5 Out of 11 Crashed Unity In Canonical's Study

dkd903 writes "Today the results of the Default Desktop User Testing for Ubuntu 11.04 was published by Canonical's Rick Spencer. The test was done using 11 participants from different backgrounds to test the new Unity interface that Ubuntu 11.04 will have." Though the Unity interface in the upcoming Ubuntu is a moving target, the bad news from this test is that about half of the testers managed to crash it.

That's not the worst about it

Crashing is not the worst thing about it, but the fact that it is a worse interface than Gnome 2. It's not terrible like Gnome 3, but feels like a step backwards nonetheless.

Ignore crappy blog - link to results

Just ignore the crappy blog link. It's not really helpful at all. Here's a link to the actual results:

Re:Not that surprising, actually

Um, people do kernel programming in virtual machines. And there's plenty of debugging tools around VMs. I know, I write kernel modules.

Also, kernels can mask interrupts and ensure a function is run "single threaded" (no context-switching out), which dramatically reduces the complexity. Not every function is set up like that, many are thread-safe, but drivers are usually written to be uninterrupted and access private memory, so they don't worry about interaction with other cpus/cores/kthreads.

Both are hard, kernel programming is hard, and the massive multi-threading in window managers is hard.
