This is a solution where you have many fields in your table and don't want to get a finger cramp from typing all the fields, just type the ones needed :)

How to copy some rows into the same table, with some fields having different values:

1. Create a temporary table with all the rows you want to copy
2. Update all the rows in the temporary table with the values you want
3. If you have an auto increment field, you should set it to NULL in the temporary table
4. Copy all the rows of the temporary table into your original table
5. Delete the temporary table

Your code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE Event_ID="155";

UPDATE temporary_table SET Event_ID="120";

UPDATE temporary_table SET ID=NULL

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

General scenario code:

CREATE table temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

UPDATE temporary_table SET <auto_inc_field>=NULL;

INSERT INTO original_table SELECT * FROM temporary_table;

DROP TABLE temporary_table

Simplified/condensed code:

CREATE TEMPORARY TABLE temporary_table AS SELECT * FROM original_table WHERE <conditions>;

UPDATE temporary_table SET <auto_inc_field>=NULL, <fieldx>=<valuex>, <fieldy>=<valuey>, ...;

INSERT INTO original_table SELECT * FROM temporary_table;

As creation of the temporary table uses the TEMPORARY keyword it will be dropped automatically when the session finishes (as @ar34z suggested).

As mentioned above

Application.Current.DispatcherUnhandledException will not catch exceptions that are thrown from another thread then the main thread.

That actual depend on how the thread was created

One case that is not handled by Application.Current.DispatcherUnhandledException is System.Windows.Forms.Timer for which Application.ThreadException can be used to handle these if you run Forms on other threads than the main thread you will need to set Application.ThreadException from each such thread

Ok @Adam and @Kimvais were right, paramiko cannot parse .ppk files.

So the way to go (thanks to @JimB too) is to convert .ppk file to openssh private key format; this can be achieved using Puttygen as described here.

Then it's very simple getting connected with it:

import paramiko
ssh = paramiko.SSHClient()

ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())

ssh.connect('<hostname>', username='<username>', password='<password>', key_filename='<path/to/openssh-private-key-file>')

stdin, stdout, stderr = ssh.exec_command('ls')
print stdout.readlines()
ssh.close()

Apply 100% width and height to your image:

<div style="height:42px;width:42px">
  <img src="http://someimage.jpg" style="width:100%; height:100%">
</div>

This way it will same size of its parent.

In Linux, Open the VIM configuration file

$ sudo -H gedit /etc/vim/vimrc

Added following lines:

set fileencodings=utf-8,ucs-bom,gb18030,gbk,gb2312,cp936
set termencoding=utf-8
set encoding=utf-8

Save and exit, and terminal command:

$ source /etc/vim/vimrc

At this time VIM will correctly display Chinese.

There's a huge difference. break-all is basically unusable for rendering readable text.

Let's say you've got the string This is a text from an old magazine in a container which only fits 6 chars per row.

word-break: break-all

This i
s a te
xt fro
m an o
ld mag
azine

As you can see the result is awful. break-all will try to fit as many chararacters into each row as possible, it will even split a 2 letter word like "is" onto 2 rows! It's ridiculous. This is why break-all is rarely ever used.

word-wrap: break-word

This
is a
text
from
an old
magazi
ne

break-word will only break words which are too long to ever fit the container (like "magazine", which is 8 chars, and the container only fits 6 chars). It will never break words that could fit the container in their entirety, instead it will push them to a new line.

<div style="width: 100px; border: solid 1px black; font-family: monospace;">_x000D_
  <h1 style="word-break: break-all;">This is a text from an old magazine</h1>_x000D_
  <hr>_x000D_
  <h1 style="word-wrap: break-word;">This is a text from an old magazine</h1>_x000D_
</div

To extract STRING, try:

myString = '123STRINGabc'
startString = '123'
endString = 'abc'

mySubString=myString[myString.find(startString)+len(startString):myString.find(endString)]

It is a common misconception that time (a measurable 4th dimension) is different over the world. Timestamp as a moment in time is unique. Date however is influenced how we "see" time but actually it is "time of day".

An example: two people look at the clock at the same moment. The timestamp is the same, right? But one of them is in London and sees 12:00 noon (GMT, timezone offset is 0), and the other is in Belgrade and sees 14:00 (CET, Central Europe, daylight saving now, offset is +2).

Their perception is different but the moment is the same.

You can find more details in this answer.

UPDATE

OK, it's not a duplicate of this question but it is pointless since you are confusing the terms "Timestamp = moment in time (objective)" and "Date[Time] = time of day (subjective)".

Let's look at your original question code broken down like this:

// Get the "original" value from database.
Timestamp momentFromDB = rs.getTimestamp("anytimestampcolumn");

// Turn it into a Joda DateTime with time zone.
DateTime dt = new DateTime(momentFromDB, DateTimeZone.forID("anytimezone"));

// And then turn it back into a timestamp but "with time zone".
Timestamp ts = new Timestamp(dt.getMillis());

I haven't run this code but I am certain it will print true and the same number of milliseconds each time:

System.out.println("momentFromDB == dt : " + (momentFromDB.getTime() == dt.getTimeInMillis());
System.out.println("momentFromDB == ts : " + (momentFromDB.getTime() == ts.getTime()));
System.out.println("dt == ts : " + (dt.getTimeInMillis() == ts.getTime()));

System.out.println("momentFromDB [ms] : " + momentFromDB.getTime());
System.out.println("ts [ms] : " + ts.getTime());
System.out.println("dt [ms] : " + dt.getTimeInMillis());

But as you said yourself printing them out as strings will result in "different" time because DateTime applies the time zone. That's why "time" is stored and transferred as Timestamp objects (which basically wraps a long) and displayed or entered as Date[Time].

In your own answer you are artificially adding an offset and creating a "wrong" time. If you use that timestamp to create another DateTime and print it out it will be offset twice.

// Turn it back into a Joda DateTime with time zone.
DateTime dt = new DateTime(ts, DateTimeZone.forID("anytimezone"));

P.S. If you have the time go through the very complex Joda Time source code to see how it holds the time (millis) and how it prints it.

The Esentutl /y option allows copyng (single) file files with progress bar like this :

the command should look like :

esentutl /y "FILE.EXT" /d "DEST.EXT" /o

The command is available on every windows machine but the y option is presented in windows vista. As it works only with single files does not look very useful for a small ones. Other limitation is that the command cannot overwrite files. Here's a wrapper script that checks the destination and if needed could delete it (help can be seen by passing /h).

You can define a DB class as below. Also, as andrewf suggested, use a context manager for cursor access.I'd define it as a member function. This way it keeps the connection open across multiple transactions from the app code and saves unnecessary reconnections to the server.

You can set a layout manager like BorderLayout and then define more specifically, where your panel should go:

MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new BorderLayout());
mainFrame.add(mainPanel, BorderLayout.CENTER);
mainFrame.pack();
mainFrame.setVisible(true);

This puts the panel into the center area of the frame and lets it grow automatically when resizing the frame.

git checkout -b NEW_BRANCH_NAME COMMIT_ID

This will create a new branch called 'NEW_BRANCH_NAME' and check it out.

("check out" means "to switch to the branch")

git branch NEW_BRANCH_NAME COMMIT_ID

This just creates the new branch without checking it out.

in the comments many people seem to prefer doing this in two steps. here's how to do so in two steps:

git checkout COMMIT_ID
# you are now in the "detached head" state
git checkout -b NEW_BRANCH_NAME

sample

As of v0.20.0, you can use pd.DataFrame.sample, which can be used to return a random sample of a fixed number rows, or a percentage of rows:

df = df.sample(n=k)     # k rows
df = df.sample(frac=k)  # int(len(df.index) * k) rows

For reproducibility, you can specify an integer random_state, equivalent to using np.ramdom.seed. So, instead of setting, for example, np.random.seed = 0, you can:

df = df.sample(n=k, random_state=0)

Use the os.EOL constant instead.

var os = require("os");

function processInput ( text ) 
{     
  fs.open('H://log.txt', 'a', 666, function( e, id ) {
   fs.write( id, text + os.EOL, null, 'utf8', function(){
    fs.close(id, function(){
     console.log('file is updated');
    });
   });
  });
 }

Are you sure you can't get access to request / session scope variables from a JSF page?

This is what I'm doing in our login page, using Spring Security:

<h:outputText
    rendered="#{param.loginFailed == 1 and SPRING_SECURITY_LAST_EXCEPTION != null}">
    <span class="msg-error">#{SPRING_SECURITY_LAST_EXCEPTION.message}</span>
</h:outputText>

dirname "/usr/home/theconjuring/music/song.mp3" will yield /usr/home/theconjuring/music.

I believe that there can still be and valid logic on views. But for this kind of things I agree with @BigMike, it is better placed on the model. Having said that the problem can be solved in three ways:

Your answer (assuming this works, I haven't tried this):

<div class="details @(@Model.Details.Count > 0 ? "show" : "hide")">

Second option:

@if (Model.Details.Count > 0) {
    <div class="details show">
}
else {
    <div class="details hide">
}

Third option:

<div class="@("details " + (Model.Details.Count>0 ? "show" : "hide"))">

In my case it happened for leaving some empty intent-filter inside the Activity tag

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">

            <intent-filter>

            </intent-filter>

    </activity> 

So just removing them solved the problem.

    <activity
            android:name=".MainActivity"
            android:label="@string/app_name"
            android:theme="@style/AppTheme.NoActionBar">
    </activity> 

The 2nd parameter in the get call is a config object. You want something like this:

$http
    .get('accept.php', {
        params: {
            source: link,
            category_id: category
        }
     })
     .success(function (data,status) {
          $scope.info_show = data
     });

See the Arguments section of http://docs.angularjs.org/api/ng.$http for more detail

As you can see, there are two ways to get things done:

• enlist all acceptable options
• exclude all wrong options

Obviously, second way is much more simple (only two cases against four).

Your SQL will look like:

SELECT * FROM Product_sales 
WHERE NOT (From_date > @RangeTill OR To_date < @RangeFrom)

jQuery.fn.ownText = function () {
    return $(this).contents().filter(function () {
        return this.nodeType === Node.TEXT_NODE;
    }).text();
};

The following will help you to give each Platform the styling you want:

import { Text, View, Platform } from 'react-native';

......
<View style={styles.viewClass}></View>
......


const styles = {
viewClass: {
    justifyContent: 'center',
    alignItems: 'center',
    height: 60,
    ...Platform.select({
        ios: {
            shadowColor: '#000',
            shadowOffset: { width: 0, height: 2 },
            shadowOpacity: 0.2,
        },
        android: {
            elevation: 1

        },
      }),
}
};

Another option is to add the M2_HOME variable at: IntelliJ IDEA=>Preferences=>IDE Settings=>Path Variables

After a restart of IntelliJ, IntelliJ IDEA=>Preferences=>Project Settings=>Maven=>Maven home directory should be set to your M2_HOME variable.

