Congratulations!

We are happy to announce that registration for DebConf20 is now open. The event will take place from August 23rd to 29th, 2020 at the University of Haifa, in Israel, and will be preceded by DebCamp, from August 16th to 22nd.

Although the Covid-19 situation is still rather fluid, as of now, Israel seems to be on top of the situation. Days with less than 10 new diagnosed infections are becoming common and businesses and schools are slowly reopening. As such, we are hoping that, at least as far as regulations go, we will be able to hold an in-person conference. There is more (and up to date) information at the conference's FAQ. Which means, barring a second wave, that there is reason to hope that the conference can go forward.

For that, we need your help. We need to know, assuming health regulations permit it, how many people intend to attend. This year probably more than ever before, prompt registration is very important to us. If after months of staying at home you feel that rubbing elbows with fellow Debian Developers is precisely the remedy that will salvage 2020, then we ask that you do register as soon as possible.

Sadly, things are still not clear enough for us to make a final commitment to holding an in-person conference, but knowing how many people intend to attend will be a great help in making that decision. The deadline for deciding on postponing, cancelling or changing the format of the conference is June 8th.

To register for DebConf20, please visit our website and log into the registration system and fill out the form. You can always edit or cancel your registration, but please note that the last day to confirm or cancel is July 26th, 2020 23:59:59 UTC. We cannot guarantee availability of accommodation, food and swag for unconfirmed registrations.

We do suggest that attendees begin making travel arrangements as soon as possible, of course. Please bear in mind that most air carriers allow free cancellations and changes.

Any questions about registrations should be addressed to registration@debconf.org.

Bursary for travel, accomodation and meals

In an effort to widen the diversity of DebConf attendees, the Debian Project allocates a part of the financial resources obtained through sponsorships to pay for bursaries (travel, accommodation, and/or meals) for participants who request this support when they register.

As resources are limited, we will examine the requests and decide who will receive the bursaries. They will be destined:

• Debian funded bursaries are available to active Debian contributors.
• Debian diversity bursaries are available to newcomers to Debian/DebConf. Especially from under-represented communities.

Giving a talk, organizing an event or helping during DebConf20 is taken into account when deciding upon your bursary, so please mention them in your bursary application.

For more information about bursaries, please visit Applying for a Bursary to DebConf

Attention: deadline to apply for bursaries using the registration form before May 31st, 2019 23:59:59 UTC. This deadline is necessary in order to the organisers to have some time to analyze the requests.

To register for the Conference, either with or without a bursary request, please visit: https://debconf20.debconf.org/register

Participation to DebConf20 is conditional to your respect of our Code of Conduct. We require you to read, understand and abide by this code.

DebConf would not be possible without the generous support of all our sponsors, especially our Platinum Sponsor Lenovo and Gold Sponsors deepin and Matanel Foundation. DebConf20 is still accepting sponsors; if you are interested, or think you know of others who would be willing to help, please get in touch!

From time to time, we get questions in Debian about our official channels of communication and questions about the Debian status of who may own similarly named websites.

The main Debian website www.debian.org is our primary medium of communication. Those seeking information about current events and development progress in the community may be interested in the Debian News section of the Debian website. For less formal announcements, we have the official Debian blog Bits from Debian, and the Debian micronews service for shorter news items.

Our official newsletter Debian Project News and all official announcements of news or project changes are dual posted on our website and sent to our official mailing lists debian-announce or debian-news. Posting to those mailing lists is restricted.

We also want to take the opportunity to announce how the Debian Project, or for short, Debian is structured.

Debian has a structure regulated by our Constitution. Officers and delegated members are listed on our Organizational Structure page. Additional teams are listed on our Teams page.

The complete list of official Debian members can be found on our New Members page, where our membership is managed. A broader list of Debian contributors can be found on our Contributors page.

If you have questions, we invite you to reach the press team at press@debian.org.

Debian continues participating in Outreachy, and we'd like to welcome our new Outreachy interns for this round, lasting from December 2019 to March 2020.

Anisa Kuci will work on Improving the DebConf fundraising processes, mentored by Karina Ture and Daniel Lange.

Sakshi Sangwan will work on Packaging GitLab's JS Modules, mentored by Utkarsh Gupta, Sruthi Chandran and Pirate Praveen.

Congratulations, Anisa and Sakshi! Welcome!

From the official website: Outreachy provides three-month internships for people from groups traditionally underrepresented in tech. Interns work remotely with mentors from Free and Open Source Software (FOSS) communities on projects ranging from programming, user experience, documentation, illustration and graphical design, to data science.

