Most programs will not produce and assign to a large number of global "top-level" names. But it is interesting that the cost associated with such global name assignment is related to the number of entries in libname.

A possible cause of this cost is the need to check whether the name is protected, before assigning.

The following timings were made on 32bit Maple 15 running on Windows 7, on an Intel i7. The set of four timings is...

SHA-0.3.zip includes a Maple archive and help data base that implement the SHA algorithm (SHA-1, SHA-224, SHA-256, SHA-384, and SHA-512).  The implementation is interpreted Maple, so will be considerably slower than a compiled routine, but these should be fast enough for likely uses in Maple.  For example

CodeTools:-Usage(SHA("The quick brown fox jumps over the lazy dog", 512));
memory used=502.00KiB,...

It may be of interest to this community that the original Maple Project at the University of Waterloo was awarded the ACM SIGSAM Richard Dimick Jenks Memorial Prize in June, at the joint ISSAC/SNC 2011 conference (overlap with FCRC 2011).

See here for the announcement.

In 2010-2011, I persuaded tens of thousands of Russian and Ukrainian students and students in that Maple - a very useful thing.
Testimonials - the number of visits and thanks.
So I decided to resurrect some of my old sites.
Not just for history!

The first: Maple PoverTools.

A worksheet that plots Tupper's Self Referential Formula

The complexplot3d command can color by using (complex) argument for the hue, and compute height z by magnitude. So, when rotated to view the x-y plane straight on, it can provide a nice coloring of the argument of whatever complex-valued expression is being plotted.

Another way to obtain a similar plot is to use densityplot (with appropriate values for its scaletorange option) and apply argument to the expression or function being plotted. For some kinds of complex-valued...

The June edition of the IBM Ponder This website poses the following puzzle:

Assume that cars have a length of two units and that they are parked along the circumference of a circle whose length is 100 units, which is marked as 100 segments, each one exactly one unit long.

A car can park on any two adjacent free segments (i.e., it does not need any extra maneuvering space).

The problem

Back in 1996 I was working for the Symbolic Computation Group at the University of Waterloo, developing algorithms and code...

I would like to pay  attention  to the PhD thesis by John Baber in an actual field of complex analysis done with Maple: http://arxiv.org/PS_cache/arxiv/pdf/1106/1106.4737v1.pdf . It should be noticed that the usage of Maple is an essential tool of this work (for example, see p. 28, 43, and around), not a fashion trend.

Just wanted to let everyone know that there is a Maple 15 update available. Maple 15.01 provides:

• Enhancements to MapleCloud security settings
• Improvements to tools supporting multi-process programming on a local grid
• Extended MATLAB® connectivity to include MATLAB® R2011a
• Compatibility with MapleSim 5

To get this update, you can use Tools>Check for Updates from within Maple, or visit for ...
