- Skinput, a Sixth-Sense-style interface that turns the arm into a touch surface, was previewed at http://www.chrisharrison.net/projects/skinput/; its paper was scheduled for release on 12 April 2010.  
- Rapportive, a Firefox/Chrome add-on, was discussed for replacing Gmail ads with rich contact profiles, photos, and live social-media feeds.  
- A speculative “world-domination” cost model was circulated at http://heybryan.org/world_domination.html, estimating ~$300 T/year to “enslave the human race” and prompting debate on how venture capital and large financial institutions already pursue similar ends.  
- A 497 MB historical stock-market data set was mentioned as the basis for an ongoing simulation framework to test trading bots that deliberately accept many small losses in exchange for occasional large gains.  
- Interactive Brokers (IB) and the open-source ibpy library were noted as tools being used for live trading and algorithmic experimentation.  
- The open-source project-hosting platform FusionForge (behind Debian’s Alioth) was highlighted as a previously unrecognized resource for collaborative development.  
- Ikiwiki’s “untrusted git push” feature was praised for allowing offline, anonymous edits while still enforcing wiki-level access controls via server-side pre-receive hooks.  
- A new large-scale health-correlation study platform, Traitwise (http://www.traitwise.com/), was brought to the group’s attention.  
- Research on dopamine receptors D1 and D2 was summarized: D2 appears to mediate Ritalin’s focus-enhancing effect, while D1 underpins learning efficiency, though participants questioned whether dopamine is truly the primary mechanism of action.  
- A wearable-computing wish-list draft was posted at http://fennetic.net/irc/wearable_wishlist.txt, and troubleshooting continued on a misbehaving BeagleBoard thought to suffer from electromagnetic interference rather than hardware failure.
