Ola Bini, a core JRuby developer and author of the book Practical JRuby on Rails Projects, has been developing a new language for the JVM called Ioke. This strongly typed, extremely dynamic, prototype based object oriented language aims to give developers the same kind of power they get with Lisp and Ruby, combined with a nice, small, regular syntax.

Data storage and analysis for the largest scientific instrument on the planet (LHC Grid)
October 1, 2008
The Large Hadron Collider (LHC) is a particle accelerator that aims to revolutionize our understanding of our universe. The Worldwide LHC Computing Grid (LCG) project provides data storage and analysis infrastructure for the entire high energy physics community that will use the LHC.
The LCG, which was launched in 2003, aims to integrate thousands of computers in hundreds of data centers worldwide into a global computing resource to store and analyze the huge amounts of data that the LHC will collect. The LHC is estimated to produce roughly 15 petabytes (15 million gigabytes) of data annually. This is the equivalent of filling more than 1.7 million dual-layer DVDs a year! Thousands of scientists around the world want to access and analyze this data, so CERN is collaborating with institutions in 33 different countries to operate the LCG.

FireStatus, the Firefox plugin for status updating on multiple social networks, is out!
September 30, 2008
It has been several months since we got together with Panagiotis and Christos to make a Firefox plugin that would allow us to send status updates simultaneously to multiple social networks and services, like Twitter, FaceBook, etc. As a part-time project (actually one of many part-time projects I’m constantly working on), it took us a while but we have a beta version out.
You can visit the project page, the FireStatus Google Group,the FireStatus FaceBook page or check out the buzz on the twittersphere.
And don’t forget to leave a review here.
PS: We’d like to thank our #1 beta tester Costas for his valuable feedback!
UPDATE: See Christos’s blog post on the story behind FireStatus.

Report from the SpringSource Seminar Day in Athens
August 25, 2008
The Hellenic Java User Group and SpringSource has presented the free Spring seminar in Athens today. This Seminar was 4-hours long with 3 talks by Iwein Fuld, consultant at SpringSource based around the Spring Portfolio and the SpringSource Application Platform.
The sessions started around 1.30 PM and covered:
- SpringSource Portfolio
- What’s New in Spring 2.5
- Plans for Spring 3.0
- Building a Web App with SpringSource Application Platform (Demo)
Although there was a severe heat wave and most people are still on vacations the turnout proved very good and Iwein created a warm and friendly atmosphere. Participants left with several Spring leads to investigate the following days.
Oracle has announced the release of WebLogic Server 10g R3 which is the first release of BEA’s Application Server since its acquisition by Oracle earlier this year.
This version adds support for Java SE 6, Spring, Comet, improved Operations Control, FastSwap Deployment and more.

Bye bye Internet Explorer 6
July 21, 2008
Since attaining a peak of about 95% usage share during 2002 and 2003, Internet Explorer 6 (IE6) has been rapidly losing market share. As the end of 2008 approaches, significant online services, vendors and web frameworks are dropping support for IE6 (Apple, 37signals, etc.)! Will this (finally) year be the end of IE6..?
Includes original quotes by:
- Douglas Crockford, senior JavaScript Architect at Yahoo and creator of JSON
- John Resig, who is a JavaScript Evangelist for Mozilla and creator jQuery
- Dylan Schiemann, CEO of SitePen and co-creator of Dojo

What Do You Want On Future Browsers? Time to Vote!
July 4, 2008
“An industry wishlist for future browsers has been collected and developed by OpenAjax Alliance. Using wiki as an open collaboration tool and with contributions from many people in the industry, the feature list now lists 37 separate feature requests, covering a wide range of technology areas, such as security, Comet, multimedia, CSS, interactivity, and performance. The goal is to inform the browser vendors about what the Ajax developer community feels are most important for the next round of browsers (i.e., FF4, IE9, Safari4, and Opera10) and to provide supplemental details relative to the feature requests.”

After a rather long development cycle the JBoss AS 5 RC1 is only a handful of days away from its release. InfoQ caught up with project lead Dimitris Andreadis to discuss the new features and release timeline. Dimitris also comments on Java EE 6 features, the advantages of JBoss AS with respect to competition and their choice of having a pluggable components model instead of sticking just to OSGi:
Grizzly and the New Atmosphere Comet Framework: Q&A with Project Lead Jean-Francois Arcand
June 20, 2008
The Grizzly framework is used in multiples products like GlassFish, Sailfin, RESTlet, OpenESB and many more, where it enables developers to write scalable server applications, by leveraging the Java New I/O API (NIO). Atmosphere, an evolution of Grizzly, is a POJO based framework that aims to bring Comet to the masses. Jean-Francois talks to InfoQ about this new development:

“WRITE ONCE, DEBUG EVERYWHERE”
Manik Surtani – JBoss Cache: Clustering enterprise Java for scalability and high availability
Manik’s visit to Greece, was a very good opportunity to chat with him and arrange for an interview/acrticle for InfoQ about JBoss Cache. During his talk he presented the benefits of caching and also the common pitfalls. He also presented several features of JBoss Cache and common architectures for high availability.
Very excited to blog about the upcoming JHUG Java Day that is organized by the Java Hellenic User Group (JHUG).

From twitter users I’d suggest looking for #jhug. Also I suppose a FaceBook event would sound nice…
Article on InfoQ.com:
At the JavaOne bookstore I got my hands on a book by Elliotte Rusty Harold about HTML refactorings. As I was skipping through contents I noticed the following refactoring:
Replace Flash with HTML: Convert Flash sites to HTML. Provide pure- HTML alternatives for Flash content.
… and it followed:
Flash is extremely inaccessible. I most cases a Flash site might as well be a black box to blind users, and is often hostile to color-blind, deaf and motion impaired users as well…
It is not a secret that I have a bias opinion when it comes to Flash/Flex and I’m happy that there other people also that are immune to this hype.
Of course the lift of the restrictions regarding the SFW/FLV spec was a very positive think on behalf of Adobe and I hope they keep it up!
The queue for this session was huge and started outside of the Moscone center. It was interesting and well organized but the characterization “advanced” was not very accurate. Of course you cannot have any “advanced” presentation on a crowd of hundreds and you should give Jeremiah and Joe the credit for keeping a good balance.
Here are some points that are not very trivial:
- You can mess with your friends Google search history with simple basic CSRF
- The OWASP servlet filter is a nice tool
- Mentioned a way to make a double cookie check both on the body and the HTTP headers and said that it was the way DWR works, but didn’t quite elaborate on it.
- They mentioned several times that there is a wrong and right way to use JSON and it would be nice to provide more details but I suppose time was an issue.
- Maybe the corner stone of JavaScript hacking is the action to override Object(). This is also a nice way to do AOP.
- There are many-many places where JavaScript is executed in a web page besides the <script> element like attributes (javascript:), event listeners, browser specific event listeners, CSS (inline and imports), etc. so…
- … you might consider using AntiSamy
- With XSS you can grab the secret token and then launch a CSRF
Some things that I feel that should also be added in a similar presentation should be:
-
- Application layer firewalls like mod_security
- Hacking browser extensions that users typically have like firebug, Greasemonkey, etc.
- Protecting your app from malicious JSON
- Browser standards compliance mode (IE8 ) as a way to protect from attacks that aim at malformed HTML
