Give Your Agents a Memory That Lives on Your Machines: Qdrant vs Weaviate vs pgvector
AI agents without persistent memory re-derive everything on every run. A number-backed comparison of the three self-hostable vector stores — plus the per-tenant scale ladder that picks pgvector as the default and Qdrant as the escape hatch.
Sidero Omni Wants to Deploy Your Apps Too: Where Cluster Management Ends and a Git-Push PaaS Begins
Sidero Labs plans to add application deployment to Omni, its Talos fleet manager. A row-by-row accounting of what that changes, what stays hand-built, and why a fleet manager with deploy features still isn't a git-push PaaS.
88% of AI Agent Pilots Never Reach Production — the Gate Is Deployment Infrastructure, Not the Model
IDC puts the enterprise AI pilot failure rate at 88% and blames deployment readiness, not models. A control-by-control gap analysis of SSO, audit logging, secret scanning, PR gates, license policy, sandboxing, and runbooks against a Render-compatible git-push PaaS with MCP.
Argo CD 3.3 PreDelete Hooks: Stop Tenant Teardowns From Leaving Orphaned Wrecks
Deleting an app-of-apps tree can orphan PVCs, DNS records, and whole namespaces — or deadlock for 45 minutes. Argo CD 3.3's PreDelete hooks gate teardown on a Job that must succeed first. Tabled here: the three failure modes, a working hook, four gotchas, and a Flux fit check.
Argo CD vs Flux in 2026: 23,100 Stars vs 8,180, and What the Split Means for Your Cluster Fleet
Argo CD leads Flux 23,100 stars to 8,180, with roughly 60% vs 11% GitOps share in 2026 analyses. The gap is architecture — centralized console versus decentralized controllers — tabled here with a decision rule for Cluster-API fleets.
Hetzner Plus Scaleway: What a Second Cluster API Provider Really Costs a Self-Hosted PaaS
Scaleway's CAPS gives a Cluster API fleet a second EU-native target with hourly H100-class GPUs Hetzner doesn't sell. Here is the verdict table, the both-sides breakeven math near 48% utilization, and the five ops line items a second provider adds before you adopt it.
Carbon-Aware Kubernetes Scheduling Works in the Lab — Here's What It Takes on Rented Hardware
GreenK8s cut scheduler energy use 39% with its own solar array and Google shifts jobs across continents — a single-region fleet on rented racks can only shift in time. This post maps the published results to their lab conditions and lays out the four-step version worth building: meter with Kepler, cut idle with kube-green, gate one batch queue on a carbon forecast, and write the tenant contract.
The Tenant Domain That Didn't Renew: cert-manager vs Gardener vs certctl for Per-Tenant TLS
One certificate per tenant collides with Let's Encrypt's 50-per-week ceiling fast. A concrete comparison of cert-manager, Gardener cert-management, and certctl on challenges, secret distribution, and renewal failure modes — plus which one a self-hosted PaaS should default to.
Your PaaS Quietly Reweighted Every Tenant's CPU: The cgroup v1-to-v2 Conversion Kubernetes Fixed in January 2026
Moving a node to cgroup v2 silently cut a 1-CPU pod's priority to a weight of 39 against the default 100. How the January 2026 quadratic fix restores fair share, what stays transparent, and a four-check audit for your fleet.
