German Police Raid DDoS-Friendly Host 'FlyHosting' (krebsonsecurity.com) 5

An anonymous reader quotes a report from KrebsOnSecurity: Authorities in Germany this week seized Internet servers that powered FlyHosting, a dark web offering that catered to cybercriminals operating DDoS-for-hire services, KrebsOnSecurity has learned. FlyHosting first advertised on cybercrime forums in November 2022, saying it was a Germany-based hosting firm that was open for business to anyone looking for a reliable place to host malware, botnet controllers, or DDoS-for-hire infrastructure. A statement released today by the German Federal Criminal Police Office says they served eight search warrants on March 30, and identified five individuals aged 16-24 suspected of operating "an internet service" since mid-2021. The German authorities did not name the suspects or the Internet service in question.

"Previously unknown perpetrators used the Internet service provided by the suspects in particular for so-called 'DDoS attacks', i.e. the simultaneous sending of a large number of data packets via the Internet for the purpose of disrupting other data processing systems," the statement reads. The German authorities said that as a result of the DDoS attacks facilitated by the defendants, the websites of various companies as well as those of the Hesse police have been overloaded in several cases since mid-2021, "so that they could only be operated to a limited extent or no longer at times." The statement says police seized mobile phones, laptops, tablets, storage media and handwritten notes from the unnamed defendants, and confiscated servers operated by the suspects in Germany, Finland and the Netherlands.

Magnon-Based Computation Could Signal Computing Paradigm Shift (phys.org) 19

An anonymous reader quotes a report from Phys.Org: Like electronics or photonics, magnonics is an engineering subfield that aims to advance information technologies when it comes to speed, device architecture, and energy consumption. A magnon corresponds to the specific amount of energy required to change the magnetization of a material via a collective excitation called a spin wave. Because they interact with magnetic fields, magnons can be used to encode and transport data without electron flows, which involve energy loss through heating (known as Joule heating) of the conductor used. As Dirk Grundler, head of the Lab of Nanoscale Magnetic Materials and Magnonics (LMGN) in the School of Engineering explains, energy losses are an increasingly serious barrier to electronics as data speeds and storage demands soar. "With the advent of AI, the use of computing technology has increased so much that energy consumption threatens its development," Grundler says. "A major issue is traditional computing architecture, which separates processors and memory. The signal conversions involved in moving data between different components slow down computation and waste energy."

This inefficiency, known as the memory wall or Von Neumann bottleneck, has had researchers searching for new computing architectures that can better support the demands of big data. And now, Grundler believes his lab might have stumbled on such a "holy grail". While doing other experiments on a commercial wafer of the ferrimagnetic insulator yttrium iron garnet (YIG) with nanomagnetic strips on its surface, LMGN Ph.D. student Korbinian Baumgaertl was inspired to develop precisely engineered YIG-nanomagnet devices. With the Center of MicroNanoTechnology's support, Baumgaertl was able to excite spin waves in the YIG at specific gigahertz frequencies using radiofrequency signals, and -- crucially -- to reverse the magnetization of the surface nanomagnets. "The two possible orientations of these nanomagnets represent magnetic states 0 and 1, which allows digital information to be encoded and stored," Grundler explains.

The scientists made their discovery using a conventional vector network analyzer, which sent a spin wave through the YIG-nanomagnet device. Nanomagnet reversal happened only when the spin wave hit a certain amplitude, and could then be used to write and read data. "We can now show that the same waves we use for data processing can be used to switch the magnetic nanostructures so that we also have nonvolatile magnetic storage within the very same system," Grundler explains, adding that "nonvolatile" refers to the stable storage of data over long time periods without additional energy consumption. It's this ability to process and store data in the same place that gives the technique its potential to change the current computing architecture paradigm by putting an end to the energy-inefficient separation of processors and memory storage, and achieving what is known as in-memory computation.
The research has been published in the journal Nature Communications.

Google Drive Has a Hidden File Limit (9to5google.com) 40

Google Drive is enforcing a new file limit for the total number of files you can store on an account. 9to5Google reports: Some Google Drive users have recently noticed a message on their accounts which says that the account has reached its "creation limit" and won't accept any new files until existing ones are deleted. The issue was first highlighted by Ars Technica, and appears to be enforced for both free accounts as well as those subscribed to Google Workspace and Google One.

