I've been pondering ways to help folks who clearly have no design skills at all. I've read their code. It's appalling.
Toward that end, I looked at some of the Code Kata links: the CodeKata page, Mark Needham's blog posting on code-kata, Rizky Farhan's Collection of Software Projects, jp.hamilton's Code Kata Resources.
They asked for code samples to act as best practices. I suggested to our sales folks that code samples and simple code "best practices" were completely inadequate. They need serious remedial skill-building in programming.
What started to percolate was organizing a periodic "code dojo" meeting to help them build skills without the onerous "teaching" (or worse, "lecturing") mode. Teaching OO design to working programmers is generally hard. Many programmers seem to have a starting point that isn't based on the requirements or any kind of rational design. It appears that many programmers start with a pretty random boilerplate program.
Teaching Java to COBOL Programmers
I remember struggling with COBOL programmers. Back in '02 (before Code Dojo existed), I had no real way to educate folks except a lot of one-on-one conversations. I tried to schedule code walkthroughs, but the project manager didn't like the idea, and cancelled them.
I was allowed a quick overview of J2EE concepts and how the web side of our application was going to be assembled, but that was it.
Even covering basic J2EE servlet concepts become a FAIL because the legacy web framework was a JSP hack-around. It didn't work well, couldn't easily be explained (or used). But it was entrenched, and therefore, had priority in everyone's mind.
No matter how many times I tried to review basic OO concepts, and some design approaches, there were problems.
Everyone wanted to start from "the top", with a "main program" that "simply read and wrote files." COBOL concepts. Java File I/O has a subtle complexity with lots of nested constructors. No one likes to see that as a beginner. Also, file parsing is -- in reality -- fairly hard, but COBOL provides a handy optimization via a fixed format record layout and lots of implicit conversions.
We're writing servlets that query a database. There was no mapping to the COBOL concepts everyone wanted to start with. A few lectures and presentations aren't helpful. Had I but known about Code Dojo, I would have suggested that. It might have worked.
The "Getting Started" Problem
Some Stack Overflow questions on design are really questions about "getting started". These cause me to wonder how to help people who are sure they know the language and syntax, but can't seem to get started writing anything useful "from scratch" (or de novo.)
I've heard from people have have UML class diagrams and still claim they don't know what to do next. They can't -- for some reason -- get started.
I think this is related. They have a limited, fixed set of programming templates. Learning a new language does not fit their limited set of templates. Perhaps Code Dojo could help these folks gain a new set of templates.
