/dpt/ - Daily Programming Thread

>>58123966
This thread is pathetic. It is not about programming. It's just a bunch of computers illiterates and first semesters memeing about whatever they just learned.

A quick search shows that most arguments used here are not original and have been copied from some trendy tech blog or other shit site.

The only real programming questions I have seen so far are from beginners(it's fine to be a beginner btw).

This entire site is shit and I don't know why anyone would regularly come here.

It is not. Is really easy to come up with original arguments if you know something about the subject. In this case, programming languages and their applications.

The link you posted is the fist google result for "golang trash". Is a short article with poor argumentation(I had already seen it and I'm a golang programmer). One might think you just searched for "golang trash" and posted the first link for the solely for the purpose of trolling.

Nothing specific, I was going to install the android sdk and try to get into some make some applets but I keep putting it off. Atm I don't have an isp so I'd have to go out and download it from like the library or some other wifi hotspot something.

It's stressful since I know that it's not hard to get a job as a dev and all I have to do is just cobble some portfolio together but at the same time I can't ever think of what to make and that all that's holding me back is me.

I dropped out due to bad grades (I'm not stupid, honestly I got an A on my programming final and did well in the CS classes) so I'm just in this awkward transitory period. And I'm just trying to sort my life out but there's a lot i need to get in order. Programming to me is just something I know I have to pursue since it pays fairly well (more than what I'm used to) and it's not that difficult. So I've completely removed myself from the hobby aspect of it.

In my experience:

The best way to get around with a new technology, sdk, language, framework, etc, is not with the tutorials. Is actually implementing something you are about. You learn what you need on the way.

>it's the first google result
So? Of course that's what I'l find when I'm facing concerns of that specific nature (golang's attempt at ASM).

My point was more that the arguments (as you would see if you've read it) are similar. The problems are the same. Practically nobody in programming phrase their problems in specific circumstance like you might with social issues or whatever. You have a issues in general.

That's why they bother you I think. They don't have drastically different steps in the inference because we're dealing with such solid subjects and we're on the whole not retarded.

It's not bad that peopel come with the same complaints. It's very good that when people complain about OOP they end up complaining about the same things largely. If we didn't have that we would either have far too many issues with OOP, so many that people have trouble categorizing their importance, or we would have problems that are of a subjective nature.

What we should ask ourselves is why people don't solve the issues more.
Why is the primary performance oriented language (C++) also object oriented and has a culture that promotes it? Why don't we have better abstractions for the space that C++ covers? (arguably C++14 and up is working on that but before then it was pretty barren)

Solving issues shouldn't be this hard.

I get that the language is much more elegant than, say, Java, but what's the point in learning it if no one actually uses it to code anything (expect for meme projects like xmonad)? What's the point in investing your limited free time time to learn a new language when you can't do anything useful with it?

It's hipsterware.
I'd love to see distributed web become a reality just like you, but IPFS is not the solution in my opinion. It tries to be a better bittorrent, but fails in doing so. All the problems IPFS faces have already been solved in the bittorrent protocol. They were better off writing a convenience layer on top of bittorrent.

Yeah, they are just shitting out of their mouths. Not phrasing well thought problems in relation to a well defined scenario.

>Practically nobody in programming phrase their problems in specific circumstance like you might with social issues or whatever
They have almost any steps in the inference. They just throw they biased opinion in a blog post.

>and we're on the whole not retarded.
Yes, "we" are.

>with such solid subjects and we're on the whole not retarded.
The problem is not agreeing with other person.
The problem is that the complains are usually not well pondered memes.

>What we should ask ourselves is why people don't solve the issues more.
They do btw. But people that solve issues are mostly in academia, trying to solve issues, not sell shit. And people that I complained about are complete imbeciles working in industry buying shit products("the next big thing") from some shit company that have more lawyers than engineers.

You can interpret it in the way that every class should only have one method.

>>58125326
> In Go I would just use a channel but it doesn't seem as straightforward looking at some Rust docs.

Rust has channels too. And they are not hard to use:

    let (tx, rx) = std::sync::mpsc::channel();
    // and then in each thread thread
    let thread_local = tx.clone();
    // do work
    tx.send(value);

But your real problem is the main thread exits and it kills all the child threads before they are finished.

>>58125436
That works great, thanks.

>>58125564
errr, that should be thread_local.send(value). I'd personally just call it tx, too, though.

>>58125530
>You can interpret it in the way that every class should only have one method.
You don't understand nigga. You want to keep your code as modular as possible. The SOLID (https://en.wikipedia.org/wiki/SOLID_(object-oriented_design)) helps you with that. This way you can easily modify the behavior of the code without refactoring the entire codebase.

>>58125983

All languages are shit. Find one you like and use it.

Just make sure to call it shit when anyone asks you about it so that way you're covering for any sort of potential intellectual weakness you'd otherwise show by actually liking a given technology.

Other programming languages, if you're looking for a serious answer. The first languages after a steady hand and some magnets were opcodes to a CPU, which basically 0 and 1s. Even then nobody really did that for any length of time, it's unusuable. Assembly makes those calls into somewhat readable English. Then people used that to build more compilers that compile their own code straight into binaries. So they're "bootstrapped". Now days a lot of people write new languages in C.

The point is to become a better programmer.

