  • US Cyber Agency Is Using Anthropic's Mythos To Audit Government Code
    by BeauHD on 07/07/2026 at 11:00 am

    CISA is reportedly using Anthropic's Mythos model to scan government code repositories for security vulnerabilities, with sources saying the audits have already found numerous bugs. Reuters reports: The scanning is being done by CISA's Attack Surface Evaluation team, according to one of the sources. The team is a group within CISA that conducts digital security assessments and hacking exercises across government. Two of the sources said the audits had already uncovered a large number of vulnerabilities but did not elaborate. Reuters could not establish exactly how much government code the team had gone through or the nature or severity of the bugs it discovered. [...] The National Security Agency, the U.S. government's powerful eavesdropping agency, has been using Mythos as far back as April despite the blacklist, Axios has reported. Late last month, the New York Times said that NSA analysts had been testing Mythos in classified settings and coming away impressed with its capabilities. But when Anthropic rolled out a public version of Mythos called Fable, which included what it described as cybersecurity safeguards, the White House suddenly demanded that it ban foreigners from running it. This triggered a global shutdown of the model that was lifted only last week. Read more of this story at Slashdot.

  • GitHub Thumbs Nose At Sony's Controversial End to Physical Media With Its Introduction of Repo CDs
    by BeauHD on 07/07/2026 at 7:00 am

    GitHub is offering a limited run of 1,000 CD-ROM copies of public repositories as a pro-physical-media jab at Sony's plan to stop producing PlayStation game discs in 2028. Tom's Hardware reports: The coding and collaboration platform, owned by Microsoft, states that "In light of recent developments in physical media, GitHub is proud to announce that you can now obtain your public repo on CD-ROM." Moreover, it appeals to the human side of computing, adding the emotive line "Keep it. Lend it to friends. Pass it on to your children." It isn't April 1st, so thankfully this is no joke. However, if you check out the above-linked GitHub Your Code, On a CD offer page, it quickly becomes clear this is a very limited in time/scope stunt. "Order a burned CD of your own public GitHub repo. Yes, a real physical disc you can hold in your hands, no download required," begins the spiel. But this is a very limited run of 1,000 discs, with applications required between July 2 and July 6 (inclusive). Limit one per person, with availability varying between country/region. "Your code is physically yours, forever. Until you lose it, let's be real," says GitHub. At best, these CDs will be framed and put on a wall, some becoming collector's items or eBay money spinners (discs like 0001 or 0888 would be good ones, if they are numbered). Also, many will be lost or eventually/accidentally discarded, as GitHub seems to know. So this 'protest' is arguably 1,000 doses of expensively shipped e-waste. Read more of this story at Slashdot.

  • Research Universities Are Admitting Fewer PhDs, a Bad Sign For Science
    by BeauHD on 07/07/2026 at 3:30 am

    An anonymous reader quotes a report from the New York Times: The number of students admitted to Ph.D. programs this fall dropped 15 percent from the previous year, according to data from over 50 top research universities, raising fears that the nation's capacity to produce new science could be diminished. The decline is driven, in part, by a chaotic and unpredictable federal funding environment under the Trump administration, as federal cuts are promised and then reversed, and budgets remain unclear. A reduction in doctoral students could mean fewer scholars at universities to teach and mentor undergraduates. Higher education leaders also worry that, if the declines continue, there will be fewer researchers to power a rapidly evolving scientific work force. The data showing the decrease comes from 55 universities, all of them members of the Association of American Universities, an invitation-only organization that includes 69 of the most prestigious research institutions in the United States. The data collection was conducted by another group, the Association of American Universities Data Exchange. Schools in A.A.U. confer half of the nation's research doctorates, according to the association. "We are at risk of losing a whole generation of new talent because of the reduction in the capacity to support those students," said Toby Smith, a senior vice president at the A.A.U. University leaders and research advocates cite many reasons for the declines in new doctoral students. Key federal agencies, such as the National Institutes of Health and the National Science Foundation, have been funding fewer research grants. The wealthiest institutions also face a new federal tax on their endowments. But the most cited reason in interviews was the unreliable nature of federal funding under the Trump administration. The administration proposed major cuts to federal research agencies last year, but Congress restored the funding. It is again proposing big cuts. While Congress may again reverse the administration's proposed reductions, the uncertainty makes it hard for schools to make multiyear commitments to doctoral students. The administration also abruptly ended thousands of research grants last year, arguing that they did not align with the government's priorities. The administration restored many of the grants after judges deemed the eliminations illegal and arbitrary, but research advocates say the whiplash was damaging. Read more of this story at Slashdot.

