Re: [sage-support] for those who can appreciate

2023-05-24 Thread Henri Girard 
I forget to say : I have done it with the windows version installers 9.2 
and I compiled sage-10-1 dev because on ubuntu (sage-dev 10.1 compiled 
but not 10.0 a problem with giac on wsl2), which is a good proof of the 
facility to get sage working !

Right now on https://www.phind.com/ if you click on "Use Best Model 
(slow)" and include "using sagemath" in your question,
it will combine the sagemath docs, web searches, and GPT-4 to answer 
your question.  This might result in better answers
in some cases than just using chatgpt.   I don't know how long 
https://www.phind.com will be free or if it is globally available

or what, but it is fun to play with right now.

2023-05-24 Thread Henri Girard 
Thanks for appreciating and doing it on cocalc ! I will send few others 
I have done all over these  years (since the beginning of sage) with the 
help of the list ! But first I must find them back !


best
