Use doubleval()
. But be very careful about using decimals in financial transactions, and validate that user input very carefully.
Here you go:
$('td[id^="' + value +'"]')
so if the value is for instance 'foo'
, then the selector will be 'td[id^="foo"]'
.
Note that the quotes are mandatory: [id^="...."]
.

There is an option in Postman if you download it from https://www.getpostman.com instead of the chrome store (most probably it has been introduced in the new versions and the chrome one will be updated later) not sure about the old ones.
In the settings, turn off the SSL certificate verification option
Be sure to remember to reactivate it afterwards, this is a security feature.
If you really want to use the chrome app, you could always add an exception to chrome for the url: Enter the url you would like to open in the chrome browser, you'll get a warning with a link at the bottom of the page to add an exception, which if you do, it will also allow postman to access your url. But the first option of using the postman stand-alone app is much better.
I hope this can help.
This error of Cannot find the declaration of element 'beans' but for a whole different reason
It turs out my internet connection was not very reliable, so i decided to check first for this url

why reinvent the wheel? use microsoft's json serialize or a 3rd party library such as json.NET
I believe this may be what your looking for:
SELECT padded_id = REPLACE(STR(id, 4), SPACE(1), '0')
FROM tableA
or
SELECT REPLACE(STR(id, 4), SPACE(1), '0') AS [padded_id]
FROM tableA
I haven't tested the syntax on the 2nd example. I'm not sure if that works 100% - it may require some tweaking - but it conveys the general idea of how to obtain your desired output.
EDIT
To address concerns listed in the comments...
@pkr298 - Yes STR does only work on numbers... The OP's field is an ID... hence number only.
@Desolator - Of course that won't work... the First parameter is 6 characters long. You can do something like:
SELECT REPLACE(STR(id,
(SELECT LEN(MAX(id)) + 4 FROM tableA)), SPACE(1), '0') AS [padded_id] FROM tableA
this should theoretically move the goal posts... as the number gets bigger it should ALWAYS work.... regardless if its 1 or 123456789...
So if your max value is 123456... you would see 0000123456 and if your min value is 1 you would see 0000000001

Presumably, you want to convert values before the decimal place to an integer. If so, use case
and check for the right format:
SELECT (case when varcharcol not like '%.%' then cast(varcharcol as int)
else cast(left(varcharcol, chardindex('.', varcharcol) - 1) as int)
end) IntVal

I found a way to display activity Indicator with minimum code:
first of all import your UI Kit
import UIKit;
Then you have to initiate activity indicator
let activityIndicator:UIActivityIndicatorView = UIActivityIndicatorView();
Then just copy paste this functions below which are self explainatory and call them whereever you need them:
func startLoading(){
activityIndicator.center = self.view.center;
activityIndicator.hidesWhenStopped = true;
activityIndicator.activityIndicatorViewStyle = UIActivityIndicatorViewStyle.gray;
view.addSubview(activityIndicator);
activityIndicator.startAnimating();
UIApplication.shared.beginIgnoringInteractionEvents();
}
func stopLoading(){
activityIndicator.stopAnimating();
UIApplication.shared.endIgnoringInteractionEvents();
}
Personally I'm doing this using ngx-material-file-input for the front-end, and Firebase for the back-end. More precisely Cloud Storage for Firebase for the back-end combined with Cloud Firestore. Below an example, which limits file to be not larger than 20 MB, and accepts only certain file extensions. I'm also using Cloud Firestore for storing links to the uploaded files, but you can skip this.

You can try same thing using Joins too..
Using collections.defaultdict
is a big time-saver when you're building dicts and don't know beforehand which keys you're going to have.
Here it's used twice: for the resulting dict, and for each of the values in the dict.
import collections
def aggregate_names(errors):
result = collections.defaultdict(lambda: collections.defaultdict(list))
for real_name, false_name, location in errors:
result[real_name][false_name].append(location)
return result
Combining this with your code:
dictionary = aggregate_names(previousFunction(string))
Or to test:
EXAMPLES = [
('Fred', 'Frad', 123),
('Jim', 'Jam', 100),
('Fred', 'Frod', 200),
('Fred', 'Frad', 300)]
print aggregate_names(EXAMPLES)
Remember, you are NOT allowed to do this.
class foo():
def print_hello(self):
print("Hello") # This next line will produce an ERROR!
self.print_hello() # <---- it calls a class function, inside a class,
# but outside a class function. Not allowed.
You must call a class function from either outside the class, or from within a function in that class.
I have never done so, but it seems like
MATCH (head, head, body) AGAINST ('some words' IN BOOLEAN MODE)
Should give a double weight to matches found in the head.
Just read this comment on the docs page, Thought it might be of value to you:
Posted by Patrick O'Lone on December 9 2002 6:51am
It should be noted in the documentation that IN BOOLEAN MODE will almost always return a relevance of 1.0. In order to get a relevance that is meaningful, you'll need to:
SELECT MATCH('Content') AGAINST ('keyword1 keyword2') as Relevance
FROM table
WHERE MATCH ('Content') AGAINST('+keyword1+keyword2' IN BOOLEAN MODE)
HAVING Relevance > 0.2
ORDER BY Relevance DESC
Notice that you are doing a regular relevance query to obtain relevance factors combined with a WHERE clause that uses BOOLEAN MODE. The BOOLEAN MODE gives you the subset that fulfills the requirements of the BOOLEAN search, the relevance query fulfills the relevance factor, and the HAVING clause (in this case) ensures that the document is relevant to the search (i.e. documents that score less than 0.2 are considered irrelevant). This also allows you to order by relevance.
This may or may not be a bug in the way that IN BOOLEAN MODE operates, although the comments I've read on the mailing list suggest that IN BOOLEAN MODE's relevance ranking is not very complicated, thus lending itself poorly for actually providing relevant documents. BTW - I didn't notice a performance loss for doing this, since it appears MySQL only performs the FULLTEXT search once, even though the two MATCH clauses are different. Use EXPLAIN to prove this.
So it would seem you may not need to worry about calling the fulltext search twice, though you still should "use EXPLAIN to prove this"
Perhaps not in the context that you have it, but you could use
SELECT DISTINCT col1,
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1),
PERCENTILE_CONT(col2) WITHIN GROUP (ORDER BY col2) OVER (PARTITION BY col1, col3),
FROM TableA
You would use this to return different levels of aggregation returned in a single row. The use case would be for when a single grouping would not suffice all of the aggregates needed.
Try get instead for test reasons
<form action="#?name=test" method="GET">
<input type="text" name="firstname" />
<input type="submit" name="submit" value="Submit" />
</form>
and
if(isset($_GET)){
echo $_GET['name'] . '<br>';
echo $_GET['firstname'];
}
Make a surrounding div-tag, and set for it display: grid
in its style attribute.
<div style='display: grid;
text-align: center;
background-color: antiquewhite'
>
<table>
<tr>
<th>Month</th>
<th>Savings</th>
</tr>
<tr>
<td>January</td>
<td>$100</td>
</tr>
<tr>
<td>February</td>
<td>$80</td>
</tr>
</table>
</div>
The text-align property is set only to show, that the text in the regular table cells are affected by it, even though it is set on the surrounding div. The same with the background-color but it is hard to say which element actually holds the background-color.
In case you want to remove elements which are added dynamically try this:
document.body.addEventListener('DOMSubtreeModified', function(event) {
const elements = document.getElementsByClassName('your-class-name');
while (elements.length > 0) elements[0].remove();
});
It does not work because your script in JSFiddle is running inside it's own scope (see the "OnLoad" drop down on the left?).
One way around this is to bind your event handler in javascript (where it should be):
document.getElementById('optionID').onchange = function () {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
Another way is to modify your code for the fiddle environment and explicitly declare your function as global so it can be found by your inline event handler:
window.changeMessage() {
document.getElementById("message").innerHTML = "Having a Baby!!";
};
?
You could use WITH to define your expressions. Then do a simple Sub-SELECT to access those definitions.
CREATE VIEW MyView
AS
WITH MyVars (SomeVar, Var2)
AS (
SELECT
'something' AS 'SomeVar',
123 AS 'Var2'
)
SELECT *
FROM MyTable
WHERE x = (SELECT SomeVar FROM MyVars)
A handle is a sort of pointer in that it is typically a way of referencing some entity.
It would be more accurate to say that a pointer is one type of handle, but not all handles are pointers.
For example, a handle may also be some index into an in memory table, which corresponds to an entry that itself contains a pointer to some object.
The key thing is that when you have a "handle", you neither know nor care how that handle actually ends up identifying the thing that it identifies, all you need to know is that it does.
It should also be obvious that there is no single answer to "what exactly is a handle", because handles to different things, even in the same system, may be implemented in different ways "under the hood". But you shouldn't need to be concerned with those differences.
You can solve the issue by clearing value of address in endpoint tag in web.config:
<endpoint address="" name="wsHttpEndpoint" ....... />
Apparently some POST requests looks like a "GET" to the server (like Heroku...)
So I use this strategy and it works for me:
@RequestMapping(value = "/salvar", method = { RequestMethod.GET, RequestMethod.POST })
For php, when you use checkboxes for multiple values, the name always ends with []. We can use this to make the solution a bit more generic. And, since I put my error message in a data-message-value-missing attribute, I use:
$form.on('change', 'input[type=checkbox][name$="[]"]', e => {
const $inputs = $('input[type=checkbox][name="' + e.target.name + '"]');
const $targetInp = $inputs.filter('[data-message-value-missing]');
if($inputs.filter(':checked').length) {
$targetInp.removeAttr('required');
$form.find('label.error').html('');
} else {
$targetInp.attr('required', 'required');
}
});
To make this work, set the data-message-value-missing and the required on only one (the last) input:
<ul>
<li><input name="BoxSelect[]" type="checkbox" value="Box 1"><label>Box 1</label></li>
<li><input name="BoxSelect[]" type="checkbox" value="Box 2"><label>Box 2</label></li>
<li><input name="BoxSelect[]" type="checkbox" value="Box 3"><label>Box 3</label></li>
<li><input name="BoxSelect[]" type="checkbox" value="Box 4" required data-message-value-missing="Select at least one"><label>Box 4</label></li>
</ul>
I excluded the code to handle the checkValidity(), etc. Seems beyond the scope of this question...
The reason you're getting the unhashable type: 'list'
exception is because k = list[0:j]
sets k
to be a "slice" of the list, which is logically another, often shorter, list. What you need is to get just the first item in list, written like so k = list[0]
. The same for v = list[j + 1:]
which should just be v = list[2]
for the third element of the list returned from the call to readline.split(" ")
.
I noticed several other likely problems with the code, of which I'll mention a few. A big one is you don't want to (re)initialize d
with d = {}
for each line read in the loop. Another is it's generally not a good idea to name variables the same as any of the built-ins types because it'll prevent you from being able to access one of them if you need it — and it's confusing to others who are used to the names designating one of these standard items. For that reason, you ought to rename your variable list
variable something different to avoid issues like that.
Here's a working version of your with these changes in it, I also replaced the if
statement expression you used to check to see if the key was already in the dictionary and now make use of a dictionary's setdefault()
method to accomplish the same thing a little more succinctly.
d = {}
with open("nameerror.txt", "r") as file:
line = file.readline().rstrip()
while line:
lst = line.split() # Split into sequence like ['AAA', 'x', '111'].
k, _, v = lst[:3] # Get first and third items.
d.setdefault(k, []).append(v)
line = file.readline().rstrip()
print('d: {}'.format(d))
Output:
d: {'AAA': ['111', '112'], 'AAC': ['123'], 'AAB': ['111']}
You could try:
<a href="<?php echo $directory ?>">The link to the file</a>
Or for PHP 5.4+ (<?=
is the PHP short echo tag):
<a href="<?= $directory ?>">The link to the file</a>
But your path is relative to the server, don't forget that.
I ran into this as well but I needed control over the rounding type. Thus, I wrote a quick function (see code below) that can take value, rounding type, and desired significant digits into account.
import decimal
from math import log10, floor
def myrounding(value , roundstyle='ROUND_HALF_UP',sig = 3):
roundstyles = [ 'ROUND_05UP','ROUND_DOWN','ROUND_HALF_DOWN','ROUND_HALF_UP','ROUND_CEILING','ROUND_FLOOR','ROUND_HALF_EVEN','ROUND_UP']
power = -1 * floor(log10(abs(value)))
value = '{0:f}'.format(value) #format value to string to prevent float conversion issues
divided = Decimal(value) * (Decimal('10.0')**power)
roundto = Decimal('10.0')**(-sig+1)
if roundstyle not in roundstyles:
print('roundstyle must be in list:', roundstyles) ## Could thrown an exception here if you want.
return_val = decimal.Decimal(divided).quantize(roundto,rounding=roundstyle)*(decimal.Decimal(10.0)**-power)
nozero = ('{0:f}'.format(return_val)).rstrip('0').rstrip('.') # strips out trailing 0 and .
return decimal.Decimal(nozero)
for x in list(map(float, '-1.234 1.2345 0.03 -90.25 90.34543 9123.3 111'.split())):
print (x, 'rounded UP: ',myrounding(x,'ROUND_UP',3))
print (x, 'rounded normal: ',myrounding(x,sig=3))
That's something controlled by your terminal, not by printf
.
printf
simply sends a \t
to the output stream (which can be a tty, a file etc), it doesn't send a number of spaces.
div.abc.xyz {
/* rules go here */
}
... or simply:
.abc.xyz {
/* rules go here */
}
You should try doing it with css3 animation. Check the code bellow:
<!DOCTYPE html>
<html>
<head>
<style>
div {
width: 100px;
height: 100px;
background: red;
position: relative;
-webkit-animation: myfirst 5s infinite; /* Chrome, Safari, Opera */
-webkit-animation-direction: alternate; /* Chrome, Safari, Opera */
animation: myfirst 5s infinite;
animation-direction: alternate;
}
/* Chrome, Safari, Opera */
@-webkit-keyframes myfirst {
0% {background: red; left: 0px; top: 0px;}
25% {background: yellow; left: 200px; top: 0px;}
50% {background: blue; left: 200px; top: 200px;}
75% {background: green; left: 0px; top: 200px;}
100% {background: red; left: 0px; top: 0px;}
}
@keyframes myfirst {
0% {background: red; left: 0px; top: 0px;}
25% {background: yellow; left: 200px; top: 0px;}
50% {background: blue; left: 200px; top: 200px;}
75% {background: green; left: 0px; top: 200px;}
100% {background: red; left: 0px; top: 0px;}
}
</style>
</head>
<body>
<p><strong>Note:</strong> The animation-direction property is not supported in Internet Explorer 9 and earlier versions.</p>
<div></div>
</body>
</html>
Where 'div' is your animated object.
I hope you find this useful.
Thanks.
I have made it working...

