• 1:11Lex Fridman?

  Having co-created and managed for a few years the world's largest community of programmers in Stack Overflow 10 years ago, what do you think motivates most programmers? Is it fame, fortune, glory, process of programming itself, or is it the sense of belonging to a community?

• 1:31Speaker 01

  I think it's puzzles, really. I think it's this idea of working on puzzles independently of other people and just solving a problem, sort of like on your own, almost. Although, you know, nobody really works alone in programming anymore. But I will say, there's an aspect of sort of hiding yourself away and just sort of beating on a problem until you solve it, like root force, basically, to me, is what a lot of programming is. It's like, the computer's so fast, right? You can do things that would take forever for a human, but you can just do them like so many times and so often that you get the answer, right?

• 2:07Lex Fridman?

  You're saying just the pure act of tinkering with the code?

• 2:10Speaker 01

  Yes.

• 2:10Lex Fridman?

  Is, is the thing that drives most probably the, the joy, the struggle balanced within the joy of overcoming? The, the brute force process of pain and suffering that eventually leads to something that actually works?

• 2:24Speaker 01

  Well, data is fun too. Like there's this thing called the, uh, the shuffling problem, like the naive shuffle that most programmers write has a huge flaw. And there's a lot of articles online about this because it can be really bad if you're like a casino and you have an unsophisticated programmer writing your shuffle algorithm. There's surprising ways to get this wrong, but the neat thing is the way to figure that out is just to run your shuffle a bunch of times and see like how many orientations of cards you get. You should get an equal distribution of all the cards. And with the naive method of shuffling, if you just look at the data, if you just brute force and say, okay, I don't know what's going to happen. You just write, write a program that does it a billion times and then see what the buckets look like of the data. And the money hall problem is another example of that where you have three doors and somebody gives you information about another door.

• 3:08Speaker 01

  So the correct answer is you should always switch in the money hall problem, which is not intuitive and people, it freaks people out all the time, right? But you can solve it with data. If you write a program that does the money hall, you know, game and then never switches, then always switches, just compare, you would immediately see that you don't have to be smart, right? You don't have to figure out the answer algorithmically. You can just brute force it out with data and say, well, I know the answer is this because I ran the program a billion times and these are the data buckets that I got from it, right?

• 3:34Lex Fridman?

  So empirically find it, but what's the joy of that? What, what, so for you, for you personally, uh, outside of family, what motivates you in this process?

• 3:44Speaker 01

  Well, to be honest, like I don't really write a lot of code anymore. Like what I do at Discourse is like managerial stuff, which I always kind of despised, right? Like as a programmer, you think of managers as people who don't really do anything themselves. But the weird thing about code is like, you realize that like language is code, like the ability to direct other people lets you get more stuff than you done than you could by yourself anyway.

• 4:07Lex Fridman?

  You said language is code?

• 4:09Speaker 01

  Language is.

• 4:09Lex Fridman?

  Meaning communication with other humans?

• 4:11Speaker 01

  Yes, it is.

• 4:12Lex Fridman?

  You can think of it as a systematic. So what, what is it like to be? What makes, before we get into programming, what makes a good manager? What makes a good leader?

• 4:21Speaker 01

  Well, I think a leader, it's all about leading by example, first of all, like, sort of doing and being the things that you want to be. Now, this can be kind of exhausting, particularly when you have kids, because you realize that your kids are watching you like all the time, like even in ways that you've stopped seeing yourself. Like, the hardest person to see on the planet is really yourself, right? It's a lot easier to see other people and make judgments about them, but yourself, like, you're super biased. You don't actually see yourself the way other people see you. Often, you're very, very hard on yourself, in a way that other people really aren't going to be. So, you know, that's one of the insights is, you know, you've got to be really diligent about thinking like, "Am I behaving in a way that represents how I want other people to behave?" Right? Like, leading through example. There's a lot of examples of leaders that really mess this up, right?

• 5:04Speaker 01

  Like, they make decisions that are like, "Wow, that's... Why would... You know, it's a bad example for other people." So, I think leading by example is one. The other one, I believe, is working really hard. And I don't mean like, working exhaustively, but like, showing a real passion for the problem. Like, you know, not necessarily your solution to the problem, but the problem itself is just one that you really believe in. Like, with Discourse, for example, the problem that we're looking at, which is my current project, is how do you get people in groups to communicate in a way that doesn't like, break down into the howling of wolves, right? Like, how do you deal with trolling? Not like, technical problems of, "How do I get people to post paragraphs? How do I get people to use bold? How do I get people to use complete sentences?" Although, those are problems as well. But like, "How do I get people to get along with each other?" Right?

• 5:48Speaker 01

  Like, and then solve whatever problem it is that they set up to solve, or, you know, reach some consensus on discussion, or just like, not hurt each other, even, right? Like, maybe it's a discussion that doesn't really matter, but are people like yelling at each other? Right? And why? Right? Like, that's not the purpose of this kind of communication. So, I would say, you know, leadership is about, you know, setting an example, you know, doing the things that represent what you want to be, and making sure that you're actually doing those things. And there's a trick to that, too, because the things you don't do also say a lot about what you are.

• 6:17Lex Fridman?

  Yeah, so let's pause on that one. So those two things are fascinating. So how do you have as a leader that self-awareness? So you just said it's really hard to be self-aware. So for you personally, or maybe for other leaders you've seen or look up to, how do you know the both of the things you're doing are the wrong things to be doing? The way you speak to others, the way you behave, and the things you're not doing? How do you, how do you get that signal?

• 6:40Speaker 01

  There's two aspects to that. One is like processing feedback that you're getting. So.

• 6:44Lex Fridman?

  How do you get feedback?

• 6:45Speaker 01

  Well, right. So are you, are you getting feedback, right? Like, so one way we do it, for example, at Discourse, we have three co-founders, and we periodically talk about decisions before we make them. So it's not like one person can make a mistake, or like, wow, that's, you know, there can be misunderstandings, things like that. So it's part of like group consensus of leadership is like, it's good to have, I think, systems where there's one leader, and that leader has the rule of absolute law are just really dangerous in my experience. For communities, for example, like if you have a community that's run by one person, that one person makes all the decisions, that person's gonna have a bad day. Something could happen to that person, you know, something, you know, there's a lot of variables. So like, at first, when you think about leadership, have, have multiple people doing leadership and have them talk amongst each other. So they're giving each other feedback about the decisions that they're making.

• 7:27Speaker 01

  And then when you do get feedback, I think there's that little voice in your head, right? Like, or your gut, or wherever you want to put it in your body. Uh, I think that voice is really important. Like, I think most people who have any kind of moral compass are like, want to do, most people want to do the right thing. I do believe that. I mean, there might be a handful of sociopaths out there that don't, but most people, they want other people to think of them as a good person. And why wouldn't you, right? Like, do you want people to despise you? I mean, that's just weird, right? So you have that little voice that's sort of the angel and devil on your shoulder, sort of talking to you about like what you're doing, how you're doing. How does it make you feel to make these decisions, right? And I think having some attunement to that voice is important.

• 8:05Lex Fridman?

  But you said that voice also for, I think it's a programmer. Situation too where sometimes the devil on the shoulder is a little, a little too loud. So you're a little too self critical for a lot of developers, especially when you have introverted personality. How do you struggle with the self criticism or the criticism others? So one of the things of leadership is to do something that's potentially unpopular or what people doubt you and you still go through with the decision. So what's that balance like?

• 8:36Speaker 01

  I think you have to walk people through your decision making, right? Like you have to, this is where blogging is really important and communication is so important. Again, code language is just another kind of code is like, here is the program by which I arrived at the conclusion that I'm going to reach, right? It's one thing to say like, this is a decision, it's final, deal with it, right? That's not usually satisfying to people. But if you say, look, you know, we've been thinking of this problem for a while. Here's some stuff that's happened. Here's what we think is right. Here's our goals. Here's what we want to achieve. And we've looked at these options and we think this of the available options is the best option. People will be like, oh, okay. All right, maybe I don't totally agree with you, but I can kind of see where you're coming from. And like, I see it's not just arbitrary decision delivered from a cloud of flames in the sky, right? It's like a human trying to reach some kind of consensus about, you know, goals and their goals might be different than yours.

• 9:21Speaker 01

  That's completely legit, right? But if you're making that clear, it's like, oh, well, the reason we don't agree is because we have totally different goals, right? Like, how could we agree? It's not that you're a bad person, it's that we have radically different goals in mine when we started looking at this problem.

• 9:33Lex Fridman?

  And the other one you said is passion, so, or hard work, sorry.

• 9:37Speaker 01

  Well, those are tied together to, in my mind, let's say hard work and passion. Like for me, like, I just really love the problem discourse it's setting out to solve because in a way, it's like, there's a, there's a vision of the world where it all devolves into Facebook basically owning everything and every aspect of human communication, right? And this has always been kind of a scary world for me. First, because I don't, I think Facebook is really good at execution. I got to compliment them. They're very competent in terms of what they're doing, but Facebook has not much of a moral compass in terms of, Facebook cares about Facebook, really. They don't really care about you and your problems. What they care about is how big they can make Facebook, right?

• 10:11Lex Fridman?

  Is that you're talking about the company or just the mechanism of how Facebook works?

• 10:15Speaker 01

  Kind of both really, right? Like, and the idea with discourse, the reason I'm so passionate about it is because I believe every community should have the right to own themselves, right? Like they should have their own software that they can run. That belongs to them, that's their space where they can set the rules and if they don't like it, they can move to different hosting or, you know, whatever they need, they need to happen can happen. But like this, this idea of a company town where all human communication is implicitly owned by WhatsApp, Instagram and Facebook. And it's really disturbing too, because Facebook is really smart. Like I said, they're great at execution. Buying in WhatsApp and buying Instagram were incredibly smart decisions. And they also do this thing, I don't know if you know, but they, they have this VPN software that they give away for free on smartphones and it indirectly feeds all the, the data about the traffic back to Facebook. So they can see what's actually getting popular through the VPNs,

• 11:00Speaker 01

  right? They have low level access to the network data because users have let them have that. So.

• 11:06Lex Fridman?

