Scientists have used 3D computer modeling to figure out how the world's oldest "computer" worked. BBC reports: The Antikythera Mechanism has baffled experts since it was found on a Roman-era shipwreck in Greece in 1901. The hand-powered Ancient Greek device is thought to have been used to predict eclipses and other astronomical events. But only a third of the device survived, leaving researchers pondering how it worked and what it looked like. Scientists from University College London (UCL) believe they have finally cracked the puzzle using 3D computer modeling. They have recreated the entire front panel, and now hope to build a full-scale replica of the Antikythera using modern materials.

On Friday, a paper published in Scientific Reports revealed a new display of the gearing system that showed its fine details and complex parts. The mechanism has been described as an astronomical calculator as well as the world's first analogue computer. It is made of bronze and includes dozens of gears. The back cover features a description of the cosmos display, which shows the motion of the five planets that were known at the time the device was built. But only 82 fragments -- amounting to around a third of the device -- survived, This meant scientists have had to piece together the full picture using X-Ray data and an Ancient Greek mathematical method.

An official version of the popular 7-zip archiving program has been released for Linux for the first time. Bleeping Computer reports: Linux already had support for the 7-zip archive file format through a POSIX port called p7zip but it was maintained by a different developer. As the p7zip developer has not maintained their project for 4-5 years, 7-Zip developer Igor Pavlov decided to create a new official Linux version based on the latest 7-Zip source code. Pavlov has released 7-Zip for Linux in AMD64, ARM64, x86, and armhf versions, which users can download [via their respective links].

"These new 7-Zip binaries for Linux were linked (compiled) by GCC without -static switch. And compiled 32-bit executables (x86 and armhf) didn't work on some arm64 and amd64 systems, probably because of missing of some required .so files." "Please write here, if you have some advices how to compile and link binaries that will work in most Linux systems," Pavlov stated on his release page.

Adobe today officially unveiled Photoshop for Apple's M1 chip, claiming it provides a 50% performance boost compared to analogous Intel Macs. The Next Web reports: While Adobe has had a beta version of Photoshop for M1 available since November, this is the first time it's been available widely. Previously Apple users could run the Intel version through Apple's Rosetta technology, which didn't fully take advantage of the new chip's power.

[According to Adobe:] "Our internal tests show a wide range of features running an average of 1.5X the speed of similarly configured previous generation systems. Our tests covered a broad scope of activities, including opening and saving files, running filters, and compute-heavy operations like Content-Aware Fill and Select Subject, which all feel noticeably faster. Our early benchmarking also shows that some operations are substantially faster with the new chip." Be warned that there are a couple of recent features missing on the M1 version of the app, most notably inviting others to edit cloud documents and preset syncing.

MojoKid writes: Some may think it strange to design and build an entire PC and custom enclosure, dedicated to running a 20-year-old screensaver, but retro computing fans and well-seasoned enthusiasts may remember the SereneScreen Marine Aquarium. This classic screensaver from the late 90s was created by the legendary artist of Defender of the Crown and more, Jim Sachs. SereneScreen's combination of beautiful fish and technology is still mesmerizing, so why not build a miniature, 3D-printed aquarium and power it with a single board computer like the Rock Pi X and a 1920X480 resolution IPS LCD display? That's just what product developer Colton Westrate did.

Searching for an x86 PC in a Raspberry Pi-sized form factor, Westrate chose the Rock Pi X that purportedly packs the perfunctory punch to push the Windows OS and aquarium screen saver's pulsating pixels. The Rock Pi X is based on a circa 2016 Intel x5-Z8350 processor, which is a 2-watt, quad-core Cherry Trail Atom chip. From there, with a little Fusion 360 parametric modeling, a clear acrylic napkin holder, and some serious skills, Westrate created this adorable pint-sized digital fish tank. There's a full parts list and how-to guide on HotHardware, along with links to the CAD files up on Thingiverse, so you can build yourself one too, if you're feeling inspired.

