] | To achieve this, you should read up on the basic concepts of jQuery, in particular the jQuery [click](http://api.jquery.com/click/) and [html](http://api.jquery.com/html/)/[text](http://api.jquery.com/text/) functions.
In the most basic form, you would use it something like this:
```
$('#myNavLink').click(function(){
$('#myContentArea').text("This is the new content text");
});
``` | This is a very broad question and has answers all over the internet; however, to get you started you will want to check out the following syntax:
```
var value = '<p>Here is my new content that came from my database, fetched using Ajax & jQuery!</p>';
$('#mydiv').html(value);
```
Mind you that the code above is very destructive meaning that it will completely replace all content.
Good luck! |

] | As I said in my comment on the question, this question is too broad and I expect it will get closed by the community. But I thought I'd offer a couple of pointers:
1. You can trigger a function call when an element is clicked by having jQuery hook up a `click` handler on that element. You need to be able to tell jQuery which element you're talking about, which you can do with any CSS selector. You might use an `id` (although `id`s are not necessarily the best choice in general). For example:
```
$("#foo").click(function() {
alert("Hi there");
});
```
...will hook up that function to the `click` event on the element with the `id` `"foo"`.
2. You can load content into an element using the `html` function (for content you specify in a string in the code) or the `load` function (for content you load from your server on-demand), again by having jQuery look up the element, and then acting on it:
```
$("#foo").html("New content");
$("#foo").load("/path/to/new/content/on/server");
```
The [jQuery API docs](http://api.jquery.com) are a good starting point, and there are any number of online tutorials and blogs. Good luck with it. | This is a very broad question and has answers all over the internet; however, to get you started you will want to check out the following syntax:

] | First let's solve an easier integral that doesn't have the denominator squared, namely:$$y(t)=\int\_0^\infty \frac{\cos(tx)}{\color{blue}{1+x^2}}dx=\int\_0^\infty \cos(tx){\color{blue}{\int\_0^\infty \sin y e^{-xy}dy}}dx$$
$$={\int\_0^\infty}\sin y{\color{red}{\int\_0^\infty \cos(tx)e^{-xy}dx}}dy=\int\_0^\infty \frac{{\color{red}y}\sin y}{{\color{red}{t^2+y^2}}}dy $$
$$\overset{y=tx}=\int\_0^\infty \frac{x\sin(tx)}{1+x^2}dx=-y'(t)\Rightarrow \frac{y'(t)}{y(t)}=-1 \Rightarrow y(t)=c\cdot e^{-t}$$
$$y(0)=\int\_0^\infty \frac{dx}{1+x^2}=\frac{\pi}{2}\Rightarrow c=\frac{\pi}{2}\Rightarrow y(t)=\frac{\pi}{2}e^{-t}$$
$$y(t)\overset{tx=z}=t\int\_0^\infty\frac{\cos z}{t^2+z^2}dz\Rightarrow\boxed{\int\_{-\infty}^\infty\frac{\cos x}{t^2+x^2}dx=\frac{\pi}{t}e^{-t},\ t>0}$$
---
Now in order to find the desired integral, we will differentiate under the integral sign, with respect to $t$ then divide by $-2t$, since:
$$\frac{d}{dt}\int\_{-\infty}^\infty\frac{\cos x}{t^2+x^2}dx=-2t\int\_{-\infty}^\infty\frac{\cos x}{(t^2+x^2)^2}dx=\frac{d}{dt}\left(\frac{\pi}{t}e^{-t}\right)$$
$$\Rightarrow \int\_{-\infty}^\infty\frac{\cos x}{(t^2+x^2)^2}dx=-\frac{1}{2t}\frac{d}{dt}\left(\frac{\pi}{t}e^{-t}\right)=\frac{\pi(t+1)}{2t^3}e^{-t},\ t>0$$ | Another way to do it is to note that$$\frac{1}{x^2+t^2}=\frac{1}{2it}\left(\frac{1}{x-it}-\frac{1}{x+it}\right)\implies\frac{1}{(x^2+t^2)^2}=\frac{-1}{4t^2}\left(\frac{1}{(x-it)^2}+\frac{1}{(x+it)^2}+\frac{i}{t}\left(\frac{1}{x-it}-\frac{1}{x+it}\right)\right).$$The $e^{ix}$ in $\cos x$ doesn't diverge when $x=i\infty$, so the $\Im x\ge0$ semicircle contains a pole $it$ contributing$$\frac{-i\pi}{2t^2}\left.\left(\frac{d}{dx}e^{ix}+\frac{i}{t}e^{ix}\right)\right|\_{x=it}=\frac{-i\pi}{2t^2}\left(ie^{-t}+\frac{i}{t}e^{-t}\right)=\frac{\pi(t+1)}{2t^3e^t}.$$ |

] | 1. Your page must be stateful in order to change it state. Stateless widget are static, you can use them when your Widgets don't change and the user doesn't interact with the screen.
2. You have to call the setState() method, so your page know's something has changed.
3. Later, if you desire to evolve your code, use state management (MobX,GetX, Cubit, RxDart) instead of setStates. When you use setState, all the widgets under the widget-tree reload, so it consumes more CPU and GPU.
Try something like this:

if you have some problem, give me a feedback. | I don't know exactly how do you want to use it. But I will give my solution as I understood the issue.
First, change StatelessWidget to StatefulWidget.
Then you can define the position variable inside the HomeScreen class and set the current position to.
Then send this variable as a parameter to the buildAppbar function:
AppBar buildAppBar(context, dynamic currentPos){...}
the variable currentPos is for storing the value got from async function named getCurrentPosition.
The Text widget accepts only String data type, so you can use currPos.toString() method or using it as you prefer.
To get the value of current position from the asynchronous function named getCurrentPosition and assigned it to the position variable
when the widget being created and then send it to the buildAppbar function, you can do the following in your code.
\*sorry
see the code in the image.
I wrote it in mobile because I don't have lap now and when I post the answer an error appears in code formatting. So I will tack a screenshot for code and add it here.

