Update – October 2018: Although it’s not based on Netflow, Al Caughy’s YAMon provides a good view of the traffic flowing through an OpenWrt or DD-WRT router. I use it myself. Now that LEDE Project has an official release, I hungered for

You’ll see a popup window with a place to enter your phone number. Click OK, and they pop up a script on-screen. They call you, you answer, then you supply your zip code.
Although I usually agree with him, one of my favorite bloggers, Dave Winer, recently said this: One of the ideas circulating is that your ISP has a monopoly, owns the only way for you to get to the Internet, but that’s an old idea, it’s no longer true. Where I live the wireless vendors are

I’ve been playing with the spate of new Javascript technologies, and ran into a problem.
