Welcome to Five for Wednesday, our weekly round-up of tech-focused news.

      1. You should always, always, always be careful when using public wifi, but this article argues that for most of us, it’s ok to relax a bit. (The article contains some solid safety tips, so even if you’re in the “Free hotel wifi? No way!” camp, read on.)
      2. It’s hard to navigate the large number of Chromebook models and configurations. Here’s a guide to what you should be looking for on Black Friday if you’re in the market for a new machine.
      3. Microsoft is making a number of its products password-free. What’s the catch? You need to use a hardware key and some another form of authentication. Still, though, for those who don’t practice good password hygiene, this is pretty awesome.
      4. With large commercial spaces like shopping malls languishing, there’s no shortage of ideas for how to reuse all those square feet. There’s even a start-up that will put pre-fabricated housing inside old malls. (Reaction here in CRTLabs ranged from “cool!” to “ewww.”)
      5. We have no fifth item this week, other than to wish you and yours a Happy Thanksgiving and to thank you for reading and for your RTs.
