Hi, I allowed to save pup-431.sfs as well as a pupsave*.2fs and now booting (just the default) works well and because I did in /etc/keyboard (or so) the US-keyboard, that is OK too now ;-) A problem is the WLAN , it sees it,seems to get an IP, but the encryption key (router says: WPA-PSK) and

[sage-support] Using CRT to speed up calculations over QQ

Sage Folks, I am working on a problem that requires me to generate a large matrix over QQ, and then calculate the row-echelon form. I think there's a good chance I can speed up the calculations if I use the Chinese Remainder Theorem to translate rationals into equivalent vectors of small

Burcin, Thanks - I never before saw the multimodular argument. That's really nice, and I like that fact that the default is to pick something suitable. But simply using the multimodular approach when echelonizing the matrix isn't enough. I have to do two steps - first, generate the matrix, and

Hi, Is it possible to compute in Sage a lazy power series y in x satisfying y = x/(1-y) ? I know a recursive definition is possible in Sage lazy power series module. What about the inverse 1/(1-y)? Thank you in advance. Kwankyu -- To post to this group, send email to