The most beautiful answer is... Extend jQuery with this function...

$.fn.extend({
    toggleText: function(a, b){
        return this.text(this.text() == b ? a : b);
    }
});

HTML:

<button class="example"> Initial </button>

Use:

$(".example").toggleText('Initial', 'Secondary');

I've used the logic ( x == b ? a : b ) in the case that the initial HTML text is slightly different (an extra space, period, etc...) so you'll never get a duplicate showing of the intended initial value

(Also why I purposely left spaces in the HTML example ;-)

Another possibility for HTML toggle use brought to my attention by Meules [below] is:

$.fn.extend({
        toggleHtml: function(a, b){
            return this.html(this.html() == b ? a : b);
        }
    });

HTML:

<div>John Doe was an unknown.<button id='readmore_john_doe'> Read More... </button></div>

Use:

$("readmore_john_doe").click($.toggleHtml(
    'Read More...', 
    'Until they found his real name was <strong>Doe John</strong>.')
);

(or something like this)

Converting is simple:

let float = Float(1.1) // 1.1
let int = Int(float) // 1

But it is not safe:

let float = Float(Int.max) + 1
let int = Int(float)

Will due to a nice crash:

fatal error: floating point value can not be converted to Int because it is greater than Int.max

So I've created an extension that handles overflow:

extension Double {
    // If you don't want your code crash on each overflow, use this function that operates on optionals
    // E.g.: Int(Double(Int.max) + 1) will crash:
    // fatal error: floating point value can not be converted to Int because it is greater than Int.max
    func toInt() -> Int? {
        if self > Double(Int.min) && self < Double(Int.max) {
            return Int(self)
        } else {
            return nil
        }
    }
}


extension Float {
    func toInt() -> Int? {
        if self > Float(Int.min) && self < Float(Int.max) {
            return Int(self)
        } else {
            return nil
        }
    }
}

I hope this can help someone

The best solution, where en is the English locale:

fraction.toLocaleString("en", {style: "percent"})

If the button is located between the form tags, I prefer this version:

$('.my-button').click(function (event) {
    var $target = $( event.target );
    $target.closest("form").submit();
});

Using Between condition

SELECT *
FROM TEST
WHERE COLUMN_NAME BETWEEN x AND y ;

Or using Just operators,

SELECT *
FROM TEST
WHERE COLUMN_NAME >= x AND COLUMN_NAME   <= y;

If you have to choose between __repr__ or __str__ go for the first one, as by default implementation __str__ calls __repr__ when it wasn't defined.

Custom Vector3 example:

class Vector3(object):
    def __init__(self, args):
        self.x = args[0]
        self.y = args[1]
        self.z = args[2]

    def __repr__(self):
        return "Vector3([{0},{1},{2}])".format(self.x, self.y, self.z)

    def __str__(self):
        return "x: {0}, y: {1}, z: {2}".format(self.x, self.y, self.z)

In this example, repr returns again a string that can be directly consumed/executed, whereas str is more useful as a debug output.

v = Vector3([1,2,3])
print repr(v)    #Vector3([1,2,3])
print str(v)     #x:1, y:2, z:3

You could use a print stylesheet, but this will affect all print functions.

You could try having a print stylesheet externalally, and it is included via JavaScript when a button is pressed, and then call window.print(), then after that remove it.

You have to modify the viewBox property to change the height and the width correctly with a svg. It is in the <svg> tag of the svg.

Assuming you have the four edges of the rectangle check the distance from the edges to the center of the circle, if its less then the radius, then the shapes are intersecting.

if sqrt((rectangleRight.x - circleCenter.x)^2 +
        (rectangleBottom.y - circleCenter.y)^2) < radius
// then they intersect

if sqrt((rectangleRight.x - circleCenter.x)^2 +
        (rectangleTop.y - circleCenter.y)^2) < radius
// then they intersect

if sqrt((rectangleLeft.x - circleCenter.x)^2 +
        (rectangleTop.y - circleCenter.y)^2) < radius
// then they intersect

if sqrt((rectangleLeft.x - circleCenter.x)^2 +
        (rectangleBottom.y - circleCenter.y)^2) < radius
// then they intersect

Just set the value of cookie to false in order to unset it,

setcookie('cookiename', false);

PS:- That's the easiest way to do it.

My solution is basically the same as dickoa's but a little easier to interpret:

data(mtcars)
n = nrow(mtcars)
trainIndex = sample(1:n, size = round(0.7*n), replace=FALSE)
train = mtcars[trainIndex ,]
test = mtcars[-trainIndex ,]

Say P7 is a Cell then you can use the following Syntex to check the value of the cell and assign appropriate value to another cell based on this following nested if:

=IF(P7=0,200,IF(P7=1,100,IF(P7=2,25,IF(P7=3,10,IF((P7=4),5,0)))))

Yes if you are using Python 3.3+. You can use the built-in unittest.mock to assert method called. For Python 2.6+ use the rolling backport Mock, which is the same thing.

Here is a quick example in your case:

from unittest.mock import MagicMock
aw = aps.Request("nv1")
aw.Clear = MagicMock()
aw2 = aps.Request("nv2", aw)
assert aw.Clear.called

Use Date object:

var time = Date.parse('02.02.1999');
document.writeln(time);

Give: 917902800000

I went through most of the solutions posted on this thread. While this question might be old, it is still very applicable to new projects even now, so I spent quite a lot of time reading up on the answers presented here as well as else where.

As @Marco pointed out the different cases under which a 404 can happen, I checked the solution I compiled together against that list. In addition to his list of requirements, I also added one more.

• The solution should be able to handle MVC as well as AJAX/WebAPI calls in the most appropriate manner. (i.e. if 404 happens in MVC, it should show the Not Found page and if 404 happens in WebAPI, it should not hijack the XML/JSON response so that the consuming Javascript can parse it easily).

This solution is 2 fold:

First part of it comes from @Guillaume at https://stackoverflow.com/a/27354140/2310818. Their solution takes care of any 404 that were caused due to invalid route, invalid controller and invalid action.

The idea is to create a WebForm and then make it call the NotFound action of your MVC Errors Controller. It does all of this without any redirect so you will not see a single 302 in Fiddler. The original URL is also preserved, which makes this solution fantastic!

Second part of it comes from @Germán at https://stackoverflow.com/a/5536676/2310818. Their solution takes care of any 404 returned by your actions in the form of HttpNotFoundResult() or throw new HttpException()!

The idea is to have a filter look at the response as well as the exception thrown by your MVC controllers and to call the appropriate action in your Errors Controller. Again this solution works without any redirect and the original url is preserved!

As you can see, both of these solutions together offer a very robust error handling mechanism and they achieve all the requirements listed by @Marco as well as my requirements. If you would like to see a working sample or a demo of this solution, please leave in the comments and I would be happy to put it together.

After some tinkering for a while with different solutions i found out that one must create a notification channel in Android 8.1 and above.

private fun startForeground() {
    val channelId =
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
                createNotificationChannel("my_service", "My Background Service")
            } else {
                // If earlier version channel ID is not used
                // https://developer.android.com/reference/android/support/v4/app/NotificationCompat.Builder.html#NotificationCompat.Builder(android.content.Context)
                ""
            }

    val notificationBuilder = NotificationCompat.Builder(this, channelId )
    val notification = notificationBuilder.setOngoing(true)
            .setSmallIcon(R.mipmap.ic_launcher)
            .setPriority(PRIORITY_MIN)
            .setCategory(Notification.CATEGORY_SERVICE)
            .build()
    startForeground(101, notification)
}

@RequiresApi(Build.VERSION_CODES.O)
private fun createNotificationChannel(channelId: String, channelName: String): String{
    val chan = NotificationChannel(channelId,
            channelName, NotificationManager.IMPORTANCE_NONE)
    chan.lightColor = Color.BLUE
    chan.lockscreenVisibility = Notification.VISIBILITY_PRIVATE
    val service = getSystemService(Context.NOTIFICATION_SERVICE) as NotificationManager
    service.createNotificationChannel(chan)
    return channelId
}

From my understanding background services are now displayed as normal notifications that the user then can select to not show by deselecting the notification channel.

Update: Also don't forget to add the foreground permission as required Android P:

<uses-permission android:name="android.permission.FOREGROUND_SERVICE" />

a fresh answer to a very old question:

starting from python 3.2 you can do this:

import os
path = '/home/dail/first/second/third'
os.makedirs(path, exist_ok=True)

thanks to the exist_ok flag this will not even complain if the directory exists (depending on your needs....).

starting from python 3.4 (which includes the pathlib module) you can do this:

from pathlib import Path
path = Path('/home/dail/first/second/third')
path.mkdir(parents=True)

starting from python 3.5 mkdir also has an exist_ok flag - setting it to True will raise no exception if the directory exists:

path.mkdir(parents=True, exist_ok=True)

Given your comment to the question (where you say that executing the install for a single package works as expected), I would suggest looping over your requirement file. In bash:

#!/bin/sh
while read p; do
  pip install $p
done < requirements.pip

HTH!

You should use labels attribute inside plot function and the value of this attribute should be the vector containing the values that you want for each point to have.

I am assuming you have site key and secret in place. Follow this step.

In your HTML file, add the script.

 <script src="https://www.google.com/recaptcha/api.js?render=put your site key here"></script>

Also, do use jQuery for easy event handling.

Here is the simple form.

 <form id="comment_form" action="form.php" method="post" >
      <input type="email" name="email" placeholder="Type your email" size="40"><br><br>
      <textarea name="comment" rows="8" cols="39"></textarea><br><br>
      <input type="submit" name="submit" value="Post comment"><br><br>
    </form>

You need to initialize the Google recaptcha and listen for the ready event. Here is how to do that.

     <script>
       // when form is submit
    $('#comment_form').submit(function() {
        // we stoped it
        event.preventDefault();
        var email = $('#email').val();
        var comment = $("#comment").val();
        // needs for recaptacha ready
        grecaptcha.ready(function() {
            // do request for recaptcha token
            // response is promise with passed token
            grecaptcha.execute('put your site key here', {action: 'create_comment'}).then(function(token) {
                // add token to form
                $('#comment_form').prepend('<input type="hidden" name="g-recaptcha-response" value="' + token + '">');
                $.post("form.php",{email: email, comment: comment, token: token}, function(result) {
                        console.log(result);
                        if(result.success) {
                                alert('Thanks for posting comment.')
                        } else {
                                alert('You are spammer ! Get the @$%K out.')
                        }
                });
            });
        });
  });
  </script>

Here is the sample PHP file. You can use Servlet or Node or any backend language in place of it.

