Quick overview post today, because it’s late and I don’t have anything particular to talk about today.

First of all, the next vUDS was announced today, we’re a bit late in starting it off but we wanted to have another one early enough to still be useful to the Trusty release cycle.  Read the linked mailinglist post for details about where to find the schedule and how to propose sessions.

I pushed another update to the API website today that does a better job balancing the 2-column view of namespaces and fixes the sub-nav text to match the WordPress side of things. This was the first deployment in a while to go off without a problem, thanks to  having a new staging environment created last time.  I’m hoping my deployment problems on this are now far behind me.

I took a task during my weekly Core Apps update call to look more into the Terminal app’s problem with enter and backspace keys, so I may be pinging some of you in the coming week about it to get some help.  You have been warned.

Finally, I decided a few weeks ago to spread out my after-hours community a activity beyond Ubuntu, and I’ve settled on the Debian new maintainers Django website as somewhere I can easily start.  I’ve got a git repo where I’m starting writing the first unit tests for that website, and as part of that I’m also working on Debian packaging for the Python model-mommy library which we use extensively in Ubuntu’s Django website. I’m having to learn (or learn more) Debian packaging, Git workflows and Debian’s processes and community, all of which are going to be good for me, and I’m looking forward to the challenge.

We wrapped up the last day of our sprint with a new team photo.  I can honestly say I couldn’t think of a better group of people to be working with.  Even the funny looking guy in the middle.

I mentioned that earlier in the week we decided on naming SDK releases after distro releases, and with that information in hand I spent my last day getting the latest API docs uploaded, so if you’re writing apps for the latest device images, you’ll want to use these: http://developer.ubuntu.com/api/qml/sdk-14.04/

In the coming week I’ll be working to get the documentation publishing scripts added to the automated build and testing process, so those docs will be continuously updated until the release of Ubuntu 14.04, at which point we’ll freeze those doc pages and start publishing daily updates for 14.10.  Being able to publish  all of those docs in a matter of minutes was a particularly thrill for me, after working for so long to get that feature into production.  It certainly proves that it was the right approach.

Second to last day of the sprint, and we’ve been shifting gears from presenting ideas and brainstorming to making solid plans and bringing all the disparate pieces together.  The result is looking very, very promising.

I started out this morning by updating my Nexus 4 to build 166, which brings some improvements to the Unity 8 and system apps.  I’m still poking around to discover what’s new.

I had a handful of great conversations with the Jamie (security) and Ken (content-hub) about how to deliver creative content via click packages in the new store.  It looks like wallpapers will be relatively easy to support, and Ken and I (mostly Ken) will be working on adding that to the Click installer and System Settings.  Theme support is unfortunately going to be more difficult, since our QML themes are full QML themselves, and can run their own code, which makes them a security concern. We’re going to try and support a safe subset of styling to be delivered via Click packages, but that’s not likely to happen this cycle.

After lunch we had another set of presentations, this time from Florian Boucault on the SDK team about app performance.  After briefly covering performance goals we need to meet to make our UI as smooth and responsive an iOS, he stunned us all by showing off live performance graphs overlaid on top of one of the Core Apps (sadly I didn’t get a picture of that) so you can see the CPU and GPU usages while interacting with the app.  This wonderful little piece of magic should be landing in device images in the next couple of weeks, and I for one can not wait to try it out. In the mean time, he was nice enough to sit down with me and walk me through using QtCreator’s Analyse tab to see what parts of my own app might be using more resources than then should.

Among the sessions I wasn’t able to attend today: More HTML5 device APIs are coming online, contacts syncing via the Online Accounts provider for Google got it’s first cut, the SDK’s StateSaver component got some finishing work done, and AppArmor optimizations that will speed up boot times.

Today we had a lot of good discussions around app development, starting off with an update on the state of GoLang support and what was needed to get the Go/QML bridge packaged and available for people to start using.

From there we moved on to the future of Content Hub, which is really set to reach it’s full potential now and we will hopefully see a wide range of system, core and 3rd party apps providing it with content.

