In 2021 I co-authored the book Real Programming (Ekte Programmering in Norwegian) with Sjur Julin. It's a book about programming, programmers, programs, and pop culture. Some of it is based on articles published here, and all the source code can be downloaded for free. The Norwegian version is available from The National Library of Norway. The info page has some sample chapters and a 10-page summary, so you can find out whether it's entertaining or not. It's quite different from all the other books about programming out there. Not everybody likes our writing style, and that's quite ok. Have a look at the code instead.
I write ultra-high-performance code in C and intrinsics, C++ when needed, Assembler when necessary, and GLSL if there's a GPU available. Some of the architectures I've used are Motorola 68000, PowerPC, ARM and Neon, TriMedia/PNX (fun), Texas Instruments DSPs (crap), Tilera TILE-Gx (great), Intel SSE/AVX variants, Intel Movidius Myriad X, and NVidia Jetson Nano/TX1/TX2/Xavier/Orin. I've owned and programmed numerous home computers over the years, the most notable ones being Sinclair ZX81, Commodore 64, and assorted Commodore Amiga models. I tried booting my old Amiga 4000 from 1992 in 2019: It's covered in the book.
My main area is code optimization and parallelization, but I've made video pipelines, threading frameworks, menu systems, camera controllers, communication systems, fast encryption and hashing routines, laser galvanometer controllers, and fixed a lot of obscure bugs. And that's just professionally: I do a lot of hacking in my spare time, too. Many examples can be found in the Source Code section.
Sjur and I gave a guest lecture about the necessity of low-level programming at the University of Oslo in November 2022. If we ever do another one, I'll try to take some better pictures. Feel free to contact me if you want an hourlong rant about the failure of modern development methods and how hard problems with complex solutions usually can be solved in much simpler ways. A word of warning - my lectures have been described as both dry and terse.
I currently work for Huddly as a principal engineer. They make cool USB and network cameras. Think LifeCam, only the complete opposite. It's part-time, so I occasionally do other stuff. If you have any kind of interesting programming problems not related to web crap, please do not hesitate to contact my company: Ignorantus AS.
I worked for Stingray Marine Solutions AS 2018-2020. Killing sea lice with a laser is awesome! (Well, lasers are always awesome.) In the period 1999-2018, I worked for TANDBERG, the videoconferencing company, which was acquired by Cisco in 2010. TANDBERG was pretty great. Cisco wasn't. Before that, I was at PCTVNet, maker of an early internet set-top box called the HomePilot. In the middle of the 90s, I spent a couple of years at Statens Pensjonskasse, converting old systems to "modern" C and embedded SQL. They used cool DEC Alpha servers, so it wasn't as boring as it might sound.
Rewinding to the start of the 90s, I studied mathematics and informatics at the University of Oslo. We learned object-oriented programming in Simula; that's probably why I don't like OOP anymore. Back then, they had a course where they taught Assembler and C programming on Atari ST. That was quite fun. I recently recovered the diploma (with my name written incorrectly, hmf) from storage. Going back into storage, I guess.
I've made several videos over the years that demonstrate what I do. More are available in the Videos section.
The Xmas Demo 2022 for the NVidia Jetson AGX Orin developer kit with 2048 GPU cores. In cooperation with Sjur Julin. A more refined version of last year's demo. It's bigger, better, and faster. Contains 20 percent new material and music by Kevin MacLeod.
The Xmas Demo 2017 for the NVidia Jetson TX2 with just 256 GPU cores. In cooperation with Tor Ringstad. The original where we implemented a series of insane (and sometimes inane) optimizations to make fancy ShaderToy effects run in 60 fps.
I recommend using LinkedIn for that. Due to a series of unfortunate events, the disposable email system had to be scrapped (again).
