ChatGPT your Project Docs
I mentioned in my last post that I would start updating practical use cases for generative AI. The first example use case is your project documentation.

Measuring Network Bandwidth using Iperf and Docker
At the heart of any network engineer’s toolkit, are applications that let you peer into the network for performance, congestion and capacity planning. One of the thoroughbreds in the open source network tools collection is iperf. Iperf has been around for a long time. The good folks at ESnet updated the original iperf with new features and what not and …
GoBGP – A Control Plane Evolving Software Networking
If I have talked to you over the past year or two about networking, odds are I have mentioned a project to you called GoBGP. If we have spoken a lot, you are probably sick of me talking to you about GoBGP 🙂 There is a reason, it’s because GoBGP is a missing link in networking that has been for …
Configuring Macvlan and Ipvlan Linux Networking
