defines the valueAsDate property for input type=date elements, and using it, you could set the initial value directly from an object created e.g. by new Date(). However, e.g. IE 10 does not know that property. (It also lacks genuine support to input type=date, but that’s a different issue.)

So in practice you need to set the value property, and it must be in ISO 8601 conformant notation. Nowadays this can be done rather easily, since we can expect currenty used browsers to support the toISOString method:

<input type=date id=e>
<script>
document.getElementById('e').value = new Date().toISOString().substring(0, 10);
</script>

Release 3.2 of commons-lang will have FastDateParser class that is a thread-safe substitute of SimpleDateFormat for Gregorian calendar. See LANG-909 for more information.

When you overload in TypeScript, you only have one implementation with multiple signatures.

class Foo {
    myMethod(a: string);
    myMethod(a: number);
    myMethod(a: number, b: string);
    myMethod(a: any, b?: string) {
        alert(a.toString());
    }
}

Only the three overloads are recognized by TypeScript as possible signatures for a method call, not the actual implementation.

In your case, I would personally use two methods with different names as there isn't enough commonality in the parameters, which makes it likely the method body will need to have lots of "ifs" to decide what to do.

TypeScript 1.4

As of TypeScript 1.4, you can typically remove the need for an overload using a union type. The above example can be better expressed using:

myMethod(a: string | number, b?: string) {
    alert(a.toString());
}

The type of a is "either string or number".

I had the same problem. My project layout looked like

\---super
    \---thirdparty
        +---mod1-root
        |   +---mod1-linux32
        |   \---mod1-win32
        \---mod2-root
            +---mod2-linux32
            \---mod2-win32

In my case, I had a mistake in my pom.xmls at the modX-root-level. I had copied the mod1-root tree and named it mod2-root. I incorrectly thought I had updated all the pom.xmls appropriately; but in fact, mod2-root/pom.xml had the same group and artifact ids as mod1-root/pom.xml. After correcting mod2-root's pom.xml to have mod2-root specific maven coordinates my issue was resolved.

Building off of @gnovice's answer, you can actually create filled plots with shading only in the area between the two curves. Just use fill in conjunction with fliplr.

Example:

x=0:0.01:2*pi;                  %#initialize x array
y1=sin(x);                      %#create first curve
y2=sin(x)+.5;                   %#create second curve
X=[x,fliplr(x)];                %#create continuous x value array for plotting
Y=[y1,fliplr(y2)];              %#create y values for out and then back
fill(X,Y,'b');                  %#plot filled area

By flipping the x array and concatenating it with the original, you're going out, down, back, and then up to close both arrays in a complete, many-many-many-sided polygon.

Easiest way to set permissions to 777 is to connect to Your server through FTP Application like FileZilla, right click on folder, module_installation, and click Change Permissions - then write 777 or check all permissions.

In my case, I got this when trying to run Django tests through PyCharm. I think it is because PyCharm does not load the initial Django project settings, i.e. those that manage.py shell runs initially. One can add them to the start of the testing script or just run the tests using manage.py test.

Versions:

• Python 3.5 (in virtualenv)
• PyCharm 2016.3.2 Professional
• Django 1.10

You can do using a simple notepad and save as FILENAME.json

That's all.

After compiling it you can jar it.

java -jar AppName.jar

Try this tutorial it has the explanation and it will be helpful http://www.ccs.neu.edu/home/kathleen/classes/cs3200/JDBCtutorial.pdf

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

To list all the fields from a table in MySQL:

select * 
  from information_schema.columns 
 where table_schema = 'your_DB_name' 
   and table_name = 'Your_tablename'

simply pipeline echo with cat

For example

echo write something to file.txt | cat > file.txt

I had a similar problem, and none of the previous solutions worked for me, and I've just solved it by myself (after a few hours of frustration), so I'm going to share my solution.

My computer suddenly stopped recognizing any Android device I've plugged in after it installed Android Composite ADB Interface for my Nexus 4. I was not able to uninstall the driver, because any attempt to do so by Device Manager was unsuccessful (Device Manager stopped responding every time).

So I've solved it this way:

1. Switch Windows into safe mode
2. Uninstall Android Composite ADB Interface
3. Install old SAMSUNG Android ADB Interface
4. Switch Windows into normal mode
5. Plug-in Android device (Nexus 4 in my case)
6. Windows recognized the device as Nexus 4
7. Install driver from android-sdk/extras/google folder
8. Everything works again! :)

I needed to do this for work as a requirement to display the hours in this format. At first I tried this.

moment.utc(totalMilliseconds).format("HH:mm:ss")

However anything over 24 hours and the hours reset to 0. But the minutes and seconds were accurate. So I used only that part for the minutes and seconds.

var minutesSeconds = moment.utc(totalMilliseconds).format("mm:ss")

Now all I need is the total hours.

var hours = moment.duration(totalMilliseconds).asHours().toFixed()

And to get that format that we all want we just glue it together.

var formatted = hours + ":" + minutesSeconds

if totalMilliseconds is 894600000 this will return 249:30:00.

Hope that helped. Leave any questions in the comments. ;)

This is, unfortunately a quite common problem on Windows where the icons are either not updated or rather disappearing. I find it quite annoying. It usually is fixed by either refreshing the Windows folder (F5) or, by doing a SVN Clean up,

Right click on the folder ->  TortoiseSVN -> Clean up... 
Select Clean up working copy status

I have never been able to solve this permanently, this is only a work-around. Keeping TortoiseSVN on the latest version may or may not help.

Note that the clean up will only clean up your local working copy, it wont do anything to the actual repository. Its a safe operation.

Apparently this is not enough according to your comment. Do you have lots of other programs that are also using overlay icons? If so maybe you can find a solution in this thread: TortoiseSVN icons not showing up under Windows 7? The second most voted answer also deals with network drives etc. Its a good read.

Also, have you rebooted your computer after the install? From the TortoiseSVN FAQ:

You rebooted your PC of course after the installation? If you haven't please do so now. TortoiseSVN is a windows Explorer Shell extension and will be loaded together with Explorer.

...

Otherwise, try doing a repair install (and reboot of course).

So, I'm used to use

var nameOfList = new List("objectName", "objectName", "objectName")

This is how it works for me but might be different for you, I recommend to watch some Unity Tutorials on the Scripting API.

The most straightforward method is to use plt.tight_layout transformation which is actually more preferable as it doesn't do unnecessary cropping when using plt.savefig

import matplotlib as plt    
plt.plot([1,2,3], [1,2,3])
plt.tight_layout(pad=0)
plt.savefig('plot.png')

However, this may not be preferable for complex plots that modifies the figure. Refer to Johannes S's answer that uses plt.subplots_adjust if that's the case.

In jQuery, you can do alert($("#theid").css("width")).

-- if you haven't taken a look at jQuery, I highly recommend it; it makes many simple javascript tasks effortless.

Update

for the record, this post is 5 years old. The web has developed, moved on, etc. There are ways to do this with Plain Old Javascript, which is better.

Here's the nearly shortest possible solution to your question. The solution works in python 3.x. For python 2.x change the import to Tkinter rather than tkinter (the difference being the capitalization):

import tkinter as tk
#import Tkinter as tk  # for python 2
    
def create_window():
    window = tk.Toplevel(root)

root = tk.Tk()
b = tk.Button(root, text="Create new window", command=create_window)
b.pack()

root.mainloop()

This is definitely not what I recommend as an example of good coding style, but it illustrates the basic concepts: a button with a command, and a function that creates a window.

Got an re trick:

In [28]: import re

In [29]: x = "qwertyui"

In [30]: [x for x in re.split(r'(\w{2})', x) if x]
Out[30]: ['qw', 'er', 'ty', 'ui']

Then be a func, it might looks like:

def split(string, split_len):
    # Regex: `r'.{1}'` for example works for all characters
    regex = r'(.{%s})' % split_len
    return [x for x in re.split(regex, string) if x]

Here is the function which help you

private void saveBitmap(Bitmap bitmap,String path){
        if(bitmap!=null){
            try {
                FileOutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(path); //here is set your file path where you want to save or also here you can set file object directly

                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream); // bitmap is your Bitmap instance, if you want to compress it you can compress reduce percentage
                    // PNG is a lossless format, the compression factor (100) is ignored
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    try {
                        if (outputStream != null) {
                            outputStream.close();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }    
        }
    }

This is the sort of thing I'd normally use a scripting language for. It's very useful to have the ability to perform these sorts of transformations very simply using something like Ruby/Perl/Python (insert your favorite scripting language here).

