A related issue: I came to this page after searching for "how to know what are deleted branches".
While deleting many old branches, felt I mistakenly deleted one of the newer branches, but didn't know the name to recover it.
To know what branches are deleted recently, do the below:
If you go to your Git URL, which will look something like this:
https://your-website-name/orgs/your-org-name/dashboard
Then you can see the feed, of what is deleted, by whom, in the recent past.
Root node is the DocumentElement
property of XmlDocument
XmlElement root = xmlDoc.DocumentElement
If you only have the node, you can get the root node by
XmlElement root = xmlNode.OwnerDocument.DocumentElement
Compiler knows by type cast. Given a void *x
:
x+1
adds one byte to x
, pointer goes to byte x+1
(int*)x+1
adds sizeof(int)
bytes, pointer goes to byte x + sizeof(int)
(float*)x+1
addres sizeof(float)
bytes,
etc.Althought the first item is not portable and is against the Galateo of C/C++, it is nevertheless C-language-correct, meaning it will compile to something on most compilers possibly necessitating an appropriate flag (like -Wpointer-arith)
In python notebooks I often want to filter out 'dangling' numpy.ndarray
's, in particular the ones that are stored in _1
, _2
, etc that were never really meant to stay alive.
I use this code to get a listing of all of them and their size.
Not sure if locals()
or globals()
is better here.
import sys
import numpy
from humanize import naturalsize
for size, name in sorted(
(value.nbytes, name)
for name, value in locals().items()
if isinstance(value, numpy.ndarray)):
print("{:>30}: {:>8}".format(name, naturalsize(size)))
Processing speed may not be the only relevant matter, however, as that's the question, here are some numbers in a benchmark: JSON vs. XML: Some hard numbers about verbosity. For the speed, in this simple benchmark, XML presents a 21% overhead over JSON.
An important note about the verbosity, which is as the article says, the most common complain: this is not so much relevant in practice (neither XML nor JSON data are typically handled by humans, but by machines), even if for the matter of speed, it requires some reasonable more time to compress.
Also, in this benchmark, a big amount of data was processed, and a typical web application won't transmit data chunks of such sizes, as big as 90MB, and compression may not be beneficial (for small enough data chunks, a compressed chunk will be bigger than the uncompressed chunk), so not applicable.
Still, if no compression is involved, JSON, as obviously terser, will weight less over the transmission channel, especially if transmitted through a WebSocket connection, where the absence of the classic HTTP overhead may make the difference at the advantage of JSON, even more significant.
After transmission, data is to be consumed, and this count in the overall processing time. If big or complex enough data are to be transmitted, the lack of a schema automatically checked for by a validating XML parser, may require more check on JSON data; these checks would have to be executed in JavaScript, which is not known to be particularly fast, and so it may present an additional overhead over XML in such cases.
Anyway, only testing will provides the answer for your particular use-case (if speed is really the only matter, and not standard nor safety nor integrity…).
Update 1: worth to mention, is EXI, the binary XML format, which offers compression at less cost than using Gzip, and save processing otherwise needed to decompress compressed XML. EXI is to XML, what BSON is to JSON. Have a quick overview here, with some reference to efficiency in both space and time: EXI: The last binary standard?.
Update 2: there also exists a binary XML performance reports, conducted by the W3C, as efficiency and low memory and CPU footprint, is also a matter for the XML area too: Efficient XML Interchange Evaluation.
Worth to be noticed in this context, as HTTP overhead was raised as an issue: the IANA has registered the EXI encoding (the efficient binary XML mentioned above), as a a Content Coding for the HTTP protocol (alongside with compress, deflate and gzip). This means EXI is an option which can be expected to be understood by browsers among possibly other HTTP clients. See Hypertext Transfer Protocol Parameters (iana.org).
I have used a tool in my work its LDRA tool suite
It is used for testing the c/c++ code but it also can check against coding standards such as MISRA etc.
#include <iostream.h>
#include<typeinfo.h>

If your data field is already a DateTime datatype, you don't need to use [DataType(DataType.Date)]
for the annotation; just use:
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:MM/dd/yyyy}")]
on the jQuery, use datepicker for you calendar
$(document).ready(function () {
$('#StartDate').datepicker();
});
on your HTML, use EditorFor
helper:
@Html.EditorFor(model => model.StartDate)
You could do this using my Common Node library:
function get(url) {
return new (require('httpclient').HttpClient)({
method: 'GET',
url: url
}).finish().body.read().decodeToString();
}
var a = get('www.example.com/api_1.php'),
b = get('www.example.com/api_2.php'),
c = get('www.example.com/api_3.php');
For Windows Service, you need to run tomcat9w.exe (or 6w/7w/8w) depending on your version of tomcat. First, make sure tomcat is stopped. Then double click on tomcat9w.exe. Navigate to the Java tab. If you know you have 64 bit Windows with 64 bit Java and 64 bit Tomcat, then feel free to set the memory higher than 512. You'll need to do some task manager monitoring to determine how high to set it. For most apps developed in 2019... I'd recommend an initial memory pool of 1024, and the maximum memory pool of 2048. Of course if your computer has tons of RAM... feel free to go as high as you want. Also, see this answer: How to increase Maximum Memory Pool Size? Apache Tomcat 9

Result is:

The container's IP address should be properly configured inside of its network namespace, so any of the standard linux tools can get it. For example, try ifconfig
, ip addr show
, hostname -I
, etc. from an attached shell within one of your containers to test it out.
You can pass the inline handler the this
keyword, obtaining the element which fired the event.
like,
onclick="confirmSubmit(this);"
You have to specify the folder where you are saving it and it has to exist, in other case it will throw an error.
var s = txt.CreateTextFile("c:\\11.txt", true);
Since PHP 7.1 we have proper destructuring for lists. Thereby you can do things like this:
$test = [1, 2, 3, 4];
[$a, $b, $c, $d] = $test;
echo($a);
> 1
echo($d);
> 4
In a function this would look like this:
function multiple_return() {
return ['this', 'is', 'a', 'test'];
}
[$first, $second, $third, $fourth] = multiple_return();
echo($first);
> this
echo($fourth);
> test
Destructuring is a very powerful tool. It's capable of destructuring key=>value pairs as well:
["a" => $a, "b" => $b, "c" => $c] = ["a" => 1, "b" => 2, "c" => 3];
Take a look at the new feature page for PHP 7.1:
Finally managed to solve all the issues, so I'll answer my own question. These are the settings/files I've used to manage to get my particular problem(s) solved;
The client's keystore is a PKCS#12 format file containing
To generate it I used OpenSSL's pkcs12
command, for example;
openssl pkcs12 -export -in client.crt -inkey client.key -out client.p12 -name "Whatever"
Tip: make sure you get the latest OpenSSL, not version 0.9.8h because that seems to suffer from a bug which doesn't allow you to properly generate PKCS#12 files.
This PKCS#12 file will be used by the Java client to present the client certificate to the server when the server has explicitly requested the client to authenticate. See the Wikipedia article on TLS for an overview of how the protocol for client certificate authentication actually works (also explains why we need the client's private key here).
The client's truststore is a straight forward JKS format file containing the root or intermediate CA certificates. These CA certificates will determine which endpoints you will be allowed to communicate with, in this case it will allow your client to connect to whichever server presents a certificate which was signed by one of the truststore's CA's.
To generate it you can use the standard Java keytool, for example;
keytool -genkey -dname "cn=CLIENT" -alias truststorekey -keyalg RSA -keystore ./client-truststore.jks -keypass whatever -storepass whatever
keytool -import -keystore ./client-truststore.jks -file myca.crt -alias myca
Using this truststore, your client will try to do a complete SSL handshake with all servers who present a certificate signed by the CA identified by myca.crt
.
The files above are strictly for the client only. When you want to set-up a server as well, the server needs its own key- and truststore files. A great walk-through for setting up a fully working example for both a Java client and server (using Tomcat) can be found on this website.

-Djavax.net.debug=ssl
but is more structured and (arguably) easier to interpret if you're uncomfortable with the Java SSL debug output.It's perfectly possible to use the Apache httpclient library. If you want to use httpclient, just replace the destination URL with the HTTPS equivalent and add the following JVM arguments (which are the same for any other client, regardless of the library you want to use to send/receive data over HTTP/HTTPS):
-Djavax.net.debug=ssl
-Djavax.net.ssl.keyStoreType=pkcs12
-Djavax.net.ssl.keyStore=client.p12
-Djavax.net.ssl.keyStorePassword=whatever
-Djavax.net.ssl.trustStoreType=jks
-Djavax.net.ssl.trustStore=client-truststore.jks
-Djavax.net.ssl.trustStorePassword=whatever
Platform.runLater works to prevent execution until initialization is complete. In this case, i want to refresh a list view every time I resize the window width.
Platform.runLater(() -> {
((Stage) listView.getScene().getWindow()).widthProperty().addListener((obs, oldVal, newVal) -> {
listView.refresh();
});
});
in your case
Platform.runLater(()->{
((Stage)myPane.getScene().getWindow()).setOn*whatIwant*(...);
});
This is the code I use for the task:
// `activity` is an instance of Activity class.
Display display = activity.getWindowManager().getDefaultDisplay();
Point screen = new Point();
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB_MR2) {
display.getSize(screen);
} else {
screen.x = display.getWidth();
screen.y = display.getHeight();
}
Seems clean enough and yet, takes care of the deprecation.
I think that there is a more simple approach to all given here, and is the method Number.toFixed()
already implemented in JavaScript.
simply write:
var myNumber = 2;
myNumber.toFixed(2); //returns "2.00"
myNumber.toFixed(1); //returns "2.0"
etc...
A silly bug that got me: the joins failed because index dtypes
differed. This was not obvious as both tables were pivot tables of the same original table. After reset_index
, the indices looked identical in Jupyter. It only came to light when saving to Excel...
Fixed with: df1[['key']] = df1[['key']].apply(pd.to_numeric)
Hopefully this saves somebody an hour!
I've cloned a super handy tool that adds a context menu entry for assemblies in the windows explorer to show all available info:
Download here: https://github.com/tebjan/AssemblyInformation/releases
pip3
not pip
. You can create an alias like you did with python3
if you like.
Simply Add 'carousel-item' class in place of item class.
Well you said without redirecting. Well its a javascript code:
<a href="JavaScript:void(0);" onclick="function()">Whatever!</a>
<script type="text/javascript">
function confirm_delete() {
var delete_confirmed=confirm("Are you sure you want to delete this file?");
if (delete_confirmed==true) {
// the php code :) can't expose mine ^_^
} else {
// this one returns the user if he/she clicks no :)
document.location.href = 'whatever.php';
}
}
</script>
give it a try :) hope you like it
If you are using Bootstrap CSS...
I have created a simple re-usable tree control (directive) for AngularJS based on a Bootstrap "nav" list. I added extra indentation, icons, and animation. HTML attributes are used for configuration.
It does not use recursion.
I called it angular-bootstrap-nav-tree ( catchy name, don't you think? )
To concat files in command prompt it would be
type file1.txt file2.txt file3.txt > files.txt
PowerShell converts the type
command to Get-Content
, which means you will get an error when using the type
command in PowerShell because the Get-Content
command requires a comma separating the files. The same command in PowerShell would be
Get-Content file1.txt,file2.txt,file3.txt | Set-Content files.txt
Are you looking for exit

