TaipeiLink Photo Grabber
This is my first Ruby script to fetch photos from TaipeiLink.
#!/usr/local/bin/ruby
require "net/http"
if ARGV.length == 0
puts "tplink.rb <account>"
exit
end
ARGV.delete("tplink.rb")
ARGV.each { |account|
puts "Fetching photos from #{account}..."
Dir.mkdir(account) if !FileTest.exist?(account)
Net::HTTP.start("photo.taipeilink.net", 80) { |http|
http.get("/#{account}").body.scan(/<a href="http://photo.taipeilink.net/#{account}?st=album&pg=(d*)"/) { |pg|
Dir.mkdir("#{account}/#{pg}") if !FileTest.exist?("#{account}/#{pg}")
http.get("/#{account}?st=album&pg=#{pg}").body.scan(/<a href="http://photo.taipeilink.net/#{account}/(d*-d*-d*-d*)?m=0&pg=(d*)"/) { |fileName, pg|
url = "/#{account}/#{fileName}?m=1&pg=#{pg}"
response = http.head(url)

PostgreSQL的cursor用法
PreparedStatement l_stmt = null;

PreparedStatement l_stmtClose = null;
ResultSet l_rset = null;

l_stmt = m_dbcon.prepareStatement("DECLARE FOO CURSOR FOR SELECT BAR FROM FOOBAR");
l_stmt.execute();
l_stmtFetch = m_dbcon.prepareStatement("FETCH FORWARD 10 FROM FOO");

安裝PostgreSQL 7.2
您可以從PostgreSQL網站下載最新的版本，目前是7.2版。下載後，建立一個叫postgres 的使用者，然後建立/usr/local/pgsql目錄，並將擁有者設為postgres，再將/usr/local/pgsql/bin加入postgres的PATH，再以postgres身分進行安裝。如果不要編譯JDBC driver的話可以不用--with-java，JDBC driver可以由jdbc.postgresql.org下載。
$ cd /tmp
$ tar xzf postgresql.7.2.tar.gz
$ cd /tmp/postgresql-7.2
$ ./configure --enable-locale --enable-multibyte --enable-nls --with-java
$ make all install
$ setenv PGDATA /usr/local/pgsql/data
$ setenv PGLIB /usr/local/pgsql/lib
$ setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
$ initdb
$ postmaster -i &
$ createdb -E UNICODE dbname
$ cd /tmp
$ tar xzf postgresql.7.2.tar.gz
$ cd /tmp/postgresql-7.2
$ ./configure --enable-locale --enable-multibyte --enable-nls --with-java
$ make all install
$ setenv PGDATA /usr/local/pgsql/data
$ setenv PGLIB /usr/local/pgsql/lib
$ setenv LD_LIBRARY_PATH /usr/local/pgsql/lib
$ initdb
$ postmaster -i &
$ createdb -E UNICODE dbname

PostgreSQL小筆記2
如果要同時用Big5、MS950、GB2312和Shift-JIS等charset，JSP、Servlet、EJB container的charset要設為 ISO-8859-1，資料庫的charset用SQL_ASCII，JDBC URL用 jdbc:postgresql://hostname/database?charSet=ISO-8859-1，如果不加charSet，PostgreSQL的JDBC driver會因資料庫的charset是SQL_ASCII而將client端的charset當成ASCII，這樣會把第8個bit去掉。

PostgreSQL小筆記1
啟動PostgreSQL前設定PGCLIENTENCIDING的話，PostgreSQL會先將資料轉換成PGCLIENTENCODING所指定的charset，再傳送給client端，同樣的，server會將client端送來的資料一律視為 PGCLIENTENCODING所指定的charset，在儲存前會轉換成資料庫所使用的charset。client端是用Java程式如JSP、Servlet、EJB且container是用Big5或MS950做為編碼格式(setenv LC_CTYPE zh_TW.Big5)，資料庫的編碼可以用UNICODE，在啟動PostgreSQL前不設定PGCLIENTENCODING，JDBC URL用jdbc:postgresql://hostname/database?charSet=UTF-8，這樣JDBC driver就會將資料以UTF-8格式送到server端，如果要用簡體中文，只要將container的設charset定為GB2312就可以了。
