# Key Points from #hplusroadmap IRC Discussion

• Participants discussed transcranial direct current stimulation (tDCS) as a potential DIY brain enhancement technique, sharing information about using adjustable current supplies and homemade electrodes based on research showing electrical stimulation can enhance learning.

• The Seasteading Institute was noted for maintaining transparency, with participants sharing and discussing their executive summary document while debating design improvements such as more hydrodynamic float columns and semi-submersible platforms for better ocean stability.

• Detailed technical discussion about space habitat engineering covered structural specifications (10cm glass fiber walls with water shielding), optimal positioning at Lagrange points L4/L5 or in polar lunar orbit, and the necessity of self-replicating lunar factories for viable space colonization.

• Participants expressed frustration that space agencies seem focused on "space camping" rather than developing manufacturing capabilities in space, which they viewed as essential for meaningful space colonization.

• A conversation about educational systems included criticism of repetitive programming curriculum in engineering departments, with specific discussion of languages like C, Java, and MATLAB.

• Technical computing discussions touched on Linux variants, including Funtoo (a Gentoo variant with git-based Portage tree) and comparisons of resource usage between desktop environments like KDE 4.1 and GNOME 2.24.
