Departments are a way for the user to navigate the data source exposed by a scope. A music scope can use them to allow browsing by genre, a Youtube scope could list channels and playlists, a news scope could use them for listing topics, etc. Departments can also display a full hierarchy of sub-departments.

In this tutorial, you are going to learn how to create and add them to your scope.

A scope is a tailored view for a set of data, that can use custom layouts, display and branding options. From RSS news feeds to weather data and search engine results, the flexibility of scopes allows you to provide a simple, recognizable and consistent experience with the rest of the OS.

Scopes can also integrate with system-wide user accounts (email, social networks…), split your content into categories and aggregate into each others (for example, a “shopping” scope aggregating results from several store scopes).

ubuntu-phone-three-1As we enter the final months before the first Ubuntu phones ship from our partners Meizu and Bq, the numbers of apps, users and downloads continues to grow at a steady pace. Today I’m excited to announce that we have more than ten thousand unique users of Ubuntu on phones or tablets!

Users

Ubuntu phone (and tablet) users sign into their Ubuntu One account on their device in order to download or update the applications on their phone. This allows us to provide many useful features that users expect coming from Android or iOS, such as being able to re-install their collection of apps on a new phone or after resetting their current one, or browsing the store’s website (coming soon) and having the option to install an app directly to their device from there. As a side effect, it means we know how many unique Ubuntu One accounts have connected to the store to in order to download an app, and that number has this week passed the 10,000 mark.

Excitement

Meizu-MX3Not only is this a milestone, but it’s down right amazing when you consider that there are currently no phones available to purchase with Ubuntu on them. The first phones from OEMs will be shipping later this year, but for now there isn’t a phone or tablet that comes with the new Ubuntu device OS on it. That means that each of these 10,000 people have purchased (or already had) either a supported Nexus device, or are using one of the community ports, and either wiped Android off them in favor of Ubuntu, or are dual booting. If this many people are willing to install the beta release of Ubuntu phone on their device, just imagine how many more will want to purchase a phone with Ubuntu pre-installed and with full support from the manufacturer.

Pioneers

In addition to users of Ubuntu phone, we’ve also seen a steady growth in the number of applications and application developers targeting Ubuntu phone and using the Ubuntu SDK. To celebrate them, we created Ubuntu App Pioneers page, and the first batch of Pioneers t-shirts are being sent out to those intrepid developers who, again, are so excited about a platform that isn’t even available to consumers yet that they’ve dedicated their time and energy into making it better for everyone.

Ubuntu has always been about breaking new ground. We broke the ground with the desktop back in 2004, we have broken the ground with cloud orchestration across multiple clouds and providers, and we are building a powerful, innovative mobile and desktop platform that is breaking ground with convergence.

The hardest part about breaking new ground and innovating is not having the vision and creating the technology, it is getting people on board to be part of it.

We knew this was going to be a challenge when we first took the wraps off the Ubuntu app developer platform: we have a brand new platform that was still being developed, and when we started many of the key pieces were not there such as a solid developer portal, documentation, API references, training and more. Today the story is very different with a compelling, end-to-end, developer story for building powerful convergent apps.

We believed and always have believed in the power of this platform, and every single one of those people who also believed in what we are doing and wrote apps have shared the same spirit of pioneering a new platform that we have.

As such, we want to acknowledge those people.

And with this, I present Ubuntu Pioneers.

The idea is simple, we want to celebrate the first 200 app developers who get their apps in Ubuntu. We are doing this in two ways.

Firstly, we have created http://developer.ubuntu.com/pioneers which displays all of these developers and lists the apps that they have created. This will provide a permanent record of those who were there right at the beginning.

Secondly, we have designed a custom, limited-edition Ubuntu Pioneers t-shirt that we want to send to all of our pioneers. For those of you who are listed on this page, please ensure that your email address is correct in MyApps as we will be getting in touch soon.

Thank-you so much to every single person listed on that page. You are an inspiration for me, my team, and the wider Ubuntu project.

If you have that pioneering spirit and wished you were up there, fear not! We still have some space before we hit 200 developers, so go here to get started building an app.

We’ve recently rolled out some changes to the submission process for Click Applications that should make it easier for you to submit new applications, and allow them to be approved more quickly.

Previously when submitting an application you would have to enter all the information about that application on the website, even when some of that information was already included in the package itself. This was firstly an irritation, but sometimes developers would make a mistake when re-entering this information, meaning that the app was rejected from review and they would have to go back and correct the mistake.

With the new changes, when you submit an application you will wait a few seconds while the package is examined by the system, and you will then be redirected to the same process as before. However this time some of the fields will be pre-filled with information from the package. You won’t have to type in the application name, as it will already be there. This will speed up the process, and should reduce the number of mistakes that happen at that stage.

We’ve also been working on a command-line interface for submitting applications. It’s not polished yet, but if you are intrepid you can try out click-toolbelt.

At the same time that Ubuntu 13.10 was released, we also went live with a new API documentation website here on the Ubuntu Developer Portal. This website will slowly replace our previous static docs, which came in a variety of formats, with a single structured place for all of our developer APIs. This new site, backed by Python and Django, will let us make our API documentation more easily discoverable, more comprehensive, and more interactive over time.

Screenshot from 2013-10-17 09:54:41

We launched the site with only the documentation for the Ubuntu UI Toolkit, as well as upstream QtQuick components. But in the past week we’ve added on to that API documentation for the new Content Hub, which allows confined apps to request access to files (pictures, music, etc) stored outside of their sandbox, as well as a full new section of HTML5 API docs covering the visual components developed to match the look and feel of their Qt/QML counterparts.

We’ve already written about Unity Technologies, supporting publishing applications to Linux in the next release of their platform, Unity 4.0. Canonical attended Unity’s Unite developer conference in Amsterdam, held 21-24 August, to meet with the nearly 1,200 Unity employees and developers and see first hand what to expect in Unity 4.0.

In Amsterdam, the Unite keynote kicked things off with an overview of the past few years and the evolution of Unity. Famed game designer Peter Molyneux, took to the stage and wowed the crowd with his latest game, the soon-to-be-renamed, Curiosity. The afternoon was filled with sessions geared towards developers who use Unity to create amazing games for all sorts of platforms. Thursday had a great session about how to use networking in Unity to create multiplayer games and how the new features in Unity 4.0 can make games come alive.

We already knew that Unity 4.0 is going to be unbelievable! The games that were showcased and won the Unity Awards really raised the bar for Unity development. You can get the lowdown on what Unity 4.0 has to offer, how to upgrade and what you need to run it from the FAQ. The free version of Unity 4.0 will, when released in a few months, include the new Mecanim engine and everything you need to start making incredible games right away. If you need a bit more power, additional effects, more streaming options and other tools, you’ll want to take a look at the Unity Pro 4.0 version. Either way free or pro, the great news is that publishing to Ubuntu is included.

On Friday, David Pitkin and I presented to a eager crowd about how Ubuntu and Unity’s new publish-to-Linux feature would open up their applications to millions of users who have a keen interest in getting their game on and buying games on Ubuntu machines. During and after the sessions we were bombarded with questions about how to get started with Ubuntu and submission requirements for the Ubuntu Software Center. We can’t wait for so many awesome games to arrive on Ubuntu in the coming months.

We had a great time at Unite, met some wonderful developers, played some excellent games, and got the word out on Ubuntu Software Center and publishing games to millions of Ubuntu users.