I think what's missing here is that when you do:
>pip install .
to install a local package with a setup.py, it installs a package that is visible to all the conda envs that use the same version of python. Note I am using the conda version of pip!
e.g., if I'm using python2.7 it puts the local package here:
/usr/local/anaconda/lib/python2.7/site-packages
If I then later create a new conda env with python=2.7 (= the default):
>conda create --name new
>source activate new
And then do:
(new)>conda list // empty - conda is not aware of any packages yet
However, if I do:
(new)>pip list // the local package installed above is present
So in this case, conda does not know about the pip package, but the package is available to python.
However, If I instead install the local package (again using pip) after I've created (and activated) the new conda env, now conda sees it:
(new)>conda list // sees that the package is there and was installed by pip
So I think the interaction between conda and pip has some issues - ie, using pip to install a local package from within one conda env makes that package available (but not seen via conda list) to all other conda envs of the same python version.
If you like the idea of Views, but are worried about performance you can get Oracle to create a cached table representing the view which oracle keeps up to date.
See materialized views
For python 2.7 another trick is:
arr = [1,2,3]
for num in arr:
print num,
# will print 1 2 3
Another way is to use the subplots
function and pass the width ratio with gridspec_kw
:
import numpy as np
import matplotlib.pyplot as plt
# generate some data
x = np.arange(0, 10, 0.2)
y = np.sin(x)
# plot it
f, (a0, a1) = plt.subplots(1, 2, gridspec_kw={'width_ratios': [3, 1]})
a0.plot(x, y)
a1.plot(y, x)
f.tight_layout()
f.savefig('grid_figure.pdf')
Using Android studio 1.5.1 i got the following warnings:
Call requires API level 16 (current min is 9): android.view.View#setBackground
and the complaints about deprecation
'setBackgroundDrawable(android.graphics.drawable.Drawable)' is deprecated
Using this format, i got rid of both:
if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.JELLY_BEAN) {
//noinspection deprecation
layout.setBackgroundDrawable(drawable);
} else {
layout.setBackground(drawable);
}
Generally, a stored procedure is a "SQL Function." They have:
-- a name
CREATE PROCEDURE spGetPerson
-- parameters
CREATE PROCEDURE spGetPerson(@PersonID int)
-- a body
CREATE PROCEDURE spGetPerson(@PersonID int)
AS
SELECT FirstName, LastName ....
FROM People
WHERE PersonID = @PersonID
This is a T-SQL focused example. Stored procedures can execute most SQL statements, return scalar and table-based values, and are considered to be more secure because they prevent SQL injection attacks.
you can do it like this:
<script>
function SomeDeleteRowFunction(o) {
//no clue what to put here?
var p=o.parentNode.parentNode;
p.parentNode.removeChild(p);
}
</script>
<table>
<tr>
<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
</tr>
<tr>
<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
</tr>
<tr>
<td><input type="button" value="Delete Row" onclick="SomeDeleteRowFunction(this)"></td>
</tr>
</table>
generateNumbers()
expects a parameter and you aren't passing one in!
generateNumbers() also returns after it has set the first random number - seems to be some confusion about what it is trying to do.
You need to prevent the default event (following the link), otherwise your link will load a new page:
$(document).ready(function(){
$('.play_navigation a').click(function(e){
e.preventDefault();
console.log("this is the click");
});
});
As pointed out in comments, if your link has no href, then it's not a link, use something else.
Not working? Your code is A MESS! and ready() events everywhere... clean it, put all your scripts in ONE ready event and then try again, it will very likely sort things out.
You need to set option CURLOPT_PROXYTYPE
to CURLPROXY_SOCKS5_HOSTNAME
, which sadly wasn't defined in old PHP versions, circa pre-5.6; if you have earlier in but you can explicitly use its value, which is equal to 7
:
curl_setopt($ch, CURLOPT_PROXYTYPE, 7);
Simply use \1
instead of $1
:
In [1]: import re
In [2]: method = 'images/:id/huge'
In [3]: re.sub(r'(:[a-z]+)', r'<span>\1</span>', method)
Out[3]: 'images/<span>:id</span>/huge'
Also note the use of raw strings (r'...'
) for regular expressions. It is not mandatory but removes the need to escape backslashes, arguably making the code slightly more readable.
Control characters:
(Hex codes assume an ASCII-compatible character encoding.)
\a
= \x07
= alert (bell)\b
= \x08
= backspace\t
= \x09
= horizonal tab\n
= \x0A
= newline (or line feed)\v
= \x0B
= vertical tab\f
= \x0C
= form feed\r
= \x0D
= carriage return\e
= \x1B
= escape (non-standard GCC extension)Punctuation characters:
\"
= quotation mark (backslash not required for '"'
)\'
= apostrophe (backslash not required for "'"
)\?
= question mark (used to avoid trigraphs)\\
= backslashNumeric character references:
\
+ up to 3 octal digits\x
+ any number of hex digits\u
+ 4 hex digits (Unicode BMP, new in C++11)\U
+ 8 hex digits (Unicode astral planes, new in C++11)\0
= \00
= \000
= octal ecape for null character
If you do want an actual digit character after a \0
, then yes, I recommend string concatenation. Note that the whitespace between the parts of the literal is optional, so you can write "\0""0"
.
You can do by maintaining the state as below:
$('#user_button').on('click',function(){
if($(this).attr('data-click-state') == 1) {
$(this).attr('data-click-state', 0);
$(this).css('background-color', 'red')
}
else {
$(this).attr('data-click-state', 1);
$(this).css('background-color', 'orange')
}
});
Using UIView Extension:
extension UIView {
func addRoundedCornerToView(targetView : UIView?)
{
//UIView Corner Radius
targetView!.layer.cornerRadius = 5.0;
targetView!.layer.masksToBounds = true
//UIView Set up boarder
targetView!.layer.borderColor = UIColor.yellowColor().CGColor;
targetView!.layer.borderWidth = 3.0;
//UIView Drop shadow
targetView!.layer.shadowColor = UIColor.darkGrayColor().CGColor;
targetView!.layer.shadowOffset = CGSizeMake(2.0, 2.0)
targetView!.layer.shadowOpacity = 1.0
}
}
Usage:
override func viewWillAppear(animated: Bool) {
sampleView.addRoundedCornerToView(statusBarView)
}
JS does not have a sleep function, it has setTimeout() or setInterval() functions.
If you can move the code that you need to run after the pause into the setTimeout()
callback, you can do something like this:
//code before the pause
setTimeout(function(){
//do what you need here
}, 2000);
see example here : http://jsfiddle.net/9LZQp/
This won't halt the execution of your script, but due to the fact that setTimeout()
is an asynchronous function, this code
console.log("HELLO");
setTimeout(function(){
console.log("THIS IS");
}, 2000);
console.log("DOG");
will print this in the console:
HELLO
DOG
THIS IS
(note that DOG is printed before THIS IS)
You can use the following code to simulate a sleep for short periods of time:
function sleep(milliseconds) {
var start = new Date().getTime();
for (var i = 0; i < 1e7; i++) {
if ((new Date().getTime() - start) > milliseconds){
break;
}
}
}
now, if you want to sleep for 1 second, just use:
sleep(1000);
example: http://jsfiddle.net/HrJku/1/
please note that this code will keep your script busy for n milliseconds. This will not only stop execution of Javascript on your page, but depending on the browser implementation, may possibly make the page completely unresponsive, and possibly make the entire browser unresponsive. In other words this is almost always the wrong thing to do.
Update on March 8, 2018 with Visual Studio Code 1.20.1 (mac)
It has been simplified quite a lot lately.
Very easy and straight forward now.
From the search box just search for "editor.action.transformTo", You will see the screen like:
Click the "plus" sign at the left of each item, it will prompt dialog for your to [press] you desired key-bindings, after it showing that on the screen, just hit [Enter] to save.
One way that works pre API 11 is to start ActivityGameMain
first, then in the onCreate
of that Activity start your ActivitySplashScreen
activity. The ActivityGameMain
won't appear as you call startActivity too soon for the splash.
Then you can clear the stack when starting ActivityGameMain
by setting these flags on the Intent:
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TOP);
You also must add this to ActivitySplashScreen:
@Override
public void onBackPressed() {
moveTaskToBack(true);
}
So that pressing back on that activity doesn't go back to your ActivityGameMain
.
I assume you don't want the splash screen to be gone back to either, to achieve this I suggest setting it to noHistory
in your AndroidManifest.xml
. Then put the goBackPressed
code in your ActivitySplashScreenSignUp
class instead.
However I have found a few ways to break this. Start another app from a notification while ActivitySplashScreenSignUp
is shown and the back history is not reset.
The only real way around this is in API 11:
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TASK);
+1 means 2 days ago. It's rounded.
For Me I use the input stage param:
When a user launch a pipeline, this one will be waiting him to choose on the list choice.
pipeline{
agent any
stages{
stage('checkout scm') {
steps {
script{
git credentialsId: '8bd8-419d-8af0-30960441fcd7', url: 'ssh://[email protected]:/usr/company/repositories/repo.git'
sh 'git branch -r | awk \'{print $1}\' ORS=\'\\n\' >>branch.txt'
}
}
}
stage('get build Params User Input') {
steps{
script{
liste = readFile 'branch.txt'
echo "please click on the link here to chose the branch to build"
env.BRANCH_SCOPE = input message: 'Please choose the branch to build ', ok: 'Validate!',
parameters: [choice(name: 'BRANCH_NAME', choices: "${liste}", description: 'Branch to build?')]
}
}
}
stage("checkout the branch"){
steps{
echo "${env.BRANCH_SCOPE}"
git credentialsId: 'ea346a50-8bd8-419d-8af0-30960441fcd7', url: 'ssh://[email protected]/usr/company/repositories/repo.git'
sh "git checkout -b build ${env.BRANCH_NAME}"
}
}
stage(" exec maven build"){
steps{
withMaven(maven: 'M3', mavenSettingsConfig: 'mvn-setting-xml') {
sh "mvn clean install "
}
}
}
stage("clean workwpace"){
steps{
cleanWs()
}
}
}
}
And then user will interact withim the build :
import sys
def hello(a, b):
print 'hello and that\'s your sum: {0}'.format(a + b)
if __name__ == '__main__':
hello(int(sys.argv[1]), int(sys.argv[2]))
Moreover see @thibauts answer about how to call python script.
I realize this is an old question and has been answered but this could help someone.
In your activity

