Generate random hex-string and calculate base58encode. I made these for some initial BTC-testing, but didn't test too much... seems to work, but would need some unit-tests... :-)
module BtcTesting

let base58encode (hash:byte[]) =
let code_string = ['1'..'9']@['A'..'H']@['J'..'N']@['P'..'Z']@['a'..'k']@['m'..'z'] |> List.toArray
let data = hash |> Array.toList

Analyse word count from files. You can use it e.g. to create Tag Clouds
//From NuGet: Sparc.TagCloud
#if INTERACTIVE

#else
module MyTagCloud

Musical Note Frequencies: With the usual Western music it is common to use the Equal temperament: http://en.wikipedia.org/wiki/Equal_temperament http://hyperphysics.phy-astr.gsu.edu/hbase/music/et.html Then the note frequencies are calculated by this formula. For more information: http://en.wikipedia.org/wiki/Pitch_(music) http://en.wikipedia.or…
/// (Infinite) list of note-frequency -pairs
let tones =
let bass = 55.0
let octave = ["A"; "A#"; "B"; "C"; "C#"; "D"; "D#"; "E"; "F"; "F#"; "G"; "G#"]
let notes = seq { while true do yield! octave }
let frequency = bass |> Seq.unfold (fun x -> Some (x, x*System.Math.Pow(2.0, 1.0 / 12.0)))
Seq.zip notes frequency
//let ``guitar open A`` = tones |> Seq.nth 24 // val it : float * string = (220.0, "A")
