A proposed California bill would require 3D printer makers to use state-certified software to detect and block files for gun parts, but advocates at the Electronic Frontier Foundation (EFF) say it would be easy to evade and could lead to widespread surveillance of users' printing activity. The Register reports: The bill in question is AB 2047, the scope of which, on paper, appears strict. The primary goal is clear and simple: to require 3D printer manufacturers to use a state-certified algorithm that checks digital design files for firearm components and blocks print jobs that would produce prohibited parts. [...] Cliff Braun and Rory Mir, who respectively work in policy and tech community engagement at the EFF, claim that the proposals in California are technically infeasible and in practice will lead to consumer surveillance. In a series of blog posts published this month, the pair argued that print-blocking technology -- proposals for which have also surfaced in states including New York and Washington - cannot work for a range of technical reasons. They argued that because 3D printers and other types of computer numerical control (CNC) machines are fairly simple, with much of their brains coming from the computer-aided manufacturing (CAM) software -- or slicer software -- to which they are linked, the bill would establish legal and illegal software. Proprietary software will likely become the de facto option, leaving open source alternatives to rot. "Under these proposed laws, manufacturers of consumer 3D printers must ensure their printers only work with their software, and implement firearm detection algorithms on either the printer itself or in a slicer software," wrote Braun earlier this month. "These algorithms must detect firearm files using a maintained database of existing models. Vendors of printers must then verify that printers are on the allow-list maintained by the state before they can offer them for sale. Owners of printers will be guilty of a crime if they circumvent these intrusive scanning procedures or load alternative software, which they might do because their printer manufacturer ends support." Braun also argued that it would be trivial for anyone who uses 3D printers to make small tweaks to either the visual models of firearms parts, or the machine instructions (G-code) generated from those models, to evade detection. Mir further argued that the bill offers no guardrails to keep this "constantly expanding blacklist" limited to firearm-related designs. In his view, there is a clear risk that this approach will creep into other forms of alleged unlawful activity, such as copyright infringement. [...] Braun and Mir have a list of other arguments against the bill. They say the algorithms are more than likely to lead to false positives, which will prevent good-faith users from using their hardware. Many 3D printer owners also have no interest in printing firearm components. Most simply want the freedom to print trinkets and spare parts while others use them to print various items and sell them as an income stream.

alternative_right shares a report from 404 Media: An independent privacy audit of Microsoft, Meta, and Google web traffic in California found that the companies may be violating state regulations and racking up billions in fines. According to the audit from privacy search engine webXray, 55 percent of the sites it checked set ad cookies in a user's browser even if they opted out of tracking. Each company disputed or took issue with the research, with Google saying it was based on a "fundamental misunderstanding" of how its product works. The webXray California Privacy Audit viewed web traffic on more than 7,000 popular websites in California in the month of March and found that most tech companies ignore when a user asks to opt-out of cookie tracking. California has stringent and well defined privacy legislation thanks to its California Consumer Privacy Act (CCPA) which allows users to, among other things, opt out of the sale of their personal information. There's a system called Global Privacy Control (GPC), which includes a browser extension that indicates to a website when a user wants to opt out of tracking. According to the webXray audit, Google failed to let users opt out 87 percent of the time. "Google's failure to honor the GPC opt-out signal is easy to find in network traffic. When a browser using GPC connects to Google's servers it encodes the opt-out signal by sending the code 'sec-gpc: 1.' This means Google should not return cookies," the audit said. "However, when Google's server responds to the network request with the opt-out it explicitly responds with a command to create an advertising cookie named IDE using the 'set-cookie' command. This non-compliance is easy to spot, hiding in plain sight." The audit said that Microsoft fails to opt out users in the same way and has a failure rate of 50 percent in the web traffic webXray viewed. Meta's failure rate was 69 percent and a bit more comprehensive. "Meta instructs publishers to install the following tracking code on their websites. The code contains no check for globally standard opt-out signals -- it loads unconditionally, fires a tracking event, and sets a cookie regardless of the consumer's privacy preferences," the audit said. It showed a copy of Meta's tracking data which contains no GPC check at all.