  So let's, let's take a small pause here. First of all, discourse. Can you talk about, can you lay out the land of all the different ways you can have communities? So there's Stack Overflow that you've built, there's discourse. So Stack Overflow is kind of like a Wiki, Wikipedia you talk about, and it's a very specific scalpel, very focused. So what is the purpose of discourse? And maybe contrast that with Facebook. First of all, say, what is discourse?

• 11:33Speaker 01

  Yeah.

• 11:33Lex Fridman?

  Start from the beginning.

• 11:34Speaker 01

  Well, let me start from the very beginning. So Stack Overflow is very structured Wiki-style Q and A for programmers, right? And that was the problem we first worked on. And when we started, we thought it was discussions because we looked at like programming forums and other things, but we quickly realized we were doing Q and A, which is a very narrow subset of, of human communication, right?

• 11:52Lex Fridman?

  So, so when you started Stack Overflow, you thought, you didn't even know the Q and A.

• 11:57Speaker 01

  Not really. I mean, well, we didn't know. We didn't, we had an idea of like, okay, these are things that we see working online. We had a goal, right? Our goal was, uh, there was this site, Experts Exchange with a very unfortunate name.

• 12:08Lex Fridman?

  Thank you for killing that site.

• 12:09Speaker 01

  Yeah, I know, right? Like, and a lot of people don't remember it anymore, which is great. Like, that's the measure of success. When people don't remember the thing that you were trying to replace, then you've totally won. So it was a place to get answers to programming questions, but it wasn't clear if it was like focused Q and A, if it was a discussion. There were plenty of programming forums, so we weren't really sure. We were like, okay, we'll take aspects of Dig and Reddit, like voting were very important, uh, reordering answers based on votes, Wiki-style stuff of like being able to edit. Not just your post, but other people's posts to make them better and keep them more up to date. Ownership of blogging of like, okay, this is me. I'm saying this in my voice, you know? This is the stuff that I know and you know, you get your reputation accrues to you. And it's peer recognition. So you asked earlier, like what motivates programmers? I think peer recognition motivates them a lot.

• 12:55Speaker 01

  That was one of the key insights of Stack Overflow was like recognition from your peers is why things get done. Not necessarily money, necessarily your boss, but like your peers saying, wow, this person really knows their stuff. Has a lot of value. So the reputation system came from that. So we were sort of Frankenstein-ing a bunch of stuff together in Stack Overflow, like stuff we had seen working and we knew worked. And that became Stack Overflow. And it, over time, we realized it wasn't really discussion. It was very focused questions and answers. There wasn't a lot of room on the page for, let me talk about this tangential thing. It was more like, okay, is it answering the question? Is it clarifying the question? Or could it be an alternative answer to the same question? Cause there's usually more than one way to do it in programming. There's like, say, five to 10 ways.

• 13:38Speaker 01

  And one of the patterns we got into early on with Stack Overflow was there were questions where there would be like hundreds of answers. And we're like, wow, how can there be a programming question with 500, 200, 500 answers? And we looked at those and we realized those were not really questions in the traditional sense. They were discussions. It was stuff that we allowed early on that we eventually decided wasn't allowed, such as what's your favorite programming food? You know, what's the funniest programming cartoon you've seen? And we had to sort of backfill a bunch of rules about like, why isn't this allowed? Such as, is this a real problem you're facing? Like, nobody goes to work and says, wow, I can't work. Cause I don't know what the funniest programming cartoon is. So, sorry, can't compile this code now. Right? It's not a real problem you're facing in your job. So that was run rule.

• 14:20Speaker 01

  And the second, like, what can you really learn from that? It's like what I call accidental learning or Reddit style learning? Where you're just like, oh, I just browse some things and oh, wow, you know, did you know tree frogs only live three years? I mean, I just made that up. I don't know if that's true, but I didn't really set out to learn that. I don't need to know that, right? It's accidental learning. It was more intentional learning. Where you're like, okay, I have a problem and I want to learn about stuff around this problem having, right? And it could be theory, it could be compiler theory, it could be- Other stuff, but I'm having a compiler problem, hence I need to know the compiler theory, that aspect of it that gives me the, the, gets me to my answer, right? So kind of a directed learning. So we had to backfill all these rules as we sort of figured out what the heck it was we were doing. And the system came very strict over time and a lot of people still complain about that. And I wrote

• 15:03Speaker 01

  uh my latest blog entry, uh what does Stack Overflow want to be, want to be?

• 15:06Lex Fridman?

  When it grows up, celebrating the 10 year anniversary, yeah.

• 15:09Speaker 01

  Yeah. So 10 years and it, the system has trended towards strictness. There's a variety of reasons for this. One is people don't like to see other people get reputation for stuff as they view, they view as frivolous, which I can actually understand because if you saw a programmer got like 500 upvotes for funniest programming cartoon or funniest comment they had seen in code. It's like, well, why do they have that reputation? Is it because they wrote the joke? Probably not. I mean, if they did, maybe, or the cartoon, right? They're getting a bunch of reputation based on someone else's work. It's not even like programming. It's just a joke, right? It's a related to program. So you, you begin to resent that. You're like, well, that's not fair. And it isn't. At some level, they're correct. I mean, I empathize because like, it's not correct to get a reputation for that versus here's a really gnarly, regular expression problem.

• 15:51Speaker 01

  And here's a really, you know, clever, insightful, you know, detailed answer laying out, oh, here's why you're seeing the behavior that you're seeing. Here, let me teach you some things about how to avoid that in the future. That's, that's great. Like, that's gold, right? You want people to get a reputation for that, not so much for, wow, look at this funny thing I saw, right?

• 16:06Lex Fridman?

  Great. So there's this very specific Q and A format and then take me through the journey towards discourse and Facebook and Twitter. So you started at the beginning that Stack Overflow evolved to have a purpose. So where does discourse? This uh passion you have for uh creating community for discussion, what, where is that? When was that born and how?

• 16:27Speaker 01

  Well, part of it is based on the realization that Stack Overflow is only good for very specific subjects where there's sort of it's, it's based on data, facts and science where answers can be kind of verified to be true. Another form of that is there's the book of knowledge, like the tome of, of knowledge that defines like whatever it is. You can refer to that book and it'll give you the answer. There has to be, it only works on subjects where there's like semi-clear answers to things that can be verified in some form. Uh now again, there's always more than one way to do it. Uh there's complete flexibility in the system around that. But where it falls down is, is stuff like poker and Lego. Like we had, if you go to stackexchange.com, we have an engine that, that tries to launch different Q and A topics, right? And people can propose uh Q and A topics.

• 17:11Speaker 01

  Sample questions and if it gets enough support within the network, we launched that Q and A site. So some of the ones we launched were poker and Lego and they did horribly, right? Because, I mean, they might still be there lingering on in some form, but it was an experiment. This is like a test, right? And some subjects work super well on the Stack Engine and some don't. But the reason Lego and poker don't work is because they're so social, really. It's not about, you know, what's the rule here in poker? It's like, well, you know, what kind of cigars do we like to smoke while playing poker? Or, you know, what's a cool set of cards to use when I'm playing poker? Or, you know, what's some strategies? Like, say I have this hand come up with some strategies I could use. It's more of a discussion around like what's happening like with Lego. You know, same thing like here's this cool Lego set I found. Look how awesome this is. And like, yeah, that's freaking awesome, right? It's not a question, right?

• 17:55Speaker 01

  There's all these social components, discussions that don't fit at all. Like, we literally have to just allow those in Stack Overflow because it's not about being social. It's about problems that you're facing in your work that you need concrete answers for, right? Like, you have a real demonstrated problem that's sort of blocking you in something. Nobody's blocked by, you know, what should I do when I have a straight flush, right? Like, it's not a blocking problem in the world. It's just an opportunity to hang out and discuss. So discourse was a way to address that and say, look, you know, discussion forum software was very, very bad. And when I came out of Stack Overflow in late 20, early 20, early 2013? Early, early 2012. It was still very, very bad. I expected it improved in the four years since I last looked, but it had not improved at all.

• 18:40Speaker 01

  And I was like, well, that's kind of terrible because I love these communities of people talking about things that they love. You know, that they're just communities of interest, right? And there's no good software for them. Like startups would come to me and say, hey, Jeff, I want to, you know, I have this startup. Here's my idea. And the first thing I would say to them is like, well, first, why are you asking me? Like, I don't really know your field, right? Not necessarily like, why aren't you asking like the community, like the people that are interested in this problem? The people that are using your product? Why aren't you talking to them? And then they'd say, oh, great idea. Like, how do I do that? And then that's when I started playing sad trombone because I realized all the software involving talking to your users, customers, audience, patrons, whatever it is, it was all really bad. You know, it was like stuff that I would be embarrassed to recommend to other people.

• 19:23Speaker 01

  And yet that's where I felt they could get the biggest and strongest, most effective input for what they should be doing with their product, right? It's from their users, from their community, right? That's what we did on Stack Overflow.

• 19:34Lex Fridman?

  So what we're talking about with forums, the

• 19:38Lex Fridman?

  What is it, the dark matter of the internet? It's still, I don't know if it's still, but for a longest time, it has some of the most passionate and fascinating discussions. And what's the usual structure? There's usually, it's linear, so it's sequential. So you're posting one after the other and there's pagingation. So it's every, there's 10 posts and you go to the next page. And that format still is used by, like I'm, we're doing a lot of research with Tesla vehicles. And there's Tesla Motors Club forum, which is extremely-

• 20:09Speaker 01

  We really wanted to run that, actually. They pinged us about it, I don't think we got it, but I really would have liked to gotten that one.

• 20:14Lex Fridman?

  But they've started before even 2012, I believe. I mean, they've been running for a long time. It's still an extremely rich source of information. So what's broken about that system? And how are you trying to fix it?

• 20:27Speaker 01

  I think there's a lot of power in, in connecting people that love the same stuff around that specific topic. Meaning Facebook's idea of connection is just any human that's related to another human, right? Like, like through friendship or, you know, any other reason. Facebook's idea of the world is sort of the status update, right? Like a friend of yours did something, ate at a restaurant, right? Whereas discussion forums traditionally around the interest graph. Like I love electric cars, specifically I love Tesla, right? Like I love the way they approached the, the problem. I love the style of the founder. I just love the, the design ethic. And there's a lot to like about Tesla. I don't know if you saw the oatmeal, he did a whole love comic to Tesla. And it was actually kind of cool because I learned some stuff.

