InfoQ.com is a next generation web app/portal implementation combining the latest advancements in portal technology (JSR 170) and web development (WebWork, Spring, AspectJ). In this presentation, Alexandru Popescu and Floyd Marinescu walks through the good, the bad, and the ugly of building InfoQ.com; from initial requirements (or lack theoreof), designs, implementation choices, and deployment issues, and all the lessons learned along the way.
In the talk, they examine some of the most interesting features of the site and show their implementation in the web layer, domain model, and DB of a modern tag-driven CMS approach that is the foundation of InfoQ.com.
From the presentation:
Our experiences with JCR
Pros
- storage schema (JCR doesn’t impose a fixed schema)
- Search built into the spec (Jackrabbit ships with Lucene)
- XPath query language
- Support for versioning
- Support for locking
- Data portability - import/export between JSR 170 implementations and storage systems
- Hierarchical schema makes i18n easy
Cons
- Lack of tooling - no SQL Explorer/data admin tools
- Lack of convenience frameworks (ie: Hibernate, etc)
- Very different and unusual compared to common stacks
- No established, documented best practices / patterns
- Lack of trained developers / resources
Set aside 50 minutes and find out how InfoQ.com really works.

I click play, but the video never really starts, it seem to freeze at the screen of the big play thing image/button
Hi Ali
Did you try clicking the big Play button?
if that doesn't work i suggest closing all your browser windows and opening the page again.
i just tested it on both IE and Firefox and it works :)

Actually, I have the same problem as Ali M.: the video never starts playing (neither in FF nor Opera). It might be a proxy issue.
I stand corrected - it does work, but streaming doesn't work (meaning I have to sit through the complete download of the file), due to the proxy I'm behind (as I suspected).
Please install Latest Real player version.On the screen it will appear a tag Download Video.So,video will be available for off line also.I have downloaded many video using real player.
please make a link to download videos. thanks
i agree with Alireza Tajary ,it's better if i can download it and see it on other device.
i wanna download the ppt. where can i download it or send to quarph@gmail.com thank u very much
Being able to download the movies would be very useful, especially so I could view them on a portable devide (e.g. IPod touch). Are there any plans to allow this?
I am also intrested in the ppt..
Yes, downloadable videos please!