nickwinlund77 shares a report from NPR: Lou Ottens, who put music lovers around the world on a path toward playlists and mixtapes by leading the invention of the first cassette tape, has died at age 94, according to media reports in the Netherlands. Ottens was a talented and influential engineer at Philips, where he also helped develop consumer compact discs. Ottens died last Saturday, according to the Dutch news outlet NRC Handelsblad, which lists his age as 94. The cassette tape was Ottens' answer to the large reel-to-reel tapes that provided high-quality sound but were seen as too clunky and expensive. He took on the challenge of shrinking tape technology in the early 1960s, when he became the head of new product development in Hasselt, Belgium, for the Dutch-based Philips technology company.

"Lou wanted music to be portable and accessible," says documentary filmmaker Zack Taylor, who spent days with Ottens for his film Cassette: A Documentary Mixtape. Ottens' goal was to make something simple and affordable for anyone to use. As Taylor says, "He advocated for Philips to license this new format to other manufacturers for free, paving the way for cassettes to become a worldwide standard."

An anonymous reader quotes a report from MacRumors: Apple will soon be making a significant change to its serial number format for future products that will see some key information stripped out. In an internal AppleCare email this week, obtained by MacRumors, Apple said the new serial number format will consist of a randomized alphanumeric string of 8-14 characters that will no longer include manufacturing information or a configuration code. Apple said the serial number format transition is scheduled for "early 2021," and confirmed that IMEI numbers will not be affected by this change.

Any currently shipping Apple products will continue to use the current serial number format, while future products will use the new format, according to Apple. The new serial numbers will initially be 10 characters, the company indicated. Apple's current serial number format has long allowed both customers and service providers to determine the date and location that a product was manufactured, with the first three characters representing the manufacturing location and the following two indicating the year and week of manufacture. The last four characters currently serve as a "configuration code," revealing a device's model, color, and storage capacity. Apple initially planned to transition to the new serial number format in late 2020, but delayed. Apple hasn't explained the reasons for the change, but the new format will effectively make it impossible to view details about when and where a device is manufactured.

HTC's latest tease on its Twitter account looks related to the lip-tracking module for its Vive headsets. UploadVR reports: Paired with last week's tease that included the message "It's your move," plus numerous replies that use the word 'tracking' and even a more recent reference to Avatar, it certainly seems like HTC is teasing new add-ons for its existing Vive headsets, rather than an all-new device.

HTC revealed the lip-tracking module for Vive all the way back at GDC 2019. At the time the company said it had no plans for a full release of the device. The kit hangs below the headset and reads movement in your mouth, which a given experience could then use to replicate on a virtual avatar of yourself. Paired with the eye-tracking in the HTC Vive Pro Eye, it's feasible that HTC could soon be bringing very expressive virtual avatars to VR. Go a step further and implement the Vive Trackers for full-body tracking, and there's a lot of potential here.

A user shares a report from Apple Insider: Researchers are working on a cabling system that could provide data transfer speeds multiple times faster than existing USB connections using an extremely thin polymer cable, in a system that echoes the design path of Thunderbolt. Presented at the February IEEE International Solid-State Circuits Conference, the research aims to develop a connection type that offers far better connectivity than current methods. In part, it aims to accomplish this by replacing copper wiring with something else.

Copper is typically used for wires like USB and HDMI to handle data transfers, but it requires a lot of power to work for high levels of data transmission. "There's a fundamental tradeoff between the amount of energy burned and the rate of information exchanged," said MIT alumni and lead author Jack Holloway. While the "increasingly bulky and costly" copper could be replaced by fiber optic cables, that introduces its own issues. As silicon chips have difficulty dealing with photons, this makes the interconnection between the cable and the computers more challenging to optimize. Combining the benefits of copper and fiber optic conduits, a plastic polymer is used by the researchers. This makes it cheaper to manufacture than copper wires, which could be an attractive proposition for cable producers.

