Docker Hub's Unauthenticated Pull Limits Are Still 100/6hr: When a Self-Hosted Registry Actually Pays Off
Docker Hub still caps unauthenticated pulls at 100/6hr and free accounts at 200/6hr in 2026. A concrete threshold for when a CI fleet should authenticate, pay for Pro, add a pull-through cache, or run its own registry.
E2B Grew 375x to 15M Sandbox Runs a Month. Here's What the Sub-500ms Bar Actually Costs to Clear Yourself
E2B's sandbox volume grew 375x in a year, setting a sub-500ms boot bar for AI agents. Here's what that latency actually decomposes into, and how a Kubernetes-native fleet on owned hardware clears it with Kata Containers instead of rebuilding E2B's control plane.
GitHub Wobbled Three Separate Times in Eight Days: What Owning No Runner Capacity Costs
Three unrelated GitHub subsystems failed independently within eight days in July 2026. A concrete accounting of what broke, why that's a different risk shape than one outage repeating, and what actually changes when the build step and deploy target run on owned infrastructure instead.
Ingress-NGINX Retired in March 2026 — Here's Exactly What Ingress2Gateway Migrates, and What It Doesn't
Ingress-NGINX officially retired in March 2026. Here's the annotation-by-annotation breakdown of what Ingress2Gateway migrates cleanly to Gateway API, what it can't touch, and why the gaps are riskier for a multi-tenant fleet than a single app.
Kubernetes Turned Off Its Own StatefulSet Speedup: The Real Status of maxUnavailable in 1.35/1.36, and the Quorum Math for 1.37
Kubernetes 1.35 shipped StatefulSet maxUnavailable as beta-and-on-by-default — then a rollout-deadlock bug got it flipped back off within the same release cycle. Here's the verified current status, plus the quorum math for when it's safe to raise it.
Nutanix Ships NKP Metal: A Hyperconverged Giant Bets on Bare-Metal Kubernetes
Nutanix, a $2.8B-revenue HCI vendor built on its own hypervisor, just shipped bare-metal Kubernetes as a flagship product. Here's what NKP Metal actually costs, what it doesn't replace, and why it's independent validation for the Cluster-API thesis.
AMD SEV-SNP Comes to Bare Metal: What Hardware Memory Encryption Buys a Multi-Tenant Fleet That Namespaces Never Could
OVHcloud's Scale 2026 bare metal and AWS Dedicated Hosts both shipped AMD SEV-SNP in 2026, at very different prices. Here's what hardware memory encryption actually closes that container namespaces can't, what it costs in dollars and throughput, and who genuinely needs it.
The 2026 'PaaS-First' Reversal: What Hacker News Gets Wrong About Owning Your Kubernetes Cluster
Hacker News sentiment flipped from 'you don't need Kubernetes' in 2024 to pitching Kubernetes-without-a-platform-team products in 2026 — but the PaaS-first argument conflates hand-operated Kubernetes with vendor lock-in PaaS, missing the option that actually removes the toil: Cluster API-based ownership.
Java 26 Will Never Be Paketo's Default — What That Says About the Treadmill a Buildpacks Platform Runs Forever
Paketo added Java 26 support in July 2026, but under its own RFC #0014 math, Java 26 will never be the default — and gets dropped the moment Java 27 ships. A concrete accounting of the version-tracking treadmill a buildpacks platform runs forever, and what a Dockerfile-only platform pushes onto app authors instead.
