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.

14 CAN-L

16 +12V

pin 16 is always live, so deep sleep when the ignition's off or it flattens the battery

PIDs, mode 01:

0Crpm = (256A + B) / 4 0Dspeed = A km/h 10MAF = (256A + B) / 100 g/s 5Efuel rate most cars don't report it

fuel L/h = MAF · 3600 / (14.7 · 740)

AFR

g/L petrol

L/100km = L/h ÷ km/h × 100

not at 0 km/h!!

+4 min late

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

SSE, not websockets. data only goes one way and the browser reconnects by itself

v1: open the latest autosave and parse it

ironman saves are encrypted. dead end

v2: steam already knows what I'm doing

steam ID3 from the install folder
scrape paradox's own rich presence off my steam profile
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

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

13.07.25 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. 12.08.23 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. 16.12.25 rng visualizer a toy for watching random number generators fail. RANDU falls into 15 planes. live demo inside.
