Work

Virtutech

In July 2003 I started working at a company called Virtutech, which makes an application called Simics. If it's nothing personal, you can reach me there at kha@virtutech.com.

Stuff

I've got a blog

Beating Klotski

This is a puzzle with ten wooden rectangular blocks that you shuffle about on a small game board in an attempt to get the largest block to the exit. I never had the patience to solve this puzzle when I was a kid—and I still don't, but writing a program to solve the puzzle for you still counts, right?

git, the information manager from hell

My source code management system of choice is git. It's fast and convenient to use, and its is extremely simple (which makes it easy to understand what it's actually doing).

StGit, a patch management tool for git

StGit, or Stacked Git, is a tool for managing patch series. It is built on top of git, and essentially provides a convenient way to edit the commit history. I am one of the main contributors to StGit; you can find my development branches on repo.or.cz.

Master's Thesis

I spent a few months implementing and testing a new integer division algorithm for GMP, the GNU Multiple Precision Arithmetic Library. You can read about that in my Master's Thesis.

SPL, the Shakespeare Programming Language

An esoteric programming language, made by myself and Jon. Every SPL program looks like a Shakespeare play.
