Researchers at Texas A&M have come up with a novel way for touchscreens to feel more than just perfectly smooth by fooling a user's sense of touch through temperature changes. Gizmodo reports: In a recently published paper in the Science Robotics journal, they found that by regulating the temperature of the surface of a touchscreen, they can increase or decrease the amount of friction a finger feels like it's experiencing. The sensation of friction can be increased by as much as 50% by increasing a touchscreen's surface temperature from 23 degrees Celsius to 42 degrees Celsius, while the actual temperature changes are imperceptible to the user, assuming they're sticking to taps or quick swipe gestures on the screen.

The current prototypes don't facilitate temperature adjustments in fine detail, but the eventual goal is to be able to manipulate and quickly change the temperature on any region of a touchscreen so that as a finger is sliding across it the changes in friction that are felt fool the brain into thinking it's feeling physical buttons like keyboards, playback controls, even joysticks and action buttons for gaming.

Google appears to have built its own solution for running Windows games on Stadia. Google is planning to detail its Windows "emulator" for Linux next week at the company's Google for Games Developer Summit on March 15th. From a report: Reddit users have spotted a session at the summit that will detail "how to write a Windows emulator for Linux from scratch." The session will be led by Marcin Undak, on Google's Stadia porting platform team, and promises a "detailed overview of the technology behind Google's solution for running unmodified Windows games on Stadia." It appears that Google has built its own Windows emulator for Linux to help developers port games to the service without having to modify titles for Linux. If the emulator runs live on Stadia instead of just testing environments, this could open the door to a lot more games making their way to Stadia in the future

Russians are rapidly turning to internet services that cloak their location to help bypass restrictions on accessing foreign social media and news sites. From a report: Providers of virtual private networks, or VPNs, are recording a surge in usage from Russia after the Kremlin cracked down on Facebook and other services as part of a broader effort to silence dissent and limit information about its invasion of Ukraine. "In the past week, we saw traffic to our website from Russia increase by around 330% week over week," Harold Li, vice president of ExpressVPN, said in an email to Bloomberg on Wednesday. As of Tuesday, Russian interest in VPNs was more than eight times pre-invasion levels, according to data gathered by Top10VPN. Usage peaked at more than 10 times on March 5, the day after Facebook and Twitter were blocked by Russian authorities.

The Georgia state Senate voted 33-21 on Tuesday to pass a bill that seeks to prohibit social media platforms from removing or censoring content amid an outcry from conservatives that their political views are being discriminated against, even though a similar Texas law has been put on hold by a federal court. The Associated Press reports: Senate Bill 393 moves to the House for more debate. It declares that social media companies that have more than 20 million users in the United States are common carriers and that they can't block people from receiving certain messages based on viewpoints, location, race, ethnicity, religion, political beliefs, gender, sexual orientation or disability. "What we are stating here is you cannot be discriminated against for your viewpoint, your gender, your age or other things in this 21st century public square," said Sen. Greg Dolezal, a Cumming Republican who is sponsoring the bill. Dolezal said companies could still pull down lewd, obscene or offensive materials.

But the technology industry says the measure is illegal, in part because it would unconstitutionally make private companies host speech they don't agree with. They also argue that private owners should be able to do as they please with their own property. Dolezal has acknowledged that the state would be sued if it passed the law, but argues that a challenge could be heard by the U.S. Supreme Court, breaking new and desirable ground. Researchers have not found widespread evidence that social media companies are biased against conservative news, posts or materials.

The bill says social media companies must publish how it moderates content, targets content to specific users, and how it boosts the reach or hides specific content. It also says social media companies have to publish a report every six months on how often they were alerted to potentially illegal content and how many times they removed or downplayed content and suspended or removed users. Anyone who doesn't think a company is following the law could file a civil lawsuit, including a class action, in Georgia courts.

