Programming Puzzles

[exussum0]

Though the site implies using python, here is a site that can be fun for all programming languages

http://www.pythonchallenge.com/

You get a visual clue that you solve by writing code. The code you write is based on the clues and hints they give you. Once you solve it, you can go onto the next puzzle by using the solution from the prior puzzle in a mini-puzzle fashion.

An example might be, you are at http://bob.com/puzzle1.html. You may get a problem who's solution is to strip out z's out vowels to see a message. The message becoming clear text would be a hint to strip out vowels in the url, or some part of the url. Anything in the page is a clue, such as the title, the source code for it, images, sounds, anything.

It is certainly a new twist on these style of puzzle sites, like http://deathball.net/notpron/, which is NOT A porn site.

Lots of fun. We should start a wiki for discussing the Perl solutions. :-)

Thanks for that post! I'm stuck on the third one number three (bodyguards), if anyone cares to post a blacked-out hint for me, I'd appreciate it ;)

Update:
Changed which puzzle it was =)

[exussum0]

Highlight this node to see the hint for level 3. (

They give you 3 translations. They have something in common.

)

[exussum0]

The body guard solution for level 4. Highlight the node. (

Use the source luke. Read the hint and take it literally. How would you go about using the hint w/ the text.

)

FYI, the Python challenge was also discussed here

Hmm... I'm looking at number five, and I've got this instinctive sense that it is an inside joke for people who know python (which I do not). :-/

Like maybe there is some library or keyword "pickle" or some thing similar in python. That, or I'm missing the point :-)

[neniro]

Maybe this is useful (i haven't seen the riddle): pickle is serializing in python, like storable in perl.

[etcshadow]

Dang. Seems like the end of the line for using perl one-liners to solve the python problems. Once they're asking for binary-compatible answers from python... I guess I'd have to use python to go further.

[exussum0]

If you google around, you'll find the solution to this one, level 5. Consider that the puzzle in itself.

Solution (

it turns out to be a banner that says "channel"

)

The next one will prove to take a bit of effort, but after playing w/ their hints for a while, i was able to get something recognizable. Then it was a matter of shapping the output. It's much harder, I think, than doing it in python, but most are doable in perl too.

Can you really manage level 6 without using Python (and a recent Python at that)? Without giving too much of a spoiler, it seems like a critical bit of information is encoded in some way that the standard tools for working with this file format don't seem to be aware of. Update: nevermind. I needed to read the documentation more closely.

Yes, great fun, thanks for sharing!!