I wouldn't normally use Java for this since it's too heavyweight in terms of development cycle/typing etc.

Note that if you want to be particular in manipulating XML, it's advisable to read the file as XML and manipulate it as such (the above scripting languages have very useful and simple APIs for doing this sort of work). A simple text search/replace can invalidate your file in terms of character encoding etc. As always, it depends on the complexity of your search/replace requirements.

In the following example I'm passing a department parameter to a stored procedure(spIncreaseTotalsRpt) and at the same time I'm creating a temp table all from an OPENQUERY. The Temp table needs to be a global Temp (##) so it can be referenced outside it's intance. By using exec sp_executesql you can pass the department parameter.

Note: be careful when using sp_executeSQL. Also your admin might not have this option available to you.

Hope this helps someone.

Problem is about too long setup file name. Change setup.exe parent folder name(short a name). And try it!.

If you're testing your app on a device > android 6.0 you have also to explicitely ask the user to grant the permission.

As you can see here READ_PHONE_STATE have a dangerous level.

If a permission have a dangerous level then the user have to accept or not this permission manually. You don't have the choice, you MUST do this

To do this from your activity execute the following code :

if the user use Android M and didn't grant the permission yet it will ask for it.

public static final int READ_PHONE_STATE_PERMISSION = 100;

  if (Build.VERSION.SDK_INT > Build.VERSION_CODES.M && checkSelfPermission(Manifest.permission.READ_PHONE_STATE)
                != PackageManager.PERMISSION_GRANTED) {
            requestPermissions(new String[]{Manifest.permission.READ_PHONE_STATE}, READ_PHONE_STATE_PERMISSION);
        }

then override onRequestPermissionsResult in your activity

@Override
    public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
        switch (requestCode){
            case READ_PHONE_STATE_PERMISSION: {
                if (grantResults[0] == PackageManager.PERMISSION_GRANTED){
                    //Permission granted do what you want from this point
                }else {
                    //Permission denied, manage this usecase
                }
            }
        }
    }

You should read this article to know more about it

When you work with unsigned types, modular arithmetic (also known as "wrap around" behavior) is taking place. To understand this modular arithmetic, just have a look at these clocks:

9 + 4 = 1 (13 mod 12), so to the other direction it is: 1 - 4 = 9 (-3 mod 12). The same principle is applied while working with unsigned types. If the result type is unsigned, then modular arithmetic takes place.

Now look at the following operations storing the result as an unsigned int:

unsigned int five = 5, seven = 7;
unsigned int a = five - seven;      // a = (-2 % 2^32) = 4294967294 

int one = 1, six = 6;
unsigned int b = one - six;         // b = (-5 % 2^32) = 4294967291

When you want to make sure that the result is signed, then stored it into signed variable or cast it to signed. When you want to get the difference between numbers and make sure that the modular arithmetic will not be applied, then you should consider using abs() function defined in stdlib.h:

int c = five - seven;       // c = -2
int d = abs(five - seven);  // d =  2

Be very careful, especially while writing conditions, because:

if (abs(five - seven) < seven)  // = if (2 < 7)
    // ...

if (five - seven < -1)          // = if (-2 < -1)
    // ...

if (one - six < 1)              // = if (-5 < 1)
    // ...

if ((int)(five - seven) < 1)    // = if (-2 < 1)
    // ...

but

if (five - seven < 1)   // = if ((unsigned int)-2 < 1) = if (4294967294 < 1)
    // ...

if (one - six < five)   // = if ((unsigned int)-5 < 5) = if (4294967291 < 5)
    // ...

If you've exported the environment variable:

export demoPath=/usr/local/demo

you can simply refer to it by name in the makefile (make imports all the environment variables you have set):

DEMOPATH = ${demoPath}    # Or $(demoPath) if you prefer.

If you've not exported the environment variable, it is not accessible until you do export it, or unless you pass it explicitly on the command line:

make DEMOPATH="${demoPath}" …

If you are using a C shell derivative, substitute setenv demoPath /usr/local/demo for the export command.

overflow:hidden (as mentioned by @Mikael S) doesn't work in every situation, but it should work in most situations.

Another option is to use the :after trick:

<div class="wrapper">
  <div class="col"></div>
  <div class="col"></div>
</div>

.wrapper {
  min-height: 1px; /* Required for IE7 */
  }

.wrapper:after {
  clear: both;
  display: block;
  height: 0;
  overflow: hidden;
  visibility: hidden;
  content: ".";
  font-size: 0;
  }

.col {
  display: inline;
  float: left;
  }

And for IE6:

.wrapper { height: 1px; }

You can try doing:

String myResource = IOUtils.toString(this.getClass().getResourceAsStream("yourfile.xml")).replace("\n","");

COMBINING BOX SHADOW AND OUTLINE.

A slight twist on Lea Hayes answer I found

input[type=text]:focus {
    box-shadow: 0 0 0 1pt red;
    outline-width: 1px;
    outline-color: red;
}

gets a really nice clean finish. No jumping in size which you get when using border-radius

Try:

SELECT * 
FROM eventList 
WHERE  `date` BETWEEN FROM_UNIXTIME(1364256001) AND FROM_UNIXTIME(1364342399)

Or

SELECT * 
FROM eventList WHERE  `date` 
BETWEEN '2013-03-26 00:00:01' AND '2013-03-26 23:59:59'

Here is how I do it by using HashSet

        HashSet<String> hs = new HashSet<string>(new String[] { "Pluto", "Earth", "Neptune" });
        String[] arr =
        {
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            "Pluto",
            "Earth",
            "Neptune",
            "Jupiter",
            "Saturn",
            "Mercury",
            // etc.
        };
        ICollection<String> coll = arr;

        String[] arrStrFiltered = coll.Where(str => hs.Contains(str)).ToArray();

HashSet is basically almost to O(1) so your complexity remains O(n).

My solution was to make all the parents 100% and set a specific percentage for each row:

html, body,div[class^="container"] ,.column {
    height: 100%;
}

.row0 {height: 10%;}
.row1 {height: 40%;}
.row2 {height: 50%;}

To install PDT (PHP Development Tools) for PHP development environment is better in Eclipse. The following are the steps to install PDT in Eclipse (I'm considering version 3.7 (Indigo)):

1. Open Eclipse (in my case Eclipse Indigo).
2. Go to Help --> Install New Software...
3. Expand the "Work with" drop down and select "Indigo - http://download.eclipse.org/releases/indigo".
4. Expand "Programming Languages" from the list.
5. Check PHP Development Tools (PDT) SDK Feature.
6. Click "Next >" at the bottom and follow the further instruction of Eclipse.
7. After successful installation of PDT: Go to Window --> Preferences and see the list as PHP at left panel.

You can achieve this with MAVEN_OPTS, for example
MAVEN_OPTS=-Dorg.slf4j.simpleLogger.defaultLogLevel=warn mvn clean

Rather than putting the system property directly on the command line. (At least for maven 3.3.1.)

Consider using ~/.mavenrc for setting MAVEN_OPTS if you would like logging changed for your login across all maven invocations.

I have encounter this issue too. And I'm running in XP SP3.

The following website http://www.docin.com/p-60410380.html# pointing out the solution. But it's simplified Chinese.

I translated its main idea into English here.

run regedit; open HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\DirectX Then you must change the following two items: Item 1: Name: Version, Type:REG_SZ, The value should be a rather little number to make the installation success.

Item 2: Name: SDKVersion. But in your machine, the name can be different, for example, it can be ManagedDirectXVersion. But the type should be REG_SZ. Type:REG_SZ, The value should be a rather little number to make the installation success.

