Windows 8+ feature, see reply to kbenson above.

It's a new feature with windows 8[1]. Unofficially you can install windows 7 using the OEM key (note this is not the key printed on the sticker on your laptop) and then activate it.

Thanks. For reference, the use case is to distribute SSL negotiation without losing access to client IP addresses.

Anyone know if the nginx TCP load balancing supports the PROXY protocol? Doesn't appear to, which is unfortunate.

If you don't mind building your own package, this has worked well for us: https://github.com/yaoweibin/nginx_upstream_check_module

Though I agree it'd be nice to have the functionality integrated.

It looks like it still loads the ixgbevf driver:

  # ethtool -i eth0
  driver: ixgbevf

smwht | 11 years ago | on: Amazon’s New Cloud Prices Show That Google Is Now a Threat

If this is Amazon trying to compete with Google's pricing scheme, they missed. Google's sustained use discounts just happen, and give you a discount on whatever time you used. With Amazon's new pricing for reserved instances, any reserved instance you buy (upfront fee or not) commits you to pay an hourly fee regardless of whether the instance is running now.

They removed the light/medium reserved instance options where you paid a discounted usage rate, and now just have 3 ways of purchasing a heavy reserved instance.

This is going to raise prices for us on AWS because we won't be able to use reservations for the instances we autoscale so the current medium reservations we have are going to be on-demand now.

The important character here is the '>'. This redirects output to a file and overwrites the file. The lrwxrwxrwx will only print an error, but the redirect to the target executable will erase the target.

For example:

  $ echo "asdf" > foo
  $ cat foo
  asdf
  $ lrwxwrwxrwx 1 root root -> foo
  lrwxrwxrwx: command not found
  $ cat foo
  $

So basically, this zero'd out every executable on the system.
