>>60705491
Python first purpose was to be the programming language of Amoeba, an experimental operating system by Tanenbaum. Python never was intended to be an educational language.

""
My original motivation for creating Python was the perceived need for a higher level language in the **Amoeba project. I realized that the development of system administration utilities in C was taking too long. Moreover, doing these in the Bourne shell wouldn’t work for a variety of reasons. The most important one was that as a distributed micro-kernel system with a radically new design, Amoeba’s primitive operations were very different (and finer-grain) than the traditional primitive operations available in the Bourne shell. So there was a need for a language that would “bridge the gap between C and the shell.” For a long time, this was Python’s main catchphrase.

>>60705618
>language gets posted

>>60705618
From the top of my head
- No generics

- Lack of proper type system with ADT and pattern matching

>>60705618
It's an insult to Lisp.

>>60705640
But it was also strongly influenced by ABC which was a language created for teaching purposes.

>>60705626
This was brought up, more politely, in the thread before. Basically it comes down to the fact that since it makes viewing lots of files at once much eacher(and getting them in and out of view, or as in view as they need to be), combined with contextual abilities such asclicking build above a file in one project building that project in specific and being able to jump to the line and file where errors occurred by middle clicking; that it ends up just being a faster and smooth process than I had with vim. Some processes in vim were faster of course, but the overall ease of use just works out better.

If he says so?

have you read the three links from *TOG? He spent 50 millions of dollars on R&D at Apple where he did extensive tests that showed that using the mouse is more intuitive and faster than using the keyboard.

for example

""
The test I did I did several years ago, frankly, I entered into for the express purpose of letting cursor keys win, just to prove they could in some cases be faster than the mouse. Using Microsoft Word on a Macintosh, I typed in a paragraph of text, then replaced every instance of an "e" with a vertical bar (|). The test subject's task was to replace every | with an "e." Just to make it even harder, the test subjects, when using the mouse, were forbidden to just drop the cursor to the right of the | and then use the delete key to get rid of it. Instead, they had to actually drag the mouse pointer across the one-pixel width of the character t o select it, then press the "e" key to replace it.

The average time for the cursor keys was 99.43 seconds, for the mouse, 50.22 seconds. I also asked the test subjects which method was faster, and to a person they reported that the cursor keys were much, much faster. This was a classic example of the difference between subjective time (the passage of time the user experiences) and objective time (the passage of time the clock experiences). Put simply, the more mentally engaging the task, the shorter the time appears.

Could anyone give me the rundown on Mooc.fi? I kept hearing about their Java course being good, I started 2 days ago and I'm already almost on week 4. There's hundreds of exercises but so far I've worked through every single one of them without any real difficulty. It's nice because the sheer volume of exercises reinforces syntax familiarity, but I can't tell if it's really improving my actual programming skills at all. In the almost hundred exercises I've done, not once have I felt even half as challenged as I did doing just the first 3-7 assignments from the CS50 Harvard course on C.

Does it get harder? I want to finish it just to say I did something from start to finish, but I don't want to waste valuable time.

What kind of programs are those, anon?

>>60706853
Even looking at your code for 5 seconds I immediately see that you're writing C with classes instead of C++. Learn C++, with all the nice idiomatic stuff that comes with it.

Some small things:
* Don't malloc without a very good reason. Prefer not to use the heap, or when you have to, new with a smart pointer or some shit. Also the malloc you did allocates the size of a pointer, not the size of the actual object.
* Do RAII, don't make objects with a zombie state, for which you then have to fill in an arbitrary amount of members with `foo->bar = cuck` in order for them to work properly. If I had to work with your code, then I'd have absolutely no clue what magic buttons to press before it works without going through your entire code.
* Don't define without a very good reason. For a string constant use a `const char[]` instead.
* Prefer enum class to raw enums
* Prefer references to pointers. References means less worrying and more dereferencing (if needed, try to avoid raw pointers) in a higher scope.
* Nice memory leaks. If you have to work with heap allocated stuff, make sure you clean it up in a destructor. That way, when an object leaves scope, it's ALWAYS cleaned up (unless you abort or get fucked by SIGNALs or something)

>>60707288
>* Prefer references to pointers. References means less worrying and more dereferencing (if needed, try to avoid raw pointers) in a higher scope.
C++ references are fucking retarded though. It is seriously one of the biggest misfeatures of that giant clusterfuck.
Why would you tell someone to use them, let alone C++ at all?

