California's Governor Proposes Extending the Life of Its Last Nuclear Plant (apnews.com) 176

"California Gov. Gavin Newsom on Friday proposed extending the life of the state's last operating nuclear power plant by five to 10 years," reports the Associated Press, "to maintain reliable power supplies in the climate change era." Newsom's draft proposal includes a potential forgivable loan for PG&E for up to $1.4 billion and would require state agencies to act quickly to clear the way for the reactors to continue running. The seaside plant located midway between Los Angeles and San Francisco produces 9% of the state's electricity. The proposal says its continued operation beyond 2025 is "critical to ensure statewide energy system reliability" as climate change stresses the energy system....

Newsom clearly wants to avoid a repeat of August 2020, when a record heat wave caused a surge in power use for air conditioning that overtaxed California's electrical grid. That caused two consecutive nights of rolling blackouts for the state, affecting hundreds of thousands of residential and business customers. The Newsom administration is pushing to expand clean energy, as the state aims to cut emissions by 40% below 1990 levels by 2030. Nuclear power doesn't produce carbon pollution like fossil fuels, but leaves behind waste that can remain dangerously radioactive for centuries.

The California Legislature has less than three weeks to determine if it will endorse the plan and attempt to extend the life of the plant — a decision that would be made amid looming questions over the costs and earthquake safety risks.... The Democratic governor, who is seen as a possible future White House candidate, has urged PG&E for months to pursue a longer run beyond a scheduled closing by 2025, warning that the plant's power is needed as the state transitions to solar, wind and other renewable sources of energy.

One concerned Democratic state Senator (from the district housing the plant) argued that another earthquake fault was discovered near the plant in 2008, and reminded the Associated Press that "seismic upgrades were never totally completed. Will they address that?"

China's Golden Era of Smartphones Is Ending (bloomberg.com) 44

The world's largest smartphone market is in deep trouble. China saw a 14.7% decline in phone shipments in the second quarter, according to research firm IDC. And multibillion-dollar pillars of the industry like Xiaomi Corp., Vivo and Oppo all reported steep sales declines. From a report: Many factors drove the fall, including a strict Covid Zero policy that torpedoed demand, but the bigger issue is one that's long been feared by the country's smartphone makers. China's 10-year-plus smartphone boom, fueled by new buyers and ceaseless upgrades, is likely coming to an end. China was eager to become a mobile nation a decade ago. It used state capital to build 4G base stations in almost every village, enabling brands like Oppo and Vivo to sell chic-looking devices to hundreds of millions of people in rural areas, most of whom had never tried a touchscreen. Apple, Samsung Electronics and Motorola pursued tech-savvy city dwellers with more expensive options. (Although the latter two quickly fell out of the game due to product flaws, marketing missteps and geopolitical pressures.)

More recently, smartphone makers saw an opportunity as China pushed toward advanced 5G networks. But few saw the trouble already brewing. A key problem is that China's massive smartphone market has become highly saturated. The country has more than 1.6 billion active mobile phone accounts by the end of last year compared to its 1.4 billion population. The penetration rate is well above the global average and has led to fierce competition. The need to replace phones has also dwindled. The life cycles of smartphones are getting longer, and can be stretched when the economy isn't doing well. The price of 5G service has prompted many people in China to simply keep their adequate 4G subscriptions.

Apple Might Remove the Headphone Jack From Its Next Entry-Level iPad 141

Apple's upcoming entry-level iPad is rumored to cut the 3.5mm headphone jack, joining the iPad Pro, iPad Air, iPad Mini, and the entire iPhone lineup. The Verge reports: MySmartPrice says the CAD renders are sourced from a case maker working on accessories for what will be the 10th-generation iPad. It's a substantial redesign from the classic iPad design that has been left largely untouched for years; Apple increased the display size slightly in 2017 and has made other internal hardware upgrades, but the overall look has remained consistent. It appears that's about to change, with the new iPad sharing the same flat-sides aesthetic as recent iPhones, iPads, the 14-inch / 16-inch MacBook Pro, and 2022 MacBook Air. Both 9to5Mac and MacRumors reported on the renders. But as always, treat these easily faked images with a healthy amount of skepticism.

