I feel like I am not autistic enough to be a good programmer.
Is it possible to acquire autism somehow?

i studied anthro as an undergrad and it wasn't too hard. you need to develop an intuition for the thing each problem is presenting, but it starts out trivially easy and ramps up at a reasonable pace.

if you can't do it, calling yourself "not math inclined" would be an understatement.

What am I doing wrong?

>>59914847
Not programming related.

>>59914847
in my case, yeah. i studied digitally mediated cultures and got into one of the top ~10 CS PhD programs to do more of the same, and i'm really happy.

it very much feels like one of those things that if i tried to do again an atom somewhere in the universe would be in the wrong position and it would all unfold differently, though. so i strongly discourage people from trying to do exactly what i did.

>>59914869
Ha, don't worry, humanities are really not my thing, and I have no desire to go back to school again. I was just interested because anthro + CS seems like such an odd combination.

>>59914879
it's definitely weird and unusual. i had to show that i could hack it (not in the "lulz hacker" sense but in the "keep your head above water" sense) in a CS program, but i did that and it worked out.

my glib explanation to people is that CS has room (read: enough funding) to accommodate weird people like me who don't fit many existing molds. anthro, sociology, etc... don't really have a ton of funding for people who are weird and don't conform to their existing sense of what a good anthropologist is/does, so there's only a certain amount of latitude for people to do interdisciplinary stuff (e.g. interviewing (which is anthro) and system design/building (which is obviously CS))

Anybody know why my encrypt/decrypt is getting fucked up; I'm using curl and I'm just practicing out load balacing with php and apache. I know it needs to be encrypted but I was having a huge problem with openssl_encrypt().

I went so low as to switch to using a hard coded key; and then to simplify it I even went down to base64 (just to see if really was something other than the AES key/iv.)

No matter what I do I always get encrypted text back, it simply will not decrypt and I'm at my wits end (but need this problem solves :( .)

How does that negate the inherent redditry in saying "lulz hacker"?

>>59915086
I think you're missing an extra _ on your inits
try __init__ instead of _init_

>>59915181
as in i'm specifically saying i'm not talking about "hack it" in that context. the fact that i'm aware of language (which happens to predate reddit by kind of a long time, frankly) doesn't mean that i spend time there or subscribe to "redditry". it literally just means that i'm aware of the other connotation.

Legitimate question from someone who's in his second semester for compeng: is it worth learning C? My beginner compsci classes about syntax and basic bitch algorithms were all in C++, and my class next semester on OOP is using Java. However I want to make some software over the summer that isn't just command line calculators or programming challenges and apparently C is good at preparing you for that. Is there any big syntax differences between C and C++?

>>59915235
>is it worth learning C
Yes.
If you started on C++ then learning C will take you all of 15 minutes, and it's good practice to deal with pointers and memory allocation more forcefully.

>>59915235
>OOP
Go be retarded somewhere else, like at reddit.

>>59915255
not him, but if i started with C# how hard would it be to learn C++?

FFS, anonTurd!
the kid can't help that they make him take OOP as one of the classes in the degree program

>>59915273
It would take you much much longer, because C# is not based on C++ in the same way C++ is based on C.
It still wouldn't be a herculean task or anything, probably a week to get the syntax down and another week to cozy up to not having the CRE fix everything for you

>>59915296
i see, ty

int a = new int;
free(&a);

>>59915295
They can't really make him do that.

>>59915358
Do you know what degree requirements are?

>>59915273
They're different languages entirely, you wouldn't find most things you learned in C# useful in learning C++. Some basic syntax, maybe.

What are some programing projects that I could work on to make me a better candidate for entry level Networking jobs?

>>59915402
Yes. I don't see how anyone can force him to learn OOP without breaking some laws.

>>59915273
speaking from experience, it helps. but that doesn't mean it'll be easy, per se. take away the garbage collector and reference types and they bear a lot of similarity (especially unsafe C#). hell, they're even interoperable to a degree with C++/CLI. but no matter what you're coming from, C++ is a bit of a rabbit hole, to say the least (especially if you keep up with the new standards, which you should). it shouldn't take long to get comfortable with basic shit, but expect to periodically discover weird little edge cases and idiosyncrasies for months or years to come

Does your program work with the trivial cases?

I want to create a text editor in n-curses, but I have a dumb question, would it be possible to dynamically create LaTeX-like formatting?

