>JavaScript
Accurate. Since ES6/2016, it's at least two languages in one. You can use classes and block scoping and statically-bound this, but the old misdesigned features are still there, and you can still use prototypical inheritance, function scoping and late-bound this. Also, the original JavaScript was at least three languages in one. It looked like Java, but it was also Eich's pet functional language, and it was also its own unique thing with its own weird shit like the scoping rules. There was always at least two ways to make an object. You could put the methods on the prototype or assign the methods to the object inside the constructor's closure. Now there's at least three ways because of ES6 classes.

>Go
Mostly accurate, but it also needs Rob Pike and Ken Thompson breathing down your shoulder and inflicting their pedantry and elitism on you and forcing you to do things the Right way and to use the Right indentation style and the Right documentation style and the go get approved source code repositories and that channels are the Perfect and Only way to do concurrency and to never leave unused definitions in the code, not even while testing, and that you're too stupid to use generics and to never question the garbage collector.

>Python
I get it, but "the forced indentation of code" has always been a superficial aspect of Python. Like Go, the real problem is pedants. Be prepared to argue for days about which of the billion ways of doing the same thing is the most """Pythonic.""" Also, you'd better be prepared to read PEP 8.

Also Python is really two languages that no one can agree on. Did you pick Python 2 or Python 3? Guess what? Both are objectively the wrong choice.

>>60327585

>>60327648
C++ can achieve this with concepts, or alternately by jumping through some hoops (though in that case it's admittedly not language-level). but at least the hoops aren't as bad as they used to be. i like C# generics/constraints a lot but unfortunately they do kind of fall apart at the line between primitive and user-defined types (and potentially types defined by third parties), since you can't implement an interface for a type you didn't author. also kind of a pain that you can't interface/constrain for operators. also template specialization is occasionally very handy despite being conceptually rather impure. for those reasons, there's still a solid number of scenarios where i'd take C++ templates over C# generics, despite the fact that (without concepts) they throw language-level type safety guarantees out the window

>>60327260
Java as a clean shaven businessman, because its the most professional language out there.

>>60327618
I'm gonna be the guy with the unpopular opinion here, but JavaScript has the right idea.

Traditionally -- in a compiled language -- an object's named fields are compile-time constructs whose meaning depends on the type as which the object is being interpreted. If you have a type in C that can be written as

struct {
   int i;
   long l;
}

Then the i and the l there aren't the unique strings they appear to be, they're actually plain old numbers that index the address of the object to which they belong.

A scripting language doesn't have to be compiled, so there's no good reason to preserve the illusion of compile-time constructs. Everything in JavaScript is dynamic, because it's a scripting language, so if the named fields of an object have to be dynamic, why not just make them as dynamic as they CAN be? Why NOT just allow putting new things into objects and taking old things out at will, as if they were some common data structure?

is it worth learning BASIC just as a little time waster?

So I see most OS is written mostly in C

why is the choice in C and not C++?

>>60328650
For starters, development of most (popular) OSes started before C++ was stabilized in 1998.
> Is it slower?
C++ is generally faster, thanks to templates.
> Maintenance carrying momentum?
Yeah.
> Is that a common sentiment that influences the decision as well?
Yes, most of the C-fanboys don't know C++ besides a couple articles on how C++ is bad they've read back in the 1990s. Modern C++ is nice and is a way better choice for everything.

>>60328650
historical reasons, c++ compilers became viable for bare metal programming not so long ago.

     return result;
}

I will get proficiency in C before I look at C++ again. I'd like to have the ability to not write the fat to have to cut in the first place.

>>60328923
another follow up question.

C++ seems to be C + stuff
why can't you just write clean efficient C that then when needed takes what is better from what is added on? The bloat of the language isn't that just choice in the end?

Great C ----> Great C++ after picking the bits you need from the supermarket of ++ ?

>>60328650
a lot of the code in a given OS probably predates the time when C++ became a viable option (and *really* predates a lot of the improvements to C++ which have made it much better/more viable than before). and a lot of that code has probably remained largely unchanged in perhaps decades, and has stood the test of time, in which case it wouldn't be very wise to sacrifice all that stability by going back and rewriting it in C++ simply for the sake of it.

>Is it slower?
C++ is certainly not slower (and can be faster in many idiomatic cases), unless you make use of virtualization, which an OS would almost certainly not do, especially when static polymorphism exists as a zero-overhead alternative.

>Maintenance carrying momentum?
this would be a factor. there are far fewer competent C++ programmers than C programmers, not because of differences in popularity/prevalence, but simply because it is much harder to be a competent C++ programmer. and incompetent C++ programmers could most certainly muck up or at least complicate a project like an OS

there remain many *very* dated conceptions about C++, like that it is not suitable for embedded development, which has been false from the start, and only become *more* false (in a way) over time as C++ has modernized (new features expose zero-cost or even "negative-cost" abstractions which have *technically* always been possible to achieve (with heavy use of templates/macros), but formerly not in such an easy/idiomatic way).

in all, there are legitimate reasons why it's the case with current OSs, but if one were to develop a new OS from the ground up, it would be foolish to use C over C++.

