If you want your PATH variable to correctly update based on your current working directory, add this to the end of your .bashrc
-equivalent (or after anything that defines PATH
):
__OLD_PATH=$PATH
function updatePATHForNPM() {
export PATH=$(npm bin):$__OLD_PATH
}
function node-mode() {
PROMPT_COMMAND=updatePATHForNPM
}
function node-mode-off() {
unset PROMPT_COMMAND
PATH=$__OLD_PATH
}
# Uncomment to enable node-mode by default:
# node-mode
This may add a short delay every time the bash prompt gets rendered (depending on the size of your project, most likely), so it's disabled by default.
You can enable and disable it within your terminal by running node-mode
and node-mode-off
, respectively.
$('#submit').click(function(){
if($('#myMessage').val() == ''){
alert('Input can not be left blank');
}
});
Update
If you don't want whitespace also u can remove them using jQuery.trim()
Description: Remove the whitespace from the beginning and end of a string.
$('#submit').click(function(){
if($.trim($('#myMessage').val()) == ''){
alert('Input can not be left blank');
}
});
You need to implement RefreshTokenProvider. First create class for RefreshTokenProvider ie.
public class ApplicationRefreshTokenProvider : AuthenticationTokenProvider
{
public override void Create(AuthenticationTokenCreateContext context)
{
// Expiration time in seconds
int expire = 5*60;
context.Ticket.Properties.ExpiresUtc = new DateTimeOffset(DateTime.Now.AddSeconds(expire));
context.SetToken(context.SerializeTicket());
}
public override void Receive(AuthenticationTokenReceiveContext context)
{
context.DeserializeTicket(context.Token);
}
}
Then add instance to OAuthOptions.
OAuthOptions = new OAuthAuthorizationServerOptions
{
TokenEndpointPath = new PathString("/authenticate"),
Provider = new ApplicationOAuthProvider(),
AccessTokenExpireTimeSpan = TimeSpan.FromSeconds(expire),
RefreshTokenProvider = new ApplicationRefreshTokenProvider()
};
It tells the browser to read the css file as UTF-8. This is handy if your CSS contains unicode characters and not only ASCII.
Using it in the meta tag is fine, but only for pages that include that meta tag.
Read about the rules for character set resolution of CSS files at the w3c spec for CSS 2.
In Rails 4 you could do:
GroupMember.find_or_create_by(member_id: 4, group_id: 7)
And use where
is different:
GroupMember.where(member_id: 4, group_id: 7).first_or_create
This will call create
on GroupMember.where(member_id: 4, group_id: 7)
:
GroupMember.where(member_id: 4, group_id: 7).create
On the contrary, the find_or_create_by(member_id: 4, group_id: 7)
will call create
on GroupMember
:
GroupMember.create(member_id: 4, group_id: 7)
Please see this relevant commit on rails/rails.
Just a little comment from my side since the OBJECT_ID
doesn't work for me. It always returns that
`#tempTable doesn't exist
..even though it does exist. I just found it's stored with different name (postfixed by _
underscores) like so :
#tempTable________
This works well for me:
IF EXISTS(SELECT [name] FROM tempdb.sys.tables WHERE [name] like '#tempTable%') BEGIN
DROP TABLE #tempTable;
END;
All of the examples here (with the exception of rockacola's) require that the user physically click on the window to define focus. This isn't ideal, so .hover()
is the better choice:
$(window).hover(function(event) {
if (event.fromElement) {
console.log("inactive");
} else {
console.log("active");
}
});
This'll tell you when the user has their mouse on the screen, though it still won't tell you if it's in the foreground with the user's mouse elsewhere.

Also $( "#container" ).find( "div.robotarm" );
is equal to: $( "div.robotarm", "#container" )

If you have a custom struct or class and want to sort them arbitrarily, you should call sort() using a trailing closure that sorts on a field you specify. Here's an example using an array of custom structs that sorts on a particular property:
struct User {
var firstName: String
}
var users = [
User(firstName: "Jemima"),
User(firstName: "Peter"),
User(firstName: "David"),
User(firstName: "Kelly"),
User(firstName: "Isabella")
]
users.sort {
$0.firstName < $1.firstName
}
If you want to return a sorted array rather than sort it in place, use sorted() like this:
let sortedUsers = users.sorted {
$0.firstName < $1.firstName
}
The element.style
property lets you know only the CSS properties that were defined as inline in that element (programmatically, or defined in the style attribute of the element), you should get the computed style.
Is not so easy to do it in a cross-browser way, IE has its own way, through the element.currentStyle
property, and the DOM Level 2 standard way, implemented by other browsers is through the document.defaultView.getComputedStyle
method.
The two ways have differences, for example, the IE element.currentStyle
property expect that you access the CCS property names composed of two or more words in camelCase (e.g. maxHeight
, fontSize
, backgroundColor
, etc), the standard way expects the properties with the words separated with dashes (e.g. max-height
, font-size
, background-color
, etc).
Also, the IE element.currentStyle
will return all the sizes in the unit that they were specified, (e.g. 12pt, 50%, 5em), the standard way will compute the actual size in pixels always.
I made some time ago a cross-browser function that allows you to get the computed styles in a cross-browser way:
function getStyle(el, styleProp) {
var value, defaultView = (el.ownerDocument || document).defaultView;
// W3C standard way:
if (defaultView && defaultView.getComputedStyle) {
// sanitize property name to css notation
// (hypen separated words eg. font-Size)
styleProp = styleProp.replace(/([A-Z])/g, "-$1").toLowerCase();
return defaultView.getComputedStyle(el, null).getPropertyValue(styleProp);
} else if (el.currentStyle) { // IE
// sanitize property name to camelCase
styleProp = styleProp.replace(/\-(\w)/g, function(str, letter) {
return letter.toUpperCase();
});
value = el.currentStyle[styleProp];
// convert other units to pixels on IE
if (/^\d+(em|pt|%|ex)?$/i.test(value)) {
return (function(value) {
var oldLeft = el.style.left, oldRsLeft = el.runtimeStyle.left;
el.runtimeStyle.left = el.currentStyle.left;
el.style.left = value || 0;
value = el.style.pixelLeft + "px";
el.style.left = oldLeft;
el.runtimeStyle.left = oldRsLeft;
return value;
})(value);
}
return value;
}
}
The above function is not perfect for some cases, for example for colors, the standard method will return colors in the rgb(...) notation, on IE they will return them as they were defined.
I'm currently working on an article in the subject, you can follow the changes I make to this function here.
Try using an empty collapse argument within the paste function:
paste(sdata, collapse = '')
You can also do
console.log("a = %o, b = %o", a, b);
where a and b are objects.
As the definition of Linkedlist says, it is a sequence and you are guaranteed to get the elements in order.
eg:
import java.util.LinkedList;
public class ForEachDemonstrater {
public static void main(String args[]) {
LinkedList<Character> pl = new LinkedList<Character>();
pl.add('j');
pl.add('a');
pl.add('v');
pl.add('a');
for (char s : pl)
System.out.print(s+"->");
}
}
Same thing as mine on OS X Mavericks.
After a couple of trials by error while changing Apache configuration, I got weird output on localhost/xampp. Thought PHP engine was messed up. However, 127.0.0.1/xampp is working completely okay.
Finally, I cleaned up the browser cache and reload the page again and Voila!
Resolved on Firefox...
Yes, it is possible and you have answered it! About good practises, I think it is better to launch commands from files and not directly from your code. So you have to make Java execute the list of commands (or one command) in an existing .bat
, .sh
, .ksh
... files.
Here is an example of executing a list of commands in a file MyFile.sh
:
String[] cmd = { "sh", "MyFile.sh", "\pathOfTheFile"};
Runtime.getRuntime().exec(cmd);
Webpack
is a bundler. Like Browserfy
it looks in the codebase for module requests (require
or import
) and resolves them recursively. What is more, you can configure Webpack
to resolve not just JavaScript-like modules, but CSS, images, HTML, literally everything. What especially makes me excited about Webpack
, you can combine both compiled and dynamically loaded modules in the same app. Thus one get a real performance boost, especially over HTTP/1.x. How exactly you you do it I described with examples here http://dsheiko.com/weblog/state-of-javascript-modules-2017/
As an alternative for bundler one can think of Rollup.js
(https://rollupjs.org/), which optimizes the code during compilation, but stripping all the found unused chunks.
For AMD
, instead of RequireJS
one can go with native ES2016 module system
, but loaded with System.js
(https://github.com/systemjs/systemjs)
Besides, I would point that npm
is often used as an automating tool like grunt
or gulp
. Check out https://docs.npmjs.com/misc/scripts. I personally go now with npm scripts only avoiding other automation tools, though in past I was very much into grunt
. With other tools you have to rely on countless plugins for packages, that often are not good written and not being actively maintained. npm
knows its packages, so you call to any of locally installed packages by name like:
{
"scripts": {
"start": "npm http-server"
},
"devDependencies": {
"http-server": "^0.10.0"
}
}
Actually you as a rule do not need any plugin if the package supports CLI.
You could use the DateTime class built in PHP. It has a method called "add", and how it is used is thoroughly demonstrated in the manual: http://www.php.net/manual/en/datetime.add.php
It however requires PHP 5.3.0.
You shouldn't put a ListView inside a ScrollView because the ListView class implements its own scrolling and it just doesn't receive gestures because they all are handled by the parent ScrollView
MessageBox.Show also returns a DialogResult, which if you put some buttons on there, means you can have it returned what the user clicked. Most of the time I write something like
if (MessageBox.Show("Do you want to continue?", "Question", MessageBoxButtons.YesNo) == MessageBoxResult.Yes) {
//some interesting behaviour here
}
which I guess is a bit unwieldy but it gets the job done.
See https://docs.microsoft.com/en-us/dotnet/api/system.windows.forms.dialogresult for additional enum options you can use here.
It's simple I think you can just say
#define NAME JACK
#if NAME == queen
You can use this on iOS 5.0 and later: This no longer works.
[[UIApplication sharedApplication] openURL:[NSURL URLWithString:@"prefs://"]];
Your image is actually upside down. But it has a meta attribute "Orientation" which tells the viewer it should be the rotated 180 degrees. Some devices/viewers don't obey this rule.
Open it in Chrome: right way up Open it in FF: right way up Open it in IE: upside down
Open it in Paint: Upside down Open it in Photoshop: Right way up. etc.
I think an example of the case that has caught me by surprise is relevant:
var myObject = { name: "Cody", status: "Surprised" };
for (var propertyName in myObject) {
document.writeln( propertyName + " : " + myObject[propertyName] );
}
But to my surprise, the output is
name : Cody
status : Surprised
forEach : function (obj, callback) {
for (prop in obj) {
if (obj.hasOwnProperty(prop) && typeof obj[prop] !== "function") {
callback(prop);
}
}
}
Why? Another script on the page has extended the Object prototype:
Object.prototype.forEach = function (obj, callback) {
for ( prop in obj ) {
if ( obj.hasOwnProperty( prop ) && typeof obj[prop] !== "function" ) {
callback( prop );
}
}
};
Go to Menu-Tab -> Project -> Build -> Automatically(check this option). and than reopen a new project.
You may try the following:
System.Globalization.CultureInfo cultureinfo =
new System.Globalization.CultureInfo("nl-NL");
DateTime dt = DateTime.Parse(date, cultureinfo);
If you mean you want the pull to overwrite local changes, doing the merge as if the working tree were clean, well, clean the working tree:
git reset --hard
git pull
If there are untracked local files you could use git clean
to remove them. Use git clean -f
to remove untracked files, -df
to remove untracked files and directories, and -xdf
to remove untracked or ignored files or directories.
If on the other hand you want to keep the local modifications somehow, you'd use stash to hide them away before pulling, then reapply them afterwards:
git stash
git pull
git stash pop
I don't think it makes any sense to literally ignore the changes, though - half of pull is merge, and it needs to merge the committed versions of content with the versions it fetched.
All string functions as lower
, upper
, strip
are returning a string without modifying the original. If you try to modify a string, as you might think well it is an iterable
, it will fail.
x = 'hello'
x[0] = 'i' #'str' object does not support item assignment
There is a good reading about the importance of strings being immutable: Why are Python strings immutable? Best practices for using them
make it so easy.

