Ubuntu Developer Week: Review of Day 2, Outlook: last day

Ubuntu Developer Week is passing by much too quickly, as always. Still it’s great to see how many new people get involved, find out more about Ubuntu Development and get involved. Day 2 was yesterday and brought us many great sessions. Here’s what happened yesterday:

  1. How to write apps for Ubuntudpm: David Planella was well prepared as always and gave some good insights into what it takes to take an app from idea to a working app. He got quite a number of questions during the session, so I guess we can expect more apps coming to Ubuntu soon. 🙂
  2. Ubuntu App review process explainedcoolbhavi: Bhavani Shankar explained the next step in terms of apps and demonstrated how a typical App Review works. Unfortunately the session was interrupted by a bot misbehaving towards the end, but lots of questions were still answered.
  3. Finding memory leaksachiang (Hangout!): Memory leaks can become huge problems in no time, and sometimes it’s not easy to debug or fix them. Alex Chiang is passionate about fixing them and provided a great session about how and where to start.
  4. Testing with autopilotballoons: Nicholas Skaggs and Thomi Richards are becoming the autopilot double-act (you will likely see them in tomorrow’s Automated Testing Hackfest as well). They gave a very nice introduction into autopilot and how to use it to test UI elements properly. Be sure to check it out and make good use of it.
  5. Unity integrationmhall119: Michael Hall, the author of “Hello Unity” and things like “singlet” knows how Unity works and how best to integrate your apps with it. It’s these finishing touches which make your app stand out and give the users the nice feeling of a seamless experience.

Here’s what’s on for today. Hope to see you all there!

Ubuntu Developer Week is over – thanks everyone

Thanks a lot to all the presenters at Ubuntu Developer Week! Thanks a lot also to everyone who joined the sessions and who helped set them up. This UDW was another great success. We had up to 300 people sessions around at peak times, lots of great questions and lots of excitement. It’s events like this where you can get a better sense how Ubuntu development works, can see Open Source development in action and get to know the people.

All the logs of the sessions are now available from the Ubuntu Developer Week page. Thanks again everyone!

Here’s a run through the sessions of the last day:

  • Getting started with app development and Intro to translations in Ubuntu – David Planella talked about two topics very close to his heart, Apps in Ubuntu and Translations in Ubuntu. Within 30 minutes each, he managed to give a nice overview and also to address all incoming questions.
  • Adding test cases with UTAH and Q&A about test automation  – UTAH is the Ubuntu Test Automation Harness and Gema Gomez-Solano explained in quite some detail how it works and why this changes how we put Ubuntu together a lot. She also explained how to get involved by adding new test-cases. Please have a look at the logs and help out!
  • Getting started with Ubuntu WebApps – Alex Launi and Alex Abreu did a great job explaining how Ubuntu WebApps works and how to get started implementing your own. It’s great to see how easily the Desktop and the Web can get closer. Be sure to check it out.
  • u1db: synced data for your apps on many platforms – The Ubuntu One team has been cooking something really nice for us and Stuart Langridge showed trivial it is to get up and running with your own databases. It’s a great and very natural way to use, store and sync data, in any application.
  • Developers Roundtable – Benjamin Drung and Scott Kitterman were around to answer all kinds of development-related questions and did a nice job of easing everyone into a comfortable atmosphere. Particularly talking from their own experience is nice to read.

Ubuntu Developer Week always flies by much too quickly, but there will be more events related to Ubuntu development, so stay tuned.

Ubuntu Developer Week – last day ahead, summary of day 2

Day 2 is over and what a fantastic day it was! Without further ado here’s the summary of day 2:

  • Introduction to Quickly – Michael Terry rocked it. As he is one of the maintainers of Quickly it was easy for him to give a nice overview of our favourite app development tool and answer all questions which came up.
  • Getting help to start with Ubuntu Development The developer advisory team and beyond – As member of the MOTU team and the Developer Advisory Team, Bhavani Shankar knows what kind of questions and concerns new contributors have. He did a great job explaining how the DAT tries to help newcomers and explain what to watch out for when getting involved with Ubuntu Development.
  • Fixing small bugs and forwarding the patches upstream – Stefano Rivera filled multiple pages with content during his session and explained very nicely where to find easy tasks to work on and which typical bug fixing initiatives are going on in Ubuntu and Debian.
  • libmessagingmenu – As a new member of the Desktop infrastructure it was great to see libmessagingmenu explained by somebody who put lots of work into it. Thanks Lars Uebernickel – now it should be easier to integrate with libmessagingmenu for interested developers.
  • Ubuntu Juju Tips and Tricks – With Ubuntu’s focus on the Cloud world, we had to have a session about Juju. Read the log and see how Mark Mims went into detail about how to get the most out of it.

