On a regular basis, we at OStatic round up our collections of open source resources, tutorials, reviews and project tours. These educational toolkits are a big part of the learning mission we try to preserve at the site. We regularly collect the best Firefox extensions, free online books on open source topics, free tools for developers, resources for working with and enjoying online video and audio, Linux tutorials, and much more. In this post, you'll find an updated set of more than 50 useful open source resources. Hopefully, you'll find something to learn from here, and the good news is that everything found in this post is free.

Here at OStatic, we regularly round up educational posts and new ideas for users of open source. Collections of open source tools, some compiled by us and some compiled by others, can take you in new directions and make you more productive. Here, below the fold, are 8 useful collections of open source tools and tips to try.

Often, when I hear from OStatic readers, they express interest in open source graphics tools. Many of them already use some of the best tools, but there are actually many, many good, free resources in the open source arena for adding to your graphics arsenal. There are also free tutorial resources for getting started with them right away. Whether you want to produce a full-length animated movie, desktop publish good-looking graphical booklets, add a "galactic" brush set to GIMP (for effects like the one at left), work more efficiently with Flickr, or create eye-catching logos, check out our updated collection of 12 free graphics applications and resources here.
