The captureStillImageAsynchronouslyFromConnection method of AVCaptureStillImageOutput seems to be quite slow with larger images (AVCaptureSessionPresetPhoto on iPhone 4S). It works perfect though for the lower presets/resolutions (including iPod touch's camera). I also tried the WWDC sample code AVCam and also got a delay from when the picture was taken to the point when I could actually display it in an UIImageView.
Is there a faster, more efficient way than making a UIImage from NSData (got from [AVCaptureStillImageOutput jpegStillImageNSDataRepresentation:imageSampleBuffer])?
I could alternatively display a HUD message that the image is being processed or set a lower quality preset, but the fact that I'm actually even experiencing a delay is annoying me.
Just to mention - I'm also cropping/resizing the image after the user snaps it and that adds a bit more to the delay, but not much.
Thanks for all the suggestions/anwsers!

It works pretty good, but I was just wondering if I could reduce the amount of connections to the database. Currently, I have some JQuery code in the page which refreshes parts of it to show the latest data. Now, I've never used JQuery before, so I did it like this:
<script>
$(document).ready(function() {
$("#blocks").load("blocks.php<? if($usePlayer){echo("?player=" . $player);} ?>");
$("#global_stats").load("globalstats.php<? if($usePlayer){echo("?player=" . $player);} ?>");
$("#top_entities").load("entities.php<? if($usePlayer){echo("?player=" . $player);} ?>");
var blockRefresh = setInterval(function() {
$("#blocks").load("blocks.php<? if($usePlayer){echo("?player=" . $player);} ?>");
}, 5000);
var globalStatsRefresh = setInterval(function() {
$("#global_stats").load("globalstats.php<? if($usePlayer){echo("?player=" . $player);} ?>");
}, 30000);
$.ajaxSetup({ cache: false });
});
</script>
The thing is, all three parts of the page I am reloading need a MySQL database connection. Currently, I am including db.php on every page, but that seems rather inefficient. What would be a good way to do this instead?
Oh, the page can be seen here: http://mc.centrility.nl/stats/ | php | jquery | mysql | database-connection | null | null | open | Reduce database connections

I have a question? having googled this I felt it would be beneficial to ask here direct, is there anyone that has a howto and tutorial on using phpquery with codeigniter. I ask because I would like to manipulate certain css attributes and swap out certain css values. I could have done this with javascript but its tough mixing php and javascript so it means finding a way to manipulate html and css to do this. Hope y'all can help in anyway.

Here's an example where this holds:
// create boxed int
IFormattable box = 42; // box.GetType() == typeof(int)
// unbox and narrow
short x1 = (short)box; // fails runtime :-)
short x2 = (short)(int)box; // OK
// unbox and make unsigned
uint y1 = (uint)box; // fails runtime :-)
uint y2 = (uint)(int)box; // OK
// unbox and widen
long z1 = (long)box; // fails runtime :-)
long z2 = (long)(int)box; // OK (cast to long could be made implicit)
As you can see from my smileys, I'm happy that these conversions will fail if I use only one cast. After all, it's probably a coding mistake to try to unbox a value type into a different value type in one operation.
(There's nothing special with the `IFormattable` interface; you could also use the `object` class if you prefer.)
However, today I realized that this is different with enums (when (and only when) the enums have the same underlying type). Here's an example:
// create boxed DayOfWeek
IFormattable box = DayOfWeek.Monday; // box.GetType() == typeof(DayOfWeek)
// unbox and convert to other
// enum type in one cast
DateTimeKind dtk = (DateTimeKind)box; // succeeds runtime :-(
Console.WriteLine(box); // writes Monday
Console.WriteLine(dtk); // writes Utc
I think this behavior is unfortunate. It should really be compulsory to say `(DateTimeKind)(DayOfWeek)box`. Reading the C# specification, I see no justification of this difference between numeric conversions and enum conversions. It feels like the type safety is lost in this situation.
**Do you think this is "unspecified behavior" that could be improved (without spec changes) in a future .NET version?** It would be a breaking change.
Also, if the supplier of either of the enum types (either `DayOfWeek` or `DateTimeKind` in my example) decides to change the underlying type of one of the enum types from `int` to something else (could be `long`, `short`, ...), then all of a sudden the above one-cast code would stop working, which seems silly.
Of course, the enums `DayOfWeek` and `DateTimeKind` are not special. These could be any enum types, including user-defined ones.

