However the larger the window size more of the information is lost at the ends of the list.  It's not really a reduction in data points the way I thought.  

Whoops right, thanks.  My mistake I forgot about the window size value.

I still have the same number of data points.  How can I reduce that number with minimal loss of basic shape information.

Thanks alex_01 but the BSpline method looks easier. 

The MovingAverage method doesn't work on a list of [x,y] data points.  You first have to seperate them and then average them and then recombine (there must be a simpler command for that).  This is what I came up with before I saw the BSpine way (thanks Alec).  Here's what I came up with using the MovingAverage method.

with(plots):
with(Statistics):
a := [[1, 1], [3, 2], [3.5, 4], [4, 6], [5, 5], [6, 7], [7, 6], [8, 5], [9, 5.5], [10, 4], [11, 1], [12, -5], [11.5, -6], [12, -12], [10, -10], [8, -14], [7, -10], [3, -10], [2, -5], [1, -8], [0, 0], [1, 1]]:
b:=[seq(op(1,(op(i,a)),i=1..nops(a))]:
c:=[seq(op(2,(op(i,a)),i=1..nops(a))]:
bb:=MovingAverage(b,2):
cc:=MovingAverage(c,2):
dd:=[seq([bb[i],cc[i]],i=1.nops(bb))]:
listplot(dd)
or plot(dd) will work too

I'm sorry I have to write this post but I was just over there.  I'm here on the old mapleprimes because there is no typing delay

The number one issue is typing in a comment.  Extremely slow.  I am on dial up, high speed users may not experience this but I type maybe 6 words in a row then have to wait 20 to 30 seconds for my sentence to appear.  That is pain. 

I have a regular monitor (not widescreen) and there is a lot of unused blank space at the sides (maybe they'll add to it later) but right now it's pretty wastefull.

You can only view 4 questions at most - this is also painful.  The content (question and summary) is not highlighted enough.  I'm really sorry about the use of the site but to me it is confusing.  Very pretty though, however doesn't mean anything if you can't use it well.

I couldn't find a question summary page, and those giant user headings WOW lots of real-estate space wasted on highlighting who is posting the question. 

The thumbs down is a neat idea but I think is a bad one.  Although I should hope not but someone may decide that he/she does not like someone because of what he/she posted at some earlier time and just thumbs down on him/her when he can.  Now suppose this is an important post with some good information inside, would it not get shuffled to the end of the line?  On the new mapleprimes site I believe it would be impossible to find such a post where on the old mapleprimes it would be viewable in order last answer added to the post. 

FONT SIZES - oooweeee - can we multiply that size by 0.25 or something? 

a:=convert(NewMapleprimesSite,Array);
b:=0.25*a

In my opinion some work needs to be done on the new mapleprimes.  It's not very user friendly to me anyway.  Do other people testing the site like it as it is now? 

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.