The home button remains present, which means so do the sizable bezels above and below the display. MySmartPrice reports that the screen should be larger than the current 10.2-inch model, and there's a redesigned camera on the iPad's back reminiscent of the module from the iPhone X. The revamped iPad has a USB-C port, which would complete the transition for Apple's tablet line. These renders also include quad speakers, and that's where I get somewhat doubtful of what we're seeing: only the iPad Pro is currently outfitted with four speakers, so if this pans out, the base-level iPad would be leapfrogging both the iPad Air and Mini in the audio department. That strikes me as unlikely, but it could also serve as Apple's justification for nixing the headphone jack from a product used in many classrooms and other scenarios where support for affordable wired headphones has been meaningful.

Siemens' New Home EV Charger Adapter Ends Need For Electrical Panel Upgrades (electrek.co) 159

An anonymous reader quotes a report from Electrek: Siemens and Philadelphia-based ConnectDER have partnered to debut a groundbreaking simple home EV charger connector. Previously, homeowners who wanted to install EV chargers might have had to spend thousands of dollars to modify their home's electrical panel. This new proprietary plug-in adapter will eliminate that cost and allow installation and connection in minutes. ConnectDER makes meter collars that are installed between the home's meter and the meter socket to create a single plug-and-play access point for distributed energy resources (DER) installation. In other words, the collars easily add new electrical service capacity for things like solar and energy storage. Now ConnectDER will exclusively manufacture and supply a proprietary plug-in EV charger adapter to Siemens.

The new adapter will enable electric car owners to charge their EVs by connecting chargers directly through the meter socket, which is on every home. It provides more useable capacity by monitoring total load and controlling the EV circuit to ensure the total capacity rating is within the limit. Bypassing the electrical panel reduces the EV charger installation cost by around 60 to 80% because electrical panel upgrades aren't needed. [...] Nearly half of US home electrical panels previously would have needed upgrades to allow the installation of a typical Level 2 charger, usually a 7-11kW device requiring 40-60 Amps on a 240V line.
A Siemens spokesperson said that the company is still finalizing pricing, but "it will be a fraction of the cost of a service panel upgrade or other modifications often needed to make for a charger. Additionally, in some cases, the cost may be fully borne by utility programs."

The adapters themselves are expected to be available by first quarter 2023.

FCC Chair Proposes Raising Broadband Standard To 100Mbps (engadget.com) 76

Chairwoman Jessica Rosenworcel has proposed raising the minimum definition of broadband to 100Mbps for downloads and 20Mbps for uploads. Engadget reports: The previous 25/3 benchmark is both outdated and hides just how many low-income and rural internet users are being "left behind and left offline," Rosenworcel said. The chair said multiple pieces of evidence supported the hike, including requirements for new network construction stemming from the Infrastructure Investment and Jobs Act. The FCC had already proposed upgrades to rural speeds through a special program, but this would affect the definition of broadband regardless of where users live in the country.

Rosenworcel also wanted the minimum speed to evolve over time. She proposed setting a much higher standard of 1Gbps down and 500Mbps up for some point in the future. The leader further suggested more criteria for determining the "reasonable and timely" rollout of broadband, including adoption rates, affordability, availability and equitable access.

EU Lawmakers Slam 'Radical Proposal' To Let ISPs Demand New Fees From Websites (arstechnica.com) 42

An anonymous reader quotes a report from Ars Technica: Fifty-four members of the European Parliament (MEPs) are protesting what they call a "radical proposal" to require payments from online service providers to Internet service providers. Noting that Europe's 2015 "Open Internet Regulation ensures that citizens are free to use whichever apps and websites they wish," the MEPs said they have "deep concern about the European Commission's plans to change our net neutrality legislation in the upcoming Connectivity Infrastructure Act to be proposed in autumn, without having consulted the public, technology experts, academics, civil society, or expert regulatory agencies."

No specific proposal has been released, but "statements to the press indicate that a new provision would require payments from online service providers to broadband providers -- ostensibly to fund the rollout of 5G and fiber to the home," the MEPs wrote in the letter yesterday (PDF) to the European Commission. The letter cited a May 2 Reuters article that said, "Tech giants such as Google, Meta, and Netflix may have to bear some of the cost of Europe's telecoms network, Europe's digital chief Margrethe Vestager said on Monday, following EU telecoms operators' complaints." The MEPs' list of references also includes two Ars Technica articles from 2012 when a similar proposal was being discussed.

