Wikipedia code base is in PHP/MYSQL as well and to be honest from a developer point of view being able to handle only 50 000 requests /s with 200 servers is just pathetic. (Source: https://meta.wikimedia.org/wiki/Wikimedia_servers)

As for 4chan, using webp for every images could reduce all bandwidth for at least 30%. Also, if this leak (https://gist.github.com/dvliman/11264471) is real, the servers are basically wasted at this point.

Despite everything, 4chan and Wikipedia are both the best website on the internet though

Apply anyways. Call any side projects you've had experience.

Does anyone use fonts with ligatures for programming?

Employers market, they can afford to be picky.
And if you're not a good pick, they have 50 other interviewers that day that might be a good hire.

The "programmer shortage" was a lie invented by colleges to flood the software industry with low quality "coders" and effectively turn SE into the janitorial work of the 21st century.

chuu~:3

Right now I am living in Germany, speak English and German. I have learned C, the Linux and Windows API, a bit of C++, a bit of x86 assembly, a bit of C# and a tiny bit of Java.

The last two years I have spent programming my own framework in C that is supposed to solve some of the more retarded bullshit that Linux and Windows incorporate. That includes my own memory interface that works without userspace locks, an ISO9660 loader, an HTTP stack, a generic array structure, an INI parser and a 4chan API module as well as a kernel thread abstraction layer (no user threads as I fail to see the point in those) and a SOCKS connector. Right now I am also working on a way to access timezone information on both Windows and Linux.

The problem is: I have no mathematical background. I don't care for maths; it's outright boring to me, I tried to learn it and failed.

I don't even dare applying for jobs because I think the interviewers are going to tell me outright that I don't have what it's gonna take for me to work for them. Also I prefer to program slowly, but properly - in other words, I am not really productive.

If you would see this CV, would any of you consider hiring me? Should I generally develop more confidence?

>>57138587
>all cancerous shit
Sorry but this is Java. You can still delete you "reusable" program and start over in C though (._. )

>>57138621
In all seriousness no memes, I'm not that deep into learning java. Should i just switch to C?

Don't think so buddy.

>>57138618
I learned German for 1.5 years and "deutsche sprache, schwere sprache." I'd recommend becoming a little more comfortable but you should never stay in your comfort zone for too long.

Also, your English is amazing, even though you being a German will say it is not ;).

>>57138631
To be honest when someone say Java or PHP I laugh nonchalantly.
C is a great language, I don't like C++ but it's useful. Python is most likely what you should learn.

It's easy to learn so 'tards and normies use it everywhere for everything thus creating a market for it.

And how am I supposed to do that? As I said I am lacking confidence to even try to apply for a programming job because they all seem to be so high level that I'd just make a fool out of myself there. As I said, I have no math background, I don't like it at all.

When I am lacking that initial confidence, how am I supposed to stand against all those graduates who are supposed to have learned that stuff for several years?

Education is for retards unable to think by themselves. What's the problem?

hey /dpt/, i need a project to work on for the job hunt. any ideas?

I'm kind of lost on where to go. I've been using Python for a couple years and written some medium sized projects but they're nothing amazing and my utilization of OOP is shit. Stuff I've written and then looked up on Github is implemented so much better than my projects.

It's also not my job and sometimes it's hard to keep working on projects. I feel like a job environment could be really conducive to speeding up my learning but I'm a NEET and the thought of getting an office job makes me panic.

>>57138778

It's standard bullshit HR people put up.
I know of a local web dev who put up 5+ year experience of stuff like Gulp and Angular yet hire anyone who knows of CSS and has even glanced at javascript.
As long as you have projects you've done outside of college you're fairly well off and can get a job at the majority of places..

If you want to work for Microsoft/Facebook/Google/whatever then get Cracking the Code Interview and treat doing every algorithm excercise in it like a job until you can do them on a whiteboard in sub-10 minutes without any problem. (they use it for weeding like others do fizzbuzz)

>>57138324
It's only really an employer's market in places like Silicon Valley or Seattle. In the vast majority of places they hire anyone with any coding experience whatsoever and basic communication skills. If you get fired you're going to have a job in less than two weeks afterwards as well.
They HR people adopt the same phrases into their descriptions as the tech hubs but it's perfectly fine to treat it like the most basic of guidelines. ("Oh, they want 5+ years of C++ experience? Well my 1 year of intensive C should do fine, it'll compile.")

