All those fancy applications are nice, but only as long as data flows in and out. Other developers take this for granted, but you know its anything but.
You know a lot about packets. You have experimented, even tried to verify your own implementation of RFC 1149 and 2549 (and we don't even have to provide a link here, do we?). You've tweaked VCL itself, started to hate clumsy Linux kernel there and still ended up sane. You consider most developers reckless, as they do not consider performance implications of TCP enough.
You laugh at what realtime web considers realtime.
But infrastructure is boring, configuring switches or even BGPs is not for you. At heart, you still want to deliver product. And you are going to find that synergy in Prague as you are going to write us.