<?php

        $email;$comment;$captcha;
        if(isset($_POST['email'])){
          $email=$_POST['email'];
        }if(isset($_POST['comment'])){
          $comment=$_POST['comment'];
        }if(isset($_POST['token'])){
          $captcha=$_POST['token'];
          }
        if(!$captcha){
          echo '<h2>Please check the the captcha form.</h2>';
          exit;
        }
        $secretKey = "put your secret key here";
        $ip = $_SERVER['REMOTE_ADDR'];

        // post request to server

        $url =  'https://www.google.com/recaptcha/api/siteverify?secret=' . urlencode($secretKey) .  '&response=' . urlencode($captcha);
        $response = file_get_contents($url);
        $responseKeys = json_decode($response,true);
        header('Content-type: application/json');
        if($responseKeys["success"]) {
                echo json_encode(array('success' => 'true'));
        } else {
                echo json_encode(array('success' => 'false'));
        }
?>

Hope it helps.

While there is no iterator reset, the "itertools" module from python 2.6 (and later) has some utilities that can help there. One of then is the "tee" which can make multiple copies of an iterator, and cache the results of the one running ahead, so that these results are used on the copies. I will seve your purposes:

>>> def printiter(n):
...   for i in xrange(n):
...     print "iterating value %d" % i
...     yield i

>>> from itertools import tee
>>> a, b = tee(printiter(5), 2)
>>> list(a)
iterating value 0
iterating value 1
iterating value 2
iterating value 3
iterating value 4
[0, 1, 2, 3, 4]
>>> list(b)
[0, 1, 2, 3, 4]

You can pass arguments to a gnuplot script since version 5.0, with the flag -c. These arguments are accessed through the variables ARG0 to ARG9, ARG0 being the script, and ARG1 to ARG9 string variables. The number of arguments is given by ARGC.

For example, the following script ("script.gp")

#!/usr/local/bin/gnuplot --persist

THIRD=ARG3
print "script name        : ", ARG0
print "first argument     : ", ARG1
print "third argument     : ", THIRD 
print "number of arguments: ", ARGC 

can be called as:

$ gnuplot -c script.gp one two three four five
script name        : script.gp
first argument     : one
third argument     : three
number of arguments: 5

or within gnuplot as

gnuplot> call 'script.gp' one two three four five
script name        : script.gp
first argument     : one
third argument     : three
number of arguments: 5

In gnuplot 4.6.6 and earlier, there exists a call mechanism with a different (now deprecated) syntax. The arguments are accessed through $#, $0,...,$9. For example, the same script above looks like:

#!/usr/bin/gnuplot --persist

THIRD="$2"
print "first argument     : ", "$0"
print "second argument    : ", "$1"
print "third argument     : ", THIRD
print "number of arguments: ", "$#"

and it is called within gnuplot as (remember, version <4.6.6)

gnuplot> call 'script4.gp' one two three four five
first argument     : one
second argument    : two
third argument     : three
number of arguments: 5

Notice there is no variable for the script name, so $0 is the first argument, and the variables are called within quotes. There is no way to use this directly from the command line, only through tricks as the one suggested by @con-fu-se.

The easiest way is this.

byte[] bytes = rs.getBytes("my_field");

Python supports a "bignum" integer type which can work with arbitrarily large numbers. In Python 2.5+, this type is called long and is separate from the int type, but the interpreter will automatically use whichever is more appropriate. In Python 3.0+, the int type has been dropped completely.

That's just an implementation detail, though — as long as you have version 2.5 or better, just perform standard math operations and any number which exceeds the boundaries of 32-bit math will be automatically (and transparently) converted to a bignum.

You can find all the gory details in PEP 0237.

If your source folder is structured /go/src/blog (assuming the name of your source folder is blog).

1. cd /go/src/blog ... (cd inside the folder that has your package)
2. go install
3. blog

That should run all of your files at the same time, instead of you having to list the files manually or "bashing" a method on the command line.

For common edit operations I prefer to install vi (vim-tiny), which uses only 1491 kB or nano which uses 1707 kB.

In other hand vim uses 28.9 MB.

We have to remember that in order for apt-get install to work, we have to do the update the first time, so:

apt-get update
apt-get install vim-tiny

To start the editor in CLI we need to enter vi.

You can do it using FullscreenVideoView class. Its a small library project. It's video progress dialog is build in. it's gradle is :

compile 'com.github.rtoshiro.fullscreenvideoview:fullscreenvideoview:1.1.0'

your VideoView xml is like this

<com.github.rtoshiro.view.video.FullscreenVideoLayout
        android:id="@+id/videoview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

In your activity , initialize it using this way:

    FullscreenVideoLayout videoLayout;

videoLayout = (FullscreenVideoLayout) findViewById(R.id.videoview);
        videoLayout.setActivity(this);

        Uri videoUri = Uri.parse("YOUR_VIDEO_URL");
        try {
            videoLayout.setVideoURI(videoUri);

        } catch (IOException e) {
            e.printStackTrace();
        }

That's it. Happy coding :)

1-Delete the migration file. 2-connect to your database and drop the table created by the migration. 3-recreate the file of the migration with the the right sql.

First of all, there's no such thing as a JSON object. What you've got in your question is a JavaScript object literal (see here for a great discussion on the difference). Here's how you would go about serializing what you've got to JSON though:

I would use an anonymous type filled with your results type:

string json = JsonConvert.SerializeObject(new
{
    results = new List<Result>()
    {
        new Result { id = 1, value = "ABC", info = "ABC" },
        new Result { id = 2, value = "JKL", info = "JKL" }
    }
});

Also, note that the generated JSON has result items with ids of type Number instead of strings. I doubt this will be a problem, but it would be easy enough to change the type of id to string in the C#.

I'd also tweak your results type and get rid of the backing fields:

public class Result
{
    public int id { get ;set; }
    public string value { get; set; }
    public string info { get; set; }
}

Furthermore, classes conventionally are PascalCased and not camelCased.

Here's the generated JSON from the code above:

{
  "results": [
    {
      "id": 1,
      "value": "ABC",
      "info": "ABC"
    },
    {
      "id": 2,
      "value": "JKL",
      "info": "JKL"
    }
  ]
}

You want the 'change' event handler, instead of 'click'.

$('#mySelect').change(function(){ 
    var value = $(this).val();
});

try next:

label[for="userName"] {_x000D_
  position: relative;_x000D_
}_x000D_
_x000D_
label[for="userName"]::after {_x000D_
  content: '[after]';_x000D_
  width: 22px;_x000D_
  height: 22px;_x000D_
  display: inline-block;_x000D_
  position: absolute;_x000D_
  right: -30px;_x000D_
}

<label for="userName">_x000D_
 Name: _x000D_
 <input type="text" name="userName" id="userName">_x000D_
 </label>

mysqli_report(MYSQLI_REPORT_ERROR | MYSQLI_REPORT_STRICT);

I am not sure if there is a mysql version of this but adding this line of code allows throwing mysqli_sql_exception.
I know, passed a lot of time and the question is already checked answered but I got a different answer and it may be helpful.

Another trigger for this error is leaving the "." out before your "otherwise" or any other route in your route definition:

  app.config(['$routeProvider',
     function($routeProvider) {
        $routeProvider.
           when('/view1', {
              templateUrl: 'partials/view1.html',
              controller: 'Ctrl1'
           }).
           otherwise({
              redirectTo: '/viewCounts'
           });
     }]);

Mortified by a full-stop, yet again. Gotta love JS!

It depends on what you want to do. This code swaps two elements of an array.

void swap(int i, int j, int[] arr) {
  int t = arr[i];
  arr[i] = arr[j];
  arr[j] = t;
}

Something like this swaps the content of two int[] of equal length.

void swap(int[] arr1, int[] arr2) {
  int[] t = arr1.clone();
  System.arraycopy(arr2, 0, arr1, 0, t.length);
  System.arraycopy(t, 0, arr2, 0, t.length);
}

Something like this swaps the content of two BitSet (using the XOR swap algorithm):

void swap(BitSet s1, BitSet s2) {
  s1.xor(s2);
  s2.xor(s1);
  s1.xor(s2);
}

Something like this swaps the x and y fields of some Point class:

void swapXY(Point p) {
  int t = p.x;
  p.x = p.y;
  p.y = t;
}

This will get just the revision number of the last changed revision:

<?php
$REV="";
$repo = ""; #url or directory
$REV = svn info $repo --show-item last-changed-revision;
?>

I hope this helps.

When you visited https://localhost previously at some point it not only visited this over a secure channel (https rather than http), it also told your browser, using a special HTTP header: Strict-Transport-Security (often abbreviated to HSTS), that it should ONLY use https for all future visits.

This is a security feature web servers can use to prevent people being downgraded to http (either intentionally or by some evil party).

However if you then then turn off your https server, and just want to browse http you can't (by design - that's the point of this security feature).

HSTS also does prevents you from accepting and skipping past certificate errors.

To reset this, so HSTS is no longer set for localhost, type the following in your Chrome address bar:

chrome://net-internals/#hsts

Where you will be able to delete this setting for "localhost".

You might also want to find out what was setting this to avoid this problem in future!

Note that for other sites (e.g. www.google.com) these are "preloaded" into the Chrome code and so cannot be removed. When you query them at chrome://net-internals/#hsts you will see them listed as static HSTS entries.

And finally note that Google has started preloading HSTS for the entire .dev domain: https://ma.ttias.be/chrome-force-dev-domains-https-via-preloaded-hsts/

in my case, datas is an objects of Array for more information please Click Here

<% for(let [index,data] of datas.entries() || []){  %>
 Index : <%=index%>
 Data : <%=data%>
<%} %>

I generally like to use my own extension for that:

string data = "THExxQUICKxxBROWNxxFOX";
var dataspt = data.Split("xx");
//>THE  QUICK  BROWN  FOX 


//the extension class must be declared as static
public static class StringExtension
{   
    public static string[] Split(this string str, string splitter)
    {
        return str.Split(new[] { splitter }, StringSplitOptions.None);
    }
}

This will however lead to an Exception, if Microsoft decides to include this method-overload in later versions. It is also the likely reason why Microsoft has not included this method in the meantime: At least one company I worked for, used such an extension in all their C# projects.

It may also be possible to conditionally define the method at runtime if it doesn't exist.

In response to comments on rexem's answer, with respect to whether a an inline view or CTE would be faster I recast the queries to use a table I, and everyone, had available: sys.objects.

WITH object_rows AS (
    SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects)
SELECT object_id
FROM object_rows
WHERE RN > 1

SELECT object_id
FROM (SELECT object_id, 
        ROW_NUMBER() OVER ( ORDER BY object_id) RN
    FROM sys.objects) T
WHERE RN > 1

The query plans produced were exactly the same. I would expect in all cases, the query optimizer would come up with the same plan, at least in simple replacement of CTE with inline view or vice versa.

Of course, try your own queries on your own system to see if there is a difference.

Also, row_number() in the where clause is a common error in answers given on Stack Overflow. Logicaly row_number() is not available until the select clause is processed. People forget that and when they answer without testing the answer, the answer is sometimes wrong. (A charge I have myself been guilty of.)

