In the previous parts of this series (part 1, part 2, part 3, part 4) we looked at how power works within GNOME, and what this means for people wanting to have an impact in the project. An important takeaway was that the most effective way to do that is to get acquainted with the project’s ethos and values, and then working towards things that align with these.
However, you have to start somewhere. In practical terms, how do you do that?
Perhaps you have lots of big ideas and futuristic plans for the project, and your first impulse is to start working on those. However, if you’re a new contributor keep the following in mind:
There’s often important context and history around a subject that you may not be aware of yet. Having this context inform your ideas generally makes them better and easier for others to get on board with.
It’s important to build trust with the community. People are likely to be skeptical of super ambitious proposals from people they don’t know yet, and who may not stick around long term.
Learning to effectively advertise your ideas and get buy-in from various people takes time. This goes especially for bigger changes, e.g. ones which impact many different modules.
Ideally the size of the things you propose should be proportionate to how well-integrated into the community you are. Trying to do a complete rewrite of GNOME Shell as your first contribution is likely not going to result in much. Something simple and self-contained, such as an individual view in an app is usually a good place to get started.
This doesn’t mean newcomers shouldn’t dream big (I certainly did). However, realistically you’ll be more successful starting with small tasks and working your way up to larger ones as you gain a better understanding of the project’s history, the underlying technologies, and the interests of various stakeholders.
What exactly to do first depends on the area you’re planning on contributing to. I’ll keep this focused on the areas I’m personally most involved with and which have the most immediate impact on the product, but of course there are lots of other great ways to get involved, such as documentation, engagement, and localization.
For programming there is a newcomer guide that guides you towards your first merge request. Check out the developer portal for documentation and other resources. Beyond the newcomer projects you can of course also just look at open newcomer (and non-newcomer) issues in specific projects written in your language of choice on GNOME Gitlab.
For design it’s easiest to just reach out to the design team and ask them to help you find a good first task. Ideally you’d start working with developers on something real as soon as possible, and the design team usually know what urgently needs design at the moment.
Of course, if you’re a developer there’s also the option of starting out by writing your own third-party apps, rather than contributing to existing ones. A great third-party app is a very valuable contribution to the project, and with GNOME Circle there is a direct path to GNOME Foundation membership.
Becoming a part of the community is not just about doing work. It’s also about generally being active in community spaces, whether that’s hanging out in chat rooms, interacting with fellow contributors on social media, or going to physical meetups, hackfests, and conferences.
Some starting points for that:
Join the Matrix channels for the projects you’re interested in. Depending on the channel it’s possible that not much is going on at the moment, but this tends to be seasonal. Especially app-specific channels can fluctuate wildly in activity depending on how many people are working on the app right now.
Join some of the larger “general” GNOME Matrix channels for project-wide discussions and community stuff.
Reach out to people who work on things you want to get into and ask them about ways to get involved more closely. Of course it’s important to be respectful of people’s time, but most people I know are happy to answer a few quick questions once in a while.
Come to GUADEC, LAS, or other real-world meetups. Meeting other contributors face to face is one of the best ways to truly become part of the community, and it’s a lot of fun! Once it’s possible again COVID-wise, I highly recommend attending an in-person event.
Doing the Work
If you follow the above steps and contribute on a regular basis for a few months you’ll find that you’ve organically become a part of the project.
People will start to ask your opinion about what they’re currently doing, or for you to review their work. You’ll probably specialize in one or a few areas, and maybe become the go-to person for those things. Before you know it someone will ask you if you’re coming to the next hackfest, if you’ve already got your Foundation membership, or if you’d like to become co-maintainer of a module.
If you’ve joined the project with big ideas, this is the point where you can really start moving towards making those ideas a reality. Of course, making big changes isn’t easy even as a long-time contributor. Depending on the scope of an initiative it can take months or years to get something done (for example, our adaptive apps initiative started in 2018 and is still ongoing).
However, as an experienced contributor you have the technical, social, and ideological context to push for your ideas in a way that aligns with other people’s goals and motivations. This not only makes it less likely that your plans will face opposition, but if you’re doing it right it people will join you and help make it happen.
This concludes my 5-part series on how power works in the GNOME community, and how to get your pet feature implemented. Sorry to disappoint if you thought it was going to be quick and easy :)
On the plus side though, it’s a chance to be part of this amazing community. The friends you make along the way are truly worth it!
While this is the end of the series as I originally planned it, there are definitely areas it doesn’t cover and that I might write about in the future. If there are specific topics you’d be interested in, feel free to leave a comment.
In the first three parts of this series (part 1, part 2, part 3) we looked at how power works within GNOME and what that means for getting things done. We got to the point that to make things happen you (or someone you’ve hired) need to become a trusted member of the community, which requires understanding the project’s ethos.
