Chemnitzer Linux-Tage (Chemnitz Linux Days) is happening this year from 19 to 20 March 2016. There are both German and English tracks with this year being around 90 lectures and 15 workshops.
Chemnitzer Linux-Tage last year had more than three thousand visitors. The event continues to be community-oriented and the registration cost is just a few EUR. This Chemnitz, Germany Linux event has been happening since 1999.
While sadly I will not be attending the event this year due to the Phoronix conference/travel budget still being suspended, if you are interested in learning more about Chemnitz Linux Days, visit Chemnitzer.Linux-Tage.de.
