Repost from last thread:

Why does this macro not properly return when passing in an arithmetic expression as a parameter with the visual studio compiler?

#define MIN(val, min) ((val) < (min) ? (min) : (val))

short x = MIN(0 - 32 / 2, 0);
short y = MIN(0 - 32 / 2, 0);

The above code leaves x and y at value -16 instead of 0. What am I doing wrong?

>>59734700
Also, this works correctly if I first save the results of the expressions in variables, then pass those to the macro, so I assume this must be about how the macro expands. But I've got braces all over it, so where is it going wrong?

>>59734700
put parentheses around 0-32

>>59734751
Its supposed to be 0 - (32 / 2) actually.

How do I print things in C without including the BLOATED stdio?

>>59734780
How is stdio bloated?
Also, if you truly want to "drop" stdio, you're going to need to drop the entire standard library.
The answer to your question is the write syscall, but the way.

>How is stdio bloated?
That shit adds 2kb of BLOAT to the binary. It's pretty crazy. Just printf alone calls a ton of shit and fundamentally ends up at putchar.

>Also, if you truly want to "drop" stdio, you're going to need to drop the entire standard library.
>The answer to your question is the write syscall, but the way.
FUCK the standard library desu there's nearly nothing useful in it. I can do my own string comparisons better than that BLOATED POS.

>>59734880
Well you could use some other implementation like musl.
You could also use libraries like tbox or pjlib that basically redefine the standard library.

>>59734880
>That shit adds 2kb of BLOAT to the binary.
Simply using stdio isn't going to increase binary size, at least any more than using any other function.
The standard library is a single library. Each of the headers aren't independent; you link the whole thing.
>Just printf alone calls a ton of shit and fundamentally ends up at putchar.
Sure, but it's usefulness far outweighs its supposed drawbacks.
>FUCK the standard library desu there's nearly nothing useful in it.
Enjoy your freestanding C, then.

what the fuck are "data transfer objects"?

Hello /g/

I have realized that after a few years of programming and studying, I have never actually wrote anything that would have a GUI - since most of my work is either scripts or lowlevel programming. So I decided that I'll learn how the GUI libraries work.

I'd like to write either in C/C++/Lua/Python. Which libraries are good for general usage? I heard Tkinter for Python is the standard but then everyone who writes in Python told me it's hella outdated and surreal - so where do I start to figure out how these things work?

somebody take a look at my shitty C router and tell me why I'm getting a seg fault:
https://pastebin.com/WKBikpD4

valgrind output:
https://pastebin.com/KmBirKCs

>>59735110
More or less cargo objects; objects used to hold data as its saved to/ pulled from/ shaped for insertion to databases, marshalled/unmarshalled from something, etc. Basically a jumped up data structure

>>59735131
I should also clarify, I'm just trying to successfully run it right now, so I haven't populated my 'routing table' yet with proper values.

>>59734157
Just finished pushing out the latest version of my experimental chatbot (FadelaBOT). Still far from mature, but a little more stable, and a little more functional.

>>59735131
>shitty C
That's redundant.

>>59735079
>https://teachyourselfcs.com
Never tried it but looks ok based on where some of the modules come from/who is leading them. What have you got to lose?

>>59735110
>>59735143
>objects
>>>/r/ibbit

>>59735143
right, so stuff like:

class LoginRequest
{
    string username;
    string password;
}

that are only used in a single method for parameter binding or some shit like that?

>>59735171
yeah, go fuck yourself. like it or not, a lot of software is OO, get the fuck over it, your FP revolution still hasnt happened

>>59735110
pretty much self-explanatory. they are data transfer objects. used locally, they are primarily for decoupling logical 'layers' and modules in a system.

How much do you worry about the performance of the code you write?

>>59735155
>blames his shitty programming on the language
fuck off retard

>>59735193
Who are you quoting?

>>59735189
barely. code can be optimized later. on the first write it's more important to just push it out as long as you aren't doing anything silly and extremely poorly performing.

>>59735181
>like it or not, a lot of software is OO
So? It's all garbage.
>your FP revolution still hasnt happened
Where did I say anything about FP? Or does your plebbit mind for some reason think it's the opposite of POO?

Rust is the future!

>>59735180
Well its a bit stripped back but essentially yeah. They're something of a code smell, AFAIK they came about when EJBs first came out

>>59735124
Tkinter for Python is fine if you've NEVER done anything with a GUI before. http://www.tkdocs.com/tutorial/
It's pretty old and wild but this documentation site has everything you'll really need to get started. You can move onto Qt later for C/C++ and Python.