The issue was flagged by users on Reddit as well as Google's Issue Tracker and appears to have been put in place around mid-February. The file limit in place puts a hard ceiling on the total number of files stored in Google Drive at five million items. This limit ignores file size and type, and is a simple count of the number of files in your online storage bucket. This also includes items stored in the trash (which is automatically emptied every 30 days). When that limit is reached (or if the account has already exceeded it), Google Drive shows the following message: "This account has exceeded the creation limit of 5 million items. To create more items, move items to the trash and delete them forever."

One user reports having seven million items in their account prior to the limit being enforced, with their account no longer able to add any new files. Effectively, that user and anyone else in the same situation are locked out of their accounts, with the files stored now in a "read-only" mode. Google appears to have confirmed the limit to some users via support, but has yet to speak out publicly about it.

UK Government Gambles on Carbon Capture and Storage Tech Despite Scientists' Doubts (theguardian.com) 58

The UK government will defy scientific doubts to place a massive bet on technology to capture and store carbon dioxide in undersea caverns, to enable an expansion of oil and gas in the North Sea. From a report: Grant Shapps, the energy and net zero secretary, on Thursday unveiled the "powering up Britain" strategy, with carbon capture and storage (CCS) at its heart, during a visit to a nuclear fusion development facility in Oxford. Shapps said the continued production of oil and gas in the North Sea was still necessary, and that the UK had a geological advantage in being able to store most of the carbon likely to be produced in Europe for the next 250 years in the large caverns underneath the North Sea. "Unless you can explain how we can transition [to net zero] without oil and gas, we need oil and gas," he said. "I am very keen that we fill those cavities with storing carbon. I think there are huge opportunities for us to do that."

Shapps pointed to the $24.7bn the government is planning to spend over 20 years on developing CCS, which he said would generate new jobs and make the UK a world leader in the technology. Among the 1,000 pages of proposals to be published on Thursday will be boosts for offshore wind, hydrogen, heat pumps and electric vehicles. A green finance strategy, to be set out by the chancellor of the exchequer, Jeremy Hunt, will be aimed at mobilising private-sector money for investments in green industry, and there will be a consultation on carbon border taxes, aimed at penalising the import of high-carbon goods from overseas. But the plans contain no new government spending, and campaigners said they missed out key elements, such as a comprehensive programme of home insulation and a full lifting of the ban on new onshore wind turbines in England.

Norway Company Can't Produce Ukraine Ammunition Because of TikTok (theguardian.com) 258

quonset writes: In what has to be one of the most inconceivable confluences ever, the Norwegian company Nammo says it is unable to expand its production of artillery shells to support Ukraine because of "cat videos" on TikTok. To placate European scrutiny, TikTok is opening two data centers in Europe to house European user data locally. One of those data centers is in the Hamar region of Norway. Because of this expansion, there is no excess capacity for the factory to ramp up production of artillery shells.

"The chief executive of Nammo, which is co-owned by the Norwegian government, said a planned expansion of its largest factory in central Norway hit a roadblock due to a lack of surplus energy, with the construction of TikTok's new data centre using up electricity in the local area," reports the Guardian. "Elvia, the local energy provider, confirmed to the Financial Times that the electricity network had no spare capacity after allocating it to the data center on a first-come, first-served basis. Additional capacity would take time to become available."
"We are concerned because we see our future growth is challenged by the storage of cat videos," Morten Brandtzaeg told the Financial Times.

FTC Is Reviewing Competition in AI (bloomberg.com) 13

The US Federal Trade Commission is paying close attention to developments in artificial intelligence to ensure the field isn't dominated by the major tech platforms, Chair Lina Khan said Monday. From a report: "As you have machine learning that depends on huge amounts of data and also a huge amount of storage, we need to be very vigilant to make sure that this is not just another site for big companies to become bigger," Khan said at an event hosted by the Justice Department in Washington. Khan said companies offering AI tools need to make sure they are not "overselling or overstating" what their products can do. "Sometimes we see claims that are not fully vetted or not really reflecting how these technologies work," Khan said, noting recent guidance from the agency on AI-enabled products. "Developers of these tools can potentially be liable if technologies they are creating are effectively designed to deceive."

Arduino Announces 'UNO R4' with Clock Speed/Memory/Storage Upgrades, 32-bit ARM Cortex-M4 (arduino.cc) 70

Saturday Arduino announced "a new, revolutionary revision of the iconic UNO board," promising "a long-awaited update on performance and possibilities." The Arduino UNO R4 indeed preserves the well-known features of the UNO family — standard form factor, shield compatibility, 5V operating voltage, outstanding robustness — while offering no less than a 32-bit Cortex-M4 and a 3-to-16x increase in clock speed, memory and flash storage....

