Update 31August2019: Ugh. It all gets rather more complicated than I like by the time you get WiFi and the Tor hidden service running. I was thinking of creating an SD card image, but then I’d have to maintain it for each new release of Raspbian. Josh suggested that, instead, I create a bash script to do the whole install to a vanilla Raspbian. If you’ve tried creating this and got lost, stay tuned and I’ll do the installer as time allows. Email me if you want to encourage me to do it sooner.

I just renewed my membership to TidBITS. If you’ve never heard of TidBITS, you should check them out. They have been publishing continuously online for 28 years, and their content is second to none. They also host an amazing online discussion list, TidBITS-Talk. The site’s content is focused on Apple news and technology, but the quality of the journalism is so high and the coverage is broad enough that there is likely something there for everyone.
Membership is completely optional, so check it out. It is not hyperbole to say that TidBITS has improved the quality of my life every week for the past quarter century.

Note: be sure to read to the end before you start implementing any of the scripts. They're currently out of date and no longer work.
Our little family has undergone something of a revolution of late: it’s called Minecraft. Matthew started playing it, and watching YouTube videos about it, a few months ago. I’ve never been a gamer, despite rumors to the contrary, but Minecraft captured my attention. It’s a sandbox game, where you gather materials and use them to craft new materials and make tools and build structures and create an entire world. It’s addictive and amazing, and the story behind it is a classic indie-game David vs. entertainment industry Goliath tale.

I run an asterisk PBX, largely to handle the complex telephony needs of Sacramento Medical Oasis, Inc. If you don’t know what an asterisk PBX is, you can stop reading now and you won’t miss anything. I promise.
