Microservices

I would like to talk a little about microservices, and  i try to  step up by real life examples.

Think there is an obsessed mother with four children, she is taking care of all the following things herself,
and she has to serve the guest as well.

She is too obsessed with the routine and the workplace so and cannot change them.
It changes the whole layout when jobs need a change.

  • Child care
  • Laundry
  • Washing Dishes
  • Home Cleaning
  • Ironing
  • Guest hospitality

On the other side, there is another mother who doesn’t want to squeeze herself and wants to use her resources efficiently.

This mother’s;

  • The eldest child looks after the others
  • A child is washing clothes
  • A child washing dishes
  • A child cleans the house
  • The mother can both iron and serve to the guests



Using the Vi Editor

What is the Vi editor?

Vi is a Notepad-like tool for editing text files from the command line, widely used in the Linux/Unix community. Although it was often thought that Unix had been written by this tool, Vi was originally developed by Bill Joy in 1976. (Unix is based on the year 1969.) According to my personal experience, I can say that 50% of Linux/Unix use is Vi. The beginners have bad experience of editor usage and usually cool open source operating systems off when they are not comfortable to use. (The remaining 50% is the use of shell)
