This article surveys home connectivity technologies. It covers both home LAN and broadband connection options.

Contextual search

Using the Net to share bicycles

This article describes a unique application. Thousands of commuters in Lyon, France, are using pedal power instead of gas, under an ambitious new program that lets people rent bikes from public racks at low cost.

This blog covers Internet applications and technology and their implications for individuals, organizations and society. Check the tag cloud to the right to see some coverage key words or skim over the last 5 or 10 posts to see if they sound interesting.

I have a couple of other blogs, listed on the right, which might also be of interest.
