I listened to talk3 all the way through, and I have several problems with it. I'm suspecting that his experience predates agile and that everyone he's ever worked with went out of their way to show, by example, how non-agile development can go horribly wrong.
 
about 8 minutes in and haven't really heard much of a case for OO
first half of it sounded like a description of something similar to ECS, design wise
which i'd usually think of as more of an inversion of OO
 
@Donald.McLean yes he comes from LISP generation and assembly programming era.
Am not interested to align OOP with agile work flow.
 
Some of his overly broad generalizations of problems in OO are things that can go wrong in any kind of development, or relate to concepts that he has either never heard or dismissed out of hand.
 
OOP and agile are not mutually exclusive :)
 
4:35 PM
He said something in OO about method names being a lie. That does happen, and one of the most basic principles of agile is that when the name is wrong, you fix it.
 
Naming being wrong is one of the most common problems with any programming style. In fact, I'm just discussing it with our QA right now.
In this case, it's DB columns being named stupidly.
So, no fix (except going forward with new tables) because it would cause downtime.
 
In this comment, one of the reviewer says that haskell follows the same approach
 
However, in that same section, he mentioned something about the work actually being performed elsewhere, and that often happens when you have an API and some of the features are delegated.
 
So, let's take the basic premise he's arguing--OOP is bad.
So, if you don't do OOP, you have to find something to replace it with.
Because having no development standard is worse.
 
istm the gist of it is he likes separation of data and functionality as a programming style, but you can still do it with oo, and then bashes oo a bit just for good measure
 
4:39 PM
Granted. I just don't find any of his anti-OO arguments convincing.
 
Will it be procedural (I'd fire you if you tried that), functional (I love that, but it has to be done well, just like OOP), etc.
 
@Hosch250 I would say the opposite - they are complementary.
 
OO is not bad, but it's not as good as functional, when both are done well.
@Donald.McLean Correct.
OOP, functional, etc. They can all complement an agile work flow.
Waterfall is what kills businesses, but it also can complement OOP, functional, etc.
I actually like a mix of waterfall + agile.
 
@Hosch250 I would say that functional, OO, and procedural are all different tools appropriate for different things and the use a mixed OO/Functional language so that I have all of the tools and can pick the best one for each individual piece of code.
 
@overexchange i think the most general example of what he's talking about would be the sort of scenario where you have a Foo class that doesn't really do much besides hold some data, and a FooManager that handles everything you'd wanna do with a Foo
 
4:41 PM
Waterfall is the business vision of the final product. They have a specific endgoal of what they want.
 
Waterfall doesn't kill business, but it is a totally different mind set.
 
Agile is how they get there.
@pacmaninbw Waterfall kills businesses because a wrong turn at the start can't be corrected.
It's the difference between driving off a cliff or doing a u-turn.
 
Agile is more for the current web market.
 
@user11536834 and what about datatype? he mentions state_module, logic_module & datatype.
 
@Donald.McLean Yep.
 
4:43 PM
No waterfall and agile are project management systems. Bad planning and bad architecture is what killed business.
 
Personally, my favorite is API + functional, but I find OOP slightly better for UI and storage systems.
 
good question, i guess Foo would actually be the datatype, maybe FooManager is the state manager and something else entirely does the logic... i guess we need a better example than Foo
 
I learned from CS61A, that OOP is needed when a value has multiple states. value I mean business value, not the temporary variables holding the value for computing logic
 
@overexchange That's dead wrong.
 
i think the value of OO is in being able to delegate functionality instead of all functions being "global," more or less
 
4:47 PM
@user11536834 That's wrong too. You can have scoped functions.
Functions scoped to other functions. Functions scoped to certain modules that can only be used by visible functions within that module.
Lots and lots of scoping is available.
 
what language are we talking about here?
 
All of them.
I mean, yeah, some languages likely only have public functions. But none of the mainstream functional languages I've heard of.
 
I am trying to find an email conversation with my CS 61A teacher, as an evidence
 
hmm i mean something like doFooStuff(foo) vs foo.doStuff() ... doFooStuff(foo) is gonna resolve to whatever it resolves to regardless of what foo is, but foo.doStuff and bar.doStuff could do different stuff
 
@overexchange Those who can't do, teach.
@user11536834 You can do that in functional programming too.
 
Function overloads. You can have doStuff(foo) and doStuff(bar) resolve to different functions.
 
