While many web users don’t know that utm in a URL stands for Urchin Traffic Monitor, there are also Red Hat users who don’t realise that yum stands for Yellowdog Updater, Modified.
I not only remember it, it still makes me sick that they've replaced "yum", a project with a name that rolls smoothly off the tongue like no other, with "dnf", a project name that has all the grace of a running camel. (Also, it makes me sad that Seth's lovely project will be forgotten now that he's gone.)