If non of the above works, just make sure you're not connected to a VPN. That's exactly what happened to me, i was connected to a VPN using Cisco AnyConnect client, also make sure you set an static DNS in the docker settings.
You need to understand that a Git repository is not just a tree of directories and files, but also stores a history of those trees - which might contain branches and merges.
When fetching from a repository, you will copy all or some of the branches there to your repository. These are then in your repository as "remote tracking branches", e.g. branches named like remotes/origin/master
or such.
Fetching new commits from the remote repository will not change anything about your local working copy.
Your working copy has normally a commit checked out, called HEAD
. This commit is usually the tip of one of your local branches.
I think you want to update your local branch (or maybe all the local branches?) to the corresponding remote branch, and then check out the latest branch.
To avoid any conflicts with your working copy (which might have local changes), you first clean everything which is not versioned (using git clean
). Then you check out the local branch corresponding to the remote branch you want to update to, and use git reset
to switch it to the fetched remote branch. (git pull
will incorporate all updates of the remote branch in your local one, which might do the same, or create a merge commit if you have local commits.)
(But then you will really lose any local changes - both in working copy and local commits. Make sure that you really want this - otherwise better use a new branch, this saves your local commits. And use git stash
to save changes which are not yet committed.)
Edit: If you have only one local branch and are tracking one remote branch, all you need to do is
git pull
from inside the working directory.
This will fetch the current version of all tracked remote branches and update the current branch (and the working directory) to the current version of the remote branch it is tracking.

where 428 was the pid of the process I'm trying to kill. It worked cleanly for me, in the absence of the hyphen '-' character. I hope it helps!
Another option, just for the heck of it would be:
if ( $('#myFav > *').length > 0 ) {
// do something
}
May actually be the fastest since it strictly uses the Sizzle engine and not necessarily any jQuery, as it were. Could be wrong though. Nevertheless, it works.
In C# 6+ you can use string interpolation and make this more terse:
$"{DateTime.UtcNow:s}Z"
As of MongoDB 2.4, you can use $setOnInsert (http://docs.mongodb.org/manual/reference/operator/setOnInsert/)
Set 'insertion_date' using $setOnInsert and 'last_update_date' using $set in your upsert command.
To turn your pseudocode into a working example:
now = datetime.utcnow()
for document in update:
collection.update_one(
{"_id": document["_id"]},
{
"$setOnInsert": {"insertion_date": now},
"$set": {"last_update_date": now},
},
upsert=True,
)
Sample solution in Python. Help taken from this video: video Like many other answers, upload id is to be retrieved from the channel id first.
import urllib.request import json key = "YOUR_YOUTUBE_API_v3_BROWSER_KEY" #List of channels : mention if you are pasting channel id or username - "id" or "forUsername" ytids = [["bbcnews","forUsername"],["UCjq4pjKj9X4W9i7UnYShpVg","id"]] newstitles = [] for ytid,ytparam in ytids: urld = "https://www.googleapis.com/youtube/v3/channels?part=contentDetails&"+ytparam+"="+ytid+"&key="+key with urllib.request.urlopen(urld) as url: datad = json.loads(url.read()) uploadsdet = datad['items'] #get upload id from channel id uploadid = uploadsdet[0]['contentDetails']['relatedPlaylists']['uploads'] #retrieve list urld = "https://www.googleapis.com/youtube/v3/playlistItems?part=snippet%2CcontentDetails&maxResults=50&playlistId="+uploadid+"&key="+key with urllib.request.urlopen(urld) as url: datad = json.loads(url.read()) for data in datad['items']: ntitle = data['snippet']['title'] nlink = data['contentDetails']['videoId'] newstitles.append([nlink,ntitle]) for link,title in newstitles: print(link, title)
UPDATE user_account student, (

WHERE teacher.user_account_id = student.teacher_id AND teacher.user_type = 'ROLE_TEACHER'
) teach SET student.student_education_facility_id= teach.teacherid WHERE student.user_type = 'ROLE_STUDENT';
you can use <pre>

mailx might help as well. From the mailx man page:

Attach the given file to the message.
Pretty easy, right?
You don't. Your array doesn't have a key [1]
. You could:
Make a new array, which contains the keys:
$newArray = array_keys($array);
echo $newArray[0];
But the value "one" is at $newArray[0]
, not [1]
.
A shortcut would be:
echo current(array_keys($array));
Get the first key of the array:
reset($array);
echo key($array);
Get the key corresponding to the value "value":
echo array_search('value', $array);
This all depends on what it is exactly you want to do. The fact is, [1]
doesn't correspond to "one" any which way you turn it.
the html:
<a class="xyz">your content</a>
the css:
.xyz{
display: block;
}
This will make the anchor be a block level element like a div.
You are asking a lot of questions that you could answer yourself by reading the documentation, so I'll give you a general advice: read it and experiment in the python shell. You'll see that itemgetter
returns a callable:
>>> func = operator.itemgetter(1)
>>> func(a)
['Paul', 22, 'Car Dealer']
>>> func(a[0])
8
To do it in a different way, you can use lambda
:
a.sort(key=lambda x: x[1])
And reverse it:
a.sort(key=operator.itemgetter(1), reverse=True)
Sort by more than one column:
a.sort(key=operator.itemgetter(1,2))
See the sorting How To.
Errr, it's a bit messy in the view. But I think I've gotten it to work with group (http://mongoid.org/docs/querying/)
Controller
@event_attendees = Activity.only(:user_id).where(:action => 'Attend').order_by(:created_at.desc).group
View
<% @event_attendees.each do |event_attendee| %>
<%= event_attendee['group'].first.user.first_name %>
<% end %>
Here's another way to force a type-cast even between incompatible types and interfaces where TS compiler normally complains:
export function forceCast<T>(input: any): T {
// ... do runtime checks here
// @ts-ignore <-- forces TS compiler to compile this as-is
return input;
}
Then you can use it to force cast objects to a certain type:
import { forceCast } from './forceCast';
const randomObject: any = {};
const typedObject = forceCast<IToDoDto>(randomObject);
Note that I left out the part you are supposed to do runtime checks before casting for the sake of reducing complexity. What I do in my project is compiling all my .d.ts
interface files into JSON schemas and using ajv
to validate in runtime.
The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.
For example,
Begin Transaction
-Do some T-SQL queries here.
Rollback transaction -- OR commit transaction
If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.
For example:
USE AdventureWorks;
GO
BEGIN TRANSACTION;
BEGIN TRY
-- Generate a constraint violation error.
DELETE FROM Production.Product
WHERE ProductID = 980;
END TRY
BEGIN CATCH
SELECT
ERROR_NUMBER() AS ErrorNumber
,ERROR_SEVERITY() AS ErrorSeverity
,ERROR_STATE() AS ErrorState
,ERROR_PROCEDURE() AS ErrorProcedure
,ERROR_LINE() AS ErrorLine
,ERROR_MESSAGE() AS ErrorMessage;
IF @@TRANCOUNT > 0
ROLLBACK TRANSACTION;
END CATCH;
IF @@TRANCOUNT > 0
COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.
I recommend using the following snippet as it works in all python versions (requires six
):
from six.moves import reload_module
reload_module(module)
You can extend jQuery functionality like this :
Extend :
(function($){
jQuery.fn.checkEmpty = function() {
return !$.trim(this.html()).length;
};
}(jQuery));
Use :
<div id="selector"></div>
if($("#selector").checkEmpty()){
console.log("Empty");
}else{
console.log("Not Empty");
}
You can use find function in your Form class. If you want to cast (Label) ,(TextView) ... etc, in this way you can use special features of objects. It will be return Label object.
(Label)this.Controls.Find(name,true)[0];
name: item name of searched item in the form
true: Search all Children boolean value
The following commands will result in printing your current working directory in a bash script.
pushd .
CURRENT_DIR="`cd $1; pwd`"
popd
echo $CURRENT_DIR
It's a very simple:
NUMOFLINES=$(cat $JAVA_TAGS_FILE | wc -l )
or
NUMOFLINES=$(wc -l $JAVA_TAGS_FILE | awk '{print $1}')
Go to your build settings and switch the target's settings to ENABLE_BITCODE = YES

EDIT Do not use this answer as it works only in some versions of Firefox. No other browsers support it. Use Gary Chambers solution.
toSource() is the function you are looking for which will write it out as JSON.
var object = {};
object.first = "test";
object.second = "test2";
alert(object.toSource());
The selected answer works, but it could use some improvement.
My solution relies on the creation of an OPTIONS variable that defines all of the options and their defaults. OPTIONS is also used to test whether a supplied option is valid. A tremendous amount of code is saved by simply storing the option values in variables named the same as the option. The amount of code is constant regardless of how many options are defined; only the OPTIONS definition has to change.
EDIT - Also, the :loop code must change if the number of mandatory positional arguments changes. For example, often times all arguments are named, in which case you want to parse arguments beginning at position 1 instead of 3. So within the :loop, all 3 become 1, and 4 becomes 2.

