Bloody in another thread posted:select, where, aggregate are map, filter, fold btw, thanks for the linq rosetta stone. i couldn't see past the weird sql-like names and i actually am using it now that i understand what it is. also got to actually write some c# logic today and it feels so good. (gently caress javascript)

what is doforall and how does FirstOrElse differ from firstordefault

FirstorElse would let you specify a value instead of the default one. DoForAll would call an action for each item in the list. I presume, at least.

First thing he asks; can I export this (the backlog) to excel "can i export this to excel" means "im going to type things into excel and expect it to cause things to happen in the outside world, because im a fucker who thinks its acceptable to have no idea how the tools crucial to getting my jobs done work, like if i thought cars ran on happy thoughts so felt justified in chewing out the dealer every time i ran out of gas on the side of the road"

the only acceptable response to "can i export this to excel" is "yes, in the sense you can also advocate for the genocide of minorities. it is an option available to you as a sentient being"

garbage-nn is now definitely capable of learning it just is either really slow at it or i had a piece of my training set generation hosed up or something idk. with some liberal reinterpretation of the book i've gotten a 65% success rate on digit recognition and rising as i type. go lil garbage-nn go! 70%! its going!

wait, how is this theoretical DoForAll you guys have been talking about different from Select()?

Select is pure, DoForAll is probably intended to have side effects

What's the use case for "DoForAll" over consuming the enumerable in a foreach?

you are really really not supposed to have side-effects in a Select this is why ForEach doesn't actually exist. it's not an oversight by the devs, it's "lol lazy side-effects. let's at least try to keep them away from people" use a for each loop because it is strict. lazy side effects are almost certainly not what you want.

just the smallest point: any exceptions thrown in a lazy list will probably escape a try/catch block they throw when they get evaluated and if that's not inside the block then whoooooops gently caress you and that's just language semantics and doesnt even touch on confusing behaviour when you try to actually do things with them. don't use ForEach people.

gonadic io posted:just the smallest point: any exceptions thrown in a lazy list will probably escape a try/catch block that's actually not a problem with ForEach, because again, it's an extension of List<T>, not IEnumerable<T> but yeah don't put side effects in anything lazy, debugging that is a nightmare

oh i forgot that Lists are not lazy but IEnumerables are. my bad. everything i said doesn't apply to strict collections (but then chaining map and filter etc together are worse on strict collections soooo)

logback and slf4j both seem really cool. does that mean I'm correctly doing the java?

yeah they're kind of the current standard for java logging and there are slf4j bridges you can use to replace stuff like jcl or log4j if other dependencies were using them.