Lumen Technologies, an American company that operates one of the largest Internet backbones and carries a significant percentage of the world's Internet traffic, said today it will stop routing traffic for organizations based in Russia. KrebsOnSecurity reports: Lumen's decision comes just days after a similar exit by backbone provider Cogent, and amid a news media crackdown in Russia that has already left millions of Russians in the dark about what is really going on with their president's war in Ukraine. Monroe, La. based Lumen (formerly CenturyLink) initially said it would halt all new business with organizations based in Russia, leaving open the possibility of continuing to serve existing clients there. But on Tuesday the company said it could no longer justify that stance.

"Life has taken a turn in Russia and Lumen is unable to continue to operate in this market," Lumen said in a published statement. "The business services we provide are extremely small and very limited as is our physical presence. However, we are taking steps to immediately stop business in the region." "We decided to disconnect the network due to increased security risk inside Russia," the statement continues. "We have not yet experienced network disruptions but given the increasingly uncertain environment and the heightened risk of state action, we took this move to ensure the security of our and our customers' networks, as well as the ongoing integrity of the global Internet." According to Internet infrastructure monitoring firm Kentik, Lumen is the top international transit provider to Russia, with customers including Russian telecom giants Rostelecom and TTK, as well as all three major mobile operators (MTS, Megafon and VEON).

At its "Peek Performance" event, Apple today announced the third-generation iPhone SE, featuring the A15 Bionic chip, improved battery life, 5G connectivity, a new camera system, and more, all for a starting price of $429. MacRumors reports: The new iPhone SE features the same 4.7-inch display as the current model, but now offers the toughest glass in a smartphone on the front and back -- the same as on the back of the iPhone 13 and iPhone 13 Pro. The device's new 12MP Wide camera system offers a range of improvements and computational photography features including Deep Fusion, Photographic Styles, Portrait Mode, and Smart HDR 4.

The new iPhone SE contains the same A15 Bionic chip from the iPhone 13 and iPhone 13 Pro. [...] The A15 Bionic also gives the new iPhone SE longer battery life than the previous-generation and older 4.7-inch iPhone models despite having a compact form-factor and 5G connectivity. It continues to support fast charging and be compatible with Qi-certified chargers for wireless charging. Along with the new iPhone SE, Apple also unveiled the all-new Mac Studio and Studio Display, flagship M1 Ultra desktop processor, and updated iPad Air.

Laptops and smartphones made by Apple, Microsoft, and Google are considerably less repair-friendly than those made by competitors Asus, Dell, and Motorola, according to a new report. From a report: These findings may be unsurprising to people who like to fix gadgets, but the data to back them up comes from an unusual source: the companies themselves. The report, released today by the US Public Research Interest Group's Education Fund, draws on data companies are now releasing in France to comply with the government's world-first "repairability index" law, which went into effect last year. The law requires manufacturers of certain electronic devices, including cell phones and laptops, to score each of their products based on how easily repairable it is and make that score, along with the data that went into it, available to consumers at point-of-sale.

Google has confirmed plans to acquire cybersecurity company Mandiant in an all-cash deal worth $5.4 billion. From a report: The move comes exactly a month after reports emerged that Microsoft was in early discussions to buy Mandiant, meaning that Google is essentially getting one over its big cloud rival. Mandiant works with customers including InfoSys, OlyFed, and the Bank of Thailand, providing threat intelligence and consulting services, and automated tools for investigating security alerts. Mandiant is perhaps better known under its former name FireEye, a U.S. cybersecurity firm that shot to prominence for detecting major cyber attacks through the years. FireEye had acquired Mandiant for $1 billion in 2013, but last year it revealed plans to sell off the FireEye brand and products business and focus on its Mandiant cyber forensics business instead./i?