The UNO R4 will come in two versions — UNO R4 WiFi and UNO R4 Minima — offering unprecedented performance and possibilities for the maker community. The WiFi version comes with an Espressif S3 WiFi module, expanding creative opportunities for makers, educators, and hobbyists alike; while the UNO R4 Minima provides a cost-effective option for those seeking the new microcontroller without additional features....

SRAM went from 2kB to 32kB, and flash memory went from 32kB to 256kB to accommodate more complex projects. In addition, following the requests from the community, the USB port was upgraded to the USB-C and maximum power supply voltage was increased to 24V with an improved thermal design. The board provides a CAN bus, which allows users to minimize wiring and execute different tasks in parallel by connecting multiple shields. Finally, the new board includes a 12-bit analog DAC.

All in all, Arduino UNO R4 is the answer to the requests for improvement and updates the developer and maker community has been advancing, making it easier than ever to get started with Arduino.... On the software side, a big effort is being made to maximize retrocompatibility of the most popular Arduino libraries so that users will be able to rely on existing code examples and tutorials.

Google Defends Auto-Deletion of Chats After US Alleged It Destroyed Evidence (arstechnica.com) 81

Google defended its use of "history-off chats" for many internal communications, denying the US government's allegation that it intentionally destroyed evidence needed in an antitrust case. The history-off setting causes messages to be automatically deleted within 24 hours. Ars Technica reports: The US government and 21 states last month asked a court to sanction Google for allegedly using the auto-delete function on chats to destroy evidence and accused Google of falsely telling the government that it suspended its auto-deletion practices on chats subject to a legal hold. Google opposed the motion for sanctions on Friday in a filing (PDF) in US District Court for the District of Columbia. Google said it uses a "tiered approach" for preserving chats. "When there is litigation, Google instructs employees on legal hold not to use messaging apps like Google Chat to discuss the subjects at issue in the litigation and, if they must, to switch their settings to 'history on' for chats regarding the subjects at issue in the litigation, so that any such messages are preserved," the Google filing said.

Google said the government plaintiffs "contend that the Federal Rules specifically mandate that Google should have applied a forced history on setting for all custodians for all chats created while the custodian was on legal hold, regardless of the possible relevance of the message to the litigation." But federal rules only require "reasonable steps to preserve" information, Google pointed out. "Google's vast preservation efforts here -- and specifically its methodology with respect to history-off chats -- were 'reasonable steps' under the Rule," Google argued. Google said the US and state attorneys general "have not been denied access to material information needed to prosecute these cases and they have offered no evidence that Google intentionally destroyed such evidence." Google also argued that the objections came too late, alleging that the government knew before litigation began "that there was a subset of chats not automatically retained." "Plaintiffs' motions are barred at the outset because they were on notice of Google's approach to chats for years, yet did not object until well after the close of discovery. Those tactics should not be countenanced," Google told the court.

Google said its November 2019 disclosures in an ESI (Electronically Stored Information) questionnaire "show that the distinction between 'on-the-record' and other chats was apparent to anyone who wanted to pursue the matter from the outset of DOJ's investigation. For instance, the ESI Questionnaire response specifies that chat 'messages are generally retained for a period of 30 days if they have been marked on-the-record, and potentially longer if on-the-record messages are on legal hold.'" Google also said, "it is no secret how Google's Chat product operates" because it's a publicly available product and the Google Chat website explains the history-off feature. The Justice Department's motion last month said things happened very differently. "Google systematically destroyed an entire category of written communications every 24 hours" for nearly four years, the government motion said, continuing [...].

Nvidia DGX Cloud: Train Your Own ChatGPT in a Web Browser For $37K a Month 22

An anonymous reader writes: Last week, we learned that Microsoft spent hundreds of millions of dollars to buy tens of thousands of Nvidia A100 graphics chips so that partner OpenAI could train the large language models (LLMs) behind Bing's AI chatbot and ChatGPT.

Don't have access to all that capital or space for all that hardware for your own LLM project? Nvidia's DGX Cloud is an attempt to sell remote web access to the very same thing. Announced today at the company's 2023 GPU Technology Conference, the service rents virtual versions of its DGX Server boxes, each containing eight Nvidia H100 or A100 GPUs and 640GB of memory. The service includes interconnects that scale up to the neighborhood of 32,000 GPUs, storage, software, and "direct access to Nvidia AI experts who optimize your code," starting at $36,999 a month for the A100 tier.

