3,223,058 | 1 | 3,223,163 | null | 0 | 81 | Suppose that we have the following partial ER diagram:
Notice that the `attachments` table will subsequently be used for the messages', submissions', assignments', and lectures' attachments.
The problem is with the 3 one-to-one relationships between `attachments` and `messages`, `submissions`, and `assignments`. According to CakePHP's conventions, `Message belongsTo Attachment` (and `Attachment hasOne Message`) because `Message` contains the foreign key (the same thing applies to the other 2 relationships). Of course, it makes more sense to say that `Message hasOne Attachment` (and that `Attachment belongsTo Message`). If we only had `messages` and `attachments`, it would be easy to "" the relationship by moving the foreign key to `attachments`.
But the problem again is that `messages`, `submissions`, `assignments`, and `lectures` have relationships with the same `attachments` table. One way to get the "" relationships is to have 4 different `Attachment` models: `MessageAttachment`, `SubmissionAttachment`, `AssignmentAttachment`, and `LectureAttachment`.
Assuming we are only interested in retrieving the attachment of a certain message, submission, or assignment, `Attachment`

3,224,434 | 1 | 3,224,886 | null | 0 | 1,439 | Im posting from my phone so please excuse stupid typos and formatting issues.
I have an activity which lists saved games that the player can load.
I created a simple layout xml file which defines a ScrollView. On load, I grab all the saved games and programatically add a view for each saved game to a vertically oriented LinearLayout child of the ScrollView.
The view for each game consists of a Horizontally oriented LinearLayout which in turn contains a Button and a vertically oriented LinearLayout. That LinearLayout in turn contains some TextViews and ImageViews (and one more LinearLayout which I'm ommitting here for the sake of clarity).
The hierarchy looks something like this (some details omitted).
```
ScrollView
LinearLayout - vertical
Each saved game:
LinearLayout - horizontal
Button - load game
LinearLayout - vertical
TextView - game name
TextView - date string
```
I would like the top of the button and the "game name" texview to be vertically aligned but the TextView (or maybe it's LinearLayout parent) has some rogue padding on top that I can't get rid of. See screenshot for details.
LoadSaved class:
Note: mScrollView is badly named. It refers to the ScrollView's child LinearLayout.
```

I'm using [Wampserver](http://www.wampserver.com/) to run my PHP scripts, and I wanted to do unit tests. So I found PEAR.
I tried installing via the go-pear.bat file, but that didn't work.
I found out more about this here: [http://blog.pear.php.net/2009/07/01/php-53-windows-and-pear/](http://blog.pear.php.net/2009/07/01/php-53-windows-and-pear/)
So I downloaded the php file. The comments in the file suggest I
> Put go-pear.php on your webserver,
where you would put your website
I find this a little strange. Still, I put it in the folder along with the other php files. Here's what I was presented with:
Maybe it is because I'm not very experienced with this, but I would initially believe I should put PEAR in a central location, using 1 pear install for all possible future projects.
Or is this the prefered configuration? And why?

I modified the color.py so that it can run independently from the SciPy source and it all to work fine - values in the array are changed when I run conversions.
My problem is that when I run the above code which simply converts an image to Lab, then back to RGB and saves it I get the following image back:

[source](https://www.tommti-systems.de/go.html?http://www.tommti-systems.de/main-Dateien/reviews/languages/benchmarks.html) Trying to find an updated benchmark.
C#'s integer and double performance is damn close to C++ compiled with MSVC++. 87% as fast for double and 99% as fast for 32-bit integer. Pretty damn good, I'd say. But then look at matrix multiplication. The gap widens to C# being about 19% as fast. This is a pretty huge discrepancy that I don't understand. Matrix multiplication is just a bunch of simple math. How is it getting so slow? Shouldn't it be roughly as fast as an equivalent number of simple floating point or integer operations?
This is especially of a concern with games and with XNA, where matrix and vector performance are critical for things like physics engines. Some time ago, Mono added support for SIMD instructions through some nifty vector and matrix classes. It closes the gap and makes Mono faster than hand-written C++, although not as fast as C++ with SIMD.

[](https://i.stack.imgur.com/130dt.png)
What's going on here?
Edit: Looking closer, I misread the second graph. C# appears pretty close. Sorry, I missed the version number on the first benchmark. I grabbed it as a handy reference for the "C# linear algebra is slow" that I've always heard. I'll try to find another.

I need an algorithm that determines such position of the circle that it covers maximal possible number of points. Of course, there are many such positions, so the algorithm should return one of them.
Precision is not important and the algorithm may do small mistakes.
Here is an example picture:
Input:
`int n` (n<=50) – number of points;
`float x[n]` and `float y[n]` – arrays with points' X and Y coordinates;
`float r` – radius of the circle.
Output:
`float cx` and `float cy` – coordinates of the circle's center
Lightning speed of the algorithm is not required, but it shouldn't be too slow (because I know a few slow solutions for this situation).
C++ code is preferred, but not obligatory.

Assuming I had the intersection points, I could project to 2D and use a point-line-side (or triangle signed area) test to determine the orientation of a triangle between any 3 intersection points.
The problem is I can't explicitly compute the intersection points because of the floating-point error that accumulates when I find the line-plane intersection. To figure out if the line segments strike the triangle in the first place, I'm using some freely available robust geometric predicates, which give the sign of the volume of a tetrahedron, or equivalently which side of a plane a point lies on. I can determine if the line segment endpoints are on opposite sides of the plane through the triangle, then form tetrahedra between the line segment and each edge of the triangle to determine whether the intersection point lies within the triangle.
Since I can't explicitly compute the intersection points, I'm wondering if there is a way to express the same 2D orient calculation in 3D using only the original points. If there are 3 edges striking the triangle that gives me 9 points in total to play with. Assuming what I'm asking is even possible (using only the 3D orient tests), then I'm guessing that I'll need to form some subset of all the possible tetrahedra between those 9 points. I'm having difficultly even visualizing this, let alone distilling it into a formula or code. I can't even google this because I don't know what the industry standard terminology might be for this type of problem.
Any ideas how to proceed with this? Thanks. Perhaps I should ask MathOverflow as well...
EDIT: After reading some of the comments, one thing that occurs to me... Perhaps if I could fit non-overlapping tetrahedra between the 3 line segments, then the orientation of any one of those that crossed the plane would be the answer I'm looking for. Other than when the edges enclose a simple triangular prism, I'm not sure this sub-problem is solvable either.

What I would like to do is allow the page to have it's width determined by the `<body>` tag and a top level `.page` style that I've defined in my css. My site has a left navigation pane that is ALWAYS a certain width. The "content" area stretches with the page and should determined by the remaining space that consumes the users screen.
I'd like to show scrollbars on content that does not "keep the peace" with my floating area width. For example, I've recently come upon a series of sub elements that need scrollbars displayed to keep the page from stretching off into eternity.
Here is a simple image of how things look when scrollbars aren't needed:
Here is what it looks like when my sub content is wider than the page:
What I'd like to do is show scrollbars on the red sections when they fulfill their allowed space (including margins and padding). I would like for everything to be padded nicely against the blue section so that the yellow and white sections don't get overlapped.

