python setup.py install
You may need administrator privileges for step 5. What you do here thus depends on your operating system. For example in Ubuntu you would say sudo python setup.py install
EDIT- thanks to kwatford (see first comment)
To bypass the need for administrator privileges during step 5 above you may be able to make use of the --user flag. In this way you can install the package only for the current user.
The docs say:
Files will be installed into subdirectories of site.USER_BASE (written as userbase hereafter). This scheme installs pure Python modules and extension modules in the same location (also known as site.USER_SITE). Here are the values for UNIX, including Mac OS X:

A bit late but ... I found a link that I saved a couple of years ago and I thought it might be useful for you guys:
CDE: Automatically create portable Linux applications
http://www.pgbovine.net/cde.html
Execute the binary passing as a argument the name of the binary you want make portable, for example: nmap
./cde_2011-08-15_64bit nmap
The program will read all of libs linked to nmap and its dependencias and it will save all of them in a folder called cde-package/ (in the same directory that you are).
Remember, to launch the portable program you have to exec the binary located in cde-package/nmap.cde

You need to either put your code at the end of the page or wrap it in a document ready call, otherwise you're trying to execute code on elements that don't yet exist. Also, you can reduce your code to:
$('#purpose').on('change', function () {
$("#business").css('display', (this.value == '1') ? 'block' : 'none');
});
If you really need to send the full path of the uploded file, then you'd probably have to use something like a signed java applet as there isn't any way to get this information if the browser doesn't send it.
public class A
{
public int i = 0;
internal virtual void test()
{
Console.WriteLine("A test");
}
}
public class B : A
{
public new int i = 1;
public new void test()
{
Console.WriteLine("B test");
}
}
public class C : B
{
public new int i = 2;
public new void test()
{
Console.WriteLine("C test - ");
(this as A).test();
}
}
SET IDENTITY_INSERT tableA ON
You have to make a column list for your INSERT statement:
INSERT Into tableA ([id], [c2], [c3], [c4], [c5] )
SELECT [id], [c2], [c3], [c4], [c5] FROM tableB
not like "INSERT Into tableA SELECT ........"
SET IDENTITY_INSERT tableA OFF
Note that both pcolor and "surf + view(2)" do not show the last row and the last column of your 2D data.
On the other hand, using imagesc, you have to be careful with the axes. The surf and the imagesc examples in gevang's answer only (almost -- apart from the last row and column) correspond to each other because the 2D sinc function is symmetric.
To illustrate these 2 points, I produced the figure below with the following code:
[x, y] = meshgrid(1:10,1:5);
z = x.^3 + y.^3;
subplot(3,1,1)
imagesc(flipud(z)), axis equal tight, colorbar
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc')
subplot(3,1,2)
surf(x,y,z,'EdgeColor','None'), view(2), axis equal tight, colorbar
title('surf with view(2)')
subplot(3,1,3)
imagesc(flipud(z)), axis equal tight, colorbar
axis([0.5 9.5 1.5 5.5])
set(gca, 'YTick', 1:5, 'YTickLabel', 5:-1:1);
title('imagesc cropped')
colormap jet
As you can see the 10th row and 5th column are missing in the surf plot. (You can also see this in images in the other answers.)
Note how you can use the "set(gca, 'YTick'..." (and Xtick) command to set the x and y tick labels properly if x and y are not 1:1:N.
Also note that imagesc only makes sense if your z data correspond to xs and ys are (each) equally spaced. If not you can use surf (and possibly duplicate the last column and row and one more "(end,end)" value -- although that's a kind of a dirty approach).
The params object is included in $stateParams, but won't be part of the url.
1) In the route configuration:
$stateProvider.state('edit_user', {
url: '/users/:user_id/edit',
templateUrl: 'views/editUser.html',
controller: 'editUserCtrl',
params: {
paramOne: { objectProperty: "defaultValueOne" }, //default value
paramTwo: "defaultValueTwo"
}
});
2) In the controller:
.controller('editUserCtrl', function ($stateParams, $scope) {
$scope.paramOne = $stateParams.paramOne;
$scope.paramTwo = $stateParams.paramTwo;
});
3A) Changing the State from a controller
$state.go("edit_user", {
user_id: 1,
paramOne: { objectProperty: "test_not_default1" },
paramTwo: "from controller"
});
3B) Changing the State in html
<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>
The easiest solution is to toggleClass()
both classes individually.
Let's say you have an icon:
<i id="target" class="fa fa-angle-down"></i>
To toggle between fa-angle-down
and fa-angle-up
do the following:
$('.sometrigger').click(function(){
$('#target').toggleClass('fa-angle-down');
$('#target').toggleClass('fa-angle-up');
});
Since we had fa-angle-down
at the beginning without fa-angle-up
each time you toggle both, one leaves for the other to appear.
Here is a working example from your jsbin:
HTML:
<!DOCTYPE html>
<html>
<head>
<script src="//fb.me/react-with-addons-0.9.0.js"></script>
<meta charset=utf-8 />
<title>JS Bin</title>
</head>
<body>
<div id="main-content"></div>
</body>
</html>
jsx:
<script type="text/jsx">
/** @jsx React.DOM */
var LikeOrNot = React.createClass({
render: function () {
return (
<p>Like</p>
);
}
});
React.renderComponent(<LikeOrNot />, document.getElementById('main-content'));
</script>
Run this code from a single file and your it should work.
Assuming the column is set to support NULL as a value:
UPDATE YOUR_TABLE
SET column = NULL
Be aware of the database NULL handling - by default in SQL Server, NULL is an INT. So if the column is a different data type you need to CAST/CONVERT NULL to the proper data type:
UPDATE YOUR_TABLE
SET column = CAST(NULL AS DATETIME)
...assuming column
is a DATETIME data type in the example above.

Yes, but it depends on what you mean by 'embed'; as far as I can tell after reading through the docs, it seems like you have a couple of options if you want to get around using the iframe API. You can use the javascript and flash API's (https://developers.google.com/youtube/player_parameters) to embed a player, but that involves creating Flash objects in your code (something I personally avoid, but not necessarily something that you have to). Below are some helpful sections from the dev docs for the Youtube API.
If you really want to get around all these methods and include video without any sort of iframe, then your best bet might be creating an HTML5 video player/app that can connect to the Youtube Data API (https://developers.google.com/youtube/v3/). I'm not sure what the extent of your needs are, but this would be the way to go if you really want to get around using any iframes or flash objects.
Hope this helps!

(https://developers.google.com/youtube/player_parameters)
IFrame embeds using the IFrame Player API
Follow the IFrame Player API instructions to insert a video player in your web page or application after the Player API's JavaScript code has loaded. The second parameter in the constructor for the video player is an object that specifies player options. Within that object, the playerVars property identifies player parameters.
The HTML and JavaScript code below shows a simple example that inserts a YouTube player into the page element that has an id value of ytplayer. The onYouTubePlayerAPIReady() function specified here is called automatically when the IFrame Player API code has loaded. This code does not define any player parameters and also does not define other event handlers.
...
IFrame embeds using tags
Define an tag in your application in which the src URL specifies the content that the player will load as well as any other player parameters you want to set. The tag's height and width parameters specify the dimensions of the player.
If you are creating the element yourself (rather than using the IFrame Player API to create it), you can append player parameters directly to the end of the URL. The URL has the following format:
...
AS3 object embeds
Object embeds use an tag to specify the player's dimensions and parameters. The sample code below demonstrates how to use an object embed to load an AS3 player that automatically plays the same video as the previous two examples.
In v2.0 of the Graph API, calling /me/friends
returns the person's friends who also use the app.
In addition, in v2.0, you must request the user_friends
permission from each user. user_friends
is no longer included by default in every login. Each user must grant the user_friends
permission in order to appear in the response to /me/friends
. See the Facebook upgrade guide for more detailed information, or review the summary below.
The /me/friendlists
endpoint and user_friendlists
permission are not what you're after. This endpoint does not return the users friends - its lets you access the lists a person has made to organize their friends. It does not return the friends in each of these lists. This API and permission is useful to allow you to render a custom privacy selector when giving people the opportunity to publish back to Facebook.
If you want to access a list of non-app-using friends, there are two options:
If you want to let your people tag their friends in stories that they publish to Facebook using your App, you can use the /me/taggable_friends
API. Use of this endpoint requires review by Facebook and should only be used for the case where you're rendering a list of friends in order to let the user tag them in a post.
If your App is a Game AND your Game supports Facebook Canvas, you can use the /me/invitable_friends
endpoint in order to render a custom invite dialog, then pass the tokens returned by this API to the standard Requests Dialog.
In other cases, apps are no longer able to retrieve the full list of a user's friends (only those friends who have specifically authorized your app using the user_friends
permission).
For apps wanting allow people to invite friends to use an app, you can still use the Send Dialog on Web or the new Message Dialog on iOS and Android.

Let's consider I want specific implementation depending on some dynamic state.
@Bean

case 2:
return new Impl2();
case 3:
return new Impl3();

