397: Dependency Graphs

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