Check the partition where you have installed docker. In most cases, the partition is at 100% capacity so you may need to look into that.
If you are redirecting with PHP, then you would simply use the sleep() command to sleep for however many seconds before redirecting.
But, I think what you are referring to is the meta refresh tag:
http://webdesign.about.com/od/metataglibraries/a/aa080300a.htm
In modern MongoDB releases you can brute force this with $slice
just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push
to an array.
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$project": {
"books": { "$slice": [ "$books", 2 ] },
"count": 1
}}
])
Still not resolving SERVER-9377, but in this release $lookup
allows a new "non-correlated" option which takes an "pipeline"
expression as an argument instead of the "localFields"
and "foreignFields"
options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit
in order to return the "top-n" results.
db.books.aggregate([
{ "$group": {
"_id": "$addr",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$lookup": {
"from": "books",
"let": {
"addr": "$_id"
},
"pipeline": [
{ "$match": {
"$expr": { "$eq": [ "$addr", "$$addr"] }
}},
{ "$group": {
"_id": "$book",
"count": { "$sum": 1 }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
],
"as": "books"
}}
])
The other addition here is of course the ability to interpolate the variable through $expr
using $match
to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit
each result separately.
This would be the next best option to running parallel queries, and actually would be better if the $match
were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push
" as the referenced issue asks, it actually delivers something that should work better.
You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 }
])
Now that will give you a result like this:
{
"result" : [
{
"_id" : "address1",
"books" : [
{
"book" : "book4",
"count" : 1
},
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 3
}
],
"count" : 5
},
{
"_id" : "address2",
"books" : [
{
"book" : "book5",
"count" : 1
},
{
"book" : "book1",
"count" : 2
}
],
"count" : 3
}
],
"ok" : 1
}
So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.
This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:
db.books.aggregate([
{ "$group": {
"_id": {
"addr": "$addr",
"book": "$book"
},
"bookCount": { "$sum": 1 }
}},
{ "$group": {
"_id": "$_id.addr",
"books": {
"$push": {
"book": "$_id.book",
"count": "$bookCount"
},
},
"count": { "$sum": "$bookCount" }
}},
{ "$sort": { "count": -1 } },
{ "$limit": 2 },
{ "$unwind": "$books" },
{ "$sort": { "count": 1, "books.count": -1 } },
{ "$group": {
"_id": "$_id",
"books": { "$push": "$books" },
"count": { "$first": "$count" }
}},
{ "$project": {
"_id": {
"_id": "$_id",
"books": "$books",
"count": "$count"
},
"newBooks": "$books"
}},
{ "$unwind": "$newBooks" },
{ "$group": {
"_id": "$_id",
"num1": { "$first": "$newBooks" }
}},
{ "$project": {
"_id": "$_id",
"newBooks": "$_id.books",
"num1": 1
}},
{ "$unwind": "$newBooks" },
{ "$project": {
"_id": "$_id",
"num1": 1,
"newBooks": 1,
"seen": { "$eq": [
"$num1",
"$newBooks"
]}
}},
{ "$match": { "seen": false } },
{ "$group":{
"_id": "$_id._id",
"num1": { "$first": "$num1" },
"num2": { "$first": "$newBooks" },
"count": { "$first": "$_id.count" }
}},
{ "$project": {
"num1": 1,
"num2": 1,
"count": 1,
"type": { "$cond": [ 1, [true,false],0 ] }
}},
{ "$unwind": "$type" },
{ "$project": {
"books": { "$cond": [
"$type",
"$num1",
"$num2"
]},
"count": 1
}},
{ "$group": {
"_id": "$_id",
"count": { "$first": "$count" },
"books": { "$push": "$books" }
}},
{ "$sort": { "count": -1 } }
])
So that will actually give you the top 2 "books" from the top two "address" entries.
But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.
The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await
syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

Several answers show dangerous examples. OP's example [ $a == $b ]
specifically used unquoted variable substitution (as of Oct '17 edit). For [...]
that is safe for string equality.
But if you're going to enumerate alternatives like [[...]]
, you must inform also that the right-hand-side must be quoted. If not quoted, it is a pattern match! (From bash man page: "Any part of the pattern may be quoted to force it to be matched as a string.").
Here in bash, the two statements yielding "yes" are pattern matching, other three are string equality:
$ rht="A*"
$ lft="AB"
$ [ $lft = $rht ] && echo yes
$ [ $lft == $rht ] && echo yes
$ [[ $lft = $rht ]] && echo yes
yes
$ [[ $lft == $rht ]] && echo yes
yes
$ [[ $lft == "$rht" ]] && echo yes

This is better than Application.Username

Application Username

Yes, you can simulate a mouse click by creating an event and dispatching it:
function click(x,y){
var ev = document.createEvent("MouseEvent");
var el = document.elementFromPoint(x,y);
ev.initMouseEvent(
"click",
true /* bubble */, true /* cancelable */,
window, null,
x, y, 0, 0, /* coordinates */
false, false, false, false, /* modifier keys */
0 /*left*/, null
);
el.dispatchEvent(ev);
}
Beware of using the click
method on an element -- it is widely implemented but not standard and will fail in e.g. PhantomJS. I assume jQuery's implemention of .click()
does the right thing but have not confirmed.
If the undefined's are implicit then you can do:
var len = 0;
for (var i in arr) { len++ };
undefined's are implicit if you don't set them explicitly
//both are a[0] and a[3] are explicit undefined
var arr = [undefined, 1, 2, undefined];
arr[6] = 3;
//now arr[4] and arr[5] are implicit undefined
delete arr[1]
//now arr[1] is implicit undefined
arr[2] = undefined
//now arr[2] is explicit undefined
if your form contains an input field like
<input type='text' id='id1' />
then you can write the code in javascript as given below to set its value as
document.getElementById('id1').value='text to be displayed' ;

#define VA_ARGS_NUM_PRIV(P1, P2, P3, P4, P5, P6, Pn, ...) Pn
#define VA_ARGS_NUM(...) VA_ARGS_NUM_PRIV(-1, ##__VA_ARGS__, 5, 4, 3, 2, 1, 0)
VA_ARGS_NUM() ==> 0
VA_ARGS_NUM(19) ==> 1
VA_ARGS_NUM(9, 10) ==> 2
...
On many devices (such as the iPhone), it prevents the user from using the browser's zoom. If you have a map and the browser does the zooming, then the user will see a big ol' pixelated image with huge pixelated labels. The idea is that the user should use the zooming provided by Google Maps. Not sure about any interaction with your plugin, but that's what it's there for.
More recently, as @ehfeng notes in his answer, Chrome for Android (and perhaps others) have taken advantage of the fact that there's no native browser zooming on pages with a viewport tag set like that. This allows them to get rid of the dreaded 300ms delay on touch events that the browser takes to wait and see if your single touch will end up being a double touch. (Think "single click" and "double click".) However, when this question was originally asked (in 2011), this wasn't true in any mobile browser. It's just added awesomeness that fortuitously arose more recently.
That's how I've done it in angular2 (it is similar to that plunkered solution) In your HTML file:
<div id="print-section">
// your html stuff that you want to print
</div>
<button (click)="print()">print</button>
and in your TS file :
print(): void {
let printContents, popupWin;
printContents = document.getElementById('print-section').innerHTML;
popupWin = window.open('', '_blank', 'top=0,left=0,height=100%,width=auto');
popupWin.document.open();
popupWin.document.write(`
<html>
<head>
<title>Print tab</title>
<style>
//........Customized style.......
</style>
</head>
<body onload="window.print();window.close()">${printContents}</body>
</html>`
);
popupWin.document.close();
}
You can also shortcut the path and use merely ngx-print library for less inconsistent coding (mixing JS and TS) and more out-of-the-box controllable and secured printing cases.
str.replace(/replacetext/g,'actualtext')
This replaces all instances of replacetext
with actualtext
You're probably returning an object that's on the stack. That is, return_Object()
probably looks like this:
Object& return_Object()
{
Object object_to_return;
// ... do stuff ...
return object_to_return;
}
If this is what you're doing, you're out of luck - object_to_return
has gone out of scope and been destructed at the end of return_Object
, so myObject
refers to a non-existent object. You either need to return by value, or return an Object
declared in a wider scope or new
ed onto the heap.
This regex is very short and sweet for working.
/^([+]\d{2})?\d{10}$/
Ex: +910123456789 or 0123456789
-> /^ and $/ is for starting and ending
-> The ? mark is used for conditional formatting where before question mark is available or not it will work
-> ([+]\d{2}) this indicates that the + sign with two digits '\d{2}' here you can place digit as per country
-> after the ? mark '\d{10}' this says that the digits must be 10 of length change as per your country mobile number length
This is how this regex for mobile number is working.
+ sign is used for world wide matching of number.
if you want to add the space between than you can use the
[ ]
here the square bracket represents the character sequence and a space is character for searching in regex.
for the space separated digit you can use this regex
/^([+]\d{2}[ ])?\d{10}$/
Ex: +91 0123456789

