New ‘Spray-On’ Memory Could Turn Everyday Items Into Digital Storage Devices

Researchers at Duke University have developed “spray-on” digital memory using only an aerosol jet printer and nanoparticle inks. An anonymous reader quotes Duke Today: The device, which is analogous to a 4-bit flash drive, is the first fully-printed digital memory that would be suitable for practical use in simple electronics such as environmental sensors or RFID tags. And because it is jet-printed at relatively low temperatures, it could be used to build programmable electronic devices on bendable materials like paper, plastic or fabric… The new material, made of silica-coated copper nanowires encased in a polymer matrix, encodes information not in states of charge but instead in states of resistance. By applying a small voltage, it can be switched between a state of high resistance, which stops electric current, and a state of low resistance, which allows current to flow. And, unlike silicon, the nanowires and the polymer can be dissolved in methanol, creating a liquid that can be sprayed through the nozzle of a printer. Amazingly, its write speed is three microseconds, “rivaling the speed of flash drives.” The information can be re-written many times, and the stored data can last for up to 10 years.

Toshiba Plans To Ship a 1TB Flash Chip To Manufacturers This Spring

Lucas123 writes: Toshiba has begun shipping samples of its third-generation 3D NAND memory product, a chip with 64 stacked flash cells that it said will enable a 1TB chip shipping later this spring. The new flash memory product has 65% greater capacity than the previous generation technology, which used 48 layers of NAND flash cells. The chip will be used in data centers and consumer SSD products. The technology announcement comes even as suitors are eyeing buying a majority share of the company’s memory business. Along with a previous report about Western Digital, Foxxcon, SK Hynix and Micron Technology have now also thrown their hats in the ring to purchase a majority share in Toshiba’s memory spin-off, according to a new report in the Nikkei’s Asian Review.

MAME Celebrates Its 20th Anniversary

After years of work, a fan has finally completed a MAME version of Atari’s unreleased game Primal Rage II this week, one more example of the emulator preserving digital history. Long-time Slashdot reader AmiMoJo quotes MAME.net: Way back in 1997, Nicola Salmoria merged a few stand-alone arcade machine emulators into the first Multiple Arcade Machine Emulator. Could he have possibly imagined the significance of what he’d built? Over the past two decades, MAME has brought together over a thousand contributors to build a system that emulates more machines than any other program. But MAME is more than that: MAME represents the idea that our digital heritage is important and should be preserved for future generations. MAME strives to accurately represent original systems, allowing unmodified software to run as intended. Today, MAME documents over thirty thousand systems, and usably emulates over ten thousand. MAME meets the definitions of Open Source and Free Software, and works with Windows, macOS, Linux and BSD running on any CPU from x86-64 to ARM to IBM zSeries. A 20th-anniversary blog post thanked MAME’s 1, 600 contributors — more than triple the number after its 10th anniversary — and also thanks MAME’s uncredited contributors. “if you’ve filed a bug report, distributed binaries, run a community site, or just put in a good word for MAME, we appreciate it.” I’ve seen MAME resurrect everything from a rare East German arcade game to a Sonic the Hedgehog popcorn machine. Anybody else have a favorite MAME experience to share? Read more of this story at Slashdot.

Analysis: PS4 Pro’s “Boost Mode” bumps frame rates up to 38 percent

This Digital Foundry video goes into detail about the PS4 Pro’s Boost Mode improvements on many games. Earlier this week, we were surprised by reports that the new Version 4.5 beta firmware for the PlayStation 4 Pro offered an unannounced “Boost Mode”  promising “improved gameplay, including higher frame rates, for some games that were released before the introduction of PS4 Pro.” The folks over at the excellent Digital Foundry have now put that new mode through its paces , finding frame rate increases of up to 38 percent on unpatched PS4 games. Those frame rate improvements are very dependent on the specific title in question, though. Destiny for instance, is locked to 30fps in its code, and thus gets no benefit from Boost Mode. An intensive online shooter like Battlefield 4 , on the other hand, can stay at a solid 60fps in Boost Mode, without the frequent frame-rate dips that can occur during a 64-player match in base mode. Many games seem to see the same modest 14 percent bump in their frame rates in Boost Mode. That coincidentally matches the 14 percent faster clock speed that the PS4 Pro’s GPU has over the original system (911Mhz vs 800Mhz), suggesting that the additional processor cycles are helping on GPU-limited games. Boost Mode doesn’t seem to make any use of the 18 additional compute cores available in the PS4 Pro, however—for that, you need a game-specific patch to be coded by the developer.

