KDE Neon developer Harald Sitter was able to package up the KDE calculator, kcalc, in a snap that weighs in at a mere 320KB! How did he do it?

KCalc and KDE Frameworks snaps

Like most applications in KDE, kcalc depends on several KDE Frameworks (though not all), sets of libraries and services that provide the common functionality and shared UI/UX found in KDE and it’s suite of applications. This means that, while kcalc is itself a small application, it’s dependency chain is not. In the past, any KDE application snap had to include many megabytes of platforms dependencies, even for the smallest app.

Recently I introduced the new “content” interface that has been added to snapd. I used this interface to share plugin code with a text editor, but Harald has taken it even further and created a KDE Frameworks snap that can share the entire platform with applications that are built on it!

While still in the very early stages of development, this approach will allow the KDE project to deliver all of their applications as independent snaps, while still letting them all share the one common set of Frameworks that they depend on. The end result will be that you, the user, will get the very latest stable (or development!) version of the KDE platform and applications, direct from KDE themselves, even if you’re on a stable/LTS release of your distro.

If you are running a snap-capable distro, you can try these experimental packages yourself by downloading kde-frameworks-5_5.26_amd64.snap and kcalc_0_amd64.snap from Neon’s build servers, and installing them with “snap install –devmode –force-dangerous <snap_file>”. To learn more about how he did this, and to help him build more KDE application snaps, you can find Harald as <sitter> on #kde-neon on Freenode IRC.

Snaps are a great way to get the most up to date applications on your desktop without putting the security or stability or your system at risk. I’ve been snapping up a bunch of things lately and the potential this new paradigm offers is going to be revolutionary. Unfortunately nothing comes for free, and the security of snaps comes with some necessary tradeoffs like isolation and confinement, which reduces some of the power and flexibility we’ve become used to as Linux users.

But now the developers of the snappy system (snapd, snap-confine and snapcraft) are giving us back some of that missing flexibility in the form of a new “content” interface which allows you to share files (executables, libraries, or data) between the snap packages that you develop. I decided to take this new interface for a test drive using one of the applications I had recently snapped: Geany, my editor of choice. Geany has the ability to load plugins to extend it’s functionality, and infact has a set of plugins available in a separate Github repository from the application itself.

I already had a working snap for Geany, so the next thing I had to do was create a snap for the plugins. Like Geany itself, the plugins are hosted on GitHub and have a nice build configuration already, so turning it into a snap was pretty trivial. I used the autotools plugin in Snapcraft to pull the git source and build all of the available plugins. Because my Geany snap was built with Gtk+ 3, I had to build the plugins for the same toolkit, but other than that I didn’t have to do anything special.

parts:
 all-plugins:
 plugin: autotools
 source: git@github.com:geany/geany-plugins.git
 source-type: git
 configflags: [--enable-gtk3=yes --enable-all-plugins]

Now that I had a geany.snap and geany-plugins.snap, the next step was to get them working together. Specifically I wanted Geany to be able to see and load the plugin files from the plugins snap, so it was really just a one-way sharing. To do this I had to create both a slot and a plug using the content interface. Usually when you’re building snap you only use plugs, such as network or x11, because you are consuming services provided by the core OS. In those cases also you just have to provide the interface name in the list of plugs, because the interface and the plug have the same name.

But with the content interface you need to do more than that. Because different snaps will provide different content, and a single snap can provide multiple kinds of content, you have to define a new name that is specific to what content you are sharing. So in my geany-plugins snapcraft.yaml I defined a new kind of content that I called geany-plugins-all (because it contains all the geany plugins in the snap), and I put that into a slot called geany-plugins-slot which is how we will refer to it later. I told snapcraft that this new slot was using the content interface, and then finally told it what content to share across that interface, which for geany-plugins was the entire snap’s content.

slots:
 geany-plugins-slot:
 content: geany-plugins-all
 interface: content
 read:
 - /

With that I had one half of the content interface defined. I had a geany-plugins.snap that was able to share all of it’s content with another snap. The next step was to implement the plug half of the interface in my existing geany.snap. This time instead of using a slots: section I would define a plugs: section, with a new plug named geany-plugins-plug and again specifying the interface to be content just like in the slot. Here again I had to specify the content by name, which had to match the geany-plugins-all that was used in the slot. The names of the plug and slot are only relevant to the user who needs to connect them, it’s this content name that snapd uses to make sure they can be connected in the first place. Finally I had to give the plug a target directory for where the shared content will be put. I chose a directory called plugins, and when the snaps are connected the geany-plugins.snap content will be bind-mounted into this directory in the geany.snap

plugs:
 geany-plugins-plug:
 content: geany-plugins-all
 default-provider: geany-plugins
 interface: content
 target: plugins

Lastly I needed to tell snapcraft which app would use this interface. Since the Geany snap only has one, I added it there.

apps:
 geany:
 command: gtk-launch geany
 plugs: [x11, unity7, home, geany-plugins-plug]

Once the snaps were built, I could install them and the new plug and slot were automatically connected

$ snap interfaces
Slot                             Plug
geany-plugins:geany-plugins-slot geany:geany-plugins-plug

Now that put the plugins into the application’s snap space, but it wasn’t enough for Geany to actually find them. To do that I used Geany’s Extra plugin path preferences to point it to the location of the shared plugin files.

After doing that, I could open the Plugin manager and see all of the newly shared plugins. Not all of them work, and some assume specific install locations or access to other parts of the filesystem that they won’t have being in a snap. The Geany developers warned me about that, but the ones I really wanted appear to work.

I’ve had a Nexus 4 since 2013, and I’ve been using it to test out desktop convergence (where you run a desktop environment from the phone) ever since that feature landed just over a year ago. Usually that meant plugging it into my TV via HDMI to make sure it automatically switched to the larger screen, and playing a bit with the traditional windowed-mode of Unity 8, or checking on adaptive layouts in some of the apps. I’ve also run it for hours on end as a demo at conferences such as SCaLE, FOSSETCON, OSCON and SELF. But through all that, I’ve never used it as an actual replacement for my laptop. Until now.

Thanks Frontier

A bit of back-story first. I had been a Verizon FiOS customer for years, and recently they sold all of their FiOS business to Frontier. The transition has been…..less than ideal. A couple of weeks ago I lost all services (phone, TV and internet) and was eventually told that nobody would be out to fix it until the following day. I still had my laptop, but without internet access I couldn’t really do my job on it. And while Ubuntu on phones can offer up a Hotspot, that particular feature doesn’t work on the Nexus 4 (something something, driver, something). Which meant that the only device that I had which could get online was my phone.

No Minecraft for you

13528720_10154238389913419_2608531900571217522_nFortunately, the fact that I’ve been demoing convergence at conferences meant I had all of the equipment I needed to turn my phone into a desktop and keep right on working. I have a bluetooth mouse and keyboard, and a Slimport adapter that let’s me plug it into a bigger screen. But while a TV works for testing, it’s not really great for long-term work. Don’t get me wrong, working from the couch is nice, but the screen is just too far away for reading and writing. Fortunately for me, and unfortunately for my children, their computer is at a desk and is plugged into a monitor with HDMI ports. So I took it over for the day. They didn’t have internet either that day, so they didn’t miss out on much right?

