**Ron Evans:** Well, funny you should mention that... There's really a few things that can make the big difference that currently are either completely lacking or are in the very early stage and need a lot more community involvement. The answer to everything is more community involvement, naturally. The first one is Bl... |
The best work that's been done in this space has been by Roy Lee with the current lab's BLE package. It is amazing how much work Roy has done pretty much almost entirely on his own. I mean, a few of us have helped out a little, little bit. He's shouldering the technical debt for building out the entire BLE stack for Go... |
Another one is running Golang on real-time operating systems like Zephyr or Mbed or FreeRTOS. There's no reason why we shouldn't be able to compile Golang and target it against an RTOS the same way that we're targeting Windows or OS 10 or MIPS (Nine). It's really a matter of somebody dedicating the time to... And there... |
And having some support for OpenCV, which is a computer vision package... You know, computer vision and machine learning - the other two pillars of the instrumented real world, right? We need the things that are the sensors giving us the data, and then we need these other software-based capabilities to analyze that dat... |
Our role the way that we see it as members of the Gobot team, we're sort of the stewards of the de-facto low-level hardware interfaces for Go at this point. There have been a couple of movements, but whether or not this should be actually part of Go itself is very arguable, just because keeping Go very light and minima... |
\[20:00\] What I do have an opinion about is more if we as a community can sort of rally around creating a shared set of low-level hardware interfaces, to make it easier for implementers. We can then not just have Gobot, but potentially other projects that could utilize those same interfaces and share ideas. You know, ... |
It always just comes back down to "Let's share ideas and see what happens." But there's a lot of exciting stuff going on as far as hardware-related activity. First of all, I made a list of some -- just even this week. So I'm Los Angeles this week for the SCALE 15x conference. [SCALE](https://www.socallinuxexpo.org/scal... |
**Brian Ketelsen:** Wow. |
**Ron Evans:** Really fantastic conference. They had to move from their original home at the LAX Hilton because of the fire marshal, so they're now at the Pasadena Convention Center, it's taking place this weekend. If you're in the L.A. area, I really recommend... |
There's lots of amazing talks, Canonical is running UbuCon, which is Ubuntu-focused on the first two days of the conference. Saturday there is SCALE: The Next Generation, which is a day conference track by and for kids. So it's kids giving the talks and attending them, and a bunch of workshops and other activities, and... |
But this week has been really exciting in the hardware world. The Raspberry Pi Zero W, which is the new Raspberry Pi Zero with built-in Bluetooth and Wi-Fi... |
**Brian Ketelsen:** Do you know what the W stands for, Ron? |
**Ron Evans:** Wireless. |
**Brian Ketelsen:** Want. |
**Ron Evans:** Oh, yeah... I ordered mine by violating air flight rules and actually doing it on my mobile phone while waiting for take-off on an international flight, and just managed to get my payment info in right before the flight attendants forcibly took the phone. |
**Brian Ketelsen:** Nice. |
**Ron Evans:** Yeah, that's how dedicated I am, my friends. \[laughs\] But yeah, it's really exciting... For 10 USD, it's a Raspberry Pi with all the trimmings AND the built-in wireless. I'm very excited. I've been a big fan of Raspberry Pi since I had -- I was fortunate enough to actually have the first Raspberry Pi i... |
They've had tremendous community buildup around it. There's all kinds of interesting software that runs on the Raspberry Pi. Gobot runs really well, especially with Go 1.8's improvements substantially as far as Go's performance on ARM... Somewhat less so on x86 just the performance was already quite good. |
