  • Personally I tend to be hesitant on relaxing the duel means of egres rule completely when i’ve seen buildings in Vancouver use two sets of stairs interwoven in the same stairwell to achieve the same effect with only a 30% or so increase in floor space. Even if it’s statistically not much help knowing there are two ways out of the building in an emergency does have an advantage, and i’m not convinced that it’s actually as much of a factor into the proliferation of double stacked corridors as them just being the cheapest way build.

    Otherwise i’m definitely a big fan of the suggestions, especially more interconnections between buildings.



  • Actual radioactivity matters quite a bit as to how safe it is, and that’s dependent quite a bit on the actual amount and thorium density of the specific item in question. From Tokaimura to a banana levels of radiation covers quite a large range, and I in good faith assumed that if someone was going out of their way to find and mention thorium on Unix socks of all places it was probably a pretty safe assumption that they know the basics and could check where on that spectrum the item falls, that it’s an excuse to play with a detector is most of the fun after all.







  • If it makes you feel any better, modern climate and economic studies have shown that even a full scale nuclear war involving every nuclear power at the height of the Cold War and when nuclear stockpiles were far larger than today we still wouldn’t have come very close to actually killing off all the humans on earth, with the vast majority of the casualties being owed to famine in regions that were/are heavily dependent on western fertilizer. Indeed entire nations in the southern hemisphere tend to get through such senecios without much of an direct effect from world war three.

    Mostly this change from earlier predictions came from being able rule out the theory of a nuclear winter as climate modeling became more accurate and we could be sure that the secondary fires from such a war could not carry ash into the upper atmosphere in significant quantities, which was practically shown when a climate change fueled wildfire in Australia got so large that it should have been able to carry the ash into the upper atmosphere under nuclear winter theory but none was observed, validating modern climate models.

    Also, dispite what some less scrupulous journalists trying to drum up clicks have posted on the Ukraine War, the Russian government itself hasn’t really made any major signaling moves with regards to bringing nukes into the conflict, and indeed has maintained and repeatedly reiterated Putin’s 2010s no first use policy when asked.

    Don’t get me wrong, this is not the result of some greater Russian morals or whatever, but just a consequence of the inherent risk that such posturing could lead to nuclear escalation and breaking the nuclear taboo or even just other nations actually believing they plan to, and such scenarios end very badly for Russia in general and Putin in particular.





  • Ment to hedge that with the qualifier often, as some manufacturers with little competition or reason to make cheap EVs do just use a cut down high end cobalt battery bank and pass the large additional cost onto the customer. It is a practice that is increasingly going away, and when it comes to things like moving everyone to EVs the general assumption is that regardless of what Amarican manufacturers want, most of them will go with the lower cost and longer lived chemistries over the premium density ones.


  • Neglecting that Cobalt isn’t even used in non-luxury EV’s in favor of cheaper chemistries like LFP or Sodium Ion, it’s worth noting that while so called ‘artisanal mining’ has been supplying much of the cobalt needed for over a half century now in oil processing, it’s being replaced by larger and cheaper industrial mines as demand for cobalt in electronics and premium EVs grew.

    Not that such industrial mining doesn’t come with local environmental costs, or that we shouldn’t work on better recycling capture for personal electronics, but sticking with oil sure hasn’t done anything to help the Congo so far.


  • Opinion pieces on the Internet and political saber rattling by low level politicians does not a nuclear policy make.

    States actually have quite a few different ways of signaling they are serious about potentially ending the world as we know it, and Russia is currently using none of them.

    As an example, the Russian state’s own published nuclear policy has remained unchanged for over a decade and still explicitly prohibits nuclear first use in cases like this. Currently high level Russian politicians including Putin continue to reference said defense policy in response to questions about the use of nuclear weapons in Ukraine. If they were seriously considering using said nuclear weapons in Ukraine, they would be unambiguously signaling through changing these documents and other such methods that other governments actually take seriously.

    More to the point, breaking the nuclear taboo would be massively harmful to both Russia and Putins own interests. It would at best result in a NATO backed no fly zone over Ukraine while China and Iran completely abandon them, and quite possibly result in a direct conventional or nuclear war with Nato. I simply don’t buy that they would do that with no warning or previous signaling simply because an artillery rocket was manufactured in a different country.


  • I mean, the government has mandated that all cars built since the 90s have to have a lot of computers and sensors for engine monitoring and emissions logging so that ship has long since sailed. Automatic braking is also credited with eliminating something like 1 in 5 fatalities in car accidents, so as long as we have any motorized vehicles around at all I don’t really have a problem with the government requiring manufacturers to spend the extra 20 dollars or so per vehicle it costs them to add a few ultrasonic sensors and a microcontroller it takes to slow the vehicle to the point where a driving into a pedestrian might just be survivable.
