Wi-Fi Planet rounds up the uses of solar power for Wi-Fi and related wireless data nodes: The conclusion of this great comprehensive survey by Amy Mayer is that solar power isn't affordable for casual use, but it makes perfect economic sense in areas in which juice just isn't available at any reasonable cost, but the value of monitoring is high. It's also worthwhile when the pure capital costs of changing batteries are outweighed by the labor involved, as with a winery using ZigBee networking: they could swap AA batteries, but they'd be paying someone to do it.
Ars Technica debunks Wi-Fi/autism link so I don't have to: Thanks to Ars Technica and John Timmer for running down the reasons that the link between Wi-Fi and autism reported last week--which seemed entirely specious to me and I had thus ignored them--don't meet the smell test for a host of reasons. Perhaps the main reason is that the link appears to be that a heavy-metals detoxification method that's not recognized as curing autism, but is credited in the paper with such, was interfered with by Wi-Fi, according to these claims.
Explanation of Sprint Nextel's problem: It was like German reunification: The Washington Post reporter doesn't mention Wessies and Ossies (West and East Germans), but they should have. Sprint and Nextel apparently never quite merged, with Nextel's scrappy culture and Sprint's ossified one remaining distinct. Experienced Nextel workers left, taking their IDEN network knowledge with them--that's the unique network that simplified offering Nextel's early push-to-talk technology, and that Sprint is dismantling. The Wiedervereinigung--sorry, the merger--left workers in duplicated positions competing with each other, which left bad feelings. Headquarters were left in two locations. A new Chancellor--er, CEO is expected to have to resolve these cultural problems.
