Estimating how long it takes to build software – or even how much effort a sprint is – is pretty hard. Estimates often turn out to be too optimistic, and mispredictions can be pretty hard to explain to management. I know why this is so – Michael Wolfe on Quora has a great analogy (there is even an interesting discussion on Reddit), which I agree with. But I'm wondering whether there's an easier analogy.
EuRuKo 2019 – the largest Ruby conference in Europe, took place on the 21st and 22nd of June. I gave a talk on the 21st about what causes Ruby memory bloat (where I also reported new findings since I first blogged about the issue), as well as about Fullstaq Ruby. Fullstaq Ruby is a server-optimized Ruby distribution that's faster, uses less memory, and is easier to security-patch thanks to being distributed via RPMs and DEBs.
