As largely self-organizing groups, free software projects have always faced unique challenges when they decide to formally incorporate. The choice whether to form a nonprofit or a for-profit carries not only legal but community consequences. Recently, these choices have only become more complex. The IRS is closely scrutinizing the applications of new free software nonprofits applying for tax exemption, and may apply more exclusive criteria to new applications than it has in the past. Recognizing a need, some established nonprofits have begun sponsoring the activity of smaller, unincorporated projects. And several U.S. states have adopted laws authorizing new "hybrid" corporate forms, "benefit corporations" organized for profit but dedicated to the public benefit. This presentation will discuss the changing corporate landscape of free software and discuss how projects should approach these issues when they consider incorporation.
While Wayland offers improved performance and the ability to create interesting new user experiences, the need to support legacy X applications will remain with us for a long time to come. Integrating X applications into the Wayland environment is a key requirement for the successful implementation of many X to Wayland migration plans. This presentation will describe the existing X environment, then describe how X works in Wayland and discuss the performance implications of the transition.

DTrace is a tracing tool that was originally implemented for the Solaris operating system. We now have started the work of porting the tool to Linux. While still a work in progress (at version 0.2 currently), it already implements some of the most important providers that are useful for kernel debugging, such as the syscall provider, the profile provider, and statically defined tracing. The goal of the project is to maintain as much compatibility with the Solaris version as possible, allowing easy migration of existing scripts. The talk will cover some implementation details, and future direction of the work.

UEFI is a cross-vendor industry standard that replaces the traditional BIOS on x86 hardware. It is becoming increasingly popular, and is likely to be near-ubiquitous in new hardware by the end of 2012. The transition isn't transparent - Linux must adapt to the changes. But what does UEFI give us? This presentation will cover the differences between UEFI and BIOS, the advantages that it brings to Linux and the problems posed by certain aspects of the specification, such as secure boot. The presentation will be a fairly high level overview of UEFI, discussing the recent work carried out with Linux to provide high-quality integration and functional advantages. The audience will not need a strong familiarity with the existing PC boot mechanisms or any understanding of kernel code.
