This little mechanical calculator is one of my favorite objects. It came to me with what turned out to be a fouled 10s pin retaining ring; it was a bear to take apart, ‘machine’ a new part, and reassemble. But it works! And I love it!

Time for an #introduction. I've been involved in #FOSS and #Linux since the late `90s. My career started as a sysadmin, pivoting to security. I'm the President of @purism and work on hardware and software to protect #privacy, #security and freedom.

I've written a number of books (kylerank.in/writing.html) and was a long-time columnist for Linux Journal magazine.

I have many hobbies including #weaving, refurbishing mechanical #calculators, #3dprinting, #brewing, and many other things.
