I noticed Mapleprime have entries of users who clearly create an account just to put a bad website URL in there and they are just spam.

Why do not the moderators of Mapleprime purge these out? Mapleprime is full of these spam marketing users.   Here are just few I found in few clicks

There are hundereds of these spam URLS in there. They make an account, only to add their infected web site URL there so if someone clicks on it they get virus.

Moderators of mapleprime should do better job and remove these cleary spam entries from Mapleprime.

I do not think the current API for dsolve when asking for series solution is done right. If one wants to obtain a series solution for an ODE, but wants different order than the default 6, now one must set this value using a global setting before making the call, like this:

eq:=diff(y(x),x$2)+y(x)=0;
Order:=10;
dsolve({eq,y(0)=1,D(y)(0)=0},y(x),type='series');

It would be better if options to calls are passed along with the other parameters in the call itself. Something like

dsolve({eq,y(0)=1,D(y)(0)=0},y(x),type='series',order=10);

This should also apply to any command that takes Order, such as series(cos(x),x=0,order=10);

Passing options and values to functions using global and environment variables is not safe and not a good way to go about it as it can cause programming errors.

Maple 18, document mode. Please try this:

>restart;
>some_long_name:=3:
>f(som)

Now, as the cursor is right after the "m" above, hiting the ESC key to autocomplete, nothing happens. Only a beep, meaning Maple does not know about the variable name I wanted to expand to, which is "some_long_name". What I do now is manually add a space by  pushing the ")" away, like this:

  f(som )

And now put the mouse back in front of the "m" and now hit ESC. Maple now can see the name I wanted.

Really? This is very bad design. You might ask, why did I close the () first? Well, I like to start by writing () then fill it in, or it can be that I am changing things, and wanted to write a new name, and the () was allready there. I use name autocomplete alot, and it is very annoying to not be able to use it if happens that there is a ")" or "]" right next to the name.

Having to keep pushing the ")" away, so that Maple can see the name makes no sense since ")" can't part of a name.

In Mathematica it just works. I can do

someLongName = 3;

Then in a new cell,

f[som] and hit CTRL-K  when mouse at the letter "m" just typed it in, and it will autocomplete.  I did not have to push "]" away first.

Please Maple, fix your user interface so it is less awkward and annoying to use. This is version 18 of the software, and not version 1.

 

I find this very strange. I see questions posted at Maple prime using a language other than English.

I do not know if this is a Mapleprime bug, or not. If this is not a bug, why is it allowed to post questions in a language other than English?
 

I am baffled by this choice of Maple. When one goes to Maple website and look at the help pages on the web, like this

http://www.maplesoft.com/support/help/Maple/view.aspx?path=convert/rational

Then all the commands in the help pages are shown using build-in images. This means if one sees a command they want to copy to try, they are not able to copy it using the mouse since it is an image, or even may be to copy it to some text file for later use, email it, etc...

Basically one can just look at it. 

Compare this to Mathematica web help page

http://reference.wolfram.com/mathematica/ref/Rationalize.html

Where one can click on any Mathematica command, and a small windows opens with plain text format of the command that one can copy and paste anywhere.

Not only that, the formatting of the commands in Maple help pages are all in the new document mode style (the italic math font used, which I can't stand looking at, that is why I do not use document mode). 

So, for someone using worksheet, and want to see the good old fashioned Maple commands (1D, nothing fancy, plain text), they can't find those.  It would be nice to have a version of the help web pages in 1D, for those who want to browse help in classical Maple code and not interested in all document mode.

(Yes, I know I can do that in Maple itself on my desktop, but many times I use google to find a Maple command, and it leads me to Maple help pages, and then I find I can't copy the command). Then I have to open the local help page on my Maple, and look for the same command again in order to copy something).