After lunch Nick gave us all a quick lesson in how to properly use Autopilot, something I think we’re all going to become more familiar with in the coming months.  The key takeaway: Don’t Sleep.

Then we discussed QtCreator itself, and our various plugins for it.  We identified some easy fixes, and did a lot of brainstorming on how to attack the harder ones.  We saw the new packaging and cross-compilation support that’s being added to it now. Zoltan topped it all off by giving us a very short demonstration, going from the creation of a new project all the way, through creating a package, running package verification tests on it, copying it onto a phone and installing it, all in about 30 seconds!

We also discovered that the current SDK packages in the PPA were broken for Saucy and older releases (Trust was okay).  Daniel, Zoltan and David Barth spent much of the day intensely debugging the problem, providing a fix, shepherding those fixes though Launchpad and into the PPAs so that we could get it all working by the end of the day.  We then set aside time for a new session where we discussed what happened and what we can do to prevent it from happening again.  I’m pleased to say that some of those steps have already been implemented, and the rest will soon follow.

Finally we wrapped up the evening with chicken wings and beer, plus another fantastically entertaining card game courtesy of Alan Pope’s deranged humor.

Another day packed with meetings and discussions today.  Here’s some of the highlights:

We decided that SDK version numbering should mirror distro numbering, so instead of Ubuntu SDK 2.0 we will have Ubuntu SDK 14.04.

We worked out more details on the next App Developer Showdown, including what additions and changes to the SDK and store will be ready for the contest, and what prizes we will try to get for it.

After reviewing the current documentation on developer.ubuntu.com, we identified some areas where we need to improve it before the App Showdown.

Alan Pope and I guest starred in Jono’s weekly Q&A session, from the hotel bar, which was loads of fun.  Watch the full video to hear more about what we’ve been discussing here and maybe find answers to some of your own questions.

As I mentioned in my last post, I’m with the rest of my team in Orlando this week for a sprint. We are joined by many other groups from Canonical, and unfortunately we didn’t have enough meeting rooms for all of the breakout session, so the Community team was forced (forced I tell you) to meet on the patio by the pool.

We have had a lot of good discussions already, and we have four days left.  You’ll start to seem some of the new ideas and changes going into effect next week.  Until then, stay tuned.

Last week I posted on G+ about the a couple of new sets of QML API docs that were published.  Well that was only a part of the actual story of what’s been going on with the Ubuntu API website lately.

Over the last month I’ve been working on implementing and deploying a RESTful JSON service on top of the Ubuntu API website, and last week is when all of that work finally found it’s way into production.  That means we now have a public, open API for accessing all of the information available on the API website itself!  This opens up many interesting opportunities for integration and mashups, from integration with QtCreator in the Ubuntu SDK, to mobile reference apps to run on the Ubuntu phone, or anything else your imagination can come up with.

But what does this have to do with the new published docs?  Well the RESTful service also gives us the ability to push documentation up to the production server, which is how those docs got there.  I’ve been converting the old Django manage.py scripts that would import docs directly into the database, to instead push them to the website via the new service, and the QtMultimedia and QtFeedback API docs were the first ones to use it.

Best of all, the scripts are all automated, which means we can start integrating them with the continuous integration infrastructure that the rest of Ubuntu Engineering has been building around our projects.  So in the near future, whenever there is a new daily build of the Ubuntu SDK, it will also push the new documentation up, so we will have both the stable release documentation as well as the daily development release documentation available online.

I don’t have any docs yet on how to use the new service, but you can go to http://developer.ubuntu.com/api/service/ to see what URLs are available for the different data types.  You can also append ?<field>=<value> keyword filters to your URL to narrow the results.  For example, if you wanted all of the Elements in the Ubuntu.Components namespace, you can use http://developer.ubuntu.com/api/service/elements/?namespace__name=Ubuntu.Components to do that.

That’s it for today, the first day of my UbBloPoMo posts.  The rest of this week I will be driving to and fro for a work sprint with the rest of my team, the Ubuntu SDK team, and many others involved in building the phone and app developer pieces for Ubuntu.  So the rest of this week’s post may be much shorter.  We’ll see.

Happy Hacking.

