This document outlines Stefano Zacchiroli's presentation on teaching opportunities with Debian. The presentation provides a gentle introduction to Debian, its history and components. It then discusses ways for students to get involved with Debian, such as joining packaging teams, adopting orphaned packages, fixing bugs, and improving infrastructure. The goal is to understand how participation in Debian can contribute to student formation.
Ubuntu Server - A Quick and Comprehensive Overviewevolutionaryit
Have you heard the news? Most everyone knows that Ubuntu is an outstanding desktop but few know of its compelling server option. Join us to find out why Ubuntu Server is a highly affordable, usable, stable and secure platform on which to build just about anything.
Free and Open Source Software has supernumerary security tools/applications can help improve the security stance of the modern enterprise. Learn how nearly every security problem has an many FOSS (Free and Open Source Software) solutions that can help.
Features and Comparison - Ubuntu, Debian, Cent OSShubham Sharma
This presentation deals with the basic LINUX knowledge and studies the distros, Ubuntu, Debian, and CentOS.
Finally, it compares the main differences between them with 6 areas taken in the consideration.

CentOS Virt SIG - Community virtualization packages on an immutable coreThe Linux Foundation
CentOS is a "distribution" with a rather unique description: it is a free (gratis) clone of a commercially-supported "distribution" with all the branding removed. Being enterprise-grade distribution means solid and well-tested; but it also means not having the latest functionality. It also means having a small enough feature set to provide commercial support in a viable manner: and that typically means choosing one technology and sticking with it.
But what if you wanted your entire system to be solid, and well-tested, but want the latest features for one particular package or program? Or what if you really wanted an enterprise system, but wanted to use one of the alternate technoligies that were not selected?
This is where CentOS SIGs come in. The new CentOS is still at its core a clone of an upstream enterprise distribution. But having had success with the Xen4CentOS project, which provided a version of Xen to run on CentOS 6, they have now generalized the process.
This talk will talk about CentOS SIGs: the vision, the structure, what SIGs are available. We will compare and contrast them to other community distro development models like Fedora, OpenSuSE, Debian, Ubuntu, and so forth. We will also share lessons from the CentOS Virt SIG, in which a number of virtualisation and related technologies such as Xen, oVirt, Docker and others collaborate.
"Understanding Open Source and Ubuntu Part 1 of 2" by Kurt von Finck @ eLiber...eLiberatica
This is a presentation held at eLiberatica 2007.
http://www.eliberatica.ro/2007/
One of the biggest events of its kind in Eastern Europe, eLiberatica brings community leaders from around the world to discuss about the hottest topics in FLOSS movement, demonstrating the advantages of adopting, using and developing Open Source and Free Software solutions.
The eLiberatica organizational committee together with our speakers and guests, have graciously allowed media representatives and all attendees to photograph, videotape and otherwise record their sessions, on the condition that the photos, videos and recordings are licensed under the Creative Commons Share-Alike 3.0 License.
Ten years analysing large code bases: a perspectiveRoberto Di Cosmo
Looking back at ten years analysing free an open source distributions, we take a step back and analyse what made this kind of research possible. Availability, traceability and uniformity of the software code base arise as key factors, and they are also essential properties needed for reproducibility and preservation.
This is why we are starting a new project to make sure these properties will be ensured for all software, and not only well structured ecosystems like Debian.
At the end, a call for action to the scientific community to contribute to the project.
CentOS Linux 8 a atteint le stade de "fin de vie" (EOL) le 31 décembre dernier. Depuis le 1er janvier 2022, CentOS Stream est donc devenu uniquement une branche de développement de Red Hat.
Quelles sont les conséquences pratiques de ce changement annoncé quelques mois auparavant ?
Quelles différences entre Red Hat / CentOS et SUSE / openSUSE ?
Quelles solutions s’offrent à vous pour préserver la stabilité de votre infrastructure Linux ?

Compliance in a complex Yocto/Bitbake-based operating system
Compliance with copyright can be a nightmare, especially if the project faces it late in development. Everybody is now figuring out how to use tools and how this could help. We have been tasked with doing it for an entire operating system, something that would take months/man if not years. If you start late, you will finish late. But the gold standard is today to integrate compliance in CI/CD. We present our solutions and those that we have considered or are considering.

Dans le cadre de la licence informatique à Paris 8, un cours qui utilise des technologies libres est proposé. Le but du cours nommé "Compréhension de programmes" est d'initier les étudiants à la lecture de code source écrit par d'autres.
L'enseignante s'est rendu compte que les logiciels libres offrent beaucoup de possibilités dans le cadre de ce cours. Cette présentation décrit la première année de cette expérience.
Training Tomorrow's Engineers by Contributing to Today's Free Software here_and_there
Is there an easy manner to attract students to contribute to free software ? GSoC is a good example. What about trying to extend this experience through the academic year. In this slide there are couple of ideas about how to do that. The project is not yet born and needs to be further investigated.
Libre Semester of Code : Faire travailler les étudiants sur des logiciels lib...here_and_there
Le Libre Semester of Code est une idée née dans le but de proposer aux étudiants en informatique une prolongation de l'expérience GSoC tout au long de l'année universitaire. Cela se ferait en mode projet ou en mode stage. Idée à développer et partager.

