Georges Stavracas: On Building Bridges

13 de Julho de 2021, 20:07, por Planeta GNOME Brasil - 0sem comentários ainda

After reading "Community Power Part 4: The GNOME Way", unlike the other articles of the series, I was left with a bittersweet taste in my mouth. Strangely, reading it triggered some intense negative feelings on me, even if I fundamentally agree with many of the points raised there. In particular, the "The Hows" and "In … Continue reading On Building Bridges



Georges Stavracas: Dark & light style selector in To Do

2 de Julho de 2021, 17:45, por Planeta GNOME Brasil - 0sem comentários ainda

We just started the development cycle of GNOME 41 for GNOME To Do, and the first new feature is a dark & light style variant selector: There's a lot to be done to make To Do actually useful. The inbox view is essentially useless as it is right now. It really needs more system-wide integration … Continue reading Dark & light style selector in To Do



Felipe Borges: Integrating sandboxed Vala apps with the host system through xdg-desktop-portals

16 de Junho de 2021, 13:35, por Planeta GNOME Brasil - 0sem comentários ainda

Portals are a mechanism through which applications can interact with the host environment from within a sandbox. They give the ability to interact with data, files, and services without the need to add sandbox permissions.

Examples of capabilities that can be accessed through portals include opening files through a file chooser dialog, or printing. More information about portals can be found in Sandbox Permissions.

Some portals, such as the FileChooser one, provide an almost seamless experience without much extra code on the app side. For other portals, you usually need some code to talk to the portal’s DBus interface or use libportal.

Vala was designed specifically for the development of GNOME apps, and it has some nice syntax-sugar that makes the communication with DBus pretty simple to implement.

GNOME Boxes is written in Vala and, for this reason, instead of consuming libportal, I introduced a small singleton Portal class that centralizes the whole portal communication logic for the app. This turned out to be quite convenient, so I am copy-pasting it in other Vala apps I work on, and sharing this here in case it can be useful to you too. 🙂

This works because in Vala you can define a namespace matching the desired DBus interface name and with annotations, you can bind objects, properties, and methods to a DBus service. See the Vala DBus Client Samples for more examples.

With the Portal singleton, a call to the Background portal requesting permission for the app to run in the background gets as simple as:

var portals = Portals.get_default ();
yield portals.request_to_run_in_background ((response, results) => {
    if (response == 0)
        // do something...
});

Notice that this is an async call and you may pass a callback to handle its response.

Nothing written here is new, but I thought it was worth sharing this snippet to help others make their apps integrate with xdg-desktop-portals and reduce the unnecessary exposition of user data in sandboxed environments.



Felipe Borges: GNOME LATAM 2021 was a real blast!

4 de Junho de 2021, 11:31, por Planeta GNOME Brasil - 0sem comentários ainda

This year, motivated by the success of virtual events like GNOME Asia and GNOME Onboard Africa, we decided to organize a GNOME LATAM (virtual) conference. The event was a success, with a nice mix of Spanish and Portuguese-speaking presenters. The recordings are now available and (if you understand Spanish or Portuguese) I highly encourage you to check what the Latin American GNOMies are up to. 🙂

  • Juan Pablo Ugarte, from Argentina, that most of you GNOME people know from his work on Glade, had an interesting talk showing his new project: “Cambalache UI Maker”: A modern Glade replacement for GTK4. Juan hasn’t open sourced it yet, but you’ll see it when he pops up in Planet GNOME.
  • Claudio Wunder, from Germany, that you may know from the GNOME engagement team, did a presentation about the engagement team’s work in GNOME and discussed the challenges of managing online communities with its cultural differences and all. Claudio studied in Brazil and speaks Portuguese fluently.
  • Daniel Garcia Moreno, from Spain, that you may know from Endless and Fractal, had a talk sharing his experiences mentoring in GSoC and Outreachy. This was also a good opportunity to introduce the programs to the Latin American community, which is underrepresented in FOSS.
  • me, from Brazil :D, presented a “Developing native apps with GTK talk” where I write up a simple web browser in Python, with GTK and WebKitGtk, while I comment on the app development practices we use in GNOME, and present our tooling such as DevHelp, GtkInspector, Icon Browser, GNOME Builder, Flatpak, etc…
  • Martín Abente Lahaye, from Paraguay, that you may know from GNOME, Sugar Labs, Endless, and Flatseal, had a presentation about GNOME on phones. He commented on the UX of GNOME applications and Phosh in phones, and highlighted areas where things can be improved.
  • Cesar Fabian Orccon Chipana, from Perú, former GSoC intern for GNOME, GStreamer, did an extensive demo of GStreamer pipelines, explaining GStreamer concepts and all. He had super cool live demos!
  • Rafael Fontenelle, from Brazil, is a coordinator of the pt_BR translation team for many years and translates a huge portion of GNOME himself. He did a walk-through of the GNOME translation processes, sharing tips and tricks.
  • Daniel Galleguillos + Fernanda Morales, from Chile, from the GNOME Engagement team, presented design work for the GNOME engagement team. Showing tools and patterns they use for doing event banners, swag, social media posts, and all. Daniel was also responsible for editing the event recordings. Thanks a lot, Daniel!
  • Fabio Duran Verdugo and Matías Rojas-Tapia, from Chile, a long-time GNOME member, presented Handibox. An accessibility tool they are working on at their university to help users with motor impairment use desktop computers. Inspiring!
  • Georges Basile Stavracas Neto, from Brazil, you may know from Endless and GNOME Shell, presented a very nice summary about the GNOME design philosophy and the changes in GNOME Shell 40 and their plans for the future.
  • The event was opened and closed by Julita Inca Chiroque, from Peru, a long-time GNOME Foundation member. Thanks a lot, Julita!