• 21:10Speaker 01

  He was talking about how great Tesla cars were specifically, like how they were built differently. And he went into a lot of great detail that was really interesting. And to me, that oatmeal post, if you read it, is the genesis of pretty much all interest communities. I just really love this stuff. So for me, for example, there's yoyos, right? Like I'm into the yoyo communities and there's, these interest communities are just really fascinating to me. And I feel more connected to the yoyo communities than I do to, you know, friends that I don't see that often, right? Like to me, the, the powerful thing is the interest graph. And Facebook kind of dabbles in the interest graph. I mean, they have groups, you can sign up for groups and stuff, but it's really about the relationship graph. Like this is my coworker, this is my relative, this is my friend. But not so much about the interest. So I think that's the, the linchpin of which forums and communities are built on that I personally love.

• 21:55Speaker 01

  Like I, I, like I said, leadership is about passion, right? And being passionate about stuff is, is a really valid way to look at the world. And I think it's a way-

• 22:05Speaker 01

  A lot of stuff in the world gets done. Like, I once had someone describe me as, he's like, Jeff, you're a guy who, you just get super passionate about a few things at a time, and you just go super deep in those things. And I was like, oh, that's kind of right. That's kind of what I do. I'll get into something and just be super into that for a couple of years or whatever, and just learn all I can about it and go super deep in it. And that's how I enjoy experiencing the world, right? Like, not being shallow on a bunch of things, but being really deep on a few things that I'm interested in. So forums kind of unlock that, right? And, you know, you don't want a world where everything belongs to Facebook, at least I don't. I want a world where communities can kind of own themselves, set their own norms, set their own rules, control the experience, because community is also about ownership, right? Like, if you're meeting at the Barnes & Noble every Thursday, and Barnes & Noble

• 22:48Speaker 01

  says, "Get out of here, you guys don't buy enough books," well, you know, you're kind of hosed, right? Barnes & Noble owns you, right? Like, you can't... But if you have your own meeting space, you know, your own clubhouse, you can set your own rules, decide what you want to talk about there, and just really generate a lot better information than you could, like, hanging out at Barnes & Noble every Thursday at 3:00 PM, right? So that's kind of the vision of Discourse, is a place where it's fully open source, you can take the software, you can install it anywhere, and, you know, you and a group of people can go deep on whatever it is that you're into. And this works for startups, right? Startups are a group of people who go super deep on a specific problem, right? And they want to talk to their community, and it's like, well, install Discourse, right? That's what we do at Discourse, that's what I did at Stack Overflow. I spent a lot of

• 23:29Speaker 01

  time on Meta Stack Overflow, which is our internal, well, public community feedback site, and just experiencing what the users were experiencing, right? Because they're the ones doing all the work in the system, and they had a lot of interesting feedback. And there's that 90/10 rule, like, 90% of the feedback you get is not really actionable for a variety of reasons. It might be bad feedback, it might be crazy feedback, it might be feedback you just can't act on right now. But there's 10% of it that's like, gold. It's like, literally gold and diamonds, where it's like, feedback of really good improvements to your core product, that are not super hard to get to and actually make a lot of sense. And my favorite is about 5% of those stuff I didn't even see coming. It's like, oh my God, I never even thought of that. But that's a brilliant idea, right? And I can point to so many features of Stack Overflow that we derive from Meta Stack

• 24:11Speaker 01

  Overflow feedback, and Meta Discourse, right? Same exact principle of Discourse, you know? We're getting ideas from the community. I was like, oh my God, I never thought of that. But that's fantastic, right? Like, I love that relationship with the community.

• 24:22Lex Fridman?

  From having built these communities, what have you, what have you learned about? What's the process of getting a critical mass of members in a community? Is it luck, skill, timing, persistence? What is, is it the tools, like discourse that empower that community? What's the key aspect of starting for one guy or gal and then building it to two and then 10 and 100 and 1,000 and so on?

• 24:45Speaker 01

  I think we're starting with an N of one. I mean, I think it's persistence and, and also you have to be interesting. Like somebody I really admire once said something that I always liked about blogging. He's like, here's how you blog. You have to have something interesting to say and have an interesting way of saying it. Right?

• 25:01Lex Fridman?

  Yeah.

• 25:02Speaker 01

  And then do that for like 10 years. So that's the genesis is like, you have to have sort of something interesting to say. That's not exactly what everyone else is saying and an interesting way of saying it, which is another way of saying kind of entertaining way of saying it. And then as far as growing it, it's like ritual, you know? Like you have to like, say you're starting a blog, you have to say, look, I'm going to blog every week, three times a week and you have to stick to that schedule. Right? Because until you do that for like several years, you're never going to get anywhere. Like it just takes years to get to where you need to get to. And part of that is having the discipline to stick with the schedule. And, and it helps again, if it's something you're passionate about, this won't feel like work. Like, I love this. I could talk about this all day, every day. Right?

• 25:42Speaker 01

  You just have to do it in a way that's interesting to other people. And then as you're growing the community, that pattern of participation within the community of like generating these artifacts and inviting other people to help you like collaborate on these artifacts. Like even in the case of blogging, like I felt in the early days of my blog, which I started in 2004, which is really the genesis of Stack Overflow. If you look at all my blog, it leads up to Stack Overflow, which was, I have all this energy in my blog, but I don't, like 40,000 people were subscribing to me. And I was like, I want to do something. And then, then I met Joel and said, hey, Joel, I want to do something. Take this ball of energy from my blog and do something. And all the people reading my blog saw that's like, oh, cool. You're involving us. You're saying, look, you're part of this community. Let's build this thing together. Like they picked the name, like we voted on the name for Stack Overflow on my blog. Like we came up and naming is super hard, first of all.

• 26:26Speaker 01

  The hardest problem in computer science is coming with a good name for stuff, right?

• 26:28Lex Fridman?

  Yep.

• 26:29Speaker 01

  But there, you can go back to my blog. There's the poll where we voted and Stack Overflow became the name of the site. And all the early beta users of Stack Overflow were, were audience of my blog plus Joel's blog, right? So we started from like, if you look at the genesis, okay, I was just a programmer who said, hey, I love programming, but I have no outlet to talk about it. So I'm just going to blog about it because I don't have enough people to work to talk to about it. Because at the time I worked at a place where, you know, programming wasn't the core output of the company. It was a pharmaceutical company and I just love this stuff, you know, to an absurd degree. So I was like, I'll just blog about it and then I'll find an audience and eventually found an audience. Eventually found Joel and eventually built Stack Overflow from that one core of, of activity, right? But it was that repetition of feeding back in, feedback from my blog comments, feedback from Joel,

• 27:13Speaker 01

  feedback from the, the early Stack Overflow community. When people see that you're doing that, they will follow along with you, right? They're like, oh, cool. You're here in good faith. You're actually, you know, not listening to everything because that's impossible. That's impossible, but you're actually, you know, weighting our feedback in what you're doing because, and why wouldn't I? Because who does all the work on Stack Overflow? Me? Joel? No, it's the other programmers that are doing all the work. So you've got to have some respect for that. And then, you know, discipline around, look, you know, we're trying to do a very specific thing here on Stack Overflow. We're not trying to solve all the world's problems. We're trying to solve this very specific Q and A problem in a very specific way. Not because we're jerks about it, but because these strict set of rules help us get really good results, right?

• 27:54Speaker 01

  And programmers, that's an easy sell for the most part because programmers are used to dealing with ridiculous systems of rules like constantly. That's basically their job. So they're, they're very, oh yeah, super strict system of rules that lets me get what I want. That's programming, right? That's what Stack Overflow is, so.

• 28:09Lex Fridman?

  So you're making it sound easy, but in 2004, let's go back there. In 2004, you started the blog, Coding Horror. Was it called that at the beginning, at the very beginning?

• 28:18Speaker 01

  It was. One of the smart things I did, it's from a book by Steve McConnell, Code Complete, which is one of my favorite programming books. Still probably my number one programming book for anyone to read.

• 28:27Speaker 01

  One of the smart things I did back then, I don't always do smart things when I start stuff. I contacted Stephen and said, hey, I really like this, uh, it was a sidebar illustration indicating danger in code, right? Coding Horror was like, watch out. And I love that illustration because it spoke to me because I saw that illustration go, oh my God, that that's me like I'm always my own worst enemy. Like that's the key insight in programming is every time you write something, think, how am I going to screw myself? Because you will constantly, right? So that that icon was like, oh yeah, I need to constantly hold that mirror up and look and say, look, you're very fallible. You're going to screw this up. Like, how can you build this in such a way that you're not going to screw it up later? Like, how can you get that discipline around making sure at every step, I'm thinking through

• 29:10Speaker 01

  all the things that I could do wrong, or that other people could do wrong? Because that is actually how you get to be a better programmer a lot of times, right? So that sidebar illustration, I loved it so much. And I wrote Steve before I started my blog and say, hey, can I have permission to use this? Because I just really like this illustration. And Steve was kind enough to let give me permission to do that. And she just continues to give me permission. So yeah.

• 29:28Lex Fridman?

  Really? That's awesome. But in 2004, you started this blog. You know, you look at Stephen King, his book on writing, or Steven Pressfield, War of Art book. I mean, it seems like writers suffer. I mean, it's a hard process of writing, right? It's like

• 29:47Speaker 01

  There's a lot of, there's gonna be suffering. I mean, I won't kid you like, well, the work is suffering, right? Like, doing the work, like even when you're every week, you're like, okay, that blog post wasn't very good. Or, you know, people didn't like it, or people said disparaging things about it. You have to like, have the attitude is like, you know, no matter what happens, I want to do this for me, right? It's not about you, it's about me. I mean, in the end, it is about everyone, because this is how good work gets out into the world. But you have to be pretty strict about saying like, you know, I'm selfish in the sense that I have to do this for me. You know, you mentioned Stephen King, like his book on writing. But like, one of the things I do, for example, when when writing is like, I read it out loud. One of the best pieces of advice for writing anything is read it out loud, like multiple

• 30:28Speaker 01

  times, and make it sound like you're talking, because that is the goal of good writing. It should sound like you said it with with slightly better phrasing, because you have more time to think about what you're saying. But like, it should sound natural when you say it. And I think that's probably the single best writing advice I can give anyone. Just just read it over and over out loud. Make sure it sounds like something you would normally say. And it sounds good.

