Koedo LUG (Linux Users' Group) Koedo LUG is a local Linux users' group that has been holding monthly Linux/open source study sessions in the Tokyo metropolitan area of Japan since 2003. The results of the study sessions are compiled into a booklet called "LinuxUSER" by a group of volunteer presenters and distributed at the twice-yearly Comic Market. The activities are also introduced at open source conferences held around Japan, and this series of activities has become an ecosystem for recruiting new members. This time, we will borrow a conference room from SIOS, a Japanese open source vendor, to study Linux/open source on a wide range of topics from embedded to cloud. After that, we will have a party to celebrate the event.
