Today, I bought FIFA 2008 at EB Games with $30 off. It is really a good
deal, isn't it? However, after trial, I haven't experienced any
improvements over FIFA 2006 except the music...

I found a cool search engine - SearchMe
(a gold supporter of the conference) on the website of CIKM 2008. It
uses a totally different way to present the search results. Compared
with snippets, picture slides is much more intuitionistic and friendly
to users. Users can easily make an initial judgement whether the
contents of a web page can satisfy their requirements.
To be honest, the most interesting feature attracts me is the classification of the returned web pages. When we input the keywords, a classification is instantly shown on the top of the slide. This feature is very useful for effectively filtering out the irrelevant results. Of course, the accuracy of classification should be improved (I think it mainly depends on the research of web mining), but this is a good direction.

Yesterday, I got an invitation for EverNote Beta. After the trial, I
understand why it is so popular. I can manage my large amount of
research papers with it in the future. As long as the computer and
Internet is available, I can find any notes or papers I want. But PDF
full-text search has not been supported in Windows version yet
(available in Mac version). This function is very attractive to me
because most papers are in PDF format.
Anyway, with this useful tool, I can take notes anywhere even though the computer or Internet is not available. Write something on a paper, take a photo with my phone camera, upload to my computer, use the OCR function to recognize what is written, then I can search any texts although they are on a picture. Very convenient, isn't it?

For sure, Dapper can help our web
sites convey semantic information or meta data and make our web sites
more structured. But I doubt whether it can help the search engine
improve the accuracy or precision of the results of a keyword search.
Have a look at the keyword search over relational database or XML
database. The data is structured, but the results of a keyword search
is not ideal. Therefore, the precision of results is not determined by
whether a web site is semantified. Semantifying is just the first step.
Users express their intention through several keywords, but these keywords convey too limited semantics, so it is very difficult to find out what information is really wanted by the users. If this problem can not be properly solved, the semantic information conveyed by the web sites may be not very helpful. Therefore, when our web sites become semantified, we also need a new simple query pattern to make the keywords more semantic.

I just signed up a VPS plan from Linode.
It is called Linode 360, which provides 360M memory, 10G storage, 200G
transfer per month, and more importantly, an affordable price. Please
remember, if you are in Australia, choose the data center at Fremont CA
because it can give a decent ping value around 192 ms, which is better
than most hosting companies in America. I plan to move my previous blog
to this VPS server, but some necessary environments need to be built up
first. This article is mainly about how to setup Lighttpd, MySQL, PHP,
and Perl on Ubuntu 8.04 LTS. They are necessary for Wordpress or
Movable Type blogging systems.
Step 1: Create a new user in Ubuntu 8.04, with sudo privilege.
After Ubuntu 8.04 is deployed, we should create a new user with sudo privilege to perform most common tasks. If you have created one, you can ignore this step.
Step 2: Update the system and Install the basic tools.

> adduser xxxEdit the sudoer's file:
> visudoAdd "xxx ALL = (ALL) ALL" at the end of the file. Then re-login the system with xxx.
Step 2: Update the system and Install the basic tools.
> sudo aptitude update -yStep 3: Install Lighttpd, MySQL, PHP
/> sudo locale-gen en_GB.UTF-8
/> sudo /usr/sbin/update-locale LANG=en_GB.UTF-8
/> sudo aptitude install build-essential -y
> sudo aptitude install lighttpdStep 4: Configure php.ini and lighttpd.conf
/> sudo aptitude install mysql-server
/> sudo aptitude install php5-cli php5-cgi php5-mysql php5-xcache
> sudo vim /etc/php5/cgi/php.iniAdd "cgi.fix_pathinfo=1" at the end of file php.ini.
>sudo vim /etc/lighttpd/lighttpd.confFind the codes like below and add "mod_fastcig" and "mod_cgi" modules:
server.modules = (Add the following codes at the end of lighttpd.conf:
"mod_access",
"mod_alias",
"mod_accesslog",
"mod_fastcgi",
"mod_rewrite",
"mod_cgi",
)
fastcgi.server = (".php" => ((Step 5: Restart Lighttpd
"bin-path" => "/usr/bin/php5-cgi",
"socket" => "/tmp/php.socket"
)))
cgi.assign = (
".pl" => "/usr/bin/perl",
".cgi" => "/usr/bin/perl"
)
>/etc/init.d/lighttpd restartAfter the steps above, the necessary environments have been built up. It is enough to install Wordpress or Movable Type.
昨天晚上突然接到老妈的电话，说是地震了，房子不停的摇晃，于是她就在浴室里待了许久，当时还以为就再也见不到我了。今天早晨给家里打电话，昨晚又震了两次，老爸老妈在车上待了一夜。刚才在网易看到一张照片，一所学校的操场上摆满了师生的尸体，让人心里真不是滋味。
想想自己也应该为灾区人民做点什么，于是我通过paypal向中国红十字会李连杰壹基金捐赠了100美金，虽然数额微不足道，但也算表达了自己一点点心意。希望08年不要再发生什么灾难了。

Phil had just joined a club after his friend had recommended it (being a member for quite some time).
They were sitting at the bar having their beers when someone yelled "21" and there was a small uproar of laughter. A few minutes later someone else yelled "34" and another roar of laughter rose up. Phil, confused about this asked his friend "Why is everyone laughing at the numbers being called out" His friend said, well we've been telling the same jokes for so many years that we just numbered them all and if you want to tell a joke you just call out a number"
Phil nodded and said "Can I try?" His friend nodded and Phil called out "121" and everyone in the club roared with laughter and it didn't die down for at least another 15 minutes after. "Why did everyone laugh so hard at that joke?" Phil asked. His friend said with a small chuckle "We haven't heard that one before."

今天早晨起来登录Bluehost，发现又升级了，好几个unlimitied。真的很想知道那些用到几百G空间的网站是怎么用的。
Bad:
1. The problem of frequently loading/unloading hard drive on a laptop continues to exist in Ubuntu 8.04.
2. The evolution-data-server process randomly consumes CPU up to 100%, even though it is in sleeping state.
3. Sometimes, when I click the calendar at the top-right corner, the whole system stops responding.
4. The speaker makes a sound, but the earphone doesn't.
5. (Update) If the machine returns from Suspend state, the problem of loading/unloading hard drive appears again.
Good:
1. The interface is awesome, especially after compiz is installed.
2. Substitutes can be found to replace the popular softwares under Windows. More importantly, they are free.
3. I found a good tool, Nemiver Debugger, to help me debug C/C++ programs. Even though it is not as powerful as Visual C++, the basic functions are provided.
4. I don't need to worry about the annoying virus and spywares in the future.
