Bitcoin Fails To Produce 1 Block For Over An Hour

It took more than an hour to mine a block of bitcoin (BTC) on Monday, leaving thousands of transactions stuck in an unconfirmed state. CoinDesk reports: According to on-chain data from several block explorers, the interval between the two latest blocks mined by Foundry USA and Luxor was 85 minutes. According to Mempool, over 13,000 transactions were pending before the latest block was mined.

Last week Bitcoin underwent a difficulty adjustment to ensure block confirmations kept taking place every 10 minutes. With mining difficulty surging to 35.6 trillion it becomes more expensive to mine bitcoin, which heaps pressure on a mining industry that is dealing with soaring energy prices and a crypto bear market. Tadge Dryja, founder of the Lightning Network, tweeted that an 85-minute interval between blocks can be expected to happen once every 34 days, not taking into account difficulty changes.

Today, Americans can buy cheaper hearing aids for mild-to-moderate hearing loss without a prescription from a range of common retailers, including Walgreens, CVS, and Walmart—finally making the critical health devices more affordable and accessible to the estimated 28.8 million adults who could benefit from them.

The US Food and Drug Administration estimates the change could lower the average cost of obtaining a hearing aid by as much as $3,000. As of today, Walgreens is selling an over-the-counter model similar to hearing aids that range from $2,000 to $8,000 per pair at specialty retailers for just $799 per pair on its shelves, the White House said Monday. Likewise, Walmart said that, as of today, it is selling over-the-counter hearing aids ranging from $199 to $999 per pair, which are comparable to prescription hearing aids priced at $4,400 to $5,500 per pair.

The move is years in the making. In 2017, Congress passed a bipartisan proposal directing the FDA to set rules for selling over-the-counter devices. But the rules were slow to come. In July 2021, President Biden signed an executive order spurring the FDA to produce the rules, which the agency finalized in August of this year.

Datacenter Fire Takes Out South Korea's Top Two Web Giants

South Korea’s two largest domestic internet companies, Naver and Kakao, have experienced significant service interruptions after the datacenter that hosts much of their infrastructure was shut down by a Sunday fire. The Register reports: The datacenter in question is operated by SK C&C, one of the many arms of South Korean conglomerate SK. SK C&C offers a range of cloud and tech infrastructure services, bills itself as a “total digital transformation partner” and operates three datacenters, in which it happily houses client systems. The one in Pangyo, just south of South Korea’s capital Seoul, was built in 2014, covers 66,942 square meters, and boasts what SK C&C describes as “Latest/eco-friendly technology”. And it caught fire on the weekend. The company has not said what cause the facility to catch fire, nor the extent of the blaze.

But many services from Kakao and Naver were unavailable for many hours at a time, starting from Saturday afternoon. Impact of the outages was wide. The tweet below is an example of one business’s reaction. Kakao has acknowledged the outage in a blog post that apologizes for the service interruption and slow restoration, and admits that disaster recovery efforts were delayed. The company has created an Emergency Response Committee and three sub-committees — one to probe the cause of the incident, another to develop disaster countermeasures, and a third to arrange compensation for stakeholders. Naver’s announcement admits that “some functions such as search, news, shopping, cafe, blog, open talk, and smart store center had errors.” The company says all services have now been restored.

Skyports Opens Tokyo Office

Akihabara News (Tokyo) — UK-based Skyports, a firm aiming to become a leader in the vertiport industry, has announced the opening of a Tokyo office.

This follows the announcement last month of the appointment of Atsushi Okada, who has a background in urban design and smart city development, as the firm’s Japan country manager.

Yun-Yuan Tay, the Asia-Pacific head for Skyports, stated, “The Asia-Pacific region is an important hub for advanced air mobility, and Japan a leading market within it. With support from our investor Kanematsu Corporation, we have significantly matured our networks and portfolio in the country in the last year with multiple projects in progress. The incorporation of our Japanese office was the next logical step in strengthening our operations in the country.”

New Tokyo head Okada added that “Japan will play an important role in the future of advanced air mibility–the next big innovation for the transport and logistics sector. For Skyports, the focus for the next year is to progress our ongoing projects in Osaka and Tokyo through site assessments and regular engagements with the regulatory authorities as we look towards 2025 for initial deployment.”

The partnership between Skyports and the Tokyo-based Kanematsu Corporation has been deepening for several years. The two firms began their collaboration in 2020, and since then their links have become increasingly intimate.

In August, it was announced that Kanematsu, together with the Sumitomo Corporation, were leaders in Skyports’ US$26 million Series B investment round.

Aside from Japan, this business alliance is also quite active in the Singapore market, where drone delivery operations are being jointly developed. This is also where Skyports’ Asia-Pacific head office is located.

What it takes to re-create Rings of Power title sequence with Chladni figures

Steve Mould re-created The Rings of Power title sequence using patterns produced by vibrating square plates.

The first time I saw the opening credits for The Lord of the Rings: The Rings of Power, I thought the patterns looked remarkably like so-called “Chladni figures“: vibrational patterns that form when one scatters sand on a vibrating plate. It seems I was not the only one. British science communicator and YouTube star Steve Mould got so many comments from viewers about the similarities that he decided to test that hypothesis—by re-creating the title sequence with his own vibration-generated patterns. He documents the journey, and the associated science, in the video above. The final re-created title sequence starts at the 10:55 mark.

