I did a dump of Project Euler sometime back. The script, code, and problems, and solutions are all on github [0]. The finished product was just a terminal-style UI to Project Euler called codebot. You can try it out at <a href="http://codebot.sdslabs.co/" rel="nofollow">http://codebot.sdslabs.co/</a><p>[0]: <a href="http://github.com/sdslabs/codebot" rel="nofollow">http://github.com/sdslabs/codebot</a>

How did they find out they were hacked in the first place? This is always interesting to me as I don't think Project Euler would have some sophisticated security logging audit system in place.

Well it's not back completely, now it's just a static site with the problem set restored. No ability to check answers or log in and track your progress.

Sad. Project Euler is pretty much useless without the problem checking feature. Anyone know a good alternative?

This is sad. Because of this they have sealed off the ability to check answers. Anyone know of a way to get all the Project Euler problems offline and their solutions?

The part about salting confuses me. Shouldn't salting remain effective against rainbow tables even when the salting mechanism is known?

The forum has returned, but OTOH when I try to log in it says it has no record of my username.

Looks like they have enabled answer checking again .

We changed the title to say "partly".
