to the early implementation in 2006!). If anybody contests the fact
that it should return the matrix whose entries are the absolute value
of the initial matrix, please tell me.

Well, the Sage convention seems to be to generalise ArithmeticError to
include undefined mathematical operations, like factor(0). Of course,

step toward localizing the cloud, or Sage proper, etc.
I would love to do Hindi and Punjabi translations(Indian Languages).

Its not permitted by Apple. Whether it is legally enforceable depends on
the jurisdiction. In Germany the Apple EULA is most likely not legally
binding.

Helloo everybody !
I am preparing some Sage talk, and I wanted to say at some point: Honestly
we are not that good. We have strong points but we miss many things too. It
all depends on what the developpers are interested in: we are great on some
research areas, and under water level on others
Weird to answer your own thread, but I think that we are bad for plots.
Look at that:
sage: graphs.RandomTree(40).show()
sage: graphs.RandomTree(40).show(method=js)
The first one is a picture, the second uses d3.js. You can do a lot of
crazy things with it, and it is done in javascript:
