    1.34 +Ein Vortrag von \fBMarkus Schnalke\fP
    1.35 +über die wahre Genialität von Unix.
    1.36 +.P
    1.37 +Unix ist ein beeindruckendes Betriebssystem und eine 
    1.38 +erstklassige Programmsammlung.
    1.39 +Doch dies ist beides letztlich nur eine Folge.
    1.40 +\fIDas eigentlich besondere an Unix ist seine Philosophie.\fP
    1.41 +Die Unix Philosophie ist eine Sammlung von Konzepte und
    1.42 +Designziele die in Unix umgesetzt wurden.
    1.43 +.P
    1.44 +Dieser Vortrag wird die Unix Philosophie vorstellen
    1.45 +und erklären weshalb sie zu hervorragender Software führt.
    1.46 +.P
    1.47 +Neben den rein technischen Aspekten bietet die
    1.48 +Unix Philosophie aber auch Anreize für das tägliche Leben.
    1.49 +Sie ist mehr als Richtlinien um gute Software zu erzeugen,
    1.50 +sie ist eine Inspiration in vielerlei Hinsicht.
