[THEME MUSIC]


ALEX GOLDMAN: Fom Gimlet, this is Reply All, I’m Alex Goldman.


PJ VOGT: And I’m PJ Vogt.


ALEX:  And this week PJ, we’ve have a Super Tech Support.


[MUSIC] 


PJ: Super Tech Support is a segment on our show where listeners come to us with their weird, unsolvable tech problems, and one of us, usually you, goes out  and tries to solve it for them.


ALEX: Ummhmm.


PJ: And you have one.


ALEX : I do.


PJ: Tell me about it.


ALEX: So we got an email from a guy named Ben. He lives in Houston, and Ben is a huge fan of podcasts. He has his own podcast. He said he listens to over 100 podcasts, which, like, I don’t even know how that’s possible. He said that the one complaint he has about his podcast app is that it tallies how much time he spends listening to podcasts.


BEN: It tells me how many overall days of podcasts I’ve listened to, and it’s just more and more depressing. 


ALEX: You know — 


BEN: Would you like to guess?


ALEX: Sure. Yes. Uh…


BEN: Alright.


ALEX: Forty days.


BEN: One hundred and thirty three.


ALEX: Oh my God.


ALEX: And recently he started having this very strange podcast-related problem. 


PJ: Which is what?



ALEX: So, Ben not too long ago got a new car, it was a 2016 Mazda 6. And the thing that he was most excited about was that he could pair his phone using Bluetooth, so he can listen to podcasts.


PJ: Oh, before he was an aux-in guy?


ALEX: Yes. Anyway, for some reason, the radio in his new car refuses to play one podcast and one podcast only.


PJ: Which is?


ALEX: Uh, the Radiotopia podcast, 99% Invisible.


PJ: Really?


ALEX: Yes. And it’s driving him absolutely insane.


PJ: His car bluetooth has rejected Roman Mars and his stories? 


Alex: Yes.


PJ: Um, like, obviously for people who don’t know, 99% Invisible, hosted by Roman Mars. It’s like this really great non-fiction podcast. They tell all these stories about design, like how things work in the world and why they’re made the way they’re made, like the stories behind those things. Um, and- and apparently it’s the one podcast that doesn’t work on his car?


ALEX: That’s right. So I asked Ben to play 99% Invisible through his car stereo while he was on the phone with me. 


ALEX: Can you tell me exactly where you’re sitting at the moment? 


BEN: Alright, I’m sitting in the driver’s seat in my 2016 Mazda 6.


ALEX: Okay. Um, and...Let me know when you press play?


BEN: Alright, so, I’m going to press play right now.


ROMAN MARS: This is 99% Invisible, I’m Roman Mars...


ALEX: The show does start playing, but like the display screen on the radio freezes immediately, the buttons on the car stereo stop working, he doesn’t have any control—it’s just playing on it’s own.


ROMAN: ...in particular dominated the room. The tour guide...


ALEX: And then after about a minute...


BEN: Hold on, the screen just went black. And now it’s cut off and restarted…And I’m not playing 99% Invisible anymore because every time I’ve done that if it’s still playing, it will freeze again. 


[MUSIC] 


PJ: How could you have a tech problem where the trigger was like content?


ALEX: I know it’s weird, right?


PJ: It’s very weird. It's like, it would make more sense to me if like, it broke down anytime he tried to listen to like podcasts that weren't–if it didn't work for Car Talk, it'd be like, okay, maybe his car doesn't want to hear stories about sick cars, maybe that's like upsetting or something like that or–


ALEX: I really like that you've immediately (PJ laughs) gone to like the car has achieved sentience.


ALEX: Do you have any theories about what’s going on?


BEN: I don’t know. My, my best guess is thatbecause I looked at the file sizes, And I listen to things like Hardcore History and, and Blank Check which have big file sizes. Um, and it’s not that. My best guess is maybe he’s using some sort of weird audio codec that interacts strangely with my system, but I really couldn’t tell you. So I don’t know. 


ALEX: he thinks that because Roman’s voice is so whispery and close in the podcasts—maybe he’s doing some specific and technical to the files to achieve that?


PJ: That would be my actual guess is like it’s like..something about actual kind of file, like the way Roman is putting-is converting his podcast to an mp3, that’s just too complicated for Ben’s car system.  


ALEX: And I was thinking about it, and I was like, these are two constants in his problem: one is the podcast. It’s always the same podcast. And the other is that it’s always the same radio. I was like maybe he just has like a bad radio.


PJ: But even if it’s a bad radio, it’s still interesting because like why is this radio bad only with 99% Invisible?


