With emacs (non windows), I see '$' mark at the end of the line when the terminal width is narrow. Is there a way to break the long line to the next line instead of showing the '$' mark?
## ADDED
M-x auto-fill-mode works fine for text-mode, but with org-mode, the $ mark remains with the auto-fill-mode.

4,879,961 | 1 | 4,880,152 | null | 4 | 12,776 | I have two vectors in a game. One vector is the player, one vector is an object. I also have a vector that specifies the direction the player if facing. The direction vector has no z part. It is a point that has a magnitude of 1 placed somewhere around the origin.
I want to calculate the angle between the direction the soldier is currently facing and the object, so I can correctly pan some audio (stereo only).
The diagram below describes my problem. I want to calculate the angle between the two dashed lines. One dashed line connects the player and the object, and the other is a line representing the direction the player is facing from the point the player is at.
At the moment, I am doing this (assume player, object and direction are all vectors with 3 points, x, y and z):
```
Vector3d v1 = direction;
Vector3d v2 = object - player;
v1.normalise();
v2.normalise();
float angle = acos(dotProduct(v1, v2));
```
But it seems to give me incorrect results. Any advice?
Test of code:
```
Vector3d soldier = Vector3d(1.f, 1.f, 0.f);
Vector3d object = Vector3d(1.f, -1.f, 0.f);
Vector3d dir = Vector3d(1.f, 0.f, 0.f);
Vector3d v1 = dir;
Vector3d v2 = object - soldier;
long steps = 360;
for (long step = 0; step < steps; step++) {
float rad = (float)step * (M_PI / 180.f);
v1.x = cosf(rad);
v1.y = sinf(rad);
v1.normalise();
float dx = dotProduct(v2, v1);
float dy = dotProduct(v2, soldier);
float vangle = atan2(dx, dy);
}

4,882,459 | 1 | 4,882,538 | null | 1 | 383 | Alright, I know HOW to do but It's doing something weird.
I am trying to get the correct X Y coords for a `JMenu` to appear. I've found a way but it's only a hack. All the right-clicking takes place on the `JList`, for now until I add character panel, so let's say you right-click near the top-left. You expect the Y coord to be around 40~ pixels and the Y coord to be around 100~ pixels right? Because you're clicking on the near left where the `JList` is. Wrong. The x y coords count from the top left of the `JList` when I want it to count from the top left of the WHOLE application. :S
So, what did I do? Since the Y coord is correct, I added 512 pixels to the X coord so it's always in the JList. Like so:
```
int newMouseX = 512+e.getX();
popup.show(tileOffline.this, newMouseX, e.getY()); // show item at mouse
```
However, as you can tell I will not be right-clicking in the `JList` forever.
How can I make it so I get the exact X Y coords of the mouse from the WHOLE applet?

4,883,874 | 1 | 4,884,949 | null | 3 | 5,910 | I'm using raphaelJS to draw a "radar chart" to display statistical data. For each axis it should accept values between 0 and 10.
For example, the vales of a polygon with its center point right in the center of the chart [10,10,10,10,10]. Simple...
However, it might happen that data looks like this:
```
[26, 14, 48, 18, 1],
[ 3, 14, 8, 9, 5],
[10, 6, 4, 16, 3]
```
which leads to this (displaying the polygon with its center point in the bottom left off the chart):
If I would normalize data based on its biggest value (in this case 48), all of the other center points would be too near to the center the chart, and and its informative value would be around 0.
---
same data normalized based on its biggest value:
```
[5.42, 2.92, 10, 3.75, 0.21],
[0.63, 2.92, 1.67, 1.88, 1.04],
[2.08, 1.25, 0.83, 3.34, 0.63]
```
So now all of the other center points are clustered in the center of the chart, and have lost all of their explanatory power... If there was more than 3 center points, they would most likely overlap each other.
I was thinking about a relative way to display each polygon, without losing too much relation between each polygon, if it's possible...
Any ideas how to do this, or maybe another approach how to normalize?

I can't install the WWDR Apple certificate. I downloaded but then on keychain it tells me the following:
(It's in spanish so I'm translating as good as I can)
"The "Root System" keychain cannot be modified."
"To change if a root certificate is of trust or not, open the Keychain and modify the trust settings. New root certificates must be added to the startup session of the current user, or to the keychain system if they have to be shared by all users of this computer"
How can I solve this?
Update: I actually can't install a custom certificate I made and submitted for approval (approved) I downloaded it but I can't install it! I have the same error popping up.
This is the error:

4,885,095 | 1 | 4,885,405 | null | 49 | 21,809 | The method hashCode() in class Enum is final and defined as super.hashCode(), which means it returns a number based on the address of the instance, which is a random number from programmers POV.
Defining it e.g. as `ordinal() ^ getClass().getName().hashCode()` would be deterministic across different JVMs. It would even work a bit better, since the least significant bits would "change as much as possible", e.g., for an enum containing up to 16 elements and a HashMap of size 16, there'd be for sure no collisions (sure, using an EnumMap is better, but sometimes not possible, e.g. there's no ConcurrentEnumMap). With the current definition you have no such guarantee, have you?
### Summary of the answers
Using `Object.hashCode()` compares to a nicer hashCode like the one above as follows:
- - - - - - - - - `HashSet`
I'd personally prefer the nicer hashCode, but IMHO no reason weights much, maybe except for the speed.
## UPDATE
I was curious about the speed and wrote a [benchmark](https://dl.dropboxusercontent.com/u/4971686/published/maaartin/so/EnumHashCodeBenchmark.java) with surprising [results](https://microbenchmarks.appspot.com/runs/6af10de0-e379-4aad-a354-cbc8815a466c). For a price of a single field per class you can a deterministic hash code which is nearly . Storing the hash code in each field would be even faster, although negligibly.
The explanation why the standard hash code is not much faster is that it can't be the object's address as objects gets moved by the GC.
## UPDATE 2
There are some strange things [going on](https://stackoverflow.com/q/24222991) with the `hashCode` performance in general. When I understand them, there's still the open question, why `System.identityHashCode` (reading from the object header) is way slower than accessing a normal object field.

The orange color is my attempt to add a outline around the white shape. As you can see it's not so uniform. On some edges the orange doesn't show at all.
Evidently using...
```