With sanctions against Russia starting to bite, the Kremlin is mulling ways to keep businesses and the government running. The latest is a creative twist on state asset seizures, only instead of the government taking over an oil refinery, for example, Russia is considering legalizing software piracy. Ars Technica reports: Russian law already allows for the government to authorize -- "without consent of the patent holder" -- the use of any intellectual property "in case of emergency related to ensuring the defense and security of the state." The government hasn't taken that step yet, but it may soon, according to a report from Russian business newspaper Kommersant, spotted and translated by Kyle Mitchell, an attorney who specializes in technology law. It's yet another sign of a Cyber Curtain that's increasingly separating Russia from the West.

The plan would create "a compulsory licensing mechanism for software, databases, and technology for integrated microcircuits," the Kommersant said. It would only apply to companies from countries that have imposed sanctions. While the article doesn't name names, many large Western firms -- some of which would be likely targets -- have drastically scaled back business in Russia. So far, Microsoft has suspended sales of new products and services in Russia, Apple has stopped selling devices, and Samsung has stopped selling both devices and chips. Presumably, any move by the Kremlin to "seize" IP would exempt Chinese companies, which are reportedly considering how to press their advantage. Smartphone-makers Xiaomi and Honor stand to gain, as do Chinese automakers. Still, any gains aren't guaranteed since doing business in Russia has become riddled with problems, spanning everything from logistics to finance.

A research center housing a nuclear neutron source facility held at the Kharkiv Institute of Physics and Technology in eastern Ukraine was hit by Russian forces on Sunday, per a report from the state nuclear inspectorate. Motherboard reports: In a release published Sunday evening, the inspectorate called the blast "nuclear terrorism," spelling out a list of damages: a substation, which connects the plant to the electrical grid, on which the plant runs; cables within the facility's cooling system, which effectively prevent the plant from a meltdown; a heating line between structures in the facility; surface damages to the building that houses the structure; and windows across a number of buildings within the installation. "This list of damages is not complete so far. Currently, information on the consequences of the damages is being specified by the personnel," the report reads. An updated report following further inspection located no additional damage this morning.

The Security Service of Ukraine's Kharkiv branch said destruction of the facility could lead to "environmental disaster," the Kyiv Independent reported Sunday. Russian state-owned news agency TASS reported Sunday that the attacks were in fact brought on by Ukraine, a line that has since been debunked. The reactor, known as the NSA "Neutron Source" was built with support from the Illinois-based Argonne National Laboratory in service of an agreement signed between the U.S. and Ukraine at the 2010 Nuclear Security Summit in Washington, D.C. The U.S. invested $73 million in the project, which promised that the Kharkiv Institute of Physics and Technology would be "given the opportunity to build state-of-the-art technology in nuclear research that will contribute to "solving problems of nuclear power industry and extending technical lifetime of nuclear power plants,'" according to a report from the European Union Non-Proliferation Consortium.

The British government has asked its nuclear regulator to start the process for approving Rolls-Royce's planned small- scale modular nuclear reactor, which policymakers hope will help cut dependence on fossil fuels and lower carbon emissions. From a report: Britain last year backed a $546 million funding round at the company to develop the country's first small modular nuclear reactor (SMR), part of its drive to reach net zero carbon emissions and promote new technology with export potential. Energy minister Kwasi Kwarteng has also said new nuclear projects will play an important part in Britain's efforts to reduce its reliance on expensive gas, which hit fresh record high prices on Monday amid the crisis in Ukraine. SMRs can be made in factories, with parts small enough to be transported on trucks and barges and assembled more quickly and cheaply than large-scale reactors. Each mini plant can power around one million homes and Rolls-Royce has forecast the SMR business could create up to 40,000 jobs based on British and export demand.

The Environmental Protection Agency (EPA) on Monday said it was proposing new rules to cut smog-forming and greenhouse gas emissions from heavy duty vehicles. From a report: The agency is proposing to require cuts in nitrogen oxide emissions from heavy trucks of 47 percent to 60 percent by 2045. The new standards would begin in the 2027 model year. Separately, the Transportation Department is announcing nearly $1.5 billion in funding for 2022 to help state and local governments purchase U.S.-built electric transit buses and low-emission models. The department is also announcing $2.2 billion in funding to 35 transit agencies across 18 states. The EPA is also proposing stricter new greenhouse gas emissions standards for some types of heavy vehicles.

