By the way, I also lose the formatting if I click on Edit, and then Save changes. If I just close the browser window and then re-open the still running notebook in a new browser window, all the previously evaluated cells still show up alright (Times with proper line breaks). Only if I quit the worksheet or edit its text version are the line breaks lost and the font turns into Courier. Hope this helps to track it down.

[sage-support] Is readline a prerequisite to build Sage?

Well, you should take it as a compliment: me having high expactations from what I've already seen in the software :-) I am really impressed with the software and it is a great help when doing my thesis on Pairing based crypto here at DTU in Denmark. I've implemented the Weil pairing and just yesterday with the help from Justin and David made an example MOV reduction work. It's a lot easier than having to implement it in C and figure out all the packages for doing finite field arithmetic and having to implement the EC arithmetic on top of that my self.

The problem is that when you do the string formatting, feeding in %delW, what gets passed in is the string representation of delW, not the latex representation. For example, sage: repr([x^(3/2)]) '[x^(3/2)]' You shouldn't expect the default string representation to be latex syntax.

[sage-support] Questions about Matrices and Solving Linear Systems
Hi! I have some questions about matrices and solving linear systems of equations. These issues arose out of my using Sage for examples in my Linear Optimization class (it's great for demonstrating how the simplex algorithm works!) and for research I'm doing involving finite fields. If I have a matrix A defined over some finite field, and a vector b over the same finite field, what's the easiest way to solve the equation Ax=b? Is there any easy way to augment A with b as an extra column? Is there an easy way to insert a row or column? Is there an easy way to delete a row or column? The same questions apply for matrices over the rationals. The functions stack() and insert_row() are pretty useful, but they seem to be only defined for matrices over the integers.
