Razer's Viper 8K is a refresh of the 2019 true ambidextrous Viper. For the most part, it's identical and is now available at the same $79 asking price, but it has some key upgrades for competitive gamers who are hoping that tech might help them get the edge over their opponents. From a report: First off, Razer now includes the Focus Plus 20,000DPI sensor used in many of its other 2020 mice, along with the latest generation of optical switches that have a more tactile click feel, according to the company (although it didn't stand out as noticeable to me when I tested the mouse). The biggest news is that, according to Razer, the newly revised Viper can achieve the fastest polling rate of any mouse currently available: up to 8,000Hz -- far higher than the industry standard of 1,000Hz. The polling rate measures how often per second the mouse tells your computer where it's located on-screen. The more frequent the polling is, the smoother your mouse tracking can be. In the case of Razer's new Viper 8K, an 8,000Hz polling rate can deliver a whopping 8,000 pings to your PC per second, while reducing the response time of those pings from one millisecond to just an eighth of one millisecond. On paper, it seems really impressive.

Thelasko shares a report from CNET: Navistar, the company formerly known as International Harvester, announced on Wednesday that it's partnering with GM and OneH2 for a "complete solution for customer implementation of a zero-emission long-haul system," which is a fancy way of saying an entire ecosystem devoted to electric trucking. The group will work together on the trucks themselves, in addition to the ancillary stuff required to keep them operating.

It starts with the trucks, which in this case will be International RH Series hydrogen fuel-cell electric trucks. Each RH Series semi will get two GM Hydrotec fuel cell power cubes, each of which contains more than 300 hydrogen fuel cells in addition to the management systems that run the whole show. Navistar plans to have these trucks ready for commercial purchase in the 2024 model year, with test models operating in a pilot phase by the end of 2022. The hope is that these trucks will pack a range of 500 miles or more with a fueling time of less than 15 minutes and Navistar hopes that its propulsion system will sport a per-mile cost similar to diesel.

When it comes to the fuel itself, that's where OneH2 comes into play. Navistar will rely on the company for the production, storage and safe delivery of the compressed hydrogen required to power the trucks. To deepen the partnership, Navistar announced that it will purchase a minority stake in OneH2, as well. OneH2 doesn't just deal in gas-station-style fill up locations; the company has a mobile fueling solution, too, which should help in the early stages as the US' hydrogen fuel infrastructure is still very much in its infancy. [...] Navistar has chosen J.B. Hunt Transport to be in charge of its vehicles during the pilot program. J.B. Hunt, a name you've likely seen on the highway, will put Navistar's GM-powered International models on dedicated routes to see how these vehicles perform in place of traditional diesel-powered semi trucks.

MojoKid writes: This morning, NVIDIA lifted its embargo on the performance and experiences of new GeForce RTX 30 Series-powered gaming laptops. Thinner, higher-performance form factors aren't the only features NVIDIA is touting with this launch. A number of new laptops will also sport 1440p, high refresh rate IPS displays like the MSI GS66 Stealth with a GeForce RTX 3080 mobile GPU tested at HotHardware. This machine features a 15.6-inch IPS, 1440p panel with a 240Hz refresh rate and G-Sync support. However, the biggest difference between these new laptop GeForce RTX 30 series GPUs and their desktop counterparts, are their core counts. Desktop GeForce RTX 3080, 3070, and 3060 series GPUs have 8,704, 5,888, and 3,584 CUDA cores, respectively, whereas these new laptop offerings have 6,144, 5,120, and 3,840 -- it is only the RTX 3060 laptop GPU that has more cores than its similar-branded desktop counterpart.

In the benchmarks, with a retail-ready Alienware m15 R4 gaming laptop powered by a GeForce RTX 3070 mobile GPU, the new platform offered sizable performance gains of 15-25% over the previous generation RTX 20 series mobile offering, and an even stronger performance lift with ray tracing enabled, sometimes in excess of 40%. NVIDIA GeForce 30 Series laptops are in production now and available in the next few weeks from major OEMs like Alienware, ASUS, MSI, Gigabyte and others.

