當我們有很多 processes 時，並想用實現 shared memory 處理共用資料時，就可以使用 shared memory，來實作。建立 shared memory 可以使用 mmap 或是 System V shmget，但根據 Stack Overflow 「How to use shared memory with Linux in C」回答，shmget 已經有點過時，mmap 則比較新和彈性。
Shared memory 讓我們可以建立一塊共用的記憶體空間，mmap 會回傳一塊記憶體空間的指標，型別是 void *，如果我們想要放資料進去，可以用 memcpy 將物件、字串或任何東西拷貝進去。我們也可以直接將 void * 轉型成物件指標，這樣就建立 shared object，不同 process 可以直接對 process 存取物件。

菜鳥工程師與資深工程師的差別是甚麼？
Continue reading其實我認為我大學期間，除了課業失敗的一蹋糊塗之外，其他方面還算優秀。不得不稱讚台大是一個很棒的舞台，讓我的立足點更高，使我有機會跟各式各樣的人接觸，參加各種有趣的活動，到不同的地方工作。在這環境下，我覺得過得還算是順遂。即便如此，仍有些事件是難以忘懷的失敗，給我很大的教訓和反省，但其中一個最難忘的故事莫過於我接下來要說的。

Chaos implies a disorder or complex non-linear system. It manifests any little changes could probably result in a massive transformation of the system, such as a butterfly flapping in Brazil could cause a hurricane in Texas, which is well known as the butterfly effect. The traits of chaos are in many fields, including math, physics, atmospheric science, fluid dynamics, ect., which leads Chaos to a vital research topic.
