How can I convert latitude and longitude into magnetic variation for an IOS app (Objective C). I am looking for a simple solution I can incorporate in an app.
I willing to trade off precision and handling all possible cases for simplicity.
Simplest would be to have a stored table and interpolate your current position. I don't think you'll find a simple formula, but it doesn't change quickly with position.

I'm looking for some guidance here. I primarily am a frontend developer. What I am trying to figure out is how an algorithm can be implemented to count kernels on an ear of corn.
From my initial research it seems there are a couple of different directions to go. Main ones I have seen are a SIRF type of implementation and others call for conversion to the HSV color space or LAB color space in order to then to normalizations and then counting.
For reference usually the corn that will be counted is "dent" corn. Here is an example:
This will be implemented in VB.net, but I can always translate the algorithm if needed.
Thank you for your help!

i have a dbgeography column in sql server which stores latitude and longitude information. I want to extract latitude or longitude information using sql query but i couldn't find a way to do so. How could it be done?
No C# code.
Does something like this work?
select Location.Lat, Location.Long from GeographyTable

So, I am currently making a 1942-style game. How can/should I set up the path for my enemies? I know I could do it with CGPathRef but is there an easier way to do it? It seems pretty out of place for more complex paths like for example these 2 I'd like to implement:

(Sorry I can't directly post pictures, I need at least 10 reputation)
Or at least, I haven't found any documentation explaining how to create more complex shapes with CGPaths.
So what are your recommendations?

I'd love to know/see some example code from the lowest level. By this I mean the code that for example, sets the voltage to the speakers, or something equivalent. I can't imagine how this would look/work.
How could a piece of code possibly set/change a physical quantity? I'm not looking for some driver code, but the actual code that makes hardware 'work', or does it work in a different way?

I am trying to create a simple scatter plot with PlotSymbols for when I hit a point of data. I have all of that implemented, but the line and the symbols are all one color that blends in making it hard to see the data. I know I could make the symbols bigger, but I am hoping to try and avoid that.
From the few screen shots that I saw in the examples I saw the ability to do this, but only for the ellipse symbol. Is there any way to do this for other symbols as I am currently using the rectangle.
Every plot symbol has a lineStyle and a fill. You can mix and match to get whatever look you want.