In fact, you can refer to the DirectX.lgo file to find the exact version number.

It works for me.

If anybody is just like me willing to use jQuery, but still found himself looking to this question then this may help you guys:

https://html-online.com/articles/animated-scroll-anchorid-function-jquery/

$(document).ready(function () {_x000D_
            $("a.scrollLink").click(function (event) {_x000D_
                event.preventDefault();_x000D_
                $("html, body").animate({ scrollTop: $($(this).attr("href")).offset().top }, 500);_x000D_
            });_x000D_
        });

<a href="#anchor1" class="scrollLink">Scroll to anchor 1</a>_x000D_
<a href="#anchor2" class="scrollLink">Scroll to anchor 2</a>_x000D_
<p id="anchor1"><strong>Anchor 1</strong> - Lorem ipsum dolor sit amet, nonumes voluptatum mel ea.</p>_x000D_
<p id="anchor2"><strong>Anchor 2</strong> - Ex ignota epicurei quo, his ex doctus delenit fabellas.</p>

Now all clients allow to do it, but it's not pretty simple.
In any Telegram client:

1. Open Channel info (in app title)
2. Choose Administrators
3. Add Administrator
4. There will be no bots in contact list, so you need to search for it. Enter your bot's username
5. Clicking on it you make it as administrator.

There are two ways for writing a proper media queries in css. If you are writing media queries for larger device first, then the correct way of writing will be:

@media only screen 
and (min-width : 415px){
    /* Styles */
}

@media only screen 
and (min-width : 769px){
    /* Styles */
}

@media only screen 
and (min-width : 992px){
    /* Styles */
}

But if you are writing media queries for smaller device first, then it would be something like:

@media only screen 
and (max-width : 991px){
    /* Styles */
}

@media only screen 
and (max-width : 768px){
    /* Styles */
}

@media only screen 
and (max-width : 414px){
    /* Styles */
}

You can employ the use of data in jQuery and catch all of the events which then tests it against it's last value (untested):

$(document).ready(function() {  
    $("#fieldId").bind("keyup keydown keypress change blur", function() {
        if ($(this).val() != jQuery.data(this, "lastvalue") {
         alert("changed");
        }
        jQuery.data(this, "lastvalue", $(this).val());
    });
});

This would work pretty good against a long list of items too. Using jQuery.data means you don't have to create a javascript variable to track the value. You could do $("#fieldId1, #fieldId2, #fieldId3, #fieldId14, etc") to track many fields.

UPDATE: Added blur to the bind list.

Passing data from PHP is easy, you can generate JavaScript with it. The other way is a bit harder - you have to invoke the PHP script by a Javascript request.

An example (using traditional event registration model for simplicity):

<!-- headers etc. omitted -->
<script>
function callPHP(params) {
    var httpc = new XMLHttpRequest(); // simplified for clarity
    var url = "get_data.php";
    httpc.open("POST", url, true); // sending as POST

    httpc.onreadystatechange = function() { //Call a function when the state changes.
        if(httpc.readyState == 4 && httpc.status == 200) { // complete and no errors
            alert(httpc.responseText); // some processing here, or whatever you want to do with the response
        }
    };
    httpc.send(params);
}
</script>
<a href="#" onclick="callPHP('lorem=ipsum&foo=bar')">call PHP script</a>
<!-- rest of document omitted -->

Whatever get_data.php produces, that will appear in httpc.responseText. Error handling, event registration and cross-browser XMLHttpRequest compatibility are left as simple exercises to the reader ;)

Scenario

In a college there are many students doing different courses, and after an examination we have to prepare a marks card showing grade. I can calculate grade two ways

1. I can write some code like this

    if(totalMark <= 100 && totalMark > 90) { grade = "A+"; }
    else if(totalMark <= 90 && totalMark > 80) { grade = "A"; }
    else if(totalMark <= 80 && totalMark > 70) { grade = "B"; }
    else if(totalMark <= 70 && totalMark > 60) { grade = "C"; }

2. You can ask user to enter grade definition some where and save that data

Something like storing into a database table

In the first case the grade is common for all the courses and if the rule changes the code needs to be changed. But for second case we are giving user the provision to enter grade based on their requirement. So the code will be not be changed when the grade rules changes.

That's the important thing when you give more provision for users to define business logic. The first case is nothing but Hard Coding.

So in your question if you ask the user to enter the path of the file at the start, then you can remove the hard coded path in your code.

Select user id from list of user id:

SELECT * FROM my_table WHERE user_id IN (1,3,5,7,9,4);

HashSet is O(1) to access elements, so it certainly does matter. But maintaining order of the objects in the set isn't possible.

TreeSet is useful if maintaining an order(In terms of values and not the insertion order) matters to you. But, as you've noted, you're trading order for slower time to access an element: O(log n) for basic operations.

From the javadocs for TreeSet:

This implementation provides guaranteed log(n) time cost for the basic operations (add, remove and contains).

If you want to search for array of keys this is good

function searchKeysInMultiDimensionalArray($array, $keys)
{
    $results = array();

    if (is_array($array)) {
        $resultArray = array_intersect_key($array, array_flip($keys));
        if (!empty($resultArray)) {
            $results[] = $resultArray;
        }

        foreach ($array as $subarray) {
            $results = array_merge($results, searchKeysInMultiDimensionalArray($subarray, $keys));
        }
    }

    return $results;
}

Keys will not overwrite because each set of key => values will be in separate array in resulting array.
If you don't want duplicate keys then use this one

function searchKeysInMultiDimensionalArray($array, $keys)
{
    $results = array();

    if (is_array($array)) {
        $resultArray = array_intersect_key($array, array_flip($keys));
        if (!empty($resultArray)) {
            foreach($resultArray as $key => $single) {

                $results[$key] = $single;
            }
        }

        foreach ($array as $subarray) {
            $results = array_merge($results, searchKeysInMultiDimensionalArray($subarray, $keys));
        }
    }

    return $results;
}

The simple Python swap looks like this:

foo[i], foo[j] = foo[j], foo[i]

Now all you need to do is figure what i is, and that can easily be done with index:

i = foo.index("password2")

No, don't spoil it with a break. This is the last remaining stronghold for the use of goto.

str is text representation in bytes, unicode is text representation in characters.

You decode text from bytes to unicode and encode a unicode into bytes with some encoding.

That is:

>>> 'abc'.decode('utf-8')  # str to unicode
u'abc'
>>> u'abc'.encode('utf-8') # unicode to str
'abc'

UPD Sep 2020: The answer was written when Python 2 was mostly used. In Python 3, str was renamed to bytes, and unicode was renamed to str.

>>> b'abc'.decode('utf-8') # bytes to str
'abc'
>>> 'abc'.encode('utf-8'). # str to bytes
b'abc'

Something I found later which helped, is the .ReadWriteTimeout property. This, in addition to the .Timeout property seemed to finally cut down on the time threads would spend trying to download from a problematic server. The default time for .ReadWriteTimeout is 5 minutes, which for my application was far too long.

So, it seems to me:

.Timeout = time spent trying to establish a connection (not including lookup time) .ReadWriteTimeout = time spent trying to read or write data after connection established

More info: HttpWebRequest.ReadWriteTimeout Property

Edit:

Per @KyleM's comment, the Timeout property is for the entire connection attempt, and reading up on it at MSDN shows:

Timeout is the number of milliseconds that a subsequent synchronous request made with the GetResponse method waits for a response, and the GetRequestStream method waits for a stream. The Timeout applies to the entire request and response, not individually to the GetRequestStream and GetResponse method calls. If the resource is not returned within the time-out period, the request throws a WebException with the Status property set to WebExceptionStatus.Timeout.

(Emphasis mine.)

To expand a little on the other answers:

In the line:

def wrapper(func, *args):

The * next to args means "take the rest of the parameters given and put them in a list called args".

In the line:

    func(*args)

The * next to args here means "take this list called args and 'unwrap' it into the rest of the parameters.

