I want to use YAJL to render JSON. If I require 'yajl' in the controller and perform a render :json => some_hash, will this use YAJL to encode the hash into json? Should I convert the hash to JSON using YAJL's encode method before calling render? If not, how can I go about doing this? ...
I wonder, why don't they implement other languages like python and ruby on the web browsers? Don't they fit as client programming languages or did it just happen to be that Javascript was the first one to be implemented, and they then kept on only supporting javascript because it just worked. I mean...I really hate Javascript compared ...

Amazon guys had decided that xml-simple wasn't cool enough, so they supplied a replacement: 'faster-xml-simple'. And they also decided that everybody wants to use their code now, so they did ...

I discovered this while using ruby printf, but it also applies to C's printf. If you include ANSI colour escape codes in an output string, it messes up the alignment. Ruby: ruby-1.9.2-head > printf "%20s\n%20s\n", "\033[32mGreen\033[0m", "Green" Green # 6 spaces to the left of this one Green # correctly ...
I feel like I have a simple desire that no one can satisfy: I want to be able to graph a set of points, and I am using Ruby 1.9.2. I would like to use Gruff or Scruffy, since these seem to be the easiest to use. However, they both rely on rmagick, and it seems that many other libraries do to.
