Cloud, databases, networking, and ham radio

Welcome to my personal technology blog.

I write about the systems I build, break, fix and occasionally understand on the first attempt. My topics range from Oracle Cloud Infrastructure and database platforms to networking, IPv6, OpenWrt and home automation.

You will find practical notes about cloud architecture, high availability, Oracle Multicloud, connectivity, routing and database migrations. I focus on real configurations, useful commands, troubleshooting and the lessons hidden inside failed experiments.

Networking gets a lot of attention here. I explore IPv6, WireGuard, VPNs, OSPF, BGP, firewalling and routing between cloud environments and private networks.

Several articles describe how I connect Oracle Cloud with my home network. Others cover CGNAT, public IPv6 access, OpenWrt routers and segmented networks.

My home network serves as a permanent technology lab. It includes VLANs, DNS, firewall policies, secure access, wireless networks and family-friendly device separation. It also provides a reliable environment for testing ideas before they reach production. Sometimes the test works immediately. More often, a packet takes an unexpected route and starts a new investigation.

Ham radio and HAMNET form another part of the blog. I write about antennas, digital modes, radio networking and the technical links between computers and radio systems.

The articles reflect my own practical experience. I document working solutions, failed attempts, strange behaviour and the configuration changes that finally make things work.

Expect technical details, command-line examples and honest lessons from real projects. This blog is for engineers, administrators, technology enthusiasts and anyone who enjoys finding out why a system behaves the way it does.
