I forget this every time: When you upgrade Fedora and a Dropbox popup asks you to download the daemon again. DON'T DO IT. Result will be Dropbox reindexing your entire Dropbox folder.
I'm doing the Fedora 29-30 upgrade (scorecard: 28-29 was fine, 27-28 not so much, all good from about 15 or 16 to 27)
I am loving the new terminal feature of Vim 8.1, especially in Windows 10 (hint: get it with :term)