To resolve this issue, I had to do the following:
Once the DLLs are installed, you can add references to them using the method that Agent007 indicated in his answer.
From the reference docs of Comparable.compareTo(T):
Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
The implementor must ensure sgn(x.compareTo(y)) == -sgn(y.compareTo(x)) for all x and y. (This implies that x.compareTo(y) must throw an exception iff y.compareTo(x) throws an exception.)
The implementor must also ensure that the relation is transitive: (x.compareTo(y)>0 && y.compareTo(z)>0) implies x.compareTo(z)>0.
Finally, the implementor must ensure that x.compareTo(y)==0 implies that sgn(x.compareTo(z)) == sgn(y.compareTo(z)), for all z.
It is strongly recommended, but not strictly required that (x.compareTo(y)==0) == (x.equals(y)). Generally speaking, any class that implements the Comparable interface and violates this condition should clearly indicate this fact. The recommended language is "Note: this class has a natural ordering that is inconsistent with equals."
In the foregoing description, the notation sgn(expression) designates the mathematical signum function, which is defined to return one of -1, 0, or 1 according to whether the value of expression is negative, zero or positive.
In short:
this.compareTo(that)
returns
where the implementation of this method determines the actual semantics of <
>
and ==
(I don't mean ==
in the sense of java's object identity operator)
"abc".compareTo("def")
will yield something smaller than 0 as abc
is alphabetically before def
.
Integer.valueOf(2).compareTo(Integer.valueOf(1))
will yield something larger than 0 because 2 is larger than 1.
Note: It is good practice for a class that implements Comparable to declare the semantics of it's compareTo() method in the javadocs.
Note: you should read at least one of the following:
Warning: you should never rely on the return values of compareTo being -1
, 0
and 1
. You should always test for x < 0
, x == 0
, x > 0
, respectively.
you can use Dependency Walker to view the function name. you can see the function's parameters only if it's decorated. read the following from the FAQ:
How do I view the parameter and return types of a function? For most functions, this information is simply not present in the module. The Windows' module file format only provides a single text string to identify each function. There is no structured way to list the number of parameters, the parameter types, or the return type. However, some languages do something called function "decoration" or "mangling", which is the process of encoding information into the text string. For example, a function like int Foo(int, int) encoded with simple decoration might be exported as _Foo@8. The 8 refers to the number of bytes used by the parameters. If C++ decoration is used, the function would be exported as ?Foo@@YGHHH@Z, which can be directly decoded back to the function's original prototype: int Foo(int, int). Dependency Walker supports C++ undecoration by using the Undecorate C++ Functions Command.
Here's a solution I used (it needs #include <time.h>
):
int msec = 0, trigger = 10; /* 10ms */
clock_t before = clock();
do {
/*
* Do something to busy the CPU just here while you drink a coffee
* Be sure this code will not take more than `trigger` ms
*/
clock_t difference = clock() - before;
msec = difference * 1000 / CLOCKS_PER_SEC;
iterations++;
} while ( msec < trigger );
printf("Time taken %d seconds %d milliseconds (%d iterations)\n",
msec/1000, msec%1000, iterations);
Using pyautogui
To install
pip install pyautogui
and to find the location of the mouse pointer
import pyautogui
print(pyautogui.position())
This will give the pixel location to which mouse pointer is at.
OK, after making a lot of test, here my concluson:
When you perform:
window.open('www.yourdomain.tld','_blank');
window.open('www.yourdomain.tld','myWindow');
or whatever you put in the destination field, this will change nothing: the new page will be opened in a new tab (so depend on user preference)
If you want the page to be opened in a new "real" window, you must put extra parameter. Like:
window.open('www.yourdomain.tld', 'mywindow','location=1,status=1,scrollbars=1, resizable=1, directories=1, toolbar=1, titlebar=1');
After testing, it seems the extra parameter you use, dont' really matter: this is not the fact you put "this parameter" or "this other one" which create the new "real window" but the fact there is new parameter(s).
But something is confused and may explain a lot of wrong answers:
This:
win1 = window.open('myurl1', 'ID_WIN');
win2 = window.open('myurl2', 'ID_WIN', 'location=1,status=1,scrollbars=1');
And this:
win2 = window.open('myurl2', 'ID_WIN', 'location=1,status=1,scrollbars=1');
win1 = window.open('myurl1', 'ID_WIN');
will NOT give the same result.
In the first case, as you first open a page without extra parameter, it will open in a new tab. And in this case, the second call will be also opened in this tab because of the name you give.
In second case, as your first call is made with extra parameter, the page will be opened in a new "real window". And in that case, even if the second call is made without the extra parameter, it will also be opened in this new "real window"... but same tab!
This mean the first call is important as it decided where to put the page.
it is because of using web address, You can not use http to write data. don't use : http:// or https:// in your location for upload files or save data or somting like that. instead of of using $_SERVER["HTTP_REFERER"] use $_SERVER["DOCUMENT_ROOT"]. for example :
wrong :
move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["HTTP_REFERER"].'/uploads/images/1.jpg')
correct:
move_uploaded_file($_FILES["File"]["tmp_name"],$_SERVER["DOCUMENT_ROOT"].'/uploads/images/1.jpg')
Did you remember to die() after sending the header? The 404 header doesn't automatically stop processing, so it may appear not to have done anything if there is further processing happening.
It's not good to REDIRECT to your 404 page, but you can INCLUDE the content from it with no problem. That way, you have a page that properly sends a 404 status from the correct URL, but it also has your "what are you looking for?" page for the human reader.
In short:
If you are using ES6 without transpilers:
class CustomError extends Error { /* ... */}
See Extending Error in Javascript with ES6 syntax for what's the current best practice
If you are using Babel transpiler:
Option 1: use babel-plugin-transform-builtin-extend
Option 2: do it yourself (inspired from that same library)
function CustomError(...args) {
const instance = Reflect.construct(Error, args);
Reflect.setPrototypeOf(instance, Reflect.getPrototypeOf(this));
return instance;
}
CustomError.prototype = Object.create(Error.prototype, {
constructor: {
value: Error,
enumerable: false,
writable: true,
configurable: true
}
});
Reflect.setPrototypeOf(CustomError, Error);
If you are using pure ES5:
function CustomError(message, fileName, lineNumber) {
const instance = new Error(message, fileName, lineNumber);
Object.setPrototypeOf(instance, Object.getPrototypeOf(this));
return instance;
}
CustomError.prototype = Object.create(Error.prototype, {
constructor: {
value: Error,
enumerable: false,
writable: true,
configurable: true
}
});
if (Object.setPrototypeOf){
Object.setPrototypeOf(CustomError, Error);
} else {
CustomError.__proto__ = Error;
}
Alternative: use Classtrophobic framework
Explanation:
Why extending the Error class using ES6 and Babel is a problem?
Because an instance of CustomError is not anymore recognized as such.
class CustomError extends Error {}
console.log(new CustomError('test') instanceof Error);// true
console.log(new CustomError('test') instanceof CustomError);// false
In fact, from the official documentation of Babel, you cannot extend any built-in JavaScript classes such as Date
, Array
, DOM
or Error
.
The issue is described here:
What about the other SO answers?
All the given answers fix the instanceof
issue but you lose the regular error console.log
:
console.log(new CustomError('test'));
// output:
// CustomError {name: "MyError", message: "test", stack: "Error? at CustomError (<anonymous>:4:19)? at <anonymous>:1:5"}
Whereas using the method mentioned above, not only you fix the instanceof
issue but you also keep the regular error console.log
:
console.log(new CustomError('test'));
// output:
// Error: test
// at CustomError (<anonymous>:2:32)
// at <anonymous>:1:5

(Neither IN
nor ANY
is an "operator". A "construct" or "syntax element".)
Logically, quoting the manual:
IN
is equivalent to= ANY
.
But there are two syntax variants of IN
and two variants of ANY
. Details:
IN
taking a set is equivalent to = ANY
taking a set, as demonstrated here:
But the second variant of each is not equivalent to the other. The second variant of the ANY
construct takes an array (must be an actual array type), while the second variant of IN
takes a comma-separated list of values. This leads to different restrictions in passing values and can also lead to different query plans in special cases:
ANY
is more versatileThe ANY
construct is far more versatile, as it can be combined with various operators, not just =
. Example:
SELECT 'foo' LIKE ANY('{FOO,bar,%oo%}');
For a big number of values, providing a set scales better for each:
Related:
"Find rows where id
is in the given array":
SELECT * FROM tbl WHERE id = ANY (ARRAY[1, 2]);
Inversion: "Find rows where id
is not in the array":
SELECT * FROM tbl WHERE id <> ALL (ARRAY[1, 2]);
SELECT * FROM tbl WHERE id <> ALL ('{1, 2}'); -- equivalent array literal
SELECT * FROM tbl WHERE NOT (id = ANY ('{1, 2}'));
All three equivalent. The first with array constructor, the other two with array literal. The data type can be derived from context unambiguously. Else, an explicit cast may be required, like '{1,2}'::int[]
.
Rows with id IS NULL
do not pass either of these expressions. To include NULL
values additionally:
SELECT * FROM tbl WHERE (id = ANY ('{1, 2}')) IS NOT TRUE;
A lot of correct answers, but I haven't found this one: Collections cannot be sorted, you can only iterate through them.
Now you can iterate over them and create a new sorted something
. Follow the answers here for that.
Another option is to use querySelector('.foo')
or querySelectorAll('.foo')
which have broader browser support than getElementsByClassName
.

When you do new Promise((resolve)...
the type inferred was Promise<{}>
because you should have used new Promise<number>((resolve)
.
It is interesting that this issue was only highlighted when the async
keyword was added. I would recommend reporting this issue to the TS team on GitHub.
There are many ways you can get around this issue. All the following functions have the same behavior:
const whatever1 = () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever2 = async () => {
return new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever3 = async () => {
return await new Promise<number>((resolve) => {
resolve(4);
});
};
const whatever4 = async () => {
return Promise.resolve(4);
};
const whatever5 = async () => {
return await Promise.resolve(4);
};
const whatever6 = async () => Promise.resolve(4);
const whatever7 = async () => await Promise.resolve(4);
In your IDE you will be able to see that the inferred type for all these functions is () => Promise<number>
.

If someone is having issues with creating tables by using files dedicated to each model, be aware of running the "create_all" function from a file different from the one where that function is declared. So, if the filesystem is like this:
Root
--app.py <-- file from which app will be run
--models
----user.py <-- file with "User" model
----order.py <-- file with "Order" model
----database.py <-- file with database and "create_all" function declaration
Be careful about calling the "create_all" function from app.py.
This concept is explained better by the answer to this thread posted by @SuperShoot
If the architecture and linker settings look good, check your h files. My issue was the same error, but I had restructured the h files and I removed an extern statement. Other m files were using that variable, causing the linker error.
why not just pass an data an object with your key/value pairs then you don't have to worry about encoding
$.ajax({
type: "Post",
url: "getdata.php",
data:{
timestamp: timestamp,
uid: id,

