Is that Winry Rockbell?

Anyways,
Generally, garbage collection is pretty straightforward if you do one or the other of the following:

(1) Have purely sequential code with generational/incremental GC or reference counting (naive or deferred). That is something that's very well understood and generalizable to multiple threads as long as you have thread-local heaps (so that each threads operates sequentially as far as memory management is concerned).

(2) Have concurrent code with a stop-the-world garbage collector. You can these days basically just link the Boehm GC and have a pretty good baseline for that approach. The downside is, of course, that GC pauses for multi-GB heaps can run to several seconds.

does anyone know of a good online crash-course or guide to start learning this shit?

i dont think i will be making a polished app anytime soon but im hoping can atleast make a crude semi functional concept app to try and get an investor or partner up with people who can make this app happen.

Wrong.
C is not any better at kernel development than C++ is.

C++ adds plenty of things useful in any context, including kernels, without adding any overhead that wouldn't be there in C.

powershell noob, using v5.1 and only coding for 5+

I am doing some scripting for automatic scheduled backing up of shit
progress is being logged in to a log file

I use alias echo of write-ouput to do shit like this

echo "MOVING THE ARCHIVE..." >> $log_file

recently I realized that I can do just

"MOVING THE ARCHIVE..." >> $log_file

>QUESTION 1
Should I use just that above instead of write-output or its echo alias?

but I feel like its still quite inelegant.
what I would prefer the most is single line where I tell the script to redirect output like in linux bash
but no luck googling, even though it seems possible
but I dont fucking care if its some 20 lines of code, or adds even more shit than >> $log_file

Exactly. I'm displaying what would happen if void* did not need to be cast. It opens a gaping hole in the type system.

C's type system sucked.

>>61274840
To add to this
>>61274873

if you want to compile main.c from say "~/projects/hello" and you're running gcc from that folder, but your program needs to link and include headers from library "foo", located in "~/foo", you would do something like this

gcc main.c -o hello -L ~/foo/lib -l foo -I ~/foo/include

where the last -I is upper case i

>>61274948
C doesn't suck, it just doesn't hold your hand and assumes the programmer isn't a retard and can remember what his pointers actually point to

>>61274975
That's what a type system is for.

>>61274948
You can do the same thing with casts though. C++'s type system is still flimsy. If you want type safety don't use C or C++.

Removing implicit conversion from void pointers doesn't really do anything other than force you to use generics and new, and make interfacing with C libraries, especially those with functional programming aspects, a burning pain in the dick.

>>61274816
Yes I know. Bothering C++ programmers make them less effective in destroying the world though.
You can trivially bother them a lot with simple questions. People are suckers for teaching.
>>61274839
Most who do it really really suck. It's a shame. I'd love to actually learn from other programmers.

I can see why good programmers don't though. It'd be easy to get distracted.

>>61275011
>You can do the same thing with casts though
Casts are explicit. It's fine to do dangerous things if you make it clear that what you're doing is questionable.

C++ tried to have a type system. OOP is all about types. However much it succeeded is questionable, but this hole needed to be closed before an attempt could even be made.

>>61274840
>>61274873
This depends on the compiler. It's not C specific.
But it's true for all the ones I use (MSVC, GCC, clang

public int max(int a, int b) {
  return new If(
    new GreaterThan(a, b),
    a, b
  ).evaluate();
}

>>61275125
God damn. Wow. I guess that would be how eval would work in OOP. What a dumpster fire. I'll stick to Lisp for eval.

>>61275348
IntelliJ IDEA is bretty gud

>>61275348

>>61275311
Remember if you Google flags you need to quote the -l for instance.
Because Google has exclusion terms denoted by -. So searching gcc -l will get you everything you're not looking for.

>>61275273
Sort of. But the problem is you have to operate on objects. Which means performing operations to alter the "source" to be evaluated is going to be a bitch. You can't just use your typical built in parsing operations and whatnot like you can in lisp with map, car, cdr, set-car!, set-cdr! and shit.

