The designated stroller space is so key... Same feature (right across from the huge middle doors, in an area with no seats to enable maximum I/O movement) is present in Vienna. One of the reasons it's so much less stressful with a stroller there than on NYC buses

Tbh if it’s two floors or less on the subway, I usually find it more convenient/faster to just carry the stroller up the stairs. Only really got screwed once, when the elevator at Lex / 53 EM was out of service (and so was the escalator) and I was carrying it up out of that crazy cavern 😩

For these reasons, we cannot simply look to trends in mean precipitation, or mean evaporation, to tell us anything about changes in *extreme* precipitation or evaporative demand (i.e., atmospheric "thirst"). To do so would be deeply misleading. Yet it remains common practice.

BREAKING: Federal agencies paid a private cloud seeding company to spray Texas skies—just 2 days before deadly floods killed 60+. No public comment. No oversight. No accountability. Call it weather modification. Call it a conspiracy. But it’s happening.

(biased, but even though I love HafenCity, I think the Viennese are better at that game than the Hamburgers ;) But HafenCity definitely is more applicable in the port context. As long as one doesn't feel the need to replicate the U-shaped missed-connections-heavy U-Bahn line, hah!)

Adding a plug for the absolutely lovely Viennese tram- (Nordbahnviertel, Sonnwendviertel) or subway- (Aspern, though that will eventually also get a tramway, several other smaller infills along the U2, and the future Rothneusiedl dev)-and-park-centric new dense, mixed-use urban development zones.

Also very looking forward to level boarding on the fed. railways (WESTbahn had been running Stadler double-decker EMUs for a while; but these days the ÖBB is cheaper if you have a discount card + has timed connections to regional rail lines along the way, which I often take to reach the main line)

The extra capacity on the intercities is very needed - despite 2+ tph by the federal railways and 1-2 tph by the private operator WESTbahn, trains, especially on Fri / Sun, are often completely packed, many standees. + the EMUs should speed up the all-stop service over the current loco-hauled one!

New Austrian double-decker EMUs had their interiors revealed today - they’ll be running the all-stop intercity services on the western railway line to Salzburg from Vienna come the 2026 timetable change. Check out the train simulator in the kid’s section!!

Not just at tiny stations, this happens at Penn!! (At least at one incredibly dumb platform)

Also would reduce the issue of that one platform in Penn that’s too short for the longest LIRR trains, where I ended up crossing over between married pairs to get out of the train once (real happy no one was in a wheelchair or with a stroller that time…)

Donald Duck comics are still a huge regularly sold thing in the German speaking world (in the format of Lustige Taschenbücher - “merry pocketbooks”); or at least were still when I was growing up in the aughts. Still sold in checkout lines and convenience stores. Never really seen any in the US 😅

Probably the chillest transfers I’ve had have all been Nordic - KEF, CPH, ARL. ZRH in theory not bad, but the US was particularly zealous with handing out SSSSes there for years for some reason - multiple times over half the plane got pulled aside

Ooof hard disagree on AMS, FRA, DUB - the former two I’ve always been stressed and running a mile, in Dublin i always end up having a connecting flight in the dumb satellite terminal with no amenities and too little seating with a 200ft bus ride to get there :/ (Really miss flying through KEF tho)

I suspect that fact that the vast majority of LLM users don’t seem to have received this (really very simple!) message is because the AI companies have a vested interest in us not understanding it. “ChatGPT is smart, it just makes mistakes sometimes” is much more marketable than the truth.

Chatbots — LLMs — do not know facts and are not designed to be able to accurately answer factual questions. They are designed to find and mimic patterns of words, probabilistically. When they’re “right” it’s because correct things are often written down, so those patterns are frequent. That’s all.

The massive speed improvements on the Austrian west railway by a private operator (WESTbahn, an open access operator) who used EMUs instead of loco-hauled trainsets (the European original of the Venture sets coming to Amtrak soon, incidentally) seems informative here too…

Like did people generally agree what “fruits” and “vegetables” were, and then scientists mapped the name “fruit” onto “seed-bearing structures of flowering plants”, which then awkwardly expanded the definition to other things? (Or botanists* not sure about which field would do this)

So a question I’ve always had here - was the distinction between fruits and vegetables at first culinary and was then imperfectly mapped onto biological traits by ecologists, or did def of either just expand over time to cover things that used to be called the other culinarily?

(though tbh the "all the lights turn on when the train is recoupled" is a software issue that presumably can theoretically be fixed... the broader question is, which routes would fill up and be efficient to run directly instead without swapping train cars in Nürnberg or whatever)

This is the way, wish ÖBB did more routes a bit like that. The middle of the night “all the lights turn on for some reason” that comes with reshuffling the consists is obnoxious. (And fewer middle of the night stops close together probably cuts down on theft too, which is an issue on some routes)

the newest JP Morgan climate risk report was released yesterday, this one focused on ports. the thing that stands out to me is just how much finance needs not only government data, but academia to interpret it. the main data on port risk come from open access articles like Nature Climate Change