The basic scenario was the ability total up all the Quantity values for every row in a List grouped by the GroupNo field. If the sum of any of the groups was more than 10 then an error should be displayed.
I was kindly given an answer in the previous post which works perfectly. Here it is...
The model:
public class ItemDetails
{
public int SerialNo { get; set; }
public string Description { get; set; }
public int GroupNo { get; set; }
public decimal Price { get; set; }
public int Quantity { get; set; }
}
public class MyViewModel
{
[EnsureMaxGroupItems(10, ErrorMessage = "You cannot have more than 10 items in each group")]
public IList<ItemDetails> Items { get; set; }
}
and the validation attribute itself:
[AttributeUsage(AttributeTargets.Property)]
public class EnsureMaxGroupItemsAttribute : ValidationAttribute
{
public int MaxItems { get; private set; }
public EnsureMaxGroupItemsAttribute(int maxItems)
{
MaxItems = maxItems;
}
public override bool IsValid(object value)
{
var items = value as IEnumerable<ItemDetails>;
if (items == null)
{
return true;
}
return items
.GroupBy(x => x.GroupNo)
.Select(g => g.Sum(x => x.Quantity))
.All(quantity => quantity <= MaxItems);
}
}
and finally your controller actions will work with the view model:
public ActionResult ListItems()
{
var model = new MyViewModel
{
Items = ItemsRepository.GetItems()
};
return View(model);
}
[HttpPost]
public ActionResult ListItems(MyViewModel model)
{
if (!ModelState.IsValid)
{
return View(model);
}
...
}
and next the corresponding strongly typed view:
@model MyViewModel
@Html.ValidationSummary()
@using (Html.BeginForm())
{
@Html.EditorFor(x => x.Items)
<button type="submit">Go go go</button>
}
and the last bit is the corresponding editor template that will automatically be rendered for each element of the Items collection so that you don't even need to write for loops (`~/Views/Shared/EditorTemplates/ItemDetails.cshtml`):
@model ItemDetails
@Html.HiddenFor(x => x.SerialNo)
@Html.LabelFor(x => x.Description)
@Html.HiddenFor(x => x.GroupNo)
@Html.LabelFor(x => x.Price)
@Html.TextBoxFor(x => x.Quantity)
**The new problem**
As well as server-side validation I would like this to work client-side. I have written the jQuery to perform this and it works. However as well as this List level validation I will have additional property level validation. For example let's assume I also have a Required attribute on the Quantity field.
I would like it all to validate using unobtrusive MVC validation. But I cannot figure out how to unobtrusively validate the EnsureMaxGroupItemsAttribute attribute against the list as a whole.
I've implemented IClientValidatable in this way:
Public Function GetClientValidationRules(metadata As System.Web.Mvc.ModelMetadata, context As System.Web.Mvc.ControllerContext) As System.Collections.Generic.IEnumerable(Of System.Web.Mvc.ModelClientValidationRule) Implements System.Web.Mvc.IClientValidatable.GetClientValidationRules
Dim result = New List(Of ModelClientValidationRule)
Dim rule = New ModelClientValidationRule() With { _
.ErrorMessage = "You cannot have more than 10 items in each group", _
.ValidationType = "itemscheck"}
result.Add(rule)
Return result
End Function
I've created the adaptor in my JS file:
jQuery.validator.unobtrusive.adapters.addBool("itemscheck");
... and ...
jQuery.validator.addMethod("itemscheck", function (value, element, params) {
// The check has been omitted for the sake of saving space. However this method never gets called
return false;
});
Is there a way to hook this up to work unobtrusively?

I've come face to face with a rather strange mod_rewrite/Codeigniter issue and hope that someone could help me resolve it.
I'm using the following rewrite rule in my .htaccess file:
RewriteCond $1 (^profile$)
RewriteRule ^(.*)$ /user/$1 [L,NC]
What this is supposed to do is redirect all requests to http://example.com/profile to http://example.com/user/profile, but there is a problem:
I also have the rule to remove index.php from codeigniter URIs:
RewriteCond $1 !^(index\.php|images|captcha|css|robots\.txt)
RewriteRule ^(.*)$ /index.php/$1 [L,NC]
If I request /user/profile, it works just fine and displays the page. But if I request just /profile, CodeIgniter spits out a 404.
I'm using RewriteLog to debug the rewrite rules, and have confirmed that in both requests, the final internal redirect is identical:
internal redirect with /index.php/user/profile [INTERNAL REDIRECT]
When adding the [R] flag to the rewrite rule and requesting /profile, it successfully redirects to /user/profile and displays the page, but with an internal redirect it always spits out a 404.
Any help would be greatly appreciated, as this issue has had me stumped for hours.
Thank you!

