bream

Bream is a subset/dialect of Scheme that is compiled to run on an alternative platform. More details & initial sources will follow soon.

IntSeq

IntSeq - Integer Sequence & Transformation library for Scheme

OEIS-Djinn

Source code for OEIS-Djinn project.

Finnish-Verb-Conjugator

Finnish verb conjugation routines in C and C++, coded in 1993 - 1997, with a slight change in character coding in 2003. Can generate all possible productive conjugations from each Finnish verb root.

lifemidi

Verilog source for my green Lifemidi box, for producing lights and MIDI-music.

A089840-programs

Two programs that illustrate the creation of OEIS array A089840, which lists signature permutations of non-recursive Catalan automorphisms, that is, bijections of finite plane binary trees, with no unlimited recursion down to indefinite distances from the root.

RacketWorkshop

Course Material for my Racket Workshop (in Finnish and English)

St.-Vitus-Lisp

My very compact Lisp-interpreter for MS-DOS, the last build done February 21, 1992 !

Polyhex

A simple Prolog-program to search for polyhexes (polyominoes in hexagonal lattice) and similar structures, related to Fusenes and Helicenes.

PDP-11-assembly-snippets-and-ODE11-emulator-for-MS-DOS

Simple-FPGA-VGA-videomemory-demo-with-PS-2-mouse-input

Verilog code for demonstrating how a Digilent's Spartan-3 FPGA devboard can be programmed to implement a VGA video memory to which can be drawn with a PS/2 mouse.

A080069-etc-programs

Python script for drawing "Wolframesque" images (like in Wolfram's magnus opus New Kind of Science) of various iterated systems based on Catalan bijections applied repeatedly to a Dyck path (or equivalently, a rooted binary tree) whose size is increased at each iteration.

Kanji-dictionary-old-and-new

Source code and data for the Kanji Dictionary program that I first wrote (in 1990) for MS-DOS, and then later (1994) started porting (with Franz Lisp) as a Web-service. Nothing is guaranteed to work anymore, but the data could be useful!
