If I remember correctly your program needs to exit successfully. There may also be a limit violation e.g. steps or height/width causing the challenge not to be accepted.

Cool! I didn't know about that. It took me longer to find the tab with the header info than to solve the challenge with telnet , but anyway, it's a great feature.

That's a quite general hint Most of the time at hacker.org you convert one number into another representation e.g. into hex or binary and then interpret things differently. I don't know of a format for such long floating point numbers.

Hm... I had no idea so far how to approach this challenge? Any hints?

You obviously did not read the HTTP specification, did you? See http://www.w3.org/Protocols/rfc2616/rfc2616.html You can not read something, which is not there! one.php does not exist! So file_get_content probably would read nothing... or an empty string. A HTTP request "consists" of heade...

You don't have to know anything about PHP to solve this challenge. Try to deal a little with the HTTP protocol and it's headers and status codes! And if you found out, what status code 302 means, you know why you only see two.php in your browser and why one.php not even exists. wget has options to d...

Is there any trick or do we just have to find out what programming language is used?

Google for "monitor color profile" to find an answer for this issue!

Welcome to Hacker.org

Did the same. Reengeneering with 'http://java.decompiler.free.fr/' did not work for this class file. ( It worked for all the other class-files here -- hint !! ) You probably did not solve enough challenges to be able to speak about "all the other" java classes :lol: There are java program...

I'd suspect that your program doesn't do the login "right". In this case you play the game anonymously and losing all progress in the end. You should check your cookie handling... and of course your username/password, remember special characters need to be encoded too!

Yep. The information is still at the same place and is accepted as solution when entered.

The challenge is OS independent, although the tools to solve it are not always available by default.

I like your zsh version... going back to the roots... (even though it's nearly not zsh specific). I often forget that the paste command exists. It's very useful here, nice algorithm. The "real" execution time is at least 2 min, since you can't know before, that the solution is 12 chars lon...

Okay, now that we know that is really web-related, how about some real hints? Really.
I mean, a collection of dates could be nearly everything...
