Identifying Operating Systems in GNOME Boxes

One secret sauce of GNOME Boxes is libosinfo. It basically is an umbrella for three components: libosinfo, osinfo-db-tools, and osinfo-db.

libosinfo offers programmatic means to query for information about OSes. osinfo-db-tools is a set of tools that help manipulate and extract information from OS images (such as ISO files). osinfo-db is a database of operating system information describing requirements for virtualized installations as well as virtual drivers and devices that work with each OS in the database.

For a given image file, Boxes will use libosinfo to detect which operating system it contains and assign the appropriate configuration preferences for it.

When an operating system’s data was not present in osinfo-db, we used to treat the image file as an “unknown OS”, which would get set up with the Boxes default configuration preferences. This usually works, but when it fails, it gets really hard for a regular user to use the virtual machine. Think of a wrong virtual video driver causing the guest’s graphic session to hang, or a virtual tablet device getting on the way of gestures being passed to the guest, etc…

For this very reason, we decided to add an extra page in our VM creation assistant that will only get visible for those “unknown” OSes. This page allows you to specify which operating system you intend to install. This way Boxes can use libosinfo to set up your VM with the right configuration preferences for the chosen OS.

If you can’t find your OS in the list, try picking a similar one. For instance, if Linux Mint isn’t on the list, you are probably better off telling Boxes it is a Ubuntu or Debian based OS.

Not choosing anything on this page is also fine, in this case, Boxes will go with its defaults.

New operating systems can be added to the osinfo-db by creating merge requests in their GitLab repository.

This (with some more polishing) and other changes will be available in GNOME Boxes 3.38. If you can’t wait, give a go to our *unstable* nightly Flatpak.

GUADEC 2020: Intern lightning talks

Hi, I hope you are all enjoying GUADEC! I am just passing by to let you know that on Monday 27th, 18:00 UTC, we will have our traditional Intern lightning talks where you will get to see our Outreachy and Google Summer of Code  interns present their projects.

This year we will also have a few past interns sharing their stories about their experiences as interns and how GNOME has helped their professional careers.

https://events.gnome.org/event/14 (Track 1)

Stay tuned!

Let’s welcome our 2020 GSoC interns!

It is Google Summer of Code season again and this year the GNOME project is lucky to have 14 new interns working on various projects ranging from improvements in our app ecosystem to core components and infrastructure.

The first period, from May 4 to June 1, is the Community Bonding period. Interns are expected to flock into our communication channels, ask questions, and get to know our project’s culture. Please, join me in welcoming our students and making sure they feel at home in our community.

This year we will be using Discourse as our main communication channel regarding the program, therefore if you are a mentor or intern, please make sure to check https://discourse.gnome.org/c/community/outreach for announcements. Feel free to create new topics if you have any questions. The GNOME GSoC admins will be monitoring the Outreach category and answering any doubts you might have.

Here is the list of interns and their respective projects https://summerofcode.withgoogle.com/organizations/5428225724907520/#projects

Tips for students

First of all, congratulations! This is just the beginning of your GNOME journey. Our project is almost 23 years old and likely older than some of you, but our community gets constantly renewed with new contributors passionate about software freedom. I encourage you to take some time to watch the recordings of Jonathan Blandford’s “The History of GNOME” talk in GUADEC 2017 so you can grasp how we have grown and evolved since 1997.

The first thing you want to do after celebrating your project’s acceptance is to contact your mentor (if they haven’t contacted you first).

Second, introduce yourself on our “Say Hello” topic! Don’t forget to mention that you are in GSoC 2020, the project you will be working on, and who’s your mentor.

Third, set up a blog where you will be logging your progress and talking directly to the broader community. In case you need help with that, ask your mentors or the GSoC admins. Intern blogs get added to Planet GNOME, which is a feed aggregator of posts written by dozens of GNOME Foundation members.

Many of us read Planet GNOME daily! Besides, some of our active contributors have participated as interns in past editions of GSoC. You can dig for their blogposts and get a better sense of how these progress reports are written.

It is totally normal for you to have questions and doubts about the program, to help with that, we will be hosting a Q&A on May 12 at 17:00 UTC in our RocketChat channel. All of you will receive an invitation by email this week too. If you can’t make it, feel free to join the channel at any time and ask questions there as well.

If during your internship you have a problem with your mentor (lack of communication, or misunderstandings, or deep disagreements, or
anything else), don’t hesitate to report that to the GNOME GSoC administrators.

