I clicked that link expecting Linus Torvalds and was very confused. The mononym "Linus" is already taken :-) It would be very exciting to see Linus Torvalds playing with giant amounts of RAM but sadly he doesn't seem to make a lot of videos like that.
If you're talking operating systems, it's Linus Torvalds. If you're talking tech videos, it's Linus Sebastian. Linus Media Group gets a lot of the cool hardware first and often makes a point of getting some unofficially to mess with it in ways they're not supposed to.
