  • Here's an assume vs assuming difference worth keeping in mind

    In the recent tab, the time goes from 59 min to 2 hours ago. There is no such thing as an hour ago.

    Before I used to be able to call a list of everything I ever posted into one list ... nice

    Now I have 3 seperate buttons I have to search (all questions, all answers or all posts) to go to if I'm searching for something I posted.  It is slower than before so even though it's only 3 buttons to search through, it's a bit of a pain.

    Can we have one button for that?

    When typing in mapleprimes there is a delay when you type.  I am on dial-up so if you highspeed users think it's slow, it is.  Fixing this problem will help speed up high speed users too.

    William fixed this issue a while ago but this problem has come back about a week ago or more.

    How is the mapleprimes site usage statistics now after the site change over?

    Does the site have less traffic from it's regular or veteran users?  I know there are many more posts related to mapleprimes format and probably less related to Maple software except for new users popping in to ask questions. 

    I find myself visiting this site less frequently than I used to. 

    I am using Maple 14 in Windows xp.

    If you enter an equation, or expression into a table the screen display shows more than adequate amount of blank space remaining in that particular table row.  However, when you look at the document in print preview or after printing it out you find that the free space in the row is not correctly displayed.  This is by no means subtle.  For example, I enter an equation into a table and it looks like at...

    I've seen a few people talk about how they are bookmarking /recent/all instead of /recent/unread. I wasn't sure why they were working this way, but realized they might not realize how /unread works.

    /unread lists all Posts and Questions on MaplePrimes that you have not viewed. Once you click on one of those items, it no longer appears on the list. However, if the item is updated or a comment or answer is added to the item, it will re-appear in the /unread list. This means that by checking /unread, you will see everything that is posted to MaplePrimes, even if it posted after you last viewed that thread.

    I believe the confusion was that items don't re-appear in the /unread when replies are posted, so people were viewing /all so they could see everything. I hope this clears things up.

    I just fixed several of the MaplePrimes badges. Two of the badges, 2-Dimensional and Historian weren't being awarded when they should have been. This has been fixed, and now two people have earned the 2-Dimensional badge, and 91 people, the Historian badge.

    I also updated the text for the "Popular Post" and "Popular Question" badges. They both now state that the question needs to be viewed by over 1000 people. The number that is displayed at the bottom of Posts and Questions is the total number of views, so refreshing the page counts as another view. To earn the badge, 1000 unique IP addresses need to view your Post or Question. There are several items that have almost 500 unique visitors thus far, so in a couple of weeks, the first people will start earning these badges.

    Scrolling through the search results on tags - like "bug" or "mapleprimes" gives an error "file not found", if trying to go beyond page 1

    The old subsciptions are trashed, unfortunately.

    But how about new ones? It seems I only can subscribe to my own replies, but not to a thread I want to follow or look at it later (for example when this board allows to save threads locally in a convenient way).

    Do I miss the solution or is it true?

    Does the Historian badge verification work only for Questions posted since the Mapleprimes system upgrade?

    Saving a 3D object computed in Maple.  Maple itself has only limited capabilities for this.

    There is a Maple library called JavaViewLib that sends the data from Maple to a Java applet called JavaView.

    From there it can be viewed and saved in many different formats.

    Find all the info at www.javaview.de

    The last web page update was 2006, but the server that provides the free licenses is still running.

    Mostly JavaViewLib...

    I have noticed that editing in Maple 14 in document mode becomes very sluggish if the Greek palette is left expanded while editing.  I also seem to see a refresh of the palette (maybe a very quick flash) at this time also.

    Editing seems to return to normal if the palette is closed.

    I am just curious if anyone else has observed this behavour.

    Some Posts and Questions contain broken links to files uploaded in the "old Mapleprimes". We've heard that some files (eg. image files) may be irretrievably gone.

    But here is a curious page. It had an associated .mw worksheet uploaded. And the link to the uploaded .mw is now broken/stale, at the moment that I write this. But the link to view it with the maplenet viewer, in one's browser, still works. Not only that, but the .mw worksheet can be saved from within that viewer (via a URL distinct from the broken link on the Post).
