SHOULD YOU UPGRADE?

Upgrading is recommended in the three cases below:

"Implementing the Real-Time Web" - Video Now Available

In 2008, Alessandro Alinone (Lightstreamer's CTO) gave a talk in Bangalore (India) at the Great Indian Developer Summit, titled "Ajax and Comet: Implementing the Real-Time Web".

The video of the talk is now publicly available:

Tutorial on using Flex AMF with Lightstreamer

A new Lightstreamer tutorial has been published, covering the use of native Flex AMF objects, a new feature of Lightstreamer 3.6.

The tutorial shows how to push binary ActionScript objects directly to a Flex application in real-time, using AMF (Action Message Format), which is used for serializing binary ActionScript objects in order to transmit them over the wire).

Read the full tutorial.

Lightstreamer 3.6 is out!

I'm very happy to announce that we have publicly released updated versions of all the Lightstreamer components, with many improvements and new exciting features, including: the official Silverlight client, AMF support for the Flex client, efficient bidirectional push for the new faster JavaScript client, a new threading model for the Server, and much more.

After downloading the new package, please remember to get updated licenses. If you are a Moderato user, just generate a new license online. If you are an Allegro/Presto/Vivace user with a valid support contract, please get back to us.

SSL/TLS protocols renegotiation vulnerability (Lightstreamer is safe)

Very recently, a new vulnerability in the SSL and TLS protocols was discovered, which may allow attackers to execute an arbitrary HTTP transaction. It seems that many SSL/TLS libraries will need to be patched in order to prevent such vulnerability.

A global update on the issue is available from CERT.

We have checked the Lightstreamer Server code and we can confirm that Lightstreamer is not affected by this vulnerability.

JQuery Grid (jqGrid) Demo

We have released a very simple demo showing how to integrate Lightstreamer with JQuery Grid Plugin. jqGrid is a nice widget with many advanced features for creating and managing tables.

The integration is straightforward, based on a few lines of JavaScript code that act as a bridge between Lightstreamer and jqGrid.

Concrete Comet Examples

A new article, "Concrete Comet Examples", was published on Comet Daily, featuring some Lightstreamer widgets running live within the page.

The article summarizes and demonstrates three typical applications of the Comet paradigm: financial market data distribution, chats, and monitor consoles.

New Demo Gallery

I'm very happy to announce that we recently released a brand new demo gallery for Lightstreamer.

The online demo applications are grouped by client-side technology, based on the categories below:

• HTML & JavaScript
• Third-Party AJAX Frameworks
• Flash - Flex - AIR
• Silverlight
• .NET
• Java SE
• Java ME
• Others (Excel, iPhone)

Ozone Browser

I just tested version 0.9 of Ozone, a new browser for Symbian phones.

It is based on the WebKit engine and seems to be very fast and compliant to standards.

Lightstreamer Web Client works great on Ozone :-)

Mozilla Prism and Lightstreamer

With Mozilla Prism you can package a web application as a desktop application. You can launch it from a desktop icon and have a browser process dedicated to the application, so that it runs in full isolation.

Lightstreamer works great with Prism, as shown in this video:

GroovyDB Uses Lightstreamer for Web Push

GroovyDB is an appliance made by GroovyChannel that provides "SQL Virtualization" technology. It will be offered as a hosted "Cloud" service too.

They recently added Web Push capabilities, so that any changes to the data are reflected in real time through a Web front-end. The Comet Server used by GroovyDB is Lightstreamer.

Their site hosts a live demo of news pushed in real-time from the GroovyDB.

The Lightstreamer Adapter code they developed is available for download.

The Adobe AIR version of the Flex Stock-List Demo for Lightstreamer is now available.
The download link is available from this forum thread.

A beta version of a Silverlight client library for Lightstreamer has been released today.
It is generally available, as part of a public beta-test program open to anybody.
