http://forums.freebsd.org/showthread.php?t=4708 And some driver program, like nvidia, doesn't aware of that, yet. So after recompilation, mouse and keyboard are not working.... and need to update the config manually.

An article to share how to organizate files as well as daily task, his approach is difference from me, but still worth to take a look
http://www.onlamp.com/lpt/a/6377 In contrast to the author experience, categories work for me. Spotlight or google desktop doesn't add value, I can just find it.

In Solaris, we can get stack trace even if binary is not compile with debug symbol, just run gdb with coredump: "gdb binary core", then can use "where" command in GBD console for that
Look like "bt" give you some result -

xmlwf, need to know if a XML document is well formed? (A configuration file maybe..)
mkfifo is the coolest one. Sure you know how to create a pipeline piping the output of grep to less or maybe even perl.
nl, add number for every line of a file

Linux Boot Process -
http://www.thegeekstuff.com/2011/02/linux-boot-process if you want to boot into something you can edit the boot parameters in grub:
"e" to edit
replace the boot parameters from ro xxxx xxxx to "rw init=/bin/bash"
and you'll be able to access a limited shell (no job control), then can run
ifconfig eth0 up
dhclient
to bring up network.
https://bugs.launchpad.net/ubuntu/+bug/430272/comments/24 If there is really disaster situation that grub fail, can try this to reinstall grub:
sudo mount /dev/sdXx /mnt
sudo mount -o bind /dev /mnt/dev
sudo mount -o bind /sys /mnt/sys
sudo mount -o bind /proc /mnt/proc
sudo chroot /mnt
Once at the prompt I reinstall grub:
Code:
grub-install /dev/sda
and then updated grub
Code:
update-grub
then Ctrl-D twice to exit, and reboot.