... to draw a slightly larger orange shape before I drew the white shape wasn't the way to go.
I just have a nagging feeling I'm missing a more simple way to do this.
Note that the white part is going to be mapped with a texture which has areas of transparency, so the orange part needs to be the white shapes too, not just surrounding them.
Also, I'm using a parallel projection matrix, that's why glScalef's z is set to 0.0 - reminds me there is no perspective scaling.
Any ideas? Thanks!

4,887,456 | 1 | 4,888,128 | null | 10 | 14,623 | In the application that I'm working on right now, I need to periodically check eligibility of tens of thousands of objects for some kind of a service. The decision diagram itself is in the following form, just way larger: 
In each of the end nodes (circles), I need to run an action (change an object's field, log information etc). I tried using Drool Expert framework, but in that case I'd need to write a long rule for every path in the diagram leading to an end node. Drools Flow doesn't seem to be built for such a use case either - I take an object and then, depending on the decisions along the way, I end up in one of the end nodes; and then again for another object. Or is it? Could you give me some examples/links to such solutions?
Drools Flow calls might look like this:
```
// load up the knowledge base
KnowledgeBase kbase = readKnowledgeBase();
StatefulKnowledgeSession ksession = kbase.newStatefulKnowledgeSession();
Map<String, Object> params = new HashMap<String, Object>();
for(int i = 0; i < 10000; i++) {
Application app = somehowGetAppById(i);
// insert app into working memory
FactHandle appHandle = ksession.insert(app);
// app variable for action nodes
params.put("app", app);
// start a new process instance
ProcessInstance instance = ksession.startProcess("com.sample.ruleflow", params);
while(true) {
if(instance.getState() == instance.STATE_COMPLETED) {
break;
}
}
// remove object from working memory
ksession.retract(appHandle);
}
```
That is: I'd take an Application object, start a new process for it, when the process is finished (the final, action node would modify the application somehow), I'd remove the object from working memory and repeat the process for a new App object. What do you think about this solution?
I've ended up using Drools Flow and it has been working quite fine. My decision process isn't as straightforward as Drools Expert asks for and depending on where in the decision tree the process is it needs to load lists of objects from the database, transform them, make decisions, log everything etc. I use a Process object that is passed to the process as a parameter and stores all my global variables (for the process) and some convenience methods that are repeated at different points in the tree (as writing Java code in the `Script Task` nodes isn't very convenient itself). I also ended up using Java to make decisions (and not `mvel` or rules) - it's faster and I'd say easier to control. All objects that I work with are passed as parameters and used as normal Java variables in the code.