ALEX: Not only that.


PJ: But?


ALEX: We got another email. From another person experiencing exactly the same problem. With exactly the same podcast.


PJ: That is so weird.


[MUSIC] 


ALEX: Um, alright, so I have to figure this out. 


PJ: Okay, cool. 


[phone ringing]


ROMAN MARS: Hello?


ALEX: How’re you doing?


 ROMAN: I’m good. How’re you doing?


ALEX: I’m good. Um, (ROMAN: Good.) it is a pleasure to hear your voice, not on a podcast.


 ROMAN: Yes. Yeah, I’m- I’m–me as well. I was very delighted to get your email. 


 ALEX: Uh, are you- are–are you totally in the dark as to why I would reach out to you?


 ROMAN: Totally. 


ALEX: So, I told Roman why I was calling him, and I told him about what was going on with Ben’s car.


ALEX: There is one that causes his car stereo to freeze, shut down, and restart. 


ALEX: And Roman had actually heard about this problem from other listeners.


ROMAN: Yeah, I don’t know what it is, and we got some details for it a few times from a few different people, but um, I’ve never really figured it out.


ALEX: All Roman knows is that in some cars, Bluetooth plus car radio plus 99% Invisible causes everything to break. But he has no idea why, so I ran Ben’s theory by him.


ALEX: And he was like, “Well, Roman obviously cares about the, uh sort of, texture of the sound. Maybe he's doing something very specific to his files." And I'm curious like–


ROMAN: No (laughs) no.


ALEX: Like, what is your (ROMAN: No.) setup like? Do you have a strange microphone of some kind?


ROMAN: No. I mean we have, um, a couple. I use like a shotgun mic in the studio.


ALEX: But you’re not using some kind of special encoding settings that are different from the rest of Radiotopia?


ROMAN: No. No. 


ALEX: But Roman said he had a theory that’s he’s actually pretty confident about, which is that the thing that makes our podcast different unusual is that we use the percent sign. 


PJ: The percent sign, as in the percent sign in 99% Invisible?


ALEX: Yeah. 


PJ: Oh.


ALEX: He was like, "It must just not play well with the stereo for some reason."


PJ: So it's like, because the stereo can also display the name of the podcast there's something about just there being a symbol, where it doesn't expect there to be a symbol, where it breaks. 


ALEX: Yeah. And it really bums Roman out honestly. He’s been hearing about the problem for years from other people who are not Ben, but like, what can he do about it? He not gonna change the name of the podcast.


ROMAN: You know, like, I would love it to be fixed and I really, if someone is a fan of the show, I really hate for them not to be able to hear it. Like, I wish it could be better, but I think I recognize the futility of me fighting it, I think is the thing. 


ALEX: I feel like a primary fundamental tenet of Super Tech Support is realizing (ROMAN: Mhm.) that something is futile (ROMAN laughs) and well over–well outside of our capability, and putting on a football helmet and (ROMAN laughs) running headfirst into it anyway. 


ROMAN: Well I mean if you solve it, I would be really grateful. It’s just that- it’s just like when itit just seemed there’s- these–this is one of those things where all of these technologies are butting up against each other. 


[MUSIC] 


And all I am is some little bit of grit that gets caught between the gears of, you know, tech companies, you know, not knowing how to pass things off and talk to each other. That’s what I feel like I am. 



The irony of this was of this was crazy-making. Like 99% Invisible, a podcast dedicated to explaining the beauty of good design– that is the one podcast that breaks when you try to play it on Ben’s Mazda? It just felt like an imbalance in the universe that I had to correct. 


And Roman’s theory about the percent sign, it felt really plausible to me. So, I figured I’d start there, if the percent sign is giving the car trouble because it’s a special character, other special characters should break the car, too. I wanted to test that theory.  


PJ: Because basically you’re thinking like classic tech support problem, like you have to replicate the glitch to understand it, to solve it.


Alex: Exactly. So I started thinking about other special characters, like you know what about the carrot or the curly brackets or whatever.


PJ: The curly brackets?


ALEX: You know, the curly brackets–


PJ: Oh, yeah, yeah, yeah–


ALEX: That are right next to the p?


PJ: Yeah, they look like they'd be music notation?


ALEX: Mhm.


PJ: Okay.


ALEX: So, we wanted to make a podcast that would break his stereo. And to do that, we devised a test. 


PJ: Uh huh. Who's we?


ALEX: Me, uh, most of the team, to be honest.


PJ: Okay.


