<p>Other things to consider:</p>

<li>I would call my javascript expertise as intermediate. </li>
<li>I'd like to find a book that is as up to date with the jquery platform as possible as I know that in a few months it will likely be out of date.</li>

Each iteration outputs the time that the appointment begins, along with the amount of the time available for the director to carry out the interview. When the queue becomes empty, the time for the last interview is the difference between the office-closing time of 5:00 pm. and the prior starting time for the last interview.</p>

166,836 | 166,837 | URLSpan on Spanned Text not showing in drawn StaticLayout | <p>I'm building a custom view that mimics TextView but which supports text wrapping by managing multiple internal StaticLayouts.</p>
<p>Everything is working out quite well, but I'm having trouble with viewing some HTML. Most of the HTML markup is translated to Spans via <code>Html.fromHtml</code>. This includes the a-link elements which, when I step through with the debugger, I can see are becoming URLSpan objects.</p>
<pre><code> mSpannedArticleText = Html.fromHtml(mInboundArticleText);
</code></pre>
<p>In the above, mInboundArticleText is the inbound string passed to setText and mSpannedArticleText is the Spanned object which will be passed to the StaticLayout. Everything in the StaticLayout renders great except <em>I cannot see the URLSpans.</em> I know they are attached to the mSpannedArticleText and I create a new StaticLayout using:</p>
<pre><code>updatedLeftColumnLayout = new StaticLayout(mSpannedArticleText, mBodyTextPaint, leftColumnWidth, Layout.Alignment.ALIGN_NORMAL, (float) 1.0, (float) 0.0, true);
</code></pre>
<p>I'm not sure what would be causing this issue but, after looking at the source code for TextView, I can't seem to locate any special handling of URLSpans, nor do I see any exception cases in StaticLayout. I'm hoping someone can shed some light on what I might be doing incorrectly in building the Spanned text or other requirements for using URLSpans which I might not have setup.</p>

98,568 | 98,569 | android location listener question | <p>I am developing an location aware application that needs to know the users location.
The problem is that the application doesn't seem to work properly.</p>
<p>By properly I mean that every time I have to first open an application (like cardio trainer) in order to get a GPS signal and then run my program, otherwise the GPS icon on the notification bar is blinking like it blinks when the device tries to get GPS signal and after a while it stops and no location is returned!</p>
<p>this is really weird because it shouldent stop, is there an interval that android provides the gps to get signal?</p>
<p>on the documentation I haven't found anything about that.</p>
<p>my code is as follows:</p>
<pre><code>lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 60000, 10, locationListenerGps);
LocationListener locationListenerGps = new LocationListener() {
public void onLocationChanged(Location location) {
locationResult.gotLocation(location);
Log.e("##################","MyLocation got GPS location accuracy:
"+location.getAccuracy()+" Altitute: "+location.getAltitude()+" log:
"+location.getLongitude()+" lat: "+location.getLatitude());
}
public void onProviderDisabled(String provider) {}
public void onProviderEnabled(String provider) {}
public void onStatusChanged(String provider, int status, Bundle extras) {}
};
</code></pre>
<p>That should open the gps provider and register a listener called locationListenerGps that would be called by the location manager every 1 minute or 10 meters right?</p>
<p>why I have to open cardioTrainer first to get a GPS signal?</p>
<p>thanks in advanced maxsap </p>

1,237,302 | 1,237,303 | Passing a const vector<pointers> to a method but changing value pointed to | <p>I have following code (only relevant portions shown for sake of brevity - please let me know if I have been too brief):</p>
<pre><code>class my_class

public:
my_class() {m_i=0;}
set(int i) {m_i = i;}
private:
int m_i;
}
void CallMod()
{
// create a bunch of my_class* o = new my_class() and store in vector<my_class*>

}
void Mod(vector<my_class*> const & vObject)
{
BOOST_FOREACH(my_class o, vObject)
{

}
}

<p>Does this mean that while vObject is const, the modification done by the call to o->set(2) will be retained once Mod returns? Does that indicate that the "const" qualifier will not allow modify operations on vObject (i.e. the vector) but allows modification on the contained pointers to my_class?</p>
<p>Did I understand this right? Any duplicate questions that answers this - I couldn't find one - links most appreciated.</p>

1,861,429 | 1,861,430 | What should I do to practice? | <p>I start a year long industrial placement in September where i will be coding in Java predominantly. I am going to use the summer to brush up on my Java as in year one of the degree Java was the main language taught for OOP modules. However this year i have had no Java exposure except for an algorithms module, which was one of eight, so as you can see i am probably getting really rusty!.</p>
<p>What i wanted to know is, how does the "real world" java programming differ from university coding and what do you suggest i brush up on that would be different to my normal workings. As a start I definitely need to get familiar with a professional IDE like NetBeans, opposed to having used BlueJ throughout but more specifically what coding practices should I get more familiar with.</p>
<p>I appreciate they wont expect me to be a qualified full developer and will give me time, but I would like to hit the ground running as it were, with me having full hopes to secure a permanent position after I finish my degree.</p>