>>60707451
k tard

>>60707451
Not him, but I'm often torn between references and pointers. Usually I lean towards pointers because I'm a control freak and I feel like pointers provide me with more control (and with more ways of shooting myself in the foot).

Could you elaborate?

>>60707451
I would recommend pointers instead, makes it clearer when you're referring to an existing structure and when you're handling a new one.

>>60707469
>>60707487
C++ references are literally invisible state changes.

>>60706738
>electron
why would i use that in place of imgui?

>>60707487
>>60707514
You should use references wherever you can because they can't be null, you should annotate the use of non-const references in the code tho.

>>60707451
>C++ references are fucking retarded though.
pls explain.

I personally like them because it combined with the const keyword allows you to express intention really well, and means that the user of the reference doesn't have to worry about it being in a null state or some shit.

const ref = You can use this object I pass to you without modifying it.
ref = You can use this object I pass to you, and are free to do with it as you please.

Using references just means less `if (foo)` checks since it's guaranteed to be valid.

>>60707451

I like explicit pointer usage because of the separation of value and reference semantics, it's always clear what the handle on your data is that way.
But without references we wouldn't have good stuff like operator overloading. And I don't see how move semantics could have worked.

>>60707514
>makes it clearer when you're referring to an existing structure and when you're handling a new one.

Wut. References always indicate that you're using an existing structure, right?

same for pointers?

>>60707571

You have to refer back to the declaration to know. "Looks like a value, acts like a pointer" is not a good trait.

>>60707585

int a = 10;
myfn(a);
assert(a == 10);

Tell me, is this assertion true?

>>60707586
But if you want a parameter to be passed as a value without a needless copy taking place, you just make the parameter a const ref, no?

>>60707613

Yeah, const references are harmless enough but I feel like they damage the purity too much.

>>60707604
So your gripe with references is that you don't annotate that you're passing a reference like you would with normal pointers (using &)?

That's understandable, I suppose. Thanks for explaining.

>>60707604
stupid example. first, you would not use myfn without know what it does. second, it would be the same with a pointer (

myfn(int *n)]/code]). this is why you have const.

>>60707632
What defines purity for you then? I personally think that it's great that a language allows you to so firmly express the intent of a parameter like this, since it tells whoever makes use of your function what you aim to do with the object, without them having to look further than the function signature.

>>60707649

To pass a pointer you'd have to do myfn(&x). That's explicitly declaring that my x might mutate, since a reference is being passed.

>>60707649
It's more for when you're reading code later, or code you didn't write yourself.
All of this invisible garbage and implicitness makes C++ MUCH harder to reason about.
If I see

int a = 10;
myfn(&a);
assert(a == 10);

I would think "I see a pointer being taken; the value of a might change".

>>60707671
>>60707662
>I would think "I see a pointer being taken; the value of a might change".
and what would you do then?

References are good but implicit casting to non-const references are bad. In my C++ code, I always annotate every use of non-const reference, like

 fun(/*out*/var); 

, this is why I kinda like Rust's requirements to explicitly use & and &mut to cast a value to a reference, even if it clogs the code somewhat.

>>60707655

It should be clear what everything means at a glance.
If I see fn(x), I should know that means my x won't mutate. If I see fn(&x), it suggests the opposite. If I see x.doThing();, I want to know it won't have side effects outside of my scope like x->doThing();.

Value semantics are one of the most powerful features of C++ over many other OOP languages so I think it's helpful to be clear what is a value amd what is not.

>>60707690
I would be able to make better conclusions about the state of the code, and possible execution paths it might take.

>>60707721
I personally don't mind having to look at the function signature to figure that out, but I can definitely see why you think it's shit.

>>60707514
Use reference wherever you can, pointers wherever you must. Using pointers is rare in modern C++.

>>60707853
This is some of the most retarded non-justification for references I have ever seen.
How can you take those WG21 fucks seriously?

