Stuff I found on the internet that I have to disagree with.

(And no, I didn't ask for clarification. If the author posts things without supporting details it suggests they might lack the supporting details. I can be charitable and assume they don't really care about providing useful information, but …

Superficially, most of these are true.

Looking a little more deeply, most of them are also presented in a somewhat misleading way. A few set up a good punch-line. The Inheritance one, for example, is funny.

If the point is to force a …

I want to call out two huge problems with Python. I'm not the first to point these out, but they've been bothering me for a while.

1. Surprising Changes
2. Dependency Hell

I've provided them here to save folks from repeating these. They're now officially "known" and there's no point in repeating …

See https://github.com/slott56/py-web-tool

And https://pypi.org/project/py-web-lp/

I finally made the PyWeb LP tool installable from PyPI.

I need to fix the name of the GitHub repo (some day) to make it also say py-web-lp. I should also fixup my tag cloud to say pyweblp …

The typing module includes the mysterious-looking Annotated type hint. See https://docs.python.org/3/library/typing.html#typing.Annotated for details.

What does this do?

Why do I need it?

Where can I see examples?

This was a surprising thing (for me) to see. Surprising because -- after writing a book about functional programming, I'd forgotten that some of the ideas are actually really new to people.

(I've omitted the source of the quote because I want to reuse this without worrying about link rot. Some …

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.
