\begin{slide}{Geschichte}
|
||||||
|
\begin{list}{$\bullet$}{\itemsep=1em}
|
||||||
|
\item<1-> „All window managers suck, this one just sucks less”?
|
||||||
|
\item<2-> Desktop environment vs. window manager (GNOME, KDE, Xfce, …)
|
||||||
|
\item<3-> Stacking (e17, fluxbox, IceWM, fvwm, …) vs Tiling (dwm, wmii, xmonad, …)
|
||||||
|
\item<4-> dwm, awesome, xmonad, …: statisches Layout
|
||||||
|
\item<5-> wmii, ion: dynamisches layout
|
||||||
|
\item<6-> Problem an ion: tuomov (Lizenz, Kommunikation), Config, Look and feel
|
||||||
|
\item<7-> Probleme an wmii: Xinerama-support, Xlib, undokumentierter code, nur Spalten, keine Reihen, Kleinigkeiten (titellose Fenster)
|
||||||
|

|
||||||
|
\item<3-> Sinnvoll benannte Funktionsnamen und Datentypen
|
||||||
|
\item<4-> Threadsafe (nicht dass wir das bräuchten, aber…)

\item<5-> Nutzt die Asynchronität von X aus
|
||||||
|
\item<6-> Dokumentation? Ne, das ist was für Anfänger.

ISO 10646 = Universal Character Set, selbe Zeichen wie Unicode
