fuse.gunzip is a filesystem for FUSE that provides transparent decompression of files. The goal is to expedite reading of files by reducing both file size and fragmentation. fuse.gunzip is not a real filesystem such as ext2 or ext3. fuse.gunzip is a virtual proxy filesystem. Compressed files appear as uncompressed when read by the kernel or processes through fuse.gunzip. Any type of file can be compressed.
fuse1.pl is a nontrivial demonstration of Fuse.pm, the Perl language interface of FUSE, the Linux userland filesystem. fuse1.pl reflects a subpath of the host filesystem as a mount point of type fuse. Read-only and read-write mounts are both possible. All Unix filesystem operations are supported, except for the handling of POSIX extended attributes. Large files (i.e. files longer than 2GB) are not supported.
OpenDocument Viewer is a cross-platform viewer for OpenDocument files. It supports text documents, spreadsheets, and presentations. Support for drawings and spreadsheet charts is planned for a future release. The viewer supports most of the features that you would expect in a complete ODF viewer. It supports standard navigation features like search, standard viewing features like paged view, print preview, and changing the text size, and document properties like word count.
The i2c-tiny-usb is a open source/open hardware project. It is meant to replace those i2c printer port interfaces often used to connect i2c sensor chips (e.g. temperature sensors) to a Linux PC. It is fully documented and based on cheap and easy to obtain hardware. It comes with a Linux kernel driver, and can thus re-use existing Linux i2c client chip drivers. It additionally comes with a libusb-based demo application that also works under Windows and Mac OS.
movemetafs is a searchable filesystem metadata store for Linux that lets users tag local files (including image, video, audio, and text files) by simply moving the files to a special folder using any file manager. It also lets users find files by tags using a boolean search query. The original files (and their names) are kept intact. movemetafs doesn't have its own user interface, but it is usable with any file manager.
elfrc is a program which can turn arbitrary files into ELF object files which can then be linked into your program directly and accessed via simple, user-defined symbol names. Since this is much more effective than turning a binary file into a C array and then compiling that, it's possible to embed even huge (a few hundred megabytes) files directly into the executable and then access the data in constant time without making the compiler or linker eat loads of memory.
