# Summary of #hplusroadmap IRC Log (April 27, 2016)

* OpenAI Gym was shared (https://gym.openai.com/), a platform for developing and comparing reinforcement learning algorithms.

* A discussion about DIY spectroscopy techniques occurred, including methods for using cameras with diffraction gratings, with recommendations to use DSLRs without lenses for better results.

* Resources on spectroscopy were shared, including a comprehensive diffraction grating handbook and a spectrometer design guide that explains angle calculations.

* A conversation about "sleeptype" output was mentioned, suggesting someone was tracking or recording sleep data or sleep-talking.

* A critique of an NJU iGem team project was discussed, questioning why they weren't developing virus-based receptor agonists as an alternative to existing antagonists.

* A Bitcoin-related article from MIT was shared discussing how democracy is "antithetical to what Bitcoin represents" (https://bitcoinmagazine.com/articles/mit-panel-democracy-is-antithetical-to-what-bitcoin-represents-1461771081).

* A technical suggestion was made about using multiple diffraction gratings at 90-degree angles to separate overlapping wavelength orders in spectroscopy.