Like, when you finish typing

\lambda

or

 \frac{\partial u}{\partial t}

, it appears as a single character (as it would normally appear in a compiled TeX document), much like what Word does, but better.

What would some good books/resources be for this project?

Good evening, /g/

Allow me to provide some background on what I'm working on. I am building my first large personal project. It's largely abstract at this point, but as i figure out databasing basics with sqlite, I'm getting to the first steps in actually constructing the fundamental c# classes I'm going to need.

For lack of a better word, i need to store a bunch of 'scenes', where each scene is just a specific instantiation of a certain class with different parameters set in different ways that sort of define each version of this object as 'scene1', 'scene2', etc...

How do i go about storing these scenes in the final project? I'm already using sqlite for another part of the program, so using that should be no problem.

Do I just store a set of parameters? And then somehow 'feed' that into the creation of these objects? What's The design philosophy around this problem?

The only remotely intelligent thing you have said.

About that embarrassing second paragraph, it would be best if you deleted your post to remove it.

I'm trying to read data form data segment but I get a segmentation fault. AFAIK everything is readable and addresses from _etext onwards should belong to my process

void read_data(uint32_t *start, uint32_t *end)
{
    for (; start < end; ++start) {
        uint32_t v = *start; //segmentation fault here
    }
}

int main(void)
{
    extern uint32_t _etext, _edata; //man 3 end
    read_data(&_etext, &_edata);
}

If you're declaring external symbols, you shouldn't put them in a function definition. That's just bad form... or at least incredibly uncommon. Also, man 3 end for me suggests that the names of those symbols might not begin with an underscore.

That all aside, you are trying to read every address starting with the beginning of your .text section and ending with the beginning of your initialized data section, you might just have a problem. Your OS doesn't need to make your initialized data section start immediately after your .text section, so some of the pages between the two may be invalid.

>>59916959

.NET isn't necessarily web related.

&_etext points to the *end* of text segment. Right after that should start data segment. If not, however, then these values are garbage and I don't understand why they're provided if may point to invalid data.

>>59917021
I'm reading from the end of text to the end of data. Not from the beginning of text to the end of data.

>The library doesn't know how many global and static variables the user has defined and afaik going through the data segment is the only way to find out
Scanning the data segment is not gonna tell you how many global variables there are.
How could you tell the difference between say an array of bytes or N seperate integers that happens to be contiguous?
And if you have some kind of memory map to compare to, why do you need the scan?

>give up on the possibility that it contains anything that I don't already know; if it does, there's undoubtedly a place to learn about it that doesn't involve drudging through a pile of shit in order to find it

The people who write these things need to be grilled over their use of space fillers that exist solely so that they can take a topic that should take maybe 300 pages to cover and drag it out to 1000+ pages so that they can murder your checking account without raising eyebrows. I have no doubt whatsoever that this is what's going on.

Good online tutorials are a fraction of the length of this textbook, cover more topics in a more concise and articulate manner, and their cost is often however much you pay to access the internet.

Looking ahead a bit, I know that it might seem inconceivable in the current environment, but much like any human institution, the survival of universities is not assured. There's already a lot of worry and debate spread around society about the cost of going to university. They don't need to add quality concerns on top of that. If they can drop the cost of textbooks and increase the quality instead of lowering the quality in order to increase the cost to students, that could be a significant contributor to the state of universities in 2037.

/dpt/ why do people use hash tables tries are clearly superior

tries:
* lookup time is linear in key size in the worst case, with a high overhead but no other independent variables
* easy to understand, work with, and maintain
* no wasted space but high spatial overhead

hash tables:
* high wasted space -- still much less space lost to waste than tries lose to overhead, but who gives a shit, it's 2017
* easy to understand and work with, pain in the ass to maintain
* CLAIMS to boast constant lookup time, but ACTUALLY, lookup time is linear in table size in the worst case, with a high worst-case overhead, AND it's ALWAYS at least linear in the key size, because any hash function worth using must process the entire datum

Not really, it's dynamic garbage which means it should be banned and outlawed.

>>59917668
Let me tell you about Common Lisp.
The base language is really verbose. This is my opinion but having read a lot of lisp I still think that loop constructs and recursion in Lisp is harder to read than eqvivalent C or ML code.
The cool thing about is macros and especially readermacros but you won't use them. You would need to allocate some kind of string for readermacro starter which makes your API usually more complex.
There is no good lisp implementation for deployment. You either need to add the whole lisp environment in to the application making even hello word size to about 50mb. Give people compiled fasl files which are not portable between different compilers and not even portable between versions in same compiler. It would require the user to install lisp environment. There are Common Lisp compilers that compile to C but they are either not maintained or really buggy.
There usually is no libraries in Lisp that would help you for the task that you want to implement.

Anyone use Go? Thoughts?

I know how to do that, but I won't help you since you posted this "man".

Yes. It's garbage.

Can you explain why data segment doesn't start right after text segment? I can't understand the design choice behind that

i implore you to try another approach than OOP, especially c# OOP. You will write 10x more code than is required for no gain, refactoring will be a monumental task

So learning lisp for academic purposes is not valuable?
I think it's good idea to learn/understand how different languages work.
Keeps mind sharp.

i made this thing to help me find anime movies i haven't watched yet instead of having to go through a bunch of bullshit top 10 pages

>>59918377
>So learning lisp for academic purposes is not valuable?
Not really, any statically typed language similar to it is already better, and a lot of those are outright garbage.

>>59918387
You don't belong here if you haven't watched most of these.

>>59918387
Source code?

>>59918414
kimi no nawa doesn't have legit subs and koe no katachi doesn't have a bd release, i haven't watched mushishi and kizumono 3 doesn't have any online release either

but that was just an example

>>59918397
You are ignorant. Nothing does homoiconicity as well as Lisps.

>>59918397
Can you elaborate on your research why it's not valuable in any way?

>>59918477
Lisp's homoiconicity is a fundamental design flag.
>>59918486
It is actually valuable if you want to learn just how shit a language can actually be.

>>59918513
Tell me about your experience with lisp.
I want to understand how much your opinion is valuable.

>>59918533
I haven't stated a single opinion so your request is impossible to fulfill.

>>59918536
Then give me source of your facts like
>Lisp is garbage

>>59918554
That wouldn't fall under the definition of "fact".
And I didn't say it was garbage, I said it was "dynamic garbage" and a "shit language".

>>59918414
I've watched a crapload of animu (~400 series), but I've seen less than half of those.

>>59918576
Then what are these statements if not facts nor your opinion?
You just type random letters?

>>59918595
>Then what are these statements if not facts nor your opinion?
These statements are true under all possible interpretations and regardless of anything else.
>You just type random letters?
I don't think typing random letters could possibly construct these kinds of sentences in any reasonable amount of time.

From this very general

>>59918617
So you just assume this is true without any common ground on these statements?
Just out of the blue
>Lisp is shit language

Wow... I wish I would get hallucinations like this.

>Stating something obvious without trying to interpetate what it could mean

Know I know that your opinion means nothing, thanks.

>>59918670
>So you just assume this is true
No.
>without any common ground on these statements?
What is that even supposed to mean?
>Wow... I wish I would get hallucinations like this.
It's merely a simple and self-evident truth.

>Stating something obvious without trying to interpetate what it could mean
I literally could not comprehend what you were trying to say here.
>Know I know that your opinion means nothing, thanks.
I haven't stated a single opinion anywhere in my posts.

So what's the drill If I really like a language and I want to learn it properly, let's say Rust or Scala ( random examples ) - could I find a job for it even if it implies traveling?

Or should I mainly research job opportunities around my region / region I desire to work in.

>>59918710
>Rust
CIA garbage with a weak type system.
>Scala
Possibly CIA garbage with a weak type system.

>>59918710
If you want a job, pick a language from the top of this list: https://stackoverflow.com/insights/survey/2017#most-popular-technologies.

Anyone can recommend few books on C alongside the K&R2 - that discuss modern implementations and solutions and cover C11?

There's so much C maculature and I'm still a novice programmer If I get the wrong book I might develop bad principles and practices.

>>59918742
I've picked C++, C and Assembly to learn this year - hope it will get me one, C++ is a language I'm genuinely obsessed with.

Assembly would take me probably 3 years to program good commercial stuff with, but at least in one year I'll be competent with it.

>>59918750
>C++
Go be retarded somewhere else, like at plebbit.

>>59918757
Oh sorry I meant Java :^)

>>59918750
Java and C# are more popular, but there are plenty of companies hiring C/C++ developers. Mainly those who work with embedded systems.
I highly doubt Rust will get you a job anytime soon. The language is too young and it doesn't offer any significant benefit over C++.

Surely a security feature to avoid reading data as if it was executable, tell you what. Is the text_end thing or whatever page aligned btw?
