My understanding was that these programs don’t rely on YouTube’s API, but rather they are loading the page and scraping it for the relevant video files, comments, and other data. So it’s a little harder to kill them than just shutting down API access. That said, with all the new web DRM crap getting pushed by Google and others, I can’t imagine it will be long before they can detect that you aren’t viewing the page the way they want you to view the page, and then block access in some other form.
My degree was a painful slog, but if you push through it, things do get better on the other side. I’ve got a fulfilling job that makes me happy, and a wife that keeps me from thinking about work more than I should. And those classes that you hate? You’ll likely never need to use them anyway. I’m back at it studying for my PE now. Any idea how to find the characteristic or mantissa?
