    This is just a test

    Under "my account" there seems to be no easy way of listing all of my recent posts (of all types). There's only an option to list recent blogs. Most of my content are either forum posts or stories as proper blogs are not one of the default content options that I'm given. T4.

    I find the font/colour combinations make posts a bit hard to read sometimes.
    1. The title colour for comments and times is a light grey, while the colour of comment text is a darker grey. These can be hard to read against a white background. With occasional exceptions, non-coloured text against a white background should be black for maximum contrast.
    2. Distinct comments should be visually separated from each other somehow, either by a horizontal bar or by using a different background colour for comment headers. (The latter is what is done, for example on Slashdot).
    Presently, any links outside of the Maple Primes site open in the same window. Would it be possible to have the external links open in a different windows. This way once done viewing the external link the window can be closed and there is still a Maple Primes session window open. Presenly, one must backspace out of the external site to get back to Maple Primes. Any thoughts on this? JB
    According to the information on message formatting, all posts are formatted using HTML tags. This will prove problematic for people posting snippets of Maple input, which is likely to happen often. For example: ========================================================= > p := piecewise(x
    This post is primarily a test of attaching pictures and documents within the environment. If this works, you should see a photo of the view from our rental apartment during my family's recent holiday in Tuscany, and you should be able to access a Maple document via the attachment. Any problems in viewing or detaching, contact me. Any questions on the apartment, see
    The XML icon for the site's RSS feed appears on the left-hand side of the screen, and the feed works when I add it manually as a Live Bookmark in Mozilla Firefox. So the site is certainly capable of RSS feeds. However, I think the convention is that sites with RSS should also advertise this fact by adding metadata to the page header, which MaplePrimes doesn't yet do. An example of this metadata is: <link rel="alternate" type="application/rss+xml" title="RSS 2.0" href="" /> <link rel="alternate" type="text/xml" title="RSS .92" href="" />
    I'm not sure what the snail-mail addresses are going to be used for. In any case, if they're going to be requested, it would be helpful to include a field for province/state information there. We currently have just "City" and "Country". As it is, there isn't enough information to create a mailing address from what's provided. (There's actually a Waterloo, Quebec, as I'm reminded of every time I go to site.)
    Might it make better sense to have the 'Home' and 'About' site navigation tabs in the top right of the page to be reversed?
    It would be nice if the site could remember the login information, so that we don't have to log in every time.
    In some applications it is necessary to map an angle to a range of 0 to 360 degrees. Adding 360 degrees to an angle, or subtracting 360 from an angle does not change actually change the angle. One way to do this would be to add (or subtract) enough multiples of 360 degrees until the angle falls between 0 and 360. For example, given an angle of 400 you would subtract 360 to get an angle of 40 degrees. In Maple, this is easily accomplished by the following function.

    Frem := (x,y) -> x - y*floor(x/y);

    Yesterday, I was in a Maplesoft management meeting where we concluded that the launch of MaplePrimes was to become the number one (or maybe two) priority for the company. So here it is ...
