1. ### Do you even lift? What are your hobbies outside of the quant world?

Awesome feedback guys. Compound exercises it is. Proper form and perfect technique, got it. I'll start after marathon season ends. Actually had to google the overhead press and military press; they seem to be the same (I called them "raise the roofs" until now). Must get familiar with the gym...
2. ### Do you even lift? What are your hobbies outside of the quant world?

Interesting thread. I work in model validation and therefore, have loads of free time. Weight lifting / body-building is definitely on my list of hobbies to pursue next, but the training is quite different than what I'm used to. Currently, my thing is running marathons, kung-fu, and hiking...

9. ### Matrix Inverse Algorithm

Try A = LU decomp first (if applicable, even go for Cholesky if possible). Then, (if L and U are invertable), inv(A) = inv(LU) = inv(U) * inv(L), and inverting L and U are quick. Well, this works for me, 0.13 sec for 100x100, 18 sec for 500x500, 260 sec for 1000x1000, and my laptop is a dinosaur.

11. ### First order differencial equation

RK4 for 1st order ODEs
12. ### Interview Questions at JPMorgan Sales and Trading

Must be a lot of people on a 2 hour line. You obviously do not cut off the big tough guy but the one who you believe will not do a thing about it, also known as a little beyotch. Cutting someone on a line that big would be insulting, basically saying that "you can't stop me", so being passive is...
13. ### Anyone watching Wallstreet 2?

I should've listened to my wife and watched Easy-A or The Town...
14. ### What are you listening to now ?

You're not alone Andy. If you liked that freestyle 80's era then you'll like the CDO stuff, maybe...
15. ### We are Wall Street ... we are smarter

Big talk. I dare the author to come to my office and try to take my job.
16. ### Life of a quant

Unless of course you find yourself a quant wife. Try to check out if there is the possibility to log into your work PC remotely. Very convenient for those with families when things come up, and yet you can still be productive.

If someone needs that much annually to survive, then their survival skills must be really bad or they have a big hole in their pocket.
