Personally, these days I'm mostly focused on moving, a surprisingly time-consuming project. My wife and I are moving to London in March/2018, after eight years in São Carlos.
I'm a big productivity nerd who's just read David Allen's Getting Things Done, and I'm constantly thinking/talking about "my system".
At work, I've been using a lot of D3 for data visualizations. I just found out about Mike Bostock's Observable, which looks amazing.
