It is hard to say that no update has been added since 2015.
There is a hard time since 2015, life come true, and need a lots of time on learning something new, discreate and deep. For now, I will try my best to log everything that I have learn, build and experience in computer and electronics. This is for my learning logs, but anybody is welcome to share if the info in this site useable to you.
Hope that I can manage time more efficiently and can update this blog/log frequently.
