I'll guess the language that is actually used is better, sweetheart. ;)

wrong

>>62067061
can u translate to brainlet pls

>>62067088
Not an argument, just the automatic gainsaying of what I said.

>>62067101
The translation is: I don't like Python's programming paradigm, so I'll shit on it, even though it's one of the most successful languages that has ever existed.

>>62067061

I used to do Java programming while in highschool. I want to get back into programming now but can't figure out what language I want to learn. Any recommendations for a beginner?

>>62067223
Everything has a proper use case anon, saying that doesn't mean you hate something.

Functionaltards ignore that and seem to preach their favourite paradigm as the only valid one and a silver bullet for all problems, when as a matter of fact it is not. It too must be used sparingly, only when it in fact is the proper tool to tackle the problem at hand.

Hating on a single paradigm is idiotic.

>>62067252
There's VBScript.

>>62067280

>>62067282
I might, but is Java still useful today? I want a language that can actually do stuff.

>>62067265
Just learn a couple, each from different paradigms, but learn them deeply. Don't make the mistake of hopping around languages, just stick with one and master it, but do that for a couple that are different. Something like: Java, Haskell and some scripting language like Ruby.

If you go that route, I can easily recommend two quick tips: Use 'stack' instead of 'cabal' for haskell, and use rbenv for ruby.

for beginners I always recommend a basic text editor like vim, nano, or sublime text and to compile on the command line. intellij community is pretty comfy though if you want a full ide for whatever reason

Just finished few emacs functions that can create new project, compile the current file into shared library, manage linking between files.
Now I just need to create main C program that watches for the lib directory and on file update tries to load/reload the library.
Soon I'll be live coding C.

>>62067369
Technically C. When I was 13 I tried to learn it off a book which told me to write a simple hello world program and then "compile it". I tried everything I could think of to compile it, but MS word, notepad, cmd, etc could not do it. A few years later when I learned java in high school I found out that the book was supposed to come with a cd that had a compiler, but it didn't and the text never mentions it. Fuck that book.

So the first one I really learned was java, and its biggest influence was the opinion that IDEs are for convenience, and should thus offer autocomplete functionality. Though, I really only care about that for object orientated languages. When working with C, assembly, HDLs all I really need is syntax highlighting.

A game lad.
It has many systems for you to learn.

Reposting from the Linux thread, since I might be more likely to find someone who has gone through this:

I've switched my primary system over to GNU/Linux - but 85% of my experience programming has been with .NET C# on a Windows platform.

I understand that .NET Core is out and expanding, but there isn't much there for it (Console applications, web API.)

My other 15% is split between Java, and minimally C++.

Has anyone else made this transition, or have any ideas on how to cope with seemingly handicapping my self? I'd like to continue programming on GNU/Linux its just a bit difficult to kind of 'start over'.

Any recommendations on languages/libraries/frameworks that would make this less painful would be really appreciated (and friendly, if possible - I do understand I am an easy target).

>>62068332
Modern Fortran seems like a nice language. Is in usage anywhere besides NASA?

>>62069461
> I understand that .NET Core is out and expanding, but there isn't much there for it
I TOLD YA
I TOLD YA .NET CORE CAN'T BE VIABLE YET

Ahem.
What kind of programming do you want to perform in Linux?

>>62069461
If you like C#, you might like Vala.
https://en.wikipedia.org/wiki/Vala_(programming_language)

>>62069461
See if MonoDevelop works for you. It is also my understanding that Visual Studio 2010 works in Wine. No luck for Visual Studio 2017 or 2015. Virtual Box might work as well.

>>62067369
HyperCard, but I was only a kid and never learned it properly. I still maintain that it's one of the best damn programming environments ever made. Apple royally fucked up in the 90s by not beating Tim Berners-Lee to making it a web standard.

>>62069508
Vala is practically dead, there's no reason to waste time on it.

>>62069508
Gnome says not to use Vala anymore and it has no active maintainer.

>>62069461
You can transition to cross-platform .NET C# then with http://www.mono-project.com/. For C++ probably, if you aren't already, you will switch into using GCC for compiling instead of whatever Visual Studio had. On another note, since you're using them, how do C# and Java compare?

>>62069494

In regards to "not quite ready" - it certainly is NOT ready for desktop development on _anything_ - including windows. Console applications have limited use, afaik there is no Gaming frameworks hitting it yet (SFML, SDL, Anything - i'd love to be proven wrong).