>>57138618
>If you would see this CV, would any of you consider hiring me?
Pretty much any place would. That's really damn impressive.
> because I think the interviewers are going to tell me outright that I don't have what it's gonna take for me to work for them.
If so it won't have anything to do with your programming skills and it'll come in the mail afterwards as "Thank you for participating the position has ben fillled." rather than something embarrasing. Any programming job will have a shitton of people applying who can barely program or have a much less impressive and smaller portfolio than yours.
>Should I generally develop more confidence?
Yes, definitely. Your math worries are pretty much unfounded. Only like Quant finance-people are required to have a moderately strong math background.

>how am I supposed to stand against all those graduates who are supposed to have learned that stuff for several years?
I am a graduate in like four months. My portfolio is thin, the most important thing i've picked up from my Bachelors is basic algorithm design that anyone could get from books and i've already forgotten 70% of the math i've been forced my way through. Despite that i'm better than the average CS student and have no real worries about getting hired.
TLDR: You've got nothing to worry about.

>>57138903

>>57138931
The only easier way to put it would be to spoonfeed you the definitions of words you don't understand.

>>57138903
>Pretty much any place would. That's really damn impressive.
Why do you think it's impressive? All I ever did was reading documents and implementing stuff right away, then after a while realizing what I did wrong and fixed that.

>Yes, definitely. Your math worries are pretty much unfounded.
As I said before, in forums in which more successful people post I always feel as if I am the retard because I just don't understand higher math, and they make it pretty clear that higher math is required universally. Also, don't forget that I am living in Germany, so software requirements may be different from the ones in the states.

>Why do you think it's impressive?
First that your portfolio exists at all. You have no idea how much worse a lot of applicants are.
Secondly that it shows a relatively deep understanding of memory, the Linux and Windows APIs and intermediate networking.
>As I said before, in forums in which more successful people post
In other words very experienced people who've been in the business a longass time and are discussing positions way above you or far more likely people who lie on the internet.
>and they make it pretty clear that higher math is required universally.
They're absolutely full of shit. Higher maths isn't required at all outside of very specific subsets of the industry such as quantitative analysts for high frequency trading. Even realtime system graphics people will admit their jobs don't require a significant amount of math.
It sounds like you've been listening to academics and not people who actually write code for a living.
>Also, don't forget that I am living in Germany, so software requirements may be different from the ones in the states.
Germany's software requirements aren't significantly different from the rest of Europe, I merely used American places of reference because that's where the HR people are getting the retarded idea of putting up higher and higher reqs for junior positions even when a fresh-off-the-boat patterns-pajeet or Javascript-jobber would get the job.

Your problem is that you are using sizeof on a pointer, not an array. Array-to-pointer decay, you want to google that.

>>57139526
it's size of the type of the array (char *) / sizeof the type dereferenced by arr[0], which is char

>>57139533
What array? "str" is not an array, it's a pointer. An array knows its length, a pointer does not. A pointer has no concept of length. When you ask sizeof to query its length you'll get the size of the pointer - 4 byte on 32 bit processes and 8 byte on 64 bit processes.

IMO all languages have conventions that are used more often in that given language, in that example I find it okay since it's C. And I wouldn't use braceless if statements in C#.
Another example: People in Ruby like to use 4 spaces in identation.

>>57139561
No, it's not fine!

#include <stdio.h>

int main()
{
    static const char array[] = "COMFY";
    static const char*const ptr = array;

    printf("%lu|%lu\n",sizeof(array),sizeof(ptr));
    return 0;
}

Are you trolling or what?

I don't like excluding braces. Yes, excess braces is horrid but I rather make it clear rather than have someone second guess the indentation is wrong and code is executed out of scope.

Who cares if it compiles with that? It's still wrong. It only will not be wrong if by any chance the length of the data within the array is the same as the amount of bytes a pointer is reserved for.

Hey /g/, beginner here, currently studying data structures. I was thinking about doing a program/project that creates simples shapes in an animation

But I'm scared of doing more like an animation project than a programming one.

What can be the "programming part" of a shape creator?
Randomize shapes, have some type of algorithm to create a shape, something of the sort?

I might as well ask for anyone willing to answer, is there an specific type of projects that employers look for and this might not be a good one to grab someone's attention?

You don't get to say what is and isn't C. We have a standards committee and standardization process because the language isn't headed nor is supposed to be headed by a benevolent dictator.

If you don't want to use the latest standard of C, that is YOUR choice, not the standard everyone follows.

>>57139751

>>57139853
>If you don't want to use the latest standard of C, that is YOUR choice,
Actually, NO, because there simply might not be compilers available for the system. If I can't compile it on a C89/C90 compiler (which are the mostly available ones), then the code is just a piece of shit. The program is then coded in shit. Not in C, but in shit.

begin
   Put_Line(Integer'Image(String1'First)); -- 1
   Put_Line(Integer'Image(String2'First)); -- 2
end Test;

You can see when copying the String the indices stay the same (we copied indices 2 .. 3 so String2 has indices 2 .. 3)

>>57139892
and yes

for I in Text1'Range loop

is a simpler way of doing

for I in Text1'First .. Text1'Last loop

>>57139883

That's the system and its ecosystem's problem, not the code's problem.

