What happened to "Don't be evil?". Or they changed it to "Do not eval?":D. Bit off topic, but that guy experienced lagginess in UI due some rogue Chrome process. I remember some bug in VLC that slow down my computer to level, it was not even possible to type on keyboard. And I wonder, why is this happening in era of multicore CPUs? Why there is no restriction (by default) for process, how many cores it can utilise? I mean the tooling is already there (cgroups on Linux), but they're not used by default.
