Welcome to OSDev.org, the largest online community of operating system developers. If you want to learn how to write your own OS we have all the information to get you started. Read our OS development wiki to learn where to start. The forums are a great place to discuss OS theory and ask for help when you get stuck. Don't forget to add a link on the OS List to your OS project once it gets going.
The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. At present, it provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
1T3XT offers a suite of products that are useful to create and/or manipulate documents, more specifically PDF and RTF documents. There's some support for XML and HTML, but this isn't the core business of iText.
