Likes How Big Things Get Done. Recommends The Undoing Project.

“Outlive by Peter Attia is fantastic. Another one that's I guess maybe related, I hurt my back so it's not great, Back Mechanic by Stuart McGill is incredible. Shout out to anyone who has hurt lower back. It's for a lay person to read through and figure out how to fix lower back problems. It's kind of a random one. I will say I love How Big Things Get Done. I can't pronounce the names. I think one's... There's Scandinavian, one is. It kind of dissects really large projects through recent-ish history and where they failed and why. And I think it's really interesting for us to think about, especially now in this AI moment where basically all of our at least software systems are going to be changing. So how do we think about approaching what is essentially going to be a very large project? And then, sorry, I'm going to throw in a bonus one, The Undoing Project by Michael Lewis. Matt Velloso recommended it to me, and it's so good.”

There's the common ones, Copilot, Cursor. I don't know. Is there anything that stands out that you want to share, just like, "Hey, you should check this tool out.

Within DevEx is productivity, and I think the key insight that you had and other folks in the space of that is not just productivity, but there's also engineering happiness.

I had a Calabrian. That was the best. Happy devs make happy code. They write better programs, they do better work, they're better team members and collaborators.

It helps us with market share, it helps us attract and retain customers, it helps us do all of these things. And I think DevEx is important because it enables all of that software creation, it enables all of that problem solving.

DevEx is developer experience. And when we think about developer experience, we're really talking about what it's like to build software, day to day, for a developer.

We're still figuring out what the best flow state and cognitive requirements are for people in this because, to your point, sometimes we're getting interrupted all the time.

Now that our attention has to focus on things at certain times and it's broken up from how we used to do it, I think there's some real opportunity there to, not just rethink workflows, but rethink how we structure our days and how we structure our work.

Because it feels like it's just another internal project that isn't going to matter or that isn't going to get celebrated, but it has these huge upside potential returns for the business.

Because implied in that is feedback loops, right, because you used to kind of get feedback from customers. But we can't just use that blindly now when we're using AI, as an example, because we have feedback loops much earlier and not even just at the local build and test phase.

I think there are a lot of ways that we can pull in AI tools to help us refine our strategy, refine our message, think about the experimentation methods or targets of experimentation, or think about our total addressable market, but we need to have that strategy and plan fairly well aligned or at least have two or three alternatives that you want to test.
