CSS Star Rating System
in CSS added by admin, 5 days ago examples intermediate style
Recently I had to create a Star Rating system for a client so I thought I'd share with you the techniques I used to accomplish this. If you are not familiar with a Star Rating System, it's simply a method of voting using (usually) 5 stars in a row, which will change colour as you hover over them indicating the level at which to rate something.

A Lightweight Approach to Aspect-Oriented Programming in Python
in Python added by admin, 3 weeks ago aspect-oriented intermediate
aspects.py library provides means to intercept function calls. Functions and methods (also in Python standard library and third party code) can be wrapped so that when they are called, the wrap is invoked first. Depending on the wrap, the execution of the original function can be omitted, or the function can be called arbitrarily many times. Wraps are able to modify the arguments and the return value of the original function. In the terminology of aspect-oriented programming, the library allows applying advices (wraps) to call join points of methods and functions in around fashion.

Learning Python Programming Language Through Video Lectures
in Python added by admin, on 8/3/2008 beginner tutorials video lectures
One of the upcoming projects I am doing (I will reveal it in one of the next blog post) is going to be written entirely in Python. I have a good understanding of Python but, same as I had with JavaScript, I have little experience doing projects from the ground up in it. Before diving into the project I decided to take a look at a few Python video lectures to learn language idioms and features which I might have not heard of.

Adding Type Checking to Ruby
in Ruby added by admin, on 6/2/2008 intermediate type
What’s the first thing you think of when you consider the Ruby Language? Dynamic types, right? Ruby is famous (infamous?) for its extremely flexible type system, and as a so-called “scripting language”, the core of this mechanism is a lack of type checking. This feature allows for some very concise expressions and a great deal of flexibility, but sometimes makes your code quite a bit harder to understand.

Python as Config Language -- Forget XML and INI files
in Python added by admin, on 12/1/2008 configuration-file
A programming language has all the advantages as a language for encoding parameters. I see why it's rare -- too many programmers have spent too much time with MS's abominable INI files and think it's "normal".

Ruby blocks gotchas
in Ruby added by admin, on 31/12/2007 blocks intermediate metaprogramming
There's this thing they say about Ruby - everything is an object. It's true, with very few exceptions, one of them being the block. Well guess what, this little gem of an inconsistency came back to bite me when I was trying to do something involving dynamic redefinition of methods.

Human-Readable Encryption Keys

Somehow, we have to present these random 128-bit keys to the user, and I think I've found a pretty good way. We use RFC 1751, which defines a 'Convention for Human-Readable 128-bit Keys' - basically just a mapping of blocks of bits to strings of English words.

Well, Ruby 1.9.0 landed yesterday, as expected. I’d be remiss if I didn’t start out by thanking matz, ko1, and all the other hackers involved in getting this milestone release out the door. It’s a great step for Ruby, and one that we’ve been waiting a long time for.

Damn Cool Algorithms, Part 3: Anagram Trees
in Python added by admin, on 24/12/2007 algorithm general intermediate search tree
When it comes to finding anagrams of words, a frequent approach is to use an anagram dictionary - simply put, sort the letters in your word to provide a unique key that all anagrams of a word have in common. Another approach is to generate a letter-frequency histogram for each letter in your word. (Both these approaches are more or less equivalent, in fact.) These approaches make the problem of finding exact single-word anagrams for strings very efficient - O(1) if you use a hashtable.
