  How Libraries Run Rust Inside Python (with PyO3)

  Every time you validate data with Pydantic v2, the data-validation library most Python apps reach for, a Rust extension does the work. Its core, pydantic-core, is built with PyO3, the same toolchain we'll use here.

  Why Learn to Code If AI Can Code? 6 Reasons

  Stanford's Chris Piech runs Code in Place, an intro programming class with 17,000 students and over 1,000 teachers. They've run it both before and after Cursor and Claude Code arrived, and enrollment basically doubled. It turns out that more people, not less, want to learn to code now that AI can write it.

  Database-Driven RBAC with FastAPI and Azure Entra ID

  This came out of a coaching project: a FastAPI service backing a geotechnical database. We use Azure Entra ID for authentication, but we needed role-based access control (RBAC) granularly per endpoint and across different user roles. It turned into an interesting sprint where we designed it so that role changes did not require code changes.

  Guardrails Protect Your Codebase. What Protects Your Judgment?

  Cal Newport's On AI Coding and Its Discontents lands on an uncomfortable point: the speed AI gives you is paid for with the thinking that made us good engineers in the first place.

  Read code instead of writing it and you get passive recognition where you used to have an active model of the code.

  Judgment: The Skill AI Can't Give You

  Every time I hear the phrase coding is solved, I worry about where this industry is heading. Yes, AI writes the code, you review it, ship it, move on. Is there still value in writing the code yourself and going deep into the problem? Yes, and I think it matters more than ever.
