Ubuntu App Developer Week - Day 4 Summary
Last day of UADW! While we're watching the final sessions, here's what happened yesterday:
Creating an App Developer Website: developer.ubuntu.com
By John Oxton and David Planella
Creating the concept and implementing a site for app developers is no easy task. The Ubuntu App Developer site is meant to be a place for app authors to get started with development, to find the information they need and to be able to publish their apps in the Software Centre. John explained all the research and user testing that happened behind the scenes, highlighting the key findings, while David focused on the purpose of the site, where it fits in the overall developer strategy for Ubuntu and the plans for the future.

Rapid App Development with Quickly
By Michael Terry
Fitting nicely topicwise with the questions about the default choice of tools for Ubuntu development on the previous session, Michael gave an overview of what Quickly is and how to use it. Going through the workflow of creating your first app with Quickly, he demonstrated all the key commands and explained in detail all the bits in between.

Developing with Freeform Design Surfaces: GooCanvas and PyGame
By Rick Spencer
Rick started off the session explaining what GooCanvas and PyGame were good for: providing a 2D surface on which to construct interactive GUIs for users. Beginning with GooCanvas, he showed with a very simple example how to get started playing with 2D composing surfaces, adding images, text and doing other operations such as resizing and calculating coordinates to determine clicks. Next up was PyGame, for the same purpose, but better suited for apps with lots of animation updates without user input. He then wrapped up with three samples of simple games to study.

Making your app appear in the Indicators
By Ted Gould
Ted Gould, the man who controls the upper right corner of our screen, talked all about indicators. The idea was to illustrate how to get the information that comes from applications and handle it to the indicators. First up was the messaging menu, a menu to handle human-to-human communication, next the application indicators, which alllow long-running apps to put statuses on the panel consistently, and finally the sound indicator, taking care of all related to sound. Each one of them explained with code examples. Nice!

Will it Blend? Python Libraries for Desktop Integration
By Marcelo Hashimoto
Marcelo shared his experience acquired with Polly, a Twitter client he developed, on using Python and libraries to let apps provide better integration to the desktop. First explaining the concept of desktop integration, stressing the fact that it's not only about visuals. The rest of the session was structured around 3 main areas: how to send notifications to the user, where to place files read or written by an app and what to use to store sensitive information. A very clear and solid session, also with example code for easy learning.

Closing the series of sessions around publishing apps in the Software Centre, we'll have the luxury of having John Pugh, from the team that brings you commercial apps into the Software Centre and who'll be talking about the business side of things.
20:00 UTC - Writing an App with Go
Go is the coolest kid around in the world of programming languages. Gustavo Niemeyer is very excited about it and will be showing you how to write an app using this language from Google. Be warned, his enthusiasm is contagious!
20:00 UTC - Qt Quick At A Pace
A last minute and very welcome addition to the schedule. In his session Donald Carr will introduce you to Qt Quick to create applications with Qt Creator and QML, the new declarative language that brings together designers and developers.