Acer penalized $115k for leaving credit card info unprotected

It wasn’t nearly as bad as Yahoo leaking 500 million users’ data, but Acer had its own hacking scare last year. Back in June, the Taiwanese computer manufacturer admitted that somebody stole credit card information for nearly 35, 000 individuals who bought from the company’s online store. The electronics giant finally settled with the New York Attorney General’s office to the tune of $115, 000 in penalties along with an assurance to shore up their digital security. During their investigation, the attorney general’s office discovered that Acer’s technical support had made serious security errors. First, they left Acer’s e-commerce platform in debugging mode from July 2015 until April 2016. This setting stores all data transferred through the website in an unencrypted, plain-text log file. Then they misconfigured the company website to allow directory browsing by any unauthorized user. At least one hacking group noticed and stole data between November 2015 and April 2016. This amounted to leaked legal names, usernames and passwords, physical addresses and credit card numbers with verification codes for over 35, 000 individuals in the US, Canada and Puerto Rico. Thankfully, the haul didn’t include social security numbers, but it’s still a painful security snafu from a known computer brand. Source: New York Attorney General’s office

Bitcoin mining just became more difficult, on purpose

If you have computers chugging away as bitcoin mining machines , don’t be surprised if your output just fell through the floor. Reuters notes that code built into the digital currency system has cut the mining reward in half as of July 9th. Where there were previously 25 bitcoins (roughly $16, 000) to be mined every 10 minutes, you now have to fight over 12.5. The measure automatically kicks in every four years as part of an attempt to curb inflation that would come from both a growing number of miners and ever-faster computers. To no one’s surprise, reducing the reward could have serious consequences for dedicated miners. As you have to work twice as hard to get the same money, companies with not-so-efficient operations may have no choice but to restructure or even close shop entirely. KnCMiner , for instance, declared bankruptcy in May after warning about the impending profit loss. Those miners most likely to survive are the ones that keep costs to a minimum through lower-power computers and minimal staff. You’d think that the industry would have anticipated the halving given that it will happen every four years like clockwork, but that’s not necessarily the case. Although bitcoin isn’t quite as celebrated as it was a while back, it’s still far more mainstream than it was in 2012. There are many more people mining than there were four years ago, and not all of them realize that they’ll have to factor in those reward cuts. The bigger question is whether or not the bitcoin business will be better-prepared when 2020 rolls around. Miners will either have to trim costs yet again or hope that they can make money from transaction fees. Source: Reuters

4K copy protection removal shop settles for $5.2 million

Intel and Warner Bros. are still very much embroiled in a war on companies stripping copyright protection from 4K and Blu-ray videos. Hardware seller Ace Deal has agreed to pay the two industry giants $5.2 million to settle a lawsuit over alleged violations of the Digital Millennium Copyright Act. Supposedly, Ace Deal knowingly aided in piracy by selling devices that remove HDCP anti-copying measures, making it relatively easy to bootleg the latest 4K movie extravaganza . The shop has already pulled the offending gear from its online store and is barred from selling similar devices in the future, but the small outfit still faces a relatively big, potentially crippling payout. The verdict is a sharp contrast to what’s happening with LegendSky, which faced a similar lawsuit at the start of the year. It contends that its HDFury gadgets aren’t stripping HDCP, just weakening it (which is legal) — in fact, it counter-sued Intel and Warner Bros. for allegedly making defamatory claims and abusing their market position. Ace Deal didn’t have that defense, so it was far more likely to be on the hook. Source: TorrentFreak