```

3,239,120 | 1 | 3,243,276 | null | 8 | 6,511 | This is a fairly lengthy (not overly complex) design question so please bear with me. I'm trying to implement a person/role management system with POJOs and JPA. I'm fairly new to ORM and this is mostly a mapping problem.
I've got this working as POJOs and am comfortable with the caller-level API, but would now like to map it to a database using JPA or Hibernate in a Seam environment.
My implementation is based on the Decorator (GoF) and Person Role Object patterns (Baumer/Riehle et al). All roles are hard-coded and run-time addition of new roles is not supported since it would require code changes to extend behavior. I'd use user groups to implement security and permissions.
There is a Person interface with role management methods such as addRole(), removeRole(), hasRole(), getRole(), getRoles(), among other things. The concrete implementation is provided by a PersonImpl class.
There is an abstract class Role which also implements the Person interface (for decorator substitution equivalence), and a RoleImpl class that extends it. The Role class holds a reference to a person instance, using it to service any method / property calls on the person interface, meaning all subclasses of Role can handle the Person interface. The role constructor takes the person object as a parameter.
These are the interfaces/classes:
```
public interface Person {
public String getFirstName();
public void setFirstName(String firstName);
.
.
.
public boolean isEnabled();
public void setEnabled(boolean enabled);
public Set<Role> getRoles();
public Role addRole(Class<? extends Role> roleType);
public void removeRole(Class<? extends Role> roleType);
public boolean hasRole(Class<? extends Role> roleType);
public Role getRole(Class<? extends Role> roleType);
public enum Gender {MALE, FEMALE, UNKNOWN};
}
public class PersonImpl implements Person {
.
.
.
}
public abstract class Role implements Person {
protected PersonImpl person;
@Transient
protected abstract String getRoleName();
protected Role() {}
public Role(PersonImpl person) {
this.person = person;
}
public String getFirstName() {
return person.getFirstName();
}
public void setFirstName(String firstName) {
person.setFirstName(firstName);
}
public Set<Role> getRoles() {
return person.getRoles();
}
public Role addRole(Class<? extends Role> roleType) {
return person.addRole(roleType);
}
.
.
.
}
public abstract class RoleImpl extends Role {
private String roleName;
protected RoleImpl() {}
public RoleImpl(PersonImpl person) {
super(person);
}
.
.
.
}
public class Employee extends RoleImpl {
private Date joiningDate;
private Date leavingDate;
private double salary;
public Employee(PersonImpl person) {
super(person);
}
.
.
.
}
```
This diagram shows the class relationships:
(If you can't see the diagram inline, view it here [via yUML](https://yuml.me/diagram/scruffy;dir:lr;scale:80/class/%5BPerson;%3C%3Cinterface%3E%3E%5D%5E-.-%5BPersonImpl%5D,%20%5BPerson;%3C%3Cinterface%3E%3E%5D%5E-.-%5BRole;%3C%3Cabstract%3E%3E%5D,%20%5BRole;%3C%3Cabstract%3E%3E%5D%5E-%5BRoleImpl%5D,%20%5BPersonImpl%5D%3C%3E-%3E%5BRoleImpl%5D,%20%5BPersonImpl%5D%3C-%5BRoleImpl%5D,%20%5BRoleImpl%5D%5E-%5BEmployee%5D,%20%5BEmployee%5D%5E-%5BTeacher%5D,%20%5BEmployee%5D%5E-%5BPrincipal%5D,%20%5BEmployee%5D%5E-%5BAccountant%5D,%20%5BRoleImpl%5D%5E-%5BParent%5D,%20%5BRoleImpl%5D%5E-%5BStudent%5D))
I'd use these classes like so:
```
Person p = new Person("Doe", "John", Person.MALE, ...);
// assuming Employee extends Role
Employee e = (Employee)p.addRole(Employee.class);
```
Since the Role class also implements the Person interface, I can also do:
```
// assuming Parent extends Role
Parent parent = new Parent((PersonImpl)p);
e.addRole(Parent.class);
e.getDateOfBirth(); // handled by the decorated person class
// assuming Manager extends Employee extends Role
Manager m = (Manager)p.getRole(Manager);
if (m.hasRole(Employee.class) {
// true since Manager derives from Employee
}
```
The questions I have are:
(a) Is this implementation needlessly complex and if so what would be a simpler approach? Note that this goes into a non-trivial business application and not a kiddy project, and I think the role subclassing is important to leverage behavior in cases such as Employee, Manager, etc.
