State of the Commons


Creative Commons has published an infographic, called State of the Commons, illustrating the extent of CC licensing in 2014. According to them, the number of Creative Commons licensed works is approaching one billion. The most common license in use is Creative Commons Attribution-Share Alike, the one I’ve used for Green Comet. CC-BY-SA is the third most open license, and the least open to still be called a Free Culture license.


This is encouraging news.. I’m glad to be part of it.

Cloud of the Day – Fractus

Fractus are subsidiary clouds, also referred to as accessory clouds. This means that they are associated with primary clouds such as cumulus or stratus. That’s why fractus clouds are always named in combination with the cloud type that they are accessory to. When associated with cumulus they’re called cumulus fractus, with stratus, stratus fractus.

They’re called fractus because they have a ragged or shredded appearance. Cumulus fractus, for instance, looks like a nice, puffy cumulus cloud that has been torn up. Stratus fractus looks as if it’s been torn off the bottom of a layer of stratus cloud. Fractus clouds that form under the main cloud are often seen moving in a direction different from the overall movement. This can indicate what the wind is doing there and, if the speeds and directions differ significantly, can show instability and wind shear. This can be useful to pilots, who tend to call it scud cloud, for the way it scuds along. There’s also an acronym: scattered cloud under deck.

Fractus clouds are good weather indicators. They often form under rain clouds, including cumulonimbus, and at the leading and trailing edges of weather fronts. If the stormy weather hasn’t struck yet, fractus can be a sign that it soon might.

No precipitation comes from the fractus itself, but may come from its parent cloud.
