P.01macOS 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.02Firmware 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.03Bun 1.4 is the first stable release on the Rust runtime, adding browser automation, image and markdown APIs, and real speedups. Why it split opinion.
P.04Kitesurf is a browser runtime with no UI or tabs, built for AI agents to load pages and extract HTML. It claims 3-7x less CPU than Chromium. When to use it.
P.05A Merkle tree proves a piece of data belongs to a large dataset, or finds exactly what changed between copies, without reading all of it. How, and where.
P.06PostgreSQL 18.6, 17.11, 16.15, 15.19, and 14.24 fixed 28 CVEs on August 13, 17 of them CVSS 8.0 or higher. Which matter, and who's actually exposed.
P.07cargo-audit finds known CVEs after the fact; cargo-vet checks trust before you upgrade. Setup for both, and which catches an arrayref-style attack.
P.082026 rate data shows two opposite trends: AI-assisted competition pushing junior rates down while seniors who can supervise AI output command more than ever.
P.09Four AI code review tools, four tradeoffs. What differs between Copilot's built-in review, CodeRabbit, Greptile, and Qodo past the marketing, and seat costs.
P.10The W3C Design Tokens group shipped a stable exchange format backed by Adobe, Figma, and Google. What it standardizes, and how to migrate an existing setup.
P.11Deployment frequency, lead time, change failure rate, time to restore. What each measures, the tiers that separate elite teams, and where teams misuse them.
P.12React Router v8 shipped as a deliberately boring release. What the version bump requires, what the codemod handles, and the three things that catch teams.
