Igor's sliders for 2d plots look good. Some other random notebook
ideas I had (that i don't expect to be implemented anytime soon, but i
think are worth writing down somewhere):
Is it possible to put all output (and input?) cells in some css (html/
whatever, i dont know anything about web
I like 3. It probably makes the most sense because its the behavior is
simplest to define/remember, and (in)equality is by far the most
important anyway.

Some weird behavior in ComplexIntervalField:
CIF(0) != CIF(-1, 1);
This should be false (as the value 0 is contained in both intervals),
but it returns true (using whatever version is on sagenb.org).
A little deeper:
print CIF(0);
0
print CIF(1);

I was interested in seeing the performance differences between MATLAB
and some open source offerings so I googled and came across this:
http://www.sciviews.org/benchmark/index.html
It seems like MATLAB did not have a huge edge in performance over R
when the test was done, but that Octave was far

This is called flamebait, and I am guessing thats why no one has
responded yet. But its been in the back of my mind since I first read
it yesterday, and here is what I have to say...
I just kind of started following SAGE but the most obvious response to
this sort of criticism is to point out
Along the same lines, another nice thing would be keyboard shortcuts.
The most important being Interrupt and Evaluate all. Of course,
we don't want to turn the web browser into an IDE but I think this is
within reason. Perhaps these even exist, as shift+enter evaluates the
current cell (this

python libraries) so that you can jump to that line? I have found
that the code that it spits out is usually very ambiguous (and there

Hello,
I have boiled it down to:
R = RealIntervalField(32);
A.i,j,k=QuaternionAlgebra(R,-1,-1)
print A(1)/(j + 2);
Executing this code results in an error whose traceback is pasted at
the end of this message. Note that by hand (or by using RealField
instead of RealIntervalField) this
