A technical essay revisits Gary Bernhardt's decade-old 'Functional Core, Imperative Shell' architecture, arguing that the key property enabling easy testing isn't functional purity itself but determinism. The author suggests that state machines and other deterministic constructs can achieve the same testability benefits as pure functions, broadening how developers might structure isolated, predictable 'core' logic versus the messier, IO-heavy 'shell' that talks to the outside world.

Reviews from Notebookcheck and PC Gamer found that external GPU enclosures connected via Thunderbolt suffer meaningful performance losses compared to desktop PCIe slots, ranging from 7 to 32 percent depending on resolution and card. PC Gamer found an RTX 4070 Ti ran about 25 percent slower over Thunderbolt than OCuLink, with worse stuttering and lower frame-rate consistency, and found that pairing an eGPU with a faster RTX 4090 yielded diminishing returns versus a full desktop connection.

A study slated for publication in Physical Review D proposes that neutrinos switching between types inside a collapsing star's core could help resolve long-standing mismatches between supernova models and observations. Current simulations of core-collapse supernovae largely ignore this flavor-swapping behavior, even though neutrinos play a central role in triggering the explosion. The researchers suggest accounting for these identity changes could bring predicted supernova rates and outcomes closer to what astronomers actually observe.
