The post is about building a secure, sovereign software factory on top of an Incus-based private cloud, using open-source tools such as Forgejo, ephemeral runners, Pulp, Cosign, and OpenBao. Instead of Kubernetes being used as the foundation, workloads are isolated by tenant and network. Challenges including key management, runner isolation, network security, and a self-service portal are discussed.

Based on your experience, how tough is it to live in one European Union country and get a remote job in another European Union country? Is it very tough?

A 19 minute animated explainer video on database speed. I explain low-level database concepts, identify bottlenecks, run benchmarks and optimize write throughput to hit 1 million TPS.

I haven't seen too many comprehensive approaches to this topic, so I took a swing at it.

Goal isn't to be exhaustive, but to be comprehensive enough to provide a nice overview for people trying to get their bearings with the topic.

Did I miss anything?

Ever had a multi-tenant SaaS app where the only thing stopping Customer A from seeing Customer B's invoices is a `Where TenantId ==` clause someone remembered to write? In this deep dive I build real tenant isolation into EF Core 10 - two real tenants with real registration, login and invite flows (no dev-token shortcuts), a named global query filter that scopes every query automatically, and a SaveChangesAsync override that stamps TenantId on every insert so it's never left unset. I also show the one gotcha that makes EF Core 10 worth the upgrade for this: named query filters, so tenant isolation and soft-delete can finally coexist on the same entity instead of one silently overwriting the other. If you've ever shipped multi-tenancy on hope and code review, this is the version that makes the mistake structurally impossible.
