i have been busy for changing diapers, cleaning milk bottles for those months.

OK, everything is fine!
OK, i need to get back to work! Do Dance, Dance, and Dance.

lspci ( lists pci device)
lsusb ( lists usb device)
lsscsi ( lists scsi device)
systool
fdisk -l ( lists hard drive)
dmidecode ( lists hardware model, serial number, cpu, memory. This command was handy when i needed to find serial number without a visit to data center)
cat /proc/cpuinfo ( more on cpu)
cat /proc/meminfo ( more on memory)
you can find a lot of information by using dmesg|more or grep what you are looking
e.g.
dmesg | egrep ‘(SCSI|scsi0|ide0|hda|sda|serio|mice|eth0|eth1)’
cat /proc/cpuinfo
cat /proc/meminfo

真正全然陌生了的安靜安寧的感覺。
午飯時候的尖東海傍, 細雨落在廖廖數人的海傍公園。維港對岸浸淫在一片雨霧之中, 腳下海浪輕拍著, 渡輪緩緩的飄浮來往……
已是多少歲月了, 未嘗如此安然的感覺。
文化中心的婚姻登記處, 剛剛遞交了結婚申報表。
心中安寧, 是因為我已決定了我的去向。
朋友們, 祝福我們吧…
BB、bb, 我們攜手邁步吧, 途中也許風風雨雨, 我們攜手並肩上吧…
好了, 下一站醫院產房!
