Daily reminder that lisp machines had hardware-assisted garbage collection. Regardless of whether or not lisp was shit, that is a pretty cool factoid. IIRC, Azul is doing something similar for Java servers.

>Master Foo and the Ten Thousand Lines

Master Foo once said to a visiting programmer: “There is more Unix-nature in one line of shell script than there is in ten thousand lines of C.”

The programmer, who was very proud of his mastery of C, said: “How can this be? C is the language in which the very kernel of Unix is implemented!”

Master Foo replied: “That is so. Nevertheless, there is more Unix-nature in one line of shell script than there is in ten thousand lines of C.”

The programmer grew distressed. “But through the C language we experience the enlightenment of the Patriarch Ritchie! We become as one with the operating system and the machine, reaping matchless performance!”

Master Foo replied: “All that you say is true. But there is still more Unix-nature in one line of shell script than there is in ten thousand lines of C.”

The programmer scoffed at Master Foo and rose to depart. But Master Foo nodded to his student Nubi, who wrote a line of shell script on a nearby whiteboard, and said: “Master programmer, consider this pipeline. Implemented in pure C, would it not span ten thousand lines?”

The programmer muttered through his beard, contemplating what Nubi had written. Finally he agreed that it was so.

“And how many hours would you require to implement and debug that C program?” asked Nubi.

“Many,” admitted the visiting programmer. “But only a fool would spend the time to do that when so many more worthy tasks await him.”

“And who better understands the Unix-nature?” Master Foo asked. “Is it he who writes the ten thousand lines, or he who, perceiving the emptiness of the task, gains merit by not coding?”

Upon hearing this, the programmer was enlightened.

>Regardless of whether or not lisp was shit
Just to clarify, it was indeed shit.
>that is a pretty cool factoid
True.

>>59825469
TL;DR
Don't reinvent the wheel.

>>59825618
So you're saying to program in high level languages with garbage collectors?

>>59825634
Yes. Use Lisp.

>>59825656
I'd rather use other high level languages with garbage collection.

>>59825656
Why would I be using a blatantly shit """""""""""""""""""""""""""""language"""""""""""""""""""""""""""""?

>>59825634
No, I'm just saying don't implement something that is already available to you, unless you're doing it for learning purposes though.

In your example, it really depends on the application, if it's an embedded software app then I would try to use a lower level language. On the other hand, if I am designing an interface for some engine (e.g. unity) then I would prefer using something like python.

>>59825668

What is an actually good book on C++ as a first language?

>just Principles and Practice Using C++ bro

I swear this book is a retarded meme. Between the outdated custom header he makes you use that has known bugs, to the "review" where you're apparently expected to google shit he never explained that is so much more advanced than the review it might as well be "jk just read another book or learn programming online", this shit is painful to work through. I keep getting stuck on literally every exercise/drill/review because he conveniently did not actually explain the shit that is in the "review". Surely there must be a better way.

>Master Foo and the Methodologist

When Master Foo and his student Nubi journeyed among the sacred sites, it was the Master's custom in the evenings to offer public instruction to Unix neophytes of the towns and villages in which they stopped for the night.

On one such occasion, a methodologist was among those who gathered to listen.

“If you do not repeatedly profile your code for hot spots while tuning, you will be like a fisherman who casts his net in an empty lake,” said Master Foo.

“Is it not, then, also true,” said the methodology consultant, “that if you do not continually measure your productivity while managing resources, you will be like a fisherman who casts his net in an empty lake?”

“I once came upon a fisherman who just at that moment let his net fall in the lake on which his boat was floating,” said Master Foo. “He scrabbled around in the bottom of his boat for quite a while looking for it.”

“But,” said the methodologist, “if he had dropped his net in the lake, why was he looking in the boat?”

“Because he could not swim,” replied Master Foo.

Upon hearing this, the methodologist was enlightened.

>Master Foo and the Script Kiddie
A stranger from the land of Woot came to Master Foo as he was eating the morning meal with his students.

“I hear y00 are very l33t,” he said. “Pl33z teach m3 all y00 know.”

Master Foo's students looked at each other, confused by the stranger's barbarous language. Master Foo just smiled and replied: “You wish to learn the Way of Unix?”

“I want to b3 a wizard hax0r,” the stranger replied, “and 0wn ever3one's b0xen.”

“I do not teach that Way,” replied Master Foo.

The stranger grew agitated. “D00d, y00 r nothing but a p0ser,” he said. “If y00 n00 anything, y00 wud t33ch m3.”

“There is a path,” said Master Foo, “that might bring you to wisdom.” The master scribbled an IP address on a piece of paper. “Cracking this box should pose you little difficulty, as its guardians are incompetent. Return and tell me what you find.”