The polymer can also use sub-terahertz electromagnetic signals, which is more energy-efficient than copper at high data loads. It is believed this efficiency brings it close to that of fiber optic systems, but crucially with better compatibility with silicon chips. Low-cost chips are paired with the polymer conduit that can generate the high-frequency signals powerful enough to transmit into the conduit directly. As such, the system is expected to be manufactured with standard methods, which also makes it cost-effective to produce. The cables themselves can also be extremely thin, with the cross-sectional area of the interconnect measuring 0.4 millimeters by a quarter millimeter, smaller than typical copper variants. That small hair-like cable can be used to transport data over three different parallel channels, enabling it to achieve a total bandwidth of 105 gigabits per second. Bundling conduits together could bring the cables into the terabit-per-second range, while still remaining at a reasonable cost.

LG's battery division is planning to build advanced battery cells for Tesla's electric vehicles in 2023 and is considering potential production sites in the U.S. and Europe, according to Reuters. From the report: Tesla has not yet agreed to a deal that would expand LG's role in its supply chain beyond China, one of the sources said. Last week, the Korean battery maker told Korean reporters it plans to build a U.S. factory where it would make battery cells for EVs and energy storage systems, to cater to U.S. and global customers as well as startups. It did not identify potential customers then, but one of the sources said it was hoping Tesla would buy the batteries.

In September, Tesla Chief Executive Elon Musk announced an ambitious plan to develop new cells in-house, prompting suppliers like LG and Panasonic to embrace the unproven technology or face risks of losing a major customer for the longer term. The Korean supplier, a unit of LG Chem, has made samples for the so-called 4680 large-format cylindrical cells, said the sources, who asked not to be identified. It faces technological hurdles and the challenge of scaling up production, people familiar with the matter said.

"LG plans to produce 4680 cells at its new U.S. factory. They plan to build a new 4680 cell line to supply Tesla's Giga Berlin in Europe," one of the sources said, adding Spain is one of candidate for the European plant. One of the sources said LG has never mass produced such large-format cylindrical cells, although increasing battery capacity is the correct call. "Tesla is a major customer, and LG can take risks," another source said. He said LG has not yet secured orders from Tesla for the 4680 cells, still under development. For now, Tesla is sharply boosting orders for 2170 cells used in the Model 3 and Model Y vehicles made in China, the source said.

Dropbox announced today that it plans to acquire DocSend for $165 million. The company helps customers share and track documents by sending a secure link instead of an attachment. From a report: "We're announcing that we're acquiring DocSend to help us deliver an even broader set of tools for remote work, and DocSend helps customers securely manage and share their business critical documents, backed by powerful engagement analytics," Houston told me. When combined with the electronic signature capability of HelloSign, which Dropbox acquired in 2019, the acquisition gives the company an end-to-end document sharing workflow it had been missing. "Dropbox, DocSend and HelloSign will be able to offer a full suite of self-serve products to help our millions of customers manage the entire critical document workflows and give more control over all aspects of that," Houston explained.

MIPS Technologies, the company that had been synonymous with the MIPS processor architecture, will now be developing processors based on RISC-V architecture. TuxPhones reports: The MIPS silicon manufacturer is one of the oldest RISC chip manufacturers, used in several systems since the late 80s. Characterized by clean and efficient designs, allowing adaption in varied applications, this company has been considered one of the most innovative in the market during its golden age - to the point that the Windows OS had a MIPS port in the early 90s. However, the company has been struggling with an increasingly lower market share and risked bankruptcy in recent years, ultimately leading to acquisition by start-up Wave Computing, which faced bankruptcy last year.

