Sometimes I think hacker attitudes are way too dramatic. "Precious development time", "... my baby." Discouraging projects unless they are "radically different." Commit 100% or don't bother! Utmost passion and dedication to your online power saving widget! GO BIG OR GO HOME!
A lot of really good software was created on a lark. Some of it even became financially successful. It doesn't need to be quit your job and drop out of school to make the next Google (using Haskell, this time) or else you're wasting your time.
That said, at my day job I have genetically engineered biomolecules to act as a massively parallel neural network which can design new derivative investment instruments on the fly and corner the market on them before other hedge funds even know they exist. As a clever side-effect, this process unearths retrotransposon based cures for AIDS hidden in "junk DNA". My work has been "certified green" because the biological residue from the computations can be dumped onto ocean oil spills and automatically transform the petroleum into vegan friendly biodiesel which swims to shore on its own. I have also hacked my roomba to perform an advanced form of lasik surgery which restores sight and plan on sending it on a world tour to communities in the rain forest afflicted with "river blindness." Hopefully these advances in the state of the art more than make up for the time I'm wasting on my boring photo site.
EDIT: gotta give a shout out to my homies at CERN for hooking one of my molecules up with a free trip to the 11th dimension after they find the higgs. thanks, guys!
