This is on a Solaris 10 server. If I run the script as the 'apps' user (the system user that runs our automated scripts), the script runs fines....

Is it possible to send nothing to an object? Let me elaborate. For instance I could have something like this: val = some_stack.include?(some_val) ? some_val : nil obj1.obj2.send(val).obj3.obj4 The above call wont't work because nil is not a symbol. So the solution is: if val.nil? obj1.obj2.obj3.obj4 else obj1.obj2.send(val).ob...
Ruby 1.8 uses userspace threads, not operating system threads. This means that Ruby 1.8 can only utilize a single CPU core no matter how many Ruby threads you create.

Here's my wild and whacky psuedo-code. Anyone know how to make this real? Background: This dynamic content comes from a ckeditor. And a lot of folks paste Microsoft Word content in it. No worries, if I just call the attribute untouched it loads pretty. But the catch is that I want it to be just 125 characters abbreviated. When I add tr...
