# Summary of IRC Log from #hplusroadmap (April 27, 2015)

* A user mentioned working on "high density biological oxygen storage" but noted it was "terribly reactive at 37°C" (body temperature), with another user later suggesting nitrate as a less reactive alternative for oxygen storage.

* A researcher shared a live demo of their question-answering (QA) system at http://live.ailao.eu/, which appears to be an AI-based information retrieval system.

* A discussion about virtual reality technology occurred, with a user sharing an image of VR users and commenting that they "should at least hold something with the momentum of a sword" for more realistic feedback during gameplay.

* A user inquired about manufacturing custom covers similar to those used by Eero (wireless networking devices), mentioning they needed approximately 5,000 units with 20-30 initial prototypes.

* There was a brief discussion about version numbering conventions for app store submissions, with a user asking if version numbers like "0.0.2" or "1.0.002" would be rejected.

* Several references were made to a "paperbot" service that appears to be a research paper retrieval or sharing tool used by the community, though it wasn't operational during this log session.
