DOJ Makes Its First Known Arrest For AI-Generated CSAM (engadget.com) 98

In what's believed to be the first case of its kind, the U.S. Department of Justice arrested a Wisconsin man last week for generating and distributing AI-generated child sexual abuse material (CSAM). Even if no children were used to create the material, the DOJ "looks to establish a judicial precedent that exploitative materials are still illegal," reports Engadget. From the report: The DOJ says 42-year-old software engineer Steven Anderegg of Holmen, WI, used a fork of the open-source AI image generator Stable Diffusion to make the images, which he then used to try to lure an underage boy into sexual situations. The latter will likely play a central role in the eventual trial for the four counts of "producing, distributing, and possessing obscene visual depictions of minors engaged in sexually explicit conduct and transferring obscene material to a minor under the age of 16." The government says Anderegg's images showed "nude or partially clothed minors lasciviously displaying or touching their genitals or engaging in sexual intercourse with men." The DOJ claims he used specific prompts, including negative prompts (extra guidance for the AI model, telling it what not to produce) to spur the generator into making the CSAM.

Cloud-based image generators like Midjourney and DALL-E 3 have safeguards against this type of activity, but Ars Technica reports that Anderegg allegedly used Stable Diffusion 1.5, a variant with fewer boundaries. Stability AI told the publication that fork was produced by Runway ML. According to the DOJ, Anderegg communicated online with the 15-year-old boy, describing how he used the AI model to create the images. The agency says the accused sent the teen direct messages on Instagram, including several AI images of "minors lasciviously displaying their genitals." To its credit, Instagram reported the images to the National Center for Missing and Exploited Children (NCMEC), which alerted law enforcement. Anderegg could face five to 70 years in prison if convicted on all four counts. He's currently in federal custody before a hearing scheduled for May 22.

Windows Now Has AI-Powered Copy and Paste 59

Umar Shakir reports via The Verge: Microsoft is adding a new Advanced Paste feature to PowerToys for Windows 11 that can convert your clipboard content on the fly with the power of AI. The new feature can help people speed up their workflows by doing things like copying code in one language and pasting it in another, although its best tricks require OpenAI API credits.

Advanced Paste is included in PowerToys version 0.81 and, once enabled, can be activated with a special key command: Windows Key + Shift + V. That opens an Advanced Paste text window that offers paste conversion options including plaintext, markdown, and JSON. If you enable Paste with AI in the Advanced Paste settings, you'll also see an OpenAI prompt where you can enter the conversion you want -- summarized text, translations, generated code, a rewrite from casual to professional style, Yoda syntax, or whatever you can think to ask for.

Microsoft Is Making File Explorer More Powerful With Version Control and 7z Compression (theverge.com) 44

Sean Hollister reports via The Verge: At Build, Microsoft now says it's adding native version control to File Explorer by integrating systems like Git, letting you see new changes and comments directly from the app. Here's a cropped and zoomed version of the provided screenshot so you can get a better look. [...] Microsoft says it's also letting File Explorer natively compress files to 7-zip and TAR; currently, the right-click context menu has a "Compress to ZIP file" option, but ZIP is thought to be a bit antiquated in terms of how much compression you get.

Gordon Bell, an Architect of Our Digital Age, Dies At Age 89 (arstechnica.com) 6

An anonymous reader quotes a report from Ars Technica: Computer pioneer Gordon Bell, who as an early employee of Digital Equipment Corporation (DEC) played a key role in the development of several influential minicomputer systems and also co-founded the first major computer museum, passed away on Friday, according to Bell Labs veteran John Mashey. Mashey announced Bell's passing in a social media post on Tuesday morning. "I am very sad to report [the] death May 17 at age 89 of Gordon Bell, famous computer pioneer, a founder of Computer Museum in Boston, and a force behind the @ComputerHistory here in Silicon Valley, and good friend since the 1980s," wrote Mashey in his announcement. "He succumbed to aspiration pneumonia in Coronado, CA."