ALEX: It was me, Tim, Anna, Phia, Emmanuel, Sruthi, Damiano.


PJ: I was about to make fun of you guys, because I was like, “Oh, why does it take that many people to make a podcast?” But it’s like literally (laughing) it takes that many people to make this podcast, so why wouldn’t it? 


ALEX: Also...we didn’t make one podcast. 


PJ: How many podcasts did you make?


ALEX: Well, let’s just start at the beginning. 


PJ: Okay. 


ALEX: So the first, first podcast we made is called, uh, “Carrot Space Carrot.” You know the carrot which is above the six–


PJ: The carrot, the up, the little pointy, the pointy upwards arrow?


ALEX: Yeah.


PJ: Okay, it's called “Carrot Space Carrot.”


ALEX: Mhm.


PJ: Whose job was it to make the podcast art? 


ALEX: Oh, it was mine. 


PJ: Okay. Oh that’s pretty nice. It’s like a child’s drawing of like a Bug’s Bunny carrot, and then in the background, there’s a planet. Oh I get it, it’s like, carrots and space.


ALEX: I'm just going to play it for you. 


PJ: OK.


[music plays]


PJ: Oh god, we are in Alex Goldman territory.


ALEX: (laughs)


PJ: That synth. 


ALEX: Hello, Carrot Space Carrot podcast...podcast...podcast.


ALEX: I recorded this in my attic


PJ: (laughs) I feel like this is the ASMR that like printers listen to when they're trying to when they’re trying go to sleep at night.


[music continues]


ALEX: The atomic red carrot has slim roots that travel forward through time.


PJ: You're describing what?


ALEX: The atomic red carrot.


PJ: I hate this.


ALEX: Time produces daucus carota or Queen Anne's lace.


ALEX: Don't you just feel like relaxed?


[music continues]


PJ: No, I don't feel relaxed.


ALEX: How do you feel?


PJ: I feel like a robot's trying to mug me. Like, a robot's trying to hypnotize me to go to sleep so it can mug my data.


ALEX: Queen Anne's lace annihilates negative Queen Anne's lace.


PJ: I think I've had enough of this podcast.


ALEX: Okay. So, we made this podcast. We uploaded it to podcast apps, and to an RSS feed.


PJ: Uh huh.


ALEX: We gave it to Ben.


PJ: Uh huh.


ALEX:  And I asked him to try it in his car.


ALEX: Go ahead and listen... And we’ll see if it breaks your-uh, car stereo. 


BEN: Alrighty let’s do it. And play. 


[music starts] 


 ALEX: Hello. Welcome to the “Carrot Space Carrot” podcast.


BEN: (laughs)


ALEX: Can you look at your screen and see how this is affecting your stereo?


BEN: So I have to tell you, it’s, uh, it is functioning completely normally. 


PJ: Interesting. It also means it’s not filtering for the quality of podcasts. 


ALEX: (laughs) So, then we wanted to make a podcast to test the less than symbol, the tilde, which is like the symbol that means approximately, and the greater than symbol. 


PJ: Okay. 


ALEX: And I’m just going to play you the beginning.


PJ: Okay. 


[music]


PJ: Oh, that’s jaunty.


[music]


SAMIN NOSRAT: Hi! This is Samin Nosrat. Welcome to Greater Than–


PJ: You got Samin Nosrat to make your fake podcast!


ALEX: Yes.


PJ: Jesus. 


ALEX: Samin wrote the book Salt Fat Acid Heat and uh she has a Netflix show by the same name. 


PJ: Such a waste of talent (laughs).


[music]


SAMIN: Today, I’m joined by a cooking newbie, Alex Goldman.


ALEX: Hey! Thanks for having me!


SAMIN: Oh, I’m so glad you could be here!


PJ: You got her to teach you cooking! I’ve been trying to learn cooking from her book for like a year.


SAMIN: A berry clafoutis --


PJ: Aw, I hate you.


SAMIN: is basically a pancake with berries in it. But instead of being cooked on the stove, it’s cooked in the oven.


ALEX: OK.


SAMIN: Do you feel like you can do that with me today?


PJ: She taught you this?


ALEX: Well.


PJ: For a Mazda?


ALEX: What you have to understand about this is this isn’t your average cooking show.  Because the only way that she could give me instructions is by telling me the ingredients were less than, approximately, or greater than a eighth (laughs).


PJ: I ha–my heart is so–it’s just such waste. 


ALEX: Uh, less than, approximately, or greater than some other thing. So let me find an example here. 


SAMIN: The measurement for the sugar should be about, do you, have you ever had one of those toys that you, you know, those stress-balls?


