‘If You Die in the Game, You Die in Real Life.’

Oculus co-founder Palmer Luckey, writing on his personal blog: Today is November 6th, 2022, the day of the SAO Incident. Thousands of VRMMORPG gamers were trapped by a mad scientist inside a death game that could only be escaped through completion. If their hit points dropped to zero, their brain would be bombarded by extraordinarily powerful microwaves, supposedly killing the user. The same would happen if anyone in the real world tampered with their NerveGear, the virtual reality head-mounted-display that transported their minds and souls to Aincrad, the primary setting of Sword Art Online.

[…] In SAO, the NerveGear contained a microwave emitter that could be overdriven to lethal levels, something the creator of SAO and the NerveGear itself (Akihiko Kayaba) was able to hide from his employees, regulators, and contract manufacturing partners. I am a pretty smart guy, but I couldn’t come up with any way to make anything like this work, not without attaching the headset to gigantic pieces of equipment.

In lieu of this, I used three of the explosive charge modules I usually use for a different project, tying them to a narrow-band photosensor that can detect when the screen flashes red at a specific frequency, making game-over integration on the part of the developer very easy. When an appropriate game-over screen is displayed, the charges fire, instantly destroying the brain of the user. This isn’t a perfect system, of course. I have plans for an anti-tamper mechanism that, like the NerveGear, will make it impossible to remove or destroy the headset.

Even so, there are a huge variety of failures that could occur and kill the user at the wrong time. This is why I have not worked up the balls to actually use it myself, and also why I am convinced that, like in SAO, the final triggering should really be tied to a high-intelligence agent that can readily determine if conditions for termination are actually correct. At this point, it is just a piece of office art, a thought-provoking reminder of unexplored avenues in game design. It is also, as far as I know, the first non-fiction example of a VR device that can actually kill the user. It won’t be the last.

Now Wordle Has An Editor In Charge of Picking the Next Answer

Wordle will now have its own dedicated editor to help make the hit guessing game word puzzles, The New York Times announced on Monday. The Verge reports: Tracy Bennett will be the editor, and the game will have a word list curated by the NYT and “be programmed and tested” like its crosswords and the Spelling Bee game. The changes appear to mean that the NYT will be lining up some of its own solutions instead of relying on the long list of answers you could find if you knew where to look. However, it sounds like the game itself won’t be changing.

“Wordle’s gameplay will stay the same, and answers will be drawn from the same basic dictionary of answer words, with some editorial adjustments to ensure that the game stays focused on vocabulary that’s fun, accessible, lively and varied,” Everdeen Mason, the NYT’s editorial director of games, wrote in an article about Bennett’s appointment. You might already be seeing a different answer than someone else as a result of the change. If that’s the case, Mason suggests refreshing your browser or playing the game on the Crossword app.

Microsoft Is Exploring Energy-Saving Graphics Modes For Xbox and Windows Games

A new survey on the Xbox Insider Hub suggests Microsoft is looking to expand on its energy saving features for Xbox consoles and potentially PC games too. Jez Corden writes via Windows Central: A recent questionnaire I came across in the Xbox Insider app on Windows PC detailed a potential list of new features Microsoft is exploring for games across consoles and PC. These new features pertain specifically to opting-in to reduce frame rates, resolution, and so on, with the goal of limiting energy consumption. Of course, surveys don’t necessarily mean that these sorts of features will make it into a final product, but Microsoft’s commitments to net zero carbon use have seen the firm increase its investments in this space.

The survey asks users about their current feelings with regard to energy consumption, potentially polling users on how the energy crisis is affecting their willingness to spend. The survey asks users if they would be interested in features that reduce power consumption in games, both while the games are running and while they’re inactive, specifically to save energy and thus money. Microsoft also asks users how they would prefer these features to be branded, with terms like “eco-saving” and “energy-saving,” and even asks if these sorts of features would affect users’ purchase decisions per game.