The Outreachy programme is possible in Debian thanks to the efforts of Debian developers and contributors who dedicate their free time to mentor students and outreach tasks, and the Software Freedom Conservancy's administrative support, as well as the continued support of Debian's donors, who provide funding for the internships.

Join us and help extend Debian! You can follow the work of the Outreachy interns reading their blogs (they are syndicated in Planet Debian), and chat with us in the #debian-outreach IRC channel and mailing list.

Today, the Debian Project pledges to donate $5,000 to the GNOME Foundation in support of their ongoing patent defense. On October 23, we wrote to express our support for GNOME in an issue that affects the entire free software community. Today we make that support tangible.

"This is bigger than GNOME," said Debian Project Leader Sam Hartman. "By banding together and demonstrating that the entire free software community is behind GNOME, we can send a strong message to non-practicing entities (patent trolls). When you target anyone in the free software community, you target all of us. We will fight, and we will fight to invalidate your patent. For us, this is more than money. This is about our freedom to build and distribute our software."

"We're incredibly grateful to Debian for this kind donation, and also for their support," said Neil McGovern, Executive Director of the GNOME Foundation. "It's been heartening to see that when free software is attacked in this way we all come together on a united front."

If GNOME needs more money later in in this defense, Debian will be there to support the GNOME Foundation. We encourage individuals and organizations to join us and stand strong against patent trolls.

In 2012, the Debian Project published our Position on Software Patents, stating the threat that patents pose to Free Software.

The GNOME Foundation has announced recently that they are fighting a lawsuit alleging that Shotwell, a free and Open Source personal photo manager, infringes a patent.

The Debian Project firmly stands with the GNOME Foundation in their efforts to show the world that we in the Free Software communities will vigorously defend ourselves against any abuses of the patent system.

Please read this blog post about GNOME's defense against this patent troll and consider making a donation to the GNOME Patent Troll Defense Fund.

The Salsa admin team provides the following report about the failed migration of the Docker container registry. The Docker container registry stores Docker images, which are for example used in the Salsa CI toolset. This migration would have moved all data off to Google Cloud Storage (GCS) and would have lowered the used file system space on Debian systems significantly.

The Docker container registry is part of the Docker distribution toolset. This system supports multiple backends for file storage: local, Amazon Simple Storage Service (Amazon S3) and Google Cloud Storage (GCS). As Salsa already uses GCS for data storage, the Salsa admin team decided to move all the Docker registry data off to GCS too.

Migration and rollback

On 2019-08-06 the migration process was started. The migration itself went fine, although it took a bit longer than anticipated. However, as not all parts of the migration had been properly tested, a test of the garbage collection triggered a bug in the software.

On 2019-08-10 the Salsa admins started to see problems with garbage collection. The job running it timed out after one hour. Within this timeframe it not even managed to collect information about all used layers to see what it can cleanup. A source code analysis showed that this design flaw can't be fixed.

On 2019-08-13 the change was rolled back to storing data on the file system.

Docker registry data storage

The Docker registry stores all of the data sans indexing or reverse references in a file system-like structure comprised of 4 separate types of information: Manifests of images and contents, tags for the manifests, deduplicaed layers (or blobs) which store the actual data, and lastly links which show which deduplicated blogs belong to their respective images, all of this does not allow for easy searching within the data.

The file system structure is built as append-only which allows for adding blobs and manifests, addition, modification, or deletion of tags. However cleanup of items other than tags is not achievable within the maintenance tools.

There is a garbage collection process which can be used to clean up unreferenced blobs, however according to the documentation the process can only be used while the registry is set to read-only and unfortunately it cannot be used to clean up unused links.

Docker registry garbage collection on external storage

For the garbage collection the registry tool needs to read a lot of information as there is no indexing of the data. The tool connects to the storage medium and proceeds to download … everything, every single manifest and information about the referenced blobs, which now takes up over 1 second to process a single manifest. This process will take up a significant amount of time, which in the current configuration of external storage would make the clean up nearly impossible.

Leasons learned

The Docker registry is a data storage tool that can only properly be used in append-only mode. If you never cleanup, it works well.

As soon as you want to actually remove data, it goes bad. For Salsa clean up of old data is actually a necessity, as the registry currently grows about 20GB per day.

Next steps

Sadly there is not much that can be done using the existing Docker container registry. Maybe GitLab or someone else would like to contribute a new implementation of a Docker registry, either integrated into GitLab itself or stand-alone?

