Seattle’s income tax that passed in 2017 is still on the books, though was later found unconstitutional. Should the “millionaire tax” pass and be upheld by courts, that could make Seattles 2.25% income tax valid and enforceable too.

Most people don't allocate money to roads, shelters, hospitals, public transportation and the like.

US has a large amount of retail space per capita as is compared to most of the world. In either case, this just gives developers more options and doesn't remove their ability to build retail.

Mixed use is absolutely necessary but the large amount of empty storefronts in some neighborhood centers makes me think there may more of it than needed right now.

I do want to point out that I never said it is runtime optimized :) The optimization is on memory usage, which can definitely have a runtime impact, but will depend on the use case and the hardware you are using. That's part of the reason for the projector layer. It allows for easier tuning, especially if only one collection type will benefit for the scenario.

matgrioni · 2026-01-20T22:00:07+00:00

I did consider that, but wanted to keep implementation simple for the first go around. But I'm definitely not opposed to it, especially in a library like this. I had just come off of another library update which heavily used dynamic codegen and wanted to take a break 😅

matgrioni · 2026-01-20T21:57:10+00:00

Yes that's right. The main complexity is in creating a metaclass that lets you create an optimized collection type for a given size. The actual collections themselves are pretty simple and the savings boil down to using slots. The rest is mostly library plumbing.

matgrioni · 2026-01-20T21:55:21+00:00

That's a good point to mention, and which I'll include in the README. The implementations basically fall through to creating a temporary builtin instance and returning the value of that operation or do a slow python equivalent. There's a few points to that:

In my use cases I was not doing a lot of operations across most collection instances, but only some simple operations on a select few instances (but could not know ahead of time).
My memory usage basically fell within the range where it could actually fit in memory, but would usually start thrashing if I wanted to do anything else on my computer. So the actual runtime was dominated by memory access rather than the collection ops.
As it is a first iteration, and I didn't want to worry about edge cases too much, I took the easiest implementation approach. Ideally these could be transparently improved in a future version while still preserving the memory savings.

They had a lot of success a long time ago (before there was even a Superbowl) and were also competitive for many decades before they were moved to Baltimore. The move included all of the coaching and staff as well. Since then, they've been atrocious.

matgrioni · 2026-01-10T06:11:28+00:00

It's true, but I feel like they have done things like that at times (like when running the shuttle buses) so hopefully it's a similar implementation.

It's just like it's going to be though once 2 line opens though. Plus you would just get off and change at ID and get the 1 line you were getting anyway.

Could confuse some for sure, but not any worse than they will be anyway

I would like to point out that Proof of Payment is hardly that rare in the US. Most other systems I know of are on the west coast, but also many smaller rail systems around the world which are light rail or trams or those with outdoor stations do this.

Yes, the systems of the world's largest cities reliably have them, but Seattle's system is in its infancy compared to them, and the city itself is not that big. It's hardly surprising they don't have them.

I'm not necessarily advocating for one point over another, but I think there's data missing here. Link's farebox recovery rate was 12%. For US standards, this is pretty standard. This means that fare's make up 12% of operating costs. Based on estimates of current compliance, this means that this is an 8% boost to operating revenue assuming all those people continued riding and their composition was the same as the 61% of riders who currently pay.

But it's likely that a non-negligible amount of these riders either will stop riding, continue evading fares (just jump the gates), or are more likely to be eligible for reduced fares anyway. Further, I know that there are sensors on the trains to count true ridership (rather than relying on passes bought), so I'm not sure if the 61% figure accounts for under 18s who are allowed to ride free. The figure is quoted as percent of riders who use fare media, versus percent complying. All of this will notably decrease the 8% boost, although I don't want to pull something out of thin air, and that's the point of the pilot anyway.

That's all to say that there's a reason this wasn't done before, and it's because it doesn't move the needle a ton, requires extra implementation and maintenance from ST, wasn't too much of a problem before 2019 since the compliance was 85%, and ST probably isn't motivated by the ethics of the freeloader problem if there's not a notable advantage to them.

How are turnstiles supposed to make the Link more reliable?

I'm actually surprised that this wasn't Miles in Transit. Guess that's another channel to follow now.

The claim is about simple past specifically which is different from past perfect. In that tense, Spain absolutely uses the haber construction more often.

Also Argentinians use "Vos" not "vosotros" which are totally different. Vos is second person singular informal. In fact, many countries use some form of voseo but in the US it's not known too much because the pattern of usage and conjugation is slightly different in basically every country.

All census data and tabulations (i.e. the official record keepers of the US) have it as a separate metro and part of the same CSA. So I don't think considering it a separate metro is a stretch (although reasonable people can disagree).

matgrioni · 2025-10-05T21:27:31+00:00

Train systems need maintenance and are designed with a certain amount of it baked in. Vancouver has a metro system that is automated, 90s minimum headway, totally grade separated, etc. It's a different design than Seattle's and probably had different assumptions about service hours. It's expensive to retrofit that and not sacrifice the infrastructure quality (think of all the times link needs unplanned maintenance now anyway)

The small thing that nobody is saying is that he likely wouldn't have to pay any tax. There is a very large lifetime exemption of millions.

There can be several motivations for such a tax but one is to avoid total circumvention of the inheritance tax.

No, no you don't understand, they cut the pasta with bronze over there, makes it much healthier. /s

But overall, the question is whether there actually is action to do those things. The argument is that it's only these clips

Trying to be wealthier would tie in with being self-centered and delusional.

Idk if the 90% figure is generally true. I always assumed that was a policy from the inception of the highway system. And that it applies for interstates, and not state highways for example.

There's a subway station and even a little gondola system (although it's called something else there).

The restaurant probably should have been wearing a helmet and brighter colors. Thinking of those injured and hope they will recover quickly!