>What kind of programming do you want to perform in Linux?

I would love to answer this question - maybe some desktop applications (then I need to come up with ideas, of course!)

I was hoping there might be a list of "most wanted" applications or something floating around that people would like to see (much like GNU's priority list, just more scoped - i.e. not "a phone operating system, but open")

This comes back to my lack of ideas, and I understand this *really* impacts any ability for someone to recommend a language to start with.

I think might just be in a rut at this point and need a hobby offline and come back and just explore.

>>62069509

Visual Studio is fantastic application on Windows, and Mono might be a replacement for it. It just feels odd working on what is essentially a non-microsoft backed alternative to Core. (Much respect to the framework its self, i can't imagine the time and effort it would have taken to get that going)

>How do C# and Java compare?

You're going to get a lot of people spitting back and forth about both sides on this one. I am very bias for C#. I started with Java in College (2010) and didn't like it out of the gate. My first job was Java and it just compounded my dislike for it.

C# has had Lambdas for much longer and just "feel" right, lots of short cuts that make code much easier to read, but again, anything I say in Pro for C# can be refuted by anyone that knows Java equally to what I know C#.

public string UserName { get; set; }

will create a Property with a getter and setter very easily. slap private in front of either of them and you have them scoped.

LINQ its self is a whole beast that i won't entirely cover here - I think its very powerful in its own right, maybe comparable to how things "just work" in Python

List<User> users = getUsers(); //whatever, populate the list

// Get all users that havne't confirmed their emails yet

Using some very not well understood laws of the universe, like quantum entanglement, where you can predict the state of two bits no matter how far away they are from each other, you can make predictions about the bits themselves.

For now, if you're OK with targeting Windows only (WinForms/WPF), people should give .NET Framework 4.X a shot, its pretty great (IMO).

If you need something cross platform *AND* its an API/Web - .NET Core is (relatively) ready for that, but not much beyond that,

C64 BASIC
Honestly I was only 7 years old and could not do much more than simple loops and primitive vector graphics

The first language that I learned properly was C on MS-DOS. I had a lot of fun making games, wrote my own keyboard interrupt handler, own timer handler (because the default timer ran at useless 18.2 Hz IIRC), direct blitting to MCGA mode. I still remember the video memory base address, 0xA0000. Generally there wasn't much operating system between you and the hardware. Most games only used DOS for file I/O. Everything else, including keyboard handling, was custom IRQ handlers, bypassing DOS.

Then I was set back for years when Windows 95 came out, I "grew up" and stopped making games for some reason. That was my biggest mistake. I was good at low level coding. I sucked hard at OOP GUI programming.

You can still program playfully today. Limit yourself to a set of tools and limit your scope.

This is my own little engine, there's no momentum, only simple collision logic.
So far everything was fine because I ensured nothing else except the current hero moves (and platforms, both those are static and push everything away) and you can't switch to other hero if:
>you are in air
>you are in platforms path (where platform is or is going to touch in the future)
>you are on platform
And also, you can't switch to a hero that's right below other hero, so it wouldn't be left in air when you move.

I guess I'll just stick with this bug, it's nonintrusive and rare.

True, however there is a GPL'd implementation available now: OpenJFX

I made this for a test. Can someone tell me why won't this compile correctly?

#include <stdio.h>


int main()
{
double tid;
int bake;
bake = 15;
tid = 1.5;
printf("%d", bake * tid);
}

I don't care if I lose decimal, is changing %d to %f the only way?

Writing a naive dynamic memory allocator using free lists for my RTOS

>>62071736
It is. Or explicitly cast the result to int.

once I finish learning general scheme, what implementation should I learn? chicken, guile, and racket (if that's even scheme any more) seem like the major implementations.
so far I think I might go with guile since it was built from the ground up for C FFI, and since I wanna learn C next once I'm done with Scheme I though that might be a good idea
>>62071736
don't know much C, but I think %d is looking for an int, bake * tid evaluates to a double
cast the result and see if it works

I have elements with three pieces of information (3 ints).
Each piece is uniquely identified by 2 of the information pieces.
The third information piece is needed for processing.

I’m thinking i’ll pack the two ints into one and store them in a vector of sets. I’ll have to do bit manipulation each time I process an item (but thats fast?)

