[@TheBuzzSaw]

The argument against generics is a strange one. My love of generics in other languages has little (nothing?) to do with inheritance or subclassing. I want my data structures to be strongly typed; that's all. I want to be able to create a ConcurrentRingBuffer or whatever. Go didn't let me do that. I also just don't understand this arrogance. (Yes, it's arrogance.) The language creators kept the power of generics for themselves. Go has generic arrays, maps, and channels. If generics are so terrible, why not return to the Java 1.0 days where arrays and maps just use Object for everything? OBVIOUSLY, strong typing is a good thing.

[@spell105]

I'd rather a language creator is arrogant and sticks to a vision and design philosophy, than for a language to throw in every feature ever. You wanted strongly typed generics? C++ is right there for you.

[@jonaskoelker]

> The argument against generics is a strange one. It's because it isn't one. I didn't notice a single thing to do with generics in that section of the article. It was 100% an argument against inheritance, which was not what was asked about. The word 'strawman' springs to mind-or, more charitably, 'misunderstanding'. Of course, if I go with the charitable interpretation I conclude that Go is designed by people who don't know the difference between inheritance and generics.

I don't agree, adding atomics to C++ (and the memory model in general) is the best decision ever made by C++ committee. This solved so much broken code and allowed us to write code that is portable on x86_64 and arm platforms.

[@EmiNNsoNify]

Quick question - what was the big problem with porting before atomics? Asking because the Linux kernel is written in C and is by far the most ported project ever.

[@vadzimdambrouski5211]

​@@EmiNNsoNifyConcurrency primitives in the Linux kernel are not portable by definition. If you try to use them in some other project it won't work because they rely on specific compiler flags and/or make assumptions about the kernel environment which may not be the same for other projects. Also before introduction of the memory model a lot of gcc optimization passes broke and miscompiled the concurrent code. Because without a memory model it's not possible to answer if a specific optimization (which could be perfectly fine for a single threaded code) is not valid when executed concurrently from another thread.

[@EmiNNsoNify]

@vadzimdambrouski5211 @bbourbaki Okay, fair points! My point was more on the "Linux kernel is massive project which is in C and you don't see them yearning for atomics." Should have been more explicit.

[@esra_erimez]

My dad was a developer when C++ first came out. It was a transpiler at the time, it converted C++ to C then you compiled that. He remembers thinking it was a good idea at the time. But, it never evolved into what it could have been. It lacked standards such as an object model, libraries, etc. Java would come along and fix issues like these but at the cost of having to use a JVM with an interpreted language. C++ has too many traps and pitfalls and makes you have to program defensively.

[@isodoubIet]

skill issue honestly

[@totof2893]

You need to test modern C++. The language has really changed. Most error prone stuff have disappear. It still requires some discipline with beginner, but when you are used to it, memory issue become very rare. With the invention of RAII, managing ressources (not juste memory, but connection, file, etc...) is easier than Java/Python. With the notion of rvalue, you have the notion of move instead of copy which avoid putting pointer/reference everywhere like Java and Python do by default. Now every life cycle is related to the stack and thus automatically freed by compiler at correct time. Lambda makes easier to write functor and functional code. Constexpr enables adding logics and interface at compile time instead of doing virtual polymorphism. And all the nice addition like std::variant (a easy to use sum type), std::tuple, std::optional to better represent data instead of horrible void* or Java everything is an Object. Still Rust refined those ideas and does even better. For example, due to backward compatibility, C++ is copy by default. While Rust is move by default, which enables to hide the l-value/r-value concept most of the time. Rust is const by default, C++ needs to have const everywhere. And Rust has lifecycle check which is very useful to avoid multi-thread issue and dangling reference. Even if modern C++ has less and less memory issue, it can still happen when beginner code like Java in C++. Rust completely avoid that by throwing a compilation error. And the memory model of Rust is far better than C++ unchecked exception or Java checked exception because it is directly using the return value. It becomes very easy to combine with functional code.

Now, before you invent more types than in _Rust_ , remember the number $n$ of types you can make with $c$ independent criteria is $n=2^c$. This is already *too much* to pre-define in a programming language syntax. And also, keep in mind that, inside the binary machine, the only actual type is *positive integer* . *Any other type is simulated* by tagging some positive integer with purely *arbitrary* meaning.

As far as possible, without surrender, be on good terms with all persons. Speak your truth quietly and clearly; and listen to others, even to the dull and the ignorant; they too have their story. Avoid loud and aggressive persons; they are vexatious to the spirit. If you compare yourself with others, you may become vain or bitter, for always there will be greater and lesser persons than yourself. Enjoy your achievements as well as your plans. Keep interested in your own career, however humble; it is a real possession in the changing fortunes of time. Exercise caution in your business affairs, for the world is full of trickery. But let this not blind you to what virtue there is; many persons strive for high ideals, and everywhere life is full of heroism. Be yourself. Especially do not feign affection. Neither be cynical about love; for in the face of all aridity and disenchantment, it is as perennial as the grass. Take kindly the counsel of the years, gracefully surrendering the things of youth. Nurture strength of spirit to shield you in sudden misfortune. But do not distress yourself with dark imaginings. Many fears are born of fatigue and loneliness. Beyond a wholesome discipline, be gentle with yourself. You are a child of the universe no less than the trees and the stars; you have a right to be here. And whether or not it is clear to you, no doubt the universe is unfolding as it should. Therefore be at peace with God, whatever you conceive Him to be. And whatever your labors and aspirations, in the noisy confusion of life, keep peace in your soul. With all its sham, drudgery and broken dreams, it is still a beautiful world. Be cheerful.

