Software for rational homotopy theory
Did you ask Yves Felix or Pascal? I have heard rumors of a probably like this written in C. Don

Why didn't Vladimir Arnold get the Fields Medal in 1974?
It seems like many of the comments about being passed by are from Arnold himself.

What does the classifying space of a category classify?
I don't know the paper of Michael Weiss, however when I was writing the title of this question I had the feeling I have read this title before. So probably I at least read the title of that paper.

When is every “solid” perfect complex faithful?
Doesn't (4) give an equivalent condition? ie $E$ is solid if and only if for every $f$, $f\otimes E=0$ implies that for some $n$, $f^{\otimes n}=0$. (The converse direction follows since $E\otimes k(p)\not=0$.)

Hamiltonian circle actions and Lefschetz pencils
I guess there are some dimension restrictions that make my last suggestion not possible in general.

Hamiltonian circle actions and Lefschetz pencils
Is it possible to do (3) fiberwise over the image of the moment map? So basically constructing the Lefschetz pencil on each symplectic reduction in a way that only changes a "little bit" as you change the values of the moment map. (I wasn't sure if this comment is appropriate for MO or if I should have written you personally.)

Thanks for your response. I guess it's possible to come up with examples using toric manifolds and various projections of polytopes onto intervals, but this is not something I really know about.