A day of observations

Throughout the day I posted a series of comments on Google+ about my experience. You could go through my post history looking for them, but I’m not going to make you do that. So here’s a quick summary of what I learned:

  • 3G is not nearly fast enough for my daily work. It’s good when using my phone as a phone, doing one thing at a time. But it falls short of broadband when I’ve got a lot of things using it. Still, on that day it was better than my fiber optic service, so there’s that.
  • I had more apps installed on my phone than I thought I did. I was actually taken aback when I opened the Dash in desktop mode and I saw so many icons. It’s far more than I had on Android, though not quite as many as on my laptop.
  • Having a fully-functional Terminal is a lifesaver. I do a lot of my work from the terminal, including IRC, and having one with tabs and keyboard shortcuts for them is a must for me to work.
  • I missed having physical buttons on my keyboard for home/end and page up/down. Thankfully a couple of people came to my rescue in the comments and taught me other combinations to get those.
  • Unity 8 is Unity. Almost all of the keyboard shortcuts that have become second nature to me (an there are a lot of them) were there. There was no learning curve, I didn’t have to change how I did anything or teach myself something new.
  • The phone is still a phone. I got a call (from Frontier, reminding me about an appointment that never happened) while using the device as a desktop. It was a bit disorienting at first, I had forgotten that I was running the desktop the Nexus 4, so when a notification of an incoming call popped up on the screen I didn’t know what was happening. That only lasted a second though, and after clicking answer and picking up the device, I just used it as a phone. Pretty cool

Must go faster

While I was able to do pretty much all of my work that day thanks to my phone, it wasn’t always easy or fun, and I’m not ready to give up my laptop just yet. The Nexus 4 is simply not powerful enough for the kind of workload I was putting on it. But then again, it’s a nearly 4 year old phone, and wasn’t considered a powerhouse even when it was released. The newest Ubuntu phone on the market, the Meizu Pro 5, packs a whole lot more power, and I think it would be able to give a really nice desktop experience.

screenshot20160506_103257823During the Ubuntu Online Summit last week, my colleague Daniel Holbach came up with what he called a “10 day challenge” to some of the engineering manager directing the convergence work in Ubuntu. The idea is simple, try and use only the Unity 8 desktop for 10 working days (two weeks). I thought this was a great way to really identify how close it is to being usable by most Ubuntu users, as well as finding the bugs that cause the most pain in making the switch. So on Friday of last week, with UOS over, I took up the challenge.

Below I will discuss all of the steps that I went through to get it working to my needs. They are not the “official” way of doing it (there isn’t an official way to do all this yet) and they won’t cover every usage scenario, just the ones I faced. If you want to try this challenge yourself they will help you get started. If at any time you get stuck, you can find help in the #ubuntu-unity channel on Freenode, where the developers behind all of these components are very friendly and helpful.

Getting Unity 8

To get started you first need to be on the latest release of Ubuntu. I am using Ubuntu 16.04 (Xenial Xerus), which is the best release for testing Unity 8. You will also need the stable-phone-overlay PPA. Don’t let the name fool you, it’s not just for phones, but it is where you will find the very latest packages for Mir, Unity 8, Libertine and other components you will need. You can install is with this command:

sudo add-apt-repository ppa:ci-train-ppa-service/stable-phone-overlay

Then you will need to install the Unity 8 session package, so that you can select it from the login screen:

sudo apt install unity8-desktop-session

Note: The package above used to be unity8-desktop-session-mir but was renamed to just unity-desktop-session.

When I did this there was a bug in the libhybris package that was causing Mir to try and use some Android stuff, which clearly isn’t available on my laptop. The fix wasn’t yet in the PPA, so I had to take the additional step of installing a fix from our continuous integration system (Note: originally the command below used silo 53, but I’ve been told it is now in silo 31). If you get a black screen when trying to start your Unity 8 session, you probably need this too.

sudo apt-get install phablet-tools phablet-tools-citrain
citrain host-upgrade 031

Note: None of the above paragraph is necessary anymore.

This was enough to get Unity 8 to load for me, but all my apps would crash within a half second of being launched. It turned out to be a problem with the cgroups manager, specifically the cgmanager service was disabled for me (I suspect this was leftover configurations from previous attempts at using Unity 8). After re-enabling it, I was able to log back into Unity 8 and start using apps!

sudo systemctl enable cgmanager

Essential Core Apps

The first thing you’ll notice is that you don’t have many apps available in Unity 8. I had probably more than most, having installed some Ubuntu SDK apps natively on my laptop already. If you haven’t installed the webbrowser-app already, you should. It’s in the Xenial archive and the PPA you added above, so just

sudo apt install webbrowser-app

But that will only get you so far. What you really need are a terminal and file manager. Fortunately those have been created as part of the Core Apps project, you just need to install them. Because the Ubuntu Store wasn’t working for me (see bottom of this post) I had to manually download and install them:

sudo click install --user mhall com.ubuntu.filemanager_0.4.525_multi.click
sudo click install --user mhall com.ubuntu.terminal_0.7.170_multi.click

If you want to use these apps in Unity 7 as well, you have to modify their .desktop files located in ~/.local/share/applications/ and add the -x flag after aa-exec-click, this is because by default it prevents running these apps under X11 where they won’t have the safety of confinement that they get under Mir.

The file manager needed a bit of extra effort to get working. It contains many Samba libraries that allow it to access windows network shares, but for some reason the app was looking for them in the wrong place. As a quick and dirty hack, I ended up copying whatever libraries it needed from /opt/click.ubuntu.com/com.ubuntu.filemanager/current/lib/i386-linux-gnu/ to /usr/lib/i386-linux-gnu/samba/. It’s worth the effort, though, because you need the file manager if you want do things like upload files through the webbrowser.

Using SSH

IRC is a vital communication tool for my job, we all use it every day. In fact, I find it so important that I have a remote client that stays connected 24/7, which I connect to via ssh. Thanks to the Terminal core app, I have quick and easy access to that. But when I first tried to connect to my server, which uses public-key authentication (as they all should), my connection was refused. That is because the Unity 8 session doesn’t run the ssh-agent service on startup. You can start it manually from the terminal:

ssh-agent

This will output some shell commands to setup environment variables, copy those and paste them right back into your terminal to set them. Then you should be able to ssh like normal, and if your key needs a passphrase you will be prompted for it in the terminal rather than in a dialog like you get in Unity 7.

Getting traditional apps

Now that you’ve got some apps running natively on Mir, you probably want to try out support for all of your traditional desktop apps, as you’ve heard advertised. This is done by a project called Libertine, which creates an LXC container and XMir to keep those unconfined apps safely away from your new properly confined setup. The first thing you will need to do is install the libertine packages:

apt-get install libertine libertine-scope

screenshot20160506_105035760Once you have those, you will see a Libertine app in your Apps scope. This is the app that lets you manage your Libertine containers (yes, you can have more than one), and install apps into them. Creating a new container is simply a matter of pressing the “Install” button. You can give it a name of leave it blank to get the default “Xenial”.

screenshot20160506_105618896Once your container is setup, you can install as many apps into it as you want, again using the Libertine container manager. You can even use it to search the archives if you don’t know the exact package name. It will also install any dependencies that package needs into your Libertine container.

screenshot20160506_105942480Now that you have your container setup and apps installed into it, you are ready to start trying them out. For now you have to access them from a separate scope, since the default Apps scope doesn’t look into Libertine containers. That is why you had to install the libertine-scope package above. You can find this scope by clicking on the Dash’s bottom edge indicator to open the Scopes manger, and selecting the Legacy Applications Scope. There you will see launchers for the apps you have installed.

