Level 18

I couldn't make a solid block of time for this one, so just stared at the file and the clues in odd minutes over the last day. Then what needed to be done suddenly dawned on me, and it worked the first try. That hasn't happened often since level 0 -- and it didn't hurt that I wrote the main Python module of use here (which isn't much of a clue, but explains how I could picture the outcome before trying it -- and no, it doesn't relate to obscure properties of floating-point arithmetic ).

I found 2 more images, but it looks like the data are corrupt.

That's where I'm at too. Looks like it was going fine for a while there.

hmm. where the two differ, the data is somehow familiar looking...

Yes, I've found interesting results where the two diff-er. Unfoturnately, it appears that that's not enough to get to Level 19

i've got one of the three out. not sure what i'm doing wrong with the other two.

Stupid typo in code. First two are out. Still getting error with third.

Just another stupid typo. On to 19!

There's a third possibility

Found it!

On to Level 19!

Very fun level

How do I get the junk out of the file?
I've tried everything they have in common and everything they don't.

How do I get the junk out of the file?
I've tried everything they have in common and everything they don't.

Try and see if there are any Python modules that could be of use.

Hint: keep the junk in line.

My mistake was to look for one result instead of three.

I don't find that hidden file.. Do I need a cookies' recipe ?

I found that the image has some extra informations encoded in it but I don't find how to extract them...

Any additional tip ?

As the page source suggests, try something obvious first. What's the difference?

That doesn't sound obvious to me .