Although I still use my desktop replacement (i.e., little-to-no battery life) for a good chunk of my work, recent additions to my setup have resulted in some improvements that I thought others might be interested in.

For Christmas just gone my wonderful wife Suzanne – and my equally wonderful children, but let’s face it was her money not theirs! – bought me a HP Chromebook 14. Since the Chromebooks were first announced, I was dismissive of them, thinking that at best they would be a cheap laptop to install Ubuntu on. However over the last year my attitudes had changed, and I came to realise that at least 70% of my time is spent in some browser or other, and of the other 30% most is spent in a terminal or Sublime Text. This realisation, combined with the improvements Intel Haswell brought to battery life made me reconsider my position and start seriously looking at a Chromebook as a 2nd machine for the couch/coffee shop/travel.

I initially focussed on the HP Chromebook 11 and while the ARM architecture didn’t put me off, the 2GB RAM did. When I found the Chromebook 14 with a larger screen, 4GB RAM and Haswell chipset, I dropped enough subtle hints and Suzanne got the message. :-)

So Christmas Day came and I finally got my hands on it! First impressions were very favourable: this neither looks nor feels like a £249 device. ChromeOS was exactly what I was expecting, and generally gets out of my way. The keyboard is superb, and I would compare it in quality to that of my late MacBook Pro. Battery life is equally superb, and I’m easily getting 8+ hours at a time.

Chrome – and ChromeOS – is not without limitations though, and although a new breed of in-browser environments such as Codebox, Koding, Nitrous.io, and Cloud9 are giving more options for developers, what I really want is a terminal. Enter Secure Shell from Google – SSH in your browser (with public key authentication). This lets me connect to any box of my choosing, and although I could have just connected back to my desk-bound laptop, I would still be limited to my barely-deserves-the-name-broadband ADSL connection.

So, with my Chromebook and SSH client in place, DigitalOcean was my next port of call, using their painless web interface to create an Ubuntu-based droplet. Command Line Interfaces are incredibly powerful, and despite claims to the contrary most developers spending most of their time with them1. There are a plethora of tools to improve your productivity, and my three must-haves are:

With this droplet I can do pretty much anything I need that ChromeOS doesn’t provide, and connect through to the many other droplets, linodes, EC2 nodes, OpenStack nodes and other servers I use personally and professionally.

In some other posts I’ll expand on how I use (and – equally importantly – how I secure) my DigitalOcean droplets, and which “apps” I use with Chrome.


  1. The fact that I now spend most of my time in the browser and not on the command-line shows you that I’ve settled into my role as an engineering manager! :-)

I was browsing Twitter last night when Thoughbot linked to their post about commit messages.

This was quite timely as my team has been thinking about improving the process of creating our release notes, and it has been proposed that we generate them automatically from our commit messages. This in turn requires that we have commit messages of sufficient quality, which – to be honest – we don’t always. So the second proposal is to enforce “good” commit messages as part of reviewing and approving merge proposals into our projects. See this post from Kevin on my team for an overview of our branching strategies to get an idea of how our projects are structured.

We still need to define what constitutes a “good” message, but we will certainly use both the article from Thoughtbot and the oft-referenced advice from Tim Pope as our basis. We are also only planning to apply this to commits to trunk because, well, you don’t need a novel – or even a short story – for every commit in your spike branch!

Now, back to the Thoughtbot article, and this piece of advice stood out for me:

Never use the -m <msg> / --message=<msg> flag to git commit.

Since I first discovered -m I have used it almost exclusively, thinking I’m being so clever and efficient, but in reality I’ve been restricting what I could say to what felt “right” on an 80 character terminal. If nothing else, I will be trying to avoid the use of -m from now on.

Do you want a new OPPO Find 5?  Of course you do!  Well the awesome team at OPPO have given us a brand new Find 5 (x909 to be exact) for us to give you.  So here’s the deal, the first person to provide a working Ubuntu Touch image for this device gets to keep it.

