OpenBSD 7.0 Released (openbsd.org) 12

Posted by EditorDavid from the older-than-Slashdot dept.
Long-time Slashdot reader ArchieBunker writes: Everyone's favorite security focused operating system OpenBSD released version 7.0 Thursday. In addition to the usual bug fixes and performance enhancements, support for RISC-V processors has been added.
It's 26 years old, and still chugging along. One interesting feature highlighted by Phoronix: Improving the ARM64 platform support with improved drivers for the Apple Silicon / Apple M1 but still not considered ready yet for end-users. OpenBSD 7.0 improvements on the Apple M1 include support for installing on a disk with a GPT and various Apple driver improvements for USB, GPIO, SPMI, NVMe storage, and other Apple M1 hardware components.

Pine64 Announces Updated PinePhone Pro Linux Powered Cellphone (tomshardware.com) 30

Posted by BeauHD from the what-more-do-you-need dept.
Pine64 today announced its latest Linux-powered device, the PinePhone Pro, an update to the original PinePhone which sees a more powerful device running mainline Linux (Manjaro in this case) on a mobile device that works as a cellphone and a desktop computer. Tom's Hardware reports: This combination of hardware and software makes the still slightly futuristic idea of confluence between mobile and desktop devices seem a step closer. Carry it around with you, and it's a phone. Plug it into a monitor, and it's a desktop PC. The KDE Plasma Mobile front-end adapts to the circumstances. Inside, it's much like any other phone, with a Rockchip RK3399S six-core SoC operating at 1.5GHz, 4GB of dual-channel LPDDR4 RAM, and 128GB of internal eMMC flash storage. It features a 13MP main camera sensor and a 5MP front-facing camera. There's a Micro-SD slot for expanded storage, and a six-inch 1440 x 720 IPS touchscreen. The PinePhone Pro is not a typical cell phone, rather the concept of convergence, the ability to use your phone as a computer is intriguing. Plug your PinePhone Pro into an external display and use it as a low-power desktop computer is something that has been attempted by a number of companies, including Canonical's attempt with Ubuntu Edge.

PinePhone Pro offers something that is missing from the majority of phones, privacy. A series of hardware DIP-switches, hidden under a rear cover, cut off access to the cameras, microphone, Wi-Fi 5 and Bluetooth 4.1 chips, headphone jack, and LTE modem (including GPS) should you ever need to. The layout and Pogo Pins of the new phone are identical to the original PinePhone, so all existing accessories should work. Retailing at $399, the PinePhone Pro's makers are realistic about the challenges of putting desktop Linux on a mobile device, especially in an ecosystem dominated by iOS and Android.

Modular Framework Laptop Gets Marketplace For All Those Modules (theverge.com) 38

Posted by BeauHD from the DIY-friendly dept.
Framework, makers of the modular 13.5-inch Framework laptop that's designed to be easily repaired and upgraded, has launched a dedicated marketplace filled with replacement parts and upgrades for its portable computer. The Verge reports: Writing in a blog post, the company said the marketplace is currently focused on replacement parts and expansion cards, but that it hopes to add more customization modules like additional language keyboards later this year, as well as third-party and community developed modules in 2022.

The marketplace already includes a range of expansion cards for the laptop, which are designed to slot into its four modular compartments to add everything from extra storage to features like MicroSD card slots or more USB ports. There's also user upgradeable RAM and storage for sale. But the store is clearly a work in progress, and lists a host of other items like replacement CPU-equipped mainboards, keyboards, and spare parts like batteries and displays as "coming soon."

Solar Panels On Half the World's Roofs Would Power the Planet (thedailybeast.com) 287

Posted by BeauHD from the but-it's-not-going-to-be-cheap dept.
An anonymous reader quotes a report from The Conversation: Our new paper in Nature Communications presents a global assessment of how many rooftop solar panels we'd need to generate enough renewable energy for the whole world -- and where we'd need to put them. Our study is the first to provide such a detailed map of global rooftop solar potential, assessing rooftop area and sunlight cover at scales all the way from cities to continents. We found that we would only need 50 percent of the world's rooftops to be covered with solar panels in order to deliver enough electricity to meet the world's yearly needs.

