Regularly, we at OStatic update our collections of open source resources, tutorials, free open source books, reviews, product comparisons and project tours. These educational toolkits are an essential part of the learning mission we try to preserve at the site. Whether you’re looking for resources for working with and enjoying online video and audio, Linux tutorials, offbeat open source applications, or other items of interest, we have useful collections of resources on this site. Outside of OStatic, there are also many useful open source roundups. In this post, you’ll find our latest roundup of the most useful open source guides and tools, including both internal and external posts.
