P is for…

Wednesday, October 5th, 2011

It’s a perennial pleasure to pick pertinent and/or pithy placeholder names for Ubuntu releases. At least, I like to think of them as pertinent and/or pithy. I’ve had diverse feedback, shall we say. Nevertheless, it’s now a tradition, and it’s a pressing priority as we approach the release of Oneiric.

So, what will be our mascot for 12.04 LTS?

The letter P is pretty perfect. It’s also plentiful – my inbox has been rather full of suggestions – and we have options ranging from pacific to purposeful, via puckish and prudent. We’ll steer clear of the posh and the poncey, much as some would revel in the Portentious Palomino or the Principled Paca, those aren’t the winning names. Having spent the last six months elucidating the meaning of “oneiric” I think it might also be worth skipping the parenthetical or paralogical options too; so sadly I had to exclude the Perspicacious Panda and Porangi Packhorse (though being an LTS, that Packhorse was a near thing).

Being generally of a cheerful nature, I thought we’d avoid the Predatory Panther and Primeval Possum. Neither sounds like great company for a seven year journey, really. Same goes for the Peccable Peccary, Pawky Python and Perfidious Puku. So many bullets to dodge round here!

We’re looking for something phonetic, something plausible and something peaceful too. We’ll avoid the petulant, the pestilent, the phlegmy (phooey!), the parochial, the palliative and the psychotic. We’re aiming for mildly prophetic, and somewhat potent, without wanting to be all pedantic and particular. Phew.

So, what might work?

There are lots of lovely candidates. I have a fondness for phat. The Phat Platypus has a can-do kind of ring to it, but I don’t think it’ll fly.

I also like punchy and perky (the Perky Penguin is a nice nostalgic option) and persistent (better than permanent, peerless or penultimate) and playful and plucky and poised. Others like prescient and peaceable and pervasive (!) and pivotal. Pukka rings a nice old-world bell, but it’s possibly pejorative.

As you can see, it’s been something of a challenge to get this right.

Let’s ask the question differently – what are we trying to convey? 12.04 is an LTS. So we want it to be tough and long-lasting, reliable, solid as a rock and well defended. It’s also going to be the face of Ubuntu for large deployments for a long time, so we want it to have no loose ends, we want it to be coherent, neat.

We’ve told the story of the cloud in previous releases, and that comes to fruition in 12.04 with the first LTS that supports both the cloud guest, and cloud infrastructure, across ARM and x86 architectures. We’ve also told the story of Unity in previous releases, and that comes to fruition in a fast, lean interface that works well across clients both thick and thin. 12.04 is going to be a lot more than all that, but for the full reveal, you’ll need to wait till UDS! Nevertheless, we can take reliability, precision, and polish as a given.

Balancing all of those options, I think we have just the right mix in our designated mascot for 12.04 LTS. Ladies and gentlemen, I give you the Precise Pangolin.

Now, I’ve recently spent a few hours tracking a pangolin through the Kalahari. I can vouch for their precision – there wasn’t an ant hill in the valley that he missed. Their scales are a wonder of detail and quite the fashion statement. I can also vouch for their toughness; pangolin’s regularly survive encounters with lions. All in all, a perfect fit. There’s no sassier character, and no more cheerful digger, anywhere in those desert plains. If you want a plucky partner, the pangolin’s your match. Let’s pack light for a wonderful adventure together. See you in Orlando!

Technical Board 2011

Wednesday, October 5th, 2011

After the recent poll of Ubuntu developers I’m delighted to introduce the Technical Board 2011-2013. I think it’s worth noting that three of the members of this generation of technical leaders are not Canonical employees, though admittedly they are all former members of that team. I think there’s cause for celebration on both fronts: broader institutional and independent representation in the senior governance structures of Ubuntu is valuable, and the fact that personal interest persists regardless of company affiliation is also indicative of the character of the whole community, both full-time and volunteer. We’re in this together, for mutual interests.

Without further ado, here they are, in an order you are welcome to guess ;-)

  • St├ęphane Graber
  • Kees Cook
  • Martin Pitt
  • Matt Zimmerman
  • Colin Watson
  • Soren Hansen
Please join me in congratulating each of them, and thanking those who were willing to stand, who were nominated, and those who participated in the poll.
From my perspective, it was a very rich field of nominations. We had several candidates with no historic link to Canonical, which was very encouraging in terms of the diversity of engagement in the project. For the first time, I felt we had too many candidates and so I whittled down the final list of nominations – as it happens, all of the non-Canonical nominees made the shortlist, though that was not a criteria for my support.
Welcome aboard, all!

