    Can a business transact with an animal?

    If a crow puts a toonie in a vending machine, and manages to buy chips does it legally own the chips? Or can an agent of the business that runs the vending machine confiscate them and keep the money?

    Okay, I think $80 Canadian for a case, psu, mobo, cpu, & ram is sounding pretty reasonable. I just don’t know of its enough processing power for the video stuff. But I guess if not I can upgrade the mobo/cpu or add a graphics card.

    Thanks, that channel looks great.

    Re offsite backup: Yes I don’t have so many family photos that it will be difficult/ expensive to store online. But I need to get them together first.







  • How much extra force does a vacuum tunnel have to withstand to avoid collapse, compared to a regular tunnel?

    Dirt weighs ~1.5 tons per cubic meter. So one meter of soil depth is 15,000 N/m2 (1500kg * 9.8 m/s2) so 15 kpa/m (which is 2 PSI per yard of depth).

    Vacuum can’t provide more force than atmospheric pressure. Atmospheric pressure is 100kPa or 15 PSI. Adding vacuum load adds the equivalent crushing force as digging a tunnel 6.5-7m deeper (7.5 yards). I don’t know why this is totally insurmountable. Take a thick walled concrete tube, coat the outside with some sort rubber, bury the tube and pump out the air.

    Yes you need to seal between sections, and keep sections aligned. I’m not a civil engineer or whatever but it doesn’t seem crazy hard. It just seems like… not important. It seems a lot more expensive, and less beneficial than just making a good surface transit network. Who cares if it would let me get from Vancouver to Seattle in… half an hour? If it’s already taking me an hour to get to the station and find parking, and get through ticketing/security/ customs.

    It’s only 2 hours from Surrey to Everett in a car (ignoring customs). Maybe we should just like have a bus?







  • The US (and Canada, where I live) has an extradition treaty with Romania.

    The US treaty does mention that

    …neither Party shall refuse extradition based on the citizenship of the person sought.

    But I haven’t read it in detail so that may or may not be relevant (the past I quoted is referring to a particular part of the treaty).

    My understand is that typically the threshold for extradition is mutual criminality which I suppose is my answer to how US law applies itself outside US territories (because leaking state secrets is a crime in most countries). So I withdraw my inquiry.

    If Romania declared Borat a state secret pirates could perhaps be extradited.

    But also note that I don’t think Assange can be charged with treason, because he isn’t American.




  • Yeah the inconsistencies are interesting.

    Is it because of the “than”? Do we just not like saying “fewer than”? Because it wouldn’t offend my ear to hear “we need less than 5 chairs”, but “we need less chairs” is outrageous to me, (for less than however many chairs it takes for them to become dequantized) [I did it again there, did you notice?]

    Or maybe it’s to do with the minutes being a quantization of something continuous, whereas usually we deal with the transition the other way.

    “couches vs. furniture” couches are discrete, furniture is discrete things as a collective.

    “time vs minutes” time is continuous, minutes are a quantization of it. That is a difference compared to couches/ furniture. How do we talk about other quantizations of continuous?

    Distance: how far is it? Less than 5 miles. Maybe it’s an acknowledgement of the fact that we talk about miles but inherently understand that distance isn’t countable.

    Oops that used “than” again. Uhhh… “the battery in my electric car is degraded so I get 10 less miles per charge”. Hmm I’m not sure if that sounds right…
