stranger90··on Show HN: Vectree – Learn complex concepts through AI-generated interactive SVGs
Saw Vectree on HN—love the pgvector + semantic search approach for the concept graph. As you scale the Private Lab and user-generated concepts, you might hit latency/cost walls with standard Postgres. Rivestack gives you sub-4ms pgvector queries at a fraction of what you'd pay for alternatives. Worth a quick chat if scaling is on your radar—happy to run a benchmark with your query patterns.
stranger90··on Ask HN: How do you manage knowledge you accumulate as a developer?
Already building a vector search stack (Qdrant + embeddings + RAG) and clearly invested in the problem, but no indication they're experiencing performance pain or actively shopping for managed solutions. if you want to check (Rivestack.io)
stranger90··on I stopped treating email as a filing problem and built something calmer
I am a DevSecOps engineer and a parent, and over time I noticed how much email quietly consumes attention and creates digital clutter.

Not because email is broken, but because it mixes everything together and makes decisions harder than they should be. Things that need a reply, things you are waiting on, and things that are already done all look the same.

I wrote about why I started treating email as a decision problem instead of a filing problem, and how that led me to build a small tool focused on calm and clarity rather than features.

I am very early and mainly looking for honest feedback. If something feels off, confusing, or unnecessary, I would really like to hear it.
