1/4 Every time I present the same talk, it gets better. Sometimes because I spot things to improve. Sometimes because of great feedback from the audience. Check it out 🧵 cc @redis.io #javabubble

2/4 Next week at @devoxx.uk, I'll be giving my talk “Apollo 11: Rediscovering the Mission to the Moon with Vector Similarity Search, Spring Boot & Redis” for the 4th time. Since DevOps na Praia in Portugal, I’ve made two key updates thanks to feedback from @carlosenog.dev and Arthur Costa.
