Dmitry Orlov, Gluing of categories and Krull–Schmidt partners is a very short paper (just 4 pages) that discusses a neat construction of what Orlov calls Krull–Schmidt partners: given a semiorthogonal decomposition produce a (different) fully faithful functor, giving rise to a possibly new semiorthogonal complement. Fun!

Tamás Szamuely and Gergely Zábrádi, The padic Hodge decomposition according to Beilinson is survey article of recent development in padic Hodge theory. I only read the introduction (it is a bit outside my comfort zone), but I really liked the appearance of the htopology in which an algebraic version of the Poincaré lemma becomes true.

William Stein announces at the Benjamin Peirce centennial conference that he will leave academia and focus on making a company built on top of the opensource software Sage a success (video).
