UPDATE: 9/24/16 Angular 2.0 Stable
This question gets a lot of traffic still, so, I wanted to update it. With the insanity of changes from Alpha, Beta, and 7 RC candidates, I stopped updating my SO answers until they went stable.
This is the perfect case for using Subjects and ReplaySubjects
I personally prefer to use ReplaySubject(1)
as it allows the last stored value to be passed when new subscribers attach even when late:
let project = new ReplaySubject(1);
//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result));
http.get('path/to/whatever/projects/1234').subscribe(result => {
//push onto subject
project.next(result));
//add delayed subscription AFTER loaded
setTimeout(()=> project.subscribe(result => console.log('Delayed Stream:', result)), 3000);
});
//Output
//Subscription Streaming: 1234
//*After load and delay*
//Delayed Stream: 1234
So even if I attach late or need to load later I can always get the latest call and not worry about missing the callback.
This also lets you use the same stream to push down onto:
project.next(5678);
//output
//Subscription Streaming: 5678
But what if you are 100% sure, that you only need to do the call once? Leaving open subjects and observables isn't good but there's always that "What If?"
That's where AsyncSubject comes in.
let project = new AsyncSubject();
//subscribe
project.subscribe(result => console.log('Subscription Streaming:', result),
err => console.log(err),
() => console.log('Completed'));
http.get('path/to/whatever/projects/1234').subscribe(result => {
//push onto subject and complete
project.next(result));
project.complete();
//add a subscription even though completed
setTimeout(() => project.subscribe(project => console.log('Delayed Sub:', project)), 2000);
});
//Output
//Subscription Streaming: 1234
//Completed
//*After delay and completed*
//Delayed Sub: 1234
Awesome! Even though we closed the subject it still replied with the last thing it loaded.
Another thing is how we subscribed to that http call and handled the response. Map is great to process the response.
public call = http.get(whatever).map(res => res.json())
But what if we needed to nest those calls? Yes you could use subjects with a special function:
getThing() {
resultSubject = new ReplaySubject(1);
http.get('path').subscribe(result1 => {
http.get('other/path/' + result1).get.subscribe(response2 => {
http.get('another/' + response2).subscribe(res3 => resultSubject.next(res3))
})
})
return resultSubject;
}
var myThing = getThing();
But that's a lot and means you need a function to do it. Enter FlatMap:
var myThing = http.get('path').flatMap(result1 =>
http.get('other/' + result1).flatMap(response2 =>
http.get('another/' + response2)));
Sweet, the var
is an observable that gets the data from the final http call.
OK thats great but I want an angular2 service!
I got you:
import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { ReplaySubject } from 'rxjs';
@Injectable()
export class ProjectService {
public activeProject:ReplaySubject<any> = new ReplaySubject(1);
constructor(private http: Http) {}
//load the project
public load(projectId) {
console.log('Loading Project:' + projectId, Date.now());
this.http.get('/projects/' + projectId).subscribe(res => this.activeProject.next(res));
return this.activeProject;
}
}
//component
@Component({
selector: 'nav',
template: `<div>{{project?.name}}<a (click)="load('1234')">Load 1234</a></div>`
})
export class navComponent implements OnInit {
public project:any;
constructor(private projectService:ProjectService) {}
ngOnInit() {
this.projectService.activeProject.subscribe(active => this.project = active);
}
public load(projectId:string) {
this.projectService.load(projectId);
}
}
I'm a big fan of observers and observables so I hope this update helps!
Original Answer
I think this is a use case of using a Observable Subject or in Angular2
the EventEmitter
.
In your service you create a EventEmitter
that allows you to push values onto it. In Alpha 45 you have to convert it with toRx()
, but I know they were working to get rid of that, so in Alpha 46 you may be able to simply return the EvenEmitter
.
class EventService {
_emitter: EventEmitter = new EventEmitter();
rxEmitter: any;
constructor() {
this.rxEmitter = this._emitter.toRx();
}
doSomething(data){
this.rxEmitter.next(data);
}
}
This way has the single EventEmitter
that your different service functions can now push onto.
If you wanted to return an observable directly from a call you could do something like this:
myHttpCall(path) {
return Observable.create(observer => {
http.get(path).map(res => res.json()).subscribe((result) => {
//do something with result.
var newResultArray = mySpecialArrayFunction(result);
observer.next(newResultArray);
//call complete if you want to close this stream (like a promise)
observer.complete();
});
});
}
That would allow you do this in the component:
peopleService.myHttpCall('path').subscribe(people => this.people = people);
And mess with the results from the call in your service.
I like creating the EventEmitter
stream on its own in case I need to get access to it from other components, but I could see both ways working...
Here's a plunker that shows a basic service with an event emitter: Plunkr

Give BinaryTree<T, Comparator>::Node
a subtreeHeight
data member, initialized to 0 in its constructor, and update automatically every time with:
template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::Node::setLeft (std::shared_ptr<Node>& node) {
const std::size_t formerLeftSubtreeSize = left ? left->subtreeSize : 0;
left = node;
if (node) {
node->parent = this->shared_from_this();
subtreeSize++;
node->depthFromRoot = depthFromRoot + 1;
const std::size_t h = node->subtreeHeight;
if (right)
subtreeHeight = std::max (right->subtreeHeight, h) + 1;
else
subtreeHeight = h + 1;
}
else {
subtreeSize -= formerLeftSubtreeSize;
subtreeHeight = right ? right->subtreeHeight + 1 : 0;
}
}
template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::Node::setRight (std::shared_ptr<Node>& node) {
const std::size_t formerRightSubtreeSize = right ? right->subtreeSize : 0;
right = node;
if (node) {
node->parent = this->shared_from_this();
subtreeSize++;
node->depthFromRoot = depthFromRoot + 1;
const std::size_t h = node->subtreeHeight;
if (left)
subtreeHeight = std::max (left->subtreeHeight, h) + 1;
else
subtreeHeight = h + 1;
}
else {
subtreeSize -= formerRightSubtreeSize;
subtreeHeight = left ? left->subtreeHeight + 1 : 0;
}
}
Note that data members subtreeSize
and depthFromRoot
are also updated.
These functions are called when inserting a node (all tested), e.g.
template <typename T, typename Comparator>
inline std::shared_ptr<typename BinaryTree<T, Comparator>::Node>
BinaryTree<T, Comparator>::Node::insert (BinaryTree& tree, const T& t, std::shared_ptr<Node>& node) {
if (!node) {
std::shared_ptr<Node> newNode = std::make_shared<Node>(tree, t);
node = newNode;
return newNode;
}
if (getComparator()(t, node->value)) {
std::shared_ptr<Node> newLeft = insert(tree, t, node->left);
node->setLeft(newLeft);
}
else {
std::shared_ptr<Node> newRight = insert(tree, t, node->right);
node->setRight(newRight);
}
return node;
}
If removing a node, use a different version of removeLeft
and removeRight
by replacing subtreeSize++;
with subtreeSize--;
. Algorithms for rotateLeft
and rotateRight
can be adapted without much problem either. The following was tested and passed:
template <typename T, typename Comparator>
void BinaryTree<T, Comparator>::rotateLeft (std::shared_ptr<Node>& node) { // The root of the rotation is 'node', and its right child is the pivot of the rotation. The pivot will rotate counter-clockwise and become the new parent of 'node'.
std::shared_ptr<Node> pivot = node->right;
pivot->subtreeSize = node->subtreeSize;
pivot->depthFromRoot--;
node->subtreeSize--; // Since 'pivot' will no longer be in the subtree rooted at 'node'.
const std::size_t a = pivot->left ? pivot->left->subtreeHeight + 1 : 0; // Need to establish node->heightOfSubtree before pivot->heightOfSubtree is established, since pivot->heightOfSubtree depends on it.
node->subtreeHeight = node->left ? std::max(a, node->left->subtreeHeight + 1) : std::max<std::size_t>(a,1);
if (pivot->right) {
node->subtreeSize -= pivot->right->subtreeSize; // The subtree rooted at 'node' loses the subtree rooted at pivot->right.
pivot->subtreeHeight = std::max (pivot->right->subtreeHeight, node->subtreeHeight) + 1;
}
else
pivot->subtreeHeight = node->subtreeHeight + 1;
node->depthFromRoot++;
decreaseDepthFromRoot(pivot->right); // Recursive call for the entire subtree rooted at pivot->right.
increaseDepthFromRoot(node->left); // Recursive call for the entire subtree rooted at node->left.
pivot->parent = node->parent;
if (pivot->parent) { // pivot's new parent will be its former grandparent, which is not nullptr, so the grandparent must be updated with a new left or right child (depending on whether 'node' was its left or right child).
if (pivot->parent->left == node)
pivot->parent->left = pivot;
else
pivot->parent->right = pivot;
}
node->setRightSimple(pivot->left); // Since pivot->left->value is less than pivot->value but greater than node->value. We use the NoSizeAdjustment version because the 'subtreeSize' values of 'node' and 'pivot' are correct already.
pivot->setLeftSimple(node);
if (node == root) {
root = pivot;
root->parent = nullptr;
}
}
where
inline void decreaseDepthFromRoot (std::shared_ptr<Node>& node) {adjustDepthFromRoot(node, -1);}
inline void increaseDepthFromRoot (std::shared_ptr<Node>& node) {adjustDepthFromRoot(node, 1);}
template <typename T, typename Comparator>
inline void BinaryTree<T, Comparator>::adjustDepthFromRoot (std::shared_ptr<Node>& node, int adjustment) {
if (!node)
return;
node->depthFromRoot += adjustment;
adjustDepthFromRoot (node->left, adjustment);
adjustDepthFromRoot (node->right, adjustment);
}

Function is a set of logic that can be used to manipulate data.
While, Method is function that is used to manipulate the data of the object where it belongs. So technically, if you have a function that is not completely related to your class but was declared in the class, its not a method; It's called a bad design.
a='foo'
b='baaz'
a.__add__(b)
out: 'foobaaz'
The minimum configuration to properly run sqlplus
from the shell is to set ORACLE_HOME
and LD_LIBRARY_PATH
. For ease of use, you might want to set the PATH
accordingly too.
Assuming you have unzipped the required archives in /opt/oracle/instantclient_11_1
:
$ export ORACLE_HOME=/opt/oracle/instantclient_11_1
$ export LD_LIBRARY_PATH="$ORACLE_HOME"
$ export PATH="$ORACLE_HOME:$PATH"
$ sqlplus

...
With AngularJS 1.4 and up, two services can handle the process of url-encoding data for POST requests, eliminating the need to manipulate the data with transformRequest
or using external dependencies like jQuery:
$httpParamSerializerJQLike
- a serializer inspired by jQuery's .param()
(recommended)
$httpParamSerializer
- a serializer used by Angular itself for GET requests
Example usage
$http({
url: 'some/api/endpoint',
method: 'POST',
data: $httpParamSerializerJQLike($scope.appForm.data), // Make sure to inject the service you choose to the controller
headers: {
'Content-Type': 'application/x-www-form-urlencoded' // Note the appropriate header
}
}).then(function(response) { /* do something here */ });
$httpParamSerializerJQLike
and $httpParamSerializer
differentIn general, it seems $httpParamSerializer
uses less "traditional" url-encoding format than $httpParamSerializerJQLike
when it comes to complex data structures.
For example (ignoring percent encoding of brackets):
• Encoding an array
{sites:['google', 'Facebook']} // Object with array property
sites[]=google&sites[]=facebook // Result with $httpParamSerializerJQLike
sites=google&sites=facebook // Result with $httpParamSerializer
• Encoding an object
{address: {city: 'LA', country: 'USA'}} // Object with object property
address[city]=LA&address[country]=USA // Result with $httpParamSerializerJQLike
address={"city": "LA", country: "USA"} // Result with $httpParamSerializer
Don't write if
statements without a corresponding else
. Once you add the else
to your fragment you'll see that your true

are in fact the last expressions of the function.

