With a basic background in computer graphics, I found it took me about 4-6 months to understand and implement a paper like APIC from scratch. TaiChi's author, Yuanming Hu, apparently implemented that and 9 other papers in the same time. It probably helped a lot that he worked directly with the paper authors, but he certainly has been very productive. I really appreciate that somebody is implementing these papers in the open. It's incredibly useful to have a reference implementation available to study alongside the paper. Seeing the same thing in a few different ways is great for learning. His 88-line implementation of MLS-MPM is probably a little too much like code-golf, but when I expanded it out to 188 lines, I found it really enlightening.
