If one sets up a Sage server for public use, there is the opportunity for
someone to publish worksheets, there is a section:
"Browse published Sage worksheets
(no login required)"
But often those worksheets are bad examples, error message, or just plain people
experimenting. I do not think they generally reflect well on Sage.
Hence I'd propose that there was a collection of worksheets that always appeared
at the top, with sensible names and good examples. Then let the other published
worksheets be shown below.
Either that, or perhaps make it clear that anyone can edit these worksheets, and
so many not represent how best to use Sage.
One normally associates "published" work as being of high quality. But in this
case the "published" can be anything. Whilst regular users of Sage will know
what this means, for someone taking a quick glance, they are likely to get the
wrong impression.
I strongly agree! I remember taking the bad impression you described
when I first saw the published worksheets on sagenb.org .
I'm glad I'm not the only one to feel this.
I don't
think a rating system would work since there is already one, and it
rarely gets used, sometimes good worksheets get bad rankings and vice
versa. I think it would be best if people would just submit proposed
worksheets for inclusion in the *good* category.
Yes, agreed.
Jaap Spies sent me a screen shot some time back, when I first set up a Sage
server on my own SPARC machine. I thought it was pretty impressive, so took his
code and published it on the server running on 't2'.

But there is also a published document which shows an error message, which has
since been resolved
http://t2nb.math.washington.edu:8000/home/pub/1/
so that does not give a good impression (This is not aimed at a dig at Robert
who published it. He was trying to show me a problem. It's just an example of
the sort of things that get "published" )
I further propose that some of these get included in new Sage notebook
installs, so that people new to the notebook can inmediately click on
already made notebooks and get some nice code that works.
Yes, I think 30+ decent examples. Hopefully some where you do not need a degree
in maths to know what they are about.
I'm not a mathematician, but have an engineering background. When I look at the
introductory examples for Mathematica, most are easily understood - graphs
plotting, factorization, integration, differentiation, numerical methods,
finding roots, curve fitting to data, etc.
I think there is a bit too much emphasis of the examples of things only
understandable by those with a very good maths background. I've never before
come across the term "ring". To be a viable alternative to the Mathematica at
least, there needs to be more examples of usage by non-mathematicians.
