I''m seeing some unexpected and strange behaviour with respect to quotas and zones. Initially I set things up with no quota on the data set that as delegated to the zone. Then as the local zone admin I created a new child dataset and set a quota on that. Now the global zone admin attempts to quota the delegated dataset, and it appears to work but.... global zone=pingpong local

Hello! The current swfdec from git won't play videos on youtube. I had bisected the change. 8fc53e76 ("merge the too get_variable functions") is the last good revision. 89d295a94 ("implement swfdec_action_get_movie_by_path() and use it for GetVariable") is broken.

Hello, I was wondering where I might find more information about using OTP as an authentication protocol with dovecot. In searching, I found a thread from 2004, but not much information about how it has progressed from then. I also saw some promising patches from mid-last year, which if I had to guess are probably the addition of support for the SASL OTP mechanism. Is this available in a

I am trying to write a dynamic linked library for R, in Pascal. (This is to speed up the execution of a simulation that I am running in R.) I know Pascal might not be the perfect language for this (C or Fortran being more natural), but from what I have read I think it should work. Though I should point out that I am a neophyte when it comes to DLLs. From R I want to hand a function in

We''re encountering a failure with Mocha 0.5.6. We had this expectation: game_version.expects(:attributes=).with(:game_file => kind_of(GameFile), :game_id => @game.id) This expectation was passing with 0.5.5, but fails with 0.5.6. I added this test to parameter_matcher_acceptance_test.rb, which passes in 0.5.5 and fails in 0.5.6 def test_should_match_nested_parameters