Apple’s AR Glasses Could Slip To 2026, Says Analyst

While Apple is still expected to release its first VR/AR headset next year, the bigger step to mainstream adoption — the Google Glass-style AR glasses — may have slipped two years according to one analyst. Tom’s Guide reports: In an email to MarketWatch, Haitong International Tech Research’s Jeff Pu wrote that Apple Glasses could now be up to four years from making their first appearance. “We now expect the AR Glass to be postponed to 2025-2026, due to design issues,” Pu wrote. This is significant as just five months ago Pu stated that the AR glasses could be announced as soon as 2024.

The term “design difficulties” is, of course, a bit of a catch-all. It could cover anything from making the glasses aesthetically pleasing and light enough for extended wear, to ensuring they have enough battery life to be useful and don’t overheat. But it’s striking that nearly a decade after Google Glass became available to ‘Explorers’ in the US, companies are still struggling to make the form factor work, despite the considerable technological improvements we’ve seen in the intervening years.

Japan Seeks Power To Turn Down Private Home Air Conditioners Remotely, Report Says

Japan Today reports: As reported by Japan’s Nihon Keizai Shimbun, in a meeting on Nov 2, the Energy Conservation Subcommittee of the Ministry of Economy, Trade and Industry resolved to begin working group discussions with the aim of gaining the ability to remotely turn down privately owned air conditioner/heater units. The goal would be to decrease energy usage during expected power shortages, which the committee feels are a growing concern as Japan attempts to shift towards renewable energy sources such as solar power, where the amount generated can be affected by day-to-day climate, making it difficult to stabilize the amount of total power available. The ministry says that AC unit usage accounts for roughly 30 percent of household electricity consumption in Japan.

From a technical standpoint, the plan wouldn’t be particularly difficult to implement. Japanese air conditioner units have long had remote controls, so external inputs aren’t a problem, and many models now allow the owner to turn the system on and off or adjust temperature settings through the internet. By asking manufacturers to extend such access to government regulatory organizations, and granting those organizations override functions over other inputs, the plan could easily be put into practice for internet-connected AC units, and water heaters are another home appliance the committee is looking to gain the ability to throttle back. […] According to Nihon Keizai Shimbun, the committee is currently working under the concept that the government would only be able to turn down AC units if their individual owners have agreed, in advance, to grant that authority.

Psychedelic Mushroom Dose Can Treat Stubborn Depression, Trial Suggests

The Washington Post reports:

Psilocybin, the active hallucinogen found in psychedelic mushrooms — also known as “magic mushrooms” — can effectively alleviate a severe bout of depression when administered in a single dose and combined with talk therapy, a new clinical study found.

Adults with depression who were administered a single 25-miligram dose of psilocybin were more likely to experience significant improvements in their mental health — both immediately and for up to three months — than others who were randomly assigned smaller doses of the same drug, said the peer-reviewed study, which was published Wednesday in the New England Journal of Medicine….

The trial’s findings could be an encouraging sign for the 16 million Americans estimated each year by the Centers for Disease Control and Prevention to have depression, many of whom struggle to find treatments that work for them. Its authors hope the study — which was relatively small, with just 79 participants receiving the 25 mg dose — will pave the way for eventual regulatory approval of psilocybin by the Food and Drug Administration for use as a drug against depression….

Notwithstanding the headaches, nausea and dizziness reported by many as adverse side effects, most of the adults enjoyed the experience.
The Post got an interesting reponse from James Rucker, a consultant psychiatrist at King’s College London who worked on the trial. He said there’s something about the psychedelic experience that leads to a rapid resolution of depression symptoms, adding “We don’t really know what that is at the moment, but it’s very different to standard antidepressants….”

“What people forget about psychedelics is that they were being used as medicines prior to 1971 when they essentially got caught up in the drugs war,” Rucker added. “We’re just picking up the baton of history.”

