Bao's drafts

Mặc dù vậy, hầu hết tài sản của Zuckerbeg đều chỉ đang tồn tại trên giấy. Giống như cơn sốt dot-com xì hơi những năm 2000 từng minh chứng, cổ phiếu có thể trở thành giấy vụn trong chớp mắt nếu như giá trị thị trường của công ty lao dốc.

Common Code Smells

• Duplicated code: identical or very similar code exists in more than one location.
• Long method: a method, function, or procedure that has grown too large.
• Large class: a class that has grown too large. See God object.
• Too many parameters: a long list of parameters in a procedure or function make readability and code quality worse.
• Feature envy: a class that uses methods of another class excessively.
• Inappropriate intimacy: a class that has dependencies on implementation details of another class.
• Refused bequest: a class that overrides a method of a base class in such a way that the contract of the base class is not honored by the derived class. See Liskov substitution principle.
• Lazy class / Freeloader: a class that does too little.
• Contrived complexity: forced usage of overly complicated design patterns where simpler design would suffice.
• Excessively long identifiers: in particular, the use of naming conventions to provide disambiguation that should be implicit in the software architecture.
• Excessively short identifiers: the name of a variable should reflect its function unless it’s obvious.
• Excessive use of literals: these should be coded as named constants, to improve readability and to avoid programming errors. Additionally, literals can and should be externalized into resource files/scripts where possible, to facilitate localization of software if it is intended to be deployed in different regions.