We designed a program that incorporated data from over 300 million buildings and analyzed 130 million km of land -- almost the entire land surface area of the planet. This estimated how much energy could be produced from the 0.2 million km of rooftops present on that land, an area roughly the same size as the U.K. We then calculated electricity generation potentials from these rooftops by looking at their location. Generally, rooftops located in higher latitudes such as in northern Europe or Canada can vary by as much as 40% in their generation potential across the year, due to big differences in sunshine between winter and summer. Rooftops near the equator, however, usually only vary in generation potential by around 1% across the seasons, as sunshine is much more consistent. This is important because these large variations in monthly potential can have a significant impact on the reliability of solar-powered electricity in that region. That means places where sunlight is more irregular require energy storage solutions -- increasing electricity costs. Our results highlighted three potential hotspots for rooftop solar energy generation: Asia, Europe and North America.

Of these, Asia looks like the cheapest location to install panels, where -- in countries like India and China -- one kilowatt hour (kWh) of electricity, or approximately 48 hours of using your laptop, can be produced for just 0.05p. This is thanks to cheap panel manufacturing costs, as well as sunnier climates. Meanwhile, the costliest countries for implementing rooftop solar are the U.S., Japan and the U.K. Europe holds the middle ground, with average costs across the continent of around 0.096p per kWh. The report mentions this endeavor would be "extremely expensive," and won't be a solution for some industries that require very large currents and specialized electricity delivery. However, the report concludes by saying: "If the costs of solar power continue to decrease, rooftop panels could be one of the best tools yet to decarbonize our electricity supply."

The Ship That Became a Bomb (newyorker.com) 67

Posted by msmash from the closer-look dept.
Stranded in Yemen's war zone, a decaying supertanker has more than a million barrels of oil aboard. If -- or when -- it explodes or sinks, thousands may die. From a report: Soon, a vast, decrepit oil tanker in the Red Sea will likely sink, catch fire, or explode. The vessel, the F.S.O. Safer -- pronounced "Saffer" -- is named for a patch of desert near the city of Marib, in central Yemen, where the country's first reserves of crude oil were discovered. In 1987, the Safer was redesigned as a floating storage-and-off-loading facility, or F.S.O., becoming the terminus of a pipeline that began at the Marib oil fields and proceeded westward, across mountains and five miles of seafloor. The ship has been moored there ever since, and recently it has degraded to the verge of collapse. More than a million barrels of oil are currently stored in its tanks. The Exxon Valdez spilled about a quarter of that volume when it ran aground in Alaska, in 1989.

The Safer's problems are manifold and intertwined. It is forty-five years old -- ancient for an oil tanker. Its age would not matter so much were it being maintained properly, but it is not. In 2014, members of one of Yemen's powerful clans, the Houthis, launched a successful coup, presaging a brutal conflict that continues to this day. Before the war, the Yemeni state-run firm that owns the ship -- the Safer Exploration & Production Operations Company, or sepoc -- spent some twenty million dollars a year taking care of the vessel. Now the company can afford to make only the most rudimentary emergency repairs. More than fifty people worked on the Safer before the war; seven remain. This skeleton crew, which operates with scant provisions and no air-conditioning or ventilation below deck -- interior temperatures on the ship frequently surpass a hundred and twenty degrees -- is monitored by soldiers from the Houthi militia, which now occupies the territory where the Safer is situated. The Houthi leadership has obstructed efforts by foreign entities to inspect the ship or to siphon its oil. The risk of a disaster increases every day.

A vessel without power is known as a dead ship. The Safer died in 2017, when its steam boilers ran out of fuel. A boiler is a tanker's heart, because it generates the power and the steam needed to run vital systems. Two diesel generators on deck now provide electricity for basic needs, such as laptop charging. But crucial processes driven by the boiler system have ceased -- most notably, "inerting," in which inert gases are pumped into the tanks where the crude is stored, to neutralize flammable hydrocarbons that rise off the oil. Before inerting became a commonplace safety measure, in the nineteen-seventies, tankers blew up surprisingly often, and with lethal consequences: in December, 1969, three of them exploded within seventeen days, killing four men. Since the boilers on the Safer stopped working, the ship has been a tinderbox, vulnerable to a static-electric spark, a discharged weapon, a tossed cigarette butt. [...] The Safer is not sinking. It is not on fire. It has not exploded. It is not leaking oil. Yet the crew of the ship, and every informed observer, expects disaster to occur soon. But how soon? A year? Six months? Two weeks? Tomorrow? In May, Ahmed Kulaib, the former executive at sepoc, told me that "it could be after five minutes."