Now you can also use Talentsoft.Moq.SetupAsync package https://github.com/TalentSoft/Moq.SetupAsync
Which on the base on the answers found here and ideas proposed to Moq but still not yet implemented here: https://github.com/moq/moq4/issues/384, greatly simplify setup of async methods
Few examples found in previous responses done with SetupAsync extension:
mock.SetupAsync(arg=>arg.DoSomethingAsync());
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Callback(() => { <my code here> });
mock.SetupAsync(arg=>arg.DoSomethingAsync()).Throws(new InvalidOperationException());

if compgen -G "${PROJECT_DIR}/*.png" > /dev/null; then
echo "pattern exists!"
fi
This will work very speedily even in directories with millions of files and does not involve a new subshell.
The simplest should be to rely on ls
return value (it returns non-zero when the files do not exist):
if ls /path/to/your/files* 1> /dev/null 2>&1; then
echo "files do exist"
else
echo "files do not exist"
fi
I redirected the ls
output to make it completely silent.
EDIT: Since this answer has got a bit of attention (and very useful critic remarks as comments), here is an optimization that also relies on glob expansion, but avoids the use of ls
:
for f in /path/to/your/files*; do
## Check if the glob gets expanded to existing files.
## If not, f here will be exactly the pattern above
## and the exists test will evaluate to false.
[ -e "$f" ] && echo "files do exist" || echo "files do not exist"
## This is all we needed to know, so we can break after the first iteration
break
done
This is very similar to @grok12's answer, but it avoids the unnecessary iteration through the whole list.
Here is a nice simple solution using jQuery
that works nicely:
$('.dropdown-toggle').click(function () {
$(this).next('.dropdown-menu').slideToggle(300);
});
$('.dropdown-toggle').focusout(function () {
$(this).next('.dropdown-menu').slideUp(300);
})
The slide animation toggle occurs on clicking and it always slides back up on losing focus.
Alter the 300
value to anything you want, the lower the number the faster the animation.
Edit:
This solution will only work for desktop views. It will need some further modification in order to display nicely for mobile.
After changing the path you have to restart powershell. You do not need to restart your computer.
After trying multiple solutions from around the internet, I was not achieving the exact requirement. So I ended up writing custom utility code. Posting to help someone in future. Tested on swift 4.2
// This function should be called in/after viewDidAppear to let view render
func addArrowImageToButton(button: UIButton, arrowImage:UIImage = #imageLiteral(resourceName: "my_image_name") ) {
let btnSize:CGFloat = 32
let imageView = UIImageView(image: arrowImage)
let btnFrame = button.frame
imageView.frame = CGRect(x: btnFrame.width-btnSize-8, y: btnFrame.height/2 - btnSize/2, width: btnSize, height: btnSize)
button.addSubview(imageView)
//Imageview on Top of View
button.bringSubviewToFront(imageView)
}
If you want to hide overflow on fixed-position elements, the simplest approach I've found is to place the element inside a container element, and apply position:fixed
and overflow:hidden
to that element instead of the contained element (you must remove position:fixed
from the contained element for this to work). The content of the fixed container should then be clipped as expected.
In my case I was having trouble with using object-fit:cover
on a fixed-position element (it was spilling outside the bounds of the page body, regardless of overflow:hidden
). Placing it inside a fixed container with overflow:hidden
on the container fixed the issue.

Sometimes it takes longer to figure out the regex than to just write it out in python:
import string
s = "how much for the maple syrup? $20.99? That's ricidulous!!!"
for char in string.punctuation:
s = s.replace(char, ' ')
If you need other characters you can change it to use a white-list or extend your black-list.
Sample white-list:
whitelist = string.letters + string.digits + ' '
new_s = ''
for char in s:
if char in whitelist:
new_s += char
else:
new_s += ' '
Sample white-list using a generator-expression:
whitelist = string.letters + string.digits + ' '
new_s = ''.join(c for c in s if c in whitelist)

"standard" packaging tools situation is improving recently:
on pypi itself, there are now 48% of wheel packages as of sept. 11th 2015 (up from 38% in may 2015 , 24% in sept. 2014),
the wheel format is now supported out-of-the-box per latest python 2.7.9,
"standard"+"tweaks" packaging tools situation is improving also:
you can find nearly all scientific packages on wheel format at http://www.lfd.uci.edu/~gohlke/pythonlibs,
the mingwpy project may bring one day a 'compilation' package to windows users, allowing to install everything from source when needed.
"Conda" packaging remains better for the market it serves, and highlights areas where the "standard" should improve.
(also, the dependency specification multiple-effort, in standard wheel system and in conda system, or buildout, is not very pythonic, it would be nice if all these packaging 'core' techniques could converge, via a sort of PEP)
You might want to use helper library like http://momentjs.com/ which wraps the native javascript date object for easier manipulations
Then you can do things like:
var day = moment("12-25-1995", "MM-DD-YYYY");
or
var day = moment("25/12/1995", "DD/MM/YYYY");
then operate on the date
day.add('days', 7)
and to get the native javascript date
day.toDate();
The initial size()
of V
will be 0, while int n contains any random value because you don't initialize it.
V.size() < n
is probably false.
Silly me missed the "Enter the amount of numbers you want to evaluate: "
If you enter a n
that's smaller than V.size()
at that time, the loop will terminate.
For POD class members, it makes no difference, it's just a matter of style. For class members which are classes, then it avoids an unnecessary call to a default constructor. Consider:
class A
{
public:
A() { x = 0; }
A(int x_) { x = x_; }
int x;
};
class B
{
public:
B()
{
a.x = 3;
}
private:
A a;
};
In this case, the constructor for B
will call the default constructor for A
, and then initialize a.x
to 3. A better way would be for B
's constructor to directly call A
's constructor in the initializer list:
B()
: a(3)
{
}
This would only call A
's A(int)
constructor and not its default constructor. In this example, the difference is negligible, but imagine if you will that A
's default constructor did more, such as allocating memory or opening files. You wouldn't want to do that unnecessarily.
Furthermore, if a class doesn't have a default constructor, or you have a const
member variable, you must use an initializer list:
class A
{
public:
A(int x_) { x = x_; }
int x;
};
class B
{
public:
B() : a(3), y(2) // 'a' and 'y' MUST be initialized in an initializer list;
{ // it is an error not to do so
}
private:
A a;
const int y;
};
you can use this syntax to redirect all output stderr and stdout to stdout.txt
<cmd> <args> > allout.txt 2>&1
Simple: In Visual Studio Report designer
1. Open the report in design mode and delete the dataset from the RDLC File
2. Open solution Explorer and delete the actual (corrupted) XSD file
3. Add the dataset back to the RDLC file.
4. The above procedure will create the new XSD file.
5. More detailed is below.
In Visual Studio, Open your RDLC file Report in Design mode. Click on the report and then Select View and then Report Data from the top line menu. Select Datasets and then Right Click and delete the dataset from the report. Next Open Solution Explorer, if it is not already open in your Visual Studio. Locate the XSD file (It should be the same name as the dataset you just deleted from the report). Now go back and right click again on the report data Datasets, and select Add Dataset . This will create a new XSD file and write the dataset properties to the report. Now your error message will be gone and any missing data will now appear in your reports.
The order of elements in an array ([]
) is maintained. The order of elements (name:value pairs) in an "object" ({}
) is not, and it's usual for them to be "jumbled", if not by the JSON formatter/parser itself then by the language-specific objects (Dictionary, NSDictionary, Hashtable, etc) that are used as an internal representation.
It can be like this
obj = model.objects.filter(id=emp_id)[0]
or
obj = model.objects.latest('id')

use this command to clear the body of that table: $("#table_id tbody").empty()
I use jquery to load the table content dynamically, and use this command to clear the body when doing the refreshing.
hope this helps you.
Another way of doing it is by using isdigit function. Below is the code for it:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
#include <ctype.h>
#define MAXINPUT 100
int main()
{
char input[MAXINPUT] = "";
int length,i;
scanf ("%s", input);
length = strlen (input);
for (i=0;i<length; i++)
if (!isdigit(input[i]))
{
printf ("Entered input is not a number\n");
exit(1);
}
printf ("Given input is a number\n");
}
First of all, your selector is overkill. I suggest using a class or ID selector like my example below. Once you've corrected your selector, simply use jQuery's .each() to iterate through the collection:
ID Selector:
$('#mytable td').each(function() {
var cellText = $(this).html();
});
Class Selector:
$('.myTableClass td').each(function() {
var cellText = $(this).html();
});
Additional Information:
Take a look at jQuery's selector docs.
It's worth mentioning that the validation properties are different for forms and form elements (note that touched and untouched are for fields only):
Input fields have the following states: $untouched The field has not been touched yet $touched The field has been touched $pristine The field has not been modified yet $dirty The field has been modified $invalid The field content is not valid $valid The field content is valid They are all properties of the input field, and are either true or false. Forms have the following states: $pristine No fields have been modified yet $dirty One or more have been modified $invalid The form content is not valid $valid The form content is valid $submitted The form is submitted They are all properties of the form, and are either true or false.

i think this also will be more helpfull.
for the architecture miss match,
i just copy the jdk file from the 32 bit file ?C:\Program Files (x86)\Java\jdk1.7.0_71 and paste it to the 64 bit file ?C:\Program Files\Java\jdk1.7.0_10, then rename the file to match the file you replace to avoid the IDE error(netbeans)
then your good to go.
note: You should buckup you 64bit files so when you want to create 64 bit application you can return it to its location

Actually, with strings, you can do something like this:
oldStr = 'Hello World!'
newStr = ''
for i in oldStr:
if 'a' < i < 'z':
newStr += chr(ord(i)-32)
else:
newStr += i
print(newStr)
'HELLO WORLD!'
Basically, I'm "adding"+"strings" together into a new string :).
The way I think about it is that you use flatMap
when the function you wanted to put inside of map()
returns an Observable
. In which case you might still try to use map()
but it would be unpractical. Let me try to explain why.
If in such case you decided to stick with map
, you would get an Observable<Observable<Something>>
. For example in your case, if we used an imaginary RxGson library, that returned an Observable<String>
from it's toJson()
method (instead of simply returning a String
) it would look like this:
Observable.from(jsonFile).map(new Func1<File, Observable<String>>() {
@Override public Observable<String>> call(File file) {
return new RxGson().toJson(new FileReader(file), Object.class);
}
}); // you get Observable<Observable<String>> here
At this point it would be pretty tricky to subscribe()
to such an observable. Inside of it you would get an Observable<String>
to which you would again need to subscribe()
to get the value. Which is not practical or nice to look at.
So to make it useful one idea is to "flatten" this observable of observables (you might start to see where the name _flat_Map comes from). RxJava provides a few ways to flatten observables and for sake of simplicity lets assume merge is what we want. Merge basically takes a bunch of observables and emits whenever any of them emits. (Lots of people would argue switch would be a better default. But if you're emitting just one value, it doesn't matter anyway.)
So amending our previous snippet we would get:
Observable.from(jsonFile).map(new Func1<File, Observable<String>>() {
@Override public Observable<String>> call(File file) {
return new RxGson().toJson(new FileReader(file), Object.class);
}
}).merge(); // you get Observable<String> here
This is a lot more useful, because subscribing to that (or mapping, or filtering, or...) you just get the String
value. (Also, mind you, such variant of merge()
does not exist in RxJava, but if you understand the idea of merge then I hope you also understand how that would work.)
So basically because such merge()
should probably only ever be useful when it succeeds a map()
returning an observable and so you don't have to type this over and over again, flatMap()
was created as a shorthand. It applies the mapping function just as a normal map()
would, but later instead of emitting the returned values it also "flattens" (or merges) them.
That's the general use case. It is most useful in a codebase that uses Rx allover the place and you've got many methods returning observables, which you want to chain with other methods returning observables.
In your use case it happens to be useful as well, because map()
can only transform one value emitted in onNext()
into another value emitted in onNext()
. But it cannot transform it into multiple values, no value at all or an error. And as akarnokd wrote in his answer (and mind you he's much smarter than me, probably in general, but at least when it comes to RxJava) you shouldn't throw exceptions from your map()
. So instead you can use flatMap()
and
return Observable.just(value);
when all goes well, but
return Observable.error(exception);
when something fails.
See his answer for a complete snippet: https://stackoverflow.com/a/30330772/1402641

