I used to have Maple 10.02 running on Fedora Core 4. I recently upgraded to Fedora Core 5, and 10.02 no longer runs (no error is given). I can't install Maple 10 off the CD or the downloaded 10.03.

Let A be an n by n (0,1)-matrix. How draw the graph of the adjacecy matrix A?

Do you think that it's possible for Maple to ever be free software? I
suppose I should emphasise that this is "free as in freedom",
regardless of whether Maplesoft decides to keep charging money for its
use or not. Me, I don't see it happening in the near future, but I
harbour hope that it could happen for the following reasons:

1) Other success stories of free software, such as the Firefox
browser.

2) Maple, unlike the other leading brand, was built in a purely
academic environment by a community of mathematicians and
scientists who understand the need for free and open collaboration

server: efnet channel: #maple this channel is unaffiliated with maplesoft. It is new at the time of this posting so be patient if there is not much activity at first. I know a bit about maple and may be available to help people with it. If you have never used IRC before it is not difficult. You may want to read about it a little by googleing IRC. if you just want to connect I have posted instructions about connecting to this and other math related channels on IRC at this link: http://web.mac.com/luther_driggers/iWeb/SFUMSU/NEWS/50430B9A-5AAD-48DC-B53B-A5565C352F70.html

When I click the "blogs" tab at the top, I do not get a list of blogs, but only "Bratva's blog" (in Cyrillic). Needs a fix...

Just announced. Performance imnprovements for start-up and equation editor improvements are some of the improvements. Download 10.03 patch here. T4.

MacTutor archive by John O'Conner and Edmund Robertson, is a very thorough database of biographies, chronologies, etc. It convers ancients to contemporary. There is an immense amount of information and you can easily get lost in this site.

M. Mahaswaran's Catalog of Mathematics Resources on the WWW and the Internet ia a very complete list of useful Math links (the most complete I've ever seen).

I'm not quite sure where this should go. I'll post it in MaplePrimes suggestions for now, and move it elsewhere (MapleNet, MapleTA, ...?) if others feel that would be advisable. I have uploaded a Maple 10 worksheet that implements the Hill Substitution Cypher for encoding messages. The worksheet uses embedded components to create what amounts to a Maple syntax-free interface. Here are two views of the worksheet. First, the worksheet 178_HillSubstCipher.mw on MapleNET. And, second, to download 178_HillSubstCipher.mw.

Hi. Hope someone can help me. I have attached a file, created in Maple 10.02 (the Java version). The file seems to be corrupted, since every time i try to open it, I get the following error message: "File open!" "There were problems during the load process. Your worksheet may be incomplete." No input or output is displayed in maple, eventhough the fileize is 552KB. I tried then to open the file with classic worksheet maple 10 and the console, and with both the Java and classic worksheet version of Maple 9.5, still to no avail. If i open the worksheet in notepad or similar, I can tell that the code is still existing.

Hi to all I have a .dat file and the few first lines are: 2006-03-22 00:00:00 N=32.90 N=0 N=35.89 N=3 N=56.00 N=0 I want to remove the first line and the N= of the next lines to get only the datas, i.e. 32.90 0 35.89 3 56.00 0 How to do it? Thanks for your help de Pierre VE2PID