In this post we’ll go over that ethos, both in terms of high level values, and what those translate to in more practical terms.
Values and Principles
GNOME is a very principled project, and there’s a fair amount of writing on this topic already.
To give you an overview though, here’s my personal bullet point summary. It follows the same structure as the development process laid out in part 2 based on what areas specific values and ideas apply to. It’s not meant to be comprehensive, but rather give you an idea of the way people inside the project think.
Base motivations that inform everything we do.
We believe in software freedom as an inclusive, accountable model for producing technology in the commons.
Our software is built to be usable by everyone. We care deeply about user experience, accessibility, internationalization, and support for a diverse range of hardware.
Software should be structurally and aesthetically elegant, both in terms of underlying technology and user interface.
What kinds of things we think are worth pursuing, and (just as important) what kinds of things should be avoided.
Third-party apps are the best abstraction to extend the core system with additional functionality. This is why we put a huge amount of work into empowering third party app developers to build more and better apps.
Every preference has a cost, and this cost rises exponentially as you add more of them. This is why we avoid preferences as much as possible, and focus on fixing the underlying problems instead.
Similarly, there is a direct relationship between how vertically integrated a product is and how cohesive you can make it. Every unnecessary variable you eliminate across the stack frees up time and energy, and creates opportunities for features you couldn’t otherwise build.
People’s attention is precious. We pride ourselves in being distraction free.
Useful rules of thumb around how we go about making things.
We don’t do hacks. Rather than working around a problem at the wrong layer of abstraction, we believe in going to the root of the problem and fixing it for everyone, even if that means digging into lower layers (and ends up being far more difficult as a result).
We see design holistically, rather than as an isolated thing the design team does. It’s not just about functionality and aesthetics, but also underlying technology, and what to build in the first place. Even if you’re not contributing on the design team, developing an affinity for design will make you a more effective contributor.
Looking at relevant art is important, but simply copying the competition doesn’t usually produce great results. We have a proud history of inventing new paradigms that are better than the status quo.
As a general rule, start from the user experience you want and then go about building the technology necessary to create it, not the other way around. However: This is not an excuse for bad engineering or pursuing ideas that are conceptually impossible (e.g. multi-protocol chat clients).
Defer to the Expert. Everyone has different areas of expertise, such as user experience, security, accessibility, performance, or localization. Listen to the people most experienced in a given domain.
Design is all about trade-offs. Be wary of hard and fast rules that only look at one part of a problem (e.g. “vertical space is at a premium, therefore…”), and instead try to balance various concerns in a way that works well overall.
Some of the above principles are quite abstract, so what do they translate to when actually building software day to day? Here are some examples of how they apply to real-world questions.
App developers should do their own packaging. It’s the only way to do it sustainably at scale.
The “traditional desktop” is dead, and it’s not coming back (Note: I’m talking about Windows 95 era UI patterns here, not desktop vs. mobile). Instead of trying to bring back old concepts like menu bars or status icons, invent something better from first principles.
System-wide theming is a broken idea. If you don’t like the way apps look, contribute to them directly (or to the platform style).
Shell extensions are always going to be a niche thing. If you want to have real impact your time is better invested working on apps or GNOME Shell itself.
“Filling the available space” is rarely a good goal by itself, and an easy way to design yourself into a corner.
All of the above is of course my personal perception, and you’ll find variations on these ideas depending on who you talk to. However, in my experience most of them are shared fairly consistently by people across the community, especially given our informal structure.
Now that we’ve covered how things get done, by whom, and why, you’re in a great position to start making your mark. In the next part of this series we’ll look at practical first steps for contributing.
In parts 1 and 2 of the series we looked at how different groups inside the GNOME community work together to get things done. In this post we’ll look at what that means for people wanting to push for their personal agenda, e.g. getting a specific feature implemented or bug fixed.
Implicit in the theoretical question how power works in GNOME is often a more practical one: How can I get access to it? How can I exercise power to get something I want?
At a high level that’s very easy to answer: You either do the work yourself, or you convince someone else to do it.
Do It Yourself
If you’re the person working on something you have a ton of power over that thing. Designing and building software is in essence an endless stream of decisions. The more work you do, the more of those decisions you end up making.
Of course, in practice it’s not quite that simple. User-visible features need design reviews, and unless you’re the sole maintainer of a project you also need to go through code reviews to get your changes merged. As a designer, most things you design need to be implemented by someone else, so you have to convince them to do that.
However, it’s definitely possible to have a huge impact simply by doing a lot of work, and not only because of all the decisions you end up making directly as you implement things. If you contribute regularly to a module you’ll eventually end up reviewing other people’s work, and generally being asked for your opinion on topics you’re knowledgeable about.
