  • 'Steve Jobs In Exile' Remembers the Birth of the Web and 'Making Unix Taste Sweet'
    by EditorDavid on 07/06/2026 at 7:34 am

    Ars Technica shares some anecdotes from Steve Jobs in Exile, a new book released last month: [Author Geoffrey] Cain reminds us, in stunning detail, that Jobs' "exile" era at NeXT was not only critical to his evolution as a man and an entrepreneur, but that it mattered for the rest of us, too. The technological innovations that came out of NeXT — notably, the NeXTSTEP OS — continue to live on in what we now call both macOS and iOS. As Cain puts it, "NeXTSTEP was Steve's attempt to make Unix taste sweet...." [W]hile many tech nerds know that Tim Berners-Lee created the first World Wide Web server on a NeXT machine while working in Switzerland in 1990, few know that NeXT employees were wary of bringing the news to Jobs. Why? They feared his wrath "and that he would dismiss [the web] as 'shit.'" (In another timeline, NeXT might itself have capitalized on this world-changing innovation....) Perhaps one of the wildest anecdotes that Cain uncovered was how one voicemail changed computer history forever. In 1996, when Apple was solidly in its mediocre Performa era — and considering buying BeOS as the basis for its new operating system — a mid-level NeXT product manager asked aloud, "Why don't we just frickin' call Apple?" (NeXT was also struggling during this period.) And so someone did. As Cain writes: Garrett left the group of managers, walked back to his office, and took a risk. He picked up his designer phone and called the head of software at Apple. He left what he described as "one of my more inspired sales pitches" on the man's voicemail, explaining why Apple should be looking at NeXT instead of Be... In any other universe, Garrett's call might have gotten him fired. But in this timeline, it worked out. And thanks to him, Steve [Jobs] was about to enter Apple's airspace once again.

  • Scientists Edited Human Embryo Genes. But Questions Remain
    by EditorDavid on 07/06/2026 at 4:41 am

    "A DNA-editing feat involving editing the genes of early stage embryos was announced this week," reports the Wall Street Journal. They describe the feat as "a far cry from designer babies, but nevertheless a step in that direction." Dieter Egli, an associate professor of developmental cell biology at Columbia University and his co-authors, including Nathan Treff of Nucleus Genomics, a New York-based DNA-testing startup, say the technology could help fix disease-causing mutations in embryos. "We're not throwing the final 'OK, you will have gene-edited babies tomorrow' at the public," said Egli. "That is a process that can occur through discussion matched with scientific progress...." Previous gene-editing efforts have often used Crispr, which can cut out parts of the DNA sequence, but the technology can also cause damage if the wrong DNA is targeted or cut out. In 2018, Chinese scientist He Jianku said he used Crispr to tweak DNA in human embryos and was imprisoned for the work. The technology Egli's group used, called base editing, allows them to target individual DNA letters in sequences more precisely with fewer adverse effects... Egli's group focused on altering two genes, one that can raise the risk of heart disease and one that is tied to blood disorders like sickle cell disease, and the research showed they were sometimes able to do so successfully, in the same embryo, without damage. "I am generally supportive of the concept of embryo editing to prevent genetic disease," said Dr. Paula Amato, a fertility expert at Oregon Health & Science University who wasn't involved in the research... Base editing has been used in human embryos before, according to peer-reviewed studies. The technology was used to correct a disease-causing mutation and an Alzheimer's disease-risk gene variant, said Alexis Komor, associate professor of biochemistry and molecular biophysics at the University of California, San Diego, who wasn't involved in the work. "There really is not any unmet medical or clinical need for this, especially from an in vitro fertilization perspective," Komor said. "Usually what you'll hear is that they're doing it just so that you know we can prevent genetic diseases, but there are so many other better ways to do that." Using embryo editing to create babies is illegal in the U.S. and many other countries. Scientists have long worried that it is a slippery slope and that the technology could ultimately be used to promote eugenics. Her worry is that "they're basically building a blueprint" for more ethically problematic forms of embryo editing. "In my opinion, I think this is a huge no-no," Komor said. "There's just no ethical way to use this...." Nucleus Genomics Chief Executive Kian Sadeghi said his company plans to fund Egli's further research, building on the new findings. His company sells a polygenic embryo-screening product, which screens prospective parents' embryos and produces risk scores for their likelihood of developing disease, as well as factors like height, IQ and eye color. The company has said the IQ predictions are limited in accuracy. The research was published online Monday on a preprint server. Read more of this story at Slashdot.

