Unfortunately 11.04 has changed that.

@rodrigob Why don't you submit a patch to bash to that effect?

comment How to power off a hard drive to essentially “hot swap”
If the machine isn't designed for hot-swapping then it may not be safe to hot-swap the drive.

comment What is the best hard drive for random-reading small blocks
Although new SSD have TRIM, which should help this problem, by (AFAIK) allowing a background operation to clear up the pages.

comment UDP traversal through router automatically without router port forwarding?
Actually, while a pure NAT device blocks incoming connections by accident (having no-where to send them), many NAT home routers now explicitly claim to be firewalls.

comment Linux: how to explicitly unswap everything possible?
I'd recommend just allowing normal operations to swap in what is actually needed, rather than manually doing anything.

comment Linux: how to explicitly unswap everything possible?
I agree with this answer - you should probably leave normal operations on the machine to swap in what is actually needed.

@Juliano - Hence my last sentence - If you don't actually have enough memory then the OOM killer will get you.

comment Linux: how to explicitly unswap everything possible?
I'm not sure killing swapoff will actually stop the operation. Depends how it's implemented.

comment Linux: how to explicitly unswap everything possible?
I don't think program memory vs. cache is the issue here - I think it's application memory vs. unused memory. And I don't think swappiness will affect that.

comment Linux: how to explicitly unswap everything possible?
I don't think even a swappiness of zero will cause pages that are already swapped to be explicitly brought into main memory?

Also check your host provider - they may have their own time server.

comment Log file permissions in Linux
It sounds like you have a GUI application that starts when the user logs in? Is that the case?

So start the script form root's crontab then. It doesn't have to run from your user account.

comment ffmpeg with php exec disabled?
I doubt it, since it would be blocked for the same reason SYSTEM() and EXEC() are blocked.

comment How can I sort du -h output by size
First it does the normal du - then for each entry it recalculates the size just to print it in human readable form.

And it'll do a huge amount of duplicate counting.