Cloudflare Doesn't Have To Cut Off Copyright-Infringing Websites, Judge Rules (arstechnica.com) 21

Posted by BeauHD from the off-the-hook dept.
An anonymous reader writes: Cloudflare is not liable for the copyright infringement of websites that use its content-delivery and security services, a federal judge ruled yesterday. Cloudflare was sued in November 2018 by Mon Cheri Bridals and Maggie Sottero Designs, two wedding dress manufacturers and sellers that alleged Cloudflare was guilty of contributory copyright infringement because it didn't terminate services for websites that infringed on the dressmakers' copyrighted designs. The companies sought a jury trial, but Judge Vince Chhabria yesterday granted Cloudflare's motion for summary judgment in a ruling (PDF) in US District Court for the Northern District of California. Chhabria noted that the dressmakers have been harmed "by the proliferation of counterfeit retailers that sell knock-off dresses using the plaintiffs' copyrighted images," and that they have "gone after the infringers in a range of actions, but to no avail -- every time a website is successfully shut down, a new one takes its place." [...] While the ruling resolves the lawsuit's central question in Cloudflare's favor, the judge scheduled a case management conference for October 27 "to discuss what's left of the case."

A defendant is liable for contributory copyright infringement if it has knowledge of another's infringement and materially contributes to or induces that infringement, the judge noted in his ruling against the dressmakers. "Simply providing services to a copyright infringer does not qualify as a 'material contribution,'" he wrote. "Rather, liability in the Internet context follows where a party 'facilitate[s] access' to infringing websites in such a way that 'significantly magnif[ies]' the underlying infringement." Although a defendant can be found to materially contribute to copyright infringement if it acts as "an essential step in the infringement process," this should not be interpreted too broadly, the judge wrote. "As the Ninth Circuit has recognized, the language used in these tests is 'quite broad' and could encompass much innocuous activity if considered out of context. An analysis of contributory copyright infringement must therefore be cognizant of the facts in the key cases in which liability has been found," Chhabria wrote.

Mon Cheri Bridals and Maggie Sottero Designs alleged that Cloudflare contributes to copyright infringement by providing performance-improvement services, including its content-distribution network and caching capabilities that improve the quality of webpages and make them load faster, Chhabria wrote. But the "plaintiffs have not presented evidence from which a jury could conclude that Cloudflare's performance-improvement services materially contribute to copyright infringement. The plaintiffs' only evidence of the effects of these services is promotional material from Cloudflare's website touting the benefits of its services. These general statements do not speak to the effects of Cloudflare on the direct infringement at issue here." The plaintiffs did not prove that the faster website-load times enabled by Cloudflare "would be likely to lead to significantly more infringement." Additionally, Cloudflare removing infringing material from its cache would not prevent users from seeing the copyrighted images. "[R]emoving material from a cache without removing it from the hosting server would not prevent the direct infringement from occurring," Chhabria wrote.

Scientists Have Successfully Recorded Data To DNA In a Few Short Minutes (interestingengineering.com) 29

Posted by BeauHD from the breakthrough-development dept.
Researchers at Northwestern University have devised a new method for recording information to DNA that takes minutes rather than hours or days. Interesting Engineering reports: The researchers utilized a novel enzymatic system to synthesize DNA that records rapidly changing environmental signals straight into its sequences, and this method could revolutionize how scientists examine and record neurons inside the brain. To record intracellular molecular and digital data to DNA, scientists currently rely on multipart processes that combine new information with existing DNA sequences. This means that, for an accurate recording, they must stimulate and repress the expression of specific proteins, which can take over 10 hours to complete.

The new study's researchers hypothesized they could make this process faster by utilizing a new method they call "Time-sensitive Untemplated Recording using Tdt for Local Environmental Signals," or TURTLES. This way, they would synthesize completely new DNA rather than copying a template of it. The method enabled the data to be recorded into the genetic code in a matter of minutes. "Nature is good at copying DNA, but we really wanted to be able to write DNA from scratch," Northwestern engineering professor Keith E.J. Tyo, the paper's senior author, said, in the press release. "The ex vivo (outside the body) way to do this involves a slow, chemical synthesis. Our method is much cheaper to write information because the enzyme that synthesizes the DNA can be directly manipulated. State-of-the-art intracellular recordings are even slower because they require the mechanical steps of protein expression in response to signals, as opposed to our enzymes which are all expressed ahead of time and can continuously store information."

