January 5, 2019 Update

The holidays left me stuffed, and so busy that work became an afterthought. My friend also had some medical issues and I ended up being a driver for most of the month. I swear, driving takes a lot out of me, physically and mentally. There are only a couple updates this month.

I’ll try to share one article I’ve read that’s tech/internet in each post.