38,125,599 | I really want to know, how can I click a button inside a Bootstrap modal after I've open it by clicking its link:
```
<a href="#" data-toggle="modal" data-target="#myid">

Buttons have ids', so I think I can click the button using **js**, but I don't really know how to deal with this.
Could I use a function such as `$("#buttonid").click();` in the `data-target` after the modal call?

96,557 | In Dybjer's *Inductive Families* the author present a method to derive an eliminator/induction principle for every inductive family of types.
In particular for the type of finite lists, namely
$$List' \colon (A \colon set) (n \colon N) set$$
we get the eliminator
$$\begin{align\*}
listrec' \colon &(A \colon set)\\
& (C \colon (a \colon N)(c \colon List'\_A n)set) \\
& (e\_1 \colon C(0,nil'\_A)\\
& (e\_2 \colon (b\_1 \colon N)(b\_2 \colon A)(u \colon List'\_A(b\_1))(v \colon C(b\_1,u))C(s(b\_1),cons'\_A(b\_1,b\_2,u)))\\
& (a \colon N) \\
& (c \colon List'\_A(a)) \\
& C(a,c)\ .
\end{align\*}$$
From what I get from this eliminator we should be able to provide any possible operation using finite lists.
Now my question is
>
> how do we get the classical *destructor* $$tail \colon (A \colon set)(n \colon N)(List'\_A(s(n))) List'\_A n$$

I am totally lost on how to approach this problem since the eliminator seems to be able to provide just function defined on the whole family $List'\_A(n)$ and not on the sub-family $List'\_A(s(n))$.

The typical trick in this situation is to pick a `C` such that you can pretend you are defining a function on the whole family when, in fact, you're only focusing on the sub-family you care about thanks to equality constraints.
Let me be more concrete:
If you pick `C(n, xs) = (m:N) -> n = s(m) -> List'_A(m)` then you can define a generalised `gtail` by using `listrec'`, and derive `tail` as a corollary.
```
gtail : (A:set) (n:N) (xs : List'_A(n)) -> C(n, xs)
gtail A = listrec' A C
contradiction -- of type: (m:N) -> 0 = s(m) -> List'_A(m)
(\ _ _ u _ -> u)
tail : (A:set) (n:N) -> List′A (s(n)) -> List′An
tail A n xs = gtailn A (s(n)) xs n refl
``` | What follows is just a little modification of the idea proposed in the accepted answer, nevertheless I think it can be of interest to other readers.
Here's a way to build tail
We can consider the predicate
$P \colon (A\colon set)(n \colon N)(l \colon List'\_A n)set$ defined (by recursion on natural numbers) as the only type family such that
$$\begin{align\*}
P(A,0,l)&= 1\\
P(A, s(n),l) &= List'\_A (n)
\end{align\*}$$
where $1$ is the unit type with only term $()$.
If we let
$$e\_1 = () \colon 1= P(A,0,nil')$$
and
$$e\_2=\lambda n \colon N.\lambda x \colon A.\lambda xs \colon List'\_A n. \lambda p \colon P(A,n,xs). xs \colon (n \colon N)(x\colon A)(xs \colon List'\_A n)(p \colon P(A,n,xs))\underbrace{List'\_A(n)}\_{=P(A,s(n),cons'\_A(n,x,xs))}$$
we get
$almostTail = (\lambda A \colon set) listrec'(A,P(A),e\_1,e\_2) \colon (A \colon set)(n \colon N)(l \colon List'\_A(n))P(A,n,l)$
which by the reduction principle is such that
$$almostTail(A,s(n),cons'\_A(n,x,xs))=e\_2(n,x,xs,almostTail(A,n,xs))=xs\ .$$
So we get
$$tail' \colon (A\colon set)(n\colon N)(l \colon List'\_A(s(n)))\underbrace{P(A,s(n),l)}\_{List'\_A(n)}$$
by letting
$$tail'(A,n,l) = almostTile(A,s(n),l)\ .$$
**Note**: the only difference between gallais' example and mine is that instead of adding an hypothesis in the predicate to pass to $listrec'$ I have used a predicate with a *don't care value* for the case $n=0$.
In this case too we basically build a function defined on all the lists, with the desired behaviour in the case of interest (i.e. not empty lists), and then consider the specialized/restricted function for the sub-family of types we are interested in. |
1,025,803 | Given the follwing class - I would like to know which of the both members is abstract:

] | A property is actually some 'syntactic sugar', and is implemented by 2 methods: a getter method and a setter method.
So, I think that you should be able to determine if a property is abstract by checking if the getter and/or setter are abstract, like this:
```
PropertyInfo pi = ...
if( pi.GetSetMethod().IsAbstract )
{
}
```
And, AFAIK, a field cannot be abstract. ;) | First off: fields can't be abstract, since all there is to them is the field itself.
Next we note that properties are (in a loose sense!) actually get\_/set\_ methods under the hood.
Next we check what *does* have an `IsAbstract` property, and see that `MethodBase` (and so `MethodInfo`) does.
Finally we remember/know/find out that a `PropertyInfo` has `GetGetMethod()` and `GetSetMethod()` methods that return `MethodInfo`s, and we're done, except for filling in the messy details about inheritance and so forth. |
32,211,793 | I am really having trouble wrapping my head around the deferred() method inside jquery. I've spent several hours reading the documentation, but I still don't fully understand what I'm doing.
My basic problem is, I have a series of functions (not ajax calls) that I want to run in sequence, but stop all processes if there is an error in any of them.
Here is how far I've gotten (I've stripped out a bunch of unneeded code and just left the basic idea)
```
//The module var myModule = (function() {
//Defaults
var vOne;
var VTwo;
var deferred = $.Deferred();
//Private method
var _myPrivateFunction1 = function(userID) {
if(userID >= 10) {
//All is good, set var vOne to true and run next function
vOne = true;
return deferred.promise();
} else {
//User is not allowed, stop everything else and show the error message
return deferred.reject();
}
}
var _myPrivateFunction2 = function() {
if(vOne === true) {
//Ok we can keep going
return deferred.promise();
} else {
//again stop everything and throw error
return deferred.reject();
}
};
var _myPrivateFunction3 = function(element) {
//...and so on
};
var _errorMsgFunction = function(msg) {
$.log("There was an error: " + msg);
return false;
};
//Public method
var myPublicFunction = function(element,call) {
//element is jquery object passed through user "click" event
var userID = element.data('id')
var userAction = element.data('action');
//Now... i want to fire _myPrivateFunction1, _myPrivateFunction2, _myPrivateFunction3 in sequence and STOP all processes, and run
// _errorMsgFunction if there is an error in any of them.
//This is how far I've gotten...
_myPrivateFunction1(userID).then(_myPrivateFunction2(userAction), _errorMsgFunction("Error in _myPrivateFunction2")).then(_myPrivateFunction3(element),_errorMsgFunction("Error in _myPrivateFunction3")).fail(_errorMsgFunction("Error in _myPrivateFunction1"));
};
// Public API
return {
myPublicFunction: myPublicFunction
};
})();
```
So right now I keep getting "Error in \_myPrivateFunction2" (I'm forcing this error for testing purposes), but the other functions after continue to fire...They don't stop. What am I missing here? | 2015/08/25 | [

] | You cannot share deferred objects. You should create a different promise from a deferred for each function.
Here is some very simple example, using sycnhronus functions for the sake of simplicity, although promises are meant to be used with asynchronous functions:
```
var func1 = function(arg){
var dfd = jQuery.Deferred();
if (arg === 0) {
dfd.resolve('func1 Ok');
} else {
dfd.reject('func1 arg != 0');