I’m sure you’re as sad as everybody else, but today is the last day of Ubuntu Developer Week. Don’t despair though, there’ll be many many more. Here’s what’s up on the schedule for today:

  1. 15:00 UTC: Getting started with app development – David Planella has been working with the App Developer community for quite a while, so he knows the pitfalls and problems you might run into when writing your first app.
  2. 15:30 UTC: Intro to translations in Ubuntu – David has also worked with the Translations community a lot, so stay tuned for a great session on making software speak all kinds of languages.
  3. 16:00 UTC: Adding test cases with UTAH – Quick introduction to Ubuntu Test Automation Harness. How to get involved, and how to get support from the development team or contribute.
  4. 16:30 UTC: Q&A about test automation – Answers for anyone with questions about starting a new automated suite, where to start with automation (with or without UTAH) of package testing, feel free to come over and ask. If there are no questions there won’t be any answers either!
  5. 17:00 UTC: Getting started with Ubuntu WebApps – Getting the Ubuntu Desktop closer to the web was a huge undertaking, but totally worth it. Ubuntu is just so much better with all the goodness being closely integrated. Alex Launi and Alex Abreu are experts on the topic.
  6. 18:00 UTC: u1db: synced data for your apps on many platforms – If your app deal with any kind of data, you might be interested in hooking it up with Ubuntu One DB. Stuart Langridge will tell you exactly ho.
  7. 19:00 UTC: Developers Roundtable – Do you have questions about Ubuntu development? Here you have the best opportunity to ask everything you want to know, because we will have a number of developers there who can answer your questions for you.

We hope to see many of you around today as it’s the last day. Tell your friends and bring them and your questions. Join in!

Ubuntu Developer Week – Summary Day 1, Outlook Day 2

Day 1 of Ubuntu Developer Week is over – it was brilliant. Lots of people, last I looked it was close to 300 and many many excellent questions. Here’s a quick run through the sessions we had yesterday:

  • Introduction to Ubuntu development – The even was started by Daniel Holbach, who gave a one-hour introduction to Ubuntu development. Many of the things you need to understand first were discussed, but lots more as well. Especially the Q&A parts are an interesting read.
  • Getting set up for Ubuntu development – After a very short break, just enough to get a cup of tea, the session continued and we talked about all the tools a developer typically needs and how to set them up properly. This as well raised many good questions. Reading through the log you can get a sense for how our attendees were interested in getting started.
  • Something about ARM – Oliver Grawert was up next and started off with a brief history of how the efforts around ARM evolved in Ubuntu. The rest of the session was very much about questions and answers and by getting through them all, it was very easy to understand how busy a place ARM in Ubuntu is.
  • Ubuntu Development for the Youth – Bilal Akhtar gave an excellent session about contributing to Ubuntu and answered many very common questions and was able to put many minds at ease. If you should be still unsure about Ubuntu development and if it’s a good idea to get involved, read the session log.
  • Using and porting to Python3 – Barry Warsaw could have filled three hours about Python3 without problems. The session was very interesting as he managed to highlight both challenges with porting from 2 to 3, but also what we have to gain.

Very soon we will kick off day 2 which has this for us in store:

  1. 15:00 UTC: Introduction to Quickly – Michael Terry is one of the people behind Quickly, so he’s a pretty good person to get you started writing your first app for Ubuntu. Prepare yourself for a pleasant journey towards your first app.
  2. 16:00 UTC: Getting help to start with Ubuntu Development – The developer advisory team and beyond – Bhavani Shankar has been part of Ubuntu Development for a very long time and part of the Developer Advisory Team for almost all of its lifetime. Join his session for an overview of what the DAT is doing and some tips to get started.
  3. 17:00 UTC: Fixing small bugs and forwarding the patches upstream – Stefano Rivera is both, an Ubuntu and a Debian developer, and has contributed to both for an extended period of time. He’d love you to help fix small bugs in both, so join in, ask your questions and get involved.
  4. 18:00 UTC: libmessagingmenu – libmessagingmenu is one of the key components on the Ubuntu Desktop and Lars Übernickel a person who knows everything about it. His session will give you a good idea how it works and how to integrate with it easily.
  5. 19:00 UTC: Ubuntu Juju Tips and Tricks –  juju has taken the DevOps world by storm, because it was never easier to massage your knowledge about the deployment and administration of services into charms and to administer many many systems very easily. Mark Mims will be here to tell us more about it.

As you can see, we brought together all kinds of Ubuntu developers to give you a taster of the richness of our community. Tell your friends and bring them and your questions. Join in!