  • Failing CS Grades Soar At UC Berkeley As Professors See Greater AI Usage
    by EditorDavid on 07/06/2026 at 2:41 am

    The University of California at Berkeley discovered the percentage of failing grades in multiple CS classes this spring "is significantly higher than past semesters," reports the campus's student newspaper. "Instructors point to students' increased reliance on AI, lack of mathematical preparedness and understaffing as potential contributing factors." According to [coursework platform] Berkeleytime, 35.3% of CS 10 students and 10.6% of CS 61A students received F's in spring 2026. In spring 2025 and spring 2024, the percentage of F's did not exceed 10% for either class. The electrical engineering and computer sciences department's grading guidelines state that 7% of students in lower division courses, including CS 10 and CS 61A, should receive D's and F's... [UC Berkeley teaching professor Dan Garcia, who taught both classes] believes the "primary driver" of these abnormally high failing rates is due to a "vast increase in academic dishonesty" due to students' usage of large language models, such as Claude, ChatGPT and Google Gemini. "Some of the numbers that you saw from the number of students who receive failing grades were because we caught them (cheating) and prosecuted them and are sending their cases to the Center for Student Conduct," Garcia said. "But in other cases, it's students who are leaning a little too hard on LLMs to do their work for them, and then at exam time just really aren't ready." According to Garcia, nearly 30 students in CS 10 were "caught cheating on take-home exams" in spring 2026... In addition to overreliance on AI, Garcia also pointed out that many students are underprepared mathematically, a concern echoed by campus associate teaching professor Gireeja Ranade. Ranade noticed a similar lack of prerequisite mathematical skills in her spring 2026 EECS 127 class, "Optimization Models in Engineering," which she described as "differently challenging" to teach this semester. The class saw a 16.8% F rate, far higher than the 5% of D's and F's that the EECS department describes as "typical" for an upper division course... Both Garcia and Ranade have joined more than 1,300 UC faculty in signing a petition calling for the reinstatement of ACT and SAT standardized testing scores for STEM admissions in the UC system.

  • Cheaper EV Sales are Increasing
    by EditorDavid on 07/06/2026 at 12:40 am

    Sales have increased for Hyundai's under-$35,000 IONIQ 5, totalling 18,395 for the first five months of 2026, reports Electrek, "up 16% from the same period last year." But meanwhile BYD's overseas sales surpassed 160,000 for the first time last month, "up 80% from May 2025 and 19% from the previous record of 135,098 set in April." Through the first five months of 2026, BYD sold 616,263 vehicles overseas. In May, overseas sales accounted for over 41% of BYD's total sales. In several major markets, including the UK, BYD surpassed Tesla and Kia to become the best-selling EV brand through April. "With fuel prices remaining high, more drivers are turning to electric vehicles as a smarter and more economical choice," Bono Ge, BYD UK's Country Manager, said last month. Elsewhere Electrek notes that Toyota's bZ (starting at under $35,000) was the third-best-selling EV in the U.S. in the first three months of 2026, behind only the Tesla Model 3 and Model Y. "Last month, bZ sales doubled from May 2025, with 2,646 units sold." And meanwhile the first Volkswagen ID. Polo and Cupra Raval models "rolled off the production line at the Group's Martorell plant in Spain, the first of several new affordable, mass-market EVs." Starting at €24,995 ($29,000) and €26,000 ($30,100), the ID. Polo and Cupra Raval are the first models from the Group's Electric Urban Car Family... [T]he first customer deliveries are scheduled to begin later this summer and into the fall. Following the ID. Polo and Cupra Raval, Volkswagen will introduce new members to the Electric Urban Car Family, including the ID. Cross, an electric version of the T-Cross, later this year. According to Volkswagen, the ID. Cross will start at around €28,000 ($32,500). Read more of this story at Slashdot.