This solution provides Unix style arguments within a Windows batch. This is not the norm for Windows - batch usually has the options preceding the required arguments and the options are prefixed with /
.
The techniques used in this solution are easily adapted for a Windows style of options.

Update 2015-12-28: Support for !

In the code above, each argument is expanded while delayed expansion is enabled, which means that !
are most likely stripped, or else something like !var!
is expanded. In addition, ^
can also be stripped if !
is present. The following small modification to the un-commented code removes the limitation such that !

are preserved in option values.

When looking up your external IP address on a NATed host, quite a few answers suggest using HTTP based methods like ifconfig.me
eg:
$ curl ifconfig.me/ip
Over the years I have seen many of these sites come and go, I find this DNS based method more robust:
$ dig +short myip.opendns.com @resolver1.opendns.com
I have this handy alias in my ~/.bashrc
:
alias wip='dig +short myip.opendns.com @resolver1.opendns.com'
FirefoxDriver _driver = new FirefoxDriver();

Retrieve an object using the tutorial shown in the Flask-SQLAlchemy documentation. Once you have the entity that you want to change, change the entity itself. Then, db.session.commit()
.
For example:
admin = User.query.filter_by(username='admin').first()
admin.email = '[email protected]'
db.session.commit()
user = User.query.get(5)
user.name = 'New Name'
db.session.commit()
Flask-SQLAlchemy is based on SQLAlchemy, so be sure to check out the SQLAlchemy Docs as well.

You have to use System.DirectoryServices;
Here are the guts of the code
using (DirectoryEntry adsEntry = new DirectoryEntry(path, strAccountId, strPassword))

strAuthenticatedBy = "Active Directory";
strError = "User has been authenticated by Active Directory.";
}

// Failed to authenticate. Most likely it is caused by unknown user
// id or bad strPassword.
strError = ex.Message;
}

The java.sql.Timestamp class has no format. Its toString method generates a String with a format.
Do not conflate a date-time object with a String that may represent its value. A date-time object can parse strings and generate strings but is not itself a string.
First convert from the troubled old legacy date-time classes to java.time classes. Use the new methods added to the old classes.
Instant instant = mySqlDate.toInstant() ;
Lose the fraction of a second you don't want.
instant = instant.truncatedTo( ChronoUnit.Seconds );
Assign the time zone to adjust from UTC used by Instant.
ZoneId z = ZoneId.of( "America/Montreal" ) ;
ZonedDateTime zdt = instant.atZone( z );
Generate a String close to your desired output. Replace its T
in the middle with a SPACE.
DateTimeFormatter f = DateTimeFormatter.ISO_LOCAL_DATE_TIME ;
String output = zdt.format( f ).replace( "T" , " " );
I have fiddled around with this for a while and have prefer to use use read
in combination with rstrip
. Without rstrip("\n")
, Python adds a newline to the end of the string, which in most cases is not very useful.
with open("myfile.txt") as f:
file_content = f.read().rstrip("\n")
print(file_content)
I assume X
and Y
are arrays? If so, there's a very simple way to do this:
x = [1, 1, 2, 4]
y = [1, 2, 2, 2]
# intersection
x & y # => [1, 2]
# union
x | y # => [1, 2, 4]
# difference
x - y # => [4]
Specify the Line Number using NR
built-in variable.

Since the accepted BufferedInputStream#read
isn't guaranteed to read everything, rather than keeping track of the buffer sizes myself, I used this approach:
byte bytes[] = new byte[(int) file.length()];
BufferedInputStream bis = new BufferedInputStream(new FileInputStream(file));
DataInputStream dis = new DataInputStream(bis);
dis.readFully(bytes);
Blocks until a full read is complete, and doesn't require extra imports.
enum A { foo, bar } a;
a = foo;
printf( "%d", a ); // see comments below
As others pointed out, 'not possible directly'. I am guessing that you want some kind of index key for Song? Just create another field (a member variable) in Element. Increment it when you add Song to the collection.
This might be what you are looking for:
yourStream
.filter(/* your criteria */)
.findFirst()
.get();
And better, if there's a possibility of matching no element, in which case get()
will throw a NPE. So use:
yourStream
.filter(/* your criteria */)
.findFirst()
.orElse(null); /* You could also create a default object here */
public static void main(String[] args) {
class Stop {
private final String stationName;
private final int passengerCount;
Stop(final String stationName, final int passengerCount) {
this.stationName = stationName;
this.passengerCount = passengerCount;
}
}
List<Stop> stops = new LinkedList<>();
stops.add(new Stop("Station1", 250));
stops.add(new Stop("Station2", 275));
stops.add(new Stop("Station3", 390));
stops.add(new Stop("Station2", 210));
stops.add(new Stop("Station1", 190));
Stop firstStopAtStation1 = stops.stream()
.filter(e -> e.stationName.equals("Station1"))
.findFirst()
.orElse(null);
System.out.printf("At the first stop at Station1 there were %d passengers in the train.", firstStopAtStation1.passengerCount);
}
Output is:
At the first stop at Station1 there were 250 passengers in the train.
If there is a hierarchy of exceptions you can use the base class to catch all subclasses of exceptions. In the degenerate case you can catch all Java exceptions with:
try {
...
} catch (Exception e) {
someCode();
}
In a more common case if RepositoryException is the the base class and PathNotFoundException is a derived class then:
try {
...
} catch (RepositoryException re) {
someCode();
} catch (Exception e) {
someCode();
}
The above code will catch RepositoryException and PathNotFoundException for one kind of exception handling and all other exceptions are lumped together. Since Java 7, as per @OscarRyz's answer above:
try {
...
} catch( IOException | SQLException ex ) {
...
}
From Save MySQL query results into a text or CSV file:
MySQL provides an easy mechanism for writing the results of a select statement into a text file on the server. Using extended options of the INTO OUTFILE nomenclature, it is possible to create a comma separated value (CSV) which can be imported into a spreadsheet application such as OpenOffice or Excel or any other application which accepts data in CSV format.
Given a query such as
SELECT order_id,product_name,qty FROM orders
which returns three columns of data, the results can be placed into the file /tmp/orders.txt using the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.txt'
This will create a tab-separated file, each row on its own line. To alter this behavior, it is possible to add modifiers to the query:
SELECT order_id,product_name,qty FROM orders INTO OUTFILE '/tmp/orders.csv' FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n'
In this example, each field will be enclosed in double quotes, the fields will be separated by commas, and each row will be output on a new line separated by a newline (\n). Sample output of this command would look like:
"1","Tech-Recipes sock puppet","14.95" "2","Tech-Recipes chef's hat","18.95"
Keep in mind that the output file must not already exist and that the user MySQL is running as has write permissions to the directory MySQL is attempting to write the file to.
Syntax
SELECT Your_Column_Name
FROM Your_Table_Name
INTO OUTFILE 'Filename.csv'
FIELDS TERMINATED BY ','
ENCLOSED BY '"'
LINES TERMINATED BY '\n'
Or you could try to grab the output via the client:
You could try executing the query from the your local client and redirect the output to a local file destination:
mysql -user -pass -e "select cols from table where cols not null" > /tmp/output
Hint: If you don't specify an absoulte path but use something like INTO OUTFILE 'output.csv'
or INTO OUTFILE './output.csv'
, it will store the output file to the directory specified by show variables like 'datadir';

Very old question, but since google led me here I'll add a solution that I found useful:
Step 1. Create a user for each schema you need to be able to use. E.g. "user_myschema"
Step 2. Use EXECUTE AS to execute the SQL statements as the required schema user.
Step 3. Use REVERT to switch back to the original user.
Example: Let's say you have a table "mytable" present in schema "otherschema", which is not your default schema. Running "SELECT * FROM mytable" won't work.
Create a user named "user_otherschema" and set that user's default schema to be "otherschema".
Now you can run this script to interact with the table:
EXECUTE AS USER = 'user_otherschema';
SELECT * FROM mytable
REVERT
The revert statements resets current user, so you are yourself again.
Link to EXECUTE AS documentation: https://docs.microsoft.com/en-us/sql/t-sql/statements/execute-as-transact-sql?view=sql-server-2017

I had the same problem opening a CSV produced from a webservice which inserted NULL bytes in empty headers. I did the following to clean the file:
with codecs.open ('my.csv', 'rb', 'utf-8') as myfile:
data = myfile.read()
# clean file first if dirty
if data.count( '\x00' ):
print 'Cleaning...'
with codecs.open('my.csv.tmp', 'w', 'utf-8') as of:
for line in data:
of.write(line.replace('\x00', ''))
shutil.move( 'my.csv.tmp', 'my.csv' )
with codecs.open ('my.csv', 'rb', 'utf-8') as myfile:
myreader = csv.reader(myfile, delimiter=',')
# Continue with your business logic here...