  • What’s a debian/watch file good for?
  • Porting your code to Python 3
  • pkgme and what it can do for you
  • UDD, quilt and bzr and how to make the most of it
  • Using autopkgtest and jenkins for fun and profit
  • Demo: fixing bugs
  • Demo: updating packages to a new upstream version
  • Demo: getting stable release updates right

Just grab one of the above or think of your own session topic idea and add it to the timetable.

Developer Week: Summary Day 3

It’s sad news, yes – Ubuntu Developer Week for the 12.04 cycle is over. It’s been three fantastic days full of action-packed sessions. If you couldn’t attend, check out the logs of the sessions, all of them are posted on the UDW page.

Here’s what happened on day 3, yesterday:

  1. Fixing Desktop bugsseb128Sébastien Bacher kicked off our last day. At first he took some time to explain how the Desktop team works and how they go about fixing bugs, then he took a quite recent example and explained how to work all the individual packaging bits to fix a Desktop bug in Ubuntu. For bonus points he explained how to get Wanda the Fish working in Ubuntu.
  2. Triaging Desktop bugsom26erNext up was Omer Akram, who first gave us an update about his personal life, then quickly dived into triaging bugs. He explained all the actors involved, what to bear in mind and general things to make sure when you are reviewing bug reports. Omer, who started out by triaging bugs himself, did a great job explaining how to get involved and why it’s so important.
  3. Simple Lenses with Singletmhall119Michael Hall, an unstoppable force throughout UDW, provided a great session about how to write lenses for Unity using Singlet. For developers who have used Python in the past, this might be an even easier (and more pythonic way) to interact with Unity and Desktop bits.
  4. Building locally with pbuildertumbleweed
    Those of you venturing into the land of Ubuntu development will have to deal with packaging and it’s good to do it in a safe, clean and reproducible manner. Stefano Rivera explained a lot of options for doing that including some advanced features useful if you want to debug builds. Great work.
  5. Writing Crisp Changelogscoolbhavi
    Again for those of you interested in package maintenance: it’s important to document your work properly. You don’t want anybody (including yourself) having to go back in a few months or years and dive into the archaelogy of a package to understand what exactly was changed and why. Bhavani Shankar shared his experience in writing crisp changelog entries.
  6. Getting started with contributing to Ubuntu Documentationjbicha
    The Ubuntu Documentation project is of vital importance to everyone who is new to Ubuntu. Also is it a great way to get involved with Ubuntu, as Jeremy Bicha showed. He explained how to the team works generally and how to actually go and contribute improvements.
  7. Adding Ubuntu One to your applicationsaquarius
    If you want to allow you application to sync data to the internet, it never was easier. Stuart Langridge showed and explained some easy examples which demoed how to tie in Ubuntu One services into your app.
  8. Pair Programming and Code Review in the Cloud!kirkland
    Dustin Kirkland did an impressive live demo of how to use EC2 to do pair programming, review of code and builds. He used tmux and byobu and explained in detail how to drive the infrastructure. Unfortunately the log is a bit colourless without the live demo right next to it.
  9. Syncing your app data everywhere with U1DBaquarius
    Nothing stops Stuart Langridge when he’s on a roll. He delivered his second session all about the new Ubuntu One Database. For those of you new to the initiative: “U1DB is for syncing data — that is, something structured — to every device you want”. The session is short, has lots of good information in it and a nice example of how to work with it.
  10. Automated packaging with pkgmejames_w
    James Westby gave a great introduction to the pkgme project he has been working on and it’s fantastic to see that a lot of repetitive tasks are done by a tool. It was nice to see pkgme package itself. Give it a whirl and let James know how it works out for you.
  11. Fixing internationalisation bugskelemengabor
    Gábor Kelemen is one of the heroes of Ubuntu’s internationalisation. Keeping all packages translatable and translations in shape matters deeply to him and he gave a nice overview over how common problems can easily be resolved. Köszönöm Gábor!
  12. How to fix small bugs in Ubuntuwarp10
    Andrea Colangelo took over and quickly ran us through a couple of examples of fixed bugs and explained how exactly they were fixed. By the end of the session it was clear that in a lot of cases it’s no rocket science to go and fix a bug. Grazie mille, Andrea – I hope many will find your session as encouraging as we did.
  13. Problem Lifecycle in Ubuntucprofitt
    Charles Profitt delivered the last session of the event and explained how all teams in Ubuntu work together to go from problem to solution, involving the lifecycle of a bug report, which was a big enough topic on its own already. Throughout the session he showed how you can join each of the teams and make a difference. Awesome!

What a fantastic day. Thanks a lot to all the speakers who made this Ubuntu Developer Week possible. Thanks a lot to everyone who attended as well. It was great to see a lot of interaction, questions and interest. Until next time! 🙂
