Infecting the Steam Link with NixOS
While rummaging through my closet the other day I discovered a [Steam Link](https://en.wikipedia.org/wiki/Steam_Link Hardware_device) I had bought on flash sale way back in 2018 still dutifully humming away all these years later. It occured to me that having an always on low power Arm device with Ethernet, WiFi, Bluetooth, and several USB ports would be handy, so thus began my journey to get NixOS running on the Steam Link.

When to choose x86-64 vs aarch64
Not all cloud vCPUs are created equal. When you create a PlanetScale Postgres or Neki database, you have to choose between `aarch64` (ARM) and `x86-64`. Two clusters on different architectures can have the same vCPU count and RAM, yet perform very differently. It's worth understanding the implications, since you can't easily switch the CPU architecture on your cluster later. x86 grew up on the desktop, prioritizing backward compatibility and performance. It began at Intel in 1978 and IBM’s…
