Scheme interpreter in F#
A small Scheme interpreter using Higher Order Abstract Syntax (HOAS) encoding for terms. The essence of the technique is to use F# (meta-level) functions to encode Scheme (object-level) functions and other binding constructs, thus avoiding the need for representing variables, bindings, explicit substitution and dealing with shadowing.

Finding matching pairs in two sequences
Here's a function which takes a comparator function and two sequences, and returns tuples consisting of an item from each sequence, where the comparator function returns true for those two items. This is a small part of my wider project to generate guitar chord shapes. One of the requirements there is to take a list of 'wanted' notes for a chord, and a list of 'available' notes within a range of frets and to combine them into an actual set of frettings. That's what led to tryFindFirstPair and hence to findPairs.

What word is most like the word "turtle"?
A while ago I posted a snippet to calculate the 'Discrete Fréchet Distance' between two curves. If we treat a word as a 'curve' by giving each letter an index (with similar-sounding letters having closer indices) we can compare words by the Fréchet distance between them! An alternative to edit-distance...

Monad Bind 2 of 3
After watching this clip (http://www.youtube.com/watch?v=ZhuHCtR3xq8) on Youtube featuring Brian Beckman I wanted to try to sketch Brian's main argument that Monads' main purpose is function composition. I will post my sketch to http://rodhern.wordpress.com/2014/02/ . These snippets are the companion examples to the blog post.

Pascal's Triangle (2)
This code sample generates Pascal's triangle as jagged 2D list (list of lists). It takes 0.5 sec to generate 3000 rows (vs 16 sec for http://fssnip.net/23). Tip: try to avoid of using "list1 @ list2" construction.
