My question: Is there a function to read out y-values from a chart by passing an x-value as a parameter?
I have a line chart using a TimeSeries with several custom dates (for example 07/24/12 and 07/29/12). Now I want to pass another date (for example 07/25/12) and get the corresponding y-value - even though it is not stored in the TimeSeries.
I just wanted to ask, if there is a simple way like a single function to achieve this aim, otherwise I'll think about a more complicated solution on my own. In my above example, of course, it sounds quite easy to calculate the demanded y-value, but in practice it is going to be more difficult I guess.
Thank you. | android | time-series | achartengine | linechart | null | null | open | AChartEngine - read y values by x

Please read on before downvoting. :)
That's because a collegue of mine was asked this question in a job interview, and was "unable to answer properly"... to speak with his interwiewer's words.
And when he told me what he said to his interviewer I got really surprised, since it was more or less what I would have answered myself - in a concise form, the first paragraph of [this][1] article.
That seems not to be enough, since the interviewer asked for "more precise and less general definition".
Is there really a more precise definition for J2EE/JEE?
Or did my colleague just find the fussiest-interviewer-ever? :)

The plan is to login to a web application and then use a a single sign on scheme such as oauth or CAS to automatically login to a client application.
The client application does not verify the credentials itself, but uses them via ODBC to connect to the Postgres database server. Unlike web applications we cannot use a single databaes user here, but need individual database accounts for security reasons.
In theory Postgres does support PAM and PAM supports both CAS and oauth. But I was not able to find any documentation on that. Especially the part of how to specify the token in ODBC is unclear to me. | postgresql | oauth | odbc | single-sign-on | cas | null | open | How to use single sign on with ODBC?

I have an android tablet(HTC Flyer). One of my activities is to read newspapers online. I read several Sinhalese newspapers on my pc. I found out that these sites do not work in Android browser. My guess is the font is not supported. I tried Opera and Firefox as well, to no avail.
How can I resolve this problem. What are the options I can take. Is there a way to install a font in Android? Do I have to develop a browser? I'm an android developer but I'm not experienced in browser technology.

The software its a Network one, and with medium coupling with the GUI.
But the GUI is one of the most important part of my software.
Now i what to approach another markets, MAC/WIN/Linux are essential, but IOS, Meego and Android are desirable.
I think in 4 Options to convert:
1. Do all with Qt, HUGE work ,no IOs or Android support.
2. Split the "CORE" and rewrite it with STD/Boost and reuse the Windows GUI, Do Another Gui in Qt and other 2 for IOS and Android. HUGE work, the most elegant option but with huge workload in creating 3 GUIs.
3. Convert to C#. Support Linux/Mac/Ios/Android with Mono. Easy to DO, but in the hand of a lot of propriety tech.NO guaranty what will work in future. No native feeling.
4. Pack with Wine. Forget about Android/IOS
So i´m with a lot of doubts, i have fear of choosing one Tech and in future yet Another platform appear. The world was so much easer with only Windows to support.
Then i ask stackoverflow, what the best choice ? Another suggestion ?

I think in 4 Options to convert:
1. Do all with Qt, HUGE work ,no IOs or Android support.
2. Split the "CORE" and rewrite it with STD/Boost and reuse the Windows GUI, Do Another Gui in Qt and other 2 for IOS and Android. HUGE work, the most elegant option but with huge workload in creating 3 GUIs.
3. Convert to C#. Support Linux/Mac/Ios/Android with Mono. Easy to DO, but in the hand of a lot of propriety tech.NO guaranty what will work in future. No native feeling.
4. Pack with Wine. Forget about Android/IOS
So i´m with a lot of doubts, i have fear of choosing one Tech and in future yet Another platform appear. The world was so much easer with only Windows to support.
Then i ask stackoverflow, what the best choice ? Another suggestion ?

We have decided to localize it into other languages, but first we wanted to look into how other companies are doing it in order to determine what the best practices would be.
When we looked at how Apple localizes their apps we found something which we think is very strange. The App Store and iTunes apps determine their language based on the location of the user. For example, a user in Germany will get the entire apps in German even if the rest of the phone is configured to run in English.
Of course the app content will differ between different countries, for example not all apps are available in every country and so on. But we are puzzled on why the rest of the app such as navigation buttons and labels are localized this way.
An obvious scenario when this breaks would be an English speaking American moving to Germany. It is possible that he or she don't want to learn German and therefore keep using the apps in English.
We fail to see why this would be a good way to localize an app but since Apple is doing it we assume that there has to be a good reason for it.

