• REA: asking your coding agent how someone else's app does it — Oct 14, 2026
  You see a feature in an app and wonder how it works. REA is an open-source tool that lets a coding agent like Claude Code answer that question by inspecting the app itself, with no source code. What it is, how it works, what its case studies actually show, and where the legal and practical lines are.
• 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 didn't get backpropagation the first time. Here's the version that finally made sense — Sep 16, 2026
  My notes on Andrej Karpathy's two-and-a-half-hour micrograd lecture, the first course of my self-made bachelor. What a derivative really is, how backprop works by hand, the bug everyone hits, and a training loop in about twenty lines.
• 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.