How this company was reborn just weeks ago, exiting the state of bankruptcy, is surprising, but not at all irrational: in its official statement, (the new) MIPS has become a member of RISC-V International, the non-profit organization managing the fully open-hardware ISA, substantially replacing their current architecture with the de facto open chip standard in its entirety. Licensing of the original MIPS architecture to third parties will probably be managed as before, so that the "old" architecture will remain available upon need. This is officially known as the "8th generation" of MIPS chips, indicating a total architectural gap from the previous seven iterations, essentially leaving the old architecture and fully embracing the new one. The Electronic Engineering Journal says it's likely that the new MIPS will continue to honor pre-existing licensing agreements, but it's unclear what level of support the company will offer for older MIPS-based chip designs.

An anonymous reader quotes a report from Reuters: Cyprus, Greece and Israel on Monday signed an initial agreement to build the world's longest and deepest underwater power cable that will traverse the Mediterranean seabed at a cost of about $900 million and link their electricity grids. The project, called the Euro-Asia interconnector, will provide a back-up power source in times of emergency, said Israeli Energy Minister Yuval Steinitz, who was in Nicosia to sign a memorandum of understanding with his counterparts. Cypriot Energy Minister Natasa Pilides said it marked "a decisive step towards ending the island's energy isolation, and consequently, our dependence on heavy fuels."

The cable will have a capacity of 1,000-2,000 megawatts (MW) and is expected to be completed by 2024, according to Israel's energy ministry. With a length of about 1,500 km and a maximum depth of 2,700 meters, it will be the longest and deepest subsea electricity cable to have ever been constructed, it said. Calling the project a "2,000 mega-watt highway," Pilides said the first stage is expected to be operational within 2025. It will cover three sections of the Mediterranean: some 310 kilometers between Israel and Cyprus, about 900 kilometers between Cyprus and Crete, and about 310 additional kilometers between Crete and mainland Greece. Greek power grid operator IPTO has started construction of the Crete-mainland part, seen concluding by 2023. The Greek operator and Eurasia have been working closely to make sure the two cables link to each other efficiently, an IPTO official said. The European Union has recognized the cable as a "Project of Common Interest", categorizing it as a project it is willing to partly finance.

An anonymous reader quotes a report from Bloomberg: Elon Musk is getting into the Texas power market, with previously unrevealed construction of a gigantic battery connected to an ailing electric grid that nearly collapsed last month. The move marks Tesla's first major foray into the epicenter of the U.S. energy economy. A Tesla subsidiary registered as Gambit Energy Storage LLC is quietly building a more than 100 megawatt energy storage project in Angleton, Texas, a town roughly 40 miles south of Houston. A battery that size could power about 20,000 homes on a hot summer day. Workers at the site kept equipment under cover and discouraged onlookers, but a Tesla logo could be seen on a worker's hard hat and public documents helped confirm the company's role. Property records on file with Brazoria County show Gambit shares the same address as a Tesla facility near the company's auto plant in Fremont, California. A filing with the U.S. Securities and Exchange Commission lists Gambit as a Tesla subsidiary. According to a document on the city of Angleton's website, the installation will use lithium iron phosphate batteries that are expected to last 10 to 20 years. The document says that it will generate around $1 million in property tax revenue for the city and the site will be unmanned but remotely monitored.

The kingdom is building a $5 billion plant to make green fuel for export and lessen the country's dependence on petrodollars. From a report: Sun-scorched expanses and steady Red Sea breezes make the northwest tip of Saudi Arabia prime real estate for what the kingdom hopes will become a global hub for green hydrogen. As governments and industries seek less-polluting alternatives to hydrocarbons, the world's biggest crude exporter doesn't want to cede the burgeoning hydrogen business to China, Europe or Australia and lose a potentially massive source of income. So it's building a $5 billion plant powered entirely by sun and wind that will be among the world's biggest green hydrogen makers when it opens in the planned megacity of Neom in 2025. The task of turning a patch of desert the size of Belgium into a metropolis powered by renewable energy falls to Peter Terium, the former chief executive officer of RWE AG, Germany's biggest utility, and clean-energy spinoff Innogy SE. His performance will help determine whether a country dependent on petrodollars can transition into a supplier of non-polluting fuels.

