iTunes U favorit links

Here is just a list of my favorite iTunes links: MIT. Introduction […]
Jumped into Oracle Solaris 11 Express wagon
It’s not the news anymore that Oracle Solaris 11 Express has been released. Unsurprisingly it turned out to be a trivial task to upgrade from OpenSolaris (snv 134) and it was just a matter of updating the publisher and do usual image-update: Some time later:
My lovely SL500
My old friend SL500 has given me another gift just a few hours before my flight to Moscow from Irkutsk where I was replacing the robot module or Z-Drive assembly. So I rushed back to the customer’s site to find the following: The robot’s hand was frozen and standing still just opposite the slot it […]

Orphaned Dtrace, Fishworks and ZFS
First it was Bryan Cantrill and then Adam Leventhal who followed. After that the exodus had continued by Jeff Bonwick and Mike Shapiro both leaving Oracle.

Game over
As expected I’ve miserably failed in the second round and had to rush home from disturbing and drizzling railway station’s environment. My only hope is to receive the list of all questions since the ones I’ve seen looked very interesting and I’d love to answer them just for myself.
