comment Ubuntu not balancing cpu usage among cores, making load go up
A number please, @Bob, not a link to how load is calculated. What is the load number on your 8-logical-cpu box? Is it over 8.0? If not, you can completely stop worrying the issue at all. I'm just asking low hanging fruit, as there still seem to be too many people that think load > 1.0 is a problem when it's really load > cpu-count that signals overload (more runnable processors than a resource to run them on).

because the scheduler thinks it has better things to run on that core. When you say your load average is high, what values are you actually talking about?

They don't just share cache, they share execution units and some TLBs.

An i7-920 has only four physical cores, BTW; SMT presents 8 logical cores, but pairs of those logical cores run on the same physical core.

comment How can I get OS/X-like switch windows of same program bound to hotkey with linux GUIs?
Last time I gave it a try, Gnome 3 made me sad (but I'm glad they at least got this nice feature right)

comment Downloading only images using curl or wget?
Ah, I didn't realize you had files saved with wrong extension problem too. I would have suggested file --mime to map the appropriate real extension too.
