Lost Unix v4 Possibly Recovered on a Forgotten Bell Labs Tape From 1973

2 months 1 week ago
"A tape-based piece of unique Unix history may have been lying quietly in storage at the University of Utah for 50+ years," reports The Register. And the software librarian at Silicon Valley's Computer History Museum, Al Kossow of Bitsavers, believes the tape "has a pretty good chance of being recoverable." Long-time Slashdot reader bobdevine says the tape will be analyzed at the Computer History Museum. More from The Register: The news was posted to Mastodon by Professor Robert Ricci of the University of Utah's Kahlert School of Computing [along with a picture. "While cleaning a storage room, our staff found this tape containing #UNIX v4 from Bell Labs, circa 1973..." Ricci posted on Mastodon. "We have arranged to deliver it to the Computer History Museum."] The nine-track tape reel bears a handwritten label reading: UNIX Original From Bell Labs V4 (See Manual for format)... If it's what it says on the label, this is a notable discovery because little of UNIX V4 remains. That's unfortunate as this specific version is especially interesting: it's the first version of UNIX in which the kernel and some of the core utilities were rewritten in the new C programming language. Until now, the only surviving parts known were the source code to a slightly older version of the kernel and a few man pages — plus the Programmer's Manual [PDF], from November 1973. The Unix Heritage Society hosts those surviving parts — and apparently some other items of interest, according to a comment posted on Mastodon. "While going through the tapes from Dennis Ritchie earlier this year, I found some UNIX V4 distribution documents," posted Mastodon user "Broken Pipe," linking to tuhs.org/Archive/Applications/Dennis_Tapes/Gao_Analysis/v4_dist/. There's a file called license ("The program and information transmitted herewith is and shall remain the property of Bell Lab%oratories...") and coldboot ("Mount good tape on drive 0..."), plus a six-page "Setup" document that ends with these words... We expect to have a UNIX seminar early in 1974. Good luck. Ken Thompson Dennis Ritchie Bell Telephone Labs Murray Hill, NJ 07974

Neurodiverse Professionals 25% More Satisfied With AI Tools and Agents

2 months 1 week ago
An anonymous reader shared this report from CNBC: Neurodiverse professionals may see unique benefits from artificial intelligence tools and agents, research suggests. With AI agent creation booming in 2025, people with conditions like ADHD, autism, dyslexia and more report a more level playing field in the workplace thanks to generative AI. A recent study from the UK's Department for Business and Trade found that neurodiverse workers were 25% more satisfied with AI assistants and were more likely to recommend the tool than neurotypical respondents. [The study involved 1,000 users of Microsoft 365 Copilot from October through December of 2024.] "Standing up and walking around during a meeting means that I'm not taking notes, but now AI can come in and synthesize the entire meeting into a transcript and pick out the top-level themes," said Tara DeZao, senior director of product marketing at enterprise low-code platform provider Pega. DeZao, who was diagnosed with ADHD as an adult, has combination-type ADHD, which includes both inattentive symptoms (time management and executive function issues) and hyperactive symptoms (increased movement). "I've white-knuckled my way through the business world," DeZao said. "But these tools help so much...." Generative AI happens to be particularly adept at skills like communication, time management and executive functioning, creating a built-in benefit for neurodiverse workers who've previously had to find ways to fit in among a work culture not built with them in mind. Because of the skills that neurodiverse individuals can bring to the workplace — hyperfocus, creativity, empathy and niche expertise, just to name a few — some research suggests that organizations prioritizing inclusivity in this space generate nearly one-fifth higher revenue. "Investing in ethical guardrails, like those that protect and aid neurodivergent workers, is not just the right thing to do," said Kristi Boyd, an AI specialist with the SAS data ethics practice. "It's a smart way to make good on your organization's AI investments."
