• Why do people say that Ruby is slow?

  - by stephen murdoch

  I like Ruby on Rails and I use it for all my web development projects. A few years ago there was a lot of talk about Rails being a memory hog and about how it didn't scale very well but these suggestions were put to bed by Gregg Pollack here.

  - by Stephen

Ruby 1.9.1 outright segfaults on Rails 3.0.0, so if you want to use Rails 3 with 1.9.x, jump on 1.9.2 trunk for smooth sailing.…

In emacs lisp, would you do something like (find-file 'out') (setq fout (current-buffer) (find-file 'in')…
