Maybe you have an Windows program, but you don’t want to start your Windows virtual machine (or boot into Windows) everytime to use it. There is wine which provides a compatibility layer for Windows programs so that they can run on Linux and other operating systems.

When you create a calendar, like OOoCalendar, it’s nice, if the calendar already calculates holidays. One of the holidays, that is every year on a somewhat different date is Easter. There are many other Christian holidays that depend on the Easter day like 40 days after Easter is Ascension Day.

Suppose, you have an ISP that provides you with native ipv6 connectivity. This means, you have been assigned a globally routeable IP version 6 address -yay!! However, this comes with a cost: You don’t have a globally routeable IP version 4 address, not even a dynamic one. And this is still necessary, if you want to be able to reach your service, e.g. from cell phone networks.
