Research Topics

An assortment of R&D topics on which I spent some time lately.

• Digital Audio Mixing (signal processing): Notes on combining two or more digital audio samples with minimal loss of quality.
• The Gamma function and an arbitrary precision implementation (numerical mathematics): Computing the Gamma-function on a handheld calculator was one of my first programming projects.
• IP Tunnelling (computer networks): A case study of a specific solution employing IP tunnelling, network address translation, and other features to link a company's offices over the Internet.
• Noise (signal processing): A simplistic explanation as to why adding noise to a digitally sampled signal can actually improve its quality.
• Physics notes
• The Pioneer Anomaly
• The Seas of Mars (planetary science): An interactive Java applet that shows you what Mars (or Venus, or the Moon) would look like, were it covered with water.
• Viktor's Amazing 4-bit Processor (hardware design): Hey, I am a programmer with a screwdriver!
• The W Programming Language (programming languages): W is a lightweight, C-like (but keywordless and typeless) language that I invented for use as a "native" development system on DOS-based handheld computers.

• Technical notes are a collection of notes and opinions on computing topics.
