Maybe we should have an HN poll for "best engineering team", rather than each startup claiming to be one. I for one would vote for typesafe. Or precog. Pound for pound, there's more value per developer in those two companies than anywhere e

Well, lets say you have 3 elements (1,2,3) with 2 being 0. So since 2 is 0, 1+2=1=2+1, 2+2=2, 3+2=3=2+3. With me so far ? So what's 1+3 ? Well, it cannot be 1 because you could then cancel the 1's and 3 would become 0, but 3 isn't 0, its 2,

Ah! In that case, professor, a couple more caveats. Chicago prop shops notoriously underpay. The IB's pay higher, but still less than google/fb/twitter. All of my uchicago classmates are in finance with roughly 50% in chicago, rest in nyc.
