Basic overview of computers

IP address
-Every computer has its own IP address (unique identifier).
-Analog: person's NRIC number
-For example: 74.125.24.103

Hostname
-The purpose of assigning hostname to IP address is to make them easier for people to remember.
-Example of hostname: www.google.com, GHSEP, Eagle
-Analog: Alice

Domain Name System (DNS)  
-The Domain Name System (DNS) is the internet's version of the Yellow Pages.
-Is to find the IP address associated with hostname (e.g. Eagle maps to 192.168.1.88).

Dynamic Host Configuration Protocol (DHCP)  
-A DHCP Server is a network server that automatically provides and assigns IP addresses, default gateways and other network parameters to client computers.

Firewall
-Allow you to block or allow certain types of network traffic for incoming & outgoing.
 
A ping is a signal sent to a host that requests a response (e.g. ping Eagle8).

30分钟学会下围棋

1.如果一个棋子没有气也就是死棋，需要在棋盘上拿掉。也就是说，我们要想吃掉对方的子就必须将对方棋子所有的气都堵上。

2.特别注意的是：没有气的地方是不能放棋子的，除非放上棋子可以吃掉对方的棋子才能落子。只要有气的位置就可以放子。

3.有两个眼就代表你的这一片区域的棋子都是有气的，不可能被吃掉，所以就是活棋。
在围棋中，为什么说有两个眼的棋是活棋，因为就算它四周都被白子围了，但是由于里面有两个空（气），把一个白子放进其中一空，但是由于白子四周被围，一放进去就死了（实际上那个地方叫做禁着点，是不能放子的）。所以白子根本不能将黑子的气全收，黑子活。

七字口诀
#金角银边草肚皮

盘上落子价值是：角最大（金角），边其次（银边），中腹最小（草肚皮）。 

#三线拆二有根基

三线拆二能围住一定的根据地。  

#立二拆三搭配好

立起来的两个子，可以拆三。这个结构很好。  

#莫压四路休爬二

不要压着对方爬四路，自己不要在二路爬。

#台象生根点胜托

台象（棋形的名字）想要原地生根，点入对方的二路比托要好。

甩手功

健康就是财富!

李鳳山師父平甩功十分鐘練習

注释:

練的時候全身放鬆, 手自然擺動；但雖說是放鬆, 又鬆中有動, 而非完全的靜止；動中又有鬆, 也非用力的動態, 所以是一種很細緻的運動, 而且陰陽調和、剛柔並濟。
