Limit iPhone radiation exposure + boost signal strength
January 02, 2008 (early evening)
Flipping through the iPhone manual, I happened upon this nugget of info.
“For optimal mobile device performance and to be sure that human exposure to RF energy does
not exceed the FCC guidelines, always follow these instructions and precautions: When on a
call using the built-in audio receiver in iPhone, hold iPhone with the 30-pin connector
pointed down toward your shoulder to increase separation from the antenna.”
Translation: Keep you hand off of the plastic antenna cover.
I wondered if anyone had measured changes in signal strength when “holding the iPhone properly” and sure enough Nate True posts ”iPhone tip - want better EDGE speeds? Take your hand off the antenna” He claims that he sees a 50% speed increase. It seems a bit faster to me, but who knows.
R.I.P. Netscape Again?
December 29, 2007 (late morning)
AOL has declared Netscape dead. Has this not happened before? ”AOL Cuts Remaining Mozilla Hackers” (2003)
Most people have considered it dead for quite some time. How many people have even heard of Netscape 9.0? Asking around, none of the developers I know have.
This might be the end of the AOL Netscape era, but certainly not the end of Mozilla. Anyone ever heard of Firefox? How about Seamonkey or Camino?