On many classes which support both Close()
and Dispose()
methods, the two calls would be equivalent. On some classes, however, it is possible to re-open an object which has been closed. Some such classes may keep some resources alive after a Close, in order to permit reopening; others may not keep any resources alive on Close()
, but might set a flag on Dispose()
to explicitly forbid re-opening.
The contract for IDisposable.Dispose
explicitly requires that calling it on an object which will never be used again will be at worst harmless, so I would recommend calling either IDisposable.Dispose
or a method called Dispose()
on every IDisposable
object, whether or not one also calls Close()
.
The parameter for the JSON.parse may be returning nothing (i.e. the value given for the JSON.parse is undefined
)!
It happened to me while I was parsing the Compiled solidity code from an xyz.sol file.
import web3 from './web3';
import xyz from './build/xyz.json';
const i = new web3.eth.Contract(
JSON.parse(xyz.interface),
'0x99Fd6eFd4257645a34093E657f69150FEFf7CdF5'
);
export default i;
which was misspelled as
JSON.parse(xyz.intereface)
which was returning nothing!
Edit: The original link I answered with is now invalid.The newer URL would be https://developers.google.com/web/tools/chrome-devtools/javascript/add-breakpoints#exceptions as of 2016-11-11.
I realize this question has an answer, but it's no longer accurate. Use the link above ^
(link replaced by edited above) - you can now set it to break on all exceptions or just unhandled ones. (Note that you need to be in the Sources tab to see the button.)
Chrome's also added some other really useful breakpoint capabilities now, such as breaking on DOM changes or network events.
Normally I wouldn't re-answer a question, but I had the same question myself, and I found this now-wrong answer, so I figured I'd put this information in here for people who came along later in searching. :)
Use the target
and lib
compiler options to compile directly to es5
without needing to install the es6-shim
. (Tested with TypeScript 2.1.4
).
In the lib section, use either es2016
or es2015.promise
.
// tsconfig.json
{
"compilerOptions": {
"target": "es5",
"lib": [
"es2015.promise",
"dom"
]
},
"include": [
"src/**/*.ts"
],
"exclude": [
"node_modules"
]
}
Use NPM to install the es6-shim
from the types organization.
npm install @types/es6-shim --save-dev
Before TypeScript 2.0, use typings to install the es6-shim
globally from DefinitelyTyped.
npm install typings --global --save-dev
typings install dt~es6-shim --global --save-dev
The typings
option uses npm
to install typings
globally and then uses typings
to install the shim. The dt~
prefix means to download the shim from DefinitelyTyped. The --global
option means that the shim's types will be available throughout the project.

The div
tag is a block element, causing that behavior.
You should use a span
element instead, which is inline.
If you really want to use div
, add style="display: inline"
. (You can also put that in a CSS rule)
NUnit is probably the most supported by the 3rd party tools. It's also been around longer than the other three.
I personally don't care much about unit test frameworks, mocking libraries are IMHO much more important (and lock you in much more). Just pick one and stick with it.
If you are having this issue and you are performing a populate somewhere along the lines, see this Mongoose issue.
Update to Mongoose 4.0 and the issue has been fixed.
You don't have to, but some people like to explicitly initialize all variables (I do too). Especially those who program in a variety of languages, it's just easier to have the rule of always initializing your variables rather than deciding case-by-case/language-by-language.
For instance Java has default values for Boolean, int etc .. C on the other hand doesn't automatically give initial values, whatever happens to be in memory is what you end up with unless you assign a value explicitly yourself.
In your case above, as you discovered, the code works just as well without the initialization, esp since the variable is set in the next line which makes it appear particularly redundant. Sometimes you can combine both of those lines (declaration and initialization - as shown in some of the other posts) and get the best of both approaches, i.e., initialize the your variable with the result of the email1.equals (email2);
operation.
Apart from the other answers, that considered the connection string itself, it might simply be necessary to download the correct odbc driver. My client just faced this issue when executing a python app, that required it. you can check this by pressing windows + typing "odbc". the correct driver should appear in the drivers tab.
You'd have to add a data attribute to the rows called data-gender
with a male
or female
value and use the attribute selector:
HTML:
<td data-gender="male">...</td>
CSS:
td[data-gender="male"] { ... }
>>> print sorted(d.keys())
['a', 'b', 'c']
Use the sorted function, which sorts the iterable passed in.
The .keys()
method returns the keys in an arbitrary order.
Note, while the above answers are correct, if you want, you can do something like:
alert("The variable named x1 has value: " + x1);
Assembly is not portable between different microprocessors.
Another project to have a look at: http://readthedocs.org/docs/django-private-files/en/latest/usage.html Looks promissing, haven't tested it myself yet tho.
Basically the project abstracts the mod_xsendfile configuration and allows you to do things like:
from django.db import models
from django.contrib.auth.models import User
from private_files import PrivateFileField
def is_owner(request, instance):
return (not request.user.is_anonymous()) and request.user.is_authenticated and
instance.owner.pk = request.user.pk
class FileSubmission(models.Model):
description = models.CharField("description", max_length = 200)
owner = models.ForeignKey(User)
uploaded_file = PrivateFileField("file", upload_to = 'uploads', condition = is_owner)
The reason it is not working is because javascript strings must be terminated before the next newline character (not a \n
obviously). The reason \n
exists is to allow developers an easy way to put the newline character (ASCII: 10) into their strings.
When you have a string which looks like this:
//Note lack of terminating double quote
var foo = "Bob
Your code will have a syntax error at that point and cease to run.
If you wish to have a string which spans multiple lines, you may insert a backslash character '\
' just before you terminate the line, like so:
//Perfectly valid code
var foo = "Bob \
is \
cool.";
However that string will not contain \n
characters in the positions where the string was broken into separate lines. The only way to insert a newline into a string is to insert a character with a value of 10, the easiest way of which is the \n
escape character.
var foo = "Bob\nis\ncool.";
The Java Language Specification, section 15.10, states:
An array creation expression creates an object that is a new array whose elements are of the type specified by the PrimitiveType or ClassOrInterfaceType. It is a compile-time error if the ClassOrInterfaceType does not denote a reifiable type (§4.7).
and
The rules above imply that the element type in an array creation expression cannot be a parameterized type, other than an unbounded wildcard.
The closest you can do is use an unchecked cast, either from the raw type, as you have done, or from an unbounded wildcard:
HashMap<String, String>[] responseArray = (Map<String, String>[]) new HashMap<?,?>[games.size()];
Your version is clearly better :-)
window.location.href
returns the location of the current page.
top.location.href
(which is an alias of window.top.location.href
) returns the location of the topmost window in the window hierarchy. If a window has no parent, top
is a reference to itself (in other words, window
=== window.top
).
top
is useful both when you're dealing with frames and when dealing with windows which have been opened by other pages. For example, if you have a page called test.html
with the following script:
var newWin=window.open('about:blank','test','width=100,height=100');
newWin.document.write('<script>alert(top.location.href);</script>');
The resulting alert will have the full path to test.html – not about:blank, which is what window.location.href
would return.
To answer your question about redirecting, go with window.location.assign(url);
To do this using Python code:
importlib.metadata.version
import importlib.metadata
importlib.metadata.version('beautifulsoup4')
'4.9.1'
(using importlib_metadata.version
)
!pip install importlib-metadata
import importlib_metadata
importlib_metadata.version('beautifulsoup4')
'4.9.1'
pkg_resources.Distribution
import pkg_resources
pkg_resources.get_distribution('beautifulsoup4').version
'4.9.1'
pkg_resources.get_distribution('beautifulsoup4').parsed_version
<Version('4.9.1')>

