Another good reason to begin documenting your Theory of The Program: it’s a way to combat the death of the author. If you have explicitly written down the intentions of some software, and what it assumed, then others cannot add assumptions onto you in the future. You are also forced into honesty about what you initially considered and how you perceived the world. (From reading ferd.ca’s thoughts on language and inclusiveness)

I would really love to see programmers/maintainers of influential libraries, frameworks, and languages (Redux, SwiftUI, Erlang, etc.) begin to describe their Theory Building as top-level documentation in the source code.
I think several maintainers do good work to educate everyone with conference talks and blog posts (Rich Hickey, Dan Abramov, etc.), but documentation with the project would be amazing as an introduction with the codebase.

It is not enough to simply architect a system or solution. You must create a story, a path through it, from your current state to multiple end states. If you simply present a picture of end state, members do not know what to do to contribute. The path and the narrative is the actual useful solution. Architecture or solution alone is an empty vessel.
You can know what you are to do only if you also know what story you are a part of.

Often, people who don’t have access to the raw data expect one narrative to be drawn from data analysis. But the analysts actually in the data know that there are always many, many narratives in the data. Data is opposite a single narrative.
The narratives coming from the data are also never closed or complete, as data continuously arrives. But people want and attach themselves to a single narrative.

Listening to win vs. listening to fix vs. listening to learn. The default position for engineers and executives is listening to fix. You’re employed to move things forward and solve problems. Sales’ default position is listening to win - to convert the sale, listening to sell. But good product work requires listening to learn. You can fix it later, iteratively, but first you need to soak it in with no idea on how to fix it. (While listening to Jennifer Garvey Berger.)

Code performance, reliability, security, cleanliness. These things are not achieved through big sweeps and special efforts. They are only really possible by baking the practices into every day and each decision. You can’t focus on fixing them for a week. You need to invest in them slowly, constantly, over the life of the project. (Thoughts after reading about why NetNewsWire is fast, listening to a code audit webinar, and thinking about how we’ve done so much with 2 engineers at OfficeLuv.)

Identifying too many aspects of ongoing product work as tech debt has caused engineering teams to over-invest too early. They fear the tech debt in the future if they don’t make the decision now that’s perfect for that orders-of-magnitude-bigger future. They think tech debt can be avoided with more tech investment, but I don’t think it works that way. You want to invest slowly and constantly, just like the stock market.
So many people think they can time the stock market right and buy the dip - engineers think the same way and try to predict where they should invest heavily up front. Instead, invest where you know you need it and then expand that investment as you expand the product.

The actual nerdy economics joke there is in the second paragraph, which takes the form: Two economists are walking down the street. One of them sees a $20 bill on the ground. As she bends to pick it up, her colleague says “don’t bother, if that was a real $20 bill someone would have picked it up by now.” She replies, “no see this was left here by a consumer tech startup trying to maximize user growth; their Monthly Active Picker-Upper numbers are doubling every two months.” She picks up the $20 bill and the startup raises money at a $2 billion valuation.

In product research, people sometimes make the mistake of ‘validating’ their product idea by interviewing customers and describing the most generic version of their product. The customer already has a problem, so a product generic enough to solve all their problems sounds wonderful and they want that. But once you get down to building specifics and you haven’t solved all the problems right away, they won’t switch away from the incumbent solution because it doesn’t solve one of their problems better.
Software engineers are a similar way, in that they consider new technology often in generic terms and use cases. Oh that new tech idea? It’s better than everything you’ve been doing. Let’s adopt it everywhere. It’s the new best pattern. Then you get down to specifics of usage and the engineers have built terrible patterns of specifics off a promised generic that doesn’t exist.

I’m reading Edward Tufte’s Visual Explanations and the depth makes it a slow read. It’s like a museum. It takes ten minutes to read a page. I’m exhausted after only a few pages (rooms) and can come back for multiple days to a single topic.

The right data structure precipitates elegance and performance. “Re-think the data structure, gain better insights in the distinction between how the data is produced and how the data is consumed.”
