Debian is among the oldest GNU/Linux distributions still active today. A community-led project with democratically elected leadership, Debian remains a shining example of a project that serves developers and users rather than for profit interests and wealthy trade associations that so commonly control and manipulate Open Source projects today. Debian culture embodies the ethos of software freedom and the tradition of enthusiasts and hobbyists (rather than businesses) directing the future of Free Software projects. As an independent observer and Debian user, in this keynote, I will examine the reasons why these principles have served Debian well, considered early decisions that Debian made that have assured a commitment to principle, explore how Debian can continue to help everyone, introduce future collaborations that might succeed in helping Debian in its goals, and discuss the unique role Debian can play in advancing software freedom.

This talk will discuss two contests with two issues. First contest: Inveneo, LeMaker and ARM have sponsored a contest to develop a solar-powered, highly available, scalable, passively cooled "Micro Data Center" for developing countries. The first part of the contest was to develop a design for the hardware that would use up to 15 ARM-based Single Board Computers (SBCs) and up to ten SSDs with a 16-port Gbit data switch that could be powered by a Solar Panel or other 12 volt supply. Over fifty entries were submitted to a contest ending June 10th, with the results being announced July 20th. Some number of the winning Micro Data Center designs will be built by a company called ProCase. Then a second part of the contest will be to create and configure the software to run these data centers in a secure, highly available, easily updated fashion. The speaker would like the Debian community, spear-headed by Debian developers at Debconf, to create such a package of software. Second Contest: Linaro, a non-profit organization trying to help companies put GNU/Linux on their ARM processors and SoCs, has noticed about 1400 programs in GNU/Linux that still have assembly language in them. This assembly language has often been there a long time, and may (in the days of multi-core, multi-pipelined, multi-level cache) cause the programs to run slower and less efficiently, not faster. Examples of these performance and efficiency issues will be briefly given in the talks. Linaro has designed a contest to port these 1400 programs to ARM-64, and at the same time test to see if the programs efficiency can be improved by recoding the assembly language sections. These contests will be discussed in the talk, perhaps with workshops set up to help address them at Debconf.

dgit is a tool which allows you to dgit clone any package in Debian, and get a git tree. You can work on the package in git, and when you are ready do dgit build and dgit push to upload. Other dgit users see your git history. dgit is particularly useful for NMUers and downstreams.

With free software, anyone can inspect the source code for malicious flaws. But Debian provide binary packages to its users. The idea of “deterministic” or “reproducible” builds is to empower anyone to verify that no flaws have been introduced during the build process by reproducing byte-for-byte identical binary packages from a given source. This talk will explain the current status of the Debian Reproducible Builds project, how this is relevant for the complete free software eco system and how you can contribute.
