Yeah anon, you sure got me there with your inductive logic programming, if only I could "into unicode" as much as you could. I get what you're saying, Java IS shit in that they perfectly overlap and as a consequence anything that is not Java cannot be shit, yes. While your formal logic is spot on, your informal fallacies are off the charts as the many anons have tried to underline.
I recommend you get in a squatting position then rapidly snap into an upright position. That popping sound you will hear is the sound of your head being dislodged from your cavernous asshole.

Eh, maybe that's not quite the right way to go about saying this.

Types are a useful mechanism for reasoning about code, and internalizing them in the language lets the compiler act as a proof assistant.

I can't rage enough at the autists who decide to, in proffessional long term products even to make thousands of files and put literally god damn everything in classes no matter what it is. They have absolutely no idea of what a virtual table pointer is yet still get amazed when a memcpy crashes and act as if everything that happens on the assembly level is 'just magic' and that makes my blood boil.

Modern C++ programmers act like they want it to be Java or C# instead but still talk shit about those languages because '''its not as good as C++'''.

>>55947674
I could have been more explicit. I just received some bullshit app written in python 2.4 with some quirky versions of some libraries. Luckily, all of that is hidden in an virtual-env. This month we were working on another bullshit python app that ran on 3.3 with some other shit. Sadly, it required odd versions of ubuntu packages for compatibility reasons so just chucking the python shit into a venv wasn't gonna cut it, the packages would bleed out system-wide so the team-lead and the autism squad experimented with linux containers. And here we are now where we had to choose between containing our projects with Vagrant or Docker. Docker had the added benefit that your contained dev space is also a valid 2-command deploy image. Our workflow is that every member of the team has 2-3 of these projects runnable on their dev machine and as such you can't crap it up (and after wipe it) with whatever bullshit packages the next app needs.

I am new to C.

I made a code that read a formated .txt and store strings in an array of strings (char *array[16])

I'm not sure but the 16 in this is the size of the array as in it's the number of variable, right ?
I'm allocating 1024k for every strings (they're description) so char *array[16] is the same as char array[16][1024], right ?

Also, i need to hold other descriptions in different arrays because they describe different things.
Is it retarded to use my code multiple times like a copy/pasta or should i make a function ?
Isn't it a bit tricky to return an array from a function? or can i return nothing and have my array filled with the descriptions from the text file just fine ?

(maybe i'll just have one big array and know exactly where the types of descriptions are stored)

>>55947913

>>55947563

>>55947929
>*array[16] is the same as char array[16][1024]
No. The first doesn't specify that memory should be allocated for the array members.

>should i make a function?
No idea what your code is like, but if you are repeating yourself then yes, split it off into a function.

>Isn't it a bit tricky to return an array from a function?
No. All that returns is a pointer. As long as you know how big the array is, or pass that back as well then there is no issue.

>or can i return nothing and have my array filled with the descriptions from the text file just fine ?
This is the idiomatic way. Pass the array into the function, let the function fill the array by side effect, return nothing from the function.

- no pattern matching
- EXCEPTIONAL PROGRAMMING
- it's mutable by default
- It runs on a VM
- it's forced OOP
- horrendous syntax, can't even do partial application properly

Yeah, exactly. What you are saying when you say char *array[] is that you are allocating an array of char*, pointers to other places in memory where the string is actually located.

Like so:
array = | 0x01 | 0x0A | 0xCC |

memory:
0x00
0x01 p
0x02 l
0x03 s
0x04
0x05
0x06 k
0x07 i
0x08 l

0x0A

OOP features are useful, there are indeed data types that should be tied to some methods. A lot of the paradigm might be extremist and crippling, but there's parts of it that are legitimately quality of life improvements.

This. VM-ing a smartphone will be taxing on your hardware if you don't have at least a decent dev box. So you can't slum around it either way.

