no excuses today.


At Home.

School starts again, yesterday we went for a nice 5 mile walk around the basingstoke canal at Dogmersfield, really nice day, dogs behaved, amazing scenery - ancient houses in traditional maintained english land
 the walk.


At Work.

I had a realtime discussion today, one I have had many times. Running a process in the Realtime scheduling class does not make it a realtime process! You need to follow the realtime rules  to ensure you application doesn't do any thing that might not have a bounded response time. Disk drives can take seconds to do recovery of a bad block, bad for your pseudo realtime application if it is paging in from that block..... There are cluster implementations that have had problems over the years from not following the rules, obviously as the sun cluster sustainers sit near me Sun Cluster does not have that failing.

Syseventd is doing my head in!  how does the devfsadm_mod channel subscribe to EC_devfs events... more debug code required. Like many technical subjects that you think you understand the more you look the more you realise you don't understand it at all..


In Between.

0 miles in the smart.

15 miles on the bike - 180 beats/minute dance music seems to up the speed a bit, but my legs do ache now, any recommendations for good music to listen to?