ALEX: Uh, yes.


SAMIN: Okay. You should put about a stress-ball amount of sugar into the bowl. 


ALEX: So you’re saying like, greater than one of those super balls. 


PJ: This is...


SAMIN: Yes, great–greater than a super ball, but less than a softball. 


PJ: This is so stupid (laughs).


ALEX: Okay. 


SAMIN: Okay. For the eggs, can you add an amount of eggs that’s greater than the number of nipples you have?


(PJ laughs)


ALEX: So, you’re saying like, less than the sides of a square?


SAMIN: Correct. 


ALEX: (laughs) Anyway, the berry clafoutis I made, as you might imagine–


PJ: Didn’t turn out good?


ALEX: Was not edible. 


PJ: Yeah. So did this break the Mazda?


ALEX: He popped it in his podcast player. 


BEN: Alrighty.


SAMIN: Hi, this is Samin Nosrat. Welcome to Greater Than, Less Than, Approximately.


BEN: It seems to be working just fine.


ALEX: Okay.


ALEX: So at this point we have tried the carrot, the tilde, the less than sign, the greater than sign—we even made another podcast to test the the plus sign, the equals sign, the curly brackets and none of them are replicating the problem. 


PJ: Have you ever had the thing happen where you go to get like an object repaired, and the people in the repair shop care about the object differently than you care about it? (ALEX: Mhm.) Do you know what I mean? Like they’re like, “Oh what this guitar really needs is like to be like a double-neck guitar.” And you’re like, “No it doesn’t.” But then they’re just like, doing it and they’re off and doing it and you realize like they have more of a relationship to the work they want to do than to helping you?


ALEX: I don’t know what you’re talking about. 


PJ: Yeah me neither. Okay. 


ALEX: But, of course, at this point, we were definitely going to test the percent sign, right?


PJ: Right. 


ALEX: So–


PJ: Some would have argued you could have just started by testing the percent sign. 


ALEX: Some would.


PJ: Some would argue you seem to just want to make a bunch of garbage podcasts. 


ALEX: How dare you call these garbage. So, we made a podcast that was called, “100% Related?” 


 [music]


ALEX: Hi, my name’s Alex Goldman, and you’re listening to 100% Related?


ALEX: The premise of this is a couple days ago, I was talking to our editor Tim Howard, and he insisted that I was only 50% related to my dad because I only have 50% of my dad’s genes. 


PJ: And, so you’re 50% related to your dad and you’re 50% related to your mom?


ALEX: I’m a hundre–my opinion is I’m 100% related to both of my parents.


PJ: But in Tim’s worldview.


ALEX: Yes. And so what we did is we got my dad, who–a former judge, to adjudicate this argument.


TIM HOWARD: What should I call you? Should I call you Judge Goldman, or should I call you...?

 MARC GOLDMAN: No, you can call me Marc.

           TIM: Mark. OK.


PJ: Okay. He seems very biased in this, but whatever. 


ALEX: Now I'd like for you to lay out your case, Tim, because what you're saying is insane. 


TIM: (laughs) Well.


MARK: (laughs)


TIM: It really just seems to me that if you were 100% related you would, you would be Mark. 


ALEX: (laughs)


MARK: (laughs)


TIM: And you are not. You're 50% related.


ALEX: So, okay. What–


MARK: Go ahead Alex–


ALEX: All I'm saying is like, I'm 100% related to anyone who's my relative. 


TIM: So you are as related to your father as any other human being. That's what you're saying–


PJ: Me and Tim are on the same page.


ALEX: Spoiler alert. So was my dad.


PJ: Oh, Tim–your dad took Tim's side?


ALEX: Yes.


PJ: Good man. 


ALEX: So.


PJ: Why is this the podcast I like? Because I like arguing with you? It's like for fans of arguing with you?


ALEX: Yeah.


PJ: Oh, I don't feel good.


ALEX: (laughs) So, the percent sign. We–


PJ: Oh, right. There’s a point to this.


ALEX: There’s a point to this.


PJ: He listened to the thing. I feel like I’ve fallen into your vortex.


ALEX: (laughs) So, clearly we were wrong about all those special characters breaking the radio which surprised me, but I just wanted to confirm the one thing we were actually confident was true, which is the percent sign will break the radio. 


ALEX: So, I give Ben the podcast. 


 BEN: Alright let’s do it. 


 ALEX: Alright. [podcast starts] I have to know, is it freezing your stereo?


 BEN: Alex, I’m really sorry to say no. 


