• MIT Media Lab’s Raskar group released a paper on coded-aperture optical heterodyning that enables low-resolution imaging; an interactive demo of the accompanying deblurring algorithm was also shared.

• Participants debated whether LCD-based shutters can reach 1/1000-second exposures and how such ultra-fast non-mechanical shutters could be integrated with the new coded-aperture techniques.

• Y Combinator’s seed investment in Ginkgo Bioworks was criticized as superfluous because the company already had revenue; the channel also noted YC’s broader biotech push and flagged a “Ginkgo is hiring” post on Hacker News as spam.

• The complete open-source assembly guide for the OpenTrons BioBot 1.0 liquid-handling robot was mirrored at files.synbiota.com and diyhpl.us, making the hardware fully reproducible.

• A request arrived to redact historical Extropians mailing-list archives; the maintainer compared Wei Dai’s archive version against diyhpl.us to check for prior redactions, citing the theory that Wei Dai could be Satoshi Nakamoto as a reason for extra scrutiny.

• Paperbot, the channel’s paywall-bypass bot, crashed with a Python recursion-depth error while fetching an IOS Press article; users were invited to submit bug fixes.

• Paperbot successfully retrieved two additional paywalled papers: a Phys. Rev. Lett. on laser-plasma interactions (10.1103/PhysRevLett.113.035001) and a NeuroImage study (S1053811914002158).
