Earlier quoted context omitted.

Less than 40 lines total for the subproblems, including white space. Less than an hour (if you don't count checking email in the middle). Would have been slightly faster if I had thought less and brute forced a bit more. A crazy old friend used to say "Don't underestimate brute force and ignorance"! :-)

I though about a more elegant approach and then just brute-forced it too when I realized a brute-force solution wasn't really very expensive. cloc shows 7 lines of perl code for my part 1 solution and 22 lines for part two. [edit] time for my part 1 solution was 7.8 seconds on an old Dell 2650

Totally different number of lines. Also Perl. 24 lines part 1 (OK, with some diagnosis printing) and 15 for part 2. (That includes use strict;/use warnings; and a few empty lines for both.)

For part 1, with 'time' got real 0m2.865s, user 0m2.780s on a T60 Lenovo/"IBM". I used a few minutes to think about the brute force, which probably saved me half the execution time.

In pure percentage of loss/earn, those minutes for three seconds was probably the worst business of my life... :-) You can take the C/C++ compiler from the old nerd, but you can't stop him from doing premature optimization. :-)

Why do you need a business co-founder and a technical co-founder? I guess I'm just wondering what your role in the company is?

I am looking for one or the other, I am doing both right now and am looking for someone who can offset one of them very well.

You should work out whether you are a better engineer or business person and search based on what's not covered.

EG: It would suck if you are a great engineer, and ended up with an ok engineer co-founder doing the engineering whilst leaving you with the business stuff (which might not be your forte). You could have had a better engineer (you) and a better business person (someone who is just business).

At a higher level, I wouldn't even look for a business orientated co-founder. Just get another developer, or if it's appropriate, someone who is more design and product focused. The business can take care of itself through advisors and just picking stuff up yourself.

Good luck!

Are you really finding it that hard to fill the position, or do you need more than one? Looking over your posts you mentioned looking for an entry-level dev about 300 days ago... Curious whether this is an indication of scarcity of developers in the greater Philly area or not.

We've hired two in about the last 300 days and continue to look for more. Your question does make it clear that the copy in the job posting is weird. I'll get it updated with something that doesn't make it seem like we've had no luck for over a year.

In terms of the scarcity, to me it seems like there is but I've only done hiring in this area so I don't have anything to compare it to.

What a fantastic way to differentiate your company. I had forgotten how much fun crypto is :)

I sent the problem to a few other friends (some of whom are actually looking for jobs!).

I understand. How long did it take you to solve it?

Less than 40 lines total for the subproblems, including white space. Less than an hour (if you don't count checking email in the middle). Would have been slightly faster if I had thought less and brute forced a bit more. A crazy old friend used to say "Don't underestimate brute force and ignorance"! :-)

I had about the same LoC for my ruby solution. Time was way longer because I had to read at least three wikipedia articles on various aspects of modulo arithmetic after I was so ashamed of my brute force solutions.

Wonder if anyone tried frequency analysis since that should work well on an affine transform...

Solved it, knowing an old math concept helped, did a Google search and got the values [writing the code to loop through the values for m,n was easier but felt someone must have computed them and posted on web].

Just wrote the code for cipher and used all possible characters and replaced using the encrypted value. Though I nearly sent it to the wrong address since it wasn't clear whether address contained the answer it self or answer%256. took ~30 mins [mostly to look up ord,chr and the solution on google].

final solution 12 lines python code, does not calculates a,b,c just the cipher and i/o.

I solved the problem, but before doing the real work of updating my CV -- could you please write a little bit about the job, to avoid wasting time for us both? :-) (And I know, it is not really a waste to update your CV.) Edit: For instance, are Europeans and other aliens a possibility? Edit 2: Thanks. But I've probably forgotten too much math. :-( And you should get enough people anyway, sounds like a cool place.

We have an automated trading system which plays the stock market and makes us a bunch of money. The job consists of extending the trading system, developing new strategies (note: strategy == code), and some maintenance work (making our FIX talk to their FIX, tax calculations, etc). You should be ready to be involved in all aspects of the company - specialization is for insects . Yesterday I did numerical optimization…

Java / Ruby is an odd choice for trading particularly HFT, everyone else I have seen seems to be using C++ / C.

Though its not as odd as compared to a quant [from a large bank which held an info session at my unive] who I met last week and told me that he uses VBA + Perl (for research not trading though).