Making Your Case
If you can’t, don’t want to, or don’t have time to do the work yourself, you’ll need to find someone else to do it for you. This is obviously a difficult task, because you’re essentially trying to convince people to work for you for free.
Some general tips for this:
Get an idea of what kinds of things the people you’re trying to convince are interested in, e.g. technologies they like and types of problems they care about.
Make the case that your idea fits into something they are already working on, or will help them reach goals they are already pursuing.
Generally speaking, you’ll have a much better chance with new-ish contributors. They tend to be less overworked since they don’t maintain as many mission-critical modules.
Realistically, unless your idea is very small in scope, or exactly what someone was already looking for, this strategy is not very likely to succeed. Most contributors, volunteer or paid, already have a huge backlog of their own to work through. There are only so many hours in the day, and GtkTimeMachine is not yet a thing :)
However, the chances are not zero either, and it’s always possible that even if your idea isn’t picked up right away it will spark something later on, or influence future discussions.
Paying Someone Else
You can of course also convince people to work on something you want by hiring them (radical, I know!).
There are plenty of very talented people in the GNOME community who do contract development, from individuals to fairly large consultancies. You can also hire someone from outside the project, but then they will have to build trust with the community first, which is non-trivial overhead. In most cases, hiring existing contributors is orders of magnitude more effective than people who aren’t already a part of the project.
How to hire people to implement things for you is out of scope for this series, but if you’d like advice on it feel free to contact me or leave a comment. If there’s enough interest I might write about it in the future.
All of that said, if the thing you want doesn’t align with the ethos of the project it’s going to be difficult regardless of which strategy you go with. This is why familiarizing yourself with that ethos is important if you want to make your mark on the project. To help with that we’ll go over GNOME’s principles and values in the next part of this series.
In part 1 of this series we looked at some common misconceptions about how power works inside the GNOME project and went over the roles and responsibilites of various sub-groups.
With that in place, let’s look at how of a feature (or app, redesign, or other product initiative) goes from idea to reality.
At the base of everything are the motivations for why we embark on new product initiatives. These are our shared values, beliefs, and goals, rooted in GNOME’s history and culture. They include goals like making the system more approachable or empowering third party developers, as well as non-goals, such as distracting people or introducing unnecessary complexity.
Since people across the project generally already agree on these it’s not something we talk about much day-to-day, but it informs everything we do.
At any given moment there are potentially hundreds of equally important things people working on GNOME could do to further the project’s goals. How do we choose what to work on when nobody is in charge?
This often depends on relatively hard to predict internal and external factors, such as
A volunteer taking a personal interest in solving a problem and getting others excited about it (e.g. Alexander Mikhaylenko’s multi-year quest for better 1-1 touchpad gestures)
A company giving their developers work time to focus on getting a specific feature done upstream (e.g. Endless with the customizable app grid)
The design team coming up with something and convincing developers to make it happen (e.g. the Shell dialog redesign in 3.36)
A technological shift presenting a rare opportunity to get a long-desired feature in (e.g. the Libadwaita stylesheet refresh enabling recoloring)
For larger efforts, momentum is key: If people see exciting developments in an area they’ll want to get involved and help make it even better, resulting in a virtuous cycle. A recent example of this was GNOME 40, where lots of contributors who don’t usually do much GNOME Shell UI work pitched in during the last few weeks of the cycle to get it over the line.
If something touches more than a handful of modules (e.g. the app menu migration), the typical approach is to start a formal “Initiative”: This is basically a Gitlab issue with a checklist of all affected modules and information on how people can help. Any contributor can start an initiative, but it’s of course not guaranteed that others will be interested in helping with it and there are plenty of stalled or slow-moving ones alongside the success stories.
If a new app or feature is user-facing, the first step towards making it happen is to figure out the user experience we’re aiming for. This means that at some point before starting implementation the designers need to work through the problem, formulate goals, look at relevant art, and propose a way forward (often in the form of mockups). This usually involves a bunch of iterations, conversations with various stakeholders, and depending on the scale of the initiative, user research.
If the feature is not user-facing but has non-trivial technical implications (e.g. new dependencies) it’s good to check with some experienced developers or the release team whether it fits into the GNOME stack from a technical point of view.
Once there is a more or less agreed-upon design direction, the implementation can start. Depending on the size and scope of the feature there are likely additional design or implementation questions that require input from different people throughout the process.
When the feature starts getting to the point where it can be tested by others it gets more thorough design reviews (if it’s user facing), before finally being submitted for code review by the module’s maintainers. Once the maintainers are happy with the code, they merge it into the project’s main branch.
