All the tech jokes today remind me of the best I can remember from my good friend, Piotr. 7 years passed, did it age well? blog.allegro.tech/2019/04/fr…

Java is setting the standards for #AI infrastructure⚡
Benchmark of MCP server implementations across 4 major languages puts #MCP #Java & #SpringAI at the top of the performance charts: sub-ms latency, highest throughput, and the best CPU efficiency

Just released a 100% Java GitHub #MCP using @springframework AI 🧠 You can now chat with your GitHub projects, search project files, commits etc
Code @ github.com/stephanj/GitHubMC…
I am pretty sure I was vibe coding in early 2000s when I was pasting PHP snippets and randomly changing things hoping it'd finally work.
Nothing wrong with that and having fun. Although, worth noting, I did not manage to create anything usable or working.