The phenomenon is technically known as cymatics. In 1680, Robert Hooke experimented with running a bow along glass plates covered in flour to induce vibrations and noted the telltale nodal patterns that formed in the flour.  “A rigid plate will have a set of natural resonance frequencies just like a string, and when the plate is excited at one of these frequencies, it will form a standing wave with fixed nodes,” University of North Carolina physicist Greg Gbur wrote back in 2013.  “These nodes will form lines on the plate, in contrast to points on the string.” The flour on the plate made those nodal lines visible.

The 18th century German physicist and musician Ernest Chladni perfected the method 100 years later when he repeated Hooke’s pioneering experiments with circular plates, even demonstrating the effect before Napoleon. The various shapes or patterns created by resonance frequencies are known as “Chladni figures” in his honor. Chladni even came up with a mathematical formula to predict which patterns would form. The higher the rate of oscillation, the more complex those figures will be. Similar methods are still used when designing acoustic instruments: violins, guitars, and cellos, for example.

Coinbase users scammed out of $21M in crypto sue company for negligence

Coinbase users scammed out of $21M in crypto sue company for negligence

Last fall, scammers infiltrated social platforms like dating apps, WhatsApp, Facebook, and Twitter, attempting to convince people to download Coinbase Wallet. Once the targeted users downloaded the wallet, the scammer would then send links to fraudulent websites, prompting users to purchase a “voucher” that seemed like a safe transaction protected and facilitated by Coinbase’s trusted platform, but was “actually a malicious smart contract.” Horrified users eventually discovered the smart contract gave “the scammers complete access to the entire funds in the victim’s wallets” without requiring authorizations to withdraw funds.

Today, nearly 100 people from all over the globe are seeking to make the publicly traded Coinbase pay for allegedly doing nothing to protect users. Users alleged that Coinbase was unmoved by reports that scammers were draining accounts of tens or hundreds of thousands of dollars’ worth of cryptocurrency. In total, Coinbase Wallet users that are suing collectively lost $21 million.

For months, users allegedly warned the company of this seeming security flaw. Instead of acting to protect users, though, Coinbase “took no remedial steps to fix the security flaw or even warn customers about this major problem, despite warning customers about other security risks,” according to a recently filed arbitration demand. This allegedly allowed “hundreds” of additional users to become targets of “an easily preventable” liquidity mining pool scam.

Nvidia’s last-minute 12GB RTX 4080 rebrand will be a pain for GPU makers

Nvidia’s last-minute 12GB RTX 4080 rebrand will be a pain for GPU makers

Enlarge (credit: Getty Images)

Late last Friday, Nvidia decided that it was “unlaunching” the lower-end 12GB version of its upcoming GeForce RTX 4080 graphics card so that it could be renamed and released at a later date. This was good news, for the people who care about this kind of thing—the $899 12GB RTX 4080 and $1,199 16GB RTX 4080 were substantially different cards with much different performance levels. Giving them both the same name could have created unnecessary disappointment and confusion for buyers of the cheaper card.

The problem for GPU makers is that Nvidia planned to launch those cards in mid-November, and partners had already started manufacturing and packaging them so they could be shipped out to retailers. Gamers Nexus has spoken with sources at two of Nvidia’s board partners about some of these logistical hurdles, reporting that existing boxes for 12GB RTX 4080 cards were being “collected and destroyed” and that Nvidia “is at least subsidizing the boxes, or part of them, to be replaced.” The relabeled GPUs will supposedly be reintroduced or relaunched (or un-unlaunched?) around CES in January 2023.

There will be costs for other board partners, too, both for GPUs that have already been produced and those that will be manufactured after Nvidia has settled on a name (Gamers Nexus says this hasn’t happened, but that “4070” or “4070 Ti” seems most likely). GPU coolers usually have the card’s name and model number printed on it somewhere, occasionally in a prominent place with programmable LEDs underneath. These coolers will either need to be rebadged, reprinted, or replaced to switch out the old RTX 4080 branding with the new branding.

Ultra-Processed Meals Are Unhealthier Than You Think

For a long time it has been known that diets dominated by ultra-processed food (UPF) are more likely to lead to obesity. But recent research suggests that high UPF consumption also increases the risk of cardiovascular disease, dementia and, according to a recent American study involving 50,000 health professionals, of developing colon cancer. From a report: On a more general note, last month a study in Nature Reviews Clinical Oncology found that people born after 1990 are more likely to develop cancer before they’re 50 than people born before 1970. It’s suspected that UPF might be a contributing factor to this development.

As the UK is estimated to draw more than 50% of its calorie intake from UPF, this is no passing health scare but an issue that goes to the very heart of our culinary lifestyle. But before looking deeper into the issue there is an obvious question: what is a UPF? NOVA (not an acronym) is a widely used food classification system that separates foods into four categories based upon their level of processing. Almost all foods, aside from fresh fruit and raw vegetables, undergo some degree of process. Cooking is a process, and it usually involves added ingredients such as oil and salt. In NOVA’s first category, Group 1 is unprocessed or minimally processed foods (fruit, vegetables, meat, eggs, milk). Group 2 is made up of processed culinary ingredients such as sugars, oils and butter. Group 3 is processed foods (canned vegetables and fish, bread, jam). Group 4 is ultra-high processed foods, which are mostly low in protein and fibre, and high in salt, sugar and fat, and have undergone industrial interventions such as extrusion, moulding and milling.