>>59735215
It's lacking about 20 years to be called that.

>>59735237
in rust you have to choose between safety and doing anything useful.

>>59735240
That's good then. But is it a good place to start? Or should I start with something else? I am not really planning on writing anything with a GUI, just literally want to find out how modern GUIs work

>>59735213
Nope but generally autist faggots like you who have major issues with OO usually espouse FP as the saviour. I assumed since you seem as retarded as those guys, you must be one of them. And nobody gives a shit if you think they're all garbage, your opinion won't change anyones mind, get the fuck over it

What did you mean by this?

>>59735259
It's not my opinion, I actually disagree with that and I think OOP is pretty good. But the reality is that POO is garbage and so is everything written in it.

>>59735294
ah, I was wondering what rust had to do with DTOs for a minute or two there

>>59735294
Even if you write all your code in unsafe in rust it's still miles better than C11

>>59735302
So you like OOP, but you think software written in OO fashion is garbage. Jesus you're worse than the FP fags, at least they have integrity

>>59735318
I like OOP, but I acknowledge the reality of it being absolute garbage.

>>59735331
why is it garbage?
HARD MODE: You're not allowed to google "why OOP is bad"

>>59735331
And? So nobody should discuss OO tasks or topics? What point are you trying to make here?

>>59735013
Tried that too, same result. Can't try now though because not on a windows machine.

>>59735311
Rust will never take off as a community because it's simply up against too much momentum from C and C++. No one is going to change languages unless there's a very good argument for it and their codebases can be easily converted. Also Rust is not a simple language like C is at its core and thus you're never going to get the C crowd on board since they like C because the speed and simplicity of the language.

>>59735357
It was created to transform everything it touches into shit. If that isn't garbage then I don't know what is.

>>59735370
I'm trying to say that you can like complete garbage while still acknowledging the true nature of it. Which is something most POO fags don't seem to be capable of.

>>59734700

(defmacro min (val min)
  `(if (< ,val ,min)
       ,min
       ,val))

Works for me!

>>59735387
>Rust will never take off as a community
Where did he claim the opposite?

>>59735392
Nobody was saying it was the greatest thing in programming, or denying that it can be a pretty poor paradigm to write software in. You're the only one going on about it, so why'd you bother to post?

>>59735124
Don't do it: that way madness lies.

>>59735422
He said it was the future which implies that.

>>59735425
There is a large amount of "people" who disagree with the self evident claim "POO is complete garbage". That guy I was responding to seems to be one of them.

>>59735463
The only good OOP is CLOS.

>>59735256
>american education

>>59735474
>good POO
Such a thing is by definition impossible.
CLOS being closer to "original" POO and it being less garbage in general doesn't somehow negate its inherent flaws.

>>59735463
So you assumed the poster doesn't accept that oop is hit and miss because he replied to your shitpost and told you to fuck off?

>>59735502
you should start up an OOP hate thread. Let the grown ups talk about actual programming issues, take your flamewar elsewhere

>>59735503
It's not hit and miss, it's complete garbage. Which is something he refused to acknowledge.

>>59735502
Tell me, you've never had a good poo?

>>59735533
Why? POO is related to programming. Nowhere does the OP say something like "shit paradigms need not apply".

>>59734157
nth for FP will never displace OOP in industry and FP will always be a meme

>>59735580
No wonder a retard who can't use "meme" properly doesn't understand that FP isn't somehow the opposite of POO.

>>59735535
>REEE WHY DUZNT HE AGRE WIF MEEEEE

Jesus wept, do you really need that kind of validation? And again, this is just your opinion. Its not the best paradigm around but i doubt its the worst either. Nobody gives a shit if you don't like it, it's not going to stop anyone from using it, and endlessy screeching about how bad it is without actually offering any sort of alternative or serious criticsim other than "its garbage" make you worse than the fucking hasklel fags and the FP cucks.

>>59735110
If you're using an ORM like Entity Framework, translating the objects directly to serialized JSON results in an infinite loop if there are foreign key relationships.

In light of this, you have to create DTOs - rather than use your ORM models directly - to store the concept of the information that you want to produce in the API.

>>59735593
Jesus what is it with you people? Nobody said FP was the opposite of OOP. This board shills FP endlessly, thats why people target it when OOP discussions come up, usually because some FP tard chips in his 2 cents on how some functional language is the future and oop is dead

>>59735535
Why do you think anyone should validate your shitty opinions?

You're implying that anyone who "refused to acknowledge" that is wrong, without substantiating that which you think must be agreed with.