If your intent is to copy the found files into /home/shantanu/tosend
, you have the order of the arguments to cp
reversed:
find /home/shantanu/processed/ -name '*2011*.xml' -exec cp "{}" /home/shantanu/tosend \;
Please, note: the find
command use {}
as placeholder for matched file.
Use "spacer" divs to surround the div you want to center. Works best with a fluid design. Be sure to give the spacers height, or else they will not work.
<style>

#content{width=80%;}
div.spacer{width=10%; height=10px;}
</style>
<div class="row">
<div class="spacer"></div>
<div id="content">...</div>

Your question as I understand it is divided in two parts, part one being you need a better understanding of the Naive Bayes classifier & part two being the confusion surrounding Training set.
In general all of Machine Learning Algorithms need to be trained for supervised learning tasks like classification, prediction etc. or for unsupervised learning tasks like clustering.
During the training step, the algorithms are taught with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like Neural Networks, SVM, Bayesian etc. are based upon.
So in a general Machine Learning project basically you have to divide your input set to a Development Set (Training Set + Dev-Test Set) & a Test Set (or Evaluation set). Remember your basic objective would be that your system learns and classifies new inputs which they have never seen before in either Dev set or test set.
The test set typically has the same format as the training set. However, it is very important that the test set be distinct from the training corpus: if we simply reused the training set as the test set, then a model that simply memorized its input, without learning how to generalize to new examples, would receive misleadingly high scores.
In general, for an example, 70% of our data can be used as training set cases. Also remember to partition the original set into the training and test sets randomly.
Now I come to your other question about Naive Bayes.
To demonstrate the concept of Naïve Bayes Classification, consider the example given below:
As indicated, the objects can be classified as either GREEN
or RED
. Our task is to classify new cases as they arrive, i.e., decide to which class label they belong, based on the currently existing objects.
Since there are twice as many GREEN
objects as RED
, it is reasonable to believe that a new case (which hasn't been observed yet) is twice as likely to have membership GREEN
rather than RED
. In the Bayesian analysis, this belief is known as the prior probability. Prior probabilities are based on previous experience, in this case the percentage of GREEN
and RED
objects, and often used to predict outcomes before they actually happen.
Thus, we can write:
Prior Probability of GREEN
: number of GREEN objects / total number of objects
Prior Probability of RED
: number of RED objects / total number of objects
Since there is a total of 60
objects, 40
of which are GREEN
and 20 RED
, our prior probabilities for class membership are:
Prior Probability for GREEN
: 40 / 60
Prior Probability for RED
: 20 / 60
Having formulated our prior probability, we are now ready to classify a new object (WHITE
circle in the diagram below). Since the objects are well clustered, it is reasonable to assume that the more GREEN
(or RED
) objects in the vicinity of X, the more likely that the new cases belong to that particular color. To measure this likelihood, we draw a circle around X which encompasses a number (to be chosen a priori) of points irrespective of their class labels. Then we calculate the number of points in the circle belonging to each class label. From this we calculate the likelihood:
From the illustration above, it is clear that Likelihood of X
given GREEN
is smaller than Likelihood of X
given RED
, since the circle encompasses 1
GREEN
object and 3
RED
ones. Thus:
Although the prior probabilities indicate that X
may belong to GREEN
(given that there are twice as many GREEN
compared to RED
) the likelihood indicates otherwise; that the class membership of X
is RED
(given that there are more RED
objects in the vicinity of X
than GREEN
). In the Bayesian analysis, the final classification is produced by combining both sources of information, i.e., the prior and the likelihood, to form a posterior probability using the so-called Bayes' rule (named after Rev. Thomas Bayes 1702-1761).
Finally, we classify X as RED
since its class membership achieves the largest posterior probability.
This VBA code will refresh all pivot tables/charts in the workbook.
Sub RefreshAllPivotTables()
Dim PT As PivotTable
Dim WS As Worksheet
For Each WS In ThisWorkbook.Worksheets
For Each PT In WS.PivotTables

Another non-programatic option is:
This will refresh the pivot table each time the workbook is opened.
This works on IE7+, is standards compliant, and allows differing heights.

The above answer only deal with DOM parser (that normally reads the entire file in memory and parse it, what for a big file is a problem), you could use a SAX parser that uses less memory and is faster (anyway that depends on your code).
SAX parser callback some functions when it find a start of element, end of element, attribute, text between elements, etc, so it can parse the document and at the same time you get what you need.
Some example code:

You are looking for --build-arg

I had this edge case, where I checked out a previous version of the code in which my file directory structure was different:
git checkout 1.87.1

... other warnings ...
Note: checking out '1.87.1'.
You are in 'detached HEAD' state. You can look around, make experimental
changes and commit them, and you can discard any commits you make in this
state without impacting any branches by performing another checkout.
If you want to create a new branch to retain commits you create, you may
do so (now or later) by using -b with the checkout command again.
Example:
git checkout -b <new-branch-name>
HEAD is now at 50a7153d7... Merge branch 'hotfix/1.87.1'
In a case like this you may need to use --force (when you know that going back to the original branch and discarding changes is a safe thing to do).

Put the following in your .cs file:
using System.Linq;
You will then be able to use the following extension method from System.Linq.Enumerable:
public static TSource[] ToArray<TSource>(this System.Collections.Generic.IEnumerable<TSource> source)
I.e.
IEnumerable<object> query = ...;
object[] bob = query.ToArray();
This actually makes sense, in some way, considering how (relative) paths are treated usually:
string GetFullPath(string path)
{
string baseDir = @"C:\Users\Foo.Bar";
return Path.Combine(baseDir, path);
}
// Get full path for RELATIVE file path
GetFullPath("file.txt"); // = C:\Users\Foo.Bar\file.txt
// Get full path for ROOTED file path
GetFullPath(@"C:\Temp\file.txt"); // = C:\Temp\file.txt
The real question is: Why are paths, which start with "\"
, considered "rooted"? This was new to me too, but it works that way on Windows:
new FileInfo("\windows"); // FullName = C:\Windows, Exists = True
new FileInfo("windows"); // FullName = C:\Users\Foo.Bar\Windows, Exists = False
As defined in the MySQL Glossary:
In MySQL, physically, a schema is synonymous with a database. You can substitute the keyword
SCHEMA
instead ofDATABASE
in MySQL SQL syntax, for example usingCREATE SCHEMA
instead ofCREATE DATABASE
.Some other database products draw a distinction. For example, in the Oracle Database product, a schema represents only a part of a database: the tables and other objects owned by a single user.
The problem is in the import
line. You are importing a module, not a class. Assuming your file is named other_file.py
(unlike java, again, there is no such rule as "one class, one file"):
from other_file import findTheRange
if your file is named findTheRange too, following java's convenions, then you should write
from findTheRange import findTheRange
you can also import it just like you did with random
:
import findTheRange
operator = findTheRange.findTheRange()
Some other comments:
a) @Daniel Roseman is right. You do not need classes here at all. Python encourages procedural programming (when it fits, of course)
b) You can build the list directly:
randomList = [random.randint(0, 100) for i in range(5)]
c) You can call methods in the same way you do in java:
largestInList = operator.findLargest(randomList)
smallestInList = operator.findSmallest(randomList)
d) You can use built in function, and the huge python library:
largestInList = max(randomList)
smallestInList = min(randomList)
e) If you still want to use a class, and you don't need self
, you can use @staticmethod
:
class findTheRange():
@staticmethod
def findLargest(_list):
#stuff...
I modified my activate script to source the file .virtualenvrc
, if it exists in the current directory, and to save/restore PYTHONPATH
on activate/deactivate.
You can find the patched activate
script here.. It's a drop-in replacement for the activate script created by virtualenv 1.11.6.
Then I added something like this to my .virtualenvrc
:
export PYTHONPATH="${PYTHONPATH:+$PYTHONPATH:}/some/library/path"
The fact that a class implements Comparable
means that you can take two objects from that class and compare them. Some classes, like certain collections (sort function in a collection) that keep objects in order rely on them being comparable (in order to sort you need to know which object is the "biggest" and so forth).

I have been working on a solution to finding the parent object of the current object for my own pet project. Adding a reference to the parent object within the current object creates a cyclic relationship between the two objects.
Consider -
var obj = {
innerObj: {},
setParent: function(){
this.innerObj.parent = this;
}
};
obj.setParent();
The variable obj will now look like this -
obj.innerObj.parent.innerObj.parent.innerObj...
This is not good. The only solution that I have found so far is to create a function which iterates over all the properties of the outermost Object until a match is found for the current Object and then that Object is returned.
Example -
var obj = {
innerObj: {
innerInnerObj: {}
}
};
var o = obj.innerObj.innerInnerObj,
found = false;
var getParent = function (currObj, parObj) {
for(var x in parObj){
if(parObj.hasOwnProperty(x)){
if(parObj[x] === currObj){
found = parObj;
}else if(typeof parObj[x] === 'object'){
getParent(currObj, parObj[x]);
}
}
}
return found;
};
var res = getParent(o, obj); // res = obj.innerObj
Of course, without knowing or having a reference to the outermost object, there is no way to do this. This is not a practical nor is it an efficient solution. I am going to continue to work on this and hopefully find a good answer for this problem.

I like Roy Osherove's naming strategy. It's the following:
[UnitOfWork_StateUnderTest_ExpectedBehavior]
It has every information needed on the method name and in a structured manner.
The unit of work can be as small as a single method, a class, or as large as multiple classes. It should represent all the things that are to be tested in this test case and are under control.
For assemblies, I use the typical .Tests
ending, which I think is quite widespread and the same for classes (ending with Tests
):
[NameOfTheClassUnderTestTests]
Previously, I used Fixture as suffix instead of Tests, but I think the latter is more common, then I changed the naming strategy.