In the next installment we’ll look at what this power structure and development process mean for individual contributors wanting to work towards a specific goal, such as getting their pet bug fixed or feature implemented.
People new to the GNOME community often have a hard time understanding how we set goals, make decisions, assume responsibility, prioritize tasks, and so on. In short: They wonder where the power is.
When you don’t know how something works it’s natural to come up with a plausible story based on the available information. For example, some people intuitively assume that since our product is similar in function and appearance to those made by the Apples and Microsofts of the world, we must also be organized in a similar way.
This leads them to think that GNOME is developed by a centralized company with a hierarchical structure, where developers are assigned tasks by their manager, based on a roadmap set by higher management, with a marketing department coordinating public-facing messaging, and so on. Basically, they think we’re a tech company.
This in turn leads to things like
People making customer service style complaints, like they would to a company whose product they bought
General confusion around how resources are allocated (“Why are they working on X when they don’t even have Y?”)
Blaming/praising the GNOME Foundation for specific things to do with the product
If you’ve been around the community for a while you know that this view of the project bears no resemblance to how things actually work. However, given how complex the reality is it’s not surprising that some people have these misconceptions.
To understand how things are really done we need to examine the various groups involved in making GNOME, and how they interact.
The GNOME Foundation is a US-based non-profit that owns the GNOME trademark, hosts our Gitlab and other infrastructure, organizes conferences, and employs one full-time GTK developer. This means that beyond setting priorities for said GTK developer, it has little to no influence on development.
The people actually making the product are either volunteers (and thus answer to nobody), or work for one of about a dozen companies employing people to work on various parts of GNOME. All of these companies have different interests and areas of focus depending on how they use GNOME, and tend to contribute accordingly.
In practice the line between “employed” contributor and volunteer can be quite blurry, as many contributors are paid to work on some specific things but also additionally contribute to other parts of GNOME in their free time.
Each module (e.g. app, library, or system component) has one or more maintainers. They are responsible for reviewing proposed changes, making releases, and generally managing the project.
In theory the individual maintainers of each module have more or less absolute power over those modules. They can merge any changes to the code, add and remove features, change the user interface, etc.
However, in practice maintainers rarely make non-trivial changes without consulting/communicating with other stakeholders across the project, for example the design team on things related to the user experience, the maintainers of other modules affected by a change, or the release team if dependencies change.
The release team is responsible for coordinating the release of the entire suite of GNOME software as a single coherent product.
In addition to getting out two major releases every year (plus various point releases) they also curate what is and isn’t part of the core set of GNOME software, take care of the GNOME Flatpak runtimes, manage dependencies, fix build failures, and other related tasks.
The Release Team has a lot of power in the sense that they literally decide what is and isn’t part of GNOME. They can add and remove apps from the core set, and set system-wide default settings. However, they do not actually develop or maintain most of the modules, so the degree to which they can concretely impact the product is limited.
Perhaps somewhat unusually for a free software project GNOME has a very active and well-respected design team (If I do say so myself :P). Anything related to the user experience is their purview, and in theory they have final say.
This includes most major product initiatives, such as introducing new apps or features, redesigning existing ones, the visual design of apps and system, design patterns and guidelines, and more.
However: There is nothing forcing developers to follow design team guidance. The design team’s power lies primarily in people trusting them to make the right decisions, and working with them to implement their designs.
How do things get done then?
No one person or group ultimately has much power over the direction of the project by themselves. Any major initiative requires people from multiple groups to work together.
This collaboration requires, above all, mutual trust on a number of levels:
Trust in the abilities of people from other teams, especially when it’s not your area of expertise
Trust that other people also embody the project’s values
Trust that people care about GNOME first and foremost (as opposed to, say, their employer’s interests)
Trust that people are in it for the long run (rather than just trying to quickly land something and then disappear)
This atmosphere of trust across the project allows for surprisingly smooth and efficient collaboration across dozens of modules and hundreds of contributors, despite there being little direct communication between most participants.
This concludes the first part of the series. In part 2 we’ll look at the various stages of how a feature is developed from conception to shipping.
This is Part 2 of a series on what’s wrong with the free desktop app ecosystem and how we can fix it, based on the talk Jordan Petridis and I gave at LAS 2019 in Barcelona.
In Part 1 we looked at all the different elements making up a platform, and found that there is only one “complete” platform in the free software desktop world at the moment. This is because desktops control the developer platforms, while packaging and system integration is managed by separate communities, the distributions, for historical reasons. This additional layer of middlemen is a key reason why we don’t have real platforms.
Power to the Makers
The problems outlined in Part 1 are of coursenot new, and people havebeen workingon solutions to them for a long time. Some of these solutions have really started to come together over the last few years, empowering the people making the software to distribute it directly to the people using it.
