<input type="hidden" name="email[0]['type']" value="Support"/>

The problem is that when you click to edit any user from the UI grid there an AJAX that post JSON to containing the information for the user which include the 'groups' column which actually is not part of the 'users' table. So I have this:
>$data = json_decode($this->input->post('data'), true);
Which originally (when the groups weren't added yet) was transformed in this:
$data = array(
'id' => $data['id'],
'email' => $data['email'],
'firstname' => $data['firstname'],
'lastname' => $data['lastname'],
'usertype' => $data['usertype']
);
And then parsed to the model named 'mUsers' where is the update function:
>$query = $this->mUsers->update($data);
And the model since now was very simple because there was only one table:
public function update($data)
{
$this->db->where('id', $data['id']);
$query = $this->db->update('users', $data);
return true;
}
But now I have to update another table - 'users_groups' and I'm thinking about my options.Is it possible to just add to the $data array show above another record:
>'groups' => $data['groups']
And try to implement all the logic in one function(If this even possible, I couldn't find info if I can have two different active record queris in one function) or the second thing I thought of was after decoding the JSON to make something like:
$dataGroups = array(
'groups' => $data['groups'] //adding groups data to be fetched for update
);
and then parsing the data to a new function, something like:
>$q = $this->mUsers->updateGroups($dataGroups);
What would be the better approach in this case?

I want to create a somehow complex application:
It is a game level editor. You can put in tiles and other objects for a level. Then "compress" the level data into a file.
With another application, it will read the file's data and play the game.
The application is for Windows mainly. Other platforms are yet to be considered.
So I need help deciding:
If you were to do something like what I described, which programming language would you choose?
I want to decide between Ruby or Python.
I want you to help me choose depending on my following needs:
- Easy GUI platform for making the editor.
- Can show sprites, move, transform them etc.
- Can play audio.
- Can compress data, graphics and audio. The compressed file can only be read by another application I make. | 4 |

- The client informs the server about the player's movement mode (moving forward or not moving) and the player's turning mode (not turning, turning left or turning right) whenever these change.
- The server loops all players every few milliseconds and calculates the angle turned and distance moved, based on the difference in time. The same calculation is done by the client.
My current calculation for the client (same math is used in server) ==>
**Turning**
var newTimeStamp:uint = UtilLib.getTimeStamp(); //set current timeStamp
var rot:uint = Math.round((newTimeStamp - turningTimeStamp) / 1000 * 90); //speed = x degrees turning every 1 second
turningTimeStamp = newTimeStamp; //update timeStamp
if (turningMode == 1) //left
{
movementAngle = fixAngle(movementAngle - rot);
}
else if (turningMode == 2) //right
{
movementAngle = fixAngle(movementAngle + rot);
}
private function fixAngle(angle:int):uint //fixes an angle in degrees (365 -> 5, -5 -> 355, etc.)
{
if (angle > 360)
{
angle -= (Math.round(angle / 360) * 360);
}
else if (angle < 0)
{
angle += (Math.round(Math.abs(angle) / 360) + 1) * 360;
}
return angle;
}
**Movement**
var newTimeStamp:uint = UtilLib.getTimeStamp(); //set current timeStamp
var distance:uint = Math.round((newTimeStamp - movementTimeStamp) / 1000 * 300); //speed = x pixels forward every 1 second
movementTimeStamp = newTimeStamp; //update old timeStamp
var diagonalChange:Array = getDiagonalChange(movementAngle, distance); //with the current angle, howmuch is dX and dY?
x += diagonalChange[0];
y += diagonalChange[1];

{
var rAngle:Number = angle * Math.PI/180;
return [Math.round(Math.sin(rAngle) * distance), Math.round((Math.cos(rAngle) * distance) * -1)];
}
This seems to work great. In order to take lag into account, the server corrects the client's info every now and then by sending this data.
With this system very little bandwidth is used to handle movement. However, the differences between my server and the client's coordinates and angles are too big. Should I maybe extend my "algorithm", to also take into account the latency a user has?

