Clean URL's

Forward servlet has been included into JSOS.

This servlet lets you implement clean url's in your web applications. Servlet is acting as a front controller to your JSP files. E.g. you can have an original request /servlet/foo/bar and serve it as /foo/bar.jsp etc. Servlet automatically forwards original requests to the appropriate JSP's processing depends on the path.

"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.

Google's idea for HTTP replacement. Interesting read. The bad things that we need replace not only servers but browsers also. If it is not Chrome :-)

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.

Amazon services for Android

"The AWS SDK for Android provides a library, code samples, and documentation for developers to build connected mobile applications using Amazon Web Services. Example applications developers can build with the AWS SDK for Android include:

A media application that uploads photos, videos, and more to Amazon Simple Storage Service (Amazon S3) for world-wide distribution through Amazon CloudFront.

A social game that shares moves, high scores, and other data between devices using Amazon SimpleDB.

A messaging client that broadcasts messages between devices using Amazon Simple Queue Service (Amazon SQS) and Amazon Simple Notifications Service (Amazon SNS), without requiring any additional server infrastructure." - Amazon Web Services SDK for Android. Source code included - github.

Looks interesting. They (Amazon) also provide the similar component for iOS.

Mobilize your data

Our mashup QR code maker has been updated. It is probably the simplest way for getting your content to mobile web. Simply copy-paste any text and service will create for you:

- a mobile web page with this content (landing page)
- QR-код for the fast loading that page right into your mobile browser
- HTML for publishing this QR-code on your own site (blog etc)

And of course, you can simply print QR-code and stick to the some real object.

You can publish any text with this mashup. For example, in the simplest case you can just publish a link (URL). And QR code generation mashup will prepare for you a page for the mobile downloading.

Mobile pages created with service include social buttons (Facebook, Twitter, Emai). So the content on the mobile page could be simple published to Twitter and/or Facebook for example. From this point of view mashup’s functionality could be explained so: create QR-code for publishing to Twitter (Facebook).

P.S. you can see all QR-code related tools on the dedicated page: QR code how to