New York City Finally Proposes Strict New Regulations for Airbnb Rentals

New York City “is pressing ahead with a long-anticipated crackdown on Airbnb hosts,” reports the New York Post, “with officials on Friday proposing a strict new registration system for hosts that will take effect in January.”

There’s 30 pages of rules…

Under proposed rules that were quietly and unexpectedly made public on Friday — which will, among other things, prohibit hosts from renting out an “entire registered dwelling unit” — Airbnb hosts will be required to submit diagrams of their apartments as well as proof that their listings are permanent residences. Hosts also will be required to list the “full legal name of all permanent occupants of the dwelling” as well as their relationship to the host….

If hosts fail to comply, they can be fined up to $5,000 under the new rules, while Airbnb and other platforms are required to verify the rental on its systems and could be on the hook for a $1,500 fine per violation. Last year, the city council passed the registration law, but little was known about the details and requirements, which will become effective Jan. 9 and enforced by May 9….

Among the requirements, said the source, is one that bars hosts from putting locks on doors that separate the guest from the host, directing that “a registered host shall not allow a rentee to have exclusive access to a separate room within a dwelling” and specifying that, for example, “providing the rentee with a key to lock the door when such rentee is not in the dwelling is prohibited….”

It’s the latest salvo in the fraught relationship between New York City and Airbnb, which has long pushed back on the city’s efforts to regulate the industry. Meanwhile the city blames Airbnb, in part, for its housing shortage.

Could ‘Ghost Particle’ Neutrinos Crashing Into Antarctica Change Astronomy Forever?

CNET reports on how research in Antarctica “could change astronomy forever”:

About 47 million light-years from where you’re sitting, the center of a black-hole-laden galaxy named NGC 1068 is spitting out streams of enigmatic particles. These “neutrinos” are also known as the elusive “ghost particles” that haunt our universe but leave little trace of their existence…. Nestled into about 1 billion tons of ice, more than 2 kilometers (1.24 miles) beneath Antarctica, lies the IceCube Neutrino Observatory. A neutrino hunter, you might call it. When any neutrinos transfer their party to the frigid continent, IceCube stands ready.

In a paper published Friday in the journal Science, the international team behind this ambitious experiment confirmed it has found evidence of 79 “high-energy neutrino emissions” coming from around where NGC 1068 is located, opening the door for novel — and endlessly fascinating — types of physics. “Neutrino astronomy,” scientists call it.

It’d be a branch of astronomy that can do what existing branches simply cannot.

Before today, physicists had only shown neutrinos coming from either the sun; our planet’s atmosphere; a chemical mechanism called radioactive decay; supernovas; and — thanks to IceCube’s first breakthrough in 2017 — a blazar, or voracious supermassive black hole pointed directly toward Earth. A void dubbed TXS 0506+056. With this newfound neutrino source, we’re entering a new era of the particle’s story. In fact, according to the research team, it’s likely neutrinos stemming from NGC 1068 have up to millions, billions, maybe even trillions the amount of energy held by neutrinos rooted in the sun or supernovas. Those are jaw-dropping figures because, in general, such ghostly bits are so powerful, yet evasive, that every second, trillions upon trillions of neutrinos move right through your body. You just can’t tell….

Not only is this moment massive because it gives us more proof of a strange particle that wasn’t even announced to exist until 1956, but also because neutrinos are like keys to our universe’s backstage. They hold the capacity to reveal phenomena and solve puzzles we’re unable to address by any other means, which is the primary reason scientists are trying to develop neutrino astronomy in the first place…. Expected to be generated behind such opaque screens filtering our universe, these particles can carry cosmic information from behind those screens, zoom across great distances while interacting with essentially no other matter, and deliver pristine, untouched information to humanity about elusive corners of outer space.

The team says their data can provide information on two great unsolved mysteries in astronomy: why black holes emit sporadic blasts of light, and neutrinos’ suspected role in the origin of cosmic rays.

