[sage-support] roots over QQbar for polynomial over number field

I feel like I should know the answer to this... I'm trying to get the roots of a polynomial f over an algebraic closure. Over the rationals this is quite easy, you simply call f.roots(QQbar). However, if the polynomial is defined over a number field already, this results in a TypeError: Illegal

[sage-support] colors in 6.5

I've noticed that in 6.5 my terminal colors went back to the default (LightBG), i.e., it seems to ignore the line c.TerminalInteractiveShell.colors = 'Linux' in my $SAGEROOT/ipython-2.3.0/profile_default/ipython_config.py. (Running 6.4.1, still installed, gives me the correct colors.) Does a

[sage-support] first order ODE oddity

Hello, I'm puzzled about sage: var('a,t') sage: y = function('y')(t) sage: desolve(diff(y,t)-(2*t*y-6/t-6/t^3), y).simplify_full() _C*e^(t^2) - 3*Ei(-t^2)*e^(t^2) + 3*e^(t^2)*gamma(-1, t^2) because c*e^(t^2)+3/t^2 is (also?) a solution to this ODE according to Wolfram. So, is the second solution
