Rescan-scsi-bus and slow DVD drives

For reasons that fail my, my internal SATA DVD drive is very seldom seen by the kernel at startup. My guess is that it takes very long to start, and the kernel doesn't wait that long before deciding that it had all SCSI devices, so it misses it. It's actually very annoying, since you can't use the drive at all. After digging around, I finally stumbled on the rescan-scsi-bus tool from the scsitools package. Running (as root, of course)
~ rescan-scsi-bus -w -l
(sometimes two or three times) is enough to get the device back up, with the /dev/dvd udev symlink.

Hope this'll help !

Release 0.13 of ctioga2

Today is ctioga2's release. Unlike most other release, this one does not bring many visible features, but quite a few changes nevertheless, including:
  • finally customizable output PDF resolution, which was asked some time ago
  • ways to average successive Y values (for the same X value), setting the error bars to the standard deviation
  • handling of histograms with missing X values (SF issue #1)
  • improvements in the emacs mode (including contextual help)

As usual, the new version is available as a gem

Enjoy !
