The latest batch:
I got my other half a Raspberry Pi for his birthday, so, of course, we then had to get several books about it. (I have building a supercomputer out of Raspberry Pis on my to do list, but then, doesn’t everybody?)
I got the Larbalestier after reading James Nicholl’s review, and the Cato after reading Scalzi’s Big Idea post. Reading blogs can be expensive.