Libertine uses a special container manager to launch apps. If it isn’t running, as was the case for me, your legacy app windows will remain black. To fix that, open up the terminal and manually start the manager:

initctl --session start libertine-lxc-manager

Theming traditional apps

screenshot20160506_122713187By default the legacy apps don’t look very nice. They default to the most basic of themes that look like you’ve time-traveled back to the mid-1990s, and nobody wants to do that. The reason for this is because these apps (or rather, the toolkit they use) expect certain system settings to tell them what theme to use, but those settings aren’t actually a dependency of the application’s package. They are part of a default desktop install, but not part of the default Libertine image.

screenshot20160506_112259969I found a way to fix this, at least for some apps, by installing the light-themes and ubuntu-settings packages into the Libertine container. Specifically it should work for any Gtk3 based application, such as GEdit. It does not, however, work for apps that still use the Gtk2 toolkit, such as Geany. I have not dug deeper to try and figure out how to fix Gtk2 themes, if anybody has a suggestion please leave it in the comments.

What works

It has been a couple of months since I last tried the Unity 8 session, back before I upgraded to Xenial, and at that time there wasn’t much working. I went into this challenge expecting it to be better, but not by much. I honestly didn’t expect to spend even a full day using it. So I was really quite surprised to find that, once I found the workarounds above, I was not only able to spend the full day in it, but I was able to do so quite easily.

screenshot20160509_121832656Whenever you have a new DE (which Unity 8 effectively is) and the latest UI toolkit (Qt 5) you have to be concerned about performance and resource use, and given the bleeding-edge nature of Unity 8 on the desktop, I was expecting to sacrifice some CPU cycles, battery life and RAM. If anything, the opposite was the case. I get at least as many hours on my battery as I do with Unity 7, and I was using less than half the RAM I typically do.

screenshot20160509_103139434Moreover, things that I was expecting to cause me problems surprisingly didn’t. I was able to use Google Hangouts for my video conferences, which I knew had just been enabled in the browser. But I fully expected suspend/resume to have trouble with Mir, given the years I spent fighting it in X11 in the past, but it worked nearly flawlessly (see below). The network indicator had all of my VPN configurations waiting to be used, and they worked perfectly. Even pulse audio was working as well as it did in Unity 7, though this did introduce some problems (again, see below). It even has settings to adjust the mouse speed and disable the trackpad when I’m typing. Most imporantly, nearly all of the keyboard shortcuts that have become subconcious to me in Unity 7 are working in Unity 8.

Most importantly, I was able to write this blog post from Unity 8. That includes taking all of the screenshots and uploading them to WordPress. Switching back and forth between my browser and my notes document to see what I had done over the last few days, or going to the terminal to verify the commands I mentioned above.

What doesn’t

Of course, it wasn’t all unicorns and rainbows, Unity 8 is still very bleeding edge as a desktop shell, and if you want to use it you need to be prepared for some pain. None of it has so far been bad enough to stop me, but your mileage may vary.

One of the first minor pain-points is the fact that middle-click doesn’t paste the active text highlight. I hadn’t realized how much I have become dependent on that until I didn’t have it. You also can’t copy/paste between a Mir and an XMir window, which makes legacy apps somewhat less useful, but that’s on the roadmap to be fixed.

Speaking of windows, Unity 8 is still limited to one per app. This is going to change, but it is the current state of things. This doesn’t matter so much for native apps, which were build under this restriciton, and the terminal app having tabs was a saving grace here. But for legacy apps it presents a bigger issue, especially apps like GTG (Getting Things Gnome) where multi-window is a requirement.

Some power-management is missing too, such as dimming the screen after some amount of inactivity, or turning it off altogether. The session also will not lock when you suspend it, so don’t depend on this in a security-critical way (but really, if you’re running bleeding-edge desktops in security-critical environments, you have bigger problems).

I also had a minor problem with my USB headset. It’s actually a problem I have in Unity 7 too, since upgrading to Xenial the volume and mute controls don’t automatically switch to the headset, even though the audio output and input do. I had a workaround for that in Unity 7, I could open the sound settings and manually change it to the headset, at which point the controls work on it. But in Unity 8’s sound settings there is no such option, so my workaround isn’t available.

The biggest hurdle, from my perspective, was not being able to install apps from the store. This is due to something in the store scope, online accounts, or Ubuntu One, I haven’t figured out which yet. So to install anything, I had to get the .click package and do it manually. But asking around I seem to be the only one having this problem, so those of you who want to try this yourself may not have to worry about that.

The end?

No, not for me. I’m on day 3 of this 10 day challenge, and so far things are going well enough for me to continue. I have been posting regular small updates on Google+, and will keep doing so. If I have enough for a new blog post, I may write another one here, but for the most part keep an eye on my G+ feed. Add your own experiences there, and again join #ubuntu-unity if you get stuck or need help.

As most you you know by now, Ubuntu 16.04 will be dropping the old Ubuntu Software Center in favor of the newer Gnome Software as the graphical front-end to both the Ubuntu archives and 3rd party application store.

Gnome Software

Gnome Software provides a lot of the same enhancements over simple package managers that USC did, and it does this using a new metadata format standard called AppStream. While much of the needed AppStream data can be extracted from the existing packages in the archives, sometimes that’s not sufficient, and that’s when we need people to help fill the gaps.

It turns out that the bulk of the missing or incorrect data is caused by the application icons being used by app packages. While most apps already have an icon, it was never strictly enforced before, and the size and format allowed by the desktop specs was more lenient than what’s needed now.  These lower resolution icons might have been fine for a menu item, but they don’t work very well for a nice, beautiful App Store interface like Gnome Software. And that’s where you can help!

Don’t worry, contributing icons isn’t hard, and it doesn’t require any knowledge of programming or packing to do. Best of all, you’ll not only be helping Ubuntu, but you’ll also be contributing to any other distro that uses the AppStream standard too! In the steps below I will walk you through the process of finding an app in need, getting the correct icon for it, and contributing it to the upstream project and Ubuntu.

1) Pick an App

Because the AppStream data is being automatically extracted from the contents of existing packages, we are able to tell which apps are in need of new icons, and we’ve generated a list of them, sorted by popularity (based on PopCon stats) so you can prioritize your contributions to where they will help the most users. To start working on one, first click the “Create” link to file a new bug report against the package in Ubuntu. Then replace that link in the wiki with a link to your new bug, and put your name in the “Claimed” column so that others know you’ve already started work on it.

Apps with Icon ErrorsNote that a package can contain multiple .desktop files, each of which has it’s own icon, and your bug report will be specific to just that one metadata file. You will also need to be a member of the ~ubuntu-etherpad team (or sub-team like ~ubuntumembers) in order to edit the wiki, you will be asked to verify that membership as part of the login process with Ubuntu SSO.

2) Verify that an AppStream icon is needed

While the extraction process is capable of identifying what packages have a missing or unsupported image in them, it’s not always smart enough to know which packages should have this AppStream data in the first place. So before you get started working on icons, it’s best to first make sure that the metadata file you picked should be part of the AppStream index in the first place.

Because AppStream was designed to be application-centric, the metadata extraction process only looks at those with Type=Application in their .desktop file. It will also ignore any .desktop files with NoDisplay=True in them. If you find a file in the list that shouldn’t be indexed by AppStream, chances are one or both of these values are set incorrectly. In that case you should change your bug description to state that, rather than attaching an icon to it.

3) Contact Upstream

Since there is nothing Ubuntu-specific about AppStream data or icons, you really should be sending your contribution upstream to the originating project. Not only is this best for Ubuntu (carrying patches wastes resources), but it’s just the right thing to do in the open source community. So the after you’ve chosen an app to work on and verfied that it does in fact need a new icon for AppStream, the very next thing you should do is start talking to the upstream project developers.

