Outreachy poster

Debian is participating in the 13th Round of Outreachy.


Debian has been encouraging women to increase their engagement in the free software community for many years. We strongly believe this is a win-win situation for women (who open up new opportunities for themselves through community networking) and the wider free software movement (who benefit from the untapped potential of talented female developers). Statistics show that although we have increased the number of women participants, we still have plenty of room to grow. With this initiative we hope more women will see opportunities to become involved in the Debian project.

Thanks to the efforts of the program organizers, Outreachy has now been expanded to other underrepresented groups in the Free Software community, which is perfectly in line with Debian's Diversity Statement

Clean Room for PGP and X.509 (PKI) Key Management

Description of the project: PGP is an important technology for a distributed online community like Debian. The PGP Clean Room aims to make it easier for new and existing participants to create and manage their PGP keys in a secure manner. An intern working on this project can focus on documenting the workflow, developing helper scripts to manage the filesystems for private key storage and developing a text-based UI using Newt (python-newt is preferred). Please also see Daniel's blog for the current status of this project.

  • Confirmed Mentor: Daniel Pocock

  • How to contact the mentor: use the pki-clean-room mailing list to introduce yourself

  • Confirmed co-mentors:

  • Deliverables of the project: making scripts and documents for the clean room project

  • Desirable skills: Python, Newt, PGP, X.509, Cryptography, Shell scripting, User interface design

  • What the intern will learn: Python, Newt, PGP, X.509, Cryptography, Shell scripting, User interface design

  • Related projects: GnuPG

Improving voice, video and chat communication with free software

Description of the project: have a look through the projects completed during GSoC 2016, extending any of these projects would be possible. Also look at the project ideas at Filter the list using the tags for programming languages you are most familiar with (for example, C, C++, Python, Java, PHP). In your application, specify which of the ideas you would like to work on. Some of these are only small projects and you will need to propose doing more than one of them during the internship. When thinking about which task you would like to work on, it is important to think about how it will be used by the Debian community and mention this in your application.

  • How to contact the mentor: join the Free RTC mailing list and send a message introducing yourself. Put [Outreachy] in the subject line of your message.

  • Confirmed co-mentors: Daniel Pocock

    • Do you know anybody who is willing to be part of the mentoring team? If so, please ask them to contact me.
  • Deliverables of the project: completing one or more of the issues in

  • Desirable skills: At least one of C, C++, Java, Python, ?JavaScript

  • What the intern will learn: helping people to avoid using proprietary communications tools like Skype, Viber and ?WhatsApp. Learning about SIP, XMPP and peer-to-peer technology.

  • Related projects: see the projects completed during GSoC 2016 for ideas.

Reproducible builds for Debian and free software

Description of the project: We want to provide Debian users with a verifiable path between the binaries we ship and their source code. With “reproducible builds” independent parties should be able to create byte-for-byte identical packages from the same source. ReproducibleBuilds are about trust, quality assurance, and having free software up to its promises. Good progress has been made over the course of the past year, but a good amount of work remain on individual packages, toolchain issues, infrastructure, debugging tools, and documentation.

  • Confirmed Mentor: Mattia Rizzolo

  • How to contact the mentor:, mapreri on IRC.

  • Confirmed co-mentors: Holger Levsen (h01ger), Reiner Herrmann (deki), Chris Lamb (lamby), Ximin Luo (infinity0)

  • There is room for more than one intern, probably we can mentor up to three people, as there are small and bigger tasks to work on:

    • (!) Improve test and debugging tools:

    • (!) Improving reproducibility of Debian packages:

      • Analyzing why packages are not reproducible.

      • Fixes for identified issues: both their root cause and easy to use work-arounds; we recently identified a new source of randomness (build-path variations) and that will require quite some work on several toolchain packages

      • Patches for individual Debian packages.
    • (!) Improving Debian infrastructure:

    • (!) Help collaboration accross distributions

      • Design and implement a shared database for package status and common issues.

  • Desirable skills: We are a diverse team, ready to help with knowledge in many different areas. The following list of skills is both incomplete and too long, but anyway, useful skills are:

    • To improve Debian packages: basic understanding of how packages are made, a thrill for investigations, a taste for fun hacks.
    • Python for diffoscope.
    • Perl for strip-nondeterminism.
    • Shell and Python for
    • Web design to enhance
    • Basic web editing (Markdown, HTML) for documentation.
  • What the intern will learn:

    • A lot about the many different ways software can be built.
    • How to make build systems reproducible.
    • Many details (that you might regret learning) about how our plumbing tools work.
    • How to interact with other Debian developers and research suitable solutions with them.
    • How to design easy-to-use development tools.