Google is rolling out a Chrome feature called "Skills" that lets users save Gemini prompts as reusable one-click workflows they can run across multiple tabs. The feature also includes preset Skills from Google. It's launching first for Chrome desktop users set to US English. The Verge reports: Once you have access to the feature, it can be managed by typing a forward slash ( / ) in Gemini and clicking the compass icon. AI prompts can be saved as Skills directly from your Gemini chat history on desktop, where they'll then be available to reuse on any other desktop devices that are signed into the same Google account on Chrome. The aim is to spare Chrome users from having to manually retype frequently used Gemini prompts or having to copy and paste them over from a saved list. Some of the Skills made by early testers include commands for calculating the nutritional information of online recipes and creating a side-by-side comparison of product specifications while shopping across multiple tabs, according to Google. The company is also launching a library of preset Skills that you can save and use instead of making your own. These ready-to-use Skills can also be customized to better suit your needs, providing a starting point without requiring you to create your own from scratch.

A Chicago concert superfan Aadam Jacobs who has recorded more than 10,000 shows since the 1980s is working with Internet Archive volunteers to digitize the collection before the cassettes deteriorate. "So far, about 2,500 of these tapes have been posted on the Internet Archive, including some rare gems like a Nirvana performance from 1989," reports TechCrunch. From the report: For many of these recordings, Jacobs was using pretty mediocre equipment, but the volunteer audio engineers working with the Internet Archive have made these tapes sound great. One volunteer, Brian Emerick, drives to Jacobs' house once a month to pick up more boxes of tapes -- he has to use anachronistic cassette decks to play the tapes, which get converted into digital files. From there, other volunteers clean up, organize, and label the recordings, even tracking down song names from forgotten punk bands. The archive is available here.

UK Prime Minister Keir Starmer said social media platforms should remove addictive infinite-scroll features for young users as Britain considers new child-safety measures. "We're consulting on whether there should be a ban for under 16s," Starmer told BBC Radio. "But I think equally important, the addictive scrolling mechanisms are really problematic to my mind. They need to go." Reuters reports: Britain, like other countries, is considering restricting access to social media for children and it is testing bans, curfews and app time limits to see how they impact sleep, family life and schoolwork. Social media companies had designed algorithms that were intended to encourage addictive behavior, and parents were asking the government to intervene, Starmer said. [...] More than 45,000 people had already responded to its consultation on children's online safety, the UK government said, adding that there was still time to contribute before a deadline of May 26. "We want to hear from mums and dads who are worried about the amount of time their children spend online and what they are viewing," Technology Secretary Liz Kendall said on Monday. "We want to hear from teenagers who know better than anyone what it is like to grow up in the age of social media. And we want to hear from families about their views on curfews, AI chatbots and addictive features."

An anonymous reader quotes a report from Bloomberg: Alphabet's Google is facing billions of dollars in potential damage claims as part of mass arbitration tied to the company's online search and advertising technology businesses, which courts have ruled were illegal monopolies. Advertisers are banding together to seek payouts through mass arbitration proceedings. While many companies that displayed ads purchased through Google -- including USA Today Co. and Advance Publications -- have sued for damages since the rulings in 2024, advertiser contracts with the search giant require mandatory arbitration over legal disputes. In arbitration, legal disputes are handled by a mediator, a process that tends to favor companies in individual claims. Mass arbitration -- where 25 or more claims against the same company are pooled together -- have become more common and provide a greater likelihood of settlement awards for claimants. Ashley Keller, a Chicago lawyer whose firm has handled mass arbitrations against DoorDash, Postmates and TurboTax-maker Intuit, said he's already signed up a "significant number" of advertisers to participate in claims against Google. The first of those are expected to be filed this week. "Two federal judges have already adjudicated Google to be a monopolist," Keller said in an interview with Bloomberg. "It seems sensible to seek redress." Keller, who is also representing Texas and other states in a lawsuit against Google for monopolization of advertising technology, estimates potential claims for online search and display ads could reach $218 billion or more, based on calculations from an economist his firm has hired. Similar mass arbitrations have lasted 12 to 24 months between the filing of claims and resolution, he said. "Given the nature of these matters, we cannot estimate a possible loss," Google said in a recent corporate filing. "We believe we have strong arguments against these open claims and will defend ourselves vigorously."

