Google asked Meta to switch to AndroidXR for their Quest devices. Meta said no and suggested Google offer Play Store on Quest, which Google rejected.

Google then went on a PR offensive accusing Meta of fragmenting the VR/AR ecosystem.

Meta is including this in the announcement to head off criticism by Google aimed at creating pressure on Meta to consolidate on AndroidXR.

This paradox is famously a case where the expected value of the game is infinite.

This isn’t what E2E means for communication software. E2E means only the participants have the keys. Signal is a good example of this, the message is encrypted from the sender to the receiver and Signal themselves cannot decrypt it.

Separately, most Zoom meetings are not E2EE. That’s why features like live transcription work.

New comment by traek in "Vickrey Auction"

A key property of a Vickrey auction is that it is incentive compatible, i.e. that it isn't possible to achieve a better expected outcome by bidding something other than your true valuation.

Your example relies on the telecom company (or any secondary buyer) not bidding in the auction or bidding only $4. A strictly dominant strategy for the telecom company would be to bid $100k in the auction, winning it for $60k (the second-highest price).

Oops, cut off the quote too early, it was in response to "Is it possible that someone at your university was tricked?"

The list is real and it is part of a LEED standard. Technically it's compiled by ACEEE and just referenced by USGBC, but it's a real thing and not trickery.

> I’m slightly confused by the existence of that list, USBGC provides LEED certification to buildings, not cars, right?

No, LEED credits are given to buildings for providing incentives for low-emitting vehicles.

> I haven't seen a single one of these and with the Chinese market as large as it is I'm sure that they could stay away from other markets for a long time without exporting their BEVs to countries where they will have to face competition from established Western brands.

Sure, but they aren’t. These Chinese EV manufacturers are coming for the world market.

Volvo is now owned by a Chinese company, Geely, and they’re manufacturing EVs in China based on a Geely platform for global export[0]. Polestar, also owned by Geely, is a Western market EV brand exported from China[1]. BYD is already planning to build factories and sell cars in Europe[2].

> It's somewhat surprising to hear that requests would be rejected if the user agent doesn't match a set of hard coded IP addresses.

It’s fairly common for DDoS/scraping prevention, Googlebot (and most other crawlers) publish their IP ranges for that reason[0][1][2]. I don’t work at Cloudflare though, so no insider knowledge of what you folks are doing.

> Still, if it means Google is investing in Matrix, that's a good thing. I always worry at some point it will be killed.

This isn't Google investing in Matrix, this is a group of people who work at Google using their spare time to rewrite the product so it doesn't get taken offline.

If anything, the lack of a dedicated team or resources is a strong indicator that Matrix will be on the chopping block at some point in the future.

New comment by traek in "Twitter rolls back AMP support, no longer sends users to AMP pages"

traek — Thu, 18 Nov 2021 20:02:32 +0000

The original article is talking about traffic from Twitter to publisher sites, not traffic from Google to Twitter. Twitter never used AMP for pages on their own site.

In this case Twitter is the platform, not the publisher, and would absolutely have been able to not use the Google cache.

> Now, when using one of Twitter's mobile clients, users will be sent to the amphtml URL in their browser, instead of the link that was shared in the Tweet. Users will load this link directly, not via a page cache. [0]

This would only be correct if stickiness (the DAU/MAU ratio) were around 3%, i.e. if each MAU only visited once per month.

> I'm not sure how 21% lower is considered "not statistically significant", in trying to suppress the spread, ANYTHING > 0% is helpful. Full stop.

Statistical significance has a specific meaning in the context of hypothesis testing. It is a measure of likelihood that the observed result occurred due to a real difference between groups (rather than random chance).

They aren't saying that the feature gating code adds to app size, but rather that there's a lot of code behind feature gates (for tests/staged rollout/locale-specific features/etc) that most users won't see which still add to app size.

That's not a feature of advertising as a business model, it's just a feature of growth-focused businesses. The same forces apply to products that you pay for with money. For a very obvious example, just look at Candy Crush.

No, there’s no reason to want to go OTC for just 20k and most desks won’t will deal with you for that amount. That isn’t even half a BTC at current prices, every major exchange has the market depth to support that.