[MUSIC] 


(ALEX gasps) 


BEN: It is totally normal. 


 ALEX: But how is thathow is that possible? 


ALEX: So, clearly, this caught me off guard. 


PJ: So Roman’s whole theory that he found so obvious does not seem to be founded. 


ALEX: It doesn’t seem to be founded. And so at this point I started thinking that it has to be something within the file itself that they are uploading that is busted—that it doesn’t actually have anything to do with the percent sign.


PJ: Interesting. 


ALEX: But then Ben tells us something that again, befuddles us.


PJ: Okay.


ALEX: Which is, Ben found a copy of a 99% Invisible episode on YouTube and tried playing that over his car stereo.


PJ: Yeah. So he was like, “I’m gonna see if it works–if pirated 99 PI works?”


ALEX: Yeah. 


PJ: And?


ALEX: It breaks the car. 


PJ: It breaks the car?


ALEX: I mean it breaks the stereo–


PJ: It does the same thing. 


ALEX: Yeah. 


PJ: Which is weird, because it just means like, it’s not something anything about the file itself because when someone is uploading a podcast to Youtube, that’s like, that’s a totally new file.


ALEX: Yes. 


PJ: It’s like the content. 


ALEX: Right. 


PJ: It’s like the car is sentient and doesn’t like Roman Mars. 


ALEX: And so Ben was like, “The only option is that there must be some–some sonic frequency that is breaking the car.” And I was like–


PJ: There’s like a note in Roman’s voice that if he were just sitting in a Mazda and started talking too loud–


ALEX: The car would explode–


PJ: The car would just explode. That’s wild. Also when I was a kid, there was a rumor that there was one note that would make you poop your pants. 


ALEX: Oh yeah, the brown note. 


PJ: Yeah. 


ALEX: I’m very familiar. 


PJ: Is that–that’s not real.


ALEX: I don’t think it’s real. 


PJ: We both know that’s not real. 


ALEX: But–we both know it’s not real, but I’m glad you brought it up. 


PJ: Okay. 


ALEX: I’ve been thinking about it this whole time–


PJ: I could hear you thinking about it (laughs). 


ALEX: I’ve been thinking about it, I’ve been thinking about it since this story began. And I’ve been like, “I’m in mixed company. I can’t bring this up.” 


PJ: I can’t believe you stopped yourself from saying something one time (PJ & ALEX laugh). Do you think Roman was thinking about it? Do you think everybody was thinking about it the whole time?


ALEX: The Brown Note?


PJ: Yeah. 


ALEX: I hope so. 


PJ: Okay. 


ALEX: Uh, so, we’re–we’re like, okay, we have no idea. We’re like totally back to square one. 


PJ: You gotta find the brown note. 


ALEX: Oh boy. (PJ laughs) Oh boy. And the other reason this doesn’t make any sense is because Roman has another podcast. 


PJ: About Trump. And constitutional law.


ALEX: Yeah. it’s called “What Trump Can Teach Us About Con Law.”


PJ: And what happens with that one?


ALEX: It plays fine. Roman’s voice doesn’t break the radio when it’s that podcast. Only when it’s 99% Invisible.


PJ: Huh. So what happened? You called John Mazda? 


ALEX: We called the company that makes the radio. 


[MUSIC] 


We called Ben’s Mazda dealer. 


ALEX: And we are specifically dealing with a Mazda tech problem from a person who’s 

in your service area, and I was wondering if I could ask you a question or two about it.


CAR DEALER: Okay let me…


ALEX: They weren’t familiar with this issue. We called Andrew Kuklewicz, the CTO of PRX -- The public radio exchange.


ANDREW KUKLEWICZ: Hello this is Andrew.


 ALEX: Hi Andrew. This is Alex Goldman, how are you doing?


 ANDREW: Oh hey Alex. How are you?


 ALEX: I’m good…


ALEX: He's in charge of how the show gets uploaded to podcast apps and RSS feeds.


PJ: So you’re just calling everybody being like, “Have you heard of this?” 


ALEX: Yeah. And Andrew said that he’d heard of it, and that he’d always figured that like Roman, it was the percent sign, but I told him about the tests we’d done.


ALEX: And all of them worked including 100% Related. 


ANDREW: No. 


ALEX: Yeah.


ANDREW: Crap. That’sugh, these are like so painful, these kinds of bugs. 


ALEX: No one knew what was going on. And then–


PJ: I wanna solve this ahead of you. 


