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 …
more ...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:
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.
Once upon a time, it was a manual check of code in the book to be sure it made sense.
Ugh. Not …
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.
Short answer: Parsing X12 …
Behave fixtures totally rock for testing complex applications.
I had been doing them wrong. Doing them right is simpler.
I'm a fan of the Gherkin language for specifying the behavior of software.
Scenario: Works for Me Given a configuration When a request is made Then the response can …
Some background: FAERIE DUST™, Obstinate Idiocy, Obstinate Idiocy, Expanded, and even Permutations, Combinations and Frustrations. I want to set up algorithm design as the diametric opposite of Obstinate Stupidity. To do that, let's look at Obstinate Stupidity.
The theme?
We did something wrong, and we don't want to fix it …more ...
Real Question (somewhat abbreviated): "My algorithm performs badly, do I need asyncio?"
Short answer: No.
Long answer: Sigh. No. Do you need a slap upside the head?
Here's how it plays out:
Q: "We figured that if we 'parallelize' it, then we can apply multiple cores, and it will run …
more ...When I talk about functional programming in Python, folks like to look for place where functional programming isn't appropriate. They latch onto finite-state automata (FSA) because "state" of an automata doesn't seem to fit with stateless objects used in functional programming.
This is a false dichotomy.
It's emphatically false in …
more ...The issue of permutations and combinations is sometimes funny.
Not funny weird. But, funny "haha."
I received an email with 100's of words and 10 attachments. (10. Really.) The subject was how best to enumerate 6! permutations of something or other. With a goal of comparing some optimization algorithm with …
more ...See Obstinate Idiocy for some background.
Here are three warning signs I was able to deduce.
To which I can now add two more.
Symptom 4 of Obstinate Idiocy is that all questions are rhetorical and they often come with pre-argued answers …