Bell was a pivotal figure in the history of computing and a notable champion of tech history, having founded Boston's Computer Museum in 1979, which later became the heart of the Computer History Museum in Mountain View, with his wife Gwen Bell. He was also the namesake of the ACM's prestigious Gordon Bell Prize, created to spur innovations in parallel processing.
Bell also mentored at Microsoft in 1995, where he "studied telepresence technologies and served as the subject of the MyLifeBits life-logging project," reports Ars. "The initiative aimed to realize Vannevar Bush's vision of a system that could store all the documents, photos, and audio a person experienced in their lifetime."

Former Windows VP Steven Sinofsky said Bell "was immeasurably helpful at Microsoft where he was a founding advisor and later full time leader in Microsoft Research. He advised and supported countless researchers, projects, and product teams. He was always supportive and insightful beyond words. He never hesitated to provide insights and a few sparks at so many of the offsites that were so important to the evolution of Microsoft."

"His memory is a blessing to so many," added Sinofsky in a post memorializing Bell. "His impact on all of us in technology will be felt for generations. May he rest in peace."

Match Group, Meta, Coinbase And More Form Anti-Scam Coalition (engadget.com) 23

An anonymous reader shares a report: Scams are all over the internet, and AI is making matters worse (no, Taylor Swift didn't giveaway Le Creuset pans, and Tom Hanks didn't promote a dental plan). Now, companies such as Match Group, Meta and Coinbase are launching Tech Against Scams, a new coalition focused on collaboration to prevent online fraud and financial schemes. They will "collaborate on ways to take action against the tools used by scammers, educate and protect consumers and disrupt rapidly evolving financial scams."

Meta, Coinbase and Match Group -- which owns Hinge and Tinder -- first joined forces on this issue last summer but are now teaming up with additional digital, social media and crypto companies, along with the Global Anti-Scam Organization. A major focus of this coalition is pig butchering scams, a type of fraud in which a scammer tricks someone into giving them more and more money through trusting digital relationships, both romantic and platonic in nature.

Google Cuts Mystery Check To US In Bid To Sidestep Jury Trial (reuters.com) 38

An anonymous reader quotes a report from Reuters: Alphabet's Google has preemptively paid damages to the U.S. government, an unusual move aimed at avoiding a jury trial in the Justice Department's antitrust lawsuit over its digital advertising business. Google disclosed (PDF) the payment, but not the amount, in a court filing last week that said the case should be heard and decided by a judge directly. Without a monetary damages claim, Google argued, the government has no right to a jury trial. The Justice Department, which has not said if it will accept the payment, declined to comment on the filing. Google asserted that its check, which it said covered its alleged overcharges for online ads, allows it to sidestep a jury trial whether or not the government takes it.

The Justice Department filed the case last year with Virginia and other states, alleging Google was stifling competition for advertising technology. The government has said Google should be forced to sell its ad manager suite. Google, which has denied the allegations, said in a statement that the Justice Department "manufactured a damages claim at the last minute in an attempt to secure a jury trial." Without disclosing the size of its payment, Google said that after months of discovery, the Justice Department could only point to estimated damages of less than $1 million. The company said the government has said the case is "highly technical" and "outside the everyday knowledge of most prospective jurors."

Neuralink To Test Brain Implant On Second Patient (axios.com) 47

The FDA has approved Neuralink to implant its brain chip in a second patient. According to the Wall Street Journal, the company also outlined fixes to an electrode problem that caused its chip to detach from the first patient's brain. They were unharmed and could still control a computer mouse using their thoughts. Axios reports: Neuralink, which is owned by Elon Musk, said it is seeking applications for another patient with quadriplegia to test if the device can allow a person to do tasks like control a phone and computer. It outlined fixes that included embedding some of the device's wiring deeper into the brain, the Wall Street Journal reported, citing a document and a person familiar with the company.

Neuralink rival Synchron is preparing a large-scale clinical trial with an eye toward seeking commercial approval of its implant. Mass General Brigham has also launched a collaborative effort with stakeholders and the FDA to accelerate the development of the implanted devices.