An anonymous reader quotes a report from The Verge: Amazon is enabling a new feature today that allows Alexa to proactively complete tasks around the house, such as turning off lights, based on your habits and frequent requests. Alexa has been able to sense these habits and ask about them since 2018 -- the company calls them "hunches" -- but before this update, Alexa would ask permission before acting on something like lowering the thermostat before you went to bed. If the new proactive hunches are enabled, though, Alexa will skip asking for permission for a task and just do it.

While proactive hunches seem like they could make Alexa a lot more useful, having granular controls over what Alexa can automatically act on will be important. An Amazon support article seems to suggest you can select what types of hunches Alexa can complete on its own, but we've reached out to Amazon for more information on how much you can customize proactive hunches. In addition, Amazon is rolling out its Guard Plus security subscription service. "The service can alert you if Alexa picks up on certain types of sounds in your home and offers access to human agents who can call emergency services on your behalf, similar to ADT," reports The Verge. It'll cost $4.99 per month.

The company is also rolling out an energy dashboard via the Alexa app that can monitor and estimate how much power compatible devices connected to Alexa use if their manufacturers support it.

Dan Riccio has served as senior VP of engineering overseeing all of Apple's hardware since 2012, but now he's stepping back from that role. A press release revealed he's focusing on a mysterious "new project" at Apple and will still report directly to CEO Tim Cook. Engadget reports: Exactly what that new project is remains unclear, although recent rumors have pointed to Apple's plans for augmented and virtual reality or building an electric car. Of course, maybe it's a differently color iPhone or an even-more-expensive pair of noise-cancelling headphones. Riccio previously lead the iPad team before taking over as senior VP, and oversaw projects all the way up to the recently-launched AirPods Max.

Replacing Riccio on Apple's executive team is John Ternus, who has been the VP of hardware engineering since 2013, and is noted as a key figure in Apple's rollout of its new M1 CPUs. Meanwhile, Riccio will still hold the title of vice president of engineering and "play an instrumental role in shaping the future of Apple's products."

Renewable energy became the biggest source of electricity in the European Union in 2020, beating fossil fuels for the first time. Germany and Spain also hit that milestone individually last year -- so did the UK, which officially left the EU in January 2020. From a report: Renewables powered 38 percent of electricity in the EU last year, according to a report released today by energy think tanks Ember and Agora Energiewende. That gives renewable energy a narrow lead over fossil fuel-fired generation, which accounted for 37 percent of Europe's electricity. The remaining quarter comes from nuclear energy.

The rise of renewables is good news for the health of the planet. Still, renewable energy will need to grow at an even faster rate to stave off a future with more climate change-induced disasters. "Renewables overtaking fossils is an important milestone in Europe's clean energy transition. However, let's not be complacent," Patrick Graichen, director of Agora Energiewende, said in a statement. "Post-pandemic recovery [programs] need to go hand-in-hand with accelerated climate action."

Reuters reports on big changes at BP (the company formerly known as British Petroleum): Its geologists, engineers and scientists have been cut to less than 100 from a peak of more than 700 a few years ago, company sources told Reuters, part of a climate change-driven overhaul triggered last year by CEO Bernard Looney. "The winds have turned very chilly in the exploration team since Looney's arrival. This is happening incredibly fast," a senior member of the team told Reuters.

Hundreds have left the oil exploration team in recent months, either transferred to help develop new low-carbon activities or laid off, current and former employees said. The exodus is the starkest sign yet from inside the company of its rapid shift away from oil and gas, which will nevertheless be its main source of cash to finance a switch to renewables for at least the next decade. BP declined to comment on the staffing changes, which have not been publicly disclosed... Looney made his intentions clear internally and externally by lowering BP's production targets and becoming the first oil major CEO to promote this as a positive to investors seeking a long-term vision for a lower-carbon economy.