(b) How do I map this in JPA/Hibernate?
(c) Can it be mapped so I can also take advantage of Seam Identity Management? (My definition of Role is clearly not analogous to Seam's)
(d) If I go with a table-per-subclass (InheritanceType.JOINED) mapping strategy, I map PersonImpl as PERSONS and RoleImpl as ROLES tables, and map each subclass of RoleImpl (such as Employee and Parent) to their own tables as EMPLOYEES and PARENTS.
I would then have a @ManyToMany relationship between PERSONS and ROLES (on the roles collection in PersonImpl), with the join-table PERSON_ROLES.
Now the problem is that the EMPLOYEES and PARENTS tables, etc. have only the ROLE_ID reference, since the inheritance mapping strategy obviously considers them to be extensions to Roles (ROLES) whereas I need them as addendum to PERSON_ROLES, and require the USER_ID + ROLE_ID key to be resolved properly, or at least the USER_ID.
I would prefer a normalized database with the attendant reliance on extra joins than a denormalized database which will be difficult to maintain and likely bunch up a ton of unused and irrelevant fields, which is why I think table-per-subclass is the way to go.
Or is a table-per-class-hierarchy (InheritanceType.SINGLE_TABLE) with a discriminator column OK (from database maintenance perspective) in this scenario? Note that some roles are likely to have dozens of properties/fields.
(e) Is there a better alternative to this design?
Would very much appreciate any ideas/suggestions.

3,240,900 | 1 | 3,240,993 | null | 3 | 358 | At work, we use Perforce for version control. There are problems with this: 1) with this centralized model, we can't check in changes until they are ready for regression. This means that we have no revision control during the development process. 2) We don't back up our client view of the depot, so our work is unsafe until we can check it in. 3) We have problems sharing our code with each unless we beg to have an integration branch set up. I am trying to set up an optional git workflow for developers who want to use git to beat these problems.
The plan is to use git-p4 to interface with the perforce server and create a private git repo. This takes care of 1). I plan to use the integration-manager workflow depicted in Git Pro ([http://progit.org/book/ch5-1.html](http://progit.org/book/ch5-1.html)) to have our developers publish public repos, taking care of 3).
Finally, I want a place where developers can push their changes so that they will pulled into nightly backups / offsite backups. The reason we don't backup our client views now is because doing nightly archival backups of everyone's client view is space inefficient. We have a lot of developers, and they produce a lot of code. We can't be redundantly backing up everyone's client view. We only want to preserve the only.
My thinking was to have one bare git repo, call it `omni-backup`, that everyone can push all of their branches to (and feel free to suggest alternatives). This would utilize git's space efficient sha-1 hashing and ensure that only unique versions of each file are backed up. The trick is that all the backup repositories have to be part of the same repo to get the space efficiency.
The problem is when two people with completely different branches chose the same name for their branch. E.G. Bob has a `feature` branch and Jane has a `feature` branch, but they're for different features. If Bob pushes to omni-backup, Jane won't be able to, as it wouldn't be a fastforward merge.
Now what I would ideally want to have happen is that when Bob pushes his feature branch, the branch will be renamed to `bob-feature` on the `omni-backup` remote. And when he pulls feature from `omni-backup`, he gets back `bob-feature`.
This doesn't seem terribly easy to accomplish in git. It looks like I can use push hooks documented in [http://www.kernel.org/pub/software/scm/git/docs/git-receive-pack.html](http://www.kernel.org/pub/software/scm/git/docs/git-receive-pack.html) post-receive hook to rewrite the name of the ref immediately after it written, and then could be done to reverse the process on the way back, but it feels fragile. Anyone have a better idea?

