Breakthrough discovery in light interactions with nanoparticles paves the way for advances in optical computing
https://phys.org/news/2022-02-breakthro ... paves.html
by CUNY Advanced Science Research Center
Computers are an indispensable part of our daily lives, and the need for ones that can work faster, solve complex problems more efficiently, and leave smaller environmental footprints by minimizing the required energy for computation is increasingly urgent. Recent progress in photonics has shown that it's possible to achieve more efficient computing through optical devices that use interactions between metamaterials and light waves to apply mathematical operations of interest on the input signals, and even solve complex mathematical problems. But to date, such computers have required a large footprint and precise, large-area fabrication of the components, which, because of their size, are difficult to scale into more complex networks.

A newly published paper in Physical Review Letters from researchers at the Advanced Science Research Center at the CUNY Graduate Center (CUNY ASRC) details a breakthrough discovery in nanomaterials and light-wave interactions that paves the way for development of small, low-energy optical computers capable of advanced computing.

Elon Musk’s Starlink Becomes Most-Downloaded App In Ukraine
Starlink, the app that enables mobile users to access SpaceX’s satellite internet service of the same name, was the most-downloaded app in Ukraine Monday afternoon after reaching the top spot Sunday, according to data seen by the Wall Street Journal, following SpaceX CEO Elon Musk’s rapid delivery of the terminals that provide the service to the war-torn country last month.
And what's interesting is that they are apparently able to get 200Mbps download speeds there. People in a war zone have better internet than I do!

And they're using it to transact in cryptocurrencies. Ever since Starlink was sent to Ukraine, demand for Bitcoin and other crypto shot up.
To know is essentially the same as not knowing. The only thing that occurs is the rearrangement of atoms in your brain.

New technique offers faster security for non-volatile memory tech
https://techxplore.com/news/2022-04-tec ... -tech.html
by Matt Shipman, North Carolina State University

Researchers have developed a technique that leverages hardware and software to improve file system security for next-generation memory technologies called non-volatile memories (NVMs). The new encryption technique also permits faster performance than existing software security technologies.

"NVMs are an emerging technology that allows rapid access to the data, and retains data even when a system crashes or loses power," says Amro Awad, senior author of a paper on the work and an assistant professor of electrical and computer engineering at North Carolina State University. "However, the features that give NVMs these attractive characteristics also make it difficult to encrypt files on NVM devices—which raises security concerns. We've developed a way to secure files on NVM devices without sacrificing the speed that makes NVMs attractive."

"Our technique allows for file-level encryption in fast NVM memories, while cutting the related execution time significantly," says Kazi Abu Zubair, first author of the paper and a Ph.D. student at NC State.

Traditionally, computers use two types of data storage. Dynamic random access memory (DRAM) allows quick access to stored data, but will lose that data if the system crashes. Long-term storage technologies, such as hard drives, are good at retaining data even if a system loses power—but store the data in a way that makes it slower to access.

NVMs combine the best features of both technologies. However, securing files on NVM devices can be challenging.

Cloud server leasing can leave sensitive data up for grabs

by Pennsylvania State University
https://techxplore.com/news/2022-04-clo ... itive.html
Renting space and IP addresses on a public server has become standard business practice, but according to a team of Penn State computer scientists, current industry practices can lead to "cloud squatting," which can create a security risk, endangering sensitive customer and organization data intended to remain private.

Cloud squatting occurs when a company, such as your bank, leases space and IP addresses—unique addresses that identify individual computers or computer networks—on a public server, uses them, and then releases the space and addresses back to the public server company, a standard pattern seen every day. The public server company, such as Amazon, Google, or Microsoft, then assigns the same addresses to a second company.  If this second company is a bad actor, it can receive information coming into the address intended for the original company—for example, when you as a customer unknowingly use an outdated link when interacting with your bank—and use it to its advantage—cloud squatting.

China Further Limits Access to Unauthorized Foreign Games
by Rita Liao
April 15, 2022

https://techcrunch.com/2022/04/15/china ... ign-games/

Introduction:
(TechCrunch) For years, China has left a loophole open for people to access unauthorized video games, but it’s ready to close it.

Many foreign titles lack a Chinese publishing partner like Tencent to help them obtain the government-issued license needed to operate in the country, so players normally rely on an “accelerator” to reduce delays of overseas-hosted games.

On Wednesday, Tencent, the world’s largest online gaming company, announced it will terminate its gaming booster that allows users to play overseas games. Though not explicitly said in the notice, some users see the decision as the authorities’ stepping up to limit access to foreign gameplay. Tencent’s rival NetEase also runs a similar service, which is still operating.

The other signal of enhanced control came on Friday when China’s National Radio and Television Administration, the regulator granting video games licenses, said platforms will be “strictly prohibited” from livestreaming games that have not been authorized by the government. Platforms, including their individual and business accounts, should gain approval before broadcasting overseas games or matches, the notice said.

This will substantially shrink the number of games that China’s livestreaming hosts can discuss, which could put many of them out of work, as China has slowed down the approval process for new games over the last few years. Many foreign titles may not be officially available in China, but a big market exists where commentary and matches of blockbuster international games are featured on the country’s live broadcasting platforms like Huya and Douyu.

TSMC: 2nm Chips Arriving in 2026
When Taiwan Semiconductor Manufacturing Company first confirmed the development of its N2 (2 nm-class) fabrication process in 2020, it did not disclose many details about the node or say when it intends it was set to enter production. This week, the company confirmed that the technology relies on a new transistor structure, but chips that use it won't become available until 2026.

N2 on Track for HVM in H2 2025
C.C. Wei, chief executive of TSMC, this week formally confirmed that the company's N2 node will, as expected, rely on gate-all-around (GAA) transistors (though he did not elaborate on details or reveal the marketing name of the architecture). The fabrication process will continue to rely on existing extreme ultraviolet (EUV) lithography, with a 0.33 numerical aperture.

The technology is expected to be ready for risk production sometime at the end of 2024 and for high-volume manufacturing (HVM) toward the end of 2025. This means that TSMC's customers should receive their first N2-based chips in 2026.
