Haskell was the rust before Rust.
Its overhyped because it was different, but is shit.
The language is fragmented, no dependent types, hole-oriented programming which is a bad habit. Not that holes are bad. And then if you want a rabbit-hole go read up on the Xtension issue.

>>61282407
I don't think you understand what is happening here.

Anyway, I think haskell should just stop with extending the language.
There is way too much in it to the point where it becomes the C++ of functional languages.
All just because some dudes want to add their personal academic research to the compiler.

>>61282397
idris is pretty cool and nice, but I don't know how practical it will be anytime soon.

>>61282552
>its unnecessary
I don't understand what you mean. How can making faster code more comfortable to write be unnecessary?
From the features I have seen, like SOA and memory alignment, it is really well thought out.
>t won't be worth using simp...
Its not really complicated, so I don't know what you would need to learn in order to use it, except for some simplified syntax for things that you are doing anyway already if you wish for "performant" code.
If you understand the principle concepts of C, learning jai will not be difficult, but writing code will be much more comfortable.
And if the compiler doesn't spit out horrible error messages like C++ there will be a real benefit of using it.

>>>61282563
>Literally cant have an opinion until he either releases an RC or 1.0 itself.
With this I can kind of agree.
It seems kind of mature from his demos though.
>I dont see what the appeal of it so far though.
Well the appeal is that C++ sucks, but you still want higher level constructs and ease of programming then C.
If it can achieve this, I can imagine this language skyrocketing.
When Jai releases, I will work on libraries, even if it is a doomed toy language or not, since I am convinced that the principles it employs are good.

>>61282675

I somehow agree, but I still think that its pretty elegant from a conceptual point of view.
Sure you can learn idris or some other better functional language instead, except you won't learn as much, as there are no large codebases and libraries to learn from.

>and you sound like one of the sort of mouthbreathers here who makes summary judgements on programming languages' elegance based on syntax.

This I totally understand,
but as is portrayed by simon peyton jones in this wonderful video https://www.youtube.com/watch?v=iSmkqocn0oQ , haskell wishes to be useful.
I don't think they are heading the right way with adding more and more to the language, at least when it comes to usefulness.
You won't get around to learning these extension when it comes to understanding common libraries nowadays, and I just kind of don't want to.
Not because I am tired of learning, but I'd rather use a language that was a bit smarter from the get-go (idris for example, although it is useless).

>range returns from slice and arrays
How do you mean? You can return a range of an array or slice via [x:y].
>generics(interface{} is a poor substitute)
The better substitute is defined interfaces combined with `go generate` instead of an empty catchall.

>case sensitive scoping
I like this one since you know the access of something immediately by its name alone.

>>61283573
>Dont forget Go's forced formatting.
This is great, having a standard format makes it easy to parse since you know what to expect, you can render it however your want in your editor and just fmt to standard on save, this feels like the whole space vs tabs thing, someone can just render tabs to the indent size they want which is why it's preferable, with go standard format it's the same argument, since it's expected to be that way you can just parse it and render it how you wish to see it but that won't impact other people, which is great because everyone gets what they want that way.

That's intentionally obfuscated C code. Practical C code which uses typedefs for abstraction or readability looks nothing like that.

>Most programmers are ...
Parsers usually aren't human, the goal is not to make something ismpler for humans it's to make something simpler for machines to parse and then in turn something easier for you specifically to work with as you just parse, render, and format.

In C people do this already with tools like clang-format, they take whatever, parse it, format it to their preferred format, then format it back when saving/publishing to a project standard, having this standard be global I think is beneficial for everyone involved instead of hoping projects adopt one or having to write your own lexer and handle every crazy exception that is compiler legal but odd.

Nobody is forcing you or anyone else to use GPL code as the base of your code. Write from scratch instead of complaining that you can't just take shit.

Are you confused? I'm boasting about how easy it is to take your shit and profit off of it, I'm entitled to by the license. I'm saying the authors are stupid, it's unfortunate for them to put in work with no reward.

template filter(alias predicate)
if (is(typeof(unaryFun!predicate)))
{
    auto filter(Range)(Range range) if (isInputRange!(Unqual!Range))
    {
        return FilterResult!(unaryFun!predicate, Range)(range);
    }
}

pretty nice, isn't it?