I don't know that procedural programming is strictly more natural than functional, though some things are naturally sequential in nature and therefore procedural fits better for those. I think it really is an exposure thing, the classic example being to ask students how to make a peanut butter and jelly sandwich.

[@ThePrimeTimeagen]

this is a great thing to watch, but its not a great argument. recursive thinking is definitely not a natural format, procedural is something we do with a _LOT_ of brain filling in the gaps

[@LambdaCalculator]

​@@ThePrimeTimeagenThis is an apples-to-oranges comparison. Strict FP may require recursion, but most functional code out there doesn't explicitly use it (preferring higher level abstractions like map/fold/reduce/etc instead). To make it a fair comparison, you'd have to compare strict functional code with strict procedural code, which would look more like assembly and preclude much of the common usage of functions found even in a language like C. And obviously, even the strictest functional code still has elements of procedural style in the way function calls are arranged and executed sequentially (though Haskell does complicate that a bit more with it's laziness). Point being: the whole Functional vs Procedural thing is just a poor dichotomy all around. You can't really produce good code with just one or the other, because they never existed in mutually exclusive vacuums to begin with. Good code is eventually going to rely on both styles where appropriate. However, functional style building blocks do become more useful the higher up you go on the abstraction ladder. And I don't mean pointless java-style "abstractions", but rather layers in a properly segmented cake-like architecture, more like the abstraction that occurs when going from ASM -> C -> Python (ie. stratified design). Procedural methods become more limiting the further up you go in abstraction because they were designed to work with lower-level primitive values. Thus when you try to make higher level abstractions work procedurally, you're forced to expose a lot more internal implementation details to enable working with them, which means leaky abstractions, more cognitive overhead for the developer, and prevents the formation of properly stratified layers. You might think to yourself "That's absurd. I code procedurally all the time and can still separate everything well with good API boundaries". But if you look at the situation closer, you'll notice that the entire concept of an API boundary is actually more functional than procedural, because you're asking the API to do something for you as opposed to telling it how to do it (ie. a function call as opposed to a GOTO). Which goes back to my original point about there not being any actual hard-and-fast separation between the two.

My problem with GoLang has always been the insular design of it. After it got some traction there were a lot of (poor) comparisons of GoLang and Erlang from, IMO, people rather ignorant of one or the other language. After a while I recall some of the Erlang communities' criticisms of Go's designs got back to core architects. The issue, from the Erlang folks, was ... why goroutines? Over the past 40 years there had been a lot of research into concurrency models and a fancier coroutine mechanism built into the language was better than nothing but Erlang and other languages / libraries had really powerful concurrency models that seemed to be entirely ignored in GoLang's design. And as I recall the response was kinda like: "we didn't look into the topic. :shrug:" I don't like that at all. In an age when concurrency is more important to make easier than any time in history and you spent time to design a language with concurrency built in... kinda important to do your homework. no? Erlang isn't perfect but when it comes to concurrency and general simplicity I absolutely adore it. You can understand the whole language without much effort. Worrying about contention rather than how to create the concurrency in the first place is truly game changing and I've never built distributed services more easily. Add in a fast built in serialization/marshaling library and simple technique for handling out of VM IPC... it is just a pleasure working with. I wish other languages took more of the Erlang communities' ideas. And I wish GoLang would have had actors instead of coroutines. You have languages like Pony that tried to go in an actor like direction but didn't get much traction.

[@trapexit]

Just saw @17:20 "Go's concurrency model might be the best ever." Can't agree even a little. It's not bad but actor systems, and proper scaffolding (like Erlang's supervisor module), are so much better for wide scale concurrency.

@@spell105 "No one cares..." Checks major apps used across the OSS world written in Erlang as are critical apps in multiple fields ... Yes, no one cares. Elixir is not all that much more than a syntax change. The fundamentals of Elixir are the same as Erlang. They run on the same VM. They have the same actor model because the VM is purpose built for concurrency. For Erlang. Elixir never would have existed had it not been for BEAM VM and the fundamental designs built into necessary to accomplish what it sets out to accomplish. It is why other platforms can't do the kind of concurrency models Erlang has. Why the Java Erlang implementation failed. If you want to be able to create fundamentally different patterns you have to often do fundamentally different things. And even when they fail to catch on they can provide a lot of value to others.

I learned Go this month and have been able to do some incredible things in it already; I can safely say that it is my new go-to language for anything that doesn't require GUIs, and I plan to build some GUI applications with Qt to see if it can become my go-to language for GUI apps as well. Also, curse C++, we hates it. Nasty C-pluses ruins the code.

