So the quitting time is within the last 10 days.

Is the ISC kaput
Yes, the old one at Simon Fraser (oldweb) is OK, but is badly out of date. The address I used is the one in the link in my question... isc.carma.newcastle.edu.au where it moved in 2010.

hypergeometric at nearest singularity
This is a good answer. Evans & Stanton point out that the ${}_2F_1$ case in Luke's book is easier than the ${}_3F_2$ they are doing.

A criterion of norm null sequences in Banach space
More generally, in a metric space, a sequence $x_n$ converges to $y$ if and only if every subsequence of $x_n$ has a subsequence that converges to $y$. For topological space, you can do this with nets instead of sequences.

Is the notation ${}^t g$ for the transpose of a linear transformation intended to be suggestive?
I think the left t is the Bourbaki choice.

“Nice” functions on infinitedimensional space of germs of continuous functions at a point
You say "functionals" and not "linear functionals", right?

Is the sequence of Apéry numbers a Stieltjes moment sequence?
I accepted this answer. But anyone reading should see the other answers, too, to get a full discussion.

Are Banach space norms (up to equivalence) unique?
... of course (as noted by Simon) that unbounded $\phi$ cannot be explicitly constructed. And cannot be constructed at all in simple ZF set theory.

the meaning of “Cauchy filter” for an arbitrary topological group
So, in fact, "Cauchy filter" is not standard in a general topological group. Instead, "left Cauchy" and "right Cauchy" filters are.

How do the compact Hausdorff topologies sit in the lattice of all topologies on a set?
For purposes of bestowing reputation, ask only one question per post. You are more likely to get answers rather than comments.

Another question on Borel sets and projections
Looks like Bob may find a book on descriptive set theory to be of interest.

The Notion of Strong Measurability for Separable Banach Spaces
Yes, in complete measure space, you can redefine your approximations on a set of measure zero.

How to study analytically this ODE?
What do you mean by "analytical"?
