Scopes come with a very flexible customization system. From picking the text color to rearranging how results are laid out, a scope can easily look like a generic RSS reader, a music library or even a store front.

In this new article, you will learn how to make your scope shine by customizing its results, changing its colors, adding a logo and adapting its layout to present your data in the best possible way. Read…

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 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.

App Showdown Winners

The judging is finished and the scores are in, we now have the winners of this year’s Ubuntu App Showdown!  Over the course of six weeks, and using a beta release of the new Ubuntu SDK, our community of app developers were able to put together a number of stunningly beautiful, useful, and often highly entertaining apps.

We had everything from games to productivity tools submitted to the competition, written in QML, C++ and HTML5. Some were ports of apps that already existed on other platforms, but the vast majority were original apps created specifically for the Ubuntu platform. Best of all, these apps are all available to download and install from the new Click store on Ubuntu phones and tablets, so if you have a Nexus device or one with a community image of Ubuntu, you can try these and many more for yourself.  Now, on to the winners!

Original Apps #1: Karma Machine

karma_machine_subredditkarma_machine_contentkarma_machine_commentsKarma Machine is wonderful app for browsing Reddit, and what geek wouldn’t want a good Reddit app?  Developed by Brian Robles, Karma Machine has nearly everything you could want in a Reddit app, and takes advantage of touch gestures to make it easy to upvote and downvote both articles and comments.  It even supports user accounts so you can see your favorite subreddits easily.  On top of it’s functionality, Karma Machine is also visually appealing, with a good mix of animations, overlays and overall use of colors and layouts.  It is simply one of the best Reddit clients on any platform (having written my own Reddit client, that’s saying something!), and having it as an original Ubuntu app makes it a valuable addition to our ecosystem.  With all that, it’s little wonder that Karma Machine was tied for the top spot on the judges list!

Original Apps #1: Saucy Bacon

saucy_bacon_searchsaucy_bacon_toolbarsaucy_bacon_editSomething for the foodies among us, Saucy Bacon is a great way to find and manage recipes for your favorite dish. Backed by food2fork.com, this app lets you search for recipes from all over the web.  You can save them for future reference, and mark your favorites for easy access over and over again.  And since any serious cook is going to modify a recipe to their own tastes, Saucy Bacon even lets you edit recipes downloaded from somewhere else.  You can of course add your own unique recipe to the database as well.  It even lets you add photos to the recipe card directly from the camera, showing off some nice integration with the Ubuntu SDK’s sensor APIs and hardware capabilities.  All of this mouth-watering goodness secured developer Giulio Collura’s Saucy Bacon app a tie for the #1 stop for original Ubuntu apps in our contest.

Ported Apps #1: Snake

snake_introsnake_play2snake_play

The game Snake has taken many forms on many platforms throughout the years.  It’s combination of simple rules and every-increasing difficulty has made it a popular way to kill time for decades.  Developer Brad Wells has taken this classic game from Nokia’s discontinued Meego/Harmattan mobile OS, which used a slightly older version of Qt for app development, and updated it to work on Ubuntu using the Ubuntu SDK components.  Meego had a large number of high quality apps written for it back in it’s day, and this game proves that Ubuntu for phones and tablets can give those apps a new lease on life.

Go and get them all!

The 2013 Ubuntu App Showdown was an opportunity for us to put the new Ubuntu SDK beta through some real-world testing, and kick off a new app ecosystem for Ubuntu.  During the course of these six weeks we’ve received great feedback from our developer community, worked out a large number of bugs in the SDK, and added or plan to add many new features to our platform.

In addition to being some of the first users of the Ubuntu SDK, the app developers were also among the first to use the new Click packaging format and tools as well as the new app upload process that we’ve been working on to reduce review times and ease the process of publishing apps.  The fact that all of the submitted apps have already been published in the new app store is a huge testament to the success of that work, and to the engineers involved in designing and delivering it.

Once again congratulations to Brian Robles, Giulio Collura and Brad Wells, and a big thank you to everybody who participated or helped those who participated, and all of the engineers who have worked on building the Ubuntu SDK, Click tools and app store.  And if you have a supported device, you should try out the latest Ubuntu images, and try these and the many other apps already available for it.  And if you’re an app developer, or want to become an app developer, now is your time to get started with the Ubuntu SDK!

Yesterday we released Ubuntu Touch Preview images for four devices. This is a huge milestone for Ubuntu. We always wanted Ubuntu to be everywhere and the Preview shows quite nicely how well the vision of a design family across different form factors works.

There is quite a bit of work to be done, we all know that, but it’s a giant opportunity for us, the Ubuntu community. Everybody can contribute to the effort and we can show the world how we believe software should look like.

How you can help? Easy.

  • You can install the Ubuntu Touch preview images on a device and test them.
  • You can help out designing and shaping the Ubuntu Touch Core Apps.
  • If you are a bit more experienced with bringing software up on new devices, you can help us porting Ubuntu Touch to new devices.

Did the last point find your interest? Excellent, because we just took the wraps of our Ubuntu Touch Porting guide. This also marks the start of our Ubuntu Touch Port-a-thon. We want to get Ubuntu Touch up and running on as many devices as possible.

If you don’t mind some tinkering, maybe some kernel building, some configuration meddling and flashing your device repeatedly, you might just the person we’re looking for.

The porting guide should help you understand

  • how Ubuntu Touch works internally,
  • which bits are generally involved and where to find them
  • how to submit patches
  • how images are put together
  • how to test them and
  • where to find help

To get you started and into the mood, you might want to join us today, at Friday 22nd February at 15:00 UTC on http://ubuntuonair.com when two super heroes of the Ubuntu Touch project, namely Ricardo Salveti and Sergio Schvezov, are going to talk to us about the technical aspects of the phone and the tablet.

Reliable sources tell us, there’s going to be a surprise announce during the hangout as well.

This is the opportunity we always wanted. Let’s make it happen. Bring Ubuntu to the world in all its beauty.

Things are really ramping up with submissions into the Ubuntu Software Center. With a app per day being submitted, the packaging team is getting busy keeping up with the cool applications arriving!

TRAUMA is likely the most interesting new submission. Very unique. You are in the mind of a traumatized young woman as she has just been in a car accident. You experience her dreams in a interactive way.

Check out the trailer:

Buy TRAUMA from the Ubuntu Software Center.

Books and Magazines

We also added some magazines to the mix. Several recent issues of Ubuntu User magazine by Linux New Media are available on the Software Center. You can find the most recent issues up through Ubuntu User issue #9 which has a section dedicated to Ubuntu 11.04 and Unity. Keep your eyes peeled for book titles about Linux and Ubuntu arriving soon.

Photobomb

Another really interesting title recently released is called Photobomb. It’s described as a “Easy and Social Image Editor”. It’s like a mashup tool for your images. Pretty slick and at $2.99 it’s a cinch to check out. Go buy it and provide some feedback today.

We have some very cool submissions pending the packaging process in the queue. Thanks to all of our interested developers out there we have officially backed up the packaging team! Don’t worry though…we’ll soon work through that backlog and have a lot of new and interesting titles showing up regularly in the software center.

Check them out, provide some feeback, and even submit more!
To submit a new application go to https://myapps.developer.ubuntu.com

And one last thing – keep your eye out for the updated developer.ubuntu.com website coming in early October!