I hope we can make this a tradition and have a GNOME LATAM edition yearly! Thanks a lot to all attendees!



Felipe Borges: Let’s welcome our new interns!

18 de Maio de 2021, 14:59, por Planeta GNOME Brasil - 0sem comentários ainda

It is that time of the year again when we get to meet our new interns participating in both Outreachy and Google Summer of Code. This year the GNOME Project is proud to sponsor two Outreachy internships for the May-August season and to mentor 12 students in GSoC 2021!

Our Outreachy projects are listed here, and you can find our GSoC projects here.

Our interns have received an email with instructions for the community bonding period, and you will start seeing their blog posts appearing in Planet GNOME very soon. Make sure you say “hello” and make them feel welcome in our project. Keep in mind that beyond the project’s tasks, we want them to become long-term contributors and, later on, Foundation members. You also will have a chance to get to know about their projects during our Intern Lightning Talks at GUADEC.

If you have any doubt about our participation in these programs, feel free to contact the GNOME GSoC admins or join the #soc channel.

Happy hacking!



Felipe Borges: Student applications for Google Summer of Code 2021 are now open!

30 de Março de 2021, 9:52, por Planeta GNOME Brasil - 0sem comentários ainda

It’s that time of the year when we see an influx of students interested in Google Summer of Code.

Some students may need some pointers to where to get started. I would like to ask GNOME contributors to be patient with the student’s questions and help them find where to get started.

Point them at https://wiki.gnome.org/Outreach/SummerOfCode/Students for overall information regarding the program and our project proposals. Also, help them find mentors through our communication channels.

Many of us have been Outreachy/GSoC interns and the positive experiences we had with our community were certainly an important factor making us long-term contributors.

If you have any doubts, you can ask them in the #soc channel or contact GNOME GSoC administrators.

Happy hacking!

Felipe Borges: Call for Project ideas for Google Summer of Code 2021

27 de Janeiro de 2021, 15:46, por Planeta GNOME Brasil - 0sem comentários ainda

It is that time of the year again when we start gathering ideas for Google Summer Code.

This time around we will be posting and discussing proposals in GNOME’s GitLab instance. Therefore, if you have a project idea that fits Google Summer of Code, please file an issue at https://gitlab.gnome.org/Teams/Engagement/gsoc-2021/-/issues/new using the “Proposal” template.

Everybody is welcome to add ideas, but it would be nice to verify whether the ideas are realistic and mentorship for it will be available. We encourage you to discuss your ideas with designers in #gnome-design to get their input and plan collaboration, especially if your ideas are related to one of the core GNOME modules.

Keep in mind that there are a few changes in GSoC this year:

  1. Smaller project size all students participating in the 2021 program will be working on a 175 hour project (instead of a 350 hr project). This change will also result in a few other changes including the student stipend being cut in half.
  2. Shortened coding period – the coding period will be 10 weeks with a lot more flexibility for the mentor and student to decide together how they want to spread the work out over the summer. Some folks may choose to stick to a 17-18 hour a week schedule with their students, others may factor in a couple of breaks during the program (for student and mentor) and some may have students focus 30 hours a week on their project so they wrap up in 6 weeks. This also makes it a lot easier for students with finals or other commitments (weddings, etc.) to adjust their schedules.
  3. 2 evaluations (instead of 3) – There will be an evaluation after 5 weeks and the final evaluation will take place after the 10th week. We are also no longer requiring students complete their first evaluation (though we encourage them to do so), so if a student doesn’t complete the first evaluation they will not automatically be removed from the program. They are still required to complete the final evaluation.
  4. Eligibility requirements – In 2020 there are many ways students are learning and we want to acknowledge that so we will be allowing students who are 18 years old AND currently enrolled (or accepted into) a post-secondary academic program as of May 17, 2021 or have graduated from a post-secondary academic program between December 1, 2020 and May 17, 2021 to apply to the GSoC program.

If you have any doubts, please don’t hesitate to contact the GNOME GSoC Admins on Discourse or https://chat.gnome.org/channel/outreach

Felipe Borges: Delivering osinfo-db updates automatically for Flatpak users

17 de Dezembro de 2020, 11:11, por Planeta GNOME Brasil - 0sem comentários ainda

If you are familiar with GNOME Boxes internals you are aware that our secret sauce is libosinfo. It does the OS image detection and provides us with a database of devices, preferences, and compatibility for the operating systems we support.

In the world of traditional package management tools, osinfo-db is the package responsible for delivering updates about new operating system’s releases, fixes, and improvements that Boxes will consume. So whenever you wonder why the newest EndlessOS or the newest Debian release isn’t listed in the Boxes download section, it is likely that osinfo-db is outdated.

The pipeline from upstream -> distros -> to users is extremely valuable for apps and libraries. It is our “integration testing” phase. But for data-only packages like osinfo-db, we noticed that most users’ complains are regarding the package being outdated. We rarely see bugs introduced by osinfo-db updates. The very separation of the dataset (osinfo-db) and the library (libosinfo) is the reason for us to feel confident about contentiously delivering the dataset directly to our users.

For this reason, Flatpak users of GNOME Boxes will now benefit from the OsinfoDb Flatpak extension. It allows us to deliver osinfo-db updates direclty to users without updating the entire Boxes Flatpak. If you are receiving automatic updates in GNOME Software, the osinfo-db update is seamlessly.

Boxes still bundles its own osinfo-db data for those that don’t want to consume the extension. This will be updated whenever the Boxes Flatpak is updated, so expect it in a slower cadence.

Nothing is required from users to transition to this. Flatpak will pull the extension for you once you update Boxes.