BP is cutting some 10,000 jobs, around 15% of its workforce, under Looney's restructuring, the most aggressive among Europe's oil giants including Royal Dutch Shell and Total. The 50-year-old, a veteran oil engineer who previously headed the oil and gas exploration and production division, aims to cut output by 1 million barrels per day, or 40%, over the next decade while growing renewable energy output 20 fold.
Elsewhere Reuters reports that due to the pandemic, acquisitions of new onshore and offshore exploration licences for the top five Western energy companies "dropped to the lowest in at least five years," citing data from Oslo-based consultancy Rystad Energy.

After their house was vandalized, long-time Slashdot reader lsllll needs some help finding a battery-powered, wifi-enabled camera that can dump motion-detected videos to a local server: There are some nice cameras out there that'll work for nearly 5 months off a rechargeable battery. You can even pair them with a solar panel which would keep them constantly topped off. But none of them offer anything other than local storage (free on SD card) or in the cloud (subscription).

Obviously, being a programmer and a sysadmin, I realize that the effort to dump a video to a cloud service and opening a connection to a local FTP/SMB server require the same bandwidth, battery usage. So this decision to not support local FTP/SMB servers must be intentional and the way everything is going nowadays: juice the customers for as much money as you can after they've purchased your product.

The question is, are the any cameras out there that run on rechargeable batteries, support WiFi, and dump videos to a local server?

An anonymous reader quotes a report from The Guardian: Electric vehicles are close to the "tipping point" of rapid mass adoption thanks to the plummeting cost of batteries, experts say. Global sales rose 43% in 2020, but even faster growth is anticipated when continuing falls in battery prices bring the price of electric cars dipping below that of equivalent petrol and diesel models, even without subsidies. The latest analyses forecast that to happen some time between 2023 and 2025.

The tipping point has already been passed in Norway, where tax breaks mean electric cars are cheaper. The market share of battery-powered cars soared to 54% in 2020 in the Nordic country, compared with less than 5% in most European nations. Prof Tim Lenton, at the University of Exeter, said: "There's been a tipping point in one country, Norway, and that's thanks to some clever and progressive tax incentives. Then consumers voted with their wallets."

Data from Lenton's latest study showed that in 2019, electric vehicles in Norway were 0.3% cheaper and had 48% market share. In the UK, where electric cars were 1.3% more expensive, market share was just 1.6%. Once the line of price parity was crossed, Lenton said, "bang -- sales go up. We were really struck by how non-linear the effect seems to be." BloombergNEF's analysis predicts lithium-ion battery costs will fall to the extent that electric cars will match the price of petrol and diesel cars by 2023, while Lenton suggests 2024-2025. McKinsey's Global Energy Perspective 2021, published on January 15, forecasts that "electric vehicles are likely to become the most economic choice in the next five years in many parts of the world."

An anonymous reader quotes a report from Electrek: The DMC DeLorean has been out of production for almost 40 years, but now we've learned that the iconic vehicle might be coming back as an electric car. In 1995, Stephen Wynne bought the company's old inventory and trademark to relaunch the brand based in Texas. At first, the plan was to bring back the same vehicle with more modern technology in low volume. For the past 5 years, the company pushed for the adoption of new rules for low volume vehicle production with the National Highway Traffic Safety Administration (NHTSA). These new rules were finally recently adopted, but the delay was so long that it complicated DeLorean's plans. The engine that they plan to use is not going to be compliant with emission standards starting in 2022 and the landscape has changed significantly.

In a new blog post, the company is now hinting that going electric with the DeLorean: "That said, with EV's becoming more mainstream, we've been considering switching to an all-electric as the future. It certainly makes for an easier path through emissions maze which still looms large over any internal combustion engine. While an electric Cobra or Morgan may be a little extreme for their potential market, we've already seen that an EV DeLorean -- as we displayed at the 2012 New York International Auto Show -- is not such an 'out there' idea." The company hints at being in the process of looking to secure financing to bring an electric DeLorean and says "stay tuned."

