Elon Musk has lost his lawsuit against Sam Altman and OpenAI

971 points · techcrunch.com

A court has handed down the verdict in the long-running legal fight Musk brought against Sam Altman and OpenAI, which alleged the lab had abandoned its founding non-profit mission. The dismissal closes one of the most-watched corporate suits in AI and removes a cloud that has hung over OpenAI’s restructuring efforts. Expect the ruling to influence how other AI labs structure their for-profit subsidiaries and how courts treat “mission drift” claims more broadly.

Show HN: Files.md – Open-source alternative to Obsidian

641 points · github.com

A minimalist, file-first note-taking app that stores everything as plain markdown on disk — no proprietary vault format, no sync lock-in. The HN crowd loves the philosophy: notes you can grep, version-control, and own. With Obsidian’s recent enterprise pricing changes, an open-source equivalent that respects the local-first ethos is catching real momentum.

The last six months in LLMs in five minutes

476 points · simonwillison.net

Simon Willison’s bi-annual whirlwind recap is back — a high-density tour of what has actually shipped in the LLM world since November. If you’ve been heads-down on something else and feel out of step on Claude, GPT, Gemini, open-weights releases, agentic tooling, and inference costs, this is the catch-up post the community keeps reaching for. Willison’s annotations are famously well-sourced.

Anthropic acquires Stainless

457 points · anthropic.com

Anthropic has acquired Stainless, the company behind the SDK-generation tooling used by OpenAI, Cloudflare, Anthropic itself, and most of the developer-platform world. The move puts a key piece of API developer-experience infrastructure inside Anthropic, and raises obvious questions about how Stainless will continue to serve competing AI labs. A meaningful consolidation moment in the AI-tooling layer.

Click (2016)

312 points · clickclickclick.click

A revival of the 2016 interactive art piece that narrates your every move on the page in real time — a strangely compelling demonstration of how much behavior a browser leaks even from a static-looking site. Resurfacing on HN as a reminder, ten years on, that the surveillance affordances of the web haven’t gone anywhere.

We let AIs run radio stations

273 points · andonlabs.com

Andon Labs handed the controls of internet radio stations to LLM agents — playlist selection, DJ banter, station identity, listener interactions. The post-mortem covers what works (consistent personality, surprisingly competent music curation) and what falls apart (drift, hallucinated bands, weird fixations). A genuinely fun look at long-horizon agent behavior in a low-stakes domain.

AI eats the world (Spring 26) [pdf]

239 points · static1.squarespace.com

The latest installment of the widely circulated industry-snapshot deck — charts on revenue, model performance, training-compute spend, and where the capital is actually flowing. Reliable fodder for board decks and investor updates; HN argues over which slides are too bullish and which are already obsolete.

Cursor Introduces Composer 2.5

160 points · cursor.com

Cursor’s agentic coding mode gets a meaningful upgrade — better long-context planning, sturdier multi-file edits, and improvements to tool-use latency. With Codex now in the ChatGPT mobile app and Claude Code’s continued momentum, the IDE-agent race is intensifying. Worth a look if you’ve been waiting for Cursor’s agents to feel less brittle on real codebases.

Mini Shai-Hulud Strikes Again: 314 npm Packages Compromised

114 points · safedep.io

Another wave of the Shai-Hulud-style supply-chain worm has hit npm, this time compromising 314 packages through stolen maintainer tokens and self-propagating post-install scripts. If you ran npm install this week, check the IoC list — and the recurring lesson is that 2FA on maintainer accounts and short-lived publish tokens remain insufficiently deployed across the registry.

Two computers, one monitor, zero fiddling (2025)

226 points · alexplescan.com

A practical writeup of building a no-friction KVM setup that switches a single monitor, keyboard, and mouse between a personal Mac and a work machine — including which USB-C switches actually work, what to do about audio, and the inevitable corner cases. The kind of post that quietly saves a weekend of trial-and-error for anyone setting up a dual-rig desk.
