SIR PATRICK STEWART (1940-2026) Before everything else, Patrick was defined by being born and bred in Yorkshire, the proud county in the north of England which he loved to the end. You could hear it in his accented voice and in the stern honesty with which he told you what he thought and felt. Yorkshiremen have no truck with half-truths or avoidance of big issues. He wore his heart on his sleeve, which made him a man to rely on, to admire and in my case, love. We first met as ambitious young actors with the Royal Shakespeare Company half a century ago but we weren’t in the same productions. My first strong memory was a few years later, meeting him in the street in central London when he told me about an offer to take over a leading part in 'Star Trek'. “But Patrick think of your stage career in the UK. Do you really want to risk—getting lost in Hollywood for years and years?”. Well, he took the risk and thank goodness for us all that he did for not just his devoted Trekkies but film and theatre audiences, who marvelled at his using international celebrity to star in a string of cinema successes ('X-Men' of course) and in great classical plays by Shakespeare, Ibsen, Arthur Miller, Peter Shaffer, Pinter and Beckett at Stratford-upon-Avon, in London’s West End and on Broadway. America was his adopted home, where he met his adored Sunny who has cared for him through sickness and health, through thick and thin. But he never forsook his origins: and the proudest achievement of the most respected and beloved actor of his generation on either side of the Atlantic, was his appointment as Chancellor of Huddersfield University in Yorkshire. His farewell performance in 'Avengers: Doomsday' is yet to be seen. Ian McKellen 29 October 2026 Photo: University of Huddersfield

Could you share some insights for the next generation on how they can learn from your journey and follow a similar path? What different approach did you take that helped you stand out from others? Thank you, Sunil!

If you work in software, reconsider everything. Some things stay, some don’t. So much pre-AI is now sunk cost. I know you want to hear it’s all gonna be fine, you can just keep doing whatever you’ve been up to. That’s the only thing I’m 100% sure is false.

It’s quite incredible how bad ChatGPT is at plugins/mcps/whatever even with dots Muse is SO delightful in that regard

Let's talk a little more about Margaret Hamilton because she deserves it In 1961, Margaret Hamilton was tackling massive systems, having previously wrangled room-sized computers that blared like a foghorn whenever they crashed. Her fix wasn’t just to patch the bug. Everytime there was a crash, she took a Polaroid of the programmer who wrote it, and a note on the mistake. That way, if it ever happened again, they wouldn't be starting from scratch. They could note patterns and the last person who triaged that failure could help. This is a critical aspect of what she gave us. She didn’t stop at fixing errors. She studied their patterns so she could see them coming. She called them “the enemy,” and she meant it. Initially, when she was working on failure modes, higher-ups were errors wouldn't happen she actually named her program “Forget It.” But failures did happen. And her mindset, and discipline sent men to the Moon. Her Apollo software was built to expect the unexpected, and on Apollo 11 it recognized an overload mid-landing and kept the critical tasks running. Every postmortem, every bug tracker, every “let’s make sure this never happens again” carries a little of her in it. Thank you, and rest in peace, Margaret Hamilton 🚀

Very sorry to hear this news. 😥 I never had the chance to meet Margaret Hamilton, but her contributions to the flight software that got us to the moon are legendary. I love this image of her standing next to the printouts of the Apollo code.
We’ve lost an icon. Margaret Hamilton, a computer science pioneer best known for her work at MIT leading development of the flight software for the Apollo missions to the moon, has died at 90. Read about her legacy via MIT News: news.mit.edu/2026/margaret-h…

the harness community will soon learn the way of the bitter pill
This. People keep asking me for my setup. It's really just any harness, multiple agents concurrently, barely any skills, and using adversarial reviews. There's no magic sauce (or source!). The models are great out of the box.

a weird inversion with LLMs is the models improve faster than the tinkerers when i see people with custom workflows and setups they're all addressing problems that don't exist anymore the person naively using vanilla codex is more likely to be experiencing state of the art

When I built @kotn’s first store 12 years ago, I knew how to code and it still took me two weeks just to get to something OK, years to get to something I liked. We built the tool I wish I had back then. Here’s Canvas.

how can people have such bad takes
I’ve said it before and I’ll say it again: Rust is a *really* bad idea for any software you need to have working a few years from now (AI generated or not), or want to continue developing into the future. Not because Rust is ugly (which… it is). And not because Rust is, overwhelmingly, a cult (again… it is). But simply because Rust is still a moving target. The language is not yet “complete”… and neither is the compiler. Changes occur often enough (and in significant enough ways) to throw serious monkey wrenches into any sizable project. Once Rust stabilizes (which could happen quickly if the Cult of Rust actually wanted it to), this problem will quickly go away. Until then I will be sticking with C. Or C++. Or, heck, any language that is more stable than Rust.

When several people talk at once, a transcript can get messy fast. Our new Nemotron 3 Diarization model tracks who spoke when, even when voices overlap. It handles up to eight speakers, has 100M parameters, and is now available on @huggingface 🤗
