There are a few styles for code reviewing, like just take a look around the code. Maybe something missing character or the naming variable does not fit our organization code standard such as using camelCase or Sentence case, or maybe to use CAPITALIZE string for constant.

But sometimes or perhaps it should happen when you do some code reviewing, do checkout branch to your local machine. To check the process on the Pull Request issue.

In this case, I use 3 level branches: upstream, origin, and local. Which is a pull request that happens on the upstream level.

Do you see so many job vacancies on the jobs portal? Do you ever think about it, why the position is not fulfilled yet? Even there are so many candidates out there. I’m not a recruiter or headhunter, but I just thinking about it. Why it happens. …

Part of [TIL] series on my medium page.

CAP principle :
Consistency : data consistency for each machine
Availability : system still works while one of the machine is down
Partition Tolerance : system still works while the machine not connected

You could only choose 2 of 3 in CAP theorem .

I would like to make this series of [TIL] as my knowledge base, so basically I will make this as my library. Maybe could be useful for you too.

Case :

Build a system (example : API for regional data) which can handle 1000 requests per second. On the second month requests increase to 10,000 per second, then third month increase to 100,000 per month.

Vertical Scaling :

Increase current server : make higher RAM, CPU, HDD.

Horizontal Scaling

Build new server with same specifications

Comparison between Vertical and Horizontal Scaling :

  1. Fault Tolerance
    VS : need downtime if something happens on server
    HS : no need to downtime, since another servers still works
  2. Low Latency
    HS : distributed area, will choose the nearest server. So it will reduce latency response time.
