ipython notebook

[John Cremona]

I don't think that I have been paying attention. What is this
"ipython notenook" and is it part of Sage? How does it relate to the
existing notebook? How do I run it?

[Volker Braun]

Its in 6.4.beta6. Run with "sage --notebook=ipython"

It said that pyzmq is missing. Then sage -i pyzmq said that zmq.h was not
found. (And last "yum whatprovides 'zmq.h'" found no matches...). A bug in
pyzmq?

(Might be, again, something wrong with my setup. Don't use much time for
this.)

Did you run "make" after pulling the git branch? The zeromq and pyzmq packages are new and need to be compiled.

I did not. But no help from that:

Ok, its a dependency bug: http://trac.sagemath.org/17202 

Workaround is to run

sage -f zeromq

sage -f pyzmq

sage -f ipython

[Errno 104] Connection reset by peer

I.e. sagemath.org stalled. Mirrors of those somewhere?

I think the mirroring is currently broken either due to the website relayout or the boxen move.

[Jori Mantysalo]

I got ipython to run. Looks nice.

How is account management done with it? Ldap integration?

Currently it is single user only.

the multiuser support is a separate project that wraps the single user component:

https://github.com/jupyter/jupyterhub

Single-user application and multiuser authentication/management are not bundled into one tool as they are in Sage.

Is the first release out yet? In August you said it would be October/November...

[Fernando Perez]

Yup, we're a little behind... :)  Trying to get 3.0 out before the end of the year. The JupyterHub tool is more admin-oriented, so we don't have a release date for it yet: people are using it for now straight out of github, and until we feel that we have an API and model we really like, it will likely continue that way.

So, for an Sage server admin this means that there is no horry to look at
IPython yet? And on the other hand, IPython will come, and there is no
meaning to make big enhancements to sagenb?

For now sagenb works quite well for user viewpoint. As an admin I see
missing features, like really deleting a given user include data, and
deleting accounts that have no local password and ldap does not found use
anymore. Also main page for documentation on sagemath.org does not contain
"Admin's Guide" parallel to "Developer's Guide".

Things seem to be back in order now.

I think the lack of progress on sagenb is much more due to the *simultaneous* existence of the (for now, beta) Jupyter and SMC projects.  Nearly all effort that would have gone to sagenb has gone in those directions - and I'm not criticizing those projects, just recognizing reality.

Please do open issues at the sagenb github site, that would be quite helpful.  Also, it's really interesting to me how many admins have these truly amazing fixes that they haven't shared with the rest of the community because sagenb development has been moribund.  A few of us are trying to fix that, though.

In addition note that there was little [1] progress on sagenb for
years before Jupyter=IPython and SMC existed. This might be because
people who learn about modern web development realize that sagenb was
written/rewritten mostly in 2006-2009 [2], and that web development
technology (both frontend and backend) has progressed dramatically
since then. They might thus not be motivated to work on sagenb.

[1] There was a rewrite of the frontend UI of sagenb, which wasn't
quite released... The last serious work I can remember on sagenb was
Mike Hansen switching it to use flask and that was quite a while ago.

[2] Not only that, but sagenb doesn't even use a database, so it feels
more like it was from the 1990s... (my fault.)

In addition note that there was little [1] progress on sagenb for
years before Jupyter=IPython and SMC existed.  This might be because  

"Year" maybe.  There was no major work, I guess, but Keshav and Jason G. both did quite a bit in 2012, including switching to git and MathJax etc.  But progress really slowed down once Sage cell and SMC took off (I forgot Sage cell earlier).  It probably didn't help that just when it had finally moved from devel/sagenb to code.google.com, then it was moved to github.

 

people who learn about modern web development realize that sagenb was
written/rewritten mostly in 2006-2009 [2], and that web development
technology (both frontend and backend) has progressed dramatically
since then.  They might thus not be motivated to work on sagenb.

That would be outsiders.  I'm talking about people already actively using Sage and sagenb, who would have a motivation for this independent of that.  As many have said, most programming is maintenance...

 

[1] There was a rewrite of the frontend UI of sagenb, which wasn't
quite released...  The last serious work I can remember on sagenb was
Mike Hansen switching it to use flask and that was quite a while ago.

I thought that was also Rado et al., but anyway.

 

[2] Not only that, but sagenb doesn't even use a database, so it feels
more like it was from the 1990s...  (my fault.)

Yeah, the more I look at the code the more I have a feeling that accounts for a lot of its slowness with many users.  But don't worry; sagenb is nowhere NEAR the oldest technology used on our behalf on a daily basis, I'm sure, even if we're not aware of it... e.g. http://jobs.monster.com/v-it-q-cobol-programmer-jobs.aspx

I have tried this ("sage --notebook=ipython") with 6.4.rc0: this works
very nicely, and this is impressive!

I have a question, may be a beginners question: is it possible to use an
existing profile ? I would like to make slides, using the "rise"
profile; so I tried:
sage --notebook=ipython --profile=rise
which gives nothing (it gives the same thing as
"sage --notebook=ipython").

I have verified that: ipython profile=rise works (as explained in
http://nbviewer.ipython.org/github/damianavila/live_reveal/blob/master/Install_RJSE.ipynb).


Yours,
