This is your only clue: http://en.wikipedia.org/wiki/Web_colors

Le bump. Can anybody figure this out?

I have to use wikipedia for a clue?

EHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH

A youtube channel called numberphile might also have some sort of clue.

Are there intentionally three different shades of each color in the image?

I spent an hour researching and then writing a program to calculate all 4+ billion permutations and they were all gibberish!

They all look something like this:

Zik!qskuskqs!qscis) {ku!cis{ {smskmk!mksikke)!Qk!ycku)!I!kq{!is.

I'll give a clue. Hexadecimal encoding can be used to encode just about anything. It just so happens hexadecimal values are used for colours too.

Yes I know

But each stripe in the above image (when you zoom in) has 2-4 different colors/hex values.

I calculated all 4 billion of the possible permutations of these hex values (as ASCII characters) and none of them made any sense

I have a feeling the image got compressed by the image host (its supposed to be a solid colour). I can't seem to re-translate it either. I'll throw you a bone and output another image.

You got it!
Want another decoding challenge? It will use integers instead of hexadecimal.

Woot! Yeah, let's try it

Please hint: should we operate on that as a string or as a number?

remember when i solved the other one (http://onemoreblock.com/forum/threads/y ... post-19834)
good times

Post these things on Programming puzzles and Code Golf!

Got it!

The solution code, in Python.
I didn't solve it alone, Seb helped me by hinting that it's a string of ASCII codes, that may or not have 3 digits.

Code: Select all

def split_chars(string):
    def getc(i, s):
        return string[i:i+s]
    result = []
    index = 0
    while index < len(string):
        if int(getc(index, 3)) >= 256:
            result.append(getc(index, 2))
            index += 2
        else:
            result.append(getc(index, 3))
            index += 3
    return result
  
if __name__ == '__main__':
    number = "10411611611258474711911911946121111117116117981014699111109471199711699104631186166839777488785815286115"
    parts = split_chars(number)
    chars = map(lambda x: chr(int(x)), parts)
    string = "".join(chars)
    print(string)

I now challenge you to discover the secrets of the following image (download it because it's tiny):
The answer to life, the universe and everything may be doubled and subtracted 20 for a useful hint...

The quick brown fox jumps over the lazy dog to shoot lasers at Martian aliens who plan on destroying Earth with radioactive cookies and evaporating all the oceans with body heat. Cool, huh?

Had to ask kroltan for some clues, and then turned out it was just a silly error in my code xP

My ruby code:

Code: Select all

require 'chunky_png'
require 'base64'

image = ChunkyPNG::Image.from_file('image.png')

base64Encoded = ""

(0..image.dimension.height-1).each do |y|
    (0..image.dimension.width-1).each do |x|
        c = ChunkyPNG::Color.r(image[x,y])

        if c != 0
            base64Encoded += c.chr
        end
    end
end

print Base64.strict_decode64(base64Encoded) + "\n"
