Want to install apc on CENTOS or RHEL?

I thought I'd put this in as well, since I had to google for it, using -n will make iostat provide you with stats for nfs shares too.
You can also use nfsstatiostat -nh 5
nfsstat -cvn -o nfs

I thought you may like to know (unless I'm the last one to cotton on!) that a scenario we've theorised about on the ASRG mailing list for years is finally here, there's now at least one commercial service that will translate CAPTCHA's for cash.
I found the link (shown below) to a service that will decode captcha's for you for $2 per 1000 successes. (Ironically it was in an ad served to me by gmail.)
So to anyone who ever proposed a spam "solution" that relied on differentiating between people and machines, and doubted us when we told them that the commercial imperative would be its downfall, read this:
We told you so, and it only costs two bucks for a thousand!I predict much more of this in time, with costs falling as more competition enters the market, and I honestly think it presages the end of the useful life of the captcha.
That link: http://www.decaptcher.com/client/
-- correction: Kevin H. politely pointed out, in a comment, that I hadn't read it properly
That isn't $2 per success - it's $2 per 1000 successes. Minimum purchase is $10 = 5,000 spam, er, advertising opportunitiesThanks Kevin, I've updated the post to reflect this.
-- updates: According to ASRG folks
a) This site has been known about since Oct, '09, so yes I am last to the party as ever!
b) Chris Lewis kindly point this out:
... found sweatshops in India quoting some small number of rupees per thousand, claiming to be able to supply up to 250,000 per day. At _least_ three years ago.c) More intriguingly Steve Atkins said:
Incidentally, some of the spam filter companies, as part of their technology for trying to figure out whether the jpeg is naughty or not, _claim_ they can solve >90% of all captchas on the fly.
I found that particularly fascinating, because last year Nikki was telling me all about cognitive psychology and various theories of word and character recognition in humans. I still have all that to look forward to, in my OU degree, but I'm beginning to get an idea of the kind of things I could do for my project if I ever get that far!

This is a useful one if, like us, you find that the account used to create the procedure doesn't have the privileges required to execute it, or perhaps you've revoked the original definers grant. (DoH!)
It seems that the way in which facebook chooses an image to show alongside a posted link differs for links posted in different ways.
Oh how fucking hilarious. Not.
On our product page if you "attach" the link, or share it using facebook sharer (http://www.facebook.com/sharer.php) it picks the big product image as the first image in the list for you to choose from. This is a Good Thing, and exactly what we want to achieve.
However if you click the like button, its picking up a random image from sets of smaller images elsewhere on the page.
e.g. Share this dress' page through the sharer, or by "attaching" and you see this image:
but if you use the like button it shows us this image,
which is for this dress.
Arrgghh that's annoying. Get a damn grip facebook, at the very least you could try to be consistent. Read about the principle of least surprise.

I know nothing, I'm not a fortune teller, and you'd be insane to think that I am. This disclaimer was cribbed from an email footer I once received. It is so ridiculous I had to have it for myself.