Last weekend both Ubuntu and OPPO had booths at the first ever XDA Developers Conference in Miami.  While discussing both of our new products, the idea came up to hold a porting contest to get Ubuntu Touch running on the Find 5.  Jono announced the initial contest during his presentation on Saturday, with an initial challenge to have a winner claim the prize during the conference itself.  Despite having three separate developers build images and flash them onto the phone, none were able to boot into Ubuntu Touch.

So now we’re extending the contest and making it available to everybody!  To enter, you will need to send me an email containing links to the necessary files and detailed step-by-step direction for loading them on the phone.  I don’t have much experience with flashing ROMs, so treat me like a complete newbie when writing your instructions.  If your images don’t work, I will send you the output from adb logcat as well as any other information you request.  If your images do work, and meet the requirements below, I’ll be asking for a mailing address so I can send you your prize!

In order to win your phone, you need to get Ubuntu Touch running on the OPPO Find 5. Not just booting, but running, and is a way that makes it usable for other Find 5 owners.  So I’ve set out the following things that I will be checking for:

  • The phone boots into Ubuntu Touch (obviously)
  • I can launch multiple apps and switch between them
  • I can make phone calls (I have a SIM that works)
  • I can send and receive SMS
  • I can connect to Wifi, using WPA2
  • The screen goes to sleep when pressing the power button or after the set timeout period, and wakes up again when pressing the power button
  • I can play audio with the Music app
  • I can take pictures with the front and rear cameras

So, you want to take a crack at it?  Well the first step is to read the Ubuntu Touch Porting Guide.  Once you have an image you want me to try, send an email to mhall119@gmail.com with “OPPO” somewhere in the subject (just to help me out, I get a lot of email).  In that email include all of the steps necessary to download and install your image.  Again, be detailed, I’m a newb.  If you image meets the above requirements, I’ll put it in the mail to you!  After that, we can work on getting your image available for easy installation via our phablet-flash tool, so all the other OPPO Find 5 owners can try it too.

When we announced the Ubuntu Edge crowd-funding campaign a week ago, we had one hell of a good first day.  We broke records left and right, we sold out of the first round of perks in half the time we expected, and we put the campaign well above the red line we needed to reach our goal.  Our second day was also amazing, and when we opened up a new round of perks at a heavy discount the third day we got another big boost.

But as exciting and record-breaking as that first week was, we couldn’t escape the inevitable slowdown that the Kickstarter folks call “the trough“.  Our funding didn’t stop, you guys never stopped, but it certainly slowed way down from it’s peak.  We’ve now entered a period of the crowd-funding cycle where keeping momentum going is the most important thing. How well we do that will determine whether or not we’re close enough to our goal for the typical end-of-cycle peak to push us over the edge.

And this is where we need our community more than ever, not for your money but for your ideas and your passion.  If you haven’t contributed to the campaign yet, what can we offer that would make it worthwhile for you?  If your friends haven’t contributed yet, what would it take to make them interested?  We want to know what perks to offer to help drive us through the trough and closer to the Edge.

Our Options

So here’s what we have to work with.  We need to raise about $24 million by the end of August 21st.  That’s a lot, but if we break it down by orders of magnitude we get the following combinations:

  • 1,000,000 people giving $24 each
  • 100,000 people giving $240 each
  • 10,000 people giving $2,400 each
  • 1,000 people giving $24,000 each

Now finding ways to get people to contribute $24 are easy, but a million people is a lot of people.  1,000 or even 10,000 people isn’t that many, but finding things that they’ll part with $2,400 for is challenge, even more so for $24,000.

That leaves us with one order of magnitude that I think makes sense. 100,000 people is a lot, but not unreasonable.  Previously large crowd-funding campaigns have reached 90,000 contributors, while raising only a fraction of what we’re trying for, so that many people is an attainable goal.  Plus $240, while more than an impulse purchase, still isn’t an unreasonable amount for a lot of people to part with, especially if we’re giving them something of similar real value in return.

Now it doesn’t have to be exactly $240, but think of perk ideas that would be around this level, something less than the cost of a phone, but more than the Founder levels.

