While trying to compile sage-5.4beta1 on FreeBSD, it failed because of
another place using "#!/bin/bash". As I understand it, it should be
"#!/usr/bin/env bash".
This time it is in fflas_ffpack-1.6.0//src/fflas-ffpack-config.in
I'll file a ticket (except trac.sage isn't working for me right n

Some time ago I made an animation of the Hopf fibration using Sage.
Recently, a graduate of the African Institute for Mathematical Sciences
has finished animating a different map from S^3 to S^2. Ihechukwu Chinyere

This of course isn't an argument against caching in general. Actually,

Obviously, one should only cache functions that solely depend on the

Consider the following in sage:
Suppose I have defined f(x) for a range already, say by the following:
x = np.arange(0,1,0.001)
import matplotlib.pyplot as plt
plt.plot(x,f(x), color='magenta', lines

Upgrading to sage-5.3 is known to be broken, this will be fixed in sage-5.4.
