This week's book giveaway is in the Other Languages forum. We're giving away four copies of Functional Reactive Programming and have Stephen Blackheath and Anthony Jones on-line! See this thread for details.
visual paradigm is an over kill, it's an entire modelling tool plus once i accidently chose to install the modeler edition it won't budge from it even though i tried to change it later in code engeering section.
maintainj is too pricey (500$ a user per year??)
javaCalltracer had potential however it kept crashing when i started the application, i suspect memory problems.
code logic never worked, even it's installation was problematic at best, (windows 7 reverted to basic color scheme)
of all these heatlamp seems to be closest, (and cheapest at 129$) however it's still in beta, so i'm wondering if there are any other options.