You know how long it took for Microsoft to even try and support C99? Near close to 14 years after it was published. Did anyone blame C99 for that? No, Microsoft was being a piece of shit and people simply either dealt with it or didn't.

>>57139687

Right, but C11 is the current standard of the C programming language, so it is perfectly acceptable to mix declarations and code as much as one wants.

top kek. much more than sufficient. i've worked SDET contracts at Microsoft and i didn't even graduate high school (not that they asked). it was uncomfortable when people were impressed by basic shit. it was like they'd only ever used C# for writing unit tests and automations of a specific sort and didn't realize that it's a programming language and you can do literally fucking anything you want with it. i was basically a self-educated half-retarded kid when i was there and i was coming up with and doing shit my leads or other full-timers surely should have done long before. of course i had to learn how to break those things the right way or i'd get pushback because they didn't want to look bad for not doing it themselves/earlier. some fuckin culture they've got going there, great for the business i'm sure. anyway except in a couple specific places, most of the SDETs and even devs there are surprisingly bad. maybe i was naive but i expected better going in. the bar isn't that high is what i'm saying

>>57140473
Neither. Even if we are assuming no optimizations whatsoever, it takes the same amount of time to load the immediate 1 into a register as it does 2, on every instruction set architecture worth discussing. The rest is going to be a comparison to 0 and a conditional jump, regardless of the immediate. In optimized code, this is just an unconditional jump.

What runs faster
x = x + 1
Or

>>57140575

Actually, no. O(1) implies constant time, because there is always going to be some constant that you can multiply by 1 to get the actual amount of instructions used, O(0), however, implies no time expended whatsoever. An algorithm can only ever be in O(0) if it is never run.

Well does it just work or not?

It just works.
And in case you fuck up, you get proper warnings.

>>57141104
Oh I get it. The wording confused me.

>>57140926
errno is an artefact from hell. Just let your functions return error codes directly, and save your actual results in pointers - or, in your case, a pointer to a pointer.

Also be aware of your critical path:

int format_context(AVFormatContext*ctx)
{   
    int my_errno;
    
    if(0 != (my_errno = avformat_open_input(&ctx,NULL,NULL,NULL)))
        goto LABEL_ERROR;

    if(0 != (my_errno = avformat_find_stream_info(ctx,NULL)))
        goto LABEL_ERROR;

    my_errno = 0;
LABEL_ERROR:
    return my_errno;
}

>>57141113
Yeah, sorry. The post was bad and I should feel bad.

>>57141126
Errno, varargs and unions are the bane of every binding writers existence.

>>57141126
>>57141164
I use errno here >>57140953 because it integrates nicely with the binder language's(Go) error handling. Should I just declare a pointer on the Go side and have C allocate it?

>>57141126
There is literally nothing wrong with errno.

>>57141189
You want to read the man page for strftime.

>>57141173
>Go
If errno maps well to Go, I see nothing wrong with it.
It's always been a royal pain in the ass for C#, Ada and Haskell which are the only languages I wrote bindings to C in.

I'm not sure about that allocation.
Who cleans that up?
Maybe you should hook it up to Go's GC.

>>57141189
In glibc it's not even a fucking variable.
It's a goddamn macro.

>>57141209
>It's a goddamn macro.
What of it?

>>57141209
It's a macro to a function call which accesses a variable that is stored on TLS. Which means that it's unique to each kernel thread.

>>57141002
>I want to take pride in my work, so I'm going to try and do my job as best I can
i hear you. i'm the same way. i was never a huge fan of microsoft, generally, but i still took my work seriously while i was there. the amount of political bullshit was really disappointing, though. people will get paranoid about getting culled and they'll throw someone under the bus to cover their own ass. obviously not everybody is like that, i knew some really fucking cool people there. but to be sure, some pretty shitty people have worked their way into pretty safe positions by resorting to such tactics. but i guess that's probably the case with any company that size

>Then why seek an internship at all?
it looks good to employers. interning is just a proactive thing to do because it adds to your education and shows initiative and shit, but it shouldn't and doesn't mean that's the company you've already decided you want to work at for your career. most interns get the offer to come back full time, but certainly not all of them do. the ones that don't either didn't necessarily want to work there full time to begin with, or they decided they definitely didn't want to during the internship, kek

>>57141209
Can't hook it into Go's GC, but manually deallocation is trivial with a defer statement. If passing a pointer is a better practice, I can easily switch to that.