2 things to understand here -

1) If you are casting Primitive interger to Primitive double . It works. e.g. It works fine.

int pri=12; System.out.println((double)pri);

2) if you try to Cast Integer object to Double object or vice - versa , It fails.

Integer a = 1; Double b = (double) a; // WRONG. Fails with class cast excptn

Solution -

Soln 1) Integer i = 1; Double b = new Double(i);
soln 2) Double d = 2.0; Integer x = d.intValue();

What about:

#region Using Statements
using System;
using System.Xml;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XmlDocument doc = new XmlDocument( );

        //(1) the xml declaration is recommended, but not mandatory
        XmlDeclaration xmlDeclaration = doc.CreateXmlDeclaration( "1.0", "UTF-8", null );
        XmlElement root = doc.DocumentElement;
        doc.InsertBefore( xmlDeclaration, root );

        //(2) string.Empty makes cleaner code
        XmlElement element1 = doc.CreateElement( string.Empty, "body", string.Empty );
        doc.AppendChild( element1 );

        XmlElement element2 = doc.CreateElement( string.Empty, "level1", string.Empty );
        element1.AppendChild( element2 );

        XmlElement element3 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text1 = doc.CreateTextNode( "text" );
        element3.AppendChild( text1 );
        element2.AppendChild( element3 );

        XmlElement element4 = doc.CreateElement( string.Empty, "level2", string.Empty );
        XmlText text2 = doc.CreateTextNode( "other text" );
        element4.AppendChild( text2 );
        element2.AppendChild( element4 );

        doc.Save( "D:\\document.xml" );
    }
}

_{(1) Does a valid XML file require an xml declaration?
(2) What is the difference between String.Empty and “” (empty string)?}

The result is:

<?xml version="1.0" encoding="UTF-8"?>
<body>
  <level1>
    <level2>text</level2>
    <level2>other text</level2>
  </level1>
</body>

But I recommend you to use LINQ to XML which is simpler and more readable like here:

#region Using Statements
using System;
using System.Xml.Linq;
#endregion 

class Program {
    static void Main( string[ ] args ) {
        XDocument doc = new XDocument( new XElement( "body", 
                                           new XElement( "level1", 
                                               new XElement( "level2", "text" ), 
                                               new XElement( "level2", "other text" ) ) ) );
        doc.Save( "D:\\document.xml" );
    }
}

For UTF 8 Conversion and Currency Symbol Export Use this:

var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><?xml version="1.0" encoding="UTF-8" standalone="yes"?><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
      if (!table.nodeType) table = document.getElementById(table)
      var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
    window.location.href = uri + base64(format(template, ctx))
  }
})()

Intellisense does work for C# 6, and it's great.

For running console apps you should set up some additional tools:

• ASP.NET 5; in Powershell: &{$Branch='dev';iex ((new-object net.webclient).DownloadString('https://raw.githubusercontent.com/aspnet/Home/dev/dnvminstall.ps1'))}
• Node.js including package manager npm.
• The rest of required tools including Yeoman yo: npm install -g yo grunt-cli generator-aspnet bower
• You should also invoke .NET Version Manager: c:\Users\Username\.dnx\bin\dnvm.cmd upgrade -u

Then you can use yo as wizard for Console Application: yo aspnet Choose name and project type. After that go to created folder cd ./MyNewConsoleApp/ and run dnu restore

To execute your program just type >run in Command Palette (Ctrl+Shift+P), or execute dnx . run in shell from the directory of your project.

If the elapsed event takes longer then the interval, it will create another thread to raise the elapsed event. But there is a workaround for this

static void timer_Elapsed(object sender, ElapsedEventArgs e)    
{     
   try
   {
      timer.Stop(); 
      Thread.Sleep(2000);        
      Debug.WriteLine(Thread.CurrentThread.ManagedThreadId);    
   }
   finally
   {
     timer.Start();
   }
}

Make sure first that you have certificates installed on your Debian in /etc/ssl/certs.

If not, reinstall them:

sudo apt-get install --reinstall ca-certificates

Since that package does not include root certificates, add:

sudo mkdir /usr/local/share/ca-certificates/cacert.org
sudo wget -P /usr/local/share/ca-certificates/cacert.org http://www.cacert.org/certs/root.crt http://www.cacert.org/certs/class3.crt
sudo update-ca-certificates

Make sure your git does reference those CA:

git config --global http.sslCAinfo /etc/ssl/certs/ca-certificates.crt

Jason C mentions another potential cause (in the comments):

It was the clock. The NTP server was down, the system clock wasn't set properly, I didn't notice or think to check initially, and the incorrect time was causing verification to fail.

Certificates are time sensitive.

The answer to your question is that the newer SQLite 3 has improved performance, use that.

This answer Why is SQLAlchemy insert with sqlite 25 times slower than using sqlite3 directly? by SqlAlchemy Orm Author has 100k inserts in 0.5 sec, and I have seen similar results with python-sqlite and SqlAlchemy. Which leads me to believe that performance has improved with SQLite 3.

It's currently working, I've just changed the operator > in order to work in the snippet, take a look:

window.onload = function() {_x000D_
_x000D_
  if (window.location.href.indexOf("test") <= -1) {_x000D_
    var search_span = document.getElementsByClassName("securitySearchQuery");_x000D_
    search_span[0].style.color = "blue";_x000D_
    search_span[0].style.fontWeight = "bold";_x000D_
    search_span[0].style.fontSize = "40px";_x000D_
_x000D_
  }_x000D_
_x000D_
}

<h1 class="keyword-title">Search results for<span class="securitySearchQuery"> "hi".</span></h1>

With neuraxle, you can easily solve this :

p = Pipeline([
   # expected outputs shape: (n, 1)
   OutputTransformerWrapper(NumpyRavel()), 
   # expected outputs shape: (n, )
   RandomForestRegressor(**RF_tuned_parameters)
])

p, outputs = p.fit_transform(data_inputs, expected_outputs)

Neuraxle is a sklearn-like framework for hyperparameter tuning and AutoML in deep learning projects !

It's not possible to do that using JPA annotation. And this make sense: where a UniqueConstraint clearly define a business rules, an index is just a way to make search faster. So this should really be done by a DBA.

"We usually put ' (space)' after the first sentence before a new line, but it doesn't work in Jupyter."

That inspired me to try using two spaces instead of just one - and it worked!!

(Of course, that functionality could possibly have been introduced between when the question was asked in January 2017, and when my answer was posted in March 2018.)

There are a few steps you need to take to properly store this information in your localStorage. Before we get down to the code however, please note that localStorage (at the current time) cannot hold any data type except for strings. You will need to serialize the array for storage and then parse it back out to make modifications to it.

Step 1:

The First code snippet below should only be run if you are not already storing a serialized array in your localStorage session variable.
To ensure your localStorage is setup properly and storing an array, run the following code snippet first:

var a = [];
a.push(JSON.parse(localStorage.getItem('session')));
localStorage.setItem('session', JSON.stringify(a));

The above code should only be run once and only if you are not already storing an array in your localStorage session variable. If you are already doing this skip to step 2.

Step 2:

Modify your function like so:

function SaveDataToLocalStorage(data)
{
    var a = [];
    // Parse the serialized data back into an aray of objects
    a = JSON.parse(localStorage.getItem('session')) || [];
    // Push the new data (whether it be an object or anything else) onto the array
    a.push(data);
    // Alert the array value
    alert(a);  // Should be something like [Object array]
    // Re-serialize the array back into a string and store it in localStorage
    localStorage.setItem('session', JSON.stringify(a));
}

This should take care of the rest for you. When you parse it out, it will become an array of objects.

Hope this helps.

There are many good answers here. But if you tried all of them and still getting squares instead fontawesome icons, check your css rules. In my case I had the following rule:

* {
  font-family: Roboto-Light, Roboto, 'Helvetica Neue', sans-serif !important;
}

And it overrides fontawesome fonts. Just replacing * selector to body solved my problem:

body {
  font-family: Roboto-Light, Roboto, 'Helvetica Neue', sans-serif !important;
}

public int GetResult(List<int> list){
int first = list.First();
return list.All(x => x == first) ? first : SOME_OTHER_VALUE;
}

In IIS7 with integrated mode, Current is not available in Application_Start. There is a similar thread here.

An API is ready-made source code library.

In Java for example APIs are a set of related classes and interfaces that come in packages. This picture illustrates the libraries included in the Java Standard Edition API. Packages are denoted by their color.

implements means a behaviour will be defined for abstract methods (except for abstract classes obviously), you define the implementation.

extends means that a behaviour is inherited.

With interfaces it is possible to say that one interface should have that the same behaviour as another, there is not even an actual implementation. That's why it makes more sense for an interface to extends another interface instead of implementing it.

On a side note, remember that even if an abstract class can define abstract methods (the sane way an interface does), it is still a class and still has to be inherited (extended) and not implemented.

This is more the Angular way to do it: http://plnkr.co/edit/xYNX47EsYvl4aRuGZmvo?p=preview

1. I added $scope.selectedItem that gets you past your first problem (defaulting the image)
2. I added $scope.setSelectedItem and called it in ng-click. Your final requirements may be different, but using a directive to bind click and change src was overkill, since most of it can be handled with template
3. Notice use of ngSrc to avoid errant server calls on initial load
4. You'll need to adjust some styles to get the image positioned right in the div. If you really need to use background-image, then you'll need a directive like ngSrc that defers setting the background-image style until after real data has loaded.

EDIT Ignore this answer. There are now better answers. See the comments. Use + theme_classic()

EDIT

This is a better version. The bug mentioned below in the original post remains (I think). But the axis line is drawn under the panel. Therefore, remove both the panel.border and panel.background to see the axis lines.

library(ggplot2)
a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

ggplot(df, aes(x = a, y = b)) + geom_point() +
  theme_bw() +
  theme(axis.line = element_line(colour = "black"),
    panel.grid.major = element_blank(),
    panel.grid.minor = element_blank(),
    panel.border = element_blank(),
    panel.background = element_blank()) 

Original post This gets close. There was a bug with axis.line not working on the y-axis (see here), that appears not to be fixed yet. Therefore, after removing the panel border, the y-axis has to be drawn in separately using geom_vline.

library(ggplot2)
library(grid)

a <- seq(1,20)
b <- a^0.25
df <- as.data.frame(cbind(a,b))

p = ggplot(df, aes(x = a, y = b)) + geom_point() +
   scale_y_continuous(expand = c(0,0)) +
   scale_x_continuous(expand = c(0,0)) +
   theme_bw() +
   opts(axis.line = theme_segment(colour = "black"),
        panel.grid.major = theme_blank(),
        panel.grid.minor = theme_blank(),
        panel.border = theme_blank()) +
    geom_vline(xintercept = 0)
p

The extreme points are clipped, but the clipping can be undone using code by baptiste.

gt <- ggplot_gtable(ggplot_build(p))
gt$layout$clip[gt$layout$name=="panel"] <- "off"
grid.draw(gt)

Or use limits to move the boundaries of the panel.

ggplot(df, aes(x = a, y = b)) + geom_point() +
   xlim(0,22) +  ylim(.95, 2.1) +
   scale_x_continuous(expand = c(0,0), limits = c(0,22)) +
   scale_y_continuous(expand = c(0,0), limits = c(.95, 2.2)) +   
   theme_bw() +
   opts(axis.line = theme_segment(colour = "black"),
        panel.grid.major = theme_blank(),
        panel.grid.minor = theme_blank(),
        panel.border = theme_blank()) +
    geom_vline(xintercept = 0)

When you type exit in the command line, it finds the variable with that name and calls __repr__ (or __str__) on it. Usually, you'd get a result like:

<function exit at 0x00B97FB0>

But they decided to redefine that function for the exit object to display a helpful message instead. Whether or not that's a stupid behavior or not, is a subjective question, but one possible reason why it doesn't "just exit" is:

Suppose you're looking at some code in a debugger, for instance, and one of the objects references the exit function. When the debugger tries to call __repr__ on that object to display that function to you, the program suddenly stops! That would be really unexpected, and the measures to counter that might complicate things further (for instance, even if you limit that behavior to the command line, what if you try to print some object that have exit as an attribute?)

