The British explorer gene is still alive. In 1998, Karl Bushby set out to walk from the southern tip of Chile all the way back home to England. He thought it might take 12 years. It’s been 27. Since then, he’s crossed jungles, deserts, frozen seas, and some of the harshest places on Earth. He made it through the Darién Gap, crossed shifting ice in the Bering Strait, dealt with arrests and visa issues, and somehow just kept going. Now, after more than two decades on the road, he’s finally closing in on the finish, with England expected in 2026.

Take it from me, as someone who did COPIOUS amounts of Ketamine in my 20s, that is not all he is on.

The hardware in old Chinese cloud accelerator cards never fails to impress me. If you go on Chinese ebay (idlefish) you can get a Xilinix UltraScale FPGA for ~$50 USD. For perspective, the same raw chip is currently ~$2,100 on Mouser.

Is your software is running in a simulation? Trust me, sometimes you really, really care. There used to be a really simple, single-instruction trick in x86 assembly, affectionally known as “the Red Pill”. SIDT is an (unprivileged!) instruction that tells you where the Interrupt Descriptor Table lives in memory. On bare metal, the IDT sits pretty low. Early VMware placed its virtualized IDT in a very high address, to avoid the guest colliding with the host. Very easy check, IDT high = you’re in a simulation! Most consider SIDT to be an actual flaw of x86 architecture design. In computer science terms, it fails the Popek-Goldberg test. Intel engineers didn’t anticipate the security risk in the 80s. The single instruction redpill doesn’t work anymore, hypervisors are way better now. We’ve got extra ring levels, multiple cores, KASLR, you can also trap + lie. But it was fun while it lasted! Of course, modern “red pills” are very advanced; anyone who’s worked in reverse engineering, malware, anti-cheat, DRM, (maybe timekeeping too?) is intimately familiar with VM detection. I’m curious if there are any other fields that very strictly check for emulation.

Magic Carpet 2 by Bullfrog, from 1995. One reason I liked Bullfrog (and miss studios like them) was their willingness to take risks and try new concepts. Look at their track record: Populous, Dungeon Keeper, Theme Park, Syndicate - none were mainstream games. They dared to be different, and that’s why we still remember them today. Magic Carpet 2 fit right into that mold: it was a wonderfully weird mix of flight sim/shooter, exploration and strategy. Thank you, Bullfrog, for being epic during the golden era of gaming. You are missed!

@ankkala Axially aligned KD trees are generally a better choice for spatial partitioning today than arbitrary plane BSP trees. Quake was about the end of the times when rendering geometry usefully coincided with partitioning geometry.

And there goes the MS Unsinkable... Apparently, she was in an appalling condition. Pitiful. Most disappointing. Ports of Call (1989)

@TodayinHistory Nobody talks about Veteran Pilot Mike Mueller who stole an A-10 for a rampage, resulting in the destruction of the vehicle, the very same day.