Our Limits

Now, for the limitations we have.  I know everybody wants to see $600 phones again, and that would certainly be an easy way to boost the campaign.  But the manufacturing estimate we have is that $32 million will build only 40,000 phones.  That’s $800 per phone.  That’s something we can’t get away from.  Whatever we offer as perks, we have to average at least $800 per phone.  We were able to offer perks for less than that because we projected the other perk levels to help make up the difference.  So if you’re going to suggest a lower-priced phone perk, you’re going to have to offer some way to make up the difference.

You also need to consider the cost of offering the perk, as a $50 t-shirt doesn’t actually net $50 once you take out the cost of the shirt itself, so we can’t offer $240 worth of merchandise in exchange for a $240 contribution. But you could probably offer something that costs $20 to make in exchange for a $240 contribution.

Our Challenge

So there’s the challenge for you guys.  I’ve been thinking of this for over a week now, and have offered my ideas to those managing the campaign.  Often they pointed out some flaw in my reasoning or estimates, but some ideas they liked and might try to offer.  I can’t promise that your ideas will be offered, but I can promise to put them in front of the people making those decisions, and they are interested in hearing from you.

Now, rather than trying to cultivate your ideas here on my blog, because comments are a terrible place for something like that, I’ve created a Reddit thread for you.  Post your ideas there as comments, upvote the ones you think are good, downvote the ones you don’t think are possible, leave comments and suggestions to help refine the ideas.  I will let those running the campaign know about the thread, and I will also be taking the most popular (and possible) ideas and emailing them to the decision makers directly.

We have a long way to go to reach $32 million, but it’s still within our reach.  With your ideas, and your help, we will make it to the Edge.

As part of our self-improvement and knowledge sharing within Canonical, within our group (Professional and Engineering Services) we regularly – at least once a month – run what we call an “InfoSession”. Basically it is Google Hangout on Air with a single presenter on a topic that is of interest/relevance to others, and one of my responsibilities is organising them. Previously we have had sessions on:

  • Go (a couple of sessions in fact)
  • SystemTap
  • Localization (l10n) and internationalization (i18n)
  • Juju
  • Graphviz
  • …and many others…

Today the session was on continuous integration with Tarmac and Vagrant, presented by Daniel Manrique from our certification team. In his own words:

Merge requests and code reviews are a fact of life in Canonical. Most projects start by manually merging approved requests, including running a test suite prior to merging.

This infosession will talk about tools that automate this workflow (Tarmac), while leveraging your project’s test suite to ensure quality, and virtual machines (using Vagrant) to provide multi-release, repeatable testing.

Like most of our sessions it is publicly available, here it is is for your viewing pleasure:

There’s been a lot of talk about the Ubuntu Edge, and our associated Indiegogo campaign to fund it. There has been a lot of positive coverage on news sites, social media, Reddit and even one television interview. But there have also been a lot of questions about why we’re doing this, and why we’ve chosen a crowd-funding campaign to do it. Since I’ve seen so many of the same questions being asked by so many people, I wanted to take the time to try and explain things a little bit better.

What it isn’t

In order to fully understand and appreciate what the campaign is about, it might be easiest to first explain fully what it isn’t.  Once we’ve done away with these misconceptions, it should become more clear why it is what it is, and finally why that is important.

First of all, and perhaps most importantly, this is not a charity.  We have provided a $20 perk for people who want to see this campaign succeed but don’t have the means or desire to purchase one of the Ubuntu Edge devices.  But this is primarily a way for people to get very high-end hardware by paying for it’s creation.  I don’t have the exact numbers, but just going by what we’ve seen of the perks claimed, people have been contributing at levels that would get them a phone more than 3.5 times more often than the much less expensive founder’s perk. This tells me that people aren’t supporting this campaign because they think it’s a good cause, or because they like what Canonical is doing, by and large they are supporting this campaign because they want an Ubuntu Edge in return.