>>60328984
It looks like you've already made up your mind about C++'s "bloat", but the fact it, idiomatic modern C++ is easier to write and to maintain than the equivalent C code. Adding "++" to existing C codebase, and mixing C++ and C in general, is a recipe for disaster, and a sure way to make your code unmaintainable.

>>60328984
>The bloat of the language isn't that just choice in the end?
that's exactly it. C++ is a multi-paradigm language. you're not supposed to use every feature in any given program

what you'll find though is that, for a lot of programs, you'll be using more and more ++ features over time. in particular, professional C code makes use of a lot of macros that are better implemented as templates in ++

>>60329063
I'm sorry I'm ignorant

I have not made up my mind about anything its just I don't think im ready for c++ so my information about it is not the best. I feel like becoming adapt at C would lead to an adapt at c++

in general i think that most of the "C++ is bloat" people could calm down if they just
>don't use inheritance

and i think that's more of a commentary on inheritance than it is on C++. it's a bad, over-engineered abstraction for the majority of problems.

people tend to think of C++ as "C with classes" but the killer features are actually templates and RAII, because if you look at idiomatic C the things that are disgusting are macros and cleanup during error handling. you don't see a runtime polymorphic union in every C program, yet for some reason people are eager to introduce inheritance. i wish that C++ had a proper interface type distinct from a base class

describing C++ features as "bloat" is really only valid in the sense that the addition of features compared to C bloats the complexity of the language standard. the existence of those features does not arbitrarily negatively impact the runtime performance of C++programs. in fact, the vastly overwhelming majority of C++ features have zero runtime cost. the only one i can think of that doesn't is inheritance and related features (technically not even all inheritance, but rather virtualized inheritance), and it's entirely optional, and you only pay for it if you use it (in fact, "only pay for what you use" is a core principle of the design of C++). i only use it for the sake of simplicity in rare cases where it's particularly well-suited to my problem (that is to say when a problem is actually naturally well-modelled by a class hierarchy, which honestly doesn't come up much).

>>60329176
this. a given problem is generally better solved by generic programming than by inheritance. this has been made easier than before with the addition of recent C++ features

NOPE.

Guess I'll only learn c++ for this semesters course and then just drop that shit. I feel comfy with C and embedded stuff

>>60328028
>Whole-program-scoped globals shouldn't exist.
But if you use C, then without exactly one whole-program-scoped global, you can't emulate namespaces in a way that doesn't look like trash!

>>60327889
damn thats really slick

>>60330058
to be fair, K&R is also $50 for a new copy
publishers are just greedy jews

buy used if you must have a physical copy
do not buy international editions, they're fine for books you wish you didn't have to buy (college), but for reference texts, they're printed on shit quality paper and smell bad, the paper is NOT archival quality.

>>60330058
>>60330087

>>60330100
programming textbooks are the easiest textbooks to pirate, they're all online, many of them are old enough that they're not even in print anymore and the publishers don't care because they're not aimed at the university student anyway

>>60330100
Physical books are more comfy.

>>60329255

>>60330087
Just looked it up and I really paid 50€ for K&R. Thought it might have been 10-20€ less, but nonetheless I really needed K&R or atleast it was worth it (for me), since I only knew Java before.
And since I (atm at least) dont have the intention to do much with c++ I will only learn shit that is needed to get my course in uni done. Which all should be available in our library.
>>60330100
If you just want to hack something together or like me with C++ just complete a course in uni, than this is a good decision, you are right.
BUT if you _really_ want to learn the language you should go more in depth and understand (or try to) every single bit in it. And K&R does a really good job there.

>>60330305
>is eye strain a real thing?
If you stare at pure colors for a long time in your editor.

>>60330305
it happens as you age but is easily managed. probably not an issue if you spend less than 12 hours in front of a screen

>>60330305
It depends on your eyes. Some people have eyes that are fucked up in specific ways that make it a strain to focus on one thing for a long time.

Other people have eyes that let them stare at screens for hours on end with no problems.

>>60330376
So basically you staring at a screen with no breaks for 12 hours a day hurts your eyes, WHO WOULD HAVE THOUGHT?

>>60329742
>I mean, "they" is a pronoun so I should be able to replace it with an actual noun without changing the grammatical structure of the sentence, and "Chad are tall" makes no sense.
In the case of "they," this assumption is actually incorrect. The gender-neutral singular "they" is a plural pronoun for a singular referent. You use singular forms when referring to the referent directly, and plural forms when referring to them through their pronoun. However, as you may have noted in that past sentence, you don't pluralize the objects of the possessive, because even though you're using plural-form verbs, you're still only referring to one person, so anything that person has only one of is still only one thing.

>>60330426
It's not that it damages your eyes. You're just overusing your muscles in the same way that you would if you were constantly lifting things.