(define (max a b) (eval `(if (> ,a ,b) ,a ,b)))

Also I'm wondering if that has support for evaluating in different environments like r7rs does.

Not to mention evaluate not working on source code and easily portable code makes it an unnecessary bitch for many good uses of eval. But that's going to happen for basically any non-lisp language because only lisps are homoiconic.

Now you have to worry about serialization.

It's still cool though. But cool in an abstract way and not in a practical way.

>>61275348
IntelliJ IDEA or NetBeans. IntelliJ is better but you'll have to buy it to unlock everything, Some people also use Eclipse but it's inferior to netbeans. These all run on JVM itself so you can use them in any OS.

>>61275372
Works well for learning and small stuff but once you get into proper projects with dozens of class files you'll understand why proper IDEs are the preferred option.

/dpt/ have you ever noticed that in C++ implementation files are garbage?
>inb4 all of C++ is garbage
If this is what you have to say about it, kill yourself.

ubigint ubigint::operator+(ubigint const &other) const {
    // implementation goes here
}

Why doesn't C++ have a "using typename" or "using class" declaration yet, that you could put in an implementation file to indicate that's the class you're implementing?
It would make this trash so much easier.

using typename ubigint;
ubigint operator+(ubigint const &other) const {
    // implementation goes here
}

Why do schools, colleges, bootcamps etc. still teach Java serialization? It's absolutely terrible and fraught with problems and pitfalls

>>61275413
You forgot to mention that some Lisp implementations are native, so "eval" may be compiled to machine code when needed.
For one call like "If" it would be stupied, but scripts being runtime built to native is very nice.

I wish using D without GC weren't such a minefield, otherwise I'd have hopped over years ago.

>>61275348

Why use a dead language that doesn't function well without a GC, when Rust exists?

>>61275697
just buy a vape and use rust

>>61275704
D's GC is relatively pleasant though.
You can control it, and get around a lot of invoking so you dont have to bother in the first place.

But not that you really need to, desu. Its never fucked me and i do mostly games.

>>61275740
Or you could just use a non-dead language that doesn't have a GC that you have to control or work around.

>>61275723
Rust changes a lot more than just having modules.

So it's even more superior to D.

>>61275751
D is the best current language for games.
Rust is slow, everything is 10x more tedious, and the community care more getting more people in their cult then the actual language.

Im sick of C++'s shit.
My functional languages are currently too slow as well.

I hate this.
I don't want to have women be put above men for their gender. There's arguments around women being unqualified for jobs like firefighting and the likes but programming isn't like that at all.

Also you rarely find men arguing for the reverse. To lock themselves out of jobs. Not to mention the way they miss how women having less jobs to choose from makes them less competitive in the market overall (if you have less options you can't argue for as high a pay for instance).
Horrible comments.

I don't think it's that at all. This guy doesn't have any chance of losing his job to women really (unless his company deals with him for political reasons). He may be a Java monkey but he's high enough to not be all that affected.

It's a genuine protective concern I think. My mom has been working with software for over two decades now. She does fine. But she was a project lead for a while and she didn't back down on her responsibilities ever (meaning she just took on more and more) so like everyone who does that she got horribly depressed and had to take a long leave.

I think his perception is that women would end up there way easier and he doesn't believe programming is a healthy career choice for women. I don't think he's right to generalize all women like this even if he would be right. He should take a more nuanced view. He's not the only one at fault for this. Society as a whole is terrible at this so it's not as bad as he makes it out to be.

I wouldn't want to work on a project with a woman under him though. That'd be stupid unfair if he just throws her work at me. What I'm worried about with PLs like this guy is just that.

What if the person I'm watching provides more value than just playing? (i.e. they're the best at the game, or they're entertaining, or they're further ahead than you are in the game, etc.)

There are lots of reasons why let's plays and now steaming are so big. And gaming has always been a spectator sport for many.