Building clouds for fun and profit

Monday, September 19th, 2011

So you’d like to spin up an internal cloud for hadoop or general development, shifting workloads from AWS to your own infrastructure or prototyping some new cloud services?

Call Canonical’s cloud infrastructure design and consulting team.

There are a couple of scenarios that we’re focused on at the moment, where we can offer standardised engagements:

  • Telco’s building out cloud infrastructures for public cloud services. These are aiming for specific markets based on geography or network topology – they have existing customers and existing networks and a competitive advantage in handling outsourced infrastructure for companies that are well connected to them, as well as a jurisdictional advantage over the global public cloud providers.
  • Cloud infrastructure prototypes at a division or department level. These are mostly folk who want the elasticity and dynamic provisioning of AWS in a private environment, often to work on products that will go public on Rackspace or AWS in due course, or to demonstrate and evaluate the benefits of this sort of architecture internally.
  • Cloud-style legacy deployments. These are folk building out HPC-type clusters running dedicated workloads that are horizontally scaled but not elastic. Big Hadoop deployments, or Condor deployments, fall into this category.

Cloud has become something of a unifying theme in many of our enterprise and server-oriented conversations in the past six months. While not everyone is necessarily ready to shift their workloads to a dynamic substrate like Ubuntu Cloud Infrastructure (powered by OpenStack) it seems that most large-scale IT deployments are embracing cloud-style design and service architectures, even when they are deploying on the metal. So we’ve put some work into tools which can be used in both cloud and large-scale-metal environments, for provisioning and coordination.

With 12.04 LTS on the horizon, OpenStack exploding into the wider consciousness of cloud-savvy admins, and projects like Ceph and CloudFoundry growing in stature and capability, it’s proving to be a very dynamic time for IT managers and architects. Much as the early days of the web presented a great deal of hype and complexity and options, only to settle down into a few key standard practices and platforms, cloud infrastructure today presents a wealth of options and a paucity of clarity; from NoSQL choices, through IAAS choices, through PAAS choices. Over the next couple of months I’ll outline how we think the cloud stack will shape up. Our goal is to make that “clean, crisp, obvious” deployment Just Work, bringing simplicity to the cloud much as we strive to bring it on the desktop.

For the moment, though, it’s necessary to roll up sleeves and get hands a little dirty, so the team I mentioned previously has been busy bringing some distilled wisdom to customers embarking on their cloud adventures in a hurry. Most of these engagements started out as custom consulting and contract efforts, but there are now sufficient patterns that the team has identified a set of common practices and templates that help to accelerate the build-out for those typical scenarios, and packaged those up as a range of standard cloud building offerings.

 

Surveying participation

Friday, September 9th, 2011

Just a brief note to celebrate Jono and team’s recent work on gathering insight into our membership and developer participation processes. Thanks also to those who took time to comment for the surveys. The results are worth a read if you care about the vibrancy and dynamism of our community. Kudos Jono, and thanks!

Dash takes shape for 11.10 Unity

Tuesday, August 16th, 2011

Our goal with Unity is unprecedented ease of use, visual style and performance on the Linux desktop. With feature freeze behind us, we have a refined target render of the Dash for Oneiric, and here it is:

click for the full size render.

Scopes and Lenses

We’ve moved from the idea of “Places” to a richer set of “Scopes and Lenses”. Scopes are data sources, and can tap into any online or offline data set as long as they can generate categorised results for a search, describe a set of filters and support some standard interfaces. Lenses are various ways to present the data that come from Scopes.

The Scopes have a range of filtering options they can use, such as ratings (“show me all the 5 star apps in the Software Center please”) and categories (“… that are games or media related”). Over time, the sophistication of this search system will grow but the goal is to keep it visual and immediate – something anyone can drive at first attempt.

