介紹

ppa  全名是 Personal Package Archives

https://launchpad.net/ubuntu/

Personal Package Archives (PPA) allow you to upload Ubuntu source packages to be built and published as an apt repository by Launchpad.

Ubuntu >= 9.10 才用到

使用的 Example

# corosync pacemaker libqb

!! 錯誤方式 !!

修改 /etc/apt/sources.list 加入

deb http://ppa.launchpad.net/asmartin/cluster-stable/ubuntu precise main

之後如果直接 apt-get 安 package 會有以下 Error

• Xming
• NX technology

Xming

http://sourceforge.net/projects/xming/

NX technology: (NeatX, freenx)
http://freenx.berlios.de/

nxproxy <----------> nxagent

Neatx - an open source NX implementation created by Google
http://code.google.com/p/neatx/downloads/list

freenx 與 NX Free Edt 的分別

freenx 安裝  <--- no connection limits, GPL
NX Free Edition <--2 connection

CPU instruction set

SSE4 (Streaming SIMD Extensions 4)   <-- 54 instructions

• SSE4.1  <-- 47 instructions
• SSE4.2  <-- 7 instructions
  • STTNI (STring and Text New Instructions)
  • CRC32
