Pinterest Engineers Eliminate CPU Zombies to Resolve Production Bottlenecks

Mark Silvester — Thu, 14 May 2026 10:00:00 GMT

Pinterest identified and resolved CPU starvation issues that affected machine learning training jobs on its Kubernetes-based platform, PinCompute. The engineers traced the problem to an unused Amazon ECS agent, which caused memory cgroup leaks. By disabling the agent, they stabilised performance. This case illustrates the importance of understanding system defaults for effective troubleshooting.

Presentation: What I Learned Building Multi-Agent Systems From Scratch

Paulo Arruda — Wed, 13 May 2026 12:01:00 GMT

Paulo Arruda discusses Shopify’s evolution in AI adoption, moving from simple chat tools to a sophisticated swarm of specialized agents. He explains the transition from massive "all-in-one" prompts to lean, narrow-focused agent microservices that slash task times from hours to minutes. He also shares a future-looking hypothesis on using filesystem-based adapters to solve context bloat.

Article: The Mathematics of Backlogs: Capacity Planning for Queue Recovery

Rajesh Kumar Pandey — Wed, 13 May 2026 09:00:00 GMT

Backlogs in distributed systems are arithmetic problems, not mysteries. This article provides practical formulas for calculating backlog drain time, sizing consumer headroom, and setting auto-scaling triggers. It covers key failure modes — retry amplification, metastable states, and cascading pipeline bottlenecks — plus when to shed load instead of draining.

Article: Time-Series Storage: Design Choices That Shape Cost and Performance

Nirmesh Khandelwal — Tue, 12 May 2026 09:00:00 GMT

Every time-series database makes a set of storage design decisions: how to lay out rows, when to compress, what to partition on. These decisions determine cost and query performance more than the choice of database itself. This article works through those fundamentals from first principles, using widely available tools like PostgreSQL and Apache Parquet to make each trade-off measurable.
