# Key Points from IRC Log (September 15, 2009)

* Paul Rothemund gave a presentation at UT Austin about DNA origami, with notes mentioning that caDNAno (a DNA origami design tool) is written in Adobe Air, while NanoEngineer-1 is written in C and Python and released under GPL.

* Discussion about DNA origami included the observation that long DNA sequences containing occasional errors would still be usable for origami applications, unlike gene coding purposes, because only the total error rate matters rather than exponential error accumulation.

* Participants expressed frustration with the DIYbio community, criticizing its tendency to "reinvent the wheel" and noting that many members lack basic knowledge of both biology and computing technology.

* A debate occurred about whether to split off from DIYbio and create a more technically-focused group for scientific discussion without the perceived lack of technical rigor found in the DIYbio community.

* A participant shared information about electromagnetic metal forming, linking to research about molding metal with magnetic fields (http://www.tms.org/pubs/journals/JOM/9802/Li/Li-9802.html).

* Bryan Kanzure shared transcripts from two presentations: one by Rothemund on DNA origami (http://adl.serveftp.org/lab/2009-09-15-rothemund-utexas.html) and another by a Schlumberger speaker (http://heybryan.org/school/me136n/2009-09-15.html).
