Re: [sage-support] Right way to kill notebook server on single-user machine

I'm a relatively new Sage user, trying Jupyter for the first time.  OS 
is Ubuntu 14.04; Sage version is 8.1.  Starting Jupyter from the 
command line (sage -n jupyter) works as expected, but so far as I can 
tell the only way to shut down the notebook server after closing the 
browser is via ctrl-c.  What if sage is not started from a terminal? 
 Or if stdout is redirected to a file?  For example, if I redirect 
stdout when starting sage, then send ctrl-c after closing the browser, 
the sage-notebook process continues to run -- presumably because I 
have no way to send a second ctrl-c.


I found this 10-year-old post asking essentially the same question:
https://groups.google.com/forum/#!newtopic/sage-support/sage-support/IrA6obQupKw
but parts of it are clearly out of date.  However, the suggestion to 
use "kill -2" sounds promising, but on which process?  I only see two, 
one running sage-notebook, the other running sage-cleaner.  Or is 
there some other way?  "killall python" works, but presumably isn't a 
clean shutdown -- and I certainly wouldn't want to script such a 
sledgehammer.


It would be really nice if there were a provided script for shutting 
down the notebook server cleanly!

Re: [sage-support] scalar restriction in extension field

[Dima Pasechnik]

most probably it had to do with Python's int becoming long int (ones displayed 
with L at the end by the usual Python shell)
