What has the author Ole Torvalds written?

You're likely thinking of Linus Torvalds, the creator of the Linux kernel.

Ole Torvalds is a Finnish writer and journalist, not related to Linus. He has written a number of books, including:

* The History of the Helsinki Philharmonic Orchestra (1995)

* The Finnish Symphony Orchestra (2000)

* The Finnish National Opera (2005)

It's easy to get confused as both names are quite similar!
