<p>In a PHP 5.3 script I am including another PHP script using the following code; </p>

<p>In php.ini the include path is: </p>

<p>If I execute moninit.php directly using a browser, it works fine. So, somehow the include cant seem to find moninit. SensorW is also in the same folder as moninit. </p>

<pre><code>>>> class Foo(object):

<p>Now I can see that exists on <code>Foo.bar</code></p>

<p>And I can retrieve it.</p>
<pre><code>>>> Foo.bar.xyzzy

<p>Approach1: Create a static ListA in one of those activities and do all my stuff of that static ListA.</p>
<p>Approach2: Create a static list in another class which I use just for storing this List and doing all my stuff on this list. But this means that this stays as long as my process is running and I have to manually set it to null when I do not need it.</p>
<p>Approach3. I am extending the above class to implement it using a static HashMap.
I have two methods one to store the list in a static HashMap using a unique key and another method to retrieve the list and remove it each time data is retrieved so that the List is no longer present in the static HashMap. So we essentially have to pass only the random key generated to store data between activities which I can pass as an extra using Intents.</p>

<p>What I've created works fine. The problem that I'm having is that out of 100 hundred users submissions 2 out of the 100 submissions return the wrong results. The closest location didn’t correspond to what was returned.</p>

<p>I’ve even looked up the postal code that the users entered on Google maps and the location was good, as well as my XML list of locations which the API will return the closest driving distance to that location with a comparison made from my XML.</p>

<h2>Use <code>Application</code></h2>
<p>I first thought, there will be only an <code>Application</code>, shared among 2 different processes, as their are origin from a single application. </p>
<p>But that is not the case. I realize, before a main <code>Activity</code> is created, an <code>Application</code> will be created. When I spawn a remote service, another new <code>Application</code> instance will be created too.</p>
<h2>Use <code>Preferences</code></h2>
<p>My first thought is that, this is a file based. So, whenever I write a value to <code>Preferences</code> through <code>sharedPreferences.edit().putString(key, value).commit()</code>, the change will be committed to file. Another process should be able to read the latest changes. </p>
<p>But this is not the case. My guess is that, this is because in my service, I acquire the <code>Preferences</code> instance only once during service start up through <code>PreferenceManager.getDefaultSharedPreferences(application)</code>. It only read value from file during 1st time. Subsequent call <code>getString</code> will be read from memory.</p>
<h2>Use Global Static Variables</h2>
<p>Not workable as <code>Activity</code> and remote <code>Service</code> are in 2 different processes. They are having 2 different memory spaces.</p>

I keep looking at this code, trying to trace it, but I just cannot figure out:</p>
<ol>
<li>What it's actually meant to do</li>
<li>How it works</li>
</ol>
<p>As far as I can see, the very first time it's called it's the only time <code>action</code> is the same as <code>callFn</code>. So, the very first time it's run, it creates the stack array. Then I lose it. Action is assigned a function that just adds the passed callback to the stack. Then fn is <em>actually</em> called and based on its result, "action" is set to either callFn (?!?) or to a function that calls the callback... And then, all the calls in the stack are called.</p>
<p>I hate getting lost in code, but this is a little beyond me. Anybody smarter than me able to "get it"?</p>
<pre><code>var memoize = function(fn) {
var callFn = function(callback) {
var stack = [callback];
action = function(callback) {
stack.push(callback);
};
fn(function(err, val) {
action = err ? callFn : function(callback) {
callback(null, val);
};
while (stack.length) stack.shift()(err, val);
});
};
var action = callFn;
return function(callback) {
action(callback);

<p>This results in the soft keyboard popping up with the '@' and '.' (and some keyboards '.com') keys on the initial keyboard layout. Great just what I want.</p>

2,043,556 | 2,043,557 | lift list of values to a list of lists of values | <p>Here's a tricky one. I want to take a list of integers, and turn it into a list of lists containing that integer. This is so that I can later append to that list. Unfortunately <code>list()</code> does not take a single integer, so I can't <code>map</code> it to the list.</p>
<p>Here's a more concrete explanation:</p>
<p>Given,</p>
<pre><code>>>> a = range(5)
>>> a
[0, 1, 2, 3, 4]
</code></pre>
<p>How can I elegantly turn it into,</p>
<pre><code>[[0], [1], [2], [3], [4]]
</code></pre>
<p>I tried <code>map</code>'ing <code>list</code>:</p>
<pre><code>>>> map(list,a)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
TypeError: 'int' object is not iterable
</code></pre>
<p>Same thing with <code>tuple</code>. In fact ideally I'd be able to map the tuple or list operators, but of course that doesn't work with Python's syntax:</p>
<pre><code>>>> map((,),a)
File "<stdin>", line 1
map((,),a)
^
SyntaxError: invalid syntax
</code></pre>
<p>So the only way I can come up with a solution is to define my own list constructor:</p>
<pre><code>>>> L = lambda x: [x]
>>> map(L,a)
[[0], [1], [2], [3], [4]]
</code></pre>
<p>That works fine, but I'm wondering if there is a more Pythonic solution. Mostly I was just surprised to discover that <code>list(3)</code> does not give <code>[3]</code>.</p>

4,574,894 | 4,574,895 | pg:224 Stroustrup - C++ Programming Language, 3E | <pre><code>struct Date {
int d, m , y;
void init_date(Date& d, int, int, int);
void add_year(int n);
void add_month(Date& d, int n);
void add_day(Date& d, int n);

Date tomorrow = today;
tomorrow.add_day(1);
// ...
}
</code></pre>
<p><strong>Question A:</strong> In the above snippet, isn't:
Date tomorrow = today;
wrong in the sense that there is no "copy constructor" provided within
<em>struct Date</em>. I know there is a "default constructor" auto generated by
the compiler - but I'm not sure what exactly it does or how exactly it
works (it can call the default constructor of a member-class, but it
doesn't initialize: int i; and stuff like that). Could someone clarify
how the compiler's default constructor works?</p>
<p><strong>Question B:</strong> We would have to insert something like this:
const Date& Date(const Date& r);
correct? But, the above constructor implies we pass it one argument (a
reference to "today"). So, how does an "initialization": <em>"Date tomorrow =
today"</em> translate to a function call: <em>Date tomorrow(today);</em> Is there any
"magic" happening here??</p>
<p><strong>Question C:</strong> What is the format of the operator, new? Stroustrup uses it
in different ways but there's no clear listing of all its uses. So far I
could find:
new ;
new Type[size];
new Type(size);
new Type;
Is this listed/given anywhere? Have I missed out any?</p>

<p>• When the user clicks the “Save” button, write the selected record to the file specified in txtFilePath (absolute path not relative) without truncating the values currently inside</p>

myWriter.Write(txtFilePath.Text);
myWriter.Close();
}
}

{
string[] myFiles = Directory.GetFiles("C:\\");
foreach (string filename in myFiles)
{
