Project Euler is partly back

[captn3m0]

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 http://codebot.sdslabs.co/

Thanks!

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?

A few months ago I made a gem to manage, run, and test project euler problems.

Did this pretty quickly: http://project-euler-solution.herokuapp.com/

Give it a shot? Don't have answers to all questions.

[abhididdigi]

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?

[captn3m0]

You can check out codebot[0] for checking your solutions. The source and problems are all on GitHub: https://github.com/sdslabs/codebot

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

[wolf550e]

crypto101 says that because of how fast GPUs are at computing hashes, even using long per-user salt is now broken and you must use pbkdf2 or better yet, scrypt.

[dnet]

It should, and they just said "the integrity of weak passwords cannot be guaranteed" -- even the best salting cannot prevent attackers performing brute force attacks; it will be slow, but weak passwords may be cracked in reasonable time.

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".
