Whenever such things require much labor, time, and reflection, the greater number who do not know, are made the dupes of the lesser number who do.

 We Must Apply the Scientific Method to Ourselves

If it is to be applied consistently, science imposes, in exchange for its manifold gifts, a certain onerous burden: we are enjoined, no matter how uncomfortable it might be, to consider ourselves and our cultural institutions scientifically and not to accept uncritically whatever we're told; to surmount as best we can our hopes, conceits and unexamined beliefs; to view ourselves as we really are. Can we conscientiously and courageously follow planetary motion or bacterial genetics wherever th...

 Hummingbirds are Proof of the Cost of Sex

If sex had no cost, hummingbirds would not exist. Hummingbirds eat nectar, which is produced by flowers to lure pollinating insects and birds. Nectar is a pure gift by the plant of its hard-won sugar to the hummingbird, a gift given only because the hummingbird will then carry pollen to another plant.

George Malamidis taught me something about code attachment a few years ago: You always gain by allowing someone to show you an alternative solution. If someone wants to solve a problem in a different way, there are several gains to be had. If their way is inferior, you have an opportunity to mentor a team-mate. If their way is equally elegant, you've gained another solution, or point of view that may be superior in the future. If their way is superior you learn something new and the codebase ...
