NVIDIA Shows Off "Optimus" Switchable Graphics For Notebooks 102

Vigile writes "Transformers jokes aside, NVIDIA's newest technology offering hopes to radically change the way notebook computers are built and how customers use them. The promise of both extended battery life and high performance mobile computing has seemed like a pipe dream, and even the most recent updates to 'switchable graphics' left much to be desired in terms of the user experience. Having both an integrated and discrete graphics chip in your notebook does little good if you never switch between the two. Optimus allows the system to seamlessly and instantly change between IGP and discrete NVIDIA GPUs based on the task being run, including games, GPU encoding or Flash video playback. Using new software and hardware technology, notebooks using Optimus can power on and pass control to the GPU in a matter of 300ms and power both the GPU and PCIe lanes completely off when not in use. This can be done without being forced to reboot or even close out your applications, making it a hands-free solution for the customer."

I am currently working on automated GUI tests for an application, and Sikuli looks pretty great -- even when compared to enterprise level automated GUI testing tools costing in the order of thousands of dollars per user licence.

Some of the commenting below on maintainability problems seem pretty superficial. For example, to ease maintainability you could build a framework abstracting GUI component images from regression test scripts. For example, you could assign a screenshot as a variable and then refer to that variable throughout your test, so if a button happens to change dramatically, you make the change in potentially one place in your code instead of every time it is used in a click. The fact that the tool appears simple (not too many bells and whistles) and is based on Python seems to be major advantages for maintainability.

Check out this interesting academic paper which specifically addresses using Sikuli for automated GUI testing: "GUI Testing Using Computer Vision, CHI 2010" at

Has anybody actually used Sikuli? I'd be very curious if anybody has used this for automated GUI testing in a corporate environment...