ALEX: Uh, so did Ben, he actually got back in touch with us and said I have been doing some testing on my own. I’ve been uploading a couple of podcasts, and what I found is that it’s not the percent sign alone that is causing this issue. It’s the percent sign followed by an uppercase “I” that shuts down the radio.


PJ: So, Lowercase “i”, it doesn’t?


ALEX: Uppercase “I”, it shuts down. That’s all we know. We don’t know why. 


PJ: Uppercase “I”, your car doesn’t fly. Lowercase “i”, podcast in the sky–


ALEX: You’re a great guy. (PJ laughs) That’s exactly right. So I mean, so we’re getting closer. And then, you know our pal Kurt Melby who–


PJ: Works at Gimlet?


ALEX: Works at Gimlet


PJ: Who I play Fortnite with most weekends. 


ALEX: Who does coding at the–at the office?


PJ: Yeah. 


ALEX: He had an idea


[MUSIC] 


ALEX: Kurt?


 KURT MELBY: Alex. 


 ALEX: Thank you for coming into the studio today. 


 KURT: Thank you, glad to be here. 


 ALEX: Um, so the reason that we–I have you here is because you’re the person who 

actually uploaded the, uh, podcasts that we made. 


KURT: Yeah. That was fun.


ALEX: (laughing) And I don’t know if you know this, but none of them worked. 


KURT: I listened to them also, and they were, they were pretty entertaining. But yeah, no, I’m, I’m not surprised that that didn’t work. (laughs)


ALEX: Alright smart guy. 


ALEX: Kurt says, “I have a theory. And the theory is that in the programming language C”–


PJ: Uh-huh. Oh, I know what it is. I know what happened. Literally 99% means something. It means turn off your stereo (ALEX laughs) in the programming language C.


ALEX: You’re close, but not exactly. In the programming language C, um, basically in some scenarios the percent sign means, “Hey, the character immediately after  me ..the character immediately after the percent sign, think about me like code rather than, like text.”


PJ: Oh.


ALEX: And–and start parsing that as though it–it’s asking you to run commands. 


KURT: And there’s a thing called printf in C that’s like used very, very commonly and heavily. And other languages have copied this feature to interpolate, is the technical term, (laughs) interpolate the number into the string. 


ALEX: And he said percent “I” in um–


PJ: C.


ALEX: In C, is a command whereas percent r, which would be 100% Related, question mark, is not. So like–


PJ: What's the command? What does percent i tell a computer to do?


ALEX: So, I have it up here. It has to do with, basically the percent in, in C has to do with displaying integers in C. I know, this is very confusing. 


PJ: Oh my brain’s mathing. 


ALEX: Yeah, I know. So percent and then a bunch of different letters tell it to display integers in a certain, in a certain way. 


PJ: But basically what’s happening, it sounds like, is the car stereo, it gets what it thinks is a audio file, what is an audio file. And it’s like, “Okay this part of the information I have is just for the humans. This is like the title to display.” 


ALEX: Yeah 99, and then it–there’s the percent–


PJ: And then it’s like, “Okay now here is some stuff for you, the robots, to understand.”


ALEX: Mhm.


PJ: And it gets a bunch of gobbly gook and it gets confused and it shuts down. 


ALEX: Yes. 


PJ: Wow. 


ALEX: So there’s a bunch of different commands in C that would cause this to happen. 


PJ: Okay. 


ALEX: And so, we were like, “Ok, if Kurt’s right, we should be able to test this with other commands and those should also mess up the car stereo.”  And so, we made one more podcast.


PJ: Oh no. Okay. 


ALEX: With another one of the–another one of the recognized pieces of syntax which is, um, the letter–which is the letter “p,” which when it follows the, uh, percent sign becomes the pointer address, whatever that means. 


PJ: Okay. But whatever, as long as it’s going into code it should shut down the stereo–


ALEX: Mhm–


PJ: If that’s what’s happening. 


ALEX: So we made a podcast that's called 88% Parentheticals.


PJ: Uh huh. 


ALEX: Here you go.

PJ: Oh no.


SARAH: You're listening to 88% Parentheticals.


PJ: This is so wrong.


[music]


SARAH: I'm going to tell you about this document I'd been waiting for.


PJ: (laughing) No!


SARAH: This one piece of paper that was going to change everything I thought I understood up to now. It arrived on a Monday. Monday began like a normal day. I was walking to work with my dog, his name is Bruno by the way.


SARAH: He didn't come with that name. I named him Bruno. He's a rescue dog. He came with the name like Bradley or something, which I really didn't like, so I changed it to Bruno, which by the way is the name I also wanted to name my son. But my husband nixed that.


