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.