So you can do the following:

def wrapper1(func, *args): # with star
    func(*args)

def wrapper2(func, args): # without star
    func(*args)

def func2(x, y, z):
    print x+y+z

wrapper1(func2, 1, 2, 3)
wrapper2(func2, [1, 2, 3])

In wrapper2, the list is passed explicitly, but in both wrappers args contains the list [1,2,3].

If you're using getApplicationContext() as Context in Activity for the dialog like this

Dialog dialog = new Dialog(getApplicationContext());

then use YourActivityName.this

Dialog dialog = new Dialog(YourActivityName.this);

If you are matching the full value of the field use

WHERE UPPER(fieldName) = 'ANGEL'

EDIT: From your comment you want to use:

SELECT 
    RPAD(a.name, 10,'=') "Nombre del Cliente"
    , RPAD(b.name, 12,'*') "Nombre del Consumidor" 
FROM 
    s_customer a, 
    s_region b 
WHERE 
    a.region_id = b.id 
    AND UPPER(a.name) LIKE '%SPORT%' 

Using switch statements like this is not the object oriented way. You should instead use the power of polymorphism. Simply write

this.do()

Having previously set up a base class:

abstract class Base {
   abstract void do();
   ...
}

which is the base class for A, B and C:

class A extends Base {
    void do() { this.doA() }
}

class B extends Base {
    void do() { this.doB() }
}

class C extends Base {
    void do() { this.doC() }
}

ssh -t 'command; bash -l'

will execute the command and then start up a login shell when it completes. For example:

ssh -t [email protected] 'cd /some/path; bash -l'

Before:

testImplementation 'junit:junit:4.12'
androidTestImplementation 'com.android.support.test:runner:1.0.2'
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'

After:

testImplementation 'junit:junit:4.12' 
androidTestImplementation 'com.android.support.test:runner:1.0.2' 
androidTestImplementation 'com.android.support.test.espresso:espresso-core:3.0.2'  

Worked for me.

There is also a type - JTokenType.Undefined.

This check must be included in @Brian Rogers answer.

token.Type == JTokenType.Undefined

Since the question is being tagged for mysql, I have the following implementation that works for me and I hope similar alternatives would be there for other RDBMS's. Here's the sql:

from table 
where ...

By default, the access modifier for a class is internal. That means to say, a class is accessible within the same assembly. But if we want the class to be accessed from other assemblies then it has to be made public.

Here is a very simple and common example.

The RSA encryption algorithm which is commonly used in secure commerce web sites, is based on the fact that it is easy to take two (very large) prime numbers and multiply them, while it is extremely hard to do the opposite - meaning: take a very large number, given which it has only two prime factors, and find them.

Try the following statement to check for existence of a table in the database:

If not exists (select name from sysobjects where name = 'tablename')

You may create the table inside the if block.

Android Market requires you to sign all apps you publish with a certificate, using a public/private key mechanism (the certificate is signed with your private key). This provides a layer of security that prevents, among other things, remote attackers from pushing malicious updates to your application to market (all updates must be signed with the same key).

From The App-Signing Guide of the Android Developer's site:

In general, the recommended strategy for all developers is to sign all of your applications with the same certificate, throughout the expected lifespan of your applications. There are several reasons why you should do so...

Using the same key has a few benefits - One is that it's easier to share data between applications signed with the same key. Another is that it allows multiple apps signed with the same key to run in the same process, so a developer can build more "modular" applications.

In kotlin don't use getters and setters as like in java.The correct format of the kotlin is given below.

val textView: TextView = findViewById(R.id.android_text) as TextView
textView.setOnClickListener {
    textView.text = getString(R.string.name)
}

To get the values from the Textview we have to use this method

 val str: String = textView.text.toString()

 println("the value is $str")

import os

os.system("pip install beautifulsoup4")

or

import subprocess

exe = subprocess.Popen("pip install beautifulsoup4")

exe_out = exe.communicate()

print(exe_out)

You might have some luck calling the Win32 API's MessageBoxA, although whether Win16 supports that particular method is for someone else to answer.

In the old days, "/opt" was used by UNIX vendors like AT&T, Sun, DEC and 3rd-party vendors to hold "Option" packages; i.e. packages that you might have paid extra money for. I don't recall seeing "/opt" on Berkeley BSD UNIX. They used "/usr/local" for stuff that you installed yourself.

But of course, the true "meaning" of the different directories has always been somewhat vague. That is arguably a good thing, because if these directories had precise (and rigidly enforced) meanings you'd end up with a proliferation of different directory names.

According to the Filesystem Hierarchy Standard, /opt is for "the installation of add-on application software packages". /usr/local is "for use by the system administrator when installing software locally".

$('#myTable').append('<tr><td>my data</td><td>more data</td></tr>');

will add a new row to the first TBODY of the table, without depending of any THEAD or TFOOT present. (I didn't find information from which version of jQuery .append() this behavior is present.)

You may try it in these examples:

<table class="t"> <!-- table with THEAD, TBODY and TFOOT -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t"> <!-- table with two TBODYs -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
<tbody>
  <tr><td>1</td><td>2</td></tr>
</tbody>
<tbody>
  <tr><td>3</td><td>4</td></tr>
</tbody>
<tfoot>
  <tr><th>f1</th><th>f2</th></tr>
</tfoot>
</table><br>

<table class="t">  <!-- table without TBODY -->
<thead>
  <tr><th>h1</th><th>h2</th></tr>
</thead>
</table><br>

<table class="t">  <!-- table with TR not in TBODY  -->
  <tr><td>1</td><td>2</td></tr>
</table>
<br>
<table class="t">
</table>

<script>
$('.t').append('<tr><td>a</td><td>a</td></tr>');
</script>

In which example a b row is inserted after 1 2, not after 3 4 in second example. If the table were empty, jQuery creates TBODY for a new row.

This is PKCS#1 format of a private key. Try this code. It doesn't use Bouncy Castle or other third-party crypto providers. Just java.security and sun.security for DER sequece parsing.

If anybody still facing the error with using google's design library as mentioned in the answer then, please use this as commented by @h_k which is -

Instead of calling setError on TextInputLayout, You might be using setError on EditText itself.

I just wanna add this, when you access the position of the array like

arg[n]

is the same as

*(arg + n) than means an offset of n starting from de arg address.

so arg[0] will be *arg

Checkout the following article on MSDN about examples of the N format. This is also covered in the Standard Numeric Format Strings article.

Relevant excerpts:

//       Formatting of 1054.32179:
//          N:                     1,054.32 
//          N0:                    1,054 
//          N1:                    1,054.3 
//          N2:                    1,054.32 
//          N3:                    1,054.322 

When precision specifier controls the number of fractional digits in the result string, the result string reflects a number that is rounded to a representable result nearest to the infinitely precise result. If there are two equally near representable results:

• On the .NET Framework and .NET Core up to .NET Core 2.0, the runtime selects the result with the greater least significant digit (that is, using MidpointRounding.AwayFromZero).
• On .NET Core 2.1 and later, the runtime selects the result with an even least significant digit (that is, using MidpointRounding.ToEven).

git add . equals git add -A . adds files to index only from current and children folders.

git add -A adds files to index from all folders in working tree.

P.S.: information relates to Git 2.0 (2014-05-28).

>>> l = [19, 1, 2, 3, 4, 20, 20]

One way to achieve it is to wrap your input in <form> tag and reset it.

I'm not considering attaching thr form to NgForm or FormControl either.

@Component({
  selector: 'form-component',
  template: `
    <form #form>
      <input type="file" placeholder="File Name" name="filename">
    </form>
    <button (click)="reset()">Reset</button>
`
})
class FormComponent {



  @ViewChild('form') form;


  reset() {
    this.form.nativeElement.reset()
  }
}

This is a mismatch between assemblies: a DLL referenced from an assembly doesn't have a method signature that's expected.

Clean the solution, rebuild everything, and try again.

Also, be careful if this is a reference to something that's in the GAC; it could be that something somewhere is pointing to an incorrect version. Make sure (through the Properties of each reference) that the correct version is chosen or that Specific Version is set false.