You could use an extension method for fun. Typically I don't recommend attaching extension methods to such a general purpose class like string, but like I said this is fun. I borrowed @Luke's answer since there is no point in re-inventing the wheel.
[Test]
public void Should_remove_first_occurrance_of_string() {
var source = "ProjectName\\Iteration\\Release1\\Iteration1";
Assert.That(
source.RemoveFirst("\\Iteration"),
Is.EqualTo("ProjectName\\Release1\\Iteration1"));
}
public static class StringExtensions {
public static string RemoveFirst(this string source, string remove) {
int index = source.IndexOf(remove);
return (index < 0)
? source
: source.Remove(index, remove.Length);
}
}
If you use Kotlin, you can do the following:
1. On first, you should be create Interface
and implemented him in your Fragment
interface RefreshData {
fun refresh()
}
class YourFragment : Fragment(), RefreshData {
...
override fun refresh() {
//do what you want
}
}
2. Next step is add OnPageChangeListener
to your ViewPager
viewPager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {
override fun onPageScrollStateChanged(state: Int) { }
override fun onPageSelected(position: Int) {
viewPagerAdapter.notifyDataSetChanged()
viewPager.currentItem = position
}
override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) { }
})
3. override getItemPosition
in your Adapter
override fun getItemPosition(obj: Any): Int {
if (obj is RefreshData) {
obj.refresh()
}
return super.getItemPosition(obj)
}
first, last = some_list[0], some_list[-1]
Wrap the text in a span
or similar and use the following CSS:
.your-div {
position: relative;
}
.your-div span {
position: absolute;
bottom: 0;
right: 0;
}
First, you should download the suitable version for your system from here: https://pecl.php.net/package/mcrypt/1.0.3/windows
Then, you should copy php_mcrypt.dll
to ../xampp/php/ext/
and enable the extension by adding extension=mcrypt
to your xampp/php/php.ini
file.
There is a new one: http://hayatbiralem.com/blog/2015/05/15/responsive-bootstrap-tabs/
And also Codepen sample available here: http://codepen.io/hayatbiralem/pen/KpzjOL
No needs plugin. It uses just a little css and jquery.
Here's a sample tabs markup:
<ul class="nav nav-tabs nav-tabs-responsive">
<li class="active">
<a href="#tab1" data-toggle="tab">
<span class="text">Tab 1</span>
</a>
</li>
<li class="next">
<a href="#tab2" data-toggle="tab">
<span class="text">Tab 2</span>
</a>
</li>
<li>
<a href="#tab3" data-toggle="tab">
<span class="text">Tab 3</span>
</a>
</li>
...
</ul>
.. and jQuery codes are also here:
(function($) {
'use strict';
$(document).on('show.bs.tab', '.nav-tabs-responsive [data-toggle="tab"]', function(e) {
var $target = $(e.target);
var $tabs = $target.closest('.nav-tabs-responsive');
var $current = $target.closest('li');
var $parent = $current.closest('li.dropdown');
$current = $parent.length > 0 ? $parent : $current;
var $next = $current.next();
var $prev = $current.prev();
var updateDropdownMenu = function($el, position){
$el
.find('.dropdown-menu')
.removeClass('pull-xs-left pull-xs-center pull-xs-right')
.addClass( 'pull-xs-' + position );
};
$tabs.find('>li').removeClass('next prev');
$prev.addClass('prev');
$next.addClass('next');
updateDropdownMenu( $prev, 'left' );
updateDropdownMenu( $current, 'center' );
updateDropdownMenu( $next, 'right' );
});
})(jQuery);
Thanks, Varun Rathore
. It works perfectly!
For those who want graceful collapse from 4 items per row to 2 items per row depending on the screen width:
<ul class="list-group row">
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_1</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_2</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_3</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_4</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_5</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_6</li>
<li class="list-group-item col-xs-6 col-sm-4 col-md-3">Cell_7</li>
</ul>
Sharing what has worked for me in both Ubuntu and Windows. This is for python3. To do for python2, replace "3" with "2":

source /tmp/VIRTUAL/bin/activate
which python3
To install any package: pip install package
To get out of the virtual environment: deactivate

func renderImage(size: CGSize) -> UIImage {
return UIGraphicsImageRenderer(size: size).image { rendererContext in
// flip y axis
rendererContext.cgContext.translateBy(x: 0, y: size.height)
rendererContext.cgContext.scaleBy(x: 1, y: -1)
// draw image rotated/offsetted
rendererContext.cgContext.saveGState()
rendererContext.cgContext.translateBy(x: translate.x, y: translate.y)
rendererContext.cgContext.rotate(by: rotateRadians)
rendererContext.cgContext.draw(cgImage, in: drawRect)
rendererContext.cgContext.restoreGState()
}
}
From what I know, the correct syntax is:
function ChangeBackgroungImageOfTab(tabName, imagePrefix)
{
document.getElementById(tabName).style.backgroundImage = "url('buttons/" + imagePrefix + ".png')";
}
So basically, getElementById(tabName).backgroundImage
and split the string like:
"cssInHere('and" + javascriptOutHere + "/cssAgain')";
It is worth mentioning that the command works similarly on Linux:
git clone path/to/source/folder path/to/destination/folder
You'll run into issues with this if the object has loop in its object graph, e.g something like:
var object = {
aProperty: {
aSetting1: 1
},
};
object.ref = object;
In that case you might want to keep references of objects you've already walked through & exclude them from the iteration.
Also you can run into an issue if the object graph is too deep like:
var object = {
a: { b: { c: { ... }} }
};
You'll get too many recursive calls error. Both can be avoided:
function iterate(obj) {
var walked = [];
var stack = [{obj: obj, stack: ''}];
while(stack.length > 0)
{
var item = stack.pop();
var obj = item.obj;
for (var property in obj) {
if (obj.hasOwnProperty(property)) {
if (typeof obj[property] == "object") {
var alreadyFound = false;
for(var i = 0; i < walked.length; i++)
{
if (walked[i] === obj[property])
{
alreadyFound = true;
break;
}
}
if (!alreadyFound)
{
walked.push(obj[property]);
stack.push({obj: obj[property], stack: item.stack + '.' + property});
}
}
else
{
console.log(item.stack + '.' + property + "=" + obj[property]);
}
}
}
}
}
iterate(object);
You don't need 2 style attributes - just use one:
<img src="http://img705.imageshack.us/img705/119/original120x75.png"
style="height:100px;width:100px;" alt="25"/>
Consider, however, using a CSS class instead:
CSS:
.100pxSquare
{
width: 100px;
height: 100px;
}
HTML:
<img src="http://img705.imageshack.us/img705/119/original120x75.png"
class="100pxSquare" alt="25"/>

Use a generator:
common = (x for x in list1 if x in list2)
The advantage here is that this will return in constant time (nearly instant) even when using huge lists or other huge iterables.
For example,
list1 = list(range(0,10000000))
list2=list(range(1000,20000000))
common = (x for x in list1 if x in list2)
All other answers here will take a very long time with these values for list1 and list2.
You can then iterate the answer with
for i in common: print(i)
Or convert it to a list with
list(i)
Time package in Golang has some methods that might be worth looking.
func (Time) Format
func (t Time) Format(layout string) string Format returns a textual representation of the time value formatted according to layout, which defines the format by showing how the reference time,
Mon Jan 2 15:04:05 -0700 MST 2006 would be displayed if it were the value; it serves as an example of the desired output. The same display rules will then be applied to the time value. Predefined layouts ANSIC, UnixDate, RFC3339 and others describe standard and convenient representations of the reference time. For more information about the formats and the definition of the reference time, see the documentation for ANSIC and the other constants defined by this package.
Source (http://golang.org/pkg/time/#Time.Format)
I also found an example of defining the layout (http://golang.org/src/pkg/time/example_test.go)
func ExampleTime_Format() {
// layout shows by example how the reference time should be represented.
const layout = "Jan 2, 2006 at 3:04pm (MST)"
t := time.Date(2009, time.November, 10, 15, 0, 0, 0, time.Local)
fmt.Println(t.Format(layout))
fmt.Println(t.UTC().Format(layout))
// Output:
// Nov 10, 2009 at 3:00pm (PST)
// Nov 10, 2009 at 11:00pm (UTC)

In your 'encrypt' method, you should either get rid of the try/catch and instead add a try/catch around where you call encrypt (inside 'actionPerformed') or return null inside the catch within encrypt (that's the second error.
No difference as such.
Convert.ToInt32()
calls int.Parse()
internally
Except for one thing Convert.ToInt32()
returns 0
when argument is null
Otherwise both work the same way
Within Excel you need to set a reference to the VB script run-time library.
The relevant file is usually located at \Windows\System32\scrrun.dll
Microsoft Scripting Runtime
'scrrun.dll
file will be displayed below the listboxThis can also be done directly in the code if access to the VBA object model has been enabled.
Access can be enabled by ticking the check-box Trust access to the VBA project object model
found at File > Options > Trust Center > Trust Center Settings > Macro Settings
To add a reference:
Sub Add_Reference()
Application.VBE.ActiveVBProject.References.AddFromFile "C:\Windows\System32\scrrun.dll"
'Add a reference
End Sub
To remove a reference:
Sub Remove_Reference()
Dim oReference As Object
Set oReference = Application.VBE.ActiveVBProject.References.Item("Scripting")
Application.VBE.ActiveVBProject.References.Remove oReference
'Remove a reference
End Sub
If after calling "csrutil disabled" still your command does not work, try with "sudo" in terminal, for example:
sudo mv geckodriver /usr/local/bin
And it should work.
If you haven't already committed your changes, just use git checkout
to move to the new branch and then commit them normally - changes to files are not tied to a particular branch until you commit them.
If you have already committed your changes:
git log
and remember the SHA of the commit you want to move.git cherry-pick SHA
substituting the SHA from above.git reset HEAD~1
to reset back before your wrong-branch commit.cherry-pick
takes a given commit and applies it to the currently checked-out head, thus allowing you to copy the commit over to a new branch.
Use the new clipboard API, via navigator.clipboard
. It can be used like this:
navigator.clipboard.readText()
.then(text => {
console.log('Pasted content: ', text);
})
.catch(err => {
console.error('Failed to read clipboard contents: ', err);
});
Or with async syntax:
const text = await navigator.clipboard.readText();
Keep in mind that this will prompt the user with a permission request dialog box, so no funny business possible.
The above code will not work if called from the console. It only works when you run the code in an active tab. To run the code from your console you can set a timeout and click in the website window quickly:
setTimeout(async () => {
const text = await navigator.clipboard.readText();
console.log(text);
}, 2000);
Read more on the API and usage in the Google developer docs.
I found it very useful to build also a json message with repeated code, like this:
@POST
@Consumes("application/json")
@Produces("application/json")
public Response authUser(JsonObject authData) {
String email = authData.getString("email");
String password = authData.getString("password");
JSONObject json = new JSONObject();
if (email.equalsIgnoreCase(user.getEmail()) && password.equalsIgnoreCase(user.getPassword())) {
json.put("status", "success");
json.put("code", Response.Status.OK.getStatusCode());
json.put("message", "User " + authData.getString("email") + " authenticated.");
return Response.ok(json.toString()).build();
} else {
json.put("status", "error");
json.put("code", Response.Status.NOT_FOUND.getStatusCode());
json.put("message", "User " + authData.getString("email") + " not found.");
return Response.status(Response.Status.NOT_FOUND).entity(json.toString()).build();
}
}
If you want to apply styles only to an element which is its parents' first child, is it better to use :first-child
pseudo-class
.social:first-child{
border-bottom: dotted 1px #6d6d6d;
padding-top: 0;
}
.social{
border: 0;
width: 330px;
height: 75px;
float: right;
text-align: left;
padding: 10px 0;
}
Then, the rule .social
has both common styles and the last element's styles.
And .social:first-child
overrides them with first element's styles.
You could also use :last-child
selector, but :first-child
is more supported by old browsers: see
https://developer.mozilla.org/en-US/docs/CSS/:first-child#Browser_compatibility and https://developer.mozilla.org/es/docs/CSS/:last-child#Browser_compatibility.
I had the same problem when I used code-first migrations to build my database for an MVC 5 application. I eventually found the seed method in my configuration.cs file to be causing the issue. My seed method was creating a table entry for the table containing the foreign key before creating the entry with the matching primary key.
If lakes
is your DataFrame
, you can do something like
area_dict = dict(zip(lakes.area, lakes.count))
Since most of the answers to this question are between 2009 and 2014 (except for a comment in 2018), there should be an update to this.
I found a solution to the wrap-text problem brought up by Spongman on Jun 11 '14 at 23:20. He has an example here: jsfiddle.net/vPpD4
If you add the following in the CSS under the div tag in the jsfiddle.net/vPpD4 example, you get the desired wrap-text effect that I think Spongman was asking about. I don't know how far back this is applicable, but this works in all of the current (as of Dec 2020/Jan 2021) browsers available for Windows computers. Note: I have not tested this on the Apple Safari browser. I have also not tested this on any mobile devices.
div img {
float: left;
}
.clearfix::after {
content: "";
clear: both;
display: table;
}
I also added a border around the image, just so that the reader will understand where the edge of the image is and why the text wraps as it does. The resulting example looks is here: http://jsfiddle.net/tqg7hLzk/
The post needs an update after the links
option is deprecated.
Basically, links
is no longer needed because its main purpose, making container reachable by another by adding environment variable, is included implicitly with network
. When containers are placed in the same network, they are reachable by each other using their container name and other alias as host.
For docker run
, --link
is also deprecated and should be replaced by a custom network.
docker network create mynet
docker run -d --net mynet --name container1 my_image
docker run -it --net mynet --name container1 another_image
depends_on
expresses start order (and implicitly image pulling order), which was a good side effect of links
.
The following works in MVC5:
document.getElementById('theID').value = 'new value';
No, this is not working. And it's not just for you, in case you spent the last hour trying to find an answer for having your embeded videos open in HD.
Question: Oh, but how do you know this is not working anymore and there is no other alternative to make embeded videos open in a different quality?
Answer: Just went to Google's official documentation regarding Youtube's player parameters and there is not a single parameter that allows you to change its quality.
Also, hd=1
doesn't work either. More info here.
Apparently Youtube analyses the width and height of the user's window (or iframe) and automatically sets the quality based on this.
UPDATE:
As of 10 of April of 2018 it still doesn't work (see my comment on the accepted answer for more details).
What I can see from comments is that it MAY work sometimes, but some others it doesn't. The accepted answer states that "it measures the network speed and the screen and player sizes". So, by that, we can understand that I CANNOT force HD as YouTube will still do whatever it wants in case of low network speed/screen resolution. From my perspective everyone saying it works just have false positives on their hands and on the occasion they tested it worked for some random reason not related to the vq
parameter. If it was a valid parameter, Google would document it somewhere, and vq
isn't documented anywhere.
Click "View Detail..." a window will open where you can expand the "Inner Exception" my guess is that when you try to delete the record there is a reference constraint violation. The inner exception will give you more information on that so you can modify your code to remove any references prior to deleting the record.
Encountered this in Ubuntu for Windows, try running first
sudo apt-get update

