100,000 Yay!

I found my little site has reached a minor milestone, 100,000 views, over years! Yay!

Inspired by Dan’s famous blog PENGUINPUNK (https://www.penguinpunk.net/blog), I started to write technology blog years ago. Thanks Dan!  Since then, the intention of writing articles didn’t change – purely for sharing. Thanks for the internet, except reading and training, a large part of my IT knowledge and skills are built on IT professionals’ experience around the world. Starting to share my experience is the way to join the sharing team. I am proud to do so and believe someone could benefit from my sharing as I did from others’.

As a LAZY writer, I will continue to write. This is a minor achievement, but every step counts!

I am ready to cheer for 200,000 views soon!
