Quick links post: Gregory Brown is looking for comments and donations for a [proposal for a Ruby Mendicant University](http://blog.rubybestpractices.com/posts/gregory/025-ruby-mendicant-university.html), basically a rolling online Ruby course. Charles Nutter is interviewed by InfoQ on [the state of JRuby](http://www.infoq.com/articles/state-of-jruby). Yehuda Katz has a long post on [various kinds of extensions in Rails 3](http://www.railsdispatch.com/posts/how-rails-3-enables-more-choices-part-1)...

### iPad Note I keep wanting to write about the iPad, but so, so many other people are writing about it that I'm not sure I have anything to add. More or less at random, I really liked the brief rant Joe Posnanski added in the middle of an [otherwise-unrelated...

### Top Story I'll mention somebody else's book, but don't worry, I plan on doing it in a totally self-absorbed kind of way. Pragmatic released [Using JRuby](http://pragprog.com/titles/jruby/using-jruby) into beta yesterday, by the core JRuby team. Looks good, interested to see where they go with it.
