Is this a column? Not exactly, but a recent event made me realize that technology fails, and that sometimes we depend on that technology in very essential ways. Take heating. My heating failed (or appeared to) because of a failing SDHC card.

(Lots of interesting reading on ageing of SDHC cards you'll find here and here. And here.)
