In the notebook below, how can I:
Make the plot as large as the light blue area
Set initial values for the sliders
Make the MousePosition appear at the tip of the arrow instead of at the bottom of the panel
For the last slider (the time) slider, I would like to use two sliders instead one to se...
I am new to this forum - I wonder if someone can help me improve this code.
I would like the angle $\theta$ to start in the middle of the slider i.e. $\theta = 0$ instead of starting at $\theta = -90$.
How do I keep the circle size constant as I slide the $\theta$?

@Heike but I don't think you downloaded some incomprehensible Google Code, went to an Objective C forum, and asked how to tweak the code so that it did what you wanted
My point is
I don't think that by answering those questions the OP is learning much
The ones with big bunch of codes that ask you something very particular of that problem... Even if a good honest question could be interpreted from that, it's not what they are asking.. . I'd say "too localized"?
In fact, he asks 4 things in the same question so it's unsearchable
Oh, I completely agree with that. It looks like they just copied the code from somewhere and now just want us to tweak it so that they can turn it in as an assignment
It's a bad copy paste... people usually fall in two categories — they use a space for Times or they use *. Usually they don't mix the two unless it's copy-pasted + edited + tweaked
Why do people want to work without Manipulate? For example, questions like this. I can't see how that would be a useful homework question. It doesn't seem like they're building something either...
I don't know if some people (newer users) don't vote to close because they think a moderator will do it, but it always looks better if 5 users from the community do it
@Rojo I agree and I think they're lying too, but bullying is not going to help. This is the same as the homework crowd on SO who just beat everyone that asks a noob question with a hammer
@Heike No, I hope not. It's just not normal for her to go out of her home, let alone in cold weather, and she isn't there since the morning. I just went there
(At least since this morning)
Fortunately, it all looks like she left on purpose, leaving everything neat
@belisarius For example in this question I tried to format the code block by putting 4 space in front of it like usual, but that didn't work which was caused by the enumerated list directly above it. Putting in a <pre><code> block worked, but I was wondering if there is a way using the normal shortcuts.

there was once a question in here about DynamicWrapper
and what it's for
The answers more or less were "yeah, basically, it's almost useless when you have Dynamic"
but I find it terribly good to organize the dynamic code and make it efficient
You can separate what you show, putting Dynamic[variable] in the small parts where you need dynamic things, and then in another part just decide what updates what
And if you do Fold[DynamicWrapper, interface, Unevaluated{update1, update2, ...}]
update1, update2, etc, are all done independently of each other
Leonid predicted that, as the site became better known, we would get more newbie questions. Questions like this one. I don't think we have yet seen an avalanche of such questions, but inevitably we'll get a few each day.
In responding to these questions, I hope we never lose sight of what made u...
Anyway, too bad, I wanted to have some shortcuts in my browser so that when I click on them the code sections could be rendered the way they do in here.

The first question in there is the same he had asked in another question, and I think was cross posted in SO. And they were all part of the same bunch of questions. I don't see how they are productive
The comments in those questions are not bad. I've gotten sort of... I don't know how to put it, but scolded? when I ask some questions in stackoverflow (particularly from the C++ guys)
