    Documentation only survives if it lives as close to the code as possible. Good documentation isn’t a single artifact - it’s a small ecosystem of layers, each serving a different purpose.

  • I Spent 30 Days “Vibe Coding” an MVP — Burned $127, Broke Everything, and Still Found Product-Market

    This story was originally published on HackerNoon at: https://hackernoon.com/i-spent-30-days-vibe-coding-an-mvp-burned-$127-broke-everything-and-still-found-product-market.

    I spent 30 days building a financial planning tool for founders by “vibe coding”. Made every mistake possible. Burned through $127 in Replit credits. Got calculations wrong by 20%. Watched 23 "interested" founders become 2 signups.
    But I also learned that:
    (1) AI struggles with precision calculations, (2) founders don't want another spreadsheet—they want advice, and (3) sometimes less is more.
    One founder offered $50/month for the simplified version. That's validation enough to keep going.
    This was a great learning experience for me as I go to be on the other side of the table so to say. I spend time working with founders at accelerators and advising them about getting from zero to 1.
    This was a good opportunity for me to “eat my own dog food”!

  • The Anatomy of a Write Operation

    When you write to a file in Python, the "success" return value is an illusion. Your data hasn't actually hit the disk; it has merely entered a complex relay race of buffers. This article traces the lifecycle of a write operation across six layers: Python's internal memory, the Linux Virtual File System, the Page Cache, the Ext4 filesystem, the Block Layer, and finally the SSD controller. We explore why the OS prioritizes speed over safety and why you must use os.fsync() if you need a guarantee that your data has survived power loss.