HP Resurrects '90s OmniBook Branding, Kills Spectre and Dragonfly (arstechnica.com) 53

HP announced today that it will resurrect the "Omni" branding it first coined for its business-oriented laptops introduced in 1993. The vintage branding will now be used for the company's new consumer-facing laptops, with HP retiring the Spectre and Dragonfly brands in the process. Furthermore, computers under consumer PC series names like Pavilion will also no longer be released. "Instead, every consumer computer from HP will be called either an OmniBook for laptops, an OmniDesk for desktops, or an OmniStudio for AIOs," reports Ars Technica. From the report: The computers will also have a modifier, ranging from 3 up to 5, 7, X, or Ultra to denote computers that are entry-level all the way up to advanced. For instance, an HP OmniBook Ultra would represent HP's highest-grade consumer laptop. "For example, an HP OmniBook 3 will appeal to customers who prioritize entertainment and personal use, while the OmniBook X will be designed for those with higher creative and technical demands," Stacy Wolff, SVP of design and sustainability at HP, said via a press announcement today. [...] So far, HP has announced one new Omni computer, the OmniBook X. It has a 12-core Snapdragon X Elite X1E-78-100, 16GB or 32GB of MPDDR5x-8448 memory, up to 2TB of storage, and a 14-inch, 2240x1400 IPS display. HP is pointing to the Latin translation of omni, meaning "all" (or everything), as the rationale behind the naming update. The new name should give shoppers confidence that the computers will provide all the things that they need.

HP is also getting rid of some of its commercial series names, like Pro. From now on, new, lower-end commercial laptops will be ProBooks. There will also be ProDesktop desktops and ProStudio AIOs. These computers will have either a 2 modifier for entry-level designs or a 4 modifier for ones with a little more power. For example, an HP ProDesk 2 is less powerful than an HP ProDesk 4. Anything more powerful will be considered either an EliteBook (laptops), EliteDesk (desktops), or EliteStudio (AIOs). For the Elite computers, the modifiers go from 6 to 8, X, and then Ultra. A Dragonfly laptop today would fall into the Ultra category. HP did less overhauling of its commercial lineup because it "recognized a need to preserve the brand equity and familiarity with our current sub-brands," Wolff said, adding that HP "acknowledged the creation of additional product names like Dragonfly made those products stand out, rather than be seen as part of a holistic portfolio." [...]

As you might now expect of any tech rebranding, marketing push, or product release these days, HP is also announcing a new emblem that will appear on its computers, as well as other products or services, that substantially incorporate AI. The two laptops announced today carry the logo. According to Wolff, on computers, the logo means that the systems have an integrated NPU "at 40+ trillions of operations per second." They also come with a chatbot based on ChatGPT 4, an HP spokesperson told me.

Return-To-Office Mandate Is Backfiring On a Key Federal Agency (thehill.com) 101

An anonymous reader quotes a report from The Hill: In the wake of the COVID-19 pandemic, the dynamics of the workplace have undergone a seismic shift. While some heralded the return to the office as a sign of normalcy, evidence suggests that for many, this transition has been far from smooth sailing. Nowhere is this struggle more evident than in the case of the U.S. federal government employees, particularly those within the Department of Justice. At the beginning of the year, the Justice Department initiated a return-to-office policy requiring much of its workforce to be present in person for up to six days per pay period or about three days per week. However, there were more stringent requirements for assistant U.S. attorneys. While approximately 70 percent of AUSAs currently enjoy the flexibility of two days per week of telework, recent changes in telework policies within certain offices have left many feeling stranded.

A survey by the National Association of Assistant U.S. Attorneys (NAAUSA) reveals a stark contrast in job satisfaction between those with telework options and those without. In offices where routine telework has been curtailed, a staggering 81 percent of respondents admitted they were actively seeking alternative employment opportunities. This dissatisfaction stands in contrast to offices where some level of telework is maintained, where only 42 percent of respondents expressed a desire to leave their current positions. NAAUSA Vice President Adam Hanna aptly summarizes the situation as a "workforce revolt." It's a sentiment echoed by employees across various offices, underscoring the critical importance of telework in retaining talent and maintaining morale. This is yet another testament to the value placed on flexibility and work-life balance -- crucial factors in the recruitment and retention of top talent. In response to the survey findings, NAAUSA has urged Justice Department leadership to implement consistent telework policies across all offices. The organization recommends a minimum baseline of two telework days per week, citing the importance of treating employees as responsible professionals capable of balancing in-person and remote work effectively.

