The New WinRT SDK and Demo

With the introduction of Windows 8, a new application architecture, namely Windows Runtime or WinRT, was also introduced.

WinRT, which has to be used for an application to be published on the Windows Store, is not fully compatible with the old .NET framework. But don't worry, we've got you covered again: with the release of Lightstreamer 5.1 we have made available a brand new WinRT client SDK that can be used to develop Lightstreamer-enabled Windows Store apps.

How to Upgrade to Web Client Library 6 and Later

Lightstreamer JavaScript client version 6 brings some new interesting features and some long-awaited changes. This time we’ve chosen not to pass from the deprecate-first remove-then path as we’ve always done: in fact the entire API was completely designed from scratch to be more flexible and easy to use. Unfortunately, this also means that some effort is necessary to migrate your code based on Lightstreamer HTML Client 4 or 5 to the new Lightstreamer JavaScript Client 6 and later.
This guide was written to help you with the migration. Only the simplest way to do the porting is illustrated; it is obviously possible to use more complicated techniques. Also following only the guide you will not exploit many of the new capabilities of the library, so, before doing the porting I suggest you to check the changelog, the new Development Guide and the Tutorial.

Dynamic Bandwidth and Frequency Management

If you have been knowing Lightstreamer for a long time, you appreciate that it has always been particularly good at managing the bandwidth used by the stream connection and the individual update rate of each subscription.

In addition to heuristically spot network congestions and adapting the data flow automatically, Lightstreamer has always offered an API call to dynamically change the maximum bandwidth granted to a given stream session.

The good news is that now both Lightstreamer 4.1 and 5.0 allow you to change the maximum frequency granted to each individual subscription on the fly.

Lightstreamer in a PhoneGap app

[UPDATE 2014]The original hello world application was simplified by the PhoneGap team. We adapted our own demo to be as close as possible to the original one. As a result some of the descriptions of this article are a bit outdated. Most of it is still valid though, so you can safely go on reading.[/UPDATE]

As a JavaScript guy and mostly-OS-agnostic kind of person I wait for the day when I will be able to fully exploit the power of ApplicationCache and other new JS APIs such as GeoLocation and IndexedDB, to install the same web application and have the same OS-integrated experience on my Windows notebook, my Sabayon box or on my Android Smartphone. Not to mention the pleasure of sharing the exact same app with my iOS, Windows Phone or Tizen oriented friends.

Also, as a developer, not having to develop a native application per each OS out there would be a big plus.

Start Me Up!

No, we are not talking about the old, amazing Rolling Stones Song. We are just enthusiastic to introduce the Startup Program, a way Weswit can provide promising new businesses with Lightstreamer technology at an exceptionally generous rate.

We are more than sure that smart tools are mandatory requirements to transform a good idea into a great success. Many promising start-ups need real-time data streaming for their ideas to take off, but they simply can't afford the additional investment in the early stages. We think that if some companies are given the chance to thrive, we can thrive with them: that's why we decided to offer Lightstreamer only to a few, valuable start-ups every year.

Proud to Be a Component of the Eco-District Technology Environment

by digitalart
An Eco-District is a small-scale area such as a neighborhood or a district with a community commitment to achieving neighborhood-scale sustainability. Smart Grid is one of the key features included.
The Smart Grid is a vision of the future electricity delivery infrastructure that improves network efficiency and resilience, while empowering consumers and addressing energy sustainability concerns. To make the grid "smarter," and capable of addressing the need to decarbonize generation sources and enable end-user energy efficiency, utilities will have to improve observability and controllability of their networks, while transforming them into geodesic structures that intersperse a variety of distributed energy resources – some owned and operated by consumers.
