RIP Jane Goodall. I used to read about her in the old National Geographic issues we had at our summer cabin.
The Far Side cartoon features two chimpanzees in a tree, with one discovering a blonde hair on the other, asking, "Conducting a little more 'research' with that Jane Goodall tramp?"

Anyone else write a lot of Xcode code snippets? I haven't seen a description of the "Availability" choices, showing "This applies here, but not there."

TDD isn't just "write a test first."
It's also knowing _which_ test matters most.

I am not happy, Apple
Future versions of macOS will no longer support Time Capsule disks for Time Machine backups.

Xcode supports some automated refactoring — but the options are often disabled when you need them.
They're buried, unpredictable, and easy to give up on. So…

In the industry, legacy code is often used as a slang term for difficult-to-change code that we don't understand. But over years of working with teams, helping them get past serious code problems, I've arrived at a different definition. To me, legacy code is simply code without tests. I've gotten some grief for this definition. What do tests have to do with whether code is bad? To me, the answer is straightforward, and it is a point that I elaborate throughout the book: Code without tests is bad code. It doesn't matter how well written it is; it doesn't matter how pretty or object-oriented or well-encapsulated it is. With tests, we can change the behavior of our code quickly and verifiably. Without them, we really don't know if our code is getting better or worse. You might think that this is severe. What about clean code? If a code base is very clean and well structured, isn't that enough? Well, make no mistake. I love clean code. I love it more than most people I know, but while clean code is good, it's not enough.
