The woman behind the Apollo software has died, and her story still reshapes how we see our work.
What the article says
- Margaret Hamilton died at 90. She led the MIT team that wrote the flight software for NASA's Apollo missions.
- She started in weather prediction work with Edward Lorenz, then moved to building America's first air defense software, where she got hooked on making software reliable.
- She joined the Apollo project as its first programmer and ended up running a team of hundreds.
- She later became a company founder and CEO, and received the Presidential Medal of Freedom.
- In her own words, management left them alone because software was a mystery, so they had to be pioneers.
What HN is saying
- Many commenters credit her with coining the term software engineering, and she explained she did it to win software the same respect as hardware. thread ↗
- One person says her error handling is why the crew could ride out the alarms before the Eagle landed instead of aborting. thread ↗
- A sharp correction: the famous photo shows printed output from an Apollo simulator run, not the actual flight code, though that was later hedged. thread ↗
- A skeptic asks what code she wrote herself versus what her team wrote, and says most coverage is fluff. thread ↗
- A developer feels wistful that today's work is mostly routine APIs, and gets a reply that interesting hard problems still exist, especially with hardware. thread ↗
Anthropic's new Haiku is far cheaper and faster, and Max subscribers get free API credit.
What the article says
- Haiku 5.5 is Anthropic's cheapest and fastest small model, aimed at summaries, classification and quick subagent work.
- It costs roughly 75% less than the old Haiku, with a higher rate once prompts pass a long length.
- It is the first Haiku with an adjustable effort setting, so you can trade cost against smarts.
- Sonnet 5.5 gets cheaper cache reads, and Max and Team plans get monthly API credit to build with.
- Big agentic coding jobs should still go to Sonnet or Opus.
What HN is saying
- Most see the pricing as a direct answer to OpenAI's cheap Luna model. The long-prompt cutoff is seen as low, but fine for small tasks. thread ↗
- The monthly API credit is loved by some, while others say it quietly pushes the Agent SDK off plain subscriptions and into billed credits. thread ↗
- Real-world results split. One team found it worse and slower than Haiku 4.5, while another found it the best value across a hundred models. thread ↗
- Simon Willison's pelican test shows steady improvement with effort level, though one reader argues the bike frames are still wrong. thread ↗
- A classification test found Luna cheaper in practice, thanks to leaner token counts and shorter outputs. thread ↗
A lone physicist wins the Nobel for building a telescope out of Antarctic ice.
What the article says
- Francis Halzen has won the 2026 Nobel Prize in Physics for his part in the IceCube Neutrino Observatory.
- The prize also credits the discovery of high-energy neutrinos that come from far outside our solar system.
- The page itself is a short announcement, so the detail here is inferred from the comments: IceCube turns a cubic kilometre of Antarctic ice into a particle detector.
- Sensors buried deep in the ice catch the faint blue flash given off when a rare neutrino hits an atom.
What HN is saying
- A popular explainer covers how it works: sensors in deep ice catch a faint blue glow from the rare neutrino collision. One reply clarifies the particles only outrun light as it travels in ice, not in a vacuum. thread ↗
- Many note it is the first solo physics Nobel since 1992. Others point out that a project with over 400 collaborators only works for the prize because it has a clear lead figure. thread ↗
- Several people who worked on IceCube chime in. The South Pole is wild for a few weeks, then flat, white and boring, and the job is mostly Linux admin. thread ↗
- A former thesis committee member says Halzen is a decent human being, and that the prize is for making IceCube actually happen, not just dreaming it up. thread ↗
- Funding was the hard part. You can't build a cheap demo in a nearby glacier, because the ice only gets clear enough kilometres down in Antarctica. thread ↗
ChatGPT now builds buttons, charts and mini apps inside its answers, and readers are split.
What the article says
- OpenAI's new GPT-6 for ChatGPT can answer with interactive screens, not just text. Think diagrams, forms, maps and little tools.
- Ask for a savings calculator or a dinner bill splitter and it builds one right in the chat. When plain text is enough, it should just give text.
- It can also start answering while it is still thinking, then add to the answer in stages.
- Paid tiers get it first, free tiers a day later. Work and Codex are not changing.
What HN is saying
- Many commenters find the visuals needless. A picture of a roast does not help when you wanted an ingredient list, and the style feels like it talks down to you. thread ↗
- A common suspicion is that this is a way to slip in ads, or simply to sell more tokens, since richer screens mean longer outputs. thread ↗
- The system card shows small safety regressions on self-harm and gore. One reader is alarmed, while others say those guardrails were overeager anyway. thread ↗
- People ask why chat gets GPT-6 and not the stronger 6.1. Replies guess at capacity limits and margins. thread ↗
- Some like it. One person finally gets checkable grocery lists, and another sees a real threat to Apple and app stores if chat conjures the interface. thread ↗
Photopea's creator can't get GitHub to remove AI-made, ad-free clones of his site.
What the article says
- The Photopea developer says people are asking AI to copy his site's code, strip the ads, and post the result on GitHub.
- Tens of these repositories exist, and some users now email him complaints about copies they thought were the real thing.
- He filed a takedown notice in early September and heard back a month later.
- GitHub said it could not confirm a violation of the anti-circumvention section of copyright law, and the repos stayed up.
- He suspects no human read his report and is weighing whether to hire a lawyer.
What HN is saying
- A commenter says he likely filed the wrong kind of notice. A standard copyright takedown is faster and gets less scrutiny than the anti-circumvention route. thread ↗
- Others push back that obfuscated code can still count as protected, so the first reading may not be right. thread ↗
- An IP lawyer says the realistic options are to pay a firm that handles this, or accept some losses. Doing it yourself will be a time sink. thread ↗
- Several people suggest making the app harder to run off his domain, but others say pirates beat that kind of check quickly and it is not worth the effort. thread ↗
- A GitHub employee turns up, asks for ticket numbers, and offers to follow up internally. Another commenter says posting on HN got a fast response for them too. thread ↗
- One camp says code copyright is a bad idea anyway. Another replies that copyright is what keeps open source licences enforceable. thread ↗
