Comments for mrz's noise http://blog.mozilla.com/mrz noise from a mozilla network engineer Thu, 08 May 2008 18:34:21 +0000 http://wordpress.org/?v=wordpress-mu-1.2.5 Comment on Al Gore by James Napolitano http://blog.mozilla.com/mrz/2008/04/11/al-gore/#comment-31173 James Napolitano Sat, 19 Apr 2008 20:51:40 +0000 http://blog.mozilla.com/mrz/2008/04/11/al-gore/#comment-31173 >What resonated most to me was his call to use information technology to “make the invisible visible.” I think there's a huge potential for improvement by applying this principle towards general energy use. Right now consumers usually think of their electrical outlets as a sort of unlimited fountain of electricity. If everyone had some sort of digital meter in their house in plain view (not like those ones in the back you never look at) that displayed how much electricity was in use and how much it was costing them (both in $/hr and their total bill so far), then people would be a lot more concious of turning their things off. The instant feedback they'd back would also provide info on how best to save electricity, e.g. which appliances use the most. Out of sight, out of mind. The meter could also display the amount of C02 they've caused to be emitted. Everyone blames the big energy companies, but the demand side of the equation is just as important as the supply. (note: they do already have a handy gadget called a Kill-A-Watt that plugs into an outlet and tells you how much power a given appliance is using up) >What resonated most to me was his call to use information technology to “make the invisible visible.”

Here Awstats correctly counts .at as Austria and .au as Australia. Could also be some strange routing from an Austrian provider. Strange.

If you goto http://www.maxmind.com/app/locate_ip and enter your source IP address, maxmind returns HK. When I built the static map I only used IP addresses in CN. GSLB is dynamic, however, and will calculate which datacenter is closest. I'm not sure what that means for HK. You could check - try to traceroute to www.mozillaonline.com (or try to ping that address). If you get 59.151.50.0/24 you're in China, 63.245.209.0/24 is in San Jose (63.245.213.0/24 is in Amsterdam but mozillaonline.com isn't being hosted out of there).
