pg_repack is a PostgreSQL extension which lets you remove bloat from tables and indexes, and optionally restore the physical order of clustered indexes. Unlike CLUSTER and VACUUM FULL, it works online, without holding an exclusive lock on the processed tables during processing. pg_repack is efficient, with performance comparable to using CLUSTER directly.
EXIP provides a C library for the parsing and serialization of Efficient XML Interchange (EXI) format streams. The focus is portability and efficiency for embedded systems development. The project was started at the EISLAB research group in the Department of Computer Science, Electrical and Space Engineering, Luleå University of Technology, and is part of research efforts to bring resource-constrained embedded devices, such as wireless sensor nodes, closer to the enterprise business processes taking place in processing, manufacturing, and communication industries.
Changing directories in bash can be tedious if you have long names or nested paths. Creating aliases or adding to the CDPATH can help, but can be improved on. Bashcd adds 6 new commands to make changing directories a bit easier. This commands use find, the locate database, the mdfind database, or other contextual information to make it easier to change to other directories.
