In "Why Python?" I linked to a deep and sophisticated analysis of programming languages. Anyway, I thought it was a deep and sophisticated analysis.

I got a reply that shows how wrong I was. Here's the quote:

The point is that the Python ecosystem has a lot to offer. We …

People talk about CI/CD (Continuous Integration/Continuous Deployment).

They also need to talk about CM (Continuous Migration).

"Wait, what?" you ask.

I was told a horror story about a bad database schema migration. Let's call the author of the horror story HPL.

HPL related a tale of woeful conversion problems from a mismanaged schema migration.

This cropped up recently. It's part of a "replace Mongo with Relational DB" conversation.

What's (to me) very telling is that someone else published the five reasons in this …

I'm calling this the Composite Builder pattern. This may have other names, but I haven't seen them. It could simply be lack of research into prior art. I suspect this isn't very new. But I thought it was cool way to do some declarative Python programming.

Here's the concept.

Do you have a good project? Do you want to write? The acquisition folks at Packt are looking for this: "... demonstrate 4-5 projects over the course of the chapters in order to demonstrate how to build scalable Python projects from scratch. These projects cover some of the most important concepts …
