[time-nuts] GPS through windows

The low-E coatings are known to attenuate WIFI. WIFI is probably a worse case than GPS, but the availability of the gear makes experimenting easy. I think they are sputtered metal either on the glass or on a thin film applied to the glass. Southwall Technology in Palo Alto pioneered or at least commercialized the technology. 

Pay-walls on technical journals have to go. The IEEE doesn't pay the author for the article. They used to make the author pay a small fee. Anyway, the exorbitant fees of technical journals discourages cross-discipline research. You can't be a member of every one of these societies. 

The US government papers (Department of Energy for instance) are free on the DOE websites, but under a paywall on other government websites. (AKA left hand not talking to the right hand.)

End of soap-box rant.
