[sage-devel] Cremona's database of elliptic curves over rationals : compilation?
Hi, I'm considering packaging this database for Debian. I have upstream files: https://github.com/JohnCremona/ecdata I know sagemath wants a cremona.db sqlite3 database, as that's what is in the src/ for the pkg. What I miss is the file turning the data files into the database! For the smaller database, there is: https://git.sagemath.org/sage.git/tree/build/pkgs/elliptic_curves/spkg-install.py But as far as I can tell the two databases don't even have the same format: https://git.sagemath.org/sage.git/tree/src/sage/databases/cremona.py Can someone lend a hand?

Re: [sage-devel] Cremona's database of elliptic curves over rationals : compilation?
The code to create the database is in Sage itself. See https://github.com/sagemath/sage/blob/master/src/sage/databases/cremona.py. I recommend that you hold off for a short while since I am about to update the database to include all conductors up to 50 (now it is 40). This is thanks to Andrew Sutherland + Simon Foundation + Google CP, which ran 80,000 simultaneous jobs on 600,000 cores last night. So right now I am drowning in data but it will all be sorted before long.

I can still try to prepare the package with the old data, and only upload to Debian when the new data is there. Thanks!

[sage-devel] sage-days 104: arithmetic dynamics
We are pleased to announce a sage-days workshop November 17-20, 2019 at Saint Louis University in Saint Louis MO, USA. The main focus is on functionality associated to the arithmetic of dynamical systems and related areas. We are fortunate to have funding via the National Science Foundation programs in Computational Mathematics and CDS&E for travel and local lodging for a limited number of participants. The main workshop website can be found at https://wiki.sagemath.org/days104. Requests for funding are made through the registration form on the workshop website. Those not requesting funding should still register so that we can have an estimate on number of participants for planning purposes. Information on arithmetic and complex dynamics in Sage can be found at https://wiki.sagemath.org/dynamics/ArithmeticAndComplex. The official topic of the workshop is the arithmetic of dynamical systems. Anybody willing to learn or develop Sage is also welcome. As with most Sage-days workshops, the program will be elaborated on the first day of the workshop and adapted along the week. There will be tutorials, short specialized topics, and participant presentations, but most of the time will be dedicated to actual programming with the help of experience Sage developers. If you have any further questions, please contact any one of the organizers. Sincerely, Paul Fili Oklahoma State University paul.fili (at) okstate (dot) edu Benjamin Hutz Saint Louis University benjamin.hutz (at) slu (dot) edu Adam Towsley Rocherster Institute of Technology adtsma (at) rit (dot) edu -- You received this message because you are subscribed to the Google Groups "sage-devel" group.