Google is returning a very useful error message, which helps to correct the issue!

I think your first line would actually work but I think you need four quotation marks for a string containing a single one (in VB at least):

s = s.Replace("""", "")

for C# you'd have to escape the quotation mark using a backslash:

s = s.Replace("\"", "");

How about pass?

You have to set LANG as well, look for files named 'sp1*.msb', and set for instance export LANG=us if you find a file name sp1us.msb. The error message could sure be better :)

I encountered the same problem in the code and What I did is I found out all the changes I have made from the last correct compilation. And I have observed one function declaration was without ";" and also it was passing a value and I have declared it to pass nothing "void". this method will surely solve the problem for many.

While both reducebykey and groupbykey will produce the same answer, the reduceByKey example works much better on a large dataset. That's because Spark knows it can combine output with a common key on each partition before shuffling the data.

On the other hand, when calling groupByKey - all the key-value pairs are shuffled around. This is a lot of unnessary data to being transferred over the network.

for more detailed check this below link

https://databricks.gitbooks.io/databricks-spark-knowledge-base/content/best_practices/prefer_reducebykey_over_groupbykey.html

Based on @AmNaN suggestion (more details):

class ApplicationController < ActionController::Base

 def current_controller?(names)
  names.include?(params[:controller]) unless params[:controller].blank? || false
 end

 helper_method :current_controller?

end

Now you can call it e.g. in a navigation layout for marking list items as active:

<ul class="nav nav-tabs">
  <li role="presentation" class="<%= current_controller?('items') ? 'active' : '' %>">
    <%= link_to user_items_path(current_user) do %>
      <i class="fa fa-cloud-upload"></i>
    <% end %>
  </li>
  <li role="presentation" class="<%= current_controller?('users') ? 'active' : '' %>">
    <%= link_to users_path do %>
      <i class="fa fa-newspaper-o"></i>
    <% end %>
  </li>
  <li role="presentation" class="<%= current_controller?('alerts') ? 'active' : '' %>">
    <%= link_to alerts_path do %>
      <i class="fa fa-bell-o"></i>
    <% end %>
  </li>
</ul>

For the users and alerts routes, current_page? would be enough:

 current_page?(users_path)
 current_page?(alerts_path)

But with nested routes and request for all actions of a controller (comparable with items), current_controller? was the better method for me:

 resources :users do 
  resources :items
 end

The first menu entry is that way active for the following routes:

   /users/x/items        #index
   /users/x/items/x      #show
   /users/x/items/new    #new
   /users/x/items/x/edit #edit

The most likely explanation is that either a file called 'pandas.py' is in the same directory as your script, or that another variable called 'pd' is used in your program.

Ran into this recently myself on mac, had to remove the ng folder from /usr/local/bin. Was so long ago that I installed the Angular CLI, I'm not entirely sure how I installed it originally.

what's the problem with:

field like "*AA*" and field not like "*BB*"

it should be working.

Could you post some example of your data?

Don't use == use .equals.

try this instead (IIRC, ZipCode needs to implement Comparable for this to work.

boolean unique;
Set<ZipCode> s = new TreeSet<ZipCode>();
for( ZipCode zc : zipcodelist )
    unique||=s.add(zc);
duplicates = !unique;

You can clean up a zombie process by killing its parent process with the following command:

I got the same issue when adding @angular/flex-layout to my Angular 8 project now with

`npm install @angular/flex-layout --save`.

This since now that command installed the major 9th version of the flex-layout package. Instead of upgrading everything else to the last version, I solved it by installing the last 8th major version of the package instead.

 npm install @angular/[email protected] --save

It is very inefficient to store all values in memory, so the objects are reused and loaded one at a time. See this other SO question for a good explanation. Summary:

[...] when looping through the Iterable value list, each Object instance is re-used, so it only keeps one instance around at a given time.

I want to add to other answers that setters can be used to prevent putting the object in an invalid state.

For instance let's suppose that I've to set a TaxId, modelled as a String. The first version of the setter can be as follows:

private String taxId;

public void setTaxId(String taxId) {
    this.taxId = taxId;
}

However we'd better prevent the use to set the object with an invalid taxId, so we can introduce a check:

private String taxId;

public void setTaxId(String taxId) throws IllegalArgumentException {
    if (isTaxIdValid(taxId)) {
        throw new IllegalArgumentException("Tax Id '" + taxId + "' is invalid");
    }
    this.taxId = taxId;
}

The next step, to improve the modularity of the program, is to make the TaxId itself as an Object, able to check itself.

private final TaxId taxId = new TaxId()

public void setTaxId(String taxIdString) throws IllegalArgumentException {
    taxId.set(taxIdString); //will throw exception if not valid
}

Similarly for the getter, what if we don't have a value yet? Maybe we want to have a different path, we could say:

public String getTaxId() throws IllegalStateException {
    return taxId.get(); //will throw exception if not set
}

One of the answers in this question might help you. There seems to be a platform agnostic version for python, but I haven't tried it yet.

    final int[] positions=new int[2]; 
    Spinner sp=findViewByID(R.id.spinner);

    sp.setOnItemSelectedListener(new AdapterView.OnItemSelectedListener() {

        @Override
        public void onItemSelected(AdapterView<?> arg0, View arg1,
                int arg2, long arg3) {
            // TODO Auto-generated method stub
            Toast.makeText( arg2....);
        }

        @Override
        public void onNothingSelected(AdapterView<?> arg0) {
            // TODO Auto-generated method stub

        }
    });

It seems that you have invalid JSON. In that case, that's totally dependent on the data the server sends you which you have not shown. I would suggest running the response through a JSON validator.

While working with Spring Boot application, it is difficult to get the classpath resources using resource.getFile() when it is deployed as JAR as I faced the same issue. This scan be resolved using Stream which will find out all the resources which are placed anywhere in classpath.

Below is the code snippet for the same -

ClassPathResource classPathResource = new ClassPathResource("fileName");
InputStream inputStream = classPathResource.getInputStream();
content = IOUtils.toString(inputStream);

If you are given this format it takes like a link to another page or another link.partial view majorly used for renduring the html files from one place to another.

Each type of integer has a different range of storage capacity

   Type      Capacity

   Int16 -- (-32,768 to +32,767)

   Int32 -- (-2,147,483,648 to +2,147,483,647)

   Int64 -- (-9,223,372,036,854,775,808 to +9,223,372,036,854,775,807)

As stated by James Sutherland in his answer:

int and Int32 are indeed synonymous; int will be a little more familiar looking, Int32 makes the 32-bitness more explicit to those reading your code. I would be inclined to use int where I just need 'an integer', Int32 where the size is important (cryptographic code, structures) so future maintainers will know it's safe to enlarge an int if appropriate, but should take care changing Int32 variables in the same way.

The resulting code will be identical: the difference is purely one of readability or code appearance.

There are a few methods to get metadata about a table:

EXEC sp_help tablename

Will return several result sets, describing the table, it's columns and constraints.

The INFORMATION_SCHEMA views will give you the information you want, though unfortunately you have to query the views and join them manually.

All answers are great, but they are talking about adding extension method to a specific type of enum.

What if you want to add a method to all enums like returning an int of current value instead of explicit casting?

public static class EnumExtensions
{
    public static int ToInt<T>(this T soure) where T : IConvertible//enum
    {
        if (!typeof(T).IsEnum)
            throw new ArgumentException("T must be an enumerated type");

        return (int) (IConvertible) soure;
    }

    //ShawnFeatherly funtion (above answer) but as extention method
    public static int Count<T>(this T soure) where T : IConvertible//enum
    {
        if (!typeof(T).IsEnum)
            throw new ArgumentException("T must be an enumerated type");

        return Enum.GetNames(typeof(T)).Length;
    }
}

The trick behind IConvertible is its Inheritance Hierarchy see MDSN

Thanks to ShawnFeatherly for his answer

Say the remote is origin and the branch is master, and say you already have master checked out, might try the following:

git fetch origin
git reset --hard origin/master

This basically just takes the current branch and points it to the HEAD of the remote branch.

WARNING: As stated in the comments, this will throw away your local changes and overwrite with whatever is on the origin.

Or you can use the plumbing commands to do essentially the same:

git fetch <remote>
git update-ref refs/heads/<branch> $(git rev-parse <remote>/<branch>)
git reset --hard

EDIT: I'd like to briefly explain why this works.

The .git folder can hold the commits for any number of repositories. Since the commit hash is actually a verification method for the contents of the commit, and not just a randomly generated value, it is used to match commit sets between repositories.

A branch is just a named pointer to a given hash. Here's an example set:

$ find .git/refs -type f
.git/refs/tags/v3.8
.git/refs/heads/master
.git/refs/remotes/origin/HEAD
.git/refs/remotes/origin/master

Each of these files contains a hash pointing to a commit:

$ cat .git/refs/remotes/origin/master
d895cb1af15c04c522a25c79cc429076987c089b

These are all for the internal git storage mechanism, and work independently of the working directory. By doing the following:

git reset --hard origin/master

git will point the current branch at the same hash value that origin/master points to. Then it forcefully changes the working directory to match the file structure/contents at that hash.

