Open source cloud

Yahoo is developing an internal cloud-serving engine to boost its own productivity, and intends to release the code as an open source this year.

"We're committed to open-sourcing all of our cloud infrastructure, for the simple reason that we don't believe the cloud infrastructure is a competitive differentiator for us," says Todd Papaioannou, Yahoo's vice president of cloud architecture. "I have this question pop up from time to time, 'Is Yahoo ever going to move into the cloud?' And the answer is, 'No. We are the cloud.'" - from here.

Geo Messages project

Our Geo messages project has been updated. Lets you share location info on the peer to peer basic as a signature to the standard messages (email, SMS).

Lets us repeat here the main idea. It is obvious, that the question "where are you" is one of the most often asked during the communications. 600 billion text messages per year in the US ask "where are you?" – as per Location Business Summit 2010 data. A huge amount of mobile services is actually being built around this question so their main feature is user’s location exchange. In the most cases it is implemented as the ability for the mobile user (mobile phone owner) write down own location info in the some special place (special mobile application). But it means of course, that user must be registered in location-sharing service (e.g. download some special application). And what is even more important – everyone who needs this information must use the same service too.

Typically we have now two models for location sharing in services. At the first hand it is passive location monitoring and future access to the accumulated data trough some API. It is Google Latitude for example.
Possible problems are privacy - some third party tool is constantly monitoring my location and what is more important – saves it on the some external server as well as the shorted life time for handset’s battery.

Another popular model for location sharing are check-in procedures in the various forms. Check-in could be an active (e.g. Foursquare), when user directly sets his/her current location or passive (e.g. Twitter) when location info could be added to the current message (status). But here we can see not only privacy issue - all my friends/followers can see my location but also a noise issue – my location info could be actually interested only for the physical friends. For the majority of followers my location info (e.g. Foursquare status in Twitter time line) is just a noise.

Our idea of the signed geo messages service (geo mail, geo sms) based on the adding user’s location info to the standard messages like SMS or email. Just as a signature. So with this service for telling somebody "where I am" it would be just enough to send him/her a message. And your partner does not need to use any additional service in order to get information about your location. He/she will simply read SMS or email.

It is obviously peer to peer sharing and does not require any social network. Our location signature has got a form of the link to some mobile map with the marker at the shared location. And what is important here – the map itself has no information about the sender and recipient. That information exists only in the message itself. The map (marker) has no information about the creator for example. That is all about privacy.

There are several implementations for this approach: mobile web mashups (HTML5), mobile web widgets, Java Card applets for legacy phones, JME midlet for mobile Java phones as well as solutions for web applications.

See more details on Geo Messages page.

For example, our Geo Message application for Android has been updated too.

Compress filter

Java servlets filter that lets you compress (gzip) output. Now with cache support - you can compress files only once for example (during the first request).

A new approach for advertising in social networks

Our project QRpon has been updated. It offers a new approach for advertising in the social networks.

Qrpon is a specialized CMS that lets any business create a mobile web site for delivering coupons, gifts, discounts etc. And mobile users will get benefits in exchange for posting business related data (business-defined info) in the social network.

For example, mobile site that offers some discount for a particular product. Mobile user enters web site, accepts an offer, confirms his/her Facebook ID and some business related data will be post on his/her wall. In exchange for this post user will get a confirmation screen that could be presented to the business staff as a confirmation for benefits claim.

No special registration, no downloaded applications. Just a mobile Internet. Any HTML5 browser (iPhone, Android, Samsung etc.).

And mobile site could be easily presented on-site with QR-code. It is also created by our CMS (here the name QRpon comes from).

So why business should deliver benefits in exchange for Foursquare checkin for example? Why do not create own "checkin" site and deliver benefits in exchange for posting business-defined data (not Foursquare-defined)?

You see also the following article – how to pay by posting in Facebook.

P.S. By the way, technically mobile site can show responses (coupons, discounts) depends on the size of user’s social graph ...

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.

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.

SPDY

"As part of the Let's make the web faster initiative, we are experimenting with alternative protocols to help reduce the latency of web pages. One of these experiments is SPDY (pronounced "SPeeDY"), an application-layer protocol for transporting content over the web, designed specifically for minimal latency. In addition to a specification of the protocol, we have developed a SPDY-enabled Google Chrome browser and open-source web server. In lab tests, we have compared the performance of these applications over HTTP and SPDY, and have observed up to 64% reductions in page load times in SPDY." - SPDY: An experimental protocol for a faster web.

Geo Messages

Our Geo messages project has been updated. Lets you share location info on the peer to peer basic as a signature to the standard messages (email, SMS).

It is obvious, that the question "where are you" is one of the most often asked during the communications. 600 billion text messages per year in the US ask "where are you?" – as per Location Business Summit 2010 data. A huge amount of mobile services is actually being built around this question so their main feature is user’s location exchange. In the most cases it is implemented as the ability for the mobile user (mobile phone owner) write down own location info in the some special place (special mobile application). But it means of course, that user must be registered in this service (download some special application). And even more important – everyone who needs this information must use the same service too.

Typically we have now two models for location sharing in services. At the first hand is passive location monitoring and future access to the accumulated data trough some API. It is Google Latitude for example.
Possible problems are privacy - some third party tool is constantly monitoring my location and what is more important – saves it on the some external server as well as the shorted life for handset’s battery.

Another popular model for location sharing is check-in procedure in the various forms. It could be an active (e.g. Foursquare), when user directly sets his/her current location or passive (e.g. Twitter) when location info could be added to the current message (status). But here we can see not only privacy issue - all my friends/followers can see my location but also a noise issue – my location info could be actually interested only for the physical friends. For the majority of followers my location info (e.g. Foursquare status in Twitter time line) is just a noise.

Our idea of the signed geo messages service (geo mail, geo sms) based on the adding user’s location info to the standard messages like SMS or email. Just as a signature. So with this service for telling somebody "where I am" it would be just enough to send him/her a message. And your partner does not need to use any additional service in order to get information about your location. He/she will simply read SMS or email.

It is obviously peer to peer sharing and does not require any social network. Our location signature has got a form of the link to some mobile map with the marker at the shared location. And what is important here – the map itself has no information about the sender and recipient. That information exists only in the message itself. The map (marker) has no information about the creator for example. That is all about privacy.

There are several implementations for this approach: mobile web mashups (HTML5), mobile web widgets, Java Card applets for legacy phones, JME midlet for mobile Java phones as well as solutions for web applications.

And this update introduces Android application: Geo SMS. See more details on Geo Messages page.