Vestager reportedly said at a news conference that "there are players who generate a lot of traffic that then enables their business but who have not been contributing actually to enable that traffic. They have not been contributing to enabling the investments in the rollout of connectivity... and we are in the process of getting a thorough understanding of how could that be enabled." [...] The MEPs' letter further argued that charging websites for access to broadband consumers would help ISPs abuse their monopolies: "Adopting a model that allows for or mandates access fees would be a disastrous return to the economic model for telephony, where telecommunications companies and countries leveraged their termination access monopolies to make communication expensive. Because phone companies had a monopoly over their customers, they could charge exorbitant prices to anyone seeking to call their customers. Broadband providers have the same monopoly over their customers. Allowing them to charge content providers for access could cause significant harm to the Internet economy." The MEPs also doubt such fees would improve broadband connectivity, saying that "factors such as permits or construction capacities can act as more severe barriers than lack of funding." They urged the European Commission to take its time and open an official consultation, saying, "There is no emergency that requires action in autumn 2022."

Global PC Shipments Down 15% in Q2 2022 Due To Chinese Production Crunch (canalys.com) 7

The second quarter of 2022 brought major disruption to the PC market, as COVID lockdowns in China stymied manufacturing. Research firm Canalys: The latest Canalys data shows total shipments of desktops and notebooks fell 15.0% annually to 70.2 million units, the lowest level since a similar disruption occurred in Q1 2020. Demand headwinds, especially from consumers, have also ramped up as inflation remains unchecked in many of the world's largest PC markets. Notebook shipments fell 18.6% in Q2 2022 at 54.5 million units, down for a third consecutive quarter as education procurement remained muted compared with the same quarter a year ago. Desktops fared much better, posting modest growth of 0.6% to 15.6 million units as the strength of commercial demand amid the further opening of economies helped spur investment in desktop refreshes and upgrades. The premium commercial segment will remain a bright spot for the overall PC market this year, despite mounting challenges in the global macroeconomic outlook.

Six Ground-Breaking New Linux Laptops Released in the Last Two Weeks (beehiiv.com) 84

In the last two weeks, six new Linux laptops have hit the market (or were announced). "The Linux hardware scene is getting better by the day," writes the site FOSS Weekly:
  • MNT Research introduces a "more affordable" 7-inch mini Linux laptop, the MNT Pocket Reform.
  • KDE's Slimbook 4 is here with AMD Ryzen 7 5700U processor and a better battery, starting from $1,000. "Buying from Slimbook supports KDE development too," notes Gaming on Linux, adding that there's a choice of 14 or 15.6 inch displays.
  • TUXEDO's Pulse 15 — Gen2 (also with an AMD Ryzen 7 5700U processor) has a 15-inch HiDPI WQHD 165Hz display, along with eight cores and 16 threads. (And the Register notes its twin cooling fans, "allowing them to overclock the chip and run it at 35W," and a choice of distros.)
  • Pre-orders have opened for the Roma — the first RISC-V Laptop (which may ship in September). Ars Technica reports they're offering "free Silicon upgrades" — that is free system-on-a-chip and system-on-module upgrades for its quad-core RISC-V CPU. And there's also a companion NPU/GPU, notes a blog post at RISCV.org, "for the fastest, seamless RISC-V native software development available." (As well as "early access to next-generation laptop and accessory upgrades at generous discounts or for free.") The blog post calls it a "Web3-friendly platform with NFT creation and publication plus integrated MetaMask-style wallet."

UK's National Grid Plans £54B Wind-Power Network Upgrade (bbc.com) 79

"There are now more than 11,000 wind turbines on and offshore, which produce nearly a quarter of the UK's electricity," reports the BBC.

But rather than rely on future windfarms to build their own connections to the grid, the country's national grid operator, National Grid ESO, plans to spend £54 billion ($64B) on its biggest network upgrade in 60 years: National Grid ESO, which runs the electricity network, said the plan it has laid out would enable the government to deliver 50GW of offshore wind power by 2030 — a third of the UK's electricity demand — while creating 168,000 jobs. It claimed the network could lead to more than £50bn of investments over the next eight years.... These network upgrades are deemed essential to accommodate and integrate a new raft of renewable energy projects also announced on Thursday. A total of 23 gigawatts (GW) of electricity — 24 million homes worth at current power usage — worth of contracts were awarded this morning to bidders wishing to build new renewable facilities.

The auction saw offshore wind prices hit a new record low at a quarter of the current cost of gas generated power.

