Each entry is phrased as the falsehood. Some of these may sometimes be true and sometimes be false. If I don’t have a RFC 1918 address, I’m not behind a NAT. Okay, only IP, IPX/SPX, Phase IV, AppleTalk, VINES, NetBEUI, or SNA are running on my LAN. MAC addresses are globally unique. (They’re supposed to be, but they aren’t.) The first three bytes are vendor‐unique if it’s a MA-L block.

Finite time blowup for an averaged three-dimensional Navier-Stokes equation (2014)

The author has formalized the "supercriticality barrier" for global regularity of the Navier-Stokes equation, showing that no abstract approach can establish global regularity without additional assumptions. A modified version of the Navier-Stokes equations with a nonlinearity obeying function space estimates and energy identity leads to finite time blowup.

How Swiss tables work in Go built-in map

Go's Swiss Table implementation for maps uses a triangular probe sequence to find empty slots, allowing for efficient lookup and insertion operations with minimal scanning cost. The new implementation also optimizes memory usage by storing keys together during search and using less padding space when the value array is empty, resulting in faster map operations compared to previous versions.
