  1. If you aren't yet using Puppet or Chef for managing your *nix infrastructure, you should seriously consider it. The benefits are enormous. Frankly, I don't think you __can__ manage a modern infrastructure without using Puppet, Chef, or reinventing a configuration management framework with your own custom scripts. However, you can't use both Chef and Puppet together, so which should you choose?

  2. Blueprint reverse engineers servers Easy configuration management. Detect relevant packages, files, and source installs. Generate reusable server configs. Convert blueprints to Puppet or Chef. No DSLs, no extra servers, no workflow changes. Blueprint looks inside popular package managers, finds changes you made to configuration files, and archives software you built from source. It runs on Debian and RPM based distros with Python >= 2.6.

It's an easy step to take, and it means that users of HSTS-compliant browsers (such as Chromium and the upcoming Firefox 4) or browsers with HSTS-compliant extensions (like Firefox's NoScript or HTTPS-Everywhere) will no longer be vulnerable to attacks like sslstrip once they have made one successful connection to the HSTS-enabled HTTPS web site.
