Open source shows what becomes possible when users can also become developers—and why that freedom matters.Wed, 16 Sep 2026 00:00:00 GMTAI & SoftwareOpen Sourcehttps://zhaozhixu.github.io/writing/programming-languages-between-c-and-lisp/https://zhaozhixu.github.io/writing/programming-languages-between-c-and-lisp/C and Lisp are the two great mountains of programming. Other popular languages build bridges between hardware control and the heights of abstraction.Sat, 15 Aug 2026 00:00:00 GMTProgramming Languageshttps://zhaozhixu.github.io/writing/good-taste-makes-special-cases-disappear/https://zhaozhixu.github.io/writing/good-taste-makes-special-cases-disappear/Linus Torvalds’s linked-list example shows how a better abstraction eliminates special cases—and why that matters for the code our AI agents write.Sat, 08 Aug 2026 00:00:00 GMTProgramming LanguagesAI & Softwarehttps://zhaozhixu.github.io/writing/pyvivo-live-programming-in-python/https://zhaozhixu.github.io/writing/pyvivo-live-programming-in-python/Inspect, evaluate, patch, and roll back code inside a running Python process.