Units have abilities (Players possibly can as well)
The big one that I'm having trouble figuring out is Unit's Abilities. They should be able to affect anything in the game, healing/damaging a player/unit, reposition things on the board, possibly even the game itself (so far there isn't a need, but it could come up).
How can I have abilities that can affect anything without them having a reference to everything? I realize each ability can and should have references to only what it needs, but a unit class has abilities built in to them, so if a unit's ability affects the board, it will need to get a reference to the board from the unit somehow?
I'm trying to keep the design as flexible as possible, because the rules aren't set in stone yet (we're creating a game, and still pretty early on, so it's try something, see how it feels, change the rules until the game feels right)
Even whether there's a board/map at all is still up in the air, so the units should be decoupled from that, which they currently are. There is no global state or any "god object" (yet), and I'd like to keep it that way.
Specifically it's in Python, webapp, so while the question itself is language agnostic, any specifics based on a dynamic language with first class functions are certainly welcome.

4,887,792 | 1 | 4,888,345 | null | 0 | 1,126 | I'm using [Ocilib](http://orclib.sourceforge.net/) to perform a bulk insert on a Oracle database but I'm having some trouble while filling a string buffer.
The documentation says:
> For string/RAW arrays, the input array
MUST BE a contiguous block of data and
not an array of pointers. So to bind
an array of 10 elements for a
varchar2(30) column, binded variable
must be a like array[10][31]
And a sample proceeds to fill a buffer like this:
```
...
char tab_str[1000][21];
...
OCI_BindArrayOfStrings(st, ":s", (char*) tab_str, 20, 0);
...
for(i=0;i<1000;i++)
{
sprintf(tab_str[i],"Name %d",i+1);
}
...
```
I'm trying to fill the string buffer while looping through a std::vector of MyClass. MyClass has a std::string member.
I'm trying to use the std::string::copy method to copy over the string contents to the buffer. But I don't know exactly how to index the buffer to do it.
```
...
OCI_BindArrayOfStrings(st, ":f2", NULL, VCHAR_SIZE, 0);
char** vc_buffer = (char**)OCI_BindGetData(OCI_GetBind(st, 2));
...
int i = 0;
for(vector<MyClass>::const_iterator it = myVec.begin(); it != myVec.end(); ++it)
{
/* 1st try */ it->m_string.copy((vc_buffer + (i * VCHAR_SIZE)), VCHAR_SIZE);
/* 2nd try */ it->m_string.copy(vc_buffer[i], VCHAR_SIZE);
++i;
...
}
...
```
The first way gives me buggy data in the database. The second makes me hit a null pointer.
What I'm doing wrong?
:
The second approach, along the approach proposed by Alessandro Vergani below, results in null strings inserted. The first approach gives this (somewhat bizarre) result:
The gvim window shows what it's supposed to look like, the apex screen shows what ends up in the database.

