Re: [android-developers] Timer in Android

I would create a remote service for the timer, and query it, since it would run independently from the activity.

I figured out the problem. I had %s in my sql, and they was getting
treated as a format specifier. When I built the sql I did put in '%%',
but I had to put in 4 '%%%%' for it to work.

This happens when I send the following HTML as a string to the
Atmosphere comet framework but that framework just seems to pass this
to GWT's ClientSerializationStreamWriter &
ServerSerializationStreamReader. Here is the string that fails:
<div style="font-family: Arial; font-size: 10pt;"><div
class="chatline" style="text-indent:-10px; margin-left:10px;"><span
class="timestamp-self" style="color:#FF0000;">(Apr 30 2012 15:11:33) </
span><span class="from-self" style="color:#FF0000;">tom: </span><span
class="message">a</span></div>
</div>

But this string works fine with same method:
<div style="font-family: Arial; font-size: 10pt;"></div>

What's going on here? Is there some known restrictions sending HTML
with GWT serialization? How to fix this?

You still haven't show us what "sql" contains... Given your three
statements I'd expect to get an error message since "sql" itself is
undefined.

Re: [android-developers] Re: Canvas performance for games

I second the OpenGL route.  It's pretty much the only thing that'll give you the performance you want.  You may also want to check:

You can indeed choose to only render parts of the screen that you consider dirty, which can also help with your performance, but likely you should be able to get the performance you want with just openGL, a texture atlas and drawing it all at once.

I'm new to Android and Java, learning by porting a game I wrote years

Games" by Mario Zechner, I'm using the technique of creating a fixed size
android.graphics.Bitmap (640x480) in RGB_565 format, rendering the game
tile by tile to its canvas with drawBitmap(bmp, srcRect, dstRect, 0),
then blitting the 640x480 bitmap to a SurfaceView's canvas, also using
drawBitmap().  AIUI drawBitmap() will scale if necessary, but I've only
tested with 1:1 scaling on an 800x480 device, leaving a gap on the side.
All the above is done in a separate thread, using a SurfaceHolder.

It's too slow, even without the debugger attached. The test device is a
ZTE Blade. The original ran at 50fps and looked nice and smooth. I'll
probably run the Android version a bit slower to compensate for
controller difficulties, but I'd like to keep the same amount of
movement per frame. I could halve the framerate and double the movement
per frame, but I think I'd struggle to reach even 20fps, and dropping
the rate further would make it unpleasantly jerky.

I've added some basic profiling and got some average times:

Game logic: < 1ms, fine, but still a lot to be implemented
Rendering the game tile by tile: 46ms, too slow
"Blit": 8ms, not too bad but would need improving to allow time for
        all the other stuff

The core of the stage that's too slow consists of rendering tiles. Each
tile is 32x32 pixels and the game world is made up of 20x15 of them.
There's one source pixmap, also RGB_565, containing all the tiles, and
the correct 32x32 portion for each tile is obtained by the srcRect.

I don't think I could significantly improve the logic of the loop that
does the tile rendering, but I could change the paradigm so that I only
render the tiles that have changed between frames. However, the draw the
whole world on each frame technique is nice and simple and used to work
even back in the days of Acorn computers with <100MHz ARMs, and I want
to progress to writing 4 way scrolling games, where the whole screen has
to be updated every frame. And even in this one I sometimes have to
update a whole load of tiles at once when there's a big explosion chain.

So I think it's just too slow to use Canvases and Bitmaps this way. Is
the answer to my problem to use OpenGL?

Re: RequestFactory and Value Proxy for Objectify Key problem

For anyone else that passes this way looking for the cause of the AssertionError: Incorrect size: 2 in AutoBeanCodexImpl$CoderCreator.getCoder()...

[Rails] Flot won't Plot

I'm playing around with FLOT with Ruby and I'm having a hard time
passing the code to javascript; I know my javascript isn't reading the
data correctly from Ruby. I need some syntax help.

Ruby Code:

o={};
o= {'label' => "A", 'data' => @example.collect{|x|
[Time.utc(x.date).to_i, x.num]}}
render :text => o.to_json


I have successfully rendered the output as such:

{"label":"A","data":[[1281225600,1.31],[1281225600,1.31],[1281225600,1.25]]}

The HTML outputs this data only.




My javascript is as follows:


var obj = jQuery.parseJSON(text);
var options = {
lines: { show: true },
points: { show: true },
xaxis: { mode: "time", timeformat: "%m/%d/%y", minTickSize: [1,
"day"]}};

var data = obj;
$.plot(placeholder,[data],options);
}


I think the jQuery.parseJSON(text); isn't working. Any suggestions will
be helpful.

[Rails] Re: parentheses vs braces

I think technically it has to do with ambiguity. It doesn't really have
anything do with it being the last argument, but rather omitting the
braces anywhere else in the argument list would cause ambiguity.
Although, that's really just semantics.

Re: [android-developers] Fitting image to a screen

One point here: the assumption I'm making is that this is for a
wallpaper.

If I did, don't you think I'd be able to say how long ago it was? ;-}
But given the source of the information---direct from one of THE
Android developers (as in, the platform itself), I think it's safe to
say that you're nuts if you don't listen to what she said.

Yeah, and I tried all of that stuff, too....and no matter what, it kept
getting stretched off-screen when you set it as wallpaper.

Wait a second...is this for a wallpaper (or lwp)? Or are you just trying
to set an ImageView to full screen? If the former, no, you can't do it.
If the latter, RTFM (http://developer.android.com/guide/index.html).
That's so simple I never even considered that that's what you were
asking. And you don't need to calculate the screen size or anything to
do that. Just the right settings (in XML and maybe also in Java) for an
ImageView.

