comment Decode all records from wtmp
I have no audit log and no ausearch. I have big wtmp file, and last utility does not print all records from it. I just want to dump all records from existing wtmp.

comment The best “performance per watt” (MFLOPS/W) for CPU and GPU for the moment
Interesting numbers from GPUS AND THE FUTURE OF PARALLEL COMPUTING, Keckler 2011 (www.davidglasco.com/Papers/ieee-micro.pdf): there are 50 picoJoules (pJ) needed for one double-precision fused multiply-add (DFMA) in 2010 with 40 nm node, and the number will be 6-9 pJ in 2017 on 10 nm node. There is also some energy to store/read data in SRAM: 14 pJ in 2010 and 2 pJ in 2017.

comment “LV Status NOT available” after converting root from lvm2 to lvm2+raid1 (lvconvert --type raid1)
update-initramfs didn't include dm-raid into image; I needed to manually add this module to /etc/initramfs-tools/modules file.

Hauke, my first problem was that I can't boot after lvconvert. Part of it - is that i have no dm-raid module in initramfs.

insmod dm_raid helped but I still needed to do lvchange -ay ubuntu to boot.