• 30:48Lex Fridman?

  And what's your process of writing? So there's usually a pretty good idea behind the blog post.

• 30:54Speaker 01

  So ideas, right. So I think you gotta have the concept that There's so many interesting things in the world. Like, I mean, my god, the world is amazing, right? Like, it's, you can never write about everything that's going on because it's so incredible. But if you can't come up with, like, let's say, one interesting thing per day to talk about, then you're not trying hard enough because the world is full of just super interesting stuff. And one great way to like mine stuff is go back to old books because they bring up old stuff that's still super relevant. And I did that a lot because I was like reading classic programming books and a lot of the early blog posts were like, oh, I was reading this programming book and they brought this really cool concept and I want to talk about it some more. And you get the, I mean, you're not claiming credit for that idea, but it gives you something interesting to talk about that's kind of evergreen, right? Like, you don't have to go, what should I talk

• 31:37Speaker 01

  about? So we'll just go dig up some old classic programming books and find something that, oh, wow, that's interesting. Or how does that apply today? Or what about X and Y? Or compare these two concepts?

• 31:46Lex Fridman?

  So pull a couple of sentences from that book and then sort of play off of it, almost agree or disagree that so in 2007, you wrote that you were offered a significant amount of money to sell the blog. You chose not to. What were all the elements you were thinking about? Because I'd like to take you back. It seems like there's a lot of nonlinear decisions you made through life. So what was that decision like?

• 32:11Speaker 01

  Right. So I, one of the things I love is the choose your own adventure books, which I loved as a kid. And I feel like they're early programmer books because they're, they're all about if then statements, right? If this, then this. And they're also very, very unforgiving. Like, there's all these sites that map the, the, the classic choose your own adventure books and how many outcomes are bad. There's a lot of bad outcomes. So part of the game is like, oh, I got a bad outcome. Go back one step, go back one further step. Like, how did I get here? Right? Like, it's a sequence of decisions. And this is true of life, right? Like, every decision is a sequence, right? Individually, any individual decision is not necessarily right or wrong, but they, they lead you down a path, right? So I do think there's some truth to that. So this particular decision, the blog had gotten fairly popular. There's a lot of RSS readers that I discovered. And this guy contacted me out of the, out of

• 32:56Speaker 01

  the blue from this like bug tracking company. He's like, oh, I really want to buy your blog for like, I think it was around, it was a hundred thousand dollars, it might have been like 80,000, but it was, it was a lot, right? Like, and that's, you know, at the time, like, I would have a year's worth of salary all at once. So I didn't really think about like, well, you know, and I remember talking to people at the time, it's like, wow, that's a lot of money. But then I really liked my blog, right? Like, do I want to sell my blog? Because it wouldn't really belong to me anymore at that point. And One of the guidelines that I like to, I don't like to give advice to people a lot, but one of the pieces of advice I do give, because I do think it's really true and it's generally helpful, is whenever you're looking at a set of decisions like, "Oh, gosh, should I do A, B, or C?" You've got to pick the thing that's a little scarier in that list.

• 33:38Speaker 01

  Because not, you know, not like jump off a cliff scary, but the thing that makes you nervous. Because if you pick the safe choice, it's usually you're not really pushing. You're not pushing yourself. You're not choosing the thing that's going to help you grow. So for me, the scarier choice was to say no. I was like, "Well, no, let's just see where this is going." Right? Because then I own it. I mean, it belongs to me. It's my thing. And I can just take it and to some other logical conclusion, right? Because imagine how different the world would have been had I said yes and sold the blog. It's like there probably wouldn't be Stack Overflow. You know, a lot of other stuff would have changed. So for that particular decision, I think it was that same rule, like what scares me a little bit more?

• 34:13Lex Fridman?

  Do the thing that scares you.

• 34:14Speaker 01

  Yeah.

• 34:14Lex Fridman?

  So speaking of which, startups, I think there's specifics and more general questions that a lot of people would be interested in. You've started Stack Overflow, you've started Discourse. So what's the, you know, there's one, two, three guys, whatever it is in the beginning. What was that process like? Do you start talking about it? Do you start programming? Do you start, like, where's the birth and the catalyst that actually?

• 34:41Speaker 01

  Well, I can talk about it in the context of both Stack Overflow and Discourse. So I think the key thing initially is there is a problem. Something, there's some state of the world that's unsatisfactory to the point that like you're upset about it. Right? Like, in that case, it was Experts Exchange. I mean, Joel's original idea, because I approached Joel, I was like, "Look, Joel, I have all this energy behind my blog. I want to do something. I want to build something, but I don't know what it is." Because I'm not, I'm honestly not a good idea person. I'm really not. I'm like the execution guy. I'm really good at execution, but I'm not good at like blue-sky-ing ideas. It's not my forte, which is another reason why I like the community feedback. Because they blue-sky all day long for you, right? So when I can just go in and cherry pick a blue-sky idea from the community, even if I have to spend three hours reading to get one good idea, it's worth it, man. But anyway, so the idea from Joel was, "Hey, Experts Exchange." It's got great data, but the experience is hideous, right? It's trying to trick you. It feels like used car salesman.

• 35:26Speaker 01

  It's just bad. So I was like, oh, that's awesome. It feeds into community. It feeds into like, you know, we can make a creative commons. So I think the core is to have a really good idea that you feel very strongly about in the beginning, that like, there's a wrong in the world that we will, an injustice that we will right through the process of building this thing. For Discourse, it was like, look, there's no good software for communities to just hang out and like, do stuff, right? Like whether it's problem solving, startup, whatever. Forums are such a great building block of online community and they're hideous. They were so bad, right? It was embarrassing. Like, I literally was embarrassed to be associated with this software, right? I was like, we have to have software that you can be proud of. It's like, this is competitive with Reddit. This is competitive with Twitter. This is competitive with Facebook, right? I would be proud to have the software on my site.

• 36:08Speaker 01

  So that was the genesis of Discourse, was feeling very strongly about, um, there needs to be a good solution for communities. So that's step one, genesis of an idea you feel super strongly about, right? And then people galvanize around the idea. Like Joel was already super excited about the idea. I was excited about the idea. So with the forum software, I was posting on Twitter, I had researched, as part of my research, I start researching the problem, right? And I found a game called Forum Wars, which was a parody of forum. It's still very, very funny of like forum behavior circa like, I would say 2003. It's aged some, right? Like, the behavior's a little different in there of Twitter, but it was awesome. It was very funny and it was like a game, it was like an RPG and it had a forum attached to it. So it was like a game about forums with a forum attached. I was like, this is awesome, right?

• 36:53Speaker 01

  This is so cool. And the founder of that company, or that project, it wasn't really a company, contacted me, this guy Robin Ward from Toronto, said, hey, you know, I saw you've been talking about forums and like, I really love that problem space. It's like, I'd still love to build really good forum software because I don't think anything out there is any good. And I was like, awesome. At that point, I was like, we're starting a company. Because like, I couldn't have whooshed for a better person to walk through the door and say, I'm excited about this too. Same thing with Joel, right? I mean, Joel is a legend in the industry, right? So when he walked through, he said, I'm excited about this problem. I was like, me too, man. We can do this, right? So that, to me, is the most important step. It's like having an idea you're super excited about and another person, a co-founder, right? Because again, you get that dual leadership, right? Of like, am I making a bad decision? Sometimes it's nice to have checks of like, is this a good idea? I don't know, right?

• 37:38Lex Fridman?

  So those are the crucial seeds, but then starting to build stuff. Whether it's you programming or somebody else.

• 37:44Speaker 01

  So there's tons of research. There's tons of research, like what's out there that failed? Cause a lot of people look at successes. Oh, look at how successful X is. Everybody looks at the successes. Those are boring. Show me the failures, because that is what's interesting. That's where people were experimenting. That's where people were pushing, but and they failed, but they probably failed for reasons that weren't directly about the quality of their idea.

• 38:04Lex Fridman?

  Right?

• 38:05Speaker 01

  So look at all the failures. Don't just look what everybody looks at, which is like, oh gosh, look at all these successful people. Look at the failures. Look at the things that didn't work. Research the entire field. And so that's the research that I was doing that led me to Robin, right? Was that? And then when we, for example, when we did Stack Overflow, we're like, okay, well, I really like elements of voting and digging Reddit. I like the Wikipedia. Everything's up to date. Nothing is like an old tombstone that like has horrible out of date information. We know that works. Wikipedia is an amazing resource. Blogging, the idea of ownership is so powerful, right? Like, oh, I Joe wrote this and look how good Joe's answer is, right? Like all these concepts were rolling together, researching all the things that were out there that were working and why they were working and trying to like fold them into that, again, that Frankenstein's monster of what Stack Overflow is.

• 38:50Speaker 01

  And by the way, that wasn't a free decision because there's still a ton of tension in the Stack Overflow system. There's reasons people complain about Stack Overflow because it's so strict, right? Why is it so strict? Why are you guys always closing my questions? It's because there's so much tension that we built into the system around like trying to get good, good results out of the system. And, you know, it's not a free, that stuff doesn't come for free, right? It's not like we all have perfect answers and nobody will have to get their feelings hurt or nobody will have to get downvoted like that. It doesn't work that way, right? Like.

• 39:21Lex Fridman?

  So this is an interesting point and a small tangent. You're right about anxiety. So I've posted a lot of questions and written answers on Stack Overflow. On the questions side, usually go to something very specific to something I am working on. This is something you talk about that really the goal of Stack Overflow isn't about, is to write a question not, that's not about you. It's about. The question that will help the community in the future.

• 39:51Speaker 01

  Right. That's a tough sell, right? Because people are like, well, you know, I don't really care about the community. What I care about is my problem.

• 39:56Lex Fridman?

  My problem.