To see this at work go ahead and try out the following:

git checkout -b test-branch
# see current commit and diff by the following
git show HEAD
# now point to another location
git reset --hard <remote>/<branch>
# see the changes again
git show HEAD

You can get the path via fp.name. Example:

>>> f = open('foo/bar.txt')
>>> f.name
'foo/bar.txt'

You might need os.path.basename if you want only the file name:

>>> import os
>>> f = open('foo/bar.txt')
>>> os.path.basename(f.name)
'bar.txt'

In [6]: data - vector[:,None]
Out[6]:
array([[0, 0, 0],
       [0, 0, 0],
       [0, 0, 0]])

In [7]: data / vector[:,None]
Out[7]:
array([[1, 1, 1],
       [1, 1, 1],
       [1, 1, 1]])

Sort Array In Swift

For Swifty Person below is a very clean technique to achieve above goal for globally. Lets have an example custom class of User which have some attributes.

class User: NSObject {
    var id: String?
    var name: String?
    var email: String?
    var createdDate: Date?
}

Now we have an array which we need to sort on the basis of createdDate either ascending and/or descending. So lets add a function for date comparison.

class User: NSObject {
    var id: String?
    var name: String?
    var email: String?
    var createdDate: Date?
    func checkForOrder(_ otherUser: User, _ order: ComparisonResult) -> Bool {
        if let myCreatedDate = self.createdDate, let othersCreatedDate = otherUser.createdDate {
            //This line will compare both date with the order that has been passed.
            return myCreatedDate.compare(othersCreatedDate) == order
        }
        return false
    }
}

Now lets have an extension of Array for User. In simple words lets add some methods only for those Array's which only have User objects in it.

extension Array where Element: User {
    //This method only takes an order type. i.e ComparisonResult.orderedAscending
    func sortUserByDate(_ order: ComparisonResult) -> [User] {
        let sortedArray = self.sorted { (user1, user2) -> Bool in
            return user1.checkForOrder(user2, order)
        }
        return sortedArray
    }
}

Usage for Ascending Order

let sortedArray = someArray.sortUserByDate(.orderedAscending)

Usage for Descending Order

let sortedArray = someArray.sortUserByDate(.orderedAscending)

Usage for Same Order

let sortedArray = someArray.sortUserByDate(.orderedSame)

Above method in extension will only be accessible if the Array is of type [User] || Array<User>

For me was php version from mac instead of MAMP, PATH variable on .bash_profile was wrong. I just prepend the MAMP PHP bin folder to the $PATH env variable. For me was:

/Applications/mampstack-7.1.21-0/php/bin

1. In terminal run vim ~/.bash_profile to open ~/.bash_profile

2. Type i to be able to edit the file, add the bin directory as PATH variable on the top to the file:

   export PATH="/Applications/mampstack-7.1.21-0/php/bin/:$PATH"

3. Hit ESC, Type :wq, and hit Enter

4. In Terminal run source ~/.bash_profile
5. In Terminal type which php, output should be the path to MAMP PHP install.

If you're using latest spring boot (with jdbc starter and Hikari) you'll run into: java.lang.IllegalArgumentException: jdbcUrl is required with driverClassName. To solve this:

1. In your application.properties:

datasource.oracle.url=youroracleurl

2. In your application define as bean (@Primary is mandatory!):

@Bean
@Primary
@ConfigurationProperties("datasource.oracle")
public DataSourceProperties getDatasourceProperties() {
    return new DataSourceProperties();
}

@Bean
@ConfigurationProperties("datasource.oracle")
public DataSource getDatasource() {
    return getDatasourceProperties().initializeDataSourceBuilder()
           .username("username")
           .password("password")
           .build();
}

json-schema-generator is a neat Ruby based JSON schema generator. It supports both draft 3 and 4 of the JSON schema. It can be run as a standalone executable, or it can be embedded inside of a Ruby script.

Then you can use json-schema to validate JSON samples against your newly generated schema if you want.

I use Portable winpython in Windows, it includes IPython QT console, I could achieve the following.

>>>print ("??")
??

>>>print ("????")
????

>>>str = "??"


>>>print (str)
??

your console interpreter should support unicode in order to show unicode characters.

Update for Python 3.9

In python 3.9 you could remove suffix using str.removesuffix('suffix')

From the docs,

If the string ends with the suffix string and that suffix is not empty, return string[:-len(suffix)]. Otherwise, return a copy of the original string:

set1  = {'Apple.good','Orange.good','Pear.bad','Pear.good','Banana.bad','Potato.bad'}

set2 = set()

for s in set1:
   set2.add(s.removesuffix(".good").removesuffix(".bad"))

or using set comprehension:

set2 = {s.removesuffix(".good").removesuffix(".bad") for s in set1}
   
print(set2)


Output:
{'Orange', 'Pear', 'Apple', 'Banana', 'Potato'}

Thanks to this answer for pointing it out!

I didn't see a good and complete answer to your question, so I will show a more complete example. There are some methods posted showing how to get integer input from the user, but whenever you do this you usually also need to

1. validate the input
2. display an error message if invalid input is given, and
3. loop through until a valid input is given.

This example shows how to get an integer value from the user that is equal to or greater than 1. If invalid input is given, it will catch the error, display an error message, and request the user to try again for a correct input.

static void Main(string[] args)
    {
        int intUserInput = 0;
        bool validUserInput = false;

        while (validUserInput == false)
        {
            try
            { Console.Write("Please enter an integer value greater than or equal to 1: ");
              intUserInput = int.Parse(Console.ReadLine()); //try to parse the user input to an int variable
            }  
            catch (Exception) { } //catch exception for invalid input.

            if (intUserInput >= 1) //check to see that the user entered int >= 1
              { validUserInput = true; }
            else { Console.WriteLine("Invalid input. "); }

        }//end while

        Console.WriteLine("You entered " + intUserInput);
        Console.WriteLine("Press any key to exit ");
        Console.ReadKey();
    }//end main

In your question it looks like you wanted to use this for menu options. So if you wanted to get int input for choosing a menu option you could change the if statement to

if ( (intUserInput >= 1) && (intUserInput <= 4) )

This would work if you needed the user to pick an option of 1, 2, 3, or 4.

I ended up using:

Function DirectoryExists(Directory As String) As Boolean
    DirectoryExists = False
    If Len(Dir(Directory, vbDirectory)) > 0 Then
        If (GetAttr(Directory) And vbDirectory) = vbDirectory Then
            DirectoryExists = True
        End If
    End If
End Function

            Context context = ((ContextWrapper) dialog.getContext()).getBaseContext();

            // if the Context used here was an activity AND it hasn't been finished or destroyed
            // then dismiss it

                // Api >=17
                if (!((Activity) context).isFinishing() {
                    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
                        if (!((Activity) context).isDestroyed()) {
                            dismissWithExceptionHandling(dialog);
                        }
                    } else { 
                        // Api < 17. Unfortunately cannot check for isDestroyed()
                        dismissWithExceptionHandling(dialog);
                    }
                }
            } else
                // if the Context used wasn't an Activity, then dismiss it too
                dismissWithExceptionHandling(dialog);
        }
        dialog = null;
    }
}

/**

public void dismissWithExceptionHandling(ProgressDialog dialog) {
    try {
        dialog.dismiss();
    } catch (final IllegalArgumentException e) {

    } catch (final Exception e) {
        // Do nothing.
    } finally {

Sometimes, good exception handling works well if there wasn't a better solution for this issue.

In case if you need the time to be zeros like 2018-01-17 00:00:00.000:

SELECT CONVERT(DATETIME, CONVERT(DATE, GETDATE()), 121)

import { readFileSync } from 'fs';

const file = readFileSync('./filename.txt', 'utf-8');

This worked for me. You may need to wrap the second command in any function or you may need to declare inside a class without keyword const.

If you don't have avahi installed then it's probably cups.

"/tmp/test.jpg" is not the correct path – this path starts with / which is the root directory.

In unix, the shortcut to the current directory is .

Try this "./tmp/test.jpg"

I've done this with a T4 template. It is fairly trivial to drop a .tt file into your project, and set up Visual Studio to run the T4 template as a pre-build step.

The T4 generates a .cs file, which means you can have it just query the database and build an enum in a .cs file from the result. Wired up as a pre-build task, it would re-create your enum on every build, or you can run the T4 manually as needed instead.

I use matplotlib for reading TIFF files:

import matplotlib.pyplot as plt
I = plt.imread(tiff_file)

and I will be of type ndarray.

According to the documentation though it is actually PIL that works behind the scenes when handling TIFFs as matplotlib only reads PNGs natively, but this has been working fine for me.

There's also a plt.imsave function for saving.

I know it's an old post but I had the same issue today, what I did is simple : changing my script that send my playbook from my local host to the server, before sending it with maven command, I did this :

cat common_vars.yml > vars.yml
cat snapshot_vars.yml >> vars.yml
# or 
#cat release_vars.yml >> vars.yml
mvn ....

There is also a simple answer for defining specific styles that are only going to be applied to that specific button and you can have Jquery declare element style when declaring the dialog:

id: "button-delete",
text: "Delete",
style: "display: none;",
click: function () {}

after doing that here is what the html shows:

doing this allows you to set it, but it is not necessarily easy to change using jquery later.

You should put the script as argument for a *NIX shell you run, equivalent to the *NIXish

sh myscriptfile

MyLocation is a Swift iOS Demo.

You can use this demo for the following:

1. Show the current location.

2. Choose other location: in this case stop tracking the location.

3. Add a push pin to a MKMapView(iOS) when touching.

You are writing to memory you do not own:

int board[2][50]; //make an array with 3 columns  (wrong)
                  //(actually makes an array with only two 'columns')
...
for (i=0; i<num3+1; i++)
    board[2][i] = 'O';
          ^

Change this line:

int board[2][50]; //array with 2 columns (legal indices [0-1][0-49])
          ^

To:

int board[3][50]; //array with 3 columns (legal indices [0-2][0-49])
          ^

When creating an array, the value used to initialize: [3] indicates array size.
However, when accessing existing array elements, index values are zero based.

For an array created: int board[3][50];
Legal indices are board[0][0]...board[2][49]

EDIT To address bad output comment and initialization comment

add an additional "\n" for formatting output:

Change:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
 }

       ...

To:

  ...
  for (k=0; k<50;k++) {
     printf("%d",board[j][k]);
  }
  printf("\n");//at the end of every row, print a new line
}
...  

Initialize board variable:

int board[3][50] = {0};//initialize all elements to zero

( array initialization discussion... )

if you have directory on your path where you want to sign with a given identifyfile you can specify to use a specific identify file via the .ssh/config file by setting the ControlPath e.g.:

host github.com
  ControlPath ~/Projects/work/**
  HostName github.com
  IdentityFile ~/.ssh/id_work
  User git

Then ssh will use the specified identity file when doing git commands under the given work path.

Unix and Windows both have things called "Named pipes", but they behave differently. On Unix, a named pipe is a one-way street which typically has just one reader and one writer - the writer writes, and the reader reads, you get it?

On Windows, the thing called a "Named pipe" is an IPC object more like a TCP socket - things can flow both ways and there is some metadata (You can obtain the credentials of the thing on the other end etc).