The issue extends beyond individual preferences, resonating with broader concerns surrounding recruitment, retention, and workplace culture. Employee organizations within the Justice Department have united in calling for a review of return-to-office mandates, citing potential negative impacts on productivity and workforce retention. These findings align with broader evidence of telework's positive effects, including the Office of Personnel Management's annual report (PDF) about telework in the federal government. That report showed that a staggering 68 percent of teleworking federal government employees intend to remain in their current positions, in contrast to a mere 53 percent of non-telecommuters. This underscores the pivotal role of telework in fostering employee loyalty and commitment.

Microsoft Paint Is Getting an AI-Powered Image Generator (engadget.com) 41

Microsoft Paint is getting a new image generator tool called Cocreator that can generate images based on text prompts and doodles. Engadget reports: During a demo at its Surface event, the company showed off how Cocreator combines your own drawings with text prompts to create an image. There's also a "creativity slider" that allows you to control how much you want AI to take over compared with your original art. As Microsoft pointed out, the combination of text prompts and your own brush strokes enables faster edits. It could also help provide a more precise rendering than what you'd be able to achieve with DALL-E or another text-to-image generator alone.

'Prism' Translation Layer Does For Arm PCs What Rosetta Did For Macs (arstechnica.com) 37

An anonymous reader quotes a report from Ars Technica: Microsoft is going all-in on Arm-powered Windows PCs today with the introduction of a Snapdragon X Elite-powered Surface Pro convertible and Surface Laptop, and there are inevitable comparisons to draw with another big company that recently shifted from Intel's processors to Arm-based designs: Apple. A huge part of the Apple Silicon transition's success was Rosetta 2, a translation layer that makes it relatively seamless to run most Intel Mac apps on an Apple Silicon Mac with no extra effort required from the user or the app's developer. Windows 11 has similar translation capabilities, and with the Windows 11 24H2 update, that app translation technology is getting a name: Prism.

Microsoft says that Prism isn't just a new name for the same old translation technology. Translated apps should run between 10 and 20 percent faster on the same Arm hardware after installing the Windows 11 24H2 update, offering some trickle-down benefits that users of the handful of Arm-based Windows 11 PCs should notice even if they don't shell out for new hardware. The company says that Prism's performance should be similar to Rosetta's, though obviously this depends on the speed of the hardware you're running it on. Microsoft also claims that Prism will further improve the translation layer's compatibility with x86 apps, though the company didn't get into detail about the exact changes it had made on this front.

Google Thinks the Public Sector Can Do Better Than Microsoft's 'Security Failures' (theverge.com) 27

An anonymous reader shares a report: Google is pouncing on Microsoft's weathered enterprise security reputation by pitching its services to government institutions. Pointing to a recent report from the US Cyber Safety Review Board (CSRB) that found that Microsoft's security woes are the result of the company "deprioritizing" enterprise security, Google says it can help. The company's pitch isn't quite as direct as Microsoft CEO Satya Nadella saying he made Google dance, but it's spicy all the same. Repeatedly referring to Microsoft as "the vendor" throughout its blog post on Monday, Google says the CSRB "showed that lack of a strong commitment to security creates preventable errors and serious breaches." Platforms, it added, "have a responsibility" to hold to strong security practices. And of course, who is more responsible than Google?

OpenAI Says Sky Voice in ChatGPT Will Be Paused After Concerns It Sounds Too Much Like Scarlett Johansson (tomsguide.com) 54

OpenAI is pausing the use of the popular Sky voice in ChatGPT over concerns it sounds too much like the "Her" actress Scarlett Johansson. From a report: The company says the voices in ChatGPT were from paid voice actors. A final five were selected from an initial pool of 400 and it's purely a coincidence the unnamed actress behind the Sky voice has a similar tone to Johansson. Voice is about to become more prominent for OpenAI as it begins to roll out a new GPT-4o model into ChatGPT. With it will come an entirely new conversational interface where users can talk in real-time to a natural-sounding and emotion-mimicking AI.

