Don’t downvote this guy. He’s mostly right. Creative works have copyright protections from the moment they are created. The relevant question is indeed if they have the relevant permissions for their use, not wether it had protections in the first place.
Maybe some surveillance camera footage is not sufficiently creative to get protections, but that’s hardly going to be good for machine reinforcement learning.
Yeah of course! Once I went on a buying spree of used WNDR3700. They were so cheap and I won a few too many bids at once.
I gave one to a flatmate when we lived together as students and he took it with when he moved out. Put one in the office room of my current flatmate and still have one or two in reserve. I usually take one with me to LAN-parties.
Before that I once used DD-WRT on a WRT54GL. It also wasn’t bad from what I remember.
