Programming

In this post I am going to sum up things I have learned while creating a fluent API (or internal DSL) in Java. I'll talk about the search API I created for my current position: it's not a toy problem, it's a real problem, which has a significant amount of complexity. Because of that complexity, you get to see techniques and ideas that you don't usually see in toy examples. I am not including the...

Web Design

 Last week Apple released their latest product destined to change the world (the iPad).  At least that's what they want us to believe.  Perhaps the biggest controversy over the thing is the lack of Flash capability.  However this being java.net I have to wonder out loud, where is Java capability, and more importantly why isn't as much controversy being raised over Java being...

Community

Here it is the PDF version of my slides @Jfokus 2010, the great Java conference in Sweden. You feedback is always welcome. And if you missed that, here you find my conference wrap-up.

So finally, after endless nights, my new web site Head Crashing Informatics is finished. Learned a lot on XHTML and CSS by coding it completely by hand (yes, really, did not use any design tool, as I love to code and always want to see what's going on behind the scenes). In the future you'll find my latest stuff there, research results, code snippets, background information on my projects, and...

I love owls; they are so elegant and have a strong personality (too bad in so many years I've been unable to take photos at any of them!). Unfortunately in my culture (and probably many others) they have also got a bad reputation, as they were considered messengers of bad fortune. It's for this reason that in italian a "gufo" is also a person who, for innate attitude or purportedly,...

Is Go a Java replacement?  Of course not, but I do wonder what Google's up to: http://thoughtfulprogrammer.blogspot.com/2010/01/why-go-googles-very-on-programming.html

THIS IS HOUSTON.... The Silicon Valley JavaFX JUG met for its 2nd meeting on Jan 13th, 2010. SVJAVAFXJUG once again had another rock star speaker in Amy Fowler.

Plus, 40 folks were watching remotely via...

I had the opportunity to attend the Community Leadership Summit (CLS) West Event (wiki, attendee photo gallery, eventbrite registration site, CLS session notes page, etc) this last weekend (Jan 9th, 2010) at the Devry campus in Daly City. It was an unconference event.  Lots of Community Leaders from different Tech Companies were there which was...

J2EE

GlassFish v3 comes bundled with Metro - a secure, reliable, transactional, and .NET interoperable Web services stack. Metro is compliant with JAX-WS and provides additional quality of service attributes that can be easily enabled using NetBeans IDE. This blog contains a screencast that shows how to create a simple Web service using NetBeans 6.8, implement the business logic by accessing a...

Composite components are a great feature of JSF 2.0. The canonical example is a login component with fields for the username and password: <mylib:login name="#{user.name}"      password="#{user.password}"      loginAction="#{user.login}"/> This has been well explained elsewhere....

Converged (Http/SIP) applications gives users the flexibility of creating or accessing information about their communications (call/conferences/im ...) over the web. To make this possible a typical converged application would contain an entry point for all the Http requests, which is mostly an Http Servlet. This servlet would return back appropriate responses by accessing the corresponding...

Security

I received an email from core Mojarra team member Jim Driscoll, who was inexplicably laid off from Sun after its recent acquisition by Oracle, about a talk at next week’s BlackHat Conference in Arlington, VA, U.S.A.. Jim pointed out that two security luminaries from the elite SpiderLabs team from Trustwave are giving a talk at BlackHat about view state security, specifically focusing on...

Web Applications

Yet another week of development is nearly over (at least for me). What was this week all about? Apart from the really low temperatures outside (on Tuesday it was -24C at 4am), I focused mainly on extending the multi-site support in Magnolia. This feature exists for years already. But what it really means in context of Magnolia? In general you can setup the server to run mulptiple domains and you...

There’s this guy, Peter Thomas , and he has this blog entry called “jsf sucks”. I don’t want to increase his page rank so I’m not linking to it here. However, it’s certainly a popular page since it’s the top link for “jsf sucks” on google, bing, and Yahoo!. I have read the entire blog entry, all of the entries linked from it, most of the...

Back in November, Sebastian Hennebrueder published a detailed, thoughtful, and mostly objective analysis of JSF2. I'd like to use this entry to respond to his entry, which may be found at http://www.laliluna.de/jsf-2-evaluation-test.html. I have excerpted the parts of his article that pertain to my comments here. JSF 2 - evaluation and test    Introduction JSF is a standard to...

GUI

In my famous company innoQ I currently have the opportunity to work on a real cool tool: Bundle-Bee. It claims to be able to take any OSGi bundle and distribute the computational load to an ad-hoc grid (e.g. all machines in an office) without special setup or configuration. We just released version 0.5.3 which is still very restricted and far from feature complete - we don't even...

The official press release went out this morning: The Apache Software Foundation Announces Apache Pivot as Top-Level Project To coincide with the graduation, Pivot 1.4 was released a couple of weeks ago, and this morning we launched the new project site at http://pivot.apache.org! We are very proud to be joining one of the most well-respected...

Tools

I've finally managed to produce the Windows installer for Hudson, as originally raised by Håkan Reis. Please try it out and let me know how it works. This one took much longer than the installer for any other platforms, and while I normally think of Microsoft technologies very highly, Windows installers and WiX are a real disappointment. For example, you write the description of the...

Extreme Programming

 Everyone is talking about team work - but what exactly does it entail? Strictly speaking, the word denotes classical work division in which every team member is responsible for a clearly defined section of the entire production process.   We at Micromata have a different view on team work: we want every team member to understand and be interested in their colleagues' areas of...
