In the film industry, when we want to guess how much money a film is going to make, we think of similar films to compare it to and see how much money those made. Six months ago, I started a project to think of similar films for you. We rolled it out to our users a couple of weeks ago, and they love it. Quite apart from the films it recommends, my boss says that the way it displays the comparisons is by far the best that he's ever seen. The database it draws from only goes back a few years, so we managed to get budgeting approval to hire a team of interns for a few weeks to fill in the history. My company is probably paying about £10,000 to collect data for a system that I wrote, by myself, in six months while working on other projects. (That's not actually a lot of money, but my system one still thinks it is.)

Relatedly, I solved this bug while working on it, by delving deeper into the network stack than I ever have before.