  • Small AI Models Gain Traction Around the World
    by BeauHD on 06/07/2026 at 11:00 pm

    locater16 shares a report from IEEE Spectrum: One morning in 2019, Adebayo Alonge was in a Cape Town hotel room, preparing to demonstrate his startup's AI answer to a serious problem in African health care: counterfeit medication, which kills thousands of people across the continent every year. The RxScanner is a handheld spectrometer that scans a pill with infrared light, then sends the item's molecular profile to an AI model equipped with a pharmaceutical database. In seconds, the AI identifies the medication from its molecular profile -- or reports that it's phony. Pharmacies were using the system in more than a dozen countries, including Ghana, Kenya, Myanmar, and Alonge's native Nigeria. But that morning in South Africa, it didn't work. "I was shocked," Alonge says... So Alonge immediately asked his engineers to shrink the AI model down to a smaller, low-power, unconnected version that could run entirely on his Android phone. They produced it 2 hours later, and that saved the demo. More importantly, the work birthed a new version of his device, which can authenticate a pill in places without broadband, computers, or even reliable electricity. It also turned Alonge into an advocate for this kind of "small AI." "The article goes on to detail other immediately useful 'small' AI applications without any subscription or billion dollar data centers needed," writes locator16. For example, Bala Murugan and colleagues at Vellore Institute of Technology in India developed a drone-based system that photographs cashew plants and identifies disease-indicating splotches on the plants. The key advantage is that all processing happens on the drone itself, so farmers do not need a computer, broadband connection, or cloud server access. In a Uruguayan vineyard, researchers developed small-AI systems to identify ant infestations. The article doesn't go deep into the deployment details, but it presents this as another example of a narrow, localized model trained to recognize a specific agricultural threat. Small AI has also been used to detect the presence of malaria-carrying mosquitoes in multiple countries. This is especially useful in regions where public-health teams may lack reliable network access or expensive lab infrastructure, but still need fast, local detection. In parts of Brazil without access to more complex medical equipment, researchers have used small AI to run electrocardiograms from an Arduino device. The article also describes Marcelo Jose Rovai's work on a TinyML model that generates electrocardiograms in a patient simulator lab. Rovai also describes a newer experiment using an Arduino UNO Q with a Qualcomm chipset. The device runs a language model locally, collects sensor data, and analyzes it to detect tiny pools of water where mosquitoes might breed -- while using only about 3 watts of power.

  • Supreme Court Allows Texas To Require Age Verification For Mobile Apps
    by BeauHD on 06/07/2026 at 10:00 pm

    The Supreme Court allowed Texas to enforce a law requiring app stores to verify users' ages and obtain parental consent before minors can download apps. Tech industry groups argue the law broadly restricts young people's access to digital speech, but the court let a 5th Circuit order stand without explanation or noted dissents. CNN notes that the Supreme Court's decision "doesn't resolve the case but rather will allow Texas to enforce the law while the litigation continues to play out." From the report: "A minor child who downloads a software application from an app store agrees to contractual terms of service, including whether the child's location will be tracked, whether the child's privacy will be protected, whether information from the child's phone can be sold by the developer, and whether the child waives the right to sue," Texas told the Supreme Court in urging the court to allow its law to take effect. But the Computer & Communications Industry Association, a trade group whose members include Apple and Google, said the law would effectively bar young people from accessing a wide range of content, "be it a book by Ernest Hemingway or J.K. Rowling, a Taylor Swift album, or a subscription to National Geographic." Allowing the law to take effect, the group said, would have "profound consequences for the protection of digital speech." [...] In the new case, involving Texas' age verification for apps, a federal district court blocked the law's enforcement in December -- days before it was set to take effect. But a three-judge panel of the conservative 5th US Circuit Court of Appeals put that decision on hold in early June, allowing the state to enforce it. By declining to take up the emergency appeal from the computer and student groups, the Supreme Court has left the 5th Circuit's decision in place. Read more of this story at Slashdot.

  • South Korea's SK Hynix Launching $28 Billion US Listing To Ride Global AI Wave
    by BeauHD on 06/07/2026 at 9:00 pm

    SK Hynix is launching a Nasdaq listing expected to raise about $28 billion, giving US investors easier access to one of the biggest beneficiaries of the AI memory-chip boom. Reuters reports: The company will sell 17.79 million new shares in the depository receipt listing on the Nasdaq. Ten ADRs will represent one common share and the stock will be sold in a price range that is due to be revealed on Monday, based on SK Hynix's Seoul trading price. SK Hynix's share price was down 4% at 2,327,000 won each on Monday, but the stock is up about 273% this year, as it rides surging global investor demand for AI stocks. Korea's KOSPI was down 2.2% on Monday. [...] SK Hynix has been among the world's largest beneficiaries of the AI boom as it outperformed its major rivals Samsung and Micron. "This is more than a liquidity event," said Dave Mazza, the chief executive officer of Roundhill Investments in New York, which manages an exchange-traded fund tracking DRAM manufacturers, which is one of the most popular ways for U.S. investors to trade SK Hynix's stock. "SK Hynix has been one of the most important companies in the world that most U.S. institutions could not easily own." "The listing removes an accessibility discount, not a quality discount." [...] SK Hynix said the proceeds from the listing of the American Depositary Receipts will be used to build chip factories in South Korea and buy chipmaking equipment including an extreme ultraviolet scanner made by Dutch equipment maker ASML. The final price of the New York listing is due to be set on Thursday, ahead of the stock starting trade on Friday, regulatory filings showed. The company's management will meet global investors on a roadshow this week. The deal is expected to be the second-biggest share sale after a record $85.7 billion initial public offering by SpaceX last month, surpassing Saudi Aramco's $25.6 billion IPO in 2019 and Alibaba's similar-sized offering in 2014.
