E本係怪咖心理學嘅第三集，雖然有D theory己經係第一集講過，但依然相當有趣。
今次主要係講科學嘅角度講超自然現象。比較surprise嘅係，原來某D「科學」嘅解釋都唔係正確嘅解答。
像外行一樣思考 像專家一樣實踐
E本書共有四章，主要講作者嘅一D唔同嘅想法。書名「像外行一樣思考，像專家一樣實踐」只係第一章嘅內容。本書得四份一個內容係我嘅expectation之內，餘下嘅三章，其中兩章相當精楚，值得一讀。
由於作者係一個居美日籍computer science嘅教授，有D想法同例子令我覺得特別親切，亦都係我鐘意E本書嘅原因。
文中提到「類比電腦」，係利用自然法則去計覺問題嘅答案，係一種幾有趣嘅解決問題嘅方法

What are the main uses of Command design pattern?
Command pattern 有時好似有D dummy，無端端要decouple generate request 同 execute request 嘅object。但係現實中有以下場境：
- GUI
- 因為UI(request generate object)，成日要轉，所以最好拆開，亦姐係MVC pattern
- Marco recording
- 因為要record同replay行過嘅步驟，decouple左之後，只需要儲低個request object就做到
- Multi-step undo
- Similar to Marco recording
- Networking
- Remote execute嘅情況，request generate object 同 execute object唔係同一部機上邊，焗住要decouple
- Progress bar
- Decouple左個execution做一個個step之後，我地track住個request object，就可以知道個progress
- Transaction
- Similar to multi-step undo

Why vendors perform code diagnostics before taking over an app developed by a third party
2 steps before taking over the code base
- Codebase review
- is it complete (and matches the deployed version)
- does it have clear commit messages
- is it easy to setup the environment
- Exploratory test
- find out bugs in the existing product
- understand what needs to be fixed, or what bugs existed prior to any new development work

Good to know how vendor take over an unknown code base.
