Recently I learned HTML+CSS and a bit of jQuery and am building various web-things to stretch my skills and learn more about how to do things the right way. I was a bit surprised at just how many different ways there are to do the same thing using just CSS and JavaScript.
Currently I am build...
Find the length of the longest substring without repeating characters
Any comments on my code? Is there a better solution in terms of runtime?
public class LongestSubstring {
/**
* First version. O(n^2) runtime
* For each character, find the longest substring starting

Naming :
While it's so easy to give short naming to variable, it's just bad practice.
String s
char c
int n
These are examples of what it shouldn't be. It should be replaced so you know just by reading it what the var is coming from.
Example :
String s could be String inputString.
Clear ja...
Yesterday and today I've made a very basic syntax highlight.
It creates a function in the window object that handles part of the job:
(function(window){
var f=window.highlight = function(lang, element){
var lang_defs = f[lang];
if(!lang_defs)
{
throw n...
While writing this review, I edited the code until it became something quite different from the original. In addition to the issues I mentioned, I ended up adding features:
More operators / commands, including trigonometry in degree and radian modes.
Support for multiple commands on a line, s...
I got this code as a legacy code.
I don't really think this is easy to read/maintain code.
can you suggest a way to make this more readable code, and yet still save the performance here.

I was wondering... In the standard library of some Prolog systems, there are meta-predicates like maplist and foldl.
In general, when using meta-predicates (like the ones above) with dcg we always need the "foldl" variants. What about the following mapfoldl/5 (mapfoldl//3)?
mapfoldl(P_4,Xs,Zs,S...I'm trying to create a list from a string with items alternating between words and parse characters like ['Hello', ' ', 'World']
Is there a built in function, exiting module, or simpler way to achieve something like below?

I'm currently using NDepend while developping a C# application. I get a violation on a rule stating that "Types with disposable instance fields must be disposable".
I know you should in fact do that when you do something like this:

I am quite new to Python and I have trouble finding the roots of a function.
First a bit on what I want to do:
The ultimate goal is to find $$y=(a_1,p_0,\theta)$$ such that they minimize the function \$-\sum\limits_{j=1}^{n} ln(p1_j(a_1,p_0,\theta))\$.
For each possibility of \$a_1, p_...

I was having fun implementing some really basic stuff for 3D graphics. See what I came up with:
Matrix.java:

* @version 1.6
*/
public class Matrix {

While playing with the Concurrency features in C++11 I noticed that there wasn't any support for continuations. I wanted to develop something similar to Tasks in The Parallel Patterns Library (PPL), where a Task can run asynchronously and execute a continuation upon completion using the 'then' m...

Is this idiomatic?
Is there a preferable data structure?
