**Natalie Pistunovich:** Did I miss the sound?
**Mat Ryer:** Yeah, we heard that sound... Kris, how would you describe it?
**Natalie Pistunovich:** Was it the marshmallows?
**Kris Brandow:** I think it's the sound of us closing Slack so our fire's going away.
**Mat Ryer:** Was it marshmallows? Yeah, it's kind of a spooky sound... Wasn't it, Johnny? How would you describe that, Johnny?
**Johnny Boursiquot:** As silent as your hairline? \[laughter\]
**Mat Ryer:** \[50:13\] I mean, it's getting very poetic, and slightly unusual banter there...
**Johnny Boursiquot:** You asked for it. I mean, you did ask for it.
**Mat Ryer:** Amazing. Yeah. Is it silent because it's so far away? Like, it's in the distance... That's what we mean. Like, it's screaming, but you can't hear it...
**Johnny Boursiquot:** It's too far back?
**Mat Ryer:** Yeah. It's just screaming "Why, dad?! Why?!" You know what I mean? If you know you're going to look like this, don't have kids. If you know you're gonna make kids that look like me, don't have them. That's my advice... But dad didn't listen.
**Johnny Boursiquot:** We're all talking about recessions nowadays, but you've been in one for quite some time, right Matt? \[laughter\]
**Mat Ryer:** Oh, there we go... That was a good one... That was a good one, yeah. Good point. Okay, well... That sound of Johnny talking tells us it's time for... Unpopular Opinions!
**Jingle:** \[51:16\]
**Mat Ryer:** Okay... Who's gonna kick us off with the first popular opinion? Dee! You've been chosen.
**Johnny Boursiquot:** You scared him. He was like, "What?! What happened?! What happened?!" \[laughs\]
**Mat Ryer:** It's just sounds. I promise no one's pushing their hand around the Ouija board to make it spell out about my hairline. I don't want to hear anything from the ghosts about my hairline, Johnny... Right? So don't make it do that. Everyone put your hand on it. Let it be natural, and we'll see. Yeah, it's floa...
**Dee Kitchen:** It was a fix... \[laughs\]
**Mat Ryer:** ...what's your unpopular opinion? It was a fix, yeah.
**Dee Kitchen:** Mine comes from the last Go Time. One of the guests said that Go is brilliant, you don't have to worry about security; it does everything for you. You don't have to worry about the memory management. Everything's super cool. And I think it actually has made Go more insecure, because people are so -- th...
For me, the number one thing people should do is sanitize inputs. And it's not because I wrote bluemonday but they should do it on everything. And I just don't think I see anyone doing it anywhere. There's just great, big holes in everything, but people are still there going "But we've got memory safety." Memory safety...
**Mat Ryer:** Hm... What do we think? Is that popular, or unpopular...?
**Kris Brandow:** Well, it should be popular... Sanitize all your inputs?
**Dee Kitchen:** It should be. But if you look at all of the open source stuff that's out there, very few people actually sanitize, check, validate their inputs. They're just like "I've mapped this input directly to a struct, and I'm going to use it." They take their form fill, and they're on their way.
**Mat Ryer:** Yeah. One simple version of that is just a limit reader when you're reading a body, or like of a request; you can error if it's too big, and things like that. There's bits like that. But you end up doing quite a lot of that heavylifting yourself every time.
**Dee Kitchen:** There are libraries out there where you can add tags and say "This should be a text field. It should be no longer than this length. There should be a number, and it should be no longer than this." But far too few projects do it.
**Mat Ryer:** Do they use reflection? I think I've avoided them if they -- but it's not a great reason to avoid it. I just tend to not...
**Dee Kitchen:** Why are you afraid of your reflection? Are you a vampire?
**Mat Ryer:** Well, it's because I am DraCool -- Yeah because you know, that's my... Russian accent there.
**Kris Brandow:** Because he doesn't want to see that hairline, obviously...
**Johnny Boursiquot:** Ohh...!
**Mat Ryer:** That's why I don't have mirrors...
**Johnny Boursiquot:** Kris is in on it... Alright, everybody take a turn.
**Mat Ryer:** Yeah, Kris is in on it.
**Johnny Boursiquot:** Take a stab at Matt... \[laughs\]
**Mat Ryer:** \[54:10\] I'm like a pinata. I'm like a really rubbish pinata. Imagine buying a pinata for kids and it's me. \[laughter\] You'd take it back, wouldn't you? You'd be like "No, we'll probably go for the unicon instead, on second thought... I should have guessed that, really..." Okay, yeah. Fine. Thanks, Kri...
**Natalie Pistunovich:** Spooky pinata.
**Mat Ryer:** Yeah, exactly. Okay, and other unpopular opinions?
**Natalie Pistunovich:** I have one.
**Mat Ryer:** Natalie PistunoWitch...! \[wolf howl\] They don't know I've just done that, so it just sounded like a sound effect in the background. Come on.
**Natalie Pistunovich:** Some of the training that you should be taking occasionally throughout your career, even annually, should not be about things that are in the future, like new things, like new technologies coming and so on, but also a little bit about the back. A little bit of Assembly every now and then. It mi...
And it's unpopular -- I know, you all will not agree with me, it's unpopular. I also did not do that, and don't allocate time or budget for that.
**Mat Ryer:** Hmm... I do know what you mean. I actually have this book called, "But how do we know?" I got it off the Amazon website. And basically, it talks about computing from the very bare beginnings, like literally logic gates, and then how you make a bit out of two NAND gates, just showing how the logic works......
And actually, something else that occurred to me when you were saying that one is having like training or paying attention to things that you already think you're good at. So not just new things that are new to you. Things that you already think, "Yeah, I've got that nailed." You might be surprised; like, plenty of oth...
**Natalie Pistunovich:** Even the way you did that is interesting, because you were already a couple of years a software developer, and then you look into gates, and so on, and that kind of helped you put this in place. When I started my degree, the first course I did was those logic gates, and everything was scary; ca...
**Dee Kitchen:** I think that's the path that people take accidentally. Like, those who do bootcamps, and then they gradually, eventually, over like 5-10 years become like systems engineers and are working on like the Kernel, or TLS, or something - they don't know they're doing that, but that's kind of what we're doing...
**Natalie Pistunovich:** We should open a university teaches that way.
**Kris Brandow:** I feel like that's how my career has been. I just have gotten like down the stack further and further...
**Mat Ryer:** That's interesting, yeah.
**Kris Brandow:** It's been fun. I've written like a few operating system kernels, like toy kernels. It was infuriating. Modern processors are terrible... But mostly because they're so old. Like, "Oh, maybe I have this code from the '70s I might need to run on my Intel 12-gen chip", or something. You never know. It's l...
