**Erik St. Martin:** I also liked Dave Cheney's top tip: traveling with circuit boards and loose wires, they go in your checked baggage. A lot of us were traveling with hardware for Hack Day.
**Francesc Campoy:** Yeah, what could go wrong with that? \[laughter\]
**Erik St. Martin:** I was really worried none of it was gonna show up. Like, I'd get the bag and it'd be mostly empty. Because almost the entire bag that I had checked had tons of logic analyzers and bus pirates and raspberry pies and loose wires and sensors and stuff. I was like, "This is not gonna end well."
**Brian Ketelsen:** Yeah, you got the big flag for extra screening.
**Erik St. Martin:** Yeah, that's why I put Brian's name on that luggage.
**Brian Ketelsen:** \[luggage\] Checked bag for Brian Ketelsen, right here. Alright, let's do \#FreeSoftwareFriday, we're running out of time.
**Erik St. Martin:** Cool. You wanna go first, Brian?
**Brian Ketelsen:** You bet. So I'll briefly explain again, \#FreeSoftwareFriday is just our place to give a shout out to open source projects and/or their maintainers for things that we use frequently and that we love. Today I'd like to give a shout out to - this is kind of a cheat, but I used it a lot this week... So...
**Erik St. Martin:** How about you, Carlisia?
**Carlisia Thompson:** On the topic of Brasil, there's this open source project called Tsuru. It's a Platform as a Service, open source of course. It was put out by Globo.com. Globo is this huge media company in Brasil. It's a project that came out of Brasil, and most of the maintainers if not all are Brazilian develop...
**Erik St. Martin:** And apparently all written in Go.
**Brian Ketelsen:** It is, yeah.
**Carlisia Thompson:** Yeah, of course.
**Brian Ketelsen:** It's been around for two years, too. It's been out for a long time. It's very stable now.
**Carlisia Thompson:** I actually met Andrews Medina and other developers at GopherCon.
**Brian Ketelsen:** That's awesome.
**Erik St. Martin:** Francesc, do you have a project that you wanna give a shout out to? Feel free to say no, we're blindsiding you here.
**Francesc Campoy:** Does it need to be written in Go?
**Erik St. Martin:** It does not need to be written in Go.
**Francesc Campoy:** \[01:00:00.27\] Then I think I'm gonna go with something that is actually for real but we use regularly for the Google Cloud Platform Podcast, Audacity.
**Erik St. Martin:** Yeah, that is a good one.
**Brian Ketelsen:** Nice.
**Francesc Campoy:** Open source digital audio editor, and it is great. It works so well. It makes our podcast sound way better, without knowing really what we're doing.
**Brian Ketelsen:** Good call.
**Erik St. Martin:** I don't know whether Adam and the Changelog crew is still using that behind the scenes, but I know they used to use Audacity a lot, so we don't even have to give them a link to put on Twitter; I'm pretty sure he knows that one.
**Brian Ketelsen:** Do we have the best deal or what? We just get to talk and somebody else does all of the post production work, and the website... I love this plan.
**Erik St. Martin:** Right? So mine - actually, I recently started using it again, and I used to be a big proponent of it - is Direnv, direnv.net. It's written in Go, and it's a cool little program you run in your shell so that basically when you cd into a directory it looks for a .envrc file and then you can basically...
**Brian Ketelsen:** Yeah, Direnv is especially nice if you want to have a custom Go path per project; you just drop that .envrc file in there that changes your Go path. It's kind of custom-built for that, purpose-built. Very nice.
**Erik St. Martin:** And I think that is it. I wanna thank everybody for coming on the show, I wanna thank all the listeners who are listening live right now and hackling us from the Slack channel, everybody who will be listening... Definitely refer any Go programmers or people who are interested in the Go language to ...
**Brian Ketelsen:** Thank you, Francesc!
**Francesc Campoy:** Thank you for having me!
**Carlisia Thompson:** Thank you!
**Erik St. Martin:** If you're not subscribed, we are on iTunes and Play Store. You can subscribe at GoTime.fm. Big shout out to our sponsors for the show today, Linode and Equinox.io.
If you have something you would like to discuss or suggestions for guests to come on the show, github.com/GoTimFM/ping. I think that's it. It's a lot to cover, but I think I got it all.
**Brian Ketelsen:** You did well, Erik. Good job!
**Carlisia Thompson:** This was great, thanks! Bye!
**Brian Ketelsen:** Bye-bye. Thank you.
**Francesc Campoy:** Bye.
**Erik St. Martin:** Bye.
