The Bike Shed

Joël recaps his time at RubyConf! He shares insights from his talk about different aspects of time in software development, emphasizing the interaction with the audience and the importance of post-talk discussions. Stephanie talks about wrapping up a long-term client project, the benefits of change and variety in consulting, and maintaining a balance between project engagement and avoiding burnout. They also discuss strategies for maintaining work-life balance, such as physical separation and device management, particularly in a remote work environment.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: Well, as of this recording, I have just gotten back from spending the week in San Diego for RubyConf. STEPHANIE: Yay, so fun. JOËL: It's always so much fun to connect with the community over there, talk to other people from different companies who work in Ruby, to be inspired by the talks. This year, I was speaking, so I gave a talk on time and how it's not a single thing but multiple different quantities. In particular, I distinguish between a moment in time like a point, a duration and amount of time, and then a time of day, which is time unconnected to a particular day, and how those all connect together in the software that we write. STEPHANIE: Awesome. How did it go? How was it received? JOËL: It was very well received. I got a lot of people come up to me afterwards and make a variety of time puns, which those are so easy to make. I had to hold myself back not to put too many in the talk itself. I think I kept it pretty clean. There were definitely a couple of time puns in the description of the talk, though. STEPHANIE: Yeah, absolutely. You have to keep some in there. But I hear you that you don't want it to become too punny [laughs]. What I really love about conferences, and we've talked a little bit about this before, is the, you know, like, engagement and being able to connect with people. And you give a talk, but then that ends up leading to a lot of, like, discussions about it and related topics afterwards in the hallway or sitting together over a meal. JOËL: I like to, in my talks, give little kind of hooks for people who want to have those conversations in the hallway. You know, sometimes it's intimidating to just go up to a speaker and be like, oh, I want to, like, dig into their talk a little bit. But I don't have anything to say other than just, like, "I liked your talk." So, if there's any sort of side trails I had to cut for the talk, I might give a shout-out to it and say, "Hey, if you want to learn more about this aspect, come talk to me afterwards." So, one thing that I put in this particular talk was like, "Hey, we're looking at these different graphical ways to think about time. These are similar to but not the same as thinking of time as a one-dimensional vector and applying vector math to it, which is a whole other side topic. If you want to nerd out about that, come find me in the hallway afterwards, and I'd love to go deeper on it." And yeah, some people did. STEPHANIE: That's really smart. I like that a lot. You're inviting more conversation about it, which I know, like, you also really enjoy just, like, taking it further or, like, caring about other people's experiences or their thoughts about vector math [laughs]. JOËL: I think it serves two purposes, right? It allows people to connect with me as a speaker. And it also allows me to feel better about pruning...

Stephanie interviews Edward Loveall, a former thoughtbotter, now software developer at Relevant Healthcare. Part of their discussion centers around Edward's blog post on the tech industry's over-reliance on GitHub. He argues for the importance of exploring alternatives to avoid dependency on a single platform and encourages readers to make informed technological choices. The conversation broadens to include how to form opinions on technology, the balance between personal preferences and team decisions, and the importance of empathy and nuance in professional interactions. Both Stephanie and Edward highlight the value of considering various perspectives and tools in software development, advocating for a flexible, open-minded approach to technology and problem-solving in the tech industry.

I'm Stephanie Minn. And today, I'm joined by a very special guest, a friend of the pod and former thoughtboter, Edward Loveall. EDWARD: Hello, thanks for having me. STEPHANIE: Edward, would you share a little bit about yourself and what you're doing these days? EDWARD: Yes, I am a software developer at a company called Relevant Healthcare. We do a lot of things, but the maybe high-level summary is we take very complicated medical data and help federally-funded health centers actually understand that data and help their population's health, which is really fun and really great. STEPHANIE: Awesome. So, Edward, what is new in your world? EDWARD: Let's see, this weekend...I live in a dense city. I live in Cambridge, Massachusetts, and it's pretty dense there. And a lot of houses are very tightly packed. And delivery drivers struggle to find the numbers on the houses sometimes because A, they're old and B, there is many of them. And so, we put up house numbers because I live in, like, a three-story kind of building, but there are two different addresses in the same three stories, which is very weird. And so [laughs], delivery drivers are like, "Where is number 10 or 15?" or whatever. And so, there's two different numbers. And so, we finally put up numbers after living here for, like, four years [chuckles]. So, now, hopefully, delivery drivers in the holiday busy season will be able to find our house [laughs]. STEPHANIE: That's great. Yeah, I have kind of a similar problem where, a lot of the times, delivery folks will think that my house is the big building next door. And the worst is those at the building next door they drop off their packages inside the little, like, entryway that is locked for people who don't live there. And so, I will see my package in the window and, you know, it has my name on it. It has, like, my address on it. And [laughs] some strategies that I've used is leaving a note on the door [laughter] that is, like, "Please redeliver my package over there," and, like, I'll draw an arrow to the direction of my house. Or sometimes I've been that person to just, like, buzz random [laughter] units and just hope that they, like, let me in, and then I'll grab my package. And, you know, if I know the neighbors, I'll, like, try to apologize the next time I see them. But sometimes I'll just be like, I just need to get my package [laughs]. EDWARD: You're writing documentation for those people working out in the streets. STEPHANIE: Yeah. But I'm glad you got that sorted. EDWARD: Yeah. What about you? What's new in your world? STEPHANIE: Well, I wanted to talk a little bit about a thing that you and I have been doing lately that I have been enjoying a lot. First of all, are you familiar with...

