I suppose this topic has come across many peoples minds at one time or another and I've only taken this number for granted and with a grain of salt.  I have become curious as to what other Maple users would run the memory usage up to? 

For myself I find on average usually running below 10Mb or so.  I suppose this is average, for me, but I haven't usually created large worksheets, I don't think I've ever let it run over 40Mb. ...

Here is yet another finesse (new to me) in getting better performance for some floating-point computation involving the Statistics package.

Scrolling through the search results on tags - like "bug" or "mapleprimes" gives an error "file not found", if trying to go beyond page 1

The old subsciptions are trashed, unfortunately.

But how about new ones? It seems I only can subscribe to my own replies, but not to a thread I want to follow or look at it later (for example when this board allows to save threads locally in a convenient way).

Do I miss the solution or is it true?

Saving a 3D object computed in Maple.  Maple itself has only limited capabilities for this.

There is a Maple library called JavaViewLib that sends the data from Maple to a Java applet called JavaView.

From there it can be viewed and saved in many different formats.

Find all the info at www.javaview.de

The last web page update was 2006, but the server that provides the free licenses is still running.

Mostly JavaViewLib...

I have noticed that editing in Maple 14 in document mode becomes very sluggish if the Greek palette is left expanded while editing.  I also seem to see a refresh of the palette (maybe a very quick flash) at this time also.

Editing seems to return to normal if the palette is closed.

I am just curious if anyone else has observed this behavour.

Frank

Some Posts and Questions contain broken links to files uploaded in the "old Mapleprimes". We've heard that some files (eg. image files) may be irretrievably gone.

But here is a curious page. It had an associated .mw worksheet uploaded. And the link to the uploaded .mw is now broken/stale, at the moment that I write this. But the link to view it with the maplenet viewer, in one's browser, still works. Not only that, but the .mw worksheet can be saved from within that viewer (via a URL distinct from the broken link on the Post).

The MRB constant is the upper limit point of the sequence of partial sums defined by s(n)= .

Each summand is a real number. However, the function f(n)= is a complex-valued function of a real number, n. This blog is a break in progression of the MRB constant series for the purpose of looking at the "complex" nature of this function. The function can be written in exponential form, .

With this first post I would like to demonstrate, in a Maple document, what happens to f [-2,0). When put together (-1,0) these graphs seem to be describing a hyperbolic spiral. I'm not sure if I'll have more to say, or not. As always, others are welcome to join in.

A recent announcement: ViennaCL, an OpenCL (GPU) based linear algebra library.

It would be interesting to see how it might be used from within Maple via external_calling (even if only for some simple examples).

Are the following paragraphs from the new Mapleprimes Style Guide supposed to contain marked up 2DMath or interpreted Maple result, because right now they don't.

See http://www.mapleprimes.com/help/styleguide

"For example, if you enter <maple>x^2/y^2</maple> you will get this image: x^2/y^2

Any Maple syntax will appear, so you can get complicated and enter this: <maple>sum(cos(x^2)/sin(exp(y)),x=1..infinity)</maple>
which then appears as this image: sum...

When trying to access beyond the first page of results for a given tag I get a 404 page-not-found error.

An important part of the new MaplePrimes is the reputation system. Reputation gives users access to different features of the site, and is also a quick way for people to get a better idea of how knowledgeable a users might be about Maple.

Since MaplePrimes has been around since 2004, it is important to preserve all of the reputation that our long-time users have built up. There wasn't any method for voting posts before, so we can't use the same algorithm as we'll use going forward. So we came up with a new method using comments to signify an up-vote.

The algorithm is very simple. For every post, question, or answer that you posted on the old Primes, for every comment that is added to your item, you receive 4 reputation points. Also, using the same limit we'll use in the future, you are limited to gaining 200 reputation points in a single day.

We find that this algorithm has done a great job of exposing the top MaplePrimes users as you can see on the top users list. Over time as people start up-voting posts, questions and answers, the reputation scores will continue to grow, and this method for calculating the back-reputation will become less meaningful as the reputation gained from up-votes will overpower the initial reputation that legacy users received from the back-reputation.

It seems to me that the page on Unanswered Questions contains questions which are actually already answered.

An example is Sorting a list of xy pairs, on which one I spend some time yesterday preparing an answer, until I discovered that it had already been answered (one of the answers being completely analogous to the one I had prepared).
