Terabyte of RAM is my favorite because I choose to believe he had a perfect data model and was literally telling you exactly what he needed :D

In my recent work doing financial modeling (options, cryptos, other nonsense), I pretty much just try to cache absolutely everything with some arbitrary 1 week TTL and then continue to cache new data every day. Cache hits cause a 10% bump in the current TTL time delta. Kinda heuristic but whatever, works in most cases.

Any other funny stories? I always love these engineering horror stories. Have you looked at Julia at all? Would be interesting to hear if there's been an uptick in usage from the research community from a veteran research code surgeon!