Python has a in-built string method that does the work: index().
string.index(value, start, end)
Where:
def character_index():
string = "Hello World! This is an example sentence with no meaning."
match = "i"
return string.index(match)
print(character_index())
> 15
Let's say you need all the indexes where the character match
is and not just the first one.
The pythonic way would be to use enumerate()
.
def character_indexes():
string = "Hello World! This is an example sentence with no meaning."
match = "i"
indexes_of_match = []
for index, character in enumerate(string):
if character == match:
indexes_of_match.append(index)
return indexes_of_match
print(character_indexes())
# [15, 18, 42, 53]
Or even better with a list comprehension:
def character_indexes_comprehension():
string = "Hello World! This is an example sentence with no meaning."
match = "i"
return [index for index, character in enumerate(string) if character == match]
print(character_indexes_comprehension())
# [15, 18, 42, 53]
spans default to inline style, which you can't specify the width of.
display: inline-block;
would be a good way, except IE doesn't support it
you can, however, hack a multiple browser solution
UPDATE yourtable

I had this error. Nothing worked for me until I opened the SQLServer log file in the "MSSQL10_50" Log folder. That clearly stated which file could not be overwritten. It turned out that the .mdf file was being written into the "MSSQL10" data folder. I made sure that folder had the same SQLServer user permissions as the "MSSQL10_50" equivalent folder. Then it all worked.
The issue here is that the error detail is logged but not reported, so check the logs.
VARCHAR(MAX)
is big enough to accommodate TEXT
field. TEXT
, NTEXT
and IMAGE
data types of SQL Server 2000 will be deprecated in future version of SQL Server, SQL Server 2005 provides backward compatibility to data types but it is recommended to use new data types which are VARCHAR(MAX)
, NVARCHAR(MAX)
and VARBINARY(MAX)
.
I find the simplest way to explain "effectively final" is to imagine adding the final
modifier to a variable declaration. If, with this change, the program continues to behave in the same way, both at compile time and at run time, then that variable is effectively final.
You can also do this as well (shorter cut) instead of having to do instance declaration. You do this in JSON instead.
class Book {
public BookId: number;
public Title: string;
public Author: string;
public Price: number;
public Description: string;
}
var bks: Book[] = [];
bks.push({BookId: 1, Title:"foo", Author:"foo", Price: 5, Description: "foo"}); //This is all done in JSON.
By default they are stored here:
%commonprogramfiles%/Microsoft Shared/web server extensions/12/Logs
Using %commonprogramfiles% make it works in non-english systems.
RABL is probably the nicest solution to this that I've seen if you're looking for a cleaner alternative to ERb syntax. json_builder and argonaut, which are other solutions, both seem somewhat outdated and won't work with Rails 3.1 without some patching.
RABL is available via a gem or check out the GitHub repository; good examples too
I got the same error when trying to deploy to a Artifactory repository, the following solved the issue for me:
Go to the repository setting in artifactory and enable the point "Force Maven Authentication" and the 401 "Unauthorized" error should be gone. (Of course you need to supply your credentials in the settings.xml file at best in plain text to prevent issues)
I guess by default, even through you supply the right credentials in the settings.xml file, they don't get used and you get the Unauthorized exception.
Just to add another solution to the list, what I've found is that Visual Studio (2012 in my case) occasionally locks files under different processes.
So, on a crash, devenv.exe might still be running and holding onto the file(s). Alternatively (as I just discovered), vstestrunner or vstestdiscovery might be holding onto the file as well.
Kill all those processes and it might fix up the issue.
Well, your code is not reproducible so we will never know for sure, but this is what help('break')
says:
break breaks out of a for, while or repeat loop; control is transferred to the first statement outside the inner-most loop.
So yes, break
only breaks the current loop. You can also see it in action with e.g.:
for (i in 1:10)
{
for (j in 1:10)
{
for (k in 1:10)
{
cat(i," ",j," ",k,"\n")
if (k ==5) break
}
}
}
var form = $('#job-request-form')[0];
var formData = new FormData(form);
event.preventDefault();
$.ajax({
url: "/send_resume/", // the endpoint
type: "POST", // http method
processData: false,
contentType: false,
data: formData,
It worked for me! just set processData and contentType False.