Start by letting them know that you want to contribute to their project so that it integrates better with AppStream enabled stores (you can reference these Guidelines if they’re not familiar with it), and opening a similar bug report in their bug tracker if they don’t have one already. Finally, be sure to include a link to that upstream bug report in the Ubuntu bug you opened previously so that the Ubuntu developers know the work is also going into upstream to (your contribute might be rejected otherwise).

4) Find or Create an Icon

Chances are the upstream developers already have an icon that meets the AppStream requirements, so ask them about it before trying to find one on your own. If not, look for existing artwork assets that can be used as a logo, and remember that it needs to be at least 64×64 pixels (this is where SVGs are ideal, as they can be exported to any size). Whatever you use, make sure that it matches the application’s current branding, we’re not out to create a new logo for them after all. If you do create a new image file, you will need to make it available under the CC-BY-SA license.

While AppStream only requires a 64×64 pixel image, many desktops (including Unity) will benefit from having even higher resolution icons, and it’s always easier to scale them down than up. So if you have the option, try to provide a 256×256 icon image (or again, just an SVG).

5) Submit your icon

Now that you’ve found (or created) an appropriate icon, it’s time to get it into both the upstream project and Ubuntu. Because each upstream will be different in how they want you to do that, you will need to ask them for guidance (and possibly assistance) in order to do that. Just make sure that you update the upstream bug report with your work, so that the Ubuntu developers can see that it’s been done.

Ubuntu 16.04 has already synced with Debian, so it’s too late for these changes in the upstream project to make their way into this release. In order to get them into 16.04, the Ubuntu packages will have to carry a patch until the changes that land in upstream have the time to make their way into the Ubuntu archives. That’s why it’s so important to get your contribution accepted into the upstream project first, the Ubuntu developers want to know that the patches to their packages will eventually be replaced by the same change from upstream.

attach_file_to_bugTo submit your image to Ubuntu, all you need to do is attach the image file to the bug report you created way back in step #1.

launchpad-subscribeThen, subscribe the “ubuntu-sponsors” team to the bug, these are the Ubuntu developers who will review and apply your icon to the target package, and get it into the Ubuntu archives.

6) Talk about it!

Congratulations, you’ve just made a contribution that is likely to affect millions of people and benefit the entire open source community! That’s something to celebrate, so take to Twitter, Google+, Facebook or your own blog and talk about it. Not only is it good to see people doing these kinds of contributions, it’s also highly motivating to others who might not otherwise get involved. So share your experience, help others who want to do the same, and if you enjoyed it feel free to grab another app from the list and do it again.

With the release of the Wily Werewolf (Ubuntu 15.10) we have entered into the Xenial Xerus (to be Ubuntu 16.04) development cycle. This will be another big milestone for Ubuntu, not just because it will be another LTS, but it will be the last LTS before we acheive convergence. What we do here will not only be supported for the next 5 years, it will set the stage for everything to come over that time as we bring the desktop, phone and internet-of-things together into a single comprehensive, cohesive platform.

To help get us there, we have a track dedicated to Convergence at this week’s Ubuntu Online Summit where we will be discussing plans for desktops, phones, IoT and how they are going to come together.

We’ll start the the convergence track at 1600 with the Ubuntu Desktop team talking about the QA (Quality Assurance) plans for the next LTS desktop, which will provide another 5 years of support for Ubuntu users. We’ll end the day with the Kubuntu team who are planning for their 16.04 (Xenial Xerus) release at 1900 UTC.

Wednesday

The second day kicks off at 1400 UTC with plans for what version of the Qt toolkit will ship in 16.04, something that now affects both the KDE and Unity 8 flavors of Ubuntu. That will be followed by development planning for the next Unity 7 desktop version of Ubuntu at 1500, and a talk on how legacy apps (.deb and X11 based) might be supported in the new Snappy versions of Ubuntu. We will end the day with a presentation by the Unity 8 developers at 1800 about how you can get started working on and contributing to the next generation desktop interface for Ubuntu.

Thursday

The third and last day of the Online Summit will begin with a live Questions and Answers session at 1400 UTC about the Convergence plans in general with the project and engineering managers who are driving it forward. At 1500 we’ll take a look at how those plans are being realized in some of the apps already being developed for use on Ubuntu phones and desktop. Then at 1600 UTC members of the design team will be talking to independent app developers about how to design their app with convergence in mind. We will then end the convergence track with a summary from KDE developers on the state and direction of their converged UI, Plama Mobile.

Plenaries

Outside of the Convergence track, you’ll want to watch Mark Shuttleworth’s opening keynote at 1400 UTC on Tuesday, and Canonical CEO Jane Silber’s live Q&A session at 1700 UTC on Wednesday.

Nicholas Skaggs presenting at UbuCon@FOSSETCON 2014

Thanks to the generous organizers of FOSSETCON who have given us a room at their venue, we will be having another UbuCon in Orlando this fall!

FOSSETCON 2015 will be held at the Hilton Orlando Lake Buena Vista‎, from November 19th through the 21st. This year they’ve been able to get Richard Stallman to attend and give a keynote, so it’s certainly an event worth attending for anybody who’s interested in free and open source software.

UbuCon itself will be held all day on the 19th in it’s own dedicate room at the venue. We are currently recruiting presenters to talk to attendees about some aspect of Ubuntu, from the cloud to mobile, community involved and of course the desktop. If you have a fun or interesting topic that you want to share with, please send your proposal to me at mhall119@ubuntu.com

Ubuntu is sponsoring the South East Linux Fest this year in Charlotte North Carolina, and as part of that event we will have a room to use all day Friday, June 12, for an UbuCon. UbuCon is a mini-conference with presentations centered around Ubuntu the project and it’s community.

I’m recruiting speakers to fill the last three hour-long slots, if anybody is willing and able to attend the conference and wants to give a presentation to a room full of enthusiastic Ubuntu users, please email me at mhall119@ubuntu.com. Topic can be anything Ubuntu related, design, development, client, cloud, using it, community, etc.

Ubuntu has been talking a lot about convergence lately, it’s something that we believe is going to be revolutionary and we want to be at the forefront of it. We love the idea of it, but so far we haven’t really had much experience with the reality of it.

image20150423_164034801I got my first taste of that reality two weeks ago, while at a work sprint in London. While Canonical has an office in London, it had other teams sprinting there, so the Desktop sprint I was at was instead held at a hotel. We planned to visit the office one day that week, it would be my first visit to any Canonical office, as well as my first time working at an actual office in several years. However, we also planned to meet up with the UK loco for release drinks that evening. This meant that we had to decide between leaving our laptops at the hotel, thus not having them to work on at the office, or taking them with us, but having to carry them around the pub all evening.

I chose to leave my laptop behind, but I did take my phone (Nexus 4 running Ubuntu) with me. After getting a quick tour of the office, I found a vacant seat at a desk, and pulled out my phone. Most of my day job can be done with the apps on my phone: I have email, I have a browser, I have a terminal with ssh, I can respond to our community everywhere they are active.

I spent the next couple of hours doing work, actual work, on my phone. The only problem I had was that I was doing it on a small screen, and I was burning through my battery. At one point I looked up and realized that the vacant desk I was sitting at was equipped with a laptop docking station. It had also a USB hub and an HDMI monitor cable available. If I had a slimport cable for my phone, I might have been able to plug it into this docking station and both power my phone and get a bigger screen to work with.

