I am having a problem with two models that each have a HABTM relationship to the other. For example: CREATE TABLE people (id INT, name TEXT); CREATE TABLE teams (id INT, name TEXT); CREATE TABLE people_teams (person_id INT, team_id INT); The person model has: has_and_belongs_to_many :teams And the team model has: has_and_belongs_to_many :people The trouble comes when trying to destroy

I would like to be able to allow regular users that don't have admin privileges to be able to reboot their workstation. (they're software developers so rebooting their workstation doesn't affect anybody else) I tried changing the ownership of /sbin/reboot and /sbin/shutdown to root:users and permissions to 550, but that didn't work - it's still asking for root privileges.

Dear R users, I am using the Sweave package and I am doing some MCMC. I have a loop function for my MCMC. Every 100 iterations, I want the number of iterations already done to appear on my screen (but not on the final document). Is that possible ? Usually I can rely on > if (i%%100==0) cat(i, "\n") but not when using Sweave. Thanks for your help, Jimmy [[alternative HTML

Dear R users, After running Sweave, this is what I get : Warning messages: 1: glm.fit: algorithm did not converge 2: glm.fit: algorithm did not converge There is no glm.fit function in my code. Where does it come from ? From Sweave ? From system.time ? Thanks for your help, Jimmy [[alternative HTML version deleted]]
