i participated in a scala project once and every once in a while jenkins accuses me of breaking the build because sbt forgot how to sbt

So what is scalaz? I read the description on github and it says it's a bunch of stuff for function programming in scala, but I thought scala was already a functional language?

Bloody posted:scala might be good if you're using it as jvm-haskell. scala is probably bad if you're using it as java++ i'm afraid it's the other way around. scala doesn't (really) have functional composition and it's typeclass system is very different (and way more permissive) than haskell's. so much so that whatever compiler intellij uses will often choke (i.e. underline) on valid compiling code because it can't find implicits or the right resolution of the type class constraints

i've not actually used scalaz, i like the idea of more haskell-y type classes but otoh my boss loathes it with a passion due to the aforementioned operator hell. to be fair they're moving away from it, but it's too late.

LeftistMuslimObama posted:remember that poo poo I was bitching about yesterday? today I retrofitted it. 23 files in 3 directories, each 1000+ loc with one at 25000 loc. even using kdiffs directory merge feature to merge the current branch into the retro branch (hell no our svn can't do that on its own) it took 6 hours to get everything right because of the differences between versions. for some reason nobody else knows how to do this poo poo. everyone else who could do this got a different job

programming I am good at, geometry I am not so I need translate the world around me by the camera transform the camera starts at (0,0,5) pointing at (0,0,0) the cube is at (0,0,0) so we transform the cube by (0,0,-5) when drawing it to make it appear we are 5 Z units away from it but what if we want to rotate the camera, how do we calculate the new point that it's pointing at...

Luigi Thirty posted:programming I am good at, geometry I am not I don't have a totally clear picture on what you're asking and I apologize if I'm pedantic, but in general to transform 3D points under rotations you use a rotation matrix https://en.wikipedia.org/wiki/Rotation_matrix#In_three_dimensions or is what you're getting at more complicated?

actually yeah if you give developers a notion like visual studio solutions they're inevitably going to use it to mash hundreds of projects together without regard for which ones have anything to do with each other and which ones are really necessary to load in order to do the thing you're working on. just open up AllMyCompanysShit.sln
