Google Reader+Gears
Relatd javascript Articles
Has anyone tried the Linux version of Google Gears? I installed it like week ago and tried it with WordPress, Google Reader and some other small apps that support it but I felt no effect in speed at all.
Is it just me or did anyone else experience this no speed effect with Linux version of Google Gears?

As I mentioned in my previous post, I’m now using Google Readerin WebRunneras my main RSS aggregator.
A few days ago, Google released Google Gears- it’s a browser add-on that allows various Web apps to work offline by providing them with ways to store and retrieve information locally. As one of its first implementations, Google Gears allows Google Reader to work offline.
While Google Gears installs and works seamlessly with Google Reader in Firefox, there are a few things that need to be tweaked in order to make it work in WebRunner or any other XulRunner application. The actions below are somewhat Windows specific, but something very similar can be done on any platform.
- Register as a global extension- by default, Google Gears installs itself as a Firefox global extension in Windows registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\Mozilla\Firefox\Extensions]
{000a9d1c-beef-4f90-9363-039d445309b8}=C:\\Program Files\\Google\\Google Gears\\Firefox\\
In order to add it to WebRunner we need to add the following key to the registry:
[HKEY_LOCAL_MACHINE\SOFTWARE\WebRunner\Extensions]
{000a9d1c-beef-4f90-9363-039d445309b8}=C:\\Program Files\\Google\\Google Gears\\Firefox\\The exact registry path is different for every XulRunner application, but the basic structure is “HKLM\Software\VENDOR\APP_NAME\Extensions”. In WebRunner case there is no “Vendor”, so it’s just “HKLM\Software\APP_NAME\Extensions”.
- Add WebRunner compatibility to Gears manifest. Locate the Gears extension manifest install.rdf file (typically in C:\Program Files\Google\Google Gears\Firefox), and add the following lines:
<em:targetApplication>
<Description>
<em:id>webrunner@webapps.org</em:id>
<em:minVersion>0.1</em:minVersion>
<em:maxVersion>10.0</em:maxVersion>
</Description>
</em:targetApplication>“webrunner@webapps.org” is the ID of your WebRunner XulRunner application. For other XulRunner apps, you can find out the correct ID in their application.ini file.
- Add Extension Manager support to WebRunner. Locate the main WebRunner application manifest file - application.ini (typically found in C:\Program Files\WebRunner) and add the following lines:
[XRE]
EnableExtensionManager=1
Basically, the first step makes sure that WebRunner detects the extension, the second one makes Gears compatible with WebRunner and the third makes WebRunner load the Google Gears extension. Once you complete these three steps, Google Reader and any other supported Web app will detect and use Google Gears for offline functionality.

What is XSTM?
XSTM is a n open sourcelibrary which enables high performance object replication between processes. It is an object oriented Distributed Shared Memory, or a Distributed Object Cache.
XSTMhas similarities with technologies like Adobe Flex Data Services , JBoss Cache, Terracotta, Tangosol Coherence , ScaleOut , or IBM's ObjectGrid .
Our model is based on object shares, which work like file shares. When an object is added to a share, it appears on the other machines which have the same share opened. Modifications done to the fields of the object are from this point replicated between machines.
Read more in the project overview.
XSTMis made of three projects. The Java implementation is called JSTMand is the base from which
the other versions are derived. An adapted version made with Luciano, the
author of GWM , is available for GWT . It allowsthis library to be used in a browser. NSTM is a .NET port based on IKVM.
All implementations are compatible with each other so object replication can take
place e.g. between a Java server and a .NET Smart Client.
- No plugins like Flash or Java required.
- Popup blockers are no problem. The content expands within the active browser window.
- Single click. After opening the image or HTML popup, the user can scroll further down or leave the page without closing it.
- Compatibility and safe fallback. If the user has disabled JavaScript or is using an old browser, the browser redirects directly to the image itself or to a fallback HTML page.
The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses.
Google Web Toolkit (GWT) is an open source Java software development framework that makes writing AJAX applications like Google Mapsand Gmaileasy for developers who don't speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Javaprogramming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML.
