I'm hacking up a dynamic class loader, and I have all of the easy stuff done (dlfcn, dirent, etc.).
So the manager needs to know which container to construct based off the extension of the file that needs to be passed to the containers constructor.

The question then is: should I have the container shared object advertise which file extensions are supported or should I have it advertise a mime type?

My concern with using the mime type is that I would need a mapping from file extensions to mime type.
And my concern with using just the file extension is that there may be extension collisions.

Incase anyone is interested, I decided to implement the code analagous to the following pseudo-code:

for ( auto module : modules.equal_range( input ) ) {
try { auto module_class = module.second.constructor( input );
return std::unique_ptr< Module >( module_class );
} catch ( exception e ) { }
}

I let the modules advertise what inputs they support and use that do decide which loaded modules to attempt to create. In documentation I require that the module throw an exception if the input is not supported, or fails to load. I'll deal with the other issues related to that as I think of them.

I have basically none experience with advanced usage of computer whatsoever and O have no idea where to begin. I want to become the ultimate neckbeard.

Neckbearded Basement Dweller 17/11/14(Tue)06:47 No. 5086

I think it's kind of hard becoming a hacker. But mostly, the skills you need to train is knowing how computer network works in details.

Install a linux distribution. I really like Archlinux (hard to install, but you're going to learn a lot of stuff). Debian is also great.

Try to understand how computers interact with each other. What is actually happening when you browse the internet ? How does it work ? What is your browser actually doing when loading a website ?

Learn how to program. I recommend bash, C, python.

Understand what is a Network. Learn tools like NMAP and netcat.

Good luck.

Processing is a fun way to learn Java.

https://processing.org/

Khan Academy has a JavaScript version with plenty of tutorials. JS is a shitty language but it'll probably help you get some of the basics.

Learn C & Java
Start of with Java and as soon as you can write clean code start with learning C.

maybe you can use your programming skills to help develop and make these games better.

Friend is learning JavaScript as her first language. Should I stop her?

Neckbearded Basement Dweller 17/07/30(Sun)05:44 No. 5057

Unless she is specifically trying to learn Front-End Web Development with Front-End Frameworks, I'd recommend trying to get her to switch.

Python in general is a much easier more intuitive first language, and if we wants to do WebDev, the Flask framework makes it very easy. Once she is comfortable with Flask, HTML, and CSS, going into JavaScript, Front-End or Server End will be generally much easier.

results.Sort((g1, g2) => g2.depth.CompareTo(g1.depth));

Can someone explain to me what the hell this C# does?

results is a System.Collections.Generic.List

It's some kind of interface shortcut I guess? But what is => and why write it like that, does it save CPU cycles or just time for the coder himself?

Function currying and lambdas combine to make a thing called Streams (as my college puts it anyway), they are not quite the same as a filestream, however.

It's a great thing to learn, a bit tricky at first but can eliminate the need for complicated nested loops with slightly less complicated nested lambdas.

Thanks for explaining! I think I'll need to do a bit more research on lambdas before I grasp them.

I just failed a job application over a bizzfuzz. Please tell me what I did wrong.

Hey /pr/ first time getting into programming a debug mode for brogue and I'm gonna learn to do some miscellaneous programming, but I want to make brogue into a debug form, but when I try to do so, I get this:

||=== Build: Debug in Brogue (compiler: GNU GCC Compiler) ===|

The curses console is undeclared, but how do I declare it?

Neckbearded Basement Dweller 17/04/09(Sun)06:20 No. 5037

>>5036

Have you looked specifically in all files you've imported?

When I first attempted to do this on my own I get a different error, cursesConsole is undeclared, you have to declare it in a specific file?

Have you found any references for cursesConsole in different files?

Add this in codeblocks:

extern struct brogueConsole cursesConsole; in file platform.h.

Hi /pr/ i need some advice for creating my own chan board

Neckbearded Basement Dweller 16/10/30(Sun)06:14 No. 4949

Well I would start with getting what they are called correct.

Pick up, uh, php, python, perhaps some java script.

Neckbearded Basement Dweller 17/02/19(Sun)13:13 No. 4991

So what makes your chan different to other chans? Are you bringing anything new to the table?

Neckbearded Basement Dweller 17/03/17(Fri)15:42 No. 5003

Sperg out and try to make solar powered weatherproof server repeater boxes, like the guy who wanted to start spacechan.
