Autonomic computing

A interesting term and many interesting papers mentioned about the concept of autonomic computing. The key of autonomic computing is: self-managing of distributed resources.


To manage distributed resources, there must be an algorithm. The algorithm can be separated into four steps:

1. Monitor
2. Analyze
3. Plan
4. Execute

The main algorithm is known as Monitor-Analyze-Plan-Execute (MAPE).

getaddrinfo

int getaddrinfo( const char* pHostName, const char* pServiceName,  const struct addrinfo* pHints,
                         struct addrinfo **pResults);

getaddrinfo() 用來取得 host 上某 service 的一系列的 IP addresses 和 port numbers。

舉例來說

struct addrinfo hints, *result;
memset(&hints, 0, sizeof(hints));
hints.ai_family = PF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;

int error = getaddrinfo("www.kame.net", "http", &hints, &result);

bash complete 怎麼使用

Bash complete 的概念是，將某些 regression expression 與某個指令做連結，如此一來，就可以對該指令使用 tab tab 來 auto-completion。


先看一個 example：
假設我的家目錄底下有 A.cpp, B.cpp C.cpp 這些檔案


$ ls
A.cpp B.cpp C.cpp


建立一個新的可執行檔，叫做 example，我們之後要讓 example 可以跟 *.cpp 做 auto-completion

$ touch example
$ chmod +x example



建立連結：

$ complete -f -X '!*.cpp'example



馬上來實驗：

$ example [tab] [tab]
A.cpp B.cpp C.cpp
