was it actual (in-place) quicksort, or was it the silly "vaguely looks like quicksort but without the desireable performance properties" that's really easy to define in a functional language?

if you had specified any concrete numeric type there like Int instead of trying to get clever with your Integral a stuff, it would have worked

also the error messages arent great but it did tell you how to fix it if you dig through it: Could not deduce (Show a) arising from a use of ‘show’ from the context (Integral a) bound by the type signature for hello :: Integral a => a -> String at fizz.hs:1:10-36  Possible fix:add (Show a) to the context of the type signature for hello :: Integral a => a -> String In the expression: show x In an equation for ‘hello’: hello x | mod x 15 == 0 = "fizzbuzz" | mod x 3 == 0 = "fizz" | mod x 5 == 0 = "buzz" | otherwise = show x

That sounds basically like how react does it if I'm reading you right

If you are serious about learning Haskell (or even F#/Ocaml/ML), this is the best, but quite expensive, book for learning it.

someone sent an email that started with "bikeshedding time!" and im absolutely tearing poo poo up in there. amazing honeypot. what's the bikeshed version of "scrum master" or "thought leader" or whatever because that's me right now. or maybe I changed the conversation into discussion of important issues? it's impossible for me to tell.

somewhat unironic lifehack, spend more time criticizing other people's computer codes than you spend writing your own computer codes. its more fun, and people who don't know any better will think you're really smart. be sure to ask why they used this design pattern. and why didn't they use this other design pattern? ask where the architecture document is. don't read it! ask where the design document is. don't read this either! ask circuitous questions that could be answered by reading one of those two documents, then see if the in-person answer agrees with the documents. if they don't agree, use this as further ammunition to yosemite-sam your way up the software career ladder.

We had an "internal mobility" session today for teams in our line of business, where teams that are hiring pop down to people seeking prospective moves. I jumped down, and of course my manager is there talking to people about the available positions in our team, and I'm there cutting about talking to other teams about their positions lol I just wanted to find out what other stuff was going on in our area, I hope i didn't show him up by being there. He's pretty cool, so I'm thinking he won't take it as some kind of weird passive aggressive thing...hopefully

pointsofdata posted:you can also filter, group, and sort the data within wpf using CollectionView (I think) that's pretty sweet. i dont think ill use that, though, because im anticipating potentially hundreds of thousands of items being indexed so to keep memory consumption down i'd probably just load in the things the user has requested at that moment. not that the data being stored about each item is that much (location and tags basically), but why chew up memory you don't need to?

Yeah they definetly encourage you to move sround and get exposure to different areas and different tech. Unsurprisingly internal moves is a pretty informal process, probably just your current manager talking to new manager in a lot of cases. I don't think people ever successfully block transfers, but that's just speculation

Thanks everyone for the blogging advice. I hadn't really considered using tumblr, but that's actually a pretty good idea because it's so easy (and not a shitshow like wordpress). I'm gonna look a little more into github pages and static site generators, too.Charlie Mopps posted:If you are serious about learning Haskell (or even F#/Ocaml/ML), this is the best, but quite expensive, book for learning it. My one quibble about this book is that it starts off with a very dry chapter about lambda calculus. IMO lambda calculus is important for understanding functional languages at a deep level, but you don't really need it to get started and I feel like that chapter starts the book off on the wrong foot. Lambda calculus can seem pretty intimidating, and starting the book with a chapter on it makes Haskell seem more intimidating than it is.

piratepilates posted:also give medium a try, I see it a lot in my Twitter feed Both good suggestions. I've asked about Jekyll before in this thread, and it seems like most of its supposed problems come from the fact that it doesn't have incremental compilation, so compilation can take a long time for large websites. But this is a blog, so it probably wouldn't really matter for that. Bloody posted:consider html This is really what I should do, but I don't really trust my own ability to make things look pretty and clean. That's why a static site generator would be nice--it could make all of those decisions for me!

oh hey, lets just store literally everything for an x12 835 file in an array named %v, pass it around as an assumed global variable, and use 400 subscripts with hard coded string names that arent documented anywhere so you have to read the entire file generation code from beginning to end every time you want to do something. thanks whoever wrote this crap.
