I am looking for a charting library and zeroed in on JQplot the library looks impressive.
however i didnt got much info about(reviews) about Google chart API, has any one compared the pro's and cons of Jqplot and Google charts api ? Do i need to use GWT for using Google Charts API?
Google api chart generates swf file (i.e. flash file) and jqplot draws chart on canvas(html5 element)
Both charting tools are easy to use
Most of the facilities (e.g zoom, mouseover effect, labels on chart, multiple scales on chart etc ) that are provided in google chart are also provided in jqplot
jqplot provides facility that when u resize your browser window jqplot automatically resize your chart but this is not in google chart

Is there any way to find out if I am within village/city or out the village/city using iOS SDK (geocoder information) or Overpass API for OSM?
I know there are commercially APIs providing this feature, but I am wondering if it exists any API or service for free? I am working on pseudo-navigation app and I need this info about my current location.
Edit: For now I am using geocoding - placemark info about location - if thouroughfare is null or some number (street or road No.) - I am out the town. If there is some 'string' - it is street name and I am in the city. But this approach is very inaccurate. I am also considering using Overpass API for Open Street Maps and I am wondering if OSM provides such information. Thanks for any sugestions.
Thank you
iOS location services provide information about the device's position, but not information about the context of the position, such as which city they are near and how close they are to it. Geographic data such as what you're interested in comes at a price, which is why there are commercial SDKs providing it.

I am trying to make a program to change the colour Start Screen of Windows 8 periodically. I've found the registry value to make the change but the problem is that the user must log out then log back in to see the changes. Is there a way to send the system a message or something that changes the colour of start screen instantly like how you set it in the Personalization slider?
I'm using C++ as a programming language and Visual Studio 2012.
Any help would be appreciated.
P.S. I would also like my program to change to Lock Screen picture periodically too. It would be nice if someone could share a pointer to that also.
I don't believe you could set the system theme colour, at least in a Windows Store app. You can't even read from the system theme colour, according to this thread:

My company wants users to be able to gather different documents from our website (for instance, manuals, installation instructions, etc) and put them all in one place (kind of like a shopping cart) to then print out all at once when their visit is over. Are there any applications that I can leverage to do this? We want something that's fairly plug-and-play because this is a late-stage requirement. I feel like I've come across something like this before but can't remember where.
Any suggestions would be greatly appreciated! Thanks!
There should be scripts where it bunches all of the selected documents into a zipfile for you. I've seen it on Joomla sites where you select different modules you want to download and it puts it into one package. Sorry I can't help with actual code.
You say "shopping cart" but are users paying for these documents?
If so, you can outsource the downloads to a third party like PayPal to handle the digital downloads. PayPal API will let you handle a shopping cart.
If not, why not just have a link to a PDF on the document's description page? Then they can save, print, whatever. (My two cents, of course, but I don't see the big advantage to bundling a bunch of documents just to unbundle them on the other end.)

Ok here it goes, hope this is an original idea. Scenario is this. I have hosted a personal website, which contains a wordpress blog as well. I have a windows mobile connected to internet via GPRS.
I want to write an application for my windows mobile, which would track my current GPS coordinates (I don't have GPS but have figured out a way to find out the coordinates), and upload them to my site, where I'd provide a web service which can get or set GPS coordinates. Then I want to display my current location in my blog (as a wordpress plugin) or in another page, where it talks with my web service again to obtain my latest GPS coordinates.
So am I reinventing the wheel or there's a complete solution available for me to achieve such a thing?
Any pointers please. It's not directly programming related, but it sure involves programming!!!
Sounds like Google Latitude.
There are quite few of these types of applications/systems.
I myself have written a similar system to try to recover my phone if it gets stolen.
On codeplex you can find This (not mine).

Does any body know what powers Google Charts? I have been using it for a while but not sure what Google used to build it.
They bought the Gapminder library for doing charts. It's a Java library as far as I know, but they don't seem very anxious to release the code as open-source.
Everything at google is done in C++, Java, or Python. I'm guessing the internals is probably done in one of the latter two.
Mathplotlib was my guess too - ( thanks "davidg" ).
SVG - got my own doubts because you don't have to go the length of server side SVG just to produce a static image. No panning or scaling required so not sure if they used SVG
I feel the touch of SVG there..
Maybe Internal engine to generate and work with SVG and export images as PNG images.
Any other thoughts?
Just guessing here: they must be using Python with some charting library and then returning the produced files. There are a few tools to do charts in Python. Matplotlib and ReportLab come to mind.
What is sure is that you can do it with a Java servlet.
Eastwood is an open source implementation of the Google Chart API.
(powered by JFreeChart)
Probably just libraries they have written themselves, it's pretty easy to throw together a chart drawing library, but hard to do it right. So someone hacked together a custom java/C++/python library using already available stuff to be able to update the graphics of his charts easily, and then it extended.
That's the great thing about it, that you can make your own version without much effort, just change the URL and design your own flash animation of the chart. And that the data available in the graphs is easily webscraped..
Just theory, but something like this is perfect small project to do in 20% of your time.
