2, PriorityQueue不保证先进先出（如果要保证先进先出，可以用AtomicLong给元素编码，然后再compareTo方法中判断）

3, TreeSet中判断是否是同一个元素是根据compareTo方法，而不是equals方法！与Set的约定有违背。

4, TreeSet的Iterator升序。

My plugins are hosted in wordpress.org. They prefer SVN to manager these small projects. So I spent a little time on SVN to upgrade my plugins. Here is some notes:

Take on of my small project for example: the repo of plugin automatic-tag-link is http://svn.wp-plugins.org/automatic-tag-link/

FIrst, create a folder as a local SVN repo.

mkdir automatic-tag

then, restore the files from remote SVN repo.

svn co http://svn.wp-plugins.org/automatic-tag-link  automatic-tag

so, we can modify the files, when finish, we should commit it to the SVN server.

svn ci -m “some messages”

if we add some new files(eg, newfiles.php), before commiting, we should add it to the repo.

svn add newfiles.php

I just read Chapter 5, something about program veritfication. It’s an old topic, but important for a starter.

I just told to my teacher about the schedule of graduate staff. I’ll leave Tianjin Univeristy in June.

Six years in Tianjin, and I’ll say beybey to this soon. BeyBey, all the pains, all the happiness, I’ll never come back.

Days ago,  my roommate ask me some questions about owl,ontology,  and I could hardly answered them perfectly.  I spent most of  my time on job hurting, writing codes, and surfing the net recently. I’m not a qualified semantic web student.

I remember I filled the Research Area on the new student form with “service computing” just because I work on a big project about Web Service in the lab. Actually,  I didn’t really know what the hell is “service computing”, and I thought I’ll still foucs on Semantic Web in my research life, which proved wrong. It’s a little ridigous of the whole thing.

“Day day up” is kind of spirit, a positive way of living. Tell yourself to improve when you get up and ask yourself what’s the achivement today when you go to bed. If you need to learn something difficult, that’s useful.

All my research is fouce on Semantic Web, SOA, and I’m not familiar with data mining, NLP or such things. But the requirments of MSRA MLG are just about Semantic Web, so I think maybe I have chance to get it. But I failed in the end.

Why failed? I think about this sometimes. Bad phone communication skills? Bad Language(C++) skills? Misunderstanding the hiring manager’s words? None prepared?

I will take my second phone interview in some days. Now I should do some homework. I should prepare for every interview and never take naked again.

When I opened my rss reader this morning, and I found all my codes become a serial of meaningless numbers. That’s strange.  It not happened all the time. but still, that depressed me a little.

There are some rules for using softwares I made years ago, one of them is: “If not necessary, do not upgrade!”. I’m against my own rules, and I paid for that.

I hope next release will fix this.

I like the status bar very much. I will only appear when you need it (eg. put your mouse on a link, then the statur bar will appear, when your mouse goes away, it’s gone too).

Surely, there are something not so good, especially the memory it eats.  I opened 5 tabs, and nearly 100M memory is gone.Waiting for the next release. :)
