I just wanted to show how Mark Walked locked and somehow sorted the list so that a thread with activity three days ago would show up between one from 7 months and one from 5 months ago.

The display order is affected by each user's preferences. In the normal indented thread order, you will find your new post [almost] immediately after the thread you replied to, unless it had other sub-replies, and immediately following your reply will be a different reply to some part of the thread higher up the hierarchy. Thus it will have two 'old' threads either side of it.
Sometimes it is just what is wanted, and other times it means that all the latest news is scattered about the whole thread. On the old forum I used the simple date order and managed my reading using the "mark as read" but that isn't available any more so I've resigned my self to just reading the last few threads that look interesting and ignoring the rest. Have a check as to what your preferences are set to. You may want to change them.
I don't like the competitions anyway because they always need 'hidden' rules [= things obviously misunderstood (that's an oxymoron;-)] that I don't always 'get'.
No, I'm not talking about the order of the posts in thead but the order of the threads in the "puzzles & games" section. He did this so that it would not show up on the "What is everyone doing?" list on http://communities.ptc.com/community/mathcad?view=overview. See attached.
The moderator closed the thread because it is about a puzzle we posted more than 6 months ago. The purpose of that puzzle was to showcase the Mathcad Virtual Event last fall, and encourage people to pick up clues at the various stages of the event.
We'll be having another Mathcad Virtual Event later this spring, when we'll discuss where we are with Mathcad Prime 2.0 and our ongoing roadmap. Stay tuned.
Exactly, six months without providing an answer to my question about hidden rules. He then changed some property in the thread to hide this.
Is it policy to lock old threads? I understand the purpose of the puzzle and I attended the event. I provided the first correct solution to the problem.
I'm not aware of any hidden rules, nor do I know how the winner was chosen. It may have been randomly among correct answers, like many contests.
The moderator of the communities decides when to lock threads.
From the other thread:
I didn’t know this debate was still alive, so hopefully I will settle the discussion, at least for a few minutes….
Jean Giraud’s answer did not involve any of the specific pieces of information that were disclosed through the presentations.
Beyond that, Tom MacMillan’s trajectory curve omitted the initial (launch) height of the cannonball. So, his trajectory curve was 75m below where it should have been
We clearly stated that the launch height was 75m above the crater floor…. Not that the crater floor was 75m below the launch height.
Therefore, Chris Kaswer’s answer, although received 10 minutes later, was correct because he included the +75m term in his vertical displacement calculation to drive the trajectory curve.
This is not true. They had a diagram showing a two arrowed dimension "H" . During the event they gave the length of "H", no direction. There was no random selection. They gave this as the only reason that the other (later) solution was better. I used the vaue of "H" to provide what was aked for. See the other (locked) thread for other issues. I wonder how long it will take for this thread to be locked or deleted as well?
Ultimately the winner is selected by the judges panel and the decision is final. Mark and others were fair in their response to your question to why your solution was not chosen.
There are plenty more chances to participate in challenges. Plenty more chances to win gift cards and other prizes. You are more than welcome to join us for those future opportunities, but this challenge is closed.
