The answer was unremarkable, apart from it mentioning in conclusion that it knows I previously used a tool called Alembic: Cool, it's starting to remember things about me. Let's confirm: Ok, maybe not yet. However, clicking "Show thinking" for the above response is absolutely wild: I know about the “Personal Context” feature now — it’s great.

This was a stunning result delivered after years of painstaking analysis. It’s not a bullet-proof result, but it doesn’t have to be to make our lives more interesting. I know I’m late to the party on discussing this. And it’s okay, because 1) there’s a lot to unpack in this kind of result and I wanted to take my…

💥 Explore this trending post from Hacker News 📖 📂 Category: 📌 Key idea: Introduction​ In our 0.5.0 release blog post, we announced that work was underway on a complete rewrite of Apache Iggy's core architecture using io_uring with a thread-per-core, shared nothing design.
