For all that I did not care for them originally this is probably something full-height platform screen doors help with, assuming the trains themselves are also filtered that would keep the pollutants clear of drivers and users, although it does not exactly resolve the question of managing their presence in the tunnels themselves (and track / tunnel maintenance personnel should probably already be wearing respirators if not full breathing apparatus), and I could see things get pretty dire in case of breakdowns.

Regen braking means significantly less brake dust, especially at city speeds and with blended braking.

> Although…rail might solve those?

Trains still have brakes. Some can regen brake but because they usually don’t have batteries they need the rail or overhead gantry to support inputs.

But on a passenger-mile basis, I expect an electric train produces essentially no particulates compared to a car, even a light rail on tyres. I do not however have numbers.

It was never OS-X, it was OS X, and originally Mac OS X, as in the one after Mac OS 9. The Mac prefix was dropped with Lion (10.7). The Mac OS lingo having itself been introduced with 7.6, before that the OS core was called System.

Mainland Europe has “crazy environmental and labour regulations” and manages to build cheaper and faster. So no, your pet hate is not the reason.

Wrapping the rule in a feature query seems a lot cleaner and more reliable.

Firecracker is designed to start a VM in under 125ms and 5MB. Netbsd advertises that you can direct-boot a MICROVM kernel configuration in under 10ms.

An other commenter pointed me towards the link in the first footnote. May I suggest linking most of the opening sentence, from "a post" to "curlese"? That would make it very clear where said previous post is.

Also maybe cross-link the italian and contributed english versions of the original post in case someone else finds the former and can't read italian, the contributed translation is definitely quite a bit better than Apple's automated translation at the very least.

Also is there an approved English version of it, or the same information by someone else?

edit: as pointed out there is one (to an english translation) in the first footnote

They don't need to, and the might not even do that, but the boosters and the clipfarms are very much in on it. You don't see that "engagement" for continuous sidewalks and raised crosswalks despite how amazing they are.

And they're also very convenient as a way to avoid infrastructural improvements, you can point to disability dongles as a reason not to invest in it, that way you're conveniently not bearing the cost.

> And as the post mentions, such infrastructure is useful for anyone with luggage, a stroller, or a hand truck.

The problem is that's at best a post-hoc realisation, when that argument is made upfront it's pretty much always dismissed out of hand (very much blub adjacent), you can see it in pretty much every discussion about better walk/bike infrastructure.

That was the entire point of the tech. If Google had wanted they could have upranked simple and lightweight websites but they didn’t do that (at least not until whoever had used amp for their promo package left and the project was killed).
