For the first time this month we accepted a job advertisement (you should be able to see it in one of the box adverts). Naturally, the advert is for a Java performance position. If this works out, we will accept further requests to advertise positions - as long as they are targeted at our Java performance readership.

We are now supporting the London JSIG. Anyone who would like to give a relevant and interesting presentation please contact us and we'll be delighted to discuss your proposal. For those of you who can make the next meeting at the end of January in London, Sun's Simon Ritter will be presenting on the new 5.0 features. Having seen Simon present previously, we are looking forward to an informative and entertaining presentation. Plus freebies!
