The difference between theory and practice in theory is much less than the difference between theory and practice in practice. —Perler (seen from Randal L. Schwartz's signature.)
When the theory and practice type of mind-tickling word-playing quotes are quoted by the Perl and unix morons, there exudes a subtle implication, a indifference, that seems to suggest that there truly lies a logical wisdom that dismisses computer science or formalism being overrated. All is all right in the world, except that these Perlers and unixers minds are tainted by such unconscious affirmation to yield stupider and stupidier mode of thinking on computing, from programing languages to software methodologies. Thusly their “there is more than one way to do it” type of creeds become lodged firmly in these folks' minds as a unconventional but sound alternative principles, maiming themselves notwithstanding but harming the society and young by hegemony. These $Free$ and “Freedom” type of morons hog onto free things and roll like a black hole, sucking up poor students and encroaching the computing industry, to the degree that obvious falsities are being perceived as indubitable truths.
Last week i bought a chain-saw with a twisted handle. Perhaps i wasn't careful, but by accident it chopped one of my arm off, then i thought to myself “gosh, this is POWERFUL!”. This seems to be the fashionable mode of thinking among the unixers or unixer-to-be, who would equate power and flexibility with rawness and complexity; disciplined by repeated accidents. Such a tool would first chop off the user's brain, molding a mass of brainless imbeciles and microcephalic charlatans the likes of Larry Wall and Linus Torvald jolly asses.
Next time you hear someone quoting theory and practice, please secretly take a glance at their smugness, then snicker at these folk's stupor. If you are a kind man, point them to my opuses.
