Yehuda Katz's slides from SD.rb on Rails 3. I can't wait! Vaporware To Awesome from Yehuda Katz

I wish I could see this guy speak. I learn so much just reading his slides and other writings, I can't even imagine what I'd learn if I was actually there. Debugging Ruby from Aman Gupta

Found this in my internet travels, and found it interesting and informative. I hope you do too. Interface Design Basics (english) from Samo Korošec

tmm1 and joedamato put up a good slide show on slideshare about ruby threading issues, and their fixes. These things have been around for a while, but now they are here in slideshow form. Definitely check them out, even if you don't program ruby, as there are some interesting profiling/debugging shenanigans shown, among other things. Threaded Awesome from Aman Gupta