I've extended `UITableView` so that double-tapping a cell enters text edit mode, at which stage the text field is added as a subview to the tapped `UITableViewCell` and becomes the first responder. The cell textLabel is purposefully hidden at this point.
My issue is: I set the and for my `UITableViewCell` and the `UITextField`, yet the two do not exactly overlap. I have produced an image illustrating this behaviour: the left side shows on top the `UITableViewCell` textLabel, below this is the `UITextField` overlaid with cell textLabel hidden, and on the right are both made visible.
I'm not keen on "fudge factor" value fixes, so can anyone tell me what's missing?

It could be a basic mapping mistake, as it's my first take on NHibernate.

I have now tried all different mappings below (1-6). Without cascade-convention, I get exception on all alternatives. Am I ? I thought it should not be required.
---
Findings to above exceptions:
1) Store is aggregate root ( No Inverse set). Since no cascade: I need to handle added children manually on saving aggregate. (OK)
2) Employee is aggregate root (Inverse set). Still, since no cascade: I need to handle added Employee manually, simply because the stores collection contain both persistent and transient entities. So the clue of 1 and 2 is simply that cascade = none. Inverse is irrelevant. (OK)
3) Store is aggregate root (No inverse set). Cascade=all, and it works in both directions, not only from the aggregate root? So we can not delete the child without first removing it's reference to the parent. (Maybe OK).
4) Same reason as 3. Inverse makes no difference on the cascade. (Maybe OK)
5) Same reason as 3.
6) Same as 1.
If this is the conclusion. Then it means we are forced to remove the reference between bidirectional entities before delete of child. No matter the setting of Inverse.
So: ?
---
(breathe..) Even setting the It still gives :
deleted object would be re-saved by cascade (remove deleted object from associations)[FNHib_Test.Entities.Employee#1]
This was with mapping;
```
public static void Delete(Employee employee)
{
using (ISession session = FNH_Manager.OpenSession())
{
using (ITransaction transaction = session.BeginTransaction())
{
employee.Store = null;
if (employee.Id != 0)
{
// var emp = session.Get(typeof(Employee), employee.Id);
Employee emp = session.Get<Employee>( employee.Id);
if (emp != null)
{
emp.Store = null;
session.Delete(emp);
transaction.Commit();
}
}
}
}
}
```

Followup:
Thank you Andreas, for what is a simple and correct answer to my question. As a Delphi 4 programmer converted to Delphi 2009, I was not familiar enough with the VCL additions of Delphi 5 to 7, so the TActionManager, TActionToolbar and their workings were not in my Delphi vocabulary. And this is based on Delphi's ability to use a style that is akin to a Microsoft O/S's theme.
However, with your answer, and a bit of research using it, I confirm that I do not want to do this in this manner. An illuminating Embarcadero thread re: Popup menus: ["Checked" items with icon no longer shown as sunken?](https://forums.embarcadero.com/thread.jspa?messageID=310325) with Peter Below contributing his expertise, made me realize that I don't want to change to the XP theme at all, since that will do baaaaad things to Vista and Windows 7 users, taking them back to the Bronze Age.
The true culprit here is that there are certain things that the O/S themes want you to respect. Delphi tries to follow the rules. I can go back to XP, the XP style/theme, and the XP Color Map. In this mode, checked items will be hilighted. And this is really all I wanted - to highlight the checked items. I used Office 2003 as an example, because it was the sort of hilighting I wanted. But I really didn't want to entirely change themes and force an entire new look on my program. It would especially make things look unnatural for Vista and Windows 7 users.
What would be ideal is if I could have another set of Images that would apply when the object is Checked ... but there is not a "CheckedImages" property. Or a way of programmatically or automatically modifying the image if it is checked (e.g. like disabled images get a grayscale version of their enabled image).
I still wouldn't mind hearing from anyone if there are any ways to implement this or something else that might work equally well, without changing the entire look of my program.