>>57141215
>>57141213
Sure, there are good reasons for it to be a macro.
But you cannot just link against errno from some other language. And that sucks.

Also it's just deceiving. If it is a function, it should look like a function, not like a global variable.
I know backwards comparability blabla.
But I just don't like it.

>>57141251
That's why I say: always return error codes directly. Don't do bullshit like checking for a specific error value and THEN reading the fucking error code - instead return the error code directly.

>>57141247
>trivial with a defer statement
That's not really the point though.
If using defer for something like that is idiomatic Go, then do it.
I have no Go experience, so I don't know.
But a good binding should feel like it was written in the target language.

>>57141251
>>But you cannot just link against errno from some other language.
But you can.

>>57141317
Tell me how I can link against a macro.
I could link against the __error function the macro expands to, sure.
But that's really not what I want.
It's not portable, because some other POSIX implementation might do something else.

>>57141338
>It's not portable
It's not like the piece of shit language you're using is portable lmao.
>oh no, how dare other languages use features that my language doesn't even know exists

>>57141367
Usually C works with everything. That's why it's still used everywhere - because it runs everywhere, and the interfaces usually are also well documented.

>>57141338
And once you have errno what do you do with it?

>>57141398
That depends on what you actually want to do.

Some function calls return an error code that is non-fatal - take recv() on non-blocking sockets for example. That function might return a EAGAIN if there is no data available on the socket, but the socket has not yet timeouted or has been closed. In such a case you rather want to call select/epoll to wait for data to be sent to the socket rather than just freeing all resources that you have reserved so far and just failing like a prick.

>>57141444
>That function might return a EAGAIN if there is no data available on the socket
How would you know what it has returned?

>>57141367
You can use any C feature you want inside your code, I don't care.
But you should design your library interfaces in ways that are easy to link and bind to.
That means no errno, no varargs and no unions in user facing prototypes.
Which is good C style anyways.
(You can have *additional* vararg variants of printf-style functions to make C programmers lives easier)

C is not the only language in the world.

>It's not like the piece of shit language you're using is portable lmao.
Now you are just shitposting.
I have that portability problem already when I want to run the same code on Linux and BSD.
And virtually any language can do that.

>>57141398
>And once you have errno what do you do with it?
I read it, duh.
But what I do next depends on the target language.

If the language has exceptions and exceptions are widely used, then I translate errno
into the appropriate exception type and throw that.
If exception are not available or not appropriate I return it as a normal return value or as an out parameter (again, depends on the specifics).
I just try my best to translate that errno mess into the target languages preferred way of error handling.

>>57141457
>If the language has exceptions and exceptions are widely used, then I translate errno
>into the appropriate exception type and throw that.
How would you know which one is appropriate?

>>57141448
Sorry, I phrased this incorrectly. recv() will not return an error code, but rather -1, and set errno to EAGAIN.

Don't get me wrong, I see the point why someone would like to read errno there.

>>57141457
>C is not the only language in the world.
I sure hope all of your language's features are easily usable from all other languages. Otherwise you'd be a major hypocrite.

>>57141476
You obviously don't get it. errno is a macro. EAGAIN is also a macro. If you can't access the one, then you can't access the other either.

>>57141497
EAGAIN has a value that can easily be retrieved.

A new policy at work is for all software requirements to go into an HP product called HP Application Lifecycle Management (ALM). The business analysts spend all their time typing up stuff in ALM. However, as part of our "least privileges" security policy, developers don't have access to ALM. Never underestimate the stupidity and incompetence of large organizations. They are literally hiring people to write documents that nobody will ever read. Then management sits around scratching their heads, wondering why developers don't know the requirements.

>>57141512
The address of errno can easily be retrieved.

>>57141514
Those are diversity jobs.
be thankful they're not stuffing token hires in your department.

>>57141519
How? For EAGAIN I open the definition, or just use this:

http://www.virtsync.com/c-error-codes-include-errno

And there we have the code. Getting errno is a little harder because it's a thread-local variable.

>>57141533
>How?
By opening the definition.
>And there we have the code.
Not portable.

>>57141463
I define exception types for all values of errno that can occur plus a "catch all others" one.
It's a huge pain in the but.
No it's questionable whether something like EAGAIN should be an exception.
It really depends on the API in question and how the target language usually deals with errors.

>>57141480
For library code, that I expect to be used by other languages,
I export a easy to bind C compatible API.
If my language can't do that directly, then I have to write a C wrapper that does it.
Kinda like libzmq handles it.

>>57141497> EAGAIN is also a macro
You write a small C file that exports it's value a a linkable int.
