You can help two birds with one donation this holiday season. The Linux Foundation, the non-profit organization dedicated to accelerating the growth of Linux and other open-source collaborative development projects such as OpenDaylight , announced its 2013 Holiday Individual Membership Drive. In it, the group will donate $25 to the World Wildlife Fund for emperor penguins for every new member who joins, today through 11:59 PM. PT on December 10, 2013.

Loyal Linux users will know that the connection between an operating system and a flightless water fowl is that a penguin called Tux is widely known as the Linux mascot.

So, if you want to help advance the Linux operating system and support the work of Linux creator Linus Torvalds, you can join nearly 10,000 developers from more than 1,000 companies who build Linux every day. For annual membership fee of $99, $25 for students, you'll receive exclusive benefits that include a Linux.com email address (e.g. john@linux.com); employee purchase pricing from Dell, HP and Lenovo; up to 40 percent off O’Reilly books and e-books; and a variety of other discounts to attend events, take training and subscribe to industry publications.

You'll also be helping emperor penguins. Climate change and habitat loss are posing great risks for these animals.
