lol okay lets benchmark[/QUOTE]
I missed the part where he didn't actually use those strings for anything useful. The code is so crypic I couldn't make out what he was doing. I feel like an idiot now. :\

So, if he [i]actually needed [/i]those ascii-encoded-binary strings, a lookup table would be the right way to do it. But he doesn't need the ascii-binary strings to do base64 encoding.

Honestly, I can write code, but I can't read it for shit. It's like some sort of horrible curse.

[mutated]

the non-programming observers don't know [i]what[/i] the hell the difference, theoretically, is between generating the codes on the fly and culling them from a table.

so, me.

is there a different part of the computer working around this? GPU cycles were mentioned but I'd like to hear a more thorough explanation.

[Octave]

I just wrote it how my head would do it, haha. I did it like this:
3 characters:
01110100 00111010 01000110
take base64 value of first six bits of the first char, store the last two, append the first four of the second char to those and find the base64 value, store the last four, append the first two of the third char to those four, take the base64 of that, and finally take the base64 of the remaining 6 bits.
I wish I had known about the bitwise method, but if synthiac could have just told me that much earlier instead of acting superior to me it would have been better.

I think my method was just more convoluted than the bitwise one... My method used more memory by storing the table and various bits as strings. In truth, my method probably used more CPU cycles than the bitwise one due to its length. Bitwise operations are the easiest operations for a CPU to perform, so that explains the speed of it.

[ROBO_DONUT]

[QUOTE=synthiac;33517501]could you point me to where i was supposedly acting superior?[/QUOTE]
You never clearly explained what he did wrong.
You just said his method was "nieve" and responded with tings like "wow, just wow".

If you had clearly explained what he had done wrong, the debate wouldn't have gone on this wrong. It's late, I spent all day (literally [i]all [/i]day from 10AM to now) working on an assignment, I'm exhausted, and my brain can't grok information right now. On any other day I probably would have picked up on it right away. But not today. So a little help and patience would have been appreciated.

Giving tiny snippet of code, not explaining it, not taking my code seriously or even explaining how to use yours efficiently and going for a "zing" type reply at me.

I'm not sure if you have something against me or if you're an asshole all the time, but I think people would appreciate it if you were nicer.

I meant to get some programming done today; I really did.
Instead I spent 3 hours reading about molluscs on wikipedia

Explanation:
- Match 'href="members/'

- Match '-'
- Capture anything until a '"' is reached, then stop

All of you stop it.
Let's not have the best section on Facepunch go to shit.

Anyway, I'm learning java so I can do android stuff, and I'm most of the way though a TicTacToe game.

I'm pretty sure you'd want ([^"]+) ? (It'll capture 1 char only with your method).

Working on rendering Mandelbrot in Love2D. I have a working complex number, but now I need to figure out arithmetic with complex numbers.

I figured out that absolute values of complex numbers are the square root of the real number squared plus the imaginary number squared.
[img]http://i.imgur.com/Vg4bP.png[/img]

But now I can't figure out how to apply the formula z = z^2 + c to the complex number, in code. I would assume that it would work like this, but it doesn't output the correct values.

-- z.r = -1.468, z.i = 0.4
-- c.r = -1.468, c.i = 0.4
z.r = z.r*z.r + c.r
z.i = z.i*z.i + c.i

-- so it works out to be this
z.r = -1.468 * -1.468 + -1.468
z.i = 0.4 * 0.4 + 0.4

-- z.r = 0.68
-- z.i = 0.56
-- when z should equal
-- z.r = 0.52
-- z.i = 0.77

So thats my problem. Anyone here in WAYWO know how to correctly multiply complex numbers or apply this formula?

[editline]e[/editline]

Figured it out. The way I need to multiply complex numbers in code is:

local nz = {} -- use a buffer so i can compute the correct values
nz.r = (z.r*z.r - z.i*z.i) + c.r -- z = z^2 + c for the real part
nz.i = (z.r*z.i + z.i*z.r) + c.i -- z = z^2 + c for the imaginary part
z = nz -- push the buffer onto Z

Got GMod spitting out videos into VP8. 10FPS at 1920x1080. Pretty slow, so probably no good for realtime stuff.

Well we're working with complex number in math class and when you want to square it you first translate it to trigonometric form then the square is r^2(cos(2*angle) + i*sin(2*angle)).
