  • Veritasium(?) has a video about jerry cans that boils down to “Surprise! The Germans over-engineered the crap out of these!” and how most modern ones aren’t as good because its significantly cheaper to make ones that just look similar.

    Still better than the plastic ones usually but you kind of have to hunt for the older style at this point to get the best of the best.


  • Which is the point. It’s not good, it meets the spec.

    Sometimes the spec means it’s overbuilt compared to a civilian version. A lot of the time someone not-the-government is willing to pay more for different features than the spec.

    An AR trigger going to a 19 year old just out of basic does not need to be match quality. Most of them suck as marksmen. Most of them will rarely shoot a rifle after basic because their MOS doesn’t require it, and they don’t need a good (read: more expensive) trigger to qualify for basic competence.





  • Thing is, in the movie he then reverses course to get the world spinning the right way again. He changes the rotation twice. I feel like the “visual representation of time travel” explanation is from people who haven’t watched the whole movie, just the clip.

    Maybe he overshot and went too far into the past and had to catch up, with raises the question why he didn’t stop everything bad in the movie by punching Lex Luthor right at the start…

    This video shows the whole sequence, he un-reverses the Earth’s spin at ~1:38.




  • They’ve done those studies and context switching has historically been where the most problems occur. Whether they’ve repeated them with modern electronic medical records and systems, I don’t know. I think most people agree there’s probably a better middle ground between 8 hr shifts (3 handoffs a day) and the standards set by a dude who liked to experiment with coke and meth.

    One of the big issues that I feel like doesn’t get touched on as much is longer shifts allow less doctors, which reinforces the artificially low doctor graduation rates. The national board in the US pegs the graduation at X thousand new doctors every year and that number is mostly tradition / vibes. No we don’t want to compromise on the ability of new doctors, but “gestures vaguely to US healthcare” good lord do we need more of them. Much the same could be said for nurses.

    And all of that circles back around to not wanting to dilute traditionally higher paying job markets with more practitioners because the for-profit system will try to wring out every cent they can.



  • The ISS has a lot of big solar panels. The other big panels they have are thermal radiators.

    They have to have quite large thermal radiators because it’s very inefficient. The ISS has people and a very small amount of computing power.

    Data centers generate several orders of magnitude more heat. You would need several orders of magnitude more thermal radiators than you would solar panels. The bigger you make the data center, which is important for density since you’re introducing a lot of lag due to the speed of light, the less room you have to put thermal radiators or solar panels.

    Then you need to work out how to get spare servers, and/or server parts up and down from the Data Center. All of these things are consumables, and all of them have significantly more wear and tear outside of the Earth’s atmosphere.

    It is possible. It is not efficient or sensible. It sounds cool, it doesn’t require buying land, and there aren’t currently international agreements about doing dumb stuff in space in the same way there are for doing dumb stuff in the ocean.


  • It’s a perennial thing with Jellyfin that it doesn’t have the app / remote access support Plex provides. By itself it’s a fully functional network media server, but by design it doesn’t have the ability to reverse tunnel and it doesn’t have the corporate infrastructure that gets it’s app onto devices.

    Yes you can set up wireguard / VPN access. Yes there are workarounds that can get Jellyfin streaming to most devices.

    None of that matters when trying to talk someone on the phone through connecting to your server through the internet.

    Plex is an account, it looks like a streaming service, it requires zero knowledge. I’m fairly certain some of my relatives have no idea it’s streaming from a server in my basement. Jellyfin they have to trust you enough to setup separate other apps / configuration and have the patience / attention span / ability to follow directions to do so.

    The bad ones I’ve been on are:

    • between old small town stations, so now it’s suburb to suburb and you can’t access anything in between so they’re useless for commuting. If the rail-to-trail revamp continued on it would go on through the former rail hub of the local large town, but that part hasn’t been built out yet, and may never be because at some point they’ll have to deal with crossing (hopefully over / under) highways and stroads that have been built up since.

    I have a proper bike trail in my home city that goes along a river and it’s amazing that it winds along for dozens of miles with stuff to look at and breezes. You’re not confined to a corridor with overgrowth on both sides causing stifling heat that’s trying to imitate a highway. It’s a pleasant commute if you happen to live along it and a relaxing recreational ride if you’re not.

    • long gradual grade. Coast one way, which is nice, Sisyphean bike ride with no rest for miles the other way.

    I might’ve come off harsh, I do generally like rails-to-trails. They’re better than nothing, and you’re right that having an ebike takes the arduousness out of it, but they’re very much a hand-me-down version of proper infrastructure. I would rather have the passenger light rail service.

    In the 1900s the small MS town I’m thinking of had a few hundred people and a rail station. You could pay the inflation adjusted ~$15 for all the transfers to go back and forth to the coast ~100 miles away. We didn’t discard passenger rail in the US because it wasn’t useful, but because it was hard to extract profit out of the public service.

    Lots of non-stop wars in Europe after WWII?

    The US was built on railroads, we just ripped up and paved over most of our passenger service in favor of cars. A lot of highways going through cities use the land the old main rail line used. Basically every city over a few 10s of thousands of people had some kind of light rail service. And then we decided that every public service had to also be independently profitable. So instead of pooling transportation costs across a population we each have to buy and operate personal vehicles for everything, not just leisure or convenience.

    They also feel like something designed by someone who hasn’t ridden a bike since they were 16.

    I get it. “Might was well” use land where the right-of-way is already clear, etc. But a miles of straightaways followed by gentle curves designed for a train don’t make for a very engaging bike ride. I’m sure this could exist, but I haven’t been on any that would actually be useful as bicycle infrastructure. They mostly go from nowhere to nowhere and there are few options to get on or off the ‘trail’.


  • The podcast Blank Check goes into it while talking about the movies, but that’s admittedly “long form”. Wikipedia has a good summary.

    In short, George Miller was an Australian ER doc horrified by what cars can do to people. So he got some funds together with some other doctor buddies and made Mad Max. He and Byron Kennedy wrote and filmed it because they couldn’t afford to have someone else do it. Mel Gibson was a local guy in film school. Most of the cast doubled as crew and basically made their costumes from scratch themselves. It became a bit of an indie darling in the US and Miller went back to Australia with more money and more expertise and made Road Warrior. More or less the same happened with Thunderdome. His work partner died, he made the Happy Feet and Babe movies, and he retained the entirety of the rights to Mad Max so he decided to make Fury Road and Furiosa a few decades later.


  • Bus lanes have higher throughput of commuters than car lanes.

    If a mayor created a private lane only they could use between their house and work, that would be a crazy abuse of power. Or say, put in stop signs / lights right at their subdivision so traffic was more convenient for them in particular.

    This mayor sped up the commute for thousands of people at a minimal impact to a significantly smaller number.