This delivers on the original goal of creating a device-like experience that was search driven. Collaboration with the always-excellent Zeitgeist crew (quite a few of whom are now full time on the Unity team!) has improved the search experience substantially, kudos to them for the awesome work they’ve put in over the past six months. Since we introduced the Dash as a full screen device-like search experience, the same idea has made its way into several other shells, most notably Mac OS X Lion. While we’re definitely the outsider in this contest, I think we can stay one step ahead in the game given the support of our community.

The existing Places are all in the process of being updated to the Scopes and Lenses model, it’s a bit of a construction site at the moment so hard-hats are advised but dive in if you have good ideas for some more interesting scopes. I’ve heard all sorts of rumours about cool scopes in the pipeline ;-) and I bet this will be fertile ground for innovation. It’s pretty straightforward to make a scope, I’m sure others will blog and document the precise mechanisms but for those who want a head start, just use the source, Luke.

Panel evolution

In the panel, you’ll see that the top left corner is now consistently used to close whatever has the focus. Maximising a window keeps the window controls in the same position relative to the window – the top left corner. We have time to refine the behaviour of this based on user testing of the betas; for example, in one view, one should be able to close successive windows from that top left corner even if they are not maximised.

It’s taken several releases of careful iteration to get to this point. Even though we had a good idea where we were headed, each step needed to be taken one release at a time. Perhaps this might make a little clearer the reasons for the move of window controls to the left – it was the only place where we could ultimately keep them consistent all the way up to a maximised window with the title bar integrated into the panel. I’m confident this part will all be settled by 12.04.

As part of this two-step shuffle, the Dash invocation is now integrated in the Launcher. While this is slightly less of a Fitts-fantastic location, we consider it appropriate for a number of reasons. First, it preserves the top left corner for closing windows. Second, the Dash is best invoked with the Super key (sometimes erroneously and anachronistically referred to as the “Windows” key, for some reason ;-)). And finally, observations during user testing showed people as more inclined to try clicking on items in the Launcher than on the top left icon in the panel, unless that icon was something explicit like a close button for the window. Evidence based design rules.

Visual refinements

Rather than a flat darkening, we’re introducing a wash based on the desktop colour. The dash thus adjusts to your preferred palette based on your wallpaper. The same principle will drive some of the login experience – choosing a user will shift the login screen towards that users wallpaper and palette.

We’ve also integrated the panel and the dash, so indicators are rendered in a more holographic fashion inside the dash. Together with efforts to mute the contrast of Launcher icons the result is a more striking dash altogether: content is presented more dramatically.

Since we have raw access to the GL pipeline, we’re taking advantage of that with some real-time blur effects to help the readability and presentation of overlay content in the Dash, too. Both Nux in the case of Unity-3D and Qt in the case of Unity-2D have rich GL capabilities, and we’d like to make the most of whatever graphics stack you have on your hardware, while still running smoothly on the low end.

Growing community and ecosystem

A project like this needs diverse perspectives, talents and interests to make it feel rounded and complete. While Canonical is carrying the core load, and we’re happy to do so in order to bring this level of quality to the Ubuntu desktop user experience, what makes me particularly optimistic is the energy of the contributors both to Unity directly and to the integration of many other components and applications with the platform.

On the contribution front, a key goal for the Unity community is to maintain velocity in contributor patch flows. You should expect a rapid review and, all being well, landing, for contributions to Unity that are in line with the design goals. In a few cases we’ve also accepted patches that make it possible to use Unity in ways that are different to the design goals, especially where the evidence doesn’t lean very heavily one way or the other. Such contributions add some complexity but also give us the opportunity to test alternatives in a very rich way; the winning alternative would certainly survive, the other might not.

Contrary to common prognostication, this community is shaping up to be happy and productive. For those who do so for love and personal interest, participating in such a community should be fun and stimulating, an opportunity to exercise skills or pursue interests, give something back that will be appreciated and enjoyed by many, and help raise the bar for Linux experiences. I’d credit Jorge and others for their stewardship of this so far, and my heartfelt thanks to all of those who have helped make Unity better just for the fun of it.

Outside of the core, the growing number of apps that integrate sweetly with the launcher (quicklists), dash (scopes), indicators (both app-specific and category indicators) is helping to ensure that API’s are useful, refined and well implemented, as well as improving the experience of Ubuntu users everywhere. Now that we’re moving to Unity by default for both 2D and 3D, that’s even more valuable.

