Since I restarted regularly giving conference talks a couple of years ago, all my talks have been packed to the edges, with people standing. This tells me there is huge ongoing interest in all things Java performance related.

My latest The 10 Common Concurrency Models from this month's Devoxx is just a 15 minute whirlwind tour that explains why there are so many of these models for you to choose from, yet without a clear winner. Heinz Kabutz, my colleague and fellow newsletter writer ( Java Specialists Newsletter) was in the audience and later correctly pointed out to me that ThreadLocal is part of an "unshared" model rather than part of the "atomic" optimistic cannon.

It didn't surprise me that I missed that, this whole concurrency model world is a massive mix of overlapping options and, as with all my talks and articles, I'm trying to impose some clarity so that it's easier to choose what's right for your application. What's clear is that you should make a conscious informed decision rather than drift from one to another (as happened in another of this month's linked talks, "The 7 deadly sins of concurrent programming", see below).

Now on to this month's tips, tools, news, articles, and those talks. And of course the tips from this month's articles and talks, as ever are extracted into this month's tips page.