The messages have to be large and sent very rapidly for the problem to occur. Here's basically what my code is doing (not actual code, but more-or-less what's happening):
//-- setup stuff: --
Charset charset = Charset.forName("UTF-8");
CharsetEncoder encoder = charset.newEncoder();
String msg = "A very long message (let's say 20KB)...";
//-- inside loop to handle incoming connections: --
ServerSocketChannel ssc = (ServerSocketChannel)key.channel();
SocketChannel sc = ssc.accept();
sc.configureBlocking(false);
sc.socket().setTcpNoDelay(true);
sc.socket().setSendBufferSize(1024*1024);
//-- later, actual sending of messages: --
for (int n=0; n<20; n++){
ByteBuffer bb = encoder.encode(CharBuffer.wrap(msg+'\0'));
sc.write(bb);
bb.rewind();
}
So, if the packets are long enough and sent as quickly as possible (i.e. in a loop like this with no delay), then on the other end it often comes out something like this:
[COMPLETE PACKET 1]
[COMPLETE PACKET 2]
[COMPLETE PACKET 3]
[START OF PACKET 4][SOME OR ALL OF PACKET 5]
There is data loss, and the packets start to run together, such that the start of packet 5 (in this example) arrives in the same message as the start of packet 4. It's not just truncating, its running the messages together.
I imagine that this is related to the TCP buffer or "window size", or that the server here is just providing data faster than the OS, or network adapter, or something, can handle it. But how do I check for, and prevent it from happening? If I reduce the length of message per use of sc.write(), but then increase the repetitions, I'll still run into the same problem. It seems to simply be an issue with the amount of data in a short amount of time. I don't see that sc.write() is throwing any exceptions either (I know that in my example above I'm not checking, but have in my tests).
I'd be happy if I could programmatically check if it is not ready for more data yet, and put in a delay, and wait until it is ready. I'm also not sure if "sc.socket().setSendBufferSize(1024*1024);" has any effect, or if I'd need to adjust this on the Linux side of things. Is there a way to really "flush" out a SocketChannel? As a lame workaround, I could try to explicitly force a complete send of anything that is buffered any time I'm trying to send a message of over 10KB, for example (which is not that often in my application). But I don't know of any way to force a send of the buffer (or wait until it has sent).

What is a single book you would recommend to someone interested in Smalltalk?
I've started looking into Smalltalk some weeks ago. So far I've gone through the Cincom tutorials (<a href="http://www.cincomsmalltalk.com/tutorials/version7/tutorial1/">1</a> and <a href="http://www.cincomsmalltalk.com/tutorials/version7/tutorial2/">2</a>) and I've read <a href="http://squeakbyexample.org/">Squeak by Example</a>, which I found quite good for getting the hang of the Smalltalk model, despite the poor organisation and several mistakes. Now I've started <a href="http://stephane.ducasse.free.fr/FreeBooks/Art/artAdded174186187Final.pdf">The Art and Science of Smalltalk</a>.

I'm making my first iPhone app. The app will display a word on screen and then a group of words associated with the first word in a list off to the side.
This requires me to store NSStrings in NSArrays, and the NSArrays in an NSDictionary.
I know that my Model should set the contents of my collection classes so that I can tell my View what words to display via my Controller, but I'm trying to figure out where/how to set the contents of my NSArray and NSDictionary.
I thought that I should make properties for the NSArrays and NSDictionary in my header file, and then set their contents in my implementation file under their respective "setters", but it hasn't worked so far.
Does anyone have any pointers?
Thank you!

Initially there are n white balls. Each day you are allowed to take a ball. If the ball in hand is white, replace it by red ball. If it is red in color, put that ball into bag without doing anything. The question is to find the probability to have k red balls after d days.Give the general solution
I started with making a binary tree..
initially on 1st day we have n white balls, when we pick 1 ball and apply the rule we get 1 red ball and (n-1) white balls
on second day pick 1 ball, it could be white or red. if we pick white we are left with 2red and (n-2) white balls otherwise 1 red and (n-1) white balls.
these two nodes again will each have two children each for the 3rd day.. 1 with 3 red balls and (n-3) white balls , other with 2 red balls and (n-2)white balls and so on
But this is a direct recursive formula, is there a better solution? I think it can be solved with dynamic programming, but I am unable to connect dynamic programming with probability. any idea how to do this ?
Also can someone help me with how the probability will be calculated in this question?
Last, Can someone give me a good resource to study probability based programming questions?

A question posted a year ago on this forum ([Change just the font size in SWT][1]) gave me some of the information I needed, but I've still got some unknowns I haven't figured out yet.
In particular, someone signing as [hudsonb][2] offered a helpful code fragment which I'd like to reproduce below:
FontData[] fontData = label.getFont().getFontData();
for(int i = 0; i < fontData.length; ++i)
fontData[i].setHeight(14);
final Font newFont = new Font(display, fontData);
label.setFont(newFont);
// Since you created the font, you must dispose it
label.addDisposeListener(new DisposeListener() {
public void widgetDisposed(DisposeEvent e) {
newFont.dispose(image);
}
});
Suppose I used code like this to change font sizes frequently. Aren't I creating a whole sequence of DisposeListeners, and adding them to the label's listener queue? Don't I need to remove the previous listener each time before adding a new listener? Or is there some mechanism I don't understand that makes this unnecessary?

