**Brian Ketelsen:** That was my troll for the day, right? \[laughter\]
**Erik St. Martin:** Well, if it's a good segue, go ahead.
**Aaron Schlesinger:** Alright... Well, I wanted to mention a library by Sam Boyer called GPS. It is a library that basically you import into your code; it's about ten lines of code, and you can get the entire dependency tree for any package, in a Go data structure. On top of it, it's being brought into the Glide proje...
**Erik St. Martin:** That kind of reminds me... There was another tool that I saw come out - I can't remember where it was or who mentioned it, but it basically does the whole visualization of your dependency tree for your project. For the life of me, I can't remember what the project name was, but I will link to it in...
**Aaron Schlesinger:** Nice.
**Erik St. Martin:** Wait, somebody in the GoTime FM Slack channel just mentioned it.
**Brian Ketelsen:** Ask, and you shall receive.
**Erik St. Martin:** Right, so it's called goviz. I don't even know how to pronounce the GitHub username.
**Brian Ketelsen:** We'll just put that one in the show notes.
**Erik St. Martin:** And link to it on Twitter. But yeah, that was super cool, too. So for my \#FreeSoftwareFriday, I'm gonna give a shout out to Miek Gieben for CoreDNS.
**Brian Ketelsen:** Whoow!
**Erik St. Martin:** Yeah... That's such a cool project from the Kubernetes world. You're familiar with SkyDNS, right?
**Aaron Schlesinger:** I am... Is that a question for me?
**Erik St. Martin:** Yes, so SkyDNS has been around and connected to Kubernetes for a couple of years now, but Mieke actually completely rewrote it and worked with Matt Holt on refactoring Caddy, so that Caddy could be more pluggable, the way the configuration works, the middlewares and stuff. So CoreDNS basically can ...
**Aaron Schlesinger:** That whole community around Caddy is just awesome to me. I love those people.
**Brian Ketelsen:** Word! Big time! I use Caddy for everything, for two years now. I don't regret a minute of it.
**Erik St. Martin:** Brian accused Matt when he was on the show of being the nicest person in the Go community... \[laughter\]
**Brian Ketelsen:** I still think it's true.
**Aaron Schlesinger:** He is!
**Brian Ketelsen:** Yeah, he's awesome.
**Aaron Schlesinger:** \[56:08\] He DM-ed me on Slack when he first started Caddy. He said, "Do you think Caddy is an okay name to use?" I said, "Well, what does it do?" He said, "It's a better web server." I said, "I don't care what you name it, build that! \[laughter\] People will use that."
**Brian Ketelsen:** You can call it Bob, we don't care.
**Erik St. Martin:** Yeah, call it Thing!
**Aaron Schlesinger:** Thing, yeah. I love that guy, too. That whole community that he's built around Caddy is one of the best in software.
**Erik St. Martin:** Yeah, just tying in ACME and Let's Encrypt...
**Aaron Schlesinger:** Focusing on this concept of like security by default, with no extra work, no extra configuration, that's what we need. That's perfect.
**Erik St. Martin:** I'm really interested to see how many other people spawn projects similar to CoreDNS using the Caddy libraries as the building blocks to build their own tools on top of.
**Brian Ketelsen:** Yeah, this refactor really made it amazing to do that, so why not? We need a blog post.
**Erik St. Martin:** Somebody needs to come up with a new idea.
**Carlisia Thompson:** We did so many blog posts out of this episode, it's not even funny.
**Brian Ketelsen:** You know what we need - a 5-minute video about it.
**Aaron Schlesinger:** Actually, I'm way ahead of you. I'm not doing it with Caddy, I'm doing the ground-up thing with Lego.
**Brian Ketelsen:** Oh, nice!
**Aaron Schlesinger:** But Caddy might be a good one to follow up with.
**Brian Ketelsen:** I've decided I'm not gonna use Lego for anything. I'm not gonna manage that... I just reverse proxy everything behind Caddy and smile. \[laughter\]
**Aaron Schlesinger:** That's not a bad idea, actually.
**Brian Ketelsen:** I do, I'm not kidding. Just... Why? Why do it?
**Erik St. Martin:** I haven't even set Caddy up as a reverse proxy yet.
**Brian Ketelsen:** Oh, it's so freakin' easy.
**Erik St. Martin:** Most of my stuff is kind of hidden away right now. I'm working on stuff that just interacts with Kubernetes libraries and stuff like that. It's not kind of exposed. So I think now we are actually out of time. Anybody have any closing notes before we call this thing a wrap?
**Brian Ketelsen:** No.
**Carlisia Thompson:** No.
**Erik St. Martin:** Alright then. I wanna thank everybody for being on the show, especially thank you to Aaron for coming on this show. Everybody definitely check out his Go In 5 Minutes videos; I think it's gonna be really interesting to see all the new ones that come out from this show. I think we've had a lot of go...
**Brian Ketelsen:** Goodbye!
**Carlisia Thompson:** Thank you Aaron, and goodbye everybody!
**Aaron Schlesinger:** Goodbye, everyone!