Researchers at the University of Southern California say they've developed a memristor memory device that continued operating at 700 degrees Celsius. "And crucially, 700 degrees was not the limit, it was simply as hot as their testing equipment could go," adds ScienceAlert. "The device showed no signs of failing." From the report: The device is called a memristor and it's a nanoscale component that can both store information and perform computing operations. Think of it as a tiny sandwich with two electrode layers on the outside and a thin ceramic filling in the middle. The team built theirs from tungsten, the metal with the highest melting point of any element, combined with a ceramic called hafnium oxide, and with a layer of graphene at the bottom. Each material can withstand enormous heat. Together, they turned out to be extraordinary. What makes graphene the key ingredient is the way it interacts with tungsten at the atomic level. In a conventional device, heat causes metal atoms to drift slowly through the ceramic layer until they bridge the two electrodes, short circuiting everything and leaving the device permanently broken. Graphene stops that process dead. Its surface chemistry with tungsten is ... almost like oil and water. Tungsten atoms that drift toward the graphene find they simply cannot take hold, no anchor, no short circuit, no failure. The team used advanced electron microscopy and quantum level computer simulations to understand exactly why, turning a single lucky result into a repeatable principle. The findings have been published in the journal Science.

J. Allen Hynek started as an Air Force consultant brought in to help explain away early UFO reports, but over time he grew frustrated with what he saw as the government's effort to minimize unexplained cases rather than seriously investigate them. Longtime Slashdot reader schwit1 shares an article from Popular Mechanics, in collaboration with Biography.com, that argues Hynek's shift from skeptic to advocate helped shape modern ufology, and that the Air Force's attempts to control the narrative may have deepened the public distrust and conspiracy thinking that followed. From the report: Do you think the U.S. government is hiding, and possibly reverse-engineering, extraterrestrial technology? Think again. Or better yet, don't think about it at all. Nothing to see here. That's the underlying message of a report released in 2024 by the Department of Defense. The 63-page "Report on the Historical Record of U.S. Government Involvement with Unidentified Anomalous Phenomena (UAP) " concludes that the DoD's All-Domain Anomaly Resolution Office (AARO) "found no evidence that any [U.S. Government] investigation, academic-sponsored research, or official review panel has confirmed that any sighting of a UAP represented extraterrestrial technology." The AARO, as The Guardian summarizes, is "a government office established in 2022 to detect and, as necessary, mitigate threats including 'anomalous, unidentified space, airborne, submerged and transmedium objects.'" This report came on the heels of, and in contradiction to, what was arguably the most high-profile hearing on UAPs -- formerly known as unidentified flying objects, or UFOs -- in decades: the August 2023 testimony of "whistleblower" Dave Grusch. [...] The 2024 AARO report stated that during the time Hynek was working with Project Blue Book [the U.S. Air Force's best-known UFO investigation program], "about 75 percent of Americans trusted the [US government] 'to do the right thing almost always or most of the time.'" But, the report noted, since 2007, that number has never risen above 30 percent. "This lack of trust probably has contributed to the belief held by some subset of the U.S. population that the USG has not been truthful regarding knowledge of extraterrestrial craft." Ultimately, the Air Force's efforts to stifle Hynek -- pressuring him to offer the public standard responses to questions he wasn't even allowed to ask -- appears to have backfired. Ironically, the Air Force's attempts to quiet suspicions only fueled them, leading to more conspiracy theories and distrust. People came to believe that the government was hiding the truth, contrary to Hynek's actual revelation: that, in reality, the people at the top may not care much about finding the answers after all.
