# Key Points from #hplusroadmap IRC Discussions (March 17-18, 2016)

• Researchers discussed a paper on "Stimulation-based control of dynamic brain networks" that explores techniques for targeted manipulation of brain activity through stimulation.

• Participants shared the "Spaun" large-scale brain model (with GitHub repositories), which implements complex neuron models using the Nengo framework for detailed neural simulations.

• A participant reported experimenting with nicotine gum as a nootropic, claiming 20-30% subjective improvements in focus and mood, prompting discussion about cognitive measurement and placebo effects.

• A critical security vulnerability affecting all git versions before 2.7.1 was announced, involving both server and client-side remote code execution through buffer overflow (CVE-2016-2324 and CVE-2016-2315).

• The group discussed Sprengel pumps (mercury-based vacuum devices) for potential use in self-replicating systems, considering alternative materials like gallium, indium or lead-based solder alloys to avoid mercury toxicity.

• Mars exploration vehicle options were debated, with dirigibles/blimps being favored over helicopters due to Mars' thin atmosphere, with some suggesting this constraint as motivation for "fast-terraforming" efforts.
