what do you mean by this? This is programming thread anyway.
Or you are refering to video games? I stopped playing them while I was still with Windows but I see that many other ways are there to play games on gnu+linux,also the biggest video games platform,Steam,started to natively support gnu+linux, and that has to mean something.
I am reading gopl and I don't particularly understand one paragraph in 6.2.
"If all the methods of a named type T have a receiver type of T itself (not *T), it is safe to copy instances of that type; calling any of its methods necessarily makes a copy. [...] But if any method has a pointer receiver, you should avoid copying instances of T because doing so may violate internal invariants. [...] Subsequent method calls would have unpredictable effects."
Why would this result in internal invariants?
I don't see how this is related to pointer method receivers.
I can see that if you copy a type which has a pointer member that you might cause internal invariants because both values reference the same underlying member, but I don't see how that means that each type which only has method receivers of type T and not of type *T is safe from this.

List is backed by an array, if you are worried about memory usage then change the Capacity property.

wait so, in C, because the types are verified as correct by the compiler at compile time, there's no type information in the assembly, therefore it doesn't need to check shit at runtime, so it's faster than dynamic languages?

>>52238646
>because the types are verified as correct by the compiler at compile time
C's type system is static/weak and allows all kinds of explicit or implicit casting, the former of which is idiomatic C and mostly obviates the benefits of static typing. The verification it does is rudimentary. If you want a performant language that actually attempts to nix type errors you can use Rust or all kinds of C dialects engineered for that purpose, or more practially, C++.
The rest is all correct though.
>>52238709
ok.. try adding a struct to an int. what happens?
>>52238714
Sounds like you've never used a strongly-OOPed language.
In most 'true' OOP languages (ie languages that are OOP from the start, not just 'with oop elements') types are objects that have properties and whatnot. In non-OOP languages like C this isn't the case
>>52238714
I'd say that's not strictly true, because a large part of OOP is introducing new types (through classes) and subtyping relations and things like that.
But yes, C having weak typing has nothing to do with C not being OOP.

Do any of you guys use an alternative implementation of malloc?
Seems like it would be an easy win of performance, especially on Windows
Most stuff I find don't seem to have been updated in the last 10 years, though I guess that malloc is malloc. It's just that I was looking for something that would scale with modern architectures, with thread-local caches for small allocations and shit
>>52238755
>In non-OOP languages like C this isn't the case
That has nothing to do with C not being OOP. C is weakly typed by design.
>>52238756
I didn't say OOP has nothing to do with types. I said types have nothing to do with OOP.
You can have types without anything resembling OOP.
>>52238833
>alternative implementation of malloc
You mean a custom memory manager? Ultimately you have to call malloc to get memory, the only difference is how often it gets called.
>>52238698
That comment.
>>52238833
Why tho?
If you're in a situation where malloc would cause performance issues, you're probably working on an embedded system, the general rule in embedded programming is no dynamic memory allocation for any reason.
It leads to too many things that can go wrong, especially on embedded chips that require years of uptime or life critical shit.
what's a language that is:
- strongly, statically typed
- type inference
- OOP from the ground up (i want to do cool shit like "asdf".length() )
- compiled ofc
Please rate my implementation of grep / filter
I wrote it in C++ because I anticipated pointer usage, however turns out I didn't need to use pointers at all, so this code could be changed to any language without much trouble.
Whole program, with more detailed comments, is on my website:
http://joeburger.ax.lt/cpp/fastFilter.txt
Here's the filter function:/*
* Precondition:
* - size is the number of elements in the array
* Postcondition:
* - size is the number of elements in the array which
* satisfy the callback function
* - array is sorted such that all elements which
* satisfy the callback function precede those that don't
*/
template <class T>
void filter(T * array, int & size,
std::function<bool(int)> callback) {
for (unsigned element = 0; element < size;)
if (!callback(array[element]))
std::swap(array[element], array[--size]);
else
element++;
}
You can download it @ http://joeburger.ax.lt/cpp/fastFilter.cpp
and run it withg++ -std=c++11 -fpermissive fastFilter.cpp

