...with stray light coming in from all sides because glasses don't cover your face completely. So the best place to use them will probably be a completely darkened room?

Unless like Vision Pro there's a surroundings control that lets you go from total visibility outside the image to complete darkness — within the FOV — in any environment.

Edit: Since the FOV is only 70 degrees, that leaves 110 degrees outside the image, divided between the edges of the glasses and the rest of the room. So for sure in daylight outside light would destroy the theater effect.

Apparently there is a flap you can place on them to block out light.

There is a "pace car" in Formula One too, although the name is informal, the official term is "safety car"...

Maybe it's clear to native speakers, but both "pacing" and "frontier" have multiple meanings. "Pace" as a verb means literally just walking, as a noun it's the speed at which something progresses. So I'm not sure that everyone reading this phrase will immediately realize that "pace" actually means slowing down the pace of development (having "slow" in the phrase would have probably sounded too negative). Also, it's not immediately intuitive that "frontier" refers to frontier AI models.

Actually, when I first read "pacing the frontier", the first thing that came to my mind was a border guard patrolling a border by foot...

> The shade supports don't have to hold up solar panels: Shade supports cost less.

If you look at the photos, the solar panels are mounted directly on the supports. If you wanted a simple shade for the canal, you would have to mount some kind of roof on the supports instead of the solar panels. Granted, the solar panels probably weigh a bit more than simple sheet metal, but that is probably more than made up for by the benefit of generating power.

PV itself (not the inverters etc., the panels) is really really cheap.

Tarp is about the only opaque covering I've found that's cheaper than PV, per square meter.

However, even for a balcony PV system the frame is about 25% the price of the panel, and balcony systems are tiny frames; I don't want to even guess about those huge steel I-beams and concrete pads. For big things like this, the cost of the frame is unlikely to go away because you need to care about wind load.

That really leaves maintenance costs (how often do you need to replace the tarp?) and revenue (PV makes money, a tarp does not).

Based on my experience in NM (higher elevation, similar insolation), the expected life of tarp-like materials in open sunshine here would be 2-3 years.

Sunshade material could be more like 5-8 years, but is significantly more expensive.

That sounds like a huge maintenance headache.

A Concrete slab is usually even cheaper.

not if you want to suspend it above the water.

Tarp, and pitch it across the canal like how you might do a hammock - you just need two anchor points on each side (or 4, at most).

We’re discussing permanent cover. A tarp barely lasts a year (or 3 if using very heavy duty fabric).

The point still stands. Regular transit users generally don't pay per ride, they use monthly passes. Or aren't those a thing in San Francisco?

It's possible to implement weekly/monthly passes on credit/debit cards too via capping, but it's indeed a bit more annoying and unpredictable. For example, NYC MTA weekly capping breaks if you ever remove and re-add your card to your phone. (And I can understand how not all transit agencies want to offer capping.)

Well, Waymo could be seen as a last mile connectivity program. That's actually the "end goal" for robotaxis: not just replace taxis, Uber etc., but offer an alternative to owning a car.

> Over the past 30 years, World Wide Words has chronicled the shifting English wordscape

I know, 30 years ago it was probably very tempting to have a website with a name that could be shortened to WWW, but still, it's a bit strange that a site with such a name only focuses on English?

The site appears to have been maintained by a single man from the UK. It's not strange.

> Our findings reveal the sheer scale of branding embedded throughout tournament broadcasts, making exposure to unhealthy food, alcohol and gambling brands both omnipresent and unavoidable for viewers.

Do we really need an academic study to tell us that yes, there were ads on the sides of the football pitch at the World Cup, and that FIFA's choice of sponsors is questionable (but hey, questionable sponsors pay better than less questionable ones)?

To quote one of my teachers, "you may read the Constitution and think it's all obvious, that it's like writing a law that says people need air to live. The problem is, if you don't explicitly write it down someone may actually try to steal the air".

I didn't need someone to tell me that FIFA is full of ads. But studies like this provide a precise, measurable target to work with.

also in the thread about OONI censorship measuring program people said they don't need a study to know China censors the internet

Cool, but I hope it doesn't catch on. Otherwise I can already hear managers complaining to people that they have too many red words and not enough green words in their emails/Slack messages/whatever...
