• Spec Kit on a project that already exists: the real flow, step by step — Sep 28, 2026
  My first question after installing GitHub's Spec Kit was "do I start with /speckit-plan?" The answer is no. What Spec Kit is, the order of commands for adding a feature to a codebase you already have, what it cost on a real feature on this site, and the three bugs it didn't catch.
• I started losing my words — in both of my languages — Sep 19, 2026
  Eight months of small talk and I could no longer say anything deep, in English or in Farsi. Here is what I think is actually happening, why the second language is not the problem, and the small, boring routine that brings it back.
• Four treasuries walk into a bar: OlympusDAO, NetNet, Standard Reserve and Brim — Sep 17, 2026
  One 2021 idea, one spectacular crash, and three new projects on Robinhood Chain that each say they fixed it. A plain-English tour of treasury-backed tokens, with pictures, a comparison table and the one question that matters: where does the yield really come from?

• I designed my own four-year bachelor — and I'm studying it in public — Sep 15, 2026
  Thirty-six university courses, eight terms, one exam and one real artifact per course. Why a working software engineer built a degree out of free lectures, how the whole system runs, and how you can use it.
• The sniper effect — what launchpads did to Robinhood's chain — Jul 18, 2026
  Robinhood shipped a pristine Layer 2 for tokenized stocks. Within a week, a memecoin launchpad and a swarm of sniper bots owned it. Here's the technical reason that was never avoidable.
