Central to OO design is "encapsulation." It's so central it is part of several separate principles.

In the S. O. L. I. D. design principles it's the Interface Segregation Principle. And a significant part of the Single Responsibility Principle.

In some cases, Python n00bz -- folks who already know some OO …

Let's reach way, way back. 1989 - 1990. This will let me talk about OO programming and Python Type Hints. (really) And doing OO design for things that are as pervasive (and transparent) as air. Things that need to be part of a design, but don't appear in any documentation.

In …

The question was "Favorite Design Patterns."

This is tricky because -- well -- so many patterns appear and re-appear in software. Picking a few from the vast world of patterns is fraught with difficulties.

Here are some thoughts:

• Code Quality - Which Implementation is "Better"?
• State-Based Object Modeling
• Functional Programming and Finite State …

Few things are as distracting as those god-awful side quests.

In this case, I had to search out all of the examples in my new book drafts.

Reaching back to 2008. Yes. Decade(s) ago. Python 2.5.

I was reminded of this when a former colleague pinged me about this: https://github.com/slott56/TigerShark.

Yes, it's an X12/EDI message parsing library from -- well -- decades ago.

Here's how to recognize a Faerie Dust request:

1. We have identified a problem. It can be with almost anything: scalability, reliability, auditability, any Quality Measure.
2. We're pursuing a specific technology. Typically, something that has the lowest impact on our architecture.
3. We can't address anything other than this specific technology variation …

I've been trying to help some folks who have a "search" algorithm that's slow.

They know it's slow -- that's pretty obvious.

They're -- unfortunately -- sure that asyncio will help. That's not an obvious conclusion. It involves no useful research. Indeed, that's a kind of magical thinking. Which leads me to consider …

This is a problem folks new to Python have, and sometimes can't articulate that they have it.

They don't know which package is the "right" one to use. Tox vs. Nox. Click vs. Argparse vs. getopts? What's the "best" choice?

• Response 1. The whole Python ecosystem is chaos and the …

Happy birthday, mom. Glad to see you're still doing well, avoiding the complications of COVID-19.

You asked what it was I did for a living. Emphasis on the past tense, now that we're both fully retired old people.

I have to confess that it's not easy describing high-tech work. There's …

I'm in regular contact with a few folks who seem remarkably incurious. Seem. Perhaps they're curious about something other than software. I don't know. But I do know they're remarkably incurious about software. And are trying to write Python applications. I know some people don't sail out of sight of …
