Here we have a couple CCTV lenses using the C-Mount 'standard': Computar 12.5mm F1.3 and Canon 12.5-75mm F1.8. Even though both are made for 1" or 2/3" (respectively) format video camera, they can be used on Micro 4/3 camera, such as an Olympus E-PL1, via an adapter. Aside from being bright and fairly wide, both lenses vignette quite a bit.
Cameras such as the GF1 and E-PL1 from Panasonic and Olympus, respectively, are using the new Micro 4/3 format standard, which is a type of Electronic Viewfinder, Interchangeable Lens (EVIL) camera. Despite the dubious acronym, the "EVIL" concept is intriguing as it provides DSLR image quality in a smaller, prosumer point-n-shoot like body accomplished by removing the mirror box and optical viewfinder. A side effect of this is a reduction in the flange focal distance (aka flange-to-film distance or back-of-the-lens-to-film/sensor distance in layman's term), which allows the "EVIL" camera to accept and (manually) focus almost any mass-produced lens via adapters. This means, you can use your daddy's film camera lenses on your brand spanking new Olympus E-PL1 or the soon-to-be available Sony NEX3/5.
Web services outputting JSON has become quite common these days; however, consuming such delicious data was not possible purely in JavaScipt because of the same origin/domain policy. Not anymore. As of jQuery 1.2, loading JSON from a different domain is possible.

Attaining performance and scalability in a large Drupal site requires a good amount of time and effort. In addition, speed gains become smaller and smaller after more and more work is spent. Eventually, the exercise becomes futile.
On the other end of this optimization, you can do a few things to a small Drupal site from nothing at all and considerably decrease load times; also, (almost) no coding is required.
Here are a handful suggestions that will help almost any Drupal site and they are easy to do.
