I got a Yubikey 4 half a year ago (during Red Hat Summit 2016), but until now I didn’t do much with it. Time to change that ;)
I’ve been a longtime user of Crashplan, an easy-to-use cloud backup solution. It works well, and it used to work also on nearly any platform that had a java run-time and some add-on opensource libraries. I’ve used it for some time on my raspberry pi to automatically backup my data to the cloud. (Crashplan on ARM (the architecture of the raspberry pi) is an unsupported configuration though).
I finally decided to retire my custom-written CMS (wrote it back in 2003, when I had more free time), which - while obviously fantastic, super advanced, and capable of making coffee for you - had some drawbacks. Mostly being that it was a pain to use and update content with.
An update on the “My history in gadgets”, the 2014 and the 2015 update, now the 2016 update. Who would have guessed!
Something like this, perhaps...