Joël got to do some pretty fancy single sign-on work. And when it came time to commit, he documented the ridiculous number of redirects to give people a sense of what was happening. Stephanie has been exploring Rails callbacks and Ruby debugging tools, using methods like save_callbacks and Kernel.caller, and creating a function call graph to better understand and manage complex code dependencies. Stephanie is also engaged in an independent project and seeking strategies to navigate the challenges of solo work. She and Joël explore how to find external support and combat isolation, consider ways to stimulate creativity, and obtain feedback on her work without a direct team. Additionally, they ponder succession planning to ensure project continuity after her involvement ends. They also reflect on the unique benefits of solo work, such as personal growth and flexibility. Stephanie's focus is on balancing the demands of working independently while maintaining a connected and sustainable professional approach.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: I got to do something really fun this week, where I was doing some pretty fancy single sign-on work. And when it came time to commit, I wanted to document the kind of ridiculous number of redirects that happen and give people a sense of what was going on. And for my own self, what I had been doing is, I had done a sequence diagram that sort of shows, like, three different services that are all talking to each other and where they redirect to each other as they all go through the sequence to sign someone in. And I was like, how could I embed that in the commit message? Because I think it would be really useful context for someone trying to get an overview of what this commit is doing. And the answer, for me, was, can I get this sequence diagram in ASCII form somewhere? And I found a website that allows me to do this in ASCII art. It's the textart.io/sequence. And that allows me to create a sequence diagram that gets generated as ASCII art. I can copy-paste that into a commit message. And now anybody else who is like, "What is it that Joël is trying to do here?" can look at that and be like, "Oh, oh okay, so, we got these, like, four different places that are all talking to each other in this order. Now I see what's happening." STEPHANIE: That's super neat. I love the idea of having it directly in your commit message just because, you know, you don't have to go and find a graph elsewhere if you want to understand what's going on. It's right there for you, for future commit explorers [laughs] trying to understand what was going on in this snippet of time. JOËL: I try as much as possible to include those sorts of things directly in the commit message because you never know who's reading the commit. They might not have access to some sort of linked resource. So, if I were like, "Hey, go to our wiki and see this link," like, sure, that would be helpful, but maybe the person reading it doesn't have access to the wiki. Maybe they do have access, but they're not on the internet right now, and so they don't have access to the wiki. Maybe the wiki no longer exists, and that's a dead link. So, as much as possible, I try to embed context directly in my commit messages....

Stephanie discovered a new book: The Staff Engineer's Path! Joël's got some D&D goodness. Together, they revisit a decade-old blog post initially published in 2013, which discussed the application of Sandi Metz's coding guidelines and whether these rules remain relevant and practiced among developers today.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, I picked up a new book from the library [laughs], which that in itself is not very new. That is [laughs] a common occurrence in my world. But it was kind of a fun coincidence that I was just walking around the aisles of what's new in nonfiction, and staring me right in the face was an O'Reilly book, The Staff Engineer's Path. And I think in the past, I've plugged The Manager's Path by Camille Fournier on the show. And in recent years, this one was published, and it's by Tanya Reilly. And it is kind of, like, the other half of a career path for software engineers moving up in seniority at those higher levels. And it has been a really interesting companion to The Manager's Path, which I had read even though I wasn't really sure I wanted to be manager [laughs]. And now I think I get that, like, accompaniment of like, okay, like, instead of walking that path, like, what does a staff plus engineer look like? And kind of learning a little bit more about that because I know it can be really vague or ambiguous or look very different at a lot of different companies. And that has been really helpful for me, kind of looking ahead a bit. I'm not too far into it yet. But I'm looking forward to reading more and bringing back some of those learnings to the show. JOËL: I feel like at the end of the year, Stephanie, you and I are probably going to have to sit down and talk through maybe your reading list for the year and, you know, maybe shout out some favorites. I think your reading list is probably significantly longer than mine. But you're constantly referencing cool books. I think that would probably be a fun, either end-of-year episode or a beginning-of-year episode for 2024. One thing that's really interesting, though, about the contrast of these two particular books you're talking about is how it really lines up with this, like, fork in the road that a lot of us have in our careers as we get more senior. You either move into more of a management role, which can be a pretty significant departure from what you have to do as a developer, or you kind of go into this, like, ultra-senior individual contributor path. But how that looks day to day can be very different from your sort of just traditional sitting down and banging out tickets. So, it's really cool there's two books looking at both of those paths. STEPHANIE: Yeah, absolutely. And I think the mission that they were going for with these books was to kind of illuminate a little bit more about that fork and that decision because, you know, it can be easy for people to maybe just default into one or the other based on what their organization wants for them without, like, fully knowing what that means. And the more senior you get, the more vague and, like, figure it out yourself [laughs] the work becomes. And it can be very daunting to kind of just be thrown into that and be like, well, I'm in this leadership position now....

Joël was selected to speak at RubyConf in San Diego! After spending a month testing out living in Upstate New York, Stephanie is back in Chicago. Stephanie reflects on a recent experience where she had to provide an estimate for a project, even though she didn't have enough information to do so accurately. In this episode, Stephanie and Joël explore the challenges of providing estimates, the importance of acknowledging uncertainty, and the need for clear communication and transparency when dealing with project timelines and scope.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: Big piece of news in my world: I recently got accepted to speak at RubyConf in San Diego next month in November. I'm really excited. I'm going to be talking about the concept of time and how that's actually multiple different things and the types of interactions that do and do not make sense when working with time. STEPHANIE: Yay. That's so exciting. Congratulations. I am very excited about this topic. I'm wondering, is this something that you've been thinking about doing for a while now, or was it just an idea that was sparked recently? JOËL: It's definitely a topic I've been thinking about for a long time. STEPHANIE: Time? [laughs] JOËL: Haha. STEPHANIE: Sorry, that was an easy one [laughs]. JOËL: The idea that we often use the English word time to refer to a bunch of, like, fundamentally different quantities and that, oftentimes, that can sort of blur into one another. So, the idea that a particular point in time might be different from a duration, might be different from a time of day, might be different to various other quantities that we refer to generically as time is something that's been in the back of my mind for quite a while. But I think turning that into a conference talk was a more recent idea. STEPHANIE: Yeah, I'm curious, I guess, like, what was it that made you feel like, oh, like, this would be beneficial for other people? Did everything just come together, and you're like, oh, I finally have figured out time [laughs]; now I have this very clear mental model of it that I want to share with the world? JOËL: I think it was sparked by a conversation I had with another member of the thoughtbot team. And it was just one of those where it's like, hey, I just had this really interesting conversation pulling on this idea that's been in the back of my mind for years. You know, it's conference season, and why not make that into a talk proposal? As often, you know, the best talk proposals are, at least for me, I don't always think ahead of time, oh, this would be a great topic. But then, all of a sudden, it comes up in a conversation with a colleague or a client, or it becomes really relevant in some work that I'm doing. It happens to be conference season, and like, oh, that's something I want to talk about now. STEPHANIE: Yeah, I like that a lot. I was just thinking about something I read recently. It was about creativity and art and how long a piece of work takes. And someone basically said it really just takes your whole life sometimes, right? It's like all of your experiences accumulated together that becomes whatever the body of work is. Like, all of that time spent maybe turning the idea in your head or just kind of, like, sitting with it or having those conversations, all the bugs you've probably encountered [laughs] involving date times, and all of that coalescing into something you want to create. JOËL: And you build this sort of big web of ideas, not all that makes...

