If you’re a Twitter user (and even if you’re not) you may be aware that it was recently acquired by one Elon Musk. You may also be aware that he’s gone on a cost cutting rampage that has left people concerned for the future of the platform as mass layoffs and publicised technical changes have resulted in broken functionality or massive shareholder losses.

There is a Twitter alternative, just one amongst many, called Mastodon. It’s a part of something called the Fediverse; which is a silly word that fundamentally groups a large number of applications around something called the ActivityPub protocol. In brief it’s a well defined method for clients and servers to talk to each other about people and what they’re doing. Which is why, over the last few weeks, Mastodon servers (or instances) have seen a massive spike in new user accounts and usage. People are migrating and instance owners have been scrambling to scale up their infrastructure to cope.

You can always join one of the many instances available, or, like I did you can run your own¹.

If you’re anything like me you’ll have a bunch of IoT smart home devices; if you’re anywhere as cheap as me, a number of those will only work on 2.4GHz networks which makes using the Google Wifi a right pain¹. I did eventually get the devices registered but only after many many repeated pairing/registration attempts. Presumably they would randomly latch onto the 2.4GHz network and be able to complete the process but it was frustrating work.

The internet also tells us just how all these cheap devices are realistically insecure and that you should be keeping them on a separate network so with that I decided to upgrade my network gear so I could implement secure things, like VLANs and ACLs and all of that fun stuff but I was using a Google WiFi mesh and although it did the job pretty well it just didn’t offer any power user features at all - primarily it didn’t do VLANs, or even more than one WiFi network which meant getting any sort of separation from my potentially badly behaved devices was next to impossible.

So I upgraded the hardware.

If you want to run Pi-hole on your network but not have the entire family grumble that the internet isn’t working when you need to reboot the machine it’s running on then you’ll need to run two Pi-holes. To run two Pi-holes properly they need to a) be on separate machines (I use my main homelab server and a RaspberryPi) and b) be configured on your client devices appropriately.¹

If you’ve got all that working but have been getting annoyed that adding any new service means duplicating manual configuration steps in a clunky Pi-hole web interface then you’ll likely have been searching for some sort of automation to handle it. Fortunately I came across a Terraform provider for Pi-hole that got me most of the way there. I just needed to put together a playbook/plan for it.

So with that. I present STPFMMP (Simple Terraform Playbook For Managing Multiple Pi-holes)

Welcome to the second part of a multipart series where we setup a Home Assistant instance in Docker. We’ve already installed Ubuntu server on Raspberry Pi and have an instance of Portainer running. If you want to see how we got this far then check out part 1

In this instalment we’ll be solidifying how we configure our environment. We’ll also be setting up Traefik to act as the frontend to our web applications and getting our Raspberry Pi a permanent home on the internet, and we’ll revisit Portainer so that it works in our new Traefik driven world.

I decided, the other day, to pull an early 2008 Macbook Pro from it’s venerated “I’m too emotionally attached” spot in my tech hoard and breathe some new life into it. This post details the saga of making that happen.

The laptop in question is an 15" A1260 Macbook Pro 4,1. It was the last model produced before Apple went all machined-one-piece with their chassis technology and it has been loved. It’s lifetime has seen a 2GB RAM upgrade (its maximum) and a hard drive replacement, it now sports a 500GB Seagate Hybrid drive¹. At some point in the recent past I even had to bake it in an oven as the on board Nvidia 8600M graphic chip had seen fit to melt it’s own connections to the motherboard.