I have the same problem that my app worked in Vs2013 but getting the error after updating to Vs2015.
@pst gave a great answer, but I'd like to mention that in Ruby the ternary operator is written on one line to be syntactically correct, unlike Perl and C where we can write it on multiple lines:
(true) ? 1 : 0
Normally Ruby will raise an error if you attempt to split it across multiple lines, but you can use the \
line-continuation symbol at the end of a line and Ruby will be happy:
(true) \
? 1 \
: 0
This is a simple example, but it can be very useful when dealing with longer lines as it keeps the code nicely laid out.
It's also possible to use the ternary without the line-continuation characters by putting the operators last on the line, but I don't like or recommend it:
(true) ?
1 :
0
I think that leads to really hard to read code as the conditional test and/or results get longer.
I've read comments saying not to use the ternary operator because it's confusing, but that is a bad reason to not use something. By the same logic we shouldn't use regular expressions, range operators ('..
' and the seemingly unknown "flip-flop" variation). They're powerful when used correctly, so we should learn to use them correctly.
Why have you put brackets around
true
?
Consider the OP's example:
<% question = question.size > 20 ? question.question.slice(0, 20)+"..." : question.question %>
Wrapping the conditional test helps make it more readable because it visually separates the test:
<% question = (question.size > 20) ? question.question.slice(0, 20)+"..." : question.question %>
Of course, the whole example could be made a lot more readable by using some judicious additions of whitespace. This is untested but you'll get the idea:
<% question = (question.size > 20) ? question.question.slice(0, 20) + "..." \
: question.question
%>
Or, more written more idiomatically:
<% question = if (question.size > 20)
question.question.slice(0, 20) + "..."
else
question.question
end
%>
It'd be easy to argument that readability suffers badly from question.question
too.
Assuming this branch isn't an external or a symlink, removing the branch should be as simple as:
svn rm branches/< mybranch >
svn ci -m "message"
If you'd like to do this in the repository then update to remove it from your working copy you can do something like:
svn rm http://< myurl >/< myrepo >/branches/< mybranch >
Then run:
svn update
This is a slightly modified version that lets you specify the name of the attribute in the scope, just as you would do with ng-model, usage:
<myUpload key="file"></myUpload>
Directive:
.directive('myUpload', function() {
return {
link: function postLink(scope, element, attrs) {
element.find("input").bind("change", function(changeEvent) {
var reader = new FileReader();
reader.onload = function(loadEvent) {
scope.$apply(function() {
scope[attrs.key] = loadEvent.target.result;
});
}
if (typeof(changeEvent.target.files[0]) === 'object') {
reader.readAsDataURL(changeEvent.target.files[0]);
};
});
},
controller: 'FileUploadCtrl',
template:
'<span class="btn btn-success fileinput-button">' +
'<i class="glyphicon glyphicon-plus"></i>' +
'<span>Replace Image</span>' +
'<input type="file" accept="image/*" name="files[]" multiple="">' +
'</span>',
restrict: 'E'
};
});
SELECT * FROM TABLENAME ORDER BY random() LIMIT 5;
In python 3 this is easy
myVariable = 5
for v in locals():
if id(v) == id("myVariable"):
print(v, locals()[v])
this will print:
myVariable 5
If you want to check for a specific class then you can use
if([MyClass class] == [myClassObj class]) {
//your object is instance of MyClass
}
An easy Method, Full control over 'from type' and 'to type', and only need to remember this code for future castings
DateTime.ParseExact(InputDate, "dd/MM/yyyy", CultureInfo.InvariantCulture).ToString("yyyy/MM/dd"));
If you want to redirect the output to a log file to look for errors or something. You can do something like this.
sqlplus -s <<EOF>> LOG_FILE_NAME user/passwd@host/db
#Your SQL code
EOF
If you have to do this often and you would like this to be cleaner in code you might like to have an extension method for this.
This is really obvious code, but still I think it can be useful to grab and make you save time.
/// <summary>
/// Put a string between double quotes.
/// </summary>
/// <param name="value">Value to be put between double quotes ex: foo</param>
/// <returns>double quoted string ex: "foo"</returns>
public static string AddDoubleQuotes(this string value)
{
return "\"" + value + "\"";
}
Then you may call foo.AddDoubleQuotes() or "foo".AddDoubleQuotes(), on every string you like.
Hope this help.
I searched for this very question and when I saw the answers I ended up creating something different (because I favor less code over most other things most of the time) that should work in the vast majority of cases. Basically turn the array into a string with array elements separated by some delimiter character, and then wrap the search value in the delimiter character and pass through instr.
Function is_in_array(value As String, test_array) As Boolean
If Not (IsArray(test_array)) Then Exit Function
If InStr(1, "'" & Join(test_array, "'") & "'", "'" & value & "'") > 0 _
Then is_in_array = True
End Function
And you'd execute the function like this:
test = is_in_array(1, array(1, 2, 3))
I split var all over the places, the only questionable places for me are internal short types, e.g. I prefer int i = 3;
over var i = 3;
All of these answers are simple and good. However, I always like to add an interactive mode to these scripts so that I can find false positives.
if [[ -n $inInteractiveMode ]]
then
echo -e -n "$oldFileName => $newFileName\nDo you want to do this change? [Y/n]: "
read run[[ -z $run || "$run" == "y" || "$run" == "Y" ]] && mv "$oldFileName" "$newFileName"
fi
Or make interactive mode the default and add a force flag (-f | --force) for automated scripts or if you're feeling daring. And this doesn't slow you down too much: the default response is "yes, I do want to rename" so you can just hit the enter key at each prompt (because of the ``-z $run\
test.
More with where in (list_of_items)
:
$linkIds = $user->links()->pluck('id')->toArray();
$tags = Tag::query()
->join('link_tag', function (JoinClause $join) use ($linkIds) {
$joinClause = $join->on('tags.id', '=', 'link_tag.tag_id');
$joinClause->on('link_tag.link_id', 'in', $linkIds ?: [-1], 'and', true);
})
->groupBy('link_tag.tag_id')
->get();
return $tags;
Hope it helpful ;)
Using base graphics, the standard way to do this is to use axes=FALSE, then create your own axes using Axis (or axis). For example,
x <- 1:20
y <- runif(20)
plot(x, y, axes=FALSE, frame.plot=TRUE)
Axis(side=1, labels=FALSE)
Axis(side=2, labels=FALSE)
The lattice equivalent is
library(lattice)
xyplot(y ~ x, scales=list(alternating=0))
Warning: this way is not a safe way, but is very easy to use. Use it wisely.
Use the eval function.
print eval('2 + 4')
Output:
6
You can even use variables or regular python code.
a = 5
print eval('a + 4')
Output:
9
You also can get return values:
d = eval('4 + 5')
print d
Output:
9
Or call functions:
def add(a, b):
return a + b
def subtract(a, b):
return a - b
a = 20
b = 10
print eval('add(a, b)')
print eval('subtract(a, b)')
Output:
30
10
In case you want to write a parser, maybe instead you can built a python code generator if that is easier and use eval to run the code. With eval you can execute any Python evalution.
Why eval is unsafe?
Since you can put literally anything in the eval, e.g. if the input argument is:
os.system(‘rm -rf /’)
It will remove all files on your system (at least on Linux/Unix). So only use eval when you trust the input.
If your install isn't already damaged, you can drop unwanted PostgreSQL servers ("clusters") using pg_dropcluster
. Use that in preference to a full purge and reinstall if you just want to restart with a fresh PostgreSQL instance.
$ pg_lsclusters
Ver Cluster Port Status Owner Data directory Log file
11 main 5432 online postgres /var/lib/postgresql/11/main /var/log/postgresql/postgresql-11-main.log
$ sudo systemctl stop postgresql@11-main
$ sudo pg_dropcluster --stop 11 main
$ sudo pg_createcluster --start 11 main
If you really need to do a full purge and reinstall, first make sure PostgreSQL isn't running. ps -C postgres
should show no results.
Now run:
apt-get --purge remove postgresql\*
to remove everything PostgreSQL from your system. Just purging the postgres
package isn't enough since it's just an empty meta-package.
Once all PostgreSQL packages have been removed, run:
rm -r /etc/postgresql/
rm -r /etc/postgresql-common/
rm -r /var/lib/postgresql/
userdel -r postgres
groupdel postgres
You should now be able to:
apt-get install postgresql
or for a complete install:
apt-get install postgresql-8.4 postgresql-contrib-8.4 postgresql-doc-8.4
This would work:
declare @test varchar(100)
set @test = 'this is a test'
while charindex(' ',@test ) > 0
begin
set @test = replace(@test, ' ', ' ')
end
select @test
If you want to save your numpy array (e.g. your_array = np.array([[1,2],[3,4]])
) to one cell, you could convert it first with your_array.tolist()
.
Then save it the normal way to one cell, with delimiter=';'
and the cell in the csv-file will look like this [[1, 2], [2, 4]]
Then you could restore your array like this:
your_array = np.array(ast.literal_eval(cell_string))
As already mentioned this can't be done with floats, they can't inherit heights, they're unaware of their siblings so for example the side two floats don't know the height of the centre content, so they can't inherit from anything.
Usually inherited height has to come from either an element which has an explicit height or if height: 100%;
has been passed down through the display tree to it.. The only thing I'm aware of that passes on height which hasn't come from top of the "tree" is an absolutely positioned element - so you could for example absolutely position all the top right bottom left sides and corners (you know the height and width of the corners anyway) And as you seem to know the widths (of left/right borders) and heights of top/bottom) borders, and the widths of the top/bottom centers, are easy at 100% - the only thing that needs calculating is the height of the right/left sides if the content grows -
This you can do, even without using all four positioning co-ordinates which IE6 /7 doesn't support
I've put up an example based on what you gave, it does rely on a fixed width (your frame), but I think it could work with a flexible width too? the uses of this could be cool for those fancy image borders we can't get support for until multiple background images or image borders become fully available.. who knows, I was playing, so just sticking it out there!
proof of concept example is here
You should check out if there is no DBMS administration and development platform working on your database (like pgAdmin), as this is probably the most popular cause of this error. If there is - commit the changes done and the problem is gone.
You can use the option -C
(or --directory
if you prefer long options) to give the target directory of your choice in case you are using the Gnu version of tar
. The directory should exist:
mkdir foo
tar -xzf bar.tar.gz -C foo
If you are not using a tar
capable of extracting to a specific directory, you can simply cd
into your target directory prior to calling tar
; then you will have to give a complete path to your archive, of course. You can do this in a scoping subshell to avoid influencing the surrounding script:
mkdir foo
(cd foo; tar -xzf ../bar.tar.gz) # instead of ../ you can use an absolute path as well
Or, if neither an absolute path nor a relative path to the archive file is suitable, you also can use this to name the archive outside of the scoping subshell:
TARGET_PATH=a/very/complex/path/which/might/even/be/absolute
mkdir -p "$TARGET_PATH"
(cd "$TARGET_PATH"; tar -xzf -) < bar.tar.gz
I have same error. Problem was that branch was deleted, released. But in PhpStorm I still could see it in remote branches. I could checkout as local branch. And then doing git pull was giving this error.
So need to check if this brnach really exists remotely.
Or, using datetimepicker plugin.
Somehow, where you are using Sentry, you're not using its Facade, but the class itself. When you call a class through a Facade you're not really using statics, it's just looks like you are.
Do you have this:
use Cartalyst\Sentry\Sentry;
In your code?
Ok, but if this line is working for you:
$user = $this->sentry->register(array( 'username' => e($data['username']), 'email' => e($data['email']), 'password' => e($data['password']) ));
So you already have it instantiated and you can surely do:
$adminGroup = $this->sentry->findGroupById(5);
In regards to multiple arrays in an object. For instance, you want to record modules for different courses
var course = {
InfoTech:["Information Systems","Internet Programming","Software Eng"],
BusComm:["Commercial Law","Accounting","Financial Mng"],
Tourism:["Travel Destination","Travel Services","Customer Mng"]
};
console.log(course.Tourism[1]);
console.log(course.BusComm);
console.log(course.InfoTech);

// populates list with initial values
for (Integer i : Arrays.asList(0,1,2,3,4,5,6,7))
numbers.add(i);
printList(numbers); // 0,1,2,3,4,5,6,7
// replaces each element with twice its value

