Jakob's Personal Webpage
Hey! I'm Jakob. Welcome to my website. I'm a current undergraduate at the University of Massachusetts Amherst studying computer science. I do a lot with programming, computer security, and lifting weights. I am occasionally active with the capture-the-flag teams 0xBU and To Shell and Back.
An alternative Gopher site mirror is available at this same domain.
- Nekopack - a tool for extracting game data from the XP3 archives used by Nekopara.
- Hypodermic - proof-of-concept shared object injector for Linux.
- r2-acs - a plugin for radare2 to disassemble Doom ACS bytecode.
Free Software Contributions
- radare2 - a UNIX-like reverse engineering framework. I've done a little bit of hacking on Dietline, their GNU readline reimplementation.
- GZDoom - a ZDoom-based source port with an accelerated hardware renderer. I was responsible for the discovery of a critical security vulnerability in the ACS interpreter.
- PINCE - a reverse engineering tool that'll (hopefully) supply the place of Cheat Engine for Linux. I am also the maintainer of the Arch Linux package.
- toxic - an ncurses-based Tox client. I was responsible for that horribly unmaintained Python scripting API.