  • EU's Tech Sovereignty Package Includes 29 Pages on Open Source, Says Open Source Initiative
    by EditorDavid on 06/06/2026 at 10:40 pm

    Friday the Open Source Initiative welcomed the EU's new tech sovereignty package, noting that "over a third of the 29-page document is devoted to Open Source." The nonprofit OSI — maintainers of the Open Source definition — submitted their official feedback in February, and notes that "many" of their key requests were addressed, "as well as some exciting new announcements!" One of the biggest barriers to Open Source adoption has been public procurement. Too often, tenders have been designed around proprietary solutions, ignoring the benefits of Open Source and locking public institutions into closed ecosystems. The OSI called for procurement rules that prioritize interoperability, reusability, and vendor independence. The package takes a major step forward in this area. The EU pledges to make the public sector an anchor consumer for Open Source solutions. The Commission plans to reform procurement rules to remove barriers for Open Source, provide better guidance to EU countries on procurement criteria to avoid excluding Open Source, and uphold the "public money, public code" principle when procuring software development. Both proposals align with the OSI's feedback. The next critical step is the EU's public procurement law reform. The OSI will continue advocating to ensure these pledges translate into action. Beyond procurement, the OSI highlighted challenges faced by Open Source communities in Europe, particularly difficulties accessing investment and expertise to commercialize and scale projects. The Commission has responded by committing to ensure Open Source companies are considered for funding under the European Competitiveness Fund (ECF). It also plans to create "Open Source business accelerators" that will offer mentorship, training, legal and licensing consulting, and business development support, including marketing. Additionally, the Commission will work to raise industry awareness of Open Source solutions by leveraging the EU's existing business support networks. These measures directly address the OSI's concerns and could significantly boost the Open Source ecosystem in Europe... [I]n our feedback, we called for the continuation of the Next Generation Internet (NGI) initiative that has funded many Open Source projects, and for the creation of a European Sovereign Tech Fund to fund ongoing maintenance and features development to meet the EU's needs. We also highlighted the need to mainstream Open Source in other funding opportunities (like the €100bn+ Horizon Europe programme). The Commission's strategy addresses these requests. The NGI will be scaled up under the new name "Open Internet Stack." A new Open Source Maintenance Instrument will fund the "maintenance and security upkeep of essential components." The Commission will also create a list of critical and security-relevant Open Source dependencies to inform funding decisions and promote Open Source solutions as the default approach in Horizon Europe funding. Friday's announcement from the Open Source Initiative notes that the EU is already leading by example in Open Source adoption. It applauds the EU for "deploying a Matrix-based communications system and the openDesk collaboration environment internally, trialing an alternative operating system to replace Windows, which is currently widely used in EU institutions, and expanding its presence on the Fediverse, with Commissioners and key departments already joining the EU's Mastodon server.'

  • Hospital Ordered to Pay $13M Over 2022 Death of Star Trek's Nichelle Nichols
    by EditorDavid on 06/06/2026 at 9:40 pm

    The Root reports: A New Mexico jury has found the Gila Regional Medical Center negligent in the death of Nichelle Nichols, who famously played Lieutenant Nyota Uhura on the hit television series "Star Trek." According to KRQE News 13, Nichols' family filed a lawsuit against the hospital last year following her 2022 admission for shortness of breath. Nichols' family claimed that she should have received a full cardiac examination, but the medical personnel sent her to the observation unit, and she was discharged the next day. After being transported to her assisted living home, the 89-year-old passed away just seven hours later. In response to Nichol's tragic passing, the lawsuit alleged that Gila Medical Center "hired, credentialed, and inappropriately supervised unqualified medical providers" who treated the actress. The lawsuit also alleged that the hospital failed to secure a bed for Nichols or transfer her to a facility that had one. Furthermore, the attorney argued that the staff should have known that the assisted living center was not equipped to handle a patient with her medical needs. On Thursday (June 4), a jury found the hospital negligent and awarded Nichols' estate $13 million. KRQE got this quote from the estate's attorney about the death of the 89-year-old acctress. "At the end of the day, Nichelle Nichols had a heart attack that was missed. Thatâ(TM)s why she died." The jury deliberated for "just two hours." Read more of this story at Slashdot.
