First code of conduct for a TCS conference (G+, via). I think this is a move in the right direction.

Lattices with exponentially large kissing numbers (G+). Gil Kalai describes a new preprint by Serge Vlăduţ.

Earthmover distance (G+), and why it might be relevant for gerrymanderingrelated computations.

UK academics reach the third week of a general strike over significant reduction in their retirement packages (G+), while the universities simultaneously call off negotiations and ask strikers to return to work while negotiations continue.

A regiment of monstrous functions (G+). Realvalued functions, even the ones defined by simple formulas, can behave badly.

Sir Robin (G+). A new and notenormous spaceship in Conway’s Game of Life that moves in the direction of a chess Knight at speed . With later indepth discussion of how it was found (G+), and bonus unsolved problem in graph theory (on graphs in which each edge belongs to a unique triangle and each nonedge is the diagonal of a unique 4cycle), potentially within reach of computation.

The Erdős paradox: When a mathematical number and Wikipedia collide (G+, via). Interview with Kirsten MengerAnderson on how (in an essay I linked earlier) she was led from Erdős numbers to missing women mathematicians on Wikipedia.

The rulers of the empire of the east try lipograms as a mass cultural word game (G+, via). Because somehow that makes it harder to protest the removal of term limits.

Turning surface meshes in 3d into instructions for an automatic knitting machine (G+, via, via). You would think that a tea cozy for the Utah teapot would make a good test case, but no, they knitted the Stanford bunny instead.

Chalkdust Issue 7 (G+). This British recreational mathematics magazine features articles on a settheoretic roadtrip game, the classic nine dots puzzle and its extensions, a Menger spongecake recipe, and more.

Sequence 300k for the OEIS (G+, via). Beyond this milestone, the linked post includes some details about four nice new sequences.

Beall’s list of predatory journals, resurrected (G+). With some discussion of IJCGA spam in the G+ post.