While the Sky voice and a version of ChatGPT Voice have been around for some time, the comparison to Johansson became more obvious due to OpenAI CEO Sam Altman, and many others, drawing the similarity between the new AI model and the movie "Her". In "Her," Scarlett Johansson voices an advanced AI operating system named Samantha, who develops a romantic relationship with a lonely writer played by Joaquin Phoenix. With its ability to mimic emotional responses, the parallels from GPT-4o were obvious.

38% of Webpages That Existed in 2013 Are No Longer Accessible a Decade Later 62

A new Pew Research Center analysis shows just how fleeting online content actually is: 1. A quarter of all webpages that existed at one point between 2013 and 2023 are no longer accessible, as of October 2023. In most cases, this is because an individual page was deleted or removed on an otherwise functional website.
2. For older content, this trend is even starker. Some 38% of webpages that existed in 2013 are not available today, compared with 8% of pages that existed in 2023.

This "digital decay" occurs in many different online spaces. We examined the links that appear on government and news websites, as well as in the "References" section of Wikipedia pages as of spring 2023. This analysis found that:
1. 23% of news webpages contain at least one broken link, as do 21% of webpages from government sites. News sites with a high level of site traffic and those with less are about equally likely to contain broken links. Local-level government webpages (those belonging to city governments) are especially likely to have broken links.
2. 54% of Wikipedia pages contain at least one link in their "References" section that points to a page that no longer exists.[...]

Some People Who Rented a Tesla from Hertz Were Still Charged for Gas (thedrive.com) 195

"Last week, we reported on a customer who was charged $277 for gasoline his rented Tesla couldn't have possibly used," writes the automotive blog The Drive.

"And now, we've heard from other Hertz customers who say they've been charged even more." Hertz caught attention last week for how it handled a customer whom it had charged a "Skip the Pump" fee, which allows renters to pay a premium for Hertz to refill the tank for them. But of course, this customer's rented Tesla Model 3 didn't use gas — it draws power from a battery — and Hertz has a separate, flat fee for EV recharges. Nevertheless, the customer was charged $277.39 despite returning the car with the exact same charge they left with, and Hertz refused to refund it until after our story ran. It's no isolated incident either, as other customers have written in to inform us that it happened to them, too....

Evan Froehlich returned the rental at 21 percent charge, expecting to pay a flat $25 recharge fee. (It's ordinarily $35, but Hertz's loyalty program discounts it.) To Froehlich's surprise, he was hit with a $340.97 "Skip the Pump" fee, which can be applied after returning a car if it's not requested beforehand. He says Hertz's customer service was difficult to reach, and that it took making a ruckus on social media to get Hertz's attention. In the end, a Hertz representative was able to review the charge and have it reversed....

A March 2023 Facebook post documenting a similar case indicates this has been happening for more than a year.

After renting a Tesla Model 3, another customer even got a $475.19 "fuel charge," according to the article — in addition to a $25 charging fee: They also faced a $125.01 "rebill" for using the Supercharger network during their rental, which other Hertz customers have expressed surprise and frustration with. Charging costs can vary, but a 75-percent charge from a Supercharger will often cost in the region of just $15.

Ubuntu 24.10 to Default to Wayland for NVIDIA Users (omgubuntu.co.uk) 76

An anonymous reader shared this report from the blog OMG Ubuntu: Ubuntu first switched to using Wayland as its default display server in 2017 before reverting the following year. It tried again in 2021 and has stuck with it since. But while Wayland is what most of us now log into after installing Ubuntu, anyone doing so on a PC or laptop with an NVIDIA graphics card present instead logs into an Xorg/X11 session.

This is because NVIDIA's proprietary graphics drivers (which many, especially gamers, opt for to get the best performance, access to full hardware capabilities, etc) have not supported Wayland as well as as they could've. Past tense as, thankfully, things have changed in the past few years. NVIDIA's warmed up to Wayland (partly as it has no choice given that Wayland is now standard and a 'maybe one day' solution, and partly because it wants to: opportunities/benefits/security).

With the NVIDIA + Wayland sitch' now in a better state than before — but not perfect — Canonical's engineers say they feel confident enough in the experience to make the Ubuntu Wayland session default for NVIDIA graphics card users in Ubuntu 24.10.

