Můj nový počítač 
1 2025.03.15-Cobra2025
Skype skončil (teda má skončit v květnu), Firefox expiroval a je nutný nový kvůli certifikátům, takže důvod pro nový začátek. (Předchozí viz Cobra2024 který se ale nějak neujal a stejně jsem používal SkypeSR).
Vyprázdnil jsem devRHM - partition 14 protože tam nic nebylo a RHM je dávno passé.