edit: for VonC (Because code sucks in comments)
Your way sounds promising, VonC, but I don't see how the fact that it's a fetch will beat the namespacing problems. Are you suggesting a cronjob that knows how to rename the branch?

my @branches = split(/s/,cat `$LDAPSERVER/$USER/$REPO/.git/refs/heads`);

I want to have a view, and to be able to add a circle at any coordinate. As soon as I add the circle it should expand at a predefined rate; I'd also like to repeat this process and have a number if these expanding circles.
Think Missile Command:
Generally, if I was writing this in C++ using SDL or some other graphics library I would:
Have a class to represent an 'growing circle'
Have a vector/array to hold pointers to all the 'growing circles' I create.
All circles diameters would be increased each tick, and in my renderloop I would iterate the list and draw appropriate circles to my buffer.
This, however, doesn't seem to fit well with how I've generally used views in previous iPhone development.
So I guess it's kind of open-ended, but is there a 'correct' way for something like this?
Would it be in a game loop style (as described above), or should I be subclassing `UIView` for a 'circle' object, and override `drawRect`? I guess I would then have to add each circle by creating a view and adding it to my main view?
Initial investigation also brought me across references to the [CAShapeLayer](http://developer.apple.com/iphone/library/documentation/GraphicsImaging/Reference/CAShapeLayer_class/Reference/Reference.html) class, though I'm guessing this might be much the same as implementing the UIView subclassing technique.

So as the image scale, B needs to move relative to C. Example: if the image was scaled 50%, then B would move 1/2 the distance to C. If the image grew to 200% of its size, then B would move twice the distance away from C.
Ultimately looking for a formula for x & y for B given the location of C and a scaling factor for the image. Not sure the size of the image needs to be part of this but I have it if needed.
Thanks for any help!
Things I know:
1. I know the width and height of the image rectangle.
2. I know the offset of B from A.
3. I know the offset of C from A.
4. I know the scale factor in percent of the image.

3,247,065 | 1 | 3,247,242 | null | 4 | 1,688 | I am trying to do the design of a [Bejeweled](http://en.wikipedia.org/wiki/Bejeweled) game. I have basically 3 classes. The `Game` class, which is what is going to be used by the player, a `Board` class, that represents the board, and a `SwitchController` class that is responsible for checking if the wanted switch on the board is valid, making the switch, counting the number of possible switches available (so I can know when the game is over, etc).
My current design is something like the following:
```
Game:
isGameOver()
isSwitchValid(coord1, coord2)
makeSwitch(coord1, coord2)
getPieceAt(coord)
getBoardLength()
IBoard:
getPieceAt(coord)
setPieceAt(coord, piece)
getLength()
```
My idea would then to have a `ISwitchController`:
```
ISwitchController:
isSwitchValid(coord1, coord2)
makeSwitch(coord1, coord2)
getAllValidSwitches()
```
Here is a little diagram of how the classes are to be organized:
I would have 2 different concrete classes of `IBoard` available for use (and for each one of them, I'd have to have an `ISwitchController` implementation).
## The problem:
My program is to have 2 IBoard implementations:
The first, `ArrayBoard`, will have all the pieces of the board stored in a 2D Array. There is nothing special about it. I will define an `ArrayBoardSwitchController` for managing this class.
The second, `ListBoard`, will have for each color of pieces, a List/Set with all the coordinates of the pieces of that color. I will define a `ListBoardSwitchController` for managing this class.
The main issue here is that the implementation of `SwitchController` will be totally different on `ArrayBoard` and on `ListBoard`. For example, while for implementing `getAllValidSwitches()` `ArrayBoardSwitchController` only needs the `getPieceAt()` method, that would not be a good idea to do with `ListBoardSwitchController`(in that class I use internally lists because it's easier to check if the move is valid that way).
From what I can see, there are 2 different possible solutions:
1. I could either merge together the ISwitchController and IBoard interfaces. That way I'd only have two classes, Game and Board (while basically Game would just be a controller for the Board, as it would be the Board that had all the game logic). It wouldn't be that nice because the classes wouldn't be as cohese as they could be if I had 3 distinct classes.
2. Let the interfaces as they are and put all the methods I need to work with public in the concrete classes. For example, if I need a getYellowPiecesList() method, I'd put it public on ListBoard so ListBoardSwitchController could use it. ListBoardSwitchController would only know about it because it knows it only works against ListBoards.
What's your opinion on the matter?

The flowchart for all of these steps is large and complicated, and three people might be working on three completely different steps at any one time.
How would you present this vast amount of information as usefully as possible to your users? Just showing the whole diagram seems like the brute force solution. But it's big, and it'll likely get bigger as we do more things. Not to mention the complexity necessary to encode this entire diagram in HTML.