I learned CS basics from here CS 61A
 
yeah, for sure, but not so much in procedural
 
@user11536834 Correct. Procedural is more like assembly.
It's really not in use by high-level languages anymore.
It's good to know if you are working with C or lower, but by far modern languages aren't structured toward procedural programming anymore.
 
yeah, i didn't mean to imply oo was better than fp because of that, fp just does it in a different way
 
4:51 PM
Yep.
I find it best to know both.
 
and most of the assignments for CS 61A were reviewed by 200_success
this is how I learnt programming
 
right but you could still use a procedural style, i guess i was thinking more about the value of oo as a style over procedural
 
Yeah, it looks like a good course to learn programming structured toward OOP languages.
But it doesn't go deep enough to get into the OOP vs FP and when to use which--that's an architectural decision.
And I seriously doubt 200_success would say something like representing multiple business states can only be done with OOP.
 
the thing i can't really get my head around is how fp in multi-paradigm languages is really anything like fp in fp languages
 
@user11536834 TBH, it isn't.
 
4:54 PM
i mean like reducemap stuff is handy but fp languages are more like here are some rules, figure it out
 
C#'s functional pieces make it by far easier to use, but they don't come close to the F# features.
@user11536834 What do you mean by that?
Not sure, but is it more less documentation helping you learn the massive paradigm shift?
Because if you are in the middle of it, I'm happy to talk things through with you--I went through that a couple years ago, and I'm no expert, but I have some familiarity with it.
 
i'm thinking generally like how something like prolog works, you don't say "do this stuff," you define some state transformations, drop in some initial state, and let it solve for all possible outcomes
 
Oh, right.
 
i don't see anything like that in the fp parts of multi-paradigm languages
 
Multi-paradigm languages, in my experience, mostly support one paradigm at the program level, and multiple paradigms within the lower building blocks.
For example, C#'s new switch statement is really just a fancier way to write a lot of chained ifs.
But above the method level, it's still a full OOP language.
The non-nullable reference isn't really a dedicated functional piece--it's just that functional languages jumped on the bandwagon first.
 
5:00 PM
hmm yeah that makes sense
 
@Hosch250 I think switch in most languages is just a convenient way of writing chained ifs. Though some languages do it better - Scala's are very flexible.
 
so you could think of old java versions as not MP, but just OO (can't have anything that's not attached to an object), but newer javas as MP because you have lambdas and stuff now
 
@Hosch250 well he was also part of same course. I think he will say the same
 
Well, we could ping him and see what he says.
I mean, he's right here in the chat.
 
@Hosch250 By "non-nullable reference" do you mean "monoid"s (as used by programmers, not mathematicians)?
 
5:02 PM
Basically, yeah.
Maybe, Option, etc.
In C#, it's Nullable<T>.
 
@Hosch250 Scala has at least three: Option, Either, and Box.
 
FWIW, @overexchange, you might find this repository interesting. It represents multiple checkers variants (essentially, multiple businesses states) purely with functional programming: github.com/Hosch250/CheckersTreasury/tree/master/…
Anyway, GTG, now. Have fun programming.

@user11536834 java is actually procedural
and the object orientation parts are bolted on, just like the functional parts are
 
@Vogel612 I'd call it "imperative"
 
tomato tomato :)
 
methods are procedures
 
hmm, bolted on?
 
6:04 PM
@Vogel612 They are indeed, but I've never seen Java being referred to as a procedural language. en.wikipedia.org/wiki/Java_(programming_language)
 
@SimonForsberg my programming paradigms professor liked to do that
 
i guess any OO language is procedural at its core, but they are still considered OO languages, right?
 
shhh :)
yes, you're completely correct
 
i was thinking old java specifically as being "more OO" than others because of things like no top-level static classes, no functions that aren't methods, etc, basically everything is an object
except primitives
 
"no top-level static classes"??
there was a time before top-level static classes?

it's a tuple rewriting language i've been messing with
sort of an esolang deal
 
@user11536834 What part of that is the routine definition?
 
all of it up to "testing it out"
 
Hmmm.
 
there aren't any "keywords" in the language per se, it's just checking for tuples in a big list of tuples, binding some free variables on the way, replacing tuples with other tuples
the lines that look like multiply 3 and 16 as B are setting up the initial state (tuples in dataset), everything else is state transition rules
 
6:38 PM
@Mast And if you do, I'm reviewing it!
 
that somehow makes me wonder how I would multiply in prolog...
it's probably a bit easier...
 
pretty much like in c ;)
 
multiply (0, _) = 0.
multiply (_, 0) = 0.
multiply (1, X) = X.
multiply (Y, X) = X + multiply(Y - 1, X).
 
ahh that's not bad

True
 
6:50 PM
@Vogel612 now what about addition...
 
@user11536834 that can be resolved in a similar fashion
so long as you have a defined successor predicate, that is
 
addition is unary is easy, can just concat, but then negatives make it more difficult... if the numbers are encoded like +++ --- can recursively replace -+ and +- with empty string
 
7:25 PM
