Didn't sleep too much today (actually I spent the whole night awake trying to understand the simple program presented on Wikipedia for the generation of the Farey Series (as Hardy & Wright call them). Finally, looking at my copy of "Concrete Mathematics", I discovered a "bonus problem" (read: a very hard problem) that has a deceivingly simple solution that I was looking for the past few days to justify the program correctness.

Latter, I went with my dad to "Galeria do Rock" to grab myself a copy of Pain of Salvation's "Be" (DVD+CD), Tristania's "Widow's Weeds" and "Beyond the Veil", and Opeth's "Deliverance".