Last but not least, have fun!

Announcing “Connections”: a modern remote desktop client for GNOME

Yes! Connections is a brand new app that I put together in the last month. It is a remote desktop client for the VNC and RDP protocols on top of the same backend code that we were already using in GNOME Boxes*: gtk-vnc and gtk-frdp.

The main motivation to write this application is to have a drop-in replacement for Vinagre** that is modern, easier to maintain and follows the HIG. Besides, we want to have a GNOME app to point users to when they ask for more/advanced remote-connection options in Boxes.

The app is at an early development stage where it can be tested and even used for simple remote connection tasks. I started filling issues in GitLab so others can pick up tasks that they might be interested in helping.

It basically has the same code base as GNOME Boxes for the protocol/display specific code, so you will likely get the same experience as with remote connections in Boxes today. Of course, the plan is for later to add more and more remote connection specifics to empower our users without cluttering our interface. That’s the GNOME Way™. 🙂

Connections can be downloaded from Flathub by clicking the button below.

Download on Flathub

For now, I would NOT encourage downstream packagers to distribute the application, since lots of it will change until our 3.38 (first stable) release. Flatpak allows for the control we need when starting the development of a brand new application, and this way we can strive for the best experience our users can have by delivering updates directly to them.

Putting GNOME Connections together wouldn’t have been easier without Flatpak, GNOME Builder, GNOME Boxes, Vala, and GTK. Our platform is becoming very accessible for native application development thanks to all these efforts. We all appreciate it! ♥

* These features will live in Boxes for some time to allow for user migration, but they will be likely removed by the time we will be releasing 3.40.

** Vinagre is now in maintenance mode and won’t be getting new features. Eventually, we will sunset it.

DevConf.CZ 2020

Once again, DevConf.CZ, is our meeting-while-freezing winter conference in Brno. For this year I cooked up two talks:

An hour-long talk about Portals during the first day of the conference. The room was almost full and the questions were very relevant. A few attendees met me after the talk seeking help to make their apps start using Portals and with ideas for new Portals.  You can watch the recordings below:

On the last conference day, I had a quick twenty minutes talk about GNOME Boxes in the virtualization track. The audience wasn’t our known faces from the desktop talks, so I got the chance to show Boxes for the first time for a bunch of people. I did a quick presentation with live demos and Q&A. It was a success IMHO. Check the recordings below:

Besides, I participated in the “Diversity and Inclusion” and “Women in Open source” meetups. It was a good opportunity to see what other teams are doing to be more diverse and also to share my personal experiences with mentoring with Outreachy.

Langdon White had a talk on Fedora Silverblue raising important questions about the development workflow in it. I was glad some of their issues were already addressed and fixed, but I recommend to those who didn’t attend this talk to watch the recordings. It is important feedback.

I felt honored to be mentioned in Rebecca Fernandez’s talk about “Growing your career via open source contributions”, where she had slides showing people’s stories, including mine.

I managed to catch up with the developments of the virgil driver on Windows in order to support Direct3D, and discuss other future developments with folks from the SPICE team.

Other than that, I attended many podman/containers talks to better understand their development workflows and how we could accommodate these workflows in Silverblue. I spoke to Red Hatters from other teams that need CodeReadyContainers to test their applications, and how we could improve their workflow in Fedora Workstation.

Lastly, I had a great time with [delicious] food and drinks at the DevConf Party in Fleda, which is 200 meters away from our flat. 🙂

Ten Years Contributing to GNOME!

Time flies! Exactly ten years ago today I made my first contribution to GNOME.

I rarely celebrate recurring dates but this is a nice rounded number that serves as the perfect excuse for me to publish this letter of appreciation to our community.

For me, it all started with a hardware vendor trying to cheap their desktop machine’s price by putting Linux on it. Initially, we didn’t have internet at home, so I spent a significant amount of time just exploring the OS and toggling every knob I could find in the UI. The first issues I encountered were missing translations. Googling for that lead me to discover the wonders of Free and Open Source Software. I could contribute that missing translation!

Playing with computers wasn’t always my hobby. I had an offline childhood, despite being a 90’s kid. A career in anything computer-related was unthinkable given our economic reality at the time. My parents are low paid public servants, so I was inclined to find myself a job in the public sector too. I had strong feelings about teaching, just like my mom, but computers… well, they are addictive!

