TIL ~35% of the compute on our old Next.js app was RSC prefetch requests

Links prefetching pages on hover and on scroll, mostly pages nobody opened. In one 30 min sample it prefetched homepages across 327 different blogs

Turned it off everywhere w/ a Link wrapper + a lint rule that blocks the default next/link import

(new app is TanStack + Cloudflare. still no regrets)

330 commits to master last week from 5 of us, most of it written w/ coding agents

Side effect: CI (@depotdev) quietly became a bigger bill

Two thirds of our runner time was 16 and 8 vCPU machines sitting at ~1% CPU, waiting on a Docker build running somewhere else

Moved those jobs to 2 vCPUs. ~$550/mo off a ~$930 bill, in one PR

Your team should be announcing something every week. Most don't, because shipped features get buried in merged PRs and nobody has time to write them up.

The new Ideas page reads your GitHub merges, surfaces what's worth announcing, and drafts the content for you
