Value, Trend, and Another World

Never thought I could capture this scenery like I was in Bahamas. The color of this moment was exactly the same as one seen in Bahamas. Sometimes we recover our exhausted lives just by watching a moment of our memories.

Interesting. This interactive course demands detailed manual coding(typing) and also focuses on important points of Python coding with considerate video lessons. I'll continue to complete these courses. These programs inspire me, and show me some other insights.

Do you know that Microsoft supports DataCamp Learning for 2 month free subscription? Recently, I found this program. ( See More ) As a shareholder, I wanted to analyze detailed policies of Microsoft company ( MSFT ) . Anyway, DataCamp is one of on-line education sites, such as Coursera, and it is clearly optimized for learning R and Python. It gives you Interactive User Interface for easy learning R / Python. Several years ago, I used Python for a while to calculate a bunch of data, and thought this language was simple but cannot be alternative choice because of R. Python has adopted so many "imports" as simple/powerful libraries. Now, it's very easy to use, and efficient in analyzing huge data on and off the Internet. If you want to learn R or Python, I recommend you to register Free Microsoft Account for Free subscription on DataCamp for 2 months.