3,257,204 | 1 | 3,258,948 | null | 3 | 597 | Say I want to animate a ball rolling 1000 pixels to the right, specifying a timing function in the process – something like this:
```
UIView *ball = [[UIView alloc] initWithFrame:CGRectMake(0,0,30,30)];
CABasicAnimation* anim =
[CABasicAnimation animationWithKeyPath:@"transform.translation.x"];
anim.toValue = [NSNumber numberWithFloat:ball.frame.origin.x + 1000.0];
// move 1000 pixels to the right
anim.duration = 10.0;
anim.timingFunction = [CAMediaTimingFunction functionWithControlPoints:
0.1 :0.0 :0.3 :1.0]; // accelerate fast, decelerate slowly
[ball.layer addAnimation:anim forKey:@"myMoveRightAnim"];
```
is to have a method, say `-(void)animationProgressCallback:(float)progress`, be called during the animation, in regular intervals of the animation's progress , i.e. ignoring the timing function.
I'll try to explain with the above example with the ball rolling 1000px to the right (charted by the y axis, in our case 100%=1000px):
I want my callback method to be invoked whenever the ball has progressed 250 pixels. Because of the timing function, the first 250 pixels might be reached in ti=2 seconds, half the total distance reached just ti= 0.7 seconds later (fast acceleration kicks in), the 750px mark another ti= 1.1 seconds later, and needing the remaining ti= 5.2 seconds to reach the 100% (1000px) mark.
If the animation called a delegate method in animation-progress intervals as described, I wouldn't need to ask this question… ;-)
One solution I can think of is to calculate the bezier curve's values, map that to the ti values (we know the total animation duration), and when the animation is started, we sequentially perform our `animationProgresssCallback:` selector with those delays manually.
Obviously, this is insane (calculating bezier curves manually??) and, more importantly, unreliable (we can't rely on the animation thread and the main thread to be in sync – or can we?).
Looking forward to your ideas!

3,258,136 | 1 | 3,258,196 | null | 7 | 1,742 | In my latest ASP.NET MVC 2 application I have been trying to put into practice the concepts of [Domain Driven Design (DDD)](http://en.wikipedia.org/wiki/Domain-driven_design), the [Single Responsibility Principle (SRP)](http://en.wikipedia.org/wiki/Single_responsibility_principle), [Inversion of Control (IoC)](http://devlicio.us/blogs/billy_mccafferty/archive/2009/11/09/dependency-injection-101.aspx), and [Test Driven Development (TDD)](http://en.wikipedia.org/wiki/Test_driven_development). As an architecture example I have been following Jeffery Palermo's "[Onion Architecture](http://jeffreypalermo.com/blog/the-onion-architecture-part-1/)" which is expanded on greatly in [ASP.NET MVC 2 in Action](https://rads.stackoverflow.com/amzn/click/com/193518279X).
While, I have begun to successfully apply most (some?) of these principles I am missing a key piece of the puzzle. I am having trouble determining the best mechanism for auto-wiring a service layer to my domain entities.
As an example: each domain entity that needs the ability to send an email should depend on an `IEmailService` interface. From my reading, best practice to reveal this dependency would be to use constructor injection. In my UI layer I perform a similar injection for repository interface implementations using the `StructureMapControllerFactory` from [ASP.NET MVC Contrib](http://mvccontrib.codeplex.com/).
Where I am confused is what is the best mechanism for auto-wiring the injection of the necessary services into domain entities? Should the domain entities even be injected this way? How would I go about using `IEmailService` if I don't inject it into the domain entities?

I have a 2D view, and I have a number of rectangles within an area on the screen. How do I spread out those boxes such that they don't overlap each other, but only adjust them with minimal moving?
The rectangles' positions are dynamic and dependent on user's input, so their positions could be anywhere.
Attached images show the problem and desired solution
The real life problem deals with rollovers, actually.
Answers to the questions in the comments
1. Size of rectangles is not fixed, and is dependent on the length of the text in the rollover
2. About screen size, right now I think it's better to assume that the size of the screen is enough for the rectangles. If there is too many rectangles and the algo produces no solution, then I just have to tweak the content.
3. The requirement to 'move minimally' is more for asethetics than an absolute engineering requirement. One could space out two rectangles by adding a vast distance between them, but it won't look good as part of the GUI. The idea is to get the rollover/rectangle as close as to its source (which I will then connect to the source with a black line). So either 'moving just one for x' or 'moving both for half x' is fine.

I would like all the cells, except the first one to be deletable. The problem is that the default cells have the small delete button on the left side of the cell instead of inside the cell. This causes the cells to shrink to the right, except the first one which keeps its size since it's not deletable.
 
So my question is if there is any way to tweak the default UITableViewCell to have the same behavior as the cell used in the Weather app? Or do I have to implement my own cell with button animation, etc, etc?