You need to install ENU\x64\SQLEXPRWT_x64_ENU.exe which is Express with Tools (RTM release. SP1 release can be found here).

As the page states

Express with Tools (with LocalDB) Includes the database engine and SQL Server Management Studio Express) This package contains everything needed to install and configure SQL Server as a database server. Choose either LocalDB or Express depending on your needs above.

So install this and use the management studio included with it.

Some time we need to set PATH variable for WINDOWS

%USERPROFILE%\AppData\Roaming\npm

After that test with where grunt

Note: Do not forget to close the command prompt window and reopen it.

For those people who use Kotlin do this instead:

1. Create a method with a parameter containing String Object.
2. Navigate to another Activity

For Example,

// * The Method I Mentioned Above 
private fun parseTheValue(@NonNull valueYouWantToParse: String)
{
     val intent = Intent(this, AnotherActivity::class.java)
     intent.putExtra("value", valueYouWantToParse)
     intent.addFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
     startActivity(intent)
     this.finish()
}

Then just call parseTheValue("the String that you want to parse")

e.g,

val theValue: String
 parseTheValue(theValue)

then in the other activity,

val value: Bundle = intent.extras!!
// * enter the `name` from the `@param`
val str: String = value.getString("value").toString()

// * For testing
println(str)

Hope This Help, Happy Coding!

You probably want to create a type by using the Folding Pattern:

    // Here is the constructor section.
    var myType = function () {
        var N = {}, // Enclosed (private) members are here.
            X = this; // Exposed (public) members are here.

        (function ENCLOSED_FIELDS() {
            N.toggle = false;
            N.text = '';
        }());

        (function EXPOSED_FIELDS() {
            X.count = 0;
            X.numbers = [1, 2, 3];
        }());

        // The properties below have access to the enclosed fields.
        // Careful with functions exposed within the closure of the
        // constructor, each new instance will have it's own copy.
        (function EXPOSED_PROPERTIES_WITHIN_CONSTRUCTOR() {
            Object.defineProperty(X, 'toggle', {
                get: function () {
                    var before = N.toggle;
                    N.toggle = !N.toggle;
                    return before;
                }
            });

            Object.defineProperty(X, 'text', {
                get: function () {
                    return N.text;
                },
                set: function (value) {
                    N.text = value;
                }
            });
        }());
    };

    // Here is the prototype section.
    (function PROTOTYPE() {
        var P = myType.prototype;

        (function EXPOSED_PROPERTIES_WITHIN_PROTOTYPE() {
            Object.defineProperty(P, 'numberLength', {
                get: function () {
                    return this.numbers.length;
                }
            });
        }());

        (function EXPOSED_METHODS() {
            P.incrementNumbersByCount = function () {
                var i;
                for (i = 0; i < this.numbers.length; i++) {
                    this.numbers[i] += this.count;
                }
            };
            P.tweak = function () {
                if (this.toggle) {
                    this.count++;
                }
                this.text = 'tweaked';
            };
        }());
    }());

That code will give you a type called myType. It will have internal private fields called toggle and text. It will also have these exposed members: the fields count and numbers; the properties toggle, text and numberLength; the methods incrementNumbersByCount and tweak.

The Folding Pattern is fully detailed here: Javascript Folding Pattern

Here is a simple approach in up to 4 steps:

0 - Advise the team you are going to fix the repository

Connect with the team and let them know of the upcoming changes.

1 - Remove the last commit

Assuming your target branch is master:

$ git checkout master              # move to the target branch
$ git reset --hard HEAD^           # remove the last commit
$ git push -f                      # push to fix the remote

At this point you are done if you are working alone.

2 - Fix your teammate's local repositories

On your teammate's:

$ git checkout master              # move to the target branch
$ git fetch                        # update the local references but do not merge  
$ git reset --hard origin/master   # match the newly fetched remote state

If your teammate had no new commits, you are done at this point and you should be in sync.

3 - Bringing back lost commits

Let's say a teammate had a new and unpublished commit that were lost in this process.

$ git reflog                       # find the new commit hash
$ git cherry-pick <commit_hash>

Do this for as many commits as necessary.

I have successfully used this approach many times. It requires a team effort to make sure everything is synchronized.

1. you need to convert SVG to XML to use in android project.

1.1 you can do this with this site: http://inloop.github.io/svg2android/ but it does not support all the features of SVG like some gradients.

1.2 you can convert via android studio but it might use some features that only supports API 24 and higher that cuase crashe your app in older devices.

and add vectorDrawables.useSupportLibrary = true in gradle file and use like this:

<android.support.v7.widget.AppCompatImageView
                android:layout_width="match_parent"
                android:layout_height="match_parent"
                app:srcCompat="@drawable/ic_item1" />

2. use this library https://github.com/MegatronKing/SVG-Android that supports these features : https://github.com/MegatronKing/SVG-Android/blob/master/support_doc.md

add this code in application class:

public void onCreate() {
    SVGLoader.load(this)
}

and use the SVG like this :

<ImageView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:src="@drawable/ic_android_red"/>

Others have provided answers for how to change the title size, but as for the axes tick label size, you can also use the set_tick_params method.

E.g., to make the x-axis tick label size small:

ax.xaxis.set_tick_params(labelsize='small')

or, to make the y-axis tick label large:

ax.yaxis.set_tick_params(labelsize='large')

You can also enter the labelsize as a float, or any of the following string options: 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', or 'xx-large'.

Months are zero-based in Calendar. So 12 is interpreted as december + 1 month. Use

c.set(year, month - 1, day, 0, 0);  

For anybody reading this in 2019, after React 16.8 was released, take a look at the React Hooks. It really simplifies handling states in components. The docs are very well written with an example of exactly what you need.

Here are a few options for changing text / label sizes

library(ggplot2)

# Example data using mtcars

a <- aggregate(mpg ~ vs + am , mtcars, function(i) round(mean(i)))

p <- ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
            geom_bar(stat="identity",position="dodge") + 
            geom_text(data = a, aes(label = mpg), 
                            position = position_dodge(width=0.9),  size=20)

The size in the geom_text changes the size of the geom_text labels.

p <- p + theme(axis.text = element_text(size = 15)) # changes axis labels

p <- p + theme(axis.title = element_text(size = 25)) # change axis titles

p <- p + theme(text = element_text(size = 10)) # this will change all text size 
                                                             # (except geom_text)

For this And why size of 10 in geom_text() is different from that in theme(text=element_text()) ?

Yes, they are different. I did a quick manual check and they appear to be in the ratio of ~ (14/5) for geom_text sizes to theme sizes.

So a horrible fix for uniform sizes is to scale by this ratio

geom.text.size = 7
theme.size = (14/5) * geom.text.size

ggplot(mtcars, aes(factor(vs), y=mpg, fill=factor(am))) + 
  geom_bar(stat="identity",position="dodge") + 
  geom_text(data = a, aes(label = mpg), 
            position = position_dodge(width=0.9),  size=geom.text.size) + 
  theme(axis.text = element_text(size = theme.size, colour="black")) 

This of course doesn't explain why? and is a pita (and i assume there is a more sensible way to do this)

The simplest way ist just to start it with start

start notepad.exe

Here you can find more information about start

I caused this problem by entering an extra blank line at the end of ~/.android/adb_usb.ini

(Removing the extra blank line fixed the problem)

gravity--Applies to its own view.

layout-gravity---Applies to view related to its parent.

This is the simple example to use both of them:

import {
  Directive, HostListener, HostBinding
}
from '@angular/core';

@Directive({
  selector: '[Highlight]'
})
export class HighlightDirective {
  @HostListener('mouseenter') mouseover() {
    this.backgroundColor = 'green';
  };

  @HostListener('mouseleave') mouseleave() {
    this.backgroundColor = 'white';
  }

  @HostBinding('style.backgroundColor') get setColor() {
     return this.backgroundColor;
  };

  private backgroundColor = 'white';
  constructor() {}

}

Introduction:

1. HostListener can bind an event to the element.

2. HostBinding can bind a style to the element.

3. this is directive, so we can use it for

   Some Text

4. So according to the debug, we can find that this div has been binded style = "background-color:white"

   Some Text

5. we also can find that EventListener of this div has two event: mouseenter and mouseleave. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.