It's not. It's absolute truth and any non-subhuman acknowledges it.
>Its not the best paradigm around

>but i doubt its the worst either
Yes, you doubt it. Which doesn't change the truth in any way.
>Nobody gives a shit if you don't like it, it's not going to stop anyone from using it
I realize this. I didn't say that anyone should stop using it.

How is the existence or non-existence of such examples even slightly relevant? Or do you think for some reason that something being used more means it's somehow better?
Why do you think I'm a POO supporter? I've quite literally stated that I acknowledge the truth of it being garbage.

>>59735710
My opinion: I like OOP.
The truth: POO is absolute garbage.
These two things aren't mutually exclusive. I like it but I still fully acknowledge reality, which is a more than can be said about most POO fags.

>>59735763
>Ok so you dont see the board shilling OOP, wtf has that got to do with FP shilling?
FP is a subset of both POO and procedural programming. You didn't clarify which one you meant.

Way to shitpost. You keep banging on about how you recognise the flaws of OOP and accept them which others don't. Why? Why would that matter to anyone? Why would anyone care? you haven't changed minds, nobodys opinion has changed. Most if not all of your posts have been completely pointless

>>59730403
I don't quite see what you see as the problem with the bitmask still. If there's a really uncommon type and we defragment our slots well we can add a 'last instance of this component' index somewhere. Skipping the rest of the array. And even if we let it be fragmented we could easily design a structure that is aware of blank ranges.
>highly tweakable
Yeah. I love systems like this. There's too many systems around that just
>>59730270
Maybe the generation ID thing wasn't explained amazingly well. You just have an int that you increment and save with every newly created entity. So there's more information than just the slot identifying an entity. Could be any piece of information really as long as it's unique.

>>59735953

Makes no sense. This thread doesn't shill FP nearly as much as it does Rust. An imperative language.

But I'd say that FP and OOP are in closer competition, they're both currently poorly performing paradigms focused on programming convenience over anything else.

Really, POO programmers haven't even heard of procedural and/or imperative programming in a lot of these discussions.

No I was talking about mainstream OOP (usually imperative programming mixed with Object oriented design) vs Procedural FP.
But I should have been more specific. There's a massive amount of confusion about OOP and what it is so implicitly assuming we're talking about common industry trends is silly.

@59736180
>HURR DURR MAW I TOLDED THE BASTARDMAN TO GO TO REDDIT
Are you old enough to use this website?

>>59736026

I think you will end up with O(|E| + |V|).

For each node you have to test every other node, because "a is the shortest to b" does not imply "b is the shortest to a".
Also "a is NOT the shortest to b" does not imply "b is NOT the shortest to a".

You just can't rule things out easily..
Think about a graph which has the following "closest distances" (other connections not shown here):
O---O--O-O


But I'm not 100% sure about this one, so maybe someone has a real fancy idea here.

>>59736218
>@59736180
This look like twitter to you fuckwit?

>>59736143
It's often the case that OOP programmers here in /dpt/ haven't and the only paradigm they see other than OOP is FP because its mentioned a lot here. Rust is imperative. But it's usually not the case that we say that Rust is an imperative language.

So in short, OOP programmers here aren't experienced in different paradigms a lot of the time so they point at the only other thing they've heard about.

rly makes u think
(Floyd-Warshall takes V^3)

>>59736225

Oh wait, it's rather O(|E| * |V|).
You have to compare EVERY edge in EVERY vertex for the worst case - but only one time, since you can always save the closest distance.

But this is still kinda good (at least better than any all pairs shortest path algorithm).

Reality is often stranger than fiction.
Unreal engine 4 has macros to instantiate templated classes that do nothing but act as polymorphic types for doing render calls.
It's a mess to read but the api is at least ok. Terribly long names for the macros you use though. Probably beats them over the head with driver overhead too.

>>59736380
>code
Wrong thread. You're looking for /wdg/

>>59736276

It's pretty difficult to calculate. But I'm sure we can be better than Floyd-Warshall..


My reasoning is as follows:

1) Init: Each node has a List of all unvisited nodes.

2) For each node you save the current shortest node and distance.

3) We start at the node A.

4) When you check wether A->B is the newest shortest node, you can make two comparisons at once:
Is B closer to A than the current shortest node?
Is A closer to B than the current shortest node?
(This gives you O(2 * |E|), since you make two comparisons for each edge).

5) After the comparison you can delete A from B's list and B from A's list.


So if I'm not mistaken, it should be O(|V| * |E|) + maybe the intialization (unless we already saved it this way).

