Yes, Sage 3.1.2 fixes the problem.
It looks like Marshall's method of multiplying a list of numbers with
a constant is much faster then a for loop.
I wrote two list tests:
def test1():
for k in range(10^3):
v=[2*random() for j in range(10)]
else: pass
def test2():

As advised, I removed the broken installation I obtained via sage -upgrade and
installed sage 3.1.2.
Plotting worked nicely, until roughly 5 minutes ago. Now I get:

It isn't new, it is a
With VMWare at least on Windows there's a special ip address one has to use.

Sage-3.1.1 and TeXmacs-1.0.7 used:

[2, 9, 4, 1]
Now is there an easy way to take this list and get back the integer
1492?

I'm not sure if there is a single function that does it, but you can
use the following one liner which
def from_digits(lis):
return ZZ(''.join([str(i) for i in lis[::-1]]))

This launches jmol, and one is able to rotate the shape. One can also
save the image and then import the saved image into Texmacs
sage: var('x,y')
sage: plot3d(sin(x*y),(x,-1,1),(y,-1,1)).show(viewer='tachyon')
launches a viewer
Thanks to both Dan and William. However, Dan's result puzzled me.
Aren't they suggested that the for loop is faster?
Here is what I got:
sage: timeit('list(2*vector([random() for j in range(10)]))')
625 loops, best of 3: 332 µs per loop
sage: timeit('[2*random() for j in range(10)]')
125 loops,
28 matches