You can do that with a grid:

article {
    display: grid;
}

.one {
    grid-area: 1 / 1 / 2 / 2;
}

.two {
    grid-area: 1 / 1 / 2 / 2;
}

I would consider to refactor the service to return your domain object rather than JSON strings and let Spring handle the serialization (via the MappingJacksonHttpMessageConverter as you write). As of Spring 3.1, the implementation looks quite neat:

@RequestMapping(produces = MediaType.APPLICATION_JSON_VALUE, 
    method = RequestMethod.GET
    value = "/foo/bar")
@ResponseBody
public Bar fooBar(){
    return myService.getBar();
}

Comments:

First, the <mvc:annotation-driven /> or the @EnableWebMvc must be added to your application config.

Next, the produces attribute of the @RequestMapping annotation is used to specify the content type of the response. Consequently, it should be set to MediaType.APPLICATION_JSON_VALUE (or "application/json").

Lastly, Jackson must be added so that any serialization and de-serialization between Java and JSON will be handled automatically by Spring (the Jackson dependency is detected by Spring and the MappingJacksonHttpMessageConverter will be under the hood).

The easiest is to put overflow:hidden on the parent div and don't specify a height:

#parent { overflow: hidden }

Another way is to also float the parent div:

#parent { float: left; width: 100% }

Another way uses a clear element:

<div class="parent">
   <img class="floated_child" src="..." />
   <span class="clear"></span>
</div>

CSS

span.clear { clear: left; display: block; }

Define the helper:

remove-warning () {
    grep -v 'mysql: [Warning] Using a password on the command line interface can be insecure.'
}

Use it:

mysql -u $user -p$password -e "statement" 2>&1 | remove-warning

Tachaan! Your code is clean and nice to read

(tested with bash)

Define will make the constant available everywhere in your class without needing to use global, while the variable requires global in the class, I would use DEFINE. but again, if the db params should change during program execution you might want to stick with variable.

Me did not nothing, just copied development Bin folder DLLs to online deployed Bin folder and it worked fine for me.

The error is because there is some non-ascii character in the dictionary and it can't be encoded/decoded. One simple way to avoid this error is to encode such strings with encode() function as follows (if a is the string with non-ascii character):

a.encode('utf-8').strip()

Another option besides those above is:

df = df.groupby(df.columns, axis = 1).transform(lambda x: x.fillna(x.mean()))

It's less elegant than previous responses for mean, but it could be shorter if you desire to replace nulls by some other column function.

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

// or considering your array structure:

$array = array(
  'string1' => array('a' => '', 'b' => '', 'c' => ''),
  'string2' => array('a' => '', 'b' => '', 'c' => ''),
  'string3' => array('a' => '', 'b' => '', 'c' => ''),
);

// you could just

function findIndexOfKey($key_to_index,$array){
  return array_search($key_to_index,array_keys($array));
}

// executed

print "\r\n//-- Method 1 --//\r\n";
print '#index of: string1 = '.findIndexofKey('string1',$array)."\r\n";
print '#index of: string2 = '.findIndexofKey('string2',$array)."\r\n";
print '#index of: string3 = '.findIndexofKey('string3',$array)."\r\n";

// alternatively

print "\r\n//-- Method 2 --//\r\n";
print '#index of: string1 = '.array_search('string1',array_keys($array))."\r\n";
print '#index of: string2 = '.array_search('string2',array_keys($array))."\r\n";
print '#index of: string3 = '.array_search('string3',array_keys($array))."\r\n";

// recursersively

print "\r\n//-- Method 3 --//\r\n";
foreach(array_keys($array) as $key => $value){
  print '#index of: '.$value.' = '.$key."\r\n";
}

// outputs

//-- Method 1 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

//-- Method 2 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

//-- Method 3 --//
#index of: string1 = 0
#index of: string2 = 1
#index of: string3 = 2

There are some things to be considered in your code.

First, write those headers correctly. You will never see any server sending Content-type:application/pdf, the header is Content-Type: application/pdf, spaced, with capitalized first letters etc.

The file name in Content-Disposition is the file name only, not the full path to it, and altrough I don't know if its mandatory or not, this name comes wrapped in " not '. Also, your last ' is missing.

Content-Disposition: inline implies the file should be displayed, not downloaded. Use attachment instead.

In addition, make the file extension in upper case to make it compatible with some mobile devices. (Update: Pretty sure only Blackberries had this problem, but the world moved on from those so this may be no longer a concern)

All that being said, your code should look more like this:

<?php

    $filename = './pdf/jobs/pdffile.pdf';

    $fileinfo = pathinfo($filename);
    $sendname = $fileinfo['filename'] . '.' . strtoupper($fileinfo['extension']);

    header('Content-Type: application/pdf');
    header("Content-Disposition: attachment; filename=\"$sendname\"");
    header('Content-Length: ' . filesize($filename));
    readfile($filename);

Content-Length is optional but is also important if you want the user to be able to keep track of the download progress and detect if the download was interrupted. But when using it you have to make sure you won't be send anything along with the file data. Make sure there is absolutely nothing before <?php or after ?>, not even an empty line.

Just add style="width:auto"

<input type="submit" id="search" value="Search" style="width:auto" />

This worked for me in IE, Firefox and Chrome.

for those developers who came to this question about checking where they can return null from component instead of checking in ternary mode to render or not render the component, the answer is YES, You Can!

i mean instead of this junk ternary condition inside your jsx in render part of your component:

// some component body
return(
  <section>
   {/* some ui */}
   
   { someCondition && <MyComponent /> }
   or
   { someCondition ? <MyComponent /> : null }

   {/* more ui */}
  </section>
)

you can check than condition inside your component like:

const MyComponent:React.FC = () => {
  
  // get someCondition from context at here before any thing


  if(someCondition) return null; // i mean this part , checking inside component! 
  
  return (
    <section>   
     // some ui...
    </section>
  )
}

Just Consider that in my case i provide the someCondition variable from a context in upper level component ( for example, just consider in your mind ) and i don't need to prop drill the someCondition inside MyComponent.

Just look how clean view your code gets after that, i mean you don't need to user ternary operator inside your JSX, and your parent component would like below:

// some component body
return(
  <section>
   {/* some ui */}
   
   <MyComponent />

   {/* more ui */}
  </section>
)

and MyComponent would handle the rest for you!

Going to keep this pithier, this is already asked and answered above .

I'd step back however and answer it slightly differently, the docker engine itself adds orchestration as one of its extras and this is the disruptive part. Once you start running an app as a combination of containers running 'somewhere' across multiple container engines it gets really exciting. Robustness, Horizontal Scaling, complete abstraction from the underlying hardware, i could go on and on...

Its not just Docker that gives you this, in fact the de facto Container Orchestration standard is Kubernetes which comes in a lot of flavours, a Docker one, but also OpenShift, SuSe, Azure, AWS...

Then beneath K8S there are alternative container engines; the interesting ones are Docker and CRIO - recently built, daemonless, intended as a container engine specifically for Kubernetes but immature. Its the competition between these that I think will be the real long term choice for a container engine.

To prevent that people are mislead by some of the comments to the other answers:

1. If .schema or query from sqlite_master not gives any output, it indicates a non-existent tablename, e.g. this may also be caused by a ; semicolon at the end for .schema, .tables, ... Or just because the table really not exists. That .schema just doesn't work is very unlikely and then a bug report should be filed at the sqlite project.

... .schema can only be used from a command line; the above commands > can be run as a query through a library (Python, C#, etc.). – Mark Rushakoff Jul 25 '10 at 21:09

2. 'can only be used from a command line' may mislead people. Almost any (likely every?) programming language can call other programs/commands. Therefore the quoted comment is unlucky as calling another program, in this case sqlite, is more likely to be supported than that the language provides a wrapper/library for every program (which not only is prone to incompleteness by the very nature of the masses of programs out there, but also is counter acting single-source principle, complicating maintenance, furthering the chaos of data in the world).

there is also http://ideone.com/ (supports many languages)

Depending on the encoding you wish to use:

var str = System.Text.Encoding.Default.GetString(result);

For this issue need to add the partition for date column values, If last partition 20201231245959, then inserting the 20210110245959 values, this issue will occurs.

