We have recently more or less revived a SPARC Solaris 11 port of Sagemath.
So yes, please, make it both-endian...

IMHO the fair use of such data is that you contribute something back, if 
you can.   
E.g. the downloader could try to contribute code, or docs, or bugfixes to 
Sagemath, or some other related  open source project ;-)
(e.g. via GSoC, or not...)

Good that you managed to get a working Sage installation!

Dima suggests to post copied and pasted input and output of
a terminal session, rather than screenshots. I agree for two
reasons: text material can be copied and pasted again (while
a screenshot is less useful in that respect), and eats less
storage and bandwidth. Keep that in mind for next time.  : )

OK, so it is fuseblk. Does it mean it's some kind of dual-boot setup, and 
behind the scenes it is NTFS or something like this?

Anyway, you should be able to do your build somewhere on /dev/sda10, ie in 
a subdirectory of `/` which is not under a mounting point of something else.


By the way, there is no need to send us screenshots, it should be perfectly 
possible just to copy the output of the command with the mouse and
paste it into your message.

[sage-support] Request for a large download of data

[John Cremona]

>From the bug-report spreadsheet:

I am a PhD student in Mathematics at Oxford interested in identifying
modular forms given their q expansions. To do this it would be useful to
have a copy of the `webnewforms` collection listed here
https://github.com/LMFDB/lmfdb-inventory/blob/master/db-modularforms2.md.
As far as I can see I can download this this from the readonly MongoDB host
at m0.lmfdb.xyz.

However, before I do it, I just wanted to check that it's ok to make a
large query direct to the database, i.e. not through the website, and that
I won't be violating some kind of (possibly informal) fair use policy.

Thanks,
Alex

One way to do that in the terminal, from the sage-8.1 directory,
is to run the command

sudo ln -s `pwd`/sage /usr/local/bin

After that, from any location, running

sage

will launch Sage.

You can also start other software shipped by Sage. Namely,

sage --gap
sage --gp
sage --ipython
sage --maxima
sage --R
sage --singular

will respectively run the versions of GAP, PARI/GP, IPython,
Maxima, R, Singular, shipped by Sage.

If you then also run this command in the terminal:

sudo sage -c "install_scripts('/usr/local/bin')"

then you will be able to start these other programs directly by:

gap
gp
ipython
maxima
R
Singular

(if these commands already existed in your system, they will
not be overwritten).