If I could have done that, I would have achieved the full reality of convergence, and it would have been just like if I had brought my laptop with me. Only with this I was able to simply slide it into my pocket when it was time to leave for drinks. It was tantalizingly close, I got a little taste of what it’s going to be like, and now I’m craving more of it.

A couple of weeks ago I had the opportunity to attend the thirteenth Southern California Linux Expo, more commonly known at SCaLE 13x. It was my first time back in five years, since I attended 9x, and my first time as a speaker. I had a blast at SCaLE, and a wonderful time with UbuCon. If you couldn’t make it this year, it should definitely be on your list of shows to attend in 2016.

UbuCon

Thanks to the efforts of Richard Gaskin, we had a room all day Friday to hold an UbuCon. For those of you who haven’t attended an UbuCon before, it’s basically a series of presentations by members of the Ubuntu community on how to use it, contribute to it, or become involved in the community around it. SCaLE was one of the pioneering host conferences for these, and this year they provided a double-sized room for us to use, which we still filled to capacity.

image20150220_100226891I was given the chance to give not one but two talks during UbuCon, one on community and one on the Ubuntu phone. We also had presentations from my former manager and good friend Jono Bacon, current coworkers Jorge Castro and Marco Ceppi, and inspirational community members Philip Ballew and Richard Gaskin.

I’d like thank Richard for putting this all together, and for taking such good care of those of us speaking (he made sure we always had mints and water). UbuCon was a huge success because of the amount of time and work he put into it. Thanks also to Canonical for providing us, on rather short notice, a box full of Ubuntu t-shirts to give away. And of course thanks to the SCaLE staff and organizers for providing us the room and all of the A/V equipment in it to use.

The room was recorded all day, so each of these sessions can be watched now on youtube. My own talks are at 4:00:00 and 5:00:00.

Ubuntu Booth

In addition to UbuCon, we also had an Ubuntu booth in the SCaLE expo hall, which was registered and operated by members of the Ubuntu California LoCo team. These guys were amazing, they ran the booth all day over all three days, managed the whole setup and tear down, and did an excellent job talking to everybody who came by and explaining everything from Ubuntu’s cloud offerings, to desktops and even showing off Ubuntu phones.

image20150221_162940413Our booth wouldn’t have happened without the efforts of Luis Caballero, Matt Mootz, Jose Antonio Rey, Nathan Haines, Ian Santopietro, George Mulak, and Daniel Gimpelevich, so thank you all so much! We also had great support from Carl Richell at System76 who let us borrow 3 of their incredible laptops running Ubuntu to show off our desktop, Canonical who loaned us 2 Nexus 4 phones running Ubuntu as well as one of the Orange Box cloud demonstration boxes, Michael Newsham from TierraTek who sent us a fanless PC and NAS, which we used to display a constantly-repeating video (from Canonical’s marketing team) showing the Ubuntu phone’s Scopes on a television monitor provided to us by Eäär Oden at Video Resources. Oh, and of course Stuart Langridge, who gave up his personal, first-edition Bq Ubuntu phone for the entire weekend so we could show it off at the booth.

image20150222_132142752Like Ubuntu itself, this booth was not the product of just one organization’s work, but the combination of efforts and resources from many different, but connected, individuals and groups. We are what we are, because of who we all are. So thank you all for being a part of making this booth amazing.

Last week was our second ever Ubuntu Online Summit, and it couldn’t have gone better. Not only was it a great chance for us in Canonical to talk about what we’re working on and get community members involved in the ongoing work, it was also an opportunity for the community to show us what they have been working on and give us an opportunity to get involved with them.

Community Track leads

This was also the second time we’ve recruited track leads from among the community. Traditionally leading a track was a responsibility given to one of the engineering managers within Canonical, and it was up to them to decide what sessions to put on the UDS schedule. We kept the same basic approach when we went to online vUDS. But starting with UOS 14.06, we asked leaders in the community to help us with that, and they’ve done a phenomenal job. This time we had Nekhelesh RamananthanJosé Antonio ReySvetlana BelkinRohan GargElfy, and Scarlett Clark take up that call, and they were instrumental in getting even more of the community involved

Community Session Hosts

uos_creatorsMore than a third of those who created sessions for this UOS were from the community, not Canonical. For comparison, in the last in-person UDS, less than a quarter of session creators were non-Canonical. The shift online has been disruptive, and we’ve tried many variations to try and find what works, but this metric shows that those efforts are starting to pay off. Community involvement, indeed community direction, is higher in these Online Summits than it was in UDS. This is becoming a true community event: community focused, community organized, and community run.

Community Initiatives

The Ubuntu Online Summit wasn’t just about the projects driven by Canonical, such as the Ubuntu desktop and phone, there were many sessions about projects started and driven by members of the community. Last week we were shown the latest development on Ubuntu MATE and KDE Plasma 5 from non-Canonical lead flavors. We saw a whole set of planning sessions for community developed Core Apps and an exciting new Component Store for app developers to share bits of code with each other. For outreach there were sessions for providing localized ISOs for loco teams and expanding the scope of the community-lead Start Ubuntu project. Finally we had someone from the community kick off a serious discussion about getting Ubuntu running on cars. Cars! All of these exciting sessions were thought up by, proposed by, and run by members of the community.

Community Improvements

This was a great Ubuntu Online Summit, and I was certainly happy with the increased level of community involvement in it, but we still have room to make it better. And we are going to make it better with help from the community. We will be sending out a survey to everyone who registered as attending for this UOS to gather feedback and ideas, please take the time to fill it out when you get the link. If you attended but didn’t register there’s still time, go to the link above, log in and save your attendance record. Finally, it’s never too early to start thinking about the next UOS and what sessions you might want to lead for it, so that you’re prepared when those track leads come knocking at your door.

A couple of people have reached out to me via LinkedIn and reminded me that my three year work anniversary happened last Friday. Three years since I left my job at a local place to go work for the Canonical where I got the chance to be paid to work on open source software and better my Python skills with the team working on Launchpad. My wife wasn’t quite sure. “You’ve only been at your job a year and a half, and your last one was only two years. What makes this different?”

What’s amazing, looking back, is just how *right* the decision turned out to be. I was nervous at the time. I really wasn’t Launchpad’s biggest fan. However, the team I interviewed with held this promise of making me a better developer. They were doing code reviews of every branch that went up to land. They had automated testing, and they firmly believed in unit and functional tests of the code. It was a case of the product didn’t excite me, but the environment, working with smart developers from across the globe, was exactly what I felt like I needed to move forward with my career, my craft.

2013-09-02 18.17.47

I joined my team on Launchpad in a squad of four other developers. It was funny. When I joined I felt so lost. Launchpad is an amazing and huge bit of software, and I knew I was in over my head. I talked with my manager at the time, Deryck, and he told me “Don’t worry, it’ll take you about a year to get really productive working on Launchpad.” A year! Surely you jest, and if you’re not jesting…wtf did I just get myself into?

It was a long road and over time I learned how to take a code review (a really hard skill for many of us), how to do one, and how to talk with other smart and opinionated developers. I learned the value of the daily standup, how to manage work across a kanban board. I learned to really learn from others. Up until this point I’d always been the big fish in a small pond and suddenly I was the minnow hiding in the shallows. Forget books on how to code, just look at the diff in the code review you’re reading right now. Learn!