Stephanie is engrossed in Kent Beck's Substack newsletter, which she appreciates for its "working thoughts" format. Unlike traditional media that undergo rigorous editing, Kent's content is more of a work-in-progress, focusing on thought processes and evolving ideas. Joël has been putting a lot of thought into various tools and techniques and realized that they all fall under one umbrella term: analysis. From there, Stephanie and Joël discuss all the productivity tricks they like to use in their daily workflows. Do you have some keyboard shortcuts you like? Are you an Alfred wizard?

JOËL: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, I have a new piece of content that I'm consuming lately. That is Kent Beck's Substack [chuckles], Kent Beck of Agile Manifesto and Extreme Programming notoriety. I have been really enjoying this trend of independent content creation in the newsletter format lately, and I subscribe to a lot of newsletters for things outside of work as well. I've been using an RSS feed to like, keep track of all of the dispatches I'm following in that way so that it also kind of keeps out of my inbox. And it's purely just for when I'm in an internet-reading kind of mood. But I subscribed to Kent's Substack. Most of his content is behind a subscription. And I've been really enjoying it because he treats it as a place for a lot of his working thoughts, kind of a space that he uses to explore topics that could be whole books. But he is still in the phase of kind of, like, thinking them through and, like, integrating, you know, different things he's learning, and acknowledging that, like, yeah, like, not all of these ideas are fully fleshed, but they are still worth publishing for people who might be interested in kind of his thought process or where his head is at. And I think that is really cool and very different from just, like, other types of content I consume, where there has been, like, a lot of, especially more traditional media, where there has been, like, more editing involved and a lot of...

Joël describes an old-school object orientation exercise that involves circling nouns in a business problem description. The purpose is determining which nouns could become entities or objects in a system. Stephanie shares she's working from the Hudson Valley in New York as a trial run for potentially relocating there. She enjoys the rail trails for biking and contrasts it with urban biking in Chicago. The conversation between Joël and Stephanie revolves around mentorship, both one-on-one and within a group setting. They introduce a new initiative at thoughbot where team members pair up with principal developers for weekly sessions, emphasizing sharing perspectives and experiences.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: I was recently having a conversation with a colleague about some old-school object orientation exercises that people used to do when trying to do more of the analysis phase of software, ones that I haven't seen come up a lot in the past; you know, 5, 10 years. The particular one that I'm thinking about is an exercise where you write out the sort of business problem, and then you go through and you circle all of the nouns in that paragraph. And then, from there, you have a conversation around which one of these are kind of the same thing and are just synonyms? Which ones might be slight variations on an idea? And which ones should become entities in your system? Because, likely, these things are then going to be objects in the system that you're creating. STEPHANIE: Wow, that sounds really cool. I'm surprised that it's considered old school or, I guess, I haven't heard of it before. So, it's not something in my toolbox these days. But I really like that idea. I guess, you know if you're doing it on pen and paper, it's obviously kind of timeless to me. JOËL: And you could easily do it, you know, in a Google Doc and underline, or highlight, or whatever you want to do. But it's not an exercise that I see people really doing even at the larger scale but even at, the smaller scale, where you have maybe a ticket in your ticketing system, and it has a paragraph there kind of describing what needs to be done. We tend to just kind of jump into, oh, we're going to build a story and do the work and maybe not always think about what are the entities that need to happen out of that. STEPHANIE: I think the other thing that I really like about this idea is the aligning on shared vocabulary. So, if you find yourself using different words for the same idea, is that an opportunity to pick the vocabulary that best represents what this means? Rather than a situation that I often find myself in, where we're all talking about the same things but using different words and sometimes causing a little bit more confusion than I think is necessary. JOËL: Definitely. It can also be a good opportunity to connect with the product or businesspeople around; hey, here are two words that sound like they're probably meaning the same thing. Is there a distinction in your business? And then, you realize, wait a minute, a shopping cart and an order actually do have some slight differences. And now you can go into those. And that probably sparks some really valuable learning about the problem that you're trying to solve that might not come up otherwise, or maybe that only comes up at code review time, or maybe even during the QA phase rather than during the analysis phase. STEPHANIE: Yeah. I think that's really important for us as developers because, as we...

Stephanie has another debugging mystery to share. Earlier this year, Joël mentioned that he was experimenting with a bookmark manager to keep track of helpful and interesting articles. He's happy to report that it's working very well for him! Together, they discuss tactics to ensure the easiest route also upholds app health and aids fellow developers. They explore streamlining test fixes over mere re-runs and how to motivate desired actions across teams and individuals. Raindrop.io (https://raindrop.io/) Railway Oriented Programming (https://fsharpforfunandprofit.com/rop/) Transcript: JOËL: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, I have another debugging mystery to share with the group. I was working on a bug fix and was trying to figure out what went wrong with some plain text that we're rendering from a controller with ERB. And I was looking at the ERB file, and I was like, great, like, I see the method in question that I need to go, you know, figure out why it's not returning what we think it's supposed to return. I went down to go check out that method. I read through it ran the tests. Things were looking all fine and dandy, but I did know that the bug was specific to a particular, I guess, type of the class that the method was being called on, where this type was configured via a column in the database. You know, if it was set to true or not, then that signaled that this was a special thing. You know, I made sure that the test case for that specific type of object was returning what we thought it was supposed to. But strangely, the output in the plain text was different from what our method was returning. And I was really confused for a while because I thought, surely, it must be the method that is the problem here [laughs]. But it turns out, in our controller, we were actually doing a side effect on that particular type of object if it were the case. So, after it was set to an instance variable, we called another method that essentially overwrote all of its associations and really changed the way that you would interact with that method, right? And that was the source of the bug is that we were expecting the associations to return what we, you know, thought it would, but this side effect was very subvertly changing that behavior. JOËL: Would it be fair to call this a classic mutation bug? STEPHANIE: Yeah. I didn't know there was a way to describe that, but that sounds exactly right. It was a classic mutation bug. And I think the assumption that I was making was that the controller code was, hopefully, just pretty straightforward, right? I was thinking, oh, it's just rendering plain text, so not [laughs] much stuff could really be happening in there, and that it must be the method in question that was causing the issues. But, you know, once I had to revisit that assumption and took a look at the controller code, I was like, oh, that is clearly incorrect. And from there, I was able to spot some, you know, suspicious-looking lines that led me to that line that did the mutation and, ultimately, the answer to our mystery. JOËL: Was the mutation happening directly in the controller? Or was this a situation where you're passing this object to a method somewhere, and that method, you know, in another object or some other file is doing the mutation on the record that you passed in? STEPHANIE: Yeah, that's a great question. I think that could have been a very likely situation. But, in this particular case, it was a little more obvious just in the controller code, which was nice, right? Because then I didn't have to go digging into all of these other functions that may or may not be the ones that is doing the mutation. But the thing that was...

