I'm a big fan of goofing around with a Raspberry Pi. At times I've used mine as a game emulator, media center, and caller ID server. Recently it has been sitting in a box, but now it's a DNS server that blocks ads on my home network thanks to Pi-hole. Pi-hole is software you install on a raspberry pi that filters the addresses you or your devices request through shared lists of known advertisers. It's simple to set up and it just works. I'm seeing 98% fewer ads across the web—no browser ad-blocker required. Once installed it has a nice web admin interface and it gives you statistics about which domains have been blocked. (8.7% of all my DNS queries have been blocked as I write this.) It was also easy to add my favorite ad-supported sites to a whitelist so they'll still get paid. It does bother me that this kind of tool leads to a nerds vs. everyone else experience (great interview, btw) but tracking, malware, and general browsing performance has gotten so bad due to ads that we need these tools. If you already have a tiny computer, Pi-hole plus an hour to set it up on a weekend will improve your web experience.
