# Summary of #hplusroadmap IRC Log (Nov 9, 2009)

* A user mentioned contacting Hod Lipson to request source code from his paper "Towards a Universal Knowledge Database for Design Automation," indicating interest in design automation research.

* Utopiah shared a link to a statistical analysis of open design titled "Open source enters the world of atoms," highlighting the expansion of open source principles beyond software.

* Discussion about microfluidic devices focused on technical approaches for DIY fabrication, with explanations that at microfluidic scales, valves operate differently due to low Reynolds numbers where liquids behave more like syrup.

* A detailed technical exchange covered fluidic microprocessors, with clarification that they can be made without photolithography equipment by using laser-cut acrylic and fluidic amplifiers rather than traditional valves.

* The conversation included references to advanced microfluidic techniques including electrokinetic flow, rubbery microfluidics, and the "shrinky dink" technique for creating microfluidic molds.

* A link was shared to a paper on Stanford's microfluidic valve technology that uses pressure-activated channels that expand like balloons to control fluid flow.

* Kanzure found a resource for Wikipedia statistics (http://dammit.lt/wikistats/) as an alternative to downloading the entire Wikipedia database.
