Stomp*3 Bayesian RSS Aggregator
: "The Growlmurrdurr RSS aggregator is a piece of software which reads RSS feeds and allows access to them through a CGI web interface. It presents a simple and clean layout of all the news articles from the RSS feeds in chronological order. Additionally, it allows you to use Bayesian filtering to group RSS news items into two catagories, presumably the ones you're interested in and the ones you're not. It is geared towards aggregating many, many news feeds simultaniously and features the ability to specify individual reload times for each feed. It is written using Python. Python 2.3 or later is recommended as earlier versions may not work. Bayesian filtering software has been yanked out of SpamBayes. The RSS parsing module has been taken from pyblagg."

Wi-Fi service, product news: "Public IP Services of Pine Beach, New Jersey, has developed a solution specifically designed for small restaurants, hotels, laundromats and bars that want to differentiate themselves or encourage patrons to stay longer .. The ISP charges businesses US$69.95 per month for hotspot access. The service includes Netopia's 3-D Reach 3347W ADSL wireless gateway, which features an ADSL modem, Wi-Fi certified access point and Ethernet switch on one box. ..
Rich Mironov is AirMagnet's vice president of marketing. The Framingham, Massachusetts-based company has found that high-tech, education and government sectors have been quickest to deploy Wi-Fi, followed closely by healthcare, manufacturing and telecom. .. His company's [sells a] line of analysis and management products, which patrol Wi-Fi network perimeters for security and performance issues. " 9:45:53 AM
Nanosys filing for IPO, changing product plans:
"One minor shift is that the company no longer expects its initial products to be biosensors .. Instead, the company is working with the government on biosensor applications. Nanosys has also added nonvolatile memory to the markets it seeks to penetrate, according to its recent filing. Given the subtle shifts, [analyst] Sanchez said, the most likely initial product would be solar cells
Thiemo Lang, a portfolio manager with mutual fund firm Activest, said the IPO might be a bit early. “This will be very interesting to follow,” he said. “I think they see that the stock market is quite favorable for them.” Lang created the Activest Lux NanoTech mutual fund in 2002. " 9:42:49 AM
34% Americans have broadband, 24% have broadband at home:
"Also, 68 million Americans - or 34% of all adults - have access to high-speed Internet connections either at home or on the job. 48 m or 24% have high-speed access at home. Home broadband adoption is up 60% since March 2003.. DSL now has a 42% share of the home broadband market, up from 28% in March 2003. For the first time, more than half (52%) of college educated people age 35 and younger has broadband connections at home. Only 10% of rural Americans go online from home with high-speed connections, about one-third the rate for non-rural Americans." 9:18:07 AM
Material grabs more sun: "Most photovoltaic materials absorb a relatively narrow range of light energy [from one band gap].. Researchers from Lawrence Berkeley National Laboratory, the University of California, and MIT have engineered a single material that contains three bandgaps and is capable of capturing more than 50 percent of the sun's energy. The researchers made the material by forcing oxygen into a zinc-manganese-tellurium crystal. The oxygen split the crystal's band gap and formed a third one of its own. ..
It will take to three years to assess the technical feasibility of the multiband solar cell, according to the researchers. The work appeared in the December 12, 2003 issue of Physical Review Letters". See also here. 9:13:15 AM