4,890,900 | 1 | 4,891,271 | null | 3 | 6,591 | I have a basic UITableView that I want to enable the style check marks while having no selection style. I have the following snippet:

{
return UITableViewCellEditingStyleMultiSelect;

- (UITableViewCell *)tableView:(UITableView *)tableView

4,892,868 | 1 | 4,893,154 | null | 1 | 699 | This is something I've never been able to figure out.
You've got a button offscreen you want to animate in. We'll call it 'btn.'
You've got a hit area that serves as the proximity sensor to trigger btn's animation. We'll call it 'hitZone' (as to not cause confusion with the hitArea property of display objects).
Both btn and hitZone are MovieClips. The listeners go something like this.
```
import com.greensock.*;
import com.greensock.easing.*;
import flash.events.MouseEvent;
var endPoint:Number = 31;
hitZone.addEventListener(MouseEvent.ROLL_OVER, onHitZoneOver);
hitZone.addEventListener(MouseEvent.ROLL_OUT, onHitZoneOut);
hitZone.addEventListener(MouseEvent.CLICK, onHitZoneClick);
btn.addEventListener(MouseEvent.ROLL_OVER, onBtnOver);
btn.addEventListener(MouseEvent.ROLL_OUT, onBtnOut);
btn.addEventListener(MouseEvent.CLICK, onBtnClick);
btn.mouseChildren = false;
function onHitZoneOver(e:MouseEvent):void
{
TweenLite.to(btn, 0.75, {x:endPoint, ease:Expo.easeOut});
trace("over hitZone");
}
function onHitZoneOut(e:MouseEvent):void
{
TweenLite.to(btn, 0.75, {x:-1, ease:Expo.easeOut});
trace("out hitZone");
}
function onBtnOver(e:MouseEvent):void
{
hitZone.mouseEnabled = false;
hitZone.removeEventListener(MouseEvent.ROLL_OVER, onHitZoneOver);
hitZone.removeEventListener(MouseEvent.ROLL_OUT, onHitZoneOut);
trace("over BTN");
// This line is the only thing keeping the btn animation from being fired continuously
// causing jumpiness. However, calling this allows the animation to be interrupted
// at any point.
TweenLite.killTweensOf(btn);
}
function onBtnOut(e:MouseEvent):void
{
hitZone.mouseEnabled = true;
hitZone.addEventListener(MouseEvent.ROLL_OVER, onHitZoneOver);
hitZone.addEventListener(MouseEvent.ROLL_OUT, onHitZoneOut);
trace("out BTN");
}
function onBtnClick(e:MouseEvent):void
{
trace("click BTN");
}
function onHitZoneClick(e:MouseEvent):void
{
trace("click hitZone");
}
```
The issue is when your mouse is over both the hitZone btn. The button continuously jumps unless you call TweenLite.killAllTweensOf(). This fixes the jumpiness, but it introduces a new problem. Now, it's very easy to interrupt the animation of the btn at any point, stopping it before it's totally visible on the stage.
I've seen [similar](http://www.kirupa.com/forum/showthread.php?t=350932) posts, but even they suffer from the same issue. Perhaps it's a problem with how Flash detects edges, because I've never once seen a workaround for this.

Guys I am new to data structures.Most of the time in books and references i see this structure for a binary tree
```
struct btree {
int data;
struct btree *left;
struct btree *right;
};
```
But in above image it would be like
```
struct btree
{
int data;
struct btree *left;
struct btree *right;
struct btree *parent;
};
```
So my question is that is it dependent on programmer to choose the structure of a node of a tree (for e.g also including a pointer to the parent )or we can have only two pointers one to the left child and other to the right child.

How do I reproduce the two buttons at the bottom of the Twitter app in this screenshot (Update and Cancel)? You can see a similar design pattern in the official Facebook app too when creating a Facebook message. Are they created with 9 patch images or is it something easier than that (setting a background color and somehow keeping border/state press color changes to orange).
This would be really simple if Twitter had open sourced their official Android app like they said they would (but never did).

