I'm working in a 12 year old code base which I have been the only developer on.
There are times that I'll make a a very small change based on an intuition (or quantum leap in logic ;-).
Usually I try to deconstruct that change and make sure I read thoroughly the code.
However sometimes, (more and more these days) I just test and make sure it had the effect I wanted. (I'm a pretty thorough tester and would test even if I read the code).
This works for me and we have surprisingly (compared to most software I see) few bugs escape into the wild.
**But what I'm wondering is whether this is just the "art" side of coding.** Yes, in an ideal world you would exhaustively read every bit of code that your change modified, but I in practice, if you're confident that it only affects a small section of code, is this a common practice?
I can obviously see where this would be a disastrous approach in the hands of a poor programmer. But then, I've seen programmers who ostensibly are reading the code and break stuff left and right (in their own code based which only they have been working on). | proramming | null | null | null | null | null | open | Do you ever make a code change and just test rather than trying to fully understand the change you've made?

While I am debugging I can step through the program with ease up until I reach the following snippet of a block of code.
ENUM_START_TYPE My_Class::some_function( const char * c, const char * e)
{
ENUM_START_TYPE result = GENERIC_ENUM_VALUE;
if ( c[0] == '<' )
{
result = do_something()
}
...
MORE CODE
...
return result;
}
When the debugger reaches this line.
if ( c[0] == '<' )
It starts exploring sections of code that it can not find until it opens a tab containing the /projectname/.metadata and simply declares:
"Resource '/project_name/.metadata' does not exist.
At which point the debugger terminates the program with no reason as to why.
All I wish to do is step over this line of code because it really is as trivial as comparing characters.
My question is: Why is this happening? Is it something to do with the debugger, or does it have something to do with my code, or what. Additionally, what is the .metadata and why can't the file be located and opened when it clearly exists.
Other info that may be pertinent: The files are located on a clearcase snapshot view, but are not checked into source control. I don't think that would cause an error like this, but clear case has caused so many random errors for me that I thought it would be worth mentioning.

2. We don't use private methods, ever.
In order to take advantage of our mocking framework (RhinoMocks) the methods can't be private. This has been the biggest one to "sell" to our traditional devs. And to some degree I see their point. I just value testing more.

What do I mean? Well, I have to deal with a fairly huge web-app. Tons of Ajax requests are fired in different modules. Now, my goal is to implement a simple session-timeout mechanism. Each request sends the current session-id as parameter, if the session-id is not valid anymore, my backend script returns the request with a custom responser-header set (value is a uri).
So I'm basically going like this
window.jQuery && jQuery( document ).ajaxComplete(function( event, xhr, settings ) {
var redirectto = xhr.getResponseHeader( 'new_ajax_location' );
if( redirectto ) {
location.href = redirectto;
}
});
This does work like a charm of course, but my problem is that this global ajax event actually needs to get fired first 100% of the time, which is not the case. Some of those original ajax-requests handlers will throw an error because of missing or unexpected data, in that case, the global handler never gets executed.
Now, I'd be kinda happy if I wouldn't need to go through every single request handler and make it failsafe for invalid session data responses. I'd much more prefer to do the job at one particular place. But how can I make sure my global handler will get executed first ? | javascript | jquery | ajax | null | null | null | open | jQuery - set Ajax handler priority

the ability to add third party modules later on - hooks

***Insertion Sort***
Lets start with Insertion Sort. I understand how Insertion Sort works but would like to clarify if I am understanding it correctly. Insertion Sort "brute forces" the array or whatever it is sorting. It starts from the very left position and the position after that. It sorts those two and keeps continuing until the whole array has been sorted. Here is the example in my head:
[1] [5] [2] [58] [5] [27] [25]
^ ^
[1] [5] [2] [58] [5] [27] [25]
^ ^
[1] [2] [5] [58] [5] [27] [25]
[1] [2] [5] [58] [5] [27] [25]
^ ^
and so forth until it reaches
[1] [2] [5] [5] [25] [27] [58]
***Quick Sort:***
This is the one I understand the least and would like some clarification. The easiest way for me to understand this was watching this video: http://www.youtube.com/watch?v=ywWBy6J5gz8. From my understanding, a pivot point is chosen, most likely the median as it is the easiest and sorts. Choosing a bad pivot can lead to worse big oh behavior because of the number of inversions it has to make.