My boss was right, it was nearly ten months before I really felt like I could be asked to do most things in Launchpad and get them done in an efficient way. Soon our team was moved on from Launchpad to other projects. It was actually pretty great. On the one hand, “Hey! I just got the hang of this thing” but, on the other hand, we were moving on to new things. Development life here has never been one of sitting still. We sit down and work on the Ubuntu cycle of six month plans, and it’s funny because even that is such a long time. Do you really know what you’ll be doing six months from now?

P1100197.jpg

Since that time in Launchpad I’ve gotten work on several different projects and I ended up switching teams to work on the Juju Gui. I didn’t really know a lot about this Juju thing, but the Gui was a fascinating project. It’s a really large scale JavaScript application. This is no “toss some jQuery on a web page” thing here.

I also moved to work under a new manager Gary. As my second manager since starting at Canonical and I was amazed at my luck. Here I’ve had two great mentors that made huge strides in teaching me how to work with other developers, how to do the fun stuff, the mundane, and how to take pride in the accomplishments of the team. I sit down at my computer every day and I’ve got the brain power of amazing people at my disposal over irc, Google Hangouts, email, and more. It’s amazing to think that at these sprints we do, I’m pretty much never the smartest person in the room. However, that’s what’s so great. It’s never boring and when there’s a problem the key is that we put our joint brilliant minds to the problem. In every hard problem we’ve faced I’ve never found that a single person had the one true solution. What we come up with together is always better than what any of us had apart.

When Gary left and there was a void for team lead and it was something I was interested in. I really can’t say enough awesome things about the team of folks I work with. I wanted to keep us all together and I felt like it would be great for us to try to keep things going. It was kind of a “well I’ll just try not to $#@$@# it up” situation. That was more than nine months ago now. Gary and Deryck taught me so much, and I still have to bite my tongue and ask myself “What would Gary do” at times. I’ve kept some things the same, but I’ve also brought my own flavor into the team a bit, at least I like to think so. These days my Github profile doesn’t show me landing a branch a day, but I take great pride in the progress of the team as a whole each and every week.

The team I run now is as awesome a group of people, the best I could hope to work for. I do mean that, I work for my team. It’s never the other way around and that’s one lesson I definitely picked up from my previous leads. The projects we’re working on are exciting and new and are really important to Canonical. I get to sit in and have discussions and planning meetings with Canonical super genius veterans like Kapil, Gustavo, and occasionally Mark Shuttleworth himself.

Looking back I’ve spent the last three years becoming a better developer, getting an on the job training course on leading a team of brilliant people, and crash course on thinking about the project, not just as the bugs or features for the week, but for the project as it needs to exist in three to six months. I’ve spent three years bouncing between “what have I gotten myself into, this is beyond my abilities” to “I’ve got this. You can’t find someone else to do this better”. I always tell people that if you’re not swimming as hard as you can to keep up, find another job. I feel like three years ago I did that and I’ve been swimming ever since.

P1040511.jpg

Three years is a long time in a career these days. It’s been a wild ride and I can’t thank the folks that let me in the door, taught me, and have given me the power to do great things with my work enough. I’ve worked by butt off in Budapest, Copenhagen, Cape Town, Brussels, North Carolina, London, Vegas, and the bay area a few times. Will I be here three years from now? Who knows, but I know I’ve got an awesome team to work with on Monday and we’ll be building an awesome product to keep building. I’m going to really enjoy doing work that’s challenging and fulfilling every step of the way.

Next week we will be kicking off the November 2014 Ubuntu Online Summit where people from the Ubuntu community and Canonical will be hosting live video sessions talking about what is being worked on, what is currently available, and what the future holds across all of the Ubuntu ecosystem.

uos_scheduleWe are in the process of recruiting sessions and filling out the Summit Schedule for this event, which should be finalized at the start of next week. You can register that you are attending on the Summit website, where you can also mark specific sessions that you are interested in and get a personalized view of your schedule (and an available iCal feed too!) UOS is designed for participation, not just consumption. Every session will have active IRC channel that goes along with it where you can speak directly to the people on video. For discussion sessions, you’re encouraged to join the video yourself when you want to join the conversation.

Moreover, we want you to host sessions! Anybody who has an idea for a good topic for conversation, presentation, or planning and is willing to host the video (meaning you need to run a Google On-Air Hangout) can propose a session. You don’t need to be a Canonical employee, project leader, or even an Ubuntu member to run a session, all you need is a topic and a willingness to be the person to drive it. And don’t worry, we have track leads who have volunteered to help you get it setup.

These sessions will be split into tracks, so you can follow along with the topics that interest you. Or you can jump from track to track to see what everybody else in the community is doing. And if you want to host a session yourself, you can contact any one of the friendly Track Leads, who will help you get it registered and on the schedule.

Ubuntu Development

Those who have participated in the Ubuntu Developer Summit (UDS) in the past will find the same kind of platform-focused topics and discussions in the Ubuntu Development track. This track covers everything from the kernel to packaging, desktops and all of the Ubuntu flavors.

The track leads are: Will CookeŁukasz ZemczakSteve LangasekAntonio Rosales, and Rohan Garg

App & Scope Development

For developers who are targeting the Ubuntu platform, for both apps and Unity scopes, we will be featuring a number of presentations on the current state of the tools, APIs and documentation, as well as gathering feedback from those who have been using them to help us improve upon them in Ubuntu 15.04. You will also see a lot of planning for the Ubuntu Core Apps, and some showcases of other apps or technologies that developers are creating.

The track leads are: Tim PeetersMichael HallAlan Pope, and Nekhelesh Ramananthan

Cloud & DevOps

Going beyond the core and client side, Ubuntu is making a lot of waves in the cloud and server market these days, and there’s no better place to learn about what we’re building (and help us build it) that the Cloud & Devops track. Whether you want to roll out your own OpenStack cloud, or make your web service easy to deploy and scale out, you will find topics here that interest you.

The track leads are: Antonio RosalesMarco CeppiPatricia Gaughen, and José Antonio Rey

Community

The Ubuntu Online Summit is itself a community coordinated event, and we’ve got a track dedicated to helping us improve and grow the whole community. You can use this to showcase the amazing work that your team has been doing, or plan out new events and projects for the coming cycle. The Community Team from canonical will be there, as well as members of the various councils, flavors and boards that provide governance for the Ubuntu project.

The track leads are: David PlanellaDaniel HolbachSvetlana Belkin, and José Antonio Rey

Users

And of course we can’t forget about our millions or users, we have a whole track setup just to provide them with resources and presentations that will help them make the most out Ubuntu. If you have been working on a project for Ubuntu, you should think about hosting a session on this track to show it off. We’ll also be hosting several feedback session to hear directly from users about what works, what doesn’t, and how we can improve.

The track leads are: Nicholas SkaggsElfy, and Scarlett Clark

Will CookeThis is a guest post from Will Cooke, the new Desktop Team manager at Canonical. It’s being posted here while we work to get a blog setup on unity.ubuntu.com, which is where you can find out more about Unity 8 and how to get involved with it.

Intro

Understandably, most of the Ubuntu news recently has focused around phones. There is a lot of excitement and anticipation building around the imminent release of the first devices.  However, the Ubuntu Desktop has not been dormant during this time.  A lot of thought and planning has been given to what the desktop will become in the future; who will use it and what will they use it for.  All the work which is going in to the phone will be directly applicable to the desktop as well, since they will use the same code.  All the apps, the UI tweaks, everything which makes applications secure and stable will all directly apply to the desktop as well.  The plan is to have the single converged operating system ready for use on the desktop by 16.04.