Thanks to the work of many amazing people in our community you can now develop an app in GNOME Builder, submit it to Flathub, get it reviewed, and have it available for people to install right away. Once it’s on there you can also update it on a schedule you control. No more waiting 6 months for the next distribution release!
But though this is all very awesome, Flatpak is unfortunately not a complete solution to the platform conundrum discussed earlier in this series.
Flatpak is Not Enough
Flatpak does solve a number of the issues around app distribution very elegantly, because app developers do their own packaging, and control their release schedule. It’s also a unified package format that works across different host systems, and the Flatpak runtimes are clearly defined development targets to do QA against.
But that doesn’t magically fix all our problems. The two elephants in the room are
The Host still matters: Flatpak only solves part of the issues with distro packaged apps
Downstream drama: Flatpak does not address the conflicts between desktops and distributions
1. The Host Still Matters
Even with Flatpak there are still some unpredictable variables on the host system which affect app developers. On the technical side a number of things can go wrong, from an outdated Flatpak version (which can mean some Portals apps rely on may be missing), to missing/incompatible system APIs such as password storage, calendar, or address book.
These things can lead to applications not working properly, or at all. For example, this is why new versions of GNOME Contacts cannot access any contacts on Debian 10, why recent GNOME Calendar cannot access any calendars on Ubuntu 18.04, or why Fractal doesn’t remember your password across restarts on some non-GNOME environments.
There are also user-facing integration points where applications interface with the system. These include things like notifications, the application menu, search providers, the old systray, and the design patterns used in individual apps.
For example, when the system UI or design guidelines change, applications follow the platform and change their UI accordingly. This means if you install newer apps on an older system, there are going to be weird edge cases. For example, if you install new apps on Debian 10 you get a confusing mix of the old and new application menu paradigms because the design guidelines were changed with GNOME 3.32 (early 2019).
Flatpak also applies the host GTK stylesheet and icon set to apps. This means that if the host distribution overrides the system stylesheet, Flatpak will happily apply random, never-tested CSS to every app. Obviously this leads to lots of issues, ranging from ugly but relatively harmless glitches to real usability issues, such as illegible text on buttons. For more background on this particular issue, see this blog post.
Some of these issues could be fixed with more standardization, changes to Flatpak, or new portals. However, fundamentally, in order to be a real platform you need a clearly defined environment to develop and test for. Flatpak alone is not enough to achieve that.
Just like “write once, run everywhere” is always an illusion, it’s never going to be possible to completely split apps from the OS. You always need app developers to do some extra work to support different environments, and currently every distribution represents yet another extra environment to support.
2. Downstream Drama
Flatpak does not completely solve the issues app developers face in shipping their software, because these can not be isolated from the ones desktop developers face. In order to fix the app developer story we need real platforms. In order to get those we need to resolve the desktop/distribution dilemma.
The issues here roughly match the ones with traditional distribution packaging mentioned in Part 1, and can be grouped into three broad categories:
Structural issues inherent to having distributions and desktops be separate projects.
Fragmentation issues because we have multiple of everything so there’s duplication and/or bad abstraction layers.
Configuration issues, primarily around settings and other defaults, which have to be set at the distribution level but affect the user experience.
One of the biggest structural issues is distribution release schedules not being aligned with the upstream one (or between different distributions). GNOME releases every 6 months, but distributions can take anywhere from a few weeks to several years to ship these releases.
This category also includes distributions overriding upstream decisions around system UX, as well as theming/branding issues, due to problematic downstream incentives. This means there is no clear platform visual identity developers can target.
For example, Ubuntu 18.04 (the current LTS) ships with GNOME 3.28 (from March 2018), includes significant changes to system UX and APIs (e.g. Unity-style dock, desktop icons, systray extension), and ships a branded stylesheet that breaks even in core applications.
Having multiple implementations of everything means we either need do tons of duplicate work, or try to abstract over the different implementations.
On one end of the spectrum there are OS installers: There is no GNOME installer, so every distribution builds their own. Unfortunately, most of these installers are not very good, and don’t integrate well with the rest of the desktop experience (e.g. they use different design patterns than the OS itself). This can be either due to a lack of resources (e.g. not every downstream has their own GNOME designers), or because different distributions have specific downstream goals and motivations (e.g. Fedora and RHEL share an installer, which introduces lots of complexity).
In other areas we have the opposite problem, because we’re trying to abstract over the fragmentation with a single component. For example, PackageKit is meant to abstract over different package formats, but in practice it only works for a handful of them, and even for those it’s often buggy. The PackageKit maintainers have officially given up on this approach.