Joël shares he has been getting more into long-form reading. Stephanie talks about the challenges she faced in a new project that required integrating with another company's system.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: Something I've been trying to do recently is get more into long-form reading. I read quite a bit of technical content, but most of it are short articles, blog posts, that kind of thing. And I've not read, like, an actual software-related book in a few years, or at least not completed a software-related book. I've started a few chapters in a few. So, something I've been trying to do recently is set aside some time. It's on my calendar. Every week, I've got an hour sit down, read a long-form book, and take notes. STEPHANIE: That's really cool. I actually really enjoy reading technical stuff in a long-form format. In fact, I was similarly kind of trying to do it, you know, once a week, spend a little bit of time in the mornings. And what was really nice about that is, especially if I had, like, a physical copy of the book, I could close my computer and just be completely focused on the content itself. I also love blog posts and articles. We are always talking on the show about, you know, stuff we've read on the internet. But I think there's something very comprehensive, and you can dig really deep and get a very deeper understanding of a topic through a book that kind of has that continuity. JOËL: Right. You can build up a larger idea have more depth. A larger idea can also cover more breadth. A good blog post, typically, is very focused on a single thing, the kind of thing that would really probably only be a single chapter in a book. STEPHANIE: Has your note-taking system differed when you're applying it to something longer than just an article? JOËL: So, what I try to do when I'm reading is I have just one giant note for the whole book. And I'm not trying to capture elements or, like, summarize a chapter necessarily. Instead, I'm trying to capture connections that I make. So, if there's a concept or an argument that reminds me of something perhaps similar in a different domain or a similar argument that I saw made by someone else in a different place, I'll capture notes on that. Or maybe it reminds me of a diagram that I drew the other day or of some work I did on a client six months ago. And so, it's capturing all those connections is what I'm trying to do in my notes. And then, later on, I can kind of go back and synthesize those and say, okay, is there anything interesting here that I might want to pull out as an actual kind of idea note in my larger note-taking system? STEPHANIE: Cool, yeah. I also do a similar thing where I have one big note for the whole book. And when I was doing this, I was even trying to summarize each chapter if I could or at least like jot down some takeaways or some insights or lines that I like felt were...

Stephanie experienced bike camping. Joël describes his experience during a week when he's in between projects. Stephanie and Joël discuss the concept of code ownership, the mechanisms to enforce it, and the balance between bureaucracy and collaboration. They highlight the challenges and benefits of these systems in large codebases and emphasize that scaling a team is as much a social challenge as it is a technical one.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: This weekend, I went bike camping for the first time. So, it was my turn to try out the padded bike shorts and go out on a long ride, combining two things that I really enjoy: biking and camping. It was so awesome. We did about 30 miles outside of the city of Chicago to close to the Indiana border. And we were at a campground that's owned by the forest preserves where I'm at. It was so much fun. I packed all my stuff, including my tent and sleeping bags. And it was something that I never really imagined myself doing, but I'm really glad I did because I think it'll be something that I want to kind of do more of in the future, maybe even do multi-day bike camping trips. JOËL: So, what's your verdict on the bike shorts? STEPHANIE: Definitely a big help. Instead of feeling a little bit sore an hour or so along the bike ride, it kind of helped me stay comfortable quite a bit longer, which was really nice. JOËL: Would you do this kind of trip again? STEPHANIE: I think I would do it again. I think the next step for me is maybe to go even farther, maybe do multiple stops. Yeah, I was talking to my partner about it who came along with me, and he was saying, like, "Yeah, now that you've done that many miles in one day and, you know, camped overnight, you can really go anywhere. [laughs] You can go as far as you want." And I thought that was pretty cool because, yeah, he's kind of right, where I can just pack up and go and, you know, who knows where I'll end up? Not that I would actually do that because of my need to plan. [laughs] I'm not that go-with-the-flow. But there was definitely something really special about being able to get from A to B with just, like, my physical body and not relying on any other kind of transportation. JOËL: Yeah, there's a certain freedom to that spontaneity that's really nice. STEPHANIE: Yeah. And I actually went with a group called Out Our Front Door. And if anyone is in Chicago and is interested in doing this kind of thing, they do group bike camping adventures, and they make it really accessible. So, it's a very easy pace. You are with a group, so it's just really fun. They make it really safe. And I had a really great time. There was about 60 of us actually at camp, and they had rented out the entire campground, so it was just our group. And they even had a live reggae band come out and play music for us while we had dinner. And that was a really nice way for me to do it as a first-timer because there was stuff already planned for me, like meals. And I didn't have to worry about that because I was already, you know, just worrying about making sure I got there with all of my stuff. So, if that sounds interesting to you and you're in Chicagoland, definitely check them out. JOËL: That's a great way to bring in newer people to say, let's have a semi-organized thing, where all you have to focus on is the skill itself, you know, can I bike the 30 miles? Rather than planning all the logistics around it. STEPHANIE: Yeah, exactly. Joël, what's new in your world? JOËL: So, speaking of planning and logistics, this week, I'm in between projects at...

