DAViCal is a server implementation of the CalDAV protocol for storing calendaring resources (in iCalendar format) on a remote shared server. An increasing number of calendar clients support the maintenance of shared remote calendars through CalDAV including Mozilla Calendar (Sunbird/Lightning), Evolution, Mulberry, Chandler, and various other closed-source products such as Apple's iCal and iPhone. DAViCal supports basic delegation of read/write access among calendar users, multiple users or clients reading and writing the same calendar entries over time, and scheduling of meetings with free/busy time displayed.
CUON is an ERP system with a powerful document management system. The server runs on Linux systems. The client works on Linux, Windows, and some small PDAs like the Nokia N800. You can manage addresses, articles, projects, and so on. On some installations, more than 1,000,000 adresses are supported. CUON has its own report server to build documents and reports and a Web server for iCal and scheduling.
Email-reminder allows users to define events that they want to be reminded of by email. Possible events include birthdays, anniversaries, weekly, monthly, and yearly events. Reminders can be sent on the day of the event and a few days beforehand. It uses a cron job to checks for events and send reminders once a day, and a simple GUI that allows users to edit the reminders they want to receive.
pin 'em up is a tool for placing small notes/post-its (e.g. TODOs/reminders) on your desktop and organizing them in various ways (categorize, hide, upload, export, etc.). Due to platform independence, the notes can also be shared on different operating systems. It features system tray integration, freely placeable notes, many possibilities to customize the note design, (nearly) unlimited user-defined categories, fast switching between categories (e.g. "home" and "office"), automatically saving notes to a file, an open file format (XML), server upload/download functions (FTP and WebDAV), and exporting notes to a text file.
METSlib is an object-oriented metaheuristics framework in C++ designed to make implementing or adapting models easy. The model is modular: all the implemented search algorithms can be applied to the same model. METSlib implements the basics of some metaheuristics algorithms, such as Random Restart Local Search, Variable Neighborhood Search, Iterated Local Search, Simulated Annealing, and Tabu Search. For each algorithm, you must implement an objective function, a neighborhood (move manager), and some moves. Tabu Search is one of the fastest ways to generate near-optimal solutions to a wide range of hard combinatorial optimization problems.
RDVz is a Web application for setting conveniences for meeting appointments between several persons. RDVz uses a poll system: each invited user votes for one of the dates suggested by the meeting organizer. The poll organizer chooses possible dates, creates the poll, and sends the poll's URL to the participants. The organizer can export poll results in a CSV file. Anonymous access, MySQL, LDAP, and SSO (CAS) authentication methods are available.
