[sage-devel] Some quick git tips

Hey guys: I was wondering... So, I have my local install of Sage 7.1 from source. I didn't get the source using git, I downloaded it from the website. I've made a local repository for Sage on my computer, and also made a remote repository for it on my github. However, I don't think it is

Then making it Expression.laurent_polynomial() but allowing polynomial with ring=LaurentPolyRing as argument seems to be the best interface. On Wed, May 11, 2016, 22:26 Nils Bruin wrote: > On Tuesday, May 10, 2016 at 10:55:20 PM UTC-7, Ralf Stephan wrote: >> >> On Tuesday, May

Sorry, forgot to mention: all this is happening under Sage 7.0. Under 7.1 it is much worse, I get a silent "Memory exhausted" crash the FIRST time round, without a report. So it seems something really broke between 7.0 and 7.1. -- You received this message because you are subscribed to the

[sage-devel] memory management issue: deleted variables not released

When I invoke a function like BIG=myfunction(somevars) where BIG gets to ~50% of RAM in a concrete case, re-running that function again results in a memory error. If I release BIG first, say put BIG=0, then it works. However, looking at top, I can see that only about half of the memory

It will be great to have axes labels on 3d plots ! Good luck for your ticket ! Eric. -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To unsubscribe from this group and stop receiving emails from it, send an email to

Dear Brian, Appears it is some flavor of Ubuntu Linux running within Windows? https://blogs.windows.com/buildingapps/2016/03/30/run-bash-on-ubuntu-on-windows/ I hadn't heard. ;-) Rob -- You received this message because you are subscribed to the Google Groups "sage-devel" group. To