If property hibernate.ddl-auto = update
, then it will not create the tables automatically.
To create tables automatically, you need to set the property to
hibernate.ddl-auto = create
The list of option which is used in the spring boot are
validate: validate the schema, makes no changes to the database.
update: update the schema.
create: creates the schema, destroying previous data.
create-drop: drop the schema at the end of the session
none: is all other cases
So for the first time you can set it to create and then next time on-wards you should set it to update.
EventEmitter
is a public, documented type in the final Angular Core API. Whether or not it is based on Observable
is irrelevant; if its documented emit
and subscribe
methods suit what you need, then go ahead and use it.
As also stated in the docs:
Uses Rx.Observable but provides an adapter to make it work as specified here: https://github.com/jhusain/observable-spec
Once a reference implementation of the spec is available, switch to it.
So they wanted an Observable
like object that behaved in a certain way, they implemented it, and made it public. If it were merely an internal Angular abstraction that shouldn't be used, they wouldn't have made it public.
There are plenty of times when it's useful to have an emitter which sends events of a specific type. If that's your use case, go for it. If/when a reference implementation of the spec they link to is available, it should be a drop-in replacement, just as with any other polyfill.
Just be sure that the generator you pass to the subscribe()
function follows the linked spec. The returned object is guaranteed to have an unsubscribe
method which should be called to free any references to the generator (this is currently an RxJs Subscription
object but that is indeed an implementation detail which should not be depended on).
export class MyServiceEvent {
message: string;
eventId: number;
}
export class MyService {
public onChange: EventEmitter<MyServiceEvent> = new EventEmitter<MyServiceEvent>();
public doSomething(message: string) {
// do something, then...
this.onChange.emit({message: message, eventId: 42});
}
}
export class MyConsumer {
private _serviceSubscription;
constructor(private service: MyService) {
this._serviceSubscription = this.service.onChange.subscribe({
next: (event: MyServiceEvent) => {
console.log(`Received message #${event.eventId}: ${event.message}`);
}
})
}
public consume() {
// do some stuff, then later...
this.cleanup();
}
private cleanup() {
this._serviceSubscription.unsubscribe();
}
}
All of the strongly-worded doom and gloom predictions seem to stem from a single Stack Overflow comment from a single developer on a pre-release version of Angular 2.
Place the logo in your public folder under e.g. public/img/logo.png and then refer to the public folder as %PUBLIC_URL%:
<img src="%PUBLIC_URL%/img/logo.png"/>
The use of %PUBLIC_URL% in the above will be replaced with the URL of the public
folder during the build. Only files inside the public
folder can be referenced from the HTML.
Unlike "/img/logo.png" or "logo.png", "%PUBLIC_URL%/img/logo.png" will work correctly both with client-side routing and a non-root public URL. Learn how to configure a non-root public URL by running npm run build
.
Swift 3.0:

let fileManager = FileManager.default
let nsDocumentDirectory = FileManager.SearchPathDirectory.documentDirectory
let nsUserDomainMask = FileManager.SearchPathDomainMask.userDomainMask
let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
guard let dirPath = paths.first else {
return
}
let filePath = "\(dirPath)/\(itemName).\(fileExtension)"
do {
try fileManager.removeItem(atPath: filePath)
} catch let error as NSError {
print(error.debugDescription)
}}
Thanks to @Anil Varghese, I wrote very similiar code in swift 2.0:
static func removeImage(itemName:String, fileExtension: String) {
let fileManager = NSFileManager.defaultManager()
let nsDocumentDirectory = NSSearchPathDirectory.DocumentDirectory
let nsUserDomainMask = NSSearchPathDomainMask.UserDomainMask
let paths = NSSearchPathForDirectoriesInDomains(nsDocumentDirectory, nsUserDomainMask, true)
guard let dirPath = paths.first else {
return
}
let filePath = "\(dirPath)/\(itemName).\(fileExtension)"
do {
try fileManager.removeItemAtPath(filePath)
} catch let error as NSError {
print(error.debugDescription)
}
}
As of Python 3.5, you can merge two dicts with:
merged = {**dictA, **dictB}
(https://www.python.org/dev/peps/pep-0448/)
So:
jsonMerged = {**json.loads(jsonStringA), **json.loads(jsonStringB)}
asString = json.dumps(jsonMerged)
etc.

I encountered a similar problem, I moved the project directory, resulting in installation failure, my solution is as follows: Build->ReBuild
SimpleDateFormat parseFormat = new SimpleDateFormat("hh:mm a");
provided by Bart Kiers answer should be replaced with somethig like
SimpleDateFormat parseFormat = new SimpleDateFormat("hh:mm a",Locale.UK);
Several of the other answers come close, but honestly, I think you're better off going with the cleanest, simplest syntax. The OP requested a means of exporting a class in ES6 / ES2015. I don't think you can get much cleaner than this:
'use strict';
export default class ClassName {
constructor () {
}
}
No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.
First, create your queue:
Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();
Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):
YourProducer producer = new YourProducer(queue);
and:
YourConsumer consumer = new YourConsumer(queue);
and add stuff to it in your producer:
queue.offer(myObject);
and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):
YourObject myObject = queue.poll();
For more info see the Javadoc
If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.
If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:
Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());
A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.
Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:
BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();
queue.put(myObject); // Blocks until queue isn't full.
YourObject myObject = queue.take(); // Blocks until queue isn't empty.
Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.
Check it out in this demo fiddle, go ahead and change the dropdown or default values in the code.
Setting the passenger.Title
with a value that equals to a title.Value
should work.
View:
<select [(ngModel)]="passenger.Title">
<option *ngFor="let title of titleArray" [value]="title.Value">
{{title.Text}}
</option>
</select>
TypeScript used:
class Passenger {
constructor(public Title: string) { };
}
class ValueAndText {
constructor(public Value: string, public Text: string) { }
}
...
export class AppComponent {
passenger: Passenger = new Passenger("Lord");
titleArray: ValueAndText[] = [new ValueAndText("Mister", "Mister-Text"),
new ValueAndText("Lord", "Lord-Text")];
}
unique_ptr doesn't have the traditional copy constructor. Instead it has a "move constructor" that uses rvalue references:
unique_ptr::unique_ptr(unique_ptr && src);
An rvalue reference (the double ampersand) will only bind to an rvalue. That's why you get an error when you try to pass an lvalue unique_ptr to a function. On the other hand, a value that is returned from a function is treated as an rvalue, so the move constructor is called automatically.
By the way, this will work correctly:
bar(unique_ptr<int>(new int(44));
The temporary unique_ptr here is an rvalue.
In Bootstrap 4, the correct way to border your elements is to name them as follows in the class list of your elements:
For a slight rounding effect on all corners; class="rounded"
For a slight rounding on the left; class="rounded-left"
For a slight rounding on the top; class="rounded-top"
For a slight rounding on the right; class="rounded-right"
For a slight rounding on the bottom; class="rounded-bottom"
For a circle rounding, i.e. your element is made circular; class="rounded-circle"
And to remove rounding effects; class="rounded-0"
To use Bootstrap 4 css files, you can simply use the CDN, and use the following link in the of your HTML file:
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
This will provided you with the basics of Bootstrap 4. However if you would like to use the majority of Bootstrap 4 components, including tooltips, popovers, and dropdowns, then you are best to use the following code instead:
<script src="https://code.jquery.com/jquery-3.3.1.slim.min.js" integrity="sha384-q8i/X+965DzO0rT7abK41JStQIAqVgRVzpbzo5smXKp4YfRvH+8abtTE1Pi6jizo" crossorigin="anonymous"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.3/umd/popper.min.js" integrity="sha384-ZMP7rVo3mIykV+2+9J3UJ46jBk0WLaUAdn689aCwoqbBJiSnjAK/l8WvCWPIPm49" crossorigin="anonymous"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.3/js/bootstrap.min.js" integrity="sha384-ChfqqxuZUCnJSK3+MXmPNIyE6ZbWh2IMqE241rYiqJxyMiZ6OW/JmZQ5stwEULTy" crossorigin="anonymous"></script>
Alternatively, you can install Bootstrap using NPM, or Bower, and link to the files there.
*Note that the bottom tag of the three is the same as the first tag in the first link path.
A full working example, could be :
<img src="path/to/my/image/image.jpg" width="150" height="150" class="rounded-circle mx-auto">
In the above example, the image is centered by using the Bootstrap auto margin on left and right.
Another way to find all View:
SELECT DISTINCT table_name FROM information_schema.TABLES WHERE table_type = 'VIEW'
The measurements are nice, but you are going to get significantly different results depending on what you're doing exactly in your inner loop. Measure your own situation. If you're using multi-threading, that alone is a non-trivial activity.
If the child is always going to be a specific tag then you could do it like this
function test(el)
{
var children = el.getElementsByTagName('div');// any tag could be used here..
for(var i = 0; i< children.length;i++)
{
if (children[i].getAttribute('id') == 'child') // any attribute could be used here
{
// do what ever you want with the element..
// children[i] holds the element at the moment..
}
}
}
First of all, you would have to allocate memory:
char * S = new char[R.length() + 1];
then you can use strcpy
with S
and R.c_str()
:
std::strcpy(S,R.c_str());
You can also use R.c_str()
if the string doesn't get changed or the c string is only used once. However, if S
is going to be modified, you should copy the string, as writing to R.c_str()
results in undefined behavior.
Note: Instead of strcpy
you can also use str::copy
.
<%@ taglib uri="http://java.sun.com/jsp/jstl/functions" prefix="fn"%>