@@ssokolow I don't understand why JS and Python would be the correct language for Google use of C++. C++ is for long term software when you know exactly the concepts and want to write them in the code. Thus the compiler can do the check for you and catch most errors. the goal is to be correct by construction. Changing becomes slower when writing code but faster in validating it. Because most issues are found with the type system. it also brings performance and memory predictability, good when you want to industrialize your software by consuming less ressources. JS/Python enables writing incorrect code without any warning but a crash in production. And their VM makes it unpredictable and not efficient in term of performance and memory. Thus it is better to do POC and try stuff when everything is blurry. Or to write quickly disposable script to manage existing library/software. But if you build huge program with it, you will just con your clients with many support case for runtime errors.

[@homelessrobot]

Yeah. Ruby was the rust of my generation. back when people in the indie-lang space thought there was a right way to do OOP. I imagine we will eventually arrive at a similar situation for rust things where we are like "Yeah that was an embarassingly long and windy dead end."

I never looked closely before into go and it's syntax. and after watching video I wondered how it is possible that it has no generics but is strongly typed lang. I checked and found that it has in fact "map[keyType]valueType" that is look to me as built-in generic. and makes me think it has no way to define custom generics but has built-in ones

@@devnexen I doubt it will ever get into that area fully, thats why I said it's starting to look like a great language for everything not frontend or super low level stuff like OS. That being said and to answer your question it would require GO to have no garbage collection at all in order to be used for it. Thats why C and C++ were kings for the past 40 years of OS development, and languages like Rust and Zig are the candidates to go in there

Whait, I know it's an old comment, but how are functions in programming languages not functions in the mathematical sense?

Do you mean the possibility of errors makes them not functions?

[@j-wenning]

Very odd that there was just about 0 pushback on the statement "Go's claim is that minimizing programmer effort is a more important consideration," considering the fact that Prime regularly says DX isn't a thing. That's literally DX in more words.

i say that modern dx is the definition of "i am familiar with this approach" that on the other hand is the summation of the post claiming to pair down features into the minimum amount to make it the most effective. i can agree with that statement / little argue because of the totality of the article and my knowledge of go

Wait, you understand Rust borrowing system, but you don't understand rvalue references? The borrow checker is exactly the same as rvalue reference but with the compiler making sure you are doing it right

I think the problem is the name, borrow checker just checks borrow, but a rvalue reference? What the heck is a rvalue and why are you referencing it?

[@infastin3795]

​​@@elcugo"rtfm lol"

[@isodoubIet]

@@elcugo rvalue references make perfect sense apart from the fact that value categories are distinct from types and you can have an lvalue of type rvalue reference and vice versa. That is the single most confusing aspect of the whole thing. Conceptually though, it's actually pretty simple, it's an rvalue because it's the sort of thing that goes on the right hand side of an assignment, which is 'just' a way to detect when references point to temporaries.

[@elcugo]

@@isodoubIet I know what rvalue references are, but the explanation just gave sounds like technobable to anyone that isn't already entrenched into C++. Thinking about a better name I came out with "ownership transferring references" which isn't a great name especially since it isn't accurate because moves may or may not happen.

[@isodoubIet]

@@elcugo The problem with other more descriptive names is they lose accuracy. Maybe that particular ship sailed with std::move but an rvalue, to me, doesn't imply ownership will be transferred. It just means I shouldn't rely on the object living past the semicolon. I will never understand the lvalue - glvalue vs prvalue - rvalue dichotomy though. Seems pretty silly and inconsistent.

[@mike200017]

I think the answer is simpler than that. While trying to sell a new language to C++ programmers, the moment you pronounce the words "garbage collector" or "no RAII", you've pretty much lost 90% of them already.

[@bloody_albatross]

Never used Go, but I really don't like the implicit interfaces. That's almost like dynamic typing where you don't know what a certain type implements and when the interface changes how would tools help you with the refactor? Also generics are a must in any language that is higher level than C (which I see as high-level assembly).

[@infastin3795]

Go has generics since version 1.18, which came out last year.

[@bloody_albatross]

@@infastin3795 I know. I might have a look at it when there remains no code that casts through interface {}.

Neither Rust nor Haskell have inheritance, the complaint about type hierarchies are about C++ and (especially) Java.

[@spell105]

C++ and Java programmers have long moved on from type hierarchies, stop inventing straw men. C++ has embraced composition over inheritance 12 years ago before it was the cool thing, and even Java programmers know inheritance causes headaches, with Spring moving to remove most forms of inheritance from its code, preferring interfaces where possible.

[@paivacn08]

I know templates are terrible designed in C++, but the idea behind metaprogramming is good per se for me. Maybe generic as Java and Rust are just enough.

[@BosonCollider]

This. The point of a type system with generics is that static type systems may not give you more expressiveness than a dynamically typed language, but if you don't include generics they can definitely reduce expressiveness a lot. It isn't so much about taxonomy as just making many functions impossible to write.