When I was sixteen years old I made my first contributions to the Brazilian Portuguese translation team in GNOME. This was also when I started reading Planet GNOME. Your neckless floating heads were god-like figures to me. I couldn’t understand 90% of the topics discussed due to my limited English and technical skills at the time, but I basically just kept on reading everything. Really. IRC logs, mailing lists, blog aggregators, social media timelines… everything scrolled all the way to the bottom. This is indeed overwhelming, but it has helped me put everything together and ~kind of~ grasp what software development looked like.

Because of my new found passion for computers, and GNOME specifically, I decided to study computer science. Since then I have participated in Google Summer of Code, worked as a contractor with GNOME technologies, and landed my current (and dream) job at Red Hat’s Desktop Team. It’s been five years now since I moved to Brno, and these have been *by far* the happiest years of my life. I have now experienced so many things that were unthinkable back when I started, I have been able to help my family, and start a family of my own here in my new home, Czech Republic.

All of this wouldn’t be possible without those who came before, paving the way for me.

This way, I wanted to make this Ten Year Celebration about you, GNOME community member that might not know how much positive change you might be bringing to other people’s lives.

Thank YOU!

Try the GNOME Nightly VM images with GNOME Boxes

It was a long time overdue but we now have bootable VM images for GNOME again. These VMs are good for testing and documenting new features before they reach distros.

To provide the best experience in terms of performance and host-guest integration, we landed in BoxesDevel (Nightly GNOME Boxes) an option to create GNOME VMs with the correct device drivers and configurations assigned to it. You know…the Boxes way™.

Installing GNOME Boxes (Nightly)

1. Set up our nightlies Flatpak repository:

flatpak remote-add --if-not-exists gnome-nightly https://nightly.gnome.org/gnome-nightly.flatpakrepo

2. Install Boxes

flatpak install gnome-nightly org.gnome.BoxesDevel

Testing the GNOME VM image

1. Download a recent VM snapshot (linked on the unstable release announcements). It is a qcow2 file.

2. Open the new VM dialog in Boxes and click on the “GNOME Nightly” entry in the Featured Downloads section. It will open a file chooser.

Screenshot

3. After selecting the qcow2 file downloaded in step one, you can continue to Create a VM. Once the creation is over, you will be able to start the VM by clicking in it on the icon view.

Future developments

We haven’t reached a consensus yet on how we are going to distribute/store/host these VM images, that’s why we have the extra-step before, requiring to pick the file in a file chooser.

In the near future, we will host the images and you will be able to download them directly from GNOME Boxes.

Also, the latest image as of today (3.35.91) doesn’t come with spice-vdagent. It should be included in the next builds, allowing for a maximum host-guest integration like dragging and dropping files from host to guest, automatic resolution, etc…

This is just the beginning. Stay tuned!

GNOME 3.34 Release Party in Brno, Czech Republic

In September 25th we had once more a local meetup in Brno to celebrate another fantastic GNOME Release!

GNOME “Thessaloniki” 3.34 is out now and will be reaching distros in the following months. This version is the result of the work of approximately 777 contributors in the last six months. For more details, check out the release notes.

Our Brno celebrations this cycle were held in Schrott, a place with a wide variety of beers and a neat industrial decor. Dominika Vagnerova arranged delicious GNOME themed cupcakes with eatable app icons that went along pretty well with the drinks.

This was an excellent opportunity for us to sit down, relax, and chat about GNOME, Free Software, and all things that bring us together.

More photos of the event are available in our shared album, including ~exclusive~ pictures of application maintainers eating their apps’ cupcakes. 🙂

Thanks everyone that showed up, special thanks to Dominika for organizing the event and Rishi for the photos. Stay tuned for 3.36!

GUADEC 2019

Meeting my fellow GNOMies is something I look forward to every year. For eight years now I have traveled to participate in GUADEC and returned home with my head thinking of next year’s edition of the conference.

This year, I was busy with lots of activities, but still, I managed to chill with the friends I work with online throughout the whole year.  Putting faces into new names is also something very pleasant in these opportunities.

In the pre-registration party, I hosted a “Newcomers dinner“. Not many people could attend because of their personal travel plans, but those that participated were excited about being at the conference and getting to know so many cool people.

Besides that, it was the first GUADEC that we had a trained Code of Conduct Incident Response Team. We did an extensive training workshop with Otter Tech. Highly recommended!