The function you're after is numpy.linalg.norm
. (I reckon it should be in base numpy as a property of an array -- say x.norm()
-- but oh well).
import numpy as np
x = np.array([1,2,3,4,5])
np.linalg.norm(x)
You can also feed in an optional ord
for the nth order norm you want. Say you wanted the 1-norm:
np.linalg.norm(x,ord=1)
And so on.
Because you tried to access an element in a collection, using a numeric index that exceeds the collection's boundaries.
The first element in a collection is generally located at index 0
. The last element is at index n-1
, where n
is the Size
of the collection (the number of elements it contains). If you attempt to use a negative number as an index, or a number that is larger than Size-1
, you're going to get an error.
When you declare an array like this:
var array = new int[6]
The first and last elements in the array are
var firstElement = array[0];
var lastElement = array[5];
So when you write:
var element = array[5];
you are retrieving the sixth element in the array, not the fifth one.
Typically, you would loop over an array like this:
for (int index = 0; index < array.Length; index++)
{
Console.WriteLine(array[index]);
}
This works, because the loop starts at zero, and ends at Length-1
because index
is no longer less than Length
.
This, however, will throw an exception:
for (int index = 0; index <= array.Length; index++)
{
Console.WriteLine(array[index]);
}
Notice the <=
there? index
will now be out of range in the last loop iteration, because the loop thinks that Length
is a valid index, but it is not.
Lists work the same way, except that you generally use Count
instead of Length
. They still start at zero, and end at Count - 1
.
for (int index = 0; i < list.Count; index++)
{
Console.WriteLine(list[index]);
}
However, you can also iterate through a list using foreach
, avoiding the whole problem of indexing entirely:
foreach (var element in list)
{
Console.WriteLine(element.ToString());
}
You cannot index an element that hasn't been added to a collection yet.
var list = new List<string>();
list.Add("Zero");
list.Add("One");
list.Add("Two");
Console.WriteLine(list[3]); // Throws exception.
And I got this exception for including one can.js script inside another, e.g.,
{{>anotherScript}}
This should be (condition)? True statement : False statement
Leave out the "if"
Assuming you just need to reverse an indexed array (not associative or multidimensional) a simple for loop would suffice:
$fruits = ['bananas', 'apples', 'pears'];
for($i = count($fruits)-1; $i >= 0; $i--) {
echo $fruits[$i] . '<br>';
}
for (i,j) in [(i,j) for i in range(x) for j in range(y)]
should do it.
If you are in a SharePoint Page just use:
_spPageContextInfo.userId;
import java.util.Scanner;
class CalculateGCD
{
public static int calGCD(int a, int b)
{
int c=0,d=0;
if(a>b){c=b;}
else{c=a;}
for(int i=c; i>0; i--)
{
if(((a%i)+(b%i))==0)
{
d=i;
break;
}
}
return d;
}
public static void main(String args[])
{
Scanner sc=new Scanner(System.in);
System.out.println("Enter the nos whose GCD is to be calculated:");
int a=sc.nextInt();
int b=sc.nextInt();
System.out.println(calGCD(a,b));
}
}
In a terminal window, you can type:
kill -9 $(ps -p $PPID -o ppid=)
This will kill the Terminal application process, which is the parent of the parent of the current process, as seen by the kill command.
To close a Terminal window from within a running script, you need to go up one more level in the process hierarchy like this:
kill -9 $(ps -p $(ps -p $PPID -o ppid=) -o ppid=)
For my database duplicated(keep=False) did not work until the column was sorted.
data.sort_values(by=['Order ID'], inplace=True)
df = data[data['Order ID'].duplicated(keep=False)]
If you want to change the size of plot the use arg figsize
df.groupby(['NFF', 'ABUSE']).size().unstack()
.plot(kind='bar', stacked=True, figsize=(15, 5))
Remove the semicolon after hello
int i=1;
while (true) {
WebElementdisplay=driver.findElement(By.id("__bar"+i+"-btnGo"));
System.out.println(display);
if (display.isDisplayed()==true)
{
System.out.println("inside if statement"+i);
driver.findElement(By.id("__bar"+i+"-btnGo")).click();
break;
}
else
{
System.out.println("inside else statement"+ i);
i=i+1;
}
}
You can use this code it works fine.
var pinImage = new google.maps.MarkerImage("http://www.googlemapsmarkers.com/v1/009900/");
var marker = new google.maps.Marker({
position: yourlatlong,
icon: pinImage,
map: map
});
In your java class, set the "EditText
" Type to "TextView
". Because you have declared a TextView
in the layout.xml
file

I am using following code to decode base64 string in node API nodejs version 10.7.0
let data = 'c3RhY2thYnVzZS5jb20='; // Base64 string
let buff = new Buffer(data, 'base64'); //Buffer
let text = buff.toString('ascii'); //this is the data type that you want your Base64 data to convert to
console.log('"' + data + '" converted from Base64 to ASCII is "' + text + '"');
Please don't try to run above code in console of the browser, won't work. Put the code in server side files of nodejs. I am using above line code in API development.
You need a bindingsource object to act as an intermediary and assist in the binding. Then instead of updating the user interface, update the underlining model.
var model = (Fruit) bindingSource1.DataSource;
model.FruitType = "oranges";
bindingSource.ResetBindings();
Read up on BindingSource and simple data binding for Windows Forms.
When the page loads totally (dom, images, ...)
$(window).load(function(){
// full load
});
When DOM elements load (not necessary all images will be loaded)
$(function(){
// DOM Ready
});
Then you can trigger any event
$("element").trigger("event");
You can create a function that returns a boolean value and checks every attribute. You can call that function to do the job for you.
Alternatively, you can initialize the object with default values. That way there is no need for you to do any checking.
I think the only way to do this is to run another machine in parallel and use that machine to issue commands to your android box similar to how you would with a phone. If you have issues with the IP changing you can reserve an ip on your router and have the machine grab that one instead of asking the routers DHCP for one. This way you can ping the machine and figure out if it's done rebooting to continue the script.
Using LINQ to xml if you are using framework 3.5:
using System.Xml.Linq;
XDocument xmlFile = XDocument.Load("books.xml");
var query = from c in xmlFile.Elements("catalog").Elements("book")
select c;
foreach (XElement book in query)
{
book.Attribute("attr1").Value = "MyNewValue";
}
xmlFile.Save("books.xml");
Even better idea for this. You can do like this too

It's worth mentioning the -p
flag here ("p" for pretend).
If you add this to the command it will simply do a "test" run and show you what files will be deleted without actually deleting them.
$ rails d controller welcome -p
remove app/controllers/welcome_controller.rb
invoke erb
remove app/views/welcome
invoke test_unit
remove test/controllers/welcome_controller_test.rb
invoke helper
remove app/helpers/welcome_helper.rb
invoke test_unit
remove test/helpers/welcome_helper_test.rb
invoke assets
invoke coffee
remove app/assets/javascripts/welcome.js.coffee
invoke scss
remove app/assets/stylesheets/welcome.css.scss
If you're happy with it, run the command again without the -p
flag.

I was facing the same issue because i have done some changes in my develop branch and then want to go to the profile branch. so i have stash the changes by
git stash
then in profile branch i have also done some changes and then want to come back again to the develop so i have to stash the changes again by
git stash
but when i come to develop branch and tried to git the stash changes by
git stash apply
so i was getting error need merge
to solve this issue first i have to check the stash list by
git stash list
so it shows the list of stashes in my case there were 2 stashes the name of the stashes are displaying like this stash@{0},stash@{1}
I have need changes from stash@{1} so when i try to get it by this command
git stash apply stash@{1}
so was getting error needs merge
so now to solve this issue check the status of your files
git status
so it was giving error that "both modified" so to solve this run
git add .
it will add the missing modified files now again check the status
git status
so now there is no error now can apply stash
git stash apply stash@{1}
you can do this process for any number of stash files.
Try,
# cat test.sh
#!/bin/bash
/bin/touch file.txt
cron as:
* * * * * /bin/sh /home/myUser/scripts/test.sh
And you can confirm this by:
# tailf /var/log/cron
pass value of parameter like this
data : $('#form_id').serialize() + "¶meter1=value1¶meter2=value2"
and so on.
In Git, to "fast forward" means to update the HEAD
pointer in such a way that its new value is a direct descendant of the prior value. In other words, the prior value is a parent, or grandparent, or grandgrandparent, ...
Fast forwarding is not possible when the new HEAD
is in a diverged state relative to the stream you want to integrate. For instance, you are on master
and have local commits, and git fetch
has brought new upstream commits into origin/master
. The branch now diverges from its upstream and cannot be fast forwarded: your master
HEAD
commit is not an ancestor of origin/master
HEAD
. To simply reset master
to the value of origin/master
would discard your local commits. The situation requires a rebase or merge.
If your local master
has no changes, then it can be fast-forwarded: simply updated to point to the same commit as the latestorigin/master
. Usually, no special steps are needed to do fast-forwarding; it is done by merge
or rebase
in the situation when there are no local commits.
Is it ok to assume that fast-forward means all commits are replayed on the target branch and the HEAD is set to the last commit on that branch?
No, that is called rebasing, of which fast-forwarding is a special case when there are no commits to be replayed (and the target branch has new commits, and the history of the target branch has not been rewritten, so that all the commits on the target branch have the current one as their ancestor.)

