For example, if I have a number of member variables which I want to get or set, I don't want to have to create getters and setters for each attribute, since the code would largely be the same, just the variable I'm dealing with would be different. You've already gotten two useful responses. I'd just like to add that typically, the object attributes are referenced directly: rect.length * rect.width to compute area. Do not use: rect.get_length() * rect.get_width(). getter/setter methods get created when you some code is needed to control access: room.celsius room.fahrenheit computes the proper value from a single stored temperature (in Kelvin?). The code still looks like a direct reference to the attribute. You have a choice of using __getattr__/__getattribute__/__setattr__ or properties as suggested in the other email responses. -- Lloyd Kvam Venix Corp DLSLUG/GNHLUG library http://dlslug.org/library.html http://www.librarything.com/catalog/dlslug http://www.librarything.com/rsshtml/recent/dlslug http://www.librarything.com/rss/recent/dlslug ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

I think I'm going to tell myself that that's unreasonably paranoid--I hope I'm right :) A good GUI for traffic shaping controls would be a huge win. My basic philosophy on open AP's is that they can't make _my_ usage slow and they can't use enough data to put my connection over the ISP's monthly cap. I recently put a port-25 outbound block on due to some l0zer with an infected Windows machine that hopped onto my office network (I'm now in a mixed professional/residential neighborhood). The rate limits aren't too hard to do for those familiar with traffic shaper guts, but some user-land helpers would be really useful.

Re: Finding *unfiltered* free WiFi?
I confess that I'm happy to use free wireless on occasion but I worry that if I make my own AP similarly available then somebody is going to use it to post kiddy-porn or make threats and it'll be traced to my IP address and people with guns will then make me spend a lot of time money trying to convince them that I didn't do it. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/

They can classify traffic and assign relative priorities (good) but not hold anything to fixed caps or rates. I use the former on DD-WRT to keep my neighborhood network flowing nicely, but it's only fortune and cooperative neighbors that has kept our usage below caps (I'd really love to rate-limit limewire for one user). If 'unlimited' really meant that, the DD-WRT implementation would be perfect.

And the thing that is often forgotten is that the raid, seizure, and even jail happen *before* court-trial--before the issue of `defense' even enters into it. Ending up `not guilty' does not undo whatever damage is done by the investigative process. So, the question isn't so much `do you have a good defense' as `can you minimise your risk of becoming a suspect in the first place'. Though, if this sort of fear (`there's no legally-safe way to run WiFi') is really warranted in NH, then maybe we should raise an issue with our government; NH being home to the Free State Project, and having several Free Staters in the NH House of Representatives, it may actually be worthwhile to talk to them. -- Don't be afraid to ask (Lf.((Lx.xx) (Lr.f(rr. ___ gnhlug-discuss mailing list gnhlug-discuss@mail.gnhlug.org http://mail.gnhlug.org/mailman/listinfo/gnhlug-discuss/
