Code released after hackers gained root access to headset
Google has released the kernel GPL source code for Google Glass, in an effort to provide developers more information on how Glass actually functions. The download, measuring in at around 65 megabytes, comes in the wake of hardware hackers successfully gaining root access to a developer edition of the device within hours, by using already-existing Android exploits.
The code is currently hosted on Google servers, though it is warned that the site is "unlikely to be the permanent home for the kernel source," and should be relocated to similar storage to other Android source files in the future.
An initial look at the source by Karthik's Geek Center seems to show that NFC headers were left in the code. While it is possible that Glass may have some sort of NFC support, if not in the developer edition then in the consumer release, it could also be leftovers from when the Glass team worked on the software but failed to remove them before the code's release.
