data editor in R- could it be improved?
...nce the names might often be very big if the data frame was created using a function). Side-ways scrolling is quite "jerky" too. Just wondered if this was on anyone else's wish list? Simon.

Interpretation of residual variance components and scale parameters in GLMMs
...QL(successes~1, random =(~1|status/maleID),family = poisson, data = d). Does that mean that the residual variance is actually 1.010882^2? Or should it be interpreted as a scale parameter, as in lmer? Thanks for any insight you can offer! Emily DuVal Postdoctoral Fellow, Max Planck Institute for Ornithology

Theoretical Firewall Specs?
...nd add more as needed, but where does one start out? How do I know if my firewall would need more RAM? How do I know if the CPU is good enough? I still go back to my Cisco PIX days where these devices were amazing on just 256MB of RAM. We piloted a large chunk of Cornell University's Lab Of Ornithology on 2 of these, but now-a-days it seems that a PIX would not be good enough. Is it because the nature of the internet and data and attacks has changed over time? more aggressive? -Jason
