# Summary of IRC Log from #hplusroadmap (May 25, 2013)

* Users shared and discussed papers on microfluidic technology, including a paper on micro pneumatic valves with double-layer elastic membranes and another on label-free biodetection using smartphones.

* A detailed technical discussion occurred about microfluidic valve systems, covering pressure requirements (15-25 PSID), the use of water instead of air in pneumatic control lines (to prevent air leaking through PDMS and creating bubbles), and various valve actuation mechanisms.

* The NanoEngineer molecular design software was briefly discussed, with a link to its GitHub repository (https://github.com/kanzure/nanoengineer) being shared.

* A tool for CSS debugging was shared (http://css.benjaminbenben.com) that uses PhantomJS to visualize which CSS rules are applying to different elements on a webpage.

* Users discussed the economics of cloud storage, noting that Amazon S3 charges approximately $95/TB-month, which is roughly equivalent to buying a new hard drive every month.

* A link to a Wikipedia article on "Degree of anonymity" was shared, potentially relevant to discussions about privacy and information security in technological systems.