The ranges for some of the series have no data in their cells yet; the user will write/load this data later. The idea is to have the chart ready for when they do.
**Problem**: when the loop hits such a yet empty range, I get an error 1004: Unable to set XValues property of the Series class. Why and is there a way around this?
The weird thing is that doing this manually in Chart menu --> |Source Data... works perfectly fine. Actually, if you record a macro while doing this manually, the result is as follows:
ActiveChart.SeriesCollection.NewSeries
ActiveChart.SeriesCollection(4).XValues = "=Sheet2!R4C31:R32003C31"
ActiveChart.SeriesCollection(4).Values = "=Sheet2!R4C32:R32003C32"
but then Excel gives an error when re-playing this macro!
Doing this manually is not a pleasant prospect. I guess I could stick sham data in the cells, create the series, and then delete the sham data. Do I really have to pull such a bait and switch on Excel? | excel | vba | excel-vba | charts | series | null | open | Add an empty series on an Excel chart

Scenario: Developing a java app (perhaps to run in an ESB like Mule) and you won't necessarily be able to control the time of the machine on which it will run. Can your app use an NTP server to obtain the time and schedule tasks to run based on that time?
Let's say you're using Quartz as the scheduler and perhaps joda-time for handling times (if that's useful). The time doesn't have to be super precise, just want to make sure not ahead of remote systems by much.

I have noticed after a week of searching the web that a lot of gamers buy expensive mouse equipment which improves their aim. Not a lot of us can afford such equipment. But to get down to the dirty of it. Its not necessarily the mouses their using but the software that come with their mice.
Its actually software that lets them alter their sensitivity as well as their X-Axis and Y-Axis. I have seen a tutorial on how people are downloading razor drivers and editing the software info and changing the drivers to use their mouses drivers instead.
This is a good idea but it doesn't work for all. I thought to myself why cant someone just make a simple program that alters the X-axis and Y-Axis of the mouse. To soon realize later on that no-one is bothered to do such thing. It must be possible of a company can do it.
So as a brand newbie here id like to hopefully get some help on how do to such a procedure. I understand the C# interface pretty well. But its the coding side of things i am lacking. | c# | mouse | null | null | null | 05/18/2012 17:00:05 | not a real question | C# Program to change Mouse settings?

This application will be heavily dependent on a SQL database. The primary intent of the application is to provide HTML forms for adding, managing, and removing data from this database. It will be a descent sized database (1-2 dozen tables) and there will be a good number of links between them. There may also be some reporting on the data (would like to export to Excel/CSV or similar).
So here is my question, does anyone know what solution would be best for this type of situation? If this application was developed fully in PHP/CakePHP it would take quite awhile to develop by a single person and require the input of a developer to add/remove/update the database structure/fields. However I can provide much more custom interface tailored for the needs of the application and it will be web based (accessible anywhere).

There does not seem to be a good webpage which explains the basics. For starters, what is the service called? The old name has been dropped I think, and the acronym AWS used everywhere (but isn't that being an umbrella term which includes their cloud computing and 20 other services too?).
There is a lack of clear information about the new 'signature' process. Gathering together snippets of detail from various pages I've stumbled upon, it seems that prior to August 2009 you just needed a developer account with Amazon to make requests and get XML back. Now you have to use some fancy encryption process to create an extra number in your querystring. Does this mean Amazon data is completely out of reach for the programmer who just wants a quick and simple solution?
There seems to be a tiny bit of information on RSS feeds, and you can get a feed of items that have been 'tagged' easily, but I can't tell if there is a way to search for titles using RSS too. Some websites seem to suggest this, but I think they are out of date now?

I have 2 `XtraGrid` on my Windows Application Form. Both grids have more than 200k+ lines, and 8 columns of data, and I have export to excel button. There are two ways (as I know) for exporting grid data to excel.
1- `grid.ExportToXls();` or `grid.ExportToXlsx();`
2- Using Office Interop, and `OpenXML Utilities`
If I use `grid.ExportToXls();` or `grid.ExportToXlsx();`, the process time is faster than Office Interop Codes (for arround 2k lines of data). But, this method can be used for just 1 grid. So result appears on 2 different `Excel` files. So, I'am using Office Interop to merge workbooks after process completed. Here is the problem occurs.

===
I'am using Developer Express `XtraGrid` Component to show some data. I have 2 `XtraGrid` on my Windows Application Form. Both grids have more than 200k+ lines, and 8 columns of data, and I have export to excel button. There are two ways (as I know) for exporting grid data to excel.
1- `grid.ExportToXls();` or `grid.ExportToXlsx();`
2- Using Office Interop, and `OpenXML Utilities`
If I use `grid.ExportToXls();` or `grid.ExportToXlsx();`, the process time is faster than Office Interop Codes (for arround 2k lines of data). But, this method can be used for just 1 grid. So result appears on 2 different `Excel` files. So, I'am using Office Interop to merge workbooks after process completed. Here is the problem occurs. With both these ways, I am always getting `System.OutOfMemory` Exception. (See the memory graph below)
![enter image description here][1]

I'am stuck here, because the ways I know to export excel are throwing `System.OutOfMemory` Exception. Do you have any suggestion, how can I export more than 200k - 300k+ lines of data to `Excel`? I'am using `.Net Framework 3.5` on `Visual Studio 2010`.
And you can find my Interop, and `Document.Format OpenXML Utility` codes below.

}
