Summary

Everyone has used programs that talk to a server: Uber, podcast apps, etc.. Most people also know about peer-to-peer applications such as bittorrent, but did you know that video chat programs such as Skype and Google Hangouts are also peer-to-peer? You can even write your own peer-to-peer applications to communicate or share information without the need for a server to relay everything. In this episode, we sit down with Sean DuBois, creator of Pion, to talk about WebRTC: a specification and set of tools for peer-to-peer communication over the internet. We also discuss Pion, an implementation of WebRTC that you can embed in almost any program you write. Happy Hacking!

0:00.0	Programming Throwdown, Episode 95, WebRTC with Sean Dubois.
0:20.0	Take it away, Jason.
0:21.9	Hey, everybody. We have Sean here on the show, and we're going to be talking a lot about
0:27.7	WebRTC, which is something many of you might have never even heard of, but it's really
0:32.8	eye-opening. It's kind of a shocking thing to find out. It's kind of opening Pandora's box. And so are you doing, Sean? Would you like to sort of introduce yourself?
0:41.9	Great. Yeah, thanks for having me on. So I am Sean. I work on the Pyon project, which is a go implementation of WebRTC, which is sort of like a nebulous thing. So I guess we'll spend the next hour unpacking.
0:56.0	But yeah, so I work in like the WebRTC space.
1:00.0	I've sort of gone through a bunch of different weird things.
1:03.0	I started out in the VoIP and phone industry, found my way working on PHP, and then sort of
1:10.0	ended up here, and it's been a been a fun ride cool so is
1:13.7	that you worked on the php like interpreter itself or or writing so i was so i was was hired at
1:20.6	etzy and originally i started out doing JavaScript and lamp development and i would they gave me
1:25.7	an opportunity to write c and work on PHP itself.
1:28.3	So I added, I think, visibility operators to class constants and I ported a bunch of extensions from PHP to PHP7, like the ones written in C.
1:38.3	Well, that's amazing. So how do you get started doing something like because it seems like, you know, languages themselves are just
1:46.3	enormous projects. And it seems very difficult to amend the language. Like how do you get started
1:53.5	in that? How do you get your changes approved? How does all that work? So I got really, real lucky.
1:58.8	The company Etsy is they're the ones that really kickstarted my
2:02.0	career. Like that was the first job in the industry that, so I got really lucky with the mentorship
2:08.2	they provided. And I think the easiest thing to do is jump in and make little changes that are
2:13.6	supported by unit tests. It's so easy to get things approved by by open source maintainers. If you can jump in and make a change and the build's green, it's very likely they're going to accept it. So that's how I got lucky. I just went in. And I think the first one was IG binary or something. It was like a compression format. And the nice thing is if I can port it from PHP 5 to 7 and all the test pass,
2:36.1	it just got merged, which made it really easy.
