ooo, I almost forgot this one. 

Maple Challenges

- users could post simple or hard challenges to other maple users.

Okay it seems I've found some bugs and problems in the new mapleprimes already.

I asked to sign in to review the site.  And I meant to login a few weeks ago however I ran into some problems so I thought I would just sign in later.

I've just got around to signing in now and it appeared at first someone else had taken my user name so obviously out of frustration I changed my username to Christopher22 and my account was migrated to the new user name.  However I found my original username was under an earlier signed email account and so of course I signed in using my original username and migrated from there. 

Now my rating is Christopher2222(0) so does this mean all of my original postings have gone to the other account I set up??  which has a user rating of Christopher22(48) ??? 

I'm a smidgen confused and perhaps someone can clear that up.  The other problem I experienced (which is why I'm posting here) is the area to insert the body of a question for a post was completely hidden from my view.  Perhaps it is because it is in the process of going public next week, I don't know. 

A couple of other points I might bring up.  It is quite difficult to quickly see the questions a poster is asking and the fonts are HUGE I mean big.  So big that you can only view a few questions before you have to scroll the screen.  And the ratings points, now that's cool but they are also overwhelmingly large and really aren't that important in which case should be smaller. 

Sorry to vent here but I couldn't post on the new mapleprimes site.  The new site is aesthetically pleasing, yes that's for one thing.  But in just my short minutes visit to the site (maybe it's supposed to grow on you) but it didn't quite grab me as I had expected. 

Font sizes and the ratings for each user were large graphics and in your face, not as I would like to see considered an important feature (after all you want your most important features to stand out the most - and that being the questions being asked). 

Can we still track our own posts? 

Sometimes I've posted a question and need to re-look it up and I know I've posted a question for it.  A simple search of my posts reveals it.  Otherwise I have to scour tons of posts if I can't remember a good search string to find it. 

Is there a list of bugs that were fixed from previous versions? 

As well as improved areas or newly added ones a bug fix list is also a very important and huge factor in determining whether someone wants to upgrade or not. 

Who deleted them?  I agree that some long time users would have the ability to delete posts but I think the level of power was too high.  They should only be able to delete posts from posters who have just joined (a lot of the time, some of these are spam).  Posters who have posted at least more than 50 posts or so are a little more respectful in the community. 

So the question remains ... Who did it?  Was it by accident?  Was it a migration issue to the new mapleprimes site?  Was it hackers? 

In any case it would be very unfortunate to the mapleprimes community to loose alec's input. 

I suppose I could just use the replace text in wordpad to rid me of the W.  However still I wonder how it can be done with Maple.

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.
