From a Maple perspective: I first started using it in 1985 (it was Maple 4.0, but I still have a Maple 3.3 manual!). Worked as a Maple tutor in 1987. Joined the company in 1991 as the sole GUI developer and wrote the first Windows version of Maple (for Windows 3.0). Founded the Math group in 1992. Worked remotely from France (still in Math, hosted by the ALGO project) from fall 1993 to summer 1996 where I did my PhD in complex dynamics in Orsay. Soon after I returned to Ontario, I became the Manager of the Math Group, which I grew from 2 people to 12 in 2.5 years. Got "promoted" into project management (for Maple 6, the last of the releases which allowed a lot of backward incompatibilities, aka the last time that design mistakes from the past were allowed to be fixed), and then moved on to an ill-fated web project (it was 1999 after all). After that, worked on coordinating the output from the (many!) research labs Maplesoft then worked with, as well as some Maple design and coding (inert form, the box model for Maplets, some aspects of MathML, context menus, a prototype compiler, and more), as well as some of the initial work on MapleNet. In 2002, an opportunity came up for a faculty position, which I took. After many years of being confronted with Maple weaknesses, I got a number of ideas of how I would go about 'doing better' -- but these ideas required a radical change of architecture, which I could not do within Maplesoft. I have been working on producing a 'better' system ever since.

Multiple definite integral change of var...

Some time ago I was asked the question: do you know how to do a change of variables in a multi-dimensional definite integral?  I thought I knew, but I was wrong.  I only know how to do a change of variable in a multi-dimensional indefinite integral. 

This question really intrigued me.  Of course, this is such an obvious question, I just started pulling out textbook after textbook off my bookshelf, expecting to find the answer...

For a bit of light relief, head on over to the online comic strip at phdcomics.com.  If you've ever been a PhD student, be careful, this strip might make the nightmares come back...

I frequently see references to data being loaded from maplesoft.112.2o7.net -- what is that?  It's annoying because the page seems to have been loaded, but the browser is still active doing stuff, so that interaction is slower.  If this is not doing something really useful, could it be turned off?

The New York Times has a really interesting article ``They criticized Vista.  And they should know.'' (you might need to register to see the article, I am not sure).  It shows why Vista isn't really an upgrade to XP, mostly through emails between senior Microsoft executives.  Basically, they knew it was a dud, and instead of going with the more honest approach they were at first planning, went with really misleading advertizing that made things much worse.

A search I was doing dug up this old gem, involving a discussion between Gerald Edgar and I over a Maple problem 16 years ago!

Easy challenge: improve on my solution to Gerald's problem.

History challenge: my email address shows as wmsical!jjcarett@watmath.waterloo.edu.  Can you puzzle that out?  That is really two questions, a) how is that an email address and b) what is 'wmsical' ?
