# Summary of #hplusroadmap IRC Log (June 23, 2013)

* A user mentioned they were preparing to use a liquid-cooled polycarbonate printing hot end with a 0.45mm nozzle for 3D printing, indicating ongoing DIY hardware development in the community.

* Discussion about programming language limitations revealed that CPython threads cannot be used effectively for CPU-heavy loads as they run on a single core due to the Global Interpreter Lock (GIL), while Jython doesn't have this limitation but lacks Python 3.x support.

* Research was shared about genetic evolution showing that transcription factor binding sites are three times as mutable as protein-coding genes in humans, suggesting an important mechanism for human evolutionary changes.

* Members discussed EEG technology limitations, particularly regarding consumer-grade devices like the Melon headband Kickstarter project, with skepticism about claims of measuring "focus" with only three electrodes and disappointment in the marketing of such devices as advanced brain-computer interfaces.

* The conversation revealed a cultural divide between biologists and computer scientists, with participants noting that despite biology becoming "an information science," many biologists remain resistant to computing tools and platforms like IRC, limiting collaboration between these communities.