The article notes 21,000 people signed a petition urging longer offshore networking instead. One advocacy group complains that building onshore power lines through regions like rural East Anglia is "short-sighted and shameful."

How the Large Hadron Collider Will Hunt for Dark Matter (msn.com) 64

It's the world's largest particle accelerator — and after a three-year pause for upgrades, CERN's Large Hadron Collider now detects more data, runs at higher speeds, and performs at its highest energy level ever — a whopping 13.6 trillion electron volts.

Will that prove the existence of dark matter? The Washington Post reports: Though scientists largely believe dark matter is real, none have been able to see or create it. Data collection and power upgrades made to the particle smasher could provide researchers one of their best chances to visualize and understand the substance.... Inside the collider, superconducting magnets are chilled to roughly minues-456 degrees Fahrenheit — colder than space — while two particle beams traveling close to the speed of light are made to collide. Using advanced sensors and monitors, scientists analyze the substances created by those collisions, which replicate conditions similar to the Big Bang. It allows them to learn about the earliest moments of the universe...

During the Large Hadron Collider's four-year experiment, scientists are hoping to find evidence of dark matter. As they fire up the machine, protons will spin at nearly the speed of light. The hope, researchers said, is that when they collide, it creates new particles resembling the properties of dark matter.... "High-energy colliders remain the most powerful microscope at our disposal to explore nature at the smallest scales and to discover the fundamental laws that govern the universe," said Gian Giudice, head of CERN's theory department....

If CERN scientists do not discover dark matter in the next four years, they have more upgrades in the works. The upgrades are likely to take three years after the current run stops, leaving the fourth round of data collection and experiments to start in 2029.

As planned, the trial could capture 10 times more data than previous experiments, according to CERN's website.

Europe Wants a High-Speed Rail Network To Replace Airplanes (cnn.com) 82

An anonymous reader quotes a report from CNN Travel: Breakfast in Paris, lunch in Frankfurt and dinner in Vienna -- all without the hassle and frustration of flying. Imagine a network of modern, super-fast and comfortable trains hurtling between every major city in the European Union, providing a reliable, comfortable and sustainable alternative to air travel. That was the vision outlined by rail industry leaders in Lyon, France, on June 29, amid ambitious European plans to double high-speed rail use by 2030 and triple current levels by 2050. Only a massive -- and accelerated -- expansion of the high-speed network can achieve these hugely ambitious targets, but are they a realistic and affordable proposition?

Unlike many parts of the world, Europe already has thousands of kilometers of dedicated high-speed railway. France's world-famous TGVs, Germany's ICE and Spain's AVE have transformed rail travel over the last 40 years, but they remain largely focused on domestic markets. That's no surprise. When countries are investing billions of euros in new infrastructure, political pressure to squeeze out the maximum benefit for taxpayers is inevitable. Building lines across international borders, even within the European Union, creates tension over who pays for what, how the contracts are allocated, conflicting national standards and regulations and a host of other obstacles. For decades it's been too easy to kick difficult projects down the road until they become someone else's problem.

Now a body of European organizations have committed to a new study highlighting the numerous benefits of an expanded high-speed rail network connecting national capitals and major cities. These include the European Commission, the Community of European Railways, the European Rail Supply Industry and ALLRAIL, which represents non-state-owned railways. Most importantly the group will investigate how to pay for tens of thousands of kilometers of new lines and how a radical transformation of the continent's rail network can help the EU deliver on its "Green Deal' objective of carbon neutrality by 2050. Some of that expansion will come on new routes that are planned or under construction but many more will be needed to facilitate the vision of European leaders.
"According to EU statistics, 17 of the 20 busiest air routes in Europe cover distances of less than 434 miles (700 kilometers) -- exactly the kind of distances where city center-to-city center trains can offer faster, cleaner and more sustainable journeys -- if the right infrastructure exists," adds CNN.

"And according to Alberto Mazzola of the Community of European Railways, carbon emissions trading could be a key tool in funding the massive investment required to complete a Europe-wide high-speed rail network." A Paris-Berlin flight generates at least six times the CO2 emissions of a similar train journey, notes the report. Meanwhile, flights of less than 621 miles between and within European countries are estimated to create 28 million metric tons of CO2 every year.

