  • I asked gpt for code to aim a heliostat

    It needed a module to get the sun’s position, it used sun::alt:: azimuth which doesn’t exist rather than Astro::Coord::ECI::Sun

    It needed a module to calculate mirror angle between the Sun’s altitude and azimuth and the target altitude and azimuth. It left that commented out rather than selecting the altitude halfway between Sun and target and azimuth between Sun and azimuth

    It turns out there’s precious little on the internet on how to aim a mirror, partly because it’s not popular, partly because it’s dead simple





    • I prefer to wear socks
    • I used to be fat, so skin tight shirts don’t look good on me
    • I like button up shirts
    • In cool weather when I wear long trousers, I prefer not to have my ankles frozen
    • In hot weather I’m keeping as much of my legs bare as available men’s bottom wear allows

    All in all I don’t like that style. I knew a boy who liked that style as a youth, he was a arsehole




  • On the reasonable side of the balance sheet, Australia is moving so fast installing big batteries that CATL has named one of their products after the Australian company they’re supplying batteries to

    Also we just had a study published and publicised for efficient pumped hydro locations near each population centre (though one state missed it and approved development of a pair of pumped hydro reservoirs in a location the study ranked poorly, leading to further advertising of the study and how its chosen site near the approved one would have been a tenth the cost)

    Rooftop solar is so popular that grid demand in one of our two large cities was at an all time low recently

    All in all it’s pretty promising here

    Though just like America, a change in the party in charge can wreck a lot of the progress



  • I have found a supplier of 5kg lots of beef suet pretty cheap, and will be having a go at making pemmican in the next few weeks, which should make ~3.8kg of tallow, which (along with 12.65kg of fresh beef) should make 7.6kg of pemmican – enough for 10 to 20 days (all numbers are fuzzy until the tallow is made and measured)

    I have made tallow before so I know that part of the process well

    Do you happen to know a good lean cut to use?



  • Now I just wish someone would teach how to respond to common “can’t do it because…” comments

    I have a friend in his late 50s, type 2 diabetes, carrying maybe an excess of 40kg fat, who can’t do carnivore “because there’s too little variety”

    I say “low carb will give you most of the same benefits”

    Him: “not enough variety”

    Me: “why not try for a month or so and see what it does to your glucose monitor?”

    Him: changes subject

    Meanwhile a 35yo relative is “too addicted to sugar” and unwilling to hear about how to beat an addiction (though they agree that sugar would be easier to quit than cigarettes and many have quit smokes)
