# Key Points from #hplusroadmap IRC Discussion

• Participants compared mailing list software options including Google Groups, Mailman, and Sympa, noting tradeoffs between spam prevention, moderation requirements, and code quality issues with Mailman despite its continued functionality.

• A technical discussion about database design addressed storing images as binary values versus file paths, concluding that while less storage-efficient, modern databases can effectively handle and index binary image data.

• Members shared research on novel gesture recognition technologies, including SoundWave (using Doppler Effect for sensing gestures) and WiSee (a whole-home gesture recognition system using Wi-Fi signals implemented with GNURadio and USRP-N210 hardware).

• Scientific papers were exchanged on light-controlled graphene-elastin composite hydrogel actuators, with participants requesting and sharing PDF versions through paperbot, resulting in text dumps accessible via diyhpl.us.

• The conversation included clarification of data storage terminology, specifically that "megabyte" should properly denote 10^6 bytes following SI conventions, while "mebibyte" (MiB) is the correct term for 1024×1024 bytes.

• The Emperor 1510 LX workstation was mentioned as an ergonomic computer setup that generated interest among the transhumanist community members.
