last month , when leaders absent in office, I took the chance to read ESR's The art of Unix programming . What a great book it is ! but i also should alarm myself that book is just book, concept just concept, knowledge just knowledge. If all of these can't fit to pragmatic utilization, they 're just garbage , at least to the projects to which ideology can't be adapted.
in terms of this , I should respect Maozedong 's revolutionary theory-take it as it is. not for theoretic perfection, not for conforming to authorized believing , just for mission completion and mortal victory.
