Thumbpad is a simple note taking program, which displays a very large keyboard that you can easily type on using only one finger. So, if you're holding your PDA with one hand, you can use your thumb. The default keyboard provides the 16 most commonly used keys (in English), and two other layouts provide the remaining letters, numbers, and some punctuation. Thumbpad is an FLTK application, originally intended for the Agenda VR3 PDA. It is based on utilware's "dotNote" for PalmOS.
npadmin is a command line tool to administer network printers. It is based on the concepts of JetAdmin and other vendor's tools but is designed to be scriptable. It uses SNMP to query the common printer MIB (RFC 1759) and return information about the printer. There is a surprising amount of information available in the common printer MIB and since the vendors all use their private MIBs, this appears to be the only tool that makes it available.