@Drew Baker gave a great solution to solve the problem. The code works properly. However, those who uses AngularJs may find lots of dependency on jQuery. Consequently, I thought it is a good idea to paste for AngularJS users, a code following @Drew Baker's solution.
AngularJs way of the same code
1. Html: use the bellow tag in you html file:
<svg-image src="/icons/my.svg" class="any-class-you-wish"></svg-image>
2. Directive: this will be the directive that you will need to recognise the tag:
'use strict';
angular.module('myApp')
.directive('svgImage', ['$http', function($http) {
return {
restrict: 'E',
link: function(scope, element) {
var imgURL = element.attr('src');
// if you want to use ng-include, then
// instead of the above line write the bellow:
// var imgURL = element.attr('ng-include');
var request = $http.get(
imgURL,
{'Content-Type': 'application/xml'}
);
scope.manipulateImgNode = function(data, elem){
var $svg = angular.element(data)[4];
var imgClass = elem.attr('class');
if(typeof(imgClass) !== 'undefined') {
var classes = imgClass.split(' ');
for(var i = 0; i < classes.length; ++i){
$svg.classList.add(classes[i]);
}
}
$svg.removeAttribute('xmlns:a');
return $svg;
};
request.success(function(data){
element.replaceWith(scope.manipulateImgNode(data, element));
});
}
};
}]);
3. CSS:
.any-class-you-wish{
border: 1px solid red;
height: 300px;
width: 120px
}
4. Unit-test with karma-jasmine:
'use strict';
describe('Directive: svgImage', function() {
var $rootScope, $compile, element, scope, $httpBackend, apiUrl, data;
beforeEach(function() {
module('myApp');
inject(function($injector) {
$rootScope = $injector.get('$rootScope');
$compile = $injector.get('$compile');
$httpBackend = $injector.get('$httpBackend');
apiUrl = $injector.get('apiUrl');
});
scope = $rootScope.$new();
element = angular.element('<svg-image src="/icons/icon-man.svg" class="svg"></svg-image>');
element = $compile(element)(scope);
spyOn(scope, 'manipulateImgNode').andCallThrough();
$httpBackend.whenGET(apiUrl + 'me').respond(200, {});
data = '<?xml version="1.0" encoding="utf-8"?>' +
'<!-- Generator: Adobe Illustrator 17.0.0, SVG Export Plug-In . SVG Version: 6.00 Build 0) -->' +
'<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">' +
'<!-- Obj -->' +
'<!-- Obj -->' +
'<svg version="1.1" id="Capa_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"' +

'<g>' +
'<path fill="#F4A902" d=""/>' +
'<path fill="#F4A902" d=""/>' +
'</g>' +
'</svg>';
$httpBackend.expectGET('/icons/icon-man.svg').respond(200, data);
});
afterEach(function() {
$httpBackend.verifyNoOutstandingExpectation();
$httpBackend.verifyNoOutstandingRequest();
});
it('should call manipulateImgNode atleast once', function () {
$httpBackend.flush();
expect(scope.manipulateImgNode.callCount).toBe(1);
});
it('should return correct result', function () {
$httpBackend.flush();
var result = scope.manipulateImgNode(data, element);
expect(result).toBeDefined();
});
it('should define classes', function () {
$httpBackend.flush();
var result = scope.manipulateImgNode(data, element);
var classList = ["svg"];
expect(result.classList[0]).toBe(classList[0]);
});
});
If you just want to remove it from the existing array and not create a new one, try:
var items = [{Id: 1},{Id: 2},{Id: 3}];
items.splice(_.indexOf(items, _.find(items, function (item) { return item.Id === 2; })), 1);
If you prefer separation of concerns such that logic for adding and removing classes happens on the controller, you can do this
controller
(function() {
angular.module('MyApp', []).controller('MyController', MyController);
function MyController() {
var vm = this;
vm.tab = 0;
vm.setTab = function(val) {
vm.tab = val;
};
vm.toggleClass = function(val) {
return val === vm.tab;
};
}
})();
HTML
<div ng-app="MyApp">
<ul class="" ng-controller="MyController as myCtrl">
<li ng-click="myCtrl.setTab(0)" ng-class="{'highlighted':myCtrl.toggleClass(0)}">One</li>
<li ng-click="myCtrl.setTab(1)" ng-class="{'highlighted':myCtrl.toggleClass(1)}">Two</li>
<li ng-click="myCtrl.setTab(2)" ng-class="{'highlighted':myCtrl.toggleClass(2)}">Three</li>
<li ng-click="myCtrl.setTab(3)" ng-class="{'highlighted':myCtrl.toggleClass(3)}">Four</li>
</ul>
CSS
.highlighted {
background-color: green;
color: white;
}
in my case, the problem got solved only by implementing serializable as below:
@Entity @Table(name = "User" , uniqueConstraints = { @UniqueConstraint(columnNames = {"nam"}) }) public class User extends GenericT implements Serializable
It supports after KITKAT. Just add following code inside onCreate method of your Activity. No need any modifications to Manifest file.
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
Window w = getWindow(); // in Activity's onCreate() for instance
w.setFlags(WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS, WindowManager.LayoutParams.FLAG_LAYOUT_NO_LIMITS);
}
Because QuerySets implement the Python __or__
operator (|
), or union, it just works. As you'd expect, the |
binary operator returns a QuerySet
so order_by()
, .distinct()
, and other queryset filters can be tacked on to the end.
combined_queryset = User.objects.filter(income__gte=5000) | User.objects.filter(income__isnull=True)
ordered_queryset = combined_queryset.order_by('-income')
Update 2019-06-20: This is now fully documented in the Django 2.1 QuerySet API reference. More historic discussion can be found in DjangoProject ticket #21333.
In .NET Core WebAPI (version 3.0 and above):
var requestUrl = $"{Request.Scheme}://{Request.Host.Value}/";
Following method is a generic way of pushing an Android Studio project to a GIT based repository solely using GUI.This has been tested with a GIT repository hosted in Visual Studio Online and should virtually work with GitHub or any other GIT based version control provider.
Note: If you are using GitHub 'Share on GitHub' is the easiest option as stated in other answers.
Enable Version Control Integration for The Project
VCS (main menu) >> Enable Version Control Integration >> Select GIT
Commit Added Files
Open the Version Control windows (Next to terminal window) >> Click commit button
In the prompt window select "commit and push"
Defining Remote
After analyzing code android studio will prompt to review or commit code when committed will be prompt to define the remote repository.There you can add the url to GIT repository.
Then enter the credentials for the repository and click 'Ok'.(Visual Studio online Users need to enable "alternate authentication credentials" as mentioned here to login to repository)
1 Step - Install a required extension
sudo apt-get install libz-dev -y
2 Step - Install the PHP extension
pecl install zlib zip
3 Step - Restart your Apache
sudo /etc/init.d/apache2 restart
If does not work you can check if the zip.ini is called in your phpinfo, to check if the zip.so was included.
You can do it like this:
In your main view controller:
func showModal() {
let modalViewController = ModalViewController()
modalViewController.modalPresentationStyle = .overCurrentContext
presentViewController(modalViewController, animated: true, completion: nil)
}
In your modal view controller:
class ModalViewController: UIViewController {
override func viewDidLoad() {
view.backgroundColor = UIColor.clearColor()
view.opaque = false
}
}
If you are working with a storyboard:
Just add a Storyboard Segue with Kind
set to Present Modally
to your modal view controller and on this view controller set the following values:
As Crashalot pointed out in his comment: Make sure the segue only uses Default
for both Presentation
and Transition
. Using Current Context
for Presentation
makes the modal turn black instead of remaining transparent.
for the entire line
^(\w+)\s+(\w+)\s+(\d+(?:\/\d+){2})\s+(\w+)$
The correct one for me is the Zuan solution. Be aware to add isset to $args->add_li_class
, however you got Notice: Undefined property: stdClass::$add_li_class
if you haven't set the property in all yours wp_nav_menu()
functions.
This is the function that worked for me:
function add_additional_class_on_li($classes, $item, $args) {
if(isset($args->add_li_class)) {
$classes[] = $args->add_li_class;
}
return $classes;
}
add_filter('nav_menu_css_class', 'add_additional_class_on_li', 1, 3);
You could use javax.servlet.Filter
if there wasn't a requirement to log java method that been executed.
But with this requirement you have to access information stored in handlerMapping
of DispatcherServlet
. That said, you can override DispatcherServlet
to accomplish logging of request/response pair.
Below is an example of idea that can be further enhanced and adopted to your needs.
public class LoggableDispatcherServlet extends DispatcherServlet {
private final Log logger = LogFactory.getLog(getClass());
@Override
protected void doDispatch(HttpServletRequest request, HttpServletResponse response) throws Exception {
if (!(request instanceof ContentCachingRequestWrapper)) {
request = new ContentCachingRequestWrapper(request);
}
if (!(response instanceof ContentCachingResponseWrapper)) {
response = new ContentCachingResponseWrapper(response);
}
HandlerExecutionChain handler = getHandler(request);
try {
super.doDispatch(request, response);
} finally {
log(request, response, handler);
updateResponse(response);
}
}
private void log(HttpServletRequest requestToCache, HttpServletResponse responseToCache, HandlerExecutionChain handler) {
LogMessage log = new LogMessage();
log.setHttpStatus(responseToCache.getStatus());
log.setHttpMethod(requestToCache.getMethod());
log.setPath(requestToCache.getRequestURI());
log.setClientIp(requestToCache.getRemoteAddr());
log.setJavaMethod(handler.toString());
log.setResponse(getResponsePayload(responseToCache));
logger.info(log);
}
private String getResponsePayload(HttpServletResponse response) {
ContentCachingResponseWrapper wrapper = WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
if (wrapper != null) {
byte[] buf = wrapper.getContentAsByteArray();
if (buf.length > 0) {
int length = Math.min(buf.length, 5120);
try {
return new String(buf, 0, length, wrapper.getCharacterEncoding());
}
catch (UnsupportedEncodingException ex) {
// NOOP
}
}
}
return "[unknown]";
}
private void updateResponse(HttpServletResponse response) throws IOException {
ContentCachingResponseWrapper responseWrapper =
WebUtils.getNativeResponse(response, ContentCachingResponseWrapper.class);
responseWrapper.copyBodyToResponse();
}
}
HandlerExecutionChain
- contains the information about request handler.
You then can register this dispatcher as following:
@Bean
public ServletRegistrationBean dispatcherRegistration() {
return new ServletRegistrationBean(dispatcherServlet());
}
@Bean(name = DispatcherServletAutoConfiguration.DEFAULT_DISPATCHER_SERVLET_BEAN_NAME)
public DispatcherServlet dispatcherServlet() {
return new LoggableDispatcherServlet();
}
And here's the sample of logs:
http http://localhost:8090/settings/test
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=500, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475814077,"status":500,"error":"Internal Server Error","exception":"java.lang.RuntimeException","message":"org.springframework.web.util.NestedServletException: Request processing failed; nested exception is java.lang.RuntimeException","path":"/settings/test"}'}
http http://localhost:8090/settings/params
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=200, path='/settings/httpParams', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public x.y.z.DTO x.y.z.Controller.params()] and 3 interceptors', arguments=null, response='{}'}
http http://localhost:8090/123
i.g.m.s.s.LoggableDispatcherServlet : LogMessage{httpStatus=404, path='/error', httpMethod='GET', clientIp='127.0.0.1', javaMethod='HandlerExecutionChain with handler [public org.springframework.http.ResponseEntity<java.util.Map<java.lang.String, java.lang.Object>> org.springframework.boot.autoconfigure.web.BasicErrorController.error(javax.servlet.http.HttpServletRequest)] and 3 interceptors', arguments=null, response='{"timestamp":1472475840592,"status":404,"error":"Not Found","message":"Not Found","path":"/123"}'}
UPDATE
In case of errors Spring does automatic error handling. Therefore, BasicErrorController#error
is shown as request handler. If you want to preserve original request handler, then you can override this behavior at spring-webmvc-4.2.5.RELEASE-sources.jar!/org/springframework/web/servlet/DispatcherServlet.java:971
before #processDispatchResult
is called, to cache original handler.
Your code makes no sense, maybe because it's out of context.
If you mean code like this:
$('a').click(function () {
callFunction();
return false;
});
The return false will return false to the click-event. That tells the browser to stop following events, like follow a link. It has nothing to do with the previous function call. Javascript runs from top to bottom more or less, so a line cannot affect a previous line.
If a method on a module is turned into a module function you can simply call it off of Mods as if it had been declared as
module Mods
def self.foo
puts "Mods.foo(self)"
end
end
The module_function approach below will avoid breaking any classes which include all of Mods.
module Mods
def foo
puts "Mods.foo"
end
end
class Includer
include Mods
end
Includer.new.foo
Mods.module_eval do
module_function(:foo)
public :foo
end
Includer.new.foo # this would break without public :foo above
class Thing
def bar
Mods.foo
end
end
Thing.new.bar
However, I'm curious why a set of unrelated functions are all contained within the same module in the first place?
Edited to show that includes still work if public :foo
is called after module_function :foo
I know its been a while since the question was asked but I was able to find a solution:
int sockfd;
int option = 1;
sockfd = socket(AF_INET, SOCK_STREAM, 0);
setsockopt(sockfd, SOL_SOCKET, SO_REUSEADDR, &option, sizeof(option));
This set the socket able to be reused immediately.
I apologize if this is "wrong". I'm not very experienced with sockets
Not a direct answer to the question, but this may help those who are having trouble creating style
information using Typescript.
I was getting an error telling me that the following was incorrect:
let iconStyle = {
position: 'relative',
maxHeight: '90px',
top: '25%',
}
The error told me that "types of property 'position' are incompatible". I have no idea why.
I fixed this by adding a strict Typescript declaration, like so:
let iconStyle: CSSProperties = {
position: 'relative',
maxHeight: '90px',
top: '25%',
}
This works.
You need to create a function, but it is for your own convenience. It works perfect and I never encountered any faulty computations using this function.
CREATE FUNCTION [dbo].[get_days](@date datetime)
RETURNS int
AS
BEGIN
SET @date = DATEADD(MONTH, 1, @date)
DECLARE @result int = (select DAY(DATEADD(DAY, -DAY(@date), @date)))
RETURN @result
END
How it works: subtracting the date's day number from the date itself gives you the last day of previous month. So, you need to add one month to the given date, subtract the day number and get the day component of the result.
This is a vbscript implementation of merge sort.
'@Function Name: Sort
'@Author: Lewis Gordon
'@Creation Date: 4/26/12
'@Description: Sorts a given array either in ascending or descending order, as specified by the
' order parameter. This array is then returned at the end of the function.
'@Prerequisites: An array must be allocated and have all its values inputted.
'@Parameters:
' $ArrayToSort: This is the array that is being sorted.
' $Order: This is the sorting order that the array will be sorted in. This parameter
' can either be "ASC" or "DESC" or ascending and descending, respectively.
'@Notes: This uses merge sort under the hood. Also, this function has only been tested for
' integers and strings in the array. However, this should work for any data type that
' implements the greater than and less than comparators. This function also requires
' that the merge function is also present, as it is needed to complete the sort.
'@Examples:
' Dim i
' Dim TestArray(50)
' Randomize
' For i=0 to UBound(TestArray)
' TestArray(i) = Int((100 - 0 + 1) * Rnd + 0)
' Next
' MsgBox Join(Sort(TestArray, "DESC"))

