  1. Worker Backpressure (Part 1)

    Canva added a lightweight, local backpressure loop to its queue worker library that monitors per‑message success/failure, computes a backoff factor against a configurable failure‑rate set‑point, and throttles the worker’s concurrency. In two real incidents the mechanism kept failure rates under 2 % fleet‑wide, limited DLQ growth to a handful of messages, and maintained throughput without manual i…

  2. PhysStream: Streaming Physics-Grounded Video Generation with Structured Scene Memory and Fine-Grained Motion Control

    PhysStream introduces a two‑stage autoregressive video generator that uses online‑derived positional and tracking maps (structured scene memory) and sparse velocity‑increment signals to enable fine‑grained, physics‑grounded control of multi‑object tabletop scenes. It cuts motion distribution error by 33 % and trajectory error by 12 % versus strong baselines, and wins 85 % of human preference test…

  3. The Shadow Factory: Why Your CI/CD Sprawl is About to Move Faster Than You Can Think

    The article warns that unchecked CI/CD sprawl— orphaned pipelines, hard‑coded secrets, and permissive runners— creates a hidden attack surface, and that AI‑driven agents will amplify the problem. It recommends a governance layer with real‑time inventory, policy‑as‑code, and AI guardrails to bring the software factory under the same security rigor as production.
