Re: How to get a heap visualization

Have you gotten in touch with Joachim? I think he's touched that space in
the not too murky past.

That didn't prove helpful in this case. We need to dive down
into the structure of certain large and complex objects to find
out what is happening.

My plan is to see if I can apply the vacuum PR manually locally
and see if I can get it working reasonably soon. If not, I guess
I'll try running ghc-heap-view without visualization and see if I
can make sense of the textual output.

Actually, the profiling was done by someone else, not me.
Now that you mention it, maybe I'll first give that another try
myself and see if I can get any farther.

Still, vacuum-style heap visualization is a really nice tool.
It's a shame that it has fallen into such a state of disrepair.

Thanks,
Yitz

Post-Proceedings THedu'17 Scope:

Computer Theorem Proving is becoming a paradigm as well as a
technological base for a new generation of educational software in
science, technology, engineering and mathematics. The workshop brought
together experts in automated deduction with experts in education in
order to further clarify the shape of the new software generation and
to discuss existing systems. This call is open for everyone,
also those who did not participate in the workshop.

Important Dates (EPTCS Post-Proceedings)

* Call for papers:08 Sep 2017
* Submission (full papers):   17 Nov 2017
* Notification of acceptance: 15 Dec 2017
* Revised papers due: 19 Jan 2018

Topics of interest include:

 - methods of automated deduction applied to checking students' input;
 - methods of automated deduction applied to prove post-conditions
   for particular problem solutions;
 - combinations of deduction and computation enabling systems to
   propose next steps;
 - automated provers specific for dynamic geometry systems;
 - proof and proving in mathematics education.

Submission

  We welcome submission of papers presenting original unpublished work
  which is not been submitted for publication elsewhere.