• 39:57Speaker 01

  And that's fair, right? It's sort of that, again, that tension, that balancing act of we want to help you, but we also want to help everybody that comes behind you, right? The long line of people are going to come up and say, oh, I kind of have that problem too, right? And if nobody's ever going to come up and say, I have this problem too, then that question shouldn't exist in Stack Overflow because the question is too specific. And even that's tension, right? How do you judge it? How do you know that nobody's ever going to have this particular question again? So there's a lot of tension in the system.

• 40:22Lex Fridman?

  Do you think that anxiety of asking the question, the anxiety of answering that tension is inherent to programmers, is inherent to this kind of process? Or can it be improved? Can it be happy land where that tension is not quite so harsh?

• 40:41Speaker 01

  I don't think Stack Overflow can totally change the way it works. One thing they are working on finally is the Ask page had not changed since 2011. I'm still kind of bitter about this because I feel like you have a Q and A system. And what are the core pages in a Q and A system? Well, first of all, the question, all the answers and also the Ask page, particularly when you're a new user or someone trying to ask a question, that's the point at which you need the most help. And we just didn't adapt with the times. But the good news is they're working on this, from what I understand. And it's going to be a more wizard-based format. And you could envision a world where as part of this wizard-based program, when you're asking a question, so okay, come up with a good title. What are good words to put in the title? One word that's not good to put in the title is problem, for example. I have a problem. Oh, you have a problem. Okay.

• 41:23Speaker 01

  A problem. That's great, right? Like, you need specifics, right? Like, so it's trying to help you make a good question title, for example. That step will be broken out, all that stuff. But one of those steps in that wizard of asking could say, hey, I'm a little nervous, you know, I've never done this before. Can you put me in a queue for like special mentoring, right? You could opt in to a special mentor. I think that would be fantastic. Like, I don't have any objection to that at all in terms of being an opt-in system, because there are people that are like, you know, I just want to help them. I want to help a person no matter what. I want to go above and beyond. I want to spend like hours with this person. It depends what their goals are, right?

• 41:58Lex Fridman?

  It's a great idea.

• 41:58Speaker 01

  Who am I to judge, right? So that's fine. It's not precluded from happening. But there's a certain big city ethos that we started with of like, look, we're New York City. You don't come to New York City and expect them to be, oh, welcome to the city, Joe. How's it going? Come on in. Let me show you around. That's not how New York City works, right? I mean, and, you know, again, New York City has a reputation for being rude, which I actually don't think it is, having been there fairly recently. It's not rude. People are just like going about their business, right? And they're like, look, I have things to do. I'm busy. I'm a busy professional, as are you. And since you're a busy professional, certainly when you ask a question, you're going to ask the best possible question, right? Because you're a busy professional and you would not accept anything less than a very well-written question with a lot of detail about why you're doing it, what you're doing, what you researched, what you found, right? Because you're a professional like me, right?

• 42:43Speaker 01

  And this rubs people sometimes the wrong way. And I don't think it's wrong to say, look, I don't want that experience. I want just a more chill place for beginners. And I still think Stack Overflow is not, was never designed for beginners, right? There's this misconception that, you know, even Joel says sometimes, oh, yeah, Stack Overflow for beginners. And I think if you're a prodigy, it can be.

• 43:04Lex Fridman?

  Right.

• 43:04Speaker 01

  But that's not really representative, right? Like, I think as a beginner, you want a totally different set of tools. You want like live screen sharing, live chat. You want access to resources. You want a playground, like a playground you can experiment in and like test and all the stuff that we just don't give people because that was never really the, the audience that we were designing Stack Overflow for. That doesn't mean it's wrong. And I think it would be awesome if there was a site like that on the internet or if Stack Overflow says, hey, you know, we're going to start doing this. That's fine, too. You know, I'm not there. I'm not making those decisions. But I do think the pressure, the tension that you described is there for people to be, look, I'm a little nervous because I know I got to do my best work, right?

• 43:41Lex Fridman?

  The other one is something you talk about, which is also really interesting to me, is duplicate questions or it's a, it's a really difficult problem that you highlight.

• 43:53Speaker 01

  Super problem. It's super hard.

• 43:54Lex Fridman?

  Like you could take one little topic and you could probably write 10, 20, 30 ways of asking about that topic and they will be all different. I don't know if there should be one page that answers all of it. Is there a way that Stack Overflow can help?

• 44:13Lex Fridman?

  Disambiguate, like, separate these duplicate questions or connect them together? Or is it a totally hopeless, difficult, impossible task?

• 44:21Speaker 01

  I think it's a very, very hard computer science problem. And partly because people are very good at using completely different words. It always amazed me on Stack Overflow, you'd have two questions that were functionally identical, and one question had like zero words in common with the other question. I'm like, oh, my God. From a computer science perspective, how do you even begin to solve that? And it happens all the time. People are super good at this, right? Accidentally at asking the same thing in like in 10, 20 different ways. And the other complexity is we want some of those duplicates to exist because if there's five versions with different words, have those five versions point to the one centralized answer, right? It's like, OK, this is duplicate, no worries. This, here's, here's the answer that you wanted over here on this, this, this, you know, the, the prime example that we want to have, rather than having 10 copies of the question and the answer.

• 45:06Speaker 01

  Because if you have 10 copies of the question and answer, this also devalues the reputation system, which programmers hate, as I previously mentioned. You're getting a reputation for an answer that somebody else already gave. It's like, well, it's an answer, but somebody else already gave that answer. So why are you getting a reputation for the same answer as the other guy who gave it four years ago? People get offended by that, right? So the reputation system itself adds tension to the system. In that the people who have a lot of reputation become very incentivized to enforce the reputation system. And for the most part, this is good. I know it sounds weird, but for most part, it's like, look, strict systems, I think to use Stack Overflow, you have to have the idea that, OK, strict systems ultimately work better. And I do think in programming, you're familiar with loose typing versus strict typing, right? The idea that you can declare a variable, not declare a variable, rather, just start

• 45:49Speaker 01

  using a variable and, OK, I see it's implicitly an integer, bam, awesome. Duck equals 5. Well, duck is now an integer 5, right? And you're like, cool, awesome, simpler, right? Why would I want to worry about typing? And for a long time, like, in the Ruby community, they're like, yeah, this is awesome. Like, you just do a bunch of unit testing, which is testing your program's validity after the fact, to catch any bugs that, that, that strict typing of variables would have caught. And now you have this thing called TypeScript from Microsoft, from the guy who built C# Anders, who's one of the greatest minds in, in software development, right? Like, in terms of language design. And says, no, no, no, we want to bolt on a strict type system to JavaScript because it makes things better. And now everybody's like, oh, my God, we, we deployed TypeScript and found 50 latent bugs that we didn't know about, right? Like, this is super common. So.

• 46:32Speaker 01

  I think there is a truth in programming that strictness, it's not the goal. We're not saying be super strict because strictness is correct. No, it's no, no. Strictness produces better results. That's what I'm saying, right? So strict typing of variables, I would say you almost universally have consensus now is basically correct, should be that way in every language, right? Duck equals five should generate an error because you know, you didn't declare, you didn't tell me that duck was an integer, right? That's a bug, right? Or maybe you mistyped, you typed deck, right? Instead of duck, right? You never know, this happens all the time, right? So with that in mind, I will say that the strictness of the system is correct. Now, that doesn't mean cruel, that doesn't mean mean, that doesn't mean angry, it just means strict, okay? So I think where there's misunderstanding is in people get cranky, right?

• 47:16Speaker 01

  Like another question you asked is like, why are programmers kind of mean sometimes? Well, who do programmers work with all day long? So I have a theory that if you're at a job and you work with assholes all day long, what do you eventually become?

• 47:29Lex Fridman?

  An asshole.

• 47:30Speaker 01

  An asshole. And what is the computer except the world's biggest asshole? Because the computer has no time for your bullshit. The computer, the minute you make a mistake, everything is crashing down, right? One semicolon has crashed space missions, right? So that's normal. So you begin to internalize that. You begin to think, oh, my coworker, the computer is super strict and kind of a jerk about everything. So that's kind of how I'm gonna be because I work with this computer and I have to exceed to its terms on everything. So therefore you start to absorb that and you start to think, oh, well, being really strict arbitrarily is really good. An error of error code 56249 is a completely good error message because that's what the computer gave me, right? So you kind of forget to be a person at some level.

• 48:14Speaker 01

  And you know how they say great detectives internalize criminals and kind of are criminals themselves, like this trope of the master detective is good because he can think like the criminal. Well, I do think that's true of programmers, really good programmers think like the computer because that's their job. But if you internalize it too much, you become the computer and you come a kind of become a jerk to everybody because that's what you've internalized.

• 48:37Lex Fridman?

  You're almost not a jerk, but you have no patience for a lack of strictness, as you said.

• 48:42Speaker 01

  It's not out of a sense of meanness. It's accidental, but I do believe it's an occupational hazard of being a programmer is you start to behave like the computer. You're very unforgiving. You're very terse. You're very, oh, wrong, incorrect, move on. It's like, well, can you help me? Like, what could I do to fix? No, wrong. Next question. Right? Like, that's normal for the computer, right? Just fail, next, right? Like, I don't know if you remember in Saturday Night Live, like in the 90s, they had this character who was an IT guy.

• 49:09Lex Fridman?

  Yeah.

• 49:09Speaker 01

  The move guy. Move.

• 49:11Lex Fridman?

  Move. Was that Jimmy Fallon? No, no.

• 49:14Speaker 01

  Can't remember.

• 49:15Lex Fridman?

  Who played him? Okay. Yeah, I remember move.

• 49:17Speaker 01

  Right. He had no patience for you.

• 49:19Lex Fridman?

  It might have been Mad TV, actually.

• 49:21Speaker 01

  Was it Mad TV? Might have been, might have been. But anyway, that was the, that's always been the perception, right? You start to behave like the computer. It's like, oh, you're wrong, out of the way, you know?

• 49:30Lex Fridman?

  You've written so many blog posts about programming, about programs, programming, programmers. What do you think makes a good, let's start with what makes a good solo programmer?