}
return dfd.promise();
}
var func2 = function(arg){
var dfd = jQuery.Deferred();
if (arg === 0) {
dfd.resolve('func2 Ok');
} else {
dfd.reject('func2 arg != 0');
}
return dfd.promise();
}
var func3 = function(arg){
var dfd = jQuery.Deferred();
if (arg === 0) {
dfd.resolve('func3 Ok');
} else {
dfd.reject('func3 arg != 0');
}
return dfd.promise();
}
```
If the functions does not depend on other to do their processing, we can do it in parallel using `jQuery.when`
```
// Parallel processing
jQuery.when(func1(1), func2(0), func3(0)).then(function(res1, res2, res3){
console.log(res1, res2, res3);
}).fail(function(reason){
console.error(reason); // will fail with reason func1 arg != 0
});
```
If it is a sequence processing (as I undertood your problem is), you should do:
```
// Sequential processing
func1(0).then(function(res1){
return func2(res1);
}).then(function(res2){
return func3(res2);
}).then(function(res3){
// everything ran ok, so do what you have to do...
}).fail(function(reason){
console.log(reason);
});
```
The code above will fail with reason:
```
> func2 arg != 0
```
If you have mixed parallel and sequential processing to do, then you should mix both approaches.
---
Disclaimer
----------
As in my example, if `func1` or `func2` have side effects, they will not be undone within `fail()` by themselves.
The best practice is to only have side effects when you are absolutely sure that everything went ok, that is, inside the last `then()` call. | You will need a separate `$.deferred()` inside each of your functions, because you want to return unique promise for each function.
```
//Private method
var _myPrivateFunction1 = function(userID) {
var deferred = $.Deferred();
if(userID >= 10) {
//All is good, set var vOne to true and run next function
vOne = true;
deferred.resolve();
} else {
//User is not allowed, stop everything else and show the error message
deferred.reject();
}
return deferred.promise();
}
```
Then your public function should work. |

] | * Dont call `drawPiece()` from your constructor for what reason? I think [`repaint()`](http://docs.oracle.com/javase/7/docs/api/java/awt/Component.html#repaint%28%29) might be what you need.
* dont use `getGraphics()` as it wont be initialized yet until the panel is added and first repaint is done if im not mistaken.
* Also never forget to honor paint chain and have `super.paintComponent(..)` as your first call in your overridden `paintComponent(..)` method of panel.
* Rather extend `JPanel` and not `JComponent`
I think you meant to call `drawPiece()` in `paintComponent(..)` in which place you should just pass the `Graphic`s object to `drawPiece()` from `paintComponent(..)` like so:
```
public class Piece extends JPanel{
public Piece(char color, char Type, int posX, int posY){
// each piece assigned a PK on creation, beginning sequentially from top left
// and looping back to the beginning of each row
....
// P = pawn, K = knight, R = Rook, B = Bishop, Q = Queen,
//S = king (can't reuse K, so we use S instead (from Shah, the historical name))
....
nextID ++;
Chess.position[posX][posY] = pieceID;
repaint();
}
@Override
public void paintComponent(Graphics g){
super.paintComponent(g);
drawPiece(g);
}
public void drawPiece(Graphics g){
g.drawImage(piece.getImage(),(locx*Chess.SQUARE_WIDTH),(locy*Chess.SQUARE_HEIGHT),null);
}
}
```
Other suggestions:
* Create `JFrame` and other Swing components on [EDT](http://docs.oracle.com/javase/tutorial/uiswing/concurrency/dispatch.html) by wrapping UI creation code in
```
SwingUtilities.invokeLater(new Runnable(){
@Override
public void run() {
//create ui here
}
});
```
* Dont call `setSize(...)` on `JFrame`
rather override `JPanel` `getPreferredSize()` and return an appropriate size which fits components etc than you can remove `setSize` call on `JFrame` and call `pack()` on `JFrame` instance before setting visible | It seems like your variable `board` is not initialized yet. You need to call `setCanvas()` first to initialize it, then you can call `drawPiece()`. |

] | Elegant solution for a two characters alphabet
----------------------------------------------
Since you only have two letters in your alphabet, an elegant solution could be to use binary decomposition of integers (`a` represents a binary `0` and `b` represents a `1`). Here's the algorithm you could implement:

General solution for any alphabet
---------------------------------
You can generalize the above solution by counting in base `k` (where `k` is the size of the alphabet) instead of 2. It could look like this:
```
public static void main(String[] args) {
listWords(new char[]{ 'e', 'z', 'f' }, 3);
}
private static void listWords(char[] alphabet, int maxWordLength) {
Arrays.sort(alphabet);
int base = alphabet.length;
int wordLength = 1;
int current = 0;
int max = (int) Math.pow(base, wordLength) - 1;
while (wordLength <= maxWordLength) {
System.out.println(makeWord(alphabet, current, wordLength));
if (current < max) current++;
else {
wordLength++;
current = 0;
max = (int) Math.pow(base, wordLength) - 1;
}
}
}
private static String makeWord(char[] alphabet, int current, int wordLength) {
int base = alphabet.length;
StringBuilder sb = new StringBuilder();
for (int i = 0; i < wordLength; i++) {
sb.append(alphabet[current % base]);
current /= base;
}
return sb.reverse().toString();
}
```
Output:
```
e
f
z
ee
ef
ez
fe
ff
fz
ze
zf
zz
eee
eef
eez
efe
eff
efz
eze
ezf
ezz
fee
fef
fez
ffe
fff
ffz
fze
fzf
fzz
zee
zef
zez
zfe
zff
zfz
zze
zzf
zzz
```
Note that this implementation will be much slower than the previous one because divisions and `Math.pow` are slow operations compared to binary shifts.
Non-arithmetic general solution
-------------------------------
The logic of counting in base `k` can also be implemented manually. It might be more efficient but will definitely take more time and code. Below is the general idea of the algorithm:
* you start by filling the string with the lowest value
* then, you increment the value of the last character
* when you can't increment anymore, you reset all the characters at the right of your current position
* you increment your position, and increment the value of this position
* you start all over again doing the same thing from the right of the string
What's cool about this is that if you use a `StringBuilder`, you can minimize the number of array allocation to only one per iteration since each state of the `StringBuilder` can be reached in a few operations (proportional the the length of the string) from the previous state. | By following @Dici's approach, I've written this code that specifically solves my problem.
```
public class SigmaStar {
//max length of word, just to limit the execution
//change it with your own value
private static final int MAX_LENGTH = 4;
public static void main(String[] args) {
int wordLength = 0;
int current = 0;
int max = (1 << wordLength) - 1;
while (wordLength <= MAX_LENGTH) {
System.out.println("'"+makeWord(current, wordLength)+"'");
if (current < max) current++;
else {
wordLength++;
current = 0;
max = (1 << wordLength) - 1;
}
}
}
private static String makeWord(int current, int wordLength) {
StringBuilder sb = new StringBuilder();
for (int i = 0; i < wordLength; i++) {
sb.append((char) ((current % 2) + 'a'));
current >>= 1;
}
return sb.reverse().toString();
}
}

