It's that "I've seen some shit" look -- a kind of world-weary daze of someone who has been through a few business cycles, several verses of the "this new language/paradigm/whatever will solve all our problems" song.
It's the look of someone learning yet another "teh shiny" just to stay current -- with full knowledge that it's yet another idea from the 1970s, repackaged to appeal to a modern audience.
The look of someone who simply lacks the energy to resist the zeitgeist. Who has to listen to everybody oozing religious zeal over the flavor of the week.
The look of someone who is thinking "cool, monads -- now can we roll up our sleeves and ship this product? Remember our product? We get paid for shipping product"
Core dumps, memory leaks, hardware faults, and plain bad luck.
Big O, data flow, always learning -- or out you go.
Manager metrics, schedules hectic, methodology hegelian dialectic.
Taking the heat, feature creep, open office, uncomfortable seat.
Holy wars, revolving doors, carpal tunnel, all you can take? There's always more.
Fucking suits, random reboots, and the ever present "thousand language stare".
Oh yeah, pressure -- lots of pressure. And time, time, time.
Metric shitloads of time.
Time, man. You gotta do your fucking time.