Mastodon Continues to Grow – But Still .27% the Size of Twitter

By Tuesday morning Mastodon had gained 123,562 new users since October 27 (the site told TechCrunch) and had 528,607 active users. But by Saturday the number of new users had nearly doubled, to 230,000, reports CNN — with 655,000 active users.

In fact, for every 363 active users on Twitter, there’s now one on Mastodon, CNN’s figures suggest (since Twitter has nearly “238 million daily active monetizable users”). Exploring the recent spike, they note that Mastodon “has a similar look to Twitter, with a timeline of short updates sorted chronologically rather than algorithmically. It lets users join a slew of different servers run by various groups and individuals, rather than one central platform controlled by a single company like Twitter, Instagram, or Facebook.”

Unlike larger social networks, Mastodon is both free to use and free of ads. It’s operated by a nonprofit run by Mastodon creator Eugen Rochko, and is supported via crowdfunding… “It is not as large as Twitter, obviously, but it is the biggest that this network has ever been,” said Rochko, who originally created Mastodon as more of a project than a consumer product (and, yes, its name was inspired by the heavy metal band Mastodon)….

A lot of Mastodon’s features and layout (particularly in its iOS app) will look and feel familiar to current Twitter users, though with some slightly different verbiage; you can follow others, create short posts (there’s a 500 character limit, and you can upload images and videos), favorite or repost other users’ posts, and so on…. There are some key differences, particularly in how the network is set up. Because Mastodon users’ accounts are hosted on a slew of different servers, the costs of hosting users is spread among many different people and groups. But that also means users are spread out all over the place, and people you know can be hard to find.

CNN also notes the problem with signing up for a Mastodon server: “some of which are open to anyone, some of which require an invitation (you can also run your own server). There is a server operated by the nonprofit behind Mastodon, Mastodon.social, but it’s not accepting more users.”

Although trending on the server I found today: #Caturday photos.

New Features In Rust Include Generic Associated Types (GATs) After Six-Year Wait

The newest stable version of Rust, 1.65.0 includes generic associated types (GATs) — the ability to declare lifetime, type, and const generics on associated types. “It’s hard to put into few words just how useful these can be,” writes the official Rust blog.

An earlier post pointed out that “There have been a good amount of changes that have had to have been made to the compiler to get GATs to work,” noting that the request-for-comments for this feature was first opened in 2016.

And Rust’s types team also created a blog post with more detail:
Note that this is really just rounding out the places where you can put generics: for example, you can already have generics on freestanding type aliases and on functions in traits. Now you can just have generics on type aliases in traits (which we just call associated types)….

In general, GATs provide a foundational basis for a vast range of patterns and APIs. If you really want to get a feel for how many projects have been blocked on GATs being stable, go scroll through either the tracking issue: you will find numerous issues from other projects linking to those threads over the years saying something along the lines of “we want the API to look like X, but for that we need GATs” (or see this comment that has some of these put together already). If you’re interested in how GATs enable a library to do zero-copy parsing, resulting in nearly a ten-fold performance increase, you might be interested in checking out a blog post on it by Niko Matsakis.

All in all, even if you won’t need to use GATs directly, it’s very possible that the libraries you use will use GATs either internally or publically for ergonomics, performance, or just because that’s the only way the implementation works…. [A]ll the various people involved in getting this stabilization to happen deserve the utmost thanks. As said before, it’s been 6.5 years coming and it couldn’t have happened without everyone’s support and dedication.
Rust 1.65.0 also contains let-else statements — a new kind of let statement “with a refutable pattern and a diverging else block that executes when that pattern doesn’t match,” according to the release announcement.

And it highlights another new feature:

Plain block expressions can now be labeled as a break target, terminating that block early. This may sound a little like a goto statement, but it’s not an arbitrary jump, only from within a block to its end. This was already possible with loop blocks, and you may have seen people write loops that always execute only once, just to get a labeled break.

Now there’s a language feature specifically for that! Labeled break may also include an expression value, just as with loops, letting a multi-statement block have an early “return” value.