Oculus Quest Becomes a Paperweight When Facebook Goes Down (vrfocus.com) 79

Posted by BeauHD from the dependent-on-the-mothership dept.
When Facebook went down yesterday for nearly six hours, so did Oculus' services. Since Facebook owns VR headset maker Oculus, and controversially requires Oculus Quest users to log in with a Facebook account, many Quest owners reported not being able to load their Oculus libraries. "[A]nd those who just took a Quest 2 out of the box have reported that they're unable to complete the initial setup," adds PCGamer. As VRFocus points out, "the issue has raised another important question relating to Oculus' services being so closely linked with a Facebook account, your Oculus Quest/Quest 2 is essentially bricked until services resume." From the report: This vividly highlights the problem with having to connect to Facebook's services to gain access to apps -- the WiFi connection was fine. Even all the ones downloaded and taking up actual storage space didn't show up. It's why some VR fans began boycotting the company when it made all mandatory that all Oculus Quest 2's had to be affiliated with a Facebook account. If you want to unlink your Facebook account from Oculus Quest and don't want to pay extra for that ability, you're in luck thanks to a sideloadable tool called "Oculess." From an UploadVR article published earlier today: You still need a Facebook account to set up the device in the first place and you need to give Facebook a phone number or card details to sideload, but after that you could use Oculess to forgo Facebook entirely -- just remember to never factory reset. The catch is you'll lose access to Oculus Store apps because the entitlement check used upon launching them will no longer function. System apps like Oculus TV and Browser will also no longer launch, and casting won't work. You can still sideload hundreds of apps from SideQuest though, and if you want to keep browsing the web in VR you can sideload Firefox Reality. You can still use Oculus Link to play PC VR content, but only if you stay signed into Facebook on the Oculus PC app. Virtual Desktop won't work because it's a store app, but you can sideload free alternatives such as ALVR.

To use Oculess, just download it from GitHub and sideload it using SideQuest or Oculus Developer Hub, then launch it from inside VR. If your Quest isn't already in developer mode or you don't know how to sideload you can follow our guide here.

Researcher Refuses Telegram's Bounty Award, Discloses Auto-Delete Bug (arstechnica.com) 6

Posted by BeauHD from the ghost(ed)-reportings dept.
An anonymous reader quotes a report from Ars Technica: Telegram patched another image self-destruction bug in its app earlier this year. This flaw was a different issue from the one reported in 2019. But the researcher who reported the bug isn't pleased with Telegram's months-long turnaround time -- and an offered $1,159 bounty award in exchange for his silence. In February 2021, Telegram introduced a set of such auto-deletion features in its 2.6 release: Set messages to auto-delete for everyone 24 hours or 7 days after sending; Control auto-delete settings in any of your chats, as well as in groups and channels where you are an admin; and To enable auto-delete, right-click on the chat in the chat list > Clear History > Enable Auto-Delete. But in a few days, mononymous researcher Dmitrii discovered a concerning flaw in how the Telegram Android app had implemented self-destruction.

Messages that should be auto-deleted from participants in private and private group chats were only 'deleted' visually [in the messaging window], but in reality, picture messages remained on the device [in] the cache," the researcher wrote in a roughly translated blog post published last week. Tracked as CVE-2021-41861, the flaw is rather simple. In the Telegram Android app versions 7.5.0 to 7.8.0, self-destructed images remain on the device in the /Storage/Emulated/0/Telegram/Telegram Image directory after approximately two to four uses of the self-destruct feature. But the UI appears to indicate to the user that the media was properly destroyed.

But for a simple bug like this, it wasn't easy to get Telegram's attention, Dmitrii explained. The researcher contacted Telegram in early March. And after a series of emails and text correspondence between the researcher and Telegram spanning months, the company reached out to Dmitrii in September, finally confirming the existence of the bug and collaborating with the researcher during beta testing. For his efforts, Dmitrii was offered a $1,159 bug bounty reward. Since then, the researcher claims he has been ghosted by Telegram, which has given no response and no reward. "I have not received the promised reward from Telegram in [$1,159] or any other," he wrote.