Under the hood

In this round, Unity-3D and Unity-2D have grown together and become twin faces on the same underlying model. They now share a good deal of common code and common services and – sigh – common bugs :-). But we’re now at the point where we can be confident that the Unity experience is available on the full range of hardware, from lightweight thin client systems made of ARM or Atom CPU’s to CADstations with oodles of GPU horsepower.

There’s something of a competition under way between proponents of the QML based Unity-2D, who believe that the GL support here is good enough to compete both at the high end and on the low end, and the GL-heads in Unity-3D, who think that the enhanced experiences possible with raw GL access justify the additional complexity of working in C++ and GL on the metal. Time will tell! Since a lot of the design inspiration for Unity came from game interfaces, I lean to the “let’s harness all the GL we can for the full 3D experience” side of the spectrum, but I’m intrigued with what the QML team are doing.

Corporate desktops and Ubuntu

Monday, August 15th, 2011

Good news for people with skills deploying and managing Ubuntu: the corporate desktop is being reinvented, and Ubuntu is a popular option for those leading the change.

In the past year there’s been a notable shift in the way IT shops think about their corporate desktops. Suddenly, Windows is optional, or at least it can be managed and delivered as a service to any other platform, so it no longer has to BE the platform on the client. In part, that’s because so much has moved to the web, and in part it’s because virtualisation has become so good at letting people deliver desktop apps (and whole desktops) over the network. It’s also a function of the success of other non-Windows platforms, like iOS, which make IT think in terms of standards for interoperability rather than standard applications.

All of this is drumming up interest in alternative ways to design large scale desktop infrastructure, from Linux-based thin clients (Ubuntu is at the heart of some recent products from Wyse) on alternative architectures like ARM to straightforward Ubuntu desktops with thin client software giving access to legacy Windows applications. In all these cases, Windows and proprietary software continue to play an important role, but the stranglehold of Windows on the platform itself seems to be coming unstuck. That makes for a much enhanced competitive landscape.

A migration from Windows to Ubuntu is still a project that requires a lot of planning, analysis and hard work. But for most institutions, it’s realistic to be confident that 10-25% of the desktops can migrate smoothly if a professional team has that as their mission over a year or two. For large organisations, that might be 5,000-50,000 seats, and the resulting savings are tremendous given the increase in Windows licensing costs driven by Win 7.

I joined a call recently with the team at Canonical that works with customers to plan and deliver desktop migrations to Ubuntu. They have a standard engagement process that charts a course for the organisation and maps out typical risks and low-hanging fruit. They were talking to a bank, traditionally a very conservative audience, about the stages and milestones in a typical migration of 20,000 seats to Ubuntu. I was struck by the tone of the conversation on both sides – it wasn’t a question of whether to do it, it was a question of how to do so most efficiently. And that’s a huge leap forward from the days when we used to speculate if it was sane to even think about Linux on the desktop for anybody other than a developer.

It’s clear that Windows is no longer the target – personal computing and productivity computing are in the process of being reinvented, and being an effective replacement for Windows is no guarantee of relevance in the future. But for many IT departments, the desktop represents an enormous cost base which will not disappear overnight, and Ubuntu is creating options for them to control that cost.

We often celebrate the way free software transforms the lives of those most in need, but it’s equally energising to see it making a difference to IT teams that in turn help inject resources into the acceleration of the free software platform. Winning 20,000 desktops to Ubuntu helps improve the platform for every school or university deployment, just as much as it helps improve the platform for developers and home users too.

11.04, a leap forward

Friday, April 29th, 2011

Users first, on free software. That has always been our mission: we set out to bring the joys and freedoms and innovation and performance and security that have always been part of the Linux platform, to a consumer audience. And yesterday marked the biggest leap forward in that mission that Ubuntu has ever taken, because in addition to the work we always do to make sure that the world’s best free software is polished and integrated, we brought something new to the very core of the user experience of the free platform: Unity.

We put user’s first because we committed to test and iterate Unity’s design with real users, and evolve it based on those findings. We’ve documented the process we’re following in that regard, so that other free software projects can decide for themselves if they also want to bring professional design into their process. I very much hope that this will become standard practice across all of free software, because in my view the future of free software is no longer just about inner beauty (architecture, performance, efficiency) it’s also about usability and style.