11,567,134 | I am using several SharedPreferences to store data in my app.
Some preferences are used in a lot of activites.
I know that the SharedPreferences are internally backed by a map for fast read-access and written to sdcard when settings are changed.

1. Instantiate it in every activity using the activity context.
2. Instantiate it in every activity, but using the application context.
3. Put it in e.g. the Application class and instantiate it only once there, similar to a singleton.

14,896,607 | My application is navigation based and mainly runs in portrait orientation, But one view controller supports both portrait and landscape orientation. Now the problem is, When I push the new viewcontroller from landscape view controller, the new view controller is also pushed in landscape mode though i want it in portrait mode.
Also when I pop view controller from landscape controller then the poped view controller is getting displayed in portrait mode.
I don't know what is wrong with my code.
Here is the my code snippet and information used for these orientation support.
In info.plist file I kept support for all orientation but portrait upsidedown.
I have also added category for navigation controller category as below.

-(BOOL)shouldAutorotate
{
return [[self.viewControllers lastObject] shouldAutorotate];
}
-(NSUInteger)supportedInterfaceOrientations
{
return [[self.viewControllers lastObject] supportedInterfaceOrientations];
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation
{
return [[self.viewControllers lastObject] preferredInterfaceOrientationForPresentation];
}
@end
```
I have also created a UIViewController subclass that acts as superclass for all classes. Here are the orientation methods for super class.
```
@implementation ParentViewController
- (BOOL)shouldAutorotate{
return NO;
}
- (NSUInteger)supportedInterfaceOrientations{
return UIInterfaceOrientationMaskPortrait;
}
-(BOOL)shouldAutorotateToInterfaceOrientation:(UIInterfaceOrientation)toInterfaceOrientation{
return (toInterfaceOrientation == UIInterfaceOrientationPortrait);
}
- (UIInterfaceOrientation)preferredInterfaceOrientationForPresentation{
return UIInterfaceOrientationPortrait;
}
@end
```
And the orientation methods controller that supports landscape are as below.
```
@implementation LandscapeController
#pragma mark -
#pragma mark Orientation Methods

- (NSUInteger)supportedInterfaceOrientations{

} else { // end of phrase
//console.log("end:", terms[i]);

items.push(buffer.join(" "));
buffer = [];

const data = new FormData()
photos.forEach((element, i) => {
const newFile = {

```
import { Events } from 'ionic-angular';
@ViewChild(Slides) slides: Slides;
constructor(public events: Events) {
events.subscribe('slider:slideTo', (index) => {
if(this.slides) {
this.slides.slideTo(index, 500);
} else {
console.log('Tried to modify the slides but they were not loaded yet');
}
});
}
```
And in your `app.component.ts` file, just publish that event when needed:
```
import { Events } from 'ionic-angular';
constructor(public events: Events) {}
changeCurrentSlide(index) {
this.events.publish('slider:slideTo', index);
}
``` | You could just insert a slider component on that page too?
If you want the slider component to be defined only in the app component you could:
1.: emit an event in the home.ts which would be listened to in the app.component.
2.: make a slider.service.ts which you inject in your he component and in your app.component or directly in your slider.component(if it's not third party). The slider service could have a public eventemitter which u'd use or a rxjs Subject. This way you can notify a component from within another component. |

I can extract the other user's activity in term of addition and deletion at specified location in a textarea.
I will then transmit the location, along with the action to the other document. There I need to carry out the required change at the sent coordinate. I have searched and found enough ways to set the caret location and insert or delete text at the current caret location, but the problem is that the caret of the document moves to the location at which I make the change.
I don't want that, I want to have two carets, one each for the two users. Transmit their changes to each other documents and make the changes at their respective locations, while showing two different carets.
I just need to know if there are certain libraries that I can use, or even if I have to make this on my own, then how and where do I start.

