Oberon (moon) geological feature on Oberon: craters and chasmata ('canyons'—deep, elongated, steep-sided depressions which would probably be described as rift valleys or escarpments if on Earth). Oberon's surface is the most heavily cratered of all the Uranian moons, with a crater density approaching saturation—when the formation of new craters is balanced by destruction of old ones. This high number of craters indicates that Oberon has the most ancient surface among Uranus's moons. The crater diameters range up to 206 kilometers for the largest known crater, Hamlet. Many large craters are surrounded by bright impact ejecta (rays) consisting of relatively fresh ice. The
Oberon (operating system) PC-Native Oberon. Other versions of the Oberon System, i.e. without "Native" in the name, had partially modified interfaces of low level modules. In 2015 Peter Matthias revitalized LNO under the Name OLR (Oberon Linux Revival) as a multi-platform Distribution running seamlessly under Intel x86, RISC-V, MIPS, and ARM. It runs nicely on the Raspberry Pi and on the inexpensive CHIP computer; with some tweaking (adjusting group membership or/and permissions on some devices) it runs nicely under Tiny Core Linux. OLR interfaces with Linux kernel by direct System calls. OLR currently (mid 2017) misses a network layer. In 2013 Niklaus Wirth
