Welcome to (almost) winter! I don’t know about where you are, but over here in the Bay Area we just started getting colder weather and rain. This last week and change I’ve started breaking out winter clothes, reviving winter foods, and all sorts of other fun stuff. Good to know that even with climate change, we still get some seasonality!

Whether it’s just getting cold where you are, or has been cold for a while, or you’re in the southern hemisphere and it’s starting to heat up, this week’s Friday Frontend has a bunch of articles you can curl up with in a corner and some hot tea. Enjoy!

Happy Friday!
