   The fundamental reason that we started on this track is the need to get off of Python 2, which has reached EOL and from which the community is moving away. Because of APIs we're using and such, it's not easy to switch to Python 3.

   For reasons I touch on in our blog post[1], porting to Python 3 would still be a huge amount of work (not quite as large as the port to Go, but still very large and without other benefits we get from Go). [1]: http://engineering.

    Video playing is mostly handled by YouTube. Features which use a lot of CPU are tracking learner progress, managing classrooms, and the like. These features are really important right now as teachers have moved classes online. We are in the

    Sorry to hear that. AFAIK, we just use Stripe, which is pretty standard.

    I don't know what the range is, or if we post those publicly. What I do know is that we pay competitively, but we obviously don't have stock so there is no stock component to the pay. Someone whose primary goal is to make money wo

    Hi! There are no stupid questions. I wanted to make sure I had the right answer, so I had actually just spoken with my manager about this yesterday. As of now, in order to ensure legal compliance, we work through another company for hiring

    I did speak to my manager about hiring from Europe. She said that in order for us to ensure legal compliance, we work through a particular company. Doing so covers our legal bases, but also means it's very expensive for us to hire else

    Thanks! We are fortunate to have good name recognition. One thing we've noticed is that a lot of folks don't know that we're a non-profit, so we try to make that point as much as we can. Edit to add: speaking for myself and m
