FTX Contagion Is Spreading To the Solana Ecosystem

Solana’s SOL is down much further than any of the other major cryptocurrencies today, all of which are down badly following the sudden unraveling of the wildly fast growing crypto exchange FTX on Tuesday. Axios reports: Blockchain principles aim to instantiate the ideals of decentralization. That is, no single points of failure. Blockchain realities, though, show that each community tends to have its major leaders. For Solana, one of those was definitely FTX’s c0-founder, Sam Bankman-Fried (SBF). SBF has long been bullish on Solana, including working to build Serum, an order book style exchange that runs in a decentralized fashion. His firms are rumored to have owned a substantial amount of the total SOL supply.

FTX and Alameda Trading are in trouble. If they hold large amounts of SOL, they are very likely to exit those positions, which will tank SOL price. CoinDesk reported on Nov. 2 that Alameda had $292 million in SOL and $863 million in locked SOL (on the Solana blockchain, large holders can earn more by backing the blockchain’s validators by committing not to sell — or locking — for a certain period of time). “People are dumping already — self-fulfilling prophecy,” Economics Design’s Lisa Jy Tan told Axios over Twitter DM. Tomorrow, the entities verifying the Solana blockchain have already publicly indicated their intention to unlock about a billion dollars worth of SOL (at current prices), about 17% of its market cap. It’s reasonable to expect they might intend to sell.

Solana’s fall has put stress on one of its leading decentralized finance applications, Solend, a money market that works much like Ethereum’s Compound. Solend is gradually unwinding a single, almost $30 million USDC (stablecoin) loan, collateralized by SOL, which is falling fast while the protocol tries to sell. Much like SOL’s price, the total value locked (TVL) in various DeFi projects on Solana has fallen much further in the last day than on other smart contract blockchains, according to DefiLlama. Solana TVL is down 45% over the last day, to $470 million, as of Wednesday afternoon, New York time.

TSMC Reportedly Looks To Raise a Second Arizona Chip Fab

An anonymous reader quotes a report from The Register: Taiwan’s chipmaking giant TSMC is said to be preparing to build another semiconductor fabrication plant in Arizona, alongside the facility it completed this summer, in a move that may be seen as a vindication of the US government’s CHIPS Act funding. According to reports in the Wall Street Journal, TSMC is planning to announce in the near future that it will build a further factory for making cutting edge chips at a site just north of Phoenix, adjacent to the $12 billion Fab 21 plant the company decided to construct in 2020.

The new facility will be used to manufacture 3nm chips, according to the paper, which cites anonymous sources “familiar with the expansion plans.” The scale of this project is expected to be comparable to the existing plant. Reports last year suggested that TSMC was already considering constructing up to five additional semiconductor factories in Arizona, on top of the one just completed, which is not scheduled to start up production of chips until 2024. The move to build another plant comes despite the Taiwanese chip behemoth announcing recently that it was cutting back on its capital investment budget in the face of a market slowdown which led to TSMC predicting that Q4 revenue growth will likely be flat. However, the fact that TSMC is still considering further facilities in Arizona could be seen as vindication that the US CHIPS Act, which includes subsidies and other incentives for semiconductor companies like TSMC to build on American soil, is having the desired effect.

‘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.