>>61284179
Actually, GPL is pretty alright for forcing the users to keep the source open.

One of the things I worry about is the IoT garbage that's gaining popularity. It's important that GPL'd Linux gains more traction than *BSD ones.

With BSD licenses, companies like Microsoft can basically steal their code close their source. So they can ride on BSD software to create IoT spying drones. With GPL you can identify where the botnet lies.

That doesn't mean illegalizing murder is meaningless because you can sometimes get away with it.

It depends, like how do you know your router is running linux? You can look at its behavior, what services it runs, likely identify a package and the corresponding OS that way (like the admin interface to my router includes the OS in the server header

You can hide this of course, but if you don't take sufficient precaution to and it's discovered you're in violation of the GPL with a product you've already shipped you can get fucked hard, it's assumed businesses wouldn't want to take this risk.

Big projects are hard to reverse engineer. However there is already a case where GPL violators got sued for what they did.

However, if you are talking about license, it simple does not permit you to close it off legally. You are basically saying "it's not a murder if no one sees me doing it". People still kill others and tend to get away with it. This is not law's fault.

I'm dead serious, what are you even talking about? How is explaining the GPL to someone grasping at straws? It's not even an argument, it's a statment. I'm not even arguing to begin with, I'm asking a question and nobody can answer it because I guess nobody speaks English. Tell me honestly, what do you think I'm asking, arguing, or saying? I really want to know how you interpreted these posts, because they're pretty clear.

>>61284787
That doesn't explain anything. You're saying that someone is doing something, you listed out that 1 is someone stealing source code and 2 is someone making a legal exception to theft because the law is now ineffective. What do these things even have in common and who are they directed at, why? What's the relevance to the question of "how does someone get caught stealing?"

>>61284799

GPL user agreement.

>>61284821

BSD license permits user to close of the source and GPL does not.

>>61284799
>I asked how someone would detect GPL'd software on a hardware SoC, how does that answer tthe question when they're talking about Linux? Do you honestly think Linux is the only GPL'd piece of software?
No, but that's the general strategy: look at the behavior of the software, this can often give away what software it is or libraries it's using. Most software of sufficient complexity has idiosyncratic behaviors.

>>61284822
>GPL user agreement.
Okay but why are you talking about it? What does it have to do with my posts, did you misquote?

>Are you literally projecting your anger in the reply box?
How are you confusing confusion for anger? Why assert that just because someone is inquiring for more information that they're angry? I would say I've been more than patient, I'm slightly annoyed at the incompetence but I'm not even expressing that. Have I been anything other than patient with these people?

>>61284844
What does that have to do with the question?

>What's making you so upset that you are randomly throwing in words that has absolutely 0 meaning?
You'll have to explain to me what you mean, I'm not sure what specifically you're taking for "upset", have you ever used text communication before? It's very neutral on purpose because it has to be, you don't have as uch control on things like emphasis or inflection with plain text.

I just asked a question, usually when people do that they want an answer. Instead I got a bunch of posts of people not understanding the question and replying with actual inane comments.

>>61284927
If someone takes a GPL'd project and uses it in a hardware project, how would they get caught? Especially if it's obfuscated, it seems difficult to begin with (reverse engineering closed source hardware).

I think it's a simple question but for some reason people brought up murder, food, the BSD license, emotions, and GPL clauses. One guy made a serious response about detecting Linux, but I'm asking generally, I don't think someone shipping ap roduct wouldn't try to obfuscate things, so while it may be easy for a 1:1 copy, what about a modified version of some project?

That's basically the summery.

>>61284948

Your fellow project members can legally sue you. Otherwise decompilation (in theory). Note that paraphrasing method names won't save you if you actually get caught.

Reminder that even the autistic AGPLv3 recognizes exceptions to its "can't lock down hardware" autism, precisely in critical equipment where that's to be expected, such as medical hardware. Sometimes I doubt you people even read the license text.

Licenses are never a problem until someone sues you. It's highly unlikely that's gonna happen unless you're an actual corporation with actual money and assets to target.

Also, try suing the Chinese motherfucker.

This is the question, how do you even extract binaries like that? Especially if the architecture is something exotic or custom. The question is "how" do they get caught, what is the process. Nobody is explaining that.

