"Kind of funny" is professor talk for "I think this guy is hilarious, but I can't say that or my students won't listen to anything he says."

[@someoneelse5005]

came here to say this, I was the asssistant professor at the university and I was told to explicitly make sure when I am quoting something or referring something, not to state that it is in any way controversial, including being funny!

[@BasKeurprins]

Absolutely. I'd say it like that too, being a professor does not make you an authority on humor.

[@PisterLabs]

In theory I agree with the idea of "they all end in the same place," but the path you take towards your goal matters. If your perspective and tooling make the project unmaintainable or difficult to debug, that is a meaningful difference. Even through the project could reach feature parity across different paradigms, the longevity could suffer significantly if you are trying to force a perspective that doesn't fit.

[@xkali8119]

Now all that's left is to explain it in reaction video :D

[@connorskudlarek8598]

Do you by chance have some examples I could google? Or on your channel? (careful sending links in comments, the algorithm sometimes picks that up as spam) I'm having a hard time seeing why one perspective will be better or worse than another, even in a specific situation. It feels like that's more of a skill/architectural issue than it is a perspective issue. We each naturally will "feel" like OOP or FP are going to be harder to debug, maintain, or add to later. But is that feeling real (and something we can identify) or is that just us being more comfortable with one perspective over another? Is it that we just often implement the perspective poorly, or that a perspective is 'actually' poor? I can imagine, as Prime pointed out, someone who doesn't look at things through FP (like him) and doesn't really understand FP (like he said he doesn't) would implement FP very badly, and have a hard time maintaining FP code as they can't see the perspective themselves. Much like I still don't really get OOP. The only instance I can think of where pure FP is probably bad, is when data is going to get changed many times by being passed between functions. Like in neural networks, where you might pass billions of data points through functionA, then to functionB, back to functionA, millions of times. Copying that data to not mutate the state would be both memory and compute intensive for no real bug/safety benefit.

[@PinakiGupta82Appu]

@@connorskudlarek8598 I agree with that.

[@TheNeonRaven]

@@connorskudlarek8598 One good example where I find leaning more toward OOP is useful is game development, where there can be a lot of complex processes going on at a time, and objects make conceptual sense as references to entities in the game, that can each have their own actions and state. On the opposite end of the spectrum where I find functional programming a good fit, is data processing pipelines. You receive data is input, you run various computations on it, and you spit out an output. You don't want to spin up various instances of objects, you just want to process data. Procedural programming I find works well for most things in between, especially when working with typical applications where it's a lot of handling user input and rendering UI to a screen. You can of course use any of these paradigms for any of these scenarios, but they each have various niceties that make working in these particular scenarios significantly easier, in particular if you omit any sort of bias you may have from prior knowledge and experience. In the end, use what every you are most proficient in that can get the job done, unless you're trying to learn something else.

[@jeremiedubuis5058]

To me the real issue is abstraction not OOP or FP. What is really fun is that the basic concept of programming is abstraction. Programming languages are an abstraction on assembly which itself is an abstraction on electrical signals. The issue is having good abstractions, this is interface, or API. Building a good abstraction is incredibly hard, look at any small open source project with multiple developpers and insane amount of feedback arguing about what interfaces should be available. Whether a good abstraction you are using is OOP or FP doesn't matter at all, it is abstracted. To me, your project's architecture needs to be a really good set of abstractions. It requires time and thought to plan out and the sole purpose of that is to write the least abstractions possible on a daily basis because they are so hard. To take a simple example to me MVC is a model for abstraction that can be OOP or FP. Abstract the architecture and then when writing your models or your views or your controllers just go full procedural, your utils will almost necessarily be FP to be useful, your libraries will be one or the other and it really doesn't matter much as long as they work and have a great interface.

[@asdfghyter]

@@rando521 in my opinion the best way to learn FP is to learn Haskell, since it _forces_ you to use a pure functional style. now, how do you learn haskell? there are plenty of resources available, both free and paid books, youtube video series, video lectures, etc. and of course don't forget to actually try to write code with it.

[@SuperPranx]

The last big abstraction of abstractions we had to refactor was a dynamic table generator, which took a bunch of parameters from a bunch of places and generated table rows and cells in a data model in the backend, which was then used by the frontend to create a table. In the end we scrapped the old implementation, part of which was not even needed any more, and we wrote separate code for the different cases. Yes, there is some duplication, but I'd rather have that, than unreadable DRY code that it takes days to understand every time you need to change something or, heaven forbid, if you need to find an obscure bug.

