Using Odvr for Olympus Digital Voice Recorder (VN-960PC)

First install libsndfile-devel

#  yum install libsndfile-devel

Compile and install:

 odvr-0.1.5 $ sudo make install
Making odvr_icons.h
gcc -g -O2 -Wall `pkg-config gtk+-2.0 --cflags`   -c -o odvr_icons.o odvr_icons.c
gcc -g -O2 -Wall `pkg-config gtk+-2.0 --cflags`   -c -o gui.o gui.c
gcc -g -O2 -Wall `pkg-config gtk+-2.0 --cflags`   -c -o odvr_gui.o odvr_gui.c
gcc -g -O2 -Wall `pkg-config gtk+-2.0 --cflags`   -c -o odvr_date.o odvr_date.c

install -o root -g root -m 755 odvr /usr/local/bin
install -o root -g root -m 755 odvr-gui /usr/local/bin

copy 41-odvr.rules to/etc/udev/rules.d/ and modify (for Fedora)...

$ cat /etc/udev/rules.d/41-odvr.rules
SUBSYSTEM=="usb", ATTR{idVendor}=="07b4", ATTR{idProduct}=="020d", ACTION=="add", GROUP="audio", MODE="0664"

add the 'user' to audio group; then log out and log in to make it effective

usermod -a -G audio user

useful commands:

lsusb
ls -l /dev/bus/usb/002
odvr -l
odvr-gui

Perl one liner to delete or replace a line in a file

Delete a matching line from a file:

perl -ni -e 'print unless /pattern/' filename

Replace a matching pattern to another:

perl -pi -e "s/matchingpattern/newpattern/" filename

Remove duplicate lines:

 perl -i -ne 'print unless $seen{$_}++' filename 

Perl options:

-n: while (<>) { ... # your script}
-p: while (<>) { ... # your script } continue { print or die "-p destination: $!\n";}
-i: in place

Fedora 14

I have recently upgraded my computers to Fedora 14, so far it seems to be more responsive than the previous version. Especially compare to Fedora 12, which after using a couple of days it become really slow.
