Like, what would you expect a class named "CloneFoo" to do? create a copy of Foo right? Wrong. CloneFoo was instanced to access its methods that create lists of CloneFoo and these lists are actually the lists of things that you might want to clone an instance of Bar on to

java 8 has streams. just as good as linq .collect(Collectors.toList()) at the end of every pipeline is a bit wordy though. on the bright side you can collect to your own collection classes, such as Guava's immutable collections.

java streams are not great cause the function names are crap compared to linq.

cis autodrag posted:ya that's hungarian notation. were required to use it in all our vb6 code here because vb6s intellisense suxxxx yeah this was written by former VB6 devs I think so that would explain it. i wish the Hungarian guy that used to work here was still around so I could blame this on him somehow Possible next horror, every single class inherits from a base that manually specifies destructors and these get called at seemingly arbitrary points, do we think this is: a) "that's the way we've always done it" b) this is really old and piles so much stuff into the session state that the ancient webserver it used to run on couldn't cope without aggressively throwing away objects c) nobody knew what the using{} statement was or possibly it didn't exist d) possibly a legit reason idk? I'm struggling to think why some classes would need to make explicit disposal calls but everything else doesn't. there are no unmanaged resources being used here btw Edit: e) 1337 hax

cis autodrag posted:for the record the "m_" prefix usually means "global variable" if that helps u at all in this instance it's indicating a private member that is then exposed through a public getter/setter combo except most of the time the methods called that populate the fields are just writing direct to the private field rendering the exercise completely pointless

Powerful Two-Hander posted:oh right sorry, whenever i see "global" i read it as the "available anywhere in the application" sense aka what i used to do in Matlab because i did not know what variable scope was ya, in vb6 there's this horror show where the first 200 lines of your class end up being all these private global variables that control way too much of your class's behavior. you can of course do that in any language, but vb6 practically requires it to get any kind of complex behavior out of the thing.

Share Bear posted:does that help? I'm trying to figure out what the curly brackets mean or imply basically you have a set (indicated by the {} brackets) each element of the set is a pair, containing the xi vector and the corresponding data point yi. it doesn't actually have any deep meaning or anything, you should probably read forward until they start actually doing something with that data. once you know what they're trying to achieve, the representations chosen will make more sense

Hungarian notation was in the coding standard here when I started and I never really questioned it because it seemed fine, but now I'm kinda questioning if it's worth it. I mean I guess it's a bit redundant since the compiler is checking your types

Jabor posted:basically you have a set (indicated by the {} brackets) instead of adding a column to the matrix like I said before, it kinda feels more like this set represents a function f where f(xi) = yi. in naive set theory you start defining relations as sets of pairs and then you define functions from that. https://en.wikibooks.org/wiki/Set_Theory/Relations#Relations this is probably not that important, like Jabor said you should just focus on where they're going instead of the particularities in the notation

I mean I guess it's a bit redundant since the compiler is checking your types The idea behind Hungarian notation is that it makes incorrect code look incorrect. And also - irrespective of whether that first part is true or not - that nobody ever commits incorrect-looking code. It's stupid, is what I'm saying.

ThePeavstenator posted:it's me, the guy who has his IDE automatically generate getters and setters for every member .net MVC will fail (and won't tell you why either) to bind data if you don't have a getter and setter to indicate it's a field or whatever it is, so you have to pepper {get; set;} all over the place which i don't like but at least means you can refactor easily later. and that is still not as bad as having 50 lines of properties and their getters spammed everywhere

hi, am I the terrible programmer? It's convention where I work to prefix class data members with 'm_' and I didn't think it's that weird. Similarly, static variables typically get 's_' prefixes. This is all C and C++ stuff.
