HN Engineering Weekly — Week 25, 2026

Fifty-nine posts cleared 100 upvotes this week (down from 130 in Week 24). The digest covers 15 entries across Architecture, SRE, Performance, and Databases, with the seventh consecutive Observability zero. Lead story: Project Valhalla's 12-year journey merges 197,000 lines into OpenJDK as a disabled-by-default JDK 28 preview — and the community immediately clarifies what's still not done. Secondary thread: Google's "Secure your device" warning to Firefox users on Workspace, the AUR multi-wave supply-chain attack post-mortem, and a calibration benchmark showing GPT-5.5 hallucinates at 3× the rate of MIT-licensed GLM-5.2 on the same test.