>VM-ing a smartphone will be taxing on your hardware if you don't have at least a decent dev box.
I find it's not really that bad. The biggest problem is for android at least, little things behave different in the simulator. And it's impossible to gauge performance meaningfully in a simulator.

I've looked into Haskell. It's cool. But it makes it painfully hard to break out of purely functional code when it's better for your project to do so. That's what's so retarded about it for real work imo.

I guess it depends on the scale of your REST service, you could get away with something smaller like Flask if your project is not too big. Django itself is good for REST, its like a Perl server, only I can still read what I wrote a month ago.
However, I would not advise the usage of Django for dinamic websites. Django was made for request-response. Last time I checked, there was no support for server push (like you would use in a messaging app) so unless all you need is ajax I would stay away.
If you know php and don't know Python + Django, it's gonna take a long time to get something off the ground, stick to php. If you know Python, learn Django.
I couldn't tell you much compared to php. I left the php train way back when it was a dumpsterfire, all memes aside, I hear it's workable nowadays if you get a decent framework, but I wouldn't know.

>>55949658
Calm your autism, it's for the deployment script only. The backend is pure python, I'm not stupid enough to glue some shit up in bash for the actual server.

>>55948278
don't listen to these people. C++ knowledge is a good entry into C, and that book (the second edition at least) is extremely good. Doing C will not just teach you the language but since you'll have to use OS APIs to do some extra stuff, you'll also learn some POSIX from using it (or win32 if you're a masochist).

>>55949836
Java's """generics""" is absolute dogshit. Because it was tacked on later, it's all erased at compile time and replaced with downcasts to Object.

But that wasn't my point anyway. I wasn't saying anything positive or negative about Java as opposed to C#, it just pisses me off to see people say "it's just a matter of opinion" or similar to cop out.

>it's just a matter of opinion
Every programmer who's ever said this to me regarding programming langugaes is shit tier. Especially with clear cut cases with Java and C#.

Of course it is a matter of opinion ultimately, but most programmers who point it out are doing so to hide the fact that they can't explain the advantages of one language over the other.

>>55949925
thanks for clearing that up

>>55949895
Yes. Suppose you have a function with the signature

T first<T>(T a, T b)

With type erasure, the function can't cheat and change its behavior based on the values of its arguments.

>>55949952
kill yourself, there are plenty of subjective reasons to prefer one over the other, e.g. one might prefer the "comfiness" of C# while another might prefer the "strictness" of java

>>55949925
Would scripter be a good description?

>>55949960
>With type erasure, the function can't cheat and change its behavior based on the values of its arguments.
It can't do that without type erasure either. Do you know what type erasure is? Type erasure is just the absence of run time type checking.

the opposite of this statement is equally true, i.e. that C# is subtly worse than java in a million little ways. hence, if you want to claim C# is better, then at best it's a matter of opinion and dependent on your use case, you can't make an objective case to explain why C# is better than java in absolute terms.

C# is better than Java. It's the JVM that is better than the CLR.

C# has keywords that are contextual, enabling LINQ in a really nice syntax. C# has better support for using legacy DLL's that were made for and by other languages, even enabling the user if he wants to. You can have properties that are a language construct, not having a get/set using 'standards' that can mean nothing. C# enables you to pass a reference and have 'out' parameters in functions, so you can return more information.

Really, maybe the only thing that Java has over C# as a language is its enums.

typedef struct _Data {
    uint16_t a;
    uint8_t b;
} Data;

std::vector<Data> src;
std::vector<uint8_t> dst;

How can I copy the contents of src to dst with std::copy? I'm not sure how to cast this.

I got a $25 gift card to Barnes and Noble using my good boy points. What are some books on more advanced subjects in Java that someone can recommend (e.g, machine learning using Java) or other languages if you think Java is a shit. (I use it because my University prefers it)

Lazy devs or devs who actually want to spend time adding functionality to a product and not waste time writing masturbatory environment setup scripts that add no value?

That "isa", is that a lambda?
