Alvin's Notebook

Now

What I'm currently working on, updated a few times a year. (Last update: November 2026.)

Building
A minimal API gateway in front of my self-hosted services -- bearer tokens, consistent error JSON, tiny token-bucket rate limiting. Blog post about it here.
Measuring
The home energy fingerprint project is in its second year: the classifier now covers nine appliances and flags anomalies before hardware fails.
Reading
Slowly working through the second half of this year's reading list. Impressions land in the periodic books posts.
Running
The usual fleet: NAS, mail, git, CDN edge, dev tools. Uptime has been boring in the best way.

Previous "now" pages are kept in git history, which is half the point of writing this page at all.
