How to read an RFC

Why I Ripped the Same CD 300 Times
I collect music by buying physical CDs, digitizing them with Exact Audio Copy , and scanning the artwork.

We cycled the Swiss part of the Rhine Cycleway last week, with our folding bikes neatly stowed in suitcases for the flight. A combination of cycle.travel (natch), the Cicerone guide, and the excellent MapOut app guided us safely along the way: a very modern combination of mapping styles.

Whole House Fan and Evaporative Cooler
In dry climates it's common for people to use evaporative ("swamp") coolers; same idea as sweat evaporating off your skin cooling you off. The downside is that they increase humidity in the air, and if it's already pretty humid then that can make things uncomfortable. This means evaporative coolers are rarely used…

A Parable by Dijkstra (1973)