Meanwhile, a physical DGX Server box can cost upwards of $200,000 for the same hardware if you're buying it outright, and that doesn't count the efforts companies like Microsoft say they made to build working data centers around the technology.

HDD Average Life Span Misses 3-Year Mark In Study of 2,007 Defective Drives (arstechnica.com) 64

An anonymous reader quotes a report from Ars Technica: An analysis of 2,007 damaged or defective hard disk drives (HDDs) has led a data recovery firm to conclude that "in general, old drives seem more durable and resilient than new drives." The statement comes from a Los Angeles-headquartered HDD, SSD, and RAID data recovery firm aptly named Secure Data Recovery that has been in business since 2007 and claims to have resolved more than 100,000 cases. It studied the HDDs it received in 2022. "Most" of those drives were 40GB to 10TB, according to a blog post by Secure Data Recovery spotted by Blocks & Files on Thursday.

Secure Data Recovery's March 8 post broke down the HDDs it received by engineer-verified "power-on hours," or the total amount of time the drive was functional, starting from when its owner began using it and ending when the device arrived at Secure Data Recovery. The firm also determined the drives' current pending sector count, depicting "the number of damaged or unusable sectors the hard drive developed during routine read-and-write operations." The company's data doesn't include HDDs that endured non-predictable failures or damage by unexpected events, such as electrical surges, malware, natural disasters, and "accidental mishandling," the company said.

Among the sample, 936 drives are from Western Digital, 559 come from Seagate, 211 are Hitachi brand, 151 are Toshiba's, 123 are Samsung's, and there are 27 Maxtor drives. Notably, 74.5 percent of the HDDs came from either Western Digital or Seagate, which Secure Data Recovery noted accounted for 80 percent of hard drive shipments in 2021, citing Digital Storage Technology Newsletter data shared by Forbes. The average time before failure among the sample size was 2 years and 10 months, and the 2,007 defective HDDs had an average of 1,548 bad sectors. "While 1,548 bad sectors out of hundreds of millions or even billions of disk subdivisions might seem minuscule, the rate of development often increases, and the risk of data corruption multiplies," the blog said.
"We found that the five most durable and resilient hard drives from each manufacturer were made before 2015," says Secure Data Recovery. "On the other hand, most of the least durable and resilient hard drives from each manufacturer were made after 2015." One of the reasons for this may have to do with HDD manufacturers "pushing the performance envelope," adds Ars. "This includes size limits that cut 'allowance between moving parts, appearing to affect mechanical damage and wear resistance.'"

Secure Data Recovery also believes that shingled magnetic recording (SMR) impacts HDD reliability, as the disks place components under "more stress."

"What this study shows is not the average working life of a hard disk drive," notes Blacks & Files. "Instead it provides the average working life if a failed disk drive. Cloud storage provider Backblaze issues statistics about the working life of its disk drive fleet and its numbers are quite different." A recent report of theirs found that SSDs are more reliable than HDDs.

Zippyshare Quits After 17 Years, 45 Million Visits Per Month Makes No Money (torrentfreak.com) 81

After almost 17 years online, file-hosting veteran Zippyshare will shut down at the end of the month. TorrentFreak: Founded in 2006, Zippyshare was known for its free, no-nonsense, no-frills approach to storing files online. Having changed very little over the years, Zippyshare's operators say the platform is now a dinosaur that costs too much to run in a world where ad-blocking is widespread. Zippyshare said, "Since 2006 we have been on the market in an unchanged form, that is, as ad financed/free file hosting. However, you have been visiting in less and less over the years, as the arguably very simple formula of the services we offer is slowly running out of steam. I guess all the competing file storage service companies on the market look better, offer better performance and more features. No one needs a dinosaur like us anymore."

System76 Meerkat Mini-Linux PC - Now with Up to Intel Core i7-1260P (liliputing.com) 26

Liliputing.com has an update about the System76 Meerkat, which they describe as "a compact desktop computer with support for up to 64GB of RAM, up to two storage devices (for as much as 16TB of total storage), and up to an Intel Core i7 mobile processor. It's basically a rebranded Intel NUC." (Escept that System76 offers a choice of Pop!_OS or Ubuntu Linux pre-installed.)

"Previously available with a choice of 10th or 11th-gen Intel Core processor options, the Meerkat now also supports 12th-gen Intel chips." That means there are a total of 9 different processor options available. Prices start at $499 for an entry-level model with a Core i3-10110U processor, 8GB of RAM and a 128GB SSD. The prices rises by $50 if you want to go with a Core i3-1135G4 model, while prices start at $599 for a Meerkat mini PC with a 12th-gen Intel Core processor....