I just implemented this bit of jQuery to show and hide bootstrap modal values. Different fields are displayed based on the value range of a users textbox entry.
$(document).ready(function () {
jQuery.noConflict();
var Ammount = document.getElementById('Ammount');
$("#addtocart").click(function () {
if ($(Ammount).val() >= 250 && $(Ammount).val() <= 499) {
{
$('#myModal').modal();
$("#myModalLabelbronze").show();
$("#myModalLabelsilver").hide();
$("#myModalLabelgold").hide();
$("#myModalPbronze").show();
$("#myModalPSilver").hide();
$("#myModalPGold").hide();
}
}
});
I can't find a scenario that cannot be solved using node-fibers. The example you provided using node-fibers behaves as expected. The key is to run all the relevant code inside a fiber, so you don't have to start a new fiber in random positions.
Lets see an example: Say you use some framework, which is the entry point of your application (you cannot modify this framework). This framework loads nodejs modules as plugins, and calls some methods on the plugins. Lets say this framework only accepts synchronous functions, and does not use fibers by itself.
There is a library that you want to use in one of your plugins, but this library is async, and you don't want to modify it either.
The main thread cannot be yielded when no fiber is running, but you still can create plugins using fibers! Just create a wrapper entry that starts the whole framework inside a fiber, so you can yield the execution from the plugins.
Downside: If the framework uses setTimeout
or Promise
s internally, then it will escape the fiber context. This can be worked around by mocking setTimeout
, Promise.then
, and all event handlers.
So this is how you can yield a fiber until a Promise
is resolved. This code takes an async (Promise returning) function and resumes the fiber when the promise is resolved:
framework-entry.js
console.log(require("./my-plugin").run());
async-lib.js
exports.getValueAsync = () => {
return new Promise(resolve => {
setTimeout(() => {
resolve("Async Value");
}, 100);
});
};
my-plugin.js
const Fiber = require("fibers");
function fiberWaitFor(promiseOrValue) {
var fiber = Fiber.current, error, value;
Promise.resolve(promiseOrValue).then(v => {
error = false;
value = v;
fiber.run();
}, e => {
error = true;
value = e;
fiber.run();
});
Fiber.yield();
if (error) {
throw value;
} else {
return value;
}
}
const asyncLib = require("./async-lib");
exports.run = () => {
return fiberWaitFor(asyncLib.getValueAsync());
};
my-entry.js
require("fibers")(() => {
require("./framework-entry");
}).run();
When you run node framework-entry.js
it will throw an error: Error: yield() called with no fiber running
. If you run node my-entry.js
it works as expected.
You can use a LinearLayout
instead of using Button
it's an arrangement i used in my app
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_margin="20dp"
android:background="@color/mainColor"
android:orientation="horizontal"
android:padding="10dp">
<ImageView
android:layout_width="50dp"
android:layout_height="50dp"
android:background="@drawable/ic_cv"
android:textColor="@color/offBack"
android:textSize="20dp" />
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_margin="10dp"
android:text="@string/cartyCv"
android:textColor="@color/offBack"
android:textSize="25dp" />
</LinearLayout>
In Windows, you could use:
const std::wstring hex = L"0x13";
const std::wstring dec = L"19";
int ret;
if (StrToIntEx(hex.c_str(), STIF_SUPPORT_HEX, &ret)) {
std::cout << ret << "\n";
}
if (StrToIntEx(dec.c_str(), STIF_SUPPORT_HEX, &ret)) {
std::cout << ret << "\n";
}
strtol
,stringstream
need to specify the base if you need to interpret hexdecimal.
You can also use MDIParent-child form. Set the child form's parent as MDI Parent
Eg
child.MdiParent = parentForm;
child.Show();
In this case just 1 form will be shown and the child forms will come inside the parent. Hope this helps
In cases wherein the width/height of the space is beyond
I usually use:
For horizontal spacer:
<span style="display:inline-block; width: YOURWIDTH;"></span>
For vertical spacer:
<span style="display:block; height: YOURHEIGHT;"></span>
There is a minimal amount of "default" buffer when you startup a 'screen' session within your 'putty session'. I use screens a lot in my work, so I can tell you that you will not have a combination of 'screen' buffer & 'putty' buffer within your 'screen' session.
Setting the default number of scrollback lines by adding defscrollback 10000
to your ~/.screenrc
file is the correct solution.
By the way, I use "defscrollback 200000" in my ./screenrc
file.
git push
doesn't push all of your local branches: how would it know which remote branches to push them to? It only pushes local branches which have been configured to push to a particular remote branch.
On my version of Git (1.6.5.3), when I run git remote show origin
it actually prints out which branches are configured for push:
Local refs configured for 'git push':
master pushes to master (up to date)
quux pushes to quux (fast forwardable)
Q. But I could push to master
without worrying about all this!
When you git clone
, by default it sets up your local master
branch to push to the remote's master
branch (locally referred to as origin/master
), so if you only commit on master
, then a simple git push
will always push your changes back.
However, from the output snippet you posted, you're on a branch called develop
, which I'm guessing hasn't been set up to push to anything. So git push
without arguments won't push commits on that branch.
When it says "Everything up-to-date", it means "all the branches you've told me how to push are up to date".
Q. So how can I push my commits?
If what you want to do is put your changes from develop
into origin/master
, then you should probably merge them into your local master
then push that:
git checkout master
git merge develop
git push # will push 'master'
If what you want is to create a develop
branch on the remote, separate from master
, then supply arguments to git push
:
git push origin develop
That will: create a new branch on the remote called develop
; and bring that branch up to date with your local develop
branch; and set develop
to push to origin/develop
so that in future, git push
without arguments will push develop
automatically.
If you want to push your local develop
to a remote branch called something other than develop
, then you can say:
git push origin develop:something-else
However, that form won't set up develop
to always push to origin/something-else
in future; it's a one-shot operation.
You say it's not working. What are you expecting to happen?
There's no way of getting the data out of a FormData
object; it's just intended for you to use to send data along with an XMLHttpRequest
object (for the send
method).
Update almost five years later: In some newer browsers, this is no longer true and you can now see the data provided to FormData
in addition to just stuffing data into it. See the accepted answer for more info.
Bind variable can be used in Oracle SQL query with "in" clause.
Works in 10g; I don't know about other versions.
Bind variable is varchar up to 4000 characters.
Example: Bind variable containing comma-separated list of values, e.g.
:bindvar = 1,2,3,4,5
select * from mytable
where myfield in
(
SELECT regexp_substr(:bindvar,'[^,]+', 1, level) items
FROM dual
CONNECT BY regexp_substr(:bindvar, '[^,]+', 1, level) is not null
);