Meet the Raspberry Pi Pico, a tiny little microcontroller that lets you build hardware projects with some code running on the microcontroller. Even more interesting, the Raspberry Pi Foundation is using its own RP2040 chip, which means that the foundation is now making its own silicon. From a report: If you're not familiar with microcontrollers, those devices let you control other parts or other devices. You might think that you can already do this kind of stuff with a regular Raspberry Pi. But microcontrollers are specifically designed to interact with other things. They're cheap, they're small and they draw very little power. You can start developing your project with a breadboard to avoid soldering. You can pair it with a small battery and it can run for weeks or even months. Unlike computers, microcontrollers don't run traditional operating systems. Your code runs directly on the chip.

Like other microcontrollers, the Raspberry Pi Pico has dozens of input and output pins on the sides of the device. Those pins are important as they act as the interface with other components. For instance, you can make your microcontroller interact with an LED light, get data from various sensors, show some information on a display, etc. The Raspberry Pi Pico uses the RP2040 chip. It has a dual-core Arm processor (running at 133MHz), 264KB of RAM, 26 GPIO pins including 3 analog inputs, a micro-USB port and a temperature sensor. It doesn't come with Wi-Fi or Bluetooth. And it costs $4.

Investments into clean-energy technologies totaled more than $500 billion for the first time ever, according to a BloombergNEF report released Tuesday. Axios reports: Technologies making energy and other material cleaner needs to expand rapidly if the world is to adequately address climate change in the coming decades. Global investment in the low-carbon energy transition was $501.3 billion in 2020, up 9% from 2019 despite the pandemic driving the world into a recession. This tally includes investments in renewables, energy storage, electric vehicle charging stations, hydrogen production, carbon capture projects and more. The largest areas of investment are renewable energy and electrified transportation.

The report also reflects another broader trend, which is that investment often lags in technologies beyond renewable electricity and electric cars. This includes carbon capture and most industrial processes like cement, according to the International Energy Agency.

schwit1 shares a report from Penn State University: Range anxiety, the fear of running out of power before being able to recharge an electric vehicle, may be a thing of the past, according to a team of Penn State engineers who are looking at lithium iron phosphate batteries that have a range of 250 miles with the ability to charge in 10 minutes. "We developed a pretty clever battery for mass-market electric vehicles with cost parity with combustion engine vehicles," said Chao-Yang Wang, William E. Diefenderfer Chair of mechanical engineering, professor of chemical engineering and professor of materials science and engineering, and director of the Electrochemical Engine Center at Penn State. "There is no more range anxiety and this battery is affordable." The researchers also say that the battery should be good for 2 million miles in its lifetime.

They report today (Jan. 18) in Nature Energy that the key to long-life and rapid recharging is the battery's ability to quickly heat up to 140 degrees Fahrenheit, for charge and discharge, and then cool down when the battery is not working. The battery uses a self-heating approach previously developed in Wang's center. The self-heating battery uses a thin nickel foil with one end attached to the negative terminal and the other extending outside the cell to create a third terminal. Once electrons flow it rapidly heats up the nickel foil through resistance heating and warm the inside of the battery. Once the battery's internal temperature is 140 degrees F, the switch opens and the battery is ready for rapid charge or discharge. [...] Because of the self-heating, the researchers said they do not have to worry about uneven deposition of lithium on the anode, which can cause lithium spikes that are dangerous.

"Researchers claim achievement of new record photovoltaic conversion efficiencies for perovskite-based solar cells by spicing them up with a little capsaicin," writes Slashdot reader ffkom, adding: "Of course everyone who loves to eat chilis already knew capsaicin energizes you to record levels." The researchers have published their findings in the journal Joule. From the report: Perovskite solar cells (PSCs) suffer from significant nonradiative recombination, limiting their power conversion efficiencies. Here, for the first time, we directly observe a complete transformation of perovskite MAPbI 3 surface region energetics from p- to n-type during defect passivation caused by natural additive capsaicin, attributed to the spontaneous formation of a p-n homojunction in perovskite active layer. We demonstrate that the p-n homojunction locates at 100 nm below perovskite surface. The energetics transformation and defect passivation promote charge transport in bulk perovskite layer and at perovskite/PCBM interface, suppressing both defect-assisted recombination and interface carrier recombination. As a result, an efficiency of 21.88% and a fill factor of 83.81% with excellent device stability are achieved, both values are the highest records for polycrystalline MAPbI 3 based p-i-n PSCs reported to date. The proposed new concept of synergetic defect passivation and energetic modification via additive provides a huge potential for further improvement of PSC performance.

