I was recently discussing with a colleague on how to do caching inside of WebSphere Process Server (WPS). A few days later I stumble upon a blog post linking to a developerWorks tutorial on this exact topic. Good timing, Andrew! :-) [via SOA Tips 'n' Tricks blog]

Olivier has now completed moving the objc-s3 repository from subversion at google code to github. Future development will be done in the new objc-s3 repository.

We all know software maintenance is important, but sometimes we still don’t realize how important it really is. Planning and design is an integral part of good software maintenance and its importance will only grow with the advent of service oriented architectures. CACM in its most recent issue published a great article by Paul Stachour and David Collier-Brown about software maintenance, describing its history, methodology, and its increase in importance since the introduction of distributed systems.

Why haven’t I heard about the junkcode talk by Andrew Tridgell in the last five years since it was presented? This is genious. [via rene.bz]

The Apache Foundation and CollabNet announced that Subversion has entered the incubation phase and plans to become an official Apache project.

Given that Brian Behlendorf is on the board of directors and a co-founder of CollabNet this is not too surprising, but it’s an interesting development.

Interesting discussion going on over on Jacob Kaplan-Moss’ blog after he posted his Twenty questions about the GPL. [via esa]

This nicely complements the derivative works question I posted last month. I especially recommend to read VanL’s comments. Very insightful!

Together, VMware and SpringSource plan to further innovate and develop integrated Platform as a Service (PaaS) solutions that can be hosted at customer datacenters or at cloud service providers. These solutions will allow customers to rapidly build new enterprise and web applications and run and manage these applications in the same dynamic, scalable and cost-efficient vSphere-based internal or external clouds that can also host and manage their existing applications, providing an evolutionary path to the future. – VMware’s press release

If you want to know if you can really run some PHP on GAE, what’s the first thing that comes to mind? Right… Try to run WordPress on GAE, of course :-)

Although not very practical, it’s still a very cool demo :-)

Infrastructure changes to servers or bandwidth are one way to increase the performance of your web applications, but most of the time there are things you can do to make your web applications faster without costly investments in infrastructure and Google Page Speed is an interesting tool to help you with that. [via Google Code Blog]

Page Speed is an open-source Firefox/Firebug Add-on. Webmasters and web developers can use Page Speed to evaluate the performance of their web pages and to get suggestions on how to improve them.

JavaOne 2009 ended a long time ago and I’ve been back in Vienna for a few weeks now. In the mean time I’ve had the time to go through the sessions again and compile a list of sessions I liked most.

At the moment they only have the PDFs available, but there should be recordings coming for some of those sessions.

• TS-4118: Practical Lessons in Memory Analysis
• TS-4238: HtmlUnit: An Efficient Approach to Testing Web Applications
• TS-4407: Best Practices for Large-Scale Web Sites: Lessons from eBay
• TS-4887: Garbage Collection Tuning in the Java HotSpot Virtual Machine
• TS-5427: Inside Out: A Modern Virtual Machine Revealed (Sun)

If you found this list interesting you might want to look at all the other sessions presented at JavaOne 2009.