] | You could mimic a caret with a special character and do the regex to insert the partner text and move his caret, and you can use the real one. This is the simplest design I can think.
To get the idead, you could use the pipe `|` as a artificial caret. but this would easily conflict with user insert a pipe, to avoid this you can use sort of uncommon combination, or find some unicode character to act as a caret.
A real solution but way more complicated is not use a textarea, and use a DIV. this means that you need to handle all the key events and insert the character pressed manually to the document, and register the cursor position. But this way you can insert how many carets you want not just 2, something like this `<span class="caret1"></span>` you can make it blink, style with css, have diferent color for each caret, etc. | Have you tried Draft.js, from facebook ? <https://facebook.github.io/draft-js/>

```

So `c` can be 0 and pass to the next step where you pass `c-1` to the index, which works because python doesn't mind negative indexes but still false (`coins[-1]` yields `25`), so your solution sometimes prints 1 combination too much.
I've rewritten your algorithm with recursive and stack approaches:
Recursive (fixed, no need for `c` at init thanks to an internal recursive method, but still overflows the stack):
```
coins = [1,5,10,25]
def change(n):
def change_recurse(n, c):
if n == 0:
return 1
if n < 0:
return 0;
if c <= 0:
return 0
return change_recurse(n, c - 1) + change_recurse(n - coins[c - 1], c)
return change_recurse(n,len(coins))
```
iterative/stack approach (not dynamic programming), doesn't recurse, just uses a "stack" to store the computations to perform:
```
def change2(n):
def change_iter(stack):
result = 0
# continue while the stack isn't empty
while stack:
# process one computation
n,c = stack.pop()
if n == 0:
# one solution found, increase counter
result += 1
if n > 0 and c > 0:
# not found, request 2 more computations
stack.append((n, c - 1))
stack.append((n - coins[c - 1], c))
return result
return change_iter([(n,len(coins))])
```
Both methods return the same values for low values of `n`.
```
for i in range(1,200):
a,b = change(i),change2(i)
if a != b:
print("error",i,a,b)
```
the code above runs without any error prints.
Now `print(change2(1000))` takes a few seconds but prints `142511` without blowing the stack. |

For touch event "hit" testing, you generally don't want to use the raw geometry. Generally use some simple proxy geometry, which can be transformed in software on the CPU. | Maybe you should try this:

] | In order to help you migrate from beta4 to beta5, these are the following steps it took me, based on the research/findings.
Environment
===========
* PowerShell run: `$env:DNX_FEED="https://www.nuget.org/api/v2"`
* PowerShell run: `dnvm install 1.0.0-beta5`
* PowerShell run: `dnvm use 1.0.0-beta5 -p` (*not sure if its needed however i had to*)
Project
=======
* Open global.json and update sdk to 1.0.0-beta5 should look like this:
```
{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-beta5"
}
}
```
* Open project.json:
+ Updated dependencies versions from beta4 to beta5
+ Change **Configuration** dependency from:
```
"Microsoft.Framework.ConfigurationModel.Json": "1.0.0-beta4"
```
to
```
"Microsoft.Framework.Configuration": "1.0.0-beta5",
"Microsoft.Framework.Configuration.Json": "1.0.0-beta5"
```
+ Remove `Microsoft.VisualStudio.Web.BrowserLink.Loader`
+ Rename `_GlobalImport.cshtml` to `_ViewImports.cshtml`
Startup.cs changes
------------------
* Change Configuration breaking changes
+ Change namespace from `using Microsoft.Framework.ConfigurationModel;` to `using Microsoft.Framework.Configuration;`
+ Change `Configuration.GetSubKey` to `Configuration.GetConfigurationSection`
+ Change CTOR to:
```
public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
// Setup configuration sources.
var configBuilder = new ConfigurationBuilder(appEnv.ApplicationBasePath)
.AddJsonFile("config.json")
.AddEnvironmentVariables();
Configuration = configBuilder.Build();
}
```
+ Remove `app.UseBrowserLink();`
Project DNU CMDs
================
* Open PowerShell within **app root**
* Run `dnu restore`
* Run `dnu build`
* Closing and reopening VS at this point helps sometimes.
Myself found it quite difficult to upgrade an existing project, couldn't find all steps required all together.
Hope it helps! | In case anyone is wondering how to update to ASP.NET 5 Beta 7, I found it useful to download the latest ASP.NET and Web Tools updates for Visual Studio 2015 and then create a new ASP.NET 5 project in Visual Studio.
This will create a Beta 7 project with the project structure, code and referenced dependencies for you. You can then use this as a guide to upgrade any existing older Beta projects.
For example here what my project.json looks like using all the Beta 7 dependencies:
```

My project work in beta6 after that, maybe there are other things to do. | This is the thing:
You updated the DNX from beta4 to beta5, and you want to run an MVC6 template inside Visual Studio RC (whose templates were built around beta4).
In the first place, `"Microsoft.Framework.Configuration.Json"` doesn't exist in beta5 anymore. (you should definitely see this: <https://github.com/aspnet/announcements/issues?q=milestone%3A1.0.0-beta5> - breaking changes from beta4 to beta5).
In order to see that your DNX was updated properly, build a new empty web project and simply add MVC/WebAPI (simple cases to check that it works).
I haven't tried to run the MVC template yet, but I will try and come back to you. |

] | In order to help you migrate from beta4 to beta5, these are the following steps it took me, based on the research/findings.
Environment
===========
* PowerShell run: `$env:DNX_FEED="https://www.nuget.org/api/v2"`
* PowerShell run: `dnvm install 1.0.0-beta5`
* PowerShell run: `dnvm use 1.0.0-beta5 -p` (*not sure if its needed however i had to*)
Project
=======
* Open global.json and update sdk to 1.0.0-beta5 should look like this:
```
{
"projects": [ "src", "test" ],
"sdk": {
"version": "1.0.0-beta5"
}
}
```
* Open project.json:
+ Updated dependencies versions from beta4 to beta5
+ Change **Configuration** dependency from:
```
"Microsoft.Framework.ConfigurationModel.Json": "1.0.0-beta4"
```
to
```
"Microsoft.Framework.Configuration": "1.0.0-beta5",
"Microsoft.Framework.Configuration.Json": "1.0.0-beta5"
```
+ Remove `Microsoft.VisualStudio.Web.BrowserLink.Loader`
+ Rename `_GlobalImport.cshtml` to `_ViewImports.cshtml`
Startup.cs changes
------------------
* Change Configuration breaking changes
+ Change namespace from `using Microsoft.Framework.ConfigurationModel;` to `using Microsoft.Framework.Configuration;`
+ Change `Configuration.GetSubKey` to `Configuration.GetConfigurationSection`
+ Change CTOR to:
```
public Startup(IHostingEnvironment env, IApplicationEnvironment appEnv)
{
// Setup configuration sources.
var configBuilder = new ConfigurationBuilder(appEnv.ApplicationBasePath)
.AddJsonFile("config.json")
.AddEnvironmentVariables();
Configuration = configBuilder.Build();
}
```
+ Remove `app.UseBrowserLink();`
Project DNU CMDs
================
* Open PowerShell within **app root**
* Run `dnu restore`
* Run `dnu build`
* Closing and reopening VS at this point helps sometimes.
Myself found it quite difficult to upgrade an existing project, couldn't find all steps required all together.
Hope it helps! | To complete, if you want to update from beta 4 to beta 6, see the Stephen Lautier's answer and to this after :
**To update from beta 5 to beta 6 :**
I did :
* Open global.json and update sdk to "1.0.0-beta6" and save this file
* Visual Studio 2015 proposes to download beta6, click on Yes
In project.json :
* change dnx451 (or dnx452) to dnx46 (To use Framework 4.6)
* replace all "-beta5" with "-beta6" in this file
* remove Microsoft.Framework.ConfigurationModel.UserSecrets
In Startup.cs, if you use Session :
* replace app.UseInMemorySession(...) with app.UseSession()
* In ConfigureServices, add this :
```
services.AddCaching();
services.AddSession();
services.ConfigureSession(o => { o.IdleTimeout = TimeSpan.FromSeconds(10); });
```
* Right click on your Project > Properties > Debug > Add a new Environment Variable :

See that for more information : <http://jameschambers.com/2015/07/launching-an-asp-net-5-application-from-visual-studio-2015/>
* In Package Manager Console, write this "dnu restore" and this "dnu build"
* Restart Visual Studio
My project work in beta6 after that, maybe there are other things to do. |

