    I had already shared my experience with Antigravity as an AI development environment, covering models, quotas, and basic workflows. But since the launch of Antigravity 2.0 in May 2026, the tool took a leap that changed how I work with code agents. It is no longer just an IDE with a built-in agent — it is now a platform for orchestrating autonomous agents.

  • (2026-05-02) Behavioral Guidelines for Coding Agents

    For years, the Python ecosystem has grappled with the “two-language problem”: we write code in Python for its ergonomics, but when performance becomes critical, we drop down to C or C++. This transition has always been painful, introducing memory safety risks and considerable maintenance complexity. However, we are witnessing a paradigm shift. Rust has become the new standard for building Python infrastructure.
