matthias paulsson
Senior engineer in hosting.
20+ years on Linux. Arch daily driver on a ThinkPad. Sailfish OS on the phone.
VyOS on the router. Proxmox everywhere.
Currently based in Malta.
Originally from Älvdalen, Sweden, a place small enough that everybody knows everybody
and cold enough that you spend a lot of time indoors learning things.
I have spent the better part of two decades keeping things running that cannot go down.
iGaming infrastructure, production networks, systems where the cost of being wrong
is immediate and measurable. 99.9% uptime is not a marketing number when real money
moves through your stack every second.
I run Kubernetes for clients on VMware.
I run LXC at home on Proxmox.
I have opinions about both and they are not the same opinion.
I started on IRC-era Linux when you compiled everything yourself because that was
the only way to get it working. That habit never left. If I do not understand how
something works I am not comfortable running it.
kernelcraft.net exists because most Linux content online is written by people who
read a man page once. I write about things I have actually built, broken, fixed
and sometimes broken again on purpose to see what happens.
$ cat current_projects.txt
Building oddsynapse.com — an iGaming affiliate intelligence platform
with real-time operator scoring, fraud detection and behavioural analytics.
Go backend. ClickHouse. The whole thing runs on infrastructure I designed from scratch.
$ cat interests.txt
Modem internals and cellular stacks.
Sailfish OS and mobile Linux.
Security hardening at the kernel level.
Network architecture that actually scales.
VyOS. Proxmox. Anything low level.
Herpetology. Fishing. Norse mythology.
Permaculture. Mead.