• 49:44Speaker 01

  Well, I don't think you should be a solo programmer. I think to be a good solo programmer, it's kind of like what I talked about, well, not on mic, but one of the things, John Carmack, one of the best points he makes in the book Masters of Doom, which is a fantastic book, and anybody listening to this who hasn't read it, please read it. It's such a great book. Is that at the time, they were working on stuff like Wolfenstein and Doom, like, they didn't have the resources that we have today. They didn't have Stack Overflow. They didn't have Wikipedia. They didn't have like discourse forums. They didn't have places to go to get people to help them, right? They had to work on their own. And that's why it took a genius like Carmack to do this stuff, because you had to be a genius to invent from first principles. A lot of the stuff he was, he was like, the hacks he was coming up with were genius, right? Genius level stuff. But you don't need to be a genius anymore.

• 50:29Speaker 01

  And that means not working by yourself. You have to be good at researching stuff online. You have to be good at asking questions. Really good questions that are really well researched, which implies, oh, I went out and researched for three hours before I wrote this question. It's like, that's what you should be doing. Because that's what's going to make you good, right? To me, this is the big difference between programming in like the 80s versus programming today is like you, you kind of had to be by yourself back then. Like, where would you go for answers? I remember in the early days, when I was a learning Visual Basic for Windows, like I would call the Microsoft helpline on the phone when I had like a program, because I was like, I don't know what to do. So I would like go and call and they had these huge phone mags and like, can you imagine how alien that is now? Like, who would do that? Right? Like, that's crazy. So. There was just nowhere else to go when you got stuck, right? Like, I had the books that came with it.

• 51:14Speaker 01

  I read those, studied those religiously. I just saw a post from Steve Sinofsky that said this C++ version 7 came with like 10,000 pages of written material. Because where else were you gonna figure that stuff out? Go to the library? I mean, you didn't have Wikipedia, you didn't have, you know, Reddit? You didn't have anywhere to go to answer these questions.

• 51:35Lex Fridman?

  So you've talked about through the years, basically not having an ego and not thinking that you're the best programmer in the world. So always kind of just looking to improve, to become a better programmer than you were yesterday. So how have you changed as a programmer and as a thinker, designer around programming over the past, what is it, 15 years, really of being a public figure?

• 52:04Speaker 01

  I would say the big insight that I had is eventually, as a programmer, you have to kind of stop writing code to be effective, which is kind of disturbing. Because you really love it. But you realize like being effective at programming, at programming in the general sense, doesn't mean writing code. And a lot of times, you can be much more successful by not writing code than writing code in terms of just solving the problems you have. Essentially, hiring people that are really good and like setting them free and like giving them basic direction, right? Like on strategy and stuff. Because a lot of the problems you encounter aren't necessarily solved through like really gnarly code, they're solved by conceptual solutions, which can then be turned into code. But are you even solving the right problem?

• 52:44Speaker 01

  I mean, so I would say for me, the main insight I have is to succeed as a programmer, you eventually kind of stop writing code. That's gonna sound discouraging probably to people hearing, but I don't mean it that way. What I mean is that you're coding in a higher level language. Eventually, like, okay, so we're coding in assembly language, right? That's the beginning, right? You're hardcoded to the architecture. Then you have stuff like C where it's like, wow, we can abstract across the architecture, you can write code, I can then compile that code for ARM or, you know, whatever, you know, x86 or whatever else is out there. And then even a higher level than that, right? Like, you're looking at like Python, Ruby, interpreted languages. And then, to me, as a programmer, like, okay, I want to go even higher. I want to go higher than that. How do I abstract higher than the language? It's like, well, you abstract in spoken language and written language, right?

• 53:27Speaker 01

  Like, you're sort of inspiring people to get things done, giving them guidance, like, what if we did this? What if we did this? You're writing in the highest level language that there is, which is, for me, English, right? Whatever your spoken language is. So. It's all about being effective, right? And I think Patrick McKenzie, Patio11 on Hacker News and works at Stripe, has a great post about this of how calling yourself a programmer is a career-limiting move at some level, once you get far enough from your career. And I really believe that. And again, I apologize if this is sound discouraging. I don't mean it to be, but he's so right. Because all the stuff that goes on around the code, like the people, like, that's another thing, if you look at my early blog entries, is about, wow, programming is about people more than it's about code, which doesn't really make sense, right?

• 54:12Speaker 01

  But it's about, can these people even get along together? Can they understand each other? Can you even explain to me what it is you're working on? Are you solving the right problem? Peopleware, right? Another classic programming book, which, again, up there with Code Complete, please read Peopleware. It's that software is people, right? People are the software first and foremost. So, a lot of the skills that I was working on early in the blog were about figuring out the people parts of programming, which were the harder parts. The hard part of programming, once you get to a certain skill level in programming, you can pretty much solve any reasonable problem that's put in front of you. You're not writing algorithms from scratch, right? That just doesn't happen. So, any sort of reasonable problem put in front of you, you're gonna be able to solve. But what you can't solve is, our manager is a total jerk. You cannot solve that with code. That is not a code-solvable problem.

• 54:56Speaker 01

  And yet, that will cripple you. Way more than, oh, we had to use this stupid framework I don't like, or, you know, Sam keeps writing bad code that I hate, or, you know, Dave is off there in the wilderness writing god knows what, right? These are not your problems. Your problem is your manager, or a coworker, is so toxic to everybody else in your team that, like, nobody can get anything done. Because everybody's so stressed out and freaked out, right? These are the problems that you have to attack.

• 55:19Lex Fridman?

  Absolutely. And so, as you go to these higher-level abstractions, as you've developed as a programmer to higher, higher-level abstractions, and go into natural language, you're also the guy who kind of preached, you know, building it, you know, diving in and doing it, and like, learn by doing.

• 55:37Speaker 01

  Yes.

• 55:38Lex Fridman?

  Do you, do you worry that as you get to higher, higher-level abstractions, you lose track? Of the lower level of just building is like, do you worry about that? You know, even not maybe now, but 10 years from now, 20 years from now?

• 55:56Speaker 01

  Well, no, I mean, there is always that paranoia around, oh, gosh, I don't feel that's valuable since I'm not writing code. But for me, like when we started the discourse project, it was Ruby, which I didn't really know Ruby. I mean, as you pointed out, and this is another valuable observation from Stack Overflow, you can be super proficient, for example, C sharp, which I was working in, that's what we built Stack Overflow and still is written in, and then switch to Ruby and you're a newbie again, right? Like, but, but you have the framework. I know what a for loop is. I know what recursion is. I know, you know, what a stack trace is, right? Like, I have all the fundamental concepts to be a programmer. I just don't know Ruby. So I'm still on a higher level. I'm not like a beginner beginner, like you're saying. I'm just like, I need to apply my programming concepts I already know to Ruby.

• 56:35Lex Fridman?

  Well, so there's a question that's really interesting. So looking at Ruby, how do you go about learning enough that your intuition can be applied?

• 56:43Speaker 01

  Well, that's the thing. That's what I was trying to get to is like, what I realized, clearly when I started with just me and Robin, I realized if I bother Robin, I am now costing us productivity, right? Every time I go to Robin, rather than building the, the, our first alpha version of discourse, he's now answering my stupid questions about Ruby. Is that a good use of his time? Is that a good use of my time? And the answer to both of those was resoundingly no, right? Like, we were getting to an alpha and it was pretty much just, okay, we'll hire more programmers, right? Like, we eventually hired Neil, and then eventually Sam, who came in as a co-founder.

• 57:18Speaker 01

  Actually, it was Sam first, then Neil later. But the answer to the problem is just hire other competent programmers. It's not like teach, now I shall pull myself up by my bootstraps and learn Ruby. But at some point, writing code becomes a liability to you in terms of getting things done. There's so many other things that go on in the project, like building the prototype. Like, you mentioned, like, well, how do you, if you're not writing code, how does everybody keep focused on like, what, what are we building? Well, first, basic mockups and research, right? Like, what, what do we even want to build? There's a little bit of that that goes on. But then very quickly, you get to the prototype stage, like build a prototype, let's iterate on the prototype really, really rapidly. And that's what we did with discourse. And that's what we demoed to get our seed funding for discourse was the, the alpha version of discourse that we had running and ready to go. And it was very, it was bad. I mean, it was, I'll just tell you, it was bad.

• 58:02Speaker 01

  I have, we have screenshots of it. And I'm just like embarrassed to look at it now. But it was the prototype. We were figuring out like, what's working, what's not working? Because there's such a broad gap between, between.

• 58:13Speaker 01

  The way you think things will work in your mind or even on paper and the way they work once you sit and live in the software, like actually spend time living and breathing on software, so different. So my philosophy is get to a prototype and then what you're really optimizing for is speed of iteration, like how you can turn the crank, how quickly can we iterate? That's the absolutely critical metric of any software project. And I had a tweet recently that people liked and I totally, this is so fundamental to what I do is like, if you want to measure the core competency of any software tech company, it's the speed at which somebody can say, hey, we really need this word in the product changed to this word, right? Because it will be more clear to the users, like what, like instead of respond, it's reply or something. But there's some, from the conception of that idea to how quickly that single word

• 58:56Speaker 01

  can be changed in your software and rolled out to users, that is your life cycle. That's your health, your heartbeat. If your heartbeat is like super slow, you're basically dead. No, seriously, like if it takes two weeks or even a month to get that single word changed, there was, oh my God, this is a great idea. That word is so much clearer. I'm talking about like a super, like everybody's on board for this change. It's not like, let's just change a word because we're bored. It's like, this is an awesome change. And then it takes, you know, months to roll out. It's like, well, you're dead. Like you can't iterate, you can't, how are you going to do anything, right? Like, so anyway, about the heartbeat, it's like get the prototype and then iterate on it. That's, that's what I view as like the central tenet of some modern software development.

• 59:35Lex Fridman?

  That's fascinating you put it that way. It's actually, so I work in, I build autonomous vehicles and when you look at what maybe compare Tesla to most other automakers, the psych, the whatever, the heartbeat for Tesla is literally days now in terms of they can, over the air, deploy software updates to all their vehicles, which is markedly different than every other automaker, which takes years to update a piece of software. And so, and that's reflected in everything that's, the final product, that's reflected in really how slowly they adapt to the times.

