Part of our expertise stems from having been directly involved in the evolution of the open source ecosystem we serve. Our contributions have in fact enabled us to obtain an insider perspective into the potential, evolution, social dynamics and, in some cases, limitations of open source software and an open development model. We take great pride in even our most basic contributions as they have given us the opportunity to weave part of the immense fabric that is the open source software world.

Here you will find links to our most prominent contributions. Some of these have long been absorbed or superseded by other projects which built on our work, yet others are still timely and current and are actively used or referenced. We encourage you to explore the links below and use and/or participate in projects that you may find of interest.

Recent Open Source Projects

Teambox - A file-sharing and sync'ing solution.
echotracker - An Outlook-integrated social aggregator based on .NET's WebBrowser object and written in C#, CSS, HTML, JavaScript, and jQuery.

Legacy Open Source Projects

Linux Trace Toolkit - The first ever Linux tracing suite. Released by Opersys 1999 and maintained through 2005, LTT has since seen the emergence of several other tracing mechanisms and tools for Linux, including its successor LTTng maintained today by EfficiOS.
relayfs - A high-speed data relay filesystem for transferring very large amounts of data from the kernel to user-space with little to no impact. Relayfs has been merged into the mainline kernel and is now found in kernel/relay.c.
Adeos - We introduced the design behind the Adaptive Domain Environment for Operating System in 2001 as a mechanism for allowing several operating systems to share hardware resources. Philippe Gerum (of Xenomai fame) later implemented the first version of Adeos and its successor, the i-pipe. Adeos is presently maintained on Gna!.
LRTBF - The Linux Real-Time Benchmarking Framework was introduced in 2005 to help study the latency differences between the i-pipe and the PREEMPT_RT patch-sets. LRTBF-generated results were posted onto the kernel development mailing list and helped both projects and outside observers get a better grasp of the potential and pitfalls of each approach. The LRTBF is no longer maintained.
Osiris - Osiris was a distributed microkernel proof-of-concept implementation that preceded our work on LTT and helped us develop the methods that later enabled us to design and implement LTT. Osiris is no longer maintained.