Fairphone's Latest Sustainable Smartphone Comes With a Five-Year Warranty (theverge.com) 65

Posted by BeauHD from the reuse-and-recycle dept.
New submitter thegreatnick writes: The next generation of Fairphone -- an attempt to make an ethical smartphone -- has been announced with the Fairphone 4. The base specs include a Qualcomm Snapdragon 750G SoC, 6GB of RAM, and 128GB of storage (upgradeable to 8GB and 256GB). On the front, you'll get a 6.3-inch, 2340x1080 LCD display with slimmer bezels (compared to the Fairphone 3 design) and a teardrop notch for the 25-megapixel front camera. The 3,905mAh battery is Qualcomm Quick Charge 4.1 compatible, so if you have a compatible USB-C charger (not included in the box to reduce waste) you can take the battery from 0-50% in 30 minutes. The phone ships with Android 11 and has a side-mounted fingerprint reader in the power button, a MicroSD slot, and the option for dual-SIM usage via one physical nanoSIM and an eSIM.

Continuing Fairphone's progress in making a "fair" supply chain -- both ethically-clean raw materials and paying workers a fair wage -- it also describes the 4 as "e-waste neutral." This is a neat way of summing up the idea that the company will recycle one device for every Fairphone 4 it sells. In addition, Fairphone can boast that it now uses 70% "fair" materials inside the handset, including FairTrade Gold and Silver, aluminum from ASI-certified vendors, and a backplate made from 100% post-consumer recycled polycarbonate. In an upgrade to previous models, the Fairphone 4 has dual cameras, though it loses the headphone jack. The company says this was to achieve an IP54 waterproof rating (light splashes) -- a first for the Fairphone brand. It's also been announced that it will come with an industry-leading 5-year warranty and aims to get 6 years of software updates for the phone.

Cloudflare To Enter Infrastructure Services Market With New R2 Storage Product (techcrunch.com) 19

Posted by msmash from the let-them-fight dept.
Cloudflare, which has a network of data centers in 250 locations around the world, announced its first dalliance with infrastructure services today, an upcoming cloud storage offering called R2. From a report: Company co-founder and CEO Matthew Prince says that the idea for moving into storage as a service came from the same place as other ideas the company has turned into products. It was something they needed in-house and that led to them building it for themselves, before offering it to customers too. "When we build products, the reason that we end up building them is usually because we need them ourselves," Prince told me. He said that the storage component grew out of the need to store object components like images on the company's network. Once they built it, and they looked around at the cloud storage landscape, they decided that it would make sense to offer it as a product to customers too. [...] The R2 name is a little swipe at Amazon's S3 storage product and obviously a play on the name. The difference, according to Prince, is that they have found a way to reduce storage costs by up to 10% by eliminating egress fees. Cloudflare plans to price storage at $0.015 per GB of data stored per month. That compares with S3 pricing that starts at $0.023 per GB for the first 50 TB per month. Ben Thompson, writing at Stratechery: The reason that Cloudflare can pull this off is the same reason why S3's margins are so extraordinary: bandwidth is a fixed cost, not a marginal one. To take the most simplified example possible, if I were to have two computers connected by a cable, the cost of bandwidth is however much I paid for the cable; once connected I can transmit as much data I would like for free -- in either direction.

That's not quite right, of course: I am constrained by the capacity of the cable; to support more data transfer I would have to install a higher capacity cable, or more of them. What, though, if I already had built a worldwide network of cables for my initial core business of protecting websites from distributed denial-of-service attacks and offering a content delivery network, the value of which was such that ISPs everywhere gave me space in their facilities to place my servers? Well, then I would have massive amounts of bandwidth already in place, the use of which has zero marginal costs, and oh-by-the-way locations close to end users to stick a whole bunch of hard drives.

In other words, I would be Cloudflare: I would charge marginal rates for my actual marginal costs (storage, and some as-yet-undetermined-but-promised-to-be-lower-than-S3 rate for operations), and give away my zero marginal cost product for free. S3's margin is R2's opportunity.