But the biggest difference is that Intel's 12th-gen processors introduce a hybrid architecture that pairs Performance and Efficiency cores, leading to much higher core counts for better multi-core performance.

All-Open Source 7-Inch MNT Reform Pocket Laptop Ships In October (arstechnica.com) 36

An anonymous reader quotes a report from Ars Technica: The creators of the all-open source MNT Reform laptop are getting nearer to launching its handheld counterpart: The crowdfunding campaign for the 7-inch MNT Pocket Reform has officially launched and is also serving as a de-facto preorder system for the device. The cheapest version of the Pocket Reform starts at $899, and it's also being offered in purple for $969 or in a bundle with a 1TB SSD, carrying case, handbook, and poster for $1,299. All versions are currently slated to ship in mid-October.

Like the full-size Reform, the pocket version uses open source hardware and a mechanical keyboard (buyers can choose either white or red Kalih switches). But the pocket version uses a 7-inch 1920x1200 LCD screen instead of a 12.5-inch version and comes with fewer and smaller ports (two USB-C, one micro HDMI, a microSD port, and one ix industrial mini Ethernet port). Its keyboard also comes with an individually programmable RGB backlight, and its trackball-style pointing device has been downsized to fit into the smaller design. The Pocket Reform also includes built-in Wi-Fi and Bluetooth, 128GB of built-in eMMC storage, and an expansion slot for 4G cellular connectivity. The device will also boot from microSD cards or an NVMe SSD installed in the device's M.2 slot. Its 8000 mAh batteries will allow it to run for about four hours.
MNT warns in its blog post that "risks and challenges" could delay the October shipping timeline:

"Pocket Reform has hundreds of electronic components. We tried to pick them so that there will be enough stock when we get around to manufacturing the boards, but it's always possible that there could be a sudden component shortage or increase in price. If that should happen, we would have to re-engineer the affected PCB and exchange the part, causing a delay in continued production. We had to adapt our products several times during the global chip crisis, so we are confident that we'll be able to work around any difficulties. Should any situation arise that would delay the estimated shipping timeline, backers will be informed promptly via project updates."

Google Is Rolling Out More AI Features for Customers on the Cloud (bloomberg.com) 6

Google announced a raft of new artificial intelligence-powered features for customers of its cloud-computing business, as the technology giant jostles for dominance in the burgeoning field with rivals such as Microsoft and startup OpenAI. From a report: As Silicon Valley buzzes about so-called generative AI -- software that can create images, text and video based on user prompts -- Google Cloud offered a glimpse of what it's doing to keep up in the race. In a demonstration, the company showed how cloud customers will be able to use its AI tools to create presentations and sales-training documents, take notes during meetings and draft emails to colleagues. The company also made some of its underlying AI models available to developers so they can build their own applications using Google's technology.

Alphabet-owned Google also said Tuesday it had signed up a flurry of AI startups as customers for its cloud service, including Midjourney, which offers an image-generation system, and AI21, which specializes in technology known as large language models. Google is offering young AI-focused businesses $250,000 in free use of its cloud -- which provides computing horsepower and storage -- for the first year, which the company said is 2 1/2 times what it typically offers. "We believe in having a broad, vibrant partner ecosystem for AI," Thomas Kurian, chief executive officer of Google Cloud, said in an interview.

US Plans More Regulations to Improve Cloud Security (politico.com) 12

Politico reports: Governments and businesses have spent two decades rushing to the cloud — trusting some of their most sensitive data to tech giants that promised near-limitless storage, powerful software and the knowhow to keep it safe.

Now the White House worries that the cloud is becoming a huge security vulnerability.

So it's embarking on the nation's first comprehensive plan to regulate the security practices of cloud providers like Amazon, Microsoft, Google and Oracle, whose servers provide data storage and computing power for customers ranging from mom-and-pop businesses to the Pentagon and CIA.... Among other steps, the Biden administration recently said it will require cloud providers to verify the identity of their users to prevent foreign hackers from renting space on U.S. cloud servers (implementing an idea first introduced in a Trump administration executive order). And last week the administration warned in its national cybersecurity strategy that more cloud regulations are coming — saying it plans to identify and close regulatory gaps over the industry....

