I have been writing code for decades and it still buzzes the same way it did on day one. Most of what I build lands somewhere between decentralized networks, radio and low-level systems, usually in Dart, C or Python. Here is what I am spending my time on.
Most Wi-Fi deauth tools stop at 2.4 GHz. This one runs on the ESP32-C5 and hits 5 GHz too, and I drive the whole thing over Bluetooth from a phone instead of a serial cable. It turned out to be the repo people actually found, sitting near a hundred stars now.
I wanted I2P inside a Flutter app without shipping a native router or asking anyone to install one. So I wrote an I2P node in pure Dart: it traverses NAT, addresses files by their content and needs no config. Drop it in and the app is on the network.
A Wikipedia for files. Anyone can browse what is there, keep a copy and add their own, and there is no server to seize because every client is also a relay. It rides on Nostr and I2P only, which keeps it hard to shut down and easy to run.
ZPAQ is a wonderful archiver for incremental, deduplicated, versioned backups, but it is C++. I ported it to pure Dart so Flutter apps can read and write those archives directly, and the output stays byte-compatible with zpaq 7.15 and zpaqfranz.
A miner you can actually live in. It runs its own Monero P2Pool node with RandomX and mines Cryptoescudo too, and around the mining it carries wallets, a contact list and per-coin chat rooms, all talking over I2P.
I got tired of the flat Alt+Tab. This replaces it with a globe that spins to your open windows, lit by wherever the sun actually is right now. Plain X11, no desktop extension to fight with.
The same daylight idea, sitting still. It paints the live day and night terminator across a world map and sets it as your GNOME wallpaper, refreshing every ten minutes and working offline after the first run.
Be nice to each other, have kids and use GraalVM.