Hope it helps! | This is the thing:
You updated the DNX from beta4 to beta5, and you want to run an MVC6 template inside Visual Studio RC (whose templates were built around beta4).
In the first place, `"Microsoft.Framework.Configuration.Json"` doesn't exist in beta5 anymore. (you should definitely see this: <https://github.com/aspnet/announcements/issues?q=milestone%3A1.0.0-beta5> - breaking changes from beta4 to beta5).
In order to see that your DNX was updated properly, build a new empty web project and simply add MVC/WebAPI (simple cases to check that it works).
I haven't tried to run the MVC template yet, but I will try and come back to you. |

] | After speaking with @davidfowl from the ASP.NET vNext team, he told me that Browser Link doesn't work in beta5 and should be removed. | This is the thing:
You updated the DNX from beta4 to beta5, and you want to run an MVC6 template inside Visual Studio RC (whose templates were built around beta4).
In the first place, `"Microsoft.Framework.Configuration.Json"` doesn't exist in beta5 anymore. (you should definitely see this: <https://github.com/aspnet/announcements/issues?q=milestone%3A1.0.0-beta5> - breaking changes from beta4 to beta5).
In order to see that your DNX was updated properly, build a new empty web project and simply add MVC/WebAPI (simple cases to check that it works).
I haven't tried to run the MVC template yet, but I will try and come back to you. |

] | We use the same idea as Ross Millikan. In order to bring out the structure, there will be as little calculation as possible.
Let the random variable $X$ denote the smallest roll, and let $Y$ denote the sum of the three larger rolls. Then
$$E(X)+E(Y)=E(X+Y)=14.$$
We calculate $E(X)$. From this, $E(Y)$ is easily found.
Let $q\_1$ be the probability that $X\ge 1$, let $q\_2$ be the probability that $X\ge 2$, and so on.
Then $P(X=1)=q\_1-q\_2$, $P(X=2)=q\_2-q\_3$, and so on until $P(X=6)=q\_6$. Thus
$$E(X)=1\cdot(q\_1-q\_2)+2\cdot(q\_2-q\_3)+3\cdot(q\_3-q\_4)+4\cdot (q\_4-q\_5)+5\cdot (q\_5-q\_6) +6q\_6.$$
This simplifies to
$$q\_1+q\_2+q\_3+q\_4+q\_5+q\_6.$$
But
$$q\_i=\frac{(7-i)^4}{6^4},\qquad\text{and therefore}\qquad
E(X)=\frac{1^4+2^4+3^4+4^4+5^4+6^4}{6^4}.$$
**Comment:** Let $W$ be a random variable that only takes on integer values. For any positive integer $n$, let $q\_n=P(W\ge n)$. Then
$$E(W)=\sum\_{n=1}^\infty q\_n,$$
provided the sum is defined. | One approach is to find the number of rolls with each number as the lowest. There is only one roll with $6$ the minimum. There are $2^4-1=15$ with $5$ the minimum. This continues to the fact that there are $6^4-5^4=1296-625$ rolls with $1$ the minimum.

14,503,449 | I have a large delimited txt file with two columns and about 17 million lines. I have imported it to the database, mistakenly one column in table had shorter size than the text from the file. i.e. varchar (4000) instead of varchar (7000)
about 48 thousands records with longer text has been cut into 40k chars.
How would I replace these without re-importing the files again?
I am thinking if I could be able to filter from txt file only lines with certain length, and remove them, and try to insert update the longer lines.
But How do I select all lines with certain length in a text file? or which program can do that.

] | Depending a bit on how this is connected to other infrastructure, my guess would be that the easiest and safest way of handeling it is just to drop and reimport the table...
If that for some reason not is an option, I would write a script that goes through the text file, and either just updates the large text field unconditionally or checks if it is of a length that makes an update neccesary (ie > 4000 chars)
If there might have been any changes to the table since the data was imported, it is important to check what will be overwritten and that the record really is the one you want to update (depending on how the table is indexed)
Hope this gave you some starting points.
You have my sympathy, been there done it... | You could also build a query that returns every record where that column contains 4000 bytes.
Which are possibly the ones that were cut when you imported the file.
With that set of records in hand, you could try to find them on the file if you have a line reference on the database table ofc. If there is too many, a simple script could do the trick. |
2,312,431 | I need to submit my hundreds of products to hundreds of websites. For most websites I need to select a directory/category for each product. But it seems each website has a different definition of categories. For example, some list laptops under computers/hardware, some under computers/laptop, some under /electronics/computers, some under eletctronics/PCs.

] | Yes, it's hard. No one agrees on the categories.
The Unix "rm" command ("remove") is spelled "del" in Windows. Why? People don't agree on something that simple and obvious.
What kind of magic do you want? Your task requires a *person* to *think*.
A person must (1) understand your products and (2) understand the web site categories and then (3) choose the right category based on the understanding. Think and make a judgement.
Since the web site categories are just words, your software may have to guess and assume at some of the meanings. What does "household" or "consumer" mean? Only in context can you guess at the meaning. | I would try to build a graph with synonyms and generalizations. For example `Notebook` and `Laptop` are synonym. `Computer` generalizes them. `PC` is a synonym for `Computer`. `Electronics` generalizes `Computer` (and its synonym `PC`) again.
Now, for a given product, look at the deepest level of the available categories and look for the most specific synonyms for that product from your graph. If there is no match, move one level up because they may have more specific categories then you graph - they may for example divide notebooks by brands. When you reach the root of the categories without a match move on to the first generalization from your graph and again search from the deepest category level upwards.
This solution has still issues because for example categories may be divided by brand on a very high level or on a very deep level and you choose one option when building the graph. It is quite possible to handle such cases, too, but it will become much trickier. |

This is really not a desirable approach though, as the timer is not guaranteed to always invoke as far as I know, since, like Peter says, your web application is not guaranteed to be alive at all times.

781,300 | We have a website where we need a scheduler to receive notifications (e-mail) on specific time. eg. a person setting reminder at 5 PM to attend the meeting at 4:45 PM, will receive email at 4:45 PM about same.
As this site is hosted on shared server, we don't have any control over the server to run any SQL Job or scheduler application.