What I have in mind is this:
for each face
1. access the face normal
2. get a rotation matrix from the normal vector
3. multiply each vertex to the rotation matrix to get the vertices in a '2d like ' plane
4. get 2 coordinates from the transformed vertices
I don't know if this is the best way to do this, so any suggestion is welcome.
At the moment I'm trying to get a rotation matrix from the normal vector,
how would I do this ?
Here is a visual explanation of what I need:
At the moment I have quads, but there's no problem
converting them into triangles.
I want to rotate the vertices of a face, so that
one of the dimensions gets flattened.
I also need to store the original 3d rotation of the face.
I imagine that would be inverse rotation of the face
normal.
I think I'm a bit lost in space :)

```
All I do is get the current object, access the first face, get the normal, get the vertices, calculate the rotation matrix, invert it, then multiply it by each vertex.
Finally I write a simple output.
Here's the output for a default plane for which I rotated all the vertices manually by 30 degrees:
```
Plane.008
face: [MFace (0 3 2 1) 0]
normal: [0.000000, -0.499985, 0.866024](vector)
original vertex0: [1.000000, 0.866025, 0.500000](vector)
original vertex1: [-1.000000, 0.866026, 0.500000](vector)
original vertex2: [-1.000000, -0.866025, -0.500000](vector)
original vertex3: [1.000000, -0.866025, -0.500000](vector)
rotated vertex0: [1.000000, 0.866025, 1.000011](vector)
rotated vertex1: [-1.000000, 0.866026, 1.000012](vector)
rotated vertex2: [-1.000000, -0.866025, -1.000012](vector)
rotated vertex3: [1.000000, -0.866025, -1.000012](vector)
```
Here's the first face of the famous Suzanne mesh:
```
Suzanne.001
face: [MFace (46 0 2 44) 0]
normal: [0.987976, -0.010102, 0.154088](vector)
original vertex0: [0.468750, 0.242188, 0.757813](vector)
original vertex1: [0.437500, 0.164063, 0.765625](vector)
original vertex2: [0.500000, 0.093750, 0.687500](vector)
original vertex3: [0.562500, 0.242188, 0.671875](vector)
rotated vertex0: [0.468750, 0.242188, -0.795592](vector)
rotated vertex1: [0.437500, 0.164063, -0.803794](vector)
rotated vertex2: [0.500000, 0.093750, -0.721774](vector)
rotated vertex3: [0.562500, 0.242188, -0.705370](vector)
```
The vertices from the Plane.008 mesh are altered, the ones from Suzanne.001's mesh
aren't. Shouldn't they ? Should I expect to get zeroes on one axis ?
Once I got the rotation matrix from the normal vector, what is the rotation on x,y,z ?
1. Blender's Matrix supports the * operator 2.In Blender's coordinate system Z point's up. It looks like a right handed system, rotated 90 degrees on X.

3,275,250 | 1 | 3,278,596 | null | 3 | 669 | My little game project is a physics based platform jobbie created with Chipmunk (via SpaceManager) in Cocos2d.
I wanted something a little different to the a-typical tile mapped level design, so I'm creating levels as SVG files in Illustrator, which I then parse to create the landscape, platforms, spawn points etc etc. It's working pretty well and I feel like I can be as creative as I want with the level design this way.
However, this approach only creates the chipmunk bodies and shapes so far. It doesn't help me when it comes to creating graphics for things like the landscape.
So to illustrate what I'm talking about, a basic level would look a little something like this (scaled down)
[alt text http://www.tomelders.com/bin/leveleg.jpg](http://www.tomelders.com/bin/leveleg.jpg)
The grey areas would represent the landscape.
My first thought was to trace over these levels in Photoshop, and slice them up into 512x512 pngs, which could then be laid on on top of the physics layer. But that instinctively sounds like a very inefficient way to go.
the guys behind Rolando have taken a super simple approach which works well for them
[alt text http://www.handcircus.com/wp-content/uploads/2008/06/rolando_screen_b.jpg](http://www.handcircus.com/wp-content/uploads/2008/06/rolando_screen_b.jpg)
But I would like a bit more detail in my levels, almost similar to what they've achieved in MX Mayhem
Which the more I look at, thew more I'm convinced that they're using the first approach I mentioned of laying large images over the top of everything.
So, my question is, does anyone have any tips or insight into what sort of stuff I should be exploring or reading up on to accomplish this sort of stuff. Up to now, my only experience with creating level graphics in Cocos2d has been with TMXTileMaps. I'm still new to game development so perhaps there's some jargon and terminology to describe what I'm aiming for that I just don't know yet.
Any help or advice is greatly appreciated.
PS: I know question within questions are bad form but it makes sense here: What's the math behind memory usage? Is there a formula I can use to figure out the memory usage of my graphics up front.

I have a drawing procedure (it works) it draws to a bitmap "OBJmap" it then puts OBJmap into Wholemap. This all works but there is a issue. It seems to treat the undefined parts of objmap as white even though objmap and wholemap is set as PF32Bit, and hence when it puts objmap into wholemap I get a white box behind the pasted image that should be transparent.
This only happens on ATI machines, but this is for schools and they all have 100% ati because they are cheap (im not biased honest), so I was recommended to use AggPas to solve this issue.

I am creating a view controller that controls a views loaded from NIB file. The view has Map View with "Show user location" on true. Once user location is found I use MKReverseGeocoder to get the location data. The leak is always present when I load this view controller and MapKit finds user location. I figured out that MKReverseGeocoder isn't problem here, since I get the same leak with or without the MKReverseGeocoder.
When I load this view Instruments "leaks" report a memory leak. See the screenshot on the image:
This is how I initialize my controller:
```
AddPlaceViewController *addPlaceVC = [[AddPlaceViewController alloc] initWithNibName:@"AddPlaceViewController" bundle:[NSBundle mainBundle]];
addPlaceVC.delegate = self;
UINavigationController *navigationController = [[UINavigationController alloc] initWithRootViewController:addPlaceVC];
self.placeController = navigationController;
[self presentModalViewController:self.placeController animated:YES];
[addPlaceVC release];
[navigationController release];