In the design of Unity we chose to be both humble and bold. Humble, because we have borrowed consciously from the work of other successful platforms, like Windows and MacOS. We borrowed what worked best, but then we took advantage of the fact that we are unconstrained by legacy and can innovate faster than they can, and took some bold leaps forward. In category indicators, the dash, overlay scrollbars and other innovations we are pioneering desktop experiences that I am sure will be emulated elsewhere, in both the free and proprietary platforms. This is the public “1.0″, there are rough points which will affect some users more than others, but we will iterate and polish them up one by one. Our goal should be to continue to set the pace and push free software to the forefront of usability and experience, growing the awesome Ubuntu and Unity community that shares those values and is excited by those ideas.

Ubuntu’s killer feature remains that community. The spirit of Ubuntu is about understanding that the measure of our own lives is in the way we improve the lives of others. Ubuntu has both economic and human dimensions: it is unique in bringing those together in a way which enables them to support one another. The fact that so many people recognise that their time, energy and expertise can have the biggest possible impact when expressed through Ubuntu is what makes their individual contributions so much more valuable. By recognising that it’s not just about bits, or licenses, or artwork, or documentation, or advocacy, or support, or assurance, or services, but that it’s about the whole of those in synthesis, we make something different to what the world has ever seen before. So to everyone who has helped bring Ubuntu 11.04 to fruition: thank you, and well done.

Of course, Ubuntu is far bigger than Unity. And the needs of the Ubuntu community, and users of Ubuntu, are far more diverse than simply Unity could address. So I’m proud of the fact that the Ubuntu community publishes the whole expression of software freedom across its archives. Kubuntu continues to improve and set a very high standard for the KDE experience. Lubuntu, the LXDE based expression of Ubuntu, is moving towards being 100% integrated. There is unique work being done in Ubuntu for users of the cloud and other server-oriented configurations. While we can be proud of what’s been achieved in Unity, we are equally proud of the efforts that go into ensuring that the full range of experiences is accommodated, to the extent possible with the effort put in by our huge community, under the Ubuntu umbrella.

We’re committed to keeping that the case. By welcoming all participants, and finding ways to accommodate and celebrate their differences rather than using them as grounds for divisiveness, we make something that is bigger than all our individual dreams.

Next after Natty?

The naming of cats is a difficult matter
It isn’t just one of your holiday games.
- T S Eliot, The Naming of Cats

For the next cycle, I think we’ll leave the oceanic theme behind. The “oddball octopus”, for example, is a great name but not one we’ll adopt this time around. Perhaps in 13 years time, though!

The objective is to capture the essence of our next six months work in a simple name. Inevitably there’s an obliquity, or offbeat opportunism in the result. And perhaps this next release more than most requires something other than orthodoxy – the skunkworks are in high gear right now. Fortunately I’m assured that if one of Natty’s successors is a skunk, it would at least be a sassy skunk!

So we’re looking for a name that conveys mysterious possibility, with perhaps an ounce of overt oracular content too. Nothing too opaque, ornate, odious or orotund. Something with an orderly ring to it, in celebration of the crisp clean cadence by which we the community bring Ubuntu forth.

There’s something neat in the idea that 11.10 will mark eight years since Ubuntu was conceived (it took a little longer to be born). So “octennial” might suit… but that would be looking backwards, and we should have an eye on the future, not the past. Hmm… an eye on the future, perhaps ocular? Or oculate? We’re certainly making our way up the S-curve of adoption, so perhaps ogee would do the trick?

Alternatively, we could celebrate the visual language of Ubuntu with the “orange okapi”, or the welcoming nature of our community with the “osculant orangutan”. Nothing hugs quite like dholbach, though, and he’s no hairy ape.

What we want is something imaginative, something dreamy. Something sleek and neat, too. Something that has all the precision of T S Eliot’s poetry, matched with the “effable ineffability” of our shared values, friendship and expertise. Something that captures both the competence of ubuntu-devel with the imagination of ayatana.

Which leads us neatly to the Oneiric Ocelot.

Oneiric means “dreamy”, and the combination with Ocelot reminds me of the way innovation happens: part daydream, part discipline.