Want a cool cucumber salad? Joël's got you covered. Stephanie has evolved and found some pickles she enjoys. Experienced programmers use a lot of heuristics or "rules of thumb" about what makes their code better. These aren't always true, but they work in most situations. Stephanie and Joël discuss a range of heuristics, how to use them, how to come up with them, how to know when to break them, and how to teach them to more junior devs. Pickled mustard seeds (https://www.youtube.com/watch?v=aLMFGk7Ylw0) The purpose of a system is what it does (https://en.wikipedia.org/wiki/The_purpose_of_a_system_is_what_it_does) Intro to empirical software engineering by Hillel Wayne (https://www.youtube.com/watch?v=WELBnE33dpY) Transcript: STEPHANIE: Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: So, as of the recording of this, summer is in full swing, and it's the time of year where we have all these, you know, fresh vegetables out, so I've been really enjoying a lot of those. I think this week; in particular, I've been going into, like, all the variations on cucumber salads. STEPHANIE: Ooh. JOËL: Yeah. So, that's been kind of fun for me. A fun thing I've been doing to spice this up is pickling mustard seeds to add as a topping. That's actually really amazing. It adds just a little bit of acidity, a little bit of crunch, a little bit of texture. And it's pretty. STEPHANIE: That sounds so delicious. And also, I was going to share something about pickles about what's new in my world. [laughs] But first, I am curious, what has been your go-to cucumber salad that you put this pickled mustard seed situation on top? JOËL: So, cucumbers and tomatoes is just the base of everything. And then, it kind of goes with random things I have in my fridge. A little bit of goat cheese on top can be a great topping, big fan of balsamic glaze. You can just get, like, a bottle of that at the grocery store, the pickled mustard seeds. I've recently been trying topping with a fried egg. STEPHANIE: Ooh, that sounds really fun. It kind of, like, adds a bit of savoriness and creaminess and maybe even, like, the crunchy fried edges. That sounds really yummy. JOËL: Particularly if you do it over easy where the center is not fully cooked. When the egg breaks, you effectively get salad dressing for free. STEPHANIE: That sounds so delicious. JOËL: Summer vegetables, they're great. STEPHANIE: They are great. Last year, I did have a cucumber garden, as in a garden, and a few cucumber plants that were too prolific for me, to be honest. I found myself overrun with cucumbers and having to give them away because we just didn't eat them enough. And this year, we scaled back a little bit [laughs] on the cucs. But I am so excited to bring up what's new in my world now because it's, like, so related, and we did not plan this at all. But I have a silly little thing to share about my own pickle journey. So, I used to be a pickle hater. JOËL: You know what? Same. STEPHANIE: Oh my gosh, incredible. Another new thing we've learned about each other. I really, like, wanted to like pickles because, you know, when you order a sandwich in a restaurant, it always comes with the pickle spear. And neither me nor my partner were into pickles, and we would always leave the spear uneaten on the plate, and we felt so bad about it. I felt really bad about it. And so, every, like, three to six months or so, I'd be like, okay, I'm going to gather the courage to try the pickle again and see if maybe my taste buds have changed, and this time I'll like it. And, you know, I would try a bite and just be like, no, no, I don't think it's for me. [laughs] But I guess I was just so primed to do something about, like, wanting to eliminate this...

Stephanie is consciously trying to make meetings better for herself by limiting distractions. A few episodes ago, Joël talked about a frustrating bug he was chasing down and couldn't get closure on, so he had to move on. This week, that bug popped up again and he chased it down! AND he got to use binary search to find its source–which was pretty cool! Together, Stephanie and Joël discuss dependency graphs as a mental model, and while they apply to code, they also help when it comes to planning tasks and systems. They talk about coupling, cycles, re-structuring, and visualizations.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, I'm always trying to make meetings better for me [chuckles], more tolerable or more enjoyable. And in meetings a lot, I find myself getting distracted when I don't necessarily want to be. You know, oftentimes, I really do want to try to pay attention to just what I'm doing in that meeting in the moment. In fact, just now, I was thinking about the little tidbit I had shared on a previous episode about priorities, where really, you know, you can only have one priority [laughs] at a time. And so, in that moment, hopefully, my priority is the meeting that I'm in. But, you know, I find myself, like, accidentally opening Slack or, like, oh, was I running the test suite just a few minutes before the meeting started? Let me just go check on that really quick. And, oh no, there's a failure, oh God, that red is really, you know, drawing my eye. And, like, could I just debug it really quick and get that satisfying green so then I can pay attention to the meeting? And so on and so forth. I'm sure I'm not alone in this [laughs]. And I end up not giving the meeting my full attention, even though I want to be, even though I should be. So, one thing that I started doing about a year ago is origami. [laughs] And that ended up being a thing that I would do with my hands during meetings so that I wasn't using my mouse, using my keyboard, and just, like, looking at other stuff in the remote meeting world that I live in. So, I started with paper stars, made many, many paper stars, [laughs] and then, I graduated to paper cranes. [laughs] And so, that's been my origami craft of choice lately. Then now, I have little cranes everywhere around the house. I've kind of created a little paper crane army. [laughs] And my partner has enjoyed putting them in random places around the house for me [laughs] to find. So, maybe I'll open a cabinet, and suddenly, [laughs] a paper crane is just there. And I think I realized that I've actually gotten quite good at doing these crafts. And it's been interesting to kind of be putting in the hours of doing this craft but also not be investing time, like, outside of meetings. And I'm finding that I'm getting better at this thing, so that seemed pretty cool. And it is mindless enough that I'm mentally just paying attention but, yeah, like, building that muscle memory to perfecting the craft of origami. JOËL: I'm curious, for your army of paper cranes, is there a standard size that you make, or do you have, like, a variety of sizes? STEPHANIE: I have this huge stack of, like, 500 sheets of origami paper that are all the same size. So, they're all about, let's say, two or three inches large. But I think the tiny ones I've seen, really small paper cranes, maybe that would be,...