The stranger bowed and left. Master Foo finished his meal.

Days passed, then months. The stranger was forgotten.

Years later, the stranger from the land of Woot returned.

“Damn you!” he said, “I cracked that box, and it was easy like you said. But I got busted by the FBI and thrown in jail.”

“Good,” said Master Foo. “You are ready for the next lesson.” He scribbled an IP address on another piece of paper and handed it to the stranger.

“Are you crazy?” the stranger yelled. “After what I've been through, I'm never going to break into a computer again!”

Master Foo smiled. “Here,” he said, “is the beginning of wisdom.”

On hearing this, the stranger was enlightened.

Some interesting things to be found in there. Like there's a print screen key interrupt, and it actually prints the screen to an actual piece of paper. never knew the graphics card did that.
Also there's this one data structure that's used all over the place and I haven't been able to identify it. It's like a pointer to a table with pointers to a table with pointers, etc... Like five or six levels deep. No idea what it does.

Just load a BIOS into a disassembler, then try to figure out what it does. That's all there is to it, really. An interactive disassembler (IDA) helps to keep track of known functions/data, and where they're referenced from, etc.

I know, I should have used polyfills, angular and shit, but I just stuck to old web 1.0 shit that works on every browser, and is retardedly fast.

What /dpt/ is going to get mad at though, is that I made it in Java. With minimalist frameworks that makes you wire up the template engine yourself, if you want one. And using DTOs for data that gets rendered in the pages so that changes to those objects are isolated from the rest of the system.

It's fast, it scales (if you switch RDBMS to something that isn't in-memory), it's easy to use and everyone loves it. Feels good man.

I am also a noob and I thought I would make a simple vidya project to keep me motivated.

Two Python options I've tried are Pygame and Godot. Pygame is just a framework, so you will have to literally develop the engine yourself to make anything more interesting than Pong. I was working through Al Sweigart's books on Python and he has one about game dev in pygame for beginners. The problem is "pygame for beginners" is a dubious idea, since engine development isn't exactly what you think when you think "beginner", it hasn't been much more helpful to me making a real game in the same way that learning to make simple text games in the command line doesn't really help you make real games.

Godot does not actually use Python, it has its own scripting language called gdscript but gdscript is very Python-like, if you worked through a Python textbook it will look familiar to you.

So I guess you could try one of those two things. Eventually I got frustrated for other reasons that may not apply to you and am now learning other stuff.

Make games, not engines

>>59827835

To address the philosophical aspect of what you are asking:

While an expert in C can accomplish much more than a novice in C++, and much much more than an intermediate in C#, they are very difficult to find (the rules about architecture aren't really written anywhere, and there are many of them, etc...).

However, since there is a demand for lots of code - any code, even shitty code - there is also a demand for a set of rules for making that code so that anyone with a brain stem can follow them.

Stupid people need lots of rules to be productive. Professionals make their own rules.

As for those of us who grew into C++ from C, it was due to problem complexity, and because we got tired of writing the same "typedef OBJECT_HANDLE int;"-based API umpteen thousand times over.

if you are making shitty platformer #13901390438 then use game maker. if you don't want to depend on having a license for an existing engine, and if you set realistic goals for what you are capable of doing in a timely fashion, and if you want to be in charge of your game's performance and platforms, and if you want to think about how your game is made on a much deeper level which could lead to a better game and will definitely lead to a better designer versus an engineweenie, and if you don't want to pay royalties, and if you want to decide if your game still exists in 10 years or not, and if you bought the freedom meme, and a million other reasons, make your own engine.

I am mostly talking about 2D though. I posted a pic of jonathan blow as a joke because some of those are his arguments, but this dude develops 3D engines which is some next level shit.

>>59828122
I think I agree with you but it should be stressed that "make your own engine" and "make your game without an engine" are kind of two different things. Trying to make just an engine, no game, is a waste of time. You'll bumble around implementing random features and end up with something either too specific to be used as an engine or something too generic to benefit from doing it yourself much. Also nobody will use it if there's no proof it works.

What kind of GPU? Where did you get the bios?

Threading question

I've got some thread:

void *foo(){
    char *s;
    FILE *fp = fopen("file.txt", "r");

    fscanf(fp, "%s", s);

        //printing s here will print a string, e.g. "abc"

    bar(s);
}

void bar(char *string){
    fprintf(stdout, "%s\n", string);
        //this prints "(null)"
}

so the pointer is somehow not getting passed from the thread to the function? How should I do this?

shitpost :: g_dpt -> String
shitpost x y 
  | x>0 = read_shitpost x $ get_shitpost x y
  | otherwise = goto_catalog

How'd you git gud at IDA? I've got The IDA Pro Book and I use it a lot for making game cheats, but I still find it kind of overwhelming. I made a zoomhack for Path of Exile by tracing the zoom function back to two cmovbe instructions and I switched them to plain mov instructions, so now it will let you zoom out farther than 1(max zoom value).

