Now

What I'm focused on right now. Last updated September 2026.

Inspired by Derek Sivers's /now movement. A short snapshot of what currently has my attention.

Publishing

  • Treating the completed Kafka Engineering course and Redpanda study as stable entry points into the systems archive.
  • Continuing source-guided writing on production systems, open-source internals, and model infrastructure.

Improving

  • Applying the Practical Systems Essay voice: concrete mental models, production constraints, sourced claims, and explicit failure modes.
  • Making strong existing work easier to discover without changing the chronological archive or narrowing the subjects I write about.

Keeping deliberately small

  • No on-site comments. Feedback stays on email and social channels.
  • No automatic publication without a human pass, even when a target date has arrived.
