Hetzner Wants 50 Hectares in Bavaria to Build Its Own Power Plant: What Vertically Integrated Solar Would Mean for Your Hosting Bill

Hetzner is evaluating 50 hectares in Bavaria for a solar-powered datacenter, the second step after its HT Clean Energy solar venture — what's actually built versus still a land inquiry, and why grid-connection queues and volatile industrial power pricing, not marketing, are driving it.

Highlight.io's Shutdown Is a Governance Checklist Your Observability Stack Needs

Highlight.io shut down as a standalone open-source tool on February 28, 2026 after LaunchDarkly acquired it. A five-question governance checklist backtested against Highlight itself, then scored against GlitchTip and SigNoz.

The Jscrambler npm Backdoor Beat npm's 3-Day-Old Fix — What That Means for Your Build Pipeline's Secrets

A compromised Jscrambler npm release beat npm 12's new install-script defaults within three days, stealing CI credentials and AI tool configs. Here's the build-pipeline architecture — platform-enforced script policy, egress-denied sandboxes, ephemeral scoped credentials — that actually closes the gap.

IPVS Is Deprecated in Kubernetes 1.35: What Actually Changes When kube-proxy Moves to nftables

Kubernetes 1.35 deprecates IPVS proxy mode in favor of nftables. Here's the concrete before/after — the load-balancing algorithm you lose, the conntrack behavior shift, and a node-by-node rollout sequence — for migrating a self-hosted fleet's kube-proxy before the next cluster upgrade.

Dynamic Resource Allocation Comes of Age in Kubernetes 1.36: Scheduling GPUs Declaratively Instead of Renting a Managed Tier

Kubernetes 1.36 matures Dynamic Resource Allocation's GPU-scheduling features right as Fly.io kills its GPU line — here's what DeviceClass and ResourceClaim actually replace, and the real cost math between owning a Hetzner GPU and renting one by the second.

Kubernetes Just Deprecated externalIPs. Here's the Exact Migration Path for Bare Metal

Kubernetes 1.36 deprecated Service externalIPs over a security hole the project never patched. Here's the exact four-stage removal timeline and the commands to migrate a bare-metal fleet to MetalLB before the default flips in 1.40.

Kubernetes 1.36 Ships Gang Scheduling In-Tree: What It Actually Buys an AI-Agent Batch Fan-Out

Kubernetes 1.36 Ships Gang Scheduling In-Tree: What It Actually Buys an AI-Agent Batch Fan-Out

Kubernetes 1.36 ships PodGroup and Workload APIs in-tree, letting the scheduler gang-schedule a multi-pod fan-out atomically. Here's exactly what the five alpha feature gates do, what they replace Volcano/Kueue for, and how far alpha still is from safe for tenant workloads.

Your Kubernetes Install Doesn't Have a Finish Line — And More Docs Won't Give It One

Why self-hosted Kubernetes installs for AI platforms stall for weeks, and why owning the node fleet with Cluster API fixes what better documentation can't.

Kubernetes 1.35 Killed the CPU Restart Tax. Memory Still Pays It.

Kubernetes 1.35 Killed the CPU Restart Tax. Memory Still Pays It.

Kubernetes 1.35 made CPU resizes truly restart-free, but memory resizes still restart the container by default. Here's the resizePolicy mechanics, the real constraints, and how a self-hosted PaaS should wire this into its tenant plan-upgrade flow.
