The sailing model is intuitive and easy to get to grips with, and it behaves much like a real boat. You can even get it to rock by moving from one side to the other.
Best of all it's totally seamless being on and off the boat, no invisible walls (you can, and will, fall off the fucking thing in the middle of the night)
Most of my time got eaten up by fucking about with Kernel compilation, which I'm well out of practice with and I don't miss at all, plus KISS doctrine means they steer you away from Initramfs so you have to get everything working in-kernel which isn't as easy as one might think.
Researchers that have their own VMs are very keen on curl | bashing their way through any how-to guide, adding all sorts of cruft that then completely toilets the machine a couple of months down the line.
I've started noticing a pattern in 3rd party repos on RHEL/Centos outside of the well-mainiained EPEL: They break, often pretty quickly. PostGIS has been a shitshow on every server it's been on, as has Dell's linux toolset. They keep fucking breaking yum/dnf and it's just a complete mess to sort out.
I appreciated this guy's film of his single-handed voyage. There's a lovely bit where he chats with a cruise ship, both parties must appreciate alleviating the loneliness.

I also got a $5000 bill from a lab because my oncologist had to send biopsy items to them to be identified; I had no say in the matter. The lab were really good about this though, and sorted it out for me.
Likewise when I was treated for what was a pretty high-risk cancer, I had to wait for approval several times for certain things. So some anonymous pen-pusher has more power than an MD. It's complete shite.
