As you might know. I am working for Samsung as a system engineer for 20 years. I really love new technologies such as IoT, autonomouse and android. So I need a lot of information about new technology. I like to google so much everyday. A month ago, I intended to make a presentation about IoT and I could find both nice report and pretty good pictures from some blogs. I've finished my own presentation successfully. I got a lot of help on the blogs. Later, I started a new project and I've learned new knowledge. So I posted my knowledge about ORACLE DB on my own blog. Some guests visited my own blog. I feel very proud of myself.