By using ToDictionary
:
var dictionary = list.ToDictionary(s => s);
If it is possible that any string could be repeated, either do a Distinct
call first on the list (to remove duplicates), or use ToLookup
which allows for multiple values per key.
Is it good to use async action everywhere in ASP.NET MVC?
It's good to do so wherever you can use an async method especially when you have performance issues at the worker process level which happens for massive data and calculation operations. Otherwise, no need because unit testing will need casting.
Regarding awaitable methods: shall I use async/await keywords when I want to query a database (via EF/NHibernate/other ORM)?
Yes, it's better to use async for any DB operation as could as possible to avoid performance issues at the level of worker processes. Note that EF has created many async alternatives for most operations, such as:
.ToListAsync()
.FirstOrDefaultAsync()
.SaveChangesAsync()
.FindAsync()
How many times can I use await keywords to query the database asynchronously in one single action method?
The sky is the limit
I have read all answers, but this link was more clear explanation for me about difference between CPU(Processor) and Core. So I'm leaving here some notes from there.
The main difference between CPU and Core is that the CPU is an electronic circuit inside the computer that carries out instruction to perform arithmetic, logical, control and input/output operations while the core is an execution unit inside the CPU that receives and executes instructions.
If you need "sub-10-character hash"
you could use Fletcher-32 algorithm which produces 8 character hash (32 bits), CRC-32 or Adler-32.
CRC-32 is slower than Adler32 by a factor of 20% - 100%.
Fletcher-32 is slightly more reliable than Adler-32. It has a lower computational cost than the Adler checksum: Fletcher vs Adler comparison.
A sample program with a few Fletcher implementations is given below:
#include <stdio.h>
#include <string.h>
#include <stdint.h> // for uint32_t
uint32_t fletcher32_1(const uint16_t *data, size_t len)
{
uint32_t c0, c1;
unsigned int i;
for (c0 = c1 = 0; len >= 360; len -= 360) {
for (i = 0; i < 360; ++i) {
c0 = c0 + *data++;
c1 = c1 + c0;
}
c0 = c0 % 65535;
c1 = c1 % 65535;
}
for (i = 0; i < len; ++i) {
c0 = c0 + *data++;
c1 = c1 + c0;
}
c0 = c0 % 65535;
c1 = c1 % 65535;
return (c1 << 16 | c0);
}
uint32_t fletcher32_2(const uint16_t *data, size_t l)
{
uint32_t sum1 = 0xffff, sum2 = 0xffff;
while (l) {
unsigned tlen = l > 359 ? 359 : l;
l -= tlen;
do {
sum2 += sum1 += *data++;
} while (--tlen);
sum1 = (sum1 & 0xffff) + (sum1 >> 16);
sum2 = (sum2 & 0xffff) + (sum2 >> 16);
}
/* Second reduction step to reduce sums to 16 bits */
sum1 = (sum1 & 0xffff) + (sum1 >> 16);
sum2 = (sum2 & 0xffff) + (sum2 >> 16);
return (sum2 << 16) | sum1;
}
int main()
{
char *str1 = "abcde";
char *str2 = "abcdef";
size_t len1 = (strlen(str1)+1) / 2; // '\0' will be used for padding
size_t len2 = (strlen(str2)+1) / 2; //
uint32_t f1 = fletcher32_1(str1, len1);
uint32_t f2 = fletcher32_2(str1, len1);
printf("%u %X \n", f1,f1);
printf("%u %X \n\n", f2,f2);
f1 = fletcher32_1(str2, len2);
f2 = fletcher32_2(str2, len2);
printf("%u %X \n",f1,f1);
printf("%u %X \n",f2,f2);
return 0;
}
Output:
4031760169 F04FC729
4031760169 F04FC729
1448095018 56502D2A
1448095018 56502D2A
Agrees with Test vectors:
"abcde" -> 4031760169 (0xF04FC729)
"abcdef" -> 1448095018 (0x56502D2A)
Adler-32 has a weakness for short messages with few hundred bytes, because the checksums for these messages have a poor coverage of the 32 available bits. Check this:
The Adler32 algorithm is not complex enough to compete with comparable checksums.
webRequest.ContentType = "application/x-www-form-urlencoded";
Where does application/x-www-form-urlencoded's name come from?
If you send HTTP GET request, you can use query parameters as follows:
http://example.com/path/to/page
?name=ferret&color=purple
The content of the fields is encoded as a query string. The application/x-www-form-
urlencoded
's name come from the previous url query parameter but the query parameters is
in where the body of request instead of url.
The whole form data is sent as a long query string.The query string contains name- value pairs separated by & character
e.g. field1=value1&field2=value2
It can be simple request called simple - don't trigger a preflight check
Simple request must have some properties. You can look here for more info. One of them is that there are only three values allowed for Content-Type header for simple requests
3.For mostly flat param trees, application/x-www-form-urlencoded is tried and tested.
request.ContentType = "application/json; charset=utf-8";
axios and superagent, two of the more popular npm HTTP libraries, work with JSON bodies by default.
{ "id": 1, "name": "Foo", "price": 123, "tags": [ "Bar", "Eek" ], "stock": { "warehouse": 300, "retail": 20 } }
Now, if the request isn't simple request, the browser automatically sends a HTTP request before the original one by OPTIONS method to check whether it is safe to send the original request. If itis ok, Then send actual request. You can look here for more info.
After upgrading from 4.6.1 framework to 4.7.2 we started getting this error:
"The type 'System.Object' is defined in an assembly that is not referenced. You must add a reference to assembly 'netstandard, Version=2.0.0.0, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51'." and ultimately the solution was to add the "netstandard" assembly reference mentioned above:
<compilation debug="true" targetFramework="4.7.1" >
<assemblies>
<add assembly="netstandard, Version=2.0.0.0, Culture=neutral,
PublicKeyToken=cc7b13ffcd2ddd51"/>
</assemblies>
</compilation>
To get a list of the words that appear more than once together with how often they occur, use a combination of GROUP BY and HAVING:
SELECT word, COUNT(*) AS cnt
FROM words
GROUP BY word
HAVING cnt > 1
To find the number of words in the above result set, use that as a subquery and count the rows in an outer query:
SELECT COUNT(*)
FROM
(
SELECT NULL
FROM words
GROUP BY word
HAVING COUNT(*) > 1
) T1
Putting the various suggestions together, the cleanest version I was able to come up with (without unreliable grep which triggers parts of words) is:
kill -0 $(pidof mysql) 2> /dev/null || echo "Mysql ain't runnin' message/actions"
kill -0 doesn't kill the process but checks if it exists and then returns true, if you don't have pidof on your system, store the pid when you launch the process:
$ mysql &
$ echo $! > pid_stored
then in the script:
kill -0 $(cat pid_stored) 2> /dev/null || echo "Mysql ain't runnin' message/actions"
When i tried the solution with /XD i found, that the path to exclude should be the source path - not the destination.
e.g. this Works
robocopy c:\test\a c:\test\b /MIR /XD c:\test\a\leavethisdiralone\
Are you looking for the following plot:
library(ggplot2)
l<-df[df$ID %in% c("P1","P3"),]
myplot<-ggplot(l)+geom_line(aes(Value1, Value2, group=ID, colour=ID))
The standard way is to make them "setuid" so that they start up as root, and then they throw away that root privilege as soon as they've bound to the port but before they start accepting connections to it. You can see good examples of that in the source code for Apache and INN. I'm told that Lighttpd is another good example.
Another example is Postfix, which uses multiple daemons that communicate through pipes, and only one or two of them (which do very little except accept or emit bytes) run as root and the rest run at a lower privilege.
# short and sweet with O(n) table memory
#include <iostream>
#include <vector>
int count( std::vector<int> s, int n )
{
std::vector<int> table(n+1,0);
table[0] = 1;
for ( auto& k : s )
for(int j=k; j<=n; ++j)
table[j] += table[j-k];
return table[n];
}
int main()
{
std::cout << count({25, 10, 5, 1}, 100) << std::endl;
return 0;
}
my 2cents would be to use json.MarshalIndent
-- surprised this isn't suggested, as it is the most straightforward. for example:
func prettyPrint(i interface{}) string {
s, _ := json.MarshalIndent(i, "", "\t")
return string(s)
}
no external deps and results in nicely formatted output.
You can use $http.get()
method to fetch your JSON
file. Then assign response data to a $scope
object. In HTML
to create table use ng-repeat for $scope object. ng-repeat
will loop the rows in-side this loop you can bind data to columns dynamically.
I have checked your code and you have created static table
<table>
<tr>
<th>Name</th>
<th>Relationship</th>
</tr>
<tr ng-repeat="indivisual in members">
<td>{{ indivisual.Name }}</td>
<td>{{ indivisual.Relation }}</td>
</tr>
</table>
so better your can go to my code to create dynamic table as per data you column and row will be increase or decrease..
You can use the required
html attribute if you want:
@Html.TextBoxFor(m => m.ShortName,
new { @class = "form-control", placeholder = "short name", required="required"})
or you can use the RequiredAttribute class in .Net. With jQuery the RequiredAttribute
can Validate on the front end and server side. If you want to go the MVC route, I'd suggest reading Data annotations MVC3 Required attribute.
OR
You can get really advanced:
@{
// if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
var attributes = new Dictionary<string, object>(
Html.GetUnobtrusiveValidationAttributes(ViewData.TemplateInfo.HtmlFieldPrefix));
attributes.Add("class", "form-control");
attributes.Add("placeholder", "short name");
if (ViewData.ModelMetadata.ContainerType
.GetProperty(ViewData.ModelMetadata.PropertyName)
.GetCustomAttributes(typeof(RequiredAttribute), true)
.Select(a => a as RequiredAttribute)
.Any(a => a != null))
{
attributes.Add("required", "required");
}
@Html.TextBoxFor(m => m.ShortName, attributes)
}
or if you need it for multiple editor templates:
public static class ViewPageExtensions
{
public static IDictionary<string, object> GetAttributes(this WebViewPage instance)
{
// if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
var attributes = new Dictionary<string, object>(
instance.Html.GetUnobtrusiveValidationAttributes(
instance.ViewData.TemplateInfo.HtmlFieldPrefix));
if (ViewData.ModelMetadata.ContainerType
.GetProperty(ViewData.ModelMetadata.PropertyName)
.GetCustomAttributes(typeof(RequiredAttribute), true)
.Select(a => a as RequiredAttribute)
.Any(a => a != null))
{
attributes.Add("required", "required");
}
}
}
then in your templates:
@{
// if you aren't using UnobtrusiveValidation, don't pass anything to this constructor
var attributes = this.GetAttributes();
attributes.Add("class", "form-control");
attributes.Add("placeholder", "short name");
@Html.TextBoxFor(m => m.ShortName, attributes)
}
Update 1 (for Tomas who is unfamilar with ViewData).
What's the difference between ViewData and ViewBag?
Excerpt:
So basically it (ViewBag) replaces magic strings:
ViewData["Foo"]
with magic properties:
ViewBag.Foo
os.environ
behaves like a python dictionary, so all the common dictionary operations can be performed. In addition to the get
and set
operations mentioned in the other answers, we can also simply check if a key exists. The keys and values should be stored as strings.
Python 3
For python 3, dictionaries use the in keyword instead of has_key
>>> import os
>>> 'HOME' in os.environ # Check an existing env. variable
True
...
Python 2
>>> import os
>>> os.environ.has_key('HOME') # Check an existing env. variable
True
>>> os.environ.has_key('FOO') # Check for a non existing variable
False
>>> os.environ['FOO'] = '1' # Set a new env. variable (String value)
>>> os.environ.has_key('FOO')
True
>>> os.environ.get('FOO') # Retrieve the value
'1'
There is one important thing to note about using os.environ
:
Although child processes inherit the environment from the parent process, I had run into an issue recently and figured out, if you have other scripts updating the environment while your python script is running, calling os.environ
again will not reflect the latest values.
Excerpt from the docs:
This mapping is captured the first time the os module is imported, typically during Python startup as part of processing site.py. Changes to the environment made after this time are not reflected in os.environ, except for changes made by modifying os.environ directly.
os.environ.data
which stores all the environment variables, is a dict object, which contains all the environment values:
>>> type(os.environ.data) # changed to _data since v3.2 (refer comment below)
<type 'dict'>
Write your own method, and use it everywhere you want a number value:
function getNum(val) {
if (isNaN(val)) {
return 0;
}
return val;
}
Here's my recipe:
Create a static HTML that redirects to your requested app URL, put that page on the web.
That way, the links you share are 'real' links as far as Android is concerned ( they will be 'clickable').
You 'share' a regular HTTP link, www.your.server.com/foo/bar.html This URL returns a simple 8 line HTML that redirects to your app's URI (window.location = "blah://kuku") (note that 'blah' doesn't have to be HTTP or HTTPS any more).
Once you get this up and running, you can augment the HTML with all the fancy capabilities as suggested above.
This works with the built-in browser, Opera, and Firefox (haven't tested any other browser). Firefox asks 'This link needs to be opened with an application' (ok, cancel). Other browsers apparently don't worry about security that much, they just open the app, no questions asked.
This should work:
cat "$API" >> "$CONFIG"
You need to use the >>
operator to append to a file. Redirecting with >
causes the file to be overwritten. (truncated).
Try using the onbeforeunload property, which will let the user choose whether he wants to navigate away from the page.
Example: https://developer.mozilla.org/en-US/docs/Web/API/Window.onbeforeunload
In HTML5 you can use sandbox property. Please see Pankrat's answer below. http://www.html5rocks.com/en/tutorials/security/sandboxed-iframes/
Opening XCode and accepting the license fixes the issue.
PowerShell 3 has the $PSScriptRoot
automatic variable:
Contains the directory from which a script is being run.
In Windows PowerShell 2.0, this variable is valid only in script modules (.psm1). Beginning in Windows PowerShell 3.0, it is valid in all scripts.
Don't be fooled by the poor wording. PSScriptRoot
is the directory of the current file.
In PowerShell 2, you can calculate the value of $PSScriptRoot
yourself:
# PowerShell v2
$PSScriptRoot = Split-Path -Parent -Path $MyInvocation.MyCommand.Definition
The best way to extract the values is to just do the following
json.loads(dataframe[column].value_counts().to_json())
This returns a dictionary which you can use like any other dict. Using values or keys.
{"apple": 5, "sausage": 2, "banana": 2, "cheese": 1}
There are a several ways of declaring variables in SQL*Plus scripts.
The first is to use VAR, to declare a bind variable. The mechanism for assigning values to a VAR is with an EXEC call:
SQL> var name varchar2(20)
SQL> exec :name := 'SALES'
PL/SQL procedure successfully completed.
SQL> select * from dept
2 where dname = :name
3 /
DEPTNO DNAME LOC
---------- -------------- -------------
30 SALES CHICAGO
SQL>
A VAR is particularly useful when we want to call a stored procedure which has OUT parameters or a function.
Alternatively we can use substitution variables. These are good for interactive mode:
SQL> accept p_dno prompt "Please enter Department number: " default 10
Please enter Department number: 20
SQL> select ename, sal
2 from emp
3 where deptno = &p_dno
4 /
old 3: where deptno = &p_dno
new 3: where deptno = 20
ENAME SAL
---------- ----------
CLARKE 800
ROBERTSON 2975
RIGBY 3000
KULASH 1100
GASPAROTTO 3000
SQL>
When we're writing a script which calls other scripts it can be useful to DEFine the variables upfront. This snippet runs without prompting me to enter a value:
SQL> def p_dno = 40
SQL> select ename, sal
2 from emp
3 where deptno = &p_dno
4 /
old 3: where deptno = &p_dno
new 3: where deptno = 40
no rows selected
SQL>
Finally there's the anonymous PL/SQL block. As you see, we can still assign values to declared variables interactively:
SQL> set serveroutput on size unlimited
SQL> declare
2 n pls_integer;
3 l_sal number := 3500;
4 l_dno number := &dno;
5 begin
6 select count(*)
7 into n
8 from emp
9 where sal > l_sal
10 and deptno = l_dno;
11 dbms_output.put_line('top earners = '||to_char(n));
12 end;
13 /
Enter value for dno: 10
old 4: l_dno number := &dno;
new 4: l_dno number := 10;
top earners = 1
PL/SQL procedure successfully completed.

