How they work

Yosi works in public: experimenting with plain HTML, building self-hosted web tools, and turning technical questions into essays and case studies. The rhythm is hands-on and iterative, with launches followed by notes about what worked, what broke, and what deserves a closer look.

    The Small Project Season

    The channel opened by sharing lessons from years of software work, then moved quickly into small personal builds. Great Walk launched as a plain HTML site, while a separate hardware experiment documented the messy reality of making things.

    Writing Meets AI

    Yosi’s notes widened into essays, AI commentary, and practical learning resources. Their writing about large language models reached Hacker News’ front page, while posts on Opus 5 and AI engineering kept the discussion close to the tools themselves.

    Ship It, Then Study It

    The channel returned to hands-on web building with an Among Us recreation, TeleLite, See Through, and a growing personal site. By October, the theme had sharpened: build in public, then explain the decisions through detailed case studies.

Fresh from the channel.

Opening 350+ webpages at the same time to find and analyze phishing sites pretending to be PayPal. I’ll try CBE next. I’ve been seeing CBE scam links posted on LinkedIn.
