Eric Chou's AI Networking Cookbook inspired me to capture some recent thoughts I've had about using LLMs in the #homelab at https://kd9cpb.com/2026-neteng-homelab. While it’s impossible to predict the future, I couldn’t help but notice how a 20+ year old Fry's Electronics advertisement is a perfect reminder: technology evolves, but some things remain the same!
Thoughts on AI in a 2026 NetEng Homelab - Tom Costello - KD9CPB

Where does AI fit into NetEng Homelabbing these days? A 2005 Fry's Electronics ad is more relevant to that answer than you might think!

Upgraded QTH Roof & Feedlines - Tom Costello - KD9CPB

My four rooftop antennas on the custom PVC mount were good, but with some cabling & grounding improments, they're now great!

Had a ton of fun helping to write https://dl.acm.org/doi/10.1145/3626203.3670531 about all the RFC8925 fun we had at SC23, come join us at #SC24 to check it out in-person!

Had big plans to update https://kd9cpb.com/linux for #raspberrypi 5 & debian bookworm #hamradio fun, but I should really do spring house cleaning & gardening instead. Made a tiny update, but learning to accept my old blog posts are fading into obsolescence 🙃

Had some fun getting #FT8 magic onto a nearly 20 year old PC at https://kd9cpb.com/wsjtx. It sure looked good running on the square monitor!

WSJT-X on a 20 year old computer running AntiX Linux 23 - Tom Costello - KD9CPB

WSJT-X can run on almost any PC made in the last decade, but what about a PC from two decades ago? It kinda works!

I'm not going to create much #homelab and #hamr content in 2024, but what I do end up clicking "publish" on will be a good time :)

Check out what I'm thinking and my winter #hamradio antenna situation at https://kd9cpb.com/2024-gameplan

The chimney-top PVC antenna rig is working well, no winter issues! Here's what I have up my sleeve for ham radio & homelabbing in 2024

It's a Festivus Miracle! Migrated my blog to an OrangePi5 via Cloudflare Tunnel this afternoon, full write-up at https://kd9cpb.com/orangepi5

Can't believehow good Cloudflare free accounts & cheap single-board computers have gotten over the past decade, what a time to be alive!

Moving this blog to an OrangePi 5 + Cloudflare Tunnel on Debian 12 (with WSJT-X!) - Tom Costello - KD9CPB

running kd9cpb.com is a hobby, why should I pay monthly webhosting when I can do it on my Orange Pi 5 via a free Cloudflare Tunnel?
