High-throughput transit isn't there to be better in 1:1 comparison with one person's car trip, but to make better cities possible.

If you only imagine this as a static scenario where everything is the same except you swap car for a train, of course car looks better.

The problem is you're not in a single-player game full of NPCs. When everyone else also chooses the car, you physically run out of space for everyone's cars, and end up with a city full of asphalt and large roads that are dangerous/inconvenient to cross and unpleasant to be around.

Car infrastructure takes a lot of space. When it can be reduced, it allows building amenities closer together, so you can have multiple useful destinations within walking distances not much worse than crossing a Walmart parking lot, and you get an environment that's nicer than a parking lot.

Being crammed in a train that moves 3 million people a day is the price to pay for not having a sea of asphalt for ~3 million cars.

And all the associated pollution, overheating and flooding issues that go along with it


I didn't think LLM's sycophancy would work on me.

And yet, I've realized that a few research and brainstorming sessions with LLMs I thought were really good and insightful were just the LLM playing "yes and" improv with me, and reinforcing my beliefs, regardless whether I was right or wrong.


Two simple words

“Devils advocate”

And you get much better responses


There's hardly any Rust in there. It's shelling out to the git command. This could have been a couple lines of bash.

Actually doing this in Rust with lower-level libraries like gix would have been interesting.


I've found that using Git libraries directly is usually slow and less ergonomic. I've got another tool (written in Go) here: https://github.com/zikani03/git-monorepo which uses a Git library and is a bit slow.

But I'm willing to take up that challenge and test out gix, I've regained my interest in Rust so the timing is good :)


Value of TSLA has been disconnected from the actual car business for a while, and instead vaguely betting on Musk figuring out something with robots, taxis, or AI or whatever.

Now I wonder if it's tied to any future of the company at all. It seems to be a Musk stock: if you want Musk have more power to do whatever he's doing, pump TSLA.


I don't think you'll find anything much better than basis universal, assuming you want textures compressed on the GPU and the simplicity of shipping one file that decodes quickly enough. I've followed development of the encoder, and its authors know what they're doing.

You might beat basisu if you encode for one texture format at a time, and use perceptual RDO for albedo textures.

Another alternative would be to use JPEG XL for distribution and transcode to GPU texture formats on install, but you'd have to ship a decent GPU texture compressor (fast ones leave quality on the table, and it's really hard to make a good one that isn't exponentially slower).


Breakthrough in image generation speed literally came from applying better differential equations for diffusion taken from statistical mechanics physics papers:

EV motors typically outlive the rest of the car. Leaf is old enough that there's a whole cottage industry of battery repairs, replacements, and repurposing them for solar energy storage.

I assume you mean the batteries? What do people use the motors for?

I've meant you don't need to worry about motors failing in old EVs, unlike engines that are the primarily concern in old ICE cars.

Apart from battery degradation, the other thing that may be the final nail in the coffin for an old EV (other than Leaf) is failure of HVAC. Temperature management is important for keeping batteries healthy when fast charging, and to prevent motors from overheating when you send them a quarter of a megawatt of power.

And the rest of the problems is the same like in any other car of the same era.


The absolutely worst efficiency I've experienced was 2.7km/kWh at 120km/h in DS3 e-tense. That was a v1 Stellantis drivetrain, without a heat pump. Peugeot e208, Corsa-e, etc. are the same thing. Stellantis sucks at EVs, especially their first gen, so that's probably really the worst case scenario (apart from EV's nemesis: towing non-aerodynamic trailers at high speeds).

So if you take an EV's battery size in kWh and multiply it by 2.7, that's the worst range you will get in km.

In normal weather EVs get 5-7km per kWh.


It depends where your contributors are coming from. For example for Rust, the crates index is the discovery mechanism. Contributors will come to your repo by whatever link you put in your package's metadata. I've split my Rust packages between GitHub and GitLab and don't see a difference in participation.

You won't reach the limits of weight and handling of EVs when driving on public roads in ways that don't risk jail time.

Most people don't take their old Toyota to a race track, so they don't need their Leaf to beat a Lambo either.

The instant 0-30mph is the biggest advantage in day to day driving.