4,895,465 | 1 | 4,913,615 | null | 53 | 58,413 | I'm working with the Code First feature of Entity Framework and I'm trying to figure out how I can specify the column data types that should be created when the database is auto-generated.
I have a simple model:
```
public class Article
{
public int ArticleID { get; set; }
public string Title { get; set; }
public string Author { get; set; }
public string Summary { get; set; }
public string SummaryHtml { get; set; }
public string Body { get; set; }
public string BodyHtml { get; set; }
public string Slug { get; set; }
public DateTime Published { get; set; }
public DateTime Updated { get; set; }
public virtual ICollection<Comment> Comments { get; set; }
}
```
When I run my application, a SQL CE 4.0 database is automatically created with the following schema:
So far, so good! However, the data I will be inserting into the `Body` and `BodyHtml` properties is routinely larger than the maximum allowed length for the `NVarChar` column type, so I want EF to generate `Text` columns for these properties.
However, I cannot seem to find a way to do this! After quite a bit of Googling and reading, I tried to specify the column type using `DataAnnotations`, from information found in [this answer](https://stackoverflow.com/questions/4829776/generate-money-type-fields-using-code-first-ef-ctp5/4833477#4833477):
```
using System.ComponentModel.DataAnnotations;
...
[Column(TypeName = "Text")]
public string Body { get; set; }
```
This throws the following exception (when the database is deleted and the app is re-run):
```
Schema specified is not valid. Errors: (12,6) : error 0040: The Type text is not qualified with a namespace or alias. Only PrimitiveTypes can be used without qualification.
```
But I have no idea what namespace or alias I should be specifying, and I couldn't find anything that would tell me.
I also tried changing the annotation as per [this reference](http://msdn.microsoft.com/en-us/library/system.data.linq.mapping.columnattribute.dbtype.aspx):
```
using System.Data.Linq.Mapping;
...
[Column(DbType = "Text")]
public string Body { get; set; }
```
In this case a database created, but the `Body` column is still an `NVarChar(4000)`, so it seems that annotation is ignored.
Can anyone help? This seems like it should be a fairly common requirement, yet my searching has been fruitless!

and I want to transform it into rules in Drools Expert. The use of `insertLogical` has been [proposed](https://stackoverflow.com/questions/4887456/decision-trees-and-rule-engines). Drools documentation says [this](http://downloads.jboss.com/drools/docs/5.1.1.34858.FINAL/drools-expert/html_single/index.html#d0e5121) about `insertLogical`:
> `insertLogical(new Something())`; is
similar to insert, but the object will
be automatically retracted when there
are no more facts to support the truth
of the currently firing rule.
The fact that these objects are retracted is useful (as I'll have tens of thousands of objects in memory and each will create a bunch of these). There's also a method `retract(object)`, which removes an object from working memory. When I get to an end node and remove (`retract`) the base object that would get there (following the decision tree), does it also remove all these objects created with `insertLogical` during the traversal?

If so, what is the best way to "Create project from existing sample" modifying anything in the original sample project files?
(I am assuming project duplication is involved, but step-by-step instructions would be very helpful for future Android-newbies)
The following is a snapshot of the options available, to further clarify my question:

4,898,752 | 1 | 5,816,970 | null | 4 | 3,927 | I am about to wrap up the implementation for my first ExtJS based application. But I am facing a weird issue at this point.
I am using ASP.net at the server and then ExtJS at the client. I noticed that, If I run this project from Visual Studio Debugger then it works nice, and in that case my browser URL was set to
[http://localhost/MyApp/Home.aspx](http://localhost/MyApp/Home.aspx)
But As soon as I open a new browser and hit
[http://MyWorkStationName/MyApp/Home.aspx](http://MyWorkStationName/MyApp/Home.aspx)
it behaves slightly different.
For instance, some Button Shapes are not rendered properly.
Can any body give me a clue how can I debug this issue. basically how the style can be influenced by the machine name vs localhost in URL ?
Thanks in advance!
