Helo: After changing "involuntarily" some of the graphics parameters with the command par() (I did not know that changes with this command are permanent), now when I made a plot of the survival Kaplan-Meier function, the Y axis does not start at 1, and the X axis does starts at 0. The commands that I use are: library(surviv...

Hello list, Did an update to the latest AMD drivers (11-9_vista64_win7_64_dd_ccc_ocl) and was pleasantly surprised to find that I can reboot my passthrough domU! Firstly, the reboot was triggered involuntarily shortly (20 seconds) AFTER the SUCCESSFUL driver update. The only thing logged was this: (XEN) io.c:194:d5 MMIO emulation failed @ 0010:fffff800036c7d00: 0f 28 04 10 0f 28 The domU and qemu spontaneously disappeared (the qemu log just stops there and logs nothing), and reappeared, as a...

...most recent Xen Summit, Thomas Friebel presented a paper ("Preventing Guests from Spinning Around", http://xen.org/files/xensummitboston08/LHP.pdf) investigating the interactions between spinlocks and virtual machines. Specifically, he looked at what happens when a lock-holding VCPU gets involuntarily preempted. The obvious first order effect is that while the VCPU is not running, the effective critical region time goes from being microseconds to milliseconds, until it gets scheduled again. This increases the chance that there will be be contention, and the contending VCPU will waste time spin...

...omeone do anything on your Linux (or UNIX) mail servers to convert darn proprietary MS Outlook winmail.dat attachments your users may receive (occasionally if lucky) into readable e-mail format. I know quick answer to my question (good quick answer would probably be: just trash them). Still, being involuntarily immersed into corporate world (even at Educational institution), I'd like to know what clever and wise people do. I can refer my users to some free online converters and get over with that. The only thing that makes me think about potentially investing more effort into dealing with this garbage...

...nt. But, security has many levels. And the first level is recognition of the threat. Whether we recognize it or not. Whether we agree of disagree with the politics that lie beneath this situation or not; Whether we consider this a non-technical issue or not; By virtue of our employment we are all involuntarily caught up in a global conflict between the agents of extremely powerful states versus the talents, minds and beliefs of principled individuals. For better or for worse the chosen battleground is the software we use and the hardware we run it upon. It is my belief that we as a community are not we...

Hello, This patch series adds an initial implementation of restriper (it''s a clever name for relocation framework that allows to do selective profile changing and selective balancing with some goodies like pausing/resuming and reporting progress to the user. Profile changing is global (per-FS) so far, per-subvolume profiles require some discussion and can be implemented in future.
