Now I'm at a computer with maple, I thought that frontend would cleanly take care of the x^2 as well, however when I calculate it I get an error.

y:=sin(x)*x^2;

frontend(diff,[y,x^2]);

Error, invalid input: diff recieve x^2, which is not valid for its 2nd argument

I was expecting to get sin(x) as the answer.                     

Okay I did some further testing.

It seems to be an issue for Maple 12.0 only, it doesn't happen in Maple 12.01 and it works fine Maple 11 and Maple 13.

I thought I had come across a bug but I'm glad to see it has been fixed in newer versions. 

I've experienced exactly what Doug has on occassion.  The last time I uploaded a picture was a few weeks ago though, but when I did it uploaded a previous picture was opened.  So all I did was change the name and try uploading again and it worked.  It happened again the very next day. 

I haven't uploaded another picture since then so I'm not sure if that problem still exists for me. 

Hashing must be more efficient.

On a related note why when print(a) displays a table but when I use whattype(a)  Maple says it's a symbol?

Nice choice. 

I'm a Toshiba man myself so I am very biased.  I have an old satellite 5100ct, 8100 tecra and a portege.  No complaints from any of them except for the tecra 8100 (screen spring broke and had to resolder the power cable connector inside (known bad design) and also needed to resolder the memory memory pins to revitalize the failing memory B slot, tricky but successful).

I would choose a Sony over a Dell.  My first choice is a Toshiba although it's really a matter of taste, you can't go too wrong with any of them.  Sony, Toshiba, or Dell, they're all pretty good. 

Just wondering if you are going to have the old Mapleprimes (but locked so no one can edit new quesitons there) and the new Mapleprimes website run in tandem for a couple of months when the new one is released?  But only for comparison purposes.  Sometimes it takes a while for someone to recognize something important is missing and could prove to be valueable.

Funnily enough, there are still operations that work in the classic version but not in the "newer interface", I wouldn't get rid of it until those are cleared up.  It's also less resource intensive.  Makes those old low powered computers still useful in some way.

Just recently brought up left quotes will not work in the newer interface with a backslash escape.  eg `name\`s` only works in the classic version.

However with some ingenuity one would simply use the other single quote and not have to worry about the backslash ie. `name's`

Unfortunately in the help pages the left quote is specifically used and I quote from the Names help page

Two successive left single quotes that appear after the opening of a name are parsed as a single left single quote. Thus, `abc``de` yields abc`de. Alternatively, a left single quote can be written within a name by preceding it with a backslash (\), for example, `abc\`de`.

In this case though, they are referring to the classic version of maple and have not updated the help page to reflect new changes that have occurred in Maple over the years.

Indeed, there is a wealth of information in the book pages that many newcomers do not use and many times even some year and two year old newcomers haven't had chance to explore yet. 

Great Maple links, Great Maple Tools and Resources, Tools of the Maple Masters and the Maple FAQ to name a few of the gems that may have been forgotten. 

Maybe on the new site have a link/door/portal hey that sounds cool, a portal door, a portal to Maple knowledge?  I don't know but it sounds good, yes?  maybe ?  Just a thought, ... I'd hate to have mapleprimes loose information.  New and improved but not lost.

Looking good.  As long as message content is not lost it looks like it'll be good. 

I like the track message feature, I hope that is not lost.  And the book pages along with tools of the maple masters, they often times give some good, if not great, insights.

You might want to try out your last statement.

If I give writedata the name as test then the filename "test.txt"   is  produced. 

 If i delete or move the folder named data from the Maple directory the data name will work and be written as "data.txt"
