Ariel Procaccia and Jonathan Goldman of Carnegie Mellon University have taken it upon themselves to make fair division problems easier to solve with a flashy new website called Spliddit (eyy, fuhgeddaboudit).

The conclusions you can draw from this graph will SHOCK you
This is a blog post based on a Google+ post about a tweet. I can only hope that it will inspire a further flourishing of vines, instagrams and Yo!-s.
I saw this graph (originally from job stats site msgooroo.com) posted by a functional programming news site:
“More reasons to choice Functional Programming – #Clojure and #Haskell highest paying #engineer salaries!”.
Well, should I “choice” Haskell or Clojure, based on the evidence in this graph?
Logically Policed
This is a nice short documentary by student filmmaker Damiano Petrucci about mathematics and mathematicians, why they do maths and how they communicate it. It’s got a load of names you’ll recognise, including Oxford’s Ben Green and Aperiodipal Matt Parker.

K sera, sera: board of the Journal of K-Theory resigns (again) and starts a new journal (again)
The rumours are true: the editors which in 2007 resigned from the journal K-Theory have now resigned from the splinter journal they helped set up, Journal of K-Theory, to start a third journal, Annals of K-Theory. What a headache!
Petition absorbs way more signatures than this product with a stupid advert ever could
An Australian sanitary pad company has hit upon a witty tagline for their product:
Literally thousands of people have signed a petition to tell Libra that that’s not OK.
Integer Sequence Review – Sloane’s birthday edition!
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.
CP: It’s Neil Sloane’s 75th birthday today! As a special birthday gift to him, we’re going to review some integer sequences.
DC: His birthday is 10/10, that’s pretty cool.
CP: <some quick oeis> there’s a sequence with his birthdate in it! A214742 contains 10,10,39.
DC: We can’t review that. It’s terrible.
CP: I put it to you that you have just reviewed it.
DC: Shut up.
CP: Anyway, I’ve got some birthday sequences to look at.
DC: About cake?
CP: No.

Blooming Zoetrope Sculptures by John Edmark
John Edmark has 3d-printed a series of sculptures which do something rather remarkable when you rotate them. In the stop-motion animation above, the sculpture rotates by the golden angle in each frame.
