    1:02 – Chuck: Hello! The panel today is Eric, Dave, Nate, and myself! Our guest is Vlad!

    1:30 – Guest: My name is Vladimir, but people call me Vlad. I have been writing Ruby since 2013 for about 4.5 years. Before that I was a PHP, JavaScript developer among other languages. I am mostly Erlang and Ruby now.

    2:29 – Panel asks Vlad a question.

    3:29 – Guest: Yeah something like that. I call it a different server b/c we still use the code base but we do not do anything related to web sockets and connections.

    4:20 – Panel: If you wanted to take a normal action cables setup what steps would you have to go through to convert that over to also use the anycable server?

    5:21 – Guest answers the question.

    7:31 – Chuck: This sounds complicated and a bit of work. When I look at this I think: I have a tiny app is it worth it? When does it become worth it?

    7:52 – Guest: Definitely not for the tiny app.

    8:50 – Panel: You use it when it makes sense. Overcomplicating your infrastructure doesn’t make sense.

    9:27 – Guest: That’s the idea.

    10:28 – Panel.

    11:05 – Guest: The question really is how many connections you have and how long-lived they are?

    13:09 – Panel: If I move my project over to anycable how much new code am I going to have to write?

    13:28 – Guest answers the question.

    15:52 – Panel: What’s the update been like for anycable and how many users use anycable?

    16:05 – Guest: I really don’t have statistics. I hear people at conferences say that they use anycable, but no real statistics right now. I would like to know these numbers, but no idea.

    16:30 – Panel: …is that the time to consider using anycable?

    17:05 – Guest: That’s a good point to make.

    18:44 – Panel: How is the initial handshake time with anycable? Is there any difference with anycable in that sense?

    19:05 – Guest answers the question.

    22:49 – Chuck: Can you define a couple of terms for me? I am hearing terms like: concurrency and real time and others?

    23:00 – Guest: Good point. What is real time?

    The guest continues to define these terms.

    28:10 – Fresh Books!

    29:10 – Chuck: Ruby 3 is supposed to solve some of these problems. Can you talk about some of those?

    29:46 – Guest: Interesting question and I’ve been asked about this before.

    35:14 – Panel: Did you say there was some activity around trying to reduce the memory consumption for thread?

    35:25 – Guest answers the question.

    36:14 – Panel: Vlad, you are spread from backend to fronted and you’ve mentioned Phoenix Live Vue. Can I pick your brain about it?

    36:39 – Guest answers the question.

    38:48 – Panel: It seems like one of the core tenants is empowering small teams to compete with larger teams. I have high hopes to keep small teams competitive.

    39:50 – Guest: Yes, that’s the idea of Rails and Ruby itself to build something and try something and perhaps fail.

    40:57 – Panelist mentions Erlang, anycable, and concurrency.

    41:14 – Guest: We are working on administration functionality and we want to build something fast.

    44:40 – Panel: That’s the interesting thing about turbo links cause I think it was a marketing fail. You have to invest time to learn how to use it and how to use it properly.

    45:44 – Guest: I don’t have a good guide for turbo links.

    46:00 – Chuck: Anything else we want to talk about?

    46:10 – Guest: Two more things I want to mention.
