In ‘asking people on the internet to do things for you’ news: mathagogy.com is asking for submissions from teachers of two-minute videos, describing how they would approach teaching a particular aspect of mathematics.
Peps Mccrea makes the pitch in this positively fleeting 69 second video:

The Online Encyclopedia of Integer Sequences contains over 200,000 sequences. It contains classics, curios, thousands of derivatives entered purely for completeness’s sake, short sequences whose completion would be a huge mathematical achievement, and some entries which are just downright silly.
For a lark, David and I have decided to review some of the Encyclopedia’s sequences. We’re rating sequences on four axes: Novelty, Aesthetics, Explicability and Completeness.

I had hoped that The Future of Scholarly Mathematical Intercourse would arrive chaperoned by The Future of Publishing.
The first papers in Cambridge University Press’s new journals, Forum of Mathematics Pi and Forum of Mathematics Sigma, have been published — $p$-adic Hodge theory for rigid-analytic varieties by Peter Scholze in FoM Pi, and Generic mixing theory via vanishing Hodge models by Minhea Popa and Christian Schnell in FoM Sigma. But since the journals are more interesting for the medium they’re delivered by than their message, I’d like to take a look at the experience I had when accessing them.

Following last week’s palaver, we’re going to do our best to be serious this time. Game faces on. David promises there will actually be some maths in this sequence.
