- Discussion of ISO 10303 (STEP) standard: ybit noted its surprising size and asked kanzure for previously-downloaded Application Protocols (APs); kanzure replied that he had tried to extract APs from fileopen.ansi.org but could not reverse-engineer the base64 encoding required by DisplayManager.aspx.

- genehacker asked whether breaking CAPTCHAs is “easy,” hoping to automate extraction of equations from a materials-processing textbook; kanzure responded that recognizing equations is harder than solving CAPTCHAs.

- genehacker linked to a Next Big Future article on “electron-fluidic logic” as a post-CMOS candidate technology.

- kanzure posted an open-source, kit-free high-throughput miniprep protocol for DNA extraction on OpenWetWare (http://openwetware.org/wiki/Miniprep_-_Kit-free_high_throughput_protocol_-_source_code).

- ybit uploaded a 1994 paper titled “Building MRSEV Models for CAM Applications” to the adl.serveftp.org papers archive.

- kanzure shared a gallery of “arborsculpture” or tree-sculpting examples, illustrating biological fabrication techniques.

- kanzure mentioned “phduino,” presumably a pH-sensing Arduino project.

- ybit provided a link to the CMU Arctic speech corpus (http://www.speech.cs.cmu.edu/cmu_arctic/packed/) for open-source speech synthesis datasets.
