icli is a command line interface to the Icinga monitoring software. You can use it to list service/host status with many filtering options, schedule rechecks, and acknowledge service problems. Basic support for viewing the command queue and scheduled downtimes is also present. It is largely compatible with Nagios.
raps2 is a simple password safe. You give it a name, a password, and optional metadata, and it will encrypt and store them for you. It uses Eksblowfish for crypto, which offers a configurable key setup time, so you can make it as slow as you want. Each password is saved in a separate file, making it easy to track them in version control.
QuHelp is a command-line program that scans a directory with HTML formatted text files and builds a help site using that directory's content and a template. A default template is included, but any template can be specified. QuHelp adds a nice expandable tree view of the help site's contents, a navigator, permalinks, and other useful stuff for browsing the help site.
bash argsparse is a high-level argument parsing library for bash. Its purpose is to replace the option parsing and usage describing functions commonly rewritten in all scripts. Its features include automatic help message generation, user input checking (type checking, enumerations, etc.), and option properties (mandatory options, option aliases, options excluding each others, etc.). It is implemented for bash version 4. Prior versions of bash will fail at interpreting the code.
hashl creates a database with partial file hashes. It is useful for checking if you already have a copy of files before transferring them over a slow network. It does this by hashing only the first few MiB of every file. This gives it a huge speed advantage at the cost of possible (though pretty improbable) false positives.
slackeria takes a list of projects and checks whether they are present in certain places, such as freshmeat or various distributions. If they are, their version is also reported. This makes it easy to monitor projects and, for example, to notify distributions of updates when they are lagging behind.
Flex Bison C++ Template is a code template that can be used to integrate a Flex scanner and Bison parser pair into a modern C++ program. These two universal tools are very difficult to incorporate into a good C++ design. The template utilizes both Flex and Bison in C++ mode and their output are encapsulated into classes. Thus the lexer and parser become fully reentrant, and multiple distinct lexer-parser pairs can easily be linked into one binary. The code implements a simple infix-notation calculator as an example, which can be used as a starting-point for you to insert your grammar.