@toivotuo 's method worked best and most reliably for me under python3. My goal was to identify gzipped files which do not have a reliable .gz extension. I installed python3-magic.
import magic
filename = "./datasets/test"
def file_mime_type(filename):
m = magic.open(magic.MAGIC_MIME)
m.load()
return(m.file(filename))
print(file_mime_type(filename))
for a gzipped file it returns: application/gzip; charset=binary
for an unzipped txt file (iostat data): text/plain; charset=us-ascii
for a tar file: application/x-tar; charset=binary
for a bz2 file: application/x-bzip2; charset=binary
and last but not least for me a .zip file: application/zip; charset=binary
You don't need to - if the favicon is place in the root at favicon.ico, browsers will automatically pick it up.
If you don't see it working, clear your cache etc, it does work without the markup. You only need to use the code if you want to call it something else, or put it on a CDN for instance.
I use this alias in .profile
:
alias qclean="rabbitmqctl list_queues | python ~/bin/qclean.py"
where qclean.py
has the following code:
import sys
import pika
connection = pika.BlockingConnection(pika.ConnectionParameters('localhost'))
channel = connection.channel()
queues = sys.stdin.readlines()[1:-1]
for x in queues:
q = x.split()[0]
print 'Deleting %s...' %(q)
channel.queue_delete(queue=q)
connection.close()
Essentially, this is an iterative version of code of Shweta B. Patil.
a proper solution with streams and error handling is below:
const fs = require('fs')
const stream = require('stream')
app.get('/report/:chart_id/:user_id',(req, res) => {
const r = fs.createReadStream('path to file') // or any other way to get a readable stream
const ps = new stream.PassThrough() // <---- this makes a trick with stream error handling
stream.pipeline(
r,
ps, // <---- this makes a trick with stream error handling
(err) => {
if (err) {
console.log(err) // No such file or any other kind of error
return res.sendStatus(400);
}
})
ps.pipe(res) // <---- this makes a trick with stream error handling
})
with Node older then 10 you will need to use pump instead of pipeline.
You should link the progress bar to the task at hand (so that it measures the progress :D). For example, if you are FTPing a file, you can tell ftplib to grab a certain size buffer, let's say 128K, and then you add to your progress bar whatever percentage of the filesize 128k represents. If you are using the CLI, and your progress meter is 20 characters long, you would add one character when 1/20th of the file had transferred.
If the keystore is for tomcat then, after creating the keystore with the above answers, you must add a final step to create the "tomcat" alias for the key:
keytool -changealias -alias "1" -destalias "tomcat" -keystore keystore-file.jks
You can check the result with:
keytool -list -keystore keystore-file.jks -v

If you're using an emulator you can see the sharedPrefs.xml
file on the terminal with this commands:
adb root
cat /data/data/<project name>/shared_prefs/<xml file>
after that you can use adb unroot
if you dont want to keep the virtual device rooted.
It sounds like the populate method is what your looking for. First make small change to your post schema:
var postSchema = new Schema({
name: String,
postedBy: {type: mongoose.Schema.Types.ObjectId, ref: 'User'},
dateCreated: Date,
comments: [{body:"string", by: mongoose.Schema.Types.ObjectId}],
});
Then make your model:
var Post = mongoose.model('Post', postSchema);
Then, when you make your query, you can populate references like this:
Post.findOne({_id: 123})
.populate('postedBy')
.exec(function(err, post) {
// do stuff with post
});
One solution is to style the left border like so:
li { display: inline; }
li + li {
border-left: 1px solid;
margin-left:.5em;
padding-left:.5em;
}
However, this may not give you desirable results if the entire lists wraps, like it does in your example. I.e. it would give something like:
foo | bar | baz
| bob | bill
| judy

I hope this helps someone who has encountered the same problem especially when switching for windows OS to linux(ubuntu).
if some directory/folder does not exist but somehow you navigated to that directory in that case you can see this Error,
for example:
so, Generally this Error will show when Directory doesn't exist.
to fix this, simply run "cd;" or you can move to any other directory which exists.
Here is how I think you write an XOR comparison in C++:
bool a = true; // Test by changing to true or false
bool b = false; // Test by changing to true or false
if (a == !b) // THIS IS YOUR XOR comparison
{
// do whatever
}
Proof
XOR TABLE

The proof is that an exhaustive study of inputs and outputs shows that in the two tables, for every input set the result is always the identical in the two tables.
Therefore, the original question being how to write:
return (A==5) ^^ (B==5)
The answer would be
return (A==5) == !(B==5);
Or if you like, write
return !(A==5) == (B==5);
As a string, no. As an integer, %d.
Unless you count:
static char* enumStrings[] = { /* filler 0's to get to the first value, */
"enum0", "enum1",
/* filler for hole in the middle: ,0 */
"enum2", "enum3", .... };
...
printf("The value is %s\n", enumStrings[thevalue]);
This won't work for something like an enum of bit masks. At that point, you need a hash table or some other more elaborate data structure.
You can use IN operator as below
select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)
In my humble experience with postgres 9.6, cascade delete doesn't work in practice for tables that grow above a trivial size.
Factory methods should be considered as an alternative to constructors - mostly when constructors aren't expressive enough, ie.
class Foo{
public Foo(bool withBar);
}
is not as expressive as:
class Foo{
public static Foo withBar();
public static Foo withoutBar();
}
Factory classes are useful when you need a complicated process for constructing the object, when the construction need a dependency that you do not want for the actual class, when you need to construct different objects etc.
I think what you are looking for is
.style1 {
background: url('http://localhost/msite/images/12.PNG');
background-repeat: no-repeat;
background-position: center;
-webkit-background-size: contain;
-moz-background-size: contain;
-o-background-size: contain;

}
Hack grep's color function, and count how many color tags it prints out:
echo -e "a\nb b b\nc\ndef\nb e brb\nr" \
| GREP_COLOR="033" grep --color=always b \
| perl -e 'undef $/; $_=<>; s/\n//g; s/\x1b\x5b\x30\x33\x33/\n/g; print $_' \
| wc -l
The $innerListItem.position().top
is actually relative to the .scrollTop()
of its first positioned ancestor. So the way to calculate the correct $parentDiv.scrollTop()
value is to begin by making sure that $parentDiv
is positioned. If it doesn't already have an explicit position
, use position: relative
. The elements $innerListItem
and all its ancestors up to $parentDiv
need to have no explicit position. Now you can scroll to the $innerListItem
with:
// Scroll to the top
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top);
// Scroll to the center
$parentDiv.scrollTop($parentDiv.scrollTop() + $innerListItem.position().top
- $parentDiv.height()/2 + $innerListItem.height()/2);
Try this, replacing .myClassName
with the actual name of the class (but keep the period at the beginning).
$('.myClassName').each(function() {
alert( this.id );
});
So if the class is "test", you'd do $('.test').each(func...
.
This is the specific form of .each()
that iterates over a jQuery object.
The form you were using iterates over any type of collection. So you were essentially iterating over an array of characters t,e,s,t
.
Using that form of $.each()
, you would need to do it like this:
$.each($('.myClassName'), function() {
alert( this.id );
});
...which will have the same result as the example above.
The most fundamental thing here probably is that you don't want to transmit static images but only changes to the images, which essentially is analogous to video stream.
My best guess is some very efficient (and heavily specialized and optimized) motion compensation algorithm, because most of the actual change in generic desktop usage is linear movement of elements (scrolling text, moving windows, etc. opposed to transformation of elements).
The DirectX 3D performance of 1 FPS seems to confirm my guess to some extent.
One way to get this error is trying to add a usercontrol to a form while the project is set to compile as x64. Visual Studio throws the unhelpful: "Failed to load toolbox item . It will be removed from the toolbox."
Workaround is to design with "Any CPU" and compile to x64 as necessary.
Try run following alter table:
ALTER TABLE public.users
ALTER COLUMN "password" TYPE varchar(300)
USING "password"::varchar;
The text uses combining characters, also known as combining marks. See section 2.11 of Combining Characters in the Unicode Standard (PDF).
In Unicode, character rendering does not use a simple character cell model where each glyph fits into a box with given height. Combining marks may be rendered above, below, or inside a base character
So you can easily construct a character sequence, consisting of a base character and “combining above” marks, of any length, to reach any desired visual height, assuming that the rendering software conforms to the Unicode rendering model. Such a sequence has no meaning of course, and even a monkey could produce it (e.g., given a keyboard with suitable driver).
And you can mix “combining above” and “combining below” marks.
The sample text in the question starts with:
H
ͭ

Not quite a solution to the question but I thought it was worth noting the the approach I use when I have a long-living branch:
At the same time I create the branch, I also create a tag with the same name but with an -init
suffix, for example feature-branch
and feature-branch-init
.
(It is kind of bizarre that this is such a hard question to answer!)
EventHandler handler = (s, e) => MessageBox.Show("Woho");
button.Click += handler;
button.Click -= handler;
You could also do something like this:
df = df[['x', 'y', 'a', 'b']]
You can get the list of columns with:
cols = list(df.columns.values)
The output will produce something like this:
['a', 'b', 'x', 'y']
...which is then easy to rearrange manually before dropping it into the first function
I only use MicrosoftAdvertising.Mobile and Microsoft.Advertising.Mobile.UI and I am served ads. The SDK should only add the DLLs not reference itself.
Note: You need to explicitly set width and height Make sure the phone dialer, and web browser capabilities are enabled
Followup note: Make sure that after you've removed the SDK DLL, that the xmlns references are not still pointing to it. The best route to take here is
Here is the xmlns reference:
xmlns:AdNamepace="clr-namespace:Microsoft.Advertising.Mobile.UI;assembly=Microsoft.Advertising.Mobile.UI"
Then the ad itself:
<AdNamespace:AdControl x:Name="myAd" Height="80" Width="480" AdUnitId="yourAdUnitIdHere" ApplicationId="yourIdHere"/>
The collect
and collect!
methods are aliases to map

, so they can be used interchangeably. Here is an easy way to confirm that:
Array.instance_method(:map) == Array.instance_method(:collect)

}
}
array_example = {"God":"Jesus","Holy":"Spirit"};
fill(array_example);

echo "<a href=\"$entry\">$entry</a> | <a href=\"?delete=$entry\">Delete</a><br>";
}
}
closedir($handle);

This is It
You can easily access it in ConfigureServices, just persist it to a property during Startup method which is called first and gets it passed in, then you can access the property from ConfigureServices.
public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
...your code here...
CurrentEnvironment = env;
}
private IHostingEnvironment CurrentEnvironment{ get; set; }
public void ConfigureServices(IServiceCollection services)
{
string envName = CurrentEnvironment.EnvironmentName;
... your code here...
}
As a shorthand you can run:
docker tag d58 myname/server:latest
Where d58
represents the first 3 characters of the IMAGE ID,in this case, that's all you need.
Finally, you can remove the old image as follows:
docker rmi server
For v4 this is a known issue that won't be addressed in 4.0 but there is a workaround. Check https://github.com/select2/select2/issues/2830
In Eclipse, make sure you add your source folder in the project properties -> java build path -> source. Otherwise, the main() function may not be included in your project.
Yeah a CSS primer will not hurt here so you can do two things: 1 - within the tags of your html you can open a style tag like this:
<style type="text/css">
body {
margin: 0px;
}
/*
* this is the same as writing
* body { margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px;}
* I'm adding px here for clarity sake but the unit is not really needed if you have 0
* look into em, pt and % for other unit types
* the rules are always clockwise: top, right, bottom, left
*/
</style>
2- the above though will only work on the page you have this code embeded, so if if you wanted to reuse this in 10 files, then you will have to copy it over on all 10 files, and if you wanted to make a change let's say have a margin of 5px instead, you would have to open all those files and make the edit. That's why using an external style sheet is a golden rule in front end coding. So save the body declaration in a separate file named style.css for example and from your add this to your html instead:
<link rel="stylesheet" type="text/css" href="style.css"/>
Now you can put this in the of all pages that will benefit from these styles and whenever needed to change them you will only need to do so in one place. Hope it helps. Cheers

Despite its very explicit and forceful description, RETURN did not work for me inside a stored procedure (to skip further execution). I had to modify the condition logic. Happens on both SQL 2008, 2008 R2:
create proc dbo.prSess_Ins
(
@sSessID varchar( 32 )
, @idSess int out
)
as
begin
set nocount on
select @id= idSess
from tbSess
where sSessID = @sSessID
if @idSess > 0 return -- exit sproc here
begin tran
insert tbSess ( sSessID ) values ( @sSessID )
select @idSess= scope_identity( )
commit
end
had to be changed into:
if @idSess is null
begin
begin tran
insert tbSess ( sSessID ) values ( @sSessID )
select @idSess= scope_identity( )
commit
end
Discovered as a result of finding duplicated rows. Debugging PRINTs confirmed that @idSess had value greater than zero in the IF check - RETURN did not break execution!

Might give strange behavior if both listMerchants and listStatus are both null.

This should also work on Linux and Mac too.
String is immutable.
Why? Check here.
StringBuffer is not. It is thread safe.

I had to add !important
to get it to work. I also made my own class button-primary-override

On *nix, you can use comm. The answer to the question is:
comm -1 -2 file1.sorted file2.sorted
# where file1 and file2 are sorted and piped into *.sorted
Here's the full usage of comm
:
comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2.
Also note that it is important to sort the files before using comm, as mentioned in the man pages.

