  • Cobalt 60 has a half life of 5.27 years.

    If the 7-1-63 is a date stamp of original manufacture, it’s gone through over 11 half-lives. There’s less than .05% of the original flavour.

    I don’t know about the decay products, but I’d wonder how far we are from legitimately edible.


  • If you’re thinking amplifier, just grab your favourite Japanese '70s hi-fi range and go from there. Can hardly go wrong.

    A half-scale Harman/Kardon 330c but with an OLED info display in the panel that held a tuning scale might kill it.

    The key is to use the right materials. They sold a modern CD-based stereo a few years ago that apes the look of a small Marantz 22xx, but being plastic garbage, sort of fails the mission. Conversely, Yamaha did some new silver-face amps that don’t look like dollar-store tat.


  • I sort of wonder if the next generation will still romanticize Japan in quite the same way. We’re past the peak trendy-products era of Weird Sony and the Toyota MR2, anime is no longer a secret exotic thing, and it feels like if you want “15 years ahead of us optimistic techno future”, you could easily slide in Chongqing or Seoul instead of Tokyo.



  • The UK issued silver dollars once. They were dated 1804 and considered “bank tokens” as they had less silver than their denomination required at the time. They basically stamped a new design on Spanish colonial 8-real coins and passed them as five shillings.

    The UK had a hard time with coin supply for most of the 1700s until 1816 when they finally downdized many coins.








  • Oil burning was common in some regions. The Southern Pacific had a lot of oil-fired engines. Their famous “cab-forward” steam engines could only make sense as oil burners without fundamental redesign.

    Part of it might be that the last holdouts for steam, who made the most technically advanced engines, were predominantly coal-carriers. They didn’t have the oil infrastructure, and didn’t want to burn relations eith their customers.



  • That’s what baffles me with the DOGE fracas. How long will solidarity hold when there are some very clear winners and losers within their own class?

    There are a lot of billionaires who have fat revenue streams coming out of the federal budget, and I don’t think they’re all eager to trigger some sort of Mad Max/Medieval social collapse just so they can be the Archduke of San Jose after America implodes. I doubt they all bought the Network State story.

    A fair number of them, expecting to live for more than 10 years and wanting to remain rich, probably invested aggressively into “skate where the puck is going” businesses that are now being slaughtered in the name of doubling down on fossil fuels and uncompetitive domestic manufacturers. Will Elon eat their losses? Of course, he’s committing financial seppuku too.
