Project Euler - sealfin - Mar 13, 2013 11:10 AM
I'm just curious whether anybody here has participated in Project Euler? If you have, have you ever referenced Project Euler when applying for jobs or to schools/colleges/universities/things of that ilk?
I learned of Project Euler in December, and started solving problems a fortnight or so ago to try to achieve Level 1 by the end of the year (I have a... rather low opinion of my mathematical ability )

Haven't played with it myself, but I participated in an interview (as an interviewer) at a previous job where a coworker of mine brought up a problem from Project Euler to test our interviewee. Can't hurt to have that skillset under your belt.

I've looked at the website and solved some of the problems for fun. I never registered an account or anything like that though. How do you achieve Level 1? By solving a certain number of problems? (Don't have that much experience with job applying, so not quite applicable question for me).

This looks fun as hell! I immediately registered an account.

Looks like you level up for every 25 problems you solve. Once you solve a problem you can access a thread about it and discuss the solution with other people. It seems like a reeeeally cool little rabbit hole.

I'd not heard of it before today, but I did a few this afternoon.
You can friend me with this code:

This is bad. This is really, really bad. I'm 10 problems in and my eyes are bleary. I haven't done anything else since the post I made above. I'm trying to make myself stop but I peeked at #11 and I know how to do it. It would just take a little while. I could just not sleep and do it real quick.
O gods, what have I done?

Yeah, you gain a level every twenty-five problems you solve, the maximum level being fifteen; you're also able to gain awards, eg. solving ten consecutive problems gains you the "Decathlete" award, though the only award I've gained thus far is:

The first rule of these problems is definitely, get a bignum library, or a language with one built in...

Haha. I'm surprised you guys haven't heard of it:
Here's my code: 97156062452226_f98c8789267e769bdb1749698506fc21
I think I have a source code file where I solved a few problems a while back.. Going to go find it.

For those of you following along at home, OS X's default Ruby has a horrible bug with the Fixnum->Bignum transition which will give incorrect results for a large range of computations.
So if 19**15 gives you a negative number, this is why:
and here's a horrific workaround I found:

So, that's Level 1 and this year's target hit

I'd assume that everybody here is already aware of this, but on the off chance that somebody is not: Project Euler has been (partially) offline since Sunday (15th June) due to a security breach, and it has been reported by Project Euler staff that it is "highly likely" that all email addresses and passwords have been compromised – according to Project Euler staff passwords were salted and hashed... but the salting function has also been compromised.
RE: Project Euler - Zorg - Jun 23, 2014 04:03 PM
Well I don't think my password on there is used anywhere else; phewf.
RE: Project Euler - MattDiamond - Dec 4, 2014 06:10 AM
FYI it looks like Project Euler is back. For a while the problems and solutions were there but there was no logging in, so your progress wasn't tracked.
I'll have to dig out the problems I worked on earlier in the year and submit them.