This includes the default apps, the fonts shipped with the system by default, the terminal shell and prompt, and the UX around things like Plymouth. All of these things are usually configured at the distribution level and are therefore often not great, because these choices need to be made in concert with the rest of the platform UX.
Given the constraint of there being multiple different desktops projects and technology stacks (and the host still mattering), we’ll never have a single “Linux” or “FreeDesktop” platform. We could have one platform per desktop though.
From an app developer point of view, testing for GNOME, KDE, and elementary isn’t as nice as testing only for a single platform, but it’s not impossible. However, testing for Debian, Fedora, multiple Ubuntu releases, OpenSUSE, Arch, Endless, and dozens more is not and never will be feasible, even with Flatpak. Multiple different distributions, even ones that ship the same desktop environment, don’t add up to a platform. But exactly that is what we need, one way or another.
The question is, how do we get there?
The Nuclear Option
When we look at it from a Flatpak context, the solution seems obvious. Flatpak is solving the middleman problem for app developers by circumventing the distributions and providing a direct channel between developers and end users. What if we could do the same thing for the OS itself?
Of course the situation isn’t exactly the same, so what would that mean in practice?
With Flatpak runtimes there is no extra “distribution” abstraction layer. There are no Debian or Fedora runtimes, just GNOME and KDE, because those are the technology stacks app developers target.
These runtimes are already more or less full-fledged distributions which are controlled by the desktops, we’re just not using them as such. The Freedesktop SDK (which most runtimes are based on) is not based in any distro, but built directly from upstream sources using Buildstream as the build tool, and it already has most of the things you need to make a basic operating system.
There is an early-stage effort to make bootable nightly GNOME OS images for development/testing, built on top of the Freedesktop SDK. From there it wouldn’t be a huge leap to actually make an independent, consumer-facing platform OS for GNOME (and KDE, and other platforms).
However, though this is likely to become a very attractive solution in the future, there are a number of hurdles to be overcome:
An OS needs an installer, OS updates, a Plymouth theme, etc. All of these are being worked on for the nightly GNOME OS images, but are not quite there yet.
A “real” OS needs a dedicated group of people doing things like release management, security tracking, and QA. These are being done to some degree for the Flatpak runtimes, but a consumer OS would need more manpower.
It’s an OSTree-based immutable system, which means there is no traditional package management. Apps are installed via Flatpak, and server/developer workflows need to happen in containers. Though projects like Silverblue’s toolbox have come a long way over the past few years, there’s still work to be done before immutable OSes can painlessly replace systems with old-school package managers for all use cases.
It takes time to start a new operating system from scratch, especially when it’s using cutting-edge technology. So while things like GNOME OS could be amazing in the longer-term future, it’s likely going to take a few more years before this becomes a viable alternative.
Squaring the Circle
What could we do within the constraints of the technology, ecosystem, and communities we have today, then? If we can’t go around distributions with a platform OS, the only alternative is to meld the distributions into a meta platform OS.
Technically there’s nothing stopping a group of separate distributions from acting more or less like a unified platform OS together. It would require extraordinary discipline and compromise on all sides (admittedly not things our communities are usually known for), but given how important it is that we fix this problem, it’s at least worth thinking about.
To get an idea what this could look like in practice, let’s think through some of the specific issues mentioned earlier:
Release Schedule: This is probably among the thorniest issues since release cycles vary wildly in length and structure, and changing them is very difficult. It’s not unimaginable that at least some progress could be made here though. For example, GNOME could have long term support releases every 2-3 years for “stable” distributions like RHEL and Ubuntu LTS. Distributions could then agree to either be on the regular 6 month schedule, or the 2 year “LTS” schedule. Alternatively, all distributions could find a single compromise schedule that can work for everyone (e.g. maybe one release per year, like mobile operating systems do).
Theming/Branding: Some distributions want ways to customize the OS experience such that their system looks recognizably different from others. This is not necessarily a problem, as long as this is done using APIs that are supported and intended to be used in this way (which unfortunately is currently not happening in many cases).
Creating more branding opportunities which do not break APIs which apps rely upon (especially third party apps shipped via Flatpak), is certainly possible and there have been discussions in this direction (e.g. GTK accent colors). Whether distributions would limit themselves to these APIs once they exist is of course an open question, but at least there is a ongoing dialog about this.
System UX/API Changes: Some distributions make significant changes to the core system, which fragments the visual identity of the platform at best, and severely damages the app ecosystem at worst. This includes things like adding a permanent dock, icons on the desktop, re-enabling the systray, or a “dark mode” setting which just changes the system stylesheet from under apps.
