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.

I rather liked to get updates telling me that a forum I had posted in had been updated, but now I no longer get those.  Did this feature go away, or did I somehow muck up my settings to remove this option?  [I did remove 'aggressive notification', I hope that was not it, as I do want to keep those separate].

Right now, 'jakubi' appears to be online twice -- ie his name shows up twice in the "Who's online"! Even if he is using two computers at once to read mapleprimes twice as fast, this does seem rather weird!
Can someone explain whether this is a bug or is Maple really splitting into 2 languages? In particular, for the input with(Logic); BooleanSimplify(Import(a < b and d = e and not a < bd)); in Maple's document mode or in the TTY version, quite different answers come back. I understand the [weird] reason why the TTY version returns 'false'. The question here is, why the difference?
This morning, I saw the announcement of a paper on the ArXiv, titled Inequalities for Integer and Fractional Parts. I found the results very pretty, even though many of them are rather weird. But then it struck me: this ought to be useful. In fact, it ought to be useful when doing experimental mathematics, something for which Maple is rather helpful. So why the blog post? Because of the next realization: I don't really know how I would 'integrate' this knowledge into Maple. Whatever ideas I come up with to do this seem less than half-baked.

The Vim editor ships with a maple.vim file, which is a "maple mode". It was first created by Charles Campbell, and I provided some updates (up to Maple 9.5). I am about to rev that up to Maple 11, so I would like to know if there are any feature requests which I should consider rolling-in at the same time? If you have little bits of vim scripts which you yourself use, by all means, send them along! [You'll get full credit for that, I am fine with being just an aggregator...
