Facebook had a working spam classification system, and they replaced the data dependency graph engine with Haskell as a performance experiment. It's not to do with failing open or closed. Note that they hired the inventor of GHC Haskell's concurrency engine to do it, and he is not available to work at the company :-)
- artemisyna 7y agoEhhhh I’ve heard the predecessor engine had much to be desired, so it probably wasn’t only just the performance bit. That said, I could see performance (in addition to execution guarantees) being part of the factors. Sorry, not parsing the last sentence - what do you mean by “he is not available to work at the company”?
