Well, my newest Master Class was a hit. As it is with my live work with programmers, we start with all the technical issues, then pivot hard in the last 30% to the deeper interpersonal problems.

When we use LLMs to generate code, we get Common Practice amplified and thrown back into our faces. We also entrench Common Practice.
So... Which practices are common? Would you like more or less of that?

With a code sample of computing the most frequently repeated letter in a string in Java, @venkats.bsky.social shows us an example of code that looks complicated (even ridiculous), but is truly merely unfamiliar to the typical reader. #codecamp

Excellent! If @markrichardssa.bsky.social has it right and programmers will be nudged towards architectural responsibilities, it seems to me that the lessons we can learn from Evolutionary Design will be invaluable. That will make it easier to trust the programmers to whom they delegate decisions.

Good news: we already knew what to do. Bad news: we didn't do it. More bad news: we had to rediscover it in order to notice that didn't do it.
Good news: we can still do it.

Evolutionary Design, and in particular TDD, can help folks learn both how to build Microservices in a Single Process and why that might be wise.
And this is merely a synonym for Modular Monolith. #codecamp

I expected @kevlin.bsky.social to say it, and he did. The problem isn't the Modular Monolith so much as the reason to want one.