PJ: We're in a parenthetical. I understand. I understand what you've done.


SARAH: Anyway, I'm walking to work, with Bruno, and we get there. It's a short walk like maybe ten minutes, which is crazyBecause people are always like, "What podcasts do you listen to? What podcasts do you listen to?" SARAH: "Because you made podcasts." And I'm like, "Not that many because I have such a short walk to work." Anyway, so I like–


PJ: (whispers) This is just wrong. OK, I've heard enough.


ALEX: OK!


PJ: I don't want to live in a world where you can take up (ALEX laughs) Sarah Koenig's time with this. 


ALEX: (laughs)


PJ: Also there's like people that are like, "Oh, when's the next season of Serial coming out?" Like twenty minutes later than it would have.


ALEX: (laughs)


PJ: So what happened?


ALEX: Well, we sent it to Ben, and it didn't break the car stereo. 


PJ: So, what happened?


ALEX: It didn't break it. 


PJ: So that screws up the whole theory.


ALEX: Absolutely.


ALEX: I mean we didn’t just try percent p...we tried a whole bunch of different things that should have broken the car stereo in the same way that percent ”i” does, and none of them caused a problem.


PJ: So what then? Is Kurt’s theory is bunk?


ALEX: Kurt’s theory appears not to work. The only combination that did anything was percent followed by an uppercase “i”.


PJ: Okay. But we don’t know why. 


ALEX: No, we don’t, and it is driving me nuts.


[MUSIC] 


ALEX: After the break…we finally find an answer for Ben.


BREAK


ALEX: Welcome back to the show. OK, so here’s where we stand at this point. All we know is that % uppercase “I” is the one commandthat can possess a car stereo, and Roman Mars just had the terrible luck of embedding that command in the name of his podcast. We don’t know why, and we don’t know how to fix it. And this is the point in the story where Andrew Kuklewicz comes to the rescue.


PJ: Andrew Kuklewicz?


ALEX: Remember, he’s the CTO at Public Radio exchange–the company that distributes 99% Invisible.


PJ: Uh huh.


ALEX: He really dove–like he really invested himself in this. 


PJ: What does that mean that he really invested himself in it? 


ALEX: Well, you know, we were trying to figure out a way to diagnose this properly without actually having access to the code. 


PJ: And you’d done everything you could. You made a bunch of nonsense podcasts for no reason. You talked to somebody who worked at a Mazda dealership, and one guy at work. 


ALEX: We also called Mazda.


PJ: (laughs) Uh-huh.


ALEX: Um, Andrew was on–got onto like a Mazda-owners message board and found the actual code–


PJ: What?


ALEX:  For the Mazda Connect Infotainment System.


PJ: Really?


ALEX: And within the code, found the name of one of the original authors of the original code, which he then gave to us. 


PJ: The author of the code for the Mazda car stereo program?


ALEX: Yes.


PJ: Wow.


ALEX: His name is Brandon Goozman. And–


PJ: Is it embarrassing that I don’t know–that I didn’t already know that you can look in code and see the code’s author? Like I didn’t know that?


ALEX: There’s a way to write your authorship in your code and it’s been done forever. 


PJ: And is it always like that? Like a signature on a painting?


ALEX: Mhm. It’s a little–a lot of times it’s harder to find. You have to have access to the code to see the authorship. 


PJ: Yeah.


ALEX: And my favorite story about this is, early in the development of Atari games, Atari would not allow the author of the game to put their name on it. 


PJ: Because they were just being a company about it?


ALEX: Yeah. And so the author of the game “Adventure” created this incredibly arcane set of things that you had to do in the game so that you would find a secret room that just flashed his in the center of the screen. 


PJ: That’s brilliant and sad. Like it’s just sad that they had to go to that much work to just be like, “I made this.” Anyway, so you got in touch with Brandon. 


ALEX: Yes. He uh, works on exercise technology now.


BRANDON GOOZMAN: I work for a company called Shapelog. We develop, uh, connected strength products.


 ALEX: As a person who’s terrible at exercising, uh, I’m not your target audience.


BRANDON: Yeah, the irony is the entire office, most of us working on this are not either. We’re more like, stay up late and sit at our computer longer people.


ALEX: So, we told Brandon what was going on with Ben's car and he told us that he was pretty sure he knew what was going on.


PJ: Which is?


ALEX: So, what he said was:


BRANDON: One thing that caught my eye immediately is that there’s a percent 

symbol in the name.


ALEX: Mhm. 


BRANDON: And that has some special meanings in things like a URL. 


