That was pretty fun. Good for a Friday. Too bad it comes to an abrupt
"temporary end".

P.S. I hope I didn't hammer your server on step 3. I was missing the

Ironically, I just used Unix tools (tr, grep, sed) for each of the
puzzles except the first one, and that first one was only because I tend
to use Python as a convenient calculator anyway :-).

Interestingly step 3 is actually wrong... there is an additional
solution, which looks like cqqmsxk. (I don't think that spoils the fun :))

You're not the only one. This is where I am currently stuck. It's starting to
hurt my head.
There are 478 results in the form *BBBsBBB* but the thing said 'exactly'
right, well there are 10 results in the form *sBBBsBBBs*
None of them seem to work...
I quit ;)

That was fun. The very first step in 6 was the most frustrating I
thought.

I did the same thing. Now just combine those ten results.

3 IS wrong because if you use any not BIG letter after bodyguard on both
sides, you get extra 'eCQQmSXK\n' which slow me down for 5 minutes.

Get rid of the newlines first.
On level 7, I'm not sure whether there's something more to do, or
whether I'm looking at a bug in how IE displays .png files. Using
Windows is good practice in solving maddening riddles every day

The same thing happened to me, but then I figured it out.
Hint: Print all 10 results in a column.

Strange: I don't find eCQQmSXK\n, only eCQQmSxK\n. I guess the data has
been modified in order to get that potential confusion out of the way.

They've added at least one more level since yesterday. Unfortunately,
I'm stuck on it.
Dan Bishop
Correction: Now I'm stuck on Level 11. I think I'm supposed to do
something with the pixels in the image, but what?

Me too. I've tried making different images out of the even and the odd
pixels, but nothing interesting happened. I tried to combine both images
in various ways (using the Gimp), but that also seemed to be a dead end.
I don't think we need to concernt ourselves with the individual pixel
values; otherwise the image would not be a jpeg, it would be a non-lossy
format instead.
The forum's tips only go up to 9, so that doesn't help either.

There's a new image on the website now (still the same name though); I
solved the riddle now :-)
There's no level 12 yet though.

Now there's a 12 and a 13 (at least!).

You only got 2 images?
*** SPOILER ALERT ***
Split them again to get 4 images with (even, even), (even, odd), (odd,
even), and (odd, odd) coordinates. Two of the resulting images will be
useful.

There is "zip" in the page source, "ZIp" in the

Have you found the zip file yet?
(I did, and I still can't figure it out. I'm wondering if there are
comments embedded in the jpg that none of my viewers will show me.
Hmm, maybe there's a python module that does that... I'll play with it
more after I sleep on it.)

It's best when you use the zipfile module.

Look carefully at the ZipInfo class for every file in the archive.

Is that on the original image, or the new one? I solved it with the new
one, but I'm still unable to do find the solution using the original one.

Cool. I had just unzipped the zipfile, and was looking at the files
directly. The comments weren't added to the files in the OS, so I was
only thinking about jpeg comments (since the photo was also a "zip").
I love the way this challenge is making me poke into pieces of the
library I've never used before. :)

Any hints for level 13? I know how to make a call, but don't know "who"
to call.

Ah, thanks. I tried having both sides identical, no results. Then I tried
the above re but stopped at the first result :-(.

Hmmm. The title of the html page is "dealing evil". If you were
playing war instead of solitaire, how would you change how you deal the
cards?
-John
P.S. - I think I've found everything, but still haven't figured out what
to do with it. No hints yet, though. I want to think about it some
more...

Well, I'd deal them into 2 piles, and...

Okay, so I've been working on level seven for a LONG time now. I've
decoded the first message to get the hint for the next level. Using the
same tactics, then I decode the hint as well, but there are non-printable
characters. I've tried stripping out those characters, quoting them to
include in the URL and various anagrams of the printable characters, but
nothing works. Does anybody have any suggestions?
Thanks,

Roel Schroeven
I just took a guess for the first of those non-printable characters, and
proceeded from there. I thought it was going to be too simplistic, but
it worked. And fortunately my first guess was the right one.

Hmm, I didn't get any non-printable characters, just a regular English
word to be used to get to level 8. I think you guys must be doing
something wrong...

Hmm. I've been staring at that one 18 hours a day since last Friday,
and still don't have the foggiest idea. I've counted boxes, counted
pixels, broken it apart and rearranged it like a jigsaw puzzle, ran
"strings" over the .png, ..., all in vain.

Count boxes, count pixels, break it apart and rearrange it like a

That's a funny one: I didn't understand the "pronounce it" hint until
long after I solved that one. Then again, Guido & I implemented PEP
307, so I knew what to do the instant I saw the file <wink>.

[Dan Christensen, gives a huge hint]
The first time I looked at it, I thought "hmm, I should use PIL for
this". I kept thinking that too <wink> -- but for some reason wanted
to see if there was a clear way to do it without something that
"fancy". I eventually gave up and did the obvious thing (and of
course that worked).

You don't really need the remember the solution; it's more the process

I might need the missing piece for level 13. Anyone else encounter this?
Michael
Roel Schroeven
Indeed, there is one I could not open properly. One tool I tried gave a
warning and an incorrect image, another one showed a cropped image of
what I suppose should have been the real image.
I tried some variations to get an uncorrupted object, but didn't succeed.
However, I didn't need it for solving level 13.
When all else fails, try Google. It helped me, in any case.

Nope, that piece is just a truncated version that opens fine otherwise
in Firefox which then gives you the piece that you correctly guessed at;
no hints there.

Yup, I found it. How evil and devious. I found the hint without
Googling, BTW, but can see how Google would have led you to the
solution. I for one, will never again believe the claim there is no more
evils..

No, there is a hint in level 12. Remember how you could manipulate the
URL of the image of level 12 to get to the data file for that level. Now
continue that manipulation and don't believe the suggestion about no
more evils. *Then* pay close attention to what you find. If you get a
'Not Found' you either didn't pay attention in the previous step and
have passed over the hint, or you searched in the wrong direction.

It isn't meant to be too obvious.. If you're expecting obvious
solutions, you won't like the rest of the challenge. ;)
What have you tried? Have you studied the source of the page, tried the
link, seen what you get back from that link and then adjusted the URL
according to what you got back? From there on out, just follow the
chain, the linked list.

This is not only about riddle lovers, but a great way to advocate python
to other programmers... I already had a session with a friend (he did
the thinking, I did the programming next to him) and he was enchanted :)
I'm already investing a little time to think some new riddles to suggest
(extending stdlib coverage).

The On-Line Encyclopedia of Integer Sequences should be better known
-- it's an amazing resource:
http://www.research.att.com/~njas/sequences/
It knows about this sequence, so don't use it unless you want the
answer given to you. If it doesn't know about your sequence,
"perfectly good" is debatable <wink>.