merge the two arrays
Where does recursion take place? Sample code?
I believe this is how it works, PLEASE correct me if I am wrong.
***Merge Sort***
This one makes the most sense to me, split the array up until you you can't do it anymore. So array.length/2. Then this is where the confusing part sets in. You have the main array and you begin to sort, you start sorting from the very beginning through the array, two pieces at a time. Where do you determine how to iterate through the array, how do you determine your starting point and ending points when you are going through your array? Then you create a temp array and store it. This one is by far the hardest to explain so please forgive me. I looked at the wiki page for a better example for merge sort and it does a great job, but im just confused as to how it iterates through the main array and sorts it.
***Queue and Stack***
After researching for a bit, I understand what these are. The one thing I haven't been able to look up is, what kind of Big Oh behavior do each of its techniques use?
for a stack this is what I THINK it is: Enqueue is constant, Dequeue is constant, and peek is constant
for a queue: Enqueue is constant, Dequeue is linear, and peek is linear.
if someone could clarify any of these things, or have any picture examples, I would greatly appreciate it,
Thank you.

After each win or loss, I want the neural network (or other algorithm) to update in response to the error of the loss (how this is calculated is unimportant here).
Weka is very nice and I don't want to reinvent the wheel. However, Weka's API seems primarily designed to train from a dataset. Game playing doesn't use a dataset. Rather, the network plays, and then I want it to update itself based on its loss.
Is it possible to use the Weka API to update a network instead of a dataset but on one instance and do this over and over again? I'm I thinking about this right?
The other idea I also want to implement is use a genetic algorithm to update the weights in a neural network, instead of the backpropogation algorithm. As far as I can tell, there is no way to manually specify the weights of a neural network in Weka. This, of course, is vital if using a genetic algorithm for this purpose.

Further when I check in a few files, the pending changes view is refreshed and all the items are expanded and is selected. Considering there are multiple solutions in the workarea (which are functionally and logically disjoint) and at any time I could be working on multiple tracks, the auto refresh, expand and select forces me to go through each node and collapse and deselect it.
A bit of searching brought me to this [page][1] where there specify a workaround to have the Hierarichal view selected by default using macros. Extending this method to resolve the above issue didn't materialize as I believe the events of node collapse and deselection are not getting recorded.

If someone has a clue or sample code I'd really appreciate it.
Thanks
Shiva.

The problem is that that there are many other applications under the same folder in IIS, and these other apps don't need to use and don't know (mustn't know) about this handler.
However, the Web.Config in which I register it ends up applying to all folders on the same level and all subfolders, and this is what I want to avoid.
Changing the structure of the apps inside IIS is not a possibility, unfortunately.
I thought of using the < location > tag on Web.config, but I'm under the impression it only changes rights to access and not visibility.
Any suggestions on how this can be overcome? | .net | asp.net | iis | httphandler | null | null | open | Can I limit an ASP.net HttpHandler scope?

I'm still working on my program with the Airline class. The Airline class contains a vairable to an array of dynamic Flight objects.
In the Airlines class I have (which can't be edited or changed, these are the header files given to me for the assignment):
//Airline.h
class Airline {
public:
Airline(); // default constructor
Airline(int capacity); // construct with capacity n
void cancel(int flightNum);
void add(Flight* flight);
Flight* find(int flightNum);
Flight* find(string dest);

int capacity; // maximum number of flights
int size; // actual number of flights
void resize();
};
---
//Flight.h
class Flight {
public:
Flight();
// Default constructor
Flight(int fnum, string destination);
void reserveWindow();
void reserveAisle();
void reserveSeat(int row, char seat);
void setFlightNum(int fnum);
void setDestination(string dest);
int getFlightNum();
string getDest();
protected:
int flightNumber;
bool available[20][4]; //only four seat types per row; only 20 rows

};
I'm trying to impliment the add() method.
for that, I have:
/* Flight **array; // dynamic array of pointers to flights

*/
void Airline::add(Flight* flight){
if(size == capacity){
resize();
}
//Flight* newFlight = new Flight;
array[size] = flight; //This is where I get the EXC BAD ACCESS error
size++;
}
I don't understand why I'm getting this error. I'm assigning the address to the flight I created to the array. Am I not assigning it correctly?
Also, I'm not sure I created this resize method correctly:
void Airline::resize(){
Flight **temp = new Flight*[capacity * 2];
Flight **swapper;
for(int i = 0; i < capacity; i++){
temp[i] = array[i];
}
swapper = temp;
temp = array;
array = swapper;
delete [] temp;

}
// resizes the array if it exceeds capacity. New array is double size of old array.

