traek··on Meta Horizon OS
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.

traek··on Sam Bankman-Fried is going to jail
This paradox is famously a case where the expected value of the game is infinite.
traek··on Following pushback, Zoom says it won't use customer data to train AI models
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.

traek··on 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).

traek··on The Swivel-Eyed Loons Have a Point
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.

traek··on The Swivel-Eyed Loons Have a Point
> 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.

traek··on China’s BYD is overtaking Tesla as the carmaker extraordinaire
> 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].

traek··on How to Bypass Cloudflare: A Comprehensive Guide
> 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.

traek··on Help pick a syntax for CSS nesting
It's accessible on any browser, you'd just need to scroll to the section manually if your browser doesn't support text fragment links.
traek··on Google 20% time volunteers have been rewriting the ITA Matrix flight search app
> 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.

traek··on Twitter rolls back AMP support, no longer sends users to AMP pages
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]

traek··on Results from being #1 on Hacker News for 6 hours
This would only be correct if stickiness (the DAU/MAU ratio) were around 3%, i.e. if each MAU only visited once per month.
traek··on Norwegian Data Protection Authority choose not to use Facebook
I'm surprised they didn't apply this analysis to their Twitter page as well.
traek··on The Coronavirus Is Here Forever
> 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).

traek··on Facebook is now claiming official CDC.gov links are “False Information”
All of this is also true for our actual government[0]. I have zero confidence that if our government were in charge of running Facebook/Twitter/any other social media app the results would be better.

traek··on How I, as someone who is visually impaired, use my iPhone (2020)
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.
traek··on Why I Work on Ads
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.
traek··on Turkey bans use of cryptocurrencies for payments
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.
traek··on What’s interesting about the Florida water system hack is that we heard about it
There's a ton of literature out there on America's infrastructure problems.

This is a good summary from a neutral source: https://www.cfr.org/backgrounder/state-us-infrastructure

traek··on Tencent is acquiring a majority stake in Klei Entertainment
TikTok is owned by ByteDance, not Tencent.
traek··on Visa Advertising Solutions (VAS) Opt Out
Yes, by checking the SSL cert.
traek··on Helsinki Relocation Package: City as a Service
They're all paid into by workers, taxes are taxes.
traek··on Facebook has sent a cease-and-desist letter to researchers
CA data was from a quiz, developed by a researcher at Cambridge University, hosted by that researcher, which scraped FB APIs after being authorized by a user.

This data is from a browser extension, developed by researchers at NYU, hosted by those researchers, which scrapes the FB site after being installed by a user.

IMO the situations are pretty analogous.

traek··on Dropbox Converts to Permanent WFH
Individual Contributors (i.e. non-managers).
traek··on The Prize in Economic Sciences 2020
The link explains some practical applications of Milgrom's and Wilson's work on auction theory. Mechanism design and auction theory are definitely predictive and useful in the real world.
traek··on Y Combinator Failed Startups
Did they go through YC? I can't find anything online about that, but I had no clue they raised $10M from Sequoia. Surprising.
traek··on Law firms pay Supreme Court clerks $400k bonuses – what are they buying?
This explains why law students apply to clerkships, not why firms pay bonuses for former clerks.
traek··on An Update About Changes to Facebook’s Services in Australia
Where are you reading that this affects New Zealand?
traek··on TikTok Inc. vs. U.S. Department of Commerce
The partners aren’t the ones working nights to draft these documents.
traek··on Former Zoox employees sue, alleging rival offer was better than Amazon's
It is absolutely true that the board has a fiduciary duty to shareholders, and many states have statutes specifically protecting minority shareholder rights. Delaware is fairly unfavorable to minority shareholders though.