>>61274972

Sorry for the late response, hope this still helps.

Here's your problem. I should've told you how to actually invoke the program. It's ignoring your file and waiting forever for input from stdin.

To give it stdin input, you could type, but that would also take forever. Instead, try this:

./missing_numbers < a.txt

That will pass a.txt to the program as its stdin stream.

>big browser is watching

that's fucking brilliant

Picture this, /dpt/.

Your operating system is now Python.

I don't mean it's written in Python. I mean your operating system literally IS Python.

As in, you press the power button, the bootloader takes however many seconds to do its thing, and this is what you see next:

Python OS 1.0 (default, Nov 17 2016, 17:05:23)
Type "help", "copyright", "credits" or "license" for more information.
>>> _

The system info line is omitted because Python itself is the system.

All the libraries included with the interpreter that have to make use of anything outside the simple shell environment -- filesystem, networking, graphics, audio, etc -- are fully functional and have been reimplemented as unhosted/freestanding. There is no kernel. Python is the kernel. These libraries now talk directly to the drivers.

The exit() function has, of course, been repurposed to shut down the computer.

You can install new third party libraries using a package manager provided as a new standard library. Of course, the package manager must be invoked from the Python interpreter, because there's literally nothing else.

You can upgrade the OS, but here's how it has to be done. There's a dedicated upgrade partition. You -- IN PYTHON -- have to:
>download the upgrade package
>write it to the upgrade partition
>call a function which will:
>>give the bootloader advance notice you want to boot from the upgrade partition next time
>>reboot the computer

Now.

Given all this information.

>Working with strings in C

>>61278775
It never will.

>>61278803
C is a disservice to intelligent programmers. It has almost 0 features that a modern and intelligent programmer uses to be productive. Since C is such a timesink, it's popularity is falling more than any other languages in the market.
C is dying and it should die ASAP. C programmers are actually retards in general. C is a small language to grasp, exactly the kind of shit that makes things retard friendly.
C has no advanced features like C++ does.

But as a newfag you are kinda in the right direction. C is for newbies. Think of it this way:
During ancient times, counting to 10 was a big deal and a person who could count to 10 was considered to be "wise".

Fast forward a few century counting to 10 is so trivial we teach this to toddlers. Now toddlers appreciate the vast "knowledge" of counting to 10 while matured brains are busy with modern technologies.

C is from stone age and the people who still preach it is like overgrown toddlers that can't learn advanced things. C is for lesser programmers.
C doesn't have delegates
C doesn't have resizable arrays
C doesn't have strings
C doesn't have string concatenation
C doesn't have namespaces
C doesn't have exception handling
C doesn't have closures in the standard
C doesn't have unit tests
C doesn't have Function overloading
C doesn't have memory safety of any kind
C doesn't prevent memory exploits and has no bounds and runtime checks
C doesn't support dynamic method loading/creating
C doesn't even have generics and templates
C doesn't have meta programming
C doesn't have mixins
C doesn't have higher order functions
C doesn't have contract programming
C doesn't have inner classes
C doesn't have function literals
C doesn't have array slicing
C has a very limited support for implicit parallelism
C doesn't even have string switches

I was looking at: https://gamedev.stackexchange.com/questions/23312/45-slopes-in-a-tile-based-2d-platformer

And saw the formula:

y1 = y + (x1 - x) * (v / u)

Where:

x1: object x coordinate
y1: object y coordinate
x: tile x coordinate (bottom left)
y: tile y coordinate (bottom left)
u: tile width
v: tile height

I've also been trying too make sense of the part of the article that has the Mega Man X image: https://www.gamedev.net/articles/programming/general-and-gameplay-programming/the-guide-to-implementing-2d-platformers-r2936

I was playing around with several combinations, and couldn't get anything to work as expected.

I don't have any sloped tiles either, I'm not sure how to incorporate those into SDL. However, shouldn't this formula work regardless of whether it is sloped or not?

