Looking for an open source alternative to Mathematica or MatLab for solving algebraic equations? Look no further than the excellent SymPy project. It is a well built and easy to use Computer Algebra System (CAS) and in this episode we spoke with the current project maintainer Aaron Meurer about its capabilities and when you might want to use it.

How do you make the bell icon on Google pages not notify you for +1s?

New blog post, based on a notebook I made awhile back. "What happens when you mess with hashing in Python"

Last Friday was my last day working at Continuum Analytics. I enjoyed my time at the company, and wish success to it, but the time has come for me to move on. Starting later this year, I will start working with Anthony Scopatz at his new lab ERGS at the University of South Carolina.

During my time at Continuum (over two years if you count a summer internship), I primarily worked on the Anaconda distribution and its open source package manager, conda. I learned a lot of lessons in that time, and I'd like to share some of them here.

I've started looking at migrating the +SymPy issues from Google Code to GitHub. However, every script I've found so far doesn't work (I can't even get past the authentication stage). 

Before I end up hacking together my own thing, does anyone know of a script that actually works? Anyone know of some projects that did a similar migration that I can get into contact with?

SymPy 0.7.4 has been released. Download from, or pip
install --upgrade sympy. If you use Anaconda, you should be able to
conda update sympy as soon as Continuum updates it in their repos.

The full release notes for this release are at  Some

- SymPy now uses a single code-base for Python 2 and Python 3. This
version of SymPy supports Python 2.6, 2.7, 3.2, and 3.3, all with the
same tarball.

- The geometric algebra module has been refactored.

- CSE (common subexpression elimination) is now much faster.

- New functions for cryptography.

- New Diophantine equation module (Thilina Rathnayake's GSoC project)

- New Lie Algebra module (Mary Clark's GSoC project)

- Improvements to the polys module. For instance minpoly() now
supports algebraic functions in addition to algebraic numbers (Katja
Sophie Hotz's GSoC project).

See the release notes and the git log for a full list of changes. See for a full report
on the 2013 GSoC program. See
for the full documentation.

Thanks to everyone who contributed to this release!

Some PyPI statistics show that almost no one uses Python 3, compared to 2.6 and 2.7. This is starting to be embarrassing.