• 1:00:13Speaker 01

  And to be clear, I'm not saying being a hummingbird is the goal either. It's like, you don't want a heartbeat that's like so fast, it's like you're, you're wing, you know, you're just freaking out. But like, it is a measure of health. You should have a healthy heartbeat. For people listening to decide what that means, but it has to be healthy. It has to be reasonable because otherwise you're just going to be frustrated because like that's how you build software. You make mistakes, you roll it out, you live with it. You see what it feels like and say, oh, God, that was a terrible idea. Oh, my gosh, this could be even better if we did why, right? You turn the crank and then the more you do that, the faster you get ahead of your competitors ultimately, because you're it's rate of change, right? Delta V, right? How fast are you moving? Well, within a year, you're going to be miles away by the time they catch up with you. Right? Like, that's the way it works. And plus users like I, as a software developer, I love software that's constantly changing

• 1:00:58Speaker 01

  because I don't understand people get super pissed off when like, oh, they changed the software on me. How dare they? I'm like, yes, change the software, change it all the time, man. That's, that's what makes this stuff great is that it can be changed so rapidly and become something that that is greater than it is now. Now, granted, there's some changes that suck. Admit, I've seen it many times, but in general, it's like, that's what makes software cool. Right? Is that it is so malleable, like fighting that is like weird to me because it's like, well, you're fighting the essence of the thing that you're building. Like, that doesn't make sense. You want to really embrace that, not, not to be a hummingbird, but like embrace it to a healthy cycle of your heartbeat, right?

• 1:01:33Lex Fridman?

  So you talk about that people really don't change. It's true. The, that's why probably a lot of the stuff you write about in your blog probably will remain true.

• 1:01:43Speaker 01

  There's a flip side of the coin. People don't change. So investing in understanding people is, is like learning Unix in 1970. Because and nothing has changed, right? Like, all those things you've learned about people will still be valid 30, 40 years from now. Whereas if you learn the latest JavaScript framework, that's going to be good for like two years. Right?

• 1:02:00Lex Fridman?

  Exactly. So, but if you look at the future of programming. So there's a people component, but there's also the technology itself. Do you, what do you see as the future of programming? Will it change significantly or as far as you can tell? People are ultimately. Programming and so it will not, it's not something that you foresee changing in any fundamental way.

• 1:02:25Speaker 01

  Well, you gotta go look back on sort of the basics of programming. And one of the things that always shocked me is like source control. Like I didn't learn anything about source control. And granted, I graduated from college in 1992. But I remember hearing from people like as late as like 1998, 1999, like even maybe today, they're not learning source control. And to me, it's like, well, how can you not learn source control? That is so fundamental to working with other programmers, working in a way that you don't lose your work. Like just, just basic software, the bed, literal bedrock of software development is source control. Now you compare it today, like GitHub, right? Like Microsoft bought GitHub, which I think was incredibly smart acquisition move on their part. Now they have, anybody who wants like reasonable source control is go sign up on GitHub. It's all set up for you, right? There's tons of walkthroughs, tons of tutorials.

• 1:03:10Speaker 01

  So from the concept of like, has programming advanced from say 1999? It's like, well, hell, we have GitHub. I mean, my God, yes, right? Like it's massively advanced over, over what it was. Now as to whether programming is significantly different, I'm going to say no. But I think the baseline of like what we view as like fundamentals will continue to go up and actually get better. Like source control, for example, that's one of the fundamentals that has gotten, I mean, hundreds orders of magnitude better than it was 10, 20 years ago.

• 1:03:39Lex Fridman?

  So those are the fundamentals. Let me introduce two things that maybe you can comment on. So one is mobile phones. So that could fundamentally transform what, what programming is, or maybe not. Maybe you can comment on that. And the other one is artificial intelligence, which promises to, in some ways, to do some of the programming for you is one way to think about it. So it's really what a programmer is, is, is using the intelligence that's inside your skull to, to do something useful. The hope with artificial intelligence is that it does some of the useful parts for you where you don't have to think about it.

• 1:04:18Lex Fridman?

  So do you, do you see smartphones, the fact that everybody has one and they're getting more and more powerful as potentially changing programming? And do you see AI as potentially changing programming?

• 1:04:29Speaker 01

  Okay, so that's good. So smartphones have definitely changed. I mean, since, you know, I guess 2010 is when they really started getting super popular. I mean, in the last eight years, the world has literally changed, right? Like everybody carries a computer around and that's normal. I mean, that is such a huge change in society. I think we're still dealing with a lot of the. Positive and negative ramifications of that, right? Like, everybody's connected all the time, everybody's on the computer all the time. That was my dream world as a geek, right? But it's like, be careful what you ask for, right? Like, wow, now everybody has a computer. It's not quite the utopia that we thought it would be, right? Computers can be used for a lot of stuff that's not necessarily great. So to me, that's the central focus of the smartphone is just that it puts a computer in front of everyone. Granted, a small touchscreen, smallish touchscreen computer.

• 1:05:14Speaker 01

  But as for programming, like, I don't know. I don't think that... I've kind of, over time, come to subscribe to the Unix view of the world when it comes to programming. It's like, you want to teach these basic command line things. And that is just what programming is going to be for, I think, a long, long time. I don't think there's any magical, like, visual programming that's going to happen. I just, I don't know. I've, over time, have become a believer in that Unix philosophy of just, you know, they, they kind of had it right with Unix. That's going to be the way it is for a long, long time. And we'll, we'll continue, like I said, raise the baseline. The tools will get better, it'll get simpler, but it's still fundamentally going to be command line tools. You know, fancy IDEs. That's kind of it for the foreseeable future. I'm not seeing any visual programming stuff on the horizon.

• 1:05:57Speaker 01

  Because you kind of think, like, what do you do on a smartphone that will be directly analogous to programming? Like, I'm trying to think, right? Like, and there's really not much.

• 1:06:07Lex Fridman?

  So, not necessarily analogous to programming, but the kind of things that... The kind of programs you would need to write might need to be very different.

• 1:06:22Speaker 01

  Yeah.

• 1:06:23Lex Fridman?

  And the kind of languages, I mean, but I probably also subscribe to the same just because everything in this world might be written in JavaScript.

• 1:06:31Speaker 01

  Oh, yeah, that's definitely, that's already happening. I mean, Discourse is a bet on... Discourse itself, JavaScript, is another bet on that side of the table. And I, I still strongly believe in that. So I would say smartphones have mostly a cultural shift, more than a programming shift. Now, your other question was about artificial intelligence and like... Sort of advice is predicting what you're gonna do. And I do think there's some strength to that. I think artificial intelligence is kind of overselling it in terms of what it's doing. It's more like people are predictable, right? People do the same things. Like, let me give you an example. One one check we put into discourse that's in a lot of big commercial websites is, say you log in from New York City now, and then an hour later, you log in from San Francisco. It's like, well, hmm, that's interesting. How did you get from New York to San Francisco in

• 1:07:14Speaker 01

  one hour? So at that point, you're like, okay, this is a suspicious login at that point. So we would alert you. It's like, okay, but that's not AI, right? That's just heuristic of like, how did you in one hour get 2,000 miles? Right? That doesn't, I mean, you grant, maybe you're on a VPN, there's other ways to happen. But that's just a basic prediction based on the idea that people pretty much don't move around that much. Like, they may travel occasionally, but like, nobody, I mean, unless you're a traveling salesman that's literally, we're traveling the world every day. Like, there's so much repetition and predictability in terms of things you're going to do. And I think good software anticipates your needs. Like, for example, Google, I think it's called Google Now, or whatever that Google thing is, it predicts your commute and predicts based on your phone location, like, where are you every day? Well, that's probably where you work. That kind of stuff. I do think computers can get a lot better

• 1:07:58Speaker 01

  at that. But I hesitate to call it like, full blown AI. It's just computers getting better at, like, first of all, they have a ton of it, because everybody has a smartphone. Now, all of a sudden, we have all this data that we didn't have before about location, about like, you know, communication, and feeding that into some some basic heuristics, and maybe some fancy algorithms that turn it into predictions of anticipating your needs, like, like a friend would, right? Like, oh, hey, I see you're home. Would you like some dinner? Right? Like, let's go get some food, because that's usually what we do this time of day, right?

• 1:08:26Lex Fridman?

  In the context of actually the active programming, do you see IDEs improving and making the life of programming is better?

  I do think that is possible, because there's a lot of repetition in programming, right? Oh, you know, Clippy would be the bad example of, oh, I see, it looks like you're writing a for loop. But there are patterns in code, right? Like, and actually, libraries are kind of like that, right? Like, rather than go, you know, code up your own HTTP request library, it's like, well, you'd use one of the existing ones that we have. It's already troubleshoot, right? It's not AI per se, it's just, you know, Building better Lego bricks, bigger Lego bricks that have more functionality in them. So people don't have to worry about the low level stuff as much anymore. Like WordPress, for example, to me is like a tool for somebody who isn't a programmer to do something. I mean, you can turn WordPress into anything. It's kind of crazy, actually, through plugins, right? And that's not programming per se.

• 1:09:16Speaker 01

  It's just Lego bricks stacking WordPress elements, right? And a little bit of configuration glue. So I would say maybe in a broader sense, what I'm seeing like there'll be more gluing and less like actual programming. And that's a good thing, right? Because most of the stuff you need is kind of out there already.

• 1:09:33Lex Fridman?

  You said 1970s Unix. Do you see PHP and these kind of old

• 1:09:41Lex Fridman?

  remnants of of the early birth of programming remaining with us for a long time? Like you said, Unix in itself. Do you see ultimately, you know, this stuff just being there out of momentum?

• 1:09:58Speaker 01

  I kind of do. I mean, I was a big believer in Windows early on and I was a big, you know, I was like Unix, what a waste of time. But over time, I've completely flipped on that where I was like, okay, the Unix guys were right. And pretty much Microsoft and Windows were kind of wrong, at least on the server side. Now, on the desktop, right, you need a GUI, you need all that stuff. And you have the two philosophies, like Apple built on Unix, effectively Darwin. And on the desktop, it's a slightly different story. But on the server side where you're going to be programming? Now, it's a question of where the programming is going to be. There's going to be a lot more like client side programming because technically Discourse is client side programming. The way you get Discourse, we deliver a big ball of JavaScript, which is then executed locally. So we're really using a lot more local computing power. We'll still retrieve the data. Obviously, we have to display the posts on the screen and so forth.