Unix named pipes appear as a special file in the filesystem and can be accessed with normal file IO commands including the shell. Windows ones don't, and need to be opened with a special system call (after which they behave mostly like a normal win32 handle).

Even more confusing, Unix has something called a "Unix socket" or AF_UNIX socket, which works more like (but not completely like) a win32 "named pipe", being bidirectional.

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

To add to the response from @Anish, if you are having issues with not seeing the text when exporting the SVG to an image, you can create a recursive function to loop through the children of the SVGDocument, try to cast it to a SvgText if possible (add your own error checking) and set the font family and style.

    foreach(var child in svgDocument.Children)
    {
        SetFont(child);
    }

    public void SetFont(SvgElement element)
    {
        foreach(var child in element.Children)
        {
            SetFont(child); //Call this function again with the child, this will loop
                            //until the element has no more children
        }

        try
        {
            var svgText = (SvgText)parent; //try to cast the element as a SvgText
                                           //if it succeeds you can modify the font

            svgText.Font = new Font("Arial", 12.0f);
            svgText.FontSize = new SvgUnit(12.0f);
        }
        catch
        {

        }
    }

Let me know if there are questions.

Date has the time part, so we only need to extract it from Date

I personally prefer the default format parameter of the Date when date and time needs to be separated instead of using the extra SimpleDateFormat

Date date = new Date()
String datePart = date.format("dd/MM/yyyy")
String timePart = date.format("HH:mm:ss")

println "datePart : " + datePart + "\ttimePart : " + timePart

Consider this:

abstract class Product { 
    int value;
    public Product( int val ) {
        value= val;
    }
    abstract public int multiply();
}

class TimesTwo extends Product {
    public int mutiply() {
       return value * 2;
    }
}

The superclass is abstract and has a constructor.

It also depends on what you need. For basic SQL transactions you could try doing TSQL transactions by using BEGIN TRANS and COMMIT TRANS in your code. That is the easiest way but it does have complexity and you have to be careful to commit properly (and rollback).

I would use something like

SQLTransaction trans = null;
using(trans = new SqlTransaction)
{
    ...
    Do SQL stuff here passing my trans into my various SQL executers
    ...
    trans.Commit  // May not be quite right
}

Any failure will pop you right out of the using and the transaction will always commit or rollback (depending on what you tell it to do). The biggest problem we faced was making sure it always committed. The using ensures the scope of the transaction is limited.

mvn install (or mvn package) will always work.

You can use mvn compile to download compile time dependencies or mvn test for compile time and test dependencies but I prefer something that always works.

This isn't an answer to the tagline question, but it is an answer to the problems mentioned in the body of the question. Instead of using @Before or @After, look into using @org.junit.Rule because it gives you more flexibility. ExternalResource (as of 4.7) is the rule you will be most interested in if you are managing connections. Also, If you want guaranteed execution order of your rules use a RuleChain (as of 4.10). I believe all of these were available when this question was asked. Code example below is copied from ExternalResource's javadocs.

 public static class UsesExternalResource {
  Server myServer= new Server();

  @Rule
  public ExternalResource resource= new ExternalResource() {
      @Override
      protected void before() throws Throwable {
          myServer.connect();
         };

      @Override
      protected void after() {
          myServer.disconnect();
         };
     };

  @Test
  public void testFoo() {
      new Client().run(myServer);
     }
 }

You can create your own shortcut for increase/Decrease Netbeans Fonts size

just goto Tools > Options > Keymaps than search zoom

click on three (...) dot and click Edit

You should amend creation of the gesture recogniser to accept parameter (add colon ':')

UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)];

And in your method highlightLetter: you can access the view attached to recogniser:

-(IBAction) highlightLetter:(UITapGestureRecognizer*)recognizer
{
    UIView *view = [recognizer view];
}

Building on alko's answer that almost worked for me, except for the filtering step (where I get: ValueError: cannot reindex from a duplicate axis), here is the final solution I used:

# join the dataframes
united_data = pd.concat([data1, data2, data3, ...])
# group the data by the whole row to find duplicates
united_data_grouped = united_data.groupby(list(united_data.columns))
# detect the row indices of unique rows
uniq_data_idx = [x[0] for x in united_data_grouped.indices.values() if len(x) == 1]
# extract those unique values
uniq_data = united_data.iloc[uniq_data_idx]

If your XML goes quite deep, you might want to consider using XPath, which comes with your JRE, so you can access the contents far more easily using:

String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()", 
    document.getDocumentElement());

Full example:

import static org.junit.Assert.assertEquals;
import java.io.StringReader;    
import javax.xml.parsers.DocumentBuilder;
import javax.xml.parsers.DocumentBuilderFactory;
import javax.xml.xpath.XPath;
import javax.xml.xpath.XPathFactory;    
import org.junit.Before;
import org.junit.Test;
import org.w3c.dom.Document;
import org.xml.sax.InputSource;

public class XPathTest {

    private Document document;

    @Before
    public void setup() throws Exception {
        String xml = "<add job=\"351\"><tag>foobar</tag><tag>foobar2</tag></add>";
        DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
        DocumentBuilder db = dbf.newDocumentBuilder();
        document = db.parse(new InputSource(new StringReader(xml)));
    }

    @Test
    public void testXPath() throws Exception {
        XPathFactory xpf = XPathFactory.newInstance();
        XPath xp = xpf.newXPath();
        String text = xp.evaluate("//add[@job='351']/tag[position()=1]/text()",
                document.getDocumentElement());
        assertEquals("foobar", text);
    }
}

As the comment stated, this is in C# not Java but the idea is the same. I've researched this issue extensively and ultimately the issue is, FindElement always returns an exception when the element doesn't exist. There isn't an overloaded option that allows you to get null or anything else. Here is why I prefer this solution over others.

1. Returning a list of elements then checking if the list size is 0 works but you lose functionality that way. You can't do a .click() on a collection of links even if the collection size is 1.
2. You could assert that the element exists but often that stops your testing. In some cases, I have an extra link to click depending on how I got to that page and I want to click it if it exists or move on otherwise.
3. It's only slow if you don't set the timeout driver.Manage().Timeouts().ImplicitlyWait(TimeSpan.FromSeconds(0));

4. It's actually a very simple and elegant once the method is created. By using FindElementSafe instead of FindElement, I don't "see" the ugly try/catch block and I can use a simple Exists method. That would look something like this:

   IWebElement myLink = driver.FindElementSafe(By.Id("myId"));
   if (myLink.Exists)
   {
      myLink.Click();
   }
   

Here is how you extend IWebElement & IWebDriver

IWebDriver.FindElementSafe

    /// <summary>
    /// Same as FindElement only returns null when not found instead of an exception.
    /// </summary>
    /// <param name="driver">current browser instance</param>
    /// <param name="by">The search string for finding element</param>
    /// <returns>Returns element or null if not found</returns>
    public static IWebElement FindElementSafe(this IWebDriver driver, By by)
    {
        try
        {
            return driver.FindElement(by);
        }
        catch (NoSuchElementException)
        {
            return null;
        }
    }

IWebElement.Exists

    /// <summary>
    /// Requires finding element by FindElementSafe(By).
    /// Returns T/F depending on if element is defined or null.
    /// </summary>
    /// <param name="element">Current element</param>
    /// <returns>Returns T/F depending on if element is defined or null.</returns>
    public static bool Exists(this IWebElement element)
    {
        if (element == null)
        { return false; }
        return true;
    }

You could use polymorphism to modify the IWebDriver class instance of FindElement but that's a bad idea from a maintenance standpoint.

Try this piece of code, it worked for me:

$('#year').datepicker({
    format: "yyyy",
    viewMode: "years",
    minViewMode: "years"
});

I hope it will do magic also for you.

Amazingly now org.json now lets you put a byte[] object directly into a json and it remains readable. you can even send the resulting object over a websocket and it will be readable on the other side. but i am not sure yet if the size of the resulting object is bigger or smaller than if you were converting your byte array to base64, it would certainly be neat if it was smaller.

It seems to be incredibly hard to measure how much space such a json object takes up in java. if your json consists merely of strings it is easily achievable by simply stringifying it but with a bytearray inside it i fear it is not as straightforward.

stringifying our json in java replaces my bytearray for a 10 character string that looks like an id. doing the same in node.js replaces our byte[] for an unquoted value reading <Buffered Array: f0 ff ff ...> the length of the latter indicates a size increase of ~300% as would be expected

If you are in Chrome you can check the Post Data

Here is How to check the Post data

1. Go to Network Tab
2. Look for the Link to which you are sending Post Data
3. Click on it
4. In the Headers, you can check Request Payload to check the post data

As a workaround to force the evaluation of the SELECT clause before the WHERE clause, you could put the former in a sub-query while the latter remains in the main query:

SELECT * FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices) AS temp
WHERE BalanceDue > 0
  

center-block is bad idea as it covers a portion on your screen and you cannot click on your fields or buttons. col-md-offset-? is better option.

Use col-md-offset-3 is better option if class is col-sm-6. Just change the number to center your block.

A visual answer

Imagine a <span> element inside a <div>. If you give the <span> element a height of 100px and a red border for example, it will look like this with

display: inline

display: inline-block

display: block

Code: http://jsfiddle.net/Mta2b/

Elements with display:inline-block are like display:inline elements, but they can have a width and a height. That means that you can use an inline-block element as a block while flowing it within text or other elements.

Difference of supported styles as summary:

• inline: only margin-left, margin-right, padding-left, padding-right
• inline-block: margin, padding, height, width

You can use like this.

when: condition1 == "condition1" or condition2 == "condition2"

first ensure that your table storage engine type should be innoDB (you can set it using Table operations Tab)

if you are using new phpmyadmin then use new "Relation view" tab to make foreign key relation

if you are using old version of phpmyadmin then the "relation view" button will show on the bottom of the table columns

You can get an array of the individual characters like so

var test = "test string",
    characters = test.split('');

and then loop using regular Javascript, or else you can iterate over the string's characters using jQuery by

var test = "test string";

$(test.split('')).each(function (index,character) {
    alert(character);
});

Use FirstOrDefault insted of SingleOrDefault..

SingleOrDefault returns a SINGLE element or null if no element is found. If 2 elements are found in your Enumerable then it throws the exception you are seeing

FirstOrDefault returns the FIRST element it finds or null if no element is found. so if there are 2 elements that match your predicate the second one is ignored

   public int GetPackage(int id,int emp)
           {
             int getpackages=Convert.ToInt32(EmployerSubscriptionPackage.GetAllData().Where(x
   => x.SubscriptionPackageID ==`enter code here` id && x.EmployerID==emp ).FirstOrDefault().ID);
               return getpackages;
           }

 1. var EmployerId = Convert.ToInt32(Session["EmployerId"]);
               var getpackage = GetPackage(employerSubscription.ID, EmployerId);

// a wrapper closure around executing a string

// prints all output, complains and halts on error                              
def runCommand = { strList ->
  assert ( strList instanceof String ||
           ( strList instanceof List && strList.each{ it instanceof String } ) \
)
  def proc = strList.execute()
  proc.in.eachLine { line -> println line }
  proc.out.close()
  proc.waitFor()

  print "[INFO] ( "
  if(strList instanceof List) {
    strList.each { print "${it} " }
  } else {

  if (proc.exitValue()) {
    println "gave the following error: "

}

You can do Invalidate Caches / Restart for your case.

