**Mat Ryer:** Yeah, you feel a bit bad.
**Erik St. Martin:** I always appreciate it when they do.
**Mat Ryer:** Yeah.
**Erik St. Martin:** Alright, so anybody have any other projects that they've come across that are really interesting? I know there's one that I came across that I'm kind of interested with Kelsey being so active in the Kubernetes world, to see what his thoughts are. Have you seen the Fission.io, Kelsey?
**Kelsey Hightower:** Yes, I've seen Fission.io... I have lots of opinions. For those of you that don't know what Fission.io is, it's an attempt to bring the serverless -- really the functions as a service paradigm to Kubernetes. Kubernetes is this application framework, it lets you deploy your containers and describe ...
When I take a step back, to me what makes the whole serverless or functionless stuff worth doing is when you have a robust event system. Cloud functions in Google, Lambda in AWS - what makes those things powerful is the fact that you can watch an S3 bucket or you can respond to a message queue, or on the Google side yo...
So I'm kind of on the fence with serverless as just a different way to program, but I am on board with this idea of providing a rich set of events from various sources - email, HTTP, events from the platform itself - and giving people an easy way to process it. I think of this as like a cron job on steroids... Being ab...
**Erik St. Martin:** I'm with you there on the serverless... I'm still on the fence. How about you, Mat? Do you have any experience with serverless?
**Mat Ryer:** Well, as I said, I use App Engine quite extensively... The kind of projects I work on, having this serverless, just being able to push code and it's running and it's available - that's massive for me. That makes all the difference, actually. I would have to be an expert or know an expert, or at least some...
**Kelsey Hightower:** Yeah, for those that didn't pick up on that, Mat brought out a really great point - what we call serverless to me (and I think Mat agrees here) is not about functions as a service; I think it's about being able to focus on the application, and I think some platform-as-a-service such as AppEngine, ...
**Erik St. Martin:** \[56:17\] That's a really good point. I know we're basically kind of running out of time here and I know Kelsey has a hard stop... Did anybody have anything they wanted to mention for \#FreeSoftwareFriday before we kind of wrap things up?
**Kelsey Hightower:** I do. I'll give a shoutout to the CNCF. They're doing a good job of extending what the Linux Foundation has done for many years for the Linux project. I think linkerd just joined gRPC; they're also housing Kubernetes, fluidd and Prometheus. And they do a really good job of taking what they call 't...
**Erik St. Martin:** Yeah, I agree. They're doing awesome things and building a collection of things for cloud-native. OpenTracing is another one that they handle. Mat, how about you? Do you have anybody you wanna give a shoutout to? This does not have to be a Go project. This is our time to recognize people or project...
**Mat Ryer:** Well, GitHub is something that I think is actually awesome; I think we take it for granted a lot, but it probably does get the recognition it deserves, so I don't think that applies. I like Visual Studio Code, I've been trying that out recently... Although it still seems to be burning my machine down with...
**Erik St. Martin:** Yeah, people have really been loving the Visual Studio Code for Go recently. I'll name off two projects. Over the holiday break I started playing with software-defined radio a little bit. It's still very early into that and I didn't realize just how much goes into that, but two tools that have been...
The other one is GNU Radio. I didn't realize just how much you could do with that. And there's a GNU Radio Companion (I think that's what it's called) that goes along with it and you kind of assemble a workflow for the radio frequency to go through. Super cool tools, they do a ton.
**Carlisia Thompson:** Can I give a shoutout to something? I just realized that it's timely, because it's gonna happen next Wednesday. I just realized, it's just entering my radar that Gopher Academy has a big marker channel, which is the same as the Go Remote Meetup, that separate channel with separate events. And nex...
**Erik St. Martin:** \[01:00:07.14\] Yeah, definitely... If you've never pushed a PR to any open source project, you should attend that. I think it's important for people to do and to give back.
**Mat Ryer:** The Go newsletter - and this isn't just because I happen to be at the top of it this week... I love getting the Go Weekly newsletter. You can google that, because anyone that doesn't have it should get it. That is a great way to learn about various projects and happenings in and around the Go community. I...
**Carlisia Thompson:** Yeah, we do, too.
**Erik St. Martin:** So I think with that we are out of time, and I wanna thank everybody for being here. Huge thank you to Kelsey for stepping in for Brian, definitely a huge thank you for Mat for coming on and for Gopherize Me... All the people I follow on Twitter are now cool-looking gophers. \[laughter\]
**Mat Ryer:** Yeah, just one last thing, this is quite interesting... I found an API basically for this merchandise website, and you basically just link to them and put an image URL as part of the ingoing URL (it's a query parameter) and then you can shop for merchandise that contains that image. They'll put it on a mu...
**Erik St. Martin:** Oh, nice. I want my own personal gopher sticker. \[laughter\]
**Mat Ryer:** Yeah, at what point do we start to hate these little gophers? That's gonna happen at some point, isn't it? When they take over...
**Erik St. Martin:** They're taking over the world...
**Mat Ryer:** Well, there's already more possible combinations... They're enough for everyone on the planet to have almost like ten each, I think. It's insane, the number of actual different combinations of gophers on Gopherize Me.
**Erik St. Martin:** Oh, wow... So huge thank you to all of our listeners and to our sponsors, Backtrace and Ardan Labs' Ultimate Go Series. Definitely share this show with friends and co-workers who you think might be interested. You can subscribe by going to GoTime.fm. Follow us on Twitter, we are @GoTimeFM and if yo...
**Carlisia Thompson:** Bye!
**Kelsey Hightower:** Goodbye!
**Mat Ryer:** Goodbye, thanks for having me!