I'm having issues when panning the drawing. What I would like to do is to create a bitmap that's 3x as wide as the drawing window & 3x as high. Then, when the user begins to pan, I would render the part of the bitmap that should be visible.
Trouble is, it doesn't appear as though you can have bitmaps bigger than your render target. Here's approximately what I've done so far:
// Get the size of my drawing window.
RECT rect;
HDC hdc = GetDC(hwnd);
GetClipBox(hdc, &rect);
D2D1_SIZE_U size = D2D1::SizeU(
rect.right - rect.left,
rect.bottom - rect.top
);
// Now create the render target
ID2D1HwndRenderTarget *hwndRT = NULL;
hr = m_pD2DFactory->CreateHwndRenderTarget(
D2D1::RenderTargetProperties(),
D2D1::HwndRenderTargetProperties(hwnd, size),
&hwndRT
);
// And then the bitmap render target
ID2D1BitmapRenderTarget *bmpRT = NULL;
// We want it 3x as wide & 3x as high as the window
D2D1_SIZE_F size = D2D1::SizeF(
(rect.right - rect.left) * 3,
(rect.bottom - rect.top) * 3
);
hr = originalTarget->CreateCompatibleRenderTarget(
size,
&bmpRT
);
// Now I draw the geometry to my bitmap Render target...
// Then get the bitmap
ID2D1Bitmap* bmp = NULL;
bmpRT->GetBitmap(&bmp);
// From here I want to draw that bitmap on my hwndRenderTarget.
// Based on where my mouse was when I started panning, and where it is
// now, I can create a destination rectangle. It's the size of my
// drawing window
D2D1_RECT_U dest = D2D1::RectU(x1, y1, x1+size.width, y1+size.height);
hwndRT->DrawBitmap(
bmp,
NULL,
1.0,
D2D1_BITMAP_INTERPOLATION_MODE_LINEAR,
dest
);
So when I check the size of my bitmap, it checks out OK - it's the size of my bitmap render target, not my hwnd render target. But if I set x1 & y1 to 0, it should draw the top left-hand corner of the bitmap (which is some geometry off the screen). But it just draws the top left-corner of what **is** on the screen.
Does anyone have any experience with this? How can I create a fairly large bitmap, and then render a portion of it on a smaller-sized render target? Since I'm panning, the render will take place on every mouse-move, so it has to be reasonably performant. | c++ | direct2d | null | null | null | 10/20/2011 04:32:07 | too localized | Rendering part of a bitmap using Direct2D
===
I'm in the process of converting a custom CAD software from GDI to Direct2D. I'm having issues when panning the drawing. What I would like to do is to create a bitmap that's 3x as wide as the drawing window & 3x as high. Then, when the user begins to pan, I would render the part of the bitmap that should be visible.
Trouble is, it doesn't appear as though you can have bitmaps bigger than your render target. Here's approximately what I've done so far:
// Get the size of my drawing window.
RECT rect;
HDC hdc = GetDC(hwnd);
GetClipBox(hdc, &rect);
D2D1_SIZE_U size = D2D1::SizeU(
rect.right - rect.left,
rect.bottom - rect.top
);
// Now create the render target
ID2D1HwndRenderTarget *hwndRT = NULL;
hr = m_pD2DFactory->CreateHwndRenderTarget(
D2D1::RenderTargetProperties(),
D2D1::HwndRenderTargetProperties(hwnd, size),
&hwndRT
);
// And then the bitmap render target
ID2D1BitmapRenderTarget *bmpRT = NULL;
// We want it 3x as wide & 3x as high as the window
D2D1_SIZE_F size = D2D1::SizeF(
(rect.right - rect.left) * 3,
(rect.bottom - rect.top) * 3
);
hr = originalTarget->CreateCompatibleRenderTarget(
size,
&bmpRT
);
// Now I draw the geometry to my bitmap Render target...
// Then get the bitmap
ID2D1Bitmap* bmp = NULL;
bmpRT->GetBitmap(&bmp);
// From here I want to draw that bitmap on my hwndRenderTarget.
// Based on where my mouse was when I started panning, and where it is
// now, I can create a destination rectangle. It's the size of my
// drawing window
D2D1_RECT_U dest = D2D1::RectU(x1, y1, x1+size.width, y1+size.height);
hwndRT->DrawBitmap(
bmp,
NULL,
1.0,
D2D1_BITMAP_INTERPOLATION_MODE_LINEAR,
dest
);
So when I check the size of my bitmap, it checks out OK - it's the size of my bitmap render target, not my hwnd render target.

