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) ===|
C:\Users\Zenheart47981\Desktop\brogue debug folder\Brogue-windows-v1.7.4\Brogue-windows-v1.7.4\Brogue Source\PlatformCode\main.c||In function 'main':|

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

>>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?

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

Learning Ruby Neckbearded Basement Dweller 15/12/17(Thu)00:12 No. 4835 [Reply]

File 145030753443.png - (88.79KB , 959x833 , ruby.png )

so, I am going to start learning ruby because I am a basement dwelling neck beard and I have no life.

So, I figure I might as well learn how to program and thought ruby would be a good place to start.

What are some staples I should know about ruby and programming in general, really?

AFAIK "Learn Ruby The Hard Way" is still free, and not only is it the one good thing that joker wrote, it's also the best thing he did. Which is why he wrote it first, and then moved on to things he didn't understand as well... which is almost poetic, if you like bad poetry.

LRTHW works, though, and I'd suggest starting there, if you're dead-set on ruby. It's ~slightly~ easier than Python, but I'd really recommend py at this point. It's more applicable; frameworks built around Ruby are worth learning if you know jack shit about MVE or whatever, Python will inevitably lead to you checking out the differenced between 3 and 2.7 and goes right into pentesting. So idk man, it's blub, but it's a good blub to help you get into learning how languages work.

I haven't encountered this error so I will just outline what I know since I don't have problems. Mednafen has no GUI, meaning you cannot just run the binary. If you are on Windows, you need to drag and drop the ROM(can be archived aka in a .zip file) on top of the Mednafen.exe and it will open up. Linux users can use the terminal, mednafen romname, ez. You can also use an unofficial GUI like https://sourceforge.net/projects/medguireborn/ which even comes with a Windows compiled server executable for hosting online servers. Most settings are controlled in the mednafen-09x.cfg file found in the emulator folder or ~/.mednafen for Linux, this is where you would for example turn off filters or turn off aspect correction making everything stretched if you want that. To bind controls you would use the hotkey, ingame, alt+shift+1, and press each button twice in succession. 1 can be replaced with 2 or 3 or whatever for whichever controller you want. That said I don't know what the fuck this has to do with programming

Neckbearded Basement Dweller 17/02/12(Sun)19:43 No. 4989

Also if it wasn't obvious, Mednafen is more advanced or as I like to call it pointlessly obtuse. I recommend newer users learn to use something like Retroarch unless you specifically want to use the very good online functionality of Mednafen or the primitive but fantastic new support of Sega Saturn (which doesn't have netplay support yet). Oh yeah, RTFM https://mednafen.github.io/documentation/

Neckbearded Basement Dweller 17/01/30(Mon)17:09 No. 4985

finally, someone else who knows about FORTH.

Neckbearded Basement Dweller 17/03/12(Sun)22:50 No. 4998

I think it has a lot of potential. Still learning, want to implement a microkernel of sorts on it.
Does it work well with embedded systems?
