I can't think of anything more gratifying than seeing something you thought up and worked on for days (and nights) run and do the right thing.
And I can't think of anything more
I've been sitting here now examining tons code, logging tons of info, sniffing traffic between different sections (client to proxy, proxy to backend) and I finally saw the problem... and it makes so much sense. And now I have a greater understanding the of the whole system, and where the proper place to do certain stuff is.
I've been on a "good" sleep schedule lately. Screw that. I have no early classes anymore... It's time to get back into late-night hackin'.