But if the result of `(b - a)` is exactly zero, I expect that something platform dependant will happen due to divide by zero. I could change the `if` statement to:
if ((!((b-a) == 0.0)) && ((result = c/(b-a)) > 0) && (result < small_number)) {
but I don't know if `(b-a) == 0.0` will always detect equality with zero. I have seen there are multiple representations for exact zero in floating point? How can you test for them all without doing some epsilon check, which I don't need (a small epsilon will be ignored in my algorithm)?

Does anybody know how I can solve this on a correct way?
Thank you

In game class when i use setContentView(puzzleview) then it works correct that is it change views(update) when the user play with sudoku. But when use setContentView(r.id.game) in game class, it cannot update the views, when user select the value it doesnt update it in xml. Kindly go through it and give me the solution. | android | xml | view | null | null | 01/30/2012 15:25:27 | too localized | Error when refreshing xml

and the game.xml in game class is

In game class when i use setContentView(puzzleview) then it works correct that is it change views(update) when the user play with sudoku. But when use setContentView(r.id.game) in game class, it cannot update the views, when user select the value it doesnt update it in xml. Kindly go through it and give me the solution. | 3 |

My understanding of how it should work is that when you click the links at the top, it removes whatever is currently displayed, using removeChild, and adds the new page's content using addChild.
It works fine when going from the initial page to one of the links. But whenever I go from a page that is not the home page to another page I get:

| actionscript-3 | flash | removechild | addchild | null | null | open | Flash CS6 ActionScript 3 Error #2025
===
I'm working on a webpage for a class and am trying to work the navigation using ActionScript 3. My understanding of how it should work is that when you click the links at the top, it removes whatever is currently displayed, using removeChild, and adds the new page's content using addChild.
It works fine when going from the initial page to one of the links. But whenever I go from a page that is not the home page to another page I get:
> ArgumentError: Error #2025: The supplied DisplayObject must be a child
> of the caller. at flash.display::DisplayObjectContainer/removeChild()

@LazyCollection(LazyCollectionOption.FALSE)
@CollectionOfElements
@Column()
private List<String> permissions = Collections.emptyList();
It produced a SQL table with an entry like the following:
![User permissions before H4 upgrade][1]
We recently upgraded to Hibernate 4, and as the `@CollectionOfElements` annotation has gone from deprecated to completely removed, we figured this was a good time to move over to `@ElementCollection`, like so:
@LazyCollection(LazyCollectionOption.FALSE)
@ElementCollection // << CHANGED
@Column()
private List<String> permissions = Collections.emptyList();
Upon launching, however, we were unable to log in with our *administrative* account. Curious, we examined the database using H2's JAR, and found the table had been altered:
![User permissions after][2]
**My questions:**
1. Is there a comprehensive list of the DDL/schema changes from the old `@CollectionOfElements` to the new `@ElementCollection`?
2. Is there a recommended practice, or additional annotation I can provide to these properties, that will ensure backwards compatibility? (Can I specify a specific name-mapping scheme or column name?)
3. Finally, I assume all `Collection` types will be affected by this change - `Sets`, `Maps`, etc. I just want to ensure that we don't leave any data behind, or stone unturned, during our upgrade.

Here's a simple function:
function runjQueryTest(){

$.get( url, function(){});
}
On the server (PHP) I record the value of the request uri `($_SERVER["REQUEST_URI"])` and I see a difference between what FF/Chrome send up versus what IE sends up.
Chrome and FireFox cause the value of `($_SERVER["REQUEST_URI"])` to be

but requests from IE 8 show the value of `($_SERVER["REQUEST_URI"])` to be

Abstract Method:

- Pros:
Forces sub-class to think about this value and choose what they want it to be.
- Cons:
No default value, so even if most of the sub-classes just want to use the same value they still have to implement the method. (The method can be made non-abstract and return the default value, but then you lose the advantage of forcing sub-classes to think about the value)
Protected Variable:
protected int value;

- Pros:
Can define a default value and sub-classes can just ignore it if they don't care.

