Morten, Johannes und Willi sind da. Die Rechner fahren sehr langsam hoch, weil da jetzt Android-Studio installiert ist (sagte und Frau Spyra).<\/p>\n

Morten, Johannes und Willi reden \u00fcber Minecraftserver. Und dar\u00fcber, mit welcher Tastenkombination sich neue Fenster im Browser \u00f6ffnen lassen bzw. neue Tabs (strg-T). Mit strg-N geht ein neues Fenster auf. Mit strg-Shift-N geht das zuletzt geschlossene Fenster wieder auf mit der Seite, die dort zuletzt aufgerufen war. Angelo kommt auch.<\/p>\n

Wir wollen was mit SDL machen. Geht auch in der TTY-Konsole.<\/p>\n