I was trying to prune the code but apparently it works differently depending on the way I put it. So, with the version I listed there, it seems to work. How ever, the original problem was this:

This code returns -16:

    e->x = 0
    pfi->w = 32

    short start_x = MIN((e->x - pfi->w / 2), 0);

But this code returns 0:

    e->x = 0
    pfi->w = 32

    short x = (e->x - pfi->w / 2);
    short start_x = MIN(x, 0);

I don't know whats going on to be honest.

>not having MinMax that returns a tuple containing both the maximum and the minimum

>>59739262
It's probably >>59738680, then. The second snippet works because you store the signed value of the expression. I'm guessing e->x and pfi-> are unsigned, so if you use it directly it's gonna be an unsigned comparison.

You should really call it MAX, by the way.

>>59739262
Anon enough trolling.
The problem is that you need double parenthesis before the ternary operator to group the expression and you've swapped the order after the ternary operator.

#define MIN(a,b) (((a)<(b))?(a):(b))

This min macro works.

I guess, my thinking was that I wanted to clamp a value to be same or greater as the compared value, but generally I guess MIN would mean getting the lower of two numbers.

>>59739505
>encapsulation is bad
what?

>>59739603
Read the next part of the sentence.

>>59739651
OOP is still OOP with just encapsulation. Encapsulation is good.

>>59739673
You don't seem to understand. Please reread the sentence.

>>59739556
Okay, let's look at the whole picture.

Assume programming paradigms are sets.
Assume FP is a subset of both OOP and PP.
Supposedly this means that the elements of programming paradigms are supported features. FP is a subset because it cuts out features that are undesirable for various reasons (purity, mostly).

Is this a useful definition? I don't think so. Paradigms aren't toolboxes, they're ways of thinking. FP involves ways of thinking that aren't present in OOP or PP at all (like making everything pure and treating code like something that can be passed around).

>>59739603
>>59739673
Writing invariants directly (with dynamically checked contracts, dependent types, etc.) is a lot better than maintaining them indirectly through getters and setters. Encapsulation also makes composition unwieldly, which is why inheritance exists, but inheritance sucks in its own ways. It also encourages making shared mutable state as it's easier to make encapsulated objects communicate by calling methods on each other rather than trying to write mediating code that has to live outside of the encapsulation bubble of each object.

Information hiding for the sake of API/ABI stability is also better done at the module/package level than at the type level. You want things in the same module/package to be able to depend on the implementation details of each other since they'll always be kept in sync.

I have no idea of what to do anymore. I know a few languages pretty well but I just can't get into a project anymore these days.

>>59739726
>Supposedly this means that the elements of programming paradigms are supported features.
Stopped reading right there. What a worthless post.

>>59739726
>FP involves ways of thinking that aren't present in OOP
This statement doesn't make any fucking sense unless you specify FP to mean procedural FP.
It's the equivalent of saying "Imperative programming involves ways of thinking that aren't present in procedural programming".

>>59739821
>This statement doesn't make any fucking sense unless you specify FP to mean procedural FP.
So you think "OO FP" is just OOP? Then "FP" should be the same as "procedural FP" and we're back at square one of the discussion.

>>59739726
>FP is a subset because it cuts out features
Please learn what a subset is before making such retarded statements.

Here are some members of PP:
C, Idris, H*skell
Here are some members of POO:
J*va, C*, *Caml, F*

>>59739850
>So you think "OO FP" is just OOP?
OO FP isn't "just OOP" in the same way imperative OOP isn't "just OOP". It doesn't make sense to say that something is "just OOP".
>Then "FP" should be the same as "procedural FP"
Not really. Procedural FP is procedural FP and FP is something which can be either procedural or OO. That's a pretty basic concept to grasp.

>>59739987
pls introduce context

>>59739988
I do. Not sure if I will share it with the likes of you though.

>>59739995
You think programming paradigms are sets of languages? That's even more useless.

If "OO FP" doesn't involve new ways of thinking compared to just OOP then what's the difference? It's just OOP that also has lambda expressions or something?

>>59740017
Arguments not presented might as well not exist.

>>59740046
>You think programming paradigms are sets of languages?
One can think of them as such. It certainly helped me arrive at a view of reality which is more valid than yours.
>That's even more useless.
It's a lot more useful than ill-defined and ambiguous buzzwords like "setting", "features", "way of thinking", "undesirable".

>If "OO FP" doesn't involve new ways of thinking compared to just OOP then what's the difference?
"OO FP" (as made obvious by the "OO") is not a member of the set "PP", meaning it's instant trash. That's the only difference I care about.
>It's just OOP that also has lambda expressions or something?
If it's based on any lambda calculus, then sure. Lambda expressions aren't the only requirement.