19. Interlude — derivatives how to
Free Software 101
Freedom #0, to run the program, for any purpose
Freedom #1, to study how the program works, and change it
Freedom #2, to redistribute copies
Freedom #3, to improve the program, and release improvements
When applied to distros: derived distributions, AKA derivatives
How? 1 take existing packages and add your extras
2 patch & rebuild packages as needed
3 sync periodically
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 13 / 28
20. Debian derivatives
Debian: a base for ≈140 active derivatives — distrowatch.com

very popular (15–20x Debian?)
historical/past correlations 11%
main ↔ corporate Patch
universe ↔ community 74%
heavily customized/forked in main 15%
very close to Debian elsewhere
sprouting its own derivatives (≈80)
Ubuntu
. . . as Debian transitive derivatives

27. How people get involved
(to understand how participation in Debian
can contribute to student formation)
Typical ways to start contributing:
1 join existing packaging teams packaging / development
learn from experienced contributors
learn team work
high quality standards / rigorous procedures / perfectionism (VCS,
patch minimality, software qualification, . . . )
2 adopt orphaned packages packaging
take responsibility, long-term commitment
3 fix bugs development / packaging
in packages you care about
activities: report bugs, submit patches, test others’ patches, . . .
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 21 / 28
28. How people get involved (cont.)
(to understand how participation in Debian
can contribute to student formation)
Typical ways to start contributing:
4 improve Debian infrastructure development
very complex, heterogeneous, real-world infrastructure
no need to be a Debian Developer
most services provide link to corresponding source code and setup
instructions
5 work on non differently technical tasks management, . . .
documentation, translation
design (themes, websites)
communication (newsletter, press releases, press inquiries)
accounting
events (mini-DebConf, DebConf)
video team
...
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 21 / 28
29. Outreach — to students and teachers
nope :-(
i.e. no specific outreach program for teaching
“only” general outreach to all potential contributors
Debian contributor demography, relevant groups:
professional sysadms
students (master & PhD)
researchers
teachers (at all levels)
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 22 / 28
30. Participation in FOSS outreach programs
Also, we do participate in general FOSS outreach programs, with some
success.
Google Summer of Code (GSoC)
[GSoC] is an annual program [. . . ] in which Google awards stipends
(of 5,000 USD, as of 2012) to hundreds of students who successfully
complete a requested FOSS coding project during the summer. —
Wikipedia
participants since 2006 (2nd edition)
non packaging tasks, but software development
e.g. infrastructure, toolchain, . . .
prefer newbie contributors, but accept (student) DDs
2011: 30 applications / 9 accepted / 9 successful
2012: 68 applications / 15 accepted / 12 successful
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 23 / 28
31. Participation in FOSS outreach programs (cont.)
Also, we do participate in general FOSS outreach programs, with some
success.1
Google Code In (GCI)
[GCI] is an annual programming competition sponsored by Google
that allows pre-university students to complete tasks specified by
partnering FOSS organizations.
participated in 2011 (2nd edition)
example tasks:
write 4 manpages
prepare a QA upload
fix a dpkg bug
triage 3-4 bugs
translate a wiki page
had hard time collecting enough tasks in 2012 → drop off

Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 23 / 28
32. Teaching Debian — as sysadm technology
Teaching Debian administration (to train sysadms):
+ highly relevant on the market
Debian is now the most popular Linux distribution on web
servers [ 29.4% of FOSS, 9.6% of total ]
— w3techs.com, January 2012
+ lack of enough trained engineers
= student motivation (in theory)
few, but important Debian-specific skills
reuse other common FOSS skill-sets
(Free) Resources

Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 24 / 28
33. Teaching Debian — as packaging technology
Teaching Debian packaging:
not (yet) as relevant as Debian administration, but growing. . .
. . . and key in specific contexts
e.g. (derivative) distribution editors
e.g. companies with .deb-based deployment work-flows
(Free) Resources

also: apt-get install packaging-tutorial
Already in lecture format with practical exercises — duration 4h–8h,
depending on the class level.
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 25 / 28
34. Using Debian as a teaching platform
Depends on your software needs and its availability in Debian.
Really.
at high school level and below2
Debian Edu (AKA “Skolelinux”) — a school lab, out of the box
http://www.slx.no/en/product
http://wiki.debian.org/DebianEdu
at university level, computer science/engineering
very flexible for labs
good platform for development (using testing)
fresh software, but more tested than development snapshots
plenty of active per-language sub-communities
very good platform for OS-related classes
consistent way to find system-level documentation
easy and consistent way to retrieve sources and investigate more
2
not my area of expertise
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 26 / 28
35. Wrap up
By using and contributing to Debian students can learn:
team work: processes, discipline, peer review, management, . . .
software life-cycle management
development: patching complex code bases
development: complex, world-wide infrastructure
Free Software ethos
Stefano Zacchiroli (Debian) Debian fOSSa 2012 — Lille 27 / 28
