| 11:24 | <&jerith> | http://exercism.io/submissions/311a92d1b65549dfb967da80bf15e114 -- burn! |
| 11:26 | < Vornlicious> | And completely unhelpful. >:( |
| 11:26 | <&jerith> | In case that's not visible (I don't know if there's an auth block on it or something), it's a short Erlang program on which someone has left the comment "This is great Python." |
| 11:27 | <&jerith> | That particular commenter has left some rather more helpful comments on other submissions, at least. |
| 11:33 | < Vornlicious> | (also there isn't) |
| 11:48 | <@Pi> | I really should pick up Exercism again. |
| 12:12 | < Vornlicious> | I get pissed off at it because my instinct is to help everyone and I don't have that kind of time in the slightest |
| 12:27 | < Vornlicious> | Which pointed me at Rikki but that's in a language I don't know and I keep seeing complaints about |
| 12:28 | <&jerith> | Vornlicious: Go isn't a bad language. The complaints are mostly about how much better it could have been. |
| 12:28 | <&jerith> | (If it were really a bad language, people wouldn't care as much.) |
| 12:29 | <@Pi> | Snatching defeat from the jaws of victory can be a lot more emotionally wrenching than the other way around. |
| 12:29 | < Vornlicious> | 'course, I work in js a lot so it's not like, you know, being a bad language really stops me |
| 12:30 | <&jerith> | If you don't care about concurrency and are okay with copy/paste instead of generics, most of the problems go away. |
| 12:31 | < Vornlicious> | K I'll be fine then |
| 12:31 | <&jerith> | For this particular application, neither concurrency nor generics are likely to be an issue. |
| 12:45 | <&ToxicFrog> | jerith: don't forget shitloads of boilerplate for error hanlding |
| 12:46 | <&jerith> | ToxicFrog: Yeah, that's also an issue. |
| 12:52 | | Degi [Degi@Nightstar-ibr0nm.dyn.telefonica.de] has joined #code |
| 13:01 | <@abudhabi> | Hmm. I want to migrate my irssi to another server. What do I need to copy? |
| 13:09 | <&jerith> | Meh, Nucleotide Count requires some pretty awkward error handling. |
| 13:16 | <&ToxicFrog> | abudhabi: man irssi and see where it keeps its config and log files? |
| 13:17 | <&ToxicFrog> | Probably just ~/.irssi or ~/.config/irssi but it's been years since I used it. |
| 13:25 | <@abudhabi> | Thanks. |
| 13:56 | <&[R]> | TIL about the JS tilde operator |
| 13:56 | <&[R]> | Unary operator that adds one and flips the sign |
| 13:58 | < Vornlicious> | So, bitwise not |
| 13:59 | <&ToxicFrog> | So it- dammit, vorn |
| 13:59 | <&[R]> | Ah |
| 13:59 | <&[R]> | I was wondering WTF |
| 13:59 | | * Vornlicious knows his operators |
| 13:59 | <&[R]> | Forgot C had it too |
| 13:59 | <&jerith> | Assuming twos-complement integers. |
| 13:59 | <&jerith> | Which JS doesn't actually have, because numbers are numbers. |
| 14:00 | <&[R]> | Numbers are doubles yeah |
| 14:00 | <&[R]> | Up until you do bitwise operators on them, then they become 32-bit signed ints. |
| 14:01 | <&jerith> | They're turned into twos-complement integers for the purposes of the bitwise operation, they don't necessarily stay that way. |
| 14:02 | <&[R]> | Right, they're turned back into doubles the moment you do anything else with them |
| 14:02 | <@Pi> | Perfectly Sensible. |
| 14:04 | <&jerith> | AIUI, they're not necessarily doubles either. |
| 14:05 | <&jerith> | The implementation is allowed to use whatever representation it likes. |
| 14:06 | <@Pi> | Wibbly wobbly county wounty stuff. |
| 14:06 | <&jerith> | Indexing with floats is typically a bad idea, for example. |
| 14:17 | < Vornlicious> | You do get explicit number types in es6 |
| 14:18 | <&[R]> | ? |
| 14:18 | <&jerith> | I get the feeling ES6 is trying to be a real language.~ |
| 14:42 | <&jerith> | Heh, I've overtaken McMartin in Erlang exercism. :-) |
| 14:49 | < Vornlicious> | Well, typed arrests |
| 14:49 | < Vornlicious> | Arrays gosh |
| 14:59 | <&[R]> | Ah yeah |

| 17:39 | <&jerith> | McMartin: Robot Simulator looks like the first Erlang track problem that requires processes. :-) |

| 18:06 | <&McMartin> | jerith: Cool. I've noticed that some features are only introduced later; I had to use erlang:error for the first time in one of the DNA-related ones that wasn't the one you used throw in. |
| 18:07 | <&jerith> | Yeah, I complained about the annoying error handling in that one above.~ |
| 18:12 | <&McMartin> | I mean, I learned something, so that has value, I guess~ |
| 18:13 | <&jerith> | It definitely has value. I just didn't like it much. :-) |
| 18:13 | <&jerith> | (Exception handling isn't at all common in the Erlang world.) |
| 18:14 | <&McMartin> | I had a lot of trouble with the earlier ones because I was just letting unmatched cases crash with unmatched_case |
| 18:14 | <&jerith> | That's usually a good idea, unless you're expecting stuff you don't know how to handle. |
| 18:17 | <&jerith> | As an aside, it might be valuable to solve Robot Simulator twice. |
| 18:18 | <&jerith> | Start with raw processes and message passing, then do it again with a gen_server. |
| 18:18 | <&McMartin> | I need to find a good primer on OTP. |
| 18:20 | <&jerith> | There's probably a better Erlang thing now than when I looked a decade ago, but the Elixir docs are great for this. |
| 18:20 | <&jerith> | (I never really understood OTP until I read those.) |
| 18:28 | <&McMartin> | Yeah, that talk you linked me assumed I knew several things I didn't, really. |
| 18:29 | <&McMartin> | The high bit I took from it is that I should be using more transient worker threads in my designs. |
