I've finally got my MSI-branded webcam working with Skype 2.2 on Ubuntu 10.10, with help from here.
All it took was a simple wrapper script to invoke an extra library.

Comodo Time Machine
If it gets stuck on booting, with messages that end up with 'Too many bad sectors', then you just need to rebuild the MBR.
From Hiren, run
mbrfix /drive <n> fixmbr
where <n> is the drive number, possibly 0 for C: — check that first with
mbrfix /drive <n> driveinfo
Printing booklets
To convert a PDF, such as http://www.justice.gov.uk/downloads/global/forms/opg/EPA101_Mar10_Web.pdf, to print as a booklet on Linux, try these steps:
pdftops x.pdf x.pspsbook x.ps x-book.psps2pdf x-book.ps x-book.pdf- acroread x-book.pdf
and then use acroread to print it 2-up (2 pages per sheet, duplex tumble). The command acroread generates is (all on one line):
lpr -P HL-5250DN -o OptionTrays=1Trays -o PageSize=A4 -o PageRegion=A4 -o CAPT=Low -o BRMediaType=Plain -o InputSlot=AutoSelect -o ManualFeed=False -o Duplex=DuplexTumble -o TonerSaveMode=On -o Sleep=PrinterDefault -o ScreenLock=True -o BRLanguageLevel=L3
so it should be possible to use lpr directly (but I haven't tried that).
