something

about my blog.I use google analytics to watch the visitors' locations of my blog,found that more and more alien people come to this site,I'm surprised.But at the same time,I decide to write more english posts.It seems like that since I write "all about my english",I haven't write any english in this blog,so you can see I'm a person without perseverance.Another thing is I plan to change a template tomorrow,I use google reader to subscribe some blogspots,maybe I'll add it to the new template.
about this afternoon's class-network security of computer.the teacher told us not to install operating system use a version called donghai ghost_XP 4.x and 5.x because there are some loopholes(is this word c.n or uc.n?).
a problem of my computer.I only install one OS on it,however,everytime the OS started,it'll break out a menu for choose OS(both XP),what's the reason?provide a clue,the format of C disk and D is different,one is NTFS,the other is FAT32.
