Nudge Theory and Graphical User Interfaces

Nudge theory is an intriguing fairly new take on how to manage societies and modulate the behavior of people to make them behave in a “better” way. My layman’s interpretation of the idea is that instead of threating punishment and setting up rules, you try to encourage desired behavior with rewards and discourage undesired behavior by making it require an effort. When working with the new Test Runner view in the Simics 4.8 GUI, I realized that we had invented exactly such a nudge.

Wind River Blog: Collaborating with Recording Checkpoints

There is a new post at my Wind River blog, about how some new features in Simics 4.8 improve the collaboration power of Simics checkpoints. For the first time, Simics checkpoint can now carry a piece of history (slice of time), which also makes reverse execution and reverse debug work with checkpoints in a logical way.

Wind River Blog: Simics 4.8 is Here

Simics 4.8 is finally released, and I put up a blog post explaining the most important news in this release. It is two years since we released Simics 4.6, so there is quite a bit of news in Simics 4.8 – even though lots of functionality has been released continuously into 4.6 over the past twenty four months. My personal favorite are the comments you can put on an execution and the stop log,  but then again, that might be because they have been a couple of pet ideas of mine so I am hardly an impartial judge. Everything else is also really good, and the engineering teams and marketing teams involved have put in a lot of effort into this release (as we do in all releases).


A Few Electrons too Many

Adding electronics to systems that used to be mechanical has been the great wave of innovation for a quite a while now. Modern transportation just would not work without all the electronics and computers inside (someone once quipped that a modern fighter is just a plastic airplane full of software), and so much convenience has been provided by automation and smarts driven by electronics. However, this also introduces brand new ways that things can break, and sometimes I wonder if we really are not setting ourselves up for major problems when the electrons stop flowing.
