Any library you would like to recommend to others as it helps you a lot? For me, mapstruct is one of them. Hopefully I would hear some other nice libraries I never try.

Need help navigating the Java ecosystem (coming from C++)
Martin Thompson is one of the leaders in that space: his blog is a really great place to start. His Agrona library is a bunch of high-performance data structures, which you can use directly, but which can also serve as examples of writing such code.

WritableImage and real-time ray-tracing. I need help!
ByteBuffer methods have quite a bit of overhead. You could further try to (1) writing to a byte[] first and then using the put(byte[]) method, or (2) use sun.misc.Unsafe::putByte (maybe try with Agrona's DirectBuffer and copy the necessary lines if need be).
- Are you interested in learning about low latency zero allocation programming?
