I was talking to my husband who has been traveling for work to an industrial site, and he sent me a picture that included a "permanent magnetic lifter".

They look like this: https://www.magnet-sdm.com/wp-content/uploads/Permanent-magnetic-lifter.jpg

I had never heard of these and wondered how they worked - how is it possible to "turn off" a magnet without electricity??

I found a video where someone explains how this is possible: https://www.youtube.com/watch?v=PMma3OJUHhs

I got one of the smallest of these as a gift for my husband. This tiny thing is strong enough to lift 68kg. It's strong enough to lift me!

Headphones! I've recently learned that headphones are the most cost effective way to enjoy the audiophile experience. They even make headphone specific amplifiers. You could probably spend around 300 dollars on a good headphone set up that would cost you in the 1000's speakers-wise.

And honestly I'm surprised it took me this long to realize just how awesome musoc sounds in them, all while not pissing off wife with speakers blaring in the basement.

Home Assistant, who knew home automation could be fun (except trying to integrate a nest thermostat who knew that would be the issue)

I learned how to set up and use HAProxy. I’m using it as a load balancer in front of my email service so I can update VMs without any downtime. It’s incredibly cool how versatile it is, but setting it up feels like nailing jello to a tree.

I managed finally to set up several VMs and connect them into kubernetes cluster so I can learn that tech properly. I come from one or two layers below, I've been Linux admin who touched Ansible and did some open stack ocherstration but never had opportunity to go higher due to the project specific issues. So here I am, in theory a senior, learning popular tech which is required from juniors. Humbling experience, and NGL after 30 it's getting harder, but it's still fun.

For details if anyone is interested I made six vms, one serves haproxy, two are worker VM, three are controller. They are connected into network, and I run kubespray to create cluster from that. All localhost which is nice. I make small readme on it to later format and put ^^ I had issues with set up like WSL having python3.8 and kubespray refusing to find pip deps, which I figure more people might encounter if they experiment. And as admin, for me it was always the greatest hussle to setup the toolset, all later steps are a breeze compared.

Kubernetes seems cool :3

I finally got around to lidarr and fixed up a cleaned up a bunch of cron jobs i setup to properly log errors
