Fwd: [sage-support] Application/Use of Sage in IT company or Industries
hello sage users and developers.one of my friend asked me the following questions.can you please give the sufficient information? I want to ask that what is the use of sage? Why should we use it? Where its being used till date? These questions might be simple and i want to know before i go deep in sage. Please everyone on this mailing list reply that why you use sage? Whatever i think about sage is that sage is helpful for teaching maths. -- To post to this group, send email to sage-support@googlegroups.com To unsubscribe from this group, send email to sage-support+unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-support URL: http://www.sagemath.org

You need to install the build-essentials package and the gfortran package.

For example some maintenance software from your laptop vendor (as the Sony VAIO stuff mentioned on the same page). In fact I would put my money on this because I had the same behavior on my laptop a long time ago and have little chance to have any trojan or malicious stuff on it because the first thing I used to do when I booted into windows was to update it and I never installed anything exotic except for VLC. And I definitely had a bunch of Lenovo crappy software installed by default and which would do plenty of stuff I was not even aware of. You could argue that such software is actually malware.

[sage-support] Re: Sage installation on windows : browser cannot connect
And I think that the port 8000 was dysfunctional because some service
already listened on that port (I don't have the computer at hand anymore so
cannot check...)
as suggested by this result from a simple google query:

[sage-support] Re: Sage installation on windows : browser cannot connect
Today at some Sage meeting in Paris, we encountered this problem once more
with Sage 4.7.2 vbox image within Windows 7.
The image was correctly (or seemingly correctly) preconfigured with 8000 on
the outside pointing toward 8000 on the inside and into 22.
Once more it was possible to ssh from the outside into the inside (using
putty and port as expected).
Nonetheless accessing localhost:8000 or 127.0.0.1:8000 gave a "Not found"
error.
After some random stupid ideas, changing the port forwarding of Virtualbox
to redirect (a random good looking number which has no special reason
to be in use or forbidden) from the outside to 8000 inside the virtual
machine solved the problem!
Don't ask me why Windows 7 does not like the 8000 port... nor why it
preferred the one.
