About

Hi! I’m Karl Schultheisz. I’m a programmer. Check out my source code repositories).

I’m interested in

• audio signal processing
• compilers and programming languages
• embedded systems
• fuzz testing
• intellectual property
• Linux kernel
• reverse engineering
• system programming
• troubleshooting

Some things I’ve done:

• harec (Hare bootstrap compiler) (2022)—robustness improvements
• ode2dsp (2021)—a code generation tool for DSP engineers (prototype)
• simpleiot (2020)—GUI development in Elm, backend in Go, using bolt as a datastore
• kappa (2019–2020)—a concatenative programming language based on “lambda compose” (proof of concept)
• vis text editor—small contributions
• auklet (2016–2018)—a CPU profiler and crash monitor for multithreaded embedded Linux apps

If you like my work, consider donating.

I have some sysadmin experience, running

• a small Nextcloud instance for family use
• OpenWRT on my home router(s)
• a Raspberry Pi for pi-hole
• various machines running Arch Linux, Alpine, Ubuntu, and postmarketOS

I also tinker with oscilloscopes and soldering irons sometimes, and with my home music studio. I get excited about open source audio gear like Mod Devices!
