Joel K. Pettersson's personal site

Welcome. This site has things mostly focused around my interests more broadly, especially technical interests and what's not found in other places. Odds and ends among hobby projects and explorations for the most part.

A main hobby since 2018 and with a separate site is the saugns program and SAU "Scriptable AUdio" language, the further development of stuff I experimented with in the early 2010s. Before that, I've worked on other hobby audio DSP coding since the mid 00s, but most of it is rough in the quality of what it did and the code for it not yet out there (but that may change in the future).


About me

I've been interested in software programming since 2001, when I began to experiment with a first hobby project in my teens. Since then, I've worked on and off on hobby projects, but don't yet have any professional (as in paid work) experience. I've also studied some undergraduate computer science and engineering, which I left behind some years ago, but think of returning to and completing.

Other interests include philosophy and psychology. I've explored a lot over the years, and gone through a lot inwardly; I don't yet have much of a personal philosophical synthesis that I'm satisfied with, but such could develop over time. Maybe I'll write more in that area later.

On potential jobs

In the past, I've only got the rare job offer for the kind of web programming I have no experience with; I don't know (though could learn) the latest web programming frameworks and popular languages, and don't do much in the way of graphical design. The fanciest web-related programming I've done has been in PHP and dealt with MediaWiki functionality (which I find somewhat interesting – but I have no such project to focus on at this time).

Some main things I've explored as hobbies include DSP (programming), and UNIX-like operating systems (as a long-time intermediate-level user). Mostly I've used the languages C and C++ for my hobby programs. It could be interesting to branch out further into scientific programming and/or systems programming.

Where I am

Physically, usually in Sweden. But on the web...

You can reach me through email; at, I'm "joelkp".

Not f'd—you won't find me on Facebook.