In mid-February, hackers gained access to computers belonging to current and former employees at nearly two dozen major natural gas suppliers and exporters, including Chevron, Cheniere Energy and Kinder Morgan, according to research shared exclusively with Bloomberg News. From the report: The attacks targeted companies involved with the production of liquefied natural gas, or LNG, and they were the first stage in an effort to infiltrate an increasingly critical sector of the energy industry, according to Gene Yoo, chief executive officer of Los Angeles-based Resecurity, which discovered the operation. They occurred on the eve of Russia's invasion of Ukraine, when energy markets were already roiled by tight supplies.

Resecurity's investigation began last month when the firm's researchers spotted a small number of hackers, including one linked to a wave of attacks in 2018 against European organizations that Microsoft attributed to Strontium, the company's nickname for a hacking group associated with Russia's GRU military intelligence service. The hackers were looking to pay top dollar on the dark web for access to personal computers belonging to workers at large natural gas companies in the U.S., which were used as a back door into company networks, Yoo said. The researchers located the hackers' servers and found a vulnerability in the software, which allowed them to obtain files from the machines and see what the attackers had already done, Yoo said.

Consumers will still be able to use Mastercard and Visa-branded cards for domestic transactions in Russia, the country's state-backed payments network has said, reducing the impact of the US firms' decision to pull services over the invasion of Ukraine. From a report: Russia's homegrown payments system Mir said the cardholders would still be able to access their funds, make withdrawals and domestic transfers -- at least until their bank cards expire. Mir has processed most domestic payments in Russia since 2015, while foreign operators such as Visa and Mastercard continued to run international transactions. The operator -- which is 100% owned by the country's central bank -- was established on government orders to protect the economy against sanctions imposed over Moscow's annexation of Crimea in 2014.

"All cards of these payment systems already issued by Russian banks will continue to work within our country as before," Mir's operator said in the early hours of Sunday. "Until the expiration of their validity, Visa and Mastercard cardholders have access to all the funds on their accounts, as well as all the usual payment transactions -- paying for purchases, transferring funds from card to card, withdrawing cash, etc." Further reading: Visa Discloses Russia, Ukraine Exposure.

An anonymous reader shares a report: If blockchain technology is to reach true mass adoption, it will have to become cheaper and more efficient. Low transaction throughput on some of the most popular blockchains, most notably Ethereum, has kept gas fees high and hindered scalability. A host of new projects has cropped up to improve efficiency in the blockchain space, each with its own set of tradeoffs, including proof-of-capacity blockchain Subspace, which announced its $32.9 million Series A last week. Now, a team of researchers from Stanford University's applied cryptography research group has entered the fray. The team is coming out of stealth mode with Espresso, a new layer one blockchain they are building to allow for higher throughput and lower gas fees while prioritizing user privacy and decentralization. Espresso aims to optimize for both privacy and scalability by leveraging zero-knowledge proofs, a cryptographic tool that allows a party to prove a statement is true without revealing the evidence behind that statement, CEO Ben Fisch told TechCrunch in an interview.

Espresso Systems, the company behind the blockchain project, is led by Fisch, chief operating officer Charles Lu, and chief scientist Benedikt Banz, collaborators at Stanford who have each worked on other high-profile web3 projects, including the anonymity-focused Monero blockchain and BitTorrent co-founder Bram Cohen's Chia. They've teamed up with chief strategy officer Jill Gunter, a former crypto investor at Slow Ventures who is the fourth Espresso Systems co-founder, to take their blockchain and associated products to market. To achieve greater throughput, Espresso uses ZK-Rollups, a solution based on zero-knowledge proofs that allow transactions to be processed off-chain. ZK-Rollups consolidate multiple transactions into a single, easily-verifiable proof, thus reducing the bandwidth and computational load on the consensus protocol. The method has already gained popularity on the Ethereum blockchain through scaling solution providers like StarkWare and zkSync, according to Fisch.