Joël has been fighting a frustrating bug where he's integrating with a third-party database, and some queries just crash. Stephanie shares her own debugging story about a leaky stub that caused flaky tests. Additionally, they discuss the build vs. buy decision when integrating with third-party systems. They consider the time and cost implications of building their own integration versus using off-the-shelf components and conclude that the decision often depends on the specific needs and priorities of the project, including how quickly a solution is needed and whether the integration is core to the business's value proposition.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: My world has been kind of frustrating recently. I've been fighting a really frustrating bug where I'm integrating with a third-party database. And there are queries that just straight-up crash. Any query that instantiates an instance of an ActiveRecord object will just straight-up fail. And that's because before, we make the actual query, almost like a preflight query that fetches the schema of the database, particularly the list of tables that the database has, and there's something in this schema that the code doesn't like, and everything just crashes. Specifically, I'm using an ODBC connection. I forget exactly what the acronym stands for, Open Database connection, maybe? Which is a standard put up by Microsoft. The way I'm integrating it via Ruby is there's a gem that's a C extension. And somewhere deep in the C extension, this whole thing is crashing. So, I've had to sort of dust off some C a little bit to look through. And it's not super clear exactly why things are crashing. So, I've spent several days trying to figure out what's going on there. And it's been really cryptic. STEPHANIE: Yeah, that does sound frustrating. And it seems like maybe you are a little bit out of your depth in terms of your usual tools for figuring out a bug are not so helpful here. JOËL: Yeah, yeah. It's a lot harder to just go through and put in a print or a debug statement because now I have to recompile some C. And, you know, you can mess around with some things by passing different flags. But it is a lot more difficult than just doing, like, a bundle open and binding to RB in the code. My ultimate solution was asking for help. So, I got another thoughtboter to help me, and we paired on it. We got to a solution that worked. And then, right before I went to deploy this change, because this was breaking on the staging website, I refreshed the website just to make sure that everything was breaking before I pushed the fix to see that everything is working. This is a habit I've picked up from test-driven development. You always want to see your test break before you see it succeed. And this is a situation where this habit paid off because the website was just working. My changes were not deployed. It just started working again. Now it's gotten me just completely questioning whether my solution fixes anything. The difficulty is because I am integrating [inaudible 03:20] third-party database; it's non-deterministic. The schema on there is changing rather frequently. I think the reason things are crashing is because there's some kind of bad data or data that the ODBC adapter doesn't like in this third-party system. But it just got introduced one day; everything started breaking, and then somehow it got removed, and everything is...

Stephanie had a small consulting win: saying no to a client. GeoGuessr is all the rage for thoughtbot's remote working culture, which leads to today's topic of forming human connections in a virtual (work) environment.

[laughter] Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, I have a small consulting win, or even just a small, like, win as a human being [laughs] that I want to share, which is that I feel good about a way that I handled saying no to a stakeholder recently. And, you know, I really got to take them where I can get it because that is so challenging for me. But I feel really glad because we ended up kind of coming out the other side of it having a better understanding of each other's goals and needs. And so, basically, what happened was I was working on a task, and our product owner on our team asked me if it could be done by next week. And immediately, I wanted to say, "Absolutely not." [laughs] But, you know, I took a second and, you know, I had the wherewithal to ask why. You know, I was kind of curious, like, where was this deadline coming from? Like, what was on her radar that, like, wasn't on mine? And she had shared that, oh, you know, if we were able to get it out before this big launch, she was thinking that it actually might make our customer support team's lives easier because we were kind of taking away access to something before some new features rolled out. And, you know, there might be some customers who would complain. And with that information, you know, that was really helpful in helping me understand. And I'm like, yeah, like, that seems like a helpful thing to know, so I could try to strive for it. Because I also, like, want to make that process go easier as well. But I told her that I'd let her know because I honestly wasn't sure if it was possible to do by next week. And after a little bit of, you know, more digging, kind of seeing how my progress was going, in the end, I had to say that I didn't feel confident that we could finish it in time for that deadline because of the other risks, right? Like, I didn't want to just release this thing without feeling good about the plan that we had. And so, that was my small, little win in saying no, and I feel very proud of myself for it. JOËL: I'm proud of you too. That's not easy to just do in the first place, and then to do it well is a whole other level. It sounds, though, that you came out of the other side with the client with almost, like, a better relationship. STEPHANIE: Yeah, I think so. In general, you know, I really struggle when people do end up getting into that debate of, like, "Well, I need this." And someone else says, "Well, I need this other thing." And, you know, at some point, it kind of gets a bit unproductive, right? But I think this was a very helpful way for me to see a path forward when maybe we, like, have different priorities. But, like, can we better understand each other and the impact of them to ultimately, like, make the best decision? The other thing that I wanted to share that I learned recently was there was a recent RailsConf talk by Elle Meredith, and it was about strategies to say no, and I watched it. And one really cool thing that I learned was that the word priority, you know, when it was first created, it actually didn't really have, like, a plural form. There was really...

Joël recently had a fascinating conversation with some friends about the power of celebrating and highlighting small wins in their lives. He talks about bringing this into his work life.

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we've come here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: I've been having a really interesting conversation with some of my friends recently about the power of celebrating and highlighting small wins in our lives, both in, like, kind of sharing it with each other, like, you know, if something small happens, it's good for me to share it with my friends. But also, where it becomes really cool is where the friend group kind of gets together and celebrates that small win for one person, and how that can be, like, a small step to take, but it's just really powerful and encouraging for a friend group. And I think that applies not just among friends but in a team or other grouping in the workplace. STEPHANIE: That's so fun. How are you celebrating these small wins, like, over text? Is that the main way you're communicating something good that happened? JOËL: It depends on the friend group. I think, like, different friend groups will have, like, a different kind of cadence for the kind of things they do. And do they all hang out together? Do they have a group text, things like that? One of the friend groups I'm a part of, we meet weekly to go climbing at a rock-climbing gym, so that's kind of our hang-out. And [inaudible 01:34], we're there to do stuff at the gym, but it's also a social thing. And it's an opportunity to be like, "Oh, you know, did that thing workout, you know, at work?" "You know, good for you," Or "Did you get this project accepted?" And yeah, when small wins come up, it's a great time to celebrate. STEPHANIE: That's awesome. I think having regular time that you see people and being able to ask them about something that they had mentioned previously is so special and really important to me, like, in bonding and building the relationship. I also love the idea of celebrating milestones. So, this is, I guess, more of a bigger win, but milestones that aren't traditionally celebrated. You know, so, yeah, we'll have, like, a party when someone graduates or someone gets married. But I also have really enjoyed celebrating when someone gets a promotion at work. And, you know, maybe that's not, like, a once-in-a-lifetime thing, but it's still so worthy of going out for dinner or buying them a drink. I also will maybe, like, send my friends a little treat if I know that they did something small but hard for them, right? And sometimes that's even, like, responding to a scary email that they had sitting in their inbox for a while. Yeah, I really love that idea of supporting people, even in the small things in life that they do. JOËL: Yeah, and that's really validating, I think when you've done something hard and then a friend or a colleague reaches out to you. And it's kind of like, hey, I saw that. Good for you. STEPHANIE: How have you been thinking about bringing this into your work life? JOËL: I think it's about being on the lookout for things that other people do. And I think one thing I like to do is kind of publicly calling that out. It sounds like a negative thing, right?...

