I need to write up my experience. But I'm trying it out. Linux needs something like this. I've had issues, posted traces and had them fixed in seconds. Pretty damn amazing. I'd love to see a bigger team involved though.
Confidence intervals don’t have precise timelines associated with them. Sometimes you know exactly what the problem is when you hear the symptoms.
We always balance new work versus cleanup. I always have a laundry list of beefs with my own work. You often have a sneaking suspicion that this piece of code is wrong in a manner you can’t quite put your finger on. Or you do but a new customer is trumping a hypothetical error. Or ten people are blocked waiting for you to merge some other feature. And then someone gives you a test case and you know exactly what is wrong with it. Sometimes that’s fixing a null check, an off by one error, or sorting results. And sometimes the repro case basically writes itself.
