Here I’d like to share some of recent updates of mine. Changes After a year’s endeavor on intelligent database auto-tuning system, to which I’ve devoted all myself since March last year, I’ve grown to be a Mr-know-sth on MySQL database, known each other’s advantages and disadvantages in the team, learned the absolute importance of self-motivation, became a fullstack engineer, and by the way, might possibly get promoted. I met xiaoya, through friends.

I was about to write something on Procrastination, but it’s such a huge topic for me to make it clear and solvable. What is it? Pro-Cra-Sti-Nation procrastination is avoiding doing someting. it’s not being able to get started. it’s trying to avoid the inevitable. it’s over complicating things yourself. it’s being afraid of finishing something. some not knowning when, some not knowning how to finish someting. How about this, I’ll share some things that are intentionally or unintentionally delayed by myself, at last they got finished and I could not be more happy about that.

The algorithm Flood fill is an algorithm that determines the area connected to a given node in a multi-dimensional array. It is used in MS-Paint program as the “bucket” fill tool to fill connected, same-colored areas with one new color, and in games such as Go and Minesweeper for determining which pieces are cleared.

About a month ago, I graduated with a M.S. degree from Chengdu, and now end in Alibaba which is one of the biggest internet company in China. Graduations are both painful and joyful, but for me they are more like thrilling. The eager to explore something new and the just proper fearness can excite everyone. Hanzhou is a beautiful tourist city as I heard about, and worth exploring whether it’s a good place to live.

In this QingMing Jie, one of Chinese traditional holidays, I clean and bag my old books, plan to sell them for a minimal charge. I posted a thread which expressed my desire on the campus forum and more than half of my old books had been sold in 4 hours. It goes so smoothly because of the books’ high value and their attractive price. But why do I bother to do this ?

Having been very busy working on graduation thesis since last month, I figured out that serious writing should be very important and of great priority in my work from now on. Why do I make such a decision? There are mainly three reasons. Serious writing helps me think clearly. If I want to convince others of my thoughts, I have to make them very clear to myself first, which helps training my mind.