For the line
line.split()
What are you splitting on? Looks like a CSV, so try
line.split(',')
Example:
"one,two,three".split() # returns one element ["one,two,three"]
"one,two,three".split(',') # returns three elements ["one", "two", "three"]
As @TigerhawkT3 mentions, it would be better to use the CSV module. Incredibly quick and easy method available here.
Using the -u
command-line switch works, but it is a little bit clumsy. It would mean that the program would potentially behave incorrectly if the user invoked the script without the -u
option. I usually use a custom stdout
, like this:
class flushfile:
def __init__(self, f):
self.f = f
def write(self, x):
self.f.write(x)
self.f.flush()
import sys
sys.stdout = flushfile(sys.stdout)
... Now all your print
calls (which use sys.stdout
implicitly), will be automatically flush
ed.
I have found the only reliable, portable method to be
bytes(bytearray([n]))
Just bytes([n]) does not work in python 2. Taking the scenic route through bytearray seems like the only reasonable solution.
Have a look at the "Jetty" web server Jetty. Superb piece of Open Source software that would seem to meet all your requirments.
If you insist on rolling your own then have a look at the "httpMessage" class.
If you are looking to block the execution of code with call to sleep
, then no, there is no method for that in JavaScript
.
JavaScript
does have setTimeout
method. setTimeout
will let you defer execution of a function for x milliseconds.
setTimeout(myFunction, 3000);
// if you have defined a function named myFunction
// it will run after 3 seconds (3000 milliseconds)
Remember, this is completely different from how sleep
method, if it existed, would behave.
function test1()
{
// let's say JavaScript did have a sleep function..
// sleep for 3 seconds
sleep(3000);
alert('hi');
}
If you run the above function, you will have to wait for 3 seconds (sleep
method call is blocking) before you see the alert 'hi'. Unfortunately, there is no sleep
function like that in JavaScript
.
function test2()
{
// defer the execution of anonymous function for
// 3 seconds and go to next line of code.
setTimeout(function(){
alert('hello');
}, 3000);
alert('hi');
}
If you run test2, you will see 'hi' right away (setTimeout
is non blocking) and after 3 seconds you will see the alert 'hello'.
I tested the previous answers found here: Assuming that we want the other four sheets to remain, the previous answers here did not work, because the other four sheets were deleted. In case we want them to remain use xlwings:
import xlwings as xw
import pandas as pd
filename = "test.xlsx"
df = pd.DataFrame([
("a", 1, 8, 3),
("b", 1, 2, 5),
("c", 3, 4, 6),
], columns=['one', 'two', 'three', "four"])
app = xw.App(visible=False)
wb = xw.Book(filename)
ws = wb.sheets["Sheet5"]
ws.clear()
ws["A1"].options(pd.DataFrame, header=1, index=False, expand='table').value = df
# If formatting of column names and index is needed as xlsxwriter does it,
# the following lines will do it (if the dataframe is not multiindex).
ws["A1"].expand("right").api.Font.Bold = True
ws["A1"].expand("down").api.Font.Bold = True
ws["A1"].expand("right").api.Borders.Weight = 2
ws["A1"].expand("down").api.Borders.Weight = 2
wb.save(filename)
app.quit()
SOLUTION: to prevent this error(for AWS LAMBDA):
In order to exit of "Nodejs event Loop" you must end the connection, and then reconnect. Add the next code to invoke the callback:
connection.end( function(err) {
if (err) {console.log("Error ending the connection:",err);}
// reconnect in order to prevent the"Cannot enqueue Handshake after invoking quit"
connection = mysql.createConnection({
host : 'rds.host',
port : 3306,
user : 'user',
password : 'password',
database : 'target database'
});
callback(null, {
statusCode: 200,
body: response,
});
});
Just wanted to clarify this for myself, while using the new reflection API based on TypeInfo
- where BindingFlags
is not available reliably (depending on target framework).
In the 'new' reflection, to get the static properties for a type (not including base class(es)) you have to do something like:
IEnumerable<PropertyInfo> props =
type.GetTypeInfo().DeclaredProperties.Where(p =>
(p.GetMethod != null && p.GetMethod.IsStatic) ||
(p.SetMethod != null && p.SetMethod.IsStatic));
Caters for both read-only or write-only properties (despite write-only being a terrible idea).
The DeclaredProperties
member, too doesn't distinguish between properties with public/private accessors - so to filter around visibility, you then need to do it based on the accessor you need to use. E.g - assuming the above call has returned, you could do:
var publicStaticReadable = props.Where(p => p.GetMethod != null && p.GetMethod.IsPublic);
There are some shortcut methods available - but ultimately we're all going to be writing a lot more extension methods around the TypeInfo
query methods/properties in the future. Also, the new API forces us to think about exactly what we think of as a 'private' or 'public' property from now on - because we must filter ourselves based on individual accessors.
HTML
<div id="mydiv" data-myval="10"></div>
JavaScript:
Using DOM's getAttribute()
property
var brand = mydiv.getAttribute("data-myval")//returns "10"
mydiv.setAttribute("data-myval", "20") //changes "data-myval" to "20"
mydiv.removeAttribute("data-myval") //removes "data-myval" attribute entirely
Using JavaScript's dataset
property
var myval = mydiv.dataset.myval //returns "10"
mydiv.dataset.myval = '20' //changes "data-myval" to "20"
mydiv.dataset.myval = null //removes "data-myval" attribute
Open Your .edmx file in XML editor and then remove tag from Tag and also change store:Schema="dbo" to Schema="dbo" and rebuild the solution now error will resolve and you will be able to save the data.
If you want to cast it to specific type (e.g. within tests) you can use ReadAsAsync extension method:
object yourTypeInstance = await response.Content.ReadAsAsync(typeof(YourType));
or following for synchronous code:
object yourTypeInstance = response.Content.ReadAsAsync(typeof(YourType)).Result;
Update: there is also generic option of ReadAsAsync<> which returns specific type instance instead of object-declared one:
YourType yourTypeInstance = await response.Content.ReadAsAsync<YourType>();
I guess this is where you are pointing at ..
<div id="divActivites" name="divActivites" style="border:thin">
<textarea id="inActivities" name="inActivities" style="border:solid">
</textarea>
</div>
Well. it must be written as border-width:thin
Here you go with the link (click here) check out the different types of Border-styles
you can also set the border width by writing the width in terms of pixels.. (like border-width:1px), minimum width is 1px.
.on()
is the recommended way to do all your event binding as of jQuery 1.7. It rolls all the functionality of both .bind()
and .live()
into one function that alters behavior as you pass it different parameters.
As you have written your example, there is no difference between the two. Both bind a handler to the click
event of #whatever
. on()
offers additional flexibility in allowing you to delegate events fired by children of #whatever
to a single handler function, if you choose.
// Bind to all links inside #whatever, even new ones created later.
$('#whatever').on('click', 'a', function() { ... });
In addition to the differences mentioned in other answers, there also is a speed difference. d = {} is over twice as fast:
python -m timeit -s "d = {}" "for i in xrange(500000): d.clear()"
10 loops, best of 3: 127 msec per loop
python -m timeit -s "d = {}" "for i in xrange(500000): d = {}"
10 loops, best of 3: 53.6 msec per loop
Provided answers are good, but I think they can be improved by adding an "architectural" perspective.
Investigation
MVC's Controller.Json
function is doing the job, but it is very poor at providing a relevant error in this case. By using Newtonsoft.Json.JsonConvert.SerializeObject
, the error specifies exactly what is the property that is triggering the circular reference. This is particularly useful when serializing more complex object hierarchies.
Proper architecture
One should never try to serialize data models (e.g. EF models), as ORM's navigation properties is the road to perdition when it comes to serialization. Data flow should be the following:
Database -> data models -> service models -> JSON string
Service models can be obtained from data models using auto mappers (e.g. Automapper). While this does not guarantee lack of circular references, proper design should do it: service models should contain exactly what the service consumer requires (i.e. the properties).
In those rare cases, when the client requests a hierarchy involving the same object type on different levels, the service can create a linear structure with parent->child relationship (using just identifiers, not references).
Modern applications tend to avoid loading complex data structures at once and service models should be slim. E.g.:
Use Let's Encrypt via Greenlock.js
I noticed that none of these answers show that adding a Intermediate Root CA to the chain, here are some zero-config examples to play with to see that:
Snippet:
var options = {
// this is the private key only
key: fs.readFileSync(path.join('certs', 'my-server.key.pem'))
// this must be the fullchain (cert + intermediates)
, cert: fs.readFileSync(path.join('certs', 'my-server.crt.pem'))
// this stuff is generally only for peer certificates
//, ca: [ fs.readFileSync(path.join('certs', 'my-root-ca.crt.pem'))]
//, requestCert: false
};
var server = https.createServer(options);
var app = require('./my-express-or-connect-app').create(server);
server.on('request', app);
server.listen(443, function () {
console.log("Listening on " + server.address().address + ":" + server.address().port);
});
var insecureServer = http.createServer();
server.listen(80, function () {
console.log("Listening on " + server.address().address + ":" + server.address().port);
});
This is one of those things that's often easier if you don't try to do it directly through connect or express, but let the native https
module handle it and then use that to serve you connect / express app.
Also, if you use server.on('request', app)
instead of passing the app when creating the server, it gives you the opportunity to pass the server
instance to some initializer function that creates the connect / express app (if you want to do websockets over ssl on the same server, for example).
Very late to the party but I found an answer for MVC (5) I disabled the CheckBox and added a HiddenFor BEFORE the checkbox, so when it is posting if finds the Hidden field first and uses that value. This does work.
<div class="form-group">
@Html.LabelFor(model => model.Carrier.Exists, new { @class = "control-label col-md-2" })
<div class="col-md-10">
@Html.HiddenFor(model => model.Carrier.Exists)
@Html.CheckBoxFor(model => model.Carrier.Exists, new { @disabled = "disabled" })
@Html.ValidationMessageFor(model => model.Carrier.Exists)

Full Screen Custom Alert Dialog Class in Kotlin
Create XML file, same as you would an activity
Create AlertDialog custom class
class Your_Class(context:Context) : AlertDialog(context){
init {
requestWindowFeature(Window.FEATURE_NO_TITLE)
setCancelable(false)
}
override fun onCreate(savedInstanceState: Bundle?) {
super.onCreate(savedInstanceState)
setContentView(R.layout.your_Layout)
val window = this.window
window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT)
//continue custom code here
//call dismiss() to close
}
}
Call the dialog within the activity
val dialog = Your_Class(this)
//can set some dialog options here
dialog.show()
Note**: If you do not want your dialog to be full screen, delete the following lines
val window = this.window
window?.setLayout(WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT)
Then edit the layout_width & layout_height of your top layout within your XML file to be either wrap_content or a fixed DP value.
I generally do not recommend using fixed DP as you would likely want your app to be adaptable to multiple screen sizes, however if you keep your size values small enough you should be fine
When you call loadTeachers()
on DOMReady the context of this
will not be the #CourseSelect
element.
You can fix this by triggering a change()
event on the #CourseSelect
element on load of the DOM:
$("#CourseSelect").change(loadTeachers).change(); // or .trigger('change');
Alternatively can use $.proxy
to change the context the function runs under:
$("#CourseSelect").change(loadTeachers);
$.proxy(loadTeachers, $('#CourseSelect'))();
Or the vanilla JS equivalent of the above, bind()
:
$("#CourseSelect").change(loadTeachers);
loadTeachers.bind($('#CourseSelect'));
Like Maiasaura, I prefer ggplot2
. The transparent reference manual is one of the reasons.
However, this is one quick way to get it done.
require(ggplot2)
data(diamonds)
qplot(carat, price, data = diamonds, colour = color)
# example taken from Hadley's ggplot2 book
And cause someone famous said, plot related posts are not complete without the plot, here's the result:
Here's a couple of references: qplot.R example, note basically this uses the same diamond dataset I use, but crops the data before to get better performance.
http://ggplot2.org/book/ the manual: http://docs.ggplot2.org/current/
In kotlin there is no replaceAll, so I created this loop to replace repeated values ??in a string or any variable.
var someValue = "https://www.google.com.br/"
while (someValue.contains(".")) {
someValue = someValue.replace(".", "")
}
Log.d("newValue :", someValue)
// in that case the stitches have been removed
//https://wwwgooglecombr/
Server.MapPath specifies the relative or virtual path to map to a physical directory.

1 returns the current physical directory of the file (e.g. aspx) being executedServer.MapPath("..")
returns the parent directoryServer.MapPath("~")
returns the physical path to the root of the applicationServer.MapPath("/")
returns the physical path to the root of the domain name (is not necessarily the same as the root of the application)An example:
Let's say you pointed a web site application (http://www.example.com/
) to
C:\Inetpub\wwwroot
and installed your shop application (sub web as virtual directory in IIS, marked as application) in
D:\WebApps\shop
For example, if you call Server.MapPath()
in following request:
http://www.example.com/shop/products/GetProduct.aspx?id=2342
then:
Server.MapPath(".")
1 returns D:\WebApps\shop\products
Server.MapPath("..")
returns D:\WebApps\shop
Server.MapPath("~")
returns D:\WebApps\shop
Server.MapPath("/")
returns C:\Inetpub\wwwroot
Server.MapPath("/shop")
returns D:\WebApps\shop
If Path starts with either a forward slash (/
) or backward slash (\
), the MapPath()
returns a path as if Path was a full, virtual path.
If Path doesn't start with a slash, the MapPath()
returns a path relative to the directory of the request being processed.
Note: in C#, @
is the verbatim literal string operator meaning that the string should be used "as is" and not be processed for escape sequences.
Footnotes
Server.MapPath(null)
and Server.MapPath("")
will produce this effect too.just use this,
utf8_encode($string);
you've to replace your $arr
with $string
.
I think it will work...try this.
This is the normal behavior and the reason is that your sqlCommandHandlerService.persist
method needs a TX when being executed (because it is marked with @Transactional
annotation). But when it is called inside processNextRegistrationMessage
, because there is a TX available, the container doesn't create a new one and uses existing TX. So if any exception occurs in sqlCommandHandlerService.persist
method, it causes TX to be set to rollBackOnly
(even if you catch the exception in the caller and ignore it).
To overcome this you can use propagation levels for transactions. Have a look at this to find out which propagation best suits your requirements.
Well after a colleague came to me with a couple of questions about a similar situation, I feel this needs a bit of clarification.
Although propagations solve such issues, you should be VERY careful about using them and do not use them unless you ABSOLUTELY understand what they mean and how they work. You may end up persisting some data and rolling back some others where you don't expect them to work that way and things can go horribly wrong.
What also works and is even nicer for long, multiline texts, is putting your text indented on the next line, after a pipe or greater-than sign:
text: >
Op dit plein stond het hoofdkantoor van de NIROM: Nederlands Indische
Radio Omroep
A pipe preserves newlines, a gt-sign turns all the following lines into one long string.
Adding to the knowledge base. We had the same issue on Bamboo. The problem was resolved by using the Environmental Properties on Bamboo.
DISPLAY=":1"
Adding the value as system properties in the pom.xml, or the command line did not work.