Samsung on Monday confirmed that the company recently suffered a cyberattack, but said that it doesn't anticipate any impact on its business or customers. From a report: Last week, South American hacking group Lapsus$ claimed it had stolen 190GB of confidential data, including source code, from the South Korean tech giant's servers. The group also posted snapshots of the alleged data online. Samsung has now confirmed in a statement, without naming the hacking group, that there was a security breach, but it asserted that no personal information of customers was compromised.

CNBC reminds us that Ukraine is also home "to a massive community of software developers who work remotely for companies all over the U.S. and Europe.

"There were 200,000 Ukrainian developers in the country in 2020, according to Amsterdam-based software development outsourcing company Daxx, which says that 20% of Fortune 500 companies have their remote development teams in Ukraine." As major cities across Ukraine endure devastating attacks that have seen buildings reduced to rubble, company leaders in the U.S. and Europe have expressed awe at their Ukraine-based staff. Those developers, along with other Ukrainian civilians in the country, are now being forced to defend their homes and cities while sheltering from Russian bombs. But many are still continuing to remotely work for their employers, supporting the local defense effort by day while sending in their deliverables by night.

"Yes our teams are sending deliverables from a f — ing parking garage in Kharkiv under heavy shelling and gunfire in the area. Amazing humans," Logan Bender, chief financial officer at a San Francisco-based software licensing company, said in a story posted to Instagram on Tuesday by venture capital meme account PrayingforExits. "We of course told them all deliverables are off the table. Nothing of you expected other than to let us know how we can help other than wiring money and getting their visa process going," he said. Bender has been working to get a defense service to extract his employees from the conflict zone under armed guards....

"Our lead front-end developer fled to Lviv to his parents' rural house 40km outside the city and is still submitting pull requests," Eric Hovagim, CEO and founder of Los Angeles-based betting platform Pogbet, told CNBC. "He's returning to Lviv tomorrow morning to continue his work while helping with the fight."

"These Ukrainians are built different," Hovagim said. "No armed guard extraction necessary. These people are their own armed guards...."

Ukrainians in IT-related fields are also deploying their skills for the fight at home. Employees at a local digital marketing agency in Kyiv are helping carry out cyberattacks against Russian entities in collaboration with Ukraine's Ministry of Digital Transformation. A local Telegram channel dedicated to crowd-sourcing programmers to carry out cyberattacks against Russia has nearly a million subscribers...

Alexandru Asimionese, co-founder of Moldova-based software developer Labs42, described one of his freelance designers based in the northwestern Ukrainian city of Lutsk. "In the morning goes to buy high-protein snacks to deliver to the local army. Late night, sends logo ideas. Always paid in crypto (via) Binance," he said. Another start-up manager said that his Ukrainian girlfriend was returning to Ukraine from overseas to fight, and plans to continue working for her tech company while not fighting invaders.

"Staff at Ukraine's Zaporizhzhia nuclear power plant are being told what to do by the Russian military commander who seized the site last week, in violation of international safety protocols," reports the Guardian: The International Atomic Energy Agency (IAEA) expressed "grave concern" at the situation at the six-reactor plant, the largest in Europe. The agency was told by the Ukrainian nuclear regulator that "any action of plant management — including measures related to the technical operation of the six reactor units — requires prior approval by the Russian commander". The IAEA director general, Rafael Mariano Grossi, said on Sunday that the Russian military command over the nuclear plant "contravenes one of the seven indispensable pillars of nuclear safety and security" which states that the operating staff must be able to carry out their safety and security duties and be able to make decisions "free of undue pressure".