Natural-gas Prices Are Spiking Around the World (economist.com) 135

Posted by msmash from the closer-look dept.
Across the world, a natural-gas shortage is starting to bite. Prices of power in Germany and France have soared by around 40% in the past two weeks. In many countries, including Britain and Spain, governments are rushing through emergency measures to protect consumers. Economist: Factories are being temporarily switched off, from aluminium smelters in Mexico to fertiliser plants in Britain. Markets are frantic. One trader says it is like the global financial crisis for commodities. Even in America, the world's biggest natural-gas producer, lobby groups are calling on the government to limit exports of liquefied natural gas (LNG), the price of which has climbed to $25 per million British thermal units (mBTU), up by two-thirds in the past month. In one sense the crisis has fiendishly complex causes, with a mosaic of factors from geopolitics to precautionary hoarding in Asia sending prices higher. Viewed from a different perspective, however, its causes are simple: an energy market with only thin safety buffers has become acutely sensitive to disruptions. And subdued investment in fossil fuels may mean higher volatility is here to stay.

The shortfall has taken almost everyone by surprise. In 2019 there was plenty of gas on the international market, thanks to new LNG plants coming online in America (see chart). When the covid pandemic struck and lockdown constrained demand, much of the excess gas went into storage in Europe. That came in handy last winter, which was particularly cold in northern Asia and Europe. The freeze pushed up demand for heating. In Asia gas prices quadrupled in three months. Buyers, such as national gas companies, looked to the LNG market to fill out supply. Many Europe-destined cargoes were diverted to Asia. Europe, by contrast, drew down on its reserves. Prices there only inched up. This year odd weather has featured again. A hot summer has added to booming gas demand in Asia. The region accounts for almost three-quarters of global LNG imports, according to AllianceBernstein, a financial firm.

Ring Puts An Eero Router Inside Its New Home Alarm System (engadget.com) 28

Posted by BeauHD from the two-in-one dept.
Eero and Ring -- two Amazon-owned companies -- have teamed up to produce a home security system that incorporates an Eero router inside. Engadget reports: Ring COO Mike Harris said that the decision to work with Eero was not one foisted down from upon high by Amazon. Instead, Harris said that both companies saw the opportunity to work together to help leverage their individual skills in tandem. To take advantage of the technology, you'll need to sign up to Ring's new subscription product, dubbed Protect Pro. The package offers cloud video storage, professional monitoring, Alexa Guard Plus, 24/7 backup internet for your security devices (via an LTE module in the Ring Pro base station) and Eero's cybersecurity subscription product for network protection. This, at least in the US as it launches, will set you back $20 a month, or $200 per year per location up front.

At the same time, Ring is launching a system dubbed "Virtual Security Guard," which connects users to third-party security guards. You'll need to pay for that separately, but you can hand over access to select Ring camera feeds to those companies who can keep a watch over your property. It is only when motion is detected that an operator can access your feed, and can speak to whoever is there to determine their intentions. Ring adds that third parties can't view motion events when the camera is disarmed, and can't download, share or save the clips of what's going on in your front yard. The first company to sign up for the program is Rapid Response, with others expected to join in the near future. The Virtual Security Guard service will require you to apply for early access, but the Ring Alarm Pro can be pre-ordered today for $250. (Since this isn't a Slashvertisement, we won't include a link to the product; you'll have to search for it yourself. Sorry not sorry.)

Amazon Just Revealed its First Home Robot (cnbc.com) 83

Posted by msmash from the how-about-that dept.
Amazon announced its long-rumored $999 Astro home robot on Tuesday. CNBC: I had a chance to check it out in a demo with Amazon last week and wanted to share a few thoughts on what Astro is, what it can and can't do and why Amazon decided to build a home robot. Astro seems like a strange gadget for Amazon to launch. The company is best known as an online store. And most of its operating profit comes from its AWS cloud business. Notably, Astro is a "Day 1 Edition" product, which means it won't be sold to everyone at first. [...] Astro is about the size of a small dog. It roams around your house on three wheels, including two big ones that prevent it from getting stuck and a smaller one for rotating. It has a camera that rises up on a 42-inch arm that can keep an eye on your home as Astro patrols while you're away. It can follow you around and play music or display TV shows on its 10-inch touchscreen. It can recognize faces (if you want it to) so you can load up two sodas in the back storage compartment and tell Astro to go to someone in the living room.

