  • Big, big news today: The Raspberry Pi foundation is now shipping the rumored Raspberry Pi 2 board. (What this means in practical terms is that all your usual suppliers are sold out.) Will write more once I learm more, but geddaloadadis: Quad 900 MHz Cortex A7 CPU, plus a full gigabyte of RAM. And the sleeper, which is still tying my head in knots: The foundation has cut a deal with Microsoft to provide a version of Windows 10 that will run on the RPi2. The cost? Free. No more details than that right now, but I’ll be watching it closely. (Thanks to Bob Fegert for alerting me. Twitter has already earned its keep.)
  • Update: The new Windows 10 deal with the RPi community is part of Microsoft’s larger strategy on the Internet of Things, and will be available without charge through the Windows Developer Program for IoT.
  • Jim Strickland sends a link to Microsoft BASIC for 6502, in assembly. This is from 1978, and the oldest publicly available source code written by Bill Gates. The interpreter exists for the COSMAC 1802 as well, and I may still have it somewhere. It’s on paper tape, and I think in a metal 35mm film can. This was a great use for 35mm film cans, back when there were 35mm film cans, and paper tape to put in them.
  • Wired‘s vulcanologist Erik Klemetti has a fascinating article on how magma forms hexagonal pillars a la Devil’s Postpile and Giant’s Causeway in Northern Ireland. These figure in the yet-unbegun novella prequel to The Cunning Blood, so it was nice to get some science on them.
  • If you liked the Panjundrum (see my Odd Lots for January 29, 2015) you will love this thing, whatever they call it: It’s a Panjundrum that flies. (Thanks to Pete Albrecht for the link.)
  • UPDATE: One of my readers just wrote to tell me that it’s called a “girandola.”
  • Yes, this is short for an Odd Lots, but I wanted to get notice out on the RPi2 sooner than tomorrow or the next day.
