THe solution even works in Java !!

An Urban Dictionary is helpful when you are not english (or american) native-speaking.
For me - as a german - i've never heard of that word before.

On a physical RS-232-Line there can be 1, 1.5 or 2 Stop-Bits

Cereal => Serial
I even had a look in the RS-232 Spec. though this is in the 'crypto' Section. Nothing found out yet...

Perhaps C-Real -> Floating Point -> Arithmetic Coding. But also -> Dead End...

Finding some of the numbers in http://oeis.org/A081130/table definitely costed me a lot
of wasted time. I should have looked at the name of the executable earlier and no, it
has nothind to do with http://en.wikipedia.org/wiki/Maximal_fu ... l_function.
Now i got it.

Takes ~7 Seconds with the right optimizations

Before easter it worked for me, but now i'm stuck on my rank...

I think, the solution is not format-dependant. It would also work for a bmp or tiff - file. Analyzing the png-internals returned nothing for me. No alpha-channel or so... Still difficult, since i have no idea what to look for. I tried all sort of Photoshop-tricks like searching for colors only exite...

After finding the recursion long eL(long l10) { if (l10 == 0L) return 0x8a74526L; else return lC(l10 - 1L) ^ sy(l10 - 1L); } long lC(long l10) { if (l10 == 0L) return 0x8a74526L; else return sy(l10 - 1L) ^ eL(l10 - 1L); } long sy(long l10) { if (l10 == 0L) return 0x8a74526L; else return eL(l10 - 1L)...

One mistake by 'tidying up' and the result is wrong. Be more careful.

Is an image manipulation programm the right tool or do i need a hex-editor
just like in the 'Filtration Residue'-Challenge ?

Did it with bc

w5=sqrt(5)
n=150000000000000
l(1/w5) + n*l( (1+w5) / 2 )

Finally got it ! Sending the solution via the webbrowser did not work. I think the number is much to long to send via 'GET'. I don't know if the browser is the Problem but sending it via POST ( and a small java-programm ) did work. BTW : I dont know if this number is REALLY prime - but my solution w...

Perhaps there is an extra twist for non-US people as the place to look for the answer is not
very common for europeans. The 'draw'-hint was extremly helpful for me after
inspecting all(!) the german translations of 'draw'.

Very easy - decompiled it with 'Jad'
