Moved some GitHub Actions runners off Blacksmith ($400+/mo of compute) to an M5 Ultra 96GB Mac Studio at ~$110/mo with compute to spare. Thread context: runners managed with Tailnet (Tailscale) + k3s + actions-runner-controller (ARC); Mac Studio bought from Apple via Klarna financing (~$110/mo), not a hosting lease; also runs runners on an old Dell R630; staging/prod jobs stay in the cloud; on Starlink. A replier (joearroyo) also lets his idle M5 Ultra serve inference on Darkbloom (~34.5k jobs, ~$20).
Thread reply: a homelab makes sense for him at $0.1156/kWh with solar panels; attached NLR degree-day projections chart for La Plata County, CO (heating-dominant climate).
Will Larson (Imprint) on 'small-change': with PRs/eng/week up 4x avg (10x on some teams) and p50 review time 33 to 77 min, CI auto-marks a PR small-change if it's under 1,000 LOC, has no p1/p2 ai-code-review findings, the author has 10+ merged PRs in that service, it touches few services, and it skips shared libs (per-repo .small_change file). A review-small-change skill only approves or ignores (never comments, to avoid 'meat proxy review'), and review-pr-cluster reviews batches for themes. About 10% of PRs qualify so far. Incidents are down 42% and critical incidents down 78% half-over-half.

(Czech) schotek uninstalled Docker Desktop and now uses Apple's native Containers (container CLI 1.3.1) for Linux dev on the Mac: memory use went down and disk I/O is far better. Recommends a GUI dashboard app for managing containers/images/volumes/networks (name truncated in the post); screenshot shows it.
Vercel Labs' tsc-ts: TypeScript's compiler (originally TS, rewritten in Go as tsgo) ported back to TypeScript and compiled natively with scriptc; claimed 2-4x faster than tsgo.

Claude Code Review is GA for Claude Team and Enterprise plans: faster reviews catching more important bugs, and admins choose Quick, Standard, or Deep review level per repo.
ts-rust v0.6.0 (Theo's Rust port of TypeScript type checking)
By Theo - t3.gg · @theo · Oct. 14, 2026
ts-rust v0.6.0 (Theo's Rust port of TypeScript type checking): 30% faster, up to 70% faster with --fast (uses more RAM). Mostly closes the gap with `bun check` while keeping 100% compatibility with upstream TypeScript, which Bun lacks. Quotes his earlier video on why he built it (not just faster type checks).
You can roughly 2x GitHub CI speed for free: GitHub Actions now runs steps in parallel (background steps, changelog 2026-06-25). AI tools often miss it because it's new; ask an agent to apply it and benchmark. https://github.blog/changelog/2026-06-25-actions-steps-can-now-be-run-in-parallel/

Credits pstack and Opus 5.5 with cutting production deploy time by ~30% after giving the agent full access to deploy logs and source code. Table: whole deploy 5:27–6:28 → 4:10/3:57; pre-deploy 79–100s → 51/48s; rollout 84–142s → 52/63s; compress + upload build ~42s → ~25s.
Follow-up to his Mac Mini self-hosted runner post: "No more of this" with a screenshot of GitHub's included usage maxed out (2,000 of 2,000 Actions minutes used, resets in 28 days).
After exhausting the GitHub Actions free tier, built self-hosted runners on Cloudflare Containers

After exhausting the GitHub Actions free tier, built self-hosted runners on Cloudflare Containers. If you switch to self-hosted only after the free quota is used, and you already pay for Workers Paid, the overage looks cheaper than GitHub.
GitHub CI bill went from $0 to $380/month and was heading toward $800 in October
By Jan Wilmake · @janwilmake · Oct. 2, 2026
GitHub CI bill went from $0 to $380/month and was heading toward $800 in October. Cause: coding agents push ~300 times a day and the test suite grew 5x since August. Fix: no CI on PRs; dev only builds and deploys staging; full tests run nightly and on the release PR. New bill: ~$0.
Responding to "slop grenade" chatter: great teams treat huge exploratory PRs as throwaways — assume they'll be closed, not merged. Use them to explore architecture, blast radius, product feedback, and APIs; the mergeable PR can (and often should) be rebuilt separately. Goes further: non-maintainer PRs should be closed by default and kept only as references for future humans and agents.
GitHub Product (Stacked PRs) announces the async merge API is generally available

GitHub Product (Stacked PRs) announces the async merge API is generally available — for programmatic merges by humans or agents. Can merge individual/stacked PRs, add to a merge queue, or merge directly. Changelog: https://github.blog/changelog/2026-10-01-github-async-merge-api-generally-available/
Tongue-in-cheek reply to Flo Crivello (@Altimor): when CI is the top bottleneck and spend is "stratospheric," kache's suggestion is simply "don't run CI." Quotes Altimor's post about CI bottlenecking engineering teams including Lindy.

Reply: move many GitHub Actions checks into pre-commit and pre-push hooks so CI does less; agents can run those hooks, fix issues, and uphold codebase rules. Pair with Turborepo remote caching to cut cost materially.