Good job.

Doing babby-level Cshart stuff, had a question about memory usage and how accurate the VS memory usage analysis is. I have a WPF program which is supposed to perform a sql query, fill a list with each row as an object composed of strings, write the results to an excel sheet, and finally use the outlook interop library to send a bunch of emails based on the rows. It does what it's supposed to do so far, but the program uses ~70mb while idle and 90 while sending things out - after sending emails out once, it sits around ~90mb usage as a new idle high.

I've been using things that can utilize IDisposable and nulling references to objects after they've been used, but those numbers haven't really changed, but maybe I'm missing something? Are the numbers that VS displays about memory usage for a program accurate? Am I just too new and not in the loo?

If I were to be building an engine from scratch, and I wanted to be able to repurpose it in other applications, the smart way to write it would be having a "driver" application/class that imports it and makes the calls from there for testing and development, yes?

working on ending my life

i'm 24, learned everything i know about software engineering from my job, reading books, and working on projects

i'm being paid $22/hour as a software engineer for a small startup that hasn't made any money since it was created a year ago. i have less than a year of experience, so i don't see myself getting a better job somewhere else anytime soon, and by that time the company i work for will probably have gone under so i'll be even more unhirable.

i'm also working on a concurrent flood fill maze solver.

programmers are cancer
you should all die in a death full of pain

>>59740273
VS is reasonably accurate when measuring memory usage, but C# is also a very memory hungry language. Depends on exactly what you're calling where, and how, you could be implementing a lot of high-memory structures or leaving a lot of data floating around in lists that weren't cleared out.

As long as you're not inflating over 90mb on sequential runs of the program then you're not leaking anything, which is the important part.

A year of experience as a developer goes a long ways. $22/hr also isn't that bad depending on where you live, and especially considering you got the job without academic credentials.
I'd ride out the company and maybe even ask about a raise. Otherwise just start poking at job listings and other companies and see who'll give you the time of day.

>>59740547
Are you properly clearing the list at any point? Lists are really generic and take up a lot of memory compared to more specific structures, who knows what C# is deciding to implement.

Be glad you have a job. There are plenty of CS graduates who don't have much experience and struggle to find work. $22/hour isn't a ton, but it should be able to float you by until you find a better job. Since your already have experience, finding new jobs should become easier, even if your company goes under. Remember, your job is to build the product, not to sell it.

The same company covered my bonus i would lose out on in my old job if i switched(15k), a signing on bonus(4k), a guarenteed pay raise in 6 months(10% of gross salary) then again in another 6 months(another 10% of gross salary), and 12-14 weeks training in what they do and the various tools and technologies they use, with an extra 12 weeks training afterwards if i still didnt get it.

UK attitudes towards blacks is surpisingly warmer than the US. Pajeets get shit on almost everywhere here, Other races depends on where you move to

Yes, thank you, i fixed it by doing this.

def load_reg():
    global register_file
    global register
    if os.path.exists("accreg.dat"):
        print("Debug[1] Reg File Found")
        register_file = open("accreg.dat","r+")
        print("Debug[2] File assigned to register_file")
        register = dict(register_file)
        print("Debug[3] Created register reference")
    else:
        print("Debug[1] Register File Not Found")
        register_file = open("accreg.dat","w")
        print("Debug[2] File created & assigned to register_file")
        load_reg()

But i'm not black either, to be fair i met quite a bunch of people from the UK on my trip to Japan last year and they were all a cool bunch compared to Americans and Chinese who were unpolite and loud

I'm just concerned about dem ragheads going nuts over there on the UK, i come from a country with strong christian values and muslims are pretty much non existent over here

There has been what, 1 attack with multiple casualties in the past 20 years? I would be more concerned about Catholic terrorists in the UK, the Irish have a much longer and much bloodier history of terrorism in the UK.

How to store application configuration between sessions?

System registry?
Config file?
You can probably store it in the executable file, although i'm not sure how to do that and it seems like a bad idea.
Any other strategy i haven't thought of?

>>59741361
if you need your application to be stateless just offload configs into something like etcd, consul, or another key-value store. you could also use something like redis or mongo to store session information.

>>59741393
To heavyweight for my needs. Thanks though.

what the fuck is wrong with this shit
the literal accreg.dat file says:

{"Dan": [1500]}

just that, but when python tries to make this a dict this happen.

  File "fiaton3.py", line 24, in load_reg
    register = dict(register_file)
ValueError: dictionary update sequence element #0 has length 15; 2 is required