[@tedbendixson]

I would say there's a pretty big difference between schools of functional programming and procedural programming. Many functional programming proponents also want to impose a bunch of constraints on state mutability, use of raw pointers, side effects, etc. If you want the constraints, you're in the functional camp. If you say to hell with the constraints, you're a procedural programmer.

[@gJonii]

Anyone programming in modern times with anything other than assembly subscribes to a ton of constraints. Say, structured programming, ie, not using goto, but function calls instead, is a constraint. You using objects is a constraint. It's a constrained way of structuring data/code. The interesting bit is that it is somewhat opposed to functional school of structuring data/code, but you can do both constraints, tho synergy isn't on your side there.

[@tedbendixson]

@@gJonii I meant more specifically the mutability/immutability constraints that tend to go with functional programming, the disavowal of raw pointers, that kind of thing. I agree that procedural has constraints, just different ones than the kind that functional programmers tend to adopt. And even within procedural schools, people disagree. Rust people don't do raw pointers. C people don't mind them.

[@Entropy67]

@@tedbendixson I guess that makes my code a combination of the two. Because its entirely possible to mix and match parts of your code with different styles, and sometimes it makes more sense - at least to me. I generally allow myself to figure out the structure of how I want to do something by messing around, then scrap it all and design something good from the start based on what I learned... when you have a second chance you can come up with all sorts of ways to optimize and make your code cleaner, more efficient, & more reusable, things you just wouldn't think of the first time without a better perspective of the problem.

[@colemanroberts1102]

​@@samuraijosh1595immutability doesn't require a certain evaluation strategy. Also, you can use arrays in immutable languages, so long as each element is only assigned a value once.

[@tedbendixson]

@@Entropy67 I do a similar thing. I assume the first version of a system will suck, but I make it anyway. Then, later on, if I need to make it better I'll do another iteration of it. Some systems are quite difficult to figure out, and I don't get there until the six or seventh time I build them. Generally speaking, programming ideologies are bad because nearly all of them assume you know what you're going to make before you make it.

Regarding 8:30. Isn't "the way to look at a problem" a mental tool? The way I see it: the first tool you use when solving a problem is contextualization, the way you choose to look at the problem. (i.e. which paradigm is best suited to solve said problem)

[@Provokant]

It's so telling that the professor skipped the part where you talked about oop and inheritance often beeing a unsuitable abstraction causing konplexity. Academia caused so much harm in practice especially with inheritance. They should really look more into what our problems in the industry are.

[@Muskar2]

It's so easy to buy in to OOP and inheritance. I wish the industry wasn't so dogmatic about it. And I wish that there were less gatekeepers among those who are proficient in both hardware understanding and procedural code.

[@itsrobelschwarz7248]

This is the realest take I've seen. Of the 4 computer science university courses I've taken, they all circle back to "OOP is the holy grail that will solve all your problems."??? Universities are psyops by the secret society of OOP to convince the population that there are no other paradigms.

[@BrunodeSouzaLino]

Academia is also responsible for selling the idea that functional programming is as easy to learn as its procedural counterpart whilst also maintaining an extremely high bar for entry. Haskell is 33 years old and there's not a single person in that community that's capable of explaining monads in a way that doesn't require you to already know what they are or have knowledge of category theory. The same goes for many of the complex parts of C++, Rust and so on. It's almost like people are in a pissing context to see who can craft the most complex solution just so they can bask about how smart they are.

[@RoyRope]

I think if I'd had to give a brief description of OO I think i'd would be a paradigm oriented around the communication of objects. Abstraction is everywhere, almost all paradigms can have that classification, you can(and probably should) have OO without inheritance, encapsulation similar to abstraction is very common for different paradigms(closures e.g.) and polymorphism can happen with functions to, and operators in reactive programming I think.

[@SynchronizedRandomness]

12:56 Use Common Lisp; you can abstract away inconvenient glue code so you don’t have to change existing abstractions to bring an unexpected use-case down to reasonable effort levels. And if you *do* need to change things, you can modify whichever aspects of the abstraction stack need to be refactored for your specific use-case, without having to modify the original code files or worry about entity-redefinitions breaking the language environment.