It's from an old 3dfx card. Nothing special, but its registers are well documented. Check this out:
http://v3tv.sourceforge.net/download/voodoo3_spec.pdf
I wonder if there are any data sheets like that available for modern cards.
Getting the bios is pretty easy. Either read the chip directly with an eeprom reader, or do a memory dump from a running system. The video bios is located at a fixed address C000:0000 (or at least, used to be, idk if this still holds for uefi).

>>59828206
I think it stores data specific to each video mode somehow. In some easily identifiable functions (eg. "write character to screen") you'll see it pull a value somewhere deep from the pointer pile and then use it as an index to a jump table to select the appropriate sub-function for the current video mode.

>>59828313
I wouldn't call myself gud by any means. Just figuring this stuff out as I go. idk anything about game hacks but that sounds like a neat trick though. A video bios is probably super simple in comparison.

Why does the c++ compiler think that my std::set is const? Is it because the method itself is declared const? How can I return a non-const std::set?

Quick question that's driving me mad
I have program A that is 64-bit and running a custom add-in I've made for it
program B is 32-bit only, and I want to query it from program A for specific data

On execution, I always get a "REGDB_E_CLASSNOTREG" error, which from what I gathered is because the COM setup for B is 32-bit and my project is 64-bit
Any thoughts on what to do? I can't just re-configure the project as 32-bit since it breaks program A

>>59828715
Your function is const, so your "this" pointer is const, you can only return const values.

My manager doesn't have a manager.

I work for a small company that does not primarily do software development for clients, and we do not outsource. Also, I have no need to "own" software. Personal projects I do are open-source as soon as they are presentable.

Lastly, I would have no desire to own these myself; they are very specific to the company, yet still very satisfying. I guess I could go on with a cynical view like yours and hate everything, though.

>>59828880
Your hiring situation isn't typical.
Software workers are regularly asked to sign away all rights to all software they write during company time or on company equipment.
Some even go further and ask to embargo your personal projects outside of work as a form of "no-compete clause", though this is expressly illegal in places like california.

>>59828920
Well, you ought to ask before you assume the situation, then. I would have a hard time accepting a position that tries to own my out-of-work code. I'm not desperate for a job in the slightest, and I'm confident that my skills have basically anchored me a position whenever I need one.

The only reason I can see someone accepting such terms is that they are in a position of weakness and desire the job more than the job desires them, or it's a job with insanely high pay/perfect location/great benefits, in which case one ought not to care about that issue too much because they are being fairly compensated for it.

>>59828743
>>59828749
Okay, a follow-up question. When exactly do I use const methods? Only when not returning anything?

Let's say I return a class Baz. It seems really limiting to return a const Baz if I have to call Baz::someMutator(). So when is it feasible?

>>59828974
const methods can be called on const objects.

>>59829009
Most of my methods actually alter the state of the object, however. Is there like a rule of thumb?

>>59829071
If the method doesn't require "this" to be non-const then you can make it const. It's not a very difficult concept.

>>59823614
>>59824103
I improved on the solution to this problem:
https://hastebin.com/hutupiwoze.c
I made it print out the correct sequence now,
used a switch selector instead of if selectors,
and implemented a data structure.

Feedback is appreciated.

>>59828974
const is really just an 'agreement' (i.e. compiler enforced) to not modify the object through the returned reference. Say you have a complicated class that you have very specific ways of interacting with the underlying object(s). But, someone wants to read ALL the information contained in the object. You would want to have a read() method that's const, so that they can't modify the underlying object (either implicitly or explicitly) without going through YOUR interface (considering something like keeping track of the total # of orders in a database, minimum date of sale of all entries, ect).

>>59829115
>switch case inside for

for what reason

>>59829092
>>59829127
I think I get the idea, but I can't seem to understand how (or if) I would implement it in any of my own projects.

Let's say my class Car has the following method:

Tire getFrontLeftTire();

and Tire has the following methods:

int getPressure();
int getWidth();
void deflate();  // Alters the state of the Tire

Most of the time I just want to inspect some data, without modifying the Tire. 1/1000 times, however, I want to deflate it for some reason. Is it the right thing to do, to NOT make Car::getFrontLeftTire() a const method?

>>59829241
Returning a const Tire is different from making the method const.

>>59829261
I know that, but nevermind. Can't fucking word my problem.

>>59829295
getPressure and getWidth could be const. getFrontLeftTire could be made const if it returns a const Tire (presuming the Tire is a field of the object). It's possible that you would want both a mutable and const version of getFrontLeftTire.
