A page has turned with the demise of CyanogenMod, the alternative to Android beloved by geeks. On Christmas Eve, the team at CyanogenMod posted a message announcing that development of the mobile operating system is coming to an end, due in particular to a reduction in employee numbers and the successive departures of its cofounders. This alternative to Android, which was launched in 2009, was an operating system derived directly from Android, and was easily substitutable for the original.