Missing the point. Malloc causes a program to switch between user mode and kernel mode. A lot of consecutive calls to malloc will call performance issues on almost any platform.
>>52238888
What's wrong with length("asfd")?
It's less typing
Though I guess you don't get the neat auto-completion
>>52238833
Hoard is pretty popular, although it's GPL and somewhat expensive if you want to use it in a proprietary application.
>>52238931
Typically, video games (if performance is that important) just don't call malloc() on the fly at all. They allocate everything up front and use "custom allocators" to fit the specific use cases, like pools, stacks, heaps, etc.
>>52238954
The engine is open source, though the game built on top of it probably won't be

Just wait for JAI.
As far as I understand it, because in Haskell there are no side effects, in Haskell you can just compile with -threaded or something and you get free multithreading.
But what are the advantages of imperative? Is it just shit?
>>52239029
much faster, much easier to learn, much less complex.
>>52238979
You'd have to GPL the engine, but depending on how the game itself is specified you can get away with keeping it all proprietary. For example, if all the game code is in a scripting language, that counts as data and is not "infected" by the GPL.
>>52239003
It's pretty unlikely, if you separate the "engine code" and "game code" enough, that the quick and dirty "game code" will even need to do any allocation of its own.
>>52239029
It's supposedly easier, but I don't buy it. I think that's a nurture vs. nature issue.
In C, which is better for performance? passing a boolean to a function as an int or as a char?
I'm writing a VM so it's important.
>>52239058
char is 1 byte
>>52239058
There are no boolean in C. But the fastest would be to pass it using word sized value, ie int.
>>52239065
Yes, but parameters are passed on the stack, and the stack is word aligned.
>>52239071
>There are no boolean in C
You think i didn't know that?
I obviously meant a parameter that is only interpreted as true or false.

>>52239050
I disagree that it's somehow inherently faster. There's nothing about functional programming that REQUIRES garbage collection or tons of laziness or anything else that makes existing functional languages slower.
You can have a functional language with pointers, malloc(), and free() just fine. And the advantage that a functional language has over an imperative language is that the type system can be far more expressive and it's possible to mostly automate static verification.

If you link to a GPL library your code must also be GPL. LGPL does not have this restriction.

i don't think it's the garbage collection that is making it slow really

C is good, but it can't compile to PDF, so it's not really that useful.
>>52239175
Moreover, it's often not clear if two programs which supposedly have the same functionality really do the same thing. Different languages sometimes require very different ways of expressing the same intent. Certain types of bug are rare in typical Haskell programs that are more common in other languages and vice versa, due to strong typing, automatic memory management and lazy evaluation.
Nonetheless, it is usually possible to write a Haskell program that performs as well as, or better than, the same program written in any other language. The main caveat is that you may have to modify your code significantly in order to improve its performance. Compilers such as GHC are good at eliminating layers of abstraction, but they aren't perfect, and often need some help.
There are many non-invasive techniques: compiler options, for example. Then there are techniques that require adding some small amounts of performance cruft to your program: strictness annotations, for example. If you still don't get the best performance, though, it might be necessary to resort to larger refactorings.

>I disagree that it's somehow inherently faster.
If not inherently, then certainly practically.
>There's nothing about functional programming that REQUIRES garbage collection
Yes there is, unless you use an insane amount of memory. You basically need GC to be able to avoid mutation in any meaningful way.
>You can have a functional language with pointers, malloc(), and free() just fine.
Not pure. If you want to mix imperative and functional there's plenty of languages for that.
Why are C parameters passed on the fucking stack?
Why not pass them by register? if you have more parameters than registers then you can just pass the rest of them on the stack.

Static or dynamic, your code must also be GPL.

