Auf meinem neuen Video-Blog rund um das Thema „Programmieren in Linux-Umgebungen“ (das Thema ist absichtlich vieldeutig gehalten) biete ich kostenfreie Videos mit Grundkursen und Besprechungen von Programmiersprachen- und Werkzeugen an, die man auf dem Betriebssystem GNU/Linux zum Einsatz bringen kann. Über Zielgruppe und Konzept äußere ich mich in einem Begrüßungs-Video, das ich an dieser Stelle […]

xdraw 1.1
5. Mai 2017 in Multimedia, Programmierung.
I was very pleased to notice that my small Xlib-utility xdraw has made it across the years unscathed. It compiled after 11 years of complete lack of code or build system maintenance.

„jack-autostart“ – Setup and Start Scripts for jackd
9. September 2015 in GNU/Linux, Multimedia, Programmierung, Technik.
„jack-autostart“ is essentially a start script (I use it for my XFCE sessions) that starts „jackd“ with appropriate command line parameters and configures as many applications as possible to route playback to the JACK service. For this purpose, redirect all ALSA playback to JACK, and set JACK as default audiosink/-source for GStreamer.
