Tests matter, but elegance and simplicity matter, too. Tony Hoare said, "There are two ways to write code: write code so simple there are obviously no bugs in it, or write code so complex that there are no obvious bugs in it." All

Not just one line, but often 3-4 lines, and when writing tests, it often completes 10+ lines for me, and I only have to make a few corrections, sometimes none at all. You have to read every line and character it suggests, but even so, it sa

It really pays the effort back, though, when you can figure out why something was done, beyond knowing the feature it was related to, which is all you get with a squash merge.

by dkarl 3y ago
I think squash merges are a last resort heavy-handed tool for dealing with developers who refuse to clean up their commit history before merging. Most developers can do better by hand. Git history should tell a simple, understandable story

I guess the way you describe it is the way I like to work, keeping my object model in code close to the relational model to minimize the mental and performance cost of mapping back and forth, and using a SQL library to minimize boilerplate.

by dkarl 3y ago
If you are sophisticated enough to design a good relational model and use an ORM to generate it, what does an ORM give you? Serious question. The answers I've seen typically stress the advantages for developers who are uncomfortable wi

For this reason I love drawing diagrams on whiteboards and absolutely hate taking the step of putting them into a wiki/README/etc. One thing I miss about in-office work is that people would spontaneously draw diagrams in meetings.

It's insane to hear attrition used as an excuse for architectural decisions, but I've seen it firsthand.

If you're transpiling to Javascript, or running type-hinted Python, the runtime platform doesn't know about the type-checking you did at compile time.

That's a completely reasonable compromise. I think the reason it doesn't get mentioned is that nobody would bother doing it under those constraints. Scientists would not choose to work on it at such great personal cost, and the fi
