[sage-devel] About solve(x*abs(x)==1, x)
This has been discussed earlier, but I was again asked about this: sage: solve(x*abs(x)==1, x) [x == (1/abs(x))] sage: solve([x*abs(x)==1, x==x], x) [[x == 1]] And yes, to_poly_solve=True can be used. But this is annoying to teach and gives bad impression of Sage. Is there any plans to make this better? -- Jori Mäntysalo
[sage-devel] request to build/test mac-app on OSX 10.13
Could anyone who happens to be using OSX 10.13 check whether mac-app builds and works? We have a recent thread here "Sage 8.1 building Mac-app fails" saying that it apparently fails on OSX 10.13 (but works on 10.12 - the OSX version I can test on ATM) (if you never built it before, note you would need 10-15 Gb of disk space for this) Thanks, Dima -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

It would also be great to get a confirmation that the external libcurl installation was picked up. Namely, somewhere in the output of ./configure there should be a line curl-7.56.1 not installed (configure check) (in the long list of the other Sage packages) - perhaps the version number is different there for you; most probably 7.55.1. If this is indeed this case, you are probably hitting an R bug---indeed, these lines in your log: [r-3.4.2.p0] checking libcurl version ... 7.55.1 [r-3.4.2.p0] checking curl/curl.h usability... yes [r-3.4.2.p0] checking curl/curl.h presence... yes [r-3.4.2.p0] checking for curl/curl.h... yes [r-3.4.2.p0] checking if libcurl is version 7 and >= 7.22.0... no look as if for R the version 7.55.1 is smaller than 7.22.0, which is kind of silly.

If an "admin" is logged in (which is the default solution for local notebooks) it could have a "notebook shutdown" button, but sagenb isn't being developed anymore. -- You received this message because you are subscribed to the Google Groups "sage-devel" group.

[sage-devel] Re: About solve(x*abs(x)==1, x)
how much of Sage are you using? If you are just using Sage as a front end to Maxima, maybe you should just use Maxima. The relationship of solve and to_poly_solve has been discussed from time to time in the maxima newsgroup. Whether there is a feasible "upgrade" to just use sympy's solve is perhaps another path.