**My question is pretty simple:**
Does OpenGL's glBindTexture() method require a pointer to a GLuint or does it only require a valid GLuint?
The khronos docs here says it only requires a GLuint.
http://www.khronos.org/opengles/documentation/opengles1_0/html/glBindTexture.html
**The problem is the following:**
I'm having a custom data type in v8 (new Texture(url)) that is used for initializing and loading the textures. After loading, the textures were generated via:
GLuint texture;
glGenTextures(1, &texture);
glBindTexture(GL_TEXTURE_2D, texture);
glTexImage2D(GL_TEXTURE_2D, 0, GL_RGBA, width, height, 0, GL_RGBA, GL_UNSIGNED_BYTE, (GLvoid*) image_data);
glTexParameteri(GL_TEXTURE_2D, GL_TEXTURE_MIN_FILTER, GL_NEAREST);
So this method returns the GLuint from the c++ side and attaches the casted Integer value (float due to JavaScript having nothing like typedef int/uint) to an object in the JavaScript context:
var texture = new Texture('./texture.png');
gl.bindTexture(gl.TEXTURE_2D, texture.id); // this is the casted v8::Integer value
When using the bindTexture method on the global gl (namespace) object in v8, it does the following on the native side:
v8::Handle<v8::Value> GLglBindTextureCallback(const v8::Arguments& args) {
// blabla...
int arg0 = args[0]->IntegerValue();
unsigned int arg1 = args[1]->Uint32Value();
glBindTexture((GLenum) arg0, (GLuint) arg1);
// ... blabla
}
Thanks for helping!

so, i'll would do something like

I have a simple way of making a lattice with small spheres which all have the same color, but I want the colors to alternate: to make NaCl lattice I need to have a sphere of one color surrounded by 6 spheres of other color.
So I did this:

for k in odd:

And I get spheres of one color next to speres of different color, but they are in rows:

But I need them to alternate :\ The correct placement is only in the i direction. How do I correct the others to make a simple cubic lattice? I tried fiddling with the positions of the spheres (i,j,k+-number), but that way I got bcc lattice (one green sphere in the middle, others around it).

var router = bogart.router();

var form = new formidable.IncomingForm();
var res = bogart.res();

However now I'm starting to get a pop-up everytime I click on something saying 'AN ERROR HAS OCCURED - JAVA.NULLPOINTER.EXCEPTION'.
I understand a nullpointer exception in Java is when something has been created but I haven't even typed in any code yet its just a standard mainactivity class created by the app creation wizard when you click new project.
The problems started when I ran the program and it seemed to have had an issue with 'sctivity_mainlayout.out.xml' or whatever its called.
Anyone got any ideas as to why this happening it was working before and I haven't begun to code my application.
Few details:
Eclipse using the Android ADT Plugin and Android SDK with an Android Virtual Device for testing.
Thanks guys.
P.s. I deleted the project in windows explorer and in Eclipse so got rid of it completely and any new project now is producing the same pop-up error. | java | android | xml | eclipse | null | null | open | Eclipse android configuration issue

As you can see from the log file, it looks like there is no transaction being created. With no transaction being created, there is obviously no way to roll back the updates to the database. I have been banging my head against a wall on this for 2 days now, and have not been able to get any closer to getting the desired behavior. Any help I can get on this would be greatly appreciated. | 0 |

The application has many forms with combo boxes who's items are conditionally populated. This is being handled in the old application through an Access database stored within the application and queried using the DAO object library. I was thinking Silverlight would let me mimic this functionality, but I found out that Silverlight does not allow for local database storage and manipulation (please correct me if I am wrong). I cannot go the web service route for database manipulation because this app has to work offline and Out of Browser on Mac and Windows.
So, I am looking for alternatives. It seems that I can use XML and LINQ to achieve a sort of quasi-database. My question regarding this is will it still work on Mac and Windows platforms? Any other alternatives are also welcome. | xml | silverlight | linq | null | null | null | open | Silverlight database using XML

Is it possible to rename the row indices like so?

yyy 1 1 3 2
zzz 1 1 3 2
Essentially, instead of having numeric indices, I have strings as id's, like a hash table. | r | matrix | row | hashtable | data.frame | null | open | R row indices as strings?
