You don't have to be smart to compete in the market. You just have to be dishonest, not care about morals and be willing to cheat. Just like Bill Gates and Microsoft did. Capitalism doesn't reward excellence, it rewards foul play.

You have to be smart and competent to create robust quality stuff like Linux, which according to your criteria, isn't as great as Windows because it hasn't made as much money or isn't as popular, even though it is objectively a superior piece of software.

ROFL. The world would be fucking filled with billionaires if that were true.

No. Being dishonest and not caring about morals is being smart enough to realize the nihilistic nature of the world and make full use of it.

>You have to be smart and competent to create robust quality stuff like Linux
You have to be even smarter to see and correctly measure trade-offs between complexity and their worth, to find what people need and do it their way, not what you find easier to implement.

>robust quality stuff
>Linux
LOL. Linux is utter crap. You want a robust kernel? Try SEL4.

You've just proved yourself wrong.

Keep in mind, I'm not saying it isn't great. I'm dismantling your false premise that the market rewards excellence.

It's great by your standards. You prioritize technical excellence over pragmatism, which is retarded. You should be an artist, not a programmer. Why aren't you using SEL4 instead of Linux? Or did I misunderstand you and you are using Windows?

>I'm sure all those Wall Street bankers are super righteous people, anon.
No they're not and I did not imply they were. They superior people than most other people, though.

How about we compare him to his contemporary and rival Gary Kildall? Who was obviously more competent than him, but was commercially defeated by Microsoft's foul practices?

>>61711865
I'm usually a fan of Joel on software, but a lot of his points about not rewriting might not apply here.

His main points are that poorly written code is usually bug fixes, and that older code isn't all bad, because it's battle-tested.

From what the original anon said, it sounds like there are still a lot of existing bugs, and 1.5 years isn't that long of a real world presence.

That said, you should be sure that a rewrite is definitely the best option. It might be best to come up with an idea of how the architecture of the program should ideally look. Then consider again whether you really need to rewrite, or whether refactoring the current codebase will produce a similar result in less time.

>>61712019
Hungarian notation can actually be useful (and not just for dynamically typed languages), but basically Microsoftruined it, so that most people use it wrong. Worth a read if you have time:

does bash support OOP?

>61712369
>And just as I expected, you missed the point.
You missed the point. The point was if you truly appreciated technical excellence, you would be using those "technical excellence" programs. And your previous posts suggested you are using the Linux kernel, which is objectively inferior to SEL4. Why? Because without even realizing it, you prefer commodity over this "technical prowess", as you say. You're just virtue signalling.

The point is, that fundamentally, capitalism is *always* right. The *best* product gets the most marketshare. Linux was *objectively* worse from a simple users perspective. Linux is objectively *better* from server's perspective, and the marketshare respects that.

How do you guys start a project when you have absolutely no fucking idea where to start?

I am trying to write a program in C that takes user input and prints a histogram of the lengths of the words.

Here is what I have so far:
https://hastebin.com/ixomedejuq.cpp
This will get me the number of words in the input, but I'm stuck in regards to keeping track of the word lengths and displaying the histogram. Since this exercise is in the array section, i assume I'm supposed to create an array to store this information, but the array length of course depends on the input, and once my while loop reaches EOF, as far as I know, I can't access the beginning of the input again with the getchar() function.

Any advice would be most appreciated.

I don't I understand objects and classes fully. I'm looking at an example involving a shopping list with items on it.

So the shopping list would be the object shoplist and the class would be the thing after it, right? like if I typed shoplist.append('rice') the rice would be my class?

what is an imageviewier? a program that

- load a image file
- unpack the pixels into a drawing buffer
- render the drawing buffer to the screen

so you have to learn

- about image formats (PNG, BMP, JPG)
- how to create a drawing buffer (SDL, Opengl, GTK, Qt, ...)

only after that, you will then think about adding features and designing a GUI.

>>61712843

>>61713288
Say you want to model a solar system in your program. You want to describe ho

class Planet
{
    var mass;
    var radius;
    var gravity;
}

The "Planet" class is a blueprint that describes what a planet looks like, what it can do, what information it must contain etc.
When you actually create some planets:

var Mercury = new Planet();
var Venus = new Planet();
var Earth = new Planet();

All of those are objects. They are examples of planets.

