python didn't seem to have any inbuilt way to flatten an arbitrarily nested list down to a single list which is dumb as poo poo

or i guess you only recurse if you're given a list, otherwise just return the element this is a gonadic io fucked around with this message at 17:53 on Oct 9, 2015 |

Barnyard Protein posted:i could have done it in a nice way with a scheme or racket, a smarter person maybe could have done it better with java8. but java8's functional interfaces don't allow for functions with more that two inputs. Not sure about your specific case, but you can define your own interface that has a method with three arguments and label it with @FunctionalInterface , and Java will then happily allow you to use lambda expressions for that interface.

A monad is a space burrito. By which I mean it's just a type and three functions (map, join, and pure) that have particular signatures and respect the monad laws, plus some syntax sugar.

For real though it's: can you define singleton and flatMap for your data structure. If yes than it's a monad if no then it's not.

not terribad programming related, but relevant because CEO asshat and firing an entire engineering team: "Volkswagen's US CEO testified Thursday that the decision to use emissions cheating software was not made at the corporate level. Instead, it was 'software engineers who put this in for whatever reason,' Michael Horn told a congressional panel that is investigating the scandal." http://arstechnica.com/tech-policy/2015/10/volkswagen-pulls-2016-diesel-lineup-from-us-market/ i rofl'd.

i wouldn't say triggered, i was loving pissed. i am wondering about the laws there about that sort of thing, and what if some asshat pulls this in the united states and what laws could protect the engineering team.

there are whistleblower laws but lots of times whistleblowing leads to you being arrested as a terrorist. since its vw they could probably have told the EPA and been fine cause its not like its ford or chevy.

gonadic io posted:ya, no wannabe functional langs like scala, f#, etc stop you from mutating objects inside supposedly pure data structures. python's documentation on this says cahins.from_iterable is the preferred way: http://docs.python.org/2.7/library/functions.html#sum x = [[1, 2], [3, 4], [5, 6]] list(itertools.chain.from_iterable(x)) which is the equivilent of saying [ for x for x in x for x in x].