I believe the original post was about removing the space between the buttons in a row, not adding space.
The trick is that the minimum space between the buttons was due to padding built into the buttons as part of the material design specification.
So, don't use buttons! But a GestureDetector instead. This widget type give the onClick
/ onTap
functionality but without the styling.
See this post for an example.
There is no way to create a file without opening it There is os.mknod("newfile.txt")
(but it requires root privileges on OSX). The system call to create a file is actually open()
with the O_CREAT
flag. So no matter how, you'll always open the file.
So the easiest way to simply create a file without truncating it in case it exists is this:
open(x, 'a').close()
Actually you could omit the .close()
since the refcounting GC of CPython will close it immediately after the open()
statement finished - but it's cleaner to do it explicitely and relying on CPython-specific behaviour is not good either.
In case you want touch
's behaviour (i.e. update the mtime in case the file exists):
import os
def touch(path):
with open(path, 'a'):
os.utime(path, None)
You could extend this to also create any directories in the path that do not exist:
basedir = os.path.dirname(path)
if not os.path.exists(basedir):
os.makedirs(basedir)
First, lets extend the string object. Thanks to Ricardo Peres for the prototype, I think using the variable 'string' works better than 'needle' in the context of making it more readable.
String.prototype.beginsWith = function (string) {
return(this.indexOf(string) === 0);
};
Then you use it like this. Caution! Makes the code extremely readable.
var pathname = window.location.pathname;
if (pathname.beginsWith('/sub/1')) {
// Do stuff here
}
yeah it works for me as well.
Note : we need to use window.parent.document
$("button", window.parent.document).click(function()
{
alert("Functionality defined by def");
});
Class.getResources
would retrieve the resource by the classloader which load the object. While ClassLoader.getResource
would retrieve the resource using the classloader specified.
You could use a namedtuple instead of a dict. This is a shorthand for using a data class. Instead of
person = {'name': 'John', 'age': 14}
...do:
from collections import namedtuple
Person = namedtuple('person', ['name', 'age'])
p = Person(name='John', age=14)
p.name # 'John'
This is the same as writing a class that just holds data. In general I would avoid using dicts in django templates because they are awkward.
Swift 3 solution:
let languages = ["bs", "zh-Hant", "en", "fi", "ko", "lv", "ms", "pl", "pt-BR", "ru", "sr-Latn", "sk", "es", "tr"]
UserDefaults.standard.set([languages[0]], forKey: "AppleLanguages")
Gave some examples of language codes that can be used. Hope this helps
You don't need to learn JPA. You can use my easy-criteria for JPA2 (https://sourceforge.net/projects/easy-criteria/files/). Here is the example
CriteriaComposer<Pet> petCriteria CriteriaComposer.from(Pet.class).
where(Pet_.type, EQUAL, "Cat").join(Pet_.owner).where(Ower_.name,EQUAL, "foo");
List<Pet> result = CriteriaProcessor.findAllEntiry(petCriteria);
OR
List<Tuple> result = CriteriaProcessor.findAllTuple(petCriteria);
<input type="text" disabled="disabled" />
See the W3C HTML Specification on the input tag for more information.
Ignoring issues surrounding dict ordering, this might be better:
next(dict.itervalues())
This way we avoid item lookup and generating a list of keys that we don't use.
next(iter(dict.values()))
I am not sure it is the best solution, but it works fine:
if($someObject['length']!=0){
//do someting
}
If you have only 1 form in you page, use this. You do not need to know id or name of the form. I just used this code - working:

Here's a solution using ImmutableJS, where items
is an Immutable List and size
is the required grouping size.
const partition = ((items, size) => {
return items.groupBy((items, i) => Math.floor(i/size))

Try this:
;WITH CTE AS (
SELECT DISTINCT id FROM table WHERE fid = 64
)
SELECT id, ROW_NUMBER() OVER (ORDER BY id) AS RowNum

As a Ruby and Perl developer and learning-Python guy, I haven't found easy_install or pip to be the equivalent to RubyGems or CPAN.
I tend to keep my development systems running the latest versions of modules as the developers update them, and freeze my production systems at set versions. Both RubyGems and CPAN make it easy to find modules by listing what's available, then install and later update them individually or in bulk if desired.
easy_install and pip make it easy to install a module ONCE I located it via a browser search or learned about it by some other means, but they won't tell me what is available. I can explicitly name the module to be updated, but the apps won't tell me what has been updated nor will they update everything in bulk if I want.
So, the basic functionality is there in pip and easy_install but there are features missing that I'd like to see that would make them friendlier and easier to use and on par with CPAN and RubyGems.
I am surprised no-one has suggested using itertools.accumulate
with operator.mul
. This avoids using reduce
, which is different for Python 2 and 3 (due to the functools
import required for Python 3), and moreover is considered un-pythonic by Guido van Rossum himself:
from itertools import accumulate
from operator import mul
def prod(lst):
for value in accumulate(lst, mul):
pass
return value
Example:
prod([1,5,4,3,5,6])
# 1800
Objects in JavaScript can be thought of as associative arrays, mapping keys (properties) to values.
To remove a property from an object in JavaScript you use the delete
operator:
const o = { lastName: 'foo' }
o.hasOwnProperty('lastName') // true
delete o['lastName']
o.hasOwnProperty('lastName') // false
Note that when delete
is applied to an index property of an Array
, you will create a sparsely populated array (ie. an array with a missing index).
When working with instances of Array
, if you do not want to create a sparsely populated array - and you usually don't - then you should use Array#splice
or Array#pop
.
Note that the delete
operator in JavaScript does not directly free memory. Its purpose is to remove properties from objects. Of course, if a property being deleted holds the only remaining reference to an object o
, then o
will subsequently be garbage collected in the normal way.
Using the delete
operator can affect JavaScript engines' ability to optimise code.
So, this is the latest solution if anyone get's stuck like I did today especially, for R.Java
file.

Well, the short answer is no. But you definitely can have multiple res

On windows, I installed pip downloaded from www.lfd.uci.edu/~gohlke/pythonlibs/ then encontered this problem.
So I should have installed setuptools(easy_install) first.

Below mentioned small test might help you understand one aspect of difference between IQueryable<T>
and IEnumerable<T>
. I've reproduced this answer from this post where I was trying to add corrections to someone else's post
I created following structure in DB (DDL script):
CREATE TABLE [dbo].[Employee]([PersonId] [int] NOT NULL PRIMARY KEY,[Salary] [int] NOT NULL)
Here is the record insertion script (DML script):
INSERT INTO [EfTest].[dbo].[Employee] ([PersonId],[Salary])VALUES(1, 20)
INSERT INTO [EfTest].[dbo].[Employee] ([PersonId],[Salary])VALUES(2, 30)
INSERT INTO [EfTest].[dbo].[Employee] ([PersonId],[Salary])VALUES(3, 40)
INSERT INTO [EfTest].[dbo].[Employee] ([PersonId],[Salary])VALUES(4, 50)
INSERT INTO [EfTest].[dbo].[Employee] ([PersonId],[Salary])VALUES(5, 60)
GO
Now, my goal was to simply get top 2 records from Employee
table in database. I added an ADO.NET Entity Data Model item into my console application pointing to Employee
table in my database and started writing LINQ queries.
Code for IQueryable route:
using (var efContext = new EfTestEntities())
{
IQueryable<int> employees = from e in efContext.Employees select e.Salary;
employees = employees.Take(2);
foreach (var item in employees)
{
Console.WriteLine(item);
}
}
When I started to run this program, I had also started a session of SQL Query profiler on my SQL Server instance and here is the summary of execution:
SELECT TOP (2) [c].[Salary] AS [Salary] FROM [dbo].[Employee] AS [c]
It is just that IQueryable
is smart enough to apply the Top (2)
clause on database server side itself so it brings only 2 out of 5 records over the wire. Any further in-memory filtering is not required at all on client computer side.
Code for IEnumerable route:
using (var efContext = new EfTestEntities())
{
IEnumerable<int> employees = from e in efContext.Employees select e.Salary;
employees = employees.Take(2);
foreach (var item in employees)
{
Console.WriteLine(item);
}
}
Summary of execution in this case:
SELECT [Extent1].[Salary] AS [Salary]
FROM [dbo].[Employee] AS [Extent1]
Now the thing is IEnumerable
brought all the 5 records present in Salary
table and then performed an in-memory filtering on the client computer to get top 2 records. So more data (3 additional records in this case) got transferred over the wire unnecessarily.
No magic involved, just subtract from the offset top of the element
$('html, body').animate({scrollTop: $('#contact').offset().top -100 }, 'slow');
just disable eslint for the next line;
useEffect(() => {
fetchBusinesses();
// eslint-disable-next-line
}, []);
in this way you are using it just like a component did mount (called once)
updated
or
const fetchBusinesses = useCallback(() => {
// your logic in here
}, [someDeps])
useEffect(() => {
fetchBusinesses();
// no need to skip eslint warning
}, [fetchBusinesses]);
fetchBusinesses will be called everytime someDeps will change

ok, so my problem was that I tried to install the package with yum which is the primary tool for getting, installing, deleting, querying, and managing Red Hat Enterprise Linux RPM software packages from official Red Hat software repositories, as well as other third-party repositories.
But I'm using ubuntu and The usual way to install packages on the command line in Ubuntu is with apt-get. so the right command was:
sudo apt-get install libstdc++.i686
None of the above solutions resolved this error for me. I had to set the following in web.config:

