Bedework is an open-source enterprise calendar system that supports public, personal, and group calendaring. It is designed to conform to current calendaring standards (iCalendar RFC 2445 iCal, iTIP: RFC 2446, CalDAV: RFC 4791, VVENUE) with a goal of attaining strong interoperability between other calendaring systems and clients (Mozilla Lightning, Apple iCal). Bedework is built with an emphasis on higher education, though it is used by many commercial enterprises. You may choose to deploy Bedework for public events calendaring, personal calendaring and scheduling, or both. It is suitable for embedding in other applications or in portals and has been deployed across a wide range of environments.

dd is a Unix command line utility for copying data. ddpt adds features for efficiently copying large amounts of data to and from disks. Apart from accessing disks using traditional Unix read() and write() calls, ddpt can optionally use SCSI pass-through interfaces to send SCSI commands to perform a copy. In Linux, the pass-through can be used to send TRIM commands to SSDs. It is written for Linux with ports to FreeBSD, Solaris, and Windows.

The Go Programming Language (Go) is an expressive, concise, clean, and efficient language with concurrency mechanisms that make it easy to write programs that get the most out of multicore and networked machines. Its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
