I'm interested in functional programming, type theory and very applied math - including systematic trading, statistics, artificial intelligence and machine learning.

I'm working on an AI Library in Haskell. Feel free to fork.

comment Ideals and filters
Thanks Qiaochu. I guess my question, then, is why isn't there an associated notion of a filter for general rings? What blocks it?

comment Grasping mathematics
@Matt "Computer science isn't really heavily reliant on math." I disagree. Theoretical computer science (Turing, Church et al) basically is mathematics. Functional programming languages (Lisp, Haskell) are mathematics expressed as computer code. Good algorithm design requires knowledge of computational complexity (Knuth et al) which is mathematics. Good OO program design benefits hugely from an understanding of mathematics (functions, relations, predicates etc). Many programming tasks (search, optimisation, scheduling, graphics) have inherently mathematical solutions. CS relies on math!

comment Step function for greaterthan
My interest is piqued - why can't you use an if statement, and what possible implementation of the step function causes it to be slower than mixedmath's solution, which uses a division and exception handling?

comment “Casual” mathematical facts with practical consequences
In addition, I understand that many conjectures in algebraic topology and knot theory are trivial in dimension 2 or less and dimension five or greater, but are interesting in dimension 3 or 4. For example, in 2 dimensions only the trivial knot exists (by the Jordan Curve Lemma) and in 4 dimensions any knot can be un-knotted to form the trivial knot. Dimension 3 is the only one in which the theory of knots of 1-dimensional ropes is non-trivial.

comment Things I must know before taking differential equations course
I would also recommend Schaum's book for calculus, and Ordinary Differential Equations by Pollard and Tenenbaum for DEs.

comment How to understand and appreciate the prime number industry?
@Fahad Yes, it's the lowest prime whose factors aren't obvious after a few moments thought (by me).

I encode all my data using RSA and a public key of 259.