We’ll need to keep up the pace of innovation on all fronts post-Natty. Our desktop has come together beautifully, and in the next release we’ll complete the cycle of making it available to all users, with a 2D experience to complement the OpenGL based Unity for those with the hardware to handle it. The introduction of Qt means we’ll be giving developers even more options for how they can produce interfaces that are both functional and aesthetically delightful.

In the cloud, we’ll have to tighten up and make some firm decisions about the platforms we can support for 12.04 LTS. UDS in Budapest will be full of feisty debate on that front, I’m sure, but I’m equally sure we can reach a pragmatic consensus and start to focus our energies on delivering the platform for widespread cloud computing on free and flexible terms.

Ubuntu is now shipping on millions of systems from multiple providers every year. It makes a real difference in the lives of millions, perhaps tens of millions, of people. As MPT said, “what we do is not only art, it’s performance art”. Every six months the curtains part, and we have to be ready for the performance. I’d like to thank the thousands of people who are actively participating in the production of Natty: take the initiative, take responsibility, take action, and your work will make a difference to all of those users. There are very few places in the world where a personal intellectual contribution can have that kind of impact. And very few places where we have such a strong social fabric around those intellectual challenges, too. We each do what we do for our own reasons, but it’s the global impact of Ubuntu which gives meaning to that action.

Natty is a stretch release: we set out to redefine the look and feel of the free desktop. We’ll need all the feedback we can get, so please test today’s daily, or A3, and file bug reports! Keep up the discipline and focus on the Narwhal, and let’s direct our daydreaming to the Ocelot.

A wit said of Google Wave “if your project depends on reinventing scrollbars, you are doing something wrong.” But occasionally, just occasionally, one gets to do exactly that.

Under the Ayatana banner, we’ve been on a mission to make the desktop have less chrome and more content. The goal is to help people immerse themselves in their stuff, without being burdened with large amounts of widgetry which isn’t relevant to the thing they are trying to concentrate on. And when it comes to widgetry, there are few things left which take up more space than scrollbars.

For example, I spend plenty of time in a full screen terminal, and it’s lovely to see how clean that experience is on Natty today:

…but that scrollbar on the right seems heavy and outdated. We took inspiration from mobile devices, and started exploring the idea of making scrollbars be more symbolic, and less physical. Something like this:

Of course, since the desktop isn’t often a touch device, we need to think through pointer interactions. We wanted to preserve the idea of keeping content exposed as much as possible, while still providing for pointer interaction when needed. We also decided to drop the “one line scroll” capability, while preserving the ability to page up and down. Take a look at the result:

Overlay Scrollbars in Unity – implementation from Canonical Design on Vimeo.

The design work behind this has been done by Christian Giordano, who worked through the corner cases (literally) and provided a mockup for testing purposes. And the heavy lifting for Natty is being done by the indefatigable Andrea Cimitan, who is currently polishing up a gtk implementation of the concept for the release. Christian put together a blog post on the subject, and a great video which talks through the design process and a few of the challenges and solutions found:

Well done, guys.

Private cloud “in a box” from Dell

Friday, February 4th, 2011

It just got a lot easier, and faster, to get a cloud in the house. Simply buy a starting cloud from Dell, and add to it as you need it to grow. You’ll get a reference architecture of Ubuntu Enterprise Cloud on Dell’s cloud-focused, dense PowerEdge C servers, fully supported, with professional services if you need to stretch it in your own unique direction and want a little help.

It’s taken a hard year of what El Reg rather accurately and poignantly described as futzing around, to make all of the pieces fit together smoothly so it can Just Work, Ubuntu style. Think of that as a year of futzing you don’t have to do yourself :-)

Eucalyptus, which powers this EC2-compatible private cloud solution, is flexible in how its configured. We wanted to make sure that flexibility was expressed in the solution, and that there’s a clean path forward as the UEC platform evolves, or Eucalyptus adds new capabilities. We know this is an area of rapid change and wanted to make sure early adopters can keep up with that over time. We put a lot of work into making Ubuntu upgrades smooth, and aimed for the same simplicity here. As Marten Mickos of Eucalyptus blogged, “One of the main ideas behind private clouds is to make computing more agile, and these Dell-UEC boxes take this agility benefit to the next level.”

I’d like to thank the team at Dell, Eucalyptus and Canonical that did all the futzing on your behalf. It’s a job very well done. Enjoy!
