Oww (One-Wire Weather) is a client program for Dallas Semiconductor / AAG 1-wire weather station kits, providing a graphical (animated) display to monitor outside temperature, wind speed and direction, rainfall, and humidity. Extra temperature sensors may be added. A 1-wire "hub" may be used for improved reliability and range. Weather data may be logged to CSV files, parsed to command line programs, sent to the Henriksen Windows client, or uploaded to Web servers at Dallas, The Weather Underground, and HAMweather.
Oberon2 is a simple and safe object-oriented language created by N.Wirth, the author of Pascal and Modula2. It is statically strongly typed and has garbage collection. Most of good ideas incorporated in design of Java were in Oberon2 long before. OOC is an open source project to produce a family of optimizing Oberon2 compilers. The compiler with an ANSI C back-end, oo2c, is quite mature, and provides a complete and convenient Oberon2 development environment. It comes with a rather comprehensive standard library, Code Navigator, and an Emacs mode. It is easy to call C functions and libraries from Oberon2.
Open Cubic Player is a music player which can play a wide variety of music formats. Currently it can play so called modules (MOD, XM, S3M, IT), MIDI, MP1-3, SID tunes, and CD audio. It supports many soundcards (SB, GUS, EWS, WSS, PAS, and many more). It features many different display modes for "looking" (text and graphics) at the music.
OIO is a Web-based metadata/data management front-end which is built using Zope and works with Postgresql. No programming is required to build and manage Web-forms or to perform data mining/analysis on the collected data. It is in production at the Harbor/UCLA Medical Center for clinical outcomes management and research data. Forms created with OIO and hosted on any OIO server can be downloaded as XML files. Once downloaded from the "Forms library" and imported into an OIO server, the necessary database tables are automatically recreated and the imported forms become immediately available to the users of that OIO server.
OMMS is the Open Modular Message System. It uses plugins to support different kinds of message types (mail, news, SMS, ICQ, FAX, voice, etc.), different ways of storing/retrieving the messages (mbox, POP3, IMAP, database, etc.) and many filters to handle messages (send, sort to folders, encrypt/sign, etc.).
Open Motif Everywhere is the standard distribution of Open Motif built from the official Open Group sources for Open Motif. It has been ported to all popular Linux (and BSD) environments. Most modern distributions of Linux and BSD include the stable release. Annual support contracts are also available.