So far, cloud providers have haven't done enough to prevent criminal and nation-state hackers from abusing their services to stage attacks within the U.S., officials argued, pointing in particular to the 2020 SolarWinds espionage campaign, in which Russian spooks avoided detection in part by renting servers from Amazon and GoDaddy. For months, they used those to slip unnoticed into at least nine federal agencies and 100 companies. That risk is only growing, said Rob Knake, the deputy national cyber director for strategy and budget. Foreign hackers have become more adept at "spinning up and rapidly spinning down" new servers, he said — in effect, moving so quickly from one rented service to the next that new leads dry up for U.S. law enforcement faster than it can trace them down.

On top of that, U.S. officials express significant frustration that cloud providers often up-charge customers to add security protections — both taking advantage of the need for such measures and leaving a security hole when companies decide not to spend the extra money. That practice complicated the federal investigations into the SolarWinds attack, because the agencies that fell victim to the Russian hacking campaign had not paid extra for Microsoft's enhanced data-logging features.... Part of what makes that difficult is that neither the government nor companies using cloud providers fully know what security protections cloud providers have in place. In a study last month on the U.S. financial sector's use of cloud services, the Treasury Department found that cloud companies provided "insufficient transparency to support due diligence and monitoring" and U.S. banks could not "fully understand the risks associated with cloud services."

Scientists Propose Turning Carbon Pollution Into Baking Soda and Storing it In Oceans (cnn.com) 107

Slashdot reader beforewisdom shared this report from CNN: Scientists have set out a way to suck planet-heating carbon pollution from the air, turn it into sodium bicarbonate and store it in oceans, according to a new paper. The technique could be up to three times more efficient than current carbon capture technology, say the authors of the study, published Wednesday in the journal Science Advances....

The team have used copper to modify the absorbent material used in direct air capture. The result is an absorbent "which can remove CO2 from the atmosphere at ultra-dilute concentration at a capacity which is two to three times greater than existing absorbents," Arup SenGupta, a professor at Lehigh University and a study author, told CNN. This material can be produced easily and cheaply and would help drive down the costs of direct air capture, he added. Once the carbon dioxide is captured, it can then be turned into sodium bicarbonate — baking soda — using seawater and released into the ocean at a small concentration.

The oceans "are infinite sinks," SenGupta said. "If you put all the CO2 from the atmosphere, emitted every day — or every year — into the ocean, the increase in concentration would be very, very minor," he said. SenGupta's idea is that direct air capture plants can be located offshore, giving them access to abundant amounts of seawater for the process.

Stuart Haszeldine, professor of carbon capture and storage at the University of Edinburgh, who was not involved in the study, told CNN that the chemistry was "novel and elegant." The process is a modification of one we already know, he said, "which is easier to understand, scale-up and develop than something totally new."

Backblaze Finds SSDs Are More Reliable Than HDDs 51

williamyf writes: The fine folks at Backblaze have published their first ever report that includes their SSD fleet. To the surprise of no one, SSDs are more more reliable (0.98% AFR) than HDDs (1.64% AFR). The surprising thing thing was how small the difference is (0.66% AFR).

A TL;DR article by well regarded storage reporter Chris Mellor is here. Also worthy of note: S.M.A.R.T. attribute usage among SSD makers is neither standardized, nor very smart:

"Klein notes that the SMART (Self-Monitoring, Analysis, and Reporting Technology) used for drive state reporting is applied inconsistently by manufacturers. "Terms like wear leveling, endurance, lifetime used, life used, LBAs [Logical Block Address] written, LBAs read, and so on are used inconsistently between manufacturers, often using different SMART attributes, and sometimes they are not recorded at all."

That means you can't use such SMART statistics to make valid comparisons between the drives. "Come on, manufacturers. Standardize your SMART numbers."

Denmark Inaugurates World's First Cross-Border CO2 Storage Site (euractiv.com) 29

New submitter sonlas writes: Denmark is inaugurating Project Greensand, the first cross-border CO2 storage site, shipping CO2 from Belgium to store it into a depleted oil field under the Danish North Sea. "With the first injection taking place on Wednesday, the project aims to safely and permanently store up to eight million tons of CO2 every year by 2030, the equivalent of 40% of Denmark's emission reduction target and over 10% of the country's annual emissions," reports Euractiv. However, this is to be put in perspective with global CO2 emissions, which reached a new high of more than 36.8 billions tons in 2022.

A report by Rystad Energy shows that if investments were to quadruple, we should be able to capture 150 million of tons of CO2 per year by 2025, still a drop of water in, or under, the ocean. Furthermore, the whole process of sequestering CO2 underground emits itself ~21% of the amount of CO2 stored, as shown in a study by Australian think tank IEEFA.
