I was too lazy to post a new article on this website. Once I skip a posting, it makes my lazy. Since August, I have been in the academic trip season, and it becomes difficult for me to make articles for the website. While I am writing papers, it is easy for me to write an article for the website because I am stuck in writing my own papers.
