Recursive mutexes are a hack

Recursive mutexes are a hack. There's nothing wrong with using them, but they're a crutch. Got a broken leg or library? Fine, use the crutch. But at least be aware that you're using a crutch, and why; and once in a while check out the leg (or library) to be sure you still need the crutch. And if it's not healing up, go see a doctor, because that's just not OK. When you have no choice, there's no shame in using a crutch... but you can't run very well on a crutch, and you'll also be slowing down > anyone who depends on you.

Server image

I use Ubuntu 16.04/Ubuntu Xenial.

Setup server

Add a new user who isn't root, but who can sudo:

1. Update all the things: apt-get update && apt-get dist-upgrade && apt-get autoremove
2. Reboot, just in case: shutdown -r now
