Even though most traditional December activities are a bit impractical this year, Eric Wastl returns with his annual Advent of Code. Every day from December first until Christmas Day you get a small puzzle that you can solve by writing small programs or by being very good at solving jigsaw puzzles. If you want to learn a new programming language or just get better at the ones you know, I highly recommend trying it out.| bertptrs.nl
About 8 years ago, I turned off and carted away the server running boinkmarks (aka autobench), the benchmarking and performance tracker for SBCL. It seems like its last planet.sbcl.org entry was around 2009-04-11. At the time, it had run benchmarks on every revision1 of SBCL since 2004 - I’d been running it for 8 years, as long as I now have not run it. Time for a retrospective!| boinkor.net
