Yeah I am not taking a position on how the market will do in the future. Just saying that active investing will underperform passive unless you are one of the few market participants who actually has alpha.

You may wish it were not so, you may find it inelegant and infuriating and unfair, but it is a fact that retail investors nearly all underperform the market over a long enough time horizon. Maybe you are built different but for most of us i

It does not, but it has a sane scheduling agreement with the railroad which the railroad actually respects. This is a common misconception because Brightline’s parent company Florida East Coast Industries shares heritage with Florida East C

Italy has not exactly privatized high speed rail. The public rail operator Trenitalia is by far the largest high speed rail operator in the country. And it’s great. What Italy has done is open the rails to access by private companies in

What about the principle of reciprocity? China doesn’t allow US social media companies to operate there—why should the US unilaterally allow Chinese social media companies to operate here with no reciprocity? Continuing to play cooperate ov

People with other options don’t take the train in (most of) the USA because the trains in (most of) the USA are bad. Of course the US is far larger than any single EU country, but the cities aren’t evenly distributed. There are many cluster

“Go to Vietnam” is maybe not the most practical suggestion for grabbing a cup of coffee, but that’s where I found the best Vietnamese coffee. As others have said, Vietnamese coffee was traditionally cheaper robusta beans, tended to be lower

In this case it’s not tokenization. I wrote the text preprocessing code that deals with spacing these numbers. This is good feedback. It’s optimized for US-style 10-digit phone numbers, and it should be more flexible than that. For example,

FWIW the issue is not mostly the builders—the issue is contracting practices and program management/oversight. California HSR hired (among other contractors) Dragados, which has a long history of building huge amounts of HSR in Spain a

Yes but as I understand it the very limited freight service on the peninsula just runs to a nearby UP yard. These are not big long-distance freight trains

by bryananderson 2y ago
Yes, unfortunately, but the freight traffic (which will needlessly stay diesel) is small, just a couple trains per day. It’s not the 1940s anymore when huge amounts of freight came ashore in San Francisco and propagated down the Southern Pa

This book is by Bent Flyvbjerg, the lead author of the paper being discussed here. He’s done a lot of great scholarship on how megaprojects go haywire, and uniqueness bias is definitely a big piece of it. You especially see this bias with N

I’m sorry to be negative because I agree with the general sentiment that society needs to stop treating “home value go up” as its primary retirement plan, and get rid of our allergy to social housing, but that first Guardian article about b

If you’re right, they did a stellar job of hiding it from the engineers working on the devices! Or maybe I’m one of the deep state cutouts. One never knows for sure.

This is hysterical. I never owned one until I worked on the product because I worried it was always recording/transmitting. Turns out it’s not. Promise. You don’t need a shadowy government cabal to explain Alexa persisting too long in

Sometime in the early 2000s they generated all the flight code for the James Webb Space Telescope from UML diagrams with Rational Rose. Over a decade later they were still trying to unfuck all of it.

Yeah, great point, especially since points are often the next bottleneck after station dwells (I’m thinking especially of BART’s Oakland Wye here). Close following really does not solve what matters for throughput.

As others have pointed out, most of this is a good idea and already exists in the form of moving-block communications-based train control which is used all over the world. The parts that don’t exist—traveling closer than the stopping distan

The way the Buy America rules work, there’s a certain percentage of work that has to be done in the US, and the rest can be done overseas. My understanding is that Stadler does most of the higher-skill work in Switzerland with its existing

My understanding (correct me if I’m wrong) is that the 2018 FRA reforms still set a higher crashworthiness standard for mainline stock than fully-separated metro (due to interactions with freight and road traffic), and that this is the case

by bryananderson 2y ago
The weird gauge is indeed weird, but is generally overstated as a problem for BART. There’s not much to be gained by changing it system-wide, and it would be at great cost. It’s sometimes claimed to be a driver of costlier rolling-stock acq

The Caltrain KISSes are not really off the shelf, in many ways, good and bad and ugly. The (arguably) good: 1) they have a boxier profile than the standard KISS, which some have complained about, but the reason the European version is less

This is a self-fulfilling prophecy, of course. High-speed passenger trains do very well all over the world. Coast-to-coast distances are too long for them, but cities in the US tend to be clustered at distances that are absolutely viable if
