YouTube Alternatives for Programming Tutorials and Conferences Videos?

I'm trying to reduce addictive apps and websites from life. I was just wondering if there are any real YouTube alternative for programming tutorials and conference talks.

I researched and found the following:

1. University ( university.company.com \ product centric tutorials offered by projects/companies like HasiCorp, MongoDB, SkyllaDB etc ) 2. Read Docs. 3. Using New Pipe ( Privacy focused Android Client for YouTube and create a custom local subscription list ).

Do you guys know any viable alternatives ?
