Ever tried calling a win32ole (COM) object from Ruby’s DRb?
+1 Vote Up -2Vote Down


Before we get started here, let me state that I am using Ruby 1.9.1 (I refuse to look back!), and that I have not tested this solution on Ruby 1.8.6, but it should work there as well, though I may have some 1.9-isms in my code. Should be easy enough to spot.

I am working on writing an application in Ruby that can talk to an Windows application that has an ActiveX COM Automation object exposed. Ruby is basically the wrapper so that I can access the application from the Linux side of the world. So, I am using Ruby’s DRb to bridge those worlds because, after all, I am the Linux Bloke!

Well, as you may have guessed, I ran into problems with this …

DbCharmer – Rails Can Scale!
+0 Vote Up -1Vote Down

Back in November 2009 I was working on a project to port Scribd.com code base to Rails 2.2 and noticed that some old plugins we were using in 2.1 were abandoned by their authors. Some of them were just removed from the code base, but one needed a replacement – that was an old plugin called acts_as_readonlyable that helped us to distribute our queries among a cluster of MySQL slaves. There were some alternatives but we didn’t like them for one or another reasons so we’ve decided to go with creating our own ActiveRecord plugin, that would help us scale our databases out. That’s the story behind the …

Reusing models outside of Rails
Employee +0 Vote Up -0Vote Down

If you have done a good job of building your rails models, you may find that they are helpful for your non-rails system maintenance and such. They may even be necessary to reuse if you follow the rails model of using activerecord validations (rather that database RI) to preserve the integrity of your data.


Or you may just find yourself rewriting the same code again and again, and want all that good railsiness to make it easier to write and maintain. Personally I find myself in some instance of ./script/console as often as irb just so I can get the activesupport helper methods ( 4.days.from_now and such) that many rails developers …