"There's nothing I've ever seen or heard of this dimension or challenge," Terium said. "I've been spending the last two years wrapping my mind around 'from scratch,' and now we're very much in execution mode." Hydrogen is morphing from a niche power source -- used in zeppelins, rockets and nuclear weapons == into big business, with the European Union alone committing $500 billion to scale up its infrastructure. Huge obstacles remain to the gas becoming a major part of the energy transition, and skeptics point to Saudi Arabia's weak track record so far capitalizing on what should be a competitive edge in the renewables business, especially solar, where there are many plans but few operational projects. But countries are jostling for position in a future global market, and hydrogen experts list the kingdom as one to watch.

The U.K. is hosting 10 projects to heat buildings with the gas, China is deploying fuel-cell buses and commercial vehicles, and Japan is planning to use the gas in steelmaking. U.S. presidential climate envoy John Kerry urged the domestic oil and gas industry to embrace hydrogen's "huge opportunities." That should mean plenty of potential customers for the plant called Helios Green Fuels. Saudi Arabia is setting its sights on becoming the world's largest supplier of hydrogen -- a market that BloombergNEF estimates could be worth as much as $700 billion by 2050. "You're seeing a more diversified portfolio of energy exports that is more resilient," said Shihab Elborai, a Dubai-based partner at consultant Strategy&. "It's diversified against any uncertainties in the rate and timing of the energy transition." Blueprints are being drawn and strategies are being announced, but it's still early days for the industry. Hydrogen is expensive to make without expelling greenhouse gases, difficult to store and highly combustible. Green hydrogen is produced by using renewable energy rather than fossil fuels. The current cost of producing a kilogram is a little under $5, according to the International Renewable Energy Agency.

"At the recent tinyML Summit 2021, Raspberry Pi co-founder Eben Upton teased the future of 'Pi Silicon'," writes Tom's Hardware, adding "It looks like machine learning could see a massive improvement thanks to Raspberry Pi's news in-house chip development team..." Raspberry Pi's in-house application specific integrated circuit team are working on the next iteration, and seems to be focused on lightweight accelerators for ultra low power machine learning applications. During Upton's talk at 40 minutes the slide changes and we see "Future Directions," a slide that shows three current generation 'Pi Silicon' boards, two of which are from board partners, SparkFun's MicroMod RP2040 and Arduino's Nano RP2040 Connect. The third is from ArduCam and they are working on the ArduCam Pico4ML which incorporates machine learning, camera, microphone and screen into a the Pico package.

The last bullet point hints at what the future silicon could be. It may come in the form of lightweight accelerators possibly 4-8 multiply-accumulates (MACs) per clock cycle.

Qbertino writes: Heise.de, a German tech news publisher, reports that wind has replaced coal as the main source of power in Germany. From the report: "The share of renewable energies in the amount of electricity generated and fed into the grid domestically rose from 42.3 percent in 2019 to 47.0 percent last year. At 25.6 percent, wind power was the first renewable energy source to have the highest share of the amount of electricity fed into the grid in a given year, replacing coal as the most important energy source. In 2020, 5.4 percent more electricity was generated from wind power than in 2019, when the share had been 22.8 percent..." (Sidenote: Paragraph translated by deepL in seconds; [I] find it quite feasible as a German and English native speaker. Color me impressed.)

This is not much to brag about yet because Coal is still buffering large parts of the nuclear fission exit Germany is doing, but it's a good milestone. By and large, the article concludes that Germany's exit from nuclear fission is going in the right direction.

States like Pennsylvania, Virginia, Idaho, Florida and Wisconsin have granted sidewalk robots legal rights as "pedestrians." Axios reports: In Pennsylvania, robot "pedestrians" can weigh up to 550 pounds and drive up to 12 mph. "Opposition has largely come from pedestrian and accessibility advocates, as well as labor unions like the Teamsters," per the Pittsburgh City Paper. The laws are a boon to Amazon's Scout delivery robot and FedEx's Roxo, which are being tested in urban and suburban settings. "Backers say the laws will usher in a future where household items show up in a matter of hours, with fewer idling delivery vans blocking traffic and spewing emissions," per Wired.