• 1:10:39Speaker 01

  But in terms of like sorting and a lot of the basic stuff, we're using the host processor. But to the extent that a lot of programming is still going to be server side, I would say, yeah, the Unix philosophy definitely won. And there'll be different veneers over Unix. But it's still, if you peel away one or two layers, it's going to be Unix-y. For a long, I think Unix won, I mean, so definitively.

• 1:11:00Lex Fridman?

  It's interesting to hear you say that because you've done so much excellent work on the Microsoft side in terms of backend development. Cool. So what's the future hold for Jeff Atwood? The discourse, continuing the discourse?

• 1:11:17Lex Fridman?

  In trying to improve conversation on the web.

• 1:11:19Speaker 01

  Well, Discourse is what I view is a, and originally I called it a five-year project, then really quickly revised that to a 10-year project. So we're, we started in early 2013 that we launched the first version. So we're still, you know, five years in. This is the part where it starts getting good. Like, we have a good product now. Discourse, there's any, any project you build in software, it takes three years to build what you wanted to build anyway. Like, V1 is gonna be terrible, which it was, but you ship it anyway, because that's how you get better at stuff. It's about turning the crank. It's not about V1 being perfect, because that's ridiculous. It's about V1, then let's get really good at V1.1, 1.2, 1.3. Like, how fast can we iterate? And I think we're iterating like crazy on Discourse, to the point that like, it's a really good product now. We have serious momentum.

• 1:11:59Speaker 01

  And my original vision was, I want to be the WordPress of discussion, meaning if someone came to you and said, "I want to start a blog," although the very question is kind of archaic now. It's like, who actually blogs anymore? But I wanted the answer to that to be, it would be WordPress normally, because that's the obvious choice for blogging most of the time. But if someone said, "Hey, I want to, I need a group of people to get together and do something," the answer should be Discourse, right? That should be the default answer for people, because it's open source, it's free, doesn't cost you anything, you control it, you can run it. Your minimum server cost for Discourse is five bucks a month at this point. They actually got the VPS prices down. It used to be $10 a month for 1 gigabyte of RAM, which we, we're, our dependent, we have a kind of heavy stack.

• 1:12:43Speaker 01

  Like, there's a lot of stuff in Discourse. You need Postgres, you need Redis, you need Ruby Unrails, you need a sidekick for scheduling. It's not a trivial amount of stuff, because we were architected for like, look, we're building for the next 10 years. I don't care about shared PHP hosting. That's, that's not my model. My idea is like, hey, you know, eventually, this is gonna be very cheap for everybody, and I want to build it right, using, again, you know, higher... Bigger building block levels, right, that have more requirements.

• 1:13:09Lex Fridman?

  And there's a WordPress model of wordpress.org, wordpress.com. Is there a central hosting for Discourse or no?

• 1:13:16Speaker 01

  There is. We're not strictly segmenting into the open source versus the commercial side. We have a hosting business. That's how Discourse makes money is we we host Discourse instances and we have a really close relationship with our customers of the symbiosis of them giving us feedback on the product. We definitely wait feedback from customers a lot heavier than feedback from somebody who just wanders by and gives feedback. But that's where we make all our money, but we don't have a strict division. We encourage people to use Discourse, like the whole point is that it's free, right? You're, anybody can set it up. I don't want to be the only person that hosts Discourse. That's absolutely not the goal, but it is a primary way for us to build a business and it's actually kind of a great business. I mean, the business is going really, really well in terms of hosting.

• 1:13:56Lex Fridman?

  So I, I used to work at Google Research as a company that's basically funded on advertisements. So it's Facebook. Let me ask if you can comment on it. I think advertisement at its best, so you'd be extremely critical on what ads are, but at its best, it's actually serving you in a sense. It's giving you, it's connecting you to what you would want to explore. So it's like related posts or related content. It's the same. That's the best of advertisement. So Discourse is connecting people based on their interests. It seems like a place where advertisement at its best could actually serve the users. Is that something that you're considering, thinking about as a way to bring

• 1:14:42Lex Fridman?

  to financially support the platform?

• 1:14:44Speaker 01

  That's interesting because I actually have a contrarian view of advertising, which I kind of agree with you. I recently installed Ad Blocker like reluctantly because I don't like to do that. But like the performance of the ads, man, like they're so heavy now and like it's just crazy. So like, it's almost like a performance argument more than like, I actually am pro ads and I contrary, I have a contrarian viewpoint. I agree with you. If you do ads right, it's showing you stuff you would be interested in anyway. Like I don't. Mind that that actually is kind of a good thing. So plus, I think it's rational to want to support the people that are doing this work through seeing their ads. And but that said, I run adblock now, which I didn't want to do. But I was convinced by all these articles, like 30, 40 megabytes of stuff, just to serve you ads.

• 1:15:27Lex Fridman?

  Yeah, it feels like ads now are like the experts exchange of whenever you started Stack Overflow is a little bit, it's

• 1:15:34Speaker 01

  Oh, there's so many companies in ad tech that was embarrassing. Like you can do that. Have you seen those logo charts of like, just a whole page? It's like, you can't even see them. They're so small. There's so many companies in the space. But since you brought it up, I do want to point out that very, very few discourse sites actually run using an ad-supported model. It's not effective. Like, it's too diluted. It's too weird. It doesn't pay well. And like, users hate it. So it's a combination of like, users hate it. It doesn't actually work that well in practice. Like, in theory, yes, I agree with you. If you had clean, fast ads that were exactly the stuff you would be interested in, awesome. We're so far from that, though. Right? Like, Google does an okay job. They do retargeting and stuff like that. But in the in the real world, discourse sites rarely can make ads work. It just doesn't

• 1:16:16Speaker 01

  work for so many reasons. But you know what does work is subscriptions, Patreon, affiliate codes for like, Amazon of like, just, oh, here, here's a cool yo-yo, click, and then you click and go to Amazon, and they get a small percentage of that, which is fair, I think. Because you saw the yo-yo on that site, and you click through, and you bought it, right? And that's fair for them to get 5% of that, or 2% of that, or whatever it is. Those things definitely work. In fact, a site that I used to participate on a lot, I helped the owner. One of the things I got them switch to discourse, I basically paid them to switch to discourse, because I was like, look, you guys got to switch. I can't come here anymore on this terrible software. But I was like, look, and on top of that, like, you're serving people ads that they hate. Like, you should just go full on Patreon,

• 1:16:59Speaker 01

  because he had a little bit of Patreon. Go full on Patreon, do the Amazon affiliates thing for any Amazon links that get posted, and just do that, and just triple down on that stuff. And that's worked really well for them, and this creator in particular. So that stuff works. But traditional ads, I mean, definitely not working, at least on discourse.

• 1:17:17Lex Fridman?

  So last question. You've created the code keyboard.

• 1:17:21Lex Fridman?

  I've programmed most of my adult life on a kinesis keyboard. I have one upstairs now. Can you describe what a mechanical keyboard is and why is it something that makes you happy?

• 1:17:32Speaker 01

  Well, you know, this is another fetish item, really, like it's not required. You can do programming on any kind of keyboard, right? Even like an on-screen keyboard. Oh, God, that's terrifying, right? Like, but you could. I mean, if you look back at the early days of computing, there were chiclet keyboards, which are, I mean, those are awful, right? But

• 1:17:46Lex Fridman?

  What's a chiclet keyboard?

• 1:17:47Speaker 01

  Oh, God, OK, well, it's just like thin rubber membranes.

• 1:17:51Lex Fridman?

  Oh, the rubber ones. Oh, no.

• 1:17:53Speaker 01

  Super bad, right?

• 1:17:53Lex Fridman?

  Yeah.

• 1:17:54Speaker 01

  So it's a fetish item. All that really says is, look, I care really about keyboards because the keyboard is the primary method of communication with the computer. Right? So it's just like having a nice mic for this, this podcast. You want a nice keyboard, right? Because it has very tactile feel. I can tell exactly when I press the key. I get that little click. So, oh, and it feels good. And it's also kind of a fetish item. It's like, wow, I care enough about programming that I care about the tool, the primary tool that I use to communicate with the computer. Make sure it's as good as it feels good to use for me. And like, I can be very productive with it. So to be honest, it's a little bit of a fetish item, but a good one. It indicates that you're serious and in case you're interested, it indicates that you care about the fundamentals. Because you know what makes you a good programmer? Being able to type really fast, right? Like, this is true, right?

• 1:18:35Speaker 01

  So a core skill is just being able to type fast enough to get your ideas out of your head into the code base. So just practicing your typing can make you a better programmer.

• 1:18:45Lex Fridman?

  It is also something that makes you, well, makes you enjoy typing, correct? The actual act, something about the process, like I play piano.

• 1:18:56Speaker 01

  It's tactile.

• 1:18:57Lex Fridman?

  There's a tactile feel that ultimately feeds the passion, makes you happy.

• 1:19:02Speaker 01

  Right? No, totally. That's it. I mean, and it's funny because artisanal keyboards have exploded, like Mastrop has gone ballistic with this stuff. There's probably like 500 keyboard projects on Mastrop alone. And there's some other guy I follow on Twitter. I used to write for this, the site, The Tech Report, way back in the day. And he's like, every week he's just posting like what I call keyboard porn of like just cool keyboards. Oh, my God, those look really cool, right? Like, it's like, how many keyboards this guy have? It's kind of like me with yoyos. How many yoyos do you have? How many do you need? Well, technically one, but I like a lot. I don't know why. So same thing with keyboards. So yeah, they're awesome. Like, I highly recommend anybody who doesn't have a mechanical to research it, look into it and see what you like. And, you know, it's ultimately a fetish item, but I think these sort of items, these religious artifacts that we have, are part of what make us human.

• 1:19:47Speaker 01

  Like, that, that part's important, right?

• 1:19:49Lex Fridman?

  It's kind of what makes life worth living.

• 1:19:51Speaker 01

  Yeah. It's not necessary in the strictest sense, but ain't nothing necessary if you think about it, right? Like, so, yeah, why not? So, sure.

• 1:20:00Lex Fridman?

  Jeff, thank you so much for talking today.

• 1:20:02Speaker 01

  Yeah, you're welcome. Thanks for having me.