After pruning, you can get the list of remote branches with git branch -r
. The list of branches with their remote tracking branch can be retrieved with git branch -vv
. So using these two lists you can find the remote tracking branches that are not in the list of remotes.
This line should do the trick (requires bash
or zsh
, won't work with standard Bourne shell):
git branch -r | awk '{print $1}' | egrep -v -f /dev/fd/0 <(git branch -vv | grep origin) | awk '{print $1}' | xargs git branch -d
This string gets the list of remote branches and passes it into egrep
through the standard input. And filters the branches that have a remote tracking branch (using git branch -vv
and filtering for those that have origin
) then getting the first column of that output which will be the branch name. Finally passing all the branch names into the delete branch command.
Since it is using the -d
option, it will not delete branches that have not been merged into the branch that you are on when you run this command.
Also remember that you'll need to run git fetch --prune
first, otherwise git branch -r
will still see the remote branches.
The quickest solution is: set environment variable RANDFILE to path where the 'random state' file can be written (of course check the file access permissions), eg. in your command prompt:
set RANDFILE=C:\MyDir\.rnd
openssl genrsa -out my-prvkey.pem 1024
More explanations: OpenSSL on Windows tries to save the 'random state' file in the following order:
I'm pretty sure that in your case it ends up trying to save it in C:\.rnd (and it fails because lack of sufficient access rights). Unfortunately OpenSSL does not print the path that is actually tries to use in any error messages.
With $("div.desc").hide();
you are essentially trying to hide a div with a class name of desc
. Which doesn't exist. With $("#"+test).show();
you are trying to show either a div with an id of #2
or #3
. Those are illegal id's in HTML (can't start with a number), though they will work in many browsers. However, they don't exist.
I'd rename the two divs to carDiv2
and carDiv3
and then use different logic to hide or show.
if((test) == 2) { ... }
Also, use a class for your checkboxes so your binding becomes something like
$('.carCheckboxes').click(function ...
There is no way (to my knowledge) to trigger the download window in your browser from Javascript. The only way to do it is to redirect the browser to a url that streams the file to the browser.
If you can modify your REST service, you might be able to solve it by changing so the POST request doesn't respond with the binary file, but with a url to that file. That'll get you the url in Javascript instead of the binary data, and you can redirect the browser to that url, which should prompt the download without leaving the original page.
Instead of replace we can force culture like
var x = decimal.Parse("18,285", new NumberFormatInfo() { NumberDecimalSeparator = "," });
it will give output 18.285
This question actually is not JSP related, it is HTTP related. you can just do:

i found that i had a timer running in the background. when the activity is killed, yet the timer still running. in the timer finish callback i access fragment object to do some work, and here is the bug!!!! the fragment exists but the activity isn't.
if you have service of timer or any background threads, make sure to not access fragments objects.
setState(updater[, callback])
is an async function:
https://facebook.github.io/react/docs/react-component.html#setstate
You can execute a function after setState is finishing using the second param callback
like:
this.setState({
someState: obj
}, () => {
this.afterSetStateFinished();
});
The same can be done with hooks in React functional component:
https://github.com/the-road-to-learn-react/use-state-with-callback#usage
Look at useStateWithCallbackLazy:
import { useStateWithCallbackLazy } from 'use-state-with-callback';
const [count, setCount] = useStateWithCallbackLazy(0);
setCount(count + 1, () => {
afterSetCountFinished();
});
As Ben said, you are POSTing your request ( HttpMethod.Post specified in your code )
The querystring (get) parameters included in your url probably will not do anything.
Try this:
string url = "http://myserver/method";
string content = "param1=1¶m2=2";
HttpClientHandler handler = new HttpClientHandler();
HttpClient httpClient = new HttpClient(handler);
HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Post, url);
HttpResponseMessage response = await httpClient.SendAsync(request,content);

.gallery_wrapper{
width: 958px;
margin: 0 auto;
}
/*ul list*/

You may also want to :
if you want to apply separate css classes for same element with conditions in Vue.js you can use the below given method.it worked in my scenario.
html
<div class="Main" v-bind:class="{ Sub: page}" >
in here, Main and Sub are two different class names for same div element. v-bind:class directive is used to bind the sub class in here. page is the property we use to update the classes when it's value changed.
js
data:{
page : true;
}
here we can apply a condition if we needed. so, if the page property becomes true element will go with Main and Sub claases css styles. but if false only Main class css styles will be applied.
The answer lies within the Java Documentation's Tutorial for Writing/Saving an Image.
The Image I/O
class provides the following method for saving an image:
static boolean ImageIO.write(RenderedImage im, String formatName, File output) throws IOException
The tutorial explains that
The BufferedImage class implements the RenderedImage interface.
so it's able to be used in the method.
For example,
try {
BufferedImage bi = getMyImage(); // retrieve image
File outputfile = new File("saved.png");
ImageIO.write(bi, "png", outputfile);
} catch (IOException e) {
// handle exception
}
It's important to surround the write
call with a try block because, as per the API, the method throws an IOException
"if an error occurs during writing"
Also explained are the method's objective, parameters, returns, and throws, in more detail:
Writes an image using an arbitrary ImageWriter that supports the given format to a File. If there is already a File present, its contents are discarded.
Parameters:
im - a RenderedImage to be written.
formatName - a String containg the informal name of the format.
output - a File to be written to.
Returns:
false if no appropriate writer is found.
Throws:
IllegalArgumentException - if any parameter is null.
IOException - if an error occurs during writing.
However, formatName
may still seem rather vague and ambiguous; the tutorial clears it up a bit:
The ImageIO.write method calls the code that implements PNG writing a “PNG writer plug-in”. The term plug-in is used since Image I/O is extensible and can support a wide range of formats.
But the following standard image format plugins : JPEG, PNG, GIF, BMP and WBMP are always be present.
For most applications it is sufficient to use one of these standard plugins. They have the advantage of being readily available.
There are, however, additional formats you can use:
The Image I/O class provides a way to plug in support for additional formats which can be used, and many such plug-ins exist. If you are interested in what file formats are available to load or save in your system, you may use the getReaderFormatNames and getWriterFormatNames methods of the ImageIO class. These methods return an array of strings listing all of the formats supported in this JRE.
String writerNames[] = ImageIO.getWriterFormatNames();
The returned array of names will include any additional plug-ins that are installed and any of these names may be used as a format name to select an image writer.
For a full and practical example, one can refer to Oracle's SaveImage.java
example.
may be this will help:
map.setCenter(window.markersArray[2].getPosition());
all the markers info are in markersArray array and it is global. So you can access it from anywhere using window.variablename. Each marker has a unique id and you can put that id in the key of array. so you create marker like this:
window.markersArray[2] = new google.maps.Marker({
position: new google.maps.LatLng(23.81927, 90.362349),
map: map,
title: 'your info '
});
Hope this will help.

When there are multiple activities entries in AndroidManifest.xml, how does android know which activity to start first?
There is no "first". In your case, with your manifest as shown, you will have two icons in your launcher. Whichever one the user taps on is the one that gets launched.
I could not understand intent-filters. Can anyone please explain.
There is quite a bit of documentation on the subject. Please consider reading that, then asking more specific questions.
Also, when you get "application has stopped unexpectedly, try again", use adb logcat
, DDMS, or the DDMS perspective in Eclipse to examine the Java stack trace associated with the error.
We can append or prepend two lists or list&array
Append:
var l = List(1,2,3)
l = l :+ 4
Result : 1 2 3 4
var ar = Array(4, 5, 6)
for(x <- ar)
{ l = l :+ x }
l.foreach(println)
Result:1 2 3 4 5 6
Prepending:
var l = List[Int]()
for(x <- ar)
{ l= x :: l } //prepending
l.foreach(println)
Result:6 5 4 1 2 3
You can use dataSrc :
Here is a typical example of datatables.net
var table = $('#example').DataTable( {
"ajax": {
"type" : "GET",
"url" : "ajax.php",
"dataSrc": function ( json ) {
//Make your callback here.
alert("Done!");
return json.data;
}
},
"columns": [
{ "data": "name" },
{ "data": "position" },
{ "data": "office" },
{ "data": "extn" },
{ "data": "start_date" },
{ "data": "salary" }
]
} );

I tried sudo apt install nginx-full. You will get all the required packages.
I was able to get the original bundle identifier to work on my paid team membership account (after having it assigned to my personal team) by revoking the personal team signing certificate that was assigned to the same account id.
This won't work if you still need the certificate for other apps.
Try with this:
msg.setContent(email.getBody(), "text/html; charset=ISO-8859-1");
you can use paste0 or cat method to combine string with variable values in R
For Example:
paste0("Value of A : ", a)
cat("Value of A : ", a)
best bet is targeting features not devices unless you have to, bootstrap do well and you can extend on their breakpoints, for instance targeting pixel density and larger screens above 1920
I think this is important to consider for cross-platform execution, i.e. as a CYA. :)
On Windows, 'b' appended to the mode opens the file in binary mode, so there are also modes like 'rb', 'wb', and 'r+b'. Python on Windows makes a distinction between text and binary files; the end-of-line characters in text files are automatically altered slightly when data is read or written. This behind-the-scenes modification to file data is fine for ASCII text files, but it’ll corrupt binary data like that in JPEG or EXE files. Be very careful to use binary mode when reading and writing such files. On Unix, it doesn’t hurt to append a 'b' to the mode, so you can use it platform-independently for all binary files.
This is directly quoted from Python Software Foundation 2.7.x.
Use the following code to ensure the response is in JSON format (PHP version)...
header('Content-Type: application/json');
echo json_encode($return_vars);
exit;
You can split string to the words and check the result list.
if word in string.split():
print 'success'
I know this not a .net solution but here it comes anyways. Maybe it comes handy for people that have windows 10 and want a faster solution. For example if you run this command con your command prompt or by pressing winKey + R
:
bash -c "du -sh /mnt/c/Users/; sleep 5"
The sleep 5
is so you have time to see the results and the windows does not closes
In my computer that displays:
Note at the end how it shows 85G (85 Gigabytes). It is supper fast compared to doing it with .Net. If you want to see the size more accurately remove the h
which stands for human readable.
So just do something like Processes.Start("bash",... arguments)
That is not the exact code but you get the idea.
The toggleOption function is not perfect and introduced nasty bugs in my application. jQuery will get confused with .val() and .arraySerialize() Try to select options 4 and 5 to see what I mean:
<select id="t">
<option value="v1">options 1</option>
<option value="v2">options 2</option>
<option value="v3" id="o3">options 3</option>
<option value="v4">options 4</option>
<option value="v5">options 5</option>
</select>
<script>
jQuery.fn.toggleOption = function( show ) {
jQuery( this ).toggle( show );
if( show ) {
if( jQuery( this ).parent( 'span.toggleOption' ).length )
jQuery( this ).unwrap( );
} else {
jQuery( this ).wrap( '<span class="toggleOption" style="display: none;" />' );
}
};
$("#o3").toggleOption(false);
$("#t").change(function(e) {
if($(this).val() != this.value) {
console.log("Error values not equal", this.value, $(this).val());
}
});
</script>
Just to add to things from several of the posts above:
read() -- at least on my system -- returns ssize_t. This is like size_t, except is signed. On my system, it's a long, not an int. You might get compiler warnings if you use int, depending on your system, your compiler, and what warnings you have turned on.
import csv
def read_cell(x, y):
with open('file.csv', 'r') as f:
reader = csv.reader(f)
y_count = 0
for n in reader:
if y_count == y:
cell = n[x]
return cell
y_count += 1
print (read_cell(4, 8))
This example prints cell 4, 8 in Python 3.
You cannot style a variable such as $ip['countryName']
You can only style elements like p,div, etc, or classes and ids.
If you want to style $ip['countryName'] there are several ways.
You can echo it within an element:
echo '<p id="style">'.$ip['countryName'].'</p>';
echo '<span id="style">'.$ip['countryName'].'</span>';
echo '<div id="style">'.$ip['countryName'].'</div>';
If you want to style both the variables the same style, then set a class like:
echo '<p class="style">'.$ip['cityName'].'</p>';
echo '<p class="style">'.$ip['countryName'].'</p>';
You could also embed the variables within your actual html rather than echoing them out within the code.
$city = $ip['cityName'];
$country = $ip['countryName'];
?>
<div class="style"><?php echo $city ?></div>
<div class="style"><?php echo $country?></div>
You can download the 10.7 Lion JDK from http://connect.apple.com.
Sign in and click the java
section on the right.
The jdk is installed into a different location then previous. This will result in IDEs (such as Eclipse) being unable to locate source code and javadocs.
At the time of writing the JDK ended up here:
/Library/Java/JavaVirtualMachines/1.6.0_26-b03-383.jdk/Contents/Home
Open up eclipse preferences and go to Java --> Installed JREs page
Rather than use the "JVM Contents (MacOS X Default) we will need to use the JDK location
At the time of writing Search is not aware of the new JDK location; we we will need to click on the Add button
From the Add JRE wizard choose "MacOS X VM" for the JRE Type
For the JRE Definition Page we need to fill in the following:
The other fields will now auto fill, with the default JRE name being "Home". You can quickly correct this to something more meaningful:
Finish the wizard and return to the Installed JREs page
Choose "System JDK" from the list
You can now develop normally with:
There is no way to delete or read the past history.
You could try going around it by emulating history in your own memory and calling history.pushState
everytime window popstate
event is emitted (which is proposed by the currently accepted Mike's answer), but it has a lot of disadvantages that will result in even worse UX than not supporting the browser history at all in your dynamic web app, because:
So even if you try going around it by building virtual history, it's very likely that it can also lead into a situation where you have blank history states (to which going back/forward does nothing), or where that going back/forward skips some of your history states totally.
Use this one
public static final MediaType APPLICATION_JSON_UTF8 = new MediaType(MediaType.APPLICATION_JSON.getType(), MediaType.APPLICATION_JSON.getSubtype(), Charset.forName("utf8"));
@Test
public void testInsertObject() throws Exception {
String url = BASE_URL + "/object";
ObjectBean anObject = new ObjectBean();
anObject.setObjectId("33");
anObject.setUserId("4268321");
//... more
ObjectMapper mapper = new ObjectMapper();
mapper.configure(SerializationFeature.WRAP_ROOT_VALUE, false);
ObjectWriter ow = mapper.writer().withDefaultPrettyPrinter();
String requestJson=ow.writeValueAsString(anObject );
mockMvc.perform(post(url).contentType(APPLICATION_JSON_UTF8)
.content(requestJson))
.andExpect(status().isOk());
}
As described in the comments, this works because the object is converted to json and passed as the request body. Additionally, the contentType is defined as Json (APPLICATION_JSON_UTF8).
I hope help you.

