Re: [sage-devel] Re: Help needed with adding user packages as optional/experimental packages

[Vincent Delecroix]

Great!

Should they be removed from the wiki?
(https://wiki.sagemath.org/SageMathExternalPackages)
The list of "official" user packages are now part of the sage
documentation. We could keep the wiki for the not yet integrated
user packages.

In this case, it might also be good to instead (or also) verify the 
certificate through tests. That way to get to further illustrate your code 
and it is a less brittle doctest.

It depends on whether it is ready on time. The API changed, hence the
Sage interface has to be updated.

Any help welcome.

Re: [sage-devel] Re: sorting output dicts in doctests

[Samuel Lelievre]

Another option might be to use an OrderedDict.

If I understand correctly, this becomes unnecessary
in Python >= 3.7 where dict behaves like OrderedDict.

If I understand correctly, Sage 9.3 will still support
Python 3.6 but Sage 9.4 probably won't, after

[sage-devel] Re: [GSoC Mentors Announce] Now Accepting GSoC 2021 Mentoring Organization Applications until Feb 19

[Harald Schilly]

Hi, a word from my side: I would really like to stop being admin as well 
and hope someone else can take over. I'm the one writing the application 
each year and I could this time around, but in general I want to focus on 
other things after all those years.

Despite that, looks like there are only two mentors. Feels like this is 
below the threshold where it makes sense to pursue this? Maybe we should 
pass this year and re-evaluate for the next one?

I'll be happy to mentor a good student, but would prefer not to be admin.
I already have a huge load of administrative work daily and would 
appreciate not to have extra.