Is this actually leak or what I am facing here?

3,281,685 | 1 | 3,288,440 | null | 14 | 3,684 | I'm developing an application for Google App Engine which uses BigTable for its datastore.
It's an application about writing a story collaboratively. It's a very simple hobby project that I'm working on just for fun. It's open source and you can see it here: [http://story.multifarce.com/](http://story.multifarce.com/)
The idea is that anyone can write a paragraph, which then needs to be validated by two other people. A story can also be branched at any paragraph, so that another version of the story can continue in another direction.
Imagine the following tree structure:
Every number would be a paragraph. I want to be able to select all the paragraphs in every unique story line. Basically, those unique story lines are (2, 7, 2); (2, 7, 6, 5); (2, 7, 6, 11) and (2, 5, 9, 4). Ignore that the node "2" appears twice, I just took a tree structure diagram from Wikipedia.
I also made a diagram of a proposed solution: [https://docs.google.com/drawings/edit?id=1fdUISIjGVBvIKMSCjtE4xFNZxiE08AoqvJSLQbxN6pc&hl=en](https://docs.google.com/drawings/edit?id=1fdUISIjGVBvIKMSCjtE4xFNZxiE08AoqvJSLQbxN6pc&hl=en)
How can I set up a structure is performance efficient both for writing, but most importantly for reading?

3,282,411 | 1 | 3,283,534 | null | 3 | 907 | I'm writing a simple web report with a simple layout for internal use.
The layout consists in a header on top and a content below, usually a table and a little more (very simple).
My problem is that when the table is larger than the browser's viewport, the layout messes up: the header is wide as the viewport and not as the page `body` so when I scroll right it goes off screen, an the right border of the table is stuck against the viewport right side even though I a margin for the body.
The HTML code of a clean test page is (number of `tr` elements reduced for lightness):
```

The content of `style.css` is:
```

html, body { margin: 0pt; padding: 0pt; }
body { background-color: rgb(192, 255, 192); }

```
This is how it shows in Mozilla Firefox 3.6.6 (Internet Explorer 8.0.6001.18702 has the same problem):
How can I have the header right (have the background colour stretch to the right while the text is centered in the "first" viewport", stay fixed without moving, other pretty ideas), and have the table's right border spaced from the page's border?
Thanks in advance, Andrea.

[](https://i.stack.imgur.com/o31oG.png)
The iPad HIG suggests using a bottom-aligned UIToolbar, but the appearance is incorrect. This screenshot shows Black Opaque, but none of the standard styles match Keynote.
Any advice on recreating the Keynote look would be appreciated. If you don't have Keynote on the iPad, you can see the same technique in the footer of the Bookmarks popover in Maps.

In the program there are two text boxes that ask for "row" and "col" size and then you press the button and a list box shows
```
...............................................................................................................................

