a few people were trying.  It was discussed a bit on the FB IRC channel.  

The technique being used, was a brute force, looking for a complete border around the image.  I used a slightly modified verion, looking for more patchy borders, prepared to take more false negatives.  

However, I, and i guess the others, got bored after i let it run for about 16 hours.  I actually recoded the inner loops of mine in ASM, and it was still very slow going.  I think i was trying about 5-15 thousand numbers per second, when it was at full speed, but most of the time, i couldn't run it this fast because i wanted to use the machine for other stuff.  

Considering though, it needed to try 4 billion combinations, it was going to take too long, and i could not be guarenteed that there would be a border as such to find.

I'd be interested to see the actual image, and know the number pass, to see if what i wrote, would actually have ever cracked it, given the time.

None of use expected you to pay if we did get it, and i don't think it took anyone longer than an hour to write their program.

wow. that's alot to process. (no pun intended) where did you say this was being discussed? link?  Cheesy i seldom travel out of QBNF.

well the seed number i used to encrypted it was 10011100110111010001 (just convert to decimal)

immature: yes
arbitrary: you bet
retarded: It's my creed. (retardizm that is)
false: Proud to so say it is.


tell you what. if i post a harder pic, i will guarantee 100. (pesos)

The far right side was solid. Cha0s code would have caught it but it didn't work with my version of fb and we thought we already eliminated the numbers below 1mil. *mumbles*

Have another look, the far right side is not solid, its a gradient, from

RGB(243, 0, 0) - RGB(250, 0, 0)

so the solid border technique won't catch it.

I might have nearly caught it, as i tried re-rendering the original image down to 16 colors, but that yielded too many false positives to check.

Well done dio, i doubt anyone could break it, without some kind of character recognition, which would have made it so slow, as to be near impossible, without a massive effort of many machines.

here was the image i croped it from.

SCREENRES 1024,768,32,2,1
r =255
FOR ww = 0 TO 1000 STEP 1
  r = r - 1
  CIRCLE (1024/2,768/2),ww,RGB(r,g,b)
  CIRCLE (1024/2+1,768/2+1),ww,RGB(r,g,b)
  CIRCLE (1024/2+2,768/2+1),ww,RGB(r,g,b)
NEXT
SLEEP

with the text being at the top left hand corner. (1,1)

I didn't even bother.

As for temperature, think 14-20C daily, and overnight, bordering on zero or a bit below.

And it's perpetually always raining and I hate it.
