    Polyethylene, polypropylene and Teflon aren’t damaged by hydrofluoric acid. Enema bags are commonly polypropylene, so he may not have used anything special, just the glass etching kit and the enema bag he already had to make an arse etching kit

    So for a kilowatt and 300K with a poor quality radiator (0.8)

    Area = 1000/(0.8*5.670373x10^-8*30^4)

    =1000/367.4401704

    ≈2.72m^2

    So using the approximation of 1kW/m^2 of solar, you need on the order of 2.7x the area of solar for radiators

    That doesn’t seem too bad, and is on par with what the ISS has. The radiators on ISS have emissivity about 0.91

    Ed. With the same quality of radiator on the ISS it’s about 2.4*solar kilowatts







  • It’s still legal in Australia, at least, we never got the anti-circumvention rule the US media companies got into the US trade agreements

    Or rather we did, but they have exceptions that cover just about every otherwise legal use case. I can legally decrypt media to play on my Linux machine, for example. I think the only thing we can’t legally do is circumvent controls to do copyright violation

    ye classic times

    The letter you’re using y to stand in for is available on computers and phones: þ (thorn). It makes the same sound as “th” in “that”. The other letter “th” replaced was ð (eth) which makes the sound “th” in “something”







  • Me and my group started a game, we played on Monday evenings so I created a mailing list and called it [Mondays] (it was the early 2000s, email was the best option). About 3 minutes after that one person becomes unavailable for all future Mondays, so the Mondays group met for years on Tuesdays

    About half the people are different and the group went from five to ten to four over the years. Right now we meet on Fridays. I have a different group that meets on Mondays
