• Something like PPerl for Ruby?

  - by sal

  I've used PPerl for deamon like processes. This program turns ordinary perl scripts into long running daemons, making subsequent executions extremely fast. It forks several processes for each script, allowing many proceses to call the script at once. Does anyone know of something like this for ruby? Right now I am planing on using a wrapper around curl to call a REST WebService written in Sinatra running on JRuby. I'm hoping there is a simpler option.

• Exception handling - what happens after it leaves catch

  - by Tony

  So imagine you've got an exception you're catching and then in the catch you write to a log file that some exception occurred. Then you want your program to continue, so you have to make sure that certain invariants are still in a a good state. However what actually occurs in the system after the exception was "handled" by a catch? The stack has been unwound at that point so how does it get to restore it's state?

  The problem: Given a set of hand categorized strings (or a set of ordered vectors of strings) generate a decision function to categorize more input. The question: are there any tools out there that will do that? I'm thinking of some kind of reasonably polished, download, install and go kind of things, as opposed to to some library or a brittle academic program.
