Iran Unveils 'Quantum' Device That Anyone Can Buy for $589 on Amazon (vice.com) 67

What Iran's military called "the first product of the quantum processing algorithm" of the Naval university appears to be a stock development board, available widely online for around $600. Motherboard reports: According to multiple state-linked news agencies in Iran, the computer will help Iran detect disturbances on the surface of water using algorithms. Iranian Rear Admiral Habibollah Sayyari showed off the board during the ceremony and spoke of Iran's recent breakthroughs in the world of quantum technology. The touted quantum device appears to be a development board manufactured by a company called Diligent. The brand "ZedBoard" appears clearly in pictures. According to the company's website, the ZedBoard has everything the beginning developer needs to get started working in Android, Linux, and Windows. It does not appear to come with any of the advanced qubits that make up a quantum computer, and suggested uses include "video processing, reconfigurable computing, motor control, software acceleration," among others.

"I'm sure this board can work perfectly for people with more advanced [Field Programmable Gate Arrays] experience, however, I am a beginner and I can say that this is also a good beginner-friendly board," said one review on Diligent's website. Those interested in the board can buy one on Amazon for $589. It's impossible to know if Iran has figured out how to use off-the-shelf dev boards to make quantum algorithms, but it's not likely.

US To Allow South Korean, Taiwan Chip Makers To Keep Operations In China (msn.com) 27

According to the Wall Street Journal, the Biden administration is expected to allow leading semiconductor manufacturers from South Korea and Taiwan to continue and expand their chipmaking operations in China. From a report: Alan Estevez, undersecretary of commerce for industry and security, announced the decision at an industry gathering last week. The exemptions, initially granted for one year in October last year, were provided to several companies, including South Korea's Samsung Electronics and Taiwan Semiconductor Manufacturing, who have invested billions in building plants in China.

The decision to extend the exemptions reflects the challenges faced by U.S. authorities in isolating China from high-tech goods in a highly integrated global industry. The U.S. has been trying to keep advanced chips out of Chinese hands by limiting exports not only from American manufacturers but also those made by allies. However, U.S. and foreign chip makers have resisted these efforts, and governments in Asia and Europe have also pushed back. The most vocal criticism has come from South Korea, whose largest export market is China.

Western Digital Sparks Panic, Anger For Age-Shaming HDDs (arstechnica.com) 124

An anonymous reader quotes a report from Ars Technica: When should you be concerned about a NAS hard drive failing? Multiple factors are at play, so many might turn to various SMART (self-monitoring, analysis, and reporting technology) data. When it comes to how long the drive has been active, there are backup companies like Backblaze using hard drives that are nearly 8 years old. That may be why some customers have been panicked, confused, and/or angered to see their Western Digital NAS hard drive automatically given a warning label in Synology's DiskStation Manager (DSM) after they were powered on for three years. With no other factors considered for these automatic flags, Western Digital is accused of age-shaming drives to push people to buy new HDDs prematurely. The practice's revelation is the last straw for some users. Western Digital already had a steep climb to win back NAS customers' trust after shipping NAS drives with SMR (shingled magnetic recording) instead of CMR (conventional magnetic recording). Now, some are saying they won't use or recommend the company's hard drives anymore.

As users have reported online, including on Synology-focused and Synology's own forums, as well as on Reddit and YouTube, Western Digital drives using Western Device Digital Analytics (WDDA) are getting a "warning" stamp in Synology DSM once their power-on hours count hits the three-year mark. WDDA is similar to SMART monitoring and rival offerings, like Seagate's IronWolf, and is supposed to provide analytics and actionable items. The recommended action says: "The drive has accumulated a large number of power on hours [throughout] the entire life of the drive. Please consider to replace the drive soon." There seem to be no discernible problems with the hard drives otherwise.

Synology confirmed this to Ars Technica and noted that the labels come from Western Digital, not Synology. A spokesperson said the "WDDA monitoring and testing subsystem is developed by Western Digital, including the warning after they reach a certain number of power-on-hours." The practice has caused some, like YouTuber SpaceRex, to stop recommending Western Digital drives for the foreseeable future. In May, the YouTuber and tech consultant described his outrage, saying three years is "absolutely nothing" for a NAS drive and lamenting the flags having nothing to do with anything besides whether or not a drive has been in use for three years. A user on SynoForum discussed their "panic" upon seeing the label. And SpaceRex said one of its clients also panicked and quickly replaced the "warning" drives out of fear of losing business-critical data. "It is clearly predatory tactics by Western Digital trying to sell more hard drives," SpaceRex said in a June 10 video.
"Users are also concerned that this could prevent people from noticing serious problems with their drive," adds Ars. "Further, you can't repair a pool with a drive marked with a warning label."

Some of the affected products with WDDA include the WD Red Pro, WD Red Plus, and WD Purple. A discussion post about how to disable WDDA via SSH can be found here.

Will Submerging Computers Make Data Centers More Climate Friendly? (oregonlive.com) 138

20 miles west of Portland, engineers at an Intel lab are dunking expensive racks of servers "in a clear bath" made of motor oil-like petrochemicals, reports the Oregonian, where the servers "give off a greenish glow as they silently labor away on ordinary computing tasks." Intel's submerged computers operate just as they would on a dry server rack because they're not bathing in water, even though it looks just like it. They're soaking in a synthetic oil that doesn't conduct electricity. So the computers don't short out.

They thrive, in fact, because the fluid absorbs the heat from the hardworking computers much better than air does. It's the same reason a hot pan cools off a lot more quickly if you soak it in water than if you leave it on the stove.

As data centers grow increasingly powerful, the computers are generating so much heat that cooling them uses exorbitant amounts of energy. The cooling systems can use as much electricity as the computers themselves. So Intel and other big tech companies are designing liquid cooling systems that could use far less electricity, hoping to lower data centers' energy costs by as much as a third — and reducing the facilities' climate impact. It's a wholesale change in thinking for data centers, which already account for 2% of all the electricity consumption in the U.S... Skeptics caution that it may be difficult or prohibitively expensive to overhaul existing data centers to adapt to liquid cooling. Advocates of the shift, including Intel, say a transition is imperative to accommodate data centers' growing thirst for power. "It's really starting to come to a head as we're hitting the energy crisis and the need for climate action globally," said Jen Huffstetler, Intel's chief product sustainability officer...

Cooler computers can be packed more tightly together in data centers, since they don't need space for airflow. Computer manufacturers can pack chips together more tightly on the motherboard, enabling more computing power in the same space. And liquid cooling could significantly reduce data centers' environmental and economic costs. Conventional data centers' evaporative cooling systems require tremendous volumes of water and huge amounts of electricity...

Many other tech companies are backing immersion cooling, too. Google, Facebook and Microsoft are all helping fund immersion cooling research at Oregon State... [T]he timing may finally be right for data centers operators to make the shift away from air cooling to something far more efficient. Intel's Huffstetler said she expects to see liquid cooling become widespread in the next three to five years.

The article notes other challenges:
  • liquid adds more weight than some buildings' upper floors can support
  • Some metals degrade faster in liquid than they do in air.
  • And the engineers had to modify the servers by removing their fans — "because they serve no purpose while immersed."