Some technology evangelists think these laws are a spectacularly bad idea. The National Association of City Transportation Officials -- NACTO -- says the robots "should be severely restricted if not banned outright." "Uncoordinated autonomous delivery services could flood sidewalks with bots, making walking increasingly difficult and unpleasant," NACTO says in a report. "Drone delivery could significantly increase noise pollution and add a new dimension of chaos to urban streets."

FrankOVD shares a report from TechCrunch: [F]irms backed by Robert Downey Jr. and Bill Gates are joining investors like Amazon and iPod inventor Tony Fadell to pour money into a company called Turntide Technologies that believes it has the next great innovation in the world's efforts to slow global climate change -- a better electric motor. The operation of buildings is responsible for 40% of CO2 emissions worldwide, Turntide noted in a statement. And, according to the U.S. Department of Energy (DOE), one-third of energy used in commercial buildings is wasted. Smart building technology adds an intelligent layer to eliminate this waste and inefficiency by automatically controlling lighting, air conditioning, heating, ventilation and other essential systems and Turntide's electric motors can add additional savings.

Turntide's basic innovation is a software-controlled motor, or switch reluctance motor, that uses precise pulses of energy instead of a constant flow of electricity. "In a conventional motor you are continuously driving current into the motor whatever speed you want to run it at," [CEO Ryan Morris] said. "We're pulsing in precise amounts of current just at the times when you need the torque... It's software-defined hardware."

He estimates that the technology is applicable to 95% of where electric motors are used today, but the initial focus will be on smart buildings because it's the easiest place to start and can have some of the largest immediate impact on energy usage. "The carbon impact of what we're doing is pretty massive," Morris told me last year. "The average energy reduction [in buildings] has been a 64% reduction. If we can replace all the motors in buildings in the U.S. that's the carbon equivalent of adding over 300 million tons of carbon sequestration per year."

According to Bloomberg, Nintendo is planning to unveil a model of its Switch gaming console equipped with a bigger Samsung OLED display and support for 4K. It's expected to arrive before Christmas. From the report: Samsung Display Co. will start mass production of 7-inch, 720p-resolution OLED panels as early as June with an initial monthly target of just under a million units. The displays are slated for shipment to assemblers around July. The gaming community has speculated online about the introduction of an OLED or organic light-emitting diode screen, but Nintendo has stayed mum and President Shuntaro Furukawa said in February his company has no plans to announce a new Switch "anytime soon." Samsung's involvement is the strongest indication that Nintendo is serious about updating the console, and on a large scale.

Nintendo decided to go with rigid OLED panels for the new model, the people said, a cheaper but less flexible alternative to the type commonly used for high-end smartphones. The latest model will also come with 4K ultra-high definition graphics when paired with TVs, they said. That could intensify a longstanding complaint of developers, who have struggled with the difference in resolution between handheld and TV modes and now face a bigger gap between the two.

An anonymous reader quotes a report from Ars Technica: US President Joe Biden has made the shift to electric vehicles an early focus of his administration. Days after his inauguration, he vowed to replace hundreds of thousands of federal civilian vehicles with electric versions. On Tuesday, Biden held a virtual meeting with CEOs from companies building charging infrastructure. The administration has set a goal to build more than 500,000 new electric vehicle charging stations by 2030.

Also on Tuesday, a coalition of six electric utilities announced a new initiative that will help Biden achieve his goal. The companies are planning to build a "seamless network of charging stations" in and around the American South. The group plans to build chargers near major highways in every southern state, stretching as far west as Texas and as far north as Indiana, Ohio, and Virginia. This is not a joint venture. Each utility will build and run its own charging stations. But the goal is to make them appear to the customer as a unified network.
