FIM (Fbi IMproved) aims to be a highly customizable and scriptable image viewer targeted at the users who are confortable with software like the Vim text editor or the Mutt mail user agent. It is based on the Fbi image viewer and works in the Linux framebuffer console (it is not an X program). It features the ability to filter the list of images with regular expressions, Vim-like autocommands, command line autocompletion and history, completely customizable key bindings, external/internal scriptability, and much more.
librsb is a library for sparse matrix computations featuring the Recursive Sparse Blocks (RSB) matrix format. This format allows cache-efficient and multithreaded (that is, shared memory parallel) operations on large sparse matrices. The most common operations necessary to iterative solvers are available (matrix-vector multiplication, triangular solution, rows/columns scaling, diagonal extraction/setting, blocks extraction, norm computation, formats conversion). The RSB format is especially well-suited for symmetric and transposed multiplication variants. On these variants, librsb has been found to be faster than Intel MKL's implementation for CSR. Most numerical kernels code is auto-generated, and the supported numerical types can be chosen by the user at buildtime. librsb implements the Sparse BLAS standard, as specified in the BLAS Forum documents.