I think that the issue that is confusing me is that the origin x,y coordinates are from the bottom-left, whereas in mine the origin x,y coordinate are from the top-left. What would I need to change around in order to have a working formula?

I was looking at how to create a directory using C if it doesn't already exist. I got the following answer and it works but why was it necessary to create and use a struct?

struct stat st = {0};

if (stat("./temp/", &st) == -1) 
{
  mkdir("./temp", 0777);
}

Stupid question but sqt are stupider.

When should you use * in C++? For instance when passing a pointer to a function, you don't prefix it with *, but when accessing a member through it, you also don't need *. I thought * meant you get the value (which in this case would be an object) so why don't you need it when accessing members i.e. using the -> operator?

But can you provide the definition of a template function in a source file while having it's declaration in the header file?
I don't think it's possible, considering the way templates work.

So what's the use for declaring template function prototypes? you can never define them.

The function stores the info it gathers on the struct * you give it, if the dir doesn't exist, which is what he wants to check, then if it returns -1, if it does right away then NULL will work, if the dir exist, then it will need memory to store the data and it doesn't have it when you pass NULL. When you pass by address a staticly allocated struct stat it will be alright.

>>61279660
Since there are no 'unsigned' floating points numbers, all adder circuits must have a complementer for the sign bit, and after that it's the same circuitry for adding and subtracting.

so a gpu would most likely use the same circuitry for addition and subtraction, and it probably doesn't matter if you use only addition, half and half, or only subtraction?

Fuck I want to learn C but why is it so unpleasant to work with
I used to think it's just because it's old, but Pascal is even older and has much nicer syntax

Learn Forth. It has very simple syntax really appealing to lispers.

>>61280104
>It's all in the terrible small details and design decisions
What exactly are you complaining about?
A lot of the weird little details in C come from the fact that when they first standardised it, they were just standardising existing common practice, even if it didn't really fit a wholly consistent design.
That's why there are some oddities like gets, SHRT_MIN, and a bunch of others.

>>61279709

First one says, for every unique combination of types, following this pattern, used to invoke this name, ensure there shall be a corresponding block in the program text, but don't define it yet.

Second one says, for all blocks in the program text hence ensured, define them thus.

I know people complain about how it's just an alias, and not actually a new type in any sense.
>having to declare function prototypes on top of the file
Reorder your functions, then. You should only need prototypes in header files, or if you're doing mutual recursion.
>multiple meanings of static
A common and valid complaint. The C standards committee is averse to adding too many keywords, so they reuse shit a bit too much, with static being the worst.
>anything related to headers
That's how shit was done back then, and it's too far late to do anything about it now.
They're not that hard to deal with, though.
>Also some things not intrinsic to the language like makefiles
That's not how shit was done back then, and I still don't think a language like C really needs one.
C is meant to be able to linked with other languages and hand-written assembly. I can't imagine a way that a truly portable implementation of this could exist for C.

>>61280445
>That's pretty core to how C works. You manage your own memory.
Nah my problems with that are much more superficial.
I just wish I could do something like
var something = new(thing);
instead of
struct thing something = malloc(sizeof(thing));
>You don't really need to use typedef a whole bunch.
>I know people complain about how it's just an alias, and not actually a new type in any sense.
What I don't like about it is that there are so many ways to use it, like naming only the typedef and not the struct, naming the struct thing_p and the typedef just thing, or not using a typedef at all and just struct thing everywhere.
>Reorder your functions, then. You should only need prototypes in header files, or if you're doing mutual recursion.
I know, I would just like to have this kind of thing be automatic like in newer languages.

I'm just too fucking used to languages like Java, C# and Go. I'm sure I'll get used to the C way of doing things eventually, but man it's gonna be such a pain in the butt until then.

i didn't read all your your gripes, but modern C++ is quite different than C besides the syntax, and for example you can do auto something = new thing();
