@MrWizard I'm not sure. If it stimulates answers discussing if, and if so under what conditions, one can legitimately consider results obtained using Mathematica "proofs", it could be interesting. On the other hand as stated currently it is not hugely constructive.
@MrWizard I certainly don't think it's that bad of a question that it needs to be closed straight away. Personally, I would take a quite laissez-faire attitude to moderation of questions: if they get closed by the community, fine; if they get answers, even better. The question is not too constructive but it is not destructive either.
It wasn't my intention to close the quesiton to "punish" the asker; rather it is a matter of which site it belongs on, and in that case I think a close and/or migration is better done soon. Also, you'll notice that I am polling the chat room for opinions before any action.
@MrWizard well, Math.SE is not always super receptive to Mathematica-based questions, so I think the asker will benefit from it being here for at least a little while, and if nobody picks it up, then it can be migrated by all means. Also please don't take my comments as criticism: I have been a moderator too, and it is a difficult, thankless task that I would not readily do again. I just think you shouldn't make it more difficult for yourself than necessary by being too proactive. :)
@Rojo Ok, but then does it really differ if I do Plot[..., PlotRange->Dynamic@range] instead of Dynamic[Plot[..., PlotRange->range],TrackedSymbols:>{range}] ? In both cases the full Plot[...] HAS to be updated when range is changed, so it does not matter, does it?
I mean, for any other case, it would be an alleviation to use a local Dynamic (e.g. when updating a Point or such), but for PlotRange, the plot has to be redrawn.
@Rojo Hmm, yes, you mus tbe right. Best is to test it though.
@Rojo Ok, I restructured it and it IS faster this way! Buuuuuut....
So now all Plot/Graphics object are static inside the Show, and only the PlotRange option of Show is Dynamic. Updating is faster, but then it only updates if the mouse is moved. Otherwise the yellow arrow will just go past the edge of the panel. Some more expereimentation is required. Back to the drawing board.
Anyway, let's just call it a night, thanks for all the help, and see you tomorrow/Monday!
@R.M @verbeia @mr.wizard The tiff question has had an update that I hadn't noticed. Graphics file corruption apparently was the cause of all this. I now agree with the close reason and will delete it, as there's nothing to be learned from the question as it is now.
@SjoerdCdeVries I'm glad to hear that. I work all the time with 32-bit FITS files, and when you import them the values are changed to reals. It's not a problem for my application as it happens, but it is slightly questionable behaviour, which had led me to doubt the correctness some of the import converters.
I think probably the blocks will have to be smaller than the Tetris ones in most cases (or the game board taller) because you will get a lot of cases where rows can't be made to disappear easily.
So 1×1 sounds fine to me.
It does mean that you won't be able to have the blocks become invisible in the highest levels like they do in Tetris though. :)
@SjoerdCdeVries yes, I appreciate that. But 32-bit TIFFs aren't common, just like 32-bit FITS, so I had wondered if the problem might have been down to inadequate testing of this possibility. Glad to hear that it wasn't.

System dynamics is an approach to understanding the behaviour of complex systems over time. It deals with internal feedback loops and time delays that affect the behaviour of the entire system. What makes using system dynamics different from other approaches to studying complex systems is the us...
@markmcclure The question was deleted by an additional three members so I cannot respond to your comment there. Let me first state that I don't revel in closing questions. I've clearly stated on numerous occasions that I don't like closing questions too much as it may influence the friendly atmosphere we generally encounter here. I have contested the closing of questions here in chat as well in comments on quite a few occasions, as any regular here may attest.
Having said that, closing is sometimes necessary. The question we are discussing now involved just a dump of code and a request to explain that. The current community opinion that I distill from previous discussions in chat and meta is that those questions should be closed. The scope is overly broad, there is no clear question and there is no overarching theme involved here that could make it useful for someone googling for a Mathematica answer.
The community has also made clear that askers should show effort. That too was not the case here. The OP has already posted 5 questions and is therefore not a beginner anymore and should know better.
You said that you consider taking this to Meta. I'd encourage you to do so. I think I can speak for my co-mods here: we ask for opinions and we do listen. This is not a one-man show (or a three men show for that matter), this is a community thing.
@SjoerdCdeVries I agree entirely that the asker hasn't shown much effort. Neither did some of his previous ones. But the FAQ does say "if your motivation is “I would like others to explain ______ to me”, then you are probably OK". So I think the question itself is on-topic by the letter of the FAQ. I think it would be possible to put together a nice answer that went through the code and explained it. (I don't have time to do that today, though.)
I don't know if it is possible to make it clearer in the FAQ that we expect people to make some effort in their questions.
@RM what about systems-modeling? (with obligatory double-L synonym)
@SjoerdCdeVries actually, he's posted 9 questions? High school student - not sure how much effort we will get out of teenage boys :)