ALEX: Right. 


BRANDON: In a URL, certain characters are allowed and certain characters are not. 


ALEX: So, our operating theory was that percent “I” was breaking the radio because the percent sign followed by the letter I meant something in the programming language C. But what Brandon told us was, no, that program wasn’t even written in C. It was written in a totally differ

ent programming language.


PJ: OK. 


ALEX: And to the radio, the %I doesn’t actually mean anything. And what Brandon thinks the problem is, is that the code should tell the radio to ignore things that it doesn’t understand or don’t mean anything, but in this case, for whatever reason, it’s not. So, the radio sees the %I and keeps trying desperately trying to figure out what it means.


PJ: So it’s like it’s having a panic attack. 


ALEX: Kind of. 


PJ: It’s like, “I–percent–percent I? Percent I? I don’t–percent I?” 


ALEX: And so then I said, “Okay so why is the stereo restarting?” And Brandon told me that when they designed the car, they made it so that the radio was regularly sending a little message to the rest of the car saying ”I’m working, I’m working, I’m working.” Brandon called it a heartbeat.


PJ: Uh-huh.


BRANDON: And the hardware layer is listening for that. And as long as it gets it, it’s 

happy. If it doesn’t get it, it will assume that the UI has frozen, and it will restart it to a known good state.


ALEX: It’s, it’s saying,“It’s not communicating with me.”


BRANDON: Yeah– 


ALEX: “Something is wrong.” And, and it just start–starts over. 


ALEX: So if it freezes up... 


PJ: Then, it doesn’t send the heartbeat. 


ALEX: It–it is trained to automatically shutdown and start back up–


PJ: Got it. Got it.


ALEX: So that is why the computer is–that’s why the stereo is restarting–


PJ: So it has a panic attack, and then it takes a nap, and then it wakes up and tries again. 


ALEX: I really like how much effort we’ve put into personifying these cars. 


PJ: I just understand that they’re sentient. I feel like this doesn’t actually go against my original theory. Like everybody else, they freak out when they don’t have the right answer. 


ALEX: Right. There is one other thing that was suggested to us several times along the way. Ben’s car stereo firmware is a few generations out of date (PJ laughs). So the theory is that if–


PJ: If he just updated the firmware.


ALEX: If you updated the firmware, it might fix this problem. Um, according to Mazda, it will. 


PJ: Huh.


ALEX: But, Ben looked into getting his firmware updated, and it was just too expensive for him. 


ALEX: However, that doesn’t mean we don’t have a more permanent solution for Ben and Roman. Because, Andrew Kuklewicz from PRX had a very sweet idea. 


ANDREW:  Maybe we’ve got to publish a version of 99% Invisible with some slightly different titles or something. I’d be willing to create the- the Mazda version of the feed.


ALEX: That would be great! That’d be super cool.


PJ: There’s just like a 99% Invisible for Ben and other Mazda owners’ feed?


ALEX: Well, I can say that people in Nissans have also reported having this problem, but yes, for Mazda owners and Nissan owners who are having problems with this specific infotainment system.


PJ: That’s a very niche podcast.


[MUSIC] 


ALEX: So I called Ben up one more time. 


ALEX: Just let me know if uh, if uh, when you’ve got it set up and ready to roll.


BEN: Will do. 


ROMAN: This is 99% Invisible. I’m Roman Mars. Tim Hartford is a master at picking out the perfect little story…


 ALEX: And everything’s working fine?


 BEN: Yep. So, this totally works. It’s playing normally, not freezing at all. It’s perfect.



ALEX: So, if listeners the same problem as Ben where it loses its mind every time you try to play 99% Invisible there is a solution, they can go to 99% Invisible’s website 99percentinvisible.org or 99percentinvisible.org uh go to the contact section, and send them an email. They will send you a feed that will work in your car. And all those other podcasts that we made to test Ben’s problem—they will be available wherever you listen to podcasts, and we will put links to them in our show notes. So people should definitely check them out. 


PJ: Or don’t.


ALEX: (laughs) Why would you say that?



PJ: It just is a waste of— 


ALEX: Sarah Koenig put in so much work. Samin!


PJ: You’ve wasted a lot of good people’s time, and now you’re trying to waste additional good people’s time by listening to them.


ALEX: No, I think that — 


PJ: I think that that is the case.


ALEX: Uh — 


PJ: We can take it on your judge podcast and figure it out.


ALEX: Do you want to do another one?


PJ: No. I don’t. I really don’t.


ALEX: Cause we could call my dad right now. He’s retired.


PJ: I know.
