# Key Points from #hplusroadmap IRC Discussion

• Participants discussed various neural network resources, including a Noisebridge Neural Network Workshop and related code repositories, demonstrating the community's interest in practical AI implementation.

• The conversation covered advanced manufacturing techniques, particularly stereolithography (3D printing) methods comparing DLP projectors versus masks, and CNC machine techniques for PCB fabrication that use continuity testing for Z-axis sensing to compensate for board warping.

• A chemocentric informatics approach to drug discovery was discussed, specifically identifying selective estrogen receptor modulators as potential cognition enhancers, reflecting the group's interest in pharmaceutical cognitive enhancement.

• FPGA development challenges on Linux were highlighted, with users noting the proprietary nature of toolchains like Xilinx and sharing potential open-source alternatives like XESS (http://www.xess.com/prods/prod048.php).

• The community showed interest in cognitive enhancement compounds including Trental (pentoxifylline), Provigil (modafinil), NAC (N-acetylcysteine), and piracetam, discussing sourcing challenges and international procurement options.

• A participant shared their work modifying the GRBL controller software to output additional status variables like current position and feed rate, demonstrating the hands-on engineering focus of the community.

• The Open Science Summit 2012 at the Computer History Museum in Mountain View was mentioned, showing the group's engagement with broader open science movements and events.
