I've been a C/C++ and VB developer for many years. Time changed and we have to do with colossal data in our business. I found I am so interested in data analysis work. I picked a couple on-line courses and did some self taught. I included exercise code here for my review later.

• Node.JS & JavaScript
• Python
• Octave
• R
• C/C++
• Java

Since Auguest 2015, I've been planning some IoT & Cloud product. I got involved in Androidd, Arduino and BigData technology. Also put in the lab code.

• Android
• Arduino
• CloudAPP & CloudComputing

The courses I took include:

• Machine Learning [by Andrew Ng from Stanford]
• Practical Machine Learning Series [by Jeff Leek, PhD, Roger D. Peng, PhD, Brian Caffo, PhD from Johns Hopkins]
• Cloud Computing [by Indranil Gupta from Illinois]
• Cloud Computing Applications [by Roy H. Campbell, Reza Farivar, PhD]
• Programming for Everybody (Python) [by Charles Severance from Michigan]
