# Key Points from #hplusroadmap IRC Log

• The log primarily contains connection/disconnection messages with minimal substantive discussion.

• A participant described learning to pull micropipettes with 500nm tips using a Sutter P-97 machine, explaining how the device uses a platinum heater coil to heat a capillary held between tensioned grippers.

• Users compared DNA synthesis technologies, discussing the tradeoffs between inkjet DNA synthesizers and lithographic patterning methods, noting that while lithographic approaches offer higher spot densities, inkjet might have lower error rates for standard applications.

• A resource on code refactoring (sourcemaking.com/refactoring) was shared and appreciated by another user who was managing a large 2,000-line class in a telnet implementation.

• There was brief discussion of spin-coating techniques for bacteria, with reference to a paper titled "Oriented Colloidal-Crystal Thin Films by Spin-Coating Microspheres Dispersed in Volatile Media."

• Several scientific papers were shared through the channel's paperbot system, including research on energetic particle radiation during Mars transit and methods to prevent jet lag when traveling.