"Excess carbon emissions from airliners, trucks and cars are currently charged at 50 euros per ton in the EU, but this could soon rise to 80 euros per ton," reports CNN. "If just 10% of that revenue is re-invested in transport it could add around 8 billion euros a year to the pot for rail upgrades."

The Mars Express Spacecraft Is Finally Getting a Windows 98 Upgrade (theverge.com) 40

Engineers at the European Space Agency (ESA) are getting ready for a Windows 98 upgrade on an orbiter circling Mars. The Verge reports: The Mars Express spacecraft has been operating for more than 19 years, and the Mars Advanced Radar for Subsurface and Ionospheric Sounding (MARSIS) instrument onboard has been using software built using Windows 98. Thankfully for humanity and the Red Planet's sake, the ESA isn't upgrading its systems to Windows ME. The MARSIS instrument on ESA's Mars Express was key to the discovery of a huge underground aquifer of liquid water on the Red Planet in 2018. This major new software upgrade "will allow it to see beneath the surfaces of Mars and its moon Phobos in more detail than ever before," according to the ESA. The agency originally launched the Mars Express into space in 2003 as its first mission to the Red Planet, and it has spent nearly two decades exploring the planet's surface.

MARSIS uses low-frequency radio waves that bounce off the surface of Mars to search for water and study the Red Planet's atmosphere. The instrument's 130-foot antenna is capable of searching around three miles below the surface of Mars, and the software upgrades will enhance the signal reception and onboard data processing to improve the quality of data that's sent back to Earth. "We faced a number of challenges to improve the performance of MARSIS," explains Carlo Nenna, a software engineer at Enginium who is helping ESA with the upgrade. "Not least because the MARSIS software was originally designed over 20 years ago, using a development environment based on Microsoft Windows 98!"

Verizon, AT&T Agree to Delay Some 5G Rollouts Near Airports (apnews.com) 21

The Associated Press reports: Federal regulators say Verizon and AT&T will delay part of their 5G rollout near airports to give airlines more time to ensure that equipment on their planes is safe from interference from the wireless signals, but the airline industry is not happy about the deal. An airline industry trade group said federal regulators are taking a "rushed approach" to changing equipment on planes under pressure from the telecommunications companies.

The Federal Aviation Administration said Friday that the wireless companies agreed to delay some of their use of the C-Band section of the radio spectrum until July 2023. "We believe we have identified a path that will continue to enable aviation and 5G C-band wireless to safely co-exist," said the FAA's acting administrator, Billy Nolen. However, aviation groups say the C-Band service could interfere with radio altimeters — devices used to measure a plane's height above the ground....

Nolen said planes most susceptible to interference — smaller, so-called regional airline planes — must be retrofitted with filters or new altimeters by the end of this year. Components to retrofit larger planes used by major airlines should be available by July 2023, when the wireless companies expect to run 5G networks in urban areas "with minimal restrictions," he said. Airlines for America, a trade group for the largest U.S. carriers, said the FAA hasn't approved necessary upgrades and manufacturers have not yet produced the parts. "It is not at all clear that carriers can meet what appears to be an arbitrary deadline," trade group CEO Nicholas Calio said in a letter to Nolen....

Verizon said the agreement will let the company lift voluntary limits on its 5G rollout around airports "in a staged approach over the coming months." AT&T said it agreed to take "a more tailored approach" to controlling the strength of signals near runways so airlines have more time to retrofit equipment.

Apple Hit With Yet Another 'Batterygate' Lawsuit (zdnet.com) 62

An anonymous reader quotes a report from ZDNet: The memory of "Batterygate" continues to be a thorn in Apple's side. In case you need a reminder, "Batterygate" refers to a 2016/17 scandal where Apple added an undocumented battery throttling capabilities to iOS 10.2.1 designed to slow the performance of the iPhone if the battery was deemed to be worn. It also came with unexpected side effects, causing handsets to reboot in cold weather or when the battery's charge level was low. The feature was initially rolled out to iPhone 6, iPhone 6s, and iPhone SE and later expanded to include the iPhone 7, 7 Plus, 8, 8 Plus and iPhone X models.

This latest UK-based multimillion-pound legal claim has been launched by Justin Gutmann, a consumer rights campaigner, and alleges that Apple deliberately misled users, and rather than roll out a battery recall or replacement program; the company instead pushed out this feature to cover up the fact that older iPhone batteries were not able to cope with the new power demands put on them.

