Installing nRF Connect SDK on macos

Conditions

Applicable to the nRF9160-DK and probably other platforms the SDK supports.
Correct as at 2021-04-07. Many fast moving parts so will likely age quickly.

Instructions

There does not seem to be any guidance available for installing QuestDB on FreeBSD. An enquiry on Slack created helpful suggestions, but nothing directly actionable.

For posteriority I decided to create my own installer. This seems to do the trick, and is modelling on the Homebrew configuration, for lack of a better idea.

As root:

pkg install bash
curl -LO https://github.com/questdb/questdb/releases/download/6.0.4/questdb-6.0.4-rt-freebsd-amd64.tar.gz
tar xvf questdb-6.0.4-rt-freebsd-amd64.tar.gz
cd questdb-6.0.4-rt-freebsd-amd64

Installing getmail on Synology Diskstation DS920+ with DSM 7

Did a survey of alternatives and am not convinced there's better out there. The built-in Synology stuff might be capable, but I don't think it's going to be as set-and-forget. So getmail it is.
Right, no getmail in the official Synology repositories, but it is in ipkg apparently. So just install that like last time right? Nope. It's opkg now, and the installer doesn't work on DSM 7!
- Wow, not getting far.
Okay, official instructions work just fine (the DS920+ is x86_64, according to uname -a), but need to wait for a reboot and I still have 5 hours of backup copying to go.
So in meantime, notice that the opkg getmail package seems to be v4 anyway, and v5 is available. So why not just install it manually?