Astro is like a combo of lots of Amazon's other gadgets placed on wheels. The cameras can be used for home security or for video chat, sort of combining Amazon's Ring cameras with its Echo Show smart screens. The cameras are also used to create a map of your house when you set Astro up for the first time. You can talk to Astro much like you'd talk to an Echo or Alexa (you can change the name to Alexa if you want) to get sports scores or the weather. And you can play movies or TV shows like you would on an Amazon tablet or Fire TV.

A Tesla Big Battery Is Getting Sued Over Power Grid Failures In Australia (vice.com) 123

Posted by BeauHD from the broken-promises dept.
Tesla's Big Battery, located in southern Australia, just got hit with a federal lawsuit for failing to provide the crucial grid support it once promised it could. Motherboard reports: Built by Tesla in 2017, the 150-megawatt battery supplies 189 megawatt-hours of storage and was designed to support the grid when it becomes overloaded. Now operated by French renewable energy producer Neoen, it supplies storage for the adjacent Hornsdale wind farm, using clean energy to fill gaps that coal power leaves behind. It made waves at the time of its construction for being the largest lithium-ion battery in the world -- though it's now been superseded by another Tesla battery, the 300-megawatt Victorian Big Battery, also in Australia, which caught fire in July. On Wednesday, the Australian Energy Regulator (AER), the body that oversees the country's wholesale electricity and gas markets, announced it had filed a federal lawsuit against the Hornsdale Power Reserve (HPR) -- the energy storage system that owns the Tesla battery -- for failing to provide "frequency control ancillary services" numerous times over the course of four months in the summer and fall of 2019. In other words, the battery was supposed to supply grid backup when a primary power source, like a coal plant, fails.

The HPR's alleged pattern of failures was first brought to light during a disruption to a nearby coal plant in 2019, according to the regulator. When the nearby Queensland's Kogan Creek power station tripped on October 9, 2019, the HPR was called on to offer grid backup, having made offers to the Australian Energy Market Operator (AEMO) to do so. But the power reserve failed to provide the level of grid support that AEMO expected, and, in fact, was never able to do so in the first place, the lawsuit alleges, despite making money off of offering them. Though HPR did step in eventually, and no outages were recorded, the incident spurred investigation into a number of similar failures over the course of July to November 2019. The reserve's failure to support the grid in the way it promised created "a risk to power system security and stability," a press release on the lawsuit says.

Students Don't Know What Files And Folders Are, Professors Say (pcgamer.com) 186

Posted by BeauHD from the kids-these-days dept.
University students in courses from engineering to physics are having to be taught what files and folders are, The Verge reports, because that's not how they've grown up using computers. Whenever they need a file, they just search for it. PCGamer summarizes the findings: "I tend to think an item lives in a particular folder. It lives in one place, and I have to go to that folder to find it," astrophysicist Catherine Garland said. "They see it like one bucket, and everything's in the bucket." Strange as it may seem to older generations of computer users who grew up maintaining an elaborate collection of nested subfolders, thanks to powerful search functions now being the default in operating systems, as well as the way phones and tablets obfuscate their file structure, and cloud storage, high school graduates don't see their hard drives the same way.

"Students have had these computers in my lab; they'll have a thousand files on their desktop completely unorganized," Peter Plavchan, an associate professor of physics and astronomy at George Mason University, told The Verge. "I'm kind of an obsessive organizer ... but they have no problem having 1,000 files in the same directory. And I think that is fundamentally because of a shift in how we access files." As The Verge points out, "The first internet search engines were used around 1990, but features like Windows Search and Spotlight on macOS are both products of the early 2000s [...] While many of today's professors grew up without search functions on their phones and computers, today's students increasingly don't remember a world without them."

This isn't necessarily a bad thing, or a reason to recoil in horror because how dare the youth of today do things differently, why the very idea. "When I was a student, I'm sure there was a professor that said, 'Oh my god, I don't understand how this person doesn't know how to solder a chip on a motherboard,'" Plavachan said. "This kind of generational issue has always been around." And Garland, the astrophysicist teaching an engineering course, has started using her PC's search function to find files in the same way her students do. "I'm like, huh ... I don't even need these subfolders," she said.