Some people have to focus one eye slightly differently than the other when they look at close up objects. Others don't.

>>60330484
>It's not that it damages your eyes. You're just overusing your muscles in the same way that you would if you were constantly lifting things.

https://www.youtube.com/watch?v=ckZlj2p8W9M

>>60330376
You have to keep the brightness of your screen at a minimum in dark ambient light and train yourself to never have your eyes focus too much on anything. Basically, if you ca'tn read something, zoom in instead of squinting. Also changing the temp color of your screens colors at night with something like f.lux helps a lot.

I state at a screen from the moment I wake up to the moment I go to bed and I don't have any eye problems whatsover.

Rust can do multiple return values too, it's just returning a tuple. Unlike Go though, it can also return proper tagged unions, which is MUCH better for error handling which is the most common application of multiple return values in Go.

Among the two, I would suggest Rust. However, I think I'll echo >>60328195
and suggest that you learn Haskell to broaden your horizons a bit first. Once you know C and Haskell, Rust will be trivial to learn.

It's more of a problem that 4chan made, The only reason it forces you to use V2 captcha is that you probably submitted your posts using V1 captcha, anything else would be a redundancy that's not really going to solve the problem.

oh right, theres a module for it though.

;)

with Ada.Text_IO;
procedure Wew is
    type Little_Element is range 4 .. 10 with Size=>3;
    type Nice_Expressiveness is array (1 .. 30) of Little_Element with Pack;
begin
    Ada.Text_IO.Put_Line(Integer'Image(Nice_Expressiveness'Max_Size_In_Storage_Elements));
end Wew;

Really made me think, senpai

Python infinitely more than C. C will just straight up break itself and everything around it if you're shit. A bad C programmer is equivalent to a fantastic Python programmer

Why is lisp such a shit.
Where's my takewhile, dropWhile, take, drop
iterate
I don't care how supposedly good your language is, if it doens't have a god-tier standard library, then it's obviously shit.

If you don't have correct programming practices with C you won't go far. So it's the total opposite anon. C has still the best documentation in the world.

Is this the power of old languages?

>>60333684
God bless Ada

In Java how do I update/overwrite a file with an arraylist?

I want to learn a language, but I don't really have any idea what I'd do with it. I have no projects I really want to do or anything I want to make. Is there a reason to learn to program if I can't think of a reason to learn to program?

You want to do something but you don't know why you want to do it?

Is this what young people are like these days?
They don't even know how to describe their feelings?

Pretty much. I'm bored and want to do something productive with my time and learn a skill for free.

The point of Lisp is you make your own subset and STD.

>>> from hash_table import *
>>> ht = HashTable
>>> ht = HashTable(701)
>>> ht.add(1)
>>> y = ht.search(1)
>>> y.value
1
>>> ht.delete(y)
>>> z = ht.search(1)
>>> z.value
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'NoneType' object has no attribute 'value'
>>> 

i did it! i won! implemented both linked lists and hash tables. are you proud of me?

>>60334540
Then you learn C.
Learning any language afterwards is piss easy because it's practically portable macroassembler and all modern advances in languages were written in C, so you'll know how more complicated stuff was written later on.

Im thinking of making a simple website where you upload pictures and rate them, based on A vs B scenarios.

Should I try ranking them with a binary tree or is there a better ranking method?

I've been programming on and off for a couple of years now, and it's only been in Lisp with a functional style. It's great and I love it, but I want to try a new language. I'm having a lot of trouble trying to decide between C++ and C# though. I want a language that's cross-platform. I want a language with high-level features. I want a language with a lot of ready-to-go libraries available and documented (Scheme-inspired minimalism is great but a huge pressure point when I work on larger projects and have to roll things entirely by hand). I don't want to spend time allocating memory if I don't have to.

I was going to go with C#, but it feels like there's a lot of turmoil going on with .NET/.NET Core/.NET Standard/Mono and all of these frameworks don't seem to inter-operate smoothly. I really don't want to deal with that. Then I was thinking of C++ but I know it as a very clunky language with a lot of manual memory management and I don't want to deal with it. However, it's been around for ages and so has a shit-ton of libraries for a lot of things and is very stable even when standards are updating. However, I've heard that "modern C++" or C++14 and 17 actually reduce the memory and pointer management you need to do by a lot and even have lambdas and so on. One person mentioned that they rarely had to manage memory at all and felt that contemporary C++ was like having a high-performing scripting language. That sounds hyperbolic, but I'm more open to trying it

What should I do, /dpt/?

Got your source loaded up anywhere?

>>60334559
So, basically have a miscellaneous file that gets rc'd in .sbclrc?

I still haven't learned about version control systems.
Plus, it's still far from done.

$ git add .
$ git commit -m "Initial Commit"
$ git remote add origin [url to your repo hub of choice]

Tadaa~

Post the entire function, the setErrCnt method and the getErrCnt method.

Also, is getErrCnt is just an integer or whatever, please explain why it has a getter and setter.
