The silent retry bug killing ASP.NET Core reliability (and how idempotency keys save you)

41+ min ago   (384+ words) If you’ve spent any time working with distributed systems in C# and ASP.NET Core, you know the drill: network calls fail, timeouts happen, and services become temporarily unavailable. The standard advice? Use Polly. Add a retry policy. Make it…...

Two things nobody was watching

38+ min ago   (331+ words) OpenSpec Workbench's whole pitch is watching an agent while it works. Two small fixes this week are about the product not watching itself closely enough - one where cleanup quietly stopped, one where a number was arriving the whole time and…...

Node.js Feature Flag Rollouts: Stable Bucketing for 10% Notification Releases

1+ hour, 17+ min ago   (621+ words) The least complex useful design is one percentage, one documented hash rule, and one SLO guardrail. Do not call a random-number generator on every request. Do not start with an experiment platform if the operational question is merely whether the…...

700 Skills, 0 Governance: The Missing Layer in Agent Skill Stacks

1+ hour, 13+ min ago   (273+ words) Today's GitHub Trending surfaced a pattern that's been building for weeks: agent capabilities are stacking up at an accelerating rate, but the governance layer isn't keeping up.