Having struggled with ImageIO
a lot in the past years, I think Andrew Taylor's solution is by far the best compromise (fast: not using ImageIO#read
, and versatile). Thanks man!!
But I was a little frustrated to be compelled to use a local file (File/String), especially in cases where you want to check image sizes coming from, say, a multipart/form-data request where you usually retrieve InputPart
/InputStream
's. So I quickly made a variant that accepts File
, InputStream
and RandomAccessFile
, based on the ability of ImageIO#createImageInputStream
to do so.
Of course, such a method with Object input
, may only remain private and you shall create as many polymorphic methods as needed, calling this one. You can also accept Path
with Path#toFile()
and URL
with URL#openStream()
prior to passing to this method:
private static Dimension getImageDimensions(Object input) throws IOException {
try (ImageInputStream stream = ImageIO.createImageInputStream(input)) { // accepts File, InputStream, RandomAccessFile
if(stream != null) {
IIORegistry iioRegistry = IIORegistry.getDefaultInstance();
Iterator<ImageReaderSpi> iter = iioRegistry.getServiceProviders(ImageReaderSpi.class, true);
while (iter.hasNext()) {
ImageReaderSpi readerSpi = iter.next();
if (readerSpi.canDecodeInput(stream)) {
ImageReader reader = readerSpi.createReaderInstance();
try {
reader.setInput(stream);
int width = reader.getWidth(reader.getMinIndex());
int height = reader.getHeight(reader.getMinIndex());
return new Dimension(width, height);
} finally {
reader.dispose();
}
}
}
throw new IllegalArgumentException("Can't find decoder for this image");
} else {
throw new IllegalArgumentException("Can't open stream for this image");
}
}
}
There are different ways to achieve underlined text in an Android TextView.
1.<u>This is my underlined text</u>
or
I just want to underline <u>this</u> word
2.You can do the same programmatically.
`textView.setPaintFlags(textView.getPaintFlags() | Paint.UNDERLINE_TEXT_FLAG);`
3.It can be done by creating a SpannableString and then setting it as the TextView text property
SpannableString text = new SpannableString("Voglio sottolineare solo questa parola");
text.setSpan(new UnderlineSpan(), 25, 6, 0);
textView.setText(text);
The six library helps with writing code that is compatible with both python 2.5+ and python 3. It has an iteritems method that will work in both python 2 and 3. Example:
import six
d = dict( foo=1, bar=2 )
for k, v in six.iteritems(d):
print(k, v)
Yes, it is a non-type parameter. You can have several kinds of template parameters
What you have there is of the last kind. It's a compile time constant (so-called constant expression) and is of type integer or enumeration. After looking it up in the standard, i had to move class templates up into the types section - even though templates are not types. But they are called type-parameters for the purpose of describing those kinds nonetheless. You can have pointers (and also member pointers) and references to objects/functions that have external linkage (those that can be linked to from other object files and whose address is unique in the entire program). Examples:
Template type parameter:
template<typename T>
struct Container {
T t;
};
// pass type "long" as argument.
Container<long> test;
Template integer parameter:
template<unsigned int S>
struct Vector {
unsigned char bytes[S];
};
// pass 3 as argument.
Vector<3> test;
Template pointer parameter (passing a pointer to a function)
template<void (*F)()>
struct FunctionWrapper {
static void call_it() { F(); }
};
// pass address of function do_it as argument.
void do_it() { }
FunctionWrapper<&do_it> test;
Template reference parameter (passing an integer)
template<int &A>
struct SillyExample {
static void do_it() { A = 10; }
};
// pass flag as argument
int flag;
SillyExample<flag> test;
Template template parameter.
template<template<typename T> class AllocatePolicy>
struct Pool {
void allocate(size_t n) {
int *p = AllocatePolicy<int>::allocate(n);
}
};
// pass the template "allocator" as argument.
template<typename T>
struct allocator { static T * allocate(size_t n) { return 0; } };
Pool<allocator> test;
A template without any parameters is not possible. But a template without any explicit argument is possible - it has default arguments:
template<unsigned int SIZE = 3>
struct Vector {
unsigned char buffer[SIZE];
};
Vector<> test;
Syntactically, template<>
is reserved to mark an explicit template specialization, instead of a template without parameters:
template<>
struct Vector<3> {
// alternative definition for SIZE == 3
};
Use Vim:
diff /path/to/a /path/to/b | vim -R -
Or better still, VimDiff (or vim -d
, which is shorter to type) will show differences between two, three or four files side-by-side.
vim -d /path/to/[ab]
vimdiff file1 file2 file3 file4
If you are using a global installation of ESLint, any plugins used in your configuration must also be installed globally. Like wise for local install. if u have installed locally and properly configured locally, yet eslint isn't working, try restarting your IDE. This just happened to me with VScode.
Under TARGETS
in your project, right-click on your project target (should be the same name as your project) and choose GET INFO
, then on GENERAL
tab you will see DIRECT DEPENDENCIES
, simply click the [+]
and select SoundCloudAPI
.
Way 1: only works for dataURL, not for other types of url.
function dataURLtoFile(dataurl, filename) {
var arr = dataurl.split(','), mime = arr[0].match(/:(.*?);/)[1],
bstr = atob(arr[1]), n = bstr.length, u8arr = new Uint8Array(n);
while(n--){
u8arr[n] = bstr.charCodeAt(n);
}
return new File([u8arr], filename, {type:mime});
}
//Usage example:
var file = dataURLtoFile('data:image/png;base64,......', 'a.png');
console.log(file);
Way 2: works for any type of url, (http url, dataURL, blobURL, etc...)
//return a promise that resolves with a File instance
function urltoFile(url, filename, mimeType){
mimeType = mimeType || (url.match(/^data:([^;]+);/)||'')[1];
return (fetch(url)
.then(function(res){return res.arrayBuffer();})
.then(function(buf){return new File([buf], filename, {type:mimeType});})
);
}
//Usage example:
urltoFile('data:image/png;base64,......', 'a.png')
.then(function(file){
console.log(file);
})
Both works in Chrome and Firefox.
I have hosted an open-source project to enable Android phone to IP camera:
http://code.google.com/p/ipcamera-for-android
Raw video data is fetched from LocalSocket, and the MDAT MOOV of MP4 was checked first before streaming. The live video is packed in FLV format, and can be played via Flash video player with a build in web server :)
You can also check like struct_var == (struct{})
. This does not allow you to compare to nil but it does check if it is initialized or not. Be careful while using this method. If your struct can have zero values for all of its fields you won't have great time.
package main
import "fmt"
type A struct {
Name string
}
func main() {
a := A{"Hello"}
var b A
if a == (A{}) {
fmt.Println("A is empty") // Does not print
}
if b == (A{}) {
fmt.Println("B is empty") // Prints
}
}
Brave browser on iOS behaves differently (buggy?). It changes viewport height dynamically accordingly to showing/hiding address bar. It is kind of annoying because it changes page's layout dependent on vw/vh units.
Chrome and Safari is fine.
Nope, you can't use CUDA for that. CUDA is limited to NVIDIA hardware. OpenCL would be the best alternative.
Khronos itself has a list of resources. As does the StreamComputing.eu website. For your AMD specific resources, you might want to have a look at AMD's APP SDK page.
Note that at this time there are several initiatives to translate/cross-compile CUDA to different languages and APIs. One such an example is HIP. Note however that this still does not mean that CUDA runs on AMD GPUs.
One other thing to check with your connection string - the model name. I was using two entity models, DB first. In the config I copied the entity connection for one, renamed it, and changed the connection string part. What I didn't change was the model name, so while the entity model generated correctly, when the context was initiated EF was looking in the wrong model for the entities.
Looks obvious written down, but there are four hours I won't get back.
Obviously you can't parse N/A
to int
value. you can do something like following to handle that NumberFormatException
.
String str="N/A";
try {
int val=Integer.parseInt(str);
}catch (NumberFormatException e){
System.out.println("not a number");
}
This will happen if the host page is HTTPS and the included javascript source path is HTTP. The two protocols must be the same, HTTPS. The tell tail sign would be to check under Firebug and notice that the JS is "denied access".
i will provide mine because @muni s solution was a bit overkill for me
note: if you want to add custom definitions for several resolutions together, say something like this:
//mobile generally
@media screen and (max-width: 1199) {
.irns-desktop{
display: none;
}
.irns-mobile{
display: initial;
}
}
Be sure to add those definitions on top of the accurate definitions, so it cascades correctly (e.g. 'smartphone portrait' must win versus 'mobile generally')
//here all definitions to apply globally
//desktop
@media only screen
and (min-width : 1200) {
}
//tablet landscape
@media screen and (min-width: 1024px) and (max-width: 1600px) {
} // end media query
//tablet portrait
@media screen and (min-width: 768px) and (max-width: 1023px) {
}//end media definition
//smartphone landscape
@media screen and (min-width: 480px) and (max-width: 767px) {
}//end media query
//smartphone portrait
@media screen /*and (min-width: 320px)*/
and (max-width: 479px) {
}
//end media query
SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log
method has been changed (added Object[] p5):
SLF4J 1.5.11:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Throwable p5 )
SLF4J 1.6.0:
LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
String p4, Object[] p5, Throwable p6 )
See compatibility reports for other SLF4J versions on this page.
You can generate such reports by the japi-compliance-checker tool.
$ip = $_SERVER['REMOTE_ADDR'];
The path-matching strategy, one of 'prefix' or 'full'. Default is 'prefix'.
By default, the router checks URL elements from the left to see if the URL matches a given path, and stops when there is a match. For example, '/team/11/user' matches 'team/:id'.
The path-match strategy 'full' matches against the entire URL. It is important to do this when redirecting empty-path routes. Otherwise, because an empty path is a prefix of any URL, the router would apply the redirect even when navigating to the redirect destination, creating an endless loop.
I did not find the accepted answer helpful in resolving the exception encountered in my code. And while not technically incorrect, I was also not satisfied with others' suggestions to introduce redundancy:
configuration.addAnnotatedClass(...)
hbm.xml
file and resource mapping in hibernate_test.cfg.xml
that were redundant to the existing annotationsHowever, I found 2 possible solutions that I wanted to share, both of which independently resolved the exception I encountered in my own code.
I was having the same MappingException
as @ron (using a very nearly identical HibernateUtil
class):
public final class HibernateUtil {
private static SessionFactory sessionFactory = null;
private static ServiceRegistry serviceRegistry = null;
private HibernateUtil() {}
public static synchronized SessionFactory getSessionFactory() {
if ( sessionFactory == null ) {
Configuration configuration = new Configuration().configure("hibernate_test.cfg.xml");
serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings(configuration.getProperties())
.build();
sessionFactory = configuration.buildSessionFactory( serviceRegistry );
}
return sessionFactory;
}
// exception handling and closeSessionFactory() omitted for brevity
}
Within my hibernate_test.cfg.xml
configuration file, I have the required class mapping:
<mapping class="myPackage.Device"/>
And my Device
class is properly annotated with the javax.persistence.Entity
annotation:
package myPackage.core;
import javax.persistence.*;
@Entity
@Table( name = "devices" )
public class Device {
//body omitted for brevity
}
Two Possible Solutions:
First, I am using Hibernate 5.2, and for those using Hibernate 5 this solution using a Metadata
object to build a SessionFactory
should work. It also appears to be the currently recommended native bootstrap mechanism in the Hibernate Getting Started Guide :
public static synchronized SessionFactory getSessionFactory() {
if ( sessionFactory == null ) {
// exception handling omitted for brevity
serviceRegistry = new StandardServiceRegistryBuilder()
.configure("hibernate_test.cfg.xml")
.build();
sessionFactory = new MetadataSources( serviceRegistry )
.buildMetadata()
.buildSessionFactory();
}
return sessionFactory;
}
Second, while Configuration
is semi-deprecated in Hibernate 5, @ron didn't say which version of Hibernate he was using, so this solution could also be of value to some.
I found a very subtle change in the order of operations when instantiating and configuring Configuration
and ServiceRegistry
objects to make all the difference in my own code.
Original order (Configuration
created and configured prior to ServiceRegistry
):
public static synchronized SessionFactory getSessionFactory() {
if ( sessionFactory == null ) {
// exception handling omitted for brevity
Configuration configuration = new Configuration().configure("hibernate_test.cfg.xml");
serviceRegistry = new StandardServiceRegistryBuilder()
.applySettings( configuration.getProperties() )
.build();
sessionFactory = configuration.buildSessionFactory( serviceRegistry );
}
return sessionFactory;
}
New order (ServiceRegistry
created and configured prior to Configuration
):
public static synchronized SessionFactory getSessionFactory() {
if ( sessionFactory == null ) {
// exception handling omitted for brevity
serviceRegistry = new StandardServiceRegistryBuilder()
.configure("hibernate_test.cfg.xml")
.build();
sessionFactory = new Configuration().buildSessionFactory( serviceRegistry );
}
return sessionFactory;
}
At the risk of TLDR, I will also point out that with respect to hibernate_test.cfg.xml
my testing suggests that the configuration.getProperties()
method only returns <property />
elements, and <mapping />
elements are excluded. This appears consistent with the specific use of the terms 'property' and 'mapping' within the API documentation for Configuration
. I will concede that this behaviour may have something to do with the failure of applySettings()
to yield the mapping data to the StandardServiceRegistryBuilder
. However, this mapping data should already have been parsed during configuration of the Configuration
object and available to it when buildSessionFactory()
is called. Therefore, I suspect this may be due to implementation-specific details regarding resource precedence when a ServiceRegistry
is passed to a Configuration
object's buildSessionFactory()
method.
I know this question is several years old now, but I hope this answer saves somebody the hours of research I spent in deriving it. Cheers!
Mby bootstrap img-responsive
class is you looking for.
Bind & protected-mode both are the essential steps. But if ufw is enabled then you will have to make redis port allow in ufw.
ufw status
if Status: active
then allow redis-port ufw allow 6379
vi /etc/redis/redis.conf
bind 127.0.0.1
to bind 0.0.0.0
protected-mode yes
to protected-mode no
It worked fine with me,
$this->db->where("your_id !=",$your_id);
Or try this one,
$this->db->where("your_id <>",$your_id);
Or try this one,
$this->db->where("your_id IS NOT NULL");
all will work.
This one works on Bootstrap 4.3.1.

I would think that your first question is simply a matter of scope. The ServletContext is a much more broad scoped object (the whole servlet context) than a ServletRequest, which is simply a single request. You might look to the Servlet specification itself for more detailed information.
As to how, I am sorry but I will have to leave that for others to answer at this time.

Your code should work just as you expect it to if you add @classmethod
decorators.
@classmethod
def setup_class(cls):
"Runs once per class"
@classmethod
def teardown_class(cls):
"Runs at end of class"
See http://pythontesting.net/framework/pytest/pytest-xunit-style-fixtures/
Chain selectors are not limited just to classes, you can do it for both classes and ids.
Classes
.classA.classB {
/*style here*/
}
Class & Id
.classA#idB {
/*style here*/
}
Id & Id
#idA#idB {
/*style here*/
}
All good current browsers support this except IE 6, it selects based on the last selector in the list. So ".classA.classB" will select based on just ".classB".
For your case
li.left.ui-class-selector {
/*style here*/
}
or
.left.ui-class-selector {
/*style here*/
}
os.system
is equivalent to Unix system
command, while subprocess
was a helper module created to provide many of the facilities provided by the Popen
commands with an easier and controllable interface. Those were designed similar to the Unix Popen command.
system()
executes a command specified in command by calling/bin/sh -c command
, and returns after the command has been completed
Whereas:
The
popen()
function opens a process by creating a pipe, forking, and invoking the shell.
If you are thinking which one to use, then use subprocess
definitely because you have all the facilities for execution, plus additional control over the process.
PHP has JSON_PRETTY_PRINT option since 5.4.0 (release date 01-Mar-2012).
This should do the job:
$json = json_decode($string);
echo json_encode($json, JSON_PRETTY_PRINT);
See http://www.php.net/manual/en/function.json-encode.php
Note: Don't forget to echo "<pre>" before and "</pre>" after, if you're printing it in HTML to preserve formatting ;)

