Right now I''ve just got: @new_tutorial =

What is the ideal server setup in terms of RAM vs. Processor Speed (more RAM or more processor speed?) and should I use Apace, lighttpd, mongrel, or what?

As Timo seems to be on a committing spree; I'd like to propose that in the mail_log_fields the recipient would be available. Like probably many dovecot users, my MUAs save to Sent; so when grepping the log to learn etc. that would just be useful Kind regards -- peter

Heyo! I am setting up a self-referencial habtm relationship with the users of my app. I am using Chad Fowler''s "Rails Recipes" to get me started, and everything works great with the join table "people_friends". I add friends by doing somebody.friends << somebodyelse. However, with my app, there is an approval process so my join table has columns person_id,

My girlfriend and I have been dating for two years, and she just told me she has an STI... Actually, I currently have three different models, like: Dog, Whale, Monkey They all have some similar attributes, but, they are unique enough to break into their own models. I could use STI, but I think the table would just have too many columns. Now, I wanted to let the Dog''s, Whale''s

Hello Everyone - Newbie here. My programming experience is primarily SQL, SAS (if anyone knows that), and a little tiny bit of ASP. Want to get going on Rails. Any suggestions? Was thinking of "4 Days on Rails". Thoughts? Thanks - Brian

I have the rails recipes book and i was going through the migrations recipe. Everything seemed to work except for the last part in trying to do a rake migrate with a migration file version 1 and the schema_info version set to 0. Without the force attribute, the rake migration fails, as expected. So the recipe says to run this: ruby script/runner

Just in case some of you missed it, Pragmatic Programmers just published their first of a series of short, PDF-only books. This one is on qtRuby. It would be great to have something like this for wxRuby. I don''t think wxRuby is quite ready to this (yet), but I thought I''d plant the idea.

I wish to second this approach to learning R. I tried for several years to translate other stat programs or provide parallel analyses with R. This dabbling-in-R approach did not work .

Yesterday I got the beta version of ROR recipes book and the recipes are great. For those of you still thinking about it, I highly recommend the book. The only thing I wish is that if there were some more recipes (greedy me), especially AJAX related and installing an application within your current application. For instance, it will be great to see how one can implement the typo blog
