For anybody who didn't go to community day or didn't go to GopherCon at all, on community day, which is the day after the talks, we basically have these rooms set up (that we were just describing) - that contributor room, GoBot room... All of these things where you can collaborate with people, but there's also kind of ...
**Brian Ketelsen:** It was crazy.
**Erik St. Martin:** I'm really pleased with the number of people who are kind of seeing community day. We had way more people the first year stay than I think we anticipated. It started off as just sort of a "We know most people are probably flying out the day after the talks, and everybody flies out at different time...
**Brian Ketelsen:** I saw at least two, maybe three really big projects that got a lot of lift on community day. The first one was [Dep](https://github.com/golang/dep). I know [Sam Boyer](https://twitter.com/sdboyer) had at least three tables worth of people, all contributing. I think he started the day hoping that he ...
I know Kris Nova had a [Kubicorn](https://github.com/kubicorn/kubicorn) table, and I swear to God she looked like a cult leader over there, because they were all just watching her with rapt attention. I'm not sure what kind of things she was telling them, but I know Kubicorn had a pretty nice release, too. So the cult ...
**Erik St. Martin:** \[28:03\] So how about favorite talks? Or at least ones that you heard good feedback on that maybe you didn't catch yourself. I know that I often don't get to watch many of the talks (if any) until the video is released, and depending on my work schedule is how fast I consume them.
I can start off... One that seemed to get a very, very good reception - and I actually happened to watch this on YouTube - was just recently a guest of our show, which was [Kavya Joshi](https://twitter.com/kavya719), who did the [Understanding Channels](https://www.youtube.com/watch?v=KBZlN0izeiY0). If you haven't seen...
She walks through the implementation of channels. This isn't "How do you use them?" but "How do they work under the hood?" and there is a bit of how the runtime works too, with regard to scheduling goroutines that have blocking sends and receives on them.
**Brian Ketelsen:** Yeah, it was a super geeky talk, and it was low-level enough that I think everybody learned something. My favorite part of the talk was at the end, when everybody mobbed her at the stage from the Go Team. \[laughter\] I turned around to Erik and I said "Somebody's getting a job offer soon..." \[laug...
I like [Edward Muller's](https://twitter.com/freeformz) [talk on Go Anti-Patterns](https://www.youtube.com/watch?v=ltqV6pDKZD8); that was a really good talk. He hit the nail on the head on a ton of different things that I've been teaching for the last couple years and taught me several that I've been abusing for the la...
**Erik St. Martin:** That room was busting out the seams.
**Brian Ketelsen:** It was, it was really busy.
**Erik St. Martin:** It's one I haven't caught yet. I haven't been able to watch that video yet, but it definitely seemed like a really popular talk.
**Carlisia Thompson:** Yeah, everybody should watch that talk, especially beginners... Especially! Please do.
**Erik St. Martin:** And I don't think that we could leave out Russ Cox talking about [the future of Go](https://www.youtube.com/watch?v=0Zbh_vmAKvk), where I think people about dropped dead when he mentioned that it's time to start thinking about Go 2.
**Brian Ketelsen:** Yeah, but -- alright, so I love the Go team and I love Russ, but man, that was the biggest cop-out talk ever. Complete cop-out. So you put on the schedule "The Future of Go", and start letting rumors slide, "We're gonna talk about Go 2.0. This is amazing." Yeah, we're gonna talk about talking about ...
**Erik St. Martin:** I don't know that I agree.
**Brian Ketelsen:** No, no, don't even try to defend him. Don't do it.
**Carlisia Thompson:** Okay, explain yourself better, I'm not getting -- I don't wanna interpret what you're saying; just spit it out.
**Brian Ketelsen:** I'm just teasing Russ. I really have nothing bad to say about it at all, but I was just saying that we were teased by the idea that Go 2.0 was coming, and really it was just a talk about how we're go about talking about Go 2.0.
**Erik St. Martin:** I think that the Go team and everything has been very much "We're gonna focus on implementation and bettering that and improving compile times and speed and all that stuff, and we're not gonna work on changing the language." So I think that it still is a very exciting thing that collectively they a...
