  • One of the more interesting application areas of Maple is in the area of cryptography. A symbolic system's algebraic and integer facilities are great tools in exploring or developing ciphers. Today, I was chatting with a colleague of mine on the topic of ancient computers and at one point, I had expressed my desire to find a replica Enigma machine ... I was promptly introduced to ... Paper Enigma Machine

    There has been active threads on easy ways to post Maple or math specific content - e.g. code snippets, good looking math, plots etc. This Web site will definitely be less effective if people are forced into cumbersome processes to put what most of us would consider to be "fundamental" information into their postings.

    Theory has it that Maple is good at producing HTML code. For the original application that it was intended - i.e. creating self-contained Web pages, it works pretty well. Can this theory be extended to cover our MaplePrimes beta application. How easy is it to use Maple as the authoring environment to express some math and to do a plot and general HTML code that is useful for MaplePrimes? 

    Just out of curiosity, are we actually intending on using the content rating tools, or are they there as part of the default Drupal installation? I ask because the rating boxes (e.g. here) take up a reasonable amount of screen space, and never seem to go away, even after one rates the page. I would expect the rating box to go away or change after I've rated something. At the moment I find the rating boxes distracting, since I'm more interested in the user-provided text.
    Well, I've been working on a units poster for some time now... Okay, so this isn't the same as some of the blogs which are currently posted, but c'est la vie. I recall thinking how close g (= 9.80665) was to π, and only now do I learn that that is more than coincidence. When the French came up with the metre, I guess they wanted something very close to three Parisian feet, and there were at least two possibilities: 1/10 000 000 the distance from the North Pole to the Equator or the length of a pendulum which has a half period of 1 s. As it turned out, they picked the former, but as both were close appropximations to the same standard, it ended up that `≈`(sqrt(g/m), pi/s), and thus, solving for g, we get that `≈`(g, pi^2).

    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.)
