@[email protected]Interests:
- Some tech origins, mainly beginnings of #Unix, CP/M, #Amiga, and thus #BCPL / #tripos. Fond of #forth too. Looking up to #lisp #haskell #erlang and #elm.
- Network infra #TCP/IP, #mptcp and #TLS progress.
- Traditional Unix editors such as vi (#vim) - after about three decades of growing into it, more and more of #emacs.
- Text interfaces, #mutt, #tig, #mc
- Fan of version control, coming from #rcs through #git
- I might be a luddite - I don't favour all tech or all vendors.

I'm trans pan married woman and usually I'm #engineering the #cloud. And #gaming (mostly #ffxiv and #genshinimpact) ;)
But really, most of the time I live inside my #vim (technically #neovim these days) and coding.

If I don't get a joke or a reference, please excuse me, ASD has some drawbacks. Let me know in a civil way so I can learn. Thank you :)
(I live on Fedi since around 2017, but now this is my only user, any other ghost users remaining somewhere are just ghosts)
Hi there.
I'm a software engineer and father of 2 kids.
I enjoy learning new things and have a keen interest in furthering the state of FOSS, either through development work or politics (in as much as there is a difference between the two). We'll have to see if anything ever comes from this.
I hail from Denmark, the Copenhagen area.
I have been working professionally with Haskell, Rust, Python, and C#.
Theoretical Computer Science sleeper agent. (The formal methods revolution is coming - and when it does, I will be ready).
