Idea list for GSoC 2016

Implement Tinykdump

Status: Proposed - draft

Summary of idea: Tinykdump is a minimal daemon to capture kernel-based crash dumping (kdump) memory image to usb storage. Compared to the traditional kdump solution, it is,

* more reliable and scalable
* has smaller memory foot-print
* more friendly to kernel developers 

More information here: https://fedorahosted.org/tinykdump/

Knowledge prerequisite: Python, kernel programming (desired)

Skill level: intermediate (programming)

Contacts: CAI Qian

Mentor(s): CAI Qian

Notes: Rough roadmap:

  • Implement tinykdump daemon to be included in Fedora.
  • Submit kernel patches for reserving kdump memory at run-time for community review and inclusion.
  • Currently, pstore only log kernel messages for panic and Oops. Patches are needed to support logging of kdump kernel and initramfs console output.

Implement MIPS bits to packages

Status: Proposed

Summary of idea: Some packages are missing implementation bits for MIPS architecture. The goal of this project is implementing and posting them upstream.

URL: https://fedoraproject.org/wiki/Architectures/MIPS

Knowledge prerequisite: Packaging, Python, C

Skill level: intermediate

Contacts: Michal Toman

Mentor(s): Michal Toman

Notes: The following packages are in question:

  • java - builds on 32-bit MIPS but does not work, dies with SIGILL
  • redhat-lsb - misses assembly bits for MIPS
  • anaconda/blivet - completely MIPS unaware
  • valgrind - no FPXX support on 32-bit MIPS, builds on mips64el but does not work
  • elfutils - unwinding is not supported on MIPS
  • u-boot - build working MIPS images
  • ... there are more but these are the most painful

This is obviously too much for a single project, we are going to agree on a reasonable subset.

Expected outcome:

  • Better MIPS support in upstream projects and Fedora packages
  • Learn about MIPS architecture
  • Learn to communicate with upstreams

Idea list for Fedora Community Operations and Infrastructure

Fedora Infrastructure Web Application Development: Community Operations (CommOps)

Project IRC Channel Web Page Mentor(s) Notes
Community Operations (CommOps) #fedora-commops CommOps Wiki The rise of DevOps has been swift. Sysadmins are increasingly instrumenting and integrating automated systems to stand up and maintain their infrastructure. This same approach can be taken to support community infrastructure in a distributed and automated fashion, that doesn't force people to choose between using their precious volunteer time to "build things" or "build communities that build things." The community operations team works across numerous technologies, and interest areas in Fedora, including Messaging, Storytelling, Fedora Badges, Fedora Hubs, Wiki, Culture, Metrics, Voting, and other miscellaneous topics. It is important to note that CommOps team members are generalists, and the strengths and interests of individual applicants will determine the precise nature of your work. Enthusiasm for FOSS culture and community organization, and effective communication skills are most important. Specific deliverables can include automated metrics gathering, real-time messaging integration with Fedora hubs, and other big-data analysis and visualization. Tools are primarily written in python, and utilize libraries such as fedmsg, numpy, pandas, pygals, flask, sqlalchemy. We also leverage other web technologies like HTML5 and Javascript, and frameworks such as bootstrap and handlebars to deliver these metrics.

Your internship with this project could also involve any or all of the following:

  • Web testing and bug reporting / triaging
  • Content development and syndication
  • Writing for the web and print
  • Collaboration with Fedora Council and Leadership on Project Objectives and Initiatives
  • Volunteer Coordination and Organizing
  • Campaign development and implementation
  • Advocacy and Messaging

Required:

  • Effective Communication Skills; written and verbal, synchronous and asynchronous.
  • Passion for Free/Open Source Software and Free Culture
  • Self-directed and Curious nature
  • Experience writing for the web (Content only is ok, HTML/CSS even better)
  • Experience publishing and/or syndicating content via Social Media
  • Experience working in teams, or community organizing
  • Basic Web development/design skills

Bonus Skills:

  • Basic multimedia development skills
  • Sysadmin/Devops skills
  • programming/scripting skills

Fedora Infrastructure Web Application Development: Fedora Hubs

Fedora Infrastructure Web Application Development: Fedora Hubs #fedora-hubs

Fedora has been in the process of creating a new web presence for all of the Fedora users, subprojects, and communities. We also plan to integrate some of the features of this system with the prototype of the Fedora Developer Portal, which is targeted at helping general developers use Fedora. While the Hubs project itself is aimed at Fedora contributor circles, the reusable features will allow the Portal to use this work to speak to general developers who may not have an interest in working in the Fedora community, but want to connect with community members for advice, best practices, or to generate interest in their upstream project.