An anonymous reader quotes a report from NBC News: A Pennsylvania woman accused of being one of the Capitol rioters told a former "romantic partner" that she planned to steal a laptop computer from House Speaker Nancy Pelosi's office and sell it to Russian intelligence, court documents revealed Monday. The woman, Riley June Williams, 22, was on the run, charged with disorderly conduct on Capitol grounds with the intent to disturb a session of Congress and other charges after her former flame turned her in.

"Williams is not in custody," a federal law enforcement officials said Monday afternoon. William's ex, who was described in Special Agent Jonathan Lund's charging document as W1 (witness one), called the FBI and told it that she "intended to send the computer device to a friend in Russia, who then planned to sell the device to SVR, Russia's foreign intelligence service." "According to W1, the transfer of the computer device to Russia fell through for unknown reasons and Williams still has the computer device or destroyed it," the document states. Lund said the device and circumstances of what Williams was doing with it remain under investigation. The laptop was reported stolen from the conference room on Jan. 6 but was "only used for presentations," according to Pelosi's deputy chief of staff, Drew Hamill.

"American automakers are asking the U.S. government to help solve a debilitating shortage of computer chips that is closing auto factories worldwide and could restrict production until the fall," reports Bloomberg: The American Automotive Policy Council — a lobbying organization for General Motors Co., Ford Motor Co. and the U.S. operations of Fiat Chrysler Automobiles NV — is agitating with the U.S. Commerce Department and the incoming administration of President-elect Joe Biden to press Asian semiconductor makers to reallocate output away from consumer electronics and build essential chips for cars.

"We have requested that the U.S. government help us find a solution to the problem because it will diminish our production and have a negative impact on the U.S. economy until it's resolved," Matt Blunt, president of the AAPC, said in an interview Friday. "We are not primarily concerned with where blame may lie for this global shortage, if it lies anywhere, but we just want a solution. And the solution is more automobile-sector semiconductors."

The shortage forced Ford to shut a sport-utility vehicle factory in Kentucky this week, and it is closing a small-car plant in Germany for a month. Fiat Chrysler has had to temporarily stop output at plants in Mexico and Canada. More production is expected to be idled in the coming weeks.

Long-time Slashdot reader AmiMoJo quotes IEEE Spectrum: Computers use a staggering amount of energy today. According to one recent estimate, data centers alone consume two percent of the world's electricity, a figure that's expected to climb to eight percent by the end of the decade. To buck that trend, though, perhaps the microprocessor, at the center of the computer universe, could be streamlined in entirely new ways.

One group of researchers in Japan have taken this idea to the limit, creating a superconducting microprocessor — one with zero electrical resistance. The new device, the first of its kind, is described in a study published last month in the IEEE Journal of Solid-State Circuits ...

The price of entry for the niobium-based microprocessor is of course the cryogenics and the energy cost for cooling the system down to superconducting temperatures. "But even when taking this cooling overhead into account," says Christopher Ayala, an Associate Professor at the Institute of Advanced Sciences at Yokohama National University, in Japan, who helped develop the new microprocessor, "The AQFP is still about 80 times more energy-efficient when compared to the state-of-the-art semiconductor electronic device, [such as] 7-nm FinFET, available today."

An anonymous reader quotes a report from The Register: In 2010, Austin Sendek, then a physics student at UC Davis, created a petition seeking recognition for prefix "hella-" as an official International System of Units (SI) measurement representing 10^27. "Northern California is home to many influential research institutions, including the University of California, Davis, the University of California, Berkeley, Stanford University, and the Lawrence Livermore and Lawrence Berkeley National Laboratories," he argued. "However, science isn't all that sets Northern California apart from the rest of the world. The area is also the only region in the world currently practicing widespread usage of the English slang 'hella,' which typically means 'very,' or can refer to a large quantity (e.g. 'there are hella stars out tonight')."