>>61713301
a class can be viewed as the description of an object

class Foo:
  pass

foo = Foo() # foo is an object instanced from the class Foo
bar = Foo() # Bar is another object instanced from the class Foo

# bar and foo are not the same object but are from the same class
print( foo == bar ) # False
print( type(foo) == type(bar) ) # True

>>61713577
C11 for primary language, Python for generating models. OpenGL ES 2.0 as graphics API, GLFW to set up the context and keyboard/mouse input. libsoundio for audio. Nuklear for GUI. For now there are no textures (my first game won't use any), and sounds and music will be raw pcm to avoid needing any additional libraries. Physics for now are not integrated, but later on I will probably bind chipmunk for experience and then try to make my own 3D physics engine (after physics course in uni).

it has its place just like python does.

I just had to write a script last night that recursively traversed by web domain searching for incorrect URLS and rewrote them with the correct one.

I used python.

Sure, I could have done it in c++ and spent 2-3x as long writing and testing the program, but why?

its like working on machines, sure, you can use channel locks to turn a nut, but you really should be using a wrench.

Every language has its advantages/disadvantages dont listen to the sour autists on here, learn every language that interests you and then you can use the right one for the job when you need to rather than limiting yourself to fixing everything with a single tool

In my class definition I said that a Planet must have a mass, a radius and gravity.

class Planet
{
    var mass;
    var radius;
    var gravity;
}

Any time I have a thing which is a planet, I should be confident that I can get each of those things from it.

earth.mass // 6 × 10^24 kg
venus.mass // 5 x 10^24 kg

In a dynamic language like Python, you can easily add additional variables or functions to an object. In a static language like Java, you can only do to an object what is specified in its class definition. I suggest looking into Java if you're still struggling with the idea of OOP. It's very heavy on keywords and syntax but I think that helps to give you the right idea.

There is no free framework I can rely on that I know of (SDL/SFML/Allegro). All work for 2D, not 3D (which I plan on moving to when I'm confident with 2D) and won't be sufficient in control and performance when I want to expand. I use libraries when I can justify them, so not to burden myself with a big dependency for a couple of functions.

With the big engines (free ones being Ogre3D for rendering and Bullet3D for physics), the learning curve is so high it basically vendor-locks you and I doubt they're a good approach when you're learning on your own.

I think my approach of making a small engine for a small game and expanding it over time is a rational approach. I can't make a block-buster making on my own, but I can expand slowly.

C++ will be most applicable to extending your knowledge to a wide area of programming. its syntax is similar to other C's (obviously), java, and others.

It has the disadvantage that if it is your first language the compiler will be unforgiving and give you cryptic error messages. It also has the disadvantage that if you are not actually reading a book on it while you use it you can very quickly develop horrible programming habbits (memory leaks from not releasing memory for example)

if you learn in interpreted language like python it has the advantage that syntax is easy to understand and you can develop programs quicker and easier and there is large community support for it. It also handles most of the heavy lifting for you, like memory. The interpreter is also easy to work than a c compiler.

It has the disadvantage that its syntax and form is extensible only to a few small progamming languages, BUT the basic idea and knowledge of programming and how it works can be taken anywhere.

if you use a low(ish) level graphics library like opengl or sdl do you need another library to create the window and shit or is that included in those?

just use a SQL branch. SQL can be a little bit slow for queries on large databases its important you have a RAID array configured.

If RAID isnt an option, and fast queries on large databases are required use Redis.

Sql pros: easy to configure, persistent
SQL cons: can be slow

Redis pros: very fast, resides in memory not disk
Redis cons: only memory persistent (i.e. it loses its databases after a reboot unless if you take precautions)

        //The (n)th state of the keyboard key
        bool is_down = ((l_param & (1 << 31)) == 0);


        if (is_down)
        {
            /*
            Single key

if you care about long-term key state as opposed to handling instantaneous presses, you should see if there's a way to get the state of the whole keyboard and check specific parts of it. If not, you may want to write your own (should be simple)

that way, rather than storing little vars, you can just do if keys['w'] && keys['x'] or something like that.

