How a Small Update Almost Deleted My Entire GPS History – And What I Learned From It
TL;DR
A hidden TimescaleDB retention policy almost deleted four years of my self-hosted Traccar GPS history. The policy came from the database layer, not from the Traccar config I usually checked. I was able to restore my full history from backups, remove the retention jobs, and stop the silent cleanup. That incident pushed me away from file-level backup thinking and towards a Kubernetes-native PostgreSQL setup with CloudNativePG, Barman Cloud, MinIO, Longhorn, and GitOps. You do not need to copy my full stack to learn from this, but you should make sure your backups are real, restorable, and aligned with the data you actually care about. I’ve been living with self-hosted infrastructure for years: email, messaging, photo storage, home automation, and all the small services that quietly support everyday family life.

Embracing Agile to Foster Self-Organization in Cybersecurity Teams
In the ever-evolving and high-stakes world of cybersecurity, being agile isn’t just a buzzword—it’s a survival skill. Cyber threats evolve rapidly, requiring teams to adapt and respond just as fast. Traditional project management methodologies, with their rigid structures and slow-moving processes, often fall short in meeting these dynamic needs. Enter Agile, a framework initially designed for software development but one that holds immense promise for non-software teams—cybersecurity teams included.

How I Moved My Synology DS920+ VM to an External SSD (And Survived to Tell the Tale)
A journey of SSH commands, coffee-fueled debugging, and one surprisingly cooperative USB drive The Backstory: Why Bother? Picture this: It’s 11 PM. I’m staring at my Synology DS920+, its four drive bays humming softly like a contented cat. But there’s a problem—my beloved Ubuntu VM is gasping for storage space, trapped on the NAS’s internal volume. I could shuffle drives, but that feels like performing open-heart surgery on my data hoard. Then I spot it: a lonely USB 3.0 port.

VPNs: When to use a Virtual Private Network
A Virtual Private Network (VPN) secures your own device from other devices on the same local network. This is done by encrypting all traffic which leaves your machine. After that, only a chosen trusted third party machine can decrypt the traffic again. This machine will usually be hosted by either a service provider or eg. the IT department of your company. In this post, I give you some thoughts about when to use a virtual private network and when you are probably better of not using one.