Secondly, and this is one that has been asked a lot, this is not a financial investment.  OEMs aren’t stupid, venture capitalists aren’t stupid, and Mark Shuttleworth isn’t stupid.  If there was money to be made in building bleeding-edge phones then we would have half a dozen to choose from at our local store.  The margins on hardware sales is much lower than many people realize, and without a high rate of profits available, only a very low level of risk can be assumed.  That’s the main reason nobody else has built a phone like the Ubuntu Edge, and why nobody is going to anytime soon if we were to try and do it using capital investments.  The Ubuntu Edge doesn’t need to prove that people want scratch-proof screens or high-capacity batteries, it doesn’t need to prove that consumers like more power and more storage, it needs to prove that those technologies are ready to be produced in high volumes without supply or manufacturing problems.  It doesn’t need to prove that people want a desktop available at home or work, but it does need to prove that the hardware and software are capable now of providing that convergence in a satisfactory way that previous attempts couldn’t.

Finally, it’s not a way of making money for Canonical or a last-ditch effort for keeping either Ubuntu or Ubuntu Touch alive.  Whether this campaign succeeds or fails, we will continue to work with OEMs to bring multiple consumer phones to market, most likely using slightly better hardware than the current generation of smart phones, where there is little risk involved on the hardware side.  But in order for Ubuntu to provide the kind of convergence and one-device experience that we envision, we needed skip the slow, safe evolution of hardware and spark the flames on a whole new class of phone.  So while we work on getting Ubuntu phones to market with our partners, the Ubuntu Edge will provide the seeds for the suppliers and manufacturers that those partners use, so they will be ready to build their new generation of superphones when the time comes.

What it is

Now that I’ve gone over what this campaign isn’t, let talk about what it is.  I spent some time over this weekend thinking about how to accurately describe it without going deep into the economics or politics of it, trying to find parallels in other industries (like Mark’s F-1 analogy) that wouldn’t fall apart when going into the specifics of either.  In the end, I decided that the thing this campaign resembles the most is an adventure.

Now that’s vague, I know, so let me give some more concrete examples.  I liked Mark’s F-1 analogy, but when looking into how F-1 actually operates these days it really doesn’t quite fit.  Instead it’s more like X-Prize competition that put the first private manned vehicle into space.  Even though there was a monetary prize in that competition, it was only a tiny fraction of the money that went into building any of the entrants.  The reason anybody participated was to push the bounds of technology and to try and birth a new industry, one where they would stand to benefit more in the long run than any possible profits they could have made by sticking with the status quo.

But those initiatives were largely funded by wealthy individuals, who probably didn’t expect to get much in return.  So for a more fitting analogy we need to go a bit further back in time, to expeditions into the Americas and Africa, some of which were funded only by those who were to participate in them, and who could expect little more than the thrill of participating.  While not pushing the limits of technology, these adventurers would certainly push the bounds of knowledge to new levels, and would fundamentally change the way the world looked.

[Update] It has been pointed out in the comments that many of these expeditions had either deplorable intents or disasterous consequences for the native people.  While this was not at all what I had in mind, I understand that my knowledge of those histories is largely influenced by my own ancestry.  A better example, as also pointed out in the comments, would be the expeditions to both the north and south poles, or the scaling of Everest.

Why it’s important

Now both of these are extreme examples, and certainly far outshine what we’re trying to do with the Ubuntu Edge.  It is just a computer after all.  But on a smaller scale the reasons and motivations are the same, there is a desire to push the limits that currently confine us.  And that’s certainly not a feeling that’s limited to Canonical, over 15,000 people have contributed to the campaign in one way or another, and around 10,000 have committed to sharing the adventure with us from the beginning by claiming their own phone.  These aren’t wealthy investors looking to become more wealthy, nor is it good-hearted folks who are giving us money just to be nice, these are thousands of people who want go on the adventure because it’s exciting, because it’s audacious, and because it gives them the future they want to see made.

So there it is, we’re embarking on an adventure, and we want you to come with us.  If the Ubuntu Edge makes you excited for the future of computing, if you’re eager to see that future technology years before it becomes common place, if you want be on of the ones cutting new trails rather than following those well-worn paths cut years ago, then I invite you to sign up and add your name to the list of technology pioneers.

Yesterday I posted the first in a new series of Core App Update, featuring the Clock App’s development.  Today I’m going to cover the status of the Calendar

Calendar Features

Calendar View

The calendar now provides several different views you can choose from.  You start off with a full month at the top, and your events for the day below.  Swiping left and right on the month will take you back or forward a month at a time.  Swiping left or right on the bottom half will take you back and forward a day at a time.