Apple did eventually roll out a $29 battery replacement program, a program that saw the company carry out 11 million battery replacements in 2018, compared to the 1 to 2 million that would normally be carried out in a year. This resulted in Apple issuing a profit warning in January 2019, the company's first since 2002. If Apple loses, the company could be forced to pay damages of more than $950m to the 25 million people who purchased affected iPhones. Following the US settlement in March 2020, Apple agreed to settle a class-action lawsuit over the same issue, paying out $25 per iPhone, with the total capped at $310m.
"We have never -- and would never -- do anything to intentionally shorten the life of any Apple product or degrade the user experience to drive customer upgrades," Apple said in a statement on Thursday. "Our goal has always been to create products that our customers love, and making iPhones last as long as possible is an important part of that."

Why Rural Americans Keep Waiting for Fast Internet, Despite Billions Spent (wsj.com) 169

The U.S. government has spent billions of dollars on several rounds of programs to upgrade internet speeds in rural areas over the past decade. Despite those efforts, many residents are still stuck with service that isn't fast enough to do video calls or stream movies -- speeds that most take for granted. From a report: Many communities have been targeted for broadband upgrades at least twice already, but flaws in the programs' design have left residents wanting. The Wall Street Journal analyzed 1.4 million largely rural census blocks that were included in a series of nationwide Federal Communications Commission broadband programs over the past decade. In the latest program, the Rural Digital Opportunity Fund, rolled out in 2020, internet service providers won rights to public funding in about 750,000 census blocks, covering every state except Alaska. The Journal's analysis found that more than half of those census blocks -- areas with a combined population of 5.3 million people -- had been fully or partially covered by at least one previous federal broadband program.

Most U.S. households today have access to internet download speeds of at least 100 megabits per second and upload speeds of 10 Mbps, according to government data. Although the FCC's programs have made progress, some rural Americans still can't get 4 Mbps download and 1 Mbps upload speeds -- the level of service that was the federal standard in 2011. The broadband saga around Heavener, Okla., illustrates some of the problems. Heavener, with a population of around 3,000, is surrounded by cattle pastures and forested hills. Today some buildings on the main streets have good broadband service, but the internet deteriorates outside town, residents say. Much of the area, in Le Flore County, was slated for upgrades under the Rural Digital Opportunity Fund in 2020 -- and some of those areas had already been part of prior programs.

Ten Years After the Higgs, Physicists Face the Nightmare of Finding Nothing Else (science.org) 90

A decade ago, particle physicists thrilled the world. On 4 July 2012, 6000 researchers working with the world's biggest atom smasher, the Large Hadron Collider (LHC) at the European particle physics laboratory, CERN, announced they had discovered the Higgs boson, a massive, fleeting particle key to their abstruse explanation of how other fundamental particles get their mass. The discovery fulfilled a 45-year-old prediction, completed a theory called the standard model, and thrust physicists into the spotlight. Then came a long hangover. From a report: Before the 27-kilometer-long ring-shaped LHC started to take data in 2010, physicists fretted that it might produce the Higgs and nothing else, leaving no clue to what lies beyond the standard model. So far, that nightmare scenario is coming true. "It's a bit disappointing," allows Barry Barish, a physicist at the California Institute of Technology. "I thought we would discover supersymmetry," the leading extension of the standard model.

It's too early to despair, many physicists say. After 3 years of upgrades, the LHC is now powering up for the third of five planned runs, and some new particle could emerge in the billions of proton-proton collisions it will produce every second. In fact, the LHC should run for another 16 years, and with further upgrades should collect 16 times as much data as it already has. All those data could reveal subtle signs of novel particles and phenomena. Still, some researchers say the writing is on the wall for collider physics. "If they don't find anything, this field is dead," says Juan Collar, a physicist at the University of Chicago who hunts dark matter in smaller experiments. John Ellis, a theorist at King's College London, says hopes of a sudden breakthrough have given way to the prospect of a long, uncertain grind toward discovery. "It's going to be like pulling teeth, not like teeth falling out."

