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

# zypper in rhythmbox2. 將音樂同步到iPod中:
我是透過ibook，這應該沒什麼好說的。 :p3.開啟rhythmbox:
開啟rhythmbox後，馬上偵測到了我的iPod，並可以播放音樂了，中文顯示沒問題，也能把專輯封面顯示出來感覺就好像是用iTune播放，hey OpenSUSE11.3 is awesome!

wget http://softlayer.dl.sourceforge.net/project/ss5/ss5/3.7.9-1/ss5-3.7.9-1.tar.gz
tar zxvf ss5-3.7.9-1.tar.gz
[root@server2 src]# tar zxvf ss5-3.7.9-1.tar.gz[root@server2 ss5-3.7.9]# ./configure[root@server2 ss5-3.7.9]# make[root@server2 ss5-3.7.9]# make install
找到auth與permit並將註解取消，注意我並沒有enable使用者需做認證的機制。[root@server2 ~]# vi /etc/opt/ss5/ss5.conf
# SHost SPort Authenticationauth 0.0.0.0/0 - -# Auth SHost SPort DHost DPort Fixup Group Band ExpDatepermit - 0.0.0.0/0 - 0.0.0.0/0 - - - - -
[root@server2 ~]# chkconfig --add ss5[root@server2 ~]# chkconfig ss5 on[root@server2 ~]# /etc/init.d/ss5 startdoneting ss5... [ OK ][root@server2 ~]#
最後可透過FireFox來測試Socks4/5.
工具->選項->進階->設定->手動設定Proxy:SOCKS主機: x.x.x.x Port: 1080並選擇SOCKS v4或是SOCKS v5
