Orthopaedic Injuries
Figured I would start making blog posts on some of my other endeavors and let my blog be more of a smorgasbord of my interests.

Fabric AI Tooling
Decided to abandon the AI when writing this blog post and all blog posts going forward. There’s just something about a consistent writing habit that makes a difference in everyday life. Over the last two weeks I have been playing around with Fabric AI(https://github.com/danielmiessler/Fabric) by Daniel Miessler. It came to my attention when I discovered…

How to Test and Verify QoS in a Cisco Lab Using iperf3
Quality of Service (QoS) is one of those topics that can sound simple on paper but becomes tricky when you test it on real gear. In this post, we’ll walk step-by-step through setting up a small QoS lab using a router, a firewall, and two endpoint hosts — then validating the policy using iperf3. The…

Bipartisan News Digest with Python, Ollama, and Google API
Concept and scaffolding by Francois (grammar edited by AI) Overview I wanted a way to regularly consume news coverage from across the political spectrum—without living inside any one outlet’s bubble. The goal was to build a bipartisan news digest that: An interesting side effect is that this system also generates structured, timestamped metadata about which…

Building a Scalable BGP Lab with Containerlab and FRRouting
In this guide we’ll build a mini ISP-style BGP lab that scales cleanly from a handful of routers to hundreds or thousands — without going insane managing configs by hand. We’ll use: The example here uses 5 core routers and 10 edge routers, but you can turn that into 1000+ edges by changing a single…

Enabling Freeradius in WSL to connect to cisco lab
1. Overview By default, WSL 2 creates a lightweight VM and places your Linux environment behind a NAT. This allows you to access services via localhost on Windows, but it prevents external devices from reaching your WSL instance directly. To fix this, you must configure WSL to use a bridged network interface. That way, WSL…