>Sacrificing the convenience of 99.999% of programmers for the 0.001% of machines that practically nobody uses.
But that's exactly the thing though, Anon; nothing is lost. You are aware, of course, that what the standard specifies as "undefined behavior" doesn't have to mean "crash" or "bad things happen", but also that implementations are free to define well-defined behavior in those cases. On twos-complement machines, signed-integer arithmetic is indeed perfectly free to overflow in well-defined twos-complement ways, so you can write your algorithms that depend on that merely by sacrificing compatibility with the machines that you didn't care about to begin with, while the standard language can remain possible to implement on them as well.

>Like what?
Such things as 8-bit PIC micros and x86 in real mode lack linear memory models, and people still write code for those. Here too, though, you can obviously rely on linear memory models simply by sacrificing compatibility with machines that don't have that, losing exactly nothing.
>Also, what machines don't use 2's complement?
No current ones, probably, but C has run (and probably is still running) on tons of historical machines that didn't.

>Also, it's 2017. #include <threads.h> is not implemented in the most widely deployed libc, the mingw wrapper.
That is a disgrace for glibc, yes, I don't dispute that.

Let's saying I'm working in a language that supports direct pointers, and I have a couple parts of a struct I want to be updated individually by several different methods running in parallel.
They're all modifying unique parts of the struct so them fighting over individual values shouldnt be an issue, right?
What would be a good way to wait for them all to finish before continuing onto the next struct?

Shitty pseudocode

struct test {
    int var1;
    int var2;
    int var3;
}

addToVar(int* var) {
    var += 1;
}

main() {
    test teststruct = test{};
    newThread(addToVar(&var1);
    newThread(addToVar(&var2);
    newThread(addToVar(&var3);
    print(teststruct);
}

>>Also, what machines don't use 2's complement?
>No current ones, probably, but C has run (and probably is still running) on tons of historical machines that didn't.
Also worth noting, however, is that GCC uses the undefined behavior of signed overflow to implement both its -fstrict-overflow and -ftrapv options, which are Nice Things. In languages like Java or (((Rust))) which don't allow those kinds of freedoms, you literally cannot have such nice things.

How do I get VC debugger to work with Qt Creator on Windows? It's not detected in debuggers/toolchains so I was told to install MS SDK but that didn't solve the issue.

why does windows reverse the bit when loading memory from register??
or something like that, i know for one that windows use GBR instead of RGB exactly for this reason

>>61714755
Atomic counter might be a good choice?
Basically the problem I'm running into is it's not just occurring sequentially. The ideal is to have 1000 test struct struct's, then like 15 "main" methods where all the threads are spawned to send them the struct off in parallel to be modified, then once everything is done send it off elsewhere (the function no longer cares at that point)

Would using atomic counter work for that, or is that more of a "you have one global thread with this and use it to sync many other threads" sort of thing?

>>61714899
Yeah basically what I meant you could do something like this:

atomic<int> counter = 0;

void thread_func()
{
    calculation
    counter++;
}

void thread_main()
{
    while (counter < desired_value) {
        yield
    }

    threads finished work, continue whatever

I'm really sick and tired of people treating C and C++ as one language.
Just fucking stop, they're two different languages, that have been different ever since C++ was created.
Sure, C++ may be “compatible” with C code, and your C++ compiler may be able to compile C code if it wasn't too complicated, but that doesn't mean they're the same.
There's no such language as “C/C++”, yet I find this shit everywhere online. I search for something about C online, and most results have C++ in the title, and then I have to add -"C++" to my search query.
Don't people understand that?

C++, or as I've recently come to call it, C with objects

I had to write that post here to realize that in my country, when doing PhD studies... it's fucking too much. I'll stick to my lowest scholarship which is about 400$ per month, finish studies and then think what's next. There's too much work related to research to do some side programming for $$$.

>SQL can be a little bit slow for queries on large databases
Thanks for not providing any information to actually quantify that. You remind me of this http://www.mongodb-is-web-scale.com/.

Work out what questions you want to ask of your data and choose an appropriate data storage format that allows for efficient querying. RDBMs are not 'a little bit slow for queries on large databases'.

>If RAID isnt an option, and fast queries on large databases are required use Redis
Your disk does not make a tiny bit of difference if your working data set plus indices can fit in memory.

> Redis pros: very fast, resides in memory not disk
Redis does provide persistence in the form of regular snapshots, but it might not provide the durability guarantees of a regular RDBMS.
