ETag Article

My article on Using ETags to Reduce Bandwith & Workload with Spring & Hibernate went up on InfoQ today. I'm now waiting in trepidation to see what sort of feedback it gets. Hopefully, I haven't overlooked something obvious. It was fun pulling it together, as I don't get that much of an opportunity to get hands on keyboards these days. I am thinking that if there is enough interest, I make give this open source idea that I've been hearing about a shot and create a project around it.

Update 2007-07-20: There have been a couple of good follow ups on the article:

• Bill De Hora's compares the cultural design centrers of the Spring/Hibernate (Java), Djanjo and Rails communities: "I suspect designing for the Web instead of around it is at least as important as language choice"
• Dare Obasanjo gives a nod to Bill's article by taking a back handed shot at Spring/Hibernate: "It will use a Web application development framework that enables rapid Web development which is designed for the Web as opposed to having some HTTP related features being bolted on". Dare is fooling around with a Facebook application built on AWS. Hmm... Facebook... PHP right? I wonder if that qualifies as one of those "designed for the web" thingies?

InfoQ OSGi Interview

I was interviewed by InfoQ a couple of weeks ago on why we are choosing OSGi for our next generation architecture.

"I believe that in a couple of years time it (OSGi) will also be seen as the de facto standard when architecting IT friendly, service oriented enterprise-scale Java apps"

Screen Scraping Web Service

Interesting discussion going on over here where eBay would like you to pay them so you can build a product that will help market their product. Here's a thought: Use AppConnector to screen scrape eBay, then access it via your own web service.

While we are it - I have to respond to this comment by Jeffrey McManus (head of the eBay dev team):

scraping the site is a really bad idea, not just because it’s “against the rules” but for technical and stability reasons

This is not strictly true anymore - Screen Scraping (or Presentation Integration as we like to call it) has progressed a bit since the 80's. AppConnector is smart enough to detect changes like this. Besides, I really doubt that eBay changes the names of form elements every two weeks - it would mean changing their own systems to cope with it which would be cost prohibitive, not too mention a waste of time for the QA guys.

AppConnector Ranking

Thanh notes we now get #1 billing with Google for our own product (AppConnector), and suggests we should be going for "Desktop Application Integration". I think "Presentation Integration" is a more disruptive descriptive term, but in the end it's all the same - integration done on the glass.
