OSMC 2019 | NeDi – Why it’s still here by Remo Rickli

120 Aufrufe

Veröffentlicht am

It contains a lot of features in a user-friendly GUI for managing enterprise networks. When the project started around 18 years ago, there was not much else around. With many successful open source projects appearing in the meantime, it’s a different story today. So why is NeDi still alive and kicking?