The solution here is simple in theory: If you think a change to the system UX is needed to fix a specific problem, don’t just patch it downstream, but instead help to address the actual underlying issue (We already touched on this in Part 1). For example, if you find that new users are confused by the empty desktop at startup, don’t just ship an extension that completely breaks the structure of the shell. Bring the problem to the upstream designers and developers, figure out a solution together, and help implement it upstream.
In practice it’s not always that easy, but a lot can be done by simply adopting an upstream-first UX mindset. It can take a while to get used to, especially for companies with more, uh, “traditional” internal processes, but it’s definitely possible seeing as it’s working well for Red Hat and Purism, for example.
OS Installer: It may not be doable to have a single code base, but we could definitely share at least the design (and possibly some UI code) for the installers used across distributions. A cross-distribution initiative for nice, native GNOME installers across the major distributions would probably not be easy logistically, but is not unimaginable.
Software Installation & Updates: GNOME Software and PackageKit’s “abstract across distros” strategy has clearly failed, and we need a new approach here. For applications there is a relatively easy solution: Distributions stop packaging apps, and work together on a common repository of developer-submitted Flatpaks (e.g. something like Flathub). We’d need to work out how this common solution can accommodate various distribution policies around e.g. proprietary software, but this seems very doable and most of it already exists in Flathub.
The resources currently going into repackaging every app for every distribution could be pooled to review the apps submitted by developers to the common Flatpak repository.
Seeing as most distributions are not (yet) image-based like e.g. Silverblue or Endless, we would still also need a way to update the packages that make up the core system. For this there’s probably no way around backend duplication.
System Default Configuration: Making progress in this area is likely not too difficult comparatively. The main thing we’d need is better coordination between the various parties needed to synchronize these things better (which is of course easier said than done). Having some kind of common forum where the upstream design and release team, as well as people in charge of major distributions can discuss and standardize defaults across the entire ecosystem might work for that.
The Bottom Line
If we want a future with real platforms we can either go around the distributions or have them all work together (or potentially both), but one way or another we need to vertically integrate.
Neither path is straightforward or easy, and there’s a huge amount of work ahead either way. However, the first and most important step is acknowledging that this problem exists, and that we need to radically change our approach if we’re serious about building attractive app ecosystems.
The good news is that many people across different projects are already working towards enabling this future. We hope that you’ll join us.
In our community there is this idea that “Linux” is the third platform next to Windows and macOS. It’s closely connected to things like the “year of the Linux desktop”, and can be seen in the language around things like Flatpak, which bills itself as “The Future of Apps on Linux” and the Linux App Summit, which is “designed to accelerate the growth of the Linux application ecosystem”.
But what does that actually mean? What does a healthy app ecosystem look like? And why don’t we have one?
I think the core of the problem is actually the layer below that: Before we can have healthy ecosystems, we need healthy platforms to build them on.
What is a Platform?
The word “platform” is often used without a clear definition of what exactly that entails. If we look at other successful platforms there are a ton of different things enabling their success, which are easy to miss when you just look at the surface.
On the developer side you need an operating system developers can use to make apps. You also need a developer SDK and tooling which are integrated with the operating system. You need developer documentation, tutorials, etc. so people can learn how to develop for the platform. And of course once the apps are built there needs to be an app store to submit them to.
Developers can’t make great apps all by themselves, for that you also need designers. Designers need tools to mock up and prototype apps, platform UI patterns for things like layout and navigation, so every app doesn’t have to reinvent the wheel, and a visual design language so designers can make their app fit in with the rest of the system visually. You also need Human Interface Guidelines documenting all of the above, as well as tutorials and other educational resources to help people learn to design for the platform.
On the end user side you need a consumer OS with an integrated app store, where people can get the great apps developers make. The consumer OS can be the same as the developer OS, but doesn’t have to be (e.g. it isn’t for Android or iOS). You also need a way for people to get help/support when they have problems with their system (whether that’s physical stores, a help website, or just easily google-able Stackoverflow questions).
That’s a lot of different things, but we can group them into four major pieces which are needed in order for something to be a real platform:
So if we look at the free software world, where are the platforms?
Linux is a kernel, which can be used to build OSes, which can be used to build platforms. Some people (e.g. Google with Android) have done so, but a kernel by itself doesn’t have any of the four things outlined above, and therefore is not a platform.
What about “Desktop Linux”, which is what people usually mean when they say “Linux”? The problem is that this term doesn’t have a clear definition. You could take it to mean “FreeDesktop.org”, but that also doesn’t come close to being a platform. FreeDesktop is a set of standards that can be used to build platforms (and/or ensure some level of compatibility between different platforms). Endorsement of a single platform or set of technologies goes directly against FreeDesktop’s aims, and as such it should only be thought of as the common building blocks platforms might share.
