'Steve Jobs In Exile' Remembers the Birth of the Web and 'Making Unix Taste Sweet'

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

"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.

Failing CS Grades Soar At UC Berkeley As Professors See Greater AI Usage

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.

This mini PC with the latest RISC-V SoC might actually be worth it

RISC-V has been in the "promising" phase for a long time now, especially for general purpose computing, never really breaking through into the mainstream in any measurable way. While I think that breakthrough is still relatively far away, we now do have newer RISC-V SoCs on the market supporting the RVA23 baseline RISC-V profile. One of them is the SpacemiT Key Stone KЗ, which promises to deliver a massive performance increase over previous RISC-V offerings. It's exactly this chip that's finding its way into complete, turnkey mini PC solutions, like this one from a company called Firefly. The base model comes with 8GB of LDDPR5 RAM and 128GB of storage, at a price of about €300 or so (there's also a 32GB/128GB model at well over €600). This is the first time I'm looking at a complete RISC-V solution where I feel like it might actually make for a good moment to jump in for us enthusiasts. No, the performance won't rival anything Intel or AMD has to offer, but it seems capable enough for a lot of day-to-day tasks, and I'm curious to see just how far along the Linux world is when it comes to RISC-V support. It's not part of our current set of fundraiser incentives, but if you'd like to see this RISC-V mini PC reviewed here on OSNews, you can always donate and add a note that you specifically want to see such a review (so I can gauge interest not just from our few commenters, but also from the more than 99% of our readers who only lurk).

When su replaced login for becoming another UNIX login

I've mentioned it before, but Chris Siebenmann is basically the Raymond Chen of the UNIX world, and today he's filling that role perfectly once again. I recently read Simon Tatham's Nitpicking the shell history scene in Tron: Legacy, where one thing that surprised Tatham was the film using 'login -n root' to become root instead of 'su'. This surprised me because I found that perfectly ordinary, and this turns up both a bit of Unix history and a difference between modern Unixes. Plain 'su' can let you become another user, including root, but what it explicitly doesn't do by default is create a new login shell for that user. If you do 'su root', the new root shell normally inherits most of your environment, your current directory, and so on. Sometimes this is what you want and sometimes you really want a new login environment, and originally in Unix how you got the latter was to run 'login' from your existing shell session (and this meant that login was setuid root, like su). ↫ Chris Siebenmann Unsurprisingly, this distinction has persisted to this day in various UNIX-like operating systems, but in different ways. Some maintain the explicit distinction, while others have more or less standardised on using su for both use cases. It's an interesting bit of UNIX archeology.

Roku launches open-source embedded Roku LT OS

Roku, the company that makes TV boxes and sells ad space based on your usage patterns, has released its remote control operating system as open source - and by remote control I don't mean robot stuff or whatever, but actual remote controls, the thing you use to control your TV or whatever from the couch. Roku has announced the official availability of Roku LT OS - a lightweight, highly deterministic open-source operating system that is already used in our industry-changing Roku remote controls. In addition to high-performance automotive platforms, Roku LT OS is designed to be accessible to the broader developer community. The operating system ships with native support for the ESP32 platform, a highly popular SoC among hobbyists and makers. Because ESP32 development boards are widely available online for just a few dollars, developers can get started with Roku LT OS with minimal hardware investment. ↫ Roku's developers blog As far as I can tell, this operating system is entirely new and not based on Linux or something else, but the available documentation is light on details so I can't make much more out of it. Regardless, it's nice to have another open source embedded operating system.
