PM Report is a PHP/MySQL report generator. It creates customizable reports and is very simple to setup and use. You can select which database, table, and individual fields to use on your report. You can also select the order in which the fields should appear on the report, the field you would like to group by, the field you would like to sort by, and whether or not you would like a total for each column. Once the report has been generated, you can highlight individual rows and export the results to CSV.
radlib is a C language library developed to abstract details of interprocess communications and common Linux/Unix system facilities so that application developers can concentrate on application solutions. It encourages developers to use a proven paradigm of event-driven, asynchronous design. By abstracting interprocess messaging, events, timers, and any I/O device that can be represented as a file descriptor, radlib simplifies the implementation of multi-purpose processes, as well as multi-process applications. In short, radlib is a sincere attempt to provide real-time OS capability on a non-real-time OS.