MDN docs for parseInt
MDN docs for parseFloat
In parseInt radix is specified as ten so that we are in base 10. In nonstrict javascript a number prepended with 0
is treated as octal. This would obviously cause problems!
parseInt(num1, 10) + parseInt(num2, 10) //base10
parseFloat(num1) + parseFloat(num2)
Also see ChaosPandion's answer for a useful shortcut using a unary operator. I have set up a fiddle to show the different behaviors.
var ten = '10';
var zero_ten = '010';
var one = '1';
var body = document.getElementsByTagName('body')[0];
Append(parseInt(ten) + parseInt(one));
Append(parseInt(zero_ten) + parseInt(one));
Append(+ten + +one);
Append(+zero_ten + +one);
function Append(text) {
body.appendChild(document.createTextNode(text));
body.appendChild(document.createElement('br'));
}
Simple working solution:
Go here https://hub.docker.com/
to create a PRIVATE repository with name for example johnsmith/private-repository
this is the NAME/REPOSITORY
you will use for your image when building the image.
First, docker login
Second, I use "docker build -t johnsmith/private-repository:01 .
" (where 01 is my version name) to create image, and I use "docker images
" to confirm the image created such as in this yellow box below: (sorry I can not paste the table format but the text string only)
johnsmith/private-repository(REPOSITORY) 01(TAG) c5f4a2861d6e(IMAGE ID) 2 days ago(CREATED) 305MB(SIZE)
docker push johnsmith/private-repository:01
(Your private repo will be here example https://hub.docker.com/r/johnsmith/private-repository/)Done!
this work for me
git init
git add --all
3.git commit -m "name"
4.git push origin master --force
I needed to do same, but with a more complex array_filter
on the keys.
Here's how I did it, using a similar method.
// Filter out array elements with keys shorter than 4 characters
$a = array(
0 => "val 0",
"one" => "val one",
"two" => "val two",
"three"=> "val three",
"four" => "val four",
"five" => "val five",
"6" => "val 6"
);
$f = array_filter(array_keys($a), function ($k){ return strlen($k)>=4; });
$b = array_intersect_key($a, array_flip($f));
print_r($b);
This outputs the result:
Array
(
[three] => val three
[four] => val four
[five] => val five
)
First of all, the provided long code:

Now, to your question:
how to compare two elements coming from xml as string
In Xpath 1.0 strings can be compared only for equality (or inequality), using the operator =
and the function not()
together with the operator =
.
$str1 = $str2
evaluates to true()
exactly when the string $str1
is equal to the string $str2
.
not($str1 = $str2)
evaluates to true()
exactly when the string $str1
is not equal to the string $str2
.
There is also the !=
operator. It generally should be avoided because it has anomalous behavior whenever one of its operands is a node-set.
Now, the rules for comparing two element nodes are similar:
$el1 = $el2
evaluates to true()
exactly when the string value of $el1
is equal to the string value of $el2
.
not($el1 = $el2)
evaluates to true()
exactly when the string value of $el1
is not equal to the string value of $el2
.
However, if one of the operands of =
is a node-set, then
$ns = $str
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string $str
$ns1 = $ns2
evaluates to true()
exactly when there is at least one node in the node-set $ns1
, whose string value is equal to the string value of some node from $ns2
Therefore, the expression:
OU_NAME='OU_ADDR1'
evaluates to true()
only when there is at least one element child of the current node that is named OU_NAME
and whose string value is the string 'OU_ADDR1'.
This is obviously not what you want!
Most probably you want:
OU_NAME=OU_ADDR1
This expression evaluates to true
exactly there is at least one OU_NAME
child of the current node and one OU_ADDR1
child of the current node with the same string value.
Finally, in XPath 2.0, strings can be compared also using the value comparison operators lt
, le
, eq
, gt
, ge
and the inherited from XPath 1.0 general comparison operator =
.
Trying to evaluate a value comparison operator when one or both of its arguments is a sequence of more than one item results in error.
By using absolute positioning, you can make <body>
or <form>
or <div>
, fit to your browser page. For example:
<body style="position: absolute; bottom: 0px; top: 0px; left: 0px; right: 0px;">
and then simply put a <div>

or width
you wish
<div id="divContainer" style="height: 100%;">
Drawable x = getResources().getDrawable(R.drawable.x);
x.setBounds(0, 0, x.getIntrinsicWidth(), x.getIntrinsicHeight());

During app development I found that the messages come from the frequent and massive INSERT and UPDATE operations. Make sure to INSERT and UPDATE multiple rows or data in one single operation.
var updateStatementString : String! = ""
for item in cardids {
let newstring = "UPDATE "+TABLE_NAME+" SET pendingImages = '\(pendingImage)\' WHERE cardId = '\(item)\';"
updateStatementString.append(newstring)
}
print(updateStatementString)
let results = dbManager.sharedInstance.update(updateStatementString: updateStatementString)
return Int64(results)
Python 3 - UPDATED 18th November 2015
Found the accepted answer useful, yet wished to expand on several points for the benefit of others based on my own experiences.
Module: A module is a file containing Python definitions and statements. The file name is the module name with the suffix .py appended.
Module Example: Assume we have a single python script in the current directory, here I am calling it mymodule.py
The file mymodule.py contains the following code:
def myfunc():
print("Hello!")
If we run the python3 interpreter from the current directory, we can import and run the function myfunc in the following different ways (you would typically just choose one of the following):
>>> import mymodule
>>> mymodule.myfunc()
Hello!
>>> from mymodule import myfunc
>>> myfunc()
Hello!
>>> from mymodule import *
>>> myfunc()
Hello!
Ok, so that was easy enough.
Now assume you have the need to put this module into its own dedicated folder to provide a module namespace, instead of just running it ad-hoc from the current working directory. This is where it is worth explaining the concept of a package.
Package: Packages are a way of structuring Python’s module namespace by using “dotted module names”. For example, the module name A.B designates a submodule named B in a package named A. Just like the use of modules saves the authors of different modules from having to worry about each other’s global variable names, the use of dotted module names saves the authors of multi-module packages like NumPy or the Python Imaging Library from having to worry about each other’s module names.
Package Example: Let's now assume we have the following folder and files. Here, mymodule.py is identical to before, and __init__.py is an empty file:
.
+-- mypackage
+-- __init__.py
+-- mymodule.py
The __init__.py files are required to make Python treat the directories as containing packages. For further information, please see the Modules documentation link provided later on.
Our current working directory is one level above the ordinary folder called mypackage
$ ls
mypackage
If we run the python3 interpreter now, we can import and run the module mymodule.py containing the required function myfunc in the following different ways (you would typically just choose one of the following):
>>> import mypackage
>>> from mypackage import mymodule
>>> mymodule.myfunc()
Hello!
>>> import mypackage.mymodule
>>> mypackage.mymodule.myfunc()
Hello!
>>> from mypackage import mymodule
>>> mymodule.myfunc()
Hello!
>>> from mypackage.mymodule import myfunc
>>> myfunc()
Hello!
>>> from mypackage.mymodule import *
>>> myfunc()
Hello!
Assuming Python 3, there is excellent documentation at: Modules
In terms of naming conventions for packages and modules, the general guidelines are given in PEP-0008 - please see Package and Module Names
Modules should have short, all-lowercase names. Underscores can be used in the module name if it improves readability. Python packages should also have short, all-lowercase names, although the use of underscores is discouraged.
Also, make sure that the java version used at runtime is an equivalent or later version than the java used during compilation
I eventually stumbled upon an example of the usage I was looking for - to assign an error to the Model in general, rather than one of it's properties, as usual you call:
ModelState.AddModelError(string key, string errorMessage);
but use an empty string for the key:
ModelState.AddModelError(string.Empty, "There is something wrong with Foo.");
The error message will present itself in the <%: Html.ValidationSummary() %>
as you'd expect.
Knockout.js validation is handy but it is not robust. You always have to create server side validation replica. In your case (as you use knockout.js) you are sending JSON data to server and back asynchronously, so you can make user think that he sees client side validation, but in fact it would be asynchronous server side validation.
Take a look at example here upida.cloudapp.net:8080/org.upida.example.knockout/order/create?clientId=1 This is a "Create Order" link. Try to click "save", and play with products. This example is done using upida library (there are spring mvc version and asp.net mvc of this library) from codeplex.

You can force the use of TCP instead of shared memory, either by prefixing tcp: to the server name in the connection string, or by using localhost.
Have you considered applying ON DELETE CASCADE
where relevant?
It's the directory where java
was run from, where you started the JVM. Does not have to be within the user's home directory. It can be anywhere where the user has permission to run java.
So if you cd
into /somedir
, then run your program, user.dir
will be /somedir
.
A different property, user.home
, refers to the user directory. As in /Users/myuser
or /home/myuser
or C:\Users\myuser
.
See here for a list of system properties and their descriptions.

For http connections, the WebRequest and WebResponse classes use SSL to communicate with web hosts that support SSL. The decision to use SSL is made by the WebRequest class, based on the URI it is given. If the URI begins with "https:", SSL is used; if the URI begins with "http:", an unencrypted connection is used.

