Brendan Gregg made an unusual discovery, shouting a HD produces pikes of latency. We’ll see sound proof data centers now? Another point to solid-state drivers.
I wonder if playing loud music near my computer makes IO slower.
InfoBrasil is a tradicional IT business event in my city. This year we got a space for Open Source and Free Software where I did a presentation about OpenSolaris. I posted our grid yesterday.
That was my first presentation about OpenSolaris so I focused to showing that OpenSolaris 2008.5 is a GNU/OpenSolaris distribution but you can access features like ZFS, DTrace and Zones. I used those slides that Tirthankar Das, Solaris Cluster Engineering at Sun Microsystems, did for FISL 2008. Most of the audience was composed from students and they showed very impressed with ZFS. In my next OpenSolaris presentation I’ll try to focus more on ZFS demos. ;) Someone in the audience did a random number generator code live. We used it to prize some OpenSolaris gifts like tshirts and sticks. :D
I hope that for now on that we can use better this space and for establish a good dialog between communities, governments and enterprises.
All photos ares avaliable at my personal album for that event.

Solaris Containers, OS level virtualization for Solaris
E só para lembrar:
