Building internet things

[Stephen Goldberg @sgoldberg]

We built an AI agent with semantic memory, semantic caching, vector search, and local embeddings — all in one runtime. No Postgres. No Pinecone. No Redis. No Docker.

24 lines of GraphQL schema. ~200 lines of JS.

Ask a question → 5s, full Claude call.
Ask it again (even rephrased) → 30ms, $0.00.

The HNSW vector index finds semantic matches and serves cached responses without ever calling the LLM. The more it's used, the cheaper it gets.

@hznus @openclaw @AlexFinn Guardrails:
- enable sandbox
- enable white-list if you want to run commands out of it
- read security doc
- use model that has best-what-we-have prompt inject defense
- run `clawdbot security audit`
- don't add it to group chats if it is your personal bot https://t.co/ePRwvUKWUc

SpaceX has released some new footage from the tower of the first Super Heavy booster catch yesterday. Absolutely epic shot.

(Interstellar music added by me lol)

Happy birthday to @fastifyjs that turns 8!

Neither @delvedor or myself had any clue that it would grow so much! Wow!

Doing the same with a smidge of tech debt. @DevNickity knows. @Duncanma too, but it’s complicated. 😅

Tomorrow marks the start of @NodeConfEU, where I'll be giving a talk on Day 2 looking at whether we can use HTTP for communication within the same Node.js instance.

Looking forward to seeing you all there!
