@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

@zeynep Discussion of Y2K reminds me that we should be worrying about 2038 before it gets too close: https://t.co/wShFiKyiYP

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 🧵https://t.co/QgrMe9zYSL

@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.

[L. David Baron @[email protected] @davidbaron]

@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.

@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.

@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.)

@bgalbs @philikon @AliSapirman Indeed, visible in https://t.co/PXiFNzFxei .

I remembered them somewhere near Duveneck, but I only checked street view on the Alester side for some reason.

@AliSapirman Managed to find an old street view image at Channing & Webster:

[L. David Baron @[email protected] @davidbaron]

@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:

@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.

@ManishEarth Don't at least some of them think every physical system is *an* harmonic oscillator?

@flackrw @Litherum My first Mastodon account, from a few years ago, is in fact gone. (Maintainer didn't want to deal with the spam.) I'm now on my second account.

@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.

[L. David Baron @[email protected] @davidbaron]

@robinberjon @hsivonen The Web isn't subject to the particular power dynamic described upthread and in the opinion piece: removal from the store.

[L. David Baron @[email protected] @davidbaron]

@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.)

[L. David Baron @[email protected] @davidbaron]

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