Hodie prints the current date and time to stdout in Roman numerals, with grammatically correct Latin. Complete with Id., Kal., Non., pridie, postridie, bis, and all the other nice annoyances. As an option, it even provides you with current date according to Roman calendar -- that is 'ab urbe condita'; after Rome was built.
The Home Library Information Manager (HLIM) is a utility that allows you to track your home library (books, magazines, and CDs) using either barcode scanners or hand entry. Everyone's favorite feline-shaped scanner is supported, as is manual entry from the keyboard. CD title and track information is automatically looked up from the CD Index (http://www.cdindex.org/). Please note that this is alpha in quality and only supports the PostgreSQL database, although any database with commit/rollback support should easily work. Also, documentation is currently thin.
Hood is a C++ user-level threads library for multiprogrammed, shared-memory multiprocessors. Hood is designed primarily for parallel programs, and it is especially effective for dynamic, highly asynchronous parallelism. Hood's thread scheduler is a non-blocking implementation of the work-stealing algorithm that has been shown to be efficient both in theory and in practice. The current version fully supports Solaris (SPARC) and partially supports Linux: due to the Linux implementation of pthreads, many library calls are not safe for use within Hood threads (this problem does not exist under Solaris).
Hostinfo is a utility for looking up hostnames and IPv4 addresses. Hostinfo uses the gethostbyname(3) and getaddrbyname(3) function calls, which means it tells you what your operating system really thinks rather than simply doing direct DNS lookups. Hostinfo provides options for both displaying and interpreting IP addresses in hexadecimal and backslash-octal notations as well as in the traditional base-10 dotted-quad notation.
HPFind searches your users' directories for homepages and displays them in a table on an html page. All outputted text and background colours, and file locations can be specified by the administrator. It is able to exclude a given list of users. This program can be used as a small search program to search for filenames.
The HTML Pre-Processor is a perl5 script that does basic including, #defines, and assertions for HTML, much like cpp(1) does for .c source files, but it is lacking a lot of cpp's features (and internal complexity). HPP is useful for simple site includes and conditionals on sites that do not have SSI or where its useful to have pages "pre-compiled", and may be useful just to do a unified look n feel throughout your pages.
