  • Stellar classification – Wikipedia – In astronomy, stellar classification is the classification of stars based on their spectral characteristics
  • Carbon star – Wikipedia – "A carbon star is typically an asymptotic giant branch star, a luminous red giant, whose atmosphere contains more carbon than oxygen; the two elements combine in the upper layers of the star, forming carbon monoxide, which consumes all the oxygen in the atmosphere, leaving carbon atoms free to form other carbon compounds, giving the star a "sooty" atmosphere and a strikingly ruby red appearance. There are also some dwarf and supergiant carbon stars, with the more common giant stars sometimes being called classical carbon stars to distinguish them." WAIT WHAT
  • How SciFi Can Solve the Problem of Red Dwarf Stars | Tor.com – "But the universe does not necessarily conform to reasonable expectations. A surprising number of red dwarfs have potentially habitable worlds in their tiny Goldilocks zones (as we now know, having learned to detect extrasolar planets). Proxima Centauri, for example, has one, despite the fact that its habitable zone is roughly the width of a piece of paper. Gliese 581 has one, too. TRAPPIST-1 has three and what’s up with that? It seems any quasi-realistic setting will have not just a surfeit of red dwarfs, but a surfeit of habitable worlds orbiting them. Sorry—potentially habitable. Let me explain." – put this way, you'd almost be *suspicious* of the number of planets that are in habitable zones, almost as if they'd been… put there?
  • Departing Facebook Security Officer’s Memo: “We Need To Be Willing To Pick Sides” – In a brutally honest note about his departure, Facebook’s Chief Security Officer Alex Stamos calls on his colleagues “to intentionally not collect data where possible” and listen to people when they say a feature is “creepy.”
  • Redditor suggests MacBook Pro throttling is not a CPU issue; can be fixed [U] | 9to5Mac – "A Redditor argues that the CPU slowdown experienced with the 2018 MacBook Pro is not caused by thermal throttling of the processor itself, but rather by power throttling of the voltage regulator module (VRM)."
  • Apple releases software fix for MacBook Pro slowdown – Six Colors – "Following extensive performance testing under numerous workloads, we’ve identified that there is a missing digital key in the firmware that impacts the thermal management system and could drive clock speeds down under heavy thermal loads on the new MacBook Pro."
