  • Why is a electric motor overheating dangerous? Surely any electric car is going to have a system to throttle itself if overheating is an issue, and it will need that with or without gears.

    The fastest accelerating electric cars are single speed, presumably because it’s not worth changing gear when you only have 2 seconds.

    I can see why it might be useful in specific product categories, but when it’s not helpful for price or performance or reliability, that’s going to continue to be niche. The real problem electric cars need to solve right now is cost and a gearbox isn’t helping with that.



  • Electric motors have so much torque even at low revs that a gearbox is unnecessary for most people. If you can get enough torque for a fast start in 5th, there’s no reason for the gearbox, you might as well save the extra complexity and keep the car permanently in 5th.

    Combustion cars have gearboxes because they only work well at a narrow range of revs. Bicycles have more gears than cars because humans have an even narrower range of revs where they work best at.



  • I think it’s useful terminology, but only very generally and in hindsight. Web 1 is a pretty clear era in the 90s and early 2000s, characterized by simple static blogs and personal websites, and email. Everyone knew this would be big, but nobody figured out how, that was the dotcom bubble. Web 2 began with the rise of big tech companies like Google and Facebook in the late 2000s, it has been characterized by social media apps, centralized platforms hosting user created content, funded by targeted advertising and data mining. Web apps became possible and smartphones took over. Every product became a subscription service.

    I think we’re at the start of web 3, but it’s hard to say what that is yet. The big tech companies are crumbling and there’s increasing unrest at the old system of web 2. Fed up users are turning to platforms like this. There’s a lot of demand for crypto nonsense like NFTs. AI is changing the way we do everything.

    I hope that web 3 is the age of decentralization because that would be awesome, but it’s impossible to predict the future.





  • I gave it another shot having not attempted for a few years, I was looking for the most complete, stable, non-free, offline, x64 image for a USB flash drive. I failed very quickly because I didn’t know whether I needed a CD or DVD image. A few minutes of clicking through random and irrelevant “FAQs” and I finally found an answer I understood but only through experience, CD images are smaller than 700mb and my flash drive is large, so I wanted a DVD image. Back to the top, and I found the image I needed.

    So it took a few minutes, and I’ve done this several times before. A new user would have absolutely no clue.