] | With ASP.NET you are not guaranteed that your app is alive at all times, and thus web applications as a host process for a scheduling solution is not feasible IMO.
A Windows service is what you need for this scenario. You have full control on starting and stopping the process as well as ways of monitoring the application.
Are you able to host such a service on a different machine? Even if the web application is running on a hosted server doesn't mean you have to run the scheduler on the same server. | However if you really are completely stuck and have no choice but to host it in your WebApp,
You could look at creating a `System.Timers.Timer` instance in your Global.asax.cs file. Wire up a Elapsed event as you normally would, and give it some code that does something along the lines of
```
protected void myTimer_Elapsed(object sender, EventArgs e)
{
if(System.DateTime.Now Falls in Some Configured Time-Window)
//Do Stuff
}

* The native variable that you can use `android`
* The one that you import from `import { android } from "@nativescript/core/application";`

AndroidActivityEventData,

Android.addEventListener(AndroidApplication.activityCreatedEvent, (event: AndroidActivityEventData) => {

] | You should study the syntax of your expected matches to extract them correctly.
To get the port number value, I'd use
```
regex reg("--riotclient-app-port=(\\d+)");
```
This way, you do not even need to care about the number of digits you match since it will capture a number after a known string.
If the auth token can only contain letters, digits, `_` or `-` you may use
```
regex reg1("remoting-auth-token=([\\w-]+)")
```
where `\w` matches a letter/digit/`_` and `-` matches a hyphen, `+` will match one or more occurrences.
See the [C++ demo](https://ideone.com/oFZq84). | First, you need to escape your str value. Every double-quotes (") character must be escaped with (\")
```
string str = "C:/Riot Games/League of Legends/LeagueClientUx.exe\" \"--riotclient-auth-token=yvjM3_sRqdaFoETdKSt1bQ\" \"--riotclient-app-port=53201\" \"--no-rads\" \"--disable-self-update\" \"--region=EUW\" \"--locale=en_GB\" \"--remoting-auth-token=13bHJUl7M_u_CtoR7v8XeA\" \"--respawn-command=LeagueClient.exe\" \"--respawn-display-name=League of Legends\" \"--app-port=53230\" \"--install-directory=C:\Riot Games\League of Legends\" \"--app-name=LeagueClient\" \"--ux-name=LeagueClientUx\" \"--ux-helper-name=LeagueClientUxHelper\" \"--log-dir=LeagueClient Logs\" \"--crash-reporting=crashpad\" \"--crash-environment=EUW1\" \"--crash-pipe=\\.\pipe\crashpad_12076_CFZRMYHTBJGPBIUH\" \"--app-log-file-path=C:/Riot Games/League of Legends/Logs/LeagueClient Logs/2020-07-13T13-33-41_12076_LeagueClient.log\" \"--app-pid=12076\" \"--output-base-dir=C:\Riot Games\League of Legends\" \"--no-proxy-server";

51,650 | I'm not an expert on theology but I've heard that Christianity is filled with inconsistencies and incongruencies. My question, if this is the case, is whether this is normal for the major theologies or it is a specific fault of Christianity. | 2018/05/01 | [
"https://philosophy.stackexchange.com/questions/51650",
"https://philosophy.stackexchange.com",
"https://philosophy.stackexchange.com/users/30032/"
] | On religious views inconsistency is not necessarily a fault, after all God is supposed to surpass human reason and logic. And many paradoxical notions come from general [monotheistic doctrines](https://plato.stanford.edu/entries/monotheism/), like creation from nothing, omnipotence, omnibenevolence and omniscience, that Christianity and Islam share. Buddhism is different, although some versions of it can be interpreted as mystical monotheism along [panentheist lines](https://en.wikipedia.org/wiki/Panentheism#Buddhism).
We should note that there is no such thing as a monolith Christian theology, there are Catholic, Orthodox, and Protestant denominations, not to mention lesser ones, with multiple theological systems and philosophical interpretations each. On philosophical issues for Christianity specifically see [Philosophy and Christian Theology](https://plato.stanford.edu/entries/christiantheology-philosophy). The official philosophy/theology of the Catholic Church, [Thomism](https://en.wikipedia.org/wiki/Thomism), is considered quite rational and coherent as these things go, even rationalistic. There is the opposite extreme too, called [fideism](https://plato.stanford.edu/entries/fideism/), best known from Tertullian's anti-rationalist motto concerning articles of faith:"*It is to be believed, because it is absurd… it is certain, because it is impossible*". Islam also has rationalistic ([Kalam](https://en.wikipedia.org/wiki/Kalam)), mystical (Sufism) and fanatical (Wahhabism) versions. A version of rationalistic Islamic theology, Averroism, was one of chief influences on Thomism. | Christs teachings were not written down until some time after his death. Given the nature of that, his authority couldn't weigh in on the composition and editing of these. It took some 300 years to settle on the New Testament canon, and the final set is very open to dispute, especially inclusion of The Book of Revelation. There are big divergences between Eastern Orthodox interpretations based on original Greek writings, and Catholic iterpretations based on sometimes bad translations into Latin <https://en.m.wikipedia.org/wiki/Theological_differences_between_the_Catholic_Church_and_the_Eastern_Orthodox_Church>
Very little Christian practice or theology is based on the words and teachings of Christ, but instead the disciples and later community (eg. hell, non biblical,from Norse word). The idea of 'progressive revelation' is essential for this, but poses it's own problems. Reform has happened by various council's, and after the division of the churches by different means within each, such as papal bulls. There is no definitive version of the new testament. It is not considered revealed directly from god, although the apostles experienced pentacost. Some Christian patriarchs have been considered to have final authority of interpretations.
This should most directly be contrasted with Judaism, where interpretation is 'argued out' in rabbinic study, and the body of believers to some extent have sovereignty, even occassionally arguing with the deity. The core religious text is a single definitive one, considered to be the revealed word of god, though there are layers of interpretation open to different degrees of questioning.
Mohammed was able to write his teachings down himself, revealed directly from god, so they are seen in Islam as unchallangeable (with the exception arguably of the gharaniq verses). They have final authority. But schools of jurisprudence have developed profoundly different interpretations.
The core text of Buddhism the Tripitaka was composed by the early community based on sermons of the Buddha, and transmitted orally at first, like the Christian template - the worlds first type-printed book was a Buddhist text, but still over 1,000 years after Buddha. In the Therevada school, around 1/3 of Buddhists, focused on Sri Lanka, this is considered the definitive text, the Pali Canon. In the Mahayana school, focused in China & Tibet, it is authoratative, but other sutras are also revered, often more; and there isn't a clear definitive canon in any of the sub-schools. The Tripitaka is not directly revealed words, but guidance and discussion by a highly developed being (not technically a deity, though he preached to deities including the creator, Brahma). The key divisions are among schools of philosophy within Buddhism. There are substantial disputes between schools over which others have any validity or deserve any respect. There are high degrees of synchretism across the Buddhist world, especially given wedding and funeral rights are not found in the sutras.
Texts, what authority they are considered to have, and the process of authoratative interpretation of them, are crucial to understanding different religions. In Christianity, the discovery of the Dead Sea Scrolls, the earliest written versions of many books of the old testament, and mainly contemporary to Jesus, pose various problems for modern Christianity. I really like the book by Barbara Thiering on this, Jesus The Man <https://www.goodreads.com/book/show/296402.Jesus_the_Man> There are big problems reconciling biblical records of events with Roman records, and this book does a lot to reconcile this, and to explain the doctrinal position against previous religious practices that have been recorded as miracles. Resolving these comes at significant cost to modern religious practices.
The consistency of the bible has implications for all the Abrahamic faiths. It's a big topic <https://en.m.wikipedia.org/wiki/Internal_consistency_of_the_Bible>
Many of the theological disputes or contradictions (eg. Problem of Evil, & theodicies against it) arise out of textual issues. |

