Self Improving Agents in Software Engineering
How are you teaching your agents? Are they learning on their own? Does that lead to better results? Listen to @prathameshsonpatki7217 talk about our experience running agents in production for the last 8 months that self improve!
High Cardinality in ClickHouse at Scale: What Actually Breaks
ClickHouse swallows high-cardinality telemetry at ingest, then breaks at query time weeks later. Here is what fails, and how we keep it fast in production. Prathamesh works as an evangelist at Last9, runs SRE stories - where SRE and DevOps folks share their stories, and maintains o11y.wiki - a glossary of all terms related to observability.
ClickHouse LowCardinality: When It Helps and When It Hurts
ClickHouse LowCardinality cuts storage and speeds up queries on low-cardinality columns, but backfires on trace IDs. How to tell the difference.

Zero-Code OpenTelemetry for Vert.x
Drop a JAR on the JVM. Get distributed tracing, RxJava context propagation, log-trace correlation, and Vert.x internal metrics. No code changes. No Maven dependency. Java 8–21. Inside the design of last9/vertx-opentelemetry v2.3.4.

Stop ECS Containers From Collapsing Into One Service in OpenTelemetry
Why ECS containers collapse under service.name = aws_ecs and how to fix it for both EC2 launch type and Fargate, including the resource-vs-log-record pitfall that quietly breaks log filtering.

Kubernetes Monitoring Tools: What Actually Works at Scale
What actually works for Kubernetes monitoring at scale — not what looks good in a vendor demo with a five-pod cluster.
How to Test SQS Workflows Locally with LocalStack and OpenTelemetry
LocalStack lets you run SQS, Lambda, and S3 locally in Docker — but there's a hidden trap: OpenTelemetry's default AWS propagator doesn't work with free LocalStack. Here's how to set up end-to-end local testing with working trace propagation.

End-to-End Trace Propagation Across SQS and Lambda with OpenTelemetry
SQS doesn't propagate trace context automatically. You instrument both sides, deploy, and get two disconnected traces. This post shows how to wire them into one waterfall — and the ESM format gotcha that silently breaks it every time.
