loggerfs is a FUSE-based virtual file system that automatically parses log files and sends that information to a MySQL or PostgreSQL database. Existing log parsers usually run periodically and scan the entire file for changes. loggerfs takes a different approach by providing a virtual file system. Whenever data is appended to a virtual file by the logging daemon, the information is directly stored in the database. There is no need to poll the file and monitor for changes.
Ceph is a distributed network file system designed to provide excellent performance, reliability, and scalability (from terabytes to exabytes). Data is stored in the form of "objects" (variable length, named chunks of data) in a distributed and fault tolerant cluster of OSDs (object storage devices--servers running the Ceph OSD daemon). Metadata (the file system namespace) is managed by an independent cluster of metadata servers (MDSs), which dynamically repartitions the directory hierarchy in response to the current workload.
romfser is userland program for listing, extracting, and partially mangling romfs images. You can provide it with an offset in an image where the file system starts. The mangling ability is expressed in file substitution, where the new file has to be equal or smaller in size compared to the file being replaced. It can extract single files into the current directory or extract the whole filesystem while preserving the directory structure.
PySamba is a Python library that provides a full wrapper for the Samba CLI library provided with samba-3.0.24. It includes a Python module that hides the complexity of the lower layer (SMB), providing high-level commands like Mkdir or DiskAvail. PySamba allows the developer to interface to any samba-capable device much like Python's ftplib does.
JIIC is a streaming-based Java implementation of ISO 9660 for creating CD-ROM filesystem images ("ISO images") with the extensions El Torito, Joliet, and Rock Ridge. It is based on the SABRE streaming API, and provides an Ant task for easy integration into Java-based build processes.
