Excellent Ruby refactoring articles on rubyist magazine -- Also, does nyone know license of code on site?

The site http://jp.rubyist.net/magazine has an ongoing code analysis and
correction series. For example, issue 13 has a DBF file reader and writer
library that is analyzed
and made more ruby like. Here is the translation link that I used to read
the file:

http://bestiland.thread.ne.jp/nec/c3/ql.cgi/http%3A//jp.rubyist.net/magazine/%3F0013-CodeReview?SLANG=ja&TLANG=en&XTYPE=0&XPARAM=name,subject,msg,key&XCHARSET=x-euc-jp

Is there a way we could get this whole series translated to English by
someone fluent in Japanese and English? Also, what license does the code
referenced in the article fall under?

Thanks,

dominic
