I have an idea for an app that would require fetching scheduling information from a website, in particular a local transit company. I have not done any work in WP applications that involves drawing information from the internet, and I have no idea where to start with that.
What is the best way to learn how to achieve this within Windows Phone? Any namedropping of things to look up or places to start would be appreciated.
Your question is EXTREMELY vague, which is notoriously a no no on S.O. so here is a vague answer in return.
WebClient wc = new WebClient();
wc.DownloadStringAsyncCompleted += (s,a) =>
{
var results = a.Result; // Your web result
};
wc.DownloadStringAsync(new Uri(#"http://www.Google.com",UriKind.RelativeOrAbsolute));
If you are interested in a real explanation hit me up on twitter or at amr#AnthonyRussell.info I will try and get you up to speed. StackOverflow is not a place for questions like this.

I have recently been thinking about one of my websites. It's getting big and gaining a community and I have realized; how would I implement new features. Would I code instantly on the website or would I have to pull a backup and code on it then put it back up on the server. Because both methods seem to be inefficient.
Would there be a way that I can do such a thing, like a version system (similar to apps)?
Create a duplicate, test your code until you're satisfied. Check the edge cases. Try to break it. Then, when you're sure it's solid, roll it out to your users during very light usage because you might need to turn off the whole site during the upgrade.
Testing, testing, testing is they key.

I was reading an article about facebook timeline https://www.facebook.com/note.php?note_id=10150468255628920
I always thought this kind of core produces would prefer Cassandra. However it is using MySQL/InnoDB.
Could anyone briefly explain why?
Available internal / external expertise with MySQL (it's easier to google solutions for existing problems)
Cassandra is much harder to reason about due to eventual consistency and limited transaction support
Moving to a new datastore is a lot of pain and it doesn't seem to be justified

I need to build an application in Visual Basic 2010 to connect to a MySQL database. I saw many examples for that, but i've a question:
should the login form be the first or the splashscreen ??
should i check the connection before the login form appears ou after ?
since the application it's going to be used by many people in different places should i implement a secondary authentication method to avoid the non-authorized copy of application ?
Any sugestion or help regarding this matter is appreciated.
It's a legitimate question and from experience this is how I would approach it
When launching the application I would first show the splash screen during that time I would check the connection and determine if they are connected appropriately. If they are connected appropriately I would then show the login screen. If not then show a non-authorized screen. I would also implement a second authentication since your application is used by different sets of users.

You should start with Bootstrap framework, it is created atop of CSS and JS. Here is nice template that you can use as a starting point. SB Admin 2

Does anyone have any ideas on measuring the popularity of an open source project? I thought it would be interesting to create a tools which would compare the popularity of similar open source projects.
The first metric that came to mind was to compare the number of Google results for each specific software, but it seems difficult to programmatically obtain this number (other than scraping it from the direct search page - this also runs into legal issues with Google I believe).
Any other metric ideas? I'd like the end product to be a tool, so metrics which are able to be accessed through code would be preferred.
Thanks,
Chris
If the projects are hosted by platforms like Sourceforge or Github, you can access the number of downloads...
SourceForge offer download statistics;
http://sourceforge.net/project/stats/detail.php?group_id=263007&ugn=dvwa&mode=week&type=prdownload
Google Code have activity ratings.
Maybe you could use those?
