TDD pro-tip: demeter chains are anti-microtestable. What is a demeter chain? It’s code where we talk to a collaborator’s collaborator. U can look up the origins of the name in your copious free time, but in regular code, it looks like this: x = a.b.c.d.e.f; each one of those dots is a link in a […]

TDD pro-tip: any "time" u refer to a clock, be on the lookout. It’s a time — I just can’t help myself — to seriously microtest your way through. If you have to talk about "now", consider whether you want to be able to pass a clock rather than call the system. For the price

We spoke of two questions in the recent re-visiting of the money premise. How/why does TDD make changing layered branching logic faster? What’s the capital outlay to change to it? I’ll stall a little further on 2, but let’s do 1. Some provisos before we get started, and they’re pretty important. Proviso #1 We are

Time, this morning, to return to the underplayed TDD premise called the money premise. In one phrase: "We’re in this for the money." What does that mean?

So, in recent muses, i’ve tried to establish that our next step is a) restructuring economy to b) grow & keep geeks. How? What changes do I make in my org, assuming that I have restructured the economy to give me space to do so, to increase the org’s ability to grow and keep geeks?

Hill (@GeePawHill) August 12, 2018 #### Let’s go there. I believe we are consistently failing in the geek trade. By failing, I mean that we who

It seems to me that a very great deal of "agile" advice has an implicit prefix, "assuming your team is close to healthy," you should … The assumption of reasonable health just — to put it as gently as I can manage — doesn’t seem like the sort of assumption we should be making. The

Coaches, let’s talk about fear and — not the team — fear and the coach. I get to meet and speak with a lot of coaches, which pleases me. Because i’m an introvert with a taste for authenticity, I am also lucky enough to quite often get them in small groups or one-on-one where folks

Yesterday’s irritated blurt was a matter of feels, not an attempt to offer insight or ideas. I got some queries about it, so let me wipe that slate and be a little less irritated. For now, anyway. 🙂 In geekery — in all tool use beyond a certain point, but my focus here is on
