So I recently had a conversation with some who though Linus Torvalds (kernel) and Linus Sebastian (Linus Tech Tips) was the same person.
That was a pretty funny and confusing conversation.
I thought he branched out to tech tips as a way of making extra money. Never seen the tech tips myself and with the controversy not too long ago probably never will.
I've only ever heard of torvalds because of pages like this one and since I don't watch LTT videos often, I've only ever heard his first name connected with the channel.
As an entertainment show about tech, it's a pretty decent show to watch, I wouldn't use it to base my decisions on, but if you want to hear someone talk about tech stuff in a somewhat entertaining way I'd say give them ago, Linus can be a bit much sometimes but the rest of the crew are alright.
The trick is to listen to the pronunciation. Linus of LTT pronounces it as Linus, while Linus of Torvalds uses either Linus or Linus, but he doesn't mind if people call him Linus.