To this day, the SI describes prefixes for quantities for up to 10^24. Those with that many bytes have a yottabyte. If you only have 10^21 bytes, you have a zettabyte. There's also exabyte (10^18), petabyte (10^15), terabyte (10^12), gigabyte(10^9), and so on. Support for "hella-" would allow you to talk about hellabytes of data, he argues, pointing out that this would make the number of atoms in 12 kg of carbon-12 would be simplified from 600 yottaatoms to 0.6 hellaatoms. Similarly, the sun (mass of 2.2 hellatons) would release energy at 0.3 hellawatts, rather than 300 yottawatts. [...] The soonest [a proposal for a "hella-" SI could be officially adopted] is in November 2022, at the quadrennial meeting of the International Bureau of Weights and Measures (BIPM)'s General Conference on Weight and Measures, where changes to the SI usually must be agreed upon. The report notes that Google customized its search engine in 2010 to let you convert "bytes to hellabytes." A year later, Wolfram Alpha added support for "hella-" calculations.

"Sendek said 'hellabyte' initially started as a joke with some college friends but became a more genuine concern as he looked into how measurements get defined and as his proposal garnered support," reports The Register. He believes it could be useful for astronomical measurements.

In addition to upgraded MacBook Pros, Bloomberg reports that Apple is also "planning the first redesign of its iMac all-in-one desktop computer since 2012," as it shifts away from Intel to its own silicon. From the report: The new models will slim down the thick black borders around the screen and do away with the sizable metal chin area in favor of a design similar to Apple's Pro Display XDR monitor. These iMacs will have a flat back, moving away from the curved rear of the current iMac. Apple is planning to launch two versions -- codenamed J456 and J457 -- to replace the existing 21.5-inch and 27-inch models later this year, the people said, asking not to be identified because the products are not yet announced. The new models will use next-generation versions of Apple's Mac processors like the upcoming 2021 MacBook Pros. The iMac redesign will be one of the biggest visual updates to any Apple product this year, according to people familiar with the company's roadmap.

Apple is also working on a pair of new Mac Pro desktop computers, its priciest Mac machines that don't come with a screen included, the people said. One version is a direct update to the current Mac Pro and will continue to use the same design as the version launched in 2019. Apple has discussed continuing to use Intel processors for that model rather than moving to its own chips. The second version, however, will use Apple's own processors and be less than half the size of the current Mac Pro. The design will feature a mostly aluminum exterior and could invoke nostalgia for the Power Mac G4 Cube, a short-lived smaller version of the Power Mac, an earlier iteration of the Mac Pro. Apple has also reportedly started development of a cheaper external monitor to sell alongside the Pro Display XDR. "The cheaper monitor would feature a screen geared more for consumer than professional use and wouldn't have the brightness and contrast ratio of the top-tier offering," reports Bloomberg.

An anonymous reader quotes a report from Ars Technica: The "instant on" feature that's activated by default on new Xbox Series S/X consoles could suck up a total of 4 billion kWh -- the equivalent of a year's operation for a large power plant -- from US owners alone through 2025. That's according to a preliminary report released this week from the Natural Resources Defense Council, an environmentally focused nonprofit advocacy group. As the name implies, the "instant on" feature of the Series S/X (and the Xbox One before it) lets users skip the usual startup time when turning the console back on. That saves about 10 to 15 seconds of waiting per power cycle on the Series S/X, down from about 45 seconds on the Xbox One.

"Instant on" standby also lets the system check periodically for system updates in order to download and install them in between play sessions. But leaving the "instant on" feature active means the Xbox Series S/X draws nine to 10 watts of power 24 hours a day -- even when it's not being actively used -- compared to less than 1W if the standby settings are switched to "energy saving" mode. The Xbox Series S/X initially drew 25 to 28W of "instant on" standby power at launch, but a recent firmware update caused a dramatic reduction, placing the new systems below the ~13W drawn by the Xbox One's "instant on" mode. The PlayStation 5, by contrast, uses between 1 and 2 watts when sitting idle in "rest mode."
