VMAF v1: Good Is Not Good Enough

AI Agents For Release Notes And Changelog Automation

Here's a changelog entry nobody asked for: ## v2.4.0 - fix stuff - wip - address PR comments - Merge branch 'main' into feature/checkout - update deps - final fix (for real this time) That's not a changelog. That's a git log with a version number stapled on top. And the people who maintain Keep a Changelog have a name for it that I can't improve on: "Don't let your friends dump git logs into changelogs." The interesting part is the timing. That tagline is from 2014. The problem of turning raw

Scarab Diagnostic Field Test #034 - Prometheus Docker Swarm Label Source Boundary

Target: prometheus/prometheus Issue: prometheus/prometheus#12244 Pull request: prometheus/prometheus#18979 Field Lab record: Prometheus #12244 This field test was about documentation, but not "just documentation."

Microsoft Recall Opt-in Change

Originally published on lavkesh.com Microsoft just announced Recall will ship as opt-in rather than opt-out. That is a complete reversal from the original design, and it matters more than the technical detail itself. It marks a line in the sand for what users will accept from AI features running on their own hardware. Recall is the AI memory feature announced in May as part of Copilot+ PCs. The premise is genuinely useful: your PC takes periodic screenshots of everything you do and uses an on-de
