Nomnom Cookie posted:im kinda pissed at java guys, they act like gc is super cool and everyone should use it and then when your heap gets over a couple gigs they're like "oh, you were going to *use* that heap? lol sucks to be you". at this point it looks like my best option is to break the one monster jvm into a bunch of little ones that can full collect independently and do something dumb to serialize requests to each baby jvm. all because I'm too dumb to manage my own memory and don't get to have memory pools how big is your heap? have you looked into azul

there's pretty much no limit to how much heap we could use because an expensive request will tie up 10GB of heap for several minutes (reducing heap usage is possible but not feasible in the next few months and poo poo is broken now, soooo). 64GB isn't enough for peak usage but it's enough that we're better off bouncing the server than letting it do a full GC because any requests from the front end time out before the gc finishes i'm talking to azul and am currently at the "tell us everything about your setup and problem so we can decide if we think zing will help" stage

that's actually not a horrible strategy; spin up worker vm's with huge heaps every time you need to run a job and reclaim them immediately when the job is complete. there's other mechanisms i heard about from azul like using some huge bytebuffer as some kind of scratchpad and never letting go of it but i've never had to go above ~ 8GB of heap and definitely never needed to gc that much so good luck i guess :/

btw, in javascript typeof null being object makes as much sense as typeof NaN being number. (both are correct)

what's bad about coffeescript anyway I don't web dev but I regularly hear about the landmines you need to dodge in JS, if I'm reading it right coffeescript gets rid of those and generates JS as its output seems like a good idea but as usual I'm probably underestimating the deep theoretical underpinnings required to pop up a dialog box in a browser

I feel like I enjoy whatever programming language I am using the most of at any point in time. Right now I like Ruby a lot, I like Java a lot (gently caress you owns), Python, C++, Javascript, whatever. I don't get why people don't like some languages, they are all good at poo poo Also I don't know lots of languages and have no urge to learn things like Haskell, mostly because I would rather smoke weed and chill than learn a programming language. I assume this makes me a bad programmer, but idc

RoR is a great prototyping environment, and there's easy (relatively easy) paths to porting it to something more performant. So the idea that you just want to get your poo poo up and functional asap and gently caress scaling until it actually becomes an issue is a perfectly reasonable choice in some circumstances.
