Atlanta and Cobb County join forces to extend the Silver Comet to downtown Atlanta
For several years now, organizers have fought hard to realize the dream of a continuous bike trail all the way from downtown Atlanta to Anniston Alabama.

Below, I’ll describe how and why I’m moving more and more services onto virtual machines (VM). This is better for security because you … Read more
How to limit the possible damage done by docker container malware
For all the docker users out there, I thought I’d share a couple points about managing docker containers on your home server. These are important security issues that get commonly missed. The simple examples you see on the internet for installing docker containers won’t usually mention these things. But they might save your whole system … Read more
My site has moved – hopefully to a more secure home
Whew! It’s been a few intense months. I’ve been too engaged to stop and take note of any of it. But I’m taking a breather here to mention a couple things I’ve been working on and talk about the New Home for this blog and how that fits in. With my DS-1520+ server with its … Read more
