shared libraries: liblzma.so.0: cannot open shared object file: No such file or這個問題將導致zypper指令往後無法執行！解決的方法如下：
directory
1. Install:# zypper in gsynaptics2. 檢查/etc/X11/xorg.conf在InputDevice的section中應該會有"SHMConfig" "on"75 Section "InputDevice"76 Driver "synaptics"77 Identifier "Mouse[1]"78 Option "Buttons" "5"79 Option "Device" "/dev/input/mice"80 Option "Emulate3Buttons" "on"81 Option "HorizScrollDelta" "0"82 Option "InputFashion" "Mouse"83 Option "Name" "Synaptics;Touchpad"84 Option "Protocol" "explorerps/2"85 Option "SHMConfig" "on"86 Option "Vendor" "Sysp"87 Option "ZAxisMapping" "4 5"88 EndSection3. 不用重新開機至"電腦"->"控制中心"->"硬體" 點選Touchpad or Mouse就可以設定了。

1. Uncompress 2010_1215_RT3572_Linux_STA_v2.5.0.0.DPO.bz22. Plug in WUSB600N to your Linux box.3. To execute "demsg" command to examine the vendor id and product id of WUSB600N. (it should be 1737/0079)4. Added {USB_DEVICE(0×1737,0×0079)}, /* Linksys WUSB600N v2 */ to the /common/rtusb_dev_id.c file5. Modified /os/linux/config.mk file to give you WPA encryption:# Support Wpa_SupplicantHAS_WPA_SUPPLICANT=y# Support Native WpaSupplicant for Network MagangerHAS_NATIVE_WPA_SUPPLICANT_SUPPORT=y6. # make && make install && reboot7. After system reboot successfully then plug in the WUSB600N to the Linux box again, and to execute "ifconfig -a" command then you will see the new device ra0
Pdsh is a an efficient, multithreaded remote shell client which executes commands on multiple remote hosts in parallel. Pdsh implements dynamically loadable modules for extended functionality such as new remote shell services and remote host selection.
1. Install pdsh on the Server.
2. Import ssh key of Server1 to the node1 and node2.
3. Add hostname-to-IPaddress of node1/node2 in /etc/hosts on Server1.
4. To execute: pdsh -w ssh:root@node[1,2] ls 2> /dev/null then node1 and node2 will to execute ls command and report to the Server1 as following:
lawrence@suse:~/.ssh> pdsh -w ssh:root@node[1,2] ls 2> /dev/null
node1: anaconda-ks.cfg
node1: Desktop
node1: id_rsa.pub
node1: install.log
node1: install.log.syslog
node2: anaconda-ks.cfg
node2: bin
node2: conf-examples
node2: cpulimit-1.1.tar.gz
node2: cpulimit.tar.gz
node2: Desktop
node2: id_rsa.pub
node2: install.log
node2: install.log.syslog
node2: mibs
node2: mibs_20100925.rar
5. Combine multiple commands:
lawrence@suse:~/.ssh> pdsh -w ssh:root@node[1,2] "cd /tmp;ls" 2> /dev/null
node1: pulse-Bk60xcI9xlDq
node1: virtual-root.pHV8bR

1. 準備某一Linux版本的live CD，Fedora 14是個不錯的選擇！2. 用Live CD開完機後，確定預升級的檔案系統處於無掛載的狀態。3. 利用tune2fs加上ext4的attribute：# tune2fs -O extents,uninit_bg,dir_index [device file]4.檢查檔案系統：# fsck -pf [device file]5. 掛載:# mount -t ext4 [device file] [mount point]6. 修改/etc/fstab後，重新開機。
1. 相容Ext32. 單一檔案大小可到16TB，檔案系統可支援到1EB3. 新的存放方式，增加檔案讀寫速度
1. 開啟/boot/grub/menu.lst2. 新增kernel參數如下:2.1 noht -> 不work....2.2 maxcpus=1 -> work!
echo "0" > /sys/devices/system/node/node0/cpu1/online
全速:
echo "performance" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
低速省電:
echo "powersave" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
userspace:
echo "userspace" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
(需配合cpuspeed daemon)
ondemand:
echo "ondemand" > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
1. 買個Prolific PL2303的USB to RS232 console: 似乎很多家都是用他的chipset，至少我手邊的兩家不同廠商都是。2. 到這裡下載driver，請注意它有區分10.6.x與104.x/10.5.x！裝錯版本可是驅動不了的！
3. 裝好driver後將Mac開機後，插入USB to RS232 consoel。4. 至/dev目錄去檢查是否有多出一個usb device file，for example: /dev/tty.usbxxx。5. 開啟Mac終端機。6. 輸入 screen /dev/tty.usbxxx 9600，9600就是你的baud rate，至於怎麼用screen command請參考我以前的筆記。
1. 簡單且實用2. 跨平台(Windows/Mac/Linux/Mobile)3. 2GB免費空間

ATI doesn’t provide anymore repository for their binary drivers, so we have to build them on each needed system. When the 11.3 hits the street, the procedure was complex and not so easy, now with their 10.7 ( 8.753 ) version, it’s doable.
Terminator, multiple terminals in one window. The goal of this project is to produce a useful tool for arranging terminals. It is inspired by programs such as gnome-multi-term, quadkonsole, etc. in that the main focus is arranging terminals in grids (tabs is the most common default method, which Terminator also supports).
Ctrl-Shift-E: 新增terminal並垂直切割Ctrl-Shift-O: 新增terminal並水平切割Ctrl-Shift-P: 回到上一個terminalCtrl-Shift-N: 至下一個terminalCtrl-Shift-W: 關閉目前的terminalCtrl-Shift-Q: 結束terminatorF11: 全螢幕顯示
