I’ve been playing a lot lately with RoR (Ruby on Rails) and of course I love DIGG, hence I was very pleased to stumble upon a very interesting work by Patrick Lenz, which is a definitely cool and enjoyable free book (pdf) on how to build a full blown DIGG in Ruby on Rails from scratch!
I spent a couple of hours reading and trying, and I am already (!) building the app (or should I say building the DIGG) at this point of writing this post. The book uses Web 2.0 approach which covers a lot of Web 2.0 along the way – very cool! I highly recommend it to anybody who has the same passion, since it really is an awesome read!
Please hurry, as this book is only free (since the moment of me writing this) for "32 days, 14 hours, 21 minutes, 49 seconds" more, and I guess will blend in with many other books that we have to pay for once the time is up (currently it is $26.37 at Amazon).
For something "not very free", but "the best" on Ruby on Rails, there is another great book "Agile Web Development with Rails, 2nd Edition" that can be obtained, well, same place all other "not very free" books are obtained 
here.
It is not in any way an intentional advertisement for any of the links above, I am just so exited reading it, that I could not stop my self from sharing with the rest of the universe! 
hey man, I got this book, it’s indeed very awesome, I am with you!
Hello,
I have developed PHP sites before. Still do not get this hype about RoR, and in addition:
“Why would you re-build DIGG from scratch!?” This is just silly. Can’t you build something useful?
Downloading as we speak
will post my thoughts on it later on… Thx
Agile Web Development with Rails was very good.
Does this book cover summ that is not in RoR bible?
Thx
you got me going
DIGG is a very wise choice for a sample app to try out
very nice, will see if I can read it all, I really hope I will. Thank you thank you
wonder how digg on rails will perform
although they say rails is scalable, I have not seen a very busy rails site… YET
@Jimmy
Twitter is a large scale RoR implementation. It has had performance issues.
Here is an article and an at length discussion about it.

Looks like I missed the free window. I would be interested to see his approach. Is there any way you might be able to send me the PDF?
Great topics!
How can i find more ROR articles…
@Rajesh,
Check this one out: http://www.digitalmediaminute.com/article/1816/top-ruby-on-rails-tutorials
Also there is a good tutorial by “Kevin Skoglund”: http://movielibrary.lynda.com/html/modPage.asp?ID=324 – you can either pay/donate, or just torrent it out from several trackers. ( sorry Kev, but it’s a free option that is out there
)
Let me know if you need anything else,
– Toly