Samsung Engineers Propose 'Copying and Pasting' the Brain onto AI Chips (engadget.com) 134

Posted by EditorDavid from the brain-dumps dept.
Samsung has proposed a way to build brain-like computer chips by "copying and pasting" a brain's neuron wiring map onto 3D neuromorphic chips. Engadget reports: The approach would rely on a nanoelectrode array that enters a large volumes of neurons to record both where the neurons connect and the strength of those connections. You could copy that data and 'paste' it to a 3D network of solid-state memory, whether it's off-the-shelf flash storage or cutting-edge memory like resistive RAM. Each memory unit would have a conductance that reflects the strength of each neuron connection in the map. The result would be an effective return to "reverse engineering the brain" like scientists originally wanted, Samsung said.

The move could serve as a 'shortcut' to artificial intelligence systems that behave like real brains, including the flexibility to learn new concepts and adapt to changing conditions. You might even see fully autonomous machines with true cognition, according to the researchers.
"Envisioned by the leading engineers and scholars from Samsung and Harvard University, the insight was published as a Perspective paper, titled 'Neuromorphic electronics based on copying and pasting the brain'..." Samsung said in a statement.

In short, they're proposing a method that "directly downloads the brain's neuronal connection map onto the memory chip."

Samoa Scraps Daylight Saving Time 159

Posted by BeauHD from the who's-next? dept.
Samoa is joining Japan, India, and China in scrapping daylight saving time, which was first proposed in 1895 so entomologist and astronomer George Hudson could study insects at night. "Hudson is dead, so daylight saving is no longer necessary," writes Mark Frauenfelder via BoingBoing. "It's time for the rest of the world to wake up and do the same." Time and Date reports: "The Ministry hereby advises that the Daylight Saving Time (DST) policy has ceased as per Cabinet Decision [...]. There will be no activation of the Daylight Saving Time policy for this year." The announcement (PDF) came from the Government of Samoa on September 20, 2021, following a decision made by Samoa's new Government Cabinet on September 15, 2021. DST was implemented in 2010 by the previous Government of Samoa to give more time after work to tend to their plantations, promote public health, and save fuel. Instead, it "[...] defeated its own goals by being used by people to socialize more," according to the Samoa Observer.

Today's Students Don't Understand the Basics of Computer Operations (theverge.com) 493

A new article in The Verge reports that professors are increasingly seeing the rise of a generation that can't understand even the basic fundamentals of how computers and operating systems work. The very concept of things like directories, folders, and even what a file is seem to baffle a generation that was raised on Google and smartphones, and have no concept of what storage is or how it works. To this generation, all your "stuff" just goes someplace where stuff is kept. Physics professor Catherine Garland was stunned to find that her students couldn't grasp the concept of organized file storage:

"She asked each student where they'd saved their project. Could they be on the desktop? Perhaps in the shared drive? But over and over, she was met with confusion. "What are you talking about?" multiple students inquired. Not only did they not know where their files were saved -- they didn't understand the question.

Gradually, Garland came to the same realization that many of her fellow educators have reached in the past four years: the concept of file folders and directories, essential to previous generations' understanding of computers, is gibberish to many modern students.

The new generation of students sees storage as a "giant laundry basket", where everything is just thrown in, and you go get what you need when you need it. One professor now incorporates an additional two hour lecture and demo in their subject just to teach new students how things like directories work in computer systems. Teachers worry that students will be ill-prepared for professional environments, especially STEM fields, that require rigid organization to keep volumes of data organized. But some professors seem to think that they'll eventually have to surrender to how the young do things.

How Google Spies on Its Employees (theinformation.com) 32

Posted by msmash from the closer-look dept.
At Google, a seemingly innocuous action can earn an employee the attention of the company's corporate security department. The Information: For example, when Google wants to find out who has been accessing or leaking sensitive corporate information, the company often homes in on employees who are thinking about leaving it. In the past, its security teams have flagged employees who search an internal website listing the cost of COBRA health insurance -- which gives workers a way to continue their coverage after leaving their employer -- for further investigation, according to a person with direct knowledge of its tactics. Employees who draft resignation letters or seek out internal checklists that help workers plan their departures from Google have also faced similar scrutiny, the person said. It has even looked at who has taken screenshots on work devices while running encrypted messaging services at the same time, according to current and former employees with knowledge of the practices. Bulk transfers of data onto USB storage devices and use of third-party online storage services can also raise eyebrows among Google's security staff.
