Geoff writes about our cached_model and memcache-client libraries: The Robot Co-Op has made a few libraries available. cached_model makes it easy to cache single row queries from ActiveRecord tables. memcache-client is a pure Ruby client and is included with the installation of cached_model. —memcached Basics for Rails via Nuby on Rails...

You may have noticed me using both $stdout and STDOUT in my last post and been puzzled by how I could use both. When Ruby starts up the process’ standard output file descriptor is stored in both the constant STDOUT and the global variable $stdout. STDOUT holds the process’ original stdout while $stdout is reassignable. Kernel#puts...

cdfh on #ruby-lang asked how to redirect $stdout per-thread and I came up with this solution, redirect via a thread-local variable: ## # Allows $stdout to be set via Thread.current[:stdout] per thread. module ThreadOut ## # Writes to Thread.current[:stdout] instead of STDOUT if the thread local is # set. def self.write(stuff) if...

We consume flickr photos as part of 43 Places and use their tags to automatically add them to places. One new user creepily found his own face as his hometown’s featured photo.

With many thanks to Hugh Sasse for doing much of the gruntwork, there will be a huge increase in RDoc available in Ruby 1.8.5. If you have the time, get the latest from CVS (HEAD or ruby_1_8) and make install install-doc, check it out, and report back anything busted, poorly worded, or in need of general cleanup. I have until Sunday night to...

For Trackmap I need to take the time a picture was taken and a user supplied time zone and convert that to a correctly offset time. Since Flickr won’t give me a time zone (cameras don’t record them) I ask the user. If they say Mountain time I need to create a time that is correct for the server’s clock (in my case Pacific...
