Why are nuclear power construction costs so high? Part III – the nuclear navy
This week we conclude our look at nuclear power construction costs. So far we’ve looked solely at conventional nuclear power stations that supply electricity to the grid for residential and commercial use. But civilian power stations aren’t the only sort of nuclear reactor that the US builds. The US Navy has been…

Raspberry Pi WiFi to ethernet bridge
The goal is to connect a non-WiFi computer to a WiFi network using a Raspberry Pi. We will use a Raspberry Pi 4 Model B as a bridge between the non-WiFi computer and the WiFi network. The Raspberry Pi connects to WiFi and shares its connection with other computers over Ethernet. These instructions were only tested and…

Building a home NAS on a shoestring budget with the Rock64 SBC (2018)
I’ve gone through many iterations of a Home NAS over the years. It started with an AMD Phenom based system running in a Norco case with about 8 hard SATA hard drives (4 primary, 4 backup via Rsync). The noise and power consumption of that system was overkill for what it was used for, so I sold it and went to a…

The Limits of NTP Accuracy on Linux
Lately I’ve been trying to find (and understand) the limits of time syncing between Linux systems. How accurate can you get? What does it take to get that? And what things can easily add measurable amounts of time error? After most of a month (!), I’m starting to understand things. This is kind of a follow-on to a…

Ansible vs. Chef (2015)
I wrote an earlier post about evaluating Ansible as an alternative to Chef. So after spending many years with Chef, I’ve found that Ansible is a lot easier to manage with startups. It’s easier to train developers, it’s easier to manage inventory and orchestration, and it works reasonably well on the scale of thousands…

Monitoring My Homelab, Simply
Don’t get me wrong, I understand that they’re essential for large fleets of services with fast-changing software and teams of oncallers working around the clock to understand the complex ways that complex systems fail… but my stuff doesn’t change that often, failures are mundane and low-scope, and I’m the only person…
