I've edited unregistered at least from the following IP addresses:

• 82.181.66.63
• 130.234.180.167

I've contibuted in trying to fix some inconsistencies and unbalanced omissions as well as in incorporating new references, mainly about computer programming.

One starting-point for my contributions is the article on Haskell programming language. Haskell is fairly standard, modern and advanced, which together with pure functional programming give an alternative view on many programming topics. Articles with my biggest contributions this far include:

• Pattern matching
• Operator (programming)
• Operator overloading
• Guard (computing)
• Algebraic data type
• List comprehension

Articles I plan to collaborate on:

• Polymorphism (computer science)
• Type class
• ZigZag (software)

Articles I've started from scratch include:

• Data type
• Virtual console
• Text terminal
