Hey WWW::Mechanize users, I''ve been using Mechanize for about 3 or 4 months now, and I''m rather enjoying it. I''ve done scraping in PHP & Python, starting with raw text and HTTP requests, moving up to regex and Curl, and finally landed myself here, making me much more productive when scraping pages. At the moment, I''m in the middle of a decent sized

I was going to add caching to my applications, but everything that I''ve found through google is about all of the problems everyone has had with caching. Is is really as bad as I''ve read? -- Posted via http://www.ruby-forum.com/.

Hey guys, As most of you know, Rails 3.1 introduces query caching for ActiveRecord. Great change all-in-all, but for those of us with IT department mandates for using MySQL (yeah, yeah, I know...), it''s kind of a mixed bag. I need to disable query caching in a project I''m building based on 3.1. I''ve tried a couple different approaches, both without any success. I

I''m about to get starting integrating Paypal Website Payments Pro, and I''m wondering if anyone has any tips or best-practices to share. So far I''ve found a few paypal related tools, of which the ELC Plugin (link below) seems the best suited for payments pro, but I''d love to hear any experiences verifying or contradicting that, or any war stories at all.

First of all, thanks to everyone who answers these questions - it's most helpful. I'm new to R and despite searching have not found an example of what I want to do (there are some good beginner's guides and a lot of complex plots, but I haven't found this).

Does anyone have any general tips on how to get programs to work on Wine? I hear lots of success stories for various programs which I have failed to get working on my own machine. But then again, my own version of wine is a bog-standard installation without any special adjustments made to it. What are the steps usually taken to attempt to get a program to run under Wine? Or is that too