Based on Piotr Migdals response I want to give an alternate solution enabling the possibility for a vector of strings:
myVectorOfStrings <- c("foo", "bar")
matchExpression <- paste(myVectorOfStrings, collapse = "|")
# [1] "foo|bar"
df %>% select(matches(matchExpression))
Making use of the regex OR
operator (|
)
ATTENTION: If you really have a plain vector of column names (and do not need the power of RegExpression), please see the comment below this answer (since it's the cleaner solution).
There are two basic ways:
url(../../images/image.png)
or
url(/Web/images/image.png)
I prefer the latter, as it's easier to work with and works from all locations in the site (so useful for inline image paths too).
Mind you, I wouldn't do so much deep nesting of folders. It seems unnecessary and makes life a bit difficult, as you've found.
I think you're looking for header(name,value) method. See WebResource.header(String, Object)
Note it returns a Builder though, so you need to save the output in your webResource var.
If after the installation curl-dev luarocks does not see the headers:
find /usr -name 'curl.h'
Example: /usr/include/x86_64-linux-gnu/curl/curl.h
luarocks install lua-cURL CURL_INCDIR=/usr/include/x86_64-linux-gnu/
Having accessor methods is preferred to accessing fields directly, because it controls how fields are accessed (may impose data checking etc) and fits with interfaces (interfaces can not requires fields to be present, only methods).
To get the value you would do this:
document.getElementById("genderf").value;
But to check, whether the radio button is checked or selected:
document.getElementById("genderf").checked;
If all you want to do is run your main class (without compiling the .java
files on which the main class doesn't depend), then you can do the following:
cd <root-package-directory>
javac <complete-path-to-main-class>
or
javac -cp <root-package-directory> <complete-path-to-main-class>
javac
would automatically resolve all the dependencies and compile all the dependencies as well.
When the lists aren't extremely long, this is the best way I know:
function getIndex(val) {
for (var i = 0; i < imageList.length; i++) {
if (imageList[i] === val) {
return i;
}
}
}
var imageList = [100, 200, 300, 400, 500];
var index = getIndex(200);
The model presents a placeholder to hold the information you want to display on the view. It could be a string, which is in your above example, or it could be an object containing bunch of properties.
Example 1
If you have...
return new ModelAndView("welcomePage","WelcomeMessage","Welcome!");
... then in your jsp, to display the message, you will do:-
Hello Stranger! ${WelcomeMessage} // displays Hello Stranger! Welcome!
Example 2
If you have...
MyBean bean = new MyBean();
bean.setName("Mike!");
bean.setMessage("Meow!");
return new ModelAndView("welcomePage","model",bean);
... then in your jsp, you can do:-
Hello ${model.name}! {model.message} // displays Hello Mike! Meow!
You can add
from functools import reduce
before you use the reduce.

In my case, we have time series from different devices but some devices could not send any value during some period. So we should create NA values for every device and time period and after that do fillna.
df = pd.DataFrame([["device1", 1, 'first val of device1'], ["device2", 2, 'first val of device2'], ["device3", 3, 'first val of device3']])
df.pivot(index=1, columns=0, values=2).fillna(method='ffill').unstack().reset_index(name='value')
Result:
0 1 value
0 device1 1 first val of device1
1 device1 2 first val of device1
2 device1 3 first val of device1
3 device2 1 None
4 device2 2 first val of device2
5 device2 3 first val of device2
6 device3 1 None
7 device3 2 None
8 device3 3 first val of device3
I removed
super.service(req, res);
Then it worked fine for me
To join all lines into a string and remove new lines, I normally use :
with open('t.txt') as f:
s = " ".join([l.rstrip() for l in f])
This is the proper way to do it:
INSERT INTO destinationTable
SELECT * FROM sourceTable
I like the concept of grouping RadioButtons in WPF. There is a property GroupName
that specifies which RadioButton controls are mutually exclusive (http://msdn.microsoft.com/de-de/library/system.windows.controls.radiobutton.aspx).
So I wrote a derived class for WinForms that supports this feature:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Diagnostics;
using System.Windows.Forms.VisualStyles;
using System.Drawing;
using System.ComponentModel;
namespace Use.your.own
{
public class AdvancedRadioButton : CheckBox
{
public enum Level { Parent, Form };
[Category("AdvancedRadioButton"),
Description("Gets or sets the level that specifies which RadioButton controls are affected."),
DefaultValue(Level.Parent)]
public Level GroupNameLevel { get; set; }
[Category("AdvancedRadioButton"),
Description("Gets or sets the name that specifies which RadioButton controls are mutually exclusive.")]
public string GroupName { get; set; }
protected override void OnCheckedChanged(EventArgs e)
{
base.OnCheckedChanged(e);
if (Checked)
{
var arbControls = (dynamic)null;
switch (GroupNameLevel)
{
case Level.Parent:
if (this.Parent != null)
arbControls = GetAll(this.Parent, typeof(AdvancedRadioButton));
break;
case Level.Form:
Form form = this.FindForm();
if (form != null)
arbControls = GetAll(this.FindForm(), typeof(AdvancedRadioButton));
break;
}
if (arbControls != null)
foreach (Control control in arbControls)
if (control != this &&
(control as AdvancedRadioButton).GroupName == this.GroupName)
(control as AdvancedRadioButton).Checked = false;
}
}
protected override void OnClick(EventArgs e)
{
if (!Checked)
base.OnClick(e);
}
protected override void OnPaint(PaintEventArgs pevent)
{
CheckBoxRenderer.DrawParentBackground(pevent.Graphics, pevent.ClipRectangle, this);
RadioButtonState radioButtonState;
if (Checked)
{
radioButtonState = RadioButtonState.CheckedNormal;
if (Focused)
radioButtonState = RadioButtonState.CheckedHot;
if (!Enabled)
radioButtonState = RadioButtonState.CheckedDisabled;
}
else
{
radioButtonState = RadioButtonState.UncheckedNormal;
if (Focused)
radioButtonState = RadioButtonState.UncheckedHot;
if (!Enabled)
radioButtonState = RadioButtonState.UncheckedDisabled;
}
Size glyphSize = RadioButtonRenderer.GetGlyphSize(pevent.Graphics, radioButtonState);
Rectangle rect = pevent.ClipRectangle;
rect.Width -= glyphSize.Width;
rect.Location = new Point(rect.Left + glyphSize.Width, rect.Top);
RadioButtonRenderer.DrawRadioButton(pevent.Graphics, new System.Drawing.Point(0, rect.Height / 2 - glyphSize.Height / 2), rect, this.Text, this.Font, this.Focused, radioButtonState);
}
private IEnumerable<Control> GetAll(Control control, Type type)
{
var controls = control.Controls.Cast<Control>();
return controls.SelectMany(ctrl => GetAll(ctrl, type))
.Concat(controls)
.Where(c => c.GetType() == type);
}
}
}
The best solution, for me, is to wrap input [type="file"] in a wrapper, and add some jquery code:
$(function(){_x000D_
function readURL(input){_x000D_

var reader = new FileReader();_x000D_

}_x000D_
reader.readAsDataURL(input.files[0]);_x000D_

$("#image").change(function(){_x000D_

You are passing wrong mode to you view. Your view is looking for @model IEnumerable<Standings.Models.Teams>
and you are passing var model = tm.Name.ToList();
name list. You have to pass list of Teams.
You have to pass following model
var model = new List<Teams>();
model.Add(new Teams { Name = new List<string>(){"Sky","ABC"}});
model.Add(new Teams { Name = new List<string>(){"John","XYZ"} });
return View(model);
I would say using the data-
attribute to match the headers with the elements inside it. Fiddle : http://jsfiddle.net/GbRAZ/1/
A preview of the HTML alteration :
<tr class="header" id="header1">
<td colspan="2">Header</td>
</tr>
<tr data-for="header1" style="display:none">
<td>data</td>
<td>data</td>
</tr>
<tr data-for="header1" style="display:none">
<td>data</td>
<td>data</td>
</tr>
JS code :
$(".header").click(function () {
$("[data-for="+this.id+"]").slideToggle("slow");
});
EDIT:
But, it involves some HTML changes. so I dunno if thats what you wanted. A better way to structure this would be using <th>
or by changing the entire html to use ul, ol, etc
or even a div > span
setup.
Python don't have a great support for recursion because of it's lack of TRE (Tail Recursion Elimination).
This means that each call to your recursive function will create a function call stack and because there is a limit of stack depth (by default is 1000) that you can check out by sys.getrecursionlimit
(of course you can change it using sys.setrecursionlimit but it's not recommended) your program will end up by crashing when it hits this limit.
As other answer has already give you a much nicer way for how to solve this in your case (which is to replace recursion by simple loop) there is another solution if you still want to use recursion which is to use one of the many recipes of implementing TRE in python like this one.
N.B: My answer is meant to give you more insight on why you get the error, and I'm not advising you to use the TRE as i already explained because in your case a loop will be much better and easy to read.
You can also do this with ant contrib's if task.
<if>
<equals arg1="${condition}" arg2="true"/>
<then>
<copy file="${some.dir}/file" todir="${another.dir}"/>
</then>
<elseif>
<equals arg1="${condition}" arg2="false"/>
<then>
<copy file="${some.dir}/differentFile" todir="${another.dir}"/>
</then>
</elseif>
<else>
<echo message="Condition was neither true nor false"/>
</else>
</if>
Django provides it. You can use either:
{{ forloop.counter }}
index starts at 1.{{ forloop.counter0 }}
index starts at 0.In template, you can do:
{% for item in item_list %}
{{ forloop.counter }} # starting index 1
{{ forloop.counter0 }} # starting index 0
# do your stuff
{% endfor %}

Now I hope you can execute update-database successfully.
In Rails 3 and newer:
Rails.root
which returns a Pathname
object. If you want a string you have to add .to_s
. If you want another path in your Rails app, you can use join
like this:
Rails.root.join('app', 'assets', 'images', 'logo.png')
In Rails 2 you can use the RAILS_ROOT
constant, which is a string.

