Raspberry Pi Alternatives

The phenomenon behind the Raspberry Pi computer series has been pretty amazing. It's obvious why it has become so popular for Linux projects—it's a low-cost computer that's actually quite capable for the price, and the GPIO pins allow you to use it in a number of electronics projects such that it starts to cross over into Arduino territory in some cases. Its overall popularity has spawned many different add-ons and accessories, not to mention step-by-step guides on how to use the platform. I've personally written about Raspberry Pis often in this space, and in my own home, I use one to control a beer fermentation fridge, one as my media PC, one to control my 3D printer and one as a handheld gaming device.

Programming: Donald Knuth’s 80th Birthday and More

  • Octogenarianhood
    2018 began for me with an absolutely incredible 80th birthday celebration called Knuth80, held in the delightful city of Piteå in northern Sweden. It's impossible for me to thank adequately all of the wonderful people who contributed their time to making this event such a stunning success, certainly one of the greatest highlights of my life. Many of the happenings were also captured digitally in state-of-the-art audio and video, so that others will be able to share some of this joy. I'll link to that data when it becomes available.
  • Celebrating Donald Knuth’s 80th Birthday

    Don suggests that some of the participants who have a little free time might like to look at a few conjectures about set partitions and generating functions that he has put online at http://www-cs-faculty.stanford.edu/~knuth/caspagf.txt