What about distributions? Ubuntu is one of the most popular ones, and unlike others it has its own app store. It still isn’t a platform though, because it doesn’t have the most critical pieces: a developer SDK/technology stack, and a design language.
Other distributions are in a similar but worse position because they don’t have an app store.
GNOME is the most popular desktop stack, and it does have an SDK and design language. However, it only sort of has an app store (because GNOME people work on Flathub), and it doesn’t have an OS. Many distributions ship GNOME, but they are all different in various ways (more on this later), so they don’t provide a unified development target.
Interestingly, the only project which currently has all the pieces is elementary. It has an OS, an SDK, a HIG, and an app store to submit apps to. The OS is largely Ubuntu and the technology stack largely GNOME, but it develops its own desktop and apps on top of that, and does the integration work to make it into a complete consumer product.
This begs the question, why is elementary the only one?
The Means of Distribution
The reasons for this are largely historical. In the early days, free software desktops were a bunch of independently developed components. They were not necessarily designed for each other, or well integrated. This meant in order to have a usable system, someone needed to curate these components and assemble them into an operating system: The first distributions were born.
Over the last decades this landscape has changed drastically, however. While GNOME 1 was a set of loosely coupled components, GNOME 2 was already much more cohesive and GNOME 3 is now essentially an integrated product. The shell, core apps, and underlying technologies are all designed with each other in mind, and provide a complete OS experience.
Desktops like GNOME have expanded their scope to cover most of the responsibilities of platforms, and are in effect platforms now, minus the OS part. They have a very clear vision of how the system should work, and app developers target them directly.
The elementary project has taken this development to its logical end point, and made its own vertically integrated OS and app store. This is why it’s the only “real” platform in the free software space at the moment.
Distributions, on the other hand, have not really changed since the 90s. They still do integration work on desktop components, package system and applications, set defaults, and make UX decisions. They still operate as if they’re making a product from independent components, even though the actual product work is happening at the desktop layer now.
This disconnect has led to tensions in many areas, which affect both the quality of the system user experience, and the health of the app ecosystem.
What’s interesting about this situation is that desktop developers are now in the same situation app developers have always been in. Unlike desktops, apps have always been complete products. Because of this they have always suffered from the fragmentation and disconnect between developers and users introduced by distribution packaging.
Grievances with the distribution model, which affect both app and desktop developers, include:
Release schedule: Developers don’t have control over the pace at which people get updates to their software. For apps this can mean people still get old versions of software with issues that were fixed upstream years ago. For desktops it’s even worse, because it means app developers don’t know what version of the platform to target, especially since this can vary wildly (some distributions release every 6 months, others every 2+ years).
Packaging errors: Distribution packaging is prone to errors because individual packagers are overloaded (often maintaining dozens or hundreds of packages), and don’t know the software as well as the developers.
Overriding upstream decisions: When distributions disagree with upstream decisions, they sometimes keep old version of software, or apply downstream patches that override the author’s intentions. This is very frustrating if you’re an app developer, because users never experience your app as you intended it to be. However, similar to the release schedule issue, it’s even worse when it happens to the core system, because it fragments the platform for app developers.
Distro Theming: App developers test with the platform stylesheet and icons, so when distributions change these it can break applications in highly visible ways (invisible widgets, unreadable text, wrong icon metaphors). This is especially bad for third party apps, which get little or no testing from the downstream stylesheet developers. This blog post explains the issue in more detail.
The Wrong Incentives
The reason for a lot of these issues is the incentives on the distribution side. Distributions are shipping software directly to end users, so it’s very tempting to solve any issues they find downstream and just ship them directly. But because the distributions don’t actually develop the software this leads to a number of other problems:
Perpetual rebasing: Any change that isn’t upstreamed needs to be rebased on every future version of the upstream software.
Incoherent user experience: Downstream solutions to UX problems are often simplistic and don’t fix the entire issue, because they don’t have the development resources for a proper fix. This leads to awkward half-redesigns, which aren’t as polished or thought-through as the original design.
Ecosystem fragmentation: Every downstream change adds yet another variable app developers need to test for. The more distributions do it, the worse it gets.
The Endless OS shell is a great example of this. They started out with vanilla GNOME Shell, but then added ever more downstream patches in order to address issues found in in-house usability tests. This means that they end up having to do huge rebasesevery release, which is a lot of work. At the same time, the issues that prompted the changes do not get fixed upstream (Endless have recently changed their strategy and are working upstream much more now, so hopefully this will get better in the future).
This situation is clearly bad for everyone involved: Distributions spend a ton of resources rebasing their patches forever, app developers don’t have a clear target, and end users get a sub-par experience.
So, what could we do to improve this? We’ll discuss that in part 2 of this series :)
