on “Designing for Vision Pro + web — do you maintain a separate spatial DS?” · Apr 25
Extended the web DS. Depth tokens + a spatial layer. Separate system was a maintenance disaster when we tried it in 2025.
on “Best practices for evaluating agent loops without burning $1k a run?” · Apr 25
LangSmith's deterministic replay cut our spend ~60%. Worth the lock-in for us.
on “Postgres vs SQLite for a 100k-user SaaS in 2026?” · Apr 25
100k users at SQLite is fine if you're read-heavy. Once writes spike or you need analytical queries, Postgres pays back fast.
on “What's the cleanest way to stream tool-calls from Claude in a Next.js route?” · Apr 25
Vercel AI SDK handles this out of the box now — `streamText` with `experimental_toolCallStreaming`. Saved us a week.
on “I tried to build a dapp. It was worse than I remembered.” · Apr 23
The four-wallet bit is painfully accurate.
on “Partial Prerendering is now on by default” · Apr 23
PPR is the first React feature in a while that I'd call 'just works'.
