Pointing to this whenever the conservatives in Sweden say we need to raise prices and hire more ticket cops in order to increase ridership

Yeah researchers don't always agree on things. Definitely a question up his alley though, since I think he's done a video with a similar theme.

Actually, I just watched the new RMtransit video on YouTube, and he shows that the RER A in Paris runs double Deckers in tunnels through the center. It's more of a commuter train, but it's very close to a subway, and the first I've seen of urban commuter trains like that with double decker rolling stock.

Subway trains are designed to get people on and off the train as quickly as possible, with many doors and often platforms designed for quick transfers. Additionally, subways are designed for short rides, often with high stand/sit ratios.

Double decker trains are designed for long distance trips and to fit as many chairs on the train for a given train length, at the cost of number of doors and time loading/unloading passengers.

worth asking RMtransit on Mastodon, though.

Don't conservatives resent democrats either way? They have so much of an advantage through the EC that the democrats have to go liberal+progressive big tent, but still they complain/fear the amount of non-whites and atheists in big cities.

Also don't black americans + lgbt also resent their underrepresentation? Why should rural white populations get to speak over them? Just because historically that's been the case and we don't want to hurt their feelings?

"Online political pundit calls politician and discusses labor politics and economic policy, presumably offering investment in return for subsidies or other kickbacks"

"not about politics btw"

Like cool that Musk didn't start with the conspiracy theories or go full antisemite again, but I really hope that's not what people consider politics these days.

The eye has since expanded and the winds have spread out more, I believe.

SSDs last longer than hard drives in most situations.

What do you mean poor speeds under load?

64TB ssds are fairly common in the enterprise market now, I don't think they were 6 years ago. It's possible we'll see 128TB SSDs become fairly common on servers in a few years.

It's looking like 2029 will be the turning point. Right now, we are on the verge of having 16tb m.2s on the market, and by 2029 SSDs will be around $10-15/TB like HDDs are now.

In 2029, if semiconductor trends continue, it is likely that we will have 16TB SSDs for ~$200 and 32TB SSDs for ~$500; Cheaper than the $320 we're paying for 20TB HDDs right now.

The HDD industry doesn't seem like it will improve at the same rate. It is likely that the SSD market will have better $/TB than the HDD market in 2029, unless hard drives make some massive breakthrough before then. The survival of the HDD industry past the next 5 years is basically riding on Seagate's ability to successfully release HAMR technology.
