Announcements about MaplePrimes and Maplesoft
So, is there any information about Maple 11, or do we have to wait until the Joint Meeting to find out? Just curious if anyone has found anything out or knows anything about the next version!
We want to know what Waterloo has done about using full 64 bit performance in VISTA and multicore and parallel computing. Pros, please tell us; we want our supercomputer abilities now!
Lambda the Ultimate is a community site for programming languages. The name comes from The Original 'Lambda Papers' by Guy Steele and Gerald Sussman. Yep, that Guy Steele, co-creator of Scheme, then Java, now working on Fortress. Fortress is intended to be a disruptive technology (like Java was), and is squarely aiming at markets that are currently served by Fortran and Matlab.
My daily routine involves a look at what's new in academic Math via the ArXiv (through the convenient Front interface at UC-Davis), and in academic CS via the lesser-known Computing Research Repository. Actually, I use the nice feature both have to have an email (with links) sent to me every weekday with new posts in my areas of interest. recently posted a new user story that describes how Maple was used by a German company that develops, produces, and distributes towing kite wind propulsion systems for modern means of sea travel and transportation.

Here is a quote from the company:

“SkySails is grateful to Maplesoft, because Maple saved us a lot of time. Using Maple was very easy and quick. The computations we used are probably very basic for Maple, but they were extremely effective for SkySails. When testing the simulator, the correctness of the mathematical model is crucial. With Maple, there was nothing to worry about!”

Unforunately, I have had to remove the ability for users to upload HTML files to MaplePrimes. We recently had a user upload 630 HTML files that all had links to their Viagra and Cialis ads. In the 8 months that the File Manager has been available, only one user has uploaded an HTML file, so I doubt that this functionality will be missed. If you need to post HTML to MaplePrimes, you can always just copy and paste its source code into a posting. If you have any comments on this, please add them below.
First, my profile got erased and replaced with some outdated information - like I am working at Tennessee Tech etc. I don't work there anymore (or anywhere else) since June. All my favorite mathematicians/scientists got erased and I have to think again about that and try to recall who was included there. Fortunately, I didn't have this problem with my favorite performance artists etc. - the entry got erased, but I easily restored it. Next, clicking on Dr. produces an empty page titled People who have the title <em>Dr. </em> instead of a list including me and other Drs.
According to the help page ?RandomTools,integer ,
  • By default, the flavor integer describes a random integer in the range -499999999994 .. 499999999994, inclusive.
In reality, Maple produces only positive integers, in the range between 1 and 999999999989,

I just uploaded a small change to the theme of MaplePrimes. Now when you click on any of the tabs on the top right of the page, the red color will stay when you are still visiting a page from that section of the site.

Also, when you click on a link into a section the appropriate tab will become active: Click on a forum post, the forum tab is active, check out a blog entry, the blog tab will be active.

A small change, but it makes the site a bit more attractive.

Maplesoft has just created a new promotion Tell Us Your Story. If you submit a story about how Maple and other products have helped you out, you can win an iPod. Free iPods will be given to three randomly selected people who submit their story here. Here is the text from the page: Has any Maplesoft product helped you? Tell us about it! You could win an iPod! Maplesoft is always looking for great ideas and techniques from our user base. If Maple or any of our other products has helped you work more efficiently, creatively, or just simply better with your mathematics, we want to hear from you.


Update: The contest has ended. Thank you for your submissions.
Answering to Definite Integral post, I tried to do the first example in ?inttrans[fourier],
inttrans[fourier](3/(a^2 + t^2),t,w);

         Pi (exp(a~ w) Heaviside(-w) + exp(-a~ w) Heaviside(w))
       3 ------------------------------------------------------
using int,

No comment. Well, I tried another example from the same help page,
inttrans[fourier](1/(4 - I*t)^(1/3),t,2+w);
A new version of the File Manager was just uploaded. This version now can convert more files to HTML in addition to Maple .mw worksheets. Now if you upload a .txt .mpl, .m, .html, .htm, .maplet, .mm, or .csv file the contents will automatically be converted to HTML. This allows you to view the file directly on MaplePrimes without having to download the file. You can copy the HTML code into your postings, allowing people to see your text files formatted correctly in your postings. When you upload an HTML file, the file's formatting is left intact. But the file's <head> section is removed so that when you paste the file in, it will not cause problems with the formatting of the site.
The links that appear at the top of entry forms have been updated, now when you click on "Upload/Use File or Worksheet", the following text is automatically inserted into your posting: Please replace this text with the link to your file. The link can be found in the File Manager This is to help remind you to copy and paste the link code from the File Manager back into your posting. If you have any comments on this feature, please comment on this post.
