# Summary of #hplusroadmap IRC Log (Oct 9, 2009)

* Discussion of alternative housing designs, particularly hexayurts, with debate about materials (OSB vs. plywood), waterproofing, insulation (Reflectix), and structural efficiency compared to other designs like square structures.

* Links to MIT's Center for Bits and Atoms (CBA) projects were shared, including http://ng.cba.mit.edu/show/video.html featuring innovative mechanical designs and http://cscott.net/Projects/FabClass/ showing fabrication technologies.

* Brief discussion about the influence of OLPC (One Laptop Per Child) on the development of the netbook market segment.

* Participants discussed preparation for an H+ Summit presentation, debating whether to focus on generic concepts versus specific implementations, and how to organize content about open source (GNU, FSF, OSI, Linux, Debian, Ubuntu) alongside DIY topics.

* A Focke-Wulf Triebfluegeljaeger aircraft design was referenced (http://en.wikipedia.org/wiki/Focke-Wulf_Triebfluegeljaeger) in relation to a hovering package delivery concept being discussed.

* Software development estimation was briefly mentioned with a link to COCOMO (http://en.wikipedia.org/wiki/COCOMO), a constructive cost model for software projects.