Generally mysql uses this date format 'Y-m-d H:i:s'
For the ones who are getting the error while requesting JSON data:
If your are requesting JSON data, the JSON might be too large and that what cause the error to happen.
My solution is to copy the request link to new tab (get
request from browser)
copy the data to JSON viewer online where you have auto parsing and work on it there.
If your button was made with Interface Builder, and you're changing the title in code, you can do this:

[self.button sizeToFit];
@BBKim pretty much gave the best answer, but it can just be done shorter. I'm surprised noone came up with it yet.
dat <- data.frame(x = rnorm(10, 30, .2), y = runif(10, 3, 5))
dat <- apply(dat, 2, function(x) (x - mean(x)) / sd(x))
In Rails 3.2.18, :decimal turns into :integer when using SQLServer, but it works fine in SQLite. Switching to :float solved this issue for us.
The lesson learned is "always use homogeneous development and deployment databases!"
You can do the following (which I find trivial, but its actually correct). For anyone trying to find how to initialize a two-dimensional array in TypeScript (like myself).
Let's assume that you want to initialize a two-dimensional array, of any type. You can do the following
const myArray: any[][] = [];
And later, when you want to populate it, you can do the following:
myArray.push([<your value goes here>]);
A short example of the above can be the following:
const myArray: string[][] = [];
myArray.push(["value1", "value2"]);
If you use Android default action bar then. If you change from java then some time show previous color.
Example
Then your action bar code inside "app_bar_main". So go inside app_bar_main.xml and just add Background.
Example
<?xml version="1.0" encoding="utf-8"?>
<android.support.design.widget.AppBarLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:theme="@style/AppTheme.AppBarOverlay">
<android.support.v7.widget.Toolbar
android:id="@+id/toolbar"
android:layout_width="match_parent"
android:layout_height="?attr/actionBarSize"
android:background="#33691e" <!--use your color -->
app:popupTheme="@style/AppTheme.PopupOverlay" />
</android.support.design.widget.AppBarLayout>
<include layout="@layout/content_main1" />
public
makes it accessible across other classes.
static
makes it uniform value across all the class instances.
final
makes it non-modifiable value.
So basically it's a "constant" value which is same across all the class instances and which cannot be modified.
With respect to your concern "What I don't understand is why people use that even if the constant will be used only in one place and only in the same class. Why declaring it? Why don't we just use the variable?"
I would say since it is a public field the constant value can also be used elsewhere in some other class using ClassName.value. eg: a class named Math may have PI as final static long value which can be accessed as Math.PI.
Presumably this would work:
IF(compliment = 'set' OR compliment = 'Y' OR compliment = 1, 'Y', 'N') AS customer_compliment
After trying out ngGrid, ngTable, trNgGrid and Smart Table, I have come to the conclusion that Smart Table is by far the best implementation AngularJS-wise and Bootstrap-wise. It is built exactly the same way as you would build your own, naive table using standard angular. On top of that, they have added a few directives that help you do sorting, filtering etc. Their approach also makes it quite simple to extend yourself. The fact that they use the regular html tags for tables and the standard ng-repeat for the rows and standard bootstrap for formatting makes this my clear winner.
Their JS code depends on angular and your html can depend on bootstrap if you want to. The JS code is 4 kb in total and you can even easily pick stuff out of there if you want to reach an even smaller footprint.
Where the other grids will give you claustrophobia in different areas, Smart Table just feels open and to the point.
If you rely heavily on inline editing and other advanced features, you might get up and running quicker with ngTable for instance. However, you are free to add such features quite easily in Smart Table.
Don't miss Smart Table!!!
I have no relation to Smart Table, except from using it myself.
Immediately after your execute statement you can have an if statement. For example
ResultSet rs = statement.execute();
if (!rs.next()){
//ResultSet is empty
}
Just simply open a batch file that contains this two lines in the same folder of your python script:
somescript.py
pause
Add something to track the length and allow you to do "checks" on whether the user is adding or subtracting text. This is currently untested but something similar to this should work (especially if you have a userform).
'add this to your userform or make it a static variable if it is not part of a userform
private oldLength as integer
Private Sub txtBoxBDayHim_Change()
if ( oldlength > txboxbdayhim.textlength ) then
oldlength =txtBoxBDayHim.textlength
exit sub
end if
If txtBoxBDayHim.TextLength = 2 or txtBoxBDayHim.TextLength = 5 then
txtBoxBDayHim.Text = txtBoxBDayHim.Text + "/"
end if
oldlength =txtBoxBDayHim.textlength
End Sub
Here is an interesting blog entry about numbers / limitations of Excel 2007. According to the author the new limit is approximately one million rows.
Sounds like you have a pre-Excel 2007 workbook open in Excel 2007 in compatibility mode (look in the title bar and see if it says compatibility mode). If so, the workbook has 65,536 rows, not 1,048,576. You can save the workbook as an Excel workbook which will be in Excel 2007 format, close the workbook and re-open it.
Hopefully this helps others in an enterprise setting looking for a solution. My solution after much tinkering was the following:
Follow the steps in the following link to install legacy browser extension and gpo settings: https://support.google.com/chrome/a/answer/3019558?hl=en&ref_topic=3062034
Enabled legacy browser redirect for "file://" through chrome gpo configuration Google Chrome -> Legacy Browser Support -> "Websites to open in alternative browser"
Configure gpo to also install extension: https://chrome.google.com/webstore/detail/enable-local-file-links/nikfmfgobenbhmocjaaboihbeocackld that redirects file:// links to bypass chrome file:// link block.
The extension opens the links which then triggers google chrome to open the link in internet explorer. The result is IE opens a window, then opens the file/folder for the user, then IE closes itself.
http://www.mindspill.org/962 seems to have a solution.
Essentially:
echo "This is the main body of the mail" | mail -s "Subject of the Email" [email protected] -- -f [email protected]
Simply specify whether you want the time to be greater, smaller, or equal to the time you want, using, respectively:
find . -cmin +<time>
find . -cmin -<time>
find . -cmin <time>
In your case, for example, the files with last edition in a maximum of 5 minutes, are given by:
find . -cmin -5
You can use this command to repeat your command 10 times or more
for i in {1..10}; do **your command**; done
for example
for i in {1..10}; do **speedtest**; done

To summarize Laryx Decidua's answer:
define and use a function like the following
plot.with.errorbars <- function(x, y, err, ylim=NULL, ...) {
if (is.null(ylim))
ylim <- c(min(y-err), max(y+err))
plot(x, y, ylim=ylim, pch=19, ...)
arrows(x, y-err, x, y+err, length=0.05, angle=90, code=3)
}
where one can override the automatic ylim, and also pass extra parameters such as main, xlab, ylab.
Using Firebase Console you can send message to all users based on application package.But with CURL or PHP API its not possible.
Through API You can send notification to specific device ID or subscribed users to selected topic or subscribed topic users.

Wrap the menu contents with another div:
<div id="floatingMenu">
<div>
<a href="http://www.google.com">Test 1</a>
<a href="http://www.google.com">Test 2</a>
<a href="http://www.google.com">Test 3</a>
</div>
</div>
And the CSS:
#floatingMenu {
clear: both;
position: fixed;
width: 100%;
height: 30px;
background-color: #78AB46;
top: 5px;
}
#floatingMenu > div {
margin: auto;
text-align: center;
}
And about your page below the menu, you can give it a padding-top as well:
#content {
padding-top: 35px; /* top 5px plus height 30px */
}
Whenever you change a class in your script, you could use a trigger
to raise your own event.
$(this).addClass('someClass');
$(mySelector).trigger('cssClassChanged')
....
$(otherSelector).bind('cssClassChanged', data, function(){ do stuff });
but otherwise, no, there's no baked-in way to fire an event when a class changes. change()
only fires after focus leaves an input whose input has been altered.
$(function() {_x000D_
var button = $('.clickme')_x000D_
, box = $('.box')_x000D_
;_x000D_
_x000D_
button.on('click', function() { _x000D_
box.removeClass('box');_x000D_
$(document).trigger('buttonClick');_x000D_
});_x000D_
_x000D_
$(document).on('buttonClick', function() {_x000D_
box.text('Clicked!');_x000D_
});_x000D_
});
_x000D_
.box { background-color: red; }
_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div class="box">Hi</div>_x000D_
<button class="clickme">Click me</button>

Hint: The STRINGIZE
macro above is cool, but if you make a mistake and its argument isn't a macro - you had a typo in the name, or forgot to #include
the header file - then the compiler will happily put the purported macro name into the string with no error.
If you intend that the argument to STRINGIZE
is always a macro with a normal C value, then
#define STRINGIZE(A) ((A),STRINGIZE_NX(A))
will expand it once and check it for validity, discard that, and then expand it again into a string.
It took me a while to figure out why STRINGIZE(ENOENT)
was ending up as "ENOENT"
instead of "2"
... I hadn't included errno.h
.
To push branches and tags (but not remotes):
git push origin 'refs/tags/*' 'refs/heads/*'
This would be equivalent to combining the --tags
and --all
options for git push
, which git does not seem to allow.
Editing or overriding the row in Twitter bootstrap is a bad idea, because this is a core part of the page scaffolding and you will need rows without a top margin.
To solve this, instead create a new class "top-buffer" that adds the standard margin that you need.
.top-buffer { margin-top:20px; }
And then use it on the row divs where you need a top margin.
<div class="row top-buffer"> ...
curl command:
curl -X PUT http://127.0.0.1:8080/api/xxx ...
-H 'content-type: multipart/form-data; boundary=----xxx' \
-F taskStatus=1
python requests - More complicated POST requests:
updateTaskUrl = "http://127.0.0.1:8080/api/xxx"
updateInfoDict = {
"taskStatus": 1,
}
resp = requests.put(updateTaskUrl, data=updateInfoDict)
curl command:
curl -X POST http://127.0.0.1:8080/api/xxx ...
-H 'content-type: multipart/form-data; boundary=----xxx' \
-F file=@/Users/xxx.txt
python requests - POST a Multipart-Encoded File:
filePath = "/Users/xxx.txt"
fileFp = open(filePath, 'rb')
fileInfoDict = {
"file": fileFp,
}
resp = requests.post(uploadResultUrl, files=fileInfoDict)
that's all.
Not my fiddle, but http://jsfiddle.net/maxisam/QrCXh/ shows the difference. The key piece is:
scope:{
/* NOTE: Normally I would set my attributes and bindings
to be the same name but I wanted to delineate between
parent and isolated scope. */
isolatedAttributeFoo:'@attributeFoo',
isolatedBindingFoo:'=bindingFoo',
isolatedExpressionFoo:'&'
}
Just wanted to add some info that, we can check this info whether git pull
automatically refers to any branch or not.
If you run the command, git remote show origin
, (assuming origin as the short name for remote), git shows this info, whether any default reference exists for git pull
or not.
Below is a sample output.(taken from git documentation).
$ git remote show origin
* remote origin
Fetch URL: https://github.com/schacon/ticgit
Push URL: https://github.com/schacon/ticgit
HEAD branch: master
Remote branches:
master tracked
dev-branch tracked
Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (up to date)
Please note the part where it shows, Local branch configured for git pull.
In this case, git pull
will refer to git pull origin master
Initially, if you have cloned the repository, using git clone, these things are automatically taken care of. But if you have added a remote manually using git remote add, these are missing from the git config. If that is the case, then the part where it shows "Local branch configured for 'git pull':", would be missing from the output of git remote show origin
.
The next steps to follow if no configuration exists for git pull
, have already been explained by other answers.
And it's maybe also handy to know that BigTable is not a relational database (like MySQL) but a huge (distributed) hash table which has very different characteristics. You can play around with (a limited version) of BigTable yourself on the Google AppEngine platform.
Next to Hadoop mentioned above there are many other implementations that try to solve the same problems as BigTable (scalability, availability). I saw a nice blog post yesterday listing most of them here.
it declares that the type is nullable.
One more method is to Define the Layout inside the View:
@{
Layout = "~/Views/Shared/_MyAdminLayout.cshtml";
}
More Ways to do, can be found here, hope this helps someone.
