Things aren't looking good, measurement quality is terrible and unreliable.</p>
<p>I was wondering if there is any other method of finding out whether the player (its for a game, or some interactive experience platform) has moved his location a significant amount (> 1m).</p>
<p>I don't need accurate readings (although that would be great), just knowing whether the player is moving or standing still would be a great help. I wouldn't even know where to begin to look for this, and I haven't been able to come up with any brilliant ideas myself.</p>

4,045,365 | 4,045,366 | how does C# search for best match overloaded method | <p>I got several questions about calling overloaded(or maybe I should call them hidden) methods in C#. Suppose I have classes as following:</p>

public void DoJob (ParaA a){Console.WriteLine ("DoJob in TheBaseClass is being invoked");}

//Case 4: which version of DoJob() is being called?

<p>I hope that I have made myself clear about what I am trying to do. I want to know how will C# search for the 'matched' version of method to invoke, when the parameters provided by the invoker do not perfectly match any signature but are compatible with some signatures. It makes me even more confused when methods are not just overloaded within a class, but also hidden, or overrided, or overloaded by derived classes. The example above does not cover every possible scenario. Is there any term for this?</p>

4,828,575 | 4,828,576 | Issue with a php form | <p>I've created a very basic php form for a website and the form mostly works - only problem is that when the form is emailed to the gmail account, only one line (the "college" line) shows up in the email, with the rest blank. The sender's name ($field_name) appears in the subject line of the message (along with the xxx.Org TShirt Order part of the message), but the only line that appears in the body of the message is the "college part".</p>
<p>Here's the code (I'm aware that it's not sterilized... I'm really new to php and I don't feel like I've got a handle on the language yet, so I'm starting really basic):

<p>reads ...</p>
<p>Don't compare boolean values to True or False using ==.</p>
<p>Why?</p>
<p>Edit
Just to make it clear what im asking (and it's indicative of the problem itself), when you write </p>
<pre><code>if something:
print "something is true"
</code></pre>
<p>You are doing an implicit conversion to a boolean which may or may not work depending on what true means. IMHO this form of programming is discouraged because of the side effects it can cause.</p>
<pre><code>numberOfApples = -1
if numberOfApples:
print "you have apples" # is not what is intended.
if numberOfApples == True:
print "you have apples" # is also not what is intended.
iHaveApples = numberOfApples > 0
if iHaveApples is True: # Edit: corrected this.. the "is" is better than the ==
print "you have apples" # is correct.
</code></pre>
<p>Implicit conversions disguise logical errors. So why does the style guide encourage this? </p>

I use the following code: </p>
<pre><code>$(".portlet-topper").click(function(e){
e.preventDefault();
$(this).siblings(".portlet-content").toggle();
});
</code></pre>
<p>To clarify before a click:</p>
<p>|----portlet-topper-A----|</p>
<p>|----portlet-topper-B----|</p>
<p>After A is clicked:</p>
<p>|----portlet-topper-A----|</p>
<p>Portlet Content of A</p>
<p>|----portlet-topper-B----|</p>
<p>If I click B, the content of B displays, and A's is left displayed as well. If A has been clicked, I would like the clicking of B to display B while hiding A. How would I go about coding in this logic? I would need this to work for any number of divs, not just two. Essentially, allow only one set of portlet-content to be displayed at once. I figure I'd make explicit calls to show and hide, rather than toggle. Even still, I'm not really sure where to start...</p>

3,273,996 | 3,273,997 | How to optimize the updating of values in an ArrayList<Integer> | <p>I want to store all values of a certain variable in a dataset and the frequency for each of these values. To do so, I use an <code>ArrayList<String></code> to store the values and an <code>ArrayList<Integer></code> to store the frequencies (since I can't use <code>int</code>). The number of different values is unknown, that's why I use <code>ArrayList</code> and not <code>Array</code>.</p>
<p>Example (simplified) dataset:</p>
<pre><code>a,b,c,d,b,d,a,c,b
</code></pre>
<p>The <code>ArrayList<String></code> with values looks like: <code>{a,b,c,d}</code> and the <code>ArrayList<Integer></code> with frequencies looks like: <code>{2,3,2,2}</code>.</p>
<p>To fill these <code>ArrayLists</code> I iterate over each record in the dataset, using the following code.</p>
<pre><code>public void addObservation(String obs){
if(values.size() == 0){// first value
values.add(obs);
frequencies.add(new Integer(1));
return;//added
}else{
for(int i = 0; i<values.size();i++){
if(values.get(i).equals(obs)){
frequencies.set(i, new Integer((int)frequencies.get(i)+1));
return;//added
}
}
// only gets here if value of obs is not found
values.add(obs);
frequencies.add(new Integer(1));
}
}
</code></pre>
<p>However, since the datasets I will use this for can be very big, I want to optimize my code, and using <code>frequencies.set(i, new Integer((int)frequencies.get(i)+1));</code> does not seem very efficient.</p>
<p>That brings me to my question; how can I optimize the updating of the <code>Integer</code> values in the <code>ArrayList</code>?</p>

<pre><code>public abstract struct Id
{
int _value;
public Id(int value)
{
_value = value;
}
// define implicit Id to int conversion operator:
public static implicit operator int(Id id)
{
return _value;
}
// define explicit int to Id conversion operator:
public static explicit operator Id(int value)
{
return new Id(value);
}
public bool Equals(object obj)
{
if(GetType() == obj.GetType())
{
Id other = (Id)obj;
return other._value == _value;
}
return false;
}
public int GetHashCode()
{
return _value.GetHashCode();
}
}
struct PersonId : Id { public PersonId(int value) : base(value) {} }
struct ProductId : Id { public ProductId(int value) : base(value) {} }