There are many ways to create protection against session hijack, however all of them are either reducing user satisfaction or are not secure.
IP and/or X-FORWARDED-FOR checks. These work, and are pretty secure... but imagine the pain of users. They come to an office with WiFi, they get new IP address and lose the session. Got to log-in again.
User Agent checks. Same as above, new version of browser is out, and you lose a session. Additionally, these are really easy to "hack". It's trivial for hackers to send fake UA strings.
localStorage token. On log-on generate a token, store it in browser storage and store it to encrypted cookie (encrypted on server-side). This has no side-effects for user (localStorage persists through browser upgrades). It's not as secure - as it's just security through obscurity. Additionally you could add some logic (encryption/decryption) to JS to further obscure it.
Cookie reissuing. This is probably the right way to do it. The trick is to only allow one client to use a cookie at a time. So, active user will have cookie re-issued every hour or less. Old cookie is invalidated if new one is issued. Hacks are still possible, but much harder to do - either hacker or valid user will get access rejected.

you can do like this in react
handleEvent = (e: React.SyntheticEvent<EventTarget>) => {
const simpleInput = (e.target as HTMLInputElement).value;
//for simple html input values
const formInput = (e.target as HTMLFormElement).files[0];
//for html form elements
}
Often, I like changing current directories while editing - so I have to specify paths less.

Seems like your view is typed dynamic
. Set the right type on the view and you'll see the error go away.
You can reset your branch to the state it was in just before the merge if you find the commit it was on then.
One way is to use git reflog
, it will list all the HEADs you've had.
I find that git reflog --relative-date
is very useful as it shows how long ago each change happened.
Once you find that commit just do a git reset --hard <commit id>
and your branch will be as it was before.
If you have SourceTree, you can look up the <commit id>
there if git reflog
is too overwhelming.
it does not work for me:
$('#Attachment').replaceWith($(this).clone());
or
$('#Attachment').replaceWith($('#Attachment').clone());
so in asp mvc I use razor features for replacing file input. at first create a variable for input string with Id and Name and then use it for showing in page and replacing on reset button click:
@{
var attachmentInput = Html.TextBoxFor(c => c.Attachment, new { type = "file" });
}
@attachmentInput
<button type="button" onclick="$('#@(Html.IdFor(p => p.Attachment))').replaceWith('@(attachmentInput)');">--</button>

The documentation says:
However, JUnit Jupiter’s
org.junit.jupiter.Assertions
class does not provide anassertThat()
method like the one found in JUnit 4’sorg.junit.Assert
class which accepts a HamcrestMatcher
. Instead, developers are encouraged to use the built-in support for matchers provided by third-party assertion libraries.
Example for Hamcrest:
import static org.hamcrest.CoreMatchers.instanceOf;
import static org.hamcrest.MatcherAssert.assertThat;
import org.junit.jupiter.api.Test;
class HamcrestAssertionDemo {
@Test
void assertWithHamcrestMatcher() {
SubClass subClass = new SubClass();
assertThat(subClass, instanceOf(BaseClass.class));
}
}
Example for AssertJ:
import static org.assertj.core.api.Assertions.assertThat;
import org.junit.jupiter.api.Test;
class AssertJDemo {
@Test
void assertWithAssertJ() {
SubClass subClass = new SubClass();
assertThat(subClass).isInstanceOf(BaseClass.class);
}
}
Note that this assumes you want to test behaviors similar to instanceof
(which accepts subclasses). If you want exact equal type, I don’t see a better way than asserting the two class to be equal like you mentioned in the question.
Try doing this :
awk '{print substr($0, 1, length($0)-1)}' file.txt
This is more generic than just removing the final comma but any last character
If you'd want to only remove the last comma with awk :
awk '{gsub(/,$/,""); print}' file.txt
If the script always outputs lines of 10 characters followed by 3 extra (in other words, you just want the first 10 characters), you can use
script | cut -c 1-10
If it outputs an uncertain number of non-space characters, followed by a space and then 2 other extra characters (in other words, you just want the first field), you can use
script | cut -d ' ' -f 1
... as in majhool's comment earlier. Depending on your platform, you may also have colrm, which, again, would work if the lines are a fixed length:
script | colrm 11
You can make a new file under [.git\refs\remotes\origin] with name "HEAD" and put content "ref: refs/remotes/origin/master" to it. This should solve your problem.
It seems that clone from an empty repos will lead to this. Maybe the empty repos do not have HEAD because no commit object exist.
You can use the
git log --remotes --branches --oneline --decorate
to see the difference between each repository, while the "problem" one do not have "origin/HEAD"
Edit: Give a way using command line
You can also use git command line to do this, they have the same result
git symbolic-ref refs/remotes/origin/HEAD refs/remotes/origin/master
If you have a list of lists, you only needed to use ...
import numpy as np
...
npa = np.asarray(someListOfLists, dtype=np.float32)
per this LINK in the scipy / numpy documentation. You just needed to define dtype inside the call to asarray.
Adding to the answer given by @insomniac. You can create a Map
to put the parameter for RequestBody
including image.
Code for Interface
public interface ApiInterface {
@Multipart
@POST("/api/Accounts/editaccount")
Call<User> editUser (@Header("Authorization") String authorization, @PartMap Map<String, RequestBody> map);
}
Code for Java class
File file = new File(imageUri.getPath());
RequestBody fbody = RequestBody.create(MediaType.parse("image/*"), file);
RequestBody name = RequestBody.create(MediaType.parse("text/plain"), firstNameField.getText().toString());
RequestBody id = RequestBody.create(MediaType.parse("text/plain"), AZUtils.getUserId(this));
Map<String, RequestBody> map = new HashMap<>();
map.put("file\"; filename=\"pp.png\" ", fbody);
map.put("FirstName", name);
map.put("Id", id);
Call<User> call = client.editUser(AZUtils.getToken(this), map);
call.enqueue(new Callback<User>() {
@Override
public void onResponse(retrofit.Response<User> response, Retrofit retrofit)
{
AZUtils.printObject(response.body());
}
@Override
public void onFailure(Throwable t) {
t.printStackTrace();
}
});
const regex = new RegExp(`ReGeX${testVar}ReGeX`);
...
string.replace(regex, "replacement");
Per some of the comments, it's important to note that you may want to escape the variable if there is potential for malicious content (e.g. the variable comes from user input)
In 2019, this would usually be written using a template string, and the above code has been updated. The original answer was:
var regex = new RegExp("ReGeX" + testVar + "ReGeX");
...
string.replace(regex, "replacement");
JE
and JZ
are just different names for exactly the same thing: a
conditional jump when ZF
(the "zero" flag) is equal to 1.
(Similarly, JNE
and JNZ
are just different names for a conditional jump
when ZF
is equal to 0.)
You could use them interchangeably, but you should use them depending on what you are doing:
JZ
/JNZ
are more appropriate when you are explicitly testing
for something being equal to zero:
dec ecx
jz counter_is_now_zero
JE
and JNE
are more appropriate after a CMP
instruction:
cmp edx, 42
je the_answer_is_42
(A CMP
instruction performs a subtraction, and throws the value of the result away, while keeping the flags; which is why you get ZF=1
when the operands are equal
and ZF=0
when they're not.)
A minimalist implementation of the \url
macro that uses only Tex primitives:
\def\url#1{\expandafter\string\csname #1\endcsname}
This url absolutely won't break over lines, though; the hypperef package is better for that.
v1.5 and higher
Concatenates multiple input columns together into a single column. The function works with strings, binary and compatible array columns.
Eg: new_df = df.select(concat(df.a, df.b, df.c))
v1.5 and higher
Similar to concat
but uses the specified separator.
Eg: new_df = df.select(concat_ws('-', df.col1, df.col2))
v2.4 and higher
Used to concat maps, returns the union of all the given maps.
Eg: new_df = df.select(map_concat("map1", "map2"))
Using string concat operator (||
):
v2.3 and higher
Eg: df = spark.sql("select col_a || col_b || col_c as abc from table_x")
Reference: Spark sql doc
If you know how far back, you can try something like:
# Current branch vs. parent
git diff HEAD^ HEAD
# Current branch, diff between commits 2 and 3 times back
git diff HEAD~3 HEAD~2
Prior commits work something like this:
# Parent of HEAD
git show HEAD^1
# Grandparent
git show HEAD^2
There are a lot of ways you can specify commits:
# Great grandparent
git show HEAD~3
Try
git stash
This worked for me. It stashes anything you haven't committed and that got around the problem.
To interrupt it, you can try pressing ctrl c to send a SIGINT. If it doesn't stop it, you may try to kill it using kill -9 <pid>
, which sends a SIGKILL. The latter can't be ignored/intercepted by the process itself (the one being killed).
To move the active process to background, you can press ctrl z. The process is sent to background and you get back to the shell prompt. Use the fg
command to do the opposite.
Mike Ash posted a solution (god bless him!) that doesn't require a reboot. Just run:
launchctl list|grep UIKitApplication|awk '{print $3}'|xargs launchctl remove
The above command lists out all launchd jobs, searches for one with UIKitApplication in the name (which will be the job corresponding to your app that's improperly sticking around), extracts the name, and tells launchd to get rid of that job.
INSERT INTO DestTable
SELECT * FROM SourceTable
WHERE ...
works in SQL Server
You can take moment timezone. It lets you set your location and also takes care of daylight saving time.
Since PHP 5.4.0 you can use getallheaders
function which returns all request headers as an associative array:
var_dump(getallheaders());
// array(8) {
// ["Accept"]=>
// string(63) "text/html[...]"
// ["Accept-Charset"]=>
// string(31) "ISSO-8859-1[...]"
// ["Accept-Encoding"]=>
// string(17) "gzip,deflate,sdch"
// ["Accept-Language"]=>
// string(14) "en-US,en;q=0.8"
// ["Cache-Control"]=>
// string(9) "max-age=0"
// ["Connection"]=>
// string(10) "keep-alive"
// ["Host"]=>
// string(9) "localhost"
// ["User-Agent"]=>
// string(108) "Mozilla/5.0 (Windows NT 6.1; WOW64) [...]"
// }
Earlier this function worked only when PHP was running as an Apache/NSAPI module.
As mentioned earlier by firelynx if dtype is explicitly specified and there is mixed data that is not compatible with that dtype then loading will crash. I used a converter like this as a workaround to change the values with incompatible data type so that the data could still be loaded.
def conv(val):
if not val:
return 0
try:
return np.float64(val)
except:
return np.float64(0)
df = pd.read_csv(csv_file,converters={'COL_A':conv,'COL_B':conv})
You can also use a combination of cat
and paste0
cat(paste0("File not supplied.\n", "Usage: ./program F=filename"))
I find this to be more useful when incorporating variables into the printout. For example:
file <- "myfile.txt"
cat(paste0("File not supplied.\n", "Usage: ./program F=", file))
I found this solution more practical
UPDATED for Swift 3
extension UIColor {
static let graySpace = UIColor.init(red: 50/255, green: 50/255, blue: 50/255, alpha: 1.0)
static let redBlood = UIColor.init(red: 102/255, green: 0/255, blue: 0/255, alpha: 1.0)
static let redOrange = UIColor.init(red: 204/255, green: 17/255, blue: 0/255, alpha: 1.0)
func alpha(value : CGFloat) -> UIColor {
var r = CGFloat(0), g = CGFloat(0), b = CGFloat(0), a = CGFloat(0)
self.getRed(&r, green: &g, blue: &b, alpha: &a)
return UIColor(red: r, green: g, blue: b, alpha: value)
}