Here is a trick if you want to calculate maximum(field, 0):

Your rewrite rule looks almost ok.
First make sure that your .htaccess
file is in your document root (the same place as index.php
) or it'll only affect the sub-folder it's in (and any sub-folders within that - recursively).
Next make a slight change to your rule so it looks something like:
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /index.php?path=$1 [NC,L,QSA]
At the moment you're just matching on .
which is one instance of any character, you need at least .*
to match any number of instances of any character.
The $_GET['path']
variable will contain the fake directory structure, so /mvc/module/test
for instance, which you can then use in index.php to determine the Controller and actions you want to perform.
If you want the whole shebang installed in a sub-directory, such as /mvc/
or /framework/
the least complicated way to do it is to change the rewrite rule slightly to take that into account.
RewriteRule ^(.*)$ /mvc/index.php?path=$1 [NC,L,QSA]
And ensure that your index.php
is in that folder whilst the .htaccess
file is in the document root.
Alternative to $_GET['path']
(updated Feb '18 and Jan '19)
It's not actually necessary (nor even common now) to set the path as a $_GET
variable, many frameworks will rely on $_SERVER['REQUEST_URI']
to retrieve the same information - normally to determine which Controller to use - but the principle is exactly the same.
This does simplify the RewriteRule
slightly as you don't need to create the path parameter (which means the OP's original RewriteRule
will now work):
RewriteEngine on
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^.*$ /index.php [L,QSA]
However, the rule about installing in a sub-directory still applies, e.g.
RewriteRule ^.*$ /mvc/index.php [L,QSA]
The flags:
NC
= No Case (not case sensitive, not really necessary since there are no characters in the pattern)
L
= Last (it'll stop rewriting at after this Rewrite so make sure it's the last thing in your list of rewrites)
QSA
= Query String Append, just in case you've got something like ?like=penguins
on the end which you want to keep and pass to index.php.
Strangely enough, I don't think there is a standard solution to this problem, as the spring-security access control is expression based, not java-based. you might check the source code for DefaultMethodSecurityExpressionHandler to see if you can re-use something they are doing there
Function Pointers can have very different sizes, from 4 to 20 Bytes on an X86 machine, depending on the compiler. So the answer is NO - sizes can vary.
Another example: take an 8051 program, it has three memory ranges and thus has three different pointer sizes, from 8 bit, 16bit, 24bit, depending on where the target is located, even though the target's size is always the same (e.g. char).
The console.log
should be wrapped in a function , the "default" function for every class is its constructor
so it should be declared there.
import { Component } from '@angular/core';
console.log("Hello1");
@Component({
selector: 'hello-console',
})
export class App {
s: string = "Hello2";
constructor(){
console.log(s);
}
}
The issue is due to the missing python3.dll
file in Anaconda3.
To fix the issue, you should simply copy the python3.dll
to C:\Program Files\Anaconda3
(or wherever your Anaconda3 is installed).
You can get the python3.dll
by downloading the binaries provided at the bottom of the Python's Release page and extracting the python3.dll
from the ZIP file.
You can do this easily by using the library cryptocode
. Here is how you install:
pip install cryptocode
Encrypting a message (example code):
import cryptocode
encoded = cryptocode.encrypt("mystring","mypassword")
## And then to decode it:
decoded = cryptocode.decrypt(encoded, "mypassword")

I usually add separate
safe pipe
reusable component as following
# Add Safe Pipe
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer } from '@angular/platform-browser';
@Pipe({name: 'mySafe'})
export class SafePipe implements PipeTransform {
constructor(private sanitizer: DomSanitizer) {
}
public transform(url) {
return this.sanitizer.bypassSecurityTrustResourceUrl(url);
}
}
# then create shared pipe module as following
import { NgModule } from '@angular/core';
import { SafePipe } from './safe.pipe';
@NgModule({
declarations: [
SafePipe
],
exports: [
SafePipe
]
})
export class SharedPipesModule {
}
# import shared pipe module in your native module
@NgModule({
declarations: [],
imports: [
SharedPipesModule,
],
})
export class SupportModule {
}

call your url (`trustedUrl` for me) and add `mySafe` as defined in Safe Pipe
---------------->
<div class="container-fluid" *ngIf="trustedUrl">
<iframe [src]="trustedUrl | mySafe" align="middle" width="100%" height="800" frameborder="0"></iframe>

Include stdlib.h
in your header, and then call abort();
in any place you want to exit your program. Like this:
switch(varName)
{
case 1:
blah blah;
case 2:
blah blah;
case 3:
abort();
}
When the user enters the switch accepts this and give it to the case 3 where you call the abort
function. It will exit your screen immediately after hitting enter key.

I started using the AngiesList.Redis.RedisSessionStateModule, which aside from using the (very fast) Redis server for storage (I'm using the windows port -- though there is also an MSOpenTech port), it does absolutely no locking on the session.
In my opinion, if your application is structured in a reasonable way, this is not a problem. If you actually need locked, consistent data as part of the session, you should specifically implement a lock/concurrency check on your own.
MS deciding that every ASP.NET session should be locked by default just to handle poor application design is a bad decision, in my opinion. Especially because it seems like most developers didn't/don't even realize sessions were locked, let alone that apps apparently need to be structured so you can do read-only session state as much as possible (opt-out, where possible).

I am adding the framework to find multiple words and negate those from dataFrame.
Here 'word1','word2','word3','word4'
= list of patterns to search
df
= DataFrame
column_a
= A column name from from DataFrame df
Search_for_These_values = ['word1','word2','word3','word4']
pattern = '|'.join(Search_for_These_values)
result = df.loc[~(df['column_a'].str.contains(pattern, case=False)]
Or you can use the command line below from version 4.4.x.
conda config --set proxy_servers.http http://id:pw@address:port
conda config --set proxy_servers.https https://id:pw@address:port
For those wanting a more secure way to create a random byte array, yes the most secure way is:
byte[] bytes = new byte[20];
SecureRandom.getInstanceStrong().nextBytes(bytes);
BUT your threads might block if there is not enough randomness available on the machine, depending on your OS. The following solution will not block:
SecureRandom random = new SecureRandom();
byte[] bytes = new byte[20];
random.nextBytes(bytes);
This is because the first example uses /dev/random
and will block while waiting for more randomness (generated by a mouse/keyboard and other sources). The second example uses /dev/urandom
which will not block.
make
is a GNU command so the only way you can get it on Windows is installing a Windows version like the one provided by GNUWin32. Anyway, there are several options for getting that:
C:\MinGW\bin\mingw32-make.exe
. Otherwise you're missing the mingw32-make additional utilities
. Look for the link at MinGW's HowTo page to get it installed. Once you've got it, you have two choices:1.1 Copy the MinGW make executable to make.exe
:
copy c:\MinGW\bin\mingw32-make.exe c:\MinGW\bin\make.exe
1.2 Create a link to the actual executable, in your PATH. In this case, if you update MinGW, the link is not deleted:
mklink c:\bin\make.exe C:\MinGW\bin\mingw32-make.exe
Other option is using Chocolatey. First you need to install this package manager. Once installed you simlpy need to install make
:
choco install make
Last option is installing a Windows Subsystem for Linux (WSL), so you'll have a Linux distribution of your choice embedded in Windows 10 where you'll be able to install make
, gcc
and all the tools you need to build C programs.
WebDriver driver = new ff / chrome / anyDriverYouWish();
driver.manage().timeouts().implicitlyWait(10, TimeUnit.SECONDS);
Waits maximum of 10 Seconds.
WebDriverWait wait = new WebDriverWait(driver, 10);
wait.until(ExpectedConditions.visibilityOf(WebElement element));
FluentWait<Driver> fluentWait;
fluentWait = new FluentWait<>(driver).withTimeout(30, TimeUnit.SECONDS)
.pollingEvery(200, TimeUnit.MILLISECONDS)
.ignoring(NoSuchElementException.class);
The advantage of the last option is that you can include exception to be expected, so that your execution continues.

The best answer here:
https://www.git-tower.com/learn/git/glossary/origin
In Git, "origin" is a shorthand name for the remote repository that a project was originally cloned from. More precisely, it is used instead of that original repository's URL - and thereby makes referencing much easier.
its just simple
select * from myTable where year(columnX) = 2010
This query stands good for fetching the values between current date and its next 3 dates
SELECT * FROM tableName
WHERE columName BETWEEN CURDATE() AND DATE_ADD(CURDATE(), INTERVAL 3 DAY)
This will eventually add extra 3 days of buffer to the current date.
A little late reply, but what I found in Notepad++ v7.8.6 is, on RMB (Right Mouse Button), on selection text, it gives an option called "Style token" where it shows "Using 1st/2nd/3rd/4th/5th style" to highlight the selected text in different pre-defined colors
Here's the most concise way I've found (using capybara 3.3.0 and chromium driver):
all('#id-of-select option')[1].select_option
will select the 2nd option. Increment the index as needed.
It feels pretty hacky, but I managed to get the correct look by adding an extra column and row beyond what is needed. Then I filled the extra column with a Space in each row defining a height and filled the extra row with a Space in each col defining a width. For extra flexibility, I imagine these Space sizes could be set in code to provide something similar to weights. I tried to add a screenshot, but I do not have the reputation necessary.

