social-networking

I've run into the same problem in two different pieces of work this month: Version 1: User 1 & User 2 are friends Version 2: Axis 1 & Axis 2 when graphed should have the quadrants colored... The problem is, I don't see an elegant way, using a RDBMS, to store and query this information. There are two obvious approaches: Approach 1: store the information twice (i.e. two db rows rows per relationship): u1, u2, true u2, u1, true u..n, u..i, true u..i, u..n, true have rules to always look for the inverse on updates: on read, no management needed on create, create inverse on delete, delete inverse

I'm an intermediate PHP developer with no experience building a large scale web application in this language (though I have in others, mainly Rails)...say I wanted to build a social networking site using PHP and MYSQL (preferably) with all the web 2.0 trimmings. Where should I start? What sort of frameworks should I be looking at? Any up to date modern books that would outline something like this? Really anything for building a modern web app in PHP. Ryan, there is a php framework called Elgg which is a php framework directed at social networking based applications. A whole list of them: Top

I would like to create a private customized social networking for my company employees and partners so that they can collaborate, exchange messages, share experiences (events, book references, etc) and be grouped into communities. Does anybody know good Java framework for start developing this? I would be looking for something that would contain basic components such as Profile, Friend List, Community, Events, Messages, etc. Each of this component could be extended to implement domain specific features. It would be nice if it also supports OpenSocial. Shindig is in incubation at Apache : http:

Integrating Multiple Social networks into Android with a single common Framework or API or JAR For iPhone we have ShareKit, which integrates multiple sharing options in one framework. http://www.getsharekit.com/ For android i have no idea if something similar exists. I am building an application which shares information to social networks, like some posts and tweets. Its a simple game, where gamers publish updates about their achievements and levels.. etc.. I used Facebook and twitter APIs but they take up lots of memory and difficult to manage. Also i cannot handle them efficiently. Any help

Social networking website probably maintain tables for users, friends and events... How do they use these tables to compute friends events in an efficient and scalable manner? Jeremy Wall Many of the social networking sites like Twitter don't use an RDBMS at all but a Message Queue application. A lot of them start out with a already present application like RabbitMQ. Some of them get big enough they have to heavily customize or build their own. Twitter is in the process of doing this for the second time. A message queue application works by holding messages from one service for one or more

The relationship is expressed as a matrix x like this: A B C D A 0 2 1 1 B 2 0 1 0 C 1 1 0 1 D 1 0 1 0 The entries refer to the number of connections they have. Could anyone show me how to write it as an edge list? I would prefer to write it as an edge list: A B A B A C A D B C But would this edge list allow me to create a network plot? flodel Using the igraph package: x <- matrix(c(0,2,1,1,2,0,1,0,1,1,0,1,1,0,1,0), 4, 4) rownames(x) <- colnames(x) <- LETTERS[1:4] library(igraph) g <- graph.adjacency(x) get.edgelist(g) # [,1] [,2] # [1,] "A" "B" # [2,] "A" "B" # [3,] "A" "C" # [4,] "A" "D" #

This the some peace of code for twitter ... I want to know how to get the share action view like we get in ios stack photos app... @IBAction func twitterButton(sender: AnyObject) { let image: UIImage = UIImage(named: "LaunchScreenImage.png")! let twitterControl = SLComposeViewController(forServiceType: SLServiceTypeTwitter) twitterControl.setInitialText("") twitterControl.addImage(image) let completionHandler = {(result:SLComposeViewControllerResult) -> () in twitterControl.dismissViewControllerAnimated(true, completion: nil) switch(result){ case SLComposeViewControllerResult.Cancelled: print(
