Software without abstractions, built for real-world tooling.
I tackle anything from maps and data intensive applications to reverse engineering and hardware projects. The best way to solve problems is to approach everything with care and an open mind.

0Dspeed = A km/h
10MAF = (256A + B) / 100 g/s

- 1. the recorder logs every vehicle arriving at every stop
- 2. stored in timescaleDB
- 3. matched against the GTFS schedule
- 4. → per-stop delay analytics

v1: open the latest autosave and parse it
ironman saves are encripted encrypted. dead end
v2: steam already knows what I'm doing
- 1. steam ID3 from the install folder
- 2. scrape paradox's ownrich presence off my steam profile
- 3. pypresence → discord
"Leading as Basileus of Byzantium in war against Epirus in 1445"
that's steam's text, not mine
more than one steam account on the PC?
→ ID3 goes in the config by hand
it works! my discord profile

todo: transit map
- buses + trolleys
- metro, tram
- trains (GTFS-RT)
- docker compose on the pi
- recorder → timescaleDB p.45
- per-stop delay page
- write a README
route shapes come from OSM overpass
misc
- – RANDU in a 3D plot = 15 planes. still funny
- – lightshot IDs went random after 2022. the old sequential fuskers are done
- – supabase: check RLS. every table

insecure vibes
a vibe-coded click counter, its supabase keys in the network tab and RLS switched off. flooded it from the devtools console in a few minutes.

lightshot fuskering
prnt.sc links used to be sequential. people's private screenshots were a counter away, plus the same crypto scam every few minutes.

rng visualizer
a toy for watching random number generators fail. RANDU falls into 15 planes. live demo inside.