Lisp isn't that innovative anymore. It represented a huge improvement over shit languages like ALGOL, COBOL, Fortran, staples of the time. Modern languages are full of good Lisp features. It's not that huge mindfuck anymore.

The only thing still truly unique to Lisp is it's metaprogramming. Macros are common but even that is a completely shit feature. The real feature is FEXPs, which essentially let you add custom clauses to lisp's EVAL. They were replaced by structural "macros" because they didn't play well with dynamic scoping at the time and other such things that are non-issues today. It's sad that most major Lisps still have macros and not FEXPs when the latter is clearly superior.

Yes, the majority of professional programmers are salaried and not project based. Contractors, being the next most common sort of programmer, do work project to project but are usually associated with a firm who will have jobs lined up for them. Often a contracting firm will guarantee a programmer's salary for as long as they're with the firm, even if they don't have work for them at some point.

Programmers are generally paid pretty well, you can look up ranges, if you're hired in a rural area you'll make less but it's still quite livable. Generally the biggest hurdle people face in getting into the field is training.

Rotation of vector is typically described in a matrix. You can encode rotation in a vector type because it has three components, but it's not really a spatial vector in the way points or directions are.

>A vector can represent a direction and a rotation, and I wish to rotate a direction.
A vector can represent a point or a direction but not really rotation. The components of spatial vectors are distance, you'd measure them in things like feet or meters, but rotation is measured in degrees or radians, which aren't distances. Like it makes no sense to say "I'll rotate this vector by 3 feet to the left".

>But why would a matrix be needed?
Typically you achieve a rotated vector by multiplying it by a transformation matrix, like that's the interface most systems provide. The reason they do that is because you can represent a lot of transformations as a matrix, and matrices have some nice properties around composing transformations.

Because you can create a transformation matrix where the dot product of it and a vector is that vector rotated by some number of degrees in some plane.

Put C# into unsafe mode and it's basically ghetto C.

If I have memory that's to be shared between threads but the time scale at which they would have to be shared is seconds to minutes can I just ignore memory barriers? I have a multiple producer single consumer system but the producers work well ahead of the consumer and are completely separate from each other.

I just don't know when memory gets synced normally. I'm assuming seconds is a large enough time scale for it to be guaranteed but I don't know at all.

In the case of C#, it's turned into data that instructs the VM to do something, it's not machine code that can be natively interpreted.

Anyone knows a good way to fix the error in pic related?
Both Paths.resolve() and
FileSystem.getDefault.getPath()

Throws that error on some of the Chinese cartoons it's trying to create symlinks for when special characters appear in the Path.

Solved the program from crashing with try catch, but would like to have a better solutions for getting the path.

Try

javac -encoding UTF8 Main.java

or whatever you do to start it.

REEEEEEEEEEEEEEEEEEEE I found a new one

Is '>' a protected symbol or something for console commands?
I tried using "->" as an indicator that the next name will be the filename that is used for saving but I'm getting errors

Ahhhh right thanks

Scheme is the easiest to learn and the most consistent. Lisp has far too much cruft.

When to use size_t?

>>61286486
When describing the size of an object or an array index.
It's actually you would use quite a lot.

>>61286495
It's not clear to me when/why I would use it rather than an unsigned int.

>>61286518
size_t is set as a typedef of the maximum possible size an object could be. It's just more portable to use it.
If you were using unsigned, you can't representing something more than 4GB on x86-64 computers.

New thread.

>>61286546
Is it illegal to write a struct or array whose size cannot be contained in a size_t?

>>61285781
I'm not sure what you are asking exactly, but you need to synchronize that shit. The shared memory is critical section. Semaphores, mutexes, condition variables, pick and synchronize it.

>>61286636
size_t is large enough so it's not possible for such a struct/array to exist.
size_t is typically the same as the word size of the CPU. That is 32-bits on a 32-bit system and 64-bits on a 64-bit system.
You cannot have an array/struct larger than size_t, because it literally would not fit into memory.

solve a convex program in bash. its easy in python, show me the bash solution.

lo and behold, we uncover what python is for. not growing lists but providing a high level language that calls subroutines implemented in C
