comment How can I tell what audio chip is in my laptop?
AC97 is not a driver interface at all! The name comes from a hardware interface between the chipset and audio/modem components. See en.wikipedia.org/wiki/AC97

comment Play video from SAMBA share on Android--Any shared volum from Linux or Winodows
@AjoMathew Do you mean stutter? -- The video file on the server does not change, no matter the connection! If it's not enough bandwidth, it will stutter or buffer all too often.

I just found a VLC beta thing, which couldn't fast forward or skip back, etc. MX Player worked.

comment How do I determine if my controller is in IDE or AHCI mode in Linux?
of course it doesn't change anything on the disk itself, but the disk drivers can't talk to the controller the same way as before the switch... the next read/write doesn't fail?

Do disks not get screwed when you wakeup in IDE mode with AHCI driver? They stop working? Do they get back to normal when you switch to AHCI mode after wakeup?

comment How do you add a certificate authority (CA) to Ubuntu?
Wrong! You’re supposed to put it in /usr/local/share/ca-certificates and with a .crt ending.

comment Find packages installed from a certain repository with aptitude
I prefer ?any-version(), because ~narrow(pat1, pat2) is the same as ?any-version(pat1 pat2) and it supports ?any-version(pat1 pat2 pat3) without looking stupid.

comment Find packages installed from a certain repository with aptitude
Your aptitude search patterns are not good. – They select like this “list packages where one version is installed, and any other version exists in Debian” or “some version installed, and at least one version of that package available on non-Debian”. – What we look for is “the version installed is from Debian (or not)”. This has to be done with ?narrow() or ?any-version().