Right at the first talks day, I hosted the interns’ lightning talks, that thanks to the amazing local team, are recorded and available online. The audience (and myself) were enthusiastic about hearing from the interns. After a few years of organizing these activities, I can still remember myself being an intern and giving my lightning talk back in 2012. Time flies! 🙂

The quality of talks is always outstanding, so I listed below the ones I attended and recommend watching online:

  • Desktop Secrets Management for the Future by Daiki Ueno: I have lately been heavily interested in application sandboxing, so it was great catching up with Daiki’s work and ideas for our keyring story.
  • Managing GNOME Sessions with Systemd by Benjamin Berg and Iain Lane: It is being great and educative to follow their progress throughout the years on this task. The cherry on the cake is seeing this work landing and explained in Benjamin’s blog post.
  • Designing Multi-Process Application Security by Christian Hergert: Watching Christian talk is always exciting and educational. We are lucky to have such skillful developer in our project, and I definitely learned valuable lessons on application security.
  • Portals – Principles and Practice by Matthias Clasen: As I mentioned above, I have been lately interested in application sandboxing, so I couldn’t miss Matthias’ talk on Portals. It is so nice to see our application ecosystem evolving with Flatpak and its technologies.
  • GNU HEALTH: The Fight for our Rights in the Public Health System by Luis  Falcón: I personally care a lot about such social issues especially for being myself originally from the developing world, where people often don’t enjoy the same rights people in the developed world take for granted. The keynote was very well chosen.
  • Environmentally Friendly GNOME by Philip Withnall: IMPORTANT! We are running out of time to stop climate change, and I think every segment of society needs to discuss the issue. I hope to see the ideas discussed in this talk brought forward in our community.
  • Simple is Hard – Creating Beautiful App Icons by Jakub Steiner: Jimmac is so creative and talented that I can’t ever miss his talks. It is great to work with the design team on a daily basis, and this was a good opportunity to better understand their creative processes.
  • Accessibility Features for Mutter/GNOME Shell on Wayland by Oliver Fourdan: This work is very important. Oliver has made significant progress in shrinking the accessibility gap we currently have. Thanks for that!
  • Designing GNOME Mobile Apps by Tobias Bernard: Exciting work! It was great to see their progress on making GNOME apps adaptative. I hope this can make our platform even more attractive to vendors interested in building mobile OSes.
  • The Growth of GNOME by Neil McGovern: It is very reassuring listening to Neil describe the plans of growth for the GNOME Foundation.
  • Lightning Talks: It is always fun to see fellow GNOMies delivering their talk considering the lightning talks’ time constraint. 😀

During the BoF days, I conducted the Newcomers workshop, where we had various participants learning hands-on how to make their first code contribution to the GNOME project. Thanks everyone that showed up to participate and to help newcomers. I hope we can improve and repeat the workshop all over the world. GNOME.Asia will have its edition of the Newcomers workshop, so if you will be around in Gresik, don’t miss it!

In the Boxes BoF we discussed a roadmap to land some highly anticipated features such as UEFI support, Import/Export VMs, etc… Stay tuned here and also in the @BoxesGNOME Twitter account, where I have been doing outreach for our project by interacting with a part of our user base [wherever they are].

The social events were a blast. We had delicious food, great music, and passionate conversations at the Gala Dinner. The Picnic Day was fun and relaxing. The Museum BoF was enjoyable and nerdy (how I like it ;-)).

Checkout the photos!

Thanks to my employer, Red Hat, for sponsoring my trip and accommodation in the beautiful Thessaloniki!

Newcomers workshop @ GUADEC 2019

This year’s GUADEC is approaching and I can already feel people’s excitement while talking about our annual conference.  It is important that we benefit from having so many GNOMies together in the same location to help the next generation to get started in our project. For this reason, we are planning a workshop during the first day of the BoFs (check our wiki page for more info).

The Newcomers Workshop aims at helping newcomers solve their first Gitlab issue. Historically, Carlos Soriano has championed the initiative (thank Carlos when you see him) and I have participated, guiding dozens of people in the universities here in Brno. In the past, other community members were organizing the workshop all over the world. We plan to expand the initiative by having even more GNOME contributors organizing similar events at a local level.

In the workshop we go step-by-step in the GNOME Newcomers Guide, making sure nobody gets stuck on anything.  As simple as that. The more GNOME developers participate the better, since we can benefit from their project-specific expertise.

The workshop is taking place on August 26th, and anybody interested in making their first contribution is welcome! Save the date!