The code that has to be executed for both alternatives is so similar that you can’t predict a result reliably. The underlying object structure might differ but that’s no challenge to the hotspot optimizer. So it depends on other surrounding conditions which will yield to a faster execution, if there is any difference.
Combining two filter instances creates more objects and hence more delegating code but this can change if you use method references rather than lambda expressions, e.g. replace filter(x -> x.isCool())
by filter(ItemType::isCool)
. That way you have eliminated the synthetic delegating method created for your lambda expression. So combining two filters using two method references might create the same or lesser delegation code than a single filter
invocation using a lambda expression with &&
.
But, as said, this kind of overhead will be eliminated by the HotSpot optimizer and is negligible.
In theory, two filters could be easier parallelized than a single filter but that’s only relevant for rather computational intense tasks¹.
So there is no simple answer.
The bottom line is, don’t think about such performance differences below the odor detection threshold. Use what is more readable.
¹…and would require an implementation doing parallel processing of subsequent stages, a road currently not taken by the standard Stream implementation
Another addition: be careful when replacing multiples and converting the type of the column back from object to float. If you want to be certain that your None
's won't flip back to np.NaN
's apply @andy-hayden's suggestion with using pd.where
.
Illustration of how replace can still go 'wrong':
In [1]: import pandas as pd
In [2]: import numpy as np
In [3]: df = pd.DataFrame({"a": [1, np.NAN, np.inf]})
In [4]: df
Out[4]:
a
0 1.0
1 NaN
2 inf
In [5]: df.replace({np.NAN: None})
Out[5]:
a
0 1
1 None
2 inf
In [6]: df.replace({np.NAN: None, np.inf: None})
Out[6]:
a
0 1.0
1 NaN
2 NaN
In [7]: df.where((pd.notnull(df)), None).replace({np.inf: None})
Out[7]:
a
0 1.0
1 NaN
2 NaN
To make this simple, you have two options to reapply your stash:
git stash pop
- Restore back to the saved state, but it deletes the stash from the temporary storage.git stash apply
- Restore back to the saved state and leaves the stash list for possible later reuse.You can read in more detail about git stashes in this article.
Here's a quick ruby script that corrals up the impact per user against a given log query.
For example, for rubinius:
Brian Ford: 4410668
Evan Phoenix: 1906343
Ryan Davis: 855674
Shane Becker: 242904
Alexander Kellett: 167600
Eric Hodel: 132986
Dirkjan Bussink: 113756
...
the script:
#!/usr/bin/env ruby
impact = Hash.new(0)
IO.popen("git log --pretty=format:\"%an\" --shortstat #{ARGV.join(' ')}") do |f|
prev_line = ''
while line = f.gets
changes = /(\d+) insertions.*(\d+) deletions/.match(line)
if changes
impact[prev_line] += changes[1].to_i + changes[2].to_i
end
prev_line = line # Names are on a line of their own, just before the stats
end
end
impact.sort_by { |a,i| -i }.each do |author, impact|
puts "#{author.strip}: #{impact}"
end
First, you need to decode it :
$jsonString = file_get_contents('jsonFile.json');
$data = json_decode($jsonString, true);
Then change the data :
$data[0]['activity_name'] = "TENNIS";
// or if you want to change all entries with activity_code "1"
foreach ($data as $key => $entry) {
if ($entry['activity_code'] == '1') {
$data[$key]['activity_name'] = "TENNIS";
}
}
Then re-encode it and save it back in the file:
$newJsonString = json_encode($data);
file_put_contents('jsonFile.json', $newJsonString);
It's in the python docs.
import datetime
datetime.datetime.combine(datetime.date(2011, 1, 1),
datetime.time(10, 23))
returns
datetime.datetime(2011, 1, 1, 10, 23)
If using RCurl you get an SSL error on the GetURL() function then set these options before GetURL(). This will set the CurlSSL settings globally.
The extended code:
install.packages("RCurl")
library(RCurl)
options(RCurlOptions = list(cainfo = system.file("CurlSSL", "cacert.pem", package = "RCurl")))
URL <- "https://d396qusza40orc.cloudfront.net/getdata%2Fdata%2Fss06hid.csv"
x <- getURL(URL)
Worked for me on Windows 7 64-bit using R3.1.0!
You can do this in 2 steps:
1: Change the input type(In your EditText
field) in the layout file to android:inputType="number"
2: Use int a = Integer.parseInt(yourEditTextObject.getText().toString());
Add a div with ID imgDiv and make your script
document.getElementById('imgDiv').innerHTML='<img src=\'http://webpage.com/images/'+document.getElementById('imagename').value +'.png\'>'
I tried to stay as close to your original as tp not overwhelm you with jQuery and such
In case that you have Ubuntu in your machine, the following steps will help you:
Open your terminal and paste: sudo apt-get install php-soap.
Restart your apache2 server in terminal : service apache2 restart.
To check use your php test file again to be seems like mine in step 1.
No JS needed really ...
Just add a type
attribute to the button with a value of button
<Button type="button" color="primary" onClick={this.onTestClick}>primary</Button>
By default, button elements are of the type "submit" which causes them to submit their enclosing form element (if any). Changing the type
to "button" prevents that.
how i solve it in Eclipse
grab the input values after form submission in php
$start_time = $_POST('start_time');
$end_time =$_POST('end_time');
$start = $start_time;
$end = $end_time;
$datetime1 = new DateTime($end);
$datetime2 = new DateTime($start);
//echo $datetime1->format('H:i:s');
$interval = $datetime1->diff($datetime2);
$elapsed = $interval->format('%h:%i');
$time = explode(":",$elapsed);
$hours = $time[0];
$minutes = $time[1];
$tminutes = $minutes + ($hours*60);
the variable $tminutes is total diff in minutes , working hour is $hour . this code is for php use this logic and convert this code to js
The preferred solution as you've described it is a List of Pairs (i.e. List).
To accomplish this you would create a Pair class for use in your collection. This is a useful utility class to add to your code base.
The closest class in the Sun JDK providing functionality similar to a typical Pair class is AbstractMap.SimpleEntry. You could use this class rather than creating your own Pair class, though you would have to live with some awkward restrictions and I think most people would frown on this as not really the intended role of SimpleEntry. For example SimpleEntry has no "setKey()" method and no default constructor, so you may find it too limiting.
Bear in mind that Collections are designed to contain elements of a single type. Related utility interfaces such as Map are not actually Collections (i.e. Map does not implement the Collection interface). A Pair would not implement the Collection interface either but is obviously a useful class in building larger data structures.

My personal experience was that I had installed the Team Foundation Server client for 2017 first (was using it as a Proof of Concept for our QA team, while I was still using VS2015), then followed it up with Installing Visual Studio 2017 later to begin development.
What I ended up with on my Start Menu was a Visual Studio 2017 and a Visual Studio 2017 (2). The Visual Studio 2017 (2) had all the templates I was missing. Following the steps found in the First answer to this question (which were clear and easy to follow) did not fix my issue. I had thought that launching the client would upgrade to the Development Client, but it did not. I renamed it to Visual Studio Professional, and now have everything I need. Not sure if this happens to anyone else, but it was what happened to me, so I hope this helps someone.
Best ways of doing this,
1. WidgetsBinding
WidgetsBinding.instance.addPostFrameCallback((_) {
print("WidgetsBinding");
});
2. SchedulerBinding
SchedulerBinding.instance.addPostFrameCallback((_) {
print("SchedulerBinding");
});
It can be called inside initState
, both will be called only once after Build widgets done with rendering.
@override
void initState() {
// TODO: implement initState
super.initState();
print("initState");
WidgetsBinding.instance.addPostFrameCallback((_) {
print("WidgetsBinding");
});
SchedulerBinding.instance.addPostFrameCallback((_) {
print("SchedulerBinding");
});
}
both above codes will work the same as both use the similar binding framework. For the difference find the below link.