The plan

We learned some lessons during the early development of Unity 7. Here’s what happened:

  • 11.04: New Unity as default
  • 11.10: New Unity version
  • 12.04: Unity in First LTS

What we’ve decided to do this time is to keep the same, stable Unity 7 desktop as the default while we offer users who want to opt-in to Unity8 an option to use that desktop. As development continues the Unity 8 desktop will get better and better.  It will benefit from a lot of the advances which have come about through the development of the phone OS and will benefit from continual improvements as the releases happen.

  • 14.04 LTS: Unity 7 default / Unity 8 option for the first time
  • 14.10: Unity 7 default / Unity 8 new rev as an option
  • 15.04: Unity 7 default / Unity 8 new rev as an option
  • 15.10: Potentially Unity 8 default / Unity 7 as an option
  • 16.04 LTS: Unity 8 default / Unity 7 as an option

As you can see, this gives us a full 2 cycles (in addition to the one we’ve already done) to really nail Unity 8 with the level of quality that people expect. So what do we have?

How will we deliver Unity 8 with better quality than 7?

Continuous Integration is the best way for us to achieve and maintain the highest quality possible.  We have put a lot of effort in to automating as much of the testing as we can, the best testing is that which is performed easily.  Before every commit the changes get reviewed and approved – this is the first line of defense against bugs.  Every merge request triggers a run of the tests, the second line of defense against bugs and regressions – if a change broke something we find out about it before it gets in to the build.

The CI process builds everything in a “silo”, a self contained & controlled environment where we find out if everything works together before finally landing in the image.

And finally, we have a large number of tests which run against those images. This really is a “belt and braces” approach to software quality and it all happens automatically.  You can see, we are taking the quality of our software very seriously.

What about Unity 7?

Unity 7 and Compiz have a team dedicated to maintenance and bug fixes and so the quality of it continues to improve with every release.  For example; windows switching workspaces when a monitor gets unplugged is fixed, if you have a mouse with 6 buttons it works, support for the new version of Metacity (incase you want to use the Gnome2 desktop) – added (and incidentally, a lot of that work was done by a community contributor – thanks Alberts!)

Unity 7 is the desktop environment for a lot of software developers, devops gurus, cloud platform managers and millions of users who rely on it to help them with their everyday computing.  We don’t want to stop you being able to get work done.  This is why we continue to maintain Unity 7 while we develop Unity 8.  If you want to take Unity 8 for a spin and see how its coming along then you can; if you want to get your work done, we’re making that experience better for you every day.  Best of all, both of these options are available to you with no detriment to the other.

Things that we’re getting in the new Ubuntu Desktop

  1. Applications decoupled from the OS updates.  Traditionally a given release of Ubuntu has shipped with the versions of the applications available at the time of release.  Important updates and security fixes are back-ported to older releases where required, but generally you had to wait for the next release to get the latest and greatest set of applications.  The new desktop packaging system means that application developers can push updates out when they are ready and the user can benefit right away.
  2. Application isolation.  Traditionally applications can access anything the user can access; photos, documents, hardware devices, etc.  On other platforms this has led to data being stolen or rendered otherwise unusable.  Isolation means that without explicit permission any Click packaged application is prevented from accessing data you don’t want it to access.
  3. A full SDK for writing Ubuntu apps.  The SDK which many people are already using to write apps for the phone will allow you to write apps for the desktop as well.  In fact, your apps will be write once run anywhere – you don’t need to write a “desktop” app or a “phone” app, just an Ubuntu app.

What we have now

The easiest way to try out the Unity 8 Desktop Preview is to use the daily Ubuntu Desktop Next live image:   http://cdimage.ubuntu.com/ubuntu-desktop-next/daily-live/current/   This will allow you to boot into a Unity 8 session without touching your current installation.  An easy 10 step way to write this image to a USB stick is:

  1. Download the ISO
  2. Insert your USB stick in the knowledge that it’s going to get wiped
  3. Open the “Disks” application
  4. Choose your USB stick and click on the cog icon on the righthand side
  5. Choose “Restore Disk Image”
  6. Browse to and select the ISO you downloaded in #1
  7. Click “Start restoring”
  8. Wait
  9. Boot and select “Try Ubuntu….”
  10. Done *

* Please note – there is currently a bug affecting the Unity 8 greeter which means you are not automatically logged in when you boot the live image.  To log in you need to:

  1. Switch to vt1 (ctrl-alt-f1)
  2. type “passwd” and press enter
  3. press enter again to set the current password to blank
  4. enter a new password twice
  5. Check that the password has been successfully changed
  6. Switch back to vt7 (ctrl-alt-f7)
  7. Enter the new password to login

 

Here are some screenshots showing what Unity 8 currently looks like on the desktop:

00000009000000190000003100000055000000690000011000000183000001950000020700000255000002630000032800000481

The team

The people working on the new desktop are made up of a few different disciplines.  We have a team dedicated to Unity 7 maintenance and bug fixes who are also responsible for Unity 8 on the desktop and feed in a lot of support to the main Unity 8 & Mir teams. We have the Ubuntu Desktop team who are responsible for many aspects of the underlying technologies used such as GNOME libraries, settings, printing etc as well as the key desktop applications such as Libreoffice and Chromium.  The Ubuntu desktop team has some of the longest serving members of the Ubuntu family, with some people having been here for the best part of ten years.

How you can help

We need to log all the bugs which need to be fixed in order to make Unity 8 the best desktop there is.  Firstly, we need people to test the images and log bugs.  If developers want to help fix those bugs, so much the better.  Right now we are focusing on identifying where the work done for the phone doesn’t work as expected on the desktop.  Once those bugs are logged and fixed we can rely on the CI system described above to make sure that they stay fixed.

Ars Technica has a great write up by Lee Hutchinson on our Orange Box demo and training unit.

You can't help but have your attention grabbed by it!

You can’t help but have your attention grabbed by it!

As the comments are quick to point out – at the expense of the rest of the piece – the hardware isn’t the compelling story here. While you can buy your own, you can almost certainly hand build an equivalent-or-better set up for less money1, but Ars recognises this:

Of course, that’s exactly the point: the Orange Box is that taste of heroin that the dealer gives away for free to get you on board. And man, is it attractive. However, as Canonical told me about a dozen times, the company is not making them to sell—it’s making them to use as revenue driving opportunities and to quickly and effectively demo Canonical’s vision of the cloud.

The Orange Box is about showing off MAAS & Juju, and – usually – OpenStack.

To see what Ars think of those, you should read the article.

I definitely echo Lee’s closing statement:

I wish my closet had an Orange Box in it. That thing is hella cool.


  1. Or make one out of wood like my colleague Gavin did!

This is really inspiring to me, on several levels: as an Ubuntu member, as a Canonical, and as a school governor.

Not only are they deploying Ubuntu and other open-source software to their students, they are encouraging those students to tinker with their laptops, and – better yet – some of those same students are directly involved in the development, distribution, and providing support for their peers. All of those students will take incredibly valuable experience with them into their future careers.

Well done.

A couple of months ago Jono announced the dates for the Ubuntu Online Summit, June 10th – 12th,  and those dates are almost upon us now.  The schedule is opened, the track leads are on board, all we need now are sessions.  And that’s where you come in.

Ubuntu Online Summit is a change for us, we’re trying to mix the previous online UDS events with our Open Week, Developer Week and User Days events, to try and bring people from every part of our community together to celebrate, educate, and improve Ubuntu. So in addition to the usual planning sessions we had at UDS, we’re also looking for presentations from our various community teams on the work they do, walk-throughs for new users learning how to use Ubuntu, as well as instructional sessions to help new distro developers, app developers, and cloud devops get the most out of it as a platform.

