Thanks, Aaron! We’ve used your technique to efficiently parse data from Elastic Search.

Got an issue today with ‘psyche’ and get rid of it on my production server …
On my local computer ( Mac OSX 10.6.6) psyche was not there and I use the I18n rails module
without any problem… ( ruby 1.9.2-p136 / Rails 3.0.3 )
I installed a remote production server ( Centos 5) with the same configuration ( but obviously not the same distribution) and running my app raised a YAML parsing error of my locale files

The parsing error message just mentioned a line # and a column #, but hard to find as the I18N module joined all the locale .yml files before parsing in a tmp file !
So, running in console mode, I found that the parsing error originated from ‘psyche’… getting rid of it, forced the parsing with ‘syck’ and now the app is running fine ….

FYI , Rails 3 + Ruby 1.9.2 + Centos 5 => need to hack it

Thoroughly enjoy the flippant style, as well.

Flippant, because _why was flippant. Sadpanda.

I never had success installing psych as a gem… I have been using Ruby 1.9.2-p0 ever since it came out, so that is not the problem. Could you please make it available on rubygems as a gem Thanks!

Hey Mark! Ya, I usually write method definitions with no parenthesis. I guess I’m just used to it that way now. It used to surprise me when there were no parenthesis on method definitions, but I’ve grown to like it.

I’m glad you enjoyed the post! Thank you!

I’m starting to see more and more method definitions only enclosing the parameters in parentheses when there are more than one. You did it above (eg. “def listen listener”).

I’m not sure if its to cut down on keystrokes, but it does take me a quick moment to process. Beyond that I loved the socket code… we don’t see enough “low” level ruby stuff around anymore.