I am storing a CV/resume document in a solr document. I am looking at storing two different data types "education" and "employment"
If we look at education the object looks like this:
{
"establishment" => 'Oxford',
"Subject" => 'Computing',
"Type" => 'Degree',
"Grade" => '2:1
}
A CV can have n+1 of these objects depending on the contents of the CV. The search needs to be able to see that when I search for CV with Establishment = Oxford & Subject = Computing & Grade = 2:1 that it matches this object not a different establishment with the same subject and grade.
A multivalue I don't think would help or is possible to store n+1 of these types of objects.
My question is how to set up solr to be able to store this type of data against one "CV" Solr document so that it is search able as part of a general search of the index?
Thanks,

Currently I solve the problem like that:

localeChangedListener.add(menuData);
The LocaleChangedListener:
public class SwingLocaleChangedListener implements LocaleChangedListener {
private ArrayList<AbstractButton> abstractButtons;
@Override
public void localeChanged(ResourceBundle rb) {
logger.info("Locale changed to '" + rb.getLocale() + "'");
for (AbstractButton b : abstractButtons) {

}

initAbstractButtons();
return abstractButtons.add(b);
}
private void initAbstractButtons() {
if (abstractButtons == null) {
this.abstractButtons = new ArrayList<AbstractButton>();
}
}
}
And the registration of the Listener:
public class GuiBundleManager {
private String filePrefix = "language.lang";
private ResourceBundle rb = null;
private LocaleChangedListener listener = null;
private static GuiBundleManager instance = null;
private GuiBundleManager() {

public String[] getStringArray(String key) {

return listener;
}
public void setLocaleChangedListener(LocaleChangedListener listener) {

listener.localeChanged(rb);
}
}
public static GuiBundleManager get() {
if (instance == null) {
instance = new GuiBundleManager();
}
return instance;
}
}
.
.
An other way I'm thinking of is using Component.setLocale() combined with an PropertyChangedListener:
public abstract class GUIComponentFactory {
public JLabel createLocalisedJLabel(final String key) {
final JLabel label = new JLabel(GuiBundleManager.get().getString(key));
label.addPropertyChangeListener("locale", new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent e) {
label.setText(GuiBundleManager.get().getString(key));
for(Component c : getComponents()){
c.setLocale(e.getNewValue());
}
}
});
return label;
}
.
.
.
}

public static GuiBundleManager get() {
if (instance == null) {
instance = new GuiBundleManager();
}
return instance;
}
}
.
.
An other way I'm thinking of is using Component.setLocale() combined with an PropertyChangedListener:
public abstract class GUIComponentFactory {
public JLabel createLocalisedJLabel(final String key) {
final JLabel label = new JLabel(GuiBundleManager.get().getString(key));
label.addPropertyChangeListener("locale", new PropertyChangeListener() {
@Override
public void propertyChange(PropertyChangeEvent e) {
label.setText(GuiBundleManager.get().getString(key));
for(Component c : getComponents()){
c.setLocale(e.getNewValue());
}
}
});
return label;
}
.
.
.
}
Maybe you have a better solution

When testing in the emulator (and on a phone), the app appears to 'lock up' when the user hits "Submit". It hasn't actually crashed or anything like that, it's just locked whilst the connection to the server is made (and then it advances the user to the next view if their login is correct).
This isn't very cosmetically pleasing as some users may think the app has locked up if their connection is slow and the login doesn't process for a few seconds..
To avoid this I want to have a ProgressBar which will appear just to let the user know something is happening and the app hasn't locked up!
Here's my code:

public void onClick(View v) {
Button submitButton = (Button)findViewById(R.id.submit);
submitButton.setVisibility(8); //Make submit button invisible
ProgressBar progressBar = (ProgressBar)findViewById(R.id.progressbar);
progressBar.setVisibility(0); //Make progress bar visible. It's in the same position as the submit button
login(); // do the login server stuff
// the problem is that thenew visibility doesn't happen until the login() is called...
}
};
I've ordered the code so that it makes the submit invisible, then makes the progress bar visible, then does the login (so the progress bar will be there twirling around whilst the app connects to the login server). However, it's not working out how I intended - it's seemingly skipping over the setVisibility code and just calling the login method. It must be setting the visibility of the submit and progress bar items but it doesn't happen before the login method does its stuff as it just locks up like usual and the items never actually get hidden/shown until the login method has completed!!

I'm currently testing some actions wich require the user to be logged in, but I've noticed that the session gets killed on some browser, but not on others (Internet Explorer keeps session alive, but Firefox doesn't).
Is there a cleaner way to test it other than testing for the session cookie and, if not set, calling to a log-in method?
Currently I'm doing the following:
if(!$this->isCookiePresent('session_cookie')) {
$this->login();
