Big Fraction is a Java class that represents an immutable fraction, as held in a numerator and denominator. Calculations may be performed on this fraction, but the value is always held as a numerator/denominator pair. Therefore, no precision is lost. The fraction may be top-heavy, but is reduced when printed. The value can be converted into floats if desired, although precision will invariably be lost, and some large fractions (such as calculations for pi) can not be converted if the values of BigInteger exceed the range capable of floats.
gccwrap 32bit is a set of simple wrapper scripts to make it easy to compile 32-bit only programs with uncooperative Makefiles on 64-bit systems. You can just use "32bit make" to compile them and the wrappers will transparently add any -m32 options needed and also do some other transparent fixups. This package requires a Linux distribution with proper FHS compliant -m32 / multilib support like SUSE, Fedora, or Mandriva.

slapi-dnsnotify is a plugin for OpenLDAP or other LDAP servers. It watches for changes in the serial number of a DNS zone stored in the LDAP server, and notifies DNS slave servers to refresh their copy of the zone. It can also increment the serial number of a zone whenever changes in that zone are made.
