Not just for philosophers...
 
If you want to print the “Git for philosophers” piece, I made a release of the Git version with PDF and HTML versions. Here’s the PDF of Git for philosophers.

I think +Richard Zach​ just wants to get his (potential) coauthors up to speed. I know +Steve Awodey​ uses it.

The Hungarian mathematician Ágota Figula has put up (what looks like) all her papers on the arXiv in the last few days, dating back to 2003:

http://arxiv.org/find/math/1/au:+Figula_A/0/1/0/all/0/1

I love it when people do this...

It's all the fault of teh arXivez!!!11!! (cf https://xkcd.com/386/)

I'm not registering just to debunk, since it should be obvious that the problem is not that papers are released early, but that people are practically forced, by the pressure to get a grant, to get the next job etc, to hype up their own results.

ADDED:
Compare with http://www.theatlantic.com/technology/archive/2012/07/the-case-study-of-arsenic-life-how-the-internet-can-make-science-better/259581/
 
Tighten the requirements for declaring physics breakthroughs, says Jan Conrad.

Haha, it's probably my fault then :) I was referring to theorems before they are labeled.

Mary Ellen Rudin proved theorems, "but it wasn't just theorems. She created examples—some easy, some difficult, and some which were breathtaking, almost audacious. Her theorems and examples cut a wide swath through a world that, when she began, was known as point-set topology and which relatively soon, in large part because of the kind of work she did and the kind of influence she had on others, came to be known as set-theoretic topology," writes Judith Roitman. See more memories by colleagues, collaborators, and students celebrating Mary Ellen Rudin’s life and work in "Memories of Mary Ellen Rudin" (1924-2013) in Notices of the AMS at http://bit.ly/1C9hEYL.

She and her husband Walter were legendary at Wisconsin when I was a PhD student there.  A very nice person who was amazingly productive as a mathematician given the circumstances of her career.

Born in 1912 China, [physicist Chien-Shiung Wu]  heavily involved in politics and protests as a student, came to the US in 1936, and enrolled at Berkeley for physics because her first choice school (Michigan) wouldn’t even allow women to use the front door. Her family couldn’t attend her wedding because WWII had broken out in the Pacific theater. She worked on the Manhattan Project, and went on to conduct the famous experiment that demonstrated parity violation (among many other things). She continued as an activist both in the US and internationally til her death. They called her the “First Lady of Physics.” Movie. We need one.

In the 1950s, physicist Chien-Shiung Wu was doing research at Columbia University when two other physicists approached her with a bold idea, but no way to prove it—until Wu found one.

A rare example of a pure mathematics paper (and a very interesting one!) in a general science magazine! Bravo to +Daniel Moskovich and Avishy Carmi (and I note +Marius Buliga and +Louis Kauffman got a mention :-) For completeness, here's the arXiv version: http://arxiv.org/abs/1404.2862
 
Tangle Machines is published. And our figure was chosen for the cover.

This looks interesting. First I've read of tangle machines.
"Section 5 discusses how [tangle] machines can represent networks of adiabatic quantum computations and presents equivalent machines which perform the same computations, but with different energy gaps."

Impact factors, what are they good for?

The following shows the distribution of impact factors (IF) of journals in the categories 'mathematics' and 'mathematics, applied', for the recently released impact factors calculated by Thompson Reuters. They write

This is a box plot of the subject category or categories to which the journal has been assigned. It provides information about the distribution of journals based on Impact Factor values. It shows median, 25th and 75th percentiles, and the extreme values of the distribution.

That outlier at about 7.2 is a new journal in numerical methods that hasn't published a lot. The other, much smaller points above the 75th quartile are journals like the Annals of Mathematics, Journal of the American Mathemtical Society, Communications in Pure and Applied Mathematics, Acta Mathematica -- which, I should point out, have a similar effect in one's CV that a Science paper does for other areas.

To compare, the mean IF for the subject area 'multidisciplinary science', which includes glossy mags such as Nature and Science is about that of Annals of Mathematics. I would posit it is much, much harder to get a paper into the Annals than a mid-ranked-by-IF general science journal.

Introduction
I live in Adelaide, Australia.

I am a pure mathematician who works on category theory and a smattering of related fields such foundations and higher geometry.

I works as a data analyst, of sorts, at the National Centre for Vocational Education Research (all views expressed here are my own).

I am a visiting fellow in the School of Mathematical Sciences at the University of Adelaide.