For that need to add the 2021 partition into that table

ALTER TABLE TABLE_NAME ADD PARTITION PARTITION_NAME VALUES LESS THAN (TO_DATE('2021-12-31 24:59:59', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')) NOCOMPRESS

If you're using AD you can use serverless binding to locate a domain controller for the default domain, then use LDAP://rootDSE to get information about the directory server, as described in the linked article.

Unless I misunderstand your question, you can just open a file read only. Here is a simply example, without any checks.

To get the file path from the user use this function:

Private Function get_user_specified_filepath() As String
    'or use the other code example here.
    Dim fd As Office.FileDialog
    Set fd = Application.FileDialog(msoFileDialogFilePicker)
    fd.AllowMultiSelect = False
    fd.Title = "Please select the file."
    get_user_specified_filepath = fd.SelectedItems(1)
End Function

Then just open the file read only and assign it to a variable:

dim wb as workbook
set wb = Workbooks.Open(get_user_specified_filepath(), ReadOnly:=True)

As Gerben suggested, just change:

order deny,allow
deny from all

to

order allow,deny

And the restrictions will work as you want them to.

Details can be found in Apache's docs.

Here's a Swift version:

func durationsBySecond(seconds s: Int) -> (days:Int,hours:Int,minutes:Int,seconds:Int) {
    return (s / (24 * 3600),(s % (24 * 3600)) / 3600, s % 3600 / 60, s % 60)
}

Can be used like this:

let (d,h,m,s) = durationsBySecond(seconds: duration)
println("time left: \(d) days \(h) hours \(m) minutes \(s) seconds")

Why so complicated? This is how I do it...

Swift 4:

var iPad : Bool {
    return UIDevice.current.model.contains("iPad")
}

This way you can just say if iPad {}

Correct syntax looks like this. See MSDN.

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p

  ON p.vTreasuryId COLLATE Latin1_General_CI_AS = f.RFC COLLATE Latin1_General_CI_AS 

I had the same issue when working in a solution with multiple projects that share code. Turned out that I forgot to update the DLL in the folder of the 2nd project.

My suggestion is to take a good look at the 'project' column in the Error list window and make sure that project also uses the right DLL.

Old way but still working!

 int[] values = {1,2,3,4};
 List<Integer> list = new ArrayList<>(values.length);

 for(int valor : values) {
     list.add(valor);
 }

Just set the property of textbox that is PasswordChar and set the * as a property of textbox. That will work for password.

  passwordtextbox.PasswordChar = '*';

where passwordtextbox is the text box name.

1. You don't need:

   @Configuration
   @ComponentScan("com.company.praktikant")
   

   @EnableWebSecurity already has @Configuration in it, and I cannot imagine why you put @ComponentScan there.

2. About CORS filter, I would just put this:

   @Bean
   public FilterRegistrationBean corsFilter() {
       UrlBasedCorsConfigurationSource source = new UrlBasedCorsConfigurationSource();
       CorsConfiguration config = new CorsConfiguration();
       config.setAllowCredentials(true);
       config.addAllowedOrigin("*");
       config.addAllowedHeader("*");
       config.addAllowedMethod("*");
       source.registerCorsConfiguration("/**", config);
       FilterRegistrationBean bean = new FilterRegistrationBean(new CorsFilter(source));
       bean.setOrder(0); 
       return bean;
   }
   

   Into SecurityConfiguration class and remove configure and configure global methods. You don't need to set allowde orgins, headers and methods twice. Especially if you put different properties in filter and spring security config :)

3. According to above, your "MyFilter" class is redundant.

4. You can also remove those:

   final AnnotationConfigApplicationContext annotationConfigApplicationContext = new AnnotationConfigApplicationContext();
   annotationConfigApplicationContext.register(CORSConfig.class);
   annotationConfigApplicationContext.refresh();
   

   From Application class.

5. At the end small advice - not connected to the question. You don't want to put verbs in URI. Instead of http://localhost:8080/getKunden you should use HTTP GET method on http://localhost:8080/kunden resource. You can learn about best practices for design RESTful api here: http://www.vinaysahni.com/best-practices-for-a-pragmatic-restful-api

You can run the command in the background by adding a & at the end of it as:

exec('run_baby_run &');

But doing this alone will hang your script because:

If a program is started with exec function, in order for it to continue running in the background, the output of the program must be redirected to a file or another output stream. Failing to do so will cause PHP to hang until the execution of the program ends.

So you can redirect the stdout of the command to a file, if you want to see it later or to /dev/null if you want to discard it as:

exec('run_baby_run > /dev/null &');

You are really mixing together two different things.

Use dir(), vars() or the inspect module to get what you are interested in (I use __builtins__ as an example; you can use any object instead).

>>> l = dir(__builtins__)
>>> d = __builtins__.__dict__

Print that dictionary however fancy you like:

>>> print l
['ArithmeticError', 'AssertionError', 'AttributeError',...

or

>>> from pprint import pprint
>>> pprint(l)
['ArithmeticError',
 'AssertionError',
 'AttributeError',
 'BaseException',
 'DeprecationWarning',
...

>>> pprint(d, indent=2)
{ 'ArithmeticError': <type 'exceptions.ArithmeticError'>,
  'AssertionError': <type 'exceptions.AssertionError'>,
  'AttributeError': <type 'exceptions.AttributeError'>,
...
  '_': [ 'ArithmeticError',
         'AssertionError',
         'AttributeError',
         'BaseException',
         'DeprecationWarning',
...

Pretty printing is also available in the interactive debugger as a command:

(Pdb) pp vars()
{'__builtins__': {'ArithmeticError': <type 'exceptions.ArithmeticError'>,
                  'AssertionError': <type 'exceptions.AssertionError'>,
                  'AttributeError': <type 'exceptions.AttributeError'>,
                  'BaseException': <type 'exceptions.BaseException'>,
                  'BufferError': <type 'exceptions.BufferError'>,
                  ...
                  'zip': <built-in function zip>},
 '__file__': 'pass.py',
 '__name__': '__main__'}

Just looking at the message it sounds like one or more of the components that you reference, or one or more of their dependencies is not registered properly.

If you know which component it is you can use regsvr32.exe to register it, just open a command prompt, go to the directory where the component is and type regsvr32 filename.dll (assuming it's a dll), if it works, try to run the code again otherwise come back here with the error.

If you don't know which component it is, try re-installing/repairing the GIS software (I assume you've installed some GIS software that includes the component you're trying to use).

In both your examples, local variables of Object* type are allocated on the stack. The compiler is free to produce the same code from both snippets if there is no way for your program to detect a difference.

The memory area for global variables is the same as the memory area for static variables - it's neither on the stack nor on the heap. You can place variables in that area by declaring them static inside the function. The consequence of doing so is that the instance becomes shared among concurrent invocations of your function, so you need to carefully consider synchronization when you use statics.

Here is a link to a discussion of the memory layout of a running C program.

private void button1_Click(object sender, EventArgs e)
{
      Form2 m = new Form2();
      m.Show();
      this.Visible = false;
}

You should target the smallest, not the largest, supported pixel resolution by the devices your app can run on.

Say if there's an actual Mac computer that can run OS X 10.9 and has a native screen resolution of only 1280x720 then that's the resolution you should focus on. Any higher and your game won't correctly run on this device and you could as well remove that device from your supported devices list.

You can rely on upscaling to match larger screen sizes, but you can't rely on downscaling to preserve possibly important image details such as text or smaller game objects.

The next most important step is to pick a fitting aspect ratio, be it 4:3 or 16:9 or 16:10, that ideally is the native aspect ratio on most of the supported devices. Make sure your game only scales to fit on devices with a different aspect ratio.