Russian forces shelled the Zaporizhzhia plant in the early hours of Friday morning, damaging a walkway between two of the six reactors, and starting a fire in a nearby building used for training. As a result some of the reactors were shut down and others were put on low power. The reactors themselves are well protected by a thick concrete shell, but there is concern that more vulnerable spent fuel rods could be hit, or that the power and cooling systems could be affected, potentially triggering a meltdown....

The IAEA said that the operators at the plant were now being able to rotate between three shifts, relieving the operators who had been on duty at the time the plant was seized, but there were still "problems with availability and supply of food" which the Ukrainian regulator said was affecting morale on the plant.

"The events of recent days have taken us away from the stable and predictable development of mankind," argue two Moscow-based technology professors in Communications of the ACM, citing anticipated shortages of high-performance processors. But fortunately, they have a partial workarond...

One of the professors — Andrei Sukhov of HSE University in Moscow — explained their idea to the Register: In a timely piece Sukhov explains how Russian computer science teams are looking at building the next generation of clusters using older clustering technologies and a slew of open-source software for managing everything from code portability to parallelization as well as standards including PCIe 3.0, USB 4, and even existing Russian knock-off buses inspired by Infiniband (Angara ES8430).... While all the pieces might be in place, there is still the need to manufacture new boards, a problem Sukhov said can be routed around by using wireless protocols as the switching mechanism between processors, even though the network latency hit will be subpar, making it difficult to do any true tightly coupled, low-latency HPC simulations (which come in handy in areas like nuclear weapons simulations, as just one example).

"Given that the available mobile systems-on-chip are on the order of 100 Gflops, performance of several teraflops for small clusters of high-performance systems-on-chip is quite achievable," Sukhov added. "The use of standard open operating systems, such as Linux, will greatly facilitate the use of custom applications and allow such systems to run in the near future. It is possible that such clusters can be heterogeneous, including different systems-on-chip for different tasks (or, for example, FPGAs to create specialized on-the-fly configurable accelerators for specific tasks)...."

As he told The Register in a short exchange following the article, "Naturally, it will be impossible to make a new supercomputer in Russia in the coming years. Nevertheless, it is quite possible to close all the current needs in computing and data processing using the approach we have proposed. Especially if we apply hardware acceleration to tasks, depending on their type," he adds.... "During this implementation, software solutions and new protocols for data exchange, as well as computing technologies, will be worked out."
As for Russia's existing supercomputers, "no special problems are foreseen," Sukhov added. "These supercomputers are based on Linux and can continue to operate without the support of the companies that supplied the hardware and software."

"In better times, Ukrainian drone enthusiasts flew their gadgets into the sky to photograph weddings, fertilize soybean fields or race other drones for fun," writes the Associated Press.

"Now some are risking their lives by forming a volunteer drone force to help their country repel the Russian invasion." "Kyiv needs you and your drone at this moment of fury!" read a Facebook post late last week from the Ukrainian military, calling for citizens to donate hobby drones and to volunteer as experienced pilots to operate them. One entrepreneur who runs a retail store selling consumer drones in the capital said its entire stock of some 300 drones made by Chinese company DJI has been dispersed for the cause. Others are working to get more drones across the border from friends and colleagues in Poland and elsewhere in Europe....

Unlike the much larger Turkish-built combat drones that Ukraine has in its arsenal, off-the-shelf consumer drones aren't much use as weapons — but they can be powerful reconnaissance tools. Civilians have been using the aerial cameras to track Russian convoys and then relay the images and GPS coordinates to Ukrainian troops. Some of the machines have night vision and heat sensors.... They can also be used to assist search-and-rescue operations....

Small civilian drones are no match against Russian combat power but will likely become increasingly important in a protracted war...
The Associated Press points out there's now more than 15,000 members in one drone-focused Facebook group "who have been trading tips about how to assist Ukrainian troops." The operations chief for a Kyiv-based drone company tells the Associated Press, "Now in Ukraine no one remains indifferent. Everyone does what they can."
