Notes of Introduction to Algorithm(B-Tree)

When I was a college student and took the course Data Structure and Algorithm, the B-Tree section was not included in the exam requirement. At that time the teacher just said little about it and therefore I knew little about it. It is ridiculous that I totally understand B-Tree until last month. So what is the B-Tree? B-Trees are balanced search trees designed to work well on magnetic disks or other direct-access secondary storage devices. B-Trees are similar to red-black trees. but they are better at minimizing disk I/O operations. Many database systems use B-Trees, or variants of B-Trees, to store information.

An Analytics tool for Blogger

When I got the news that google has a website traffic analysis service Google Analytics, it’s too late for me to get the free service work on my blog. Because it has experienced extremely strong demand since google released this product and the sign-up has been closed alrealy. It’s so bad and I had to search for other tools to observe the traffic statistic of my Blog. Until now I have used 3 products: extremetracking, AXS and now Performancing Metrics.Although each of the 3 has both its and advantages and disadvantages, I prefer the last one, Performancing Metrics.

My Firefox Extensions

As in the previous entry “Goodbye Internet Explorer”, I strongly encouraged people to use Firefox for power surfing. By itself, Firefox is a lean and fast browser, and if you want it do more for you and remedy the situation that it lacks some of the functions that we’ve come to take for granted from Microsoft Internet Explorer, the add-on extensions maybe the best choice. They can do loads of tasks, from blocking pop-up ads to see the weather forecast—and even viewing a Web page as if it were in IE.

Goodbye Internet Explorer

For years I’ve stick on my IE (Microsoft’s Internet Explorer) since I had my own personal computer. But my love for the past faded when I met Firefox. Thanks to my mentor Daniel who introduced Emacs and also Mozilla Firefox to me. But, I guess most of my friends and many people in China are still using IE or other IE core browsers such as Maxthon. But today I want to tell you that it’s time to say goodbye to IE because a much better browser is ready for you.

Notes of Introduction to Algorithm(Red-Black Tree)

A red-black tree is a binary search tree with one extra bit of storage per node: its color, which can be either RED or BLACK.
A binary search tree is a red-black tree if it satisfies the following red-black properties:
1. Every node is either red or black.
2. The root is black.
3. Every leaf (NIL) is black.
4. If a node is red, then both its children are black.
5. For each node, all paths from the node to descendant leaves contain the same number of black nodes.

Basename Bug in MovableType 3.2

Recently, I encounter a problem when I use the “preview” function when I publish my entries. I guess you may have suffered this bug with MovableType 3.2 if you are also a newbie of MovableType. The problem is when an entry is saved from the Preview screen; the entry basename may be incremented or, if the title was changed, altered to fit the new title. And the other pages such as category page and index page will automatically change to the new entry’s permanent link.

My MovableType Archive Template

The original archive template in MovableType 3.2 will list all the articles in block. Of course, I do not like showing my articles in such a chaos. Obviously, My Readers will suffer a lot as the total of my articles increase to a considerable number. So I search the Internet and try to find a way that displaying the articles more friendly. Well I find a yearly archives template is very similar to my demand, but what I prefer is list my articles all together separated by month not year.
