I started a new software defined automation project. I wanted something that I could just open a webpage and start writing code that could just be uploaded and ran instantly. I picked an ESP32-P4 for the first hardware. It’s MIT licensed and has a git repo that I put up this morning https://github.com/OpenPiLab/pilab-esp32-p4-plc

A high-throughput multicast Bitcoin transaction distribution system, with a roadmap towards billions of transactions per second.

Features:

- Control channel for block header announcements, operational mechanisms, and network topology automation

- Separate channels for subtree, subtree grouping, and transaction load

- Transaction load sharding by deterministic multicast group membership based on TXID

- Transaction specialization filtering and retransmission both unicast and multicast, to connect edge networks only interested in a portion of the transaction load for whatever reason

- NACK-based retransmission of missed packets via hash chain gap sequence tracking (per sender, per shard) with automated caching endpoint beacon discovery and tiered network distribution

- BGP-AnyCast based transaction ingress

Basically all the topology pieces to scale the actual small-world network for Bitcoin miners or transaction processors; dense at the core, with layered and sharded group distribution towards users at the edges. Right now just site or org-scope multicast in planned, but provisions are being made to extend via MP-BGP eventually.

For BSV Blockchain but could work for the other Bitcoin variants too, if they ever wanted to scale.

Currently working on `imgsrv` which is basically a container registry but it holds disk images. Enforces versioning, allows attaching multiple formats for a single release, prioritizes immutability, etc. Intended to build fully automated image release pipelines. I use a PXE setup for my homelab, so having a common place to manage image release lifecycle is helpful.

Right now I intend to make it compatible with Incus as a remote. So it's just a matter of adding it as remote and then you can consume all of your versioned images.

I finally managed to finish a project and publish my first game on Steam: https://store.steampowered.com/app/4195030/balls/

It's a short chain-reaction game in which you explode balls bouncing in the screen, and need to build up to target scores. You build bigger and bigger combos as the game progresses.

It was a blast to work on it, starting with a small toy and just adding features that "felt right" until I had a game that was fun to play. It was quite hard to find a balance though, so a lot of numbers are arbitrary - but I enjoy seeing people breaking the game in new ways and finding new builds.

These days I've been working on patching reported bugs and sharing the game with people. Now after the latest patch, I feel like I'm done, but I feel like going back at it and adding an idle mode. And maybe simplify the codebase so I can test and iterate better, and then add many more ball types...

I know that any good LLM could replicate this pretty quickly, but I made this myself and I'm still feeling proud of the accomplishment :)
