Hi Zach and Masoud,

Thanks for the suggestions! I tried fix_mac_sage and this worked perfectly.

Best,

Jack

Re: [sage-devel] Re: Build issue for wheel for scipy OS X Catalina

[Masoud Soroush]

Jack,

I had the same problem. Suggested by Nathan Dunfield, I followed the steps
in https://github.com/3-manifolds/fix_mac_sage, and Sage is now working in
the Jupyter environment on my mac. I believe this solution is the same as
the first option of Zachary's response.

zulip.sagemath.org used to point to a google virtual machine.  We'd like it
to redirect to sagemath.zulipchat.org so that people looking for the Zulip

[sage-devel] Re: Build issue for wheel for scipy OS X Catalina

[Zachary Scherr]

Maybe somebody with more experience can answer, but the problem is likely 
caused by the fact that you used a prebuilt binary of sage and then tried 
to remake it on your own computer.  What tends to happen in this situation 
is that the prebuilt binary was built with a specific version of Xcode but 
then in the meantime Xcode is updated and when you try to remake sage it 
breaks because it's retained paths to libraries that have been changed by 
Xcode updates.

There are a few different options for installing Sage on Mac and getting it 
to work.

1.  Install it through homebrew cask and then apply the fix for ssl 
at https://github.com/3-manifolds/fix_mac_sage.  I have not personally 
tried this but I've seen others in this forum have success.

2.  Install it through anaconda.  This is currently my favorite approach 
since it is simple, fast, and everything just seems to work.  Directions 
are at https://doc.sagemath.org/html/en/installation/conda.html

3.  Install from source.  You can get directions 
from https://doc.sagemath.org/html/en/installation/source.html.  The basic 
workflow after you've extracted the archive would be to run:

>>> source .homebrew-build-env
>>> ./configure
>>> make -jNUM

   where NUM is the number of parallel processes you want to use in your 
build process.

Great, thanks.
OK, the VM is shut down now. I have not yet deleted the VM, but will
do, once we are happy that everything is properly saved etc.

It took me longer than I wanted, but I've ported over all of our history
and accounts to sagemath.zulipchat.com.  For security reasons the passwords
haven't been migrated, so you'll need to use the password reset link (let
me know if you don't remember what email you used).

I've been struggling with the google cloud interface and can't figure out
how to shut down the VM that was running Zulip.  Dima, since you started
the thread about costs, do you know how to do this?  Anyone else?

As for the url, I assume it should be possible to set up a redirect, but I
don't have easy access to our DNS records.

Re: [sage-devel] Re: "Real Field" -> "Real Floating-point Field"

[Michael Jung]

Hi,
so, what's the punch line now? I totally lost track because we digressed 
too much. Is the representation change still wanted or not? And if so, what 
shall be it? I would like to conclude 
https://trac.sagemath.org/ticket/24523.

Best,
Michael