Pull the event area down and let it go, and the month will collapse down into a single week. Now swiping left and right there will move you back and forward a week at a time.  Pull down and let it go again and it will snap back to showing the full month.

Finally, you have an option in the toolbar (swipe up from the bottom edge) to switch from an event list to a timeline view of your events.

Adding Events

You can current add events to the calendar app, and they will be stored in a local database.  However, after discussions with Ubuntu Touch developers, the Calendar team is refactoring the app to use the Qt Organizer APIs instead.  This will allow it to automatically support saving to Evolution Data Server as a backend as soon as it’s integrated, making calendar events available to other parts of Ubuntu such as the datetime indicator.  Being able to import your ical feeds is also on the developer’s TODO list.

Visual Designs

We don’t have new visual designs for the Calendar yet, but it is one of the apps that the Design team has committed to providing one for.  Now that they are done with the Clock’s visual designs, I hope to see these soon for the Calendar.

Release Schedule

Once again I worked with the Calendar developers to set release targets for their app.  The alpha release is targeted for month-2, this month, and should include the switch to Qt Organizer.  Then we plan on having a Beta release in August and a Final in September.

The Ubuntu Touch Core Apps project is a new kind of collaboration between Canonical and the wider Ubuntu community, with a goal of developing high-quality applications for Ubuntu Touch. A couple of months ago I set out the Core Apps roadmap to October, and it’s high time I got around to giving you an update on our progress.

I had originally planned on giving an update of each of the core apps in a single blog post, but I realized that was going to get very, very long.  And nobody has time to read a giant wall of text.  So instead I’ll be breaking them up, one post per apps, so you can spread your reading time over multiple days.

To kick this off, here are the latest developments going on in the Clock app:

Clock Features

Sunrise & Sunset

Recently added to the main Clock tab is a way to check the sunrise and sunset times for the day.  Simply tap on the clock face and it will switch to the sunrise/sunset view.  Tap it again to switch back.  Swipe up from the bottom to reveal the toolbar, where you can set your location (which is used to calculate your specific sunrise and sunset times).

Alarms

The Clock app developers are still waiting on a platform API to support registering alarms that will work even when the Clock app isn’t running.  But while they’re waiting on that, they’ve still be working hard on the interface for managing your alarms.  Their approach is both minimal and obvious, you drag the hour and minute hands around to the time you and and click Done in the center.  If you need more options, you can pick how often to repeat, what alarm tone to use, and whether or not to vibrate.

Now these won’t actually work until the platform API is in place, but you can already see how it will look to the user, and how simple it is to do.

Timer

Like the alarms, setting a timer is both minimal and obvious.  Unlike alarms, the timer is working today.  Drag the hand around to set how many seconds, tap the minutes part of the time and drag the hand to set the minutes.  Make more than one revolution around the dial and it will start adding hours as well.

Another nice feature is the ability to define custom timers that you can use again and again.  Swipe up from the bottom to reveal the toolbar again, select Add Preset, and set the duration using the same simple dragging motions on the dial.

Stopwatch

Finally we come to the stopwatch part of the app.  In addition to simple start, pause and reset functionality, the stopwatch lets you mark laps as it goes, and keeps a log of each one that you can view both while the stopwatch is running and after.

Visual Designs

Some of you may have seen the new visual concepts that the Design Team published last month, which received quite a bit of positive feedback.  Well this week they sent the Clock developers the completed visual designs for the Clock app, so we should start to get our first taste of those designs in action in the next few weeks.

Release Schedule

Starting a couple of weeks ago, I started working with each of the Core Apps developer teams to set release targets for Alpha, Beta and Final releases of the app, with a goal to have them all at a 1.0 version before the October release of Ubuntu 13.10.  For the clock, we decided to mark the month-1 milestone (May) as an alpha release, because of the progress they had already made.  We then picked month-3 (July) for beta and month-4 (August) for our final release target.  Furthermore we have work items assigned on a monthly release basis to track the progress we are making.
