My Posts X Oct 2026 Part 5

From x.com/rauchg

In the weekend of October 18‑19 2026 I posted a handful of X updates that mixed humor, product advocacy, and technical demos.

  • Decision: Remove most harness features because they are unnecessary; this aligns with the stance that Claude code worktree tools should also be removed.
  • Fact: .co domains are “.com‑like, shorter and usually more available.”

These posts also included a tongue‑in‑cheek TLD‑vertical humor list mapping exotic TLDs to countries or concepts, and a note about Epic’s new “agent‑browser snapshot‑delta” feature.

  • Fact: The Roadster demo rebuilt on AI Gateway using the deep‑seek‑v4.1‑flash‑1019‑fast model cost 30 cents.
  • Fact: Tim Sweeney reported his Unreal Engine 1 work split as ~30 % deep coding and ~70 % typing/refactoring.
  • Decision: Promote Vercel AI Gateway as the primary way to run business‑critical agents, citing its transparent session metrics, cost control, and data ownership.
