Developer replaced nearly every standard Linux desktop tool with custom-built software in weeks, using Claude Code and Rust, arguing BYOS is now genuinely feasible.
Key Takeaways
Stack split into two layers: CHasm (pure x86_64 assembly, no libc) for low-level display/input, and Fe2O3 (Rust on a shared TUI lib called crust) for applications.
Replaced vim after 25 years with a custom modal editor called scribe, built in 72 hours via Claude Code; includes HyperList syntax, AI prompt integration, and persistent cross-session registers.
Full replacement table: i3-wm, kitty, zsh, mutt, ranger, Google Calendar, and more all swapped for bespoke tools; only WeeChat and Firefox remain third-party.
Core argument: AI-assisted coding and Rust have dropped the cost of building personal tools by orders of magnitude, turning year-long projects into weekends.
BYOS payoff is eliminating configurability surface area and committee-driven defaults entirely, producing smaller and faster software shaped to one workflow.
Hacker News Comment Review
Minimal discussion so far; one commenter questions whether the post itself was human-written, noting it reads like a human overfitted on GPT-4o or Claude.
The other commenter links the public repo (github.com/isene/chasm) but expresses skepticism about the motivation without elaborating.
