Our firewall attempts to filter downloads (for virus scanning purpose, or
se we are told) more or less transparently : when I use wget, I see a
waitong period with on byte per second, then a fast (Ethernet speed))
download of the target file.

This is indeed odd.

You shouldn't have to do this - let us know if it doesn't plot otherwise.
And the canonical way to do it if you really wanted to is X = Graphics() .
X+=E.base_extend(S[0]).plot(color=red,legend_label=str(exp(1.)))

Dear all,
The new all-shiny all-singing all-dancing fastest mirror selection is
probably useful for large tasks (maybe not so much for small spkgs). I note
however that it is launced once fopr each package/tarball/item that has to
be downloaded, not once per job.
Furthermore, behind some
The timings are cached (assuming that they find a mirror).
The timing is based on an actual connection on port 80, no ICMP involved I
think. If your firewall blocks it then it will also block downloads.

Dear all,
Thanks for the helpful suggestions. I am not sure who wrote the
plotting funtion, but it goes back to the early days of Sage. I have
a feeling that David Roe most recently worked on it, and if so then we
might be able to fix it at the upcoming LMFDB workshop when he, and
Nicolas and I will be

I had just forgotten what I did; the fastest mirror code does not use ICMP.

I am tracking rotation of an object using quaternions by accumulating each
successive rotation using quaternion composition.
I notice that probably due to rounding errors, the norm of each successive
quaternion is drifting from being 1, which means I need to normalize the
quaternion.

I am trying to do image processing in sage but unable to do so. I started

I am puzzled at this:
