God Packages and Other Slow Failures
Structural ratchets for AI-assisted Go, six months into make verify

The agent found every page certified unreachable. Links cut search cost and keep working when search is off; they do not change what it reaches
2026-08-20
142Knowledge Pollution: Verification Displacement, Capability, and the Price of a Curation Gate
A wrong note that passed review spread only where the agent could have checked it, and only on Haiku 4.5: 16 of 24, against 0 of 24 on Sonnet 5 and Opus 5

134A Multi-User Data Lab: JupyterHub on Your Platform
Self-hosted notebooks for the whole team, on Keycloak SSO, wired to the lakehouse and every data source you own

133IoT Ingest You Own: MQTT With Mosquitto on Kubernetes
Lightweight device messaging into the platform, bridged to Kafka, with the Mosquitto 2.0 change the old guides miss

132See the Whole Platform: Prometheus, Grafana, Loki, and OpenTelemetry
Self-hosted observability for everything you built, on the open standard instead of a per-host APM bill
2026-07-27
131When Do Agents Use Stored Knowledge?
A benchmark that killed its own hypothesis: strong models re-derive what they can check, and a weak model trusts a stale note over the evidence in front of it
2026-07-26
130Cilium: One eBPF Data Plane for Networking, Security, and Encryption
The CNI that replaced Weave Net, kube-proxy, and a hand-rolled WireGuard overlay with a single component

129containerd Without Docker: the Runtime Under Your Cluster
The container runtime the kubelet actually uses, and how to configure and debug it now that the Docker shim is gone

128Does a Semantic Knowledge Layer Make an Agent Measurably Better?
A reproducible benchmark: 42.7% to 98.7% on knowledge-trap questions, and a platform that learns from empty
2026-07-22
127GitOps: Git as the Source of Truth for Your Cluster
Argo CD and Flux, the deployment half the 2020 book left out, with manifests reconciled from a repo you own
2026-07-21
126Build Images Inside Your Cluster, Without the Docker Socket
Rootless container builds in CI with BuildKit, and where supply-chain guardrails belong
2026-07-19
125Your Git Forge Belongs on Your Cluster: Forgejo
Self-hosted source, CI/CD, and a registry, on the lightweight fork that left its for-profit parent

115When Your Tools Lie to the Agent
I drove my own platform as a real client and told it to find every place a tool said one thing and did another. A case study in MCP SDLC.