override func viewDidLoad() {
self.view.backgroundColor = UIColor.graySpace

if you want to kill a specific node process , you can go to command line route and type:
ps aux | grep node
to get a list of all node process ids. now you can get your process id(pid), then do:
kill -9 PID
and if you want to kill all node processes then do:
killall -9 node
-9 switch is like end task on windows. it will force the process to end. you can do:
kill -l
to see all switches of kill command and their comments.
Create a class in your CSS file:
.active {
z-index: 20;
background: rgb(23,55,94)
color: #fff;
}
Then in your jQuery
$(this).addClass("active");
You can use DateTime.ToString Method (String)
DateTime.Now.ToString("yyyyMMddHHmmssfff")
string.Format("{0:yyyy-MM-dd_HH-mm-ss-fff}", DateTime.Now)
;
$"{DateTime.Now:yyyy-MM-dd_HH-mm-ss-fff}"
There are following custom format specifiers y (year), M (month), d (day), h (hour 12), H (hour 24), m (minute), s (second), f (second fraction), F (second fraction, trailing zeroes are trimmed), t (P.M or A.M) and z (time zone).
With Extension Method
Usage:
string result = "myfile.txt".AppendTimeStamp();
//myfile20130604234625642.txt
Extension method
public static class MyExtensions
{
public static string AppendTimeStamp(this string fileName)
{
return string.Concat(
Path.GetFileNameWithoutExtension(fileName),
DateTime.Now.ToString("yyyyMMddHHmmssfff"),
Path.GetExtension(fileName)
);
}
}
Array.prototype.removeAt = function(id) {

}
This should do the trick, jsfiddle
I'm not sure that there is any option for simply printing the full effective search path.
But: the search path consists of directories specified by -L
options on the command line, followed by directories added to the search path by SEARCH_DIR("...")
directives in the linker script(s). So you can work it out if you can see both of those, which you can do as follows:
If you're invoking ld
directly:
-L
options are whatever you've said they are.--verbose
option. Look for the SEARCH_DIR("...")
directives, usually near the top of the output. (Note that these are not necessarily the same for every invocation of ld
-- the linker has a number of different built-in default linker scripts, and chooses between them based on various other linker options.)If you're linking via gcc
:
-v
option to gcc
so that it shows you how it invokes the linker. In fact, it normally does not invoke ld
directly, but indirectly via a tool called collect2
(which lives in one of its internal directories), which in turn invokes ld
. That will show you what -L
options are being used.-Wl,--verbose
to the gcc
options to make it pass --verbose
through to the linker, to see the linker script as described above.This simple example shows how to capture curl output, and use it in a bash script
function main
{
\curl -vs 'http://google.com' 2>&1
# note: add -o /tmp/ignore.png if you want to ignore binary output, by saving it to a file.
}
# capture output of curl to a variable
OUT=$(main)
# search output for something using grep.

I always like to write my own "custom enum". Than I have one class that is a little bit more complex, but I can reuse it:
public abstract class CustomEnum
{
private readonly string _name;
private readonly object _id;
protected CustomEnum( string name, object id )
{
_name = name;
_id = id;
}
public string Name
{
get { return _name; }
}
public object Id
{
get { return _id; }
}
public override string ToString()
{
return _name;
}
}
public abstract class CustomEnum<TEnumType, TIdType> : CustomEnum
where TEnumType : CustomEnum<TEnumType, TIdType>
{
protected CustomEnum( string name, TIdType id )
: base( name, id )
{ }
public new TIdType Id
{
get { return (TIdType)base.Id; }
}
public static TEnumType FromName( string name )
{
try
{
return FromDelegate( entry => entry.Name.Equals( name ) );
}
catch (ArgumentException ae)
{
throw new ArgumentException( "Illegal name for custom enum '" + typeof( TEnumType ).Name + "'", ae );
}
}
public static TEnumType FromId( TIdType id )
{
try
{
return FromDelegate( entry => entry.Id.Equals( id ) );
}
catch (ArgumentException ae)
{
throw new ArgumentException( "Illegal id for custom enum '" + typeof( TEnumType ).Name + "'", ae );
}
}
public static IEnumerable<TEnumType> GetAll()
{
var elements = new Collection<TEnumType>();
var infoArray = typeof( TEnumType ).GetFields( BindingFlags.Public | BindingFlags.Static );
foreach (var info in infoArray)
{
var type = info.GetValue( null ) as TEnumType;
elements.Add( type );
}
return elements;
}
protected static TEnumType FromDelegate( Predicate<TEnumType> predicate )
{
if(predicate == null)
throw new ArgumentNullException( "predicate" );
foreach (var entry in GetAll())
{
if (predicate( entry ))
return entry;
}
throw new ArgumentException( "Element not found while using predicate" );
}
}
Now I just need to create my enum I want to use:
public sealed class SampleEnum : CustomEnum<SampleEnum, int>
{
public static readonly SampleEnum Element1 = new SampleEnum( "Element1", 1, "foo" );
public static readonly SampleEnum Element2 = new SampleEnum( "Element2", 2, "bar" );
private SampleEnum( string name, int id, string additionalText )
: base( name, id )
{
AdditionalText = additionalText;
}
public string AdditionalText { get; private set; }
}
At last I can use it like I want:
static void Main( string[] args )
{
foreach (var element in SampleEnum.GetAll())
{
Console.WriteLine( "{0}: {1}", element, element.AdditionalText );
Console.WriteLine( "Is 'Element2': {0}", element == SampleEnum.Element2 );
Console.WriteLine();
}
Console.ReadKey();
}
And my output would be:
Element1: foo
Is 'Element2': False
Element2: bar
Is 'Element2': True
Check the below lines are present in your web.config file
<system.web>
<httpRuntime requestPathInvalidCharacters="" />
</system.web>
The html
<select id="drop" name="company" class="company btn btn-outline dropdown-toggle" >
<option value="demo1">Group Medical</option>
<option value="demo">Motor Insurance</option>
</select>
Script.js
$("#drop").change(function () {
var category= $('select[name=company]').val() // Here we can get the value of selected item
alert(category);
});
I changed my web.config file to use HTTPMODULE in two forms:
IIS: 6
<httpModules>
<add name="Module" type="app.Module,app"/>
</httpModules>
IIS: 7.5
<system.webServer>
<modules>
<add name="Module" type="app.Module,app"/>
</modules>
</system.webServer>
