在網路上似乎找不到中文網頁Lambda在Haskell上的用法, 所以寫了這篇稍微介紹一下
lambda function其實也就是anonymous function, 在Lisp, Python, C#3.0, VB中都有support類似的語法
\x -> x + x
"\" 念做 lambda
TBC...

http://ruby-mp3info.rubyforge.org/
I tried to install through gem remote repository like:
gem install ruby-mp3info -> not work
But I got error message:
ERROR: http://gems.rubyforge.org/ does not appear to be a repository
ERROR: could not find gem ruby-mp3info locally or in a repository
So I download the gem file manually from RubyForge site and install:
F:\cmplayer\library>gem install -l ruby-mp3info-0.6.13.gem
Successfully installed ruby-mp3info-0.6.13

Sometimes the connection is too slow, and sometimes I have to read doc offline. So I use the following command to mirror the whole web site to local drive.
wget -m http://ruby-gnome2.sourceforge.jp

I'm trying to install ruby-gtk binding on my iBook. That's Mac OS 10.4.11 with PowerPC based CPU. First of all, MacPorts is fucking slow! Sencond, MacPorts will not handle package dependency problems automatically. I have to install separate packages by myself. That's so sad...
Instruction to install ruby-gtk:
sudo port install rb-gnome... and take care a lot of dependency problems...

I got a book - Ruby by Example Concepts and Code.
Link is here:
http://www.amazon.com/Ruby-Example-Concepts-Kevin-Baird/dp/1593271484/ref=sr_1_1?ie=UTF8&s=books&qid=1231599489&sr=8-1
I want to read one chapter a day starting from today.
Why I want to learn Ruby?
No idea...
Maybe just a belief...

根本也沒用過這邊的blog, 也沒跟別人說過
竟然今天有四個人的人氣, 是哪裡有毛病阿 @@
都快忘了這個帳號了
只有一個人會知道它的意思, 如果還記得的話
哇 好久了 酷
正在看星光大道
下次看到這篇文章的時候, 這個節目還會活著嗎
曾佩慈"溫柔的慈悲" 開頭唱的不錯