On SQL Server 2012, you can use the following stored procedure:
sp_columns '<table name>'
For example, given a database table named users:
sp_columns 'users'
A lot of the answers here were written prior to Roslyn (the open-source .NET C# and VB compilers) moving to .NET 4.6. So they won't help you if your project targets, say, 4.5.2 as mine did (inherited and can't be changed).
But you can grab a previous version of Roslyn from https://www.nuget.org/packages/Microsoft.Net.Compilers and install that instead of the latest version. I used 1.3.2. (I tried 2.0.1 - which appears to be the last version that runs on .NET 4.5 - but I couldn't get it to compile*.) Run this from the Package Manager console in VS 2013:
PM> Install-Package Microsoft.Net.Compilers -Version 1.3.2
Then restart Visual Studio. I had a couple of problems initially; you need to set the C# version back to default (C#6.0 doesn't appear in the version list but seems to have been made the default), then clean, save, restart VS and recompile.
Interestingly, I didn't have any IntelliSense errors due to the C#6.0 features used in the code (which were the reason for wanting C#6.0 in the first place).
* version 2.0.1 threw error The "Microsoft.CodeAnalysis.BuildTasks.Csc task could not be loaded from the assembly Microsoft.Build.Tasks.CodeAnalysis.dll. Could not load file or assembly 'Microsoft.Build.Utilities.Core, Version=14.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a' or one of its dependencies. The system cannot find the file specified. Confirm that the declaration is correct, that the assembly and all its dependencies are available, and that the task contains a public class that implements Microsoft.Build.Framework.ITask.
UPDATE One thing I've noticed since posting this answer is that if you change any code during debug ("Edit and Continue"), you'll like find that your C#6.0 code will suddenly show as errors in what seems to revert to a pre-C#6.0 environment. This requires a restart of your debug session. VERY annoying especially for web applications.
var pdf = MyPdf.pdf;
window.open(pdf);
This will open the pdf document in a full window from JavaScript
A function to open windows would look like this:
function openPDF(pdf){
window.open(pdf);
return false;
}
It works for me. Your data
object is probably nil
and, as rckoenes noted, the root object should be a (mutable) array. See this code:
NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *e = nil;
NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"%@", json);
(I had to escape the quotes in the JSON string with backslashes.)
The reason the first code sample doesn't work is because the layout of the page changed. As per the warning on that page: "The translated string is fetched by the RegEx close to the bottom. This could of course change, and you have to keep it up to date." I think this should work for now, at least until they change the page again.
public string TranslateText(string input, string languagePair)
{
string url = String.Format("http://www.google.com/translate_t?hl=en&ie=UTF8&text={0}&langpair={1}", input, languagePair);
WebClient webClient = new WebClient();
webClient.Encoding = System.Text.Encoding.UTF8;
string result = webClient.DownloadString(url);
result = result.Substring(result.IndexOf("<span title=
\"") + "<span title=
\"".Length);
result = result.Substring(result.IndexOf(">") + 1);
result = result.Substring(0, result.IndexOf("</span
>"));
return result.Trim();
}
The ad-hoc profile doesn't support debugging. You need to debug with a Development profile, and use the Ad-Hoc profile only for distributing non-debuggable copies.
I removed bin
from the CLASSPATH
. I found out that I was executing the java
command from the directory where the HelloWorld.java
is located, i.e.:
C:\Users\xyz\Documents\Java\javastudy\src\org\tij\exercises>java HelloWorld
So I moved back to the main directory and executed:
java org.tij.exercises.HelloWorld
and it worked, i.e.:
C:\Users\xyz\Documents\Java\javastudy\src>java org.tij.exercises.HelloWorld

If X

you should be able to use
List<Y> listOfY = listOfX.Cast<Y>().ToList();

.For encoding to base64 in Angular2, you can use btoa() function.
Example:-
console.log(btoa("stringAngular2"));
// Output:- c3RyaW5nQW5ndWxhcjI=
For decoding from base64 in Angular2, you can use atob() function.
Example:-
console.log(atob("c3RyaW5nQW5ndWxhcjI="));
// Output:- stringAngular2
Arrays.asList(factors)
returns a List<int[]>
, not a List<Integer>
. Since you're doing new ArrayList
instead of new ArrayList<Integer>
you don't get a compile error for that, but create an ArrayList<Object>
which contains an int[]
and you then implicitly cast that arraylist to ArrayList<Integer>
. Of course the first time you try to use one of those "Integers" you get an exception.
Classic javascript mistake.
setTimeout(function(){this.setState({timePassed: true})}, 1000)
When setTimeout
runs this.setState
, this
is no longer CowtanApp
, but window
. If you define the function with the =>
notation, es6 will auto-bind this
.
setTimeout(() => {this.setState({timePassed: true})}, 1000)
Alternatively, you could use a let that = this;
at the top of your render
, then switch your references to use the local variable.
render() {
let that = this;
setTimeout(function(){that.setState({timePassed: true})}, 1000);
If not working, use bind
.
setTimeout(
function() {
this.setState({timePassed: true});
}
.bind(this),
1000
);
My solution, may be helpful.

In addition to John's answer, and reading up on Lodash (which I had hitherto regarded as a "me-too" to Underscore.js), and seeing the performance tests, reading the source-code, and blog posts, the few points which make Lodash much superior to Underscore.js are these:
If you look into Underscore.js's source-code, you'll see in the first few lines that Underscore.js falls-back on the native implementations of many functions. Although in an ideal world, this would have been a better approach, if you look at some of the performance links given in these slides, it is not hard to draw the conclusion that the quality of those 'native implementations' vary a lot browser-to-browser. Firefox is damn fast in some of the functions, and in some Chrome dominates. (I imagine there would be some scenarios where Internet Explorer would dominate too). I believe that it's better to prefer a code whose performance is more consistent across browsers.
Do read the blog post earlier, and instead of believing it for its sake, judge for yourself by running the benchmarks. I am stunned right now, seeing a Lodash performing 100-150% faster than Underscore.js in even simple, native functions such as
Array.every
in Chrome!
Here is a list of differences between Lodash, and it's Underscore.js build is a drop-in replacement for your Underscore.js projects.
I'm late to the party here, but there's an awesome library I've been using which I haven't seen referenced in the other answers
https://github.com/brminnick/AsyncAwaitBestPractices
If you need to "Fire And Forget" you call the extension method on the task.
Passing the action onException to the call ensures that you get the best of both worlds - no need to await execution and slow your users down, whilst retaining the ability to handle the exception in a graceful manner.
In your example you would use it like this:
public string GetStringData()
{
MyAsyncMethod().SafeFireAndForget(onException: (exception) =>
{
//DO STUFF WITH THE EXCEPTION
});
return "hello world";
}
It also gives awaitable AsyncCommands implementing ICommand out the box which is great for my MVVM Xamarin solution
have you tried with a condition in ng-class like here : http://jsfiddle.net/DotDotDot/zvLvg/ ?
<span id='1' ng-class='{"myclass":tog==1}' ng-click='tog=1'>span 1</span>
<span id='2' ng-class='{"myclass":tog==2}' ng-click='tog=2'>span 2</span>
Yahoo uses a method called Sender ID, which can be configured at The SPF Setup Wizard and entered in to your DNS. Also one of the important ones for Exchange, Hotmail, AOL, Yahoo, and others is to have a Reverse DNS for your domain. Those will knock out most of the issues. However you can never prevent a person intentionally blocking your or custom rules.
If you want to get a list of files that are only in one directory and not their sub directories and only their file names:
diff -q /dir1 /dir2 | grep /dir1 | grep -E "^Only in*" | sed -n 's/[^:]*: //p'
If you want to recursively list all the files and directories that are different with their full paths:
diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}'
This way you can apply different commands to all the files.
For example I could remove all the files and directories that are in dir1 but not dir2:
diff -rq /dir1 /dir2 | grep -E "^Only in /dir1*" | sed -n 's/://p' | awk '{print $3"/"$4}' xargs -I {} rm -r {}
If you're talking MS SQL, here's the most efficient way. This retrieves the current identity seed from a table based on whatever column is the identity.
select IDENT_CURRENT('TableName') as LastIdentity
Using MAX(id)
is more generic, but for example I have an table with 400 million rows that takes 2 minutes to get the MAX(id)
. IDENT_CURRENT
is nearly instantaneous...
You shouldn't use ForEach
in that way. Read Lippert's “foreach” vs “ForEach”
If you want to be cruel with yourself (and the world), at least don't create useless List
employees.All(p => {
collection.AddRange(p.Departments);
p.Departments.All(u => { u.SomeProperty = null; return true; } );
return true;
});
Note that the result of the All
expression is a bool
value that we are discarding (we are using it only because it "cycles" all the elements)
I'll repeat. You shouldn't use ForEach
to change objects. LINQ should be used in a "functional" way (you can create new objects but you can't change old objects nor you can create side-effects). And what you are writing is creating so many useless List
only to gain two lines of code...

Coming at this almost a year later, there's a different manner in which I solved my particular problem. Since I wanted the link to be handled by my own app, there is a solution that is a bit simpler.
Besides the default intent filter, I simply let my target activity listen to ACTION_VIEW
intents, and specifically, those with the scheme com.package.name
<intent-filter>
<category android:name="android.intent.category.DEFAULT" />
<action android:name="android.intent.action.VIEW" />
<data android:scheme="com.package.name" />
</intent-filter>
This means that links starting with com.package.name://
will be handled by my activity.
So all I have to do is construct a URL that contains the information I want to convey:
com.package.name://action-to-perform/id-that-might-be-needed/
In my target activity, I can retrieve this address:
Uri data = getIntent().getData();
In my example, I could simply check data
for null values, because when ever it isn't null, I'll know it was invoked by means of such a link. From there, I extract the instructions I need from the url to be able to display the appropriate data.

If you set HOME
to c:\my_configuration_files\
, then git will locate .gitconfig there. Editing environment variables is described here. You need to set the HOME variable, then re-open any cmd.exe window. Use the "set" command to verify that HOME indeed points to the right value.
Changing HOME will, of course, also affect other applications. However, from reading git's source code, that appears to be the only way to change the location of these files without the need to adjust the command line. You should also consider Stefan's response: you can set the GIT_CONFIG variable. However, to give it the effect you desire, you need to pass the --global
flag to all git invocations (plus any local .git/config files are ignored).

