Notion leaks email addresses of all editors of any public page

A serious privacy foot-gun: Notion has been silently exposing the email addresses of every collaborator on any public page — including people who never intended to be public-facing. If your team uses Notion for wikis or shared docs, audit your public pages now.

Changes in the system prompt between Claude Opus 4.6 and 4.7

Simon Willison does his usual forensic diff on Anthropic's system prompt changes between Opus versions, surfacing what's actually changed in the model's default behavior. Essential reading if you build on Claude Code or the API — subtle prompt shifts can break your workflows in unexpected ways.

The RAM shortage could last years

AI's insatiable appetite for HBM is creating a prolonged RAM crunch that will ripple through consumer hardware pricing for years. The 327-comment HN thread digs into whether this accelerates or stifles local AI adoption — directly relevant to anyone running models on Apple Silicon.

No. 05Creative SoftwareApplies to you

The creative software industry has declared war on Adobe

Affinity, DaVinci Resolve, and a wave of challengers are using Adobe's customer resentment as rocket fuel, rolling out free tiers and aggressive feature updates. The subscription-fatigue revolt is real and the alternatives are genuinely compelling now — worth reassessing your creative stack.

No. 06New Apple AppsApplies to you

Show HN: Run TRELLIS.2 Image-to-3D generation natively on Apple Silicon

TRELLIS.2 — one of the best image-to-3D models around — now runs natively on Apple Silicon without any cloud dependency. For anyone doing creative prototyping or 3D asset generation on a Mac, this is something you can clone and try today.

Prove you are a robot: CAPTCHAs for agents

As AI agents get better at solving human CAPTCHAs, the web is inverting the challenge — designing puzzles that only bots can pass to verify they're legitimate automation. A thought-provoking look at the infrastructure challenges of agentic AI workflows.

No. 08AI ToolsApplies to you

Claude Token Counter, now with model comparisons

Willison's Claude token counter now lets you compare token counts across multiple models side-by-side — an immediately actionable tool for anyone optimizing prompts and managing API costs across Opus, Sonnet, and Haiku. Bookmark this one.

No. 09Privacy & Security

SPEAKE(a)R: Turn Speakers to Microphones for Fun and Profit [pdf] (2017)

A resurfaces classic: researchers demonstrated that headphone/speaker jacks can be repurposed as microphones via audio driver manipulation — even on air-gapped machines. Disturbing and technically fascinating in equal measure, and newly relevant as physical-layer attacks get more attention.

No. 10Weird Science

The Bromine Chokepoint

Israel controls ~40% of global bromine production — a critical ingredient in memory chip manufacturing — making regional instability a direct threat to the semiconductor supply chain. A geopolitics-meets-chemistry explainer that puts the RAM shortage story in starker context.

Mythos di Anthropic: potere, rischi e la necessità di regole per la cybersecurity

Bruce Schneier's sharp critique of Anthropic's Claude Mythos — an AI capable of finding and exploiting software vulnerabilities, currently gated to ~50 large companies via Project Glasswing. He demands independent audits and broader researcher access before letting one private company control defensive AI power. Directly relevant to anyone building on Anthropic's stack.

Claude Codeで実際に起きたセキュリティ事故7選と防止策 #AI - Qiita

A Japanese developer catalogs 7 real security incidents that occurred while using Claude Code — including credential leaks, unintended file writes, and prompt injection via repo contents. Even if you can't read Japanese, the incident patterns are readable and the prevention checklist is worth internalizing.