I just started a new job (first job with salary over 6 figures). I have a laptop and 2 other monitors: One is 19 inch and the other is 17, I think?
I use dual 27s at home. Even though my setup is technically 3 monitors it feels bitchmade because I'm used to a lot of screenspace.
Ugh.......
Working on a parametric equation graphing utility in Java. Here some neat code.private void draw()

Point2D p = curveFunction();
g.setStroke(Color.RED);
double newX = 400 + p.getX();
double newY = 300 + p.getY();
if(oldx != 400 && oldy !=300)
g.strokeLine(oldx, oldy, newX, newY);
//g.strokeOval(newX, newY, 1, 1);
oldx = newX;
oldy = newY;
}
private Point2D curveFunction()
{
double x = 4 * sin(t) * (pow(E, cos(t)) - 2 * cos(4*t) - pow(sin(t/12), 5));
double y = cos(t) * (pow(E, cos(t)) - 2 * cos(4*t) - pow(sin(t/12), 5));
return new Point2D(x,-y).multiply(50);

That has nothing at all to do with functional programming. Haskell's type system can't even verify the monad laws. Most "functional" (actually self-hating imperative) languages are even worse.

>You basically need GC to be able to avoid mutation in any meaningful way.
1. That's not true. See the Clean language, and linear types in general.
2. Avoiding mutation is not necessary, as long as it's quantified.
>Not pure.
Here we go again. It's okay to do anything that can be seen as a "side effect"; the types just have to be modeled such that the program will be correct under any evaluation strategy. That is the core principle of purity, and why it permits so many optimizations.
>>52239225
Then don't make generalizations like "functional is slower than imperative".
>>52239321
Haskell is just one functional language. I don't think Haskell is particularly safe at all, from a verification standpoint.
>>52239128
In particular, linear types such as in ATS completely eliminate the need for garbage collection without impacting the functional-ity of the language; while also ensuring there is no memory-related error in a compiled program.
>>52239175
Usually it's the write barrier or bad allocation strategies which are caused by bad code; othertimes it's because the wrong parameters were given to the GC (such as having a very small minor heap for a program that generates large ephemeral objects). Another possible issue is compaction: if you fragment the GC-managed memory areas too much, a compaction pass must be applied; thus doing many weirdly-sized allocations can impact performance a lot. Those are all e.g. bad gc parameters rather than the gc itself being an issue.
There's also many GC implementations, ranging widely in terms of speed and latency. There are even so-called realtime garbage collectors.
That said, compiling is not an easy task, and most likely the largest chunk of reduce performance wrt non-C languages comes from lacking optimizations in the compiler, especially full-program and link-time optimizers, as a lot of them want to support a rapid development cycle using a REPL. Specialized compilers like mlton and the ocaml flambda branch try to address that, but needless to say, that shit isn't easy to develop.
Notice that even java and its mediocre GC perform quite well, and that ATS is an example of a functional programming language that is blazing fast (despite very little development effort going into it).
>>52239301
PDFs are, by definition, more portable than binary executable. It's only natural that a so-called 'portable' language such as C should compile to it.

Multi-monitor setups are complete shit unless they are all the same model.
The colours never fucking match up no matter what you tweak, unless they have exactly the same configuration.
and even if you do get one or two background colours to match, the rest wont.

Purity means no side-effects. The following function is not pure:let fn () =
let x = ref 0 in
for i = 0 to 10 do
x := i + !x
done;
Printf.printf "%d%!" x
And neither is the following:let fn j =
let x = ref 0 in
for i = j to 10 do
x := i + !x
done;
!x

>>52239382
LLVM is designed so you have to go out of your way to even implement mutation (by putting allocas everywhere), but that doesn't make LLVM actually fast. One needs to design many complex transformation passes that do not come with LLVM to get anywhere near the ballpark; and non-shit compilers like GCC go a hell of a lot further with C, with complex static analysis, statistical analysis, code pre and post transformation, etc.
LLVM gives you theoretical portability and that's it.
