A single poorly-made decision can have profound ripple-effects. Once your stuck with it, you make accommodations, hacks and work-arounds. Eventually, things work, but the result is less than ideal.

Changing tack requires sometimes pervasive rework to the application. How can we reduce the risks and improve the value created?

First, the definition. A use case describes an actor's interaction with a system to create business value. There are three parts: Actor, Interaction and Business Value.

1. Not Interactive.

1.1. The use case is just features and technical attributes with no actor interaction expressed.

1.2. The use case is …

Objects are everywhere.

Weirdly, some people can't see them. I guess they live in a rarified, HP Lovecraftian world of pure action inhabited by amorphous things that can't be properly called "beings" but rather "doings" because they're pure activity with no existence.

Read "Hypnos". "They were sensations, yet within them …

After reverse engineering procedural code in C, VB or even Python, I'm finding that procedural programming inevitably leads to bad, bad code-rot.

Consider some of the common design patterns.

Strategy. Confronted with alternative strategy choices, a purely procedural code solution is either

• If-statements everywhere the strategy is involved.
• Block comments …

Too much of programming is intimately tied up with the tools to support the development of the software.

Example 1. I was told -- with absolute and fierce conviction -- that VB may suck as a language, but Visual Studio more than makes up for the obvious problems. For some people, Tools …

Another case study on TDRE.

Provided: 2,938 lines of Python code which process a handful of large files to create a number of outputs. [Details can't be disclosed.]

Objective: Refactor to distinguish between the overall sequence of transformational steps and the details of each individual step.

Read this first: "There is something I find interesting about online discussions around performance issues..." It's about Stack Overflow, specifically. Apparently, someone didn't get their question answered and decided it was better to gripe than to rewrite the question.

Let's look at their response in pieces.

"people try to gang …

I'll be wearing my "official" Stack Overflow shirt. I'll try to grab a seat by the door, also, to be easy to find.

A joyous milestone today. Removed much of our pre-Piston RESTful web services code.

We started with the Django-REST Interface. While nice, it imposed a number of restrictions that were onerous. In particular, we have a lot of non-model responses. They're model-like data that we serialize to be compatible with …

This is a fair-to-partly silly question that shows up on places like StackOverflow once in a while.

Python is used widely and pretty heavily.

It's a built-in feature to many operating systems in common use. The exception, of course, is Windows.

I just found out -- the hard way -- that Python …
