As of 12/4/2016 the servers are now in their new homes, the web server in Fremont and the archive server emma in Santa Cruz. Some of the pre-2004 archive programs are not yet online but will be soon. Your support is essential if the service is to continue, there are bandwidth bills to pay every month and failing disk drives to replace. Volunteers do the work, but disk drives and bandwidth are not free. Click on this bar to contribute, even a dollar helps.

The BBC reports about Li-Fi, which delivers data much faster using visible light.
Produced for air Nov. 30, 2015, but can run a few days later.
The BBC reports about a new method of delivering data that s being successfully tested, using the visible spectrum rather than invisible radio waves. So-called li-fi can deliver internet access 100 times faster than current wi-fi, with up to 1 Gbps. A standard LED bulb, an internet connection, and a photo detector are used by the Estonian start-up company Velmenni. The company s laboratory tests have proven theoretical speeds of 224Gbps. The company s chief executive Deepak Solanki predicts consumers will be using li-fi within three to four years. Professor Harald Haas from Edinburgh University first demonstrated the technology at a TED conference in 2011, showing how it does not interfere with other radio signals, and uses a part of the radio spectrum, the visible waves, that s 10,000 times larger then where radio waves currently travel. Sunlight is li-fi s kryptonite, and it does not travel through walls, so this is an end-of-the-line technology for large office buildings.
