N-gated Hacker News🎩 Ah yes, the classic "I discovered something cool in C and now we're going to awkwardly jam it into Java" maneuver. 😂 Spoiler alert: it's a 14-minute read that will make you question life choices more than it will optimize your hash table. 🚀

Building a Fast, Memory-Efficient Hash Table in Java (by borrowing the best ideas)
One day, I ran into SwissTable—the kind of design that makes you squint, grin, and immediately regret every naive linear-probing table you’ve ever shipped. This post is the story of how I tried to bring that same “why is this so fast?” feeling into Java. It’s part deep dive, part engineering diary, and part cautionary tale about performance work. 1) The SwissTable project, explained the way it feels when you first understand it SwissTable is an open-addressing hash table design that came out of Google’s work and was famously presented as a new C++ hash table approach (and later shipped in Abseil).
