Having previously replaced my broken Garmin Forerunner with a new one, my brother sent back his black and white eTrex Legend (which he bought cheap as it contained lead in the solder) as the screen would intermittently display stripes, only to be sent a much more up-to-date colour eTrex Legend HCx. Can’t complain but does make you wonder whether Garmin are capable of fixing anything!

Sunday, December 9th, 2007Cleaning up dumps
Saturday, December 1st, 2007No – this has nothing to do with nappy changing! I’ve spent the past two weeks as part of the support team for a customer’s WebSphere Application Server environment. Although I know all the theory (I’m an IBM Certified System Administrator for Versions 5.0, 6.0 and 6.1) it’s not very often I spend long enough at any one customer to get my hands dirty. My Korn shell scripting, Jython and vi skills certainly improved rapidly during the time I was there!

New JMS benchmark
Thursday, October 25th, 2007The SPECjms2007 benchmark was announced today. The benchmark has two performance metrics covering horizontal and vertical scalability with the tests consisting of a mix of publish/subscribe and point-to-point, durable and non-durable, persistent and non-persistent, and transactional and non-transactional messages. Given the contributing organisations (Technische Universität Darmstadt, IBM, Sun, Oracle, BEA, Sybase and Apache) it will be interesting to watch as results are published.
Flat file custom data bindings
Monday, October 22nd, 2007Having written a very similar exercise for the Connecting Enterprise Application to WebSphere Enterprise Service Bus ITSO Workshop, it was interesting to read Rich Johnson’s article on creating custom data bindings for the WebSphere Flat File adapter. In particular, the step required to actually add the custom data binding so that it shows up in the Enterprise Service Discovery wizard is not exactly obvious.
Best Practices for Large WebSphere Topologies
Monday, October 22nd, 2007If you’re looking to scale out your WebSphere solution then this paper on developerWorks is one you must read. It provides guidelines on cell sizes and discusses when you should consider multiple core groups and how to bridge them, as well as other important considerations. Go read it!
Job ad
Tuesday, October 16th, 2007Couldn’t help laughing at this job ad for a “WebSphere ESB Developer”. On closer inspection said developer needs “proven experience of WebSphere Message Broker V6” i.e. the “Advanced Enterprise Service Bus”!
JMS problem determination
Friday, October 12th, 2007The JMS Problem Determination Redpaper covering WebSphere Application Server Version 6.1 was published at the start of the month. As the long list of authors indicates, Rich Coppen has done a fantastic job in getting input from the whole of the development team so this is a pretty comprehensive resource.
Ruby and Zero
Sunday, October 7th, 2007Out of the box, Project Zero supports PHP and Groovy as scripting languages but, as this developerWorks article demonstrates, extending Zero to support other languages is pretty trivial. In this instance, they show how adding support for Ruby (specifically JRuby) can be achieved with one simple class. Now Rails developers have no excuse not to take a look at Zero!