26 years ago today in a single post to the comp.os.linux.development newsgroup, Ian Murdock announced the completion of a brand new Linux release named Debian.

Since that day we’ve been into outer space, typed over 1,288,688,830 lines of code, spawned over 300 derivatives, were enhanced with 6,155 known contributors, and filed over 975,619 bug reports.

We are home to a community of thousands of users around the globe, we gather to host our annual Debian Developers Conference DebConf which spans the world in a different country each year, and of course today's many DebianDay celebrations held around the world.

It's not too late to throw an impromptu DebianDay celebration or to go and join one of the many celebrations already underway.

As we celebrate our own anniversary, we also want to celebrate our many contributors, developers, teams, groups, maintainers, and users. It is all of your effort, support, and drive that continue to make Debian truly: The universal operating system.

Happy DebianDay!

Today, Saturday 27 July 2019, the annual Debian Developers and Contributors Conference came to a close. Hosting more than 380 attendees from 50 different countries over a combined 145 event talks, discussion sessions, Birds of a Feather (BoF) gatherings, workshops, and activities, DebConf19 was a large success.

The conference was preceded by the annual DebCamp held 14 July to 19 July which focused on individual work and team sprints for in-person collaboration toward developing Debian and host to a 3-day packaging workshop where new contributors were able to start on Debian packaging.

The Open Day held on July 20, with over 250 attendees, enjoyed presentations and workshops of interest to the wider audience, a Job Fair with booths from several of the DebConf19 sponsors and a Debian install fest.

The actual Debian Developers Conference started on Sunday 21 July 2019. Together with plenaries such as the the traditional 'Bits from the DPL', lightning talks, live demos and the announcement of next year's DebConf (DebConf20 in Haifa, Israel), there were several sessions related to the recent release of Debian 10 buster and some of its new features, as well as news updates on several projects and internal Debian teams, discussion sessions (BoFs) from the language, ports, infrastructure, and community teams, along with many other events of interest regarding Debian and free software.

The schedule was updated each day with planned and ad-hoc activities introduced by attendees over the course of the entire conference.

For those who were not able to attend, most of the talks and sessions were recorded for live streams with videos made, available through the Debian meetings archive website. Almost all of the sessions facilitated remote participation via IRC messaging apps or online collaborative text documents.

The DebConf19 website will remain active for archival purposes and will continue to offer links to the presentations and videos of talks and events.

Next year, DebConf20 will be held in Haifa, Israel, from 23 August to 29 August 2020. As tradition follows before the next DebConf the local organizers in Israel will start the conference activites with DebCamp (16 August to 22 August), with particular focus on individual and team work toward improving the distribution.

DebConf is committed to a safe and welcome environment for all participants. During the conference, several teams (Front Desk, Welcome team and Anti-Harassment team) are available to help so both on-site and remote participants get their best experience in the conference, and find solutions to any issue that may arise. See the web page about the Code of Conduct in DebConf19 website for more details on this.

Debian thanks the commitment of numerous sponsors to support DebConf19, particularly our Platinum Sponsors: Infomaniak, Google and Lenovo.

You've always dreamt of a faithful pet? He is here, and his name is Buster! We're happy to announce the release of Debian 10, codenamed buster.

Want to install it? Choose your favourite installation media and read the installation manual. You can also use an official cloud image directly on your cloud provider, or try Debian prior to installing it using our "live" images.

Already a happy Debian user and you only want to upgrade? You can easily upgrade from your current Debian 9 "stretch" installation; please read the release notes.

Do you want to celebrate the release? We provide some buster artwork that you can share or use as base for your own creations. Follow the conversation about buster in social media via the #ReleasingDebianBuster and #Debian10Buster hashtags or join an in-person or online Release Party!

The Debian Release Team in coordination with several other teams are preparing the last bits needed for releasing Debian 10 "buster" on Saturday 6 July 2019. Please, be patient! Lots of steps are involved and some of them take some time, such as building the images, propagating the release through the mirror network, and rebuilding the Debian website so that "stable" points to Debian 10.

If you are considering create some artwork on the occasion of buster release, feel free to send us links to your creations to the (publicly archived) debian-publicity mailing list, so that we can disseminate them throughout our community.

Follow the live coverage of the release on https://micronews.debian.org or the @debian profile in your favorite social network! We'll spread the word about what's new in this version of Debian 10, how the release process is progressing during the weekend and facts about Debian and the wide community of volunteer contributors that make it possible.

If you want to celebrate the release of Debian 10 buster, join one of the many release parties or consider organizing one in your city! Celebration will also happen online on the Debian Party Line.
