P.104macOS 27 deprecates hdiutil and points disk image work at diskutil image. The subcommand mapping, what's missing, and updating a DMG build without breaking CI.
P.105Firmware hiring fails differently from web hiring. The pool is small, the specialisms don't transfer, and the usual coding screen tells you almost nothing.

P.129Braintrust's pitch is that talent keeps 100% and the fee sits with the client. That changes the incentives in ways worth understanding before you decide it is cheaper.
P.130Integration tests that boot every dependency are slow and flaky. Contract testing checks that consumer and provider agree on a shape without either running.

P.151The W3C's updated accessibility evaluation methodology now covers mobile and desktop apps, not just web pages. The five-step audit, applied to a native app.
P.152Almost every queue advertising exactly-once actually gives you at-least-once plus a way to make your handler idempotent. The real distinction, and why.
P.153Pessimistic locking stops one request from starting; optimistic lets both run and catches the conflict at the end. How each works, with SQL, and how to pick.
P.154Soft delete sounds like the safe default, but it quietly breaks unique constraints, foreign keys, and query performance unless you design for it up front.
P.155Full rewrites fail because the business can't stand still for two years, not because the new code is bad. How the strangler fig moves traffic piece by piece.

P.252How to assess a codebase before you buy, inherit, or partner on it: the documents to request, what kills deals, and what turns out to be fixable.

P.276Everyone claims ML experience since the AI boom. The screen that separates people who ship ML systems from people who fine-tuned once in a Colab notebook.
