  • Why it was made: “Commemorative.” They apparently stamped that decal on three different models of otherwise ordinary mainline matchbox cars. They paint matchbox cars at all to make them special; “I got a red one.” “I’ll trade you my blue corvette and my yellow and purple flames chevelle for your Halley’s comet firebird.”

    Who would buy it: Collectors, because “commemorative.” And apparently parents/loved ones of children, because it’s a toy car. I take it you had fun playing with it as a kid? If so, I’d say it did its job. Those little comet decals seem to have helped form strong memories of it.



  • Okay, so you know the trope in spy movies where the launch codes or the diamonds or whatever are at the end of a hallway full of lasers, and the protagonist has to do some cool flip moves (if male) or some slinky contortions (if female) to get around the lasers?

    I made that as an arcade game with an Arduino. Some red laser pointer diodes, some photosensors, a few lights, bells and whistles, a fog machine, a few big ol buttons, and you’ve got spy laser hallway. It had a separate “break as many lasers as you can” mode as well, played like a combination of DDR and whack-a-mole.

    The second coolest thing I ever programmed was probably the GPS MP3 player. A farmer wanted to add an automatic soundtrack to his Halloween hayride, like when the drove through the spooky graveyard it played ghost noises, it would play music for longer stretches on the road. I used a Raspberry Pi with a GPS HAT and wrote up a script in Python that would compare the actual position with a set of coordinates stored in a text file, and if one matched, it would play an associated mp3 file. The effect was kind of lost because the audio was coming from the vehicle itself, but it’s a hay ride, it’s supposed to be kind of lame. The bedsheet ghosts said woo as you drove past, I’m in the special effects industry, dad.



  • Windows 11’s TPM requirements.

    I recently built a brand new computer for my uncle. He was running a 3rd gen Core i7 machine running Windows 7. I get a call that it won’t boot. I do manage to get it booted, the SMART data shows the hard drive is on its last eyebrows, and anyway he’s running an OS that’s three generations out of date.

    I’m a big Linux user, I’ve got my aunt running Linux Mint. My uncle is such a dunce at computers I don’t think I can do that, because he lacks the vocabulary to tell me what he wants his computer to do. “I might use it for business.” In his line of work that could mean anything from going to quickbooks.com to needing some piece of Windows-only shitware. So “Get a .exe from somewhere” had to remain intact.

    For everything he actually does with that computer, that old 3rd gen i7 was fine. Replace the hard disk with a SATA SSD, maybe replace the weird 2-4-2-4 some but not all of it is dual channel 12GB of RAM with two 8 GB sticks of DDR3 and let it roll…except no currently supported version of WIndows runs on this computer.

    For a large number of people, computers became objectively fast enough in 2015. That’s about when SSDs became standard equipment, fixing any hardware reason for “damn this thing is slow” even out of midrange consumer hardware. Gamers, home labbers and AI startups need more power, the rest of the world doesn’t. And that was a problem for Microsoft.





  • I do shop at Best Buy, usually for computer parts and accessories. Because my local alternatives for computer hardware and peripherals, AV gear etc. are Wal-Mart and maybe our increasingly pathetic Staples. Or Amazon. Best Buy is literally the only place within 20 miles to buy a GPU in a brick and mortar store.

    I don’t watch TV ads though. Is this chick a spokesman?










  • You will sometimes hear older pilots refer to a magnetic compass as a “whiskey compass.” Magnetic compasses are usually filled with some liquid to dampen it so it’s ever possible to read; an air-filled compass never stops swinging back and forth. Water would be the obvious choice, but then you’ll have an algae filled compass.

    Legend has it that the US Navy in World War II used ethanol to fill the compasses. And then the planes would come back with empty compasses because the navy pilots drank it. So they switched to kerosene. And then the marines drank it.
