Hi, I‘m Dracula who is studing CS in hust. Now I’ m just like an idiot to IT, and just do well in C and python. When I was in my freshman year and sophmore year, I’ve attemped to research Software Defined Network(SDN) and its applications, simple part of machine learning and image recognition, distributed big data process system like Spark and Flink. I have also taken part in several competitions and attained serveral rewards. In a word, I have played many in recent two years. However, I’ feel sitll far from the core. Consequently, I build my blog to compel myself to accumulate and refine what I’ve learned.
