Yikes! Realised once I got to the (blocked) level crossing in Thatcham that I did not have my wallet. The petrol tank is showing about 1/4 full and previous experience tells me that this is going to warn me that I’m running low very shortly. Well, at least I can read my email on the move, so it can’t all be bad…

Today on the course we finished looking at ZFS and began to look at DTrace. Not that I have anything against these two subjects or the SunOS zones, but why the heck should Sun produce things that are not capable of interacting well in the free OS world? They’re really cool ideas (even though BSD had jails before zones).

This might seem like a pointless rant and it might be - it’s great the ZFS has patents so that other proprietary systems cannot implement it - but this could be a little like the reason why Apple wouldn’t include Vorbis OGG in their iPod players - since there are patents around it - who can guarantee that some day Vorbis won’t decide to ask for fees for using OGG?

Personally I’d love it if ZFS and DTrace could be dual GPLv2/3 and CDDL licensed, then it’d probably be possible to implement it in the 2.6 kernel and the world would be sweet because we’d have nice standards and programs that can be used on a whole variety of platforms. As it stands, it’s currently a lot of work to create ZFS pools using fuse as there are lots of dependencies which have to be catered for.
