Time-aggregated graph

"What new things could we discover if social network analysis took time and space into account, in addition to the raw connections between people? In most cases, social network analysis today is limited to discovering friend connections, community leaders and outlines, influential people and personal friend recommendations - in a static or snap-shot kind of way. If new factors could be taken into consideration, specifically changes over time and space, then social network analysis could discover things like emergence or decay of leadership, changes in trust over time, migration and mobility within particular communities online. That's very valuable information that the social web has barely begun to tackle capturing." - from here.

A very interesting read. Time as a factor in the soical graph analysis.

Convergent servlets

SIP+HTTP: "The values of asynchronous processing of requests in a converged HTTP/SIP application are tremendous. Having asynchronous processing in the game, there is no need to send an HTTP request in order for the UI to get updated, this can happen every time a new SIP message arrives.
Any action initiated by the sip endpoint will update the web application and vice versa. For example, when a new user registers, the REGISTER message will update the page to display the new user, and when the client clicks to call this new user, the sip endpoint will start ringing and so on.
A converged application will now be able to follow, present and react almost in real-time on every event that initiated from or destined to the HTTP/SIP Servlet container by any client, either a sip endpoint or a web browser." - from here.

Pay by social network posting

It is a new business model for QR-code usage. Lets us see for example check-in model in Foursquare. Users check-in, service writes this information into user’s timeline and business delivers some benefits for the customers. And check-in information is on the practice a link to the services itself rather that a link to the business. So why do not make this process more logical at the end of the day? Ask users to put business related info into his her time line/wall etc. and deliver back some benefits (coupons, discounts, gifts, some free stuff etc.). So business will deliver benefits for the links in the social networks.

It is exactly what our service QRpon is about. This service lets any business create a mobile site for publishing data in social networks in exchange for some confirmation (coupon, discount info etc.) The process of creating mobile site is simple. Just set some text information about your business/offering, set a text for publishing in the social network and text for the confirmation. QRpon service will create a mobile site as well as QR-code for it. You can test this site (process) using this QR-code. If everything is Ok, just print this QR-code and place it on your business site. This QR code presents a physical (on-site) checkin for the customers.

End user can scan QR-code right from his/her phone, open mobile web site andyou’re your info/offering. If user is agreed, he/she can login to social network (right from the mobile site, there is Facebook connect button). Site will automatically publish your data (see above) to user’s wall/time line and return back the confirmation screen. This screen (e.g. coupon) could be presented to the staff for getting benefits. In other words it is like QR-code for coupons – that is the where the name QRpon comes from.

You can treat this service as pay links in the physical words. Customer pays for benefits by placing business data in the own social graph. Customer will get the benefits; business will get the social networks marketing. And the process works without the intermediate broker (read- without the checkin/places services).

On the main page QRpon service you can see a test QR-code. You can scan it and see how does this process work. For the accepting you need to login with your Facebook ID.
And for your own action just click 'Create QRpon' link. Set service info(description), text for publishing and the confirmation. Mobile web site generated by the service works with any HTML5 browser, so you can use it from iPhone, Android, Samsung etc.

P.S. and here you can create customized Like buttons

P.P.S. and here you can a huge list of services and mashups with QR-codes: QR-code how to.