glGenBuffers(1, vbo_id);
glBindBuffer(GL_ARRAY_BUFFER, vbo_id)

glBufferData(GL_ARRAY_BUFFER, sizeof(data), data, GL_DYNAMIC_DRAW)
B) update vertices:
draw():
# calc new data and update offset
data = calc new values sin([n+dx, n+2*dx])
# update offset 'n'
n = n+2*dx
# upload data
glBindBuffer(GL_ARRAY_BUFFER, vbo_id)
glBufferSubData(GL_ARRAY_BUFFER, offset, sizeof(data), data)
# translate scene so it looks like sine wave has moved
glTranslatef(-local_shift, 0.0, 0.0)
# draw all points from offset
glVertexPointer(2, GL_FLOAT, 0, offset)
glDrawArrays(GL_LINE_STRIP, 0, points_per_vbo)
This works just fine, however if I have let's say 20 of those sine waves that span the entire screen, then things slow down considerably.
**Therefore my questions:**
1) should I use glMapBuffer to bind the buffer on the GPU and fill the data directly (instead of using glBufferSubData)? Or will this make no difference performance wise?
2) should I use a shader for moving objects (here line strip) instead of calling glTranslatef? If so, how would such a shader look like?
3) what happens if the window get's resized? how do I keep aspect ratio and scale vertices accordingly? glViewport() only helps scaling in y direction, not in x direction. If the window is rescaled in x-direction, then in my current implementation I would have to recalculate the position of the entire line strip and upload it to the GPU. I guess this could be done with a shader instead too?
4) I noticed that when I use `glTranslatef` with a non integral value, the screen starts to flicker if the line strip consists of thousands of points. This is most probably because the fine resolution that I use to calculate the line strip does not match the pixel resolution of the screen and therefore sometimes some points appear in front and sometimes behind other points (this is particularly annoying when you don't render a sine wave but some 'random' data). How can I prevent this from happening (besides the obvious solution of translating by a integer multiple of 1 pixel)? If a window get re-sized from let's say originally 800x800 pixels to 100x100 pixels and I still want to visualize a line strip of 20 seconds, then shifting in x direction must work flicker free somehow with sub pixel precision, right?
[1]: http://i.stack.imgur.com/yN3Ik.gif | opengl | null | null | null | null | null | open | what is the most efficient way of moving multiple objects in space? should I use glTranslatef or a shader?
===
I'm trying to get the hang of moving objects most efficiently in opengl and therefore I'm writing an application where multiple sine waves are traveling with a constant speed from right to left. To illustrate what I mean, see this image:
![traveling sine wave][1]
Because I want to work with many objects, I decided to use vertex buffer objects in order to minimize the amount of `gl*` calls. My current code looks something like this:
A) setup initial vertices:
# calculate sin(x) in range [0, n]
data = sin(x)
# create & bind buffer
vbo_id = GLuint()
glGenBuffers(1, vbo_id);
glBindBuffer(GL_ARRAY_BUFFER, vbo_id)
# allocate memory & transfer data to GPU
glBufferData(GL_ARRAY_BUFFER, sizeof(data), data, GL_DYNAMIC_DRAW)
B) update vertices:
draw():
# calc new data and update offset
data = calc new values sin([n+dx, n+2*dx])
# update offset 'n'
n = n+2*dx
# upload data
glBindBuffer(GL_ARRAY_BUFFER, vbo_id)
glBufferSubData(GL_ARRAY_BUFFER, offset, sizeof(data), data)
# translate scene so it looks like sine wave has moved
glTranslatef(-local_shift, 0.0, 0.0)
# draw all points from offset
glVertexPointer(2, GL_FLOAT, 0, offset)
glDrawArrays(GL_LINE_STRIP, 0, points_per_vbo)
This works just fine, however if I have let's say 20 of those sine waves that span the entire screen, then things slow down considerably.

1) is it against my MSDN license agreement to release a website using the software?
2) how do i protect my "idea"? is it a bad idea to find random people you don't know to test out your site? can you make them digitally sign some sort of NDA?
3) i'm using some open source code - any proper way to release open source code to live production?
4) how much traffic can a place like discountasp.net handle anyway? can hosting sites generally handle large volume of traffic?
any comments/suggestions regarding the proper/safe way to release a public website would be appreciated. i've been working on this for a while and never actually sat down to think about the right way to move from a personal side project to a live production website. | releasing | new-operator | website | null | null | 04/27/2010 14:54:12 | off topic | what's the correct way to release a new website?

I am new to java coding and jNetpcap lib was very useful in doing most of my task.
I am able to get certain fields from http header like content_length,response code etc.However I couldn't figure out why RequestURL, RequestMethod,getMessageType() fields were showing up as NULL when they are actually not in original file. I have used tcp port numbers to filter Request/Response http packets. But I do need the RequestURL field. Please let me know where I am going wrong
help would be greatly appreciated
I use this:
final String req_url = http.fieldValue(Http.Request.RequestUrl);
