The European Space Agency is contemplating 3D printed moon-bases:
By using the Moon’s loose rocks (regolith) as a base for concrete, robots based on Monolite’s D-Shape 3-D printer will be able to build up a structure that uses as many local materials as possible. The idea is that with a shell made of moon rocks to act as a shield against micro-meteors and similar hazards, the living quarters for moon colonists could be inflatable envelopes protected by these shells.
3-D printing concrete in a vacuum is very, very different from printing it on earth. The teams have been experimenting with simulated moon rock material in vacuum chambers to find methods of construction that work. The problem being that concrete relies on applying liquids and unprotected liquids boil away when there’s no atmosphere. They discovered that by inserting the 3-D printer’s nozzle underneath the regolith, capillary forces kept enough liquid in place long enough to set properly.
This is also the premise of a novella I'm writing for Neal Stephenson/Arizona State University's Heiroglyphyics project. Nice to see reality clipping along!

Octavia Butler (previously), the brilliant Afrofuturist, McArthur Genius Grant-winning science fiction writer, died far, far too soon, leaving behind a corpus of incredible, voraciously readable novels, and a community of writers who were inspired by her example.
EFF has just posted a job listing for a development director, seeking someone to "take charge of EFF's eleven-person Development Team in their efforts to raise over $13 million each year," starting late 2019 or early 2020.
On the one hand, nostalgia is “a corruption of the historical impulse,” according to William Gibson. On the other hand, “Super Mario Bros.” will never not be cool. Luckily, there’s a way to satisfy that retro gaming while still keeping an eye on the future: The GameShell Kit. This thing is simultaneously the last handheld […]
The field of data analytics can get intimidating, even for business professionals who constantly rely on it. But at its heart, its purpose is to simplify. To take mounds of information and distill their insights into a single clear picture. Currently, the go-to software for painting that picture is Tableau. And if you want to […]