2......3.......Vacant..........................................................................................................................................................
3------1----Vacant....................................................................................................................................
etc.............................................................................................................................................................
```
and when I double click one line it has to say "Reserved"
Can someone help me what to do this please?
This is my project folder so far here you can see my [failed code](http://www.mediafire.com/?o6ol8crpx7x9rno) and [this is my assignment](http://www.mediafire.com/?vfr3bvfyk673bmd)

If I try to view an Word or Excel document — by either `-loadData:MIMEType:textEncodingName:baseURL:` or by `-loadRequest:` — my app throws an exception and crashes.
If I view the document through a web server, via Mobile Safari, the Safari browser displays the following error message:
My own `UIWebView` crashes while Mobile Safari works. What am I missing in setting up my web view that is causing an exception to be thrown?

canvas url = `http://mydomain.com/fb/canvas/`
tab url = `tab.html`
i authenticated my app with my profile and added the tab to my profile. but the tab keeps loading and loading. sometimes i also get redirected to my profile page after a short tab loading time
trying to access my canvas page `http://apps.facebook.com/myapp/` works fine. also trying to access my tab page (which must be realtive to canvas) works with the apps url `http://apps.facebook.com/app/tab.html`.
does anyone know why i cannot access my tab page via the tab of my profile? the content of `tab.html`is just a little bit of "lorem ipsum", no php, no js, no body tags, nothing, just text.
looking into web-inspector, there is a file called `tab.php` which gets queried via ajax, but the content of this file is

3,294,457 | 1 | null | null | 4 | 505 | I want to be able to define everything about a form field in one place, as opposed to having some info in the DB, some in HTML, some in JavaScript, some in ASP...
Why do I have to worry about possibly changing things in four separate places (or more) when I want to change something about one field?
I.e., I don't want to:
- - - -
Since I'm a developer, I'm ideally looking for a methodology, not a tool or S/W package. (I think!)
, I'm doing this by putting all control information into SQL's extended property "Description" text area. E.g., a required phone number field would have the following SQL declaration:
`[home_phone] [varchar](15) NOT NULL`
and I put the following "controls" in the Description extended property:
`["Home Phone"][phone_text][user_edit][required][allow_na][form_field_size_equals_size][default=""][group="home_address"][rollover="enter only: numbers, dash, parenthesis, space"][explanation="enter <strong>n/a</strong> if you don't have a home phone"]`
With my current system, the following HTML is dynamically generated for the Home Phone field:
```
<div class="div-item" id="item-FORM:FIELD:TABLE_HOME:HOME_PHONE">
<div class="div-item-description" id="item_description-FORM:FIELD:TABLE_HOME:HOME_PHONE">
<span class="rollover-explanation" title="enter only: numbers, dash, parenthesis, space">
<label for="FORM:FIELD:TABLE_HOME:HOME_PHONE" id="item_label-FORM:FIELD:TABLE_HOME:HOME_PHONE">
Home Phone
</label>
</span>
</div>
<div class="div-item-stipulation" id="item_stipulation-FORM:FIELD:TABLE_HOME:HOME_PHONE">
<span class="stipulation-required" id="item_stipulation_span-FORM:FIELD:TABLE_HOME:HOME_PHONE" title="required" >
*
</span>
</div>
<div class="div-item-value" id="item_value-FORM:FIELD:TABLE_HOME:HOME_PHONE">
<div class="individual-forms">
<form class="individual-forms" id="FORM:TABLE_HOME:HOME_PHONE" name="FORM:TABLE_HOME:HOME_PHONE" action="" method="post" enctype="multipart/form-data" onsubmit="return(false);">
<div class="individual-forms-element">
<input
class=""
type="text"
id="FORM:FIELD:TABLE_HOME:HOME_PHONE" name="FORM:FIELD:TABLE_HOME:HOME_PHONE"
size="15" maxlength="15"
value=""
FORM_control="true"
FORM_control_name="Home Phone"
FORM_control_is_required="true"
FORM_control_is_phone_text="true"
>
</div>
</form>
</div>
</div>
<span class="spanExplanation">
enter <strong>n/a</strong> if you don't have a home phone
</span>
</div>
```
which looks like this (in IE 7):
Client-side JavaScript validation is controlled by the `**FORM_control**...` parameters, which on error produces explanations and field highlighting. (Unfortunately, custom parameters in HTML elements isn't exactly standards compliant.)
is that this method using the Description field has always been cumbersome to use and maintain. The Description property can only be 255 chars, so I have lots of abbreviations. As the system has expanded, the number of controls has also greatly expanded past the original dozen or so. And my code for interpreting all these controls and their abbreviations is just not pretty or efficient. as I said, custom parameters in HTML elements don't work in FireFox.
Things I'm currently controlling (and want to continue to control) include:
- - - - - - - - - - - - - - - - - -
And to be clear, I'm all for separation of logic and design elements. I do have a separate CSS file which is manually maintained (not part of the generation process).
My server environment is classic (non-.Net) ASP and SQL 2008. I'm pretty good with HTML, CSS, JavaScript, and ASP and I'm comfortable with SQL.
What I imagine that is some sort of JSON, XML, etc that is the single source used to generate everything, e.g.:
- - -
My current method that does this is dynamic (not compiled) and pretty slow, so I'm probably looking for some sort of "compiler" that generates this stuff once. And I really only have classic ASP, JavaScript or SQL as the available languages for this "compiler".
And while I think I could create this system myself, I'm hoping that other, better developers have already come up with something similar.
Assume this should scale to at least scores of fields. (FYI, my current form has way too many fields on one page, but I'm solving that issue separately.)
Thanks for any help!

I would really appreciate any help. This is freaking me out as it worked perfectly fine. has activated its "break in the last second mode". It is a hidden feature designed to drive developers mad.
uses advanced heuristic algorithm to determine how important that project is. If it is important the following code executes:
```

[popups displayAllPossiblePopups];
[build failWithError:[error someRandomIrrelevantError]];
}
```
And yes, I have rebooted my Mac. I am running XCode 3.2.2 but I don't think that matters as I haven't updated anything else because I always cancel those irritating update pop-ups. I wish there would be an "" mode which would disable all pop-up windows.
Edit:
: Thanks you've saved my life. I was literally ripping my own hair out because of that. The person who changed that and then committed the change better have an explanation for it.
