The guy you see to the left. Electrical/electronics engineering student mostly doing embedded development. Linux user since '05.

You might want to check what I am up to on my blog (in Portuguese mostly), my Twitter or my GitHub, or my skills are available on LinkedIn. Alternatively, if you want to see what I'm listening to, check my last.fm or Spotify profiles.

If you have any doubt/problem about my questions/answers, comment on them.

I will always try to comment why did I downvote, and will remove those downvotes if questions/answers are subsequently improved.

You probably will need to roll your own, it should be quite easy e.g. with Python + scipy/scikit-image or with Octave.

comment Swap appears to not be in use
From your dmesg it seems that the hard drive is failing, then the system remounts it as read-only. Can you install smartmontools and then run smartctl -a /dev/sda?

Does you distro provide prebuilt packages for the VirtualBox modules (if so, use those)? What happens if you modprobe vboxdrv manually?

comment Is LILO still usable on modern PC?
I remember using LILO around 2010 or 2011 on a then-current Core 2 Duo. I guess it should still work (disconsidering UEFI etc..), the PC architecture has not changed that much.

Ubuntu 8.10 is ancient, maybe it has problems with larger HDs.

This question is quite confusing. Is Linux installed in the laptop's internal hard drive or on the external one?