But I also think that one of the big takeaways from that talk was soliciting for experience reports, because he walks through kind of the history of how they solve problems and things like that, and they want to see concrete examples of where these things are problems. An example was _generics_ - sometimes they don't h...
\[32:16\] I think that that was probably the biggest takeaway - if you want to help shape what Go 2.0 ultimately becomes, you should make it a point to contribute that feedback.
**Carlisia Thompson:** I was going to say the same thing Erik just said, just not as articulate. But I do wanna re-emphasize that even though it was a talk about "Let's talk about talking about Go 2.0", I think it was very valuable... Because people communicate -- I mean, it's just normal... We're not very effective an...
He was very specifically saying, "Submit your problem. Submit a use case for your problem." I was reading Reddit, and there were so many people saying, after that talk -- I don't know if they watched it or not, or read about it or not, because there was also a [blog post](https://blog.golang.org/toward-go2) that goes w...
**Brian Ketelsen:** If they had named the talk -- I'm sorry, I didn't mean to cut you off. Please finish.
**Carlisia Thompson:** No, I was just gonna repeat myself; thank you for cutting me off.
**Brian Ketelsen:** \[laughs\] If he had named the talk "How To Communicate Or Build Consensus On The Forward Movement Of A Project", then I would give it 12 out of 10. But he named it The Future Of Go, so I say it's a 5 out of 10, because we didn't talk about Go's future, we talked about communicating and building sci...
**Erik St. Martin:** We talked about how we will influence the future of Go, and that there will be a future of Go.
**Brian Ketelsen:** Exactly, which again, is an incredibly valuable talk, but we totally got click baited on the title. "Ten people got together in a room and built Go 2.0. Click here to see what happens next!"
**Erik St. Martin:** So one cool fact that -- I'm gonna totally ignore Brian right now... \[laughs\]
**Brian Ketelsen:** This is new?
**Erik St. Martin:** One cool fact that came out of that though was -- I forget where the stat came from, but I know that they had estimated somewhere between 500,000 and a million Go programmers in the world, which seems astronomical at this point.
**Brian Ketelsen:** I can't remember where the stats came from either, but you're ignoring me, so I won't answer anyway.
**Erik St. Martin:** \[laughs\] So other talks...
**Brian Ketelsen:** Oh, you know who nailed one - [Liz Rice](https://twitter.com/lizrice).
**Erik St. Martin:** Yes....
**Brian Ketelsen:** [A Go Programmer's Guide To Syscalls](https://www.youtube.com/watch?v=01w7viEZzXQ). That was so cool. Great talk.
**Erik St. Martin:** She basically started the talk out talking about how in prior talks she mentioned system calls and she wanted to kind of make sure she knew what she was referring to when talking about them, so... She wrote a talk explaining how system calls work to people, and that's actually really great if you'r...
**Brian Ketelsen:** \[36:14\] Yeah, Brian Downs in Slack said he could listen to Liz talk about anything, and I totally agree... This is maybe the third time I've seen her talk, and she just has such a fantastic delivery, she's so eloquent, and she knows the materials so well. Between her and Jess Frazelle, I have 100%...
**Carlisia Thompson:** I was gonna say the same thing... I was going to say I haven't seen her talk, but I don't even care what it was about, because I've seen her talks before -- the talk that she gave at Golang UK last year... She's so great, I will watch anything she talks about.
**Erik St. Martin:** Yeah, and if you didn't see it, the [talk](https://www.youtube.com/watch?v=HPuvDm8IC-4) that Carlisia's referring to from [Golang UK](https://www.golanguk.com/) was she implemented containers in Go.
**Carlisia Thompson:** She did it live. It was very badass.
**Erik St. Martin:** It was super cool, and I love that it makes the containers seem less magic. Because I think a lot of people see them as just kind of this -- it's kind of like a virtual machine; you don't implement your own virtual machine, or virtualization software... But it kind of really breaks it down and you ...
Also on the deep technical end was Keith Randall; he came back and talked about SSA.
**Brian Ketelsen:** Oh, [the SSA talk](https://www.youtube.com/watch?v=uTMvKVma5ms)... That was a good one.
**Erik St. Martin:** Yeah, which also, if you love Assembly...
**Brian Ketelsen:** Yeah, which, to be honest, I still don't understand, but it was a great talk.
**Carlisia Thompson:** I was gonna say exactly the same thing... \[laugh\]
**Brian Ketelsen:** Hand wavy magic, something, something, compiler... Look!