Linux Foundation Announces Launch of 'High Performance Software Foundation' (linuxfoundation.org) 4

This week the nonprofit Linux Foundation announced the launch of the High Performance Software Foundation, which "aims to build, promote, and advance a portable core software stack for high performance computing" (or HPC) by "increasing adoption, lowering barriers to contribution, and supporting development efforts."

It promises initiatives focused on "continuously built, turnkey software stacks," as well as other initiatives including architecture support and performance regression testing. Its first open source technical projects are:

- Spack: the HPC package manager.

- Kokkos: a performance-portable programming model for writing modern C++ applications in a hardware-agnostic way.

- Viskores (formerly VTK-m): a toolkit of scientific visualization algorithms for accelerator architectures.

- HPCToolkit: performance measurement and analysis tools for computers ranging from desktop systems to GPU-accelerated supercomputers.

- Apptainer: Formerly known as Singularity, Apptainer is a Linux Foundation project providing a high performance, full featured HPC and computing optimized container subsystem.

- E4S: a curated, hardened distribution of scientific software packages.

As use of HPC becomes ubiquitous in scientific computing and digital engineering, and AI use cases multiply, more and more data centers deploy GPUs and other compute accelerators. The High Performance Software Foundation will provide a neutral space for pivotal projects in the high performance computing ecosystem, enabling industry, academia, and government entities to collaborate on the scientific software.

The High Performance Software Foundation benefits from strong support across the HPC landscape, including Premier Members Amazon Web Services (AWS), Hewlett Packard Enterprise, Lawrence Livermore National Laboratory, and Sandia National Laboratories; General Members AMD, Argonne National Laboratory, Intel, Kitware, Los Alamos National Laboratory, NVIDIA, and Oak Ridge National Laboratory; and Associate Members University of Maryland, University of Oregon, and Centre for Development of Advanced Computing.

In a statement, an AMD vice president said that by joining "we are using our collective hardware and software expertise to help develop a portable, open-source software stack for high-performance computing across industry, academia, and government." And an AWS executive said the high-performance computing community "has a long history of innovation being driven by open source projects. AWS is thrilled to join the High Performance Software Foundation to build on this work. In particular, AWS has been deeply involved in contributing upstream to Spack, and we're looking forward to working with the HPSF to sustain and accelerate the growth of key HPC projects so everyone can benefit."

The new foundation will "set up a technical advisory committee to manage working groups tackling a variety of HPC topics," according to the announcement, following a governance model based on the Cloud Native Computing Foundation.

China Uses Giant Rail Gun to Shoot a Smart Bomb Nine Miles Into the Sky (futurism.com) 134

"China's navy has apparently tested out a hypersonic rail gun," reports Futurism, describing it as "basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds."

But "during a demonstration of its power, things didn't go quite as planned." As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful. This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have. This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt."
But what's more interesting is the project itself. "Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space.... which for the record did not make it all the way to space..." Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too.
Japan and France also have railgun projects, according to a recent article from Defense One. "Yet the nation that has demonstrated the most continuing interest is China," with records of railgun work dating back as far as 2011: The Chinese team claimed that their railgun can fire a projectile 100 to 200 kilometers at Mach 6. Perhaps most importantly, it uses up to 100,000 AI-enabled sensors to identify and fix any problems before critical failure, and can slowly improve itself over time. This, they said, had enabled them to test-fire 120 rounds in a row without failure, which, if true, suggests that they solved a longstanding problem that reportedly bedeviled U.S. researchers. However, the team still has a ways to go before mounting an operational railgun on a ship; according to one Chinese article, the projectiles fired were only 25mm caliber, well below the size of even lightweight naval artillery.

As with many other Chinese defense technology programs, much remains opaque about the program...

While railguns tend to get the headlines, this lab has made advances in a wide range of electric and electromagnetic applications for the PLA Navy's warships. For example, the lab's research on electromagnetic launch technology has also been applied to the development of electromagnetic catapults for the PLAN's growing aircraft carrier fleet...

While it remains to be seen whether the Chinese navy can develop a full-scale railgun, produce it at scale, and integrate it onto its warships, it is obvious that it has made steady advances in recent years on a technology of immense military significance that the US has abandoned.
