# Key Points from #hplusroadmap IRC Discussions

• Security vulnerabilities were highlighted through discussions of BadUSB exploits and Google Project Zero's research on DRAM rowhammer bugs that enable kernel privilege escalation.

• 3D scanning technologies were extensively analyzed, comparing structured light systems (like Intel RealSense F200) with Time-of-Flight (ToF) cameras, with participants noting that ToF likely "degrades more gracefully with movement."

• Technical details of Intel's RealSense camera were examined, explaining how it uses structured light technology where projected patterns are deformed by objects, allowing 3D reconstruction through parallax between the IR camera and laser projector.

• DIY approaches to structured light 3D scanning were discussed, including using regular cameras with projectors or creating custom projectors using magnifying glasses or fresnel lenses with LED light sources.

• Participants shared information about biohacking spaces in the San Francisco area, including Biocurious, Counter Culture Labs, Berkeley Bio Labs, and Indie Bio.

• Tesla's gigafactory in Reno, Nevada was noted for its ambitious plan to produce 35 gigawatt hours of battery cells annually by 2020, which would "more than double the current entire world's lithium ion battery production."

• A distributed application called ALEXANDRIA was mentioned as being introduced through the unSYSTEM mailing list, though specific details weren't elaborated.