You don't use the :
syntax - pull
always modifies the currently checked-out branch. Thus:
git pull origin my_remote_branch
while you have my_local_branch
checked out will do what you want.
Since you already have the tracking branch set, you don't even need to specify - you could just do...
git pull
while you have my_local_branch
checked out, and it will update from the tracked branch.
if you just want to stopping insecure warning like:

do:
requests.METHOD("https://www.google.com", verify=False)
verify=False
is the key, followings are not good at it:
requests.packages.urllib3.disable_warnings()
or
urllib3.disable_warnings()
but, you HAVE TO know, that might cause potential security risks.
For me, the problem was twofold: First, the version of IIS I was dealing with didn't know about the .woff2
MIME type, only about .woff
. I fixed that using IIS Manager at the server level, not at the web app level, so the setting wouldn't get overridden with each new app deployment. (Under IIS Manager, I went to MIME types, and added the missing .woff2
, then updated .woff
.)
Second, and more importantly, I was bundling bootstrap.css
along with some other files as "~/bundles/css/site"
. Meanwhile, my font files were in "~/fonts"
. bootstrap.css
looks for the glyphicon fonts in "../fonts"
, which translated to "~/bundles/fonts"
-- wrong path.
In other words, my bundle path was one directory too deep. I renamed it to "~/bundles/siteCss"
, and updated all the references to it that I found in my project. Now bootstrap looked in "~/fonts"
for the glyphicon files, which worked. Problem solved.
Before I fixed the second problem above, none of the glyphicon
font files were loading. The symptom was that all instances of glyphicon
glyphs in the project just showed an empty box. However, this symptom only occurred in the deployed versions of the web app, not on my dev machine. I'm still not sure why that was the case.
Based on a feature mentioned in this answer to another question I have found a very generally applicable solution for placing labels on a bar chart.
Other solutions unfortunately do not work in many cases, because the spacing between label and bar is either given in absolute units of the bars or is scaled by the height of the bar. The former only works for a narrow range of values and the latter gives inconsistent spacing within one plot. Neither works well with logarithmic axes.
The solution I propose works independent of scale (i.e. for small and large numbers) and even correctly places labels for negative values and with logarithmic scales because it uses the visual unit points
for offsets.
I have added a negative number to showcase the correct placement of labels in such a case.
The value of the height of each bar is used as a label for it. Other labels can easily be used with Simon's for rect, label in zip(rects, labels)
snippet.

This produces the following output:

From http://php.net/manual/en/function.serialize.php :
Generates a storable representation of a value. This is useful for storing or passing PHP values around without losing their type and structure.
Essentially, it takes a php array or object and converts it to a string (which you can then transmit or store as you see fit).
Unserialize is used to convert the string back to an object.
You won't get real HTML rendering to <canvas>
per se currently, because canvas context does not have functions to render HTML elements.
There are some emulations:
html2canvas project http://html2canvas.hertzen.com/index.html (basically a HTML renderer attempt built on Javascript + canvas)
HTML to SVG to <canvas>
might be possible depending on your use case:
https://github.com/miohtama/Krusovice/blob/master/src/tools/html2svg2canvas.js
Also if you are using Firefox you can hack some extended permissions and then render a DOM window to <canvas>
You can use the SpeechSynthesisUtterance
with a function like say:
function say(m) {
var msg = new SpeechSynthesisUtterance();
var voices = window.speechSynthesis.getVoices();
msg.voice = voices[10];
msg.voiceURI = "native";
msg.volume = 1;
msg.rate = 1;
msg.pitch = 0.8;
msg.text = m;
msg.lang = 'en-US';
speechSynthesis.speak(msg);
}
Then you only need to call say(msg)
when using it.
Update: Look at Google's Developer Blog that is about Voice Driven Web Apps Introduction to the Web Speech API.
With current TypeScript Version 1.8.9 I use typed Enums:
export enum Option {
OPTION1 = <any>'this is option 1',
OPTION2 = <any>'this is option 2'
}
with results in this Javascript object:
Option = {
"OPTION1": "this is option 1",
"OPTION2": "this is option 2",
"this is option 1": "OPTION1",
"this is option 2": "OPTION2"
}
so I have to query through keys and values and only return values:
let optionNames: Array<any> = [];
for (let enumValue in Option) {
let optionNameLength = optionNames.length;
if (optionNameLength === 0) {
this.optionNames.push([enumValue, Option[enumValue]]);
} else {
if (this.optionNames[optionNameLength - 1][1] !== enumValue) {
this.optionNames.push([enumValue, Option[enumValue]]);
}
}
}
And I receive the option keys in an Array:
optionNames = [ "OPTION1", "OPTION2" ];
This has been more than adequately answered, but you may find this useful: The Function Pointer Tutorials. It is a truly comprehensive treatment of the subject in five chapters!

firstly u have to import numpy library (refer code for making a numpy array)
shape
only gives the output only if the variable is attribute of numpy library .in other words it must be a np.array or any other data structure of numpy.
Eg.
`>>> import numpy
>>> a=numpy.array([[1,1],[1,1]])
>>> a.shape

As described in the Apple Worldwide Developer Relations Intermediate Certificate Expiration:
The previous Apple Worldwide Developer Relations Certification Intermediate Certificate expired on February 14, 2016 and the renewed certificate must now be used when signing Apple Wallet Passes, push packages for Safari Push Notifications, Safari Extensions, and submissions to the App Store, Mac App Store, and App Store for Apple TV.
All developers should download and install the renewed certificate on their development systems and servers. All apps will remain available on the App Store for iOS, Mac, and Apple TV.
The new valid certificate will look like the following:
It will display (this certificate is valid) with a green mark.
So, go to your Key Chain Access. Just delete the old certificate and replace it with the new one (renewed certificate) as Apple described in the document. Mainly the problem is only with the Apple push notification service and extensions as described in the Apple document.
You can also check the listing of certificates in https://www.apple.com/certificateauthority/
Certificate Revocation List:
Now this updated certificate will expire on 2023-02-08.
If you could not see the old certificate then go to the System Keychains and from edit menu and select the option Show Expired Certificates.
Now you can see the following certificate that you have to delete:
Here's how I solved this issue:
Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse("vnd.youtube://" + video_id));
startActivity(intent);
Now that I've done some more research, it looks like I only needed 'vnd.youtube:VIDEO_ID' instead of two slashes after the colon (':' vs. '://'):
http://it-ride.blogspot.com/2010/04/android-youtube-intent.html
I tried most of the suggestions here and they didn't really work very well with all of the supposed "direct" methods raising exceptions. I would assume that, with my method, if the YouTube app is NOT installed, the OS has a default fallback position of something other than crashing the app. The app is theoretically only going on devices with the YouTube app on them anyway, so this should be a non-issue.
LocalDate.of( 1985 , 1 , 1 )
…or…
LocalDate.of( 1985 , Month.JANUARY , 1 )
The java.util.Date
, java.util.Calendar
, and java.text.SimpleDateFormat
classes were rushed too quickly when Java first launched and evolved. The classes were not well designed or implemented. Improvements were attempted, thus the deprecations you’ve found. Unfortunately the attempts at improvement largely failed. You should avoid these classes altogether. They are supplanted in Java 8 by new classes.
A java.util.Date has both a date and a time portion. You ignored the time portion in your code. So the Date class will take the beginning of the day as defined by your JVM’s default time zone and apply that time to the Date object. So the results of your code will vary depending on which machine it runs or which time zone is set. Probably not what you want.
If you want just the date, without the time portion, such as for a birth date, you may not want to use a Date
object. You may want to store just a string of the date, in ISO 8601 format of YYYY-MM-DD
. Or use a LocalDate
object from Joda-Time (see below).
First thing to learn in Java: Avoid the notoriously troublesome java.util.Date & java.util.Calendar classes bundled with Java.
As correctly noted in the answer by user3277382, use either Joda-Time or the new java.time.* package in Java 8.
DateTimeZone timeZoneNorway = DateTimeZone.forID( "Europe/Oslo" );
DateTime birthDateTime_InNorway = new DateTime( 1985, 1, 1, 3, 2, 1, timeZoneNorway );
DateTimeZone timeZoneNewYork = DateTimeZone.forID( "America/New_York" );
DateTime birthDateTime_InNewYork = birthDateTime_InNorway.toDateTime( timeZoneNewYork );
DateTime birthDateTime_UtcGmt = birthDateTime_InNorway.toDateTime( DateTimeZone.UTC );
LocalDate birthDate = new LocalDate( 1985, 1, 1 );
Dump to console…
System.out.println( "birthDateTime_InNorway: " + birthDateTime_InNorway );
System.out.println( "birthDateTime_InNewYork: " + birthDateTime_InNewYork );
System.out.println( "birthDateTime_UtcGmt: " + birthDateTime_UtcGmt );
System.out.println( "birthDate: " + birthDate );
When run…
birthDateTime_InNorway: 1985-01-01T03:02:01.000+01:00
birthDateTime_InNewYork: 1984-12-31T21:02:01.000-05:00
birthDateTime_UtcGmt: 1985-01-01T02:02:01.000Z
birthDate: 1985-01-01
In this case the code for java.time is nearly identical to that of Joda-Time.
We get a time zone (ZoneId
), and construct a date-time object assigned to that time zone (ZonedDateTime
). Then using the Immutable Objects pattern, we create new date-times based on the old object’s same instant (count of nanoseconds since epoch) but assigned other time zone. Lastly we get a LocalDate
which has no time-of-day nor time zone though notice the time zone applies when determining that date (a new day dawns earlier in Oslo than in New York for example).
ZoneId zoneId_Norway = ZoneId.of( "Europe/Oslo" );
ZonedDateTime zdt_Norway = ZonedDateTime.of( 1985 , 1 , 1 , 3 , 2 , 1 , 0 , zoneId_Norway );
ZoneId zoneId_NewYork = ZonedId.of( "America/New_York" );
ZonedDateTime zdt_NewYork = zdt_Norway.withZoneSameInstant( zoneId_NewYork );
ZonedDateTime zdt_Utc = zdt_Norway.withZoneSameInstant( ZoneOffset.UTC ); // Or, next line is similar.
Instant instant = zdt_Norway.toInstant(); // Instant is always in UTC.
LocalDate localDate_Norway = zdt_Norway.toLocalDate();
The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date
, Calendar
, & SimpleDateFormat
.
The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.
To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.
You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.*
classes.
Where to obtain the java.time classes?
The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval
, YearWeek
, YearQuarter
, and more.
A bit late for an answer but just updated fiddle with some best practice
var myApp = angular.module('myApp',[]);
myApp.factory('UserService', function() {
var userService = {};
userService.name = "HI Atul";
userService.ChangeName = function (value) {
userService.name = value;
};
return userService;
});
function MyCtrl($scope, UserService) {
$scope.name = UserService.name;
$scope.updatedname="";
$scope.changeName=function(data){
$scope.updateServiceName(data);
}
$scope.updateServiceName = function(name){
UserService.ChangeName(name);
$scope.name = UserService.name;
}
}
To show both:
<div style="height:250px; width:550px; overflow-x:scroll ; overflow-y: scroll; padding-bottom:10px;"> </div>
Hide X Axis:
<div style="height:250px; width:550px; overflow-x:hidden; overflow-y: scroll; padding-bottom:10px;"> </div>
Hide Y Axis:
<div style="height:250px; width:550px; overflow-x:scroll ; overflow-y: hidden; padding-bottom:10px;"> </div>
'.'.join()
or ".".join()
.. So any string instance has the method join()
Well, if it is useful, I have had several problems with cmake, including this one. They all disappeared when I fix the global variable (in my case the MinGW Codeblocks) PATH in the system. When the codeblocks install is not in default, and for some unknow reason, this global variable does not point to the right place. Check if the path of Codeblocks or MinGW are correct:
Right click on "My Computer"> Properties> Advanced Properties or Advanced> Environment Variables> to Change the PATH variable
It worked for me;)

