Metric isn't magic but as an engineer who's had to use both systems for my whole career[^1] I despise the imperial system. Factors of 3, 8, 12, 640, 5280! Fractions used in carpentry. Just centering a picture on a wall is annoying.
I will agree that a temperature interface in °C should read in increments of 0.5 in order to have roughly the same resolution as when in °C (and many don't, but that's poor UX). I don't care about 0-100 being roughly aligned to human environments - 0-100 being aligned to freezing/boiling of water is just as good a reference.
[1] of the many things that Reagan should be despised for, cancelling metrication is probably not in the top 5, maybe not top 10. I still despise him for it.
What ticking time bombs? Please be specific. I'm an EV owner who has done no maintenance in 26k miles. I want to know which system, if I don't do maintenance, will create some hidden wear which will progress silently until too late.
Shocks, springs, tie rods, steering systems, motor mounts and any other rubber parts, cooling systems, braking system, wheel and possibly motor bearings.
Nothing special for being a car, but an ICE and transmission weren't the only things on cars that move and wear.
There's no maintenance to shocks, springs, tie rods, motor mounts, or wheel bearings. Every one of those announces their failure with clicks or clunks or bouncy ride. I'm not sure when chassis lubrication went away as a maintenance activity but I'm guessing around the '80s. I can remember using a grease gun on my parents' cars but none I owned. EVs obviously eliminate all the engine internals, so no spark plug replacements, no ignition modules, no accessory belt, no timing chain or belt, no engine air filter, no oil filter, no manifolds, catalytic converters or mufflers.
Brakes need to be inspected but my last ICE vehicle went about 90k miles between needing pads. My EV has sealed drums in back (a choice VW made to reduce friction when brakes aren't in use and I think trying to slow corrosion of the components) and conventional large discs in front. If we have issues with the front brakes it will be due to corrosion as I don't expect to put enough wear on them to ever wear through the pads. In normal driving the brakes are only applied at full stops.
I don't expect EVs to have motor mounts like an ICE vehicle, as the motor is a few orders of magnitude smoother (commutation ripple vs cylinder firings) and shouldn't need fluid-filled rubber isolation mounts.
If I think of what I've had to replace on my cars over the years, half-shafts and CV joints and wheel bearings might now be the least reliable mechanical things on the car, plus the oddball failures, like a clock spring in the steering wheel or a window motor.
So I still have to keep tires inflated, rotated and balanced, keep good wipers installed, change the cabin air filter occasionally, and listen to the rest.
My source for my opinion is having done the vast majority of the maintenance and repair of our cars over roughly 4 decades and more than a million miles.
20+ years of preparation does a pretty good job though.
I often wonder about the world we would live in if the Brooks Brothers Riot had not succeeded. That appears to have been the turning point for the fall of the USA, and even more sadly, humanity.
Lul. No. Everytime one of these "look how amazing Julia pots comes up", myself and many others do what we can to protect other people from wasting their time or their money from using it due to our personal experiences with it professionally or as hobbyists.
Can you give an example of general purpose use? It's not great if you want to make a standalone program and distribute it to other users. It's awesome if you are doing exploratory stuff, quickly exploring different ideas or algorithms. The ecosystem has a lot of high quality stuff but where it lacks you can of course call out to python or R or other languages.
They are green too, which means they were just made today. That's a pretty nice HN feature! It shows that there's literally 5 adversarial green sock puppet accounts that were made just to comment in this thread, so almost certainly one person with a grudge who is afraid to make a non-anonymous argument on the merits.