What you've got (according to the debug image) is an object array containing a string array. So you need something like:

Object[] objects = (Object[]) values;
String[] strings = (String[]) objects[0];

You haven't shown the type of values - if this is already Object[] then you could just use (String[])values[0].

Of course even with the cast to Object[] you could still do it in one statement, but it's ugly:

String[] strings = (String[]) ((Object[])values)[0];

This should work:

p <- ggplot(df, aes(x=rating, fill=cond)) + 
           geom_density(alpha=.3) + 
           xlab("NEW RATING TITLE") + 
           ylab("NEW DENSITY TITLE")
p <- p + guides(fill=guide_legend(title="New Legend Title"))

(or alternatively)

p + scale_fill_discrete(name = "New Legend Title")

EDIT 2017-04-29: As pointed to by some of the commenters, the JoinTable example does not need the mappedBy annotation attribute. In fact, recent versions of Hibernate refuse to start up by printing the following error:

org.hibernate.AnnotationException: 
   Associations marked as mappedBy must not define database mappings 
   like @JoinTable or @JoinColumn

Let's pretend that you have an entity named Project and another entity named Task and each project can have many tasks.

You can design the database schema for this scenario in two ways.

The first solution is to create a table named Project and another table named Task and add a foreign key column to the task table named project_id:

Project      Task
-------      ----
id           id
name         name
             project_id

This way, it will be possible to determine the project for each row in the task table. If you use this approach, in your entity classes you won't need a join table:

@Entity
public class Project {

   @OneToMany(mappedBy = "project")
   private Collection<Task> tasks;

}

@Entity
public class Task {

   @ManyToOne
   private Project project;

}

The other solution is to use a third table, e.g. Project_Tasks, and store the relationship between projects and tasks in that table:

Project      Task      Project_Tasks
-------      ----      -------------
id           id        project_id
name         name      task_id

The Project_Tasks table is called a "Join Table". To implement this second solution in JPA you need to use the @JoinTable annotation. For example, in order to implement a uni-directional one-to-many association, we can define our entities as such:

Project entity:

@Entity
public class Project {

    @Id
    @GeneratedValue
    private Long pid;

    private String name;

    @JoinTable
    @OneToMany
    private List<Task> tasks;

    public Long getPid() {
        return pid;
    }

    public void setPid(Long pid) {
        this.pid = pid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public List<Task> getTasks() {
        return tasks;
    }

    public void setTasks(List<Task> tasks) {
        this.tasks = tasks;
    }
}

Task entity:

@Entity
public class Task {

    @Id
    @GeneratedValue
    private Long tid;

    private String name;

    public Long getTid() {
        return tid;
    }

    public void setTid(Long tid) {
        this.tid = tid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

}

This will create the following database structure:

The @JoinTable annotation also lets you customize various aspects of the join table. For example, had we annotated the tasks property like this:

@JoinTable(
        name = "MY_JT",
        joinColumns = @JoinColumn(
                name = "PROJ_ID",
                referencedColumnName = "PID"
        ),
        inverseJoinColumns = @JoinColumn(
                name = "TASK_ID",
                referencedColumnName = "TID"
        )
)
@OneToMany
private List<Task> tasks;

The resulting database would have become:

Finally, if you want to create a schema for a many-to-many association, using a join table is the only available solution.

Assuming staff_id + date form a uk, this is another method:

SELECT STAFF_ID, SITE_ID, PAY_LEVEL
  FROM TABLE t
  WHERE END_ENROLLMENT_DATE is null
    AND DATE = (SELECT MAX(DATE)
                  FROM TABLE
                  WHERE staff_id = t.staff_id
                    AND DATE <= SYSDATE)

If you have a lot of files in the directory then glob2 might be a better option to generate a list of filenames rather than writing them by hand.

import glob2

filenames = glob2.glob('*.txt')  # list of all .txt files in the directory

with open('outfile.txt', 'w') as f:
    for file in filenames:
        with open(file) as infile:
            f.write(infile.read()+'\n')

In my case neither Windows Features nor aspnet_regiis -i didn't do the work. After hours of digging in the Internet, I made my own solution:

1. In the IIS Manager in Modules I changed inherit to local in UrlRoutingModule-4.0 node:

   

2. In web.config I pasted a mix of some tips from this forum:

   <system.webServer>
       <modules runAllManagedModulesForAllRequests="true">
           <remove name="UrlRoutingModule-4.0"></remove>
           <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition=""></add>
       </modules>
   </system.webServer>
   

Hope it helps

Matplotlib uses a dictionary from its colors.py module.

To print the names use:

# python2:

import matplotlib
for name, hex in matplotlib.colors.cnames.iteritems():
    print(name, hex)

# python3:

import matplotlib
for name, hex in matplotlib.colors.cnames.items():
    print(name, hex)

This is the complete dictionary:

You could plot them like this:

import matplotlib.pyplot as plt
import matplotlib.patches as patches
import matplotlib.colors as colors
import math


fig = plt.figure()
ax = fig.add_subplot(111)

ratio = 1.0 / 3.0
count = math.ceil(math.sqrt(len(colors.cnames)))
x_count = count * ratio
y_count = count / ratio
x = 0
y = 0
w = 1 / x_count
h = 1 / y_count

for c in colors.cnames:
    pos = (x / x_count, y / y_count)
    ax.add_patch(patches.Rectangle(pos, w, h, color=c))
    ax.annotate(c, xy=pos)
    if y >= y_count-1:
        x += 1
        y = 0
    else:
        y += 1

plt.show()

In Swift 3.0

images.sort(by: { (first: imageFile, second: imageFile) -> Bool in
    first. fileID < second. fileID
})

This worked for me. In your project go to: storage > framework > views. Delete all the files in there and refresh your page.

The main difference is that sorted(some_list) returns a new list:

a = [3, 2, 1]
print sorted(a) # new list
print a         # is not modified

and some_list.sort(), sorts the list in place:

a = [3, 2, 1]
print a.sort() # in place
print a         # it's modified

Note that since a.sort() doesn't return anything, print a.sort() will print None.

Can a list original positions be retrieved after list.sort()?

No, because it modifies the original list.

Try:

CREATE TABLE test (
  ID INTEGER,
  NAME VARCHAR (50),
  VALUE INTEGER
);

INSERT INTO test VALUES (1, 'A', 4);
INSERT INTO test VALUES (1, 'A', 5);
INSERT INTO test VALUES (1, 'B', 8);
INSERT INTO test VALUES (2, 'C', 9);

SELECT ID, GROUP_CONCAT(NAME ORDER BY NAME ASC SEPARATOR ',')
FROM (
  SELECT ID, CONCAT(NAME, ':', GROUP_CONCAT(VALUE ORDER BY VALUE ASC SEPARATOR ',')) AS NAME
  FROM test
  GROUP BY ID, NAME
) AS A
GROUP BY ID;

You have two options here, you can make it open in a new window/tab with JS:

<td onClick={()=> window.open("someLink", "_blank")}>text</td>

But a better option is to use a regular link but style it as a table cell:

<a style={{display: "table-cell"}} href="someLink" target="_blank">text</a>

For me, it is because of access denied to C:\ProgramData\Docker\config\daemon.json After I fixed it now it works. You can try to switch to Linux containers and switch back. If there is no problem with the switching, then it works with the access permission.

You can achieve it:

 $(document).ready(function(){              
     $('#textBox').keyup(function () {alert('changed');});
 });

or with change (handle copy paste with right click):

 $(document).ready(function(){              
     $('#textBox2').change(function () {alert('changed');});
 });

Here is Demo

I found an easy resolution for this issue was to add source /etc/profile to the top of the script.sh file I was trying to run on the target system. On the systems here, this caused the environmental variables which were needed by script.sh to be configured as if running from a login shell.

In one of the prior responses it was suggested that ~/.bashr_profile etc... be used. I didn't spend much time on this but, the problem with this is if you ssh to a different user on the target system than the shell on the source system from which you log in it appeared to me that this causes the source system user name to be used for the ~.

Use StringUtils, in case you need string result:

String last = StringUtils.right(number.toString(), 1);

-eq is used to compare integers. Use = instead.

1. create table xyz_new as select * from xyz;

-- This will create table and copy all data.

2. delete from xyz_new;

-- This will have same table structure but all data copied will be deleted.

If you want to overcome the limitations specified by answer: How can I create a copy of an Oracle table without copying the data?

You can use WScript.ScriptFullName which will return the full path of the executing script.

You can then use string manipulation (jscript example) :

scriptdir = WScript.ScriptFullName.substring(0,WScript.ScriptFullName.lastIndexOf(WScript.ScriptName)-1)

Or get help from FileSystemObject, (vbscript example) :

scriptdir = CreateObject("Scripting.FileSystemObject").GetParentFolderName(WScript.ScriptFullName)

A good plugin that I have used before is DataTables.

My Table didn't have primary key then I had time out error. after set key sloved.

Wrap your reader in a BufferedReader, which maintains a buffer allowing for much faster reads overall. You can then use read() to read a single character (which you'll need to cast). You can also use readLine() to fetch an entire line and then break that into individual characters. The BufferedReader also supports marking and returning, so if you need to, you can read a line multiple times.

Generally speaking, you want to use a BufferedReader or BufferedInputStream on top of whatever stream you are actually using since the buffer they maintain will make multiple reads much faster.

From Wikipedia,

A database management system (DBMS) is a computer software application that interacts with the user, other applications, and the database itself to capture and analyze data. A general-purpose DBMS is designed to allow the definition, creation, querying, update, and administration of databases.

There are different types of DBMS products: relational, network and hierarchical. The most widely commonly used type of DBMS today is the Relational Database Management Systems (RDBMS)

DBMS:

• A DBMS is a storage area that persist the data in files.
• There are limitations to store records in a single database file.
• DBMS allows the relations to be established between 2 files.
• Data is stored in flat files with metadata.
• DBMS does not support client / server architecture.
• DBMS does not follow normalization. Only single user can access the data.
• DBMS does not impose integrity constraints.
• ACID properties of database must be implemented by the user or the developer

RDBMS:

• RDBMS stores the data in tabular form.
• It has additional condition for supporting tabular structure or data that enforces relationships among tables.
• RDBMS supports client/server architecture.
• RDBMS follows normalization.
• RDBMS allows simultaneous access of users to data tables.
• RDBMS imposes integrity constraints.
• ACID properties of the database are defined in the integrity constraints.