Would this be significantly better (performance/readability-wise) than using a pair key and tuple value or (structs even)? It seems like a lot of copying/redundancy with pairs/tuples/structs.

I prefer Ruby over Python because Ruby is much nicer to program in than Python. I don't really like Python as much because it really feels like a hacked together language, a lot of features were added on as an after thought, while Ruby has the feel that it only has a few simple construct which are powerful and everything works much better cohesively. Ruby is also closer to functional programming than Python and has much better OOP (OOP was really an after thought in Python).

what's your alternative? C and rust are quite poor for certain tasks

pro-tip for freshmen csci majors: make a github account, look up how to get a free upgrade for students, and then put all your class programs up in private repositories (for each class). when you finish the class, make the repo public

i don't even know ruby but you're right. it's not elegant at all and there's a lot of stuff that feels ad-hoc. i'm too busy to learn a language for fun now but i plan on learning ruby when i have the time

python only accidentally got popular, while ruby got accidentally tethered to rails shit. Literally there are quite a few people who even go into rails without thinking they should even learn ruby. It's a fucking disgusting culture. So, people don't like to think, and they go "oh yeah, python is in college, ruby is for rails".

You should go with Ruby for your purpose, it's a much better language that has more to offer than rails. Check the ruby koans, and use pry, and use rbenv.

I took a numerical optimization class and we used Fortran in it. I wouldn't say I'm an expert, but honestly it wasn't that bad. It's not like you're building a huge application, those super numerical problems are naturally very procedural anyway.

It's a useless language, and forces people learning it as their first to have to un-learn in and re-learn proper programming when they finally move on to better things.

Learn Ruby to switch over to Crystal. The Crystal team plans on having 1.0 released around 2018, and with the maturity of the language, and the power it posses, expect a very nice following to occur. Besides, Crystal is like the fluff of Ruby, with the speed of any compiled language, it's a way better alternative to python imo-to

>>62072500
Never touched Haskell, but if C is faster than Haskell, then Crystal should be faster. It's about as fast as C++, from my testing. The people claim a design goal is to be fast as C, though, so maybe 1.0 will increase speed? Think about it like this, you could write an OS in Crystal if you wanted to, and it wouldn't go any slower than a C++ OS.

One downside to Crystal is the fact that it isn't supported on Windows yet, but i dont use Windows so i dont really care.

Is it statically or dynamically typechecked?

I have an moral opposition to dynamically typechecked languages.

>>62066877

Why do languages like C# and Java to part input of numerical types. Both take strings fine, but you have to convert numerical input. C/C++ handles things fine.

>>62072652
For certain applications C++ can beat C, but it's hardly idiomatic

>>62072718
Why do they have to parse it? C still has to use atoi and other functions, not sure what you mean. Every language has to do that, it's just syntax.

It weakly-typed, so you can do either or.

some instances, like the

initialize

function needed to declare new classes, or declaring blank arrays, require you to statically type, but in most cases, doing

 var = 2 

or

 var = Int32 

or

 var = 2i32 

all work as you would expect

Which programming language requires the greatest volume of intelligence to become an expert in?

business idea: a language with strong dynamic typing

>>62072740

Hmm, maybe I'm getting it wrong then. For example:

C++

int number = 2;
cin >> number;
cout << number;

Whereas in Java:

Scanner reader = new Scanner(System.in);

int number = Integer.parseInt(reader.nextLine());

System.out.println(number);

Forget creating a scanner and all that, why do I need to specifically parse an int. I guess in a way it's the same, but looks verbose?

>>62072856
I think every language is similar in intelligence required, but the amount of effort and how well that scales with intelligence does vary.

>>62072867
C doesn't have that, you said C/C++. Pedantry aside, it's just implicitly doing the same thing as Java.

>>62072867
C++ is still parsing it. you're not passing it in the number 2, you're passing in the character "2", which is 0x32, which then has to be parsed into the number you want. you should learn C because you seem to think programs are magic, which is a really bad sign unless you're brand new

I don't think they're magic. And I started with C++ several months ago, but in class we use Java. I just noticed this difference. And was curious about the "why" behind the decision for the syntax to be like that. I think some of the resources online have taught me how but not why and I'm just as interested in why as I am the how. Thanks for the help.