It's updates on the work front today! Stephanie was tasked with removing a six-year-old feature flag from a codebase. Joël's been doing a lot of small database migrations. A listener question sparked today's main discussion on gerunds' interesting relationship to data modeling.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: So, this week, I've been tasked with something that I've been finding very fun, which is removing a six-year-old feature flag from the codebase that is still very much in use in the sense that it is actually a mechanism for providing customers access to a feature that had been originally launched as a beta. And that was why the feature flag was introduced. But in the years since, you know, the business has shifted to a model where you have to pay for those features. And some customers are still hanging on to this beta feature flag that lets them get the features for free. So one of the ways that we're trying to convert those people to be paying for the feature is to, you know, gradually remove the feature flag and maybe, you know, give them a heads up that this is happening. I'm also getting to improve the codebase with this change as well because it has really been propagating [laughs] in there. There wasn't necessarily a single, I guess, entry point for determining whether customers should get access to this feature through the flag or not. So it ended up being repeated in a bunch of different places because the feature set has grown. And so, now we have to do this check for the flag in several places, like, different pages of the application. And it's been really interesting to see just how this kind of stuff can grow and mutate over several years. JOËL: So, if I understand correctly, there's kind of two overlapping conditions now around this feature. So you have access to it if you've either paid for the feature or if you were a beta tester. STEPHANIE: Yeah, exactly. And the interesting thought that I had about this was it actually sounds a lot like the strangler fig pattern, which we've talked about before, where we've now introduced the new source of data that we want to be using moving forward. But we still have this, you know, old limb or branch hanging on that hasn't quite been removed or pruned off [chuckles] yet. So that's what I'm doing now. And it's nice in the sense that I can trust that we are already sending the correct data that we want to be consuming, and it's just the cleanup part. So, in some ways, we had been in that half-step for several years, and they're now getting to the point where we can finally remove it. JOËL: I think in kind of true strangler fig pattern, you would probably move all of your users off of that feature flag so that the people that have it active are zero, at which point it is effectively dead code, and then you can remove it. STEPHANIE: Yeah, that's a great point. And we had considered doing that first, but the thing that we had kind of come away with was that removing all of those customers from that feature flag would probably require a script or, you know, updating the production data. And that seemed a bit riskier actually to us because it wasn't as reversible as a code change. JOËL: I think you bring up a...

Joël has a fascinating discovery! He learned a new nuance around working with dependency graphs. Stephanie just finished playing a 100-hour video game on Nintendo Switch: a Japanese role-playing game called Octopath Traveler II. On the work front, she is struggling with a lot of churn in acceptance criteria and ideas about how features should work. How do these get documented? What happens when they change? What happens when people lose this context over time?

STEPHANIE: Oh, I am. Okay, great. Hello and welcome to another episode of The Bike Shed, a weekly podcast from your friends at thoughtbot about developing great software. I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: So long-time Bike Shed listeners will know that I'm a huge fan of dependency graphs for modeling all sorts of problems and particularly when trying to figure out how to work in an iterative fashion where you can do a bunch of small chunks of work that are independent, that can be shipped one at a time without having your software be in a breaking state in all of these intermediate steps. And I recently made a really exciting discovery, or I learned a new nuance around working with dependency graphs. So the idea is that if you have a series of entities that have dependencies on each other, so maybe you're trying to build, let's say, some kind of object model or maybe a series of database tables that will reference each other, that kind of thing, if you draw a dependency graph where each bubble on your graph points to other bubbles that it depends on, that means that it can't be created without those other things already existing. Then, in order to create all of those entities for the first time, let's say they're database tables, you need to work your way from kind of the outside in. You start with any bubbles on your graph that have no arrows going out from them. That means they have no dependencies. They can be safely built on their own, and then you kind of work your way backwards up the arrows. And that's how I've sort of thought about working with dependency graphs for a long time. Recently, I've been doing some work that involves deleting entities in such a graph. So, again, let's say we're talking about database tables. What I came to realize is that deleting works in the opposite order. So, if you have a table that have other tables that depend on it, but it doesn't depend on anything, that's the first one you want to create. But it's also the last one you want to delete. So, when you're deleting, you want to start with the table that maybe has dependencies on other tables, but no other tables depend on it. It is going to be kind of like the root node of your dependency graph. So I guess the short guideline here is when you're creating, work from the bottom up or work from the leaves inward, and when you're deleting, work from the top-down or work from the root outward or roots because a graph can have multiple roots; it's not a tree. STEPHANIE: That is interesting. I'm wondering, did you have a mental model for managing deleting of dependencies prior? JOËL: No. I've always worked with creating new things. And I went into this task thinking that deleting would be just like creating and then was like, wait a minute, that doesn't work. And then, you know, a few cycles later, realized, oh, wait, deleting is the opposite of creating when you're navigating the graph. And, all of a sudden, I feel like I've got a much clearer mental model or just another way of thinking about how to work with something like this. STEPHANIE: Cool....

Stephanie went to her first WNBA game. Also: Bingo. Joël's new project has him trying to bring in multiple databases to back their ActiveRecord models. He's never done multi-database setups in Rails before, and he doesn't hate it. Stephanie shares bits from a discussion with former Bike Shed host Steph Viccari about learning goals. Four elements stood out: Adventure (try something new) Passion (topic) Profit (from recent learnings) Low-risk (applicable today) = APPL Stephanie and Joël discuss what motivates them, what they find interesting vs. what has immediate business value, and how they advocate for themselves in these situations. They ponder if these topics can bring long-term value and discuss the impact that learning Elm had on Joël's client work.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: All right, I have a new-new thing and an old-new thing to share with you today. So the new-new thing is that I went to my first WNBA game [laughs] last week, which is also my third professional sports game ever, probably. I am not a sports person. But a rather new friend of mine invited me to go with her because they are fans, and so I was like, yeah, sure. I'll try anything once. And I went, and I had a great time. It was very exciting. I mean, I know the basic rules of basketball, right? Get the ball in the hoop. But I was very surprised to see how fast-paced it was. And, you know, I was like, wow, like, this is so much fun. There's so much going on, like, the music, you know, the crowd. It was very energizing. And then my friend actually told me that that was a pretty slow game, [chuckles] relative to how they normally go. And I was like, oh, wow, like, if that was slow, then I can't wait for a real competitive [laughs] game next time. So that's my new-new thing. I had a good time. Will do it again. I'm just, like, a 15-minute bike ride from the stadium for our team in Chicago. It's called The Sky. That's our WNBA team. So yeah, I'm looking forward to being basketball Stephanie, I guess. [chuckles] JOËL: That's really cool. How does the speed compare to other sports you've gone to see? STEPHANIE: I think this is why I was interested because I've really only seen baseball, for which I know very little. And that, I think, is, like, a much slower-paced kind of sport. Yeah, I have some memories of going to, like, college football games, which also, like, quite slow. I just remember standing around for a while. [laughs] So I think basketball might be the thing for me, at least in terms of engaging my interest. JOËL: You want something that actually engages you with the sport the whole time. It's not just a social event themed around occasionally watching someone do something. STEPHANIE: Yes, exactly. I also enjoyed the half-time performances, you know, there was just, like, a local dance team. And I thought that was all just very fun. And, yes, I had a lot to, you know, just, like, point to and ask questions about because there was just so much going on, as opposed to sitting and waiting, at least that was my experience [laughs] at other kinds of sports games. As for the old-new thing, now that it's summer, there is a local bar near me that does bingo every week. But it's not just normal bingo. It's called veggie bingo, which I realize is kind of confusing [chuckles] if you just, like, call it veggie bingo, but it's bingo...

