raminasi posted:I write plugins for a 3D modeler. explain why letting a dumb bug crash the whole modeler and losing my user's work is preferable to emitting an error message and aborting. Because if your dumbshit plugin is throwing an exception that it doesn't know how to handle locally, it's probably already hosed up the user's work. And unless you have a guaranteed safe rollback available, loudly failing is preferable to introducing silent corruption that the user might not notice until it's far too late to correct.

Jabor posted:Because if your dumbshit plugin is throwing an exception that it doesn't know how to handle locally, it's probably already hosed up the user's work this isn't true at all, though. the overwhelmingly common workflow is "user pushes button -> plugin crunches some numbers -> plugin updates in-memory document with results of number crunching." if an exception gets thrown during number crunching, then i can either tell the user "uh apparently that button doesn't work right now, you should probably email us about this" or just blow everything up around them, and i know which one my users prefer. (is it possible that an unanticipated exception indicates unexpected and incorrect mutation? sure. but in all the bugs i've found and fixed here, i can't think of a single one of those.) and i still haven't heard any explanation for who's supposed to be handling the unhandled exception if i can't do it. how do you even write a crash handler without being able to catch arbitrary exceptions? you've gotta get the stack trace from somewhere!

i am working on a go thing and i needed to store some common sql queries so i made a crappy cache object that i just passed around between things. then i realized it should probably be threadsafe so i added some thread safety and now i have basically rolled my own cache. anyhow, i'm not a total idiot so my conclusion is "i guess i need a cache" so I googled for the most popular go in-app cache thing and it has almost exactly the same api as the one i stupidly put together over the last day or two. like i will just have to change a few things. sometimes it's nice to be reminded that maybe i do know what i'm doing

fart simpson posted:you're not dumb if you don't understand abstractions by reading about them without actually using them imo agreed. this is why programming education is generally heavier on project work than lectures. i learned way more from implementing various abstractions badly over and over before getting a working program than from a week of lectures on, say, log-structured file systems.

Condiv posted:nah, scala is good things i hear about scala is that the performance overhead for some of the features it introduces come at such a cost at runtime (slow or unpredictable performance), that as you write scala in production it starts to resemble java. one with a nicer syntax i'm told, even if you do get quite close to java. the random bits bolted onto java are starting to lower the burden of writing in java now too. let's not talk about sbt this is a polite conversation

our logging configuration is broken again by ~~ something ~~ if i make a deliberate syntax error in logback.xml, mvn jetty:run will barf all over the console if i leave logback.xml as it was, i get a nice log about it being discovered and logging being configured the next output is code:i think this is the 4th time i'm doing this during this project after i get it working, if anyone breaks the logging again, i will literally flay them

in C: why does char ** cast to void * but not to void **, that's kind of annoying. is there some strict aliasing poo poo i'm supposed to be aware of i mean, sure i can throw a (char **) cast in there but this probably throws a warning for a reason and i'd rather not be visited by the spooky scary ghost of undefined behaviour

void ** doesn't make much sense to me since I'm guessing that someone would try to use it to keep track of a 2d array. however, you can't do pointer arithmetic on void pointers which also means you can't index into this structure. maybe i'm wrong on why the spec doesn't allow what you're trying, but that seems like a reasonable guess to me. edit: ^^^ that makes more sense ^^^ Star War Sex Parrot fucked around with this message at 17:04 on Jun 2, 2016 |

no, I get it, every line of code in C++ is, basically, a monad. it takes all variables, functions, etc. visible in the scope as inputs, and copies them to outputs, possibly modifying them, sometimes introducing new variables, sometimes erasing them if it's the end of a scope. I remember this from my computer science fundamentals course, every line of code being a function over all the variables that returns all the variables, with modifications, was one of the things I remember the best, but could never find a practical use for so I guess the "monadic" way to implement optional/nullable in C++ would be exceptions, which skip the "callback" (really a "callforward") and return the error value (the exception object, on the catch site). by making "monadicity" explicit you can do interesting things that normally require non-portable or privileged code, like scheduling/interleaving. I get it thanks tef, it was enlightening. you should give yourself more credit