One posibility is to treat the array as a string:
elements = [[180.0, 1, 2, 3], [173.8], [164.2], [156.5], [147.2], [138.2]]
list(map(float, str(elements).replace("[", "").replace("]", "").split(",")))
You can use in swift 4 or 5
let date = Date()
let dateFormatter = DateFormatter()
dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
let current_date_time = dateFormatter.string(from: date)
print("before add time-->",current_date_time)
//adding 5 miniuts
let addminutes = date.addingTimeInterval(5*60)
dateFormatter.dateFormat = "yyyy-MM-dd H:mm:ss"
let after_add_time = dateFormatter.string(from: addminutes)
print("after add time-->",after_add_time)
output:
before add time--> 2020-02-18 10:38:15
after add time--> 2020-02-18 10:43:15
I had similar issue. try this $('#myAnchor').get(0).click();
this works for me
if you want request
import on windows:
pip install request
then beautifulsoup4
for:
pip3 install beautifulsoup4
Git ignores folders if you write:
/js
but it can't add exceptions if you do:
!/js/jquery
or !/js/jquery/
or !/js/jquery/*
You must write:
/js/*
and only then you can except subfolders like this
!/js/jquery
Highlight the cells, format cells, select Custom then select zero.
We can use signals for the same. I think the below example will be useful for you. It is very simple compared to threads.
import signal
def timeout(signum, frame):
raise myException
#this is an infinite loop, never ending under normal circumstances
def main():
print 'Starting Main ',
while 1:
print 'in main ',
#SIGALRM is only usable on a unix platform
signal.signal(signal.SIGALRM, timeout)
#change 5 to however many seconds you need
signal.alarm(5)
try:
main()
except myException:
print "whoops"
If you were going to add a contains
function, it might look like this:
#include <algorithm>
#include <iterator>
template<class TInputIterator, class T> inline
bool contains(TInputIterator first, TInputIterator last, const T& value)
{
return std::find(first, last, value) != last;
}
template<class TContainer, class T> inline
bool contains(const TContainer& container, const T& value)
{
// This works with more containers but requires std::begin and std::end
// from C++0x, which you can get either:
// 1. By using a C++0x compiler or
// 2. Including the utility functions below.
return contains(std::begin(container), std::end(container), value);
// This works pre-C++0x (and without the utility functions below, but doesn't
// work for fixed-length arrays.
//return contains(container.begin(), container.end(), value);
}
template<class T> inline
bool contains(const std::set<T>& container, const T& value)
{
return container.find(value) != container.end();
}
This works with std::set
, other STL containers, and even fixed-length arrays:
void test()
{
std::set<int> set;
set.insert(1);
set.insert(4);
assert(!contains(set, 3));
int set2[] = { 1, 2, 3 };
assert(contains(set2, 3));
}
As pointed out in the comments, I unintentionally used a function new to C++0x (std::begin
and std::end
). Here is the near-trivial implementation from VS2010:
namespace std {
template<class _Container> inline
typename _Container::iterator begin(_Container& _Cont)
{ // get beginning of sequence
return (_Cont.begin());
}
template<class _Container> inline
typename _Container::const_iterator begin(const _Container& _Cont)
{ // get beginning of sequence
return (_Cont.begin());
}
template<class _Container> inline
typename _Container::iterator end(_Container& _Cont)
{ // get end of sequence
return (_Cont.end());
}
template<class _Container> inline
typename _Container::const_iterator end(const _Container& _Cont)
{ // get end of sequence
return (_Cont.end());
}
template<class _Ty,
size_t _Size> inline
_Ty *begin(_Ty (&_Array)[_Size])
{ // get beginning of array
return (&_Array[0]);
}
template<class _Ty,
size_t _Size> inline
_Ty *end(_Ty (&_Array)[_Size])
{ // get end of array
return (&_Array[0] + _Size);
}
}
Here's an elegant array formula (which I found here http://www.excel-easy.com/examples/count-unique-values.html) that does the trick nicely:
Type
=SUM(1/COUNTIF(List,List))
and confirm with CTRL-SHIFT-ENTER
Just something to watch out for......
In SQL Server 2008 R2 SSMS, the "Script Constraint as -> DROP And CREATE To" command produces T-SQL like below
USE [MyDatabase]
GO
IF EXISTS (SELECT * FROM dbo.sysobjects WHERE id = OBJECT_ID(N'[DEF_Detail_IsDeleted]') AND type = 'D')
BEGIN
ALTER TABLE [Patient].[Detail] DROP CONSTRAINT [DEF_Detail_IsDeleted]
END
GO
USE [MyDatabase]
GO
ALTER TABLE [Patient].[Detail] ADD CONSTRAINT [DEF_Detail_IsDeleted] DEFAULT ((0)) FOR [IsDeleted]
GO
Out of the box, this script does NOT drop the constraint because the SELECT returns 0 rows. (see post Microsoft Connect).
The name of the default constraint is wrong but I gather it also has something to do with the OBJECT_ID function because changing the name doesn't fix the problem.
To fix this, I removed the usage of OBJECT_ID and used the default constraint name instead.
(SELECT * FROM dbo.sysobjects WHERE [name] = (N'DEF_Detail_IsDeleted') AND type = 'D')
The Android SDK generates a "debug" signing certificate for you in a keystore called debug.keystore
.The Eclipse plug-in uses this certificate to sign each application build that is generated.
Unfortunately a debug certificate is only valid for 365 days. To generate a new one, you must delete the existing debug.keystore
file. Its location is platform dependent - you can find it in Preferences -> Android -> Build -> *Default debug keystore.
DOS: del c:\user\dad.android\debug.keystore
Eclipse: In Project, Clean the project. Close Eclipse. Re-open Eclipse.
Eclipse: Start the Emulator. Remove the Application from the emulator.
Manually delete debug.keystore
from the .android
folder.
You can find the .android
folder like this: home/username/.android
Note: the default .android
file will be hidden.
So click on the places menu. Under select home folder. Under click on view, under click show hidden files and then the .android
folder will be visible.
Delete debug.keystore
from the .android folder
.
Then clean your project. Now Android will generate a new .android folder
file.
According to the documentation since Symfony 2.1 simply use this shortcut :
$user = $this->getUser();
The above is still working on Symfony 3.2 and is a shortcut for this :
$user = $this->get('security.token_storage')->getToken()->getUser();
The
security.token_storage
service was introduced in Symfony 2.6. Prior to Symfony 2.6, you had to use thegetToken()
method of thesecurity.context
service.
Example : And if you want directly the username :
$username = $this->getUser()->getUsername();
The user will be an object and the class of that object will depend on your user provider.
Thanks all for your responses. I used HtmlRenderer external dll (library) to achieve the same and found below code for the same.
Here is the code for this
public void ConvertHtmlToImage()
{
Bitmap m_Bitmap = new Bitmap(400, 600);
PointF point = new PointF(0, 0);
SizeF maxSize = new System.Drawing.SizeF(500, 500);
HtmlRenderer.HtmlRender.Render(Graphics.FromImage(m_Bitmap),
"<html><body><p>This is some html code</p>"
+ "<p>This is another html line</p></body>",
point, maxSize);
m_Bitmap.Save(@"C:\Test.png", ImageFormat.Png);
}
To put breakpoints in your code, double click in the left margin on the line you want execution to stop on. You may alternatively put your cursor in this line and then press Shift+Ctrl+B.
To control execution use the Step Into, Step Over and Step Return buttons. They have the shortcuts F5, F6 and F7 respectively.
To allow execution to continue normally or until it hits the next breakpoint, hit the Resume button or F8.
The "a:hover
" literally tells the browser to change the properties for the <a>
-tag, when the mouse is hovered over it. What you perhaps meant was "the div:hover
" instead, which would trigger when the div was chosen.
Just to make sure, if you want to change only one particular div, give it an id ("<div id='something'>
") and use the CSS "#something:hover {...}
" instead. If you want to edit a group of divs, make them into a class ("<div class='else'>
") and use the CSS ".else {...}
" in this case (note the period before the class' name!)
This is a later answer that works for me, if it may be of use to anyone in the future. I wanted a simple border around all four sides of the grid and I achieved it like so...
<DataGrid x:Name="dgDisplay" Margin="5" BorderBrush="#1266a7" BorderThickness="1"...
This usually happens because the environment has changed since running npm install
.
Running npm rebuild node-sass
builds the binding for the current environment.
You need to add style="overflow-y:scroll;"
to the div tag. (This will force a scrollbar on the vertical).
If you only want a scrollbar when needed, just do overflow-y:auto;
With no argument:
ourObject = PowerMockito.spy(new OurClass());
when(ourObject , "ourPrivateMethodName").thenReturn("mocked result");
With String
argument:
ourObject = PowerMockito.spy(new OurClass());
when(ourObject, method(OurClass.class, "ourPrivateMethodName", String.class))
.withArguments(anyString()).thenReturn("mocked result");
Not tested, but probably something like if(preg_match("/^[0-9,]+$/", $a)) $a = str_replace(...)
Do it the other way around:
$a = "1,435";
$b = str_replace( ',', '', $a );
if( is_numeric( $b ) ) {
$a = $b;
}
The easiest would be:
$var = intval(preg_replace('/[^\d.]/', '', $var));
or if you need float:
$var = floatval(preg_replace('/[^\d.]/', '', $var));
My solution using Java 8 lambdas:
public static <T extends Throwable> T assertThrows(Class<T> expected, ThrowingRunnable action) throws Throwable {
try {
action.run();
Assert.fail("Did not throw expected " + expected.getSimpleName());
return null; // never actually
} catch (Throwable actual) {
if (!expected.isAssignableFrom(actual.getClass())) { // runtime '!(actual instanceof expected)'
System.err.println("Threw " + actual.getClass().getSimpleName()
+ ", which is not a subtype of expected "
+ expected.getSimpleName());
throw actual; // throw the unexpected Throwable for maximum transparency
} else {
return (T) actual; // return the expected Throwable for further examination
}
}
}
You have to define a FunctionalInterface, because Runnable
doesn't declare the required throws
.
@FunctionalInterface
public interface ThrowingRunnable {
void run() throws Throwable;
}
The method can be used as follows:
class CustomException extends Exception {
public final String message;
public CustomException(final String message) { this.message = message;}
}
CustomException e = assertThrows(CustomException.class, () -> {
throw new CustomException("Lorem Ipsum");
});
assertEquals("Lorem Ipsum", e.message);
You can write a script and then use nohup ./yourscript &
to execute
For example:
vi yourscript
put
#!/bin/bash
script here
you may also need to change permission to run script on server
chmod u+rwx yourscript
finally
nohup ./yourscript &
After playing around, really all you have to do is change two lines in the httpd.conf file:
Change "Listen 80" to "Listen 122" (or anything else you want)
and
"ServerName Localhost:80" to "Localhost:122" (or the port you changed above)
Then it all should fire right up :P
django.setup() in the top will not work while you are running a script explicitly. My problem solved when I added this in the bottom of the settings file
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
import sys
if BASE_DIR not in sys.path:
sys.path.append(BASE_DIR)
os.environ['DJANGO_SETTINGS_MODULE'] = "igp_lrpe.settings"
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "igp_lrpe.settings")
import django
django.setup()
AGE
is defined as "42"
so the line:
str += "Do you feel " + AGE + " years old?";
is converted to:
str += "Do you feel " + "42" + " years old?";
Which isn't valid since "Do you feel "
and "42"
are both const char[]
. To solve this, you can make one a std::string
, or just remove the +
:
// 1.
str += std::string("Do you feel ") + AGE + " years old?";
// 2.
str += "Do you feel " AGE " years old?";
You can achieve this by using simply as a returns set of records using return query.
CREATE OR REPLACE FUNCTION schemaName.get_two_users_from_school(schoolid bigint)
RETURNS SETOF record
LANGUAGE plpgsql
AS $function$
begin
return query
SELECT id, name FROM schemaName.user where school_id = schoolid;
end;
$function$
And call this function as : select * from schemaName.get_two_users_from_school(schoolid) as x(a bigint, b varchar);
String s=null;
String is not initialized for null. if any string operation tried it can throw null pointer exception
String t="null";
It is a string literal with value string "null" same like t = "xyz". It will not throw null pointer.
String u="";
It is as empty string , It will not throw null pointer.
The error indicates another process is trying to access the file. Maybe you or someone else has it open while you are attempting to write to it. "Read" or "Copy" usually doesn't cause this, but writing to it or calling delete on it would.
There are some basic things to avoid this, as other answers have mentioned:
In FileStream
operations, place it in a using
block with a FileShare.ReadWrite
mode of access.
For example:
using (FileStream stream = File.Open(path, FileMode.Open, FileAccess.Write, FileShare.ReadWrite))
{
}
Note that FileAccess.ReadWrite
is not possible if you use FileMode.Append
.
I ran across this issue when I was using an input stream to do a File.SaveAs
when the file was in use. In my case I found, I didn't actually need to save it back to the file system at all, so I ended up just removing that, but I probably could've tried creating a FileStream in a using
statement with FileAccess.ReadWrite
, much like the code above.
Saving your data as a different file and going back to delete the old one when it is found to be no longer in use, then renaming the one that saved successfully to the name of the original one is an option. How you test for the file being in use is accomplished through the
List<Process> lstProcs = ProcessHandler.WhoIsLocking(file);
line in my code below, and could be done in a Windows service, on a loop, if you have a particular file you want to watch and delete regularly when you want to replace it. If you don't always have the same file, a text file or database table could be updated that the service always checks for file names, and then performs that check for processes & subsequently performs the process kills and deletion on it, as I describe in the next option. Note that you'll need an account user name and password that has Admin privileges on the given computer, of course, to perform the deletion and ending of processes.
When you don't know if a file will be in use when you are trying to save it, you can close all processes that could be using it, like Word, if it's a Word document, ahead of the save.
If it is local, you can do this:
ProcessHandler.localProcessKill("winword.exe");
If it is remote, you can do this:
ProcessHandler.remoteProcessKill(computerName, txtUserName, txtPassword, "winword.exe");
where txtUserName
is in the form of DOMAIN\user
.
Let's say you don't know the process name that is locking the file. Then, you can do this:
List<Process> lstProcs = new List<Process>();
lstProcs = ProcessHandler.WhoIsLocking(file);
foreach (Process p in lstProcs)
{
if (p.MachineName == ".")
ProcessHandler.localProcessKill(p.ProcessName);
else
ProcessHandler.remoteProcessKill(p.MachineName, txtUserName, txtPassword, p.ProcessName);
}
Note that file
must be the UNC path: \\computer\share\yourdoc.docx
in order for the Process
to figure out what computer it's on and p.MachineName
to be valid.