Javascript can not directly set session values. For setting session values from javascript I do ajax call as follows.
At ASPx file or html,
<script type="text/javascript">
$(function(){
//Getting values from session and saving in javascript variable.
// But this will be executed only at document.ready.
var firstName = '<%= Session["FirstName"] ?? "" %>';
var lastName = '<%= Session["LastName"] ?? "" %>';
$("#FirstName").val(firstName);
$("#LastName").val(lastName);
$('Button').click(function(){
//Posting values to save in session
$.post(document.URL+'?mode=ajax',
{'FirstName':$("#FirstName").val(),
'LastName':$("#LastName").val()
} );
});
});
At Server side,
protected void Page_Load(object sender, EventArgs e)
{
if(Request.QueryString["mode"] != null && Request.QueryString["mode"] == "ajax")
{
//Saving the variables in session. Variables are posted by ajax.
Session["FirstName"] = Request.Form["FirstName"] ?? "";
Session["LastName"] = Request.Form["LastName"] ?? "";
}
}
For getting session values, as said by Shekhar and Rajeev
var firstName = '<%= Session["FirstName"] ?? "" %>';
Hope this helps.
Just FYI, the below command worked in seaborn 0.8.1 so I guess the initial answer is still valid.
sns_plot = sns.pairplot(data, hue='species', size=3)
sns_plot.savefig("output.png")
Just use .empty()
:
// snip...
}).done(function (data) {
// Clear drop down list
$(dropdown).empty(); // <<<<<< No more issue here
// Fill drop down list with new data
$(data).each(function () {
// snip...
There's also a more concise way to build up the options:
// snip...
$(data).each(function () {
$("<option />", {
val: this.value,
text: this.text
}).appendTo(dropdown);
});
It is used in transaction management to ensure that any errors result in the transaction being rolled back.
I added a ticket to add an option of some sort here:
https://github.com/pydata/pandas/issues/1450
In the meantime, result.fillna('')
should do what you want
EDIT: in the development version (to be 0.8.0 final) if you specify an empty list of na_values
, empty strings will stay empty strings in the result
This solution requires the Apache Commons IO library to be added to the build path. It works by reading the entire file and writing each line back but only if the search term is not contained.
public static void removeLineFromFile(File targetFile, String searchTerm)
throws IOException
{
StringBuffer fileContents = new StringBuffer(
FileUtils.readFileToString(targetFile));
String[] fileContentLines = fileContents.toString().split(
System.lineSeparator());
emptyFile(targetFile);
fileContents = new StringBuffer();
for (int fileContentLinesIndex = 0; fileContentLinesIndex < fileContentLines.length; fileContentLinesIndex++)
{
if (fileContentLines[fileContentLinesIndex].contains(searchTerm))
{
continue;
}
fileContents.append(fileContentLines[fileContentLinesIndex] + System.lineSeparator());
}
FileUtils.writeStringToFile(targetFile, fileContents.toString().trim());
}
private static void emptyFile(File targetFile) throws FileNotFoundException,
IOException
{
RandomAccessFile randomAccessFile = new RandomAccessFile(targetFile, "rw");
randomAccessFile.setLength(0);
randomAccessFile.close();
}
You can do this by using JQuery.
For example ,
<a href="your URL" id="navigate"> click here </a>
Your JQuery
will be,
$(document).ready(function(){
$('a').on('mousedown', stopNavigate);
$('a').on('mouseleave', function () {
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
});
});
function stopNavigate(){
$(window).off('beforeunload');
}
And to get the Leave message alert will be,
$(window).on('beforeunload', function(){
return 'Are you sure you want to leave?';
});
$(window).on('unload', function(){
logout();
});
This solution works in all browsers and I have tested it.
Also check this answer from here: Cannot manually edit applicationhost.config
The answer is simple, if not that obvious: win2008 is 64bit, notepad++ is 32bit. When you navigate to Windows\System32\inetsrv\config using explorer you are using a 64bit program to find the file. When you open the file using using notepad++ you are trying to open it using a 32bit program. The confusion occurs because, rather than telling you that this is what you are doing, windows allows you to open the file but when you save it the file's path is transparently mapped to Windows\SysWOW64\inetsrv\Config.
So in practice what happens is you open applicationhost.config using notepad++, make a change, save the file; but rather than overwriting the original you are saving a 32bit copy of it in Windows\SysWOW64\inetsrv\Config, therefore you are not making changes to the version that is actually used by IIS. If you navigate to the Windows\SysWOW64\inetsrv\Config you will find the file you just saved.
How to get around this? Simple - use a 64bit text editor, such as the normal notepad that ships with windows.
I couldn't find an answer that would solve this:
[{name:"Vehicle.Make", value: "Honda"}, {name:"Vehicle.VIN", value: "123"}]
This calls for this object:
{Vehicle: {Make: "Honda", "VIN": "123"}}
So I had to write a serializer of my own that would solve this:
function(formArray){
var obj = {};
$.each(formArray, function(i, pair){
var cObj = obj, pObj, cpName;
$.each(pair.name.split("."), function(i, pName){
pObj = cObj;
cpName = pName;
cObj = cObj[pName] ? cObj[pName] : (cObj[pName] = {});
});
pObj[cpName] = pair.value;
});
return obj;
}
Maybe it will help somebody.
One more example for lists:
// constructs the elements in place.
emplace_back("element");
// creates a new object and then copies (or moves) that object.
push_back(ExplicitDataType{"element"});
Thanks for the research FIRESTICK is a solution for non Android based but there's another one Im using if you guys want to try it let me know...
LG, VIZIO, SAMSUNG and PANASONIC TVs are not android based, and you cannot run APKs off of them... You should just buy a fire stick and call it a day. The only TVs that are android-based, and you can install APKs are: SONY, PHILIPS and SHARP, PHILCO and TOSHIBA.

Path Variables dialog has nothing to do with the environment variables.
Environment variables can be specified in your OS or customized in the Run configuration:
If only the columns are required then DataTable.Clone()
can be used. With Clone
function only the schema will be copied. But DataTable.Copy()
copies both the structure and data
E.g.
DataTable dt = new DataTable();
dt.Columns.Add("Column Name");
dt.Rows.Add("Column Data");
DataTable dt1 = dt.Clone();
DataTable dt2 = dt.Copy();
dt1
will have only the one column but dt2
will have one column with one row.
In case anyone is still looking for this functionality: I made an Android library that has this ability and much more, called ExpandableFab (https://github.com/nambicompany/expandable-fab).
The Material Design spec refers to this functionality as 'Speed Dial' and ExpandableFab implements it along with many additional features.
Nearly everything is customizable (colors, text, size, placement, margins, animations and more) and optional (don't need an Overlay, or FabOptions, or Labels, or icons, etc). Every property can be accessed or set through XML layouts or programmatically - whatever you prefer.
Written 100% in Kotlin but comes with full JavaDoc and KDoc (published API is well documented). Also comes with an example app so you can see different use cases with 0 coding.

I think this should be java.net.SocketException as its definition is stated for a TCP error.
/**
* Thrown to indicate that there is an error in the underlying

Python 2 will automatically set the type based on the size of the value. A guide of max values can be found below.
The Max value of the default Int in Python 2 is 65535, anything above that will be a long
For example:
>> print type(65535)
<type 'int'>
>>> print type(65536*65536)
<type 'long'>
In Python 3 the long datatype has been removed and all integer values are handled by the Int class. The default size of Int will depend on your CPU architecture.
For example:
The min/max values of each type can be found below:
If the size of your Int exceeds the limits mentioned above, python will automatically change it's type and allocate more memory to handle this increase in min/max values. Where in Python 2, it would convert into 'long', it now just converts into the next size of Int.
Example: If you are using a 32 bit operating system, your max value of an Int will be 2147483647 by default. If a value of 2147483648 or more is assigned, the type will be changed to Int64.
There are different ways to check the size of the int and it's memory allocation.
Note: In Python 3, using the built-in type() method will always return <class 'int'>
no matter what size Int you are using.
All you have to do is:
You will be able to see historical attributions (using git blame
) and full history of changes (using git log
) for both files.
Suppose you want to create a copy of file foo
called bar
. In that case the workflow you'd use would look like this:
git mv foo bar
git commit
SAVED=`git rev-parse HEAD`
git reset --hard HEAD^
git mv foo copy
git commit
git merge $SAVED # This will generate conflicts
git commit -a # Trivially resolved like this
git mv copy foo
git commit
After you execute the above commands, you end up with a revision history that looks like this:
( revision history ) ( files )
ORIG_HEAD foo
/ \ / \
SAVED ALTERNATE bar copy
\ / \ /
MERGED bar,copy
| |
RESTORED bar,foo
When you ask Git about the history of foo
, it will:
copy
between MERGED and RESTORED,copy
came from the ALTERNATE parent of MERGED, andfoo
between ORIG_HEAD and ALTERNATE.From there it will dig into the history of foo
.
When you ask Git about the history of bar
, it will:
bar
came from the SAVED parent of MERGED, and foo
between ORIG_HEAD and SAVED.From there it will dig into the history of foo
.
It's that simple. :)
You just need to force Git into a merge situation where you can accept two traceable copies of the file(s), and we do this with a parallel move of the original (which we soon revert).
Another thing that can cause this error is creating a model with the centering/scaling standardize function from the arm package -- m <- standardize(lm(y ~ x, data = train))
If you then try predict(m)
, you get the same error as in this question.
The -9
is the signal_number, and specifies that the kill message sent should be of the KILL (non-catchable, non-ignorable) type.
kill -9 pid
Which is same as below.
kill -SIGKILL pid
Without specifying a signal_number the default is -15, which is TERM (software termination signal). Typing kill <pid>
is the same as kill -15 <pid>
.
In a few words: The constructor is called first, then any @FXML
annotated fields are populated, then initialize()
is called.
This means the constructor does not have access to @FXML
fields referring to components defined in the .fxml file, while initialize()
does have access to them.
Quoting from the Introduction to FXML:
[...] the controller can define an initialize() method, which will be called once on an implementing controller when the contents of its associated document have been completely loaded [...] This allows the implementing class to perform any necessary post-processing on the content.
Short answer: Don't do it.
Longer answer: Use WCF. It's here to replace Asmx.
see this answer for example, or the first comment on this one.
John Saunders: ASMX is a legacy technology, and should not be used for new development. WCF or ASP.NET Web API should be used for all new development of web service clients and servers. One hint: Microsoft has retired the ASMX Forum on MSDN.
As for comment ... well, if you have to, you have to. I'll leave you in the competent hands of the other answers then. (Even though it's funny it has issues, and if it does, why are you doing it in VS2013 to begin with ?)
Assuming that you know the table name, and want the names of the data columns you can use the listed code will do it in a simple and elegant way to my taste:
import sqlite3
def get_col_names():
#this works beautifully given that you know the table name
conn = sqlite3.connect("t.db")
c = conn.cursor()
c.execute("select * from tablename")
return [member[0] for member in c.description]
Use git reflog
to find the hashes of previously checked out commits.
A shortcut command to get to your last checked out branch (not sure if this work correctly with detached HEAD and intermediate commits though) is git checkout -