What we need from you are sessions.  It’s open to anybody, on any topic, anyway you want to do it.  The only requirement is that you can start and run a Google+ OnAir Hangout, since those are what provide the live video streaming and recording for the event.  There are two ways you can propose a session: the first is to register a Blueprint in Launchpad, this is good for planning session that will result in work items, the second is to propose a session directly in Summit, which is good for any kind of session.  Instructions for how to do both are available on the UDS Website.

There will be Track Leads available to help you get your session on the schedule, and provide some technical support if you have trouble getting your session’s hangout setup. When you propose your session (or create your Blueprint), try to pick the most appropriate track for it, that will help it get approved and scheduled faster.

Ubuntu Development

Many of the development-oriented tracks from UDS have been rolled into the Ubuntu Development track. So anything that would previously have been in Client, Core/Foundations or Cloud and Server will be in this one track now. The track leads come from all parts of Ubuntu development, so whatever you session’s topic there will be a lead there who will be familiar with it.

Track Leads:

  • Łukasz Zemczak
  • Steve Langasek
  • Leann Ogasawara
  • Antonio Rosales
  • Marc Deslaurs

Application Development

Introduced a few cycles back, the Application Development track will continue to have a focus on improving the Ubuntu SDK, tools and documentation we provide for app developers.  We also want to introduce sessions focused on teaching app development using the SDK, the various platform services available, as well as taking a deeper dive into specifics parts of the Ubuntu UI Toolkit.

Track Leads:

  • Michael Hall
  • David Planella
  • Alan Pope
  • Zsombor Egri
  • Nekhelesh Ramananthan

Cloud DevOps

This is the counterpart of the Application Development track for those with an interest in the cloud.  This track will have a dual focus on planning improvements to the DevOps tools like Juju, as well as bringing DevOps up to speed with how to use them in their own cloud deployments.  Learn how to write charms, create bundles, and manage everything in a variety of public and private clouds.

Track Leads:

  • Jorge Castro
  • Marco Ceppi
  • Patricia Gaughen
  • Jose Antonio Rey

Community

The community track has been a stable of UDS for as long as I can remember, and it’s still here in the Ubuntu Online Summit.  However, just like the other tracks, we’re looking beyond just planning ways to improve the community structure and processes.  This time we also want to have sessions showing users how they can get involved in the Ubuntu community, what teams are available, and what tools they can use in the process.

Track Leads:

  • Daniel Holbach
  • Jose Antonio Rey
  • Laura Czajkowski
  • Svetlana Belkin
  • Pablo Rubianes

Users

This is a new track and one I’m very excited about. We are all users of Ubuntu, and whether we’ve been using it for a month or a decade, there are still things we can all learn about it. The focus of the Users track is to highlight ways to get the most out of Ubuntu, on your laptop, your phone or your server.  From detailed how-to sessions, to tips and tricks, and more, this track can provide something for everybody, regardless of skill level.

Track Leads:

  • Elizabeth Krumbach Joseph
  • Nicholas Skaggs
  • Valorie Zimmerman

So once again, it’s time to get those sessions in.  Visit this page to learn how, then start thinking of what you want to talk about during those three days.  Help the track leads out by finding more people to propose more sessions, and let’s get that schedule filled out. I look forward to seeing you all at our first ever Ubuntu Online Summit.

I’ve just finished the last day of a week long sprint for Ubuntu application development. There were many people here, designers, SDK developers, QA folks and, which excited me the most, several of the Core Apps developers from our community!

image20140520_0048I haven’t been in attendance at many conferences over the past couple of years, and without an in-person UDS I haven’t had a chance to meetup and hangout with anybody outside of my own local community. So this was a very nice treat for me personally to spend the week with such awesome and inspiring contributors.

It wasn’t a vacation though, sprints are lots of work, more work than UDS.  All of us were jumping back and forth between high information density discussions on how to implement things, and then diving into some long heads-down work to get as much implemented as we could. It was intense, and now we’re all quite tired, but we all worked together well.

I was particularly pleased to see the community guys jumping right in and thriving in what could have very easily been an overwhelming event. Not only did they all accomplish a lot of work, fix a lot of bugs, and implement some new features, but they also gave invaluable feedback to the developers of the toolkit and tools. They never cease to amaze me with their talent and commitment.

It was a little bitter-sweet though, as this was also the last sprint with Jono at the head of the community team.  As most of you know, Jono is leaving Canonical to join the XPrize foundation.  It is an exciting opportunity to be sure, but his experience and his insights will be sorely missed by the rest of us. More importantly though he is a friend to so many of us, and while we are sad to see him leave, we wish him all the best and can’t wait to hear about the things he will be doing in the future.

Bicentennial Man PosterEver since we started building the Ubuntu SDK, we’ve been trying to find ways of bringing the vast number of Android apps that exist over to Ubuntu. As with any new platform, there’s a chasm between Android apps and native apps that can only be crossed through the effort of porting.

There are simple solutions, of course, like providing an Android runtime on Ubuntu. On other platforms, those have shown to present Android apps as second-class citizens that can’t benefit from a new platform’s unique features. Worse, they don’t provide a way for apps to gradually become first-class citizens, so chasm between Android and native still exists, which means the vast majority of apps supported this way will never improve.

There are also complicates solutions, like code conversion, that try to translate Android/Java code into the native platform’s language and toolkit, preserving logic and structure along the way. But doing this right becomes such a monumental task that making a tool to do it is virtually impossible, and the amount of cleanup and checking needed to be done by an actual developer quickly rises to the same level of effort as a manual port would have. This approach also fails to take advantage of differences in the platforms, and will re-create the old way of doing things even when it doesn’t make sense on the new platform.

Screenshot from 2014-04-19 14:44:22NDR takes a different approach to these, it doesn’t let you run our Android code on Ubuntu, nor does it try to convert your Android code to native code. Instead NDR will re-create the general framework of your Android app as a native Ubuntu app, converting Activities to Pages, for example, to give you a skeleton project on which you can build your port. It won’t get you over the chasm, but it’ll show you the path to take and give you a head start on it. You will just need to fill it in with the logic code to make it behave like your Android app. NDR won’t provide any of logic for you, and chances are you’ll want to do it slightly differently than you did in Android anyway, due to the differences between the two platforms.

Screenshot from 2014-04-19 14:44:31To test NDR during development, I chose the Telegram app because it was open source, popular, and largely used Android’s layout definitions and components. NDR will be less useful against apps such as games, that use their own UI components and draw directly to a canvas, but it’s pretty good at converting apps that use Android’s components and UI builder.

After only a couple days of hacking I was able to get NDR to generate enough of an Ubuntu SDK application that, with a little bit of manual cleanup, it was recognizably similar to the Android app’s.

This proves, in my opinion, that bootstrapping an Ubuntu port based on Android source code is not only possible, but is a viable way of supporting Android app developers who want to cross that chasm and target their apps for Ubuntu as well. I hope it will open the door for high-quality, native Ubuntu app ports from the Android ecosystem.  There is still much more NDR can do to make this easier, and having people with more Android experience than me (that would be none) would certainly make it a more powerful tool, so I’m making it a public, open source project on Launchpad and am inviting anybody who has an interest in this to help me improve it.

Ubuntu 14.04 will be released today and you couldn’t resist the itch to go try the Unity 8 preview session on the Desktop. How underwhelming… there are almost no apps, and some don’t even work and overall it’s actually pretty unexciting… let’s change that in the next few chapters. First things first though… let’s look […]
