I use the Sage Notebook on my server with Sage v.7.4. And each time I try to
open some TXT file in the DATA folder I get the error message in the web
interface

And in the terminal where I started the Sage server, I see this error message:

I have the following problem, and I do not know whether it is a bug
or a supposed behaviour.
I upload a C program to my worksheet and compile it using the
server's GCC with this command:
os.system("cd "+DATA+" && gcc infinite_cycle.c -o infinite_cycle.bin")
Than I start the obtained

Hello!
I'm working with some data arrays which have 'NaN's somewhere inside
them. So I have a couple of questions on how to deal with such arrays.
First, how does the 'mean()' function treats the 'NaN' values in the
lists passed to it? Should it just ignore them and calculate the
average valu

I have noticed a strange unpredictable behaviour of the "plot"

Here is the situation:
I have a data set in the following form:

of Sage. Here is the problem:
I have a list of tuples of the following format:

plot2 = plot(cos, xmin=0, xmax=8*pi)

Hello!
I upgraded Sage to version 4.7.2 a couple of days ago and today I
noticed a strange behaviour of "graphics_array". It shows only the last
element of the array correctly (with a correct size) while all the
previous plots are too small.
Here is a screenshot of what it looks like:

Hello guys!
Could you please explain me (and perhaps some of the other readers)
the reasons (or advantages) of using implicit multiplication at all?
I mean in what situations it could be useful?

Hello!
It looks like this problem is still there. Or maybe someone knows a

My situation is as follows: I have a single .sws file with the size
about 20 MB and I cannot upload it onto any Sage Notebook servers I
know including my own laptop.
