My home Kubernetes cluster started out on a Core i7-920 with 8 GB of memory.

Upgraded to 16 GB memory

Upgraded to a Core i5-2400S

Upgraded to a Core i7-3770

Upgraded to 32 GB memory

Recently Upgraded to a Core i5-7600K

I think I’ll stay with that for rather long…

I did however add 2 Intel NUCs (gen 6 and gen 8) to the cluster to have a distributed control plane and some distributed storage.

The depth perception also makes quite a difference. The side of your face can clearly be seen in a mirror to be the side of your face, but depending on lighting, the side of your face can look as if it’s part of the front of your face in a picture as you don’t have the depth perception. The result is that photos make you look fatter than your mirror image would.

Nope, but I trust the ones that lack the hardware for dialing home.

But generally I don’t buy devices unless I have reason to trust them.

As the other poster said, both Zigbee and Zwave devices do not talk to the Internet. They can’t even connect to your Wi-Fi anyway. They need to connect to a device that acts as a router but specifically for Zigbee or Zwave, usually called a Hub or Coordinator.

There’s many different hubs around. Many commercial ones do indeed connect directly to the WiFi and therefore internet. But nothing is stopping you from buying a USB Dongle Hub with open source firmware and plugging it into a Raspberry Pi, if you want to eliminate the potential spying.

The Zigbee and Zwave networks inherently cannot communicate with the Internet. So the only risk of spying is if you installed something in the Raspberry that spies on you.

Both Philips Hue and IKEA Trådfri and many other vendors simply use Zigbee, which means you can bring your own Hub and completely eliminate the risk of spying.