I think of a blog post (object) as having a title, subject, body,

I'm sure there are other, simpler, ways to deal with these scenarios.

Not even systems based entirely on components/widgets carry this idea
all the way down to the model layer. Components/widgets are
view/controller layer concerns.

I would not expect many to consider this to be a "scalable" design.

I'm not aware of any. But, there has to be a better way than what you
suggest. AJAX should not in any way dictate how the model layer persists
its data. It's the job of the controller and view to collect and arrange
the data for use by the model.

Re: [android-developers] Fitting image to a screen

Your joking, my whole project is depending. I need to resize this bitmap to fit the screen size, because I want to do calculation on the picture :(

What kind of calculations are you doing?  You should be able to do that without having to have the image fit the screen size.

I hate to dissapoint you, but as I learned some time ago, you can't.  No
matter what you do, the image will always be stretched beyond the limits
of the screen.  That's just how Android does it.  And if you're about to
question that, I got this directly from Dianne Hackborn in a thread I
started over a year ago (maybe two...I'm not even sure now).

Cakephp SSN Encryption

Hi - I'm looking for information on how to encrypt data in Cakephp. My
employer had a client management system built in Microsoft Access, and
I recently took that application and put it on a web-based space built
in cake. I need to now two things:

#1 How can I encrypt social security numbers from new clients coming
into the system? I'm encrypting passwords right now, but I'm not sure
how to do social security numbers.

#2 How do I take social security numbers that are currently listed in
Microsoft Access with no encryption and put them into the MySQL
database encrypted?

Thanks for the help,

I've found that cursor._last_executed doesn't exist until a query has
been executed (it's not initialized to None)

But in django I am doing this:

from django.db import connection
cursor = connection.cursor()
cursor.execute(sql)

and it's getting the error, so that would mean that the sql isn't
getting executed for some reason. I'll have to investigate that
avenue.

Re: Google Map interface question

This won't be exactly what you're after, but I have recently implemented something quite similar. The following (1.3 code) will allow the user to drag and drop a pin to change the lat/long of that pin on the fly.

View

The first thing you'll need is to do is add a couple of json properties when you're defining each of your markers in your view, for example:

var marker = new google.maps.Marker({

...

                callbackUrl: "http://www.yoursite.com/<controller>/<action>/<id>",

                draggable: true

});

Then you'll need to add an event listener to listen for the "dragend" event of the pin:

// Add a "dragend" event listener so that we can determine the lat/long of the drop point

google.maps.event.addListener(marker, "dragend", function() {

var position = marker.getPosition();

var _data = "latitude=" + position.lat() + "&longitude=" + position.lng();

$.ajax({

type: "POST",

url: marker.callbackUrl,

data: _data,

success: function(data) {

// Do some stuff to notify the user that the lat/long has been updated

}

});

});

Controller

In your callback action within your controller, you'll need something like this:

function <action>($id = null) {

$this->autoRender = false;

if ($this->RequestHandler->isAjax()) {

Configure::write('debug', 0);

$this->layout = 'ajax';

$data['<Model>']['id'] = $id;

// Build up the data based on the posted form values

foreach($this->params['form'] as $key => $value) {

$data['<Model>'][$key] = $value;

}

// Save the data

if (!$this-><Model>->save($data)) {

$this->log($data, 'error');

$this->log($this-><Model>->validationErrors, 'error');

$this->set('message', 'There was an error updating the location for <b>' . $<model>['<Model>']['name'] . '</b>');

$this->render('/elements/flash/error', 'ajax');

} else {

$this->set('message', 'The location for <b>' . $<model>['<Model>']['name'] . '</b> has been updated');

$this->render('/elements/flash/success', 'ajax');

}

}

}

Like I said, I know this isn't exactly what you're after, but hopefully it will be of some use to you.

I hate to dissapoint you, but as I learned some time ago, you can't. No
matter what you do, the image will always be stretched beyond the limits
of the screen. That's just how Android does it. And if you're about to
question that, I got this directly from Dianne Hackborn in a thread I
started over a year ago (maybe two...I'm not even sure now).

Later,

Re: [android-developers] tracing

No, that runs fine without necessarily running it through a debugger.
You will get your output either way.

Well, then you would need some code to get the actual pixel dimensions of the screen... right now you have hardcoded values of 750.  Keep in mind that doing this will cause distortion of the image... It will look stretched either in width or height.

What exactly are you trying to accomplish?  You said "the returned image is stretched and doesn't fit the mobile screen size" but I don't see anywhere in your code where you are doing anything with the screen size of the device...  What exactly are you expecting and what exactly are you seeing?

             cursor.moveToFirst();         

             String tmppath = cursor.getString(column_index);

             

         Intent intent= new Intent(this,NasalProjectionActivity.class);

         intent.putExtra("imagePath",tmppath);

           startActivity(intent);  

 Receiving Activity,

 Thats what i have on the receiving activity.

    

     Bitmap b = BitmapFactory.decodeFile(getIntent().getStringExtra("imagePath"));

        int newHe=750;

        int newWe=750;

       

        int width=b.getWidth();

        int height = b.getHeight();

        float scaleWidth = ((float) newWe) / width;

        float scaleHeight = ((float) newHe) / height;

        Matrix matrix = new Matrix();

        matrix.postScale(scaleWidth, scaleHeight);

        Bitmap resizedBitmap = Bitmap.createBitmap(b, 0, 0, width, height, matrix, false);         

Thanks alot
