+## Transformers
+
+Learning about [[transformers|transformer architecture]] from an engineering standpoint. The model that's clicking: attention is cross-token communication — tokens talking to earlier tokens. MLP is per-token computation — tokens thinking privately. Updated token vectors come out. Stack those two primitives together and you get the whole thing. Didn't get too far into the actual paper today, busy day.
+
+## Praxis
+
+Woke up early and checked on [[praxis]]. It's in a good state — built out the end-to-end system with notifications working. Some queries are taking a while after getting full fundamental support for filings in.
+
+## Background agents
+
+Built out the AI game today and it was cool to see the superpowers plugin work — used Haiku subagents to write a significant chunk of a game that actually worked well. `/loop` is up there as a favorite Claude Code feature. Trying to apply a similar workflow to Codex: a repeatable task (TDD for example) on every cycle. Want to try a new harness like Pi.
+
+Core takeaway: background agents are critical. The goal is firing at 100% all the time — it's a matter of good overnight prompts, letting agents run, and being able to context switch well.
+
+At peak today: 3 worktrees firing at work + 4 concurrent agents on personal stuff — 7 things progressing simultaneously. Wild to see in practice. The interesting question is what kinds of workflows and skills you actually need to succeed at this. Today felt like a good glimpse of that. Want to be firing on all cylinders like this every day.
+
+## [[ai-games|AI game]]
+
+Planning to shift the objective of the Padmi game away from capture-the-king toward persuading people to make you king — more of a popularity contest. Feels like a better mechanic.
+
+## Health
+
+Good eating day, chest and biceps.