] | You can use a `PropertyModel` for the textFields. Pass the `IModel<Thing>` into the constructor of the `PropertyModel` with `foo` as the property name:
```
add(new TextField("fooFieldId", new PropertyModel(thingModel, "foo")));
```
The `PropertyModel` will figure out that the thingModel is a `Model` and call `getObject().getFoo()` etc.
This assumes the `IModel<Thing>` instance doesn't change, only its underlying object which can be changed calling `setDefaultModelObject`. | Maybe I'm just missing the point, but I can't find a `Panel.setModel()` in the JavaDocs of neither [1.4](http://wicket.apache.org/apidocs/1.4/org/apache/wicket/markup/html/panel/Panel.html) nor [1.5](http://wicket.apache.org/apidocs/1.5/org/apache/wicket/markup/html/panel/Panel.html). If it's something you implemented maybe you could change it not to replace the model object but to call `model.setObject()` instead?

244,170 | I have the following MySQL query that is querying naughty ip addresses from the last 24 hours and ban count >= 2.

] | It's hard to guess without seeing your input format, however I think you are looking for attribute value templates (Using `{ }` in literal result element attribute values). If you change
```
<font family="/body/msg[font/text()]" color="/body/msg/color">
```
to
```
<font family="{/body/msg[font/text()]}" color="{/body/msg/color}">
```
Then the `family` and `color` attributes will get values by evaluating those XPaths, although the Xpath for family looks very suspect. The above would give the string value of the whole msg element, I suspect it should be more like `/body/msg/font` To extract the string value of the font element.

When possible, it's a good idea to avoid repeating large parts of your code (this is known as the [DRY principle](http://en.wikipedia.org/wiki/Don%27t_repeat_yourself), and with the following, if you need to make a change to that `<font>` portion and the stuff inside it, you don't have to change it in three places.

664,693 | I used an app in Windows 7, I think called dimmer to make the screen change its contrast settings so I could dim it lower than the controls of the PC defaults such as function key or the power options in control panel.
Are there any of these type apps for Ubuntu 15.04 or approved for the latest Ubuntu LTS version on a PC-laptop.
My computer has the use of function keys that change its brightness. It uses a 0-8 step brightness scale where 0 is the least bright and 8 is the brightest. 0 is too bright for my comfort level especially at night
Following the suggestion in an answer below I added the following to etc/default/grub:
```
GRUB_CMDLINE_LINUX="resume=UUID=8bcb4169-f5ab-4ab6-b644-23e528088d41 acpi_backlight=vendor"
```
and updated grub
My screen brightness did not go any dimmer than it had before. Oddly the brightness level seems to go to level 2 brightness on a 0-8 scale every time I reboot which it did not do prior to the etc/default/grub change. I reverted my grub file back to previous settings.
I've installed **Indicator-Brightness** but this app does not dim my desktop any further than my function keys do and there are no menus to configure it to do so.
I actively pursued other related questions to find a solution and reporting results of that action here. Its a process that takes time. To those that have provided input, Thank you for being patient.
There are many aspects to graphics, screen brightness, contrasts, color temp, gamma.
I tried
```
xbacklight -set 50
xbacklight -dec 10 and 03 etc.
```
This never increased or decreased beyond the usual 0-8 steps the PC provides i.e. no difference than current function key levels.
Interestingly a comment below my question by Serg Kolo (thanks :) led me to info on `xrandr` via the linked sources at the bottom of the information he provided concerning his script:
```
xrandr -q | grep " connected"
xrandr --output LVDS1 --brightness 0.5
```
I had no idea this was available and already installed - apparently. With the second command in terminal my screen went darker than it ever has. I then tested:
```
xrandr --output LVDS1 --brightness 0.9
```
Which got me back to the usual lowest level. This appears to be changing contrast levels not brightness, which is exactly what I was asking about. A simple command in terminal is as good as an App.
I have since studied [xrandr](http://www.x.org/wiki/Projects/XRandR/) so that I can get an idea of how that command works.
Perhaps someone could explain xrandr in easy terms but until then please explore the information from the link above.
Edit Sept 16
------------
In good faith and collaboration I decided to try the script from Serg's answer below. Following his directions I was able to make this script work for me. I wish I knew how the script determines what the name of my screen is for the use of `xrandr` command but the good news is it works.

] | Follow these steps exactly:
1. Open terminal via `Ctrl`-`Alt`-`T`
2. Create a folder for the script
```
mkdir -p ~/bin
```
3. Open the file `~/bin/setup.sh` in `gedit`.
```
gedit ~/bin/setup.sh
```
4. **Copy** over the code below **save** the file, **close** the editor.
```

gsettings set $SCHEMA $KEY "$OUTPUT" ;
echo "Launcher for Dimmer created"
}
createScriptFile() {
touch "$SCRIPTFILE"

printf "[Desktop Entry]\nName=Dimmer\nExec=%s\nType=Application\nTerminal=false" "$SCRIPTFILE" > "$DESKFILE"
}
createBinFolder
createScriptFile
createDeskFile
createLauncher
```
5. Make the file executable and start the setup script
```
chmod 755 ~/bin/setup.sh && ~/bin/setup.sh
```
That script will create `bin` folder and blank `Dimmer.sh` file.
6. Edit the file `Dimmer.sh`
```
gedit ~/bin/Dimmer.sh
```
7. **Copy** the code below, **save** and **close** the editor
```
#!/bin/sh

if [ "$NEWVAL" != "" ]; then
xrandr --output "$( xrandr | awk '$2=="connected" {print $1}')" --brightness 0.$brightness

] | In a browser environment, you can assign variables by setting a property of the `window` object:
```js
for (let i = 0; i < 8; i++) {
window["a"+i] = "something "+i;
}
console.log(a2, a3);
```
As for your code, use this:
```
window["a"+i] = $('[name="answer['+i+']"]:checked').val();
```
In the `for` loop | ```
for (var i = 0; i < 8; ++i) {
a[i] = "whatever";
}
```
