Show HN: Ambient Context v1.0.0 (Missing context for AI assistants)

Hacker News - Wed, 09/09/2026 - 7:40pm

The other week I posted a concept to use the macOS Accessibility API to capture the text on your screen into a markdown file. It seemed to be interesting with 150+ github stars.

I've done a bunch of updates and packaged them into a signed macOS app.

One of the biggest changes was moving away from 'one context file per day' to three markdown files for apps, website, and messages.

I then run Andrej Karpathy's LLM Wiki process to turn into a simple knowledge base for the day. This is then used by a smarter model to synthesise into a daily overview.

Let me know what you think

Show HN: EmbedFlow –> Upgrade embedding models without re-embedding your corpus

Hacker News - Wed, 09/09/2026 - 7:34pm

I was playing around with embedding models and I realized the moving between embedding models on a large corpus can cause a huge backfill, as all of the previous documents would have to be re embedded.

embedflow tries to forgo that; it takes candidate documents from the previous index, and reranks them in realtime with the new model. It supports faiss, qdrant, and pgvector

people who have migrated large production vector indexes, would this be helpful for you?

Smashing Security podcast #484: How websites are tracking you with silence

Graham Cluely Security Blog - Wed, 09/09/2026 - 7:05pm
When a chap called Matt noticed his Bluetooth headphones wouldn't switch to his phone, he was surprised to realise the reason was a single AliExpress webpage sitting open in his browser - playing nothing at all, at zero volume. And yet somehow his hardware could hear it. Audio fingerprinting is one of the sneakiest tracking tricks on the web. Meanwhile, the intelligence agencies of the "Five Eyes" (not Five Guys) have got together and published advice on how companies should communicate after a cyber attack. The summary? For the love of God, stop calling every breach "sophisticated." All this and more in episode 484 of the "Smashing Security" podcast with cybersecurity expert and keynote speaker Graham Cluley, and special guest Danny Palmer.