As the Large Hadron Collider Revs Up, Physicists' Hopes Soar (nytimes.com) 124

The particle collider at CERN will soon restart. From a report: In April, scientists at the European Center for Nuclear Research, or CERN, outside Geneva, once again fired up their cosmic gun, the Large Hadron Collider. After a three-year shutdown for repairs and upgrades, the collider has resumed shooting protons -- the naked guts of hydrogen atoms -- around its 17-mile electromagnetic underground racetrack. In early July, the collider will begin crashing these particles together to create sparks of primordial energy. And so the great game of hunting for the secret of the universe is about to be on again, amid new developments and the refreshed hopes of particle physicists. Even before its renovation, the collider had been producing hints that nature could be hiding something spectacular. Mitesh Patel, a particle physicist at Imperial College London who conducts an experiment at CERN, described data from his previous runs as "the most exciting set of results I've seen in my professional lifetime."

A decade ago, CERN physicists made global headlines with the discovery of the Higgs boson, a long-sought particle, which imparts mass to all the other particles in the universe. What is left to find? Almost everything, optimistic physicists say. When the CERN collider was first turned on in 2010, the universe was up for grabs. The machine, the biggest and most powerful ever built, was designed to find the Higgs boson. That particle is the keystone of the Standard Model, a set of equations that explains everything scientists have been able to measure about the subatomic world. But there are deeper questions about the universe that the Standard Model does not explain: Where did the universe come from? Why is it made of matter rather than antimatter? What is the "dark matter" that suffuses the cosmos? How does the Higgs particle itself have mass? Physicists hoped that some answers would materialize in 2010 when the large collider was first turned on. Nothing showed up except the Higgs -- in particular, no new particle that might explain the nature of dark matter. Frustratingly, the Standard Model remained unshaken.

We're Still Waiting for the Laptop's Big Year (theverge.com) 34

An anonymous reader shares a report: After a long, long month of laptop releases, Computex 2022 is finally over. In some ways, it's the Computex that wasn't. The early part of this year was an exciting time to be a laptop reporter. Every company and its mother announced that big ideas were on the way. Wacky products abounded, from monitors to phones. LG Display (which supplied the 13.3-inch panel for Lenovo's ThinkPad X1 Fold) showed off a 17-inch foldable OLED screen. We saw RGB, OLEDs, and haptics galore. Chipmakers promised architectural innovations and performance gains. We were told that these were all coming soon.

At the end of May was Computex, the biggest laptop-specific show of the year. This would've been the perfect time for some of these innovative releases to be, you know, released -- or get a release date. But we didn't get them at Computex 2022. The show was, in fact, aggressively unexciting. We got a heck of a lot of chip bumps. We got some higher refresh rate displays. We got an HP Spectre x360 with rounder corners. Don't get me wrong: incremental upgrades, both to internal specs and external elements, are important. They will make a difference in people's lives. Companies do not need to reinvent the wheel with every single laptop they release. But it is still worth noting that a number of devices that truly seem poised to expand or redefine their categories are not yet here.

'The Cynic's Guide to Desktop Linux' (theregister.com) 181

The Register has unveiled their "cynic's guide to desktop Linux," which they ultimately concede is a snarky yet affectionate list of "the least bad distros."

For those who are "sick of Windows but can't afford a Mac," the article begins by addressing people who complain there's too many Linux distros to choose from. "We thought we'd simplify things for you by listing how and in which ways the different options suck." - The year of Linux on the desktop came and went, and nobody noticed — maybe because it doesn't say "Linux" on it. ChromeOS only runs on ChromeBooks and ChromeBoxes, but they outsold Macs for a while before the pandemic. "Flex" is the version for ordinary PCs... ChromeOS Flex works great, because it only does one thing: browse the web. You can't install apps, not even Android ones: only official kit does that. You can run Debian containers: if you know what that means, go run Debian. If you don't know what that means, trust us, you don't want to.

- Ubuntu is an ancient African word that means I can't configure Debian....

- Mint is an Ubuntu remix with knobs on. It was an also-ran for years, but when Ubuntu went all Mac-like it saw its chance and grabbed it — along with the number one spot in the charts. It dispenses with some of the questionable bits of recent Ubuntu, such as GNOME and Snaps, but replaces them with dodgy bits of its own, such as a confusing choice of not one, not two, but three Windows-like desktops, and overly cautious approaches to updates and upgrades.

- Debian is the daddy of free distros, and the one that invented the idea of a packaging tool that automatically installs dependencies. It's easier than it used to be, but mired in politics. It's sort of like Ubuntu, but more out of date, harder to install, and with fewer drivers. If that sounds just your sort of thing, go for it.