Here's my effort to give a more complete answer (building on @john's answer).
The initial issue I encountered was changing the width and height of a canvas node (using styles), resulted in the contents just being "zoomed" or "shrunk." This was not the desired effect.
So, say you want to draw two rectangles of arbitrary size in a canvas that is 100px by 100px.
<canvas width="100" height="100"></canvas>
To ensure that the rectangles will not exceed the size of the canvas and therefore not be visible, you need to ensure that the canvas is big enough.
var $canvas = $('canvas'),
oldCanvas,
context = $canvas[0].getContext('2d');
function drawRects(x, y, width, height)
{
if (($canvas.width() < x+width) || $canvas.height() < y+height)
{
oldCanvas = $canvas[0].toDataURL("image/png")
$canvas[0].width = x+width;
$canvas[0].height = y+height;
var img = new Image();
img.src = oldCanvas;
img.onload = function (){
context.drawImage(img, 0, 0);
};
}
context.strokeRect(x, y, width, height);
}
drawRects(5,5, 10, 10);
drawRects(15,15, 20, 20);
drawRects(35,35, 40, 40);
drawRects(75, 75, 80, 80);

I disagree with the accepted answer being "the easiest", particularly if you want to use virtualenv.
You can use the Unofficial Windows Binaries instead. Download the appropriate wheel from there, and install it with pip
:
pip install pywin32-219-cp27-none-win32.whl
(Make sure you pick the one for the right version and bitness of Python).
You might be able to get the URL and install it via pip
without downloading it first, but they're made it a bit harder to just grab the URL. Probably better to download it and host it somewhere yourself.
This is not code golf, but here is my shortest trick, using types.SimpleNamespace
as the container for JSON objects.
Compared to the leading namedtuple
solution, it is:
rename
option, and probably the same limitation on keys that are not valid identifiers (uses setattr
under the covers)Example:
from __future__ import print_function
import json
try:
from types import SimpleNamespace as Namespace
except ImportError:
# Python 2.x fallback
from argparse import Namespace
data = '{"name": "John Smith", "hometown": {"name": "New York", "id": 123}}'
x = json.loads(data, object_hook=lambda d: Namespace(**d))
print (x.name, x.hometown.name, x.hometown.id)
Different types to check the values exists
d = {"key1":"value1", "key2":"value2"}
"value10" in d.values()
>> False
What if list of values
test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6']}
"value4" in [x for v in test.values() for x in v]
>>True
What if list of values with string values
test = {'key1': ['value4', 'value5', 'value6'], 'key2': ['value9'], 'key3': ['value6'], 'key5':'value10'}
values = test.values()
"value10" in [x for v in test.values() for x in v] or 'value10' in values
>>True

I encountered a similar problem while using Sourcetree with newly created files (they wouldnt be included in the stash either).
When I first chose 'stage all' and then stash the newly added components where tracked and therefore included in the stash.
As ExpandoObject
inherits the IDictionary<string, object>
you can use the following check
dynamic myVariable = GetDataThatLooksVerySimilarButNotTheSame();
if (((IDictionary<string, object>)myVariable).ContainsKey("MyProperty"))
//Do stuff
You can make a utility method to perform this check, that will make the code much cleaner and re-usable
Python don't have a great support for recursion because of it's lack of TRE (Tail Recursion Elimination).
This means that each call to your recursive function will create a function call stack and because there is a limit of stack depth (by default is 1000) that you can check out by sys.getrecursionlimit
(of course you can change it using sys.setrecursionlimit but it's not recommended) your program will end up by crashing when it hits this limit.
As other answer has already give you a much nicer way for how to solve this in your case (which is to replace recursion by simple loop) there is another solution if you still want to use recursion which is to use one of the many recipes of implementing TRE in python like this one.
N.B: My answer is meant to give you more insight on why you get the error, and I'm not advising you to use the TRE as i already explained because in your case a loop will be much better and easy to read.
You can Try using :- git ls-files -s
The reason could be that the summation exceeded the required number of digits - 4. If you increase the size of the decimal to decimal(10,2)
, it should work
SELECT SUM(convert(decimal(10,2), Stuff)) as result FROM table
OR
SELECT SUM(CAST(Stuff AS decimal(6,2))) as result FROM table
If you define the ListView
in XAML:
<ListView x:Name="listView"/>
Then you can add columns and populate it in C#:
public Window()
{
// Initialize
this.InitializeComponent();
// Add columns
var gridView = new GridView();
this.listView.View = gridView;
gridView.Columns.Add(new GridViewColumn {
Header = "Id", DisplayMemberBinding = new Binding("Id") });
gridView.Columns.Add(new GridViewColumn {
Header = "Name", DisplayMemberBinding = new Binding("Name") });
// Populate list
this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}
See definition of MyItem
below.
However, it's easier to define the columns in XAML (inside the ListView
definition):
<ListView x:Name="listView">
<ListView.View>
<GridView>
<GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
<GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
</GridView>
</ListView.View>
</ListView>
And then just populate the list in C#:
public Window()
{
// Initialize
this.InitializeComponent();
// Populate list
this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}
See definition of MyItem
below.

is defined like this:
public class MyItem
{
public int Id { get; set; }
public string Name { get; set; }

If you want to get the friends list from Facebook, you need to submit your app for review in Facebook. See some of the Login Permissions:
Here are the two steps:
1) First your app status is must be in Live
2) Get required permissions form Facebook.
Go to the apps page and select your app
Select status in the top right in Dashboard.
Submit privacy policy URL
Select category
Now our app is in Live status.
One step is completed.
First send required requests.
Example: user_friends, user_videos, user_posts, etc.
Second, go to the Current Request page
Example: user_events
Submit all details
Like this submit for all requests (user_friends , user_events, user_videos, user_posts, etc.).
Finally submit your app for review.
If your review is accepted from Facebook's side, you are now eligible to read contacts, etc.
Simpler way:

Tip: send to /dev/null
if you want command's exit status, but not outputs.
If you map to an array of Promises, you can then resolve them all to an array of numbers. See Promise.all.
Move pod members to a base class to shorten your initializer list:
struct foo_pod
{
int x;
int y;
int z;
};
struct foo : foo_pod
{
std::string name;
foo(std::string name)
: foo_pod()
, name(name)
{
}
};
int main()
{
foo f("bar");
printf("%d %d %d %s\n", f.x, f.y, f.z, f.name.c_str());
}
Use ALTER TABLE
with DROP COLUMN
to drop a column from a table, and CHANGE
or MODIFY
to change a column.
ALTER TABLE tbl_Country DROP COLUMN IsDeleted;
ALTER TABLE tbl_Country MODIFY IsDeleted tinyint(1) NOT NULL;
ALTER TABLE tbl_Country CHANGE IsDeleted IsDeleted tinyint(1) NOT NULL;
In Python 3 you can overwrite print function with default set to flush = True
def print(*objects, sep=' ', end='\n', file=sys.stdout, flush=True):
__builtins__.print(*objects, sep=sep, end=end, file=file, flush=flush)
The download from java.com
which installs in /Library/Internet Plug-Ins
is only the JRE, for development you probably want to download the JDK from http://www.oracle.com/technetwork/java/javase/downloads/index.html and install that instead. This will install the JDK at /Library/Java/JavaVirtualMachines/jdk1.7.0_<something>.jdk/Contents/Home
which you can then add to Eclipse via Preferences -> Java -> Installed JREs.
Try below android studio plugin
HOW TO
Github Link: https://github.com/pedrovgs/AndroidWiFiADB
NOTE: Remember that your device and your computer have to be in the same WiFi connection.
You want something like:
<appSettings>
<add key="developmentModeUserId" xdt:Transform="Remove" xdt:Locator="Match(key)"/>
<add key="developmentMode" value="false" xdt:Transform="SetAttributes"
xdt:Locator="Match(key)"/>
</appSettings>

All the tools you would need are already available to you on most modern distributions of Linux.
As several have pointed out you can pipe the serial data through netcat. However you would need to relaunch a new instance each time there is a connection. In order to have this persist between connections you can create a xinetd service using the following configuration:
service testservice
{
port = 5900
socket_type = stream
protocol = tcp
wait = yes
user = root
server = /usr/bin/netcat
server_args = "-l 5900 < /dev/ttyS0"
}
Be sure to change the /dev/ttyS0
to match the serial device you are attempting to interface with.
Note: this solution only works for short distances.
I tried to use dommer's posted formula for an application and found it did well for long distances but in my data I was using all very short distances, and dommer's post did very poorly. I needed speed, and the more complex geo calcs worked well but were too slow. So, in the case that you need speed and all the calculations you're making are short (maybe < 100m or so). I found this little approximation to work great. it assumes the world is flat mind you, so don't use it for long distances, it works by approximating the distance of a single Latitude and Longitude at the given Latitude and returning the Pythagorean distance in meters.
public class FlatEarthDist {
//returns distance in meters
public static double distance(double lat1, double lng1,
double lat2, double lng2){
double a = (lat1-lat2)*FlatEarthDist.distPerLat(lat1);
double b = (lng1-lng2)*FlatEarthDist.distPerLng(lat1);
return Math.sqrt(a*a+b*b);
}
private static double distPerLng(double lat){
return 0.0003121092*Math.pow(lat, 4)
+0.0101182384*Math.pow(lat, 3)
-17.2385140059*lat*lat
+5.5485277537*lat+111301.967182595;
}
private static double distPerLat(double lat){
return -0.000000487305676*Math.pow(lat, 4)
-0.0033668574*Math.pow(lat, 3)
+0.4601181791*lat*lat
-1.4558127346*lat+110579.25662316;
}
}
On IIS hosted sites, try recycling the app pool. It fixed my issue. Thanks
If I want tranfer only the response variable y instead of a linear model with x specified, eg I wanna transfer/normalize a list of data, I can take 1 for x, then the object becomes a linear model:
library(MASS)
y = rf(500,30,30)
hist(y,breaks = 12)
result = boxcox(y~1, lambda = seq(-5,5,0.5))
mylambda = result$x[which.max(result$y)]
mylambda
y2 = (y^mylambda-1)/mylambda
hist(y2)
