pgnotifyd connects to a PostgreSQL database, listening for the named asynchronous notification. When notification is received, it executes the given command. It can work as a drop-in replacement for polling a PostgreSQL database for changes (e.g., using crontab(5)), and is typically a cleaner and more efficient alternative.
SafePatch lets you edit program files and track those changes creating "patches" which can later be reverted or reused in a different setup. It's written in PHP, but can patch non-PHP applications because no integration into their source code is required. A bundled Control Panel allows easy tracking, installing, reverting, and diffing of available patches. SafePatch has an intuitive text patch file syntax which is uniform for text and binary files and independent of the engine being patched, has default support for VQMod .xml patches and FluxBB README mods, is written in OOP and uses events (and thus is easily extensible), and doesn't need a database.
SearchBin is a fast commandline program for searching within binary files. It's a bit like grep for binaries. It offers wildcard matching and has three capabilities for searching: for bytes using hexidecimal, for a plain text string, and for a smaller binary file. Any discovered matches will print the found offsets (0-based).
Ramona is an enterprise-grade runtime supervisor that allows software programs to be controlled and monitored during their execution life cycle. It provides supervisor/console functionality with init.d-like start/stop control, continuous integration (e.g. unit/functional/performance test launcher), deployment automation, and other command-line oriented features.
Fluxfont is a specialized tool that attempts to tackle the privacy concerns raised by the possibility to collect information about the fonts installed on a system. Such information can be used to uniquely identify a system. With Fluxfonts, new fonts are randomly created and removed to prevent the same fingerprint from being recreated.