It looks like the JavaScript error your getting is probably being caused by
password: {
required:true,
rangelenght:[4.20]
},
As the [4.20]
should be [4,20]
, which i'd guess is throwing off the validation code in additional-methods
hence giving the type error's you posted.
Edit: As others have noted in the below comments rangelenght
is also misspelled & jquery.validate.js
library appears to be missing (assuming its not compiled in to one of your other assets)
This workaround also works with 15.04 (64bit). Since there isn't (yet?) lib32bz2-1.0 for vivid:
http://packages.ubuntu.com/search?keywords=lib32bz2-1.0
I installed the one from Utopic.
Here's a generalizable base R function:
pad_left <- function(x, len = 1 + max(nchar(x)), char = '0'){
unlist(lapply(x, function(x) {
paste0(
paste(rep(char, len - nchar(x)), collapse = ''),
x
)
}))
}
pad_left(1:100)
I like sprintf
but it comes with caveats like:
however the actual implementation will follow the C99 standard and fine details (especially the behaviour under user error) may depend on the platform
Give an ID to your span and then change the text of target span.
$("#StatusTitle").text("Info");
$("#StatusTitleIcon").removeClass("fa-exclamation").addClass("fa-info-circle");
<i id="StatusTitleIcon" class="fa fa-exclamation fa-fw"></i>
<span id="StatusTitle">Error</span>
Here "Error" text will become "Info" and their fontawesome icons will be changed as well.
Try this, it also handles the single quote which is failed to parse by JSON.parse() method and also supports the UTF-8 character code.
parseJSON = function() {
var data = {};
var reader = new FileReader();
reader.onload = function() {
try {
data = JSON.parse(reader.result.replace(/'/g, "\""));
} catch (ex) {
console.log('error' + ex);
}
};
reader.readAsText(fileSelector_test[0].files[0], 'utf-8');

In Eclipse, go to Window → Preferences → General → Network Connections. In the Active Provider combo box, choose "Manual". In the proxy entries table, for each entry click "Edit..." and supply your proxy host, port, username and password details.
import os
path = chap_name
if not os.path.exists(path):
os.makedirs(path)
filename = img_alt + '.jpg'
with open(os.path.join(path, filename), 'wb') as temp_file:
temp_file.write(buff)
Key point is to use os.makedirs
in place of os.mkdir
. It is recursive, i.e. it generates all intermediate directories. See http://docs.python.org/library/os.html
Open the file in binary mode as you are storing binary (jpeg) data.
In response to Edit 2, if img_alt sometimes has '/' in it:
img_alt = os.path.basename(img_alt)
The other answers posted here will work, but the clearest and most efficient function to use is numpy.any()
:
>>> all_zeros = not np.any(a)
or
>>> all_zeros = not a.any()
numpy.all(a==0)
because it uses less RAM. (It does not require the temporary array created by the a==0
term.)numpy.count_nonzero(a)
because it can return immediately when the first nonzero element has been found.np.any()
no longer uses "short-circuit" logic, so you won't see a speed benefit for small arrays.I don't think you can save it without it appearing, but just for saving in multiple formats use the print command. See the answer posted here: Save an imagesc output in Matlab
EL expression:

There are several implicit objects in JSP EL. See Expression Language under the "Implicit Objects" heading.
There are 8 bits in a byte (normally speaking in Windows).
However, if you are dealing with characters, it will depend on the charset/encoding. Unicode character can be 2 or 4 bytes, so that would be 16 or 32 bits, whereas Windows-1252 sometimes incorrectly called ANSI is only 1 bytes so 8 bits.
In Asian version of Windows and some others, the entire system runs in double-byte, so a character is 16 bits.
EDITED
Per Matteo's comment, all contemporary versions of Windows use 16-bits internally per character.
It is hard to get all registry values for VC 2012 so I have written a small function which will go through all dependencies and match on specified version.

{
using (RegistryKey subDir = Registry.LocalMachine.OpenSubKey(dependenciesPath + "\\" + subKeyName))
{
var value = subDir.GetValue("DisplayName")?.ToString() ?? null;
if (string.IsNullOrEmpty(value)) continue;
if (Regex.IsMatch(value, @"C\+\+ 2012")) //here u can specify your version.
{
return true;
}
}
}
}
return false;
}

*data interprets arguments as tuples, instead you have to pass **data which interprets the arguments as dictionary.
data = {'school':'DAV', 'class': '7', 'name': 'abc', 'city': 'pune'}
def my_function(**data):
schoolname = data['school']
cityname = data['city']
standard = data['class']
studentname = data['name']
You can call the function like this:
my_function(**data)
Let's say you have a collection named $services
that you are passing to the view.
If you need a JS array with the names, you can iterate over this as follows:
<script>
const myServices = [];
@foreach ($services as $service)
myServices.push('{{ $service->name }}');
@endforeach
</script>
Note: If the string has special characters (like ó
or HTML code), you can use {!! $service->name !!}
.
If you need an array of objects (with all of the attributes), you can use:
<script>
const myServices = @json($services);
// ...
</script>
Note: This blade directive @json
is not available for old Laravel versions. You can achieve the same result using json_encode
as described in other answers.
Sometimes you don't need to pass a complete collection to the view, and just an array with 1 attribute. If that's your case, you better use $services = Service::pluck('name');
in your Controller.
The email in the profile can be obtained using extended permission but I Guess it's not possible to get the email used to login fb. In my app i wanted to display mulitple fb accounts of a user in a list, i wanted to show the login emails of fb accounts as a unique identifier of the respective accounts but i couldn't get it off from fb, all i got was the primary email in the user profile but in my case my login email and my primary email are different.
I use Portable winpython in Windows, it includes IPython QT console, I could achieve the following.

your console interpreter should support unicode in order to show unicode characters.
Do this:
if (denominator == 0) throw new ArithmeticException("denominator == 0");
ArithmeticException is the exception which is normally thrown when you divide by 0.
FETCH_HEAD
is a short-lived ref, to keep track of what has just been fetched from the remote repository. git pull
first invokes git fetch
, in normal cases fetching a branch from the remote; FETCH_HEAD
points to the tip of this branch (it stores the SHA1 of the commit, just as branches do). git pull
then invokes git merge
, merging FETCH_HEAD
into the current branch.
The result is exactly what you'd expect: the commit at the tip of the appropriate remote branch is merged into the commit at the tip of your current branch.
This is a bit like doing git fetch
without arguments (or git remote update
), updating all your remote branches, then running git merge origin/<branch>
, but using FETCH_HEAD
internally instead to refer to whatever single ref was fetched, instead of needing to name things.
You can try using the standard W3C way:
.transition { transition: all 0.2s, top 0s, left 0s, width 0s, height 0s; }
No, You cannot do that. Use the following line of code instead:
IEnumerable<int> usersIds = new List<int>() {1, 2, 3}.AsEnumerable();
I hope it helps.
This question has already been answered with very smart ways to fulfil the requirement but I am wondering why not take a step back and ask the basic question of why do we need a class with two constructors? If my class needs two constructors then probably the way I am designing my classes needs little more consideration to come up with a design that is cleaner and more testable.
We are trying to mix up how to instantiate a class with the actual class logic.
If a Student object is in a valid state, then does it matter if it was constructed from the row of a DB or data from a web form or a cli request?
Now to answer the question that that may arise here that if we don't add the logic of creating an object from db row, then how do we create an object from the db data, we can simply add another class, call it StudentMapper if you are comfortable with data mapper pattern, in some cases you can use StudentRepository, and if nothing fits your needs you can make a StudentFactory to handle all kinds of object construction tasks.
Bottomline is to keep persistence layer out of our head when we are working on the domain objects.
Try below piece of code.
this.dataGridView1.RefreshEdit();
To extend the given answer with few useful tricks:
var markers = //some array;
var bounds = new google.maps.LatLngBounds();
for(i=0;i<markers.length;i++) {
bounds.extend(markers[i].getPosition());
}
//center the map to a specific spot (city)
map.setCenter(center);
//center the map to the geometric center of all markers
map.setCenter(bounds.getCenter());
map.fitBounds(bounds);
//remove one zoom level to ensure no marker is on the edge.
map.setZoom(map.getZoom()-1);
// set a minimum zoom
// if you got only 1 marker or all markers are on the same address map will be zoomed too much.
if(map.getZoom()> 15){
map.setZoom(15);
}
//Alternatively this code can be used to set the zoom for just 1 marker and to skip redrawing.
//Note that this will not cover the case if you have 2 markers on the same address.
if(count(markers) == 1){
map.setMaxZoom(15);
map.fitBounds(bounds);
map.setMaxZoom(Null)
}
UPDATE:
Further research in the topic show that fitBounds() is a asynchronic
and it is best to make Zoom manipulation with a listener defined before calling Fit Bounds.
Thanks @Tim, @xr280xr, more examples on the topic : SO:setzoom-after-fitbounds
google.maps.event.addListenerOnce(map, 'bounds_changed', function(event) {
this.setZoom(map.getZoom()-1);
if (this.getZoom() > 15) {
this.setZoom(15);
}
});
map.fitBounds(bounds);
You could use CSS to do that, but it wouldn't be supported in IE8-. You can use some site like http://borderradius.com to come up with actual CSS you'd use, which would look something like this (again, depending on how many browsers you're trying to support):
-webkit-border-radius: 5px;
-moz-border-radius: 5px;
border-radius: 5px;
Personally I like the & function for this
Assuming that you are using cells A1 and A2 for John Smith
=left(a1,1) & b1
If you want to add text between, for example a period
=left(a1,1) & "." & b1
method = POST
will work if you 'post' a form to the url /test.
if you type a url in address bar of a browser and hit enter, it's always a GET
request, so you had to specify POST request.
Google for HTTP GET
and HTTP POST
(there are several others like PUT DELETE). They all have their own meaning.