**Brian Ketelsen:** \[23:54\] Well, speaking of the Raspberry Pi, there's some metrics... You were mentioning adoption metrics earlier. I have some metrics that I recorded that I want to share with you. Since putting Gobot on my Raspberry Pi, I have used Gobot to control the cook of 68 racks of ribs, 17 briskets, 5 pri... |
**Ron Evans:** Alright, I'm hungry. |
**Erik St. Martin:** He's actually keeping count. \[laughs\] |
**Brian Ketelsen:** And that's adoption. Those are metrics that matter, Ron. |
**Ron Evans:** You know, this is the true quantified self. |
**Erik St. Martin:** So I know that we can probably go pretty deep especially into the barbecue stuff - it's something Brian and I love. But before we do that, let's take a quick sponsor break. Our first sponsor for today is Backtrace. |
**Break:** \[24:43\] |
**Erik St. Martin:** Alright, we're back, talking with Ron Evans about Gobot, and important statistics about Brian's grilling with Go. During the break you were talking about the puns with Go... I really wanna see an Energizer bunny powered by Gobot, so we can really say it keeps going and goin... |
**Ron Evans:** It's so funny... I don't wanna take away any surprises, but there might be some interesting new toys that we will be bringing to Hardware Hack Day at GopherCon. |
**Brian Ketelsen:** Oh man, what a tease... |
**Ron Evans:** Yeah, pretty much... |
**Erik St. Martin:** I really wanna retire from organizing just so I can attend... |
**Brian Ketelsen:** I know... |
**Carlisia Thompson:** Okay, give us a hint. |
**Ron Evans:** So I finally got to meet [Renée French](https://twitter.com/reneefrench) in real life at the last GopherCon, and obviously I'm a big admirer of the gopher, and the talk about the standards for appropriate gopherism, which I know is a topic that has concerned all of us at one time or another... So I've ne... |
**Brian Ketelsen:** Wow... This sounds huge. |
**Carlisia Thompson:** Okay, sounds very good. |
**Ron Evans:** It's relatively small, and yet big at the same time. |
**Brian Ketelsen:** Gobot controlled gophers. I'm calling it now. |
**Erik St. Martin:** That's be so awesome. |
**Ron Evans:** I can neither confirm or deny any rumors... |
**Brian Ketelsen:** Oh my god, my email is blowing up. Ticket sales are going through the roof for GopherCon, you'd better get your tickets now. |
**Erik St. Martin:** Speaking of which, speakers were announced... If you are listening live - or even by the time you hear this show - if you have not looked, definitely go look at the speakers. We're kind of jumping ahead, but yeah... |
**Carlisia Thompson:** \[laughs\] You are thoroughly jumping ahead, but that's cool... \[laughter\] |
**Erik St. Martin:** \[27:47\] One cool thing to talk about when we talk about Gobot and stuff - and even bringing up Brian's barbecue thing - is a lot of people feel like hardware is unapproachable, and Arduino was a big kick back into the maker scene, and people are able to do a lot of things with hardware more easil... |
**Brian Ketelsen:** I don't know, I'm having a hard time struggling with the idea that that segue sounded a lot like, "Brian's an idiot, and even he can use Gobot on Raspberry Pi." \[laughter\] But the truth of it is, I was gonna interject and say I'm an idiot, and even I can use Gobot on a Raspberry Pi, so I'm not gon... |
**Ron Evans:** By the way, very elegant PID-based implementation. Kudos to you, sir. |
**Brian Ketelsen:** Thank you so much. I sat my kids down at the dinner table while we were doing it and I said, "Don't let anybody tell you you'll never use math after college, because there are important things in life, like barbecues, that might require calculus. So pay attention." |
**Ron Evans:** Oh, absolutely. And just to riff on the same idea, the idea that the difficulty of a thing is equal to the goodness of a thing, to the benefit, to the value of the thing is only because of scarcity. Like, if relatively few people know how to do a thing, then it's more valuable. But we live in the open so... |
It's like having a book about something that you haven't read, but you keep on the shelf. It's not the same thing as actually possessing and assimilating that knowledge and doing something with it. It's a poor shadow. |
**Brian Ketelsen:** Couldn't agree more with that. |
**Ron Evans:** So crossing this barrier between -- you know, a lot of people look at hardware and think, "Oh, I could never do that." Well, the funny part is if you talk to electrical engineers, they say "Oh, software - yeah, it's really hard." \[laughs\] And I've seen this a bunch of times with lego-first robotics tea... |