Joël's new work project involves tricky date formats. Stephanie has been working with former Bike Shed host Steph Viccari and loved her peer review feedback. The concept of truthiness is tough to grasp sometimes, and JavaScript and Ruby differ in their implementation of truthiness. Is this a problem? Do you prefer one model over the other? What can we learn about these design decisions? How can we avoid common pitfalls?

I'm Stephanie Minn. JOËL: And I'm Joël Quenneville. And together, we're here to share a little bit of what we've learned along the way. STEPHANIE: So, Joël, what's new in your world? JOËL: So I'm on a new project at work. And I'm doing some really interesting work where I'm connecting to a remote database third-party system directly and pulling data from that database into our system, so not via some kind of API. And one thing that's been really kind of tricky to work with are the date formats on this third-party database. STEPHANIE: Is the date being stored in an unexpected format or something like that? JOËL: Yes. So there's a few things that are weird with it. So this is a value that represents a point in time, and it's not stored as a date-time value. Instead, it's stored separately as a date column and a time column. So a little bit of weirdness there. We can work with it, except that the time column isn't actually a time value. It is an integer. STEPHANIE: Oh no. JOËL: Yeah. And if you're thinking, oh, okay, an integer, it's going to be milliseconds since midnight or something like that, which is basically how Postgres' time of day works under the hood, nope, that's not how it works. It's a positional digit thing. So, if you've got the number, you know, 1040, that means 10:40 a.m. STEPHANIE: Oh my gosh. Is this in military time or something like that, at least? JOËL: Yes, it is military time. But it does allow for all these, like, weird invalid values to creep in. Because, in theory, you should never go beyond 2359. But even within the hours that are allowed, let's say, between 1000 and 1100, so between 10:00 and 11:00 a.m., a clock only goes up to 59 minutes. But our base 10 number system goes up to 99, so it's possible to have 1099, which is just an invalid time. STEPHANIE: Right. And I imagine this isn't validated or anything like that. So it is possible to store some impossible time value in this database. JOËL: I don't know for sure if the data is validated or not, but I'm not going to trust that it is. So I have to validate it on my end. STEPHANIE: That's fair. One thing that is striking me is what time is zero? JOËL: So zero in military time or just 24-hour clocks in general is midnight. So 0000, 4 zeros, is midnight. What gets interesting, though, is that because it's an integer, if you put the number, you know, 0001 into the database, it's just going to store it as 1. So I can't even say, oh, the first two digits are the hours, and the second two digits are the minutes. And I'm actually dealing with, I think, seconds and then some fractional part of seconds afterwards. But I can't say that because the number of digits I have is going to be inconsistent. So, first, I need to zero pad. Well, I have to, like, turn it into a string, zero pad the numbers so it's...

Stephanie just got back from a smaller regional Ruby Conference, Blue Ridge Ruby, in Asheville, North Carolina. Joël started a new project at work. Review season is upon us. Stephanie and Joël think about growth and goals and talk about reviews: how to do them, how to write them for yourself, and how to write them for others.

I'm Joël Quenneville. STEPHANIE: And I'm Stephanie Minn. And, together, we're here to share a bit of what we've learned along the way. JOËL: So, Stephanie, what's new in your world? STEPHANIE: I just came back from a smaller regional Ruby Conference, Blue Ridge Ruby, in Asheville, North Carolina. And I had a really great time. JOËL: Oooh, I'll bet this is a great time of year to be in Asheville. It's The Blue Ridge Mountains, right? STEPHANIE: Yeah, exactly. It was perfect weather. It was in the 70s. And yeah, it was just so beautiful there, being surrounded by mountains. And I got to meet a lot of new and old Ruby friends. That was really fun, seeing some just conference folks that I don't normally get to see otherwise. And, yeah, this was my second regional conference, and I think I am really enjoying them. I'm considering prioritizing going to more regional conferences over the ones in some of the bigger cities that Ruby Central puts on moving forward. Just because I really like visiting smaller cities in the U.S., places that I otherwise wouldn't have as strong of a reason to go to. JOËL: And you weren't just attending this conference; you were speaking. STEPHANIE: I was, yeah. I gave a talk that I had given before about pair programming and nonviolent communication. And this was my first time giving a talk a second time, which was interesting. Is that something that you've done before? JOËL: I have not, no. I've created, like, a new bespoke talk for every conference that I've been at, and that's a lot of work. So I love the idea of giving a talk you've given before somewhere else. It seems like, you know, anybody can watch it on the first time on YouTube, generally. But it's not the same as being in the room and getting a chance for someone to see you live and to give a talk, especially at something like a regional conference. It sounds like a great opportunity. What was your experience giving a talk for the second time? STEPHANIE: Well, I was very excited not to do any more work [chuckles] and thinking that I could just show up [chuckles] and be totally prepared because I'd already done this thing before. And that was not necessarily the case. I still kind of came back to my talk after a few months of not looking at it for a while and had some fresh eyes, rewrote some of the things. I was able to apply a few things that I had learned since giving it the first time around, which was good, just having more perspective and insight into the things that I was talking about. Otherwise, the content didn't really change, just polished it further. I think in the editing process, you could edit forever, really. So I imagine if I revisit it again, I'll find other things that I want to change. But this time around, I also memorized my slides because, last time, I was a little more dependent on my speaker notes. And part of what I wanted to do this time around, because I had a little more time in preparing, was trying to...