There's 10 snarky entries in all, zinging Fedora, openSUSE, Arch Linux, and Pop!_OS — as well as the various spinoffs of Red Hat Enterprise Linux. (The article calls Rocky Linux and AlmaLinux "RHEL with the serial numbers filed off.")

And there's also one final catch-call entry for "Tiny obscure distros. All of them."

Communication Reestablished with NASA's 'Ingenuity' Mars Helicopter (nasa.gov) 37

"We have reestablished reliable communications with Ingenuity," reported the team lead for NASA's Mars helicopter, Teddy Tzanetos, in a blog post last week. As detailed in our last blog post, for the first time in our yearlong extended mission we had a loss of communications with Ingenuity from the downlink of May 3 (Sol 427) and May 4 (Sol 428). After a week of anomaly investigation, two sols dedicated to data collection, and the heroic efforts of the Perseverance and Ingenuity operations teams, I am very happy to report that we have reestablished reliable communications with Ingenuity.

Based on all available telemetry, the helicopter appears healthy, and we have resumed a modified form of operations. Assuming winter recommissioning activities complete nominally, Ingenuity's 29th flight may occur in the next few sols.... All telemetry downlinked so far suggests that Ingenuity is healthy, with no signs of damage from the overnight cold cycles.

That's the good news.

The bad news? Telemetry from Ingenuity confirmed that the loss of communications was due to insufficient battery state-of-charge (SOC) going into the night, which resulted in a reset of our mission clock. This daily state-of-charge deficit is likely to persist for the duration of Martian winter (until September/October).

Challenges like these are to be expected: After hundreds of sols and dozens of flights beyond the five flights originally planned, the solar-powered helicopter is in uncharted terrain. We are now operating far outside our original design limits. Historically, Mars is very challenging for spacecraft (particularly solar-powered spacecraft). Each sol could be Ingenuity's last....

We have reached the point in Martian late fall/early winter at which Ingenuity can no longer support the energy demands of nominal operations. Starting on the evening of Sol 426, we believe Ingenuity started experiencing overnight battery brownouts (drops in the battery's voltage), which reset the electronics. Due to the seasonal decrease in available solar energy, increases in airborne dust density, and the drop in temperatures, the energy demand to keep the electronics powered and warm throughout the night has surpassed Ingenuity's available energy budget.... We expect to be in this challenging winter energy paradigm until around Sol 600, at which point we expect to return to being power-positive from sol to sol.

The blog post says NASA can cope with a resetting mission clock. But the helicopter's battery (and other electronics) are now facing overnight ambient temperatures of about minus 80 degrees C (minus 112 degrees F), "a lifetime risk to our electronic components." Although component failure has always been a risk that we have carried since rover deployment, that risk is now magnified... We do have limited electronics core module (ECM) component testing to suggest that select components may survive through the winter, but we cannot predict how the entire ECM will fare throughout winter. Cold-soaking electronics is believed to have caused the end of the Opportunity and Spirit Mars rover missions.

Given our elevated risk posture, our focus in the last several sols has been to prioritize data downlink from Ingenuity to the Helicopter Base Station (HBS). We have a handful of Heli-to-HBS transfer activities left before all unique data are copied from Ingenuity to the HBS. Specifically, we are copying flight performance logs, electronics logs, and high-resolution color images from the last eight flights that are still onboard Ingenuity.

After all critical logs are transferred, the team will proceed with a recommissioning phase during which we will reestablish Ingenuity's flight-readiness given our ongoing overnight cold-cycling. Like during the technology demonstration phase, we will perform a high-speed spin before proceeding to flight. Should Ingenuity receive a clean bill of health, we would be ready to execute a short sortie to the southwest in Flight 29. This flight will improve our radio link for approximately the next four to six months while Perseverance samples at the river delta.

In the meantime, the Ingenuity flight software team will be preparing a series of upgrades to enable advanced navigation features. These new capabilities will help Ingenuity ascend the river delta and continue its missions as a forward scout for Perseverance past winter.

Mashable notes that Ingenuity recently sent back new footage showing its April 8th flight — calling it Ingenuity's "farthest and fastest flight yet." Flying 33 feet above the surface of Mars on April 8, "it traveled 2,310 feet — a bit less than half a mile — at 12 mph." The whole record-breaking feat lasted a little over 2.5 minutes, but that's much longer than its first flight of 39 seconds in the spring of 2021. NASA increased the new video's speed fivefold, reducing its runtime to less than 35 seconds.