If you learn C and C++ and Java and C#, you learned languages that are pretty close together.

If you learned C and Scheme and Perl and Haskell, you have languages with very different approaches, forcing you to do things differently. Even if you won't use all of them in your daily production, it's still worth learning them because it will make a better overall programmer.

LEARN the terms. There is a difference between memorizing keywords in certain places and actually learning them, what they do, why they'd be used and why they're called what they are. Work with the language, use those terms one by one on your own, and then all the boilerplate and necessities get filtered out and you only have to concentrate on how the logic and structure of the program works.

>>58126404

Because you want to learn different paradigms. What would be the point of understanding both java and c++ to a similar level? If anything if you know one you can learn the other in a couple of days.

>What would be the point of understanding both java and c++ to a similar level? If anything if you know one you can learn the other in a couple of days
That's far more true of languages like C# and Java. C++ is much lower level than Java, doesn't have GC as Java does, has entirely different syntax for many things, has a giant stdlib, different build and linking structure, the standard library has its own reference pointer types with shared and unique ptrs, you'll need to learn memory allocation, better type safety, templates, etc.

Nobody who only knows Java and languages as high level as Java with the same type of GC and other concepts is going to pick up and start writing acceptable C++ code in a matter of days.

This is wrong.

I've met a lot of physicists and math guys (having studied math for 2 years myself) and 95% of them can't program for shit.


Like RMS said: "programming is a craftsmanship ship, not a science." It's a lot about best practices and a hell lot about experience. You can't give a formula for a well-designed program. And just looking through the documentation or doing an intro tutorial doesn't cut it at all.

now

cmp #0x615a, 0x0(r15)

Now in 0x0 r15 is 1byte stored (two hex values), how is it possible to compare 2 bytes?

What do you guys think will more likely take off: augmented reality or virtual reality?

>>58127774

Fact: GCC is trash

>>58127692
I thought that too, but the book i'm reading hasn't covered operator overloading yet.
Only constructors with an istream& param.

>>58127701
AFAIK there's a prefix / modifier that can be applied to the instruction which specifies what kind of value is at the memory address (byte, word, dword, etc.). Most, if not all, assemblers will automatically apply the correct prefix based on what register or immediate (constant) you are comparing it to.

GCC is OK, but I find clang to be faster to compile with on-par performance.

>>58127774

It appears your textbook is being shitty and using material that's covered later.

>>58127811
i agree. augmented reality seems more reasonable and applicable in the real world.

I feel like augmented reality is genuinely where the software industry is headed.

so i'm wondering what devices will resonate best with this technology and what languages will also be most beneficial. thinking c++ since its more resourceful than java.

>>58127841
I will say though, VR seems like it could have some really cool applications outside of what it's commonly been used for (video games). Maybe still media, galleries, movies, or job applications like training simulators for pilots or quarry truck drivers. But for muh gaymes, it's really silly, because you get a massive lack of peripherals (two hands and a camera as your eyes), so it limits what the game can achieve in complexity, but you also get a massively limited immersion (rock climbing, but with your feet still on the carpet in your socks, you just get vertigo when you look down)

>>58127894
i feel like the best device might be the car especially when they become completely self driving and electric.

imagine being able to be on the road driving anywhere for virtually no cost and without the exhaustion of having to drive. at that point people can probably live in their cars comfortably.

I mean if you're okay with the issues that come with making it all dynamic and not static then it's decent, I guess. Haskell can also do it the more dynamic way.

In Haskell + some extensions or something with a similar type system you can do:

data Lists :: [*] -> * where
    LNil :: Lists '[]
    LCons :: [a] -> Lists as -> Lists (a : as)

data Tuple :: [*] -> * where
    TNil :: Tuple '[]
    TCons :: a -> Tuple as -> Tuple (a : as)

zipH :: Lists as -> [Tuple as]
zipH LNil = []
zipH (LCons xs LNil) = TCons <$> xs <*> pure TNil
zipH (LCons xs ls) = zipWith TCons xs $ zipH ls

>>58128736

Breakout is a good one, and fairly simple, too.

>>58128911
Example usage:

zipH (LCons [1, 2, 3] (LCons ['a', 'b', 'c', 'd'] LNil)) = [TCons 1 (TCons 'a' TNil), TCons 2 (TCons 'b' TNil), TCons 3 (TCons 'c' TNil)]

why is this a good system?

They would pattern match using that syntax, yes.

You could do it with operators instead to make it a bit nicer if you wanted.

>>58129245
Explain the scenario this has actually happened to you, or are you mistaking the arch Linux irc for a job?

>>58129198
is it time-critical?

>>58129269
i've filed tickets in JIRA for exactly that, waited a few days for the result too

>>58129273
Not particularly but I'm writing it on my own to make it faster in the first place since it takes 10 minutes ATM.

what I normally do in such cases when I have to solve an esoteric problem is to retreat to my comfy thinking chair and ponder the problem for as long as it takes.

Again, scenario? I can't imagine any place with more than 5 employees copy and pasting a command into a production server.

So do we post in the less gay thread or the one that was posted first?

>>58129425
You know the rules. It's not gay if you're following the rules

>>58129425
I'm posting in the (slightly) less gay one, recommend you do the same.

Less gay thread has more posts. Moving there.
