It is so much learning to go over the lectures again after 2 months. The lecture on pluralsight.com is three hours 10 minutes long. The first time study is documented, the blog link is here.
In order to practice those principles like TED principle, Julia has to write down and try to have some workout first. It is also good practice to go over some lecture note before taking another mocking interview in the weekend.
To be a better programmer, stay competitive, the mocking interview is the great opportunity for Julia to learn how to work on small things each time, learn to communicate with the peer to solve problem. More practice will help Julia learn and have some creative ways to solve the problem.

Go over the lecture video again
TED Principle (remember it, repeat three times! TED Principle, TED Principle, TED Principle)
Terse, expressive, do one thing
Don't repeat yourself
How to write Self-document code?
layers of abstraction
Assign Booleans Implicitly
if(age > 21) const int legalDrinkingAge = 21
if(age > legalDrinkingAge)
Encapsulate Complex Conditionals
Principle: Favor expressive code over comments (expressive vs comments, two choices, a principle?)
Be declarative if possible
Clean -> Use LINQ
.where(u => u.AccountBalance < minimuAccountBalance)
.where(u => u.Status == Status.Active);
Interesting? Call it "Be declarative if possible". It is hard to related to LINQ example.
Table Driven Methods
- great for dynamic logic
- avoids hard coding
- write less code - Avoids complex data structures
- Easily changeable without a code change/app deployment