>>60707837

I'm not the original guy.
const Foo& is useful because you get one less copy and the guarantee of no mutation. Foo&& is useful because the original Foo won't live long enough for you to see the mutation. But Foo& breaks the rules, so I prefer against using it.

>>60707872

Removed the redundant words.

>>60707540
I don't see the big deal with the fact they can be null. If its possible to pass in a null value, then your program should handle it in some way, be it via an assertion or an error return code.

>>60708014
in racket

(displayln (~a (+1 2 3) "A"))
or
(printf "~AA~%" (+1 2 3))

i think chicken scheme has printf

otherwise

(format #t "~AA~%" (+ 1 2 3))

see https://srfi.schemers.org/srfi-48/srfi-48.html

>>60708189
That's a lot of checks for something you already know at the compile time, namely, that the reference can't be null.

>>60708189
>>60708220
The key point is, using references forces your calling code to be correct. It changes the design in a way that you know to be correct. There's no possibility of it being potentially wrong/null

>>60704655
I'm probably the smartest person in the room. Just saying.

>>60708235
>using references forces your calling code to be correct
An assertion does the same while keeping the code clearer to read (as discussed earlier.) Besides, its not as if references are completely waterproof either.

int *n = new int;
*n = 3;
int &nr = *n;
delete(n);
/* What's does n point to? */

Null pointers are hardly a problem and if they are, a null pointer error is extremely easy to detect. Its another thing with invalid pointers, and references don't protect from that.

>>60708360
> An assertion does the same while keeping the code clearer
How is it clearer if it's just an additional line with assert? Then again, static guarantee >>> run-time assert in any case.

>>60708389
Clearer as discussed earlier, in that while working on the insides of the function itself, a pointer is more easily distinguished from having been passed in by reference rather than by value. Its the syntax with references that bothers me, in that you can't tell just by looking at the use of the object whether or not its an existing object or something in local scope.

>>60705284
Which dialect?

>>60708415
Well, I agree, implicit casting to/from reference was a mistake. Still, I think it's better than the shit you can get yourself into with raw pointers.

I'm not aware of any standard C function that modifies an argument without taking a pointer to it first.

Only ONCE have I ever run into a library macro that modifies its arguments in a weird way without making you take a pointer to it first, and that was ncurses.

Are there any articles for memory management with custom networking protocols built on top of UDP?

I need to implement a UDP server that can handle quite a lot of users (hundreds), but I'm really uncomfortable with the memory management part. Should I really just malloc every packet and keep it in memory until it gets acked (or is too old to be valid for an ack)? Should I just have one large memory pool for all the users' packages, or separate, per-user pools? I've done small scale UDP before and there, per-user memory pools were valid, but I don't know how valid they would be with a larger amount of users.

Any pointers?

What's wrong with TCP or SCTP if you need acks anyway?

I just made game loop class but instead of making the update and render functions overloadable methods I made them attributes that are lambdas.
So instead of making your own class that inherits the loop you just instantiate the loop and assing the attributes some lambda function.

How bad of design is that?

Its a real-time app so there are some messages that are time-critical, but don't need to be super reliable.

>>60709633
Its not any worse than virtual methods certainly, though relying on lambdas smells a bit of the old "using a feature just because its there" syndrome.

Anyway, in both cases you would only have one instance of the object in total, so either method is fine. I've made some game engines and usually for the different game state's I've made a struct that has a couple of function pointers in it (update_and_render() etc.) Which is essentially the same thing.

I'm not in the industry or anything but the fact that Java is the most taught language at universities and has virtually become the standard should be a hint.

Intuitively thinking, that and the fact that programmers are required to work together as groups should mean that in all likelihood the best language to learn if you want a job is simply the most popular. Going by this logic the best choices are probably Java and Python. Again, this is if you just want "a job." You're more likely to be hired if you're proficient in a language people know about because it's popular, and if you use the same language as the other guys on the team, so statistically it's simply more likely to land a job with the most popular language(s)/languages taught at universities.

By contrast if you're an some elitist programmer who only uses Lisp and Assembly or something you might be leagues better than the Python and Java scrubs but employers aren't going to care if you can't work with them.
