working notes on linux, tiny models, models that improve themselves, and distributed systems. they change when i find out i was wrong.
linux
the boot path, packaging, and finding out why a box is slow.
- pkgbuild from zero How an Arch package is described, built, checked and rebuilt in a clean chroot, with a worked example for a Rust CLI.
- reading a slow system A triage order for a Linux box that feels slow, from the first sixty seconds down to perf and bpftrace.
- the boot path, from power button to login What runs between power-on and a login prompt on a UEFI Linux machine, and the command that shows each stage.
tiny llms
small models on small machines: memory, quantization, grounding.
- gui grounding How small models turn an instruction and a screenshot into a point on screen, and how they are measured.
- memory math for small models How to estimate weights, KV cache, and working memory before you download a model.
- small models on a mac with mlx Install mlx-lm, run a model, quantize one, and fine-tune it with LoRA on Apple silicon.
self-improving models
models that learn from their own attempts, and the ways that goes wrong.
- how self-improvement goes wrong Failure modes of models trained on their own outputs, the symptom each one leaves, and the guard for it.
- learning from computer-use traces Notes on improving a small computer-use model from its own action logs, kept on the user's machine.
- the self-improvement loop How a model trains on its own checked outputs, and why the checker sets the ceiling.
systems
gossip, content addressing, and consensus across subnets.
- content addressing and cids What a CID is made of, why CIDv1 exists, and what content addressing does and doesn't give you.
- gossipsub on one page How libp2p's gossipsub keeps pubsub traffic bounded with a sparse mesh, lazy gossip, and peer scoring.
- hierarchical consensus, the ipc way How Interplanetary Consensus spawns child subnets, moves state up with checkpoints and down with parent finality, and what that costs.
