How I work

  1. 01

    Isolate

    Find the layer the fault lives in before touching anything: cable, route, port, certificate, config.

  2. 02

    Fix

    Fix it there, not three layers up where the symptom showed.

  3. 03

    Script

    Turn the fix into automation so the same ticket never needs a human twice.

  1. #1 on Hacker News The 'Astra can read and write weights to improve Qwen' post is misleading

    The viral post claiming an AI can directly read and write raw weights to improve Qwen is misleading, as those impressive results actually relied on executing Python code and running the network.

  2. #2 on Hacker News Could a modern chess engine on a Pentium have defeated Kasparov in 1996?

    A modern chess engine running on a 1996 Intel Pentium Pro hardware setup would have easily defeated Garry Kasparov, proving algorithm improvements matter more than raw hardware speed.

  3. #3 on Hacker News Resisting Cognitive Surrender

    Uncritically accepting AI agent output causes technical debt and erodes system understanding, requiring developers to intentionally maintain control, enforce simplicity, and avoid cognitive surrender.
