@anatudor @bramusblog Maybe worth noting that .a :is(.b .c) matches a slightly larger set of things, since it matches everything matched by:
.a .b .c
.b .a .c
.a.b .c

@bramusblog To make it clear: I cannot think of *any* use cases for the `:is(.b .c)` part in isolation and the only use case for the whole `.a :is(.b .c)` would be precisely to also select `.b .a .c` in addition to `.a .b .c`.
English
Using `:is()` in complex selectors selects more than you might initially think.

@zeynep Discussion of Y2K reminds me that we should be worrying about 2038 before it gets too close: en.wikipedia.org/wiki/Year_2038…
English
Yes! Just *today* I saw a viral tweet referring to the Y2K bug as a "conspiracy."
Just the US spent ~$100 billion to fix it—a multi-year effort.
When infrastructure functions as it should, it recedes from our attention.
That doesn't mean it's not there.

Southwest's antiquated scheduling software had caused meltdowns before.
Unions begged for modernization. Didn't happen.
$8.5 billion excess cash went to stock buyback.
After the storm, pilots & crew had to call in—manually.
Hours on hold.
Couldn't fly.

Thrilled to share "Regulating the Pedestrian Safety Crisis," just published
The motivation was simple: ped deaths are up 50%+ since 2010, but @NHTSAgov is the only responsible agency that has failed even to notionally prioritize pedestrian safety. Short 🧵ssrn.com/abstract=41765…

@EmilyKager So, sure, *I* could afford to stay... but it wasn't clear how long the society I was staying in would continue to function.
English
@EmilyKager It really starts to feel like the cost of housing would lead to some sort of societal collapse where many of the professions that society depends on would no longer be present in the region.
English
i love San Francisco a lot but if you start to think about it too much it's extremely depressing thinking about the long term realities and restrictions of living in a VHCOL area
English
@khuey_ @opinonhaver Also, that may (??) be an expensive house price in the suburbs of Richmond, but it isn't one in the suburbs of DC.
English
@opinonhaver There's no way median household income in Scranton is 78k.
English
It’s wild to me as a Californian that the $335k is considered an “expensive” neighborhood lmao
Matt Karp 🌹🦏🇺🇸@karpmj
Will the Democrats aim to be the party of Abigail Spanberger and the Va. suburbs (median household income $116k/yr; average home price, $335k) Or Matt Cartwright and the party of Scranton, Pa. (median hh income $78k, avg home price, $172k)?

@BenRossTransit @greg_shill @Jeffinatorator And there's still a bunch of suburban office park construction happening in Rockville, filling in areas near Adventist Hospital.
(Also planning for the Belward Farm site nearby.)
English
@greg_shill @Jeffinatorator In DC area, the vacancies are worst in the suburban office parks. Which are not where you want your work-in-the-office startup. Suburban walkable centers seem to be doing best, landlords there may be waiting for relocations as office park leases run out.
English
The great thing about this is that it works regardless of how you value the 8+ hours x 5 days a week in person model. Eg, if you’re a founder who can get more value out of that than hybrid or remote, you have oodles of great office space available to you at attractive prices.
Adam Ozimek@ModeledBehavior
Office vacancies are at a 30 year high, tech layoffs are creating a supply shock of skilled labor, and there are tons of skilled remote workers eager for remote jobs. What a great time to do a startup!

@bgalbs @philikon @AliSapirman Indeed, visible in maps.app.goo.gl/qibNxQMFPUJMv5… .
I remembered them somewhere near Duveneck, but I only checked street view on the Alester side for some reason.
English
@philikon @davidbaron @AliSapirman Channing and Heather in Palo Alto had them for a while a few years back. I think they gradually disappeared, I can’t remember seeing them in years.
English
I was in downtown Willow Glen today. They gave this flag system for crossing the street, have you seen this anywhere else?
English
@AliSapirman Managed to find an old street view image at Channing & Webster:
maps.app.goo.gl/nCGnCGDKjYZiMk…
English
@AliSapirman Definitely seen it somewhere else. It was probably near a school in Palo Alto, but I can't recall where, and can't find it on street view.

What a great summary of the debate on social discount rates (SDRs), from Milner and Heal:

English
@drvolts A system like the UK's that has fewer checks and balances might help. The Tories don't campaign to end the NHS because the NHS is popular, and people know that if they wanted to end it, they could. US Rs campaign on things they don't intend to do; it gets the base excited.
English
But I would put it to you that that's only half the story. Liberal democracies also need ways to *end* arguments. When one side obviously has the right of it, there needs to be some way to wrap it up, to incorporate the winning argument into our shared knowledge base & act on it.
English
Rather than doing something useful, I feel like writing a thread that's been on my mind for a while. You will not be shocked to hear that it's related to epistemology. Yes, I'm on that old bullshit again.
So, let's talk about arguments.
English
@ManishEarth Don't at least some of them think every physical system is *an* harmonic oscillator?
English
physicists love to think every physical system is a harmonic oscillator, and every mathematical quantity is a group
so of course our leading theory of the universe is what happens when you use group theory on harmonic oscillators
\newcommand{\femb0t}{@__femb0t
people like to joke that physicists think everything is a harmonic oscillator. but this is because everything is a harmonic oscillator

@Litherum There is a mechanism for moving an account to another server and I think most servers will have some notice they’re going away. screenrant.com/mastodon-chang…
English
I don’t understand how to sign up for Mastodon. I have to choose a server? What happens if the people running the server take it down? Is my account just gone? Why do I have to distinguish between “game developer litherum” vs “social litherum” vs “tech professional litherum”?

@Scholars_Stage I saw much more military presence visiting Seoul than I did visiting Taipei.
Though there is always the warning about photography being forbidden during approach to Taoyuan Airport, which gives an expectation of it...

@ElliottZ @alexanderdanilo @robinberjon @rocallahan @hsivonen Mozilla probably had the advantage that more other companies were willing to help.
English
@davidbaron @alexanderdanilo @robinberjon @rocallahan @hsivonen I'd argue it was a mistake in strategy. MS spent billions trying to get their foot in the mobile door and failed. Mozilla never had pockets that deep to start with.
English
And, yet, when I read the New York Times on the Web, the site tries to get me to switch to the app and requires me to tap away the annoyance to stay on the Web. I guess whatever NYT gets out of readers using the app outweighs the risk to journalistic independence.
English
@robinberjon @hsivonen The Web isn't subject to the particular power dynamic described upthread and in the opinion piece: removal from the store.
English
@alexanderdanilo @robinberjon @rocallahan @hsivonen I don't think it's clear what about Firefox OS was a mistake in strategy versus a mistake in execution. (There were plenty of the latter.)
English
@robinberjon @rocallahan @hsivonen Sadly the leadership went on a tangent and built Firefox OS which in hindsight was a mistake - engineering resources taken away from the browser to an ultimately failed project. Meanwhile, Opera caved and killed off Presto as the main engine while reinventing itself as an ad mob

@greg_shill I caught it because it didn't work.🫤
