  • I’m sure I’ve read worse but one that stands out as making me question the time I put into reading it is Out of the Dark by David Weber. I go into it expecting a military sci fi, and for the vast majority of the book that’s what you get - aliens invade Earth and plucky humans resist etc etc. The aliens however have more reserves and air superiority so are slowly winning as the end of the book approaches, at which point you expect the main characters to pull a rabbit out of the hat and do something different. Except that’s not what happens.

    spoiler

    What actually happens is that Count Dracula appears out of (almost) nowhere and flies with a bunch of vampires up to the alien spaceships to kill the aliens, winning the battle for Earth.

    I was definitely not satisfied with this ending, even if there was some foreshadowing earlier in the book that made sense after knowing this was a possibility in this universe.




  • The thinking involved in driving a manual is very minimal once you get used to it, so I reckon any safety issues caused by that would be outweighed by a reduction in the unfortunately common situation of unintended acceleration crashes. You are lot less likely to drive through the nearest wall (or kids) if your instinctual reaction to moving when you should not be is to also go for the clutch and cut power instead of just pressing harder on the wrong pedal.


  • They have a clutch, but once you’re moving it is possible to shift a manual transmission without using the clutch. What you need to do is first take off the load currently passing through the box (if power is being transmitted either direction it holds the engagement dogs in place), so if accelerating you quickly let off the throttle and if decelerating you quickly tap the throttle. This lets you move into neutral, once in neutral you increase or decrease the engine revs to near (ideally exactly) what they would be in the gear you want to shift into at your current road speed, and holding those revs you can then shift smoothly into the new gear.

    It is not something I would recommend unless in a jam with synchromesh transmissions (e.g. regular cars, light trucks) as most people aren’t going to get it exactly right every time and will just burn out the synchros. If you’re unfamiliar with the term these are the parts of the transmission that let you shift from one gear to another in one motion without having to stop in neutral, let the clutch out, and increase/decrease the engine revs to suit your desired gear before clutching in and shifting into it.

    Clutchless shifting can and does work well in non-synchro transmissions (e.g. motorbikes, many heavy trucks) once you get the knack, as these transmissions are both more forgiving of not being exactly rev matched and will provide a strong auditory signal if you don’t get it close enough (i.e. you’ll know if you got it right or not so won’t half arse it). Many motorbikes now actually automate this process with devices known as quickshifters - named so because even when doing it by hand clutchless shifts on a bike are noticeably faster than using the clutch.





  • The ACT does get a bit cold in winter, but I feel like it’s closer to England than Finland (if England was drier and actually got hot in summer anyway). We are after all talking minimums of -5 or -6 for the coldest days in winter and snow normally only settling on the tops of the nearby mountain range (and temporarily at that).




  • It’d be interesting to see how much this changes if you were to restrict the training dataset to books written in the last twenty years, I suspect the model would be a lot less negative. Older books tend to include stuff which does not fit with modern ideals and it’d be a real struggle to avoid this if such texts are used for training.

    For example I was recently reading a couple of the sequels to The Thirty-Nine Steps (written during WW1) and they include multiple instances that really date them to an earlier era with the main character casually throwing out jarringly racist stuff about black South Africans, Germans, the Irish, and basically anyone else who wasn’t properly English. Train an AI on that and you’re introducing the chance for problematic output - and chances are most LLMs have been trained on this series since they’re now public domain and easily available.



  • A trebuchet primarily transforms downward motion (of the counterweight) into forward motion, so it would actually work - the trebuchet doesn’t push the ship back as much as it pushes its load forward. This is particularly so if your trebuchet has wheels and you have room on your ship to accommodate it rocking back and forth when firing.

    Edit: Thinking about it this technique would work even with something that does impart equal backwards force on the ship when firing a projectile, because there is considerably more force involved in winching the ship towards the anchor than what is involved in actually moving the anchor. You aren’t pulling against the inertia of a free floating anchor after all, you’re pulling against the ground the anchor has hooked into.


  • I never had a problem with walking around cows as a kid and I did it pretty often. Visitors would get spooked occasionally because cows love to follow you and see what you’re up to, but I never got chased or anything. That was beef cattle country though so these cows were mainly cows (female) and steers (castrated males). I’ve heard that some bulls could be territorial however so your mileage may vary if one is around - the couple I’ve walked around were fine but your chances of issues are higher with them.



  • All cars could last a lot longer if people kept maintaining them and - importantly - didn’t damage them. Electric cars are not going to be immune to this, I can’t see them lasting much longer on average than ICE cars.

    Keep in mind that even when you change out the engine for something with less parts the rest of the car still remains and contains things which will eventually cause issues. For example I bought a cheap van a few months ago and here’s some of the reasons it was cheap that are not ICE specific:

    • Steering wheel lock mechanism sticking
    • Air distribution flap cables kinked/binding so A/C only blew at feet
    • Central locking on side door sticking
    • Rear shocks leaking
    • Front strut mount bushings worn
    • Head unit not functioning

    Presumably the previous owner just didn’t want to spend the money on fixing these issues as they arose, and eventually it added up into a lot of potential expense (if you have to pay someone to fix it for you) and more reasons to sell the car. Such behaviour seems pretty common in my experience and I fully expect it to continue with EVs. It’ll be hard enough to get people to even maintain their brakes and change the motor coolant considering the natural reluctance of people to spend money on maintenance and this unfortunately prevalent idea that EVs don’t need it.

    Funnily enough the main ICE specific problem with that van was just as much an electrical issue as part of the petrol engine - an intermittent secondary air injection error code which ended up being down to a combination of a sticking valve and a fuse with a hairline crack causing an intermittent connection.
