I've also written about them in the FusionAuthority Quarterly Update, if you happen to get that great magazine. Most recently I did, "FusionReactor: ColdFusion Server HealthCare (and What's New in Version 3)", in Volume ii Issue iv (Summer 2008), and a couple of years ago I did, "FusionDebug Explained: Interactive Step Debugging for CFML", in Volume i Issue ii (Fall 2006).
I'll also have news coming up about more cool stuff coming from the folks, including FusionAnalytics and FusionReactor Enterprise Monitor, both discussed in the FusionReactor Labs, as well as the recently released AIR Enterprise Dashboard, recently promoted from the labs to an available product.
Until then, go enjoy the discount code to get these great products, which help you with debugging and monitoring whether you run on CF 6, 7, or 8. (For more on why they still matter even with CF 8, see this previous entry.)
