  • If you hear white noise in your speakers and headphones while running Solaris 11 Express, do not waste 2 weeks, like I did, looking for software bugs in the audio driver. Just make sure your audio cables are not too close to the power cables (or apply some insulation).

  • While investigating performance problems in our Oracle ZFS appliances (read it here), one complain was that sometimes NFS/iSCSI operations were taking 5-20 seconds to return.

  • This American Life has a podcast called “When Patents Attack” that has drawn lots of deserved attention.