Several of the principal app developers in the Fedora Engineering team will be working together with you on this project during the GSoC term. You'll participate directly with team members daily on core features of Hubs as well as integration with the Portal. This is a great opportunity both for regular mentorship and for being deeply involved in an exciting and fast-moving project with the Fedora team.

Working on this project could involve any of the following:

  • Adding new features to the web frontend
  • Adding new capabilities to the backend
  • Writing and deploying new widgets
  • Triaging and processing new widget ideas submitted by the community at large.
  • Implementing existing (and thoroughly detailed) mockups from previous UI/UX interns and team members.

Skills:

  • HTML/Javascript/CSS
  • Basic Python a plus
  • Bonus: Experience with Bootstrap, jinja templates, Fedmsg, datanommer/grepper, or other fedora infrastructure projects a HUGE plus.

When applying to this project, it may be useful to review the designers' blogs about the projects' design here:

Fedora Infrastructure Web Application Development: Pagure

Project IRC Channel Web Page Mentor(s) Notes
Pagure #fedora-apps Pagure project Pierre-Yves Chibon (pingou) Pagure is a forge written in python and offering the possibility of self-hosting projects while still using the now well-know fork and pull-request contribution model. While being similar to other forge such as GitHub or GitLab it is also pretty different for example it does not namespace projects under usernames with the idea that projects should not belong to a single person but to a community.

Your internship with this project could also involve any or all of the following:

  • Web testing and bug reporting / triaging
  • Content development and syndication
  • Participating in the effort to make of pagure the official front-end to Fedora's packages git repositories (currently being the read-only cgit)
  • Implementing private projects in pagure
  • Figuring out how/if pagure can be a front-end for Fedora's git repo now that they are namespaced (to offer more than just rpms, for example docker containers)

Required:

  • Effective Communication Skills; written and verbal, synchronous and asynchronous.
  • Passion for Free/Open Source Software and Free Culture
  • Self-directed and Curious nature
  • Experience with Flask, javascript and HTML
  • Experience with git
  • Sysadmin/Devops skills

Bonus Skills:

  • Previous experience with Pagure
  • Experience with developing APIs and CLIs using it

Docs

Anerist

Project IRC Channel Web Page Mentor(s) Notes
Docs Project #fedora-docs [17] Zach Oglesby (zoglesby) The Fedora community produces a variety of content suitable for user reference. Members of the Fedora Project produce documentation in a variety of ways - manpages and code comments from developers, system architecture design and best practices reference material from the infra team; application design, interface design, microservices, buildfarms and more. All at work meeting the needs of a transparent organization built on open source technologies and open development practices.

Anerist is intended to consume reference materials, in whatever format they are discovered in, and render them to produce a neatly indexed html site with a common style and theme. To alleviate manual effort in this conversion process, and in the process of 'cycling' translations, the application is event driven, with content regenerated on each change of the sources using CICD technologies. This design relies on modularized conversion tools, which also allows for programmatically generated content and drop-in custom views of technologies or infrastructure.

We need your help to build this framework. You'll use python, bootstrap, buildbot, fedmsg, git, and more.

Your internship with this project could also involve any or all of the following:

  • Exposure to content development workflows.
  • Mentoring from seasoned sysadmins, veteran technical writers, and free software advocates.
  • Learning the Open Source Way, the practice of transparent positive collaboration that forms bedrock of Fedora's Foundations.

Required:

  • general python skills
  • experience with generating and rendering ReStructuredText
  • familiarity with DocBook, or other structured contextual XML.
  • familiarity with Jenkins, buildbot, or similar buildsystems

Bonus Skills:

  • UX Design experience
  • Free software advocacy
  • Extended community participation
  • Ownership of amusing hats

Open Ideas From GSoC 2015