You could scale to fill but then you must ensure that on all devices the cropped areas will not negatively impact gameplay or the use of the app in general (ie text or buttons outside the visible screen area). This will be harder to test as you'd actually have to have one of those devices or create a custom build that crops the view accordingly.

Alternatively you can design multiple versions of your game for specific and very common screen resolutions to provide the best game experience from 13" through 27" displays. Optimized designs for iMac (desktop) and a Macbook (notebook) devices make the most sense, it'll be harder to justify making optimized versions for 13" and 15" plus 21" and 27" screens.

But of course this depends a lot on the game. For example a tile-based world game could simply provide a larger viewing area onto the world on larger screen resolutions rather than scaling the view up. Provided that this does not alter gameplay, like giving the player an unfair advantage (specifically in multiplayer).

You should provide @2x images for the Retina Macbook Pro and future Retina Macs.

With the new version of sdk, the accepted answer does not work - it does not wait for the object to be downloaded. The following code snippet will help with the new version:

// dependencies

const AWS = require('aws-sdk');

// get reference to S3 client

const s3 = new AWS.S3();

exports.handler = async (event, context, callback) => {

var bucket = "TestBucket"

var key = "TestKey"

   try {

      const params = {
            Bucket: Bucket,
            Key: Key
        };

       var theObject = await s3.getObject(params).promise();

    } catch (error) {
        console.log(error);
        return;
    }  
}

After some tries, these are the samples I am using in order to connect:

Specifying the username and the password:

sqlcmd -S 211.11.111.111 -U NotSA -P NotTheSaPassword

Specifying the DB as well:

sqlcmd -S 211.11.111.111 -d SomeSpecificDatabase -U NotSA -P NotTheSaPassword

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

using recursion

let myArr = [1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16];
let size = 4; //Math.sqrt(myArr.length); --> For a n x n matrix
let tempArr = [];
function createMatrix(arr, i) {
    if (arr.length !== 0) {
      if(i % size == 0) {
        tempArr.push(arr.splice(0,size))
      } 
      createMatrix(arr, i - 1)
    }
}
createMatrix(myArr, myArr.length);
console.log(tempArr);

Note: The existing array i.e. myArr will be modified.

empty is an operator:

The empty operator is a prefix operation that can be used to determine whether a value is null or empty.

<c:if test="${empty myObject.featuresList}">

There is a possibility that your IP/host are blocked by the remote host, especially if it thinks you are hitting it too hard.

Examples with Types:

// create a tree structure for an object. You can't do the same with interface because of lack of intersection (&)

type Tree<T> = T & { parent: Tree<T> };

// type to restrict a variable to assign only a few values. Interfaces don't have union (|)

type Choise = "A" | "B" | "C";

// thanks to types, you can declare NonNullable type thanks to a conditional mechanism.

type NonNullable<T> = T extends null | undefined ? never : T;

Examples with Interface:

// you can use interface for OOP and use 'implements' to define object/class skeleton

interface IUser {
    user: string;
    password: string;
    login: (user: string, password: string) => boolean;
}

class User implements IUser {
    user = "user1"
    password = "password1"

    login(user: string, password: string) {
        return (user == user && password == password)
    }
}

// you can extend interfaces with other interfaces

    interface IMyObject {
        label: string,
    }

    interface IMyObjectWithSize extends IMyObject{
        size?: number
    }

dochoffiday's answer is a great starting point, but for me it did not cut it (the CSS part needed a buff) so I made a modified version with several improvements.

See it in action, then come back for the description.

JavaScript

(function ($) {
    $.fn.styleTable = function (options) {
        var defaults = {
            css: 'ui-styled-table'
        };
        options = $.extend(defaults, options);

        return this.each(function () {
            $this = $(this);
            $this.addClass(options.css);

            $this.on('mouseover mouseout', 'tbody tr', function (event) {
                $(this).children().toggleClass("ui-state-hover",
                                               event.type == 'mouseover');
            });

            $this.find("th").addClass("ui-state-default");
            $this.find("td").addClass("ui-widget-content");
            $this.find("tr:last-child").addClass("last-child");
        });
    };
})(jQuery);

Differences with the original version:

• the default CSS class has been changed to ui-styled-table (it sounds more consistent)
• the .live call was replaced with the recommended .on for jQuery 1.7 upwards
• the explicit conditional has been replaced by .toggleClass (a terser equivalent)
• code that sets the misleadingly-named CSS class first on table cells has been removed
• the code that dynamically adds .last-child to the last table row is necessary to fix a visual glitch on Internet Explorer 7 and Internet Explorer 8; for browsers that support :last-child it is not necessary

CSS

/* Internet Explorer 7: setting "separate" results in bad visuals; all other browsers work fine with either value. */
/* If set to "separate", then this rule is also needed to prevent double vertical borders on hover:
table.ui-styled-table tr * + th, table.ui-styled-table tr * + td  { border-left-width: 0px !important; } */
table.ui-styled-table { border-collapse: collapse; }

/* Undo the "bolding" that jQuery UI theme may cause on hovered elements
/* Internet Explorer 7: does not support "inherit", so use a MS proprietary expression along with an Internet Explorer <= 7 targeting hack
        to make the visuals consistent across all supported browsers */
table.ui-styled-table td.ui-state-hover {
    font-weight: inherit;
    *font-weight: expression(this.parentNode.currentStyle['fontWeight']);
}

/* Initally remove bottom border for all cells. */
table.ui-styled-table th, table.ui-styled-table td { border-bottom-width: 0px !important; }

/* Hovered-row cells should show bottom border (will be highlighted) */
table.ui-styled-table tbody tr:hover th,
table.ui-styled-table tbody tr:hover td
{ border-bottom-width: 1px !important; }

/* Remove top border if the above row is being hovered to prevent double horizontal borders. */
table.ui-styled-table tbody tr:hover + tr th,
table.ui-styled-table tbody tr:hover + tr td
{ border-top-width: 0px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 7, Internet Explorer 8: selector dependent on CSS classes because of no support for :last-child */
table.ui-styled-table tbody tr.last-child th,
table.ui-styled-table tbody tr.last-child td
{ border-bottom-width: 1px !important; }

/* Last-row cells should always show bottom border (not necessarily highlighted if not hovered). */
/* Internet Explorer 8 BUG: if these (unsupported) selectors are added to a rule, other selectors for that rule will stop working as well! */
/* Internet Explorer 9 and later, Firefox, Chrome: make sure the visuals are working even without the CSS classes crutch. */
table.ui-styled-table tbody tr:last-child th,
table.ui-styled-table tbody tr:last-child td
{ border-bottom-width: 1px !important; }

Notes

I have tested this on Internet Explorer 7 and upwards, Firefox 11 and Google Chrome 18 and confirmed that it works perfectly. I have not tested reasonably earlier versions of Firefox and Chrome or any version of Opera; however, those browsers are well-known for good CSS support and since we are not using any bleeding-edge functionality here I assume it will work just fine there as well.

If you are not interested in Internet Explorer 7 support there is one CSS attribute (introduced with the star hack) that can go.

If you are not interested in Internet Explorer 8 support either, the CSS and JavaScript related to adding and targeting the last-child CSS class can go as well.

Setting the canvas coordinate space width and height based on the browser client's dimensions requires you to resize and redraw whenever the browser is resized.

A less convoluted solution is to maintain the drawable dimensions in Javascript variables, but set the canvas dimensions based on the screen.width, screen.height dimensions. Use CSS to fit:

#containingDiv { 
  overflow: hidden;
}
#myCanvas {
  position: absolute; 
  top: 0px;
  left: 0px;
} 

The browser window generally won't ever be larger than the screen itself (except where the screen resolution is misreported, as it could be with non-matching dual monitors), so the background won't show and pixel proportions won't vary. The canvas pixels will be directly proportional to the screen resolution unless you use CSS to scale the canvas.

public enum MyEnum
{
    ONE(1),
    TWO(2);

    private int value;

    private MyEnum(int val){
        value = val;
    }

    public int getValue(){
        return value;
    }
}
