Sage Introduction

[Owen Densmore]

I beamed into the sagemath.org site and noticed they had video tutorials.

I watched a brief (10 minute) video and followed along building a Sage worksheet.  Here's what part of it looks like:

Playing about a bit more, I figured out how to "publish" the worksheet:

http://www.sagenb.org/home/pub/3032/

There is a shared account with login/pw friam group.  I think you can edit and play in the "live" version of the worksheet:

http://www.sagenb.org/home/backspaces/4/

Don't worry if something goes wrong, I've go the original on my laptop.

You can also beam into friam/group and make new worksheets to play with.

Any obvious advantages over Google Docs Spreadsheet?  In fact, since one can't upload an .XML file, it seems Sage is going out of its way to make things hard.

Well, as much as it may look like an application, Sage really is an IDE for Python + All the existing open source math packages.

So for looking at a spreadsheet, the numpy package has an importer that does a great job of CSV's.  After loading the CSV as an array, you can do a LOT with it.

Is this what you mean?

Maybe that's what I mean.  If your spreadsheets are not large, and the analysis is basic, then Google Docs works OK.  But the .XML format is today such a standard (for the real world) that I'm surprised that it is not includes in the import choices.  Yeah, you can save Excel as CSV, but is it worth going that extra mile?
