- SQL

1 problem solved. 

 

- MeetCoder

I could learn about

1. Lazy evaluation

2. Docker nginx 

3. CS knowledges related with virtual memory.

 

It was very interesting because everyone in there explains so kindly and easily. I want to do some projects with knowledge of networks, DB, docker..etc. I always try to study the knowledge but have never used it.

 

There are some questions about cookie and session. I want to study more about that questions.

1. how could server know when session is out (user is logged out)? how does it remove sessionID..?

2. other differences about cookie and web storage 

 

- Algorithm

I tried to solve one problem but I could not spend enough time for it. Thesedays, it is so hard to think the plans for solving algorithm problem...  😂
