I've heard some people are wondering about the title of my blog. Here's an explanation I gave in my previous blog:

It comes from a Japanese compound, 蛍 雪, (keisetsu), which is made up of the Chinese characters for fireflies and snow. It refers to scholars before electricity (and apparently candles) reading by the light of fireflies or the moon reflected in the snow. It means diligence in studying, and I thought it was a nice image.
